  An architectural decoration material using a foamed resin as a core material is a lightweight material, and if it is relatively small, it can be stably fixed to a wall surface or the like of a building only with an adhesive. However, when it becomes large and has a certain weight, it is unstable with only the adhesive, and it is fixed to the building side using a fixing tool such as a nail or screw together with the adhesive, but in that case However, in order not to impair the surface design, it is necessary to perform an operation to make the head of the fixing tool that has been driven invisible from the outside by some means. Moreover, in any case, when there is unevenness on the ground, which is the mounting surface on the building side, it is not possible to sufficiently cope with it, and adhesion failure tends to occur.

  The present invention has been made in view of the circumstances as described above, and is a building decorative material that can be stably fixed to a building even if it is a large building decorative material having a certain weight. It is an object to disclose a mounting structure.

The mounting structure of the present invention for solving the above-mentioned problems is a structure in which a building decorative material having a core material made of foamed resin and coated on the surface with resin or mortar is attached to a building. The decorative material for use is one in which a part of the auxiliary material is inserted into the embedded groove formed in the core material on the upper edge and the lower edge of the back side , and the part is exposed and fixed together. An attachment jig that can be fixed to the auxiliary material is fixed to the building using a fixture, and the architectural decoration material is obtained by fixing the exposed portion of the attachment auxiliary material to the attachment jig. It is fixed to a building.

In a more specific aspect of the structure for attaching a decorative material for building to a building according to the present invention, the decorative material for building has a stepped portion on the back side, and the mounting auxiliary material partially includes the stepped portion. located in the exposed state, the fixture is fixed to the mounting aid member said exposed the mounting auxiliary member in a state superimposed on the portion of the. In this aspect, the stepped portion is preferably formed in the full width direction of the upper edge and the lower edge on the back side of the architectural decorative material, but may be partially formed.

  The structure for attaching a decorative material for building to a building according to the present invention is such that an attachment auxiliary material fixed to the back side of the decorative material for building and a mounting jig fixed to the building side are integrated by screwing or the like. The structure is connected and fixed, and an extremely stable fixing structure can be obtained by appropriately selecting the fixing location and the number of both of them. Therefore, even if it is large and heavy, it is not necessary to drive nails or the like into the building decorative material and fix it on the building side, so that the surface design of the building decorative material is not impaired. Moreover, since fixing with an adhesive is not required, even if unevenness occurs on the mounting surface on the building side, the mounting state is not affected thereby.

  In the structure for attaching a decorative material to a building according to the present invention, the attachment auxiliary material and the attachment jig may be made of any material provided that they have a required mechanical strength and can be screwed to each other. Can be made. For example, a resin material, a fiber reinforced resin material, a metal material, and the like can be given. As the resin material, a vinyl chloride resin, an acrylic resin, or the like is preferable. As the metal material, an aluminum material, a stainless material, or the like is preferable because it is resistant to corrosion.

  As an aspect of fixing the mounting auxiliary material to the back side of the decorative material for building, an embedded groove is formed in the core material in advance, and the mounting auxiliary material is inserted into the embedded groove in a partially exposed state to construct the building. A mode of integrating with a decorative material for use, or a mode of fixing and integrating a flat mounting auxiliary material at a required position of the core material with an adhesive. In the former mode, as the attachment auxiliary material, those having a cross-sectional shape such as an L shape, a C shape, and a bowl shape are preferably used.

  It is preferable that the length of the attachment auxiliary member and the attachment jig is substantially the same as the entire width of the decorative material for building because high attachment stability is obtained. However, when the required attachment stability is obtained, the length is long. You may make it fix using multiple short things.

  The attachment jig has at least a first surface fixed to a building and a second surface continuous to the first surface fixed to an attachment auxiliary member fixed to a building decorative material. The first surface is preferably a flat surface, and the second surface is preferably a surface having a shape that can be superimposed on the shape of the auxiliary mounting material fixed to the architectural decorative material.

Thereby, it is possible to hide the screw head from the outside and to prevent rainwater from entering between the back surface of the building decorative material and the wall surface of the building.

  According to the present invention, even a large decorative material having a certain weight can be fixed to a building in a stable state.

  Hereinafter, the present invention will be described based on embodiments with reference to the drawings. FIG. 1 is a cross-sectional view for explaining an embodiment of a structure for attaching a decorative material for building to a building according to the present invention together with its construction procedure.

  As shown in FIG. 1A, in this example, a building decorative material 10 includes a core material 11 that is, for example, a polystyrene-based foamed resin, and a coating 12 that is a resin, mortar, or the like that covers the surface side thereof. . On the upper edge and the lower edge on the back surface 13 side of the core material 11, step portions 14, 14 extending in the entire width direction are formed, and the step portions are not covered with the coating 12. L-shaped cut grooves 15 and 15 extending in the entire width direction are formed inside the core member 11 so as to be connected to the horizontal surfaces of the stepped portions 14 and 14. The stepped portion 14 and the cut groove 15 may be simultaneously formed at the time of foam molding of the core material, or may be post-processed after foam molding.

  A mounting aid 20 made of a stainless steel plate or the like and having an L-shaped cross section is inserted into the cut groove 15. The length of the attachment auxiliary member 20 is substantially equal to the lateral width of the core member 11. Further, the height of the vertical side 21 of the attachment auxiliary member 20 is substantially equal to the length of the vertical portion of the cut groove 15, and the horizontal width of the horizontal side 22 reaches the back surface 13 of the core material 11 beyond the horizontal portion of the cut groove 15. The width. Therefore, when the mounting auxiliary material 20 is inserted into the cut groove 15 formed in the core material 11, the mounting auxiliary material 20 is attached to the back surface 13 side of the building decorative material 10 (the core material 11) as shown in FIG. The posture is fixed to. In this state, a part of the fixed attachment auxiliary member 20, that is, a part of the horizontal side 22 thereof is exposed to the outside at the steps 14 and 14. For insertion, an adhesive may be applied to a required portion, and the attachment auxiliary material 20 may be fixed to the core material 11 using the adhesive.

  An attachment jig 30 made of a stainless steel plate or the like is fixed to the building 40 side to which the architectural decoration material 10 is to be attached. In this example, the length of the attachment jig 30 is substantially equal to the lateral width of the core member 11, and the first surface 31 fixed to the building 40 and the exposure of the attachment auxiliary member 20 fixed to the building decorative material 10. The second surface 32 is fixed to the horizontal side 22. The first surface 31 and the second surface 32 are continuous and have an L-shaped cross section as a whole. The first surface 31 is a flat surface, and the second surface 32 is a shape that can be superimposed on the exposed horizontal side 22 of the attachment auxiliary member 20 described above, that is, a flat surface in this example.

  A procedure for attaching the above-described architectural decoration material 10 to the building 40 will be described. First, as shown in FIG.1 (b), the upper and lower attachment auxiliary materials which fixed the two said attachment jigs 30 to the wall surface etc. of the building 40 at the back surface 13 side of the architectural decoration material 10 which it is going to attach. 20 and 20 are fixed in parallel with an interval that can be sandwiched from above and below. At the time of fixing, a fixing tool 33 such as a screw is driven into the first surface 31. Thereby, the second surface 32 of the mounting jig 30 protrudes from the wall surface of the building 40 in the vertical direction.

  In this state, the upper and lower mounting fixtures 20 and 20 are fixed to the wall surface, with the upper and lower mounting auxiliary materials 20 and 20 fixed on the rear surface 13 side facing the wall surface of the building 40 with the back surface 13 side of the building decorative material 10 facing. The building decorative material 10 is moved toward the wall surface of the building 30 so as to enter between the tools 30 and 30. When the horizontal portion 22 exposed to the outside of the mounting auxiliary member 20 and the second surface 32 of the mounting jig 30 fixed to the building 40 are superposed, a screw or the like is provided from the second surface 32 side. The second fixture 32 is driven in, and the second surface 32 and the horizontal portion 22 exposed to the outside are fixed together. Thereby, the decorative material for building 10 is fixed to the building 30 side in an extremely stable state. Finally, if necessary, the caulking material 35 is filled from the outside into the stepped portions 14 and 14 formed in the core material 11 after fixing.

  The above description is an explanation of one embodiment of the structure for attaching a building decorative material to a building according to the present invention, and the present invention is not limited to this. FIG. 2 is a diagram corresponding to FIG. In FIG. 2 (a), one attachment assisting material 20a is not a L-shaped cross section but a saddle-shaped cross section. In FIG.2 (b), the U-shaped thing of a cross section is used as both attachment auxiliary material 20b. In FIG.2 (c), the flat thing is used as one attachment auxiliary material 20c. Thus, the cross-sectional shape of the attachment auxiliary member 20 is arbitrary, and may be appropriately selected and used depending on the size and shape of the architectural decoration material 10 to be attached. Correspondingly, a cut groove 15 corresponding to the shape of the core material 11 is formed.

  In FIG. 2D, the step portion 14 is not formed on the core material 11, and a flat plate-like attachment auxiliary material 20 d is fixed to the upper and lower surfaces of the core material 11 using an adhesive. In this embodiment, it is not necessary to form the cut groove 15 in the core material 11. As shown in the drawing, when the decorative material for building 10 is small and lightweight, this form can be sufficiently dealt with. Moreover, it is not essential that the part of the exposed horizontal side 22 of the mounting auxiliary member 20 is a flat plate shape, and it may be a shape curved in cross section. In this case, however, the opposing surface of the core material 11 is also a curved surface having the same shape, and the second surface 32 of the attachment jig 30 is also a curved surface.
