Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wall base material when a board is attached to a building wall such as a house or a condominium, and particularly relates to an under-wall base material that does not cause distortion of the board even when pressed and improves the stability of the board.

[0002]

[Prior Art]

 As this kind of wall base material, conventionally, a heat insulating material such as polyurethane foam is sprayed on the wall surface of a building, and a plurality of spacers are pierced through the heat insulating material on the wall surface with an adhesive, screws, etc. It is known that the inner wall is usually formed by attaching a board such as an interior material to the tips of the plurality of spacers.

[0003]

[Problems to be solved by the device]

 However, since the board is stuck on the tip of the spacer in the wall base material having the above-mentioned configuration, the spacer causes point contact, and when the board is pressed, the board is distorted and the stability of the board is poor. It is a thing.

Therefore, the purpose of the present invention is to make line or surface contact instead of the above-mentioned point contact when sticking the board, thereby improving the stability of the board without causing the board to warp even when pressed. It is an object of the present invention to provide a wall base material which has improved the above-mentioned drawbacks existing in the prior art.

[0005]

[Means for solving problems]

 In order to achieve the above-mentioned object, according to the present invention, a heat insulating material adhered to a wall surface of a building, a plurality of cap nuts protruding from the wall surface through the heat insulating material, and the cap nuts are provided. It consists of a screw bolt that is screwed and has a flat head portion, and a plate material that is attached to the flat plate of the screw bolt head across a plurality of these bolt nuts, and is screwed to the cap nut. The threaded bolt acts as a spacer between the wall surface and the plate shape.

[0006]

[Action]

 In the above-mentioned wall base material according to the present invention, since the plate material is attached to the flat plate of the head of the screw bolt over these plural pieces, the board attached on this is attached by the line contact or the surface contact with the plate material. Unlike the case where it is attached by the point contact with the tip of the spacer as described above, therefore, the board is not distorted even when pressed by the board and is stabilized.

【Example】

 Hereinafter, the present invention will be described with reference to the accompanying drawings. FIG. 1 is a sectional view of a concrete example of the wall underlayer material according to the present invention, FIG. 2 is a partial sectional view of another concrete example of the wall underlayer material according to the present invention, and FIG. 3 is shown in FIG. FIG. 4 is an exploded perspective view of a spacer used, FIGS. 4 to 7 are manufacturing process diagrams of a wall base material according to the present invention, and FIG. 8 is a front view of a wall surface completed using the wall base material of the present invention. Indicates.

In FIG. 1, reference numeral 1 is a concrete wall of a building such as a condominium, and a heat insulating material 3 such as polyurethane foam is sprayed onto the wall surface 2 to a desired thickness. Next, a plurality of cap nuts 4 are projected from the wall surface 2 so as to penetrate the heat insulating material 3.

As shown in FIG. 3, the cap nut 4 has a base 5 at its tip, and is protruded from the wall surface 2 by adhering the base 5 to the wall surface 2 with an adhesive or the like. This type of cap nut 4 is preferably made of a plastic material such as polyvinyl chloride or polystyrene, rather than being made of metal, from the viewpoint of the heat insulating effect. A screw bolt 7 whose head is formed in a flat plate 6 is screwed into the cap nut 4, and the cap nut 4 and the screw bolt 7 form a spacer 8.

The present invention is characterized in that a plate material 9 is further attached onto the flat plate 6 of the screw bolt 7 described above. The plate member 9 is a double bar having a substantially "C" -shaped cross section as shown in FIGS. 1 and 3, for example. In this case, the double bar 9 is supported upright by being fitted into the runner 10 at the lower end, and a plurality of flat plates 6 of the screw bolts 7 are inserted into the inside of the cross-section “C” shape so that the plurality of flat bars 6 can be placed on the flat plate 6. The pieces are attached to each other in the vertical direction or in the horizontal direction (not shown). Further, as shown in FIG. 2, the plate material 9 may be an elongated strip-shaped wood plate. In this case, the wooden board 9 is attached to the flat plate 6 by a nail 11 as shown in FIG. As a result, the spacer 8 acts as a spacer between the wall surface 2 and the plate member 9.

In the wall base material A according to the present invention configured as described above, the board 11 such as an interior material is attached to the plate material 9 with an adhesive, screws or the like to form the inner wall surface 12.

Hereinafter, a manufacturing process of the wall base material A according to the present invention will be described in detail with reference to FIGS. 4 to 7. First, as shown in FIG. 4, the base 5 portion of the cap nut 4 is bonded onto the wall surface 2 of the concrete wall 1 by using an adhesive. Next, as shown in FIG. 5, a heat insulating material 3 such as polyurethane foam is sprayed on the wall surface 2 to have a desired thickness. At this time, the lower end of the cap nut 4 and the base 5 are filled with the heat insulating material 3. Further, as shown in FIG. 6, the tip of the screw bolt 7 is inserted into the cap nut 4 and screwed. Next, as shown in FIG. 7, the plate material 9 is attached to the flat plates 6, 6 ... The wall base material A is formed.

A board 12 is attached to the plate material 9 of the wall base material A thus configured to form the inner wall surface 13 shown in FIG.

[0014]

[Effect of the device]

 As described above, the wall base material of the present invention has line or surface contact instead of the point contact as in the past when sticking the board, so that the board is not distorted even when pressed and the stability of the board is improved. This is a useful idea.
