BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hard wall material mounting structure in which male and female parts are substantially conical. More specifically, the present invention relates to a mounting structure for fixing a hard wall material directly to a wall base through a mounting tool without being driven by a fixing tool such as a nail.

[0002]

2. Description of the Related Art In general, hard wall materials, especially ceramic hard wall materials mainly made of cement, are commercially available on the market in which both male and female solid parts having a mating structure are formed on both side edges in the longitudinal direction. There is. And when these hard wall materials are fixed to the body, a method of drilling a mounting hole on the spot with a drill and driving a nail is usually adopted. Also, the actual exploitation Sho 62-131532
No. 2-23636, No. 2-36540, No. 2-36540 gazette, or mounting via a mounting tool.
No. 27148, and Japanese Utility Model Laid-Open No. 2-83939, a method of forming a fixing piece on a substrate and attaching it to the fixing piece is disclosed.

[0003]

However, when a hard wall material is directly fixed, the hard wall material is often destroyed by a drill, a hammer or the like when drilling or fixing with a nail. Yes, it was a construction problem. In addition, although the above-mentioned disadvantages have been eliminated in the above, there are problems such as an increase in the construction period, a problem of waterproofness, prevention of fire, and a problem of fire resistance in the above. Skill was required and there was a problem with waterproofness. Furthermore, if the hard wall material were destroyed after construction, it was very difficult to replace it.

[0004]

FIG. 1 is a sectional view for explaining the mounting structure, and FIGS. 2 and 3 show a hard wall material A and a mounting tool B used for this.

The hard wall material A is a cement board, a calcium carbonate board, a calcium silicate board, a ceramic board, a wood chip cement board, a magnesium carbonate board, or the like, or glass fiber, whiskers, aramid fiber, steel fiber, carbon fiber and various minerals. Extruded, press-molded, injection-molded, paper-formed, etc., mixed with fibers and various aggregates, or woven with various fibers in a cross shape, a three-dimensional shape,
It is impregnated with cement, clay, or the like, and molded into a panel shape by steam curing or firing, or a sandwich panel in which a thin metal plate and a synthetic resin foam are laminated, or a composite plate thereof.

To further explain, the hard wall material A has an elongated plate-like shape and has male and female parts 2 and 3 having a conical shape on both side edges in the width direction of the decorative surface 1 on the surface, as shown in FIG. In addition, the engaging groove 4 is formed in the notch corner of the female part 3 and the substantially recessed engaging groove 6 is formed in the substantially central part of the back surface 5. Further, in the figure, a hooking groove 7 formed in a substantially U shape in the locking groove 6 toward the male part 2 side, and a raw material saving inside the hard wall material A,
A plurality of hollow holes 8 are formed to reduce the self-weight.

The fixture B functions as a base and fixing material for the hard wall material A, and is mainly a color steel plate, an aluminum / zinc alloy plated steel plate, an aluminum plate, a titanium plate, a stainless steel plate, a copper plate, and a fluororesin-coated steel plate. A metal thin plate such as a clad steel plate, a laminated steel plate, or a vibration damping steel plate is roll-formed or press-formed, or an aluminum alloy or the like is extruded and formed into a long shape or a short shape.

As shown in FIG. 3, for example, the mounting portion 9 is substantially horizontal, and one end of the mounting portion 9 has a fitting groove 10 formed in a substantially U shape toward the inside. At the end, the insertion edge 11 that projects outward, the rising piece 12 that rises at a substantially right angle upward, and the tip of the rising piece 12 is bent inward and folded back outward again to form a substantially U-shape. The engaging piece 13 is formed from the engaging piece 13, and the pressing piece 14 is formed by extending the tip of the engaging piece 13. Further, a locking piece 15 is formed by projecting a position corresponding to the locking groove 6 of the hard wall material A in the middle of the mounting portion 9 upward. In addition, in the figure, the catching piece 1 in which the tip end of the supporting portion 16 and the locking piece 15 formed in a convex shape on both ends of the mounting portion 9 is bent toward the fitting groove 10 side
Forming 7.

To explain further, the mounting portion 9 is a portion for fixing the fixture B to the wall base α through the fixture β, and the fixtures B are inserted into the fitting groove 10 by inserting the insertion edge 11 in order. It is to connect. Also, the mounting portion 9 and the rising piece 1
2, the fitting groove 18 formed from the pressing piece 14 is a hard wall material A
The male solid portion 2 of the hard wall material A is inserted and the male solid portion 2 of the hard wall material A is pressed and fixed by the pressing piece 14. The hooking piece 17 of the locking piece 15 is inserted into the hooking groove 7 of the locking groove 6 and the engaging piece 13
Is to be engaged with and locked to the engaging groove 4, and both are for fixing the hard wall material A. The support portion 16 is a portion that is in close contact with the back surface 5 of the hard wall material A and supports the hard wall material A so as not to rattle.

[0019]

As described above, according to the structure for mounting a hard wall material according to the present invention, it is not necessary to directly drive a nail or to drill a mounting hole in the hard wall material. It is possible to prevent damage to the wall material. Since the fixture covers the wall underlayer, the wall body has good waterproofness and hermeticity.
Because the hard wall material is engaged with the fixture and fixed by pressing,
It can follow the deformation of the frame due to an earthquake and prevent damage and peeling. Since the disposition position of the hard wall material is determined by the mounting tool, it is not necessary to adjust the joints when the hard wall material is mounted, and the construction can be performed efficiently. Depending on the dimensional relationship between the hard wall material and the fixture, the hard wall material can be mounted after the fixture serving as the base and the fixing material is arranged on the entire surface of the body, and the construction rate can be further improved. At the same time, after the construction, if the hard wall material is damaged by an external impact, it can be easily replaced. As for the fixture for constructing the hard wall material, the dimension of the mounting base does not change due to the construction of the fixture, and since the hard wall material is a pair for one fixture, there is an error in the construction of the fixture. Only the joint width is rolled up, and the structure has improved mounting strength and workability. There are features and effects.
