Description

The present invention relates to a wall structure of a temporary building and a construction method thereof.

Temporary buildings are being used for various purposes such as temporary arenas for outdoor events, temporary housing that requires immediate construction after the earthquake, and temporary accommodation facilities, and construction is planned. Here, an example of the wall structure of the conventional temporary building will be described with reference to FIG. FIG. 1 is a cross-sectional view of the wall structure of a conventional temporary building, and is a view of the cross-sectional view (horizontal cross-section) viewed from above.

In the wall structure 200 of the temporary building shown in FIG. 1, the outer wall surface material 1 made of a metal siding board, a ceramic siding board, or the like is screwed to an outer wall column 2 made of a lightweight steel square steel pipe or the like, and the inner wall surface material 6 is also. Similarly, the inner wall surface material 6 is fixed to the outer wall column 2, and the inner wall surface material 6 is further fixed to the inner wall base material 4 made of a plurality of lightweight channel steels or the like to form the whole. The outer wall surface material 1 is fixed not only to the outer wall column 2 but also to the outer wall base material (stud) 3 made of lightweight channel steel or the like arranged between the outer wall columns 2. On the outdoor side surface of the outer wall pillar 2, for example, outer wall material 1 is attached to the left and right sides of the outer wall column 2 via a dry type vertical joint 1a.

Further, a plate 2a overhanging sideways is welded to the side surface of the outer wall pillar 2, and a vertically extending mounting vertical furring strip made of lightweight channel steel or the like is formed at the widthwise end of the outer wall material 1. 1b is screwed, the outer wall material 1 is directly screwed to the outer wall pillar 2, and the mounting vertical furring strip 1b is bolted to the plate 2a, so that the outer wall material 1 with respect to the outer wall pillar 2 is fixed. It is installed. In addition, the outer wall surface material 1, the outer wall base material 3, and the mounting vertical furring strip 1b can be referred to as an outer wall panel.

At the lower and upper ends of the wall structure 200, a U-shaped runner having a U-shaped cross section extending in the width direction of the outer wall surface material 1 is laid in a posture in which the U-shaped opening is directed toward the inner wall base material 4, and a plurality of them are laid. The inner wall base material 4 is fitted and fixed to the runners having a U-shaped cross section located above and below them. Note that FIG. 1 shows the lower runner 5 among the upper and lower runners. The inner wall surface material 6 is fixed to the outer wall pillar 2 and is also fixed to a plurality of inner wall base materials 4 fixed to the upper and lower runners. That is, as shown in FIG. 1, the dimensions t1 and t2 in the wall thickness direction of the outer wall pillar 2 and the outer wall base material 3 are generally different from each other, and more specifically, the dimension t1 of the outer wall pillar 2 is Since it is generally relatively large, the inner wall surface material 6 cannot be fixed on the indoor side surface of both the outer wall pillar 2 and the outer wall base material 3. Therefore, in the conventional wall structure 200, a configuration is adopted in which the inner wall surface material 6 is fixed to the outer wall pillar 2 and is fixed by a plurality of inner wall base materials 4 arranged flush with the indoor side surface of the outer wall pillar 2. ing.

Further, since gypsum board or calcium silicate board is generally applied to the inner wall surface material 6, a finishing material 6a such as cloth is generally provided on the indoor surface of the inner wall surface material 6. .. Further, since the inner wall surface material 6 is formed of gypsum board or the like, the wall space between the outer wall surface material 1 and the inner wall surface material 6 is filled with a heat insulating material 7 such as glass wool to provide heat insulating properties of the temporary building. Is guaranteed.

As described above, in the wall structure 200 of the conventional temporary building, a plurality of inner wall base materials 4 for fixing the inner wall surface material 6 are indispensable configurations, and the number of parts (the number of parts) when forming the wall structure 200 even though it is a temporary building. In particular, there is a problem that the number of parts of lightweight shaped steel) increases. Although it is a temporary building with a relatively short service period, since the inner wall material 6 is firmly fixed to the outer wall pillar 2 and the inner wall base material 4 with screws or the like, it takes time and effort to construct and dismantle the wall structure 200. It has a problem that it requires.

Further, since it is necessary to provide the finishing material 6a on the surface of the inner wall surface material 6, and further, it is necessary to fill the wall space between the outer wall surface material 1 and the inner wall surface material 6 with the heat insulating material 7, so that the inner wall base material is used. There is also a problem that the number of construction processes increases due to the installation of the material 4 and the heat insulating material 7.

Here, there has been proposed a sound-absorbing and heat-insulating material fitting that allows the sound-absorbing and heat-insulating material to be attached to the inner wall surface of a building at a predetermined interval (see, for example, Patent Document 1).

Jikkenhei 5-54707 Gazette

However, even if the sound absorbing and heat insulating material attachment described in Patent Document 1 is applied to the wall structure of a conventional temporary building, it is not possible to eliminate the attachment of a plurality of inner wall base materials for fixing the inner wall material. It is not possible to solve the problems such as the large number of parts in the wall structure of the temporary building and the large number of construction processes.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a wall structure of a temporary building which can eliminate the need for attachment of an inner wall base material and has good workability, and a construction method thereof.

In order to achieve the above object, one aspect of the wall structure of the temporary building according to the present invention is
Multiple outer wall columns arranged at predetermined intervals,
The outer wall material fixed to the plurality of outer wall pillars,
A plurality of outer wall base materials having a lower horizontal cross section than the outer wall pillar, which are arranged between the outer wall pillars and fix the outer wall material, are provided.
It has an upper runner and a lower runner at the upper and lower positions on the indoor side of the outer wall pillar.
Each of the outer wall base materials has a plurality of stages of spacers on the side surface on the indoor side at intervals in the vertical direction, and common horizontal joints are attached to the spacers of each stage.
The lower runner and the horizontal joint sandwich and fix the inner wall material from the top and bottom to the bottom, and the upper runner and the horizontal joint sandwich and fix the inner wall material from the top and bottom to the upper side, and a plurality of pieces arranged in the vertical direction. The inner wall material unit is formed by the inner wall material, and the inner wall material unit is formed.
A plurality of the inner wall surface material units are arranged in the arrangement direction of the outer wall columns.

According to this aspect, among the outer wall pillars and the outer wall base material whose indoor side surfaces are not flush with each other, the height in the horizontal cross section is lower (dimensions from the outer wall material to the inner wall material) while eliminating the need for the inner wall base material. By attaching a spacer to the indoor side surface of the outer wall base material, the inner wall material can be fixed to the outer wall pillar and the outer wall base material. Temporary buildings having the wall structure of this embodiment include temporary buildings such as temporary housing and temporary arenas, which have a relatively short service period, as well as general buildings such as machine rooms installed in the basement of buildings and rooftops. Includes non-residential facilities, etc. attached to living rooms, etc.

Here, a plurality of horizontal joints are arranged between the upper runner and the lower runner, and each horizontal joint is fixed to a spacer attached to the plurality of outer wall base materials. That is, spacers are attached to the side surfaces of each outer wall base material extending in the vertical direction on the indoor side at positions corresponding to a plurality of horizontal joints.

In the wall structure of the temporary building of this embodiment, the inner wall surface material is sandwiched and fixed from above and below by the upper runner, the horizontal joint, and the lower runner, so that the outer wall pillar and the outer wall base material (spacer attached to) can be fixed. The inner wall material is fixed.

Further, in another aspect of the wall structure of the temporary building according to the present invention, there is an intermediate inner wall surface material between the lower inner wall surface material and the upper inner wall surface material, and the horizontal joints in a vertical relationship are used. The inner wall surface material in the middle is sandwiched and fixed from above and below.

According to this aspect, one inner wall material is formed by forming the inner wall material unit from one or more intermediate inner wall materials in addition to the upper inner wall material and the lower inner wall material. The dimensions of can be set to the dimensions suitable for transportation and assembly. If there is one intermediate inner wall surface material, there are two horizontal joints that cross the inner wall surface material unit, and if there are two intermediate inner wall surface materials, there are three horizontal joints.

Further, another aspect of the wall structure of the temporary building according to the present invention is characterized in that vertical joints are inserted between the adjacent inner wall surface material units.

According to this aspect, vertical joints are inserted between the inner wall surface material unit formed from the inner wall surface materials arranged one above the other and the inner wall surface material unit to reinforce the prevention of the inner wall surface material from falling to the indoor side. However, by providing the vertical joints, it is possible to give an accent to the arrangement of the inner wall material units in the horizontal direction, and it is possible to enhance the design from the indoor side.

Further, in another aspect of the wall structure of the temporary building according to the present invention, the horizontal joint has a fixing piece fixed to the spacer and an upper end or a lower end of the inner wall surface material extending inward from the fixing piece. It has a sandwiching piece, and the sandwiching piece is characterized by having irregularities that engage with the end portion of the inner wall surface material on the upper and lower side surfaces on the distal end side.

According to this aspect, since the sandwiching piece having the horizontal joint has unevenness on the upper and lower side surfaces on the tip side thereof, the unevenness fits into the end portion of the inner wall surface material, so that the horizontal joint and the inner wall surface material are formed. An engaged state can be formed.

Further, in another aspect of the wall structure of the temporary building according to the present invention, the horizontal joint is formed of a resin material, and the sandwiching piece of the horizontal joint and the inner wall surface material are fixed by studs. And.

According to this aspect, since the horizontal joint is formed of the resin material, the horizontal joint and the inner wall surface material can be fixed by the studs. Here, the "tack" includes not only a normal thumbtack but also a carpet stud that fixes a carpet to a floor material.

Further, in another aspect of the wall structure of the temporary building according to the present invention, the vertical joint is a support piece that is exposed to the indoor side and supports the adjacent inner wall material unit from the indoor side, and extends from the support piece. It has an insertion piece inserted between the adjacent inner wall surface material units, and the insertion piece has irregularities that engage with the end surface of the inner wall surface material on the left and right side surfaces on the tip side. It is characterized by.

According to this aspect, since the insertion piece of the vertical joint has unevenness that engages with the end surface of the inner wall surface material, the vertical joint is formed only by inserting the vertical joint between the adjacent inner wall surface material units. It can be fixed to the inner wall material unit. Since each horizontal joint has a length between the outer wall pillar and the outer wall pillar, for example, the horizontal joint extending in the horizontal direction at the center position of the outer wall pillar is trimmed. Then, since a structure can be formed in which the tip of the vertical joint is inserted between the horizontal joints cut in the horizontal direction, it is possible to eliminate the mutual interference between the horizontal joint and the vertical joint. Regarding this, in the conventional wall structure, since both the horizontal joint and the vertical joint are fixed to the outer wall pillar, the spacer, etc., an interference part between the horizontal joint and the vertical joint always occurs, and one of them is cut at the interference position. It was necessary to take measures such as.

Further, in another aspect of the wall structure of the temporary building according to the present invention, the upper runner and the lower runner both have a female runner and a male runner that engages with the female runner.
The upper end or the lower end of the inner wall surface material is attached to either the female runner or the male runner of the upper runner and the lower runner attached to the constituent members at the upper and lower positions of the temporary building. It is characterized in that the female runner and the other of the male runners are engaged with each other so as to be sandwiched between them.

According to this aspect, both the upper runner and the lower runner have a female runner and a male runner that engage with each other, and one of the female runner and the male runner is previously provided with respect to the components located at the upper and lower positions of the temporary building. Is attached, and after the inner wall material is installed, the other of the female runner and the male runner is engaged to form the upper runner and the lower runner, so that the attachment is easy when the relatively hard inner wall material is attached. Become good. When applying a relatively soft inner wall material, even if the conventional upper runner and lower runner with a U-shaped cross section with the openings facing up and down are applied, the upper runner, etc. while deforming the inner wall material, etc. Can be plugged into.

Further, another aspect of the wall structure of the temporary building according to the present invention is characterized in that the inner wall surface material is glass wool board.

According to this aspect, by having the inner wall material made of glass wool board, the inner wall material itself has the heat insulating performance, and therefore, the wall space between the outer wall material and the inner wall material is filled with the heat insulating material. It is possible to guarantee the heat insulation of the temporary building while eliminating the need for construction. Moreover, since the inner wall surface material is glass wool board, it is not necessary to construct a surface finishing material like gypsum board. From these facts, it is possible to reduce the construction process as compared with the wall structure of the conventional temporary building, and it is possible to provide a simple wall structure having excellent heat insulating properties. Further, since the glass wool board has sound absorption and nonflammability, it is possible to form a wall structure of a temporary building provided with an inner wall material having sound absorption and nonflammability.

Further, one aspect of the construction method of the wall structure of the temporary building according to the present invention is as follows.

The wall structure of the temporary building is provided with a plurality of outer wall base materials having a low height in the horizontal cross section, and the inner wall material is attached to the indoor side of the outer wall pillar and the outer wall base material to construct the wall structure of the temporary building. It is a construction method of
A runner and spacer mounting process in which an upper runner and a lower runner are attached to the upper and lower positions on the indoor side of the outer wall pillar, and a plurality of spacers are attached to the side surfaces of the outer wall base material on the indoor side.
By attaching the lower inner wall material to the lower runner and attaching a common horizontal joint to each of the spacers, the lower runner and the horizontal joint sandwich and fix the lower inner wall material from above and below. The lower inner wall material fixing process and
By placing an intermediate inner wall surface material on the horizontal joint above the lower inner wall material and attaching a common horizontal joint to the spacer, the upper and lower horizontal joints are used from above and below to the middle. An intermediate inner wall material fixing process that sandwiches and fixes the inner wall material of
By placing the upper inner wall material on the horizontal joint above the intermediate inner wall material and fixing the upper inner wall material from above and below by the upper runner and the horizontal joint. An inner wall surface material unit forming step of forming an inner wall surface material unit from a plurality of the inner wall surface materials arranged in the vertical direction, and
It is characterized in that a plurality of the inner wall surface material units are formed by two or more of the inner wall surface material unit forming steps, and vertical joints are inserted between the adjacent inner wall surface material units to construct a wall structure of a temporary building. ..

According to this aspect, after attaching the upper runner, the lower runner, and the spacer, the lower inner wall material is attached to the lower runner, the horizontal joint, the middle inner wall material, and the horizontal joint are attached in order, and further the upper inner wall material is attached. By attaching the wall material to the upper runner, it is possible to efficiently construct the inner wall material unit composed of a plurality of inner wall materials arranged in the vertical direction. In this way, after the inner wall material units are arranged horizontally on the indoor side to construct a plurality of inner wall material units, a vertical joint is inserted between the adjacent inner wall material units to construct the inner wall, so that the temporary building is constructed. The inner wall forming the wall structure of the above can be efficiently constructed, and therefore the entire wall structure of the temporary building can be efficiently constructed.

Further, in this construction method, as described above, for example, by applying a horizontal joint having a length between the outer wall pillar and the core of the outer wall pillar, the horizontal joint extending in the horizontal direction at the center position of the outer wall pillar is applied. A gap is formed (edge is cut) between the two. Then, since the structure can be formed so that the tip of the vertical joint is inserted into the gap between the horizontal joints arranged in the horizontal direction, the vertical joint to be constructed later can be inserted without interfering with the horizontal joint. ..

In addition, when dismantling the wall structure of a temporary building, the wall structure is dismantled without damaging each component by removing each component in the procedure opposite to the construction method according to this embodiment. be able to. Therefore, each component after removal can be reused.

Further, in another aspect of the construction method of the wall structure of the temporary building according to the present invention, the horizontal joint is formed of a resin material, a fixed piece fixed to the spacer, and a fixed piece extending from the fixed piece to the indoor side. It has a sandwiching piece that sandwiches the upper end or the lower end of the inner wall surface material.
It is characterized in that the sandwiching piece of the horizontal joint and the inner wall surface material are fixed with a stud.

According to this aspect, even better workability can be obtained by fixing the sandwiching piece of the horizontal joint formed from the resin material and the inner wall surface material with a stud.

As can be understood from the above explanation, according to the wall structure of the temporary building and the construction method thereof of the present invention, it has good workability while eliminating the need to attach the inner wall base material, and further, each configuration after dismantling. The members can be reused.

In the present specification and the drawings, substantially the same components may be designated by the same reference numerals to omit duplicate explanations.

[Wall structure of temporary building and its construction method according to the embodiment]
An example of the wall structure of the temporary building and an example of the construction method thereof according to the embodiment will be described with reference to FIGS. 2 to 15.

In FIG. 2, four outer wall base materials 3 made of lightweight lip channel steel are arranged between outer wall columns 2 made of two lightweight steel square steel pipes and the like, and the outer wall base materials 3 are continuous grooves. A part of the structural surface integrally connected by the shaped steel 91 is shown. A brace 92 made of round steel or the like is arranged in this structure.

In the construction method of the wall structure of the temporary building, first, as shown in FIG. 2, the outer wall pillar 2 and the outer wall base material 3 forming the wall structure are built, and the outer wall pillar 2 and the outer wall base material 3 are not shown. Along with attaching the material, the brace 92 is attached to the indoor side of the outer wall pillar 2 and the like.

Further, a female runner 11 forming a lower runner is arranged on the inner side surface of the lower end of the outer wall pillar 2 on the indoor side, and is fixed to the floor plate or the like with a screw or the like. The female runner 11 is formed of a resin material like the male runner described later and the horizontal joints and vertical joints described later. This resin material is not particularly limited, but a resin material having an appropriate hardness and an appropriate deformation performance such as polyethylene and polypropylene is preferable. As in the conventional wall structure shown in FIG. 1, both the lower runner and the upper runner may be formed of a metal runner having a U-shaped cross section.

Further, as shown in FIG. 2, the spacer 8 is attached to a plurality of common level positions in each outer wall base material 3. FIG. 2 shows a state in which the spacer 8 is attached to each outer wall base material 3 at two level positions.

Here, FIG. 3 shows a perspective view of an example of the spacer. The spacer 8 shown in the figure is formed of metal as a whole, and is an adjustment that is fixed to the mounting piece 81 by welding or the like with the mounting piece 81 having a screw hole 81a to which a horizontal joint (not shown) is mounted. It has a bolt 84 and an engaging body 82 whose separation from the mounting piece 81 is adjusted while being screwed to and rotated by the adjusting bolt 84. It is not necessary that the screw hole 81a is provided in the mounting piece 81.

The engaging body 82 has a lip insertion port 85 through which the lip of the outer wall base material 8 is inserted, and an engaging port 84 that communicates with the lip insertion port 85 and sandwiches a standing piece of channel steel together with the end surface of the adjusting bolt 83. Have. The lip of the channel steel forming the outer wall base material 8 is inserted through the lip insertion port 85, and the adjustment bolt 84 is rotated while rotating the mounting piece 81 with respect to the standing piece of the channel steel inserted in the engagement port 84. Is brought into contact with the standing piece and further pressed, so that the spacer 8 is attached at a predetermined position of the outer wall base material 3. The above is the runner and spacer mounting process in the construction method according to the embodiment.

Next, as shown in FIG. 4, the lower inner wall surface material 20A is placed on the female runner 11 of the lower runner 10, and the male runner 12 is fitted into the female runner 11 to form the lower runner 10. , The lower inner wall surface material 20A is fixed at the lower position by the lower runner 10. The lateral length of the inner wall surface material 20A is set to a length corresponding to the distance between the cores of two adjacent outer wall columns 2. As shown in FIG. 4, in a state where the lower inner wall surface material 20A is fixed, a part of the upper part of the mounting piece 81 of each spacer 8 is exposed from the upper end of the lower inner wall surface material 20A, and the screw The holes 81a are similarly exposed. In this way, when the lower inner wall surface material 20A is attached, each spacer 8 is attached to the corresponding outer wall base material 3 so that the screw holes 81a are exposed upward.

A glass wool board is applied to the inner wall surface material 20A. Here, as the glass wool board to be applied, for example, Aclear GC of the Aclear (registered trademark) series manufactured by Asahi Fiber Glass Co., Ltd. can be applied. The glass wool board is similarly applied to the other inner wall surface materials 20B and 20C shown below, but the inner wall surface material 20A will be described as a representative.

By applying the glass wool board to the inner wall surface material 20A, the inner wall surface material 20A itself has a heat insulating performance, and therefore, in the wall space between the outer wall surface material 1 and the inner wall surface material 20A, the wall structure shown in FIG. It is possible to eliminate the need to fill and construct the heat insulating material 7 as in the case of 200. Further, since the inner wall surface material 20A is a glass wool board, it is possible to eliminate the need for the construction of a surface finishing material as in the gypsum board which is the inner wall surface material 6 of the wall structure 200 shown in FIG.

From these facts, in the wall structure having the inner wall surface material 20A made of glass wool board, the construction process can be reduced as compared with the wall structure 200 of the conventional temporary building, and the internal structure can be made as simple as possible. However, it is possible to form a wall structure having excellent heat insulating properties.

FIG. 5 is a vertical sectional view of an example of the lower end (floor side) of the wall structure. The female runner 11 of the lower runner 10 is screwed to the floor plate 30, and after the lower inner wall surface material 20A is placed on the floor plate 30, the male runner 12 is fitted into the female runner 11 from the interior space side. , The lower runner 10 is formed. In the illustrated example, the female runner 11 is fixed to the floor plate 30 and the male runner 12 is fitted, but the male runner 12 may be fixed to the floor plate 30 and the female runner 11 may be fitted. In FIG. 5, a base drainer 1b is attached below the outer wall surface material 1 fixed to the outside of the outer wall surface material 3.

As shown in FIG. 4, after the lower inner wall surface material 20A is attached to the lower runner 10, the upper end of the inner wall surface material 20A is attached to the spacer 8 via the horizontal joint. Here, FIG. 6 is a perspective view showing an example of a horizontal joint.

The sandwiching piece 42 has an unevenness 43 that engages with the end portion of the inner wall surface material 20A (and the inner wall surface material 20B shown in FIG. 8) on the upper and lower side surfaces on the tip side. Further, the horizontal joint 40 is formed of a resin material as described above.

As shown in FIG. 7, the fixing piece 41 of the horizontal joint 40 is inserted into the back side of the upper end of the inner wall surface material 20A, and fixed to the mounting piece 81 of each spacer 8 located on the back surface with a screw or the like. Further, the stud 44 is driven into the sandwiching piece 42 of the horizontal joint 40, and the horizontal joint 40 and the inner wall surface material 20A are connected by the stud 44. Since the horizontal joint 40 is made of a resin material and the inner wall surface material 20A is also made of a glass wool board, the stud 44 can be easily inserted into the inside of the glass wool board from the top of the sandwiching piece 42. Further, at this time, the unevenness 43 of the sandwiching piece 42 is fitted into the inner wall surface material 20A, so that the horizontal joint 40 and the inner wall surface material 20A are firmly engaged.

Further, as shown in FIG. 7, the length in the longitudinal direction of the horizontal joint 40 is set to a length corresponding to the distance between the cores of the two adjacent outer wall columns 2 as well as the length in the lateral direction of the inner wall surface material 20. Has been done. A horizontal joint 40 is similarly arranged between one of the left and right outer wall pillars 2 shown in the figure and the other outer wall pillar 2 not shown, but the horizontal joint 40 is trimmed at the center position of the outer wall pillar 2. By doing so, the vertical joints and the horizontal joints 40, which are attached in the post-construction, do not interfere with each other. This will be described in detail in the following section explaining the installation of vertical joints. The above is the lower inner wall surface material fixing step in the construction method according to the embodiment.

Next, as shown in FIG. 8, the intermediate inner wall surface material 20B is placed on the horizontal joint 40. In the state where the inner wall surface material 20B is placed, a part of the upper part of the mounting piece 81 of each spacer 8 is exposed from above the inner wall surface material 20B as in the case of mounting the lower inner wall surface material 20A. The screw hole 81a is similarly exposed. Although not shown, a horizontal joint is placed on the upper end of the attached intermediate inner wall surface material 20B, and the horizontal joint is fixed to the spacer 8 with a screw or the like, as in FIG. 7.

As described above, with respect to the intermediate inner wall surface material 20B, by being sandwiched by the upper and lower horizontal joints 40, the unevenness 43 of the sandwiching piece 42 of the upper and lower horizontal joints 40 is fitted to the upper and lower ends of the inner wall surface material 20B, respectively. The upper and lower horizontal joints 40 and the inner wall surface material 20B are firmly engaged with each other, and the intermediate inner wall surface material 20B is fixed.

FIG. 9 is a vertical cross-sectional view of the wall structure in the state of FIG. The sandwiching piece 42 of the horizontal joint 40 and the lower inner wall surface material 20A are fixed by the studs 44, and the unevenness 43 on the upper and lower side surfaces of the tip of the sandwiching piece 42 is formed on the upper end surface and the middle of the lower inner wall surface material 20A. It can be seen that they are fitted into and engaged with the lower end surfaces of the wall surface material 20B. The inner wall surface material 20B in the middle may be one, or two or more may be attached in the vertical direction. The above is the intermediate inner wall surface material fixing step in the construction method according to the embodiment.

After the horizontal joint 40 is mounted on the inner wall surface material 20B in the middle of the uppermost stage, as shown in FIG. 10, the upper inner wall surface material 20C is fitted into the lower surface of the female runner 51 forming the upper runner 50 to form a female. By inserting the male runner 52 into the runner 51 from the indoor side, the upper runner 50 is formed and the upper inner wall surface material 20C is fixed. The upper runner 50 is locked to the end of a ceiling surface material 70 made of, for example, gypsum board. A hanging bolt 75 is suspended from a ceiling beam made of H-shaped steel or the like (not shown), a hanger 74 is connected to the hanging bolt 75, a field edge receiver 73 is supported by the hanger 74, and the field edge receiver 73 is supported. The field 72 is supported. The ceiling surface material 70 is fixed to a plurality of field edges 72.

The upper inner wall surface material 20C is sandwiched and fixed between the upper middle inner wall surface material 20B and the upper runner 50, so that the lower runner 10, the upper runner 50, and the spacer fixed to the outer wall base material 3 are fixed. The horizontal joint 40 connected to 8 fixes the lower inner wall surface material 20A, the intermediate inner wall surface material 20B, and the upper inner wall surface material 20C in a vertically aligned posture.

FIG. 11 is a perspective view of the wall structure before mounting the vertical joints as viewed from the indoor side. As shown in FIG. 11, the inner wall surface material unit 20 is formed by the lower inner wall surface material 20A, the intermediate inner wall surface material 20B, and the upper inner wall surface material 20C. The above is the inner wall surface material unit forming step in the construction method according to the embodiment.

By repeatedly executing the inner wall surface material unit forming step two or more times, as shown in FIG. 11, a plurality of inner wall surface material units 20 are arranged side by side in the horizontal direction on the indoor side of the temporary building. Windows will be provided at various points on the wall, but the illustration will be omitted.

Next, with reference to FIG. 12, vertical joints inserted between the adjacent inner wall surface material units 20 will be described. The illustrated vertical joint 60 has a support piece 61 and an insertion piece 62 extending from the support piece 61 and inserted between adjacent inner wall surface material units. Further, the insertion piece 62 has an unevenness 63 that engages with the end surface of the inner wall surface material 20 on the left and right side surfaces on the tip end side thereof.

As shown in FIG. 11, the wall of the temporary building shown in FIG. 13 is attached by inserting the vertical joint 60 shown in FIG. 12 from the insertion piece 62 between the adjacent inner wall surface material units 20. The structure 100 is constructed. As shown in FIG. 13, the support piece 61 is exposed to the indoor side and supports the left and right inner wall surface material units 20 from the indoor side.

FIG. 14 is a cross-sectional view taken in the middle of the lower inner wall surface material in the area where the vertical joints are arranged. As shown in FIG. 14, the left and right unevenness 63 of the insertion piece 62 is inserted by engaging with the end faces of the left and right inner wall material units 20 (in FIG. 14, the lower inner wall material 20A is shown). The left and right inner wall surface material units 20 can be supported from the indoor side without the vertical joints 60 being disengaged from the left and right inner wall surface material units 20. That is, the vertical joints 60 can prevent the individual inner wall surface materials 20A, 20B, and 20C forming the inner wall surface material unit 20 from coming off the unit.

FIG. 15 is a cross-sectional view seen from above the horizontal joints above the lower inner wall surface material in the area where the vertical joints are arranged. As shown in FIG. 15, the horizontal joint 40 extending in the horizontal direction is edge-cut near the core of the outer wall column 2, and as shown in the figure, has a slight gap G between the end faces thereof. The vertical joint 60 attached at the end of construction is inserted between the inner wall surface material units 20 that are in close contact with each other as shown in FIG. 14 in the cross section without the horizontal joint 40, and is shown in FIG. 15 in the cross section with the horizontal joint 40. It is inserted between the gaps G as shown above. As described above, when the vertical joint 60 is inserted, the already installed horizontal joint 40 and the post-constructed vertical joint 60 do not interfere with each other.

According to the illustrated construction method, the wall structure 100 can be constructed with good workability while eliminating the need to attach the inner wall base material of the temporary building having the conventional structure. Then, when the service period of the temporary building is over and the temporary building is dismantled, the dismantling is performed in the reverse order of the order in which the wall structure 100 is constructed, so that each component is not damaged and is therefore reused. Dismantling can be done in the possible state.

The temporary building having the wall structure 100 shown in the figure is not only a temporary housing with a relatively short service period, a temporary accommodation facility, etc., but also a general building such as a machine room provided in the basement or roof of the building. Includes residential facilities. Since the wall structure 100 has the inner wall surface materials 20A, 20B, and 20C made of glass wool board, the temporary building becomes a temporary building having not only heat insulating properties but also sound absorbing properties. Therefore, in addition to temporary living facilities, it is suitably used for temporary conference rooms and the like where both heat insulation and sound leakage prevention are required.

It should be noted that the configuration or the like described in the above embodiment may be another embodiment in which other components are combined, and the present invention is not limited to the configuration shown here. .. This point can be changed without departing from the spirit of the present invention, and can be appropriately determined according to the application form thereof.

For example, in the wall structure 100 of the temporary building in the illustrated example, the inner wall surface material unit 20 has a lower inner wall surface material 20A, an intermediate inner wall surface material 20B, and an upper inner wall surface material 20C. The inner wall surface material unit 20 may have only the lower inner wall surface material 20A and the upper inner wall surface material 20C. Further, although the wall structure 100 of the temporary building in the illustrated example has vertical joints 60, it may be a wall structure of a temporary building (state shown in FIG. 11) that does not have vertical joints 60.
