Description

本発明は、折板タイプの金属屋根(又は壁)の施工において、屋根板材(壁板材)をタイトフレームに装着するための吊子をタイトフレームにボルト・ナットにて固着する作業で、ナット等の部品を落下させることを防止でき、タイトフレームへの吊子取付の作業効率を向上させることができる建築用金具に関する。   The present invention, in the construction of a folding plate type metal roof (or wall), in the work of fixing the suspension for mounting the roof plate material (wall plate material) to the tight frame to the tight frame with bolts and nuts, such as nuts The present invention relates to a building metal fitting that can prevent falling of parts of the above and can improve the work efficiency of attaching the suspension to the tight frame.

従来、折板タイプの金属製の屋根(又は壁)を施工するために、H型又はI(アイ)型等の型鋼を利用した母屋,胴縁等の構造材にタイトフレーム(受具とも言う)に吊子を取り付けるための方法として、一般的にボルト・ナット等の固着具にて取り付ける方法が多く用いられている。これは、近年、工事現場における溶接工法は、火災等の原因となるため、種々の部品の固着手段として、ボルト・ナットの使用が多くなる傾向にあることでも明らかである。   Conventionally, in order to construct a folding plate type metal roof (or wall), a tight frame (also called a receiver) is used for structural materials such as purlins and furrings that use shaped steel such as H type or I (eye) type. As a method for attaching the hanger to the), generally, a method of attaching with fasteners such as bolts and nuts is often used. This is also apparent from the fact that in recent years, the welding method at a construction site causes a fire or the like, so that the use of bolts and nuts tends to increase as a means for fixing various parts.

特開平11−229564号公報JP-A-11-229564

タイトフレームに吊子を取り付ける場合において、ボルト・ナット等の固着具を使用するものとして、多くの実例が存在するが、ここでは、特許文献1(特開平11−229564号公報)を挙げてみた。特に、引用文献1における図2,図23,図24には、タイトフレームに吊子がボルト・ナットで取り付けられた状態が開示されている。ところで、折板屋根の施工におけるタイトフレームの個数は、施工する屋根の面積が大きくなるほど、その数も多くなり、大型施設の屋根の施工では、大量のタイトフレームと、これと同数の吊子を揃えなければならない。   There are many actual examples of using fasteners such as bolts and nuts when attaching a suspension to a tight frame, but here, Patent Document 1 (JP-A-11-229564) is cited. . In particular, FIG. 2, FIG. 23, and FIG. 24 in the cited document 1 disclose a state in which the suspension is attached to the tight frame with bolts and nuts. By the way, the number of tight frames in the construction of a folded plate roof increases as the area of the roof to be constructed increases. Must be aligned.

そして、前述したように、タイトフレームと吊子との接合に使用されるボルト・ナットの個数も大量となる。このような大量のボルト・ナットを揃えると、これらのボルト・ナットにてタイトフレームに吊子を固着する場合、その作業中にナット等の部品を落下させてしまうおそれは十分にある。特に、高層建築物の工事現場では、たとえ、ナット等の小部品であっても、落下すると極めて危険な事態が発生することになる。   Further, as described above, the number of bolts and nuts used for joining the tight frame and the suspension is also large. When a large number of such bolts and nuts are aligned, there is a sufficient risk that parts such as nuts may drop during the work when the suspension is fixed to the tight frame with these bolts and nuts. In particular, at a construction site of a high-rise building, even if a small part such as a nut is dropped, an extremely dangerous situation will occur.

以下、従来の工程を図9に基づいて説明する。まず、ナット等の部品bの落下は、吊子dをタイトフレームaに装着する際に生じやすいものであり、その原因として、作業員は一方の手でボルトcを持ち、他方の手でナット等の部品bを持ちながら、両者を螺合させ、さらに工具にてボルトcを締め付けるという作業環境にある〔図9(A)参照〕。このような、両手に別々の部品を持つ場合には、作業員は、うっかりしてナット等の部品bを落としてしまう危険性は十分にある。   The conventional process will be described below with reference to FIG. First, a component b such as a nut is likely to fall when the suspension d is attached to the tight frame a. The cause is that the worker holds the bolt c with one hand and the nut with the other hand. The work environment is such that while holding the component b, etc., both are screwed together and the bolt c is tightened with a tool [see FIG. 9 (A)]. In the case of having separate parts in both hands as described above, there is a sufficient risk that the worker may inadvertently drop the part b such as the nut.

また、タイトフレームaにナットbを予め溶接にて固着しておくことも、1つの案として採用できるが、その溶接状態が不十分であったり、不良であると、現場でタイトフレームaに固着されていたナットが、何らかの外的要因による衝撃で、外れて落下することが十分に有り得るものである〔図9(B)参照〕。   Further, fixing the nut b to the tight frame a by welding in advance can also be adopted as one proposal, but if the welding state is insufficient or defective, the nut is fixed to the tight frame a on site. It is quite possible that the existing nut may fall off due to an impact due to some external factor [see FIG. 9 (B)].

そこで、本発明の目的(解決しようとする技術的課題)は、折板タイプの金属屋根(又は壁)の施工において、タイトフレームに屋根板材(又は壁板材)を設置するための介在物である吊子等の固着をボルト・ナットにて行う際に、ナットが作業員のうっかりミス等にて落下することを未然に防ぐことができる構成部品を提供することにある。   Therefore, an object of the present invention (technical problem to be solved) is an inclusion for installing a roof plate material (or wall plate material) on a tight frame in the construction of a folded plate type metal roof (or wall). An object of the present invention is to provide a component that can prevent the nut from falling due to an accidental mistake of an operator when fixing the suspension and the like with a bolt and a nut.

内螺子部3は、内周に内螺子が形成された部位である。該内螺子は、ボルト8と螺合する部位である。内螺子部3には貫通孔の内周に内螺子3aが形成された部位である(図3参照)。内螺子部3として、具体的には、内螺子3aがもうけられたナット31を使用することが多い。内螺子部3としてナット31が使用された場合には、下板部12の表面(上面)側に固着される(図3参照)。その固着手段は、溶接wが使用されることが多い(図3参照)。   The inner screw portion 3 is a portion where an inner screw is formed on the inner circumference. The inner screw is a portion screwed with the bolt 8. The inner screw portion 3 is a portion where the inner screw 3a is formed on the inner circumference of the through hole (see FIG. 3). As the inner screw portion 3, specifically, a nut 31 provided with the inner screw 3a is often used. When the nut 31 is used as the inner screw portion 3, it is fixed to the surface (upper surface) side of the lower plate portion 12 (see FIG. 3). Welding w is often used as the fixing means (see FIG. 3).

また、下板部12とナット31は、強力な接着力を有する接着剤を使用してナット31を下板部12に固着してもよい。また、下板部12のナット31の固着箇所には、ナット31の内螺子3aの孔と同一中心を有する貫通孔12aが形成される。内螺子部3として使用されるナット31は、通常の六角ナットが使用されたり、又は方形状のナットが使用される。   The lower plate portion 12 and the nut 31 may be fixed to the lower plate portion 12 by using an adhesive having a strong adhesive force. Further, a through hole 12 a having the same center as the hole of the inner screw 3 a of the nut 31 is formed in the fixing portion of the nut 31 of the lower plate portion 12. As the nut 31 used as the inner screw portion 3, a normal hexagon nut or a square nut is used.

前記上板部11及び下板部12は、方形状に形成される。具体的には、上板部11及び下板部12は長方形状又は正方形状に形成され、特に長方形に形成されることが好適である。下板部12には、前記内螺子部3を囲むようにして包持板部2が設けられる(図2,図3等参照)。包持板部2は、下板部12の外縁箇所に該下板部12に対して垂直に形成される(図3参照)。   The upper plate part 11 and the lower plate part 12 are formed in a rectangular shape. Specifically, the upper plate portion 11 and the lower plate portion 12 are formed in a rectangular shape or a square shape, and it is particularly preferable that they are formed in a rectangular shape. The lower plate portion 12 is provided with a wrapping plate portion 2 so as to surround the inner screw portion 3 (see FIGS. 2 and 3 and the like). The enclosing plate portion 2 is formed at an outer edge portion of the lower plate portion 12 so as to be perpendicular to the lower plate portion 12 (see FIG. 3).

包持板部2は、方形形(長方形)状とした下板部12における垂下状板部13の位置を除く3個の端辺に設けられる構成としている。つまり、方形(長方形)状とした下板部12の4辺は、その1つの辺が垂下状板部13で、その他の3辺は包持板部2によって囲まれた構造となる(図2参照)。そして、この場合、垂下状板部13と3個の包持板部2は、隣接部分が近接することなく、適宜な隙間を有するようにして間欠的に設けられることが好ましい〔図2(A),図3(B)等参照〕。   The holding plate portion 2 is provided on three end sides of the lower plate portion 12 having a rectangular (rectangular) shape except the position of the hanging plate portion 13. In other words, the four sides of the rectangular (rectangular) lower plate portion 12 have a structure in which one side is surrounded by the hanging plate portion 13 and the other three sides are surrounded by the holding plate portion 2 (FIG. 2). reference). In this case, it is preferable that the hanging plate portion 13 and the three holding plate portions 2 are provided intermittently so that adjacent portions do not come close to each other and have appropriate gaps [Fig. 2 (A ), See FIG. 3 (B), etc.].

また、建築用金具の第1実施形態の変形例として、包持板部2は、下板部12に対して略垂直状でも構わない。具体的には、下板部12に対して包持板部2の上方部分が外方に向かうように傾斜状に形成されることもある(図4参照)。下板部12に形成される複数の包持板部2において、全ての包持板部2は、下板部12の表面(上面)からの高さ寸法は、同一寸法である。   Further, as a modified example of the first embodiment of the building metal fitting, the enclosing plate portion 2 may be substantially vertical to the lower plate portion 12. Specifically, the upper part of the holding plate part 2 may be formed to be inclined with respect to the lower plate part 12 so as to face outward (see FIG. 4). In the plurality of holding plate portions 2 formed on the lower plate portion 12, all the holding plate portions 2 have the same height dimension from the surface (upper surface) of the lower plate portion 12.

これによって、タイトフレーム5の頂部51に装着したときに、全ての包持板部2の頂点は前記頂部51の裏面側に当接することができ、これによって、後述ボルトで締付固定したときの装着における安定性を得ることができる。また、包持板部2の上端と上板部11の下面(裏面)側との間には空隙sが存在する。該空隙sは、後述するタイトフレームの金属帯板の厚さ寸法tよりも僅かに大きい程度に設定されている(図5参照)。   As a result, when it is mounted on the top portion 51 of the tight frame 5, all the apexes of the holding plate portions 2 can abut against the back surface side of the top portion 51, whereby when the bolts are tightened and fixed as described below. It is possible to obtain stability in mounting. Further, there is a space s between the upper end of the holding plate portion 2 and the lower surface (back surface) side of the upper plate portion 11. The gap s is set to be slightly larger than the thickness dimension t of the metal frame plate of the tight frame described later (see FIG. 5).

また、包持板部2の下板部12表面からの高さ寸法H1は、内螺子部3の下板部12表面からの高さ寸法H2と、同等以下としている。
つまり、

である。 Further, the height dimension H1 from the surface of the lower plate portion 12 of the holding plate portion 2 is equal to or less than the height dimension H2 from the surface of the lower plate portion 12 of the inner screw portion 3.
That is,
Figure 2020076252
Is.

そして、好ましくは、包持板部2の下板部12表面からの高さ寸法H2は、包持板部2の下板部12表面からの高さ寸法H1より小さくすることが好適である〔図3(B),(C)参照〕。これによって、タイトフレームの頂部51に装着したときに、3個の包持板部2の上端が頂部51の下面(裏面)側に当接し、建築用金具はタイトフレーム5に対して3点の当接により極めて安定した状態で設置ができる。   Further, it is preferable that the height dimension H2 from the surface of the lower plate portion 12 of the holding plate portion 2 be smaller than the height dimension H1 from the surface of the lower plate portion 12 of the holding plate portion 2 [ See FIGS. 3 (B) and 3 (C)]. As a result, when mounted on the top portion 51 of the tight frame, the upper ends of the three holding plate portions 2 come into contact with the lower surface (back surface) side of the top portion 51, and the building metal fittings are attached to the tight frame 5 at three points. It can be installed in a very stable state by contact.

また、本発明の建築用金具の第2実施形態として、包持板部2が形成されない実施形態も存在する。この実施形態では、本体部1を構成する上板部11,下板部12及び垂下状板部13と、内螺子部3とのみから構成される(図6参照)。この実施形態では包持板部2が存在しないので、上板部11が垂下状板部13を介して下板部12側に近接及び復元が可能な弾性変形ができるものである。これによって、建築用金具をタイトフレーム5の頂部51に装着したときに、該頂部51を上板部11と内螺子部3とで略挟持状態にすることができ、最も簡単な構成にて十分な効果を発揮できる。   Further, as a second embodiment of the building metal fitting of the present invention, there is also an embodiment in which the holding plate portion 2 is not formed. In this embodiment, the main body 1 is composed only of the upper plate portion 11, the lower plate portion 12, the hanging plate portion 13, and the inner screw portion 3 (see FIG. 6). In this embodiment, since the holding plate portion 2 does not exist, the upper plate portion 11 can be elastically deformed so as to be able to approach and restore to the lower plate portion 12 side via the hanging plate portion 13. As a result, when the building metal fitting is attached to the top portion 51 of the tight frame 5, the top portion 51 can be substantially sandwiched between the upper plate portion 11 and the inner screw portion 3, and the simplest configuration is sufficient. You can exert the effect.

本発明の建築用金具の第3実施形態として、内螺子部3は、下板部12の貫通孔12a箇所の周囲から上方に向かってバーリング32が形成され、該バーリング32の内周に内螺子3aが形成される構成とすることもある〔図7(A)参照〕。また、本発明の建築用金具の第4実施形態として、内螺子部3として、下板部12の貫通孔12aの内周に内螺子3aが形成される構成とすることもある〔図7(B)参照〕。   As a third embodiment of the building metal fitting of the present invention, in the inner screw portion 3, a burring 32 is formed upward from the periphery of the through hole 12a of the lower plate portion 12, and the inner screw is formed on the inner periphery of the burring 32. 3a may be formed (see FIG. 7A). Further, as a fourth embodiment of the building metal fitting of the present invention, the inner screw 3 may be formed on the inner periphery of the through hole 12a of the lower plate 12 as the inner screw 3 [FIG. B)].

次に、タイトフレーム5は、頂部51の幅方向両側より脚部52,52が形成され、前記頂部51と2つの脚部52,52によって、略台形の山形を構成している。両脚部52,52は幅方向において略左右対称となるように形成される。両脚部52,52の下端箇所より水平状の底部53,53が形成されている。両底部53,53は、幅方向に沿って延在するように形成されている〔図1(A)参照〕。   Next, the tight frame 5 has leg portions 52 and 52 formed from both sides in the width direction of the top portion 51, and the top portion 51 and the two leg portions 52 and 52 form a substantially trapezoidal mountain shape. Both legs 52, 52 are formed so as to be substantially bilaterally symmetrical in the width direction. Horizontal bottom portions 53, 53 are formed from the lower end portions of both leg portions 52, 52. Both bottom portions 53, 53 are formed so as to extend along the width direction [see FIG. 1 (A)].

頂部51は、施工される折板屋根を構成する建築用板材7の種類によって、平坦状或いは2段の高低面に形成される。頂部51が2段の高低面としたものでは、馳締タイプの折板屋根に適応したものであり、頂部51の幅方向中間箇所に段差部51cが形成され、該段差部51cの一方の面を低位面51aとし、他方を高位面51bとする〔図1(A),図2(A)参照〕。低位面51aには、金属製の折板屋根板材を固定するための吊子6が設置される部位となっている。両脚部52,52は、前記頂部51の幅方向両端から外方下向きに傾斜するようにして形成されたものである。   The top portion 51 is formed in a flat shape or a two-level high or low surface depending on the type of the building plate material 7 that constitutes the folded plate roof to be constructed. When the top 51 has a two-step high and low surface, it is suitable for a folding type folded plate roof, and a step 51c is formed at an intermediate portion in the width direction of the top 51, and one surface of the step 51c is formed. Is a lower surface 51a and the other is a higher surface 51b [see FIGS. 1 (A) and 2 (A)]. The lower surface 51a is a portion where the suspension 6 for fixing the metal folding plate roof plate material is installed. The two leg portions 52, 52 are formed so as to incline outward and downward from both ends in the width direction of the top portion 51.

建築用板材7は、種々の折板タイプが存在するものであり、馳締タイプ〔図1(A)参照〕、嵌合キャップ材を使用する嵌合タイプ(図8参照)が存在する。馳締タイプの建築用板材7としては、図1(A)に示すように、主板71の幅方向両側部分より立上り側部72,72が形成され、両立上り側部72,72の両端より頂部73,73が形成され、両該頂部73,73の一方の端から下馳部74aが形成され,他方の頂部73の端には上馳部74bが形成されている。   There are various folded plate types for the building plate material 7, and there are a fastening type [see FIG. 1 (A)] and a fitting type using a fitting cap material (see FIG. 8). As shown in FIG. 1 (A), the fastening type building board 7 has rising side portions 72, 72 formed from both side portions of the main plate 71 in the width direction, and the top portions are formed from both ends of the compatible rising side portions 72, 72. 73, 73 are formed, a lower opening portion 74a is formed from one end of each of the top portions 73, 73, and an upper opening portion 74b is formed at the end of the other top portion 73.

前記建築用板材7は、金属製であり、具体的には金属板からドラム成形等によって成形されたものである。そして、このような建築用板材7,7,…が複数並設され、隣接する建築用板材7,7同士の下馳部74aと上馳部74bとの間に、吊子6を介して前記下馳部74aと前記上馳部74bとを馳締結合され馳締外囲体が施工される〔図1(A)参照〕。   The building plate material 7 is made of metal, and specifically, is formed by drum molding or the like from a metal plate. A plurality of such building plates 7, 7, ... Are arranged side by side, and the adjacent building plates 7, 7 are sandwiched between the lower recess portion 74a and the upper recess portion 74b with the suspension 6 interposed therebetween. The lower casing portion 74a and the upper casing portion 74b are fastened and coupled to each other to construct a fastening outer casing (see FIG. 1 (A)).

嵌合タイプの折板屋根板では、被嵌合部76と、嵌合キャップ材77とから構成される。このタイプの建築用板材7に適応する嵌合吊子等の吊子6が使用される。そして、隣接する建築用板材7,7の対向する被嵌合部76,76が前記吊子6によってタイトフレーム5の頂部51上に固定され、対向する前記被嵌合部76,76と前記吊子6に前記嵌合キャップ材77が嵌合固定される(図8参照)。   The fitting-type folded plate roof plate includes a fitted portion 76 and a fitting cap member 77. A hanger 6 such as a fitting hanger adapted to this type of building board 7 is used. Then, the fitted parts 76, 76 facing each other of the adjacent building board members 7, 7 are fixed on the top 51 of the tight frame 5 by the hanger 6, and the fitted parts 76, 76 facing each other and the hanging part are fixed. The fitting cap member 77 is fitted and fixed to the child 6 (see FIG. 8).

次に、本発明の建築用金具によって、タイトフレーム5に吊子6を装着し、折板屋根の施工を行う工程について説明する。ここで、タイトフレーム5は、馳締タイプの折板屋根の施工の場合について説明する。タイトフレーム5は、金属製の帯板材から形成されたものである。タイトフレーム5における頂部51は、2段の高低両面に形成されたものであり、該頂部51は、幅方向中間箇所に段差部51cが形成され、該段差部51cの一方の面の低位面51aに貫通孔51dが形成されている(図1,図2,図5参照)。   Next, a process of mounting the hanging frame 6 on the tight frame 5 and constructing a folded plate roof with the building metal fitting of the present invention will be described. Here, the tight frame 5 will be described in the case of the construction of a folding type folded plate roof. The tight frame 5 is made of a metal strip material. The top portion 51 of the tight frame 5 is formed on both upper and lower surfaces in two steps. The top portion 51 has a step portion 51c formed at an intermediate position in the width direction, and the lower surface 51a on one surface of the step portion 51c. A through hole 51d is formed at the bottom (see FIGS. 1, 2, and 5).

まず、タイトフレーム5は、建築構造物の鉄骨梁等の構造材9上に所定間隔を置いて配置固着される。タイトフレーム5の頂部51の低位面51aに、本発明の建築用金具が装着される〔図2(A),図5(A)参照〕。このとき、建築用金具の上板部11と下板部12との間に低位面51aが挿入するように建築用金具を頂部51に差し込み、上板部11と下板部12とによって低位面51aを挟持する構成とする〔図5(B)参照〕。   First, the tight frame 5 is arranged and fixed at a predetermined interval on a structural material 9 such as a steel frame beam of a building structure. The metal fitting for construction of the present invention is attached to the lower surface 51a of the top portion 51 of the tight frame 5 [see FIGS. 2 (A) and 5 (A)]. At this time, the building metal fitting is inserted into the top portion 51 so that the lower surface 51a is inserted between the upper plate portion 11 and the lower plate portion 12 of the building metal fitting, and the lower surface is formed by the upper plate portion 11 and the lower plate portion 12. 51a is sandwiched [see FIG. 5 (B)].

そして、建築用金具の上板部11の開口孔11aと、タイトフレーム5の貫通孔51dとの位置を一致するように合わせる。この開口孔11aと貫通孔51dの位置が一致すると、低位面51aの貫通孔51dは、内螺子部3及び下板部12の貫通孔12aと一致するようになっている〔図5(B)参照〕。   Then, the opening hole 11a of the upper plate portion 11 of the building metal fitting and the through hole 51d of the tight frame 5 are aligned so as to be aligned with each other. When the positions of the opening hole 11a and the through hole 51d coincide with each other, the through hole 51d of the lower surface 51a coincides with the through hole 12a of the inner screw portion 3 and the lower plate portion 12 (FIG. 5 (B)). reference〕.

次に、タイトフレーム5の低位面51aに装着した建築用金具の上板部11上に吊子6を載置する。そして、吊子6の座板部61の取付孔61aを、建築用金具の上板部11の開口孔11aに互いに位置を一致させる。そして、ボルト8を挿入し、該ボルト8と内螺子部3の内螺子3aとを螺合させて締め付ける。ここで、下板部12には、包持板部2が形成されており、該包持板部2の上端がタイトフレーム5の低位面51aの下面(裏面)側に当接する〔図5(C)参照〕。   Next, the hanger 6 is placed on the upper plate portion 11 of the building metal fitting mounted on the lower surface 51a of the tight frame 5. Then, the mounting holes 61a of the seat plate portion 61 of the suspension 6 are aligned with the opening holes 11a of the upper plate portion 11 of the building metal fitting. Then, the bolt 8 is inserted, and the bolt 8 and the inner screw 3a of the inner screw portion 3 are screwed together and tightened. Here, the lower plate portion 12 is provided with a wrapping plate portion 2, and the upper end of the wrapping plate portion 2 contacts the lower surface (back surface) side of the lower surface 51a of the tight frame 5 [FIG. See C)].

下板部12が長方形の場合では、該下板部12の幅方向両端及び前後方向の一端に包持板部2がそれぞれ設けられており、これらの3個の包持板部2の上端が低位面51aの下面(裏面)側に当接し、建築用金具はタイトフレーム5の低位面51aに対して安定した設置ができる。ここで、内螺子部3の上端の高さが、包持板部2の上端の高さよりも低い場合には、包持板部2のみが低位面51aに当接する。   When the lower plate portion 12 is rectangular, the wrapping plate portions 2 are provided at both ends in the width direction and one end in the front-rear direction of the lower plate portion 12, and the upper ends of these three wrapping plate portions 2 are By contacting the lower surface (back surface) side of the lower surface 51a, the building metal fitting can be stably installed on the lower surface 51a of the tight frame 5. Here, when the height of the upper end of the inner screw portion 3 is lower than the height of the upper end of the wrapping plate portion 2, only the wrapping plate portion 2 contacts the lower surface 51a.

また、内螺子部3の高さと包持板部2の高さが同等の場合には、包持板部2と内螺子部3が共に低位面51aに当接する。タイトフレーム5に建築用金具を介して設置された吊子6は、その舌片62に辺に馳締タイプの折板建築用板材7の下馳部74aが装着され、次いで、隣接する建築用板材7の上馳部74bが舌片62及び下馳部74a上に馳締される。この作業が順次繰り返されて、馳締タイプの折板屋根の施工が行われる。   When the height of the inner screw portion 3 and the height of the wrapping plate portion 2 are the same, both the wrapping plate portion 2 and the inner screw portion 3 contact the lower surface 51a. The tongue piece 62 of the suspension 6 installed on the tight frame 5 via the metal fittings for mounting has the lower part 74a of the plate type building plate 7 of the fastening type on the side, and then the adjacent building The upper lip portion 74b of the plate member 7 is fastened on the tongue piece 62 and the lower lip portion 74a. This work is repeated in sequence to construct a lock type folding plate roof.

また、嵌合タイプの折板屋根板の施工では、タイトフレーム5の頂部51は段差の存在しない平坦なタイプのものが使用される。吊子6は、座板61の幅方向両側に舌片62,62が形成されたものである。そして、建築用金具の上板部11と下板部12との間にタイトフレーム5の平坦な頂部51が挿入するように建築用金具を頂部51に差し込み上板部11と下板部12とによって低位面51aを挟持する構成とする〔図8(B)参照〕。   Further, in the fitting type folding plate roof plate construction, the top portion 51 of the tight frame 5 is a flat type having no step. The suspension 6 has tongue pieces 62, 62 formed on both sides of the seat plate 61 in the width direction. Then, the building metal fitting is inserted into the top portion 51 so that the flat top portion 51 of the tight frame 5 is inserted between the upper plate portion 11 and the lower plate portion 12 of the building metal fitting, and the upper plate portion 11 and the lower plate portion 12 are The lower surface 51a is sandwiched between the two (see FIG. 8B).

そして、建築用金具の上板部11の開口孔11aと、タイトフレーム5の貫通孔51dと、内螺子部3及び下板部12の貫通孔12aと一致させる。次に、建築用金具の上板部11上に吊子6を載置し、吊子6の座板部61の取付孔61aを、建築用金具の上板部11の開口孔11aに互いに位置を一致させ、ボルト8を挿入し、該ボルト8と内螺子部3の内螺子3aとを螺合させて締め付ける。   Then, the opening hole 11a of the upper plate portion 11 of the building metal fitting, the through hole 51d of the tight frame 5, and the through hole 12a of the inner screw portion 3 and the lower plate portion 12 are aligned. Next, the hanger 6 is placed on the upper plate part 11 of the building metal fitting, and the mounting holes 61a of the seat plate part 61 of the hanger 6 are positioned relative to the opening holes 11a of the upper plate part 11 of the metal fitting. And the bolt 8 is inserted, and the bolt 8 and the inner screw 3a of the inner screw portion 3 are screwed together and tightened.

次いで、隣接する建築用板材7,7の対向する被嵌合部76,76が、前記吊子6の幅方向両側の舌片62,62にて巻き付けられ、被嵌合部76,76及び吊子6の上から嵌合キャップ材77が嵌合固定される。この作業が順次繰り返されて、嵌合タイプの折板屋根の施工が行われる(図8参照)。   Next, the fitted parts 76, 76 facing each other of the adjacent building board members 7, 7 are wound around the tongue pieces 62, 62 on both sides in the width direction of the hanger 6, and the fitted parts 76, 76 and the hanging parts are hung. The fitting cap member 77 is fitted and fixed from above the child 6. This work is sequentially repeated to perform fitting type folding plate roof construction (see FIG. 8).
