Description

Description: TECHNICAL FIELD The present invention relates to a mounting structure suitable for laterally covering a hard wall material.

[Conventional technology and problems]

Conventionally, hard wall materials are attached with metal fittings with a substantially H-shaped cross section,
Mounting holes are drilled in the hard wall material, or mounting holes are drilled at the time of manufacture, and nails are punched into these mounting holes and attached to the skeleton. However, when using metal fittings, it is only a structure to hold down,
When drilling a mounting hole on site with a drill, the hard wall material is often broken or damaged, which is inefficient. In addition, the hard wall material having the mounting holes drilled at the time of manufacture has a small thickness at a portion to be nailed and is made of a brittle material, so that the hard wall material is erroneously damaged at the time of driving with a hammer. There were many things. Needless to say, nailing required skill.

[Means for solving the problem]

In order to eliminate such a drawback, the present invention forms an integral fitting by fitting a mounting bracket to the rear surface of the upper end of the hard wall material,
By forming the U-shaped locking groove formed in the fixing part of the mounting bracket so as to contact the lower surface of the male part at the upper end, the male part side of the hard wall material is fixed by fixing the mounting bracket to the frame The female portion serving as the lower end provides a locking piece serving as an upper edge of the locking groove of the mounting bracket, and a mounting structure of a hard wall material fitted and integrated with the male portion.

〔Example〕

Hereinafter, an embodiment of a mounting structure for a hard wall material according to the present invention will be described in detail with reference to the drawings. FIG. 1 shows a typical example of the mounting structure of the hard wall material, where A is a hard wall material (hereinafter simply referred to as a wall material), B is a mounting bracket, α is a skeleton, and β is a fixing tool. . More specifically, the wall material A is mainly made of at least one of porcelain stone, feldspar, clay, kaolin and the like, and if necessary, cement, asbestos, silica, glass fiber, carbon fiber, whisker. The raw soil mixed with steel fiber, slag, and various aggregates is formed into a long shape by extrusion or formed by pressing and then baked at a predetermined temperature, or various aggregates and fibrous materials in cement (Glass fiber, carbon fiber, mineral fiber, etc., long fiber or short fiber, etc.) mixed, impregnated, extruded, formed by a papermaking method, steam-cured, and formed, for example, as shown in FIG. 2, or After being formed into a plate by the above method, it is formed by cutting as shown in FIG. That is, the wall material A is plate-shaped, and has a male portion 4 protruding in a convex shape on one of both side ends of the decorative surface portion 1 and a female portion 5 concaved inward on the other side. The back surface 3 has an engaging portion 6 recessed in a dovetail shape along the longitudinal direction. More specifically, the male portion 4 connects the wall members A to each other by being inserted into the female portion 5 and a locking piece 12 of a mounting bracket B described later, and the engaging portion 6 is formed in a dovetail shape. This is for fixing a mounting bracket B, which will be described later, to the back surface 3 of the wall material A, and includes an insertion groove 7 recessed in the male part 4 direction and an engagement groove 8 recessed in the female part 5 direction. is there. The mounting bracket B is a long body or a short body, and is formed by pressing and rolling a metal plate or extruding a metal material or a plastic material. As shown in FIG. A fixing portion 9 comprising a fixing piece 11 having one end edge of the stabilizing piece 10 extending inward, a locking piece 12 formed by bending the tip of the fixing piece 11 into a substantially U-shape, and a locking groove 13. And an insertion groove 14 in which the other end of the fixing piece 10 is bent in a U-shape, and an insertion groove 14
Support piece 15 with upper edge bent outward in inverted U shape and extended
An insertion piece 16 formed in a substantially inverted U-shape in cross section from the upper edge of the insertion groove 14 and the support piece 15, and a fitting piece 17 formed by inverting the tip of the support piece 15 downward. It is formed from the fitting portion 18 . As shown in FIG. 4, the mounting piece is inserted by inserting the insertion piece 16 of the mounting bracket B into the insertion groove 7 of the wall material A, and then pressing the fitting piece 17 of the mounting bracket B into the engaging groove 8. The wall material A and the mounting bracket B are integrated with each other. The wall material A and the mounting bracket B are integrated with each other. The engagement between the groove 7 and the insertion piece 16 is further strengthened by the weight of the wall material A. The locking piece 12 of the fixing part 9 is formed so as to be in contact with the lower edge of the male part 4 and not to protrude outward from the tip of the male part 4. Further, as shown in FIG. 1, the fixing piece 11 is a part for fixing the mounting bracket B to the frame body α by a fixing tool β such as a nail.
Is fixed to the skeleton α.

Here, the dimensional relationship of each part will be briefly described.
In the wall material A, the thickness of the male portion 4 is h ₁ , the height from the lower surface of the male portion 4 to the back surface of the wall material A is h ₂ , the opening height of the female portion 5 is h ₃ ,
The thickness of the lower edge 5a of the female part 5 is h ₄ , the protrusion length of the male part 4 is l ₁ , the length from the tip of the lower edge 7a of the insertion groove 7 to the side face 4a is l ₂ , and the lower edge 7a
The length from the tip to the tip of the male part 4 is l ₃ , the depth of the insertion groove 7 is l ₄ , the width of the engagement part 6 is l ₅ , the length of the lower edge 5a is l ₆ , The opening height of the locking groove 13 is h ₅ , the length of the locking piece 12 is l ₇ , the length from the tip of the insertion piece 16 to the locking groove 13 is l ₈ , and the depth of the insertion groove 14 is l ₉ If the width of the fitting portion 18 is l ₁₀ , the length from the innermost part of the insertion groove 14 to the tip of the locking piece 12 is l ₁₁ , and the plate thickness is t, h ₁ + t <h ₃ , h ₂ > h ₅ > h ₄ , l ₁ ≒ l ₆ + l ₄ , l ₂ <l ₈ ,

〔The invention's effect〕

As described above, according to the mounting structure for a hard wall material according to the present invention, the nail is not directly used for fixing the wall material, so that the wall material can be prevented from being damaged by driving the nail. Construction is easy because of the drop-in structure. Since the mounting bracket is mounted on the back surface of the wall material by fitting, the mounting bracket is not seen from the wall surface. The male part is fixed to the skeleton by the fitting part of the mounting bracket and is also fixed from the female part engaged with the locking piece of the mounting bracket, so that it does not peel off due to an earthquake or the like. There are effects and features such as.
