Summary of the Invention

Problem to be Solved by the Invention

[0005] However, the above-mentioned conventional sound insulation wall construction method is a construction method of adding a functional plate material such as a sound absorbing material to the surface of a wall, and therefore has a disadvantage that the design of the original wall is hidden. In addition, operations such as nailing, bonding, and baseboard installation for attaching the functional plate material to the wall surface are required, which also has a disadvantage that the cost required for post-construction increases.

[0006] In view of the above circumstances, an object of the present invention is to provide a wall structure and a post-construction method thereof that do not hide the design of the original wall and can easily change or additionally construct sound absorption performance and heat insulation performance.

Means for Solving the Problem

[0007] To solve the above-mentioned problems, the wall structure of this invention is a wall structure consisting of a pair of opposing wall surfaces, wherein a space is formed between one wall surface and the other wall surface, allowing for the insertion and installation of a plate-like body, and an opening is formed at the end of the wall structure, which serves as an entrance for inserting the plate-like body into the space.

[0008] With the above configuration, sound absorption or heat insulation properties can be added to the original wall by inserting sound-absorbing or heat-insulating material as a plate-like body into the space formed between the wall surface on one side and the wall surface on the other side. Alternatively, the sound absorption or heat insulation properties can be changed by replacing the plate-like body that was placed in the space. In other words, since the plate-like body is inserted into the space rather than being attached to the surface of the original wall, the design of the original wall is not hidden. Furthermore, since the plate-like body is inserted into the space from the opening at the end of the wall structure, post-installation of the plate-like body into the space is also easy.

[0009] The extension direction of the above-mentioned space and the insertion direction of the plate-like body into the opening may be parallel (referred to as the first embodiment in this section). Alternatively, the extension direction of the above-mentioned space and the insertion direction of the plate-like body into the opening may intersect, and a curved introduction portion that curves toward the extension direction from the opening may be provided on the inner side of the opening (referred to as the second embodiment in this section).

[0010] A cover that opens and closes the opening may be attached to the opening. This would prevent the opening from being exposed.

[0011] A guide portion may be attached to the above-mentioned space to guide the movement of the plate-like body. This would allow the plate-like body to be smoothly inserted into the above-mentioned space.

[0012] Furthermore, the post-construction method for the wall structure of this invention is characterized by sequentially inserting a plurality of the plate-like bodies into the space, and fixing adjacent plate-like bodies to each other using fixing members that span the parts of adjacent plate-like bodies that are close to each other. This makes it possible to fix adjacent plate-like bodies to each other and integrate a plurality of the plate-like bodies.

[0013] Furthermore, the post-construction method for the wall structure of this invention is a post-construction method for inserting the plate-like bodies into the space in the wall structure, characterized in that support columns are placed between a plurality of plate-like bodies that are sequentially inserted into the space. According to this, even if the plate-like bodies are prone to falling over because they do not stand on their own, they can be stood upright by the support columns.

[0014] In the post-construction method of the wall structure described above, horizontal members may be attached between the support columns to receive the plate-like body. This allows the horizontal members to prevent the plate-like body from bulging outwards, even if it is not easily self-supporting and bulges outwards in the middle.

[0015] Furthermore, the post-construction method for the wall structure of the present invention is a post-construction method for inserting the plate-like body into the space in the wall structure of the first embodiment, wherein a plurality of the plate-like bodies are connected so as to be bent in one direction relative to the main surface of the plate-like body, the plurality of plate-like bodies are arranged so as to bend in one direction relative to the main surface of the plate-like body outside the opening so as to bend in one direction relative to the extension direction of the space, and the plate-like body to be inserted from the opening is bent in one direction outside the opening so as to bend in the direction of travel of the plate-like body to the extension direction of the space.

[0016] Further, the post-installation method for a wall structure according to the present invention is a post-installation method for inserting the plate-shaped body into the space portion in the wall structure of the second aspect, wherein the plurality of plate-shaped bodies are foldably connected to a main surface of the plate-shaped bodies, the plurality of plate-shaped bodies are arranged outside the opening such that an extended surface of the main surface intersects with an extending direction of the space portion, the orientation of the plate-shaped body to be inserted through the opening is changed by the curved introduction portion on the inner side of the opening, and the advancing direction of the target plate-shaped body is oriented toward the extending direction of the space portion. Effects of the Invention

[0017] According to the present invention, there is provided an effect that modification and additional construction of sound absorption performance and heat insulation performance can be easily performed without hiding the design of the original wall. Brief Description of the Drawings

[Figure 5] Fig. 5 is an explanatory view in a plan view showing a wall structure and a post-installation method according to a modified example of the embodiment. Mode for Carrying Out the Invention

[0019] Hereinafter, embodiments of the present invention will be described based on the attached drawings. As shown in Fig. 1 and Fig. 2, the wall structure 1 of the embodiment is arranged so as to partition an indoor space, and consists of a pair of back-to-back wall surface portions 2, 2. Each wall surface portion 2 includes a wall surface material 21 and a vertical crosspiece 22 that is a base member arranged on the back surface side of the wall surface material 21.

[0020] In the wall structure 1, a space portion S that allows insertion and installation of a plate-shaped body B is provided between a vertical rail 22 of a wall surface material 21 on one side and a vertical rail 22 of a wall surface material 21 on the other side. An opening 11 serving as an inlet for inserting the plate-shaped body B into the space portion S is formed on the open end side of the wall structure 1 (such as the side opposite to an outer wall). The plate-shaped body B is a heat-insulating performance plate, a sound-absorbing performance plate, a heat-insulating and sound-absorbing performance plate, or the like, which is formed of a foamed resin plate, or a plate-shaped member formed by placing glass wool or the like in a bag member.

[0021] The insertion direction of the plate-shaped body B in the opening 11 is parallel to the extending direction of the space portion S. Further, a cover portion 12 for opening and closing the opening 11 is attached to the opening 11. For example, one side of a hinge 12a is fixed with a screw to one side of the cover portion 12, and the other side of the hinge 12a is fixed with a screw to the wall surface material 21 on the one side.

[0022] Further, a guide portion 3 for guiding the movement of the plate-shaped body B is provided on the upper side (ceiling side) of the space portion S. The guide portion 3 is formed of, for example, a runner having a U-shaped cross section. Further, the guide portion 3 may be provided not only on the upper side of the space portion S but also on the lower side (floor side). Further, for example, as the plate-shaped body B, one having a concave groove formed on the central side of the upper surface thereof may be used, and as the guide portion 3, a rail member having a convex portion fitted into the concave groove may be used.

[0023] With such a wall structure 1, by inserting a sound absorber, a heat insulator, or the like as the plate-shaped body B into the space portion S formed between the wall surface portion 2 on the one side and the wall surface portion 2 on the other side, sound absorption performance, heat insulation performance, or the like can be added to the original wall. Alternatively, the sound absorption performance, heat insulation performance, or the like can be changed by replacing the plate-shaped body B that has been placed in the space portion S. That is, since the plate-shaped body B is inserted into the space portion S instead of a structure in which a plate material is attached to the surface of the original wall, the design of the original wall is not hidden. Further, when the guide portion 3 for guiding the movement of the plate-shaped body B is attached to the space portion S, the insertion of the plate-shaped body B into the space portion S can be smoothly performed.

[0024] Next, a post-construction method for wall structure 1, that is, a post-construction method for inserting plate-like bodies B into the space S of wall structure 1, will be described. In this post-construction method, multiple separate and independent plate-like bodies B can be sequentially inserted into the space S. However, in the example shown here, in order to improve construction efficiency, a connecting body is used in which multiple plate-like bodies B are connected so as to bend to one side relative to one main surface of the plate-like bodies B. Such a connecting body can be obtained by attaching a sheet material so as to span the entire main surface of the one main surface or span a part of the main surface.

[0025] The installer arranges multiple plate-like bodies B outside the opening 11, for example, on a corridor, so that the extended surfaces of their main faces intersect with the extending direction of the space S. The installer then folds the plate-like body B to be inserted into the opening 11 outside the opening 11, and pushes this plate-like body B into the space S with its direction of travel aligned with the extending direction of the space S. In this way, the post-installation of the plate-like bodies B into the space S is easy.

[0026] Furthermore, when inserting multiple plate-like bodies B into the space S in this manner, as shown in Figure 1, a fixing member 4 is placed across both edges of the adjacent main surfaces of the plate-like bodies B, and this fixing member 4 is attached to the plate-like bodies B with screws or the like, thereby fixing the adjacent plate-like bodies B to each other. This allows the adjacent plate-like bodies B to be fixed to each other and integrated into a single unit. If the plate-like bodies B are lightweight, such as sound-absorbing boards, they can be fixed to each other by attaching double-sided tape between the sides of adjacent plate-like bodies B.

[0027] Furthermore, when inserting multiple plate-like bodies B into the space S sequentially in this manner, as shown in Figure 3, a U-shaped fixing member 4A can be placed so as to straddle the upper surfaces of the adjacent edges of two adjacent plate-like bodies B, and this fixing member 4A can be attached to the plate-like bodies B using double-sided tape or screws to fix the adjacent plate-like bodies B together. This method also allows for the fixing of adjacent plate-like bodies B together and the integration of multiple plate-like bodies B into a single unit. Note that a runner smaller in size than the runner used as the guide part 3 can be used as the fixing member 4A. Alternatively, the U-shaped fixing member 4A may be placed so as to straddle the lower surfaces of the adjacent edges of two adjacent plate-like bodies B, or both upper-surface-placed and lower-surface-placed fixing members 4A may be used.

[0028] Furthermore, as shown in Figure 4, support columns P may be placed between multiple plate-like bodies B that are sequentially inserted into the space S, to support the sides of the plate-like bodies B. The support columns P are made of, for example, wooden lumber. The sides of the plate-like bodies B are fixed to the support columns P using, for example, double-sided tape or the fixing member 4 mentioned above. This allows the plate-like bodies B to stand upright even if they are not easily self-supporting and would otherwise fall over, thanks to the support columns P. The multiple plate-like bodies B used here are not separate and independent of each other, but sheets can also be attached so as to span the main surfaces of the multiple plate-like bodies B and the support columns P, and these can be connected in a way that allows them to be folded in one direction.

[0029] Furthermore, a horizontal member H may be attached between the support columns P to support the upper and lower middle section of the plate-like body B. This allows the plate-like body B to be easily inserted even if it is not self-supporting and tends to bulge in the middle, by using the horizontal member H to prevent this bulging. The horizontal member H can be made of wood or the like, and screws or the like can be used to fix it to the support columns P.

[0030] Figure 5 shows a modified example of wall structure 1, called wall structure 1A. In wall structure 1A, the extension direction of the space S intersects with the insertion direction of the plate-like body B in the opening 11, and a curved introduction section 5 is provided on the back side of the opening 11, which curves from the opening 11 toward the extension direction. The curved introduction section 5 is made of, for example, a flexible resin plate, and both edges are fixed to the vertical battens 22 with screws or the like.

[0031] Even in the post-construction method for the wall structure 1A, a connecting body can be used in which multiple plate-like bodies B are connected so as to bend to one side relative to the main surface of one of the plate-like bodies B. The constructor arranges the multiple plate-like bodies B outside the opening 11 so that the extended surface of the main surface intersects with the extension direction of the space, and changes the orientation of the plate-like body B to be inserted from the opening using the curved introduction section 5 at the back of the opening 11, so that the direction of travel of the plate-like body B is directed toward the extension direction of the space S.

[0032] Although embodiments of this invention have been described above with reference to the drawings, this invention is not limited to the illustrated embodiments. Various modifications and variations can be made to the illustrated embodiments within the same scope as this invention, or within the equivalent scope. [Explanation of symbols]
