Description

本発明は，ウッドデッキやフローリングの床板であって，幅方向両端面を成す側面に床板の長さ方向にスリットが形成された床板を根太等の支持材上に固定するための床板固定具に関し，特に合成木材製の床板の固定に適した床板固定具に関する。 The present invention relates to a floorboard fixture for fixing a floorboard, such as a wood deck or flooring, in which slits are formed in the lengthwise direction of the floorboard on the side surfaces forming both ends in the width direction on a support material such as joists, In particular, the present invention relates to a floor board fixture suitable for fixing a synthetic wood floor board.

ウッドデッキを例として説明すると，このウッドデッキの施工は，一例として図７に示すように地表等に必要に応じて基礎を打設する等した設置面９上に束柱６を立設し，この束柱６上に根太等の支持材５を架設し，この支持材５上に床板４であるデッキパネルを,所定間隔を介して一定方向に並行に並べて載置すると共に，この床板４を，前記支持材５に固定することにより行われる。 As an example, the construction of this wood deck is as follows. As shown in FIG. 7, as shown in FIG. 7, a bundle column 6 is erected on an installation surface 9 where a foundation is placed on the ground surface as necessary. A support material 5 such as a joist is installed on the pillar 6, and a deck panel, which is a floor plate 4, is placed on the support material 5 side by side in parallel in a certain direction at a predetermined interval. It is performed by fixing to the support material 5.

支持材５に対して床板４を固定する最も簡単な手段としては，図８に示すように床板４の表面から支持材５に至る釘や螺子釘７’を打ち込み，この釘や螺子釘によって床板４を支持材５に直接止め付ける手段がある。 As the simplest means for fixing the floor plate 4 to the support material 5, as shown in FIG. 8, a nail or a screw nail 7 'extending from the surface of the floor plate 4 to the support material 5 is driven and the floor plate is used by this nail or screw nail. There is means for directly fastening 4 to the support material 5.

しかし，この手段による場合，床板４の表面に釘や螺子釘７’の頭部が露出するために見栄えが悪く，また，経時により釘や螺子釘の頭部が床板４の表面より突出した場合には，床板上を歩行等する際に危険を伴う。 However, when this means is used, the head of the nail or screw nail 7 ′ is exposed on the surface of the floor plate 4, so that the appearance is bad, and the head of the nail or screw nail protrudes from the surface of the floor plate 4 over time. Is dangerous when walking on the floorboard.

さらに，一旦施工された床板４は，これを取り外した際，床板４の表面に釘や螺子釘によってうがたれた穴が残ることから，例えば解体された家屋等より回収した使用済みの床板を再利用しようとすれば，この孔を埋める等の煩雑な作業が必要となる。 Further, once the floorboard 4 once constructed is removed, a hole sagged by a nail or a screw nail remains on the surface of the floorboard 4, so that a used floorboard collected from a dismantled house , for example, is removed. If it is to be reused, complicated work such as filling the hole is required.

そこで，図９（Ａ），（Ｂ）に示すように釘や螺子釘を床板４の表面に直接打ち込むことなく，床板固定具１００，１１０を使用して支持材５に床板４を取り付ける手段も提案されており，このような床板固定具１００，１１０による取り付けを可能とするために，床板４の幅方向における両端を成す側面４０に，床板４の長さ方向に連続したスリット４１を形成し，このスリット４１に嵌合させた床板固定具１００，１１０を支持材５に固定することで，支持材５に対する床板４の固定を行うことも提案されている。 Therefore, as shown in FIGS. 9A and 9B, there is also a means for attaching the floor plate 4 to the support member 5 using the floor plate fixtures 100 and 110 without directly driving a nail or screw nail into the surface of the floor plate 4. In order to enable the attachment by the floor plate fixtures 100 and 110, slits 41 that are continuous in the length direction of the floor plate 4 are formed on the side surfaces 40 that form both ends of the floor plate 4 in the width direction. It has also been proposed to fix the floor plate 4 to the support member 5 by fixing the floor plate fixtures 100 and 110 fitted in the slit 41 to the support member 5.

このように，床板４を支持材５に固定するために，上端開口縁より外向きに突出したフランジ部１０１を設けた長尺のチャンネル金具を床板固定具１００として使用し，この床板固定具１００のフランジ部１０１を，隣接配置された床板４の対向する側面４０に形成されたスリット４１内にそれぞれ挿入すると共に，長手方向に所定の間隔で底板に形成された釘孔１０２に挿入された螺子釘７’をそれぞれ支持材５に打ち込む（ねじ込む）ことで，床板固定具１００を介して床板４を支持材５に固定する手段〔図９（Ａ）参照〕，他に，架橋片１１１と該架橋片１１１の裏面より突出した中間片１１２を備えた断面Ｔ字状の床板固定具１１０を使用し，この床板固定具１１０の架橋片１１１を床板４のスリット４１内に挿入すると共に，中間片１１２を同図上下方向に貫通する釘孔１１３に挿入した螺子釘７’を支持材５に打ち込む（ねじ込む）ことで，床板４を支持材５に固定する手段も提案されている〔図９（Ｂ）参照〕。 In this way, in order to fix the floor plate 4 to the support member 5, a long channel fitting provided with the flange portion 101 protruding outward from the upper end opening edge is used as the floor plate fixture 100. Are inserted into the slits 41 formed in the opposite side surfaces 40 of the floor plate 4 arranged adjacent to each other, and the screws inserted into the nail holes 102 formed in the bottom plate at predetermined intervals in the longitudinal direction. Means for fixing the floor plate 4 to the support member 5 via the floor plate fixture 100 (see FIG. 9A) by driving (screwing) the nails 7 'into the support member 5, respectively. A floor board fixture 110 having a T-shaped cross section provided with an intermediate piece 112 projecting from the back surface of the bridge piece 111 is used, and the bridge piece 111 of the floor board fixture 110 is inserted into the slit 41 of the floor board 4, Means for fixing the floor plate 4 to the support member 5 by driving (screwing) the screw nail 7 ′ inserted into the nail hole 113 penetrating 112 in the vertical direction in FIG. See B)].

なお，図９（Ａ）を参照して説明した床板固定具１００の構造において，更に図１０に示すようにフランジ部１０１の先端に鋸歯状の端縁を有する係止爪１０３を形成し，螺子釘７’による固定時，係止爪１０３が床板４のスリット４１の内壁に食い込むようにしたものや（特許文献１；図１０参照），図９（Ｂ）を参照して説明した床板固定具１１０の構造において，支持材５に対して螺子釘７’を締め込んで行くと変形が生じ，この変形によって床板４に設けたスリット４１の内壁との接触抵抗を増大させるようにした床板固定具１１０も提案されている（特許文献２：図１１参照）。 In addition, in the structure of the floor plate fixture 100 described with reference to FIG. 9A, a locking claw 103 having a sawtooth edge is formed at the tip of the flange 101 as shown in FIG. When the nail 7 ′ is fixed, the locking claw 103 bites into the inner wall of the slit 41 of the floor board 4 (Patent Document 1; see FIG. 10), or the floor board fixing tool described with reference to FIG. In the structure of 110, when the screw nail 7 'is tightened with respect to the support member 5, deformation occurs, and this deformation increases the contact resistance with the inner wall of the slit 41 provided in the floor plate 4. 110 is also proposed (see Patent Document 2: FIG. 11).

特開２００２−１４６９０１号公報JP 2002-146901 A 特開２００８−２８５９２９号公報JP 2008-285929 A

前述した床板４の固定手段において，図９（Ａ），（Ｂ）を参照して説明した固定手段によれば，床板４を支持材５より上方に引きはがそうとしても，床板４の側面４０に形成したスリット４１の内壁が，床板固定具１００，１１０のフランジ部１０１乃至は架橋片１１１と接触するために，床板４は，支持材５上に固定されてこれを引き剥がすことはできない。 In the fixing means for the floor plate 4 described above, according to the fixing means described with reference to FIGS. 9A and 9B, the side surface of the floor plate 4 can be removed even if the floor plate 4 is pulled upward from the support material 5. Since the inner wall of the slit 41 formed in 40 is in contact with the flange portion 101 or the bridging piece 111 of the floor plate fixtures 100 and 110, the floor plate 4 is fixed on the support material 5 and cannot be peeled off. .

しかし，このような床板固定具１００，１１０による固定では，床板４と床板固定具１００，１１０間の直接的な連結を行っていないために，床板４を上方に引き剥がせないようにする点では効果的であるものの，床板４の長手方向の移動を規制する力が弱い。 However, in such fixing by the floor plate fixtures 100 and 110, since the direct connection between the floor plate 4 and the floor plate fixtures 100 and 110 is not performed, the floor plate 4 cannot be peeled upward. Although effective, the force for regulating the movement of the floor plate 4 in the longitudinal direction is weak.

そのため，このようにして固定された床板４上を人が歩く等して，床板４を長手方向に移動させる力が加わると床板が長手方向に移動して外れてしまうおそれがあり，例えば床板４の長手方向における両端側に，床板４の端部に突合して床板の移動を規制する横木を設ける等の対策が必要となる。 Therefore, when a person walks on the floor plate 4 fixed in this manner and a force for moving the floor plate 4 in the longitudinal direction is applied, the floor plate may move in the longitudinal direction and come off. For example, the floor plate 4 It is necessary to take measures such as providing cross bars that butt against the ends of the floor board 4 and restrict the movement of the floor board at both ends in the longitudinal direction.

しかし，このようにして横木を設けることで床板４の端部が横木を越えて移動できないようにしても，床板４の端部と横木との間には，気温や湿度の変化に伴う床板４の膨張，収縮等を考慮して若干の隙間を設ける必要があるために，人が歩く度に床板４がこの隙間分長手方向に移動して床板４の端部が前述した横木に衝突すれば，この衝突により騒音が発生し，ひいては，ゆがみなどの変形，破損が生ずる。 However, even if the end of the floor plate 4 cannot be moved beyond the cross by providing the cross in this manner, the floor plate 4 between the end of the floor 4 and the cross is caused by changes in temperature and humidity. When a person walks, the floor board 4 moves in the longitudinal direction and the end of the floor board 4 collides with the above-mentioned cross board. , This collision generates noise, which in turn causes deformation and damage such as distortion.

図１０に示した特許文献１に記載の床板固定具１００にあっては，フランジ部１０１に設けた係止爪１０３を床板４のスリット４１内壁に食い込ませることで隣接する床板４間を連結しようというものであり（特許文献１の「0055」欄），係止爪１０３を設けることにより，床板固定具１００に「かすがい」に類似した機能を付与しようというものであるが，このような係止爪１０３を設け，これを床板４に食い込ませた場合には，床板４と床板固定具１００とが強固に連結されることとなる結果，この床板固定具１００を使用する場合には，床板４が長手方向に移動することも効果的に防止し得るものと考えられる。 In the floorboard fixture 100 described in Patent Document 1 shown in FIG. 10, the engaging claws 103 provided on the flange portion 101 are bitten into the inner wall of the slit 41 of the floorboard 4 to connect adjacent floorboards 4. (Column “0055” in Patent Document 1), and by providing the locking claw 103, the floor plate fixture 100 is to be given a function similar to “smear”. When the pawl 103 is provided and bites into the floor board 4, the floor board 4 and the floor board fixture 100 are firmly connected. As a result, when the floor board fixture 100 is used, It is considered that 4 can be effectively prevented from moving in the longitudinal direction.

しかし，床板４，特に合成木材によって形成された床板４は，気温の変化や水分の吸収状態等によって比較的大きな寸法変化を生じ，特に，床板４の長手方向における寸法変化は大きい。例えば，６ｍの木質合成板で，以下のとおりとなる。

However, the floor board 4, particularly the floor board 4 formed of synthetic wood, undergoes a relatively large dimensional change due to changes in temperature, absorption of moisture, etc., and the dimensional change in the longitudinal direction of the floor board 4 is particularly large. For example, a 6m wood composite board is as follows.

そのため，図１０の床板固定具１００のように，係止爪１０３を床板４に食い込ませる等して床板４と床板固定具１００とを強固に連結してしまうと，膨張や収縮による床板４の寸法変化を吸収できず，床板固定具１００に大きな力が加わって床板固定具１００の破損や変形，螺子釘７’の抜け落ちが生じて床板４の固定ができなくなり，また，床板４に反りや歪み等の変形が生じるおそれがある。 Therefore, as in the floor plate fixture 100 of FIG. 10, if the floor plate 4 and the floor plate fixture 100 are firmly connected by, for example, biting the locking claw 103 into the floor plate 4, The dimensional change cannot be absorbed, and a large force is applied to the floor plate fixture 100 to cause breakage and deformation of the floor plate fixture 100, and the screw nail 7 'comes off, and the floor plate 4 cannot be fixed. There is a risk of deformation such as distortion.

そのため床板固定具には，人が歩行等した際に加わる通常の使用状態においてかかる負荷の程度では床板４の移動を規制して固定することができるが，床板４の膨張や収縮により床板４自体に寸法変化が生じた場合等，床板固定具を破損させてしまう程の大きな力で床板４を動かそうとする力が加わった場合には，床板４の移動を許容し得るように床板４を固定できるものであることが望まれる。 Therefore, the floor plate 4 can be fixed by restricting the movement of the floor plate 4 in a normal use state applied when a person walks or the like, but the floor plate 4 itself can be fixed by expansion or contraction of the floor plate 4. When a force for moving the floor plate 4 is applied with a force large enough to damage the floor plate fixture, such as when a dimensional change occurs, the floor plate 4 is moved so that the floor plate 4 can be allowed to move. It is desirable that it can be fixed.

このような要求に対して，図１１を参照して説明した特許文献２に記載の床板固定具１１０にあっては，床板固定具１１０を樹脂材料等の可撓性材料によって形成し，螺子釘７’の締め込みを行うことにより床板固定具１１０を変形させて床板４の側面４０に設けたスリット４１の内壁に対する架橋片１１１の押圧力を高めて床板４の長手方向への移動を規制することにより，床板４上を人が歩行する等の通常の使用状態で加わる力では床板４が移動することはないが，膨張や収縮等によって床板４の寸法自体が変化した場合のように極めて大きな力が加わった場合には，この寸法変化に伴う床板４の移動を許容することができるように構成している。 In response to such a requirement, in the floorboard fixture 110 described in Patent Document 2 described with reference to FIG. 11, the floorboard fixture 110 is formed of a flexible material such as a resin material, and screw nails are formed. The floor plate fixture 110 is deformed by tightening 7 'to increase the pressing force of the bridging piece 111 against the inner wall of the slit 41 provided on the side surface 40 of the floor plate 4, thereby restricting the movement of the floor plate 4 in the longitudinal direction. Therefore, the floor plate 4 does not move by a force applied in a normal use state such as a person walking on the floor plate 4, but it is extremely large as in the case where the dimension of the floor plate 4 itself changes due to expansion or contraction. When force is applied, the floor plate 4 can be allowed to move with this dimensional change.

しかし，前掲の特許文献２に記載の床板固定具１１０では，床板固定具１１０に変形を生じさせるために，好適な実施形態において中間片１１２に切欠を形成し，あるいは，架橋板１１１に厚肉部と薄肉部とを形成する構成を採用する等，その形状が複雑なものとなっている。 However, in the floor board fixture 110 described in the above-mentioned Patent Document 2, in order to cause the floor board fixture 110 to be deformed, in the preferred embodiment, a cutout is formed in the intermediate piece 112 or the bridge plate 111 is thick. The shape is complicated, for example, by adopting a configuration in which a portion and a thin portion are formed.

なお，螺子釘７’の頭部が床板４間に形成された隙間内に隠れるように施工するためには，図９（Ａ）及び図１０を参照して説明した床板固定具１００では，螺子釘７’として頭部の直径ｒが床板固定具１００に形成された溝幅Ｗ1以下のものを使用する必要があり，また，図９（Ｂ）及び図１１を参照して説明した床板固定具１１０にあっては，頭部の直径ｒを，隣接する床板４の側面４０間の間隔（以下，この間隔を「目地幅」という。）Ｗ2以下の螺子釘を使用する必要がある。 In order to perform construction so that the head of the screw nail 7 ′ is hidden in the gap formed between the floor plates 4, the floor plate fixture 100 described with reference to FIGS. It is necessary to use a nail 7 ′ having a head diameter r equal to or less than the groove width W 1 formed in the floor plate fixture 100, and the floor plate fixture described with reference to FIGS. 9B and 11. In 110, it is necessary to use a screw nail whose head diameter r is equal to or less than the interval between side surfaces 40 of adjacent floor plates 4 (hereinafter, this interval is referred to as “joint width”).

そのため，床板４の目地幅Ｗ2を比較的狭く施工しようとすれば，必然的に使用する螺子釘７’の頭部直径ｒも小さくなるために，ドライバ等の工具からのトルクによって頭部に形成された工具嵌合用の窪みが変形してしまい，その結果螺子釘７’を締め込むことができなくなる。 Therefore, if the joint width W2 of the floor plate 4 is set to be relatively narrow, the head diameter r of the screw nail 7 'to be used is inevitably reduced, so that it is formed on the head by torque from a tool such as a driver. The tool fitting recess thus formed is deformed, and as a result, the screw nail 7 'cannot be tightened.

一方，図９（Ｂ）及び図１１を参照して説明した床板４の固定において，敢えて目地幅Ｗ2に対して頭部の直径ｒが大きな螺子釘を使用した場合には，この螺子釘７’を締め込む際に，螺子釘７’頭部が床板４の側面４０を削り取るために，施工後の見栄えが悪くなり，見栄えを向上させるために螺子釘７’の頭部が削り取った部分をパテ等で埋めて補修等しようとすれば，多大な労力が必要となる。 On the other hand, in the fixing of the floor plate 4 described with reference to FIGS. 9B and 11, when a screw nail having a large head diameter r with respect to the joint width W2 is used, this screw nail 7 ' When the screw nail 7 is tightened, the head part of the screw nail 7 'scrapes off the side surface 40 of the floor plate 4, so that the appearance after construction deteriorates. In order to improve the appearance, the part of the screw nail 7' head shaved off is putty. If you try to repair it by filling it in, etc., you will need a lot of labor.

なお，このように床板４の側面４０が削り取られることは，頭部の直径が目地幅に対して小さい螺子釘７’を使用した場合であっても，螺子釘７’が斜めに打ち込まれる等した場合には同様に生じ得るものとなっている。 It should be noted that the side surface 40 of the floor plate 4 is scraped off in this way even when the screw nail 7 'whose head diameter is smaller than the joint width is used, the screw nail 7' is driven obliquely, etc. If this happens, it can occur in the same way.

本発明は，上記従来技術における欠点を解消するためになされたものであり，比較的簡単な構造でありながら，人が床板上を歩行等した場合等，通常の使用状態で生じる外力が床板に加わった場合には，床板の長手方向の移動を規制するが，床板が膨張，収縮することにより寸法変化が生じた場合のように，極めて強固な力によって床板固定具との接触位置を長手方向に移動させようとする力が生じた場合には，このような移動を許容することができる床板固定具を提供することを目的とする。 The present invention has been made to eliminate the above-mentioned drawbacks of the prior art. Although the structure is relatively simple, an external force generated in a normal use state, such as when a person walks on the floor board, is applied to the floor board. If it is added, the movement of the floorboard in the longitudinal direction is restricted, but the contact position with the floorboard fixture is moved in the longitudinal direction by a very strong force, as in the case of a dimensional change caused by expansion and contraction of the floorboard. It is an object of the present invention to provide a floor plate fixture that can allow such movement when a force to move it is generated.

また，本発明は，上記目的に加え，床板固定具を支持材に固定する螺子釘として頭部の直径が可及的に大きなものを使用することができ，且つ，このような頭部の直径が大きい螺子釘を使用した場合であっても，螺子釘の頭部を床板の表面より突出させることなく，且つ，床板の幅方向における側面を螺子釘の頭部によって削ることなく施工することのできる床板固定具を提供することを目的とする。 In addition to the above object, the present invention can use a screw nail for fixing the floor plate fixture to the support member having a head having the largest possible diameter, and such a head diameter. Even when a large screw nail is used, the screw nail head should not protrude from the surface of the floor plate, and the side surface in the width direction of the floor plate should not be cut by the screw nail head. An object of the present invention is to provide a floor plate fixture that can be used.

上記構成の床板固定具１において，平面視における前記各凸条２２，２２’の頂部２２ａ形状を尖鋭状に形成し，前記凸条２２，２２’が形成された前記スペーサ片２の側面２３を鋸歯状に形成することができる（請求項２）。 In the floor plate fixture 1 having the above configuration, the shape of the apex 22a of each of the ridges 22 and 22 'in plan view is formed in a sharp shape, and the side surface 23 of the spacer piece 2 on which the ridges 22 and 22' are formed is formed. It can be formed in a sawtooth shape (claim 2).

更に，このように凸条２２，２２’の頂部２２ａを尖鋭状に形成した場合には，前記各凸条２２の頂部２２ａを，前記凸条２２の幅方向における一方側に偏って配置した構成としても良い〔請求項３；図２（Ｄ）中の拡大図参照〕。 Further, when the top portions 22a of the ridges 22 and 22 'are formed in a sharp shape as described above, the top portions 22a of the respective ridges 22 are arranged so as to be biased toward one side in the width direction of the ridges 22. [Claim 3; see the enlarged view in FIG. 2D].

また，前記架橋片３の下端から前記スペーサ片２の下端迄の長さｌ〔図１（Ａ）参照〕を，固定対象とする前記床板４の裏面から前記スリット４１の床板裏面側内壁４１ａ迄の高さＬ（図５参照）に対して僅かに短く形成するものとしても良い（請求項４）。 Further, the length l from the lower end of the bridging piece 3 to the lower end of the spacer piece 2 (see FIG. 1A) is from the rear surface of the floor plate 4 to be fixed to the inner surface 41a on the floor plate rear surface side of the slit 41. It may be formed slightly shorter than the height L (see FIG. 5).

以上で説明した本発明の構成により，本発明の床板固定具１によれば，以下の効果を得ることができた。 With the configuration of the present invention described above, according to the floor board fixture 1 of the present invention, the following effects can be obtained.

架橋片３の裏面側のみならず，上面側にも床板４の側面４０に挟持されるスペーサ片２を設けることにより，床板固定具１が断面において十字状〔図１（Ｂ）参照〕に形成されていることにより，床板固定具１と床板４との接触面積の増大が得られていると共に，スペーサ片２の側面２３に複数の凸条２２を設けたことにより，床板固定具１と床板４との接触抵抗を大幅に増大させることができた。 By providing the spacer piece 2 sandwiched by the side surface 40 of the floor board 4 not only on the back surface side but also on the upper surface side of the bridge piece 3, the floor board fixture 1 is formed in a cross shape in cross section [see FIG. 1 (B)]. As a result, an increase in the contact area between the floor plate fixture 1 and the floor plate 4 is obtained, and a plurality of ridges 22 are provided on the side surface 23 of the spacer piece 2, whereby the floor plate fixture 1 and the floor plate are provided. The contact resistance with 4 could be greatly increased.

その結果，床板４と床板固定具１とを直接固定することなく，両者の接触抵抗によって床板４上を人が歩行する等の通常の使用状態において加わる力に対して床板４が長手方向に移動することを十分に防止することができる一方，床板４の膨張や収縮に伴う寸法変化が生じた場合のように，極めて強い力で床板４と床板固定具１との接触位置を移動させようとする力が加わった場合には，床板４の移動を許容することができ，床板の膨張，収縮等に伴う床板固定具１の破損や螺子釘７の脱落，床板４に反りや歪み等の変形が発生することを好適に防止することができた。 As a result, the floor plate 4 moves in the longitudinal direction against the force applied in a normal use state such as a person walking on the floor plate 4 by the contact resistance between the floor plate 4 and the floor plate fixture 1 without being directly fixed. On the other hand, the contact position between the floor plate 4 and the floor plate fixture 1 is moved with a very strong force, such as when a dimensional change occurs due to expansion or contraction of the floor plate 4. When a force is applied, the floor plate 4 can be allowed to move, and the floor plate fixture 1 is damaged due to the expansion and contraction of the floor plate, the screw nail 7 is dropped, the floor plate 4 is deformed such as warping and distortion. It was possible to suitably prevent the occurrence of.

床板固定具１の平面視において，前記凸条２２，２２’の頂部２２ａを尖鋭状に形成して，スペーサ片２の側面２３を鋸歯状とした構成にあっては，床板４と床板固定具１との接触抵抗を更に増大させることができ，床板４上を人が歩行する等の通常の使用状態における床板４の長手方向における移動を更に確実に防止することができた。 In the plan view of the floor plate fixture 1, when the top portions 22 a of the ridges 22, 22 ′ are formed in a sharp shape and the side surface 23 of the spacer piece 2 is serrated, the floor plate 4 and the floor plate fixture The contact resistance with 1 can be further increased, and the movement of the floor board 4 in the longitudinal direction in a normal use state such as a person walking on the floor board 4 can be further reliably prevented.

特に，この凸条２２の頂部２２ａを，凸条２２の幅方向における一方側に偏って配置した構成にあっては，床板４の長手方向のいずれか一方向きの移動に対し，より強力に規制することができる床板固定具１を提供することができた。 In particular, in the configuration in which the top portion 22a of the ridge 22 is arranged to be deviated to one side in the width direction of the ridge 22, the movement of the floor plate 4 in one direction in the longitudinal direction is more strongly regulated. The floor board fixture 1 which can be provided was able to be provided.

架橋片３の下端からスペーサ片２の下端迄の長さｌを，床板４の裏面からスリット４１の裏面側内壁４１ａ迄の高さＬに対して短く形成した場合には，螺子釘によって床板固定具１を支持材５上に取り付けた際，架橋片３の下端がスリットの裏面側内壁４１ａに対して強固に押圧されることで，膨張，収縮に伴う床板の長手方向への移動を許容しつつ，床板の固定を強固に行うことができた。 When the length l from the lower end of the bridging piece 3 to the lower end of the spacer piece 2 is made shorter than the height L from the back side of the floor plate 4 to the back side inner wall 41a of the slit 41, the floor plate is fixed by screw nails. When the tool 1 is mounted on the support member 5, the lower end of the bridging piece 3 is firmly pressed against the inner wall 41a on the back side of the slit, thereby allowing the floor plate to move in the longitudinal direction accompanying expansion and contraction. However, the floorboard could be firmly fixed.

表面側における幅方向両端の角部が面取りされて面取り部４３が形成された床板４を固定対象とし，前記架橋片３の下端から前記釘孔の形成位置における前記スペーサ片２の上端迄の高さｈを，固定対象とする前記床板４の裏面側内壁４１ａから前記面取り部４３の下端４３ｂ迄の高さと略同一に形成した床板固定具１にあっては，支持材５に対する床板固定具１の固定に隣接する面取り部４３の上端４３ａ間の幅に対して直径ｒが小さな頭部７１を有する皿螺子を使用することで，目地幅Ｗ2よりも大きな直径ｒの頭部７１を有する皿螺子を使用することができ，これにより螺子釘７の頭部に形成された工具嵌合用の窪みが破損する等といった問題の発生を減少させることができた。 The floor plate 4 in which the corners at both ends in the width direction on the surface side are chamfered and the chamfered portion 43 is formed is to be fixed, and the height from the lower end of the bridging piece 3 to the upper end of the spacer piece 2 at the nail hole forming position is set. In the floor plate fixture 1 formed with the height h substantially the same as the height from the back side inner wall 41a of the floor plate 4 to be fixed to the lower end 43b of the chamfered portion 43, the floor plate fixture 1 with respect to the support material 5 is provided. A countersunk screw having a head 71 having a diameter r larger than the joint width W2 by using a countersunk screw having a head 71 having a diameter r smaller than the width between the upper ends 43a of the chamfered portions 43 adjacent to the fixing portion 43. As a result, the occurrence of problems such as breakage of the tool fitting recess formed in the head of the screw nail 7 can be reduced.

また，このように頭部の直径ｒが目地幅Ｗ2に対して大きな螺子釘７を使用した場合であっても，螺子釘７の頭部７１を隣接する面取り部４３，４３間の間隔に嵌合させることができ，螺子釘７の頭部７１が床板４の側面４０を削ることなく，且つ，床板４の表面より突出させることなく取り付けることができた。 Further, even when the screw nail 7 having the head diameter r larger than the joint width W2 is used, the head 71 of the screw nail 7 is fitted in the space between the adjacent chamfered portions 43, 43. The head 71 of the screw nail 7 could be attached without cutting the side surface 40 of the floor plate 4 and without protruding from the surface of the floor plate 4.

しかも，螺子釘７の頭部７１の傾斜側面７１ａが面取り部４３と接触することにより，床板４との接触抵抗を更に増大させて，通常の使用状態において床板４が移動することを更に確実に防止することができた。 In addition, when the inclined side surface 71a of the head 71 of the screw nail 7 is in contact with the chamfered portion 43, the contact resistance with the floor plate 4 is further increased, and the floor plate 4 is more reliably moved in a normal use state. Could be prevented.

〔床板固定具の構成〕
本発明の床板固定具１は，架橋片３と，前記架橋片３の幅方向における中間位置より前記床板の表裏面方向に突出するスペーサ片２を，可撓性を有する合成樹脂材料，例えばＡＢＳ樹脂，ポリプロピレン，ポリエチレン，塩化ビニル，ナイロンの他，ガラス繊維強化ポリプロピレン：(ガラス繊維長) 0.5〜5mm ; (ガラス繊維含有率)10〜40重量部等の適度な剛性と可撓性とを兼ね備えた合成樹脂材料により一体的に形成して，断面十字状に形成したものである〔図１（Ｂ）参照〕。 [Configuration of floor plate fixture]
The floorboard fixture 1 of the present invention has a bridge piece 3 and a spacer piece 2 projecting in the front and back direction of the floor board from an intermediate position in the width direction of the bridge piece 3 with a flexible synthetic resin material such as ABS. Resin, polypropylene, polyethylene, vinyl chloride, nylon, glass fiber reinforced polypropylene: (glass fiber length) 0.5 to 5 mm; (glass fiber content) 10-40 parts by weight, etc. The synthetic resin material is integrally formed to have a cross-shaped cross section (see FIG. 1B).

そして，前述のスペーサ片２には，該スペーサ片２を前記突出方向に貫通する釘孔２１が設けられており，隣接配置された床板４の対向する側面４０にそれぞれ形成されたスリット４１に前記架橋片３を挿入すると共に，スペーサ片２を床板４の側面４０間に挟持して床板が一定の目地幅Ｗ2となるように配置した状態で釘孔２１に挿入した螺子釘７を支持材５に打ち込む（ねじ込む）ことにより，床板固定具１が根太等の支持材５に固定されると共に，この床板固定具１を介して床板４が支持材５上に取り付けられる〔図５（Ａ），（Ｂ）参照〕。 The spacer piece 2 is provided with a nail hole 21 penetrating the spacer piece 2 in the protruding direction, and the slit 41 formed in each of the opposing side surfaces 40 of the floor plate 4 arranged adjacent to the spacer piece 2 While inserting the bridging piece 3 and holding the spacer piece 2 between the side surfaces 40 of the floor plate 4 so that the floor plate has a constant joint width W2, the screw nail 7 inserted into the nail hole 21 is supported by the support member 5. The floor board fixture 1 is fixed to the support material 5 such as joists, and the floor board 4 is attached to the support material 5 via the floor board fixture 1 (FIG. 5A). (See (B)).

床板４の側面４０に挟持接触される床板固定具１のスペーサ片２の側面２３には，スペーサ片２の前記床板側面４０の長さ方向に直交する方向に，所定間隔で列条を成す複数の凸条２２が形成されており，図１に示す実施形態にあっては，スペーサ片２の一方の側面２３（２３ａ，２３ｂ；２３ｃ，２３ｄ）に，それぞれ５本の凸条２２を形成している。 On the side surface 23 of the spacer piece 2 of the floor plate fixture 1 that is sandwiched and brought into contact with the side surface 40 of the floor plate 4, a plurality of lines are formed at predetermined intervals in a direction orthogonal to the length direction of the floor plate side surface 40 of the spacer piece 2. In the embodiment shown in FIG. 1, five ridges 22 are formed on one side surface 23 (23a, 23b; 23c, 23d) of the spacer piece 2, respectively. ing.

この凸条２２は，スペーサ片２の側面２３のうち，床板４の側面４０と接触する全ての部分に対して形成しても良く（図１参照），又はそのうちの一部，例えば側面２３のうち架橋片３の下側に位置する部分（２３ｂ，２３ｄ）の一方のみ（図２参照）又は双方に形成しても良く，更には側面２３のうち架橋片３の上側に位置する部分２３ａ，２３ｃの一方又は双方に形成しても良く，更には，これらの任意の組合せとなる側面に形成するものとしても良い。 The ridges 22 may be formed on all portions of the side surface 23 of the spacer piece 2 that are in contact with the side surface 40 of the floor plate 4 (see FIG. 1), or a part thereof, for example, the side surface 23. Of these, it may be formed on only one (see FIG. 2) or both of the portions (23b, 23d) located on the lower side of the bridging piece 3, and further, on the side surface 23, the portion 23a located on the upper side of the bridging piece 3. It may be formed on one or both of 23c, and further, it may be formed on a side surface of any combination thereof.

なお，スペーサ片２の側面２３の一部に凸条２２を設ける場合，床板４の側面４０間にこのスペーサ片２を挟持した際に，凸条２２が形成された側面にあっては凸条２２の頂部が，凸条２２の形成されていない側面では，側面の平坦面がいずれも床板４の側面４０と接触することとなるように各部のサイズを調整する。 In the case where the ridge 22 is provided on a part of the side surface 23 of the spacer piece 2, when the spacer piece 2 is sandwiched between the side surfaces 40 of the floor plate 4, the ridge 22 is formed on the side surface on which the ridge 22 is formed. The size of each part is adjusted so that the flat part of the side surface is in contact with the side surface 40 of the floor plate 4 at the side surface where the top of 22 is not formed with the ridges 22.

この凸条２２は，図１に示す実施形態にあっては，平面視において頂部２２ａが平坦に形成された比較的幅広の矩形状の凸条となっているが〔図１（Ｃ）参照〕，この凸条２２は，より幅狭の凸条２２を図１の構成に比較して多数設けるものとしても良く，また，図２に示すように，平面視において頂部２２ａが尖鋭状の三角形状の凸条２２を設けてスペーサ片２の側面が全体として鋸歯状となるようにしても良く，更には図３に示すように，比較的幅広に形成された凸条２２の頂部に，更に細かい凸条２２’，図示の例では頂部が尖鋭状の凸条２２’を形成するようにしても良く，スペーサ片２の床板４の長手方向と直交方向を成し，床板４の側面４０との接触抵抗を増大させ得るものであれば，各種形状として形成することができる。 In the embodiment shown in FIG. 1, the ridge 22 is a relatively wide rectangular ridge having a flat top portion 22a in plan view [see FIG. 1 (C)]. The protrusions 22 may be provided with a larger number of narrower protrusions 22 as compared to the configuration of FIG. 1, and as shown in FIG. 2, the top 22a has a sharp triangular shape in plan view. The side surface of the spacer piece 2 may be formed in a sawtooth shape as a whole. Further, as shown in FIG. 3, a finer shape is formed on the top of the relatively wide ridge 22. Convex ridges 22 ′, in the example shown in the figure, may be formed with ridges 22 ′ having a sharp top, which forms a direction orthogonal to the longitudinal direction of the floor plate 4 of the spacer piece 2, and the side surface 40 of the floor plate 4. Any shape that can increase the contact resistance can be formed.

このような接触抵抗の増大という観点からは，凸条２２は，図２及び図３に示すように，平面視において頂部が尖鋭状の凸条２２，２２’を設け，これによりスペーサ片２の側面を鋸歯状に形成することが好ましい。 From the viewpoint of increasing the contact resistance, the ridge 22 is provided with ridges 22 and 22 ′ having a sharp top in plan view, as shown in FIGS. The side surface is preferably formed in a sawtooth shape.

また，このようにスペーサ片２の側面に設ける凸条２２の頂部２２ａを鋭状に形成して鋸歯状とする場合には，図２（Ｄ）中に拡大図で示すように，凸条２２の裾から頂部２２ａに至る２辺を不等辺に形成する等して，凸条２２の頂部２２ａを，凸条２２の幅方向における一方側に偏って設けるように形成するものとしても良い。 Further, in the case of a serrated to form the top 22a of the projections 22 provided in this manner on the side surface of the spacer piece 2 sharp shape, as shown in the enlarged view in FIG. 2 (D), the projections 22 The top 22a of the ridge 22 may be formed so as to be biased to one side in the width direction of the ridge 22 by, for example, forming two sides from the hem to the top 22a as unequal sides.

このスペーサ片２には，このスペーサ片２を前記突出方向に貫通する釘孔２１が設けられている。 The spacer piece 2 is provided with a nail hole 21 that penetrates the spacer piece 2 in the protruding direction.

この釘孔２１は，図１の実施形態にあっては上端部分が上向きに広がるテーパ状に形成されている一方，他の部分を全て同一径に形成し〔図１（Ｂ）参照〕，後述する螺子釘７として皿螺子を使用すると，この皿螺子の頭部７１に形成された傾斜側面７１ａが，テーパ状に形成された釘孔２１の上端部分に一部入り込むようになっている。 In the embodiment of FIG. 1, the nail hole 21 is formed in a tapered shape with the upper end portion extending upward, while all other portions are formed to have the same diameter (see FIG. 1B), which will be described later. When a countersunk screw is used as the screw nail 7, the inclined side surface 71a formed on the head 71 of the countersunk screw partially enters the upper end portion of the tapered nail hole 21.

スペーサ片２は，好ましくは後述する架橋片３の下端から釘孔２１の形成位置におけるスペーサ片２の上端迄の高さｈ〔図１（Ａ），（Ｂ）参照〕が，固定対象とする床板４のスリット４１に設けられた床板の裏面側内壁４１ａから床板表面における幅方向両端に形成された面取り部４３の下端４３ｂ位置迄の高さＨ〔図５（Ａ）参照〕と略同一の高さとなるように形成することが好ましい。 The spacer piece 2 preferably has a height h [see FIGS. 1 (A) and 1 (B)] from the lower end of the bridge piece 3 to be described later to the upper end of the spacer piece 2 at the position where the nail hole 21 is formed. Almost the same height H from the back side inner wall 41a of the floor plate provided in the slit 41 of the floor plate 4 to the position of the lower end 43b of the chamfered portion 43 formed at both ends in the width direction on the floor plate surface (see FIG. 5A). It is preferable to form so that it may become height.

このように形成することで，面取り部４３の上端４３ａ間の幅Ｗ3〔図５（Ｂ）参照〕よりも直径が小さいものであれば，床板４の側面４０間の間隔である目地幅Ｗ2よりも直径ｒの大きな頭部７１を有する螺子釘７を使用して床板固定具１を固定することができ，これにより螺子釘７の頭部に形成された工具嵌合用の窪みが皿螺子の締め込み中に破損し難くすることができると共に，このような螺子釘７を使用した場合であっても，螺子釘７の頭部７１を面取り部４３間の間隔に嵌合させて，床板の表面より突出しないように施工することができる。 By forming in this way, if the diameter is smaller than the width W3 between the upper ends 43a of the chamfered portion 43 (see FIG. 5B), the joint width W2 which is the interval between the side surfaces 40 of the floor board 4 is obtained. The floor plate fixture 1 can be fixed using a screw nail 7 having a head 71 having a large diameter r, and a recess for fitting a tool formed in the head of the screw nail 7 is tightened with a countersunk screw. Even when such a screw nail 7 is used, the head 71 of the screw nail 7 is fitted in the space between the chamfered portions 43 so that the surface of the floor board can be obtained. It can be constructed so as not to protrude further.

しかも，螺子釘７の頭部７１に形成された傾斜側面７１ａが床板４の面取り部４３と接触した状態で取り付けられるために〔図５（Ｂ）参照〕，螺子釘７の傾斜側面７１ａと床板４との接触により，螺子釘７を介して床板４と床板固定具１との接触抵抗を更に増大させることができる。 Moreover, since the inclined side surface 71a formed on the head 71 of the screw nail 7 is attached in contact with the chamfered portion 43 of the floor plate 4 (see FIG. 5B), the inclined side surface 71a of the screw nail 7 and the floor plate are attached. 4, the contact resistance between the floor plate 4 and the floor plate fixture 1 can be further increased via the screw nails 7.

なお，図１に示す実施形態にあっては，図１（Ａ）の正面図に示すようにスペーサ片２の上端を中央において高く，幅方向の両端において低くなるように形成し，全体として中央が膨出する丸みを帯びた形状に形成しているが，床板固定具１の形状はこれに限定されず，スペーサ片２の上端をいずれの位置においても均一な高さに形成するものとしても良く，又は，中央部分において高く，幅方向の両端において低い，例えば台形状に形成するものとしても良く，更には，図１（Ｂ）における釘孔の上端テーパ部に対応する部分の全部又は一部を切り欠いて，図２（Ａ）に示すように中央部が窪んだ形状に形成しても良い。 In the embodiment shown in FIG. 1, as shown in the front view of FIG. 1A, the upper end of the spacer piece 2 is formed so as to be high at the center and low at both ends in the width direction. However, the shape of the floor plate fixture 1 is not limited to this, and the upper end of the spacer piece 2 may be formed at a uniform height at any position. Alternatively, it may be formed in a trapezoidal shape that is high at the central portion and low at both ends in the width direction, and further, all or one of the portions corresponding to the upper tapered portion of the nail hole in FIG. You may cut out a part and form it in the shape where the center part was depressed, as shown to FIG. 2 (A).

また，スペーサ片２の幅方向における両端には，一例として図４に示すように，スペーサ片２の端縁から外向きに広がるＶ字状の変形部２４を設けるものとしても良い。 Further, as shown in FIG. 4 as an example, V-shaped deformed portions 24 that spread outward from the edge of the spacer piece 2 may be provided at both ends in the width direction of the spacer piece 2.

この変形部２４は，床板固定具１の取付前の状態では，最大幅がスペーサ片２の肉厚よりも幅広に形成されているものであっても良いが，取付時には変形して，床板４の側面４０が，スペーサ片２の側面との挟持接触を規制しない程度の変形性を有するように形成されている。 The deformed portion 24 may be formed with a maximum width wider than the thickness of the spacer piece 2 before the floor plate fixture 1 is attached, but it is deformed at the time of attachment, and the floor plate 4 The side surface 40 is formed so as to be deformable to the extent that the clamping contact with the side surface of the spacer piece 2 is not restricted.

以上のように形成されたスペーサ片２は，平面視において略長方形に形成された架橋片３の幅方向における中央においてこの架橋片３と交わっており，床板固定具１が全体として図１（Ｂ）に示した側面断面図に表れているように十字状に形成されている。 The spacer piece 2 formed as described above intersects with the bridging piece 3 at the center in the width direction of the bridging piece 3 formed in a substantially rectangular shape in plan view, and the floor plate fixture 1 as a whole is shown in FIG. It is formed in a cross shape as shown in the side sectional view shown in FIG.

この架橋片３は，床板４の側面４０に形成されたスリット４１に挿入可能なものであれば，全体が一定の厚みとなるように図２に示すように平坦な形状に形成するものとしても良く，又は，図１に示すように周縁部にリブを備えた形状としても良く，更には，前述したスペーサ片と同様の凸条を架橋片３の床板４との接触する部分に設けるものとしても良い。 As long as this bridge | crosslinking piece 3 can be inserted in the slit 41 formed in the side surface 40 of the floor board 4, it may be formed in flat shape as shown in FIG. 2 so that the whole may become constant thickness. Alternatively, as shown in FIG. 1, it may have a shape with ribs at the peripheral edge, and furthermore, a protrusion similar to the spacer piece described above is provided on the portion of the bridging piece 3 that contacts the floor plate 4. Also good.

スペーサ片２の下端から架橋片３の下端迄の高さｌ〔図１（Ａ），（Ｂ）参照〕は，固定対象とする床板４の裏面からスリット４１の床板裏面側内壁４１ａ迄の高さＬ〔図５（Ａ）参照〕と同一，好ましくは，これよりも若干低く形成することが好ましい。 The height l from the lower end of the spacer piece 2 to the lower end of the bridging piece 3 (see FIGS. 1A and 1B) is the height from the back surface of the floor plate 4 to be fixed to the inner surface 41a of the floor plate rear surface side of the slit 41. It is preferable that the length L is the same as that of L (see FIG. 5A), preferably slightly lower.

なお，架橋片３の最大厚さ，図１の実施形態では架橋片３の周縁部の厚さは，床板４の側面４０に形成されたスリット４１の幅と同一幅に形成して，架橋片３がスリット４１内に圧嵌されるようにしても良く，又はスリット４１の幅に対して薄く形成して，スリット４１内に遊嵌されるように構成しても良い。 The maximum thickness of the bridging piece 3, in the embodiment of FIG. 1, the thickness of the peripheral edge of the bridging piece 3 is formed to be the same width as the width of the slit 41 formed on the side surface 40 of the floor plate 4. 3 may be press-fitted in the slit 41, or may be formed thinly with respect to the width of the slit 41 so as to be loosely fitted in the slit 41.

なお，架橋片３は，床板４の側面４０間でスペーサ片２を挟持した際に，スリット４１の最奥部に存在する内壁と干渉しないサイズに形成する。 The bridging piece 3 is formed in a size that does not interfere with the inner wall present at the innermost part of the slit 41 when the spacer piece 2 is sandwiched between the side surfaces 40 of the floor plate 4.

以上のように形成された床板固定具１は，螺子釘７を使用して支持材５に固定され，好ましくはこの螺子釘７として皿螺子を使用して支持材５に固定される。 The floor board fixture 1 formed as described above is fixed to the support member 5 using a screw nail 7, and is preferably fixed to the support member 5 using a countersunk screw as the screw nail 7.

この床板固定具１の固定に使用する螺子釘７は，支持材５に対する打ち込み深さを確保することができるようスペーサ片２の全高に対して長く形成されていると共に，頭部７１以外の部分を，スペーサ片２に形成された釘孔２１に挿入することができる太さに形成されている。 The screw nail 7 used for fixing the floor plate fixing tool 1 is formed long with respect to the total height of the spacer piece 2 so as to secure a driving depth with respect to the support member 5 and a portion other than the head 71. Is formed in a thickness that can be inserted into a nail hole 21 formed in the spacer piece 2.

〔使用方法及び作用〕
以上のように構成された本発明の床板固定具１は，図５（Ａ），（Ｂ）に示すように，隣接配置する床板４の対向する側面４０にそれぞれ形成されたスリット４１内に架橋片３を挿入すると共に，床板４の側面４０がスペーサ片２の側面２３と接触するように，床板４の側面４０間でスペーサ片２を挟持する。 [Usage and action]
As shown in FIGS. 5A and 5B, the floor board fixture 1 of the present invention configured as described above is bridged in the slits 41 respectively formed on the opposite side surfaces 40 of the adjacent floor boards 4. While inserting the piece 3, the spacer piece 2 is sandwiched between the side surfaces 40 of the floor plate 4 so that the side surface 40 of the floor plate 4 contacts the side surface 23 of the spacer piece 2.

床板固定具１が図４に示す変形部２４を有する場合には，この変形部２４の変形により床板４の側面４０がスペーサ片２の側面２３に対して押圧接触されるように床板４間の間隔を調整する。 When the floor plate fixture 1 has the deformed portion 24 shown in FIG. 4, the deformation of the deformed portion 24 causes the side surface 40 of the floor plate 4 to be pressed against the side surface 23 of the spacer piece 2. Adjust the interval.

この作業により，床板４間に形成される目地幅Ｗ2が，スペーサ片２の肉厚によって一定幅に位置決めされ，目地幅Ｗ2が揃った美しい状態で床板４を敷設することができる。 By this operation, the joint width W2 formed between the floor boards 4 is positioned at a constant width by the thickness of the spacer piece 2, and the floor board 4 can be laid in a beautiful state where the joint widths W2 are aligned.

この状態で釘孔２１内に挿入した螺子釘７を支持材５に打ち込んでいくと，スペーサ片２の下端が支持材５上に押圧されると共に，架橋片３の裏面がスリット４１の裏面側内壁４１ａ上に押圧され，これにより床板４は，床板固定具１を介して支持材５上に固定される。 When the screw nail 7 inserted into the nail hole 21 is driven into the support member 5 in this state, the lower end of the spacer piece 2 is pressed onto the support member 5 and the back surface of the bridging piece 3 is the back side of the slit 41. The floor plate 4 is pressed onto the inner wall 41 a, whereby the floor plate 4 is fixed on the support member 5 via the floor plate fixture 1.

このようにして床板４を，根太等の支持材５の配置間隔に対応して床板４の長手方向に所定間隔，一例として４５０mm程度の間隔で複数箇所固定する。 In this way, the floor plate 4 is fixed at a plurality of locations in the longitudinal direction of the floor plate 4 at a predetermined interval, for example, an interval of about 450 mm, corresponding to the arrangement interval of the support members 5 such as joists.

床板固定具１は，床板４に対して釘や螺子釘，接着剤等によって直接固定せず，前述した架橋片３の裏面とスリット４１の床板裏面側内壁４１ａとの押圧接触と，床板４の側面４０とスペーサ片２の側面との押圧接触によって床板を固定した状態となっているが，前述した床板固定具１の構造により，従来技術として説明したＴ字状の固定具〔図９（Ｂ）参照〕に比較して，スペーサ片２が架橋片３の上方にも存在することにより，床板４の側面４０と床板固定具１との接触面積の増大が得られ，これにより接触抵抗の増大が得られるものとなっている。 The floor plate fixture 1 is not directly fixed to the floor plate 4 with a nail, a screw nail, an adhesive, or the like, but the pressing contact between the back surface of the bridge piece 3 and the inner surface 41a of the floor plate back surface side of the slit 41 and the floor plate 4 Although the floor plate is fixed by pressing contact between the side surface 40 and the side surface of the spacer piece 2, the structure of the floor plate fixture 1 described above allows the T-shaped fixture described in the prior art [FIG. Compared to the above), the presence of the spacer piece 2 also above the bridge piece 3 increases the contact area between the side surface 40 of the floor board 4 and the floor board fixture 1, thereby increasing the contact resistance. Is obtained.

しかも，スペーサ片２の側面２３には，図５の実施形態において，該スペーサ片の上下方向を長さ方向とする凸条，従って，前記床板４の側面のスリット長手方向に対して直交方向を成す凸条２２が形成されているために，スペーサ片２の側面２３と床板４の側面４０との接触抵抗も増大している。 In addition, in the embodiment of FIG. 5, the side surface 23 of the spacer piece 2 is provided with a ridge having a length direction in the vertical direction of the spacer piece, and thus a direction orthogonal to the slit longitudinal direction of the side surface of the floor plate 4. Since the protruding ridges 22 are formed, the contact resistance between the side surface 23 of the spacer piece 2 and the side surface 40 of the floor plate 4 is also increased.

更に，床板固定具１の固定に，前述したように目地幅Ｗ2よりも大径の頭部７１を有する皿螺子７を使用する場合には，この皿螺子７を締め込んでいくと皿螺子の頭部７１に設けられた傾斜側面７１ａが床板４の上端角部に形成された面取り部４３に接触・押圧されることとなるために，この皿螺子の頭部７１における傾斜側面７１ａと床板４との接触抵抗によっても床板４の移動が規制されている。 Further, when the countersunk screw 7 having the head 71 having a diameter larger than the joint width W2 is used for fixing the floor plate fixture 1, as shown in FIG. Since the inclined side surface 71a provided on the head 71 comes into contact with and is pressed by the chamfered portion 43 formed at the upper corner of the floor plate 4, the inclined side surface 71a and the floor plate 4 of the head 71 of the countersunk screw are used. The movement of the floor plate 4 is also restricted by the contact resistance.

更に，スペーサ片２の幅方向における両端に，Ｖ字状の変形部２４を設けた構成にあっては，この変形部２４が弾性復帰しようとする力によって床板４の側面４０に押圧されていると共に，床板４が長手方向に移動しようとした際に，床板と共にその先端部が移動しようとするために，いずれか一方の変形部２４が外向きに広がろうとするために，床板４の側面４０に対する接触抵抗が更に増大する。 Further, in the configuration in which the V-shaped deformed portions 24 are provided at both ends in the width direction of the spacer piece 2, the deformed portions 24 are pressed against the side surface 40 of the floor plate 4 by a force for elastic recovery. At the same time, when the floor plate 4 is about to move in the longitudinal direction, the tip portion of the floor plate is about to move together with the floor plate, so that any one of the deformed portions 24 tends to spread outward. The contact resistance to 40 is further increased.

そのため，床板４と床板固定具１との接触状態は，床板４上を人が歩行等した場合のように，通常の使用状態で加わる力に対しては，床板４が移動しないように固定するに十分な力を発生する。 Therefore, the contact state between the floor board 4 and the floor board fixture 1 is fixed so that the floor board 4 does not move against the force applied in the normal use state, such as when a person walks on the floor board 4. Sufficient power to generate.

一方，例えば床板４が気温や湿度の変化に伴って膨張，収縮することにより，床板４の寸法自体が変化して，床板固定具１との接触位置を移動させようとする極めて強い力が生じた場合には，床板４と床板固定具１とは前述したように釘や螺子釘，接着剤等による直接的に固着は行われていないために，床板４の移動を許容し得るものとなっている。 On the other hand, for example, when the floor board 4 expands and contracts with changes in temperature and humidity, the dimension of the floor board 4 itself changes, and an extremely strong force is generated to move the contact position with the floor board fixture 1. In this case, since the floor plate 4 and the floor plate fixture 1 are not directly fixed by a nail, a screw nail, an adhesive or the like as described above, the floor plate 4 can be allowed to move. ing.

その結果，床板４のこのような膨張，収縮に伴う寸法変化が生じても，床板固定具１が破損し，床板固定具１を支持材５に固定する螺子釘７が外れ，更には，床板４に反りや歪み等の変形が生じることを好適に防止することができる。 As a result, even if the dimensional change accompanying the expansion and contraction of the floor board 4 occurs, the floor board fixing tool 1 is damaged, the screw nail 7 that fixes the floor board fixing tool 1 to the support member 5 is removed, and further, the floor board 4 can be suitably prevented from being deformed such as warpage or distortion.

なお，図２に示したように，尖鋭状頂部２２ａを凸条２２の幅方向のいずれか一方寄りに偏って配置した凸条２２を備える床板固定具１にあっては，この床板固定具１の凸条２２が床板４の側面に対して図６（Ａ），（Ｂ）に示すように接触しているものとすると，この床板固定具１が床板４の移動を規制しようとする力は，図６（Ｂ）に矢印Ｂ方向に移動しようとする床板４を規制する場合に比較して，図６（Ａ）に記載した矢印Ａ方向に移動しようとする床板４を規制する力の方が強くなる。 In addition, as shown in FIG. 2, in the floor board fixture 1 provided with the ridges 22 in which the sharp top portions 22a are arranged so as to be biased toward either one of the width directions of the ridges 22, this floor board fixture 1 As shown in FIGS. 6 (A) and 6 (B), the force that the floor plate fixture 1 tries to regulate the movement of the floor plate 4 is as follows. 6B, the force that regulates the floor plate 4 that is going to move in the direction of arrow A shown in FIG. 6A is compared with the case where the floor plate 4 that is going to move in the direction of arrow B is restricted in FIG. Becomes stronger.

すなわち，上記の例において，図６（Ａ）に示すように床板４が図中矢印Ａの方向に移動する場合，可撓性材料によって形成された床板固定具１の凸条２２は，頂部２２ａが床板４の移動に引かれて図中矢印ａに示すように，外向きに広がるように変形する。その結果，この凸条２２の変形によって床板４の側面４０との接触抵抗は増大する。 That is, in the above example, when the floor plate 4 moves in the direction of the arrow A in the figure as shown in FIG. 6A, the ridge 22 of the floor plate fixture 1 formed of a flexible material is the top portion 22a. Is pulled by the movement of the floor plate 4 and deforms so as to spread outward as indicated by an arrow a in the figure. As a result, the contact resistance with the side surface 40 of the floor board 4 increases due to the deformation of the ridges 22.

一方，図６（Ｂ）に示すように，床板４が図中矢印Ｂ方向に移動する場合，可撓性材料によって形成された床板固定具１の凸条２２は，頂部２２ａが床板４の移動に引かれて図中矢印ｂに示すように，内向きに狭まるように変形する。その結果，上記形状の凸条２２を設ける場合，床板固定具１は，矢印Ｂ方向へ移動しようとする床板４に対し，矢印Ａ方向に移動しようとする床板４の移動をより強固に規制する。 On the other hand, as shown in FIG. 6 (B), when the floor plate 4 moves in the direction of arrow B in the figure, the protrusion 22 of the floor plate fixture 1 made of a flexible material has a top portion 22a that moves the floor plate 4. As shown by the arrow b in the figure, it is deformed so as to narrow inward. As a result, when the protruding strip 22 having the above-described shape is provided, the floor plate fixture 1 more firmly regulates the movement of the floor plate 4 attempting to move in the arrow A direction relative to the floor plate 4 attempting to move in the arrow B direction. .

以上のように，図２に示した床板固定具１にあっては，向きによって床板４の移動に対する規制力が異なることから，例えば図６（Ｃ）に示すように床板４の長手方向における所定間隔毎に，床板固定具１（１ａ〜１ｄ）を，例えば交互に逆向きとなるように配置して，床板４が図６（Ａ）中矢印Ａ方向に移動しようとしたときには，床板固定具１ａ，１ｃにより，逆に図６（Ｂ）中の矢印Ｂ方向に移動しようとした場合には床板固定具１ｂ，１ｄにより強固に移動を規制する作用を発揮させて，床板４が長手方向のいずれの方向に対しても移動しないようにしても良い。 As described above, in the floor board fixture 1 shown in FIG. 2, the restriction force for the movement of the floor board 4 varies depending on the orientation. For example, as shown in FIG. For example, when the floorboard fixtures 1 (1a to 1d) are alternately arranged in the opposite directions and the floorboard 4 is about to move in the direction of arrow A in FIG. On the contrary, when trying to move in the direction of arrow B in FIG. 6 (B) by 1a, 1c, the floor plate fixing tool 1b, 1d exerts the action of firmly restricting the movement so that the floor plate 4 is in the longitudinal direction. It may not be moved in any direction.

また，例えば図６（Ｄ）に示すように，床板４の長手方向の一端を横木等に突合させてその移動を規制した状態で，この横木から離間する方向への床板４の移動に対する規制力が大きくなるように床板固定具１（１ａ，１ｂ）を取り付けるようにしても良く，このように構成する場合には，床板４の一端が常に横木に突合した状態に維持される。 In addition, for example, as shown in FIG. 6 (D), in the state where the longitudinal end of the floor board 4 is abutted against a rung etc. and its movement is regulated, the regulation force for the movement of the floor board 4 in the direction away from the rung The floor plate fixture 1 (1a, 1b) may be attached so as to be large. In such a configuration, one end of the floor plate 4 is always maintained in a state where it abuts against the rung.

なお，図６（Ｄ）に示したように床板４及び床板固定具１（１ａ，１ｂ）を取り付ける場合には，予期せざる大きな力が床板４に加わる等して万が一にも床板４が横木より離間する方向に移動してしまった場合であっても，床板４を，一端を横木に突合させた原位置に自動的に復帰させることができる。

When the floor board 4 and the floor board fixture 1 (1a, 1b) are attached as shown in FIG. 6 (D), an unexpected large force is applied to the floor board 4. Even if it has moved in a more separated direction, the floor board 4 can be automatically returned to the original position with one end abutted against the cross.

すなわち，図６（Ｅ）に示すように，一端が横木から離間した状態にある床板４が膨張して寸法を増大するように変形した場合，床板固定具１ｂに対して床板固定具１ａの方が移動を規制する力が弱い。そのため，床板４は図６（Ｅ）中に破線で示すように横木側の端部を横木に近付けるように膨張する。 That is, as shown in FIG. 6 (E), when the floor plate 4 with one end spaced apart from the cross is expanded and deformed so as to increase in size, the floor plate fixing tool 1a is more deformed than the floor plate fixing tool 1b. However, its ability to regulate movement is weak. Therefore, the floor board 4 expand | swells so that the edge part of a crosspiece side may approach a crosspiece as shown with a broken line in FIG.6 (E).

一方，床板４が収縮して寸法を減少する場合には，床板固定具１ａに比較して床板固定具１ｂの規制力が弱いために，床板は，同図中右側の端部を縮めるように変形する結果，床板４の膨張，収縮に伴って床板４が自ら横木と突合した原位置（施工時の位置）に自動で復帰させることもできる。 On the other hand, when the floor board 4 is contracted to reduce the size, the floor board is contracted at the right end in the figure because the regulation force of the floor board fixture 1b is weaker than that of the floor board fixture 1a. As a result of the deformation, the floor plate 4 can be automatically returned to the original position (position at the time of construction) where the floor plate 4 abuts the rung as the floor plate 4 expands and contracts.
