Description

  The present invention relates to a wall structure of a temporary building.

  Temporary buildings are provided for various uses such as temporary arena for outdoor events, temporary housing that requires urgent construction after the earthquake, and temporary accommodation facilities, and construction is also planned. Here, with reference to FIG. 1, an example of the wall structure of the conventional temporary building is demonstrated. FIG. 1 is a cross-sectional view of the wall structure of a conventional temporary building, and is a view of this cross-section (horizontal cross-section) as viewed from above.

  In the wall structure 20 of the temporary building shown in FIG. 1, the outer wall surface material 1 made of metal siding board, ceramic siding board, etc. is screwed to the outer wall column 2 made of light steel square steel pipe etc. Similarly, the inner wall surface material 6 is fixed to the outer wall pillar 2 and the inner wall surface material 6 is further fixed to the inner wall foundation material 4 made of a plurality of light-weight channel steels or the like to constitute the whole. The outer wall surface material 1 is fixed not only to the outer wall pillar 2 but also to an outer wall foundation material (stub) 3 made of light-weight channel steel or the like disposed between the outer wall pillars 2. The outer wall surface material 1 is attached to the right and left of the exterior side of the outer wall pillar 2 via, for example, a dry vertical joint 1a.

  In addition, a laterally extending plate 2a is welded to the side surface of the outer wall column 2, and a vertically extending attachment longitudinal edge made of light-weight grooved steel or the like is attached to the end in the width direction of the outer wall surface material 1 The outer wall material 1 is directly screwed to the outer wall pillar 2 and the mounting vertical shell edge 1b is bolted to the plate 2a so that the outer wall material 1 for the outer wall pillar 2 is screwed. Installation is planned. In addition, it can be called an outer wall panel including the outer wall surface material 1, the outer wall base material 3, and the attachment vertical trunk edge 1b.

  At the lower end and the upper end of the wall structure 20, a runner having a U-shaped cross section extending in the width direction of the outer wall material 1 is laid with the U-shaped opening facing the inner wall foundation 4 side. The inner wall foundation material 4 is fitted in and fixed to a runner having a U-shaped cross section located above and below. Of the upper and lower runners, the lower runner 5 is shown in FIG. The inner wall surface material 6 is fixed to the outer wall pillar 2 and is fixed to a plurality of inner wall foundation 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 foundation material 3 are generally different from each other, and more specifically, the dimension t1 of the outer wall pillar 2 is The inner wall surface material 6 can not be fixed on the indoor side surface of both the outer wall pillar 2 and the outer wall foundation material 3 because it is generally relatively large. Therefore, in the conventional wall structure 20, a configuration is adopted in which the inner wall surface material 6 is fixed to the outer wall column 2, and is fixed by a plurality of inner wall foundation materials 4 disposed flush with the indoor side surface of the outer wall column 2. ing.

  In addition, since gypsum board or caicaal plate (calcium silicate plate) is generally applied to the inner wall surface material 6, a finish material 6a such as cloth is generally provided on the surface of the inner wall surface material 6 on the indoor side. . In addition, since the inner wall surface material 6 is formed of gypsum board or the like, the heat insulating material 7 such as glass wool is filled in the wall space between the outer wall surface material 1 and the inner wall surface material 6 to insulate the temporary building Is guaranteed.

  As described above, in the wall structure 20 of the conventional temporary building, a plurality of inner wall foundation materials 4 for fixing the inner wall material 6 and runners (the lower runners 5 are shown in FIG. 1) for supporting them vertically are essential Although it is a temporary building, there is a problem that the number of parts (in particular, the number of parts of lightweight steel) increases when the wall structure 20 is formed. And, even though it is a temporary building with a relatively short service period, the inner wall surface material 6 is firmly fixed to the outer wall pillar 2 and the inner wall foundation material 4 with a screw or the like. Needs to be addressed.

  In addition, it is necessary to provide finish material 6 a on the surface of inner wall surface material 6, and furthermore, it is necessary to fill heat insulating material 7 in the wall space between outer wall surface material 1 and inner wall surface material 6. There is also a problem that the number of construction steps is increased due to the installation, the installation of the inner wall foundation 4 and the installation of the heat insulating material 7.

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

Japanese Utility Model Application Publication No. 5-54707

  However, even if the sound-absorbing and heat-insulating material fixture described in Patent Document 1 is applied to the wall structure of a conventional temporary building, a plurality of inner wall foundation materials for fixing the inner wall surface material and a runner supporting these materials vertically The installation can not be canceled, and the problem that the number of parts is large in the wall structure of the temporary building or the problem that the number of construction steps is large can not be solved.

  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 in which attachment of at least an inner wall foundation material and a runner supporting the same is unnecessary.

In order to achieve the above object, one aspect of the wall structure of the temporary building according to the present invention is:
A plurality of outer wall pillars arranged at predetermined intervals;
An outer wall material fixed to the plurality of outer wall columns;
An outer wall foundation material disposed between the outer wall columns and fixing the outer wall surface material, the outer wall foundation material having a lower height in a horizontal cross section than the outer wall columns;
A spacer is attached to the indoor side of the outer wall base material,
An inner wall surface material is attached to the outer wall pillar and the spacer.

  According to this aspect, the inner wall base material and the runner supporting the upper and lower portions are unnecessary, and the height of the horizontal cross section of the outer wall pillar and the outer wall base material whose inner side faces are not flush with each other is low (the outer wall surface By attaching a spacer to the indoor side surface of the outer wall foundation material (small in dimension from the material to the inner wall surface material), the inner wall surface material can be fixed to the outer wall pillar and the outer wall foundation material. In addition to temporary buildings with relatively short service periods such as temporary housing and temporary arena, temporary buildings with the wall structure of this aspect may be used for general buildings such as machine rooms provided in the basement or rooftop of buildings etc. It includes non-residential facilities that accompany the rooms.

  Further, in another aspect of the wall structure of the temporary building according to the present invention, a joiner is attached to an indoor side surface of the outer wall column, and the inner wall surface material is fixed to two adjacent joiners spaced apart from each other. It is characterized by

  According to this aspect, the inner wall material for the outer wall pillar (and the spacer fixed to the outer wall foundation material) is fixed by, for example, inserting and fixing the inner wall material to the joiner attached to the indoor side surface of the outer wall pillar Installation can be done smoothly. In addition, as a joiner in which the inner wall surface material can be fitted in this way, one having a cross section in the shape of a letter "U" or a letter "U" is preferable.

  In another aspect of the wall structure of the temporary building according to the present invention, the spacer comprises a piece-like spacer, and the piece-like spacer is attached to the upper region, central region and lower region of the outer wall foundation material. It is characterized by

  According to this aspect, since the spacer is a piece-like (block-like) spacer, in the case where a brace or the like is disposed in the wall space between the outer wall surface material and the inner wall surface material, for example, A piece-like spacer can be disposed at a position that does not interfere. In addition, one or more piece-like spacers are provided in each of the outer wall foundation materials at least in the upper area, the central area, and the lower area of the outer wall base material, so that the inner wall surface material is reinforced with a plurality of piece-like spacers. It can be fixed to

  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 surface material made of glass wool board, the inner wall surface material itself has the heat insulating performance, and accordingly, the wall space between the outer wall surface material and the inner wall surface 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 a glass wool board having a glass cloth finish, the application of a surface finish material like a gypsum board can be made unnecessary. From these things, a construction process can be reduced compared with the wall structure of the conventional temporary building, and the wall structure excellent in heat insulation can be provided although it is simple.

  As can be understood from the above description, according to the wall structure of the temporary building of the present invention, at least the attachment of the inner wall foundation material and the runner for supporting the same can be eliminated.

It is a cross-sectional view of an example of the wall structure of the conventional temporary building. It is a cross-sectional view of an example of the wall structure of the temporary building which concerns on embodiment of this invention. It is a perspective view of an example of wall structure of a temporary building concerning an embodiment of the present invention, and is a figure which fractured a part of inner wall surface material so that an inside of wall structure could be recognized visually.

  Hereinafter, a wall structure of a temporary building according to an embodiment of the present invention will be described with reference to the attached drawings. In the present specification and the drawings, substantially the same components may be denoted by the same reference numerals and redundant description may be omitted.

[Wall structure of temporary building according to the embodiment]
With reference to FIG.2, 3, an example of the wall structure of the temporary building which concerns on embodiment is demonstrated. Here, FIG. 2 is a cross-sectional view of an example of the wall structure of a temporary building according to the embodiment of the present invention, the cross-section being viewed from above, and FIG. 3 is a perspective view thereof. 6 is a partially broken view of the inner wall surface material so that the inside of the wall structure can be seen.

  The wall structure 30 of the temporary building shown in FIG. 2 will be described in comparison with the wall structure 20 of the conventional temporary building shown in FIG. 1 described above. In the wall structure 30, the outer wall material 1 is fixed with screws or the like to the outer wall column 2 made of a light steel steel square steel pipe or the like and the plurality of outer wall foundation materials 3 made of light grooved steel etc. Similar to structure 20. The outer wall surface material 1 is formed of a metal-based siding board, a ceramic-based siding board or the like, but from the viewpoint of constructing the wall structure 30 of the temporary building, the metal-based siding board is as light as possible and excellent in workability. Is preferably applied.

  In FIG. 2, the dimensions t1 and t2 in the wall thickness direction from the outer wall surface material 1 to the inner wall surface material 10 in the outer wall pillar 2 and the outer wall foundation material 3 are different from each other, and the dimension t1 of the outer wall pillar 2 is relative Is getting bigger. A piece-like spacer 8 is fixed to the indoor side surface of the outer wall foundation material 3 having a relatively small dimension in the wall thickness direction from the outer wall surface material 1 to the inner wall surface material 10. The piece-like spacer 8 is, for example, a cubic spacer as shown in FIG. As shown in FIG. 2, the dimension of the piece-like spacer 8 in the wall thickness direction is t3, and the dimension t2 of the outer wall foundation material 3 and the dimension t3 of the piece-like spacer 8 is the dimension t1 of the outer wall post 2 The respective dimensions t1 to t3 are set so as to be the same as or substantially the same as the above.

  Here, the piece-like spacer 8 is made of a resin foam and is excellent in cutting processability because of the resin foam, and since it is a foam, the piece-like spacer 8 itself can also contribute to the heat insulation of the wall structure 30 . As this resin foam, Neoma home (registered trademark) manufactured by Asahi Kasei Building Materials Co., Ltd. can be used, for example. The piece-like spacer 8 can be fixed to the indoor side surface of the outer wall foundation material 3 with an adhesive, an adhesive tape, or the like. In addition, an engagement portion (not shown) (for example, a groove having a cross section similar to that of the outer wall foundation 3 and having the opening of the groove directed to the indoor side) is provided on the indoor side surface of the outer wall foundation 3 The piece-like spacer 8 may be fitted into and fixed to the engaging portion.

  On the other hand, on the indoor side surface of the outer wall pillar 2, a joiner 9 having a V-shaped cross section is fixed by an adhesive, an adhesive tape, a screw or the like. As shown in FIG. 2, the inner wall surface material 10 is fixed to the joiners 9 of the two adjacent outer wall pillars 2 at intervals by being fitted. In the fixed posture of the inner wall surface material 10, both ends of the inner wall surface material 10 are fitted and fixed to the joiner 9 and contact with the plurality of spacers 8 in the middle position, for example, a state where the spacer 8 is slightly pressed It is fixed by.

  Thus, in the fixed structure of the inner wall surface material 10 shown in FIG. 2, the inner wall base material 4 shown in FIG. 1 and the runner supporting the upper and lower portions can be eliminated, and like fixing to the inner wall base material 4. The inner wall surface material 10 only needs to be in surface contact without being screwed to the spacer 8. Therefore, the mountability of the inner wall material 10 to the outer wall pillar 2 (the joiner 9 fixed thereto) is much better than that of the conventional wall structure 20, and fasteners such as screws can be significantly reduced.

  However, considering that the target of the wall structure 30 is a temporary building whose operation period is relatively short and assembly and disassembly are preferably performed in a short time, the inner wall material 6 is screwed like the conventional wall structure 20. It is not always necessary to firmly hold the outer wall pillar 2 and the inner wall foundation 4 firmly. Therefore, like the wall structure 30 shown, the configuration in which the inner wall surface material 10 is fitted and fixed to the joiner 9 can be said to be a suitable configuration for a temporary building.

  Further, in the wall structure 30, glass wool board is applied to the inner wall surface material 10. Here, as the glass wool board to be applied, for example, Aclear GC or the like of Aclear (registered trademark) series manufactured by Asahi Fiber Glass Co., Ltd. can be applied.

  By applying the glass wool board to the inner wall surface material 10, the inner wall surface material 10 itself has the heat insulating performance, and accordingly, in the wall space between the outer wall surface material 1 and the inner wall surface material 10, the wall structure shown in FIG. It is unnecessary to fill the heat insulating material 7 as in No. 20. Further, since the inner wall surface material 10 is a glass wool board having a glass cloth finish, the application of the surface finish material can be made unnecessary as in the case of the gypsum board which is the inner wall surface material 6 of the wall structure 20 shown in FIG.

  From these things, in the wall structure 30 which has the inner wall surface material 10 which consists of glass wool board, a construction process can be reduced compared with the wall structure 20 of the conventional temporary building, and comparing FIG. As is apparent, the wall structure 30 is a wall structure with excellent thermal insulation while having a simple internal structure of the wall structure. With respect to the reduction of the installation process, the wall structure 30 does not include the inner wall foundation material 4 and the heat insulating material 7 compared to the conventional wall structure 20, so the wall structure is not only assembled when the wall structure 30 is assembled. The same effect is achieved at the time of dismantling of 30.

  As shown in FIG. 3, in the wall structure 30 of the temporary building, piece-like spacers 8 are respectively attached to the upper region, the central region, and the lower region of the outer wall foundation material 3. Thus, when the brace 11 made of, for example, a round steel or the like is disposed in the wall structure as shown in FIG. 3 by applying the piece-like spacer 8, the interference of the brace 11 and the spacer 8 is It can be eliminated. Then, while eliminating the interference with the braces 11 in this manner, one or more spacers 8 in each of the three regions of the outer wall foundation material 3 contact the inner wall surface material 10, and the entire area of the inner wall surface material 10 is It can be supported from the inside of the wall structure 30. In addition, although illustration is abbreviate | omitted, ensuring of the electrical system in a temporary building can be aimed at by attaching the molding material which lets an electrical wiring etc. pass on the indoor side surface of the joiner 9 facing indoor side.

  The temporary building with the wall structure 30 shown in the figure is not only temporary housing with a relatively short service period, temporary accommodation facilities, etc., but also non-general buildings such as machine rooms provided in the basement or roof of buildings etc. It also includes residential facilities. Since the wall structure 30 has the inner wall surface material 10 made of glass wool board, the temporary building becomes a temporary building having not only heat insulation but also sound absorption. Therefore, it is suitably used for a temporary meeting room etc. in which both heat insulation and a sound echo suppression effect are desired other than temporary residence facilities.

  In addition, there may be other embodiments in which other components are combined with the configuration etc. listed in the above embodiment etc., and the present invention is not limited to the configuration shown here at all. . In this regard, modifications can be made without departing from the spirit of the present invention, and can be appropriately determined according to the application form.
