DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure capable of easily installing and removing a hard wall material from a wall base without directly driving the hard wall material with a fixture such as a nail.

[0002]

2. Description of the Related Art Generally, many hard wall materials, particularly ceramic-based hard wall materials mainly made of cement, having a male part and a female part having a closed structure formed on both longitudinal edges. Have been. When these hard wall materials are fixed to a wall foundation, a method of drilling a mounting hole at the site with a drill and driving a nail, or a method of constructing through a mounting bracket is usually adopted.

[0003]

However, the work of drilling the mounting holes with a drill or fixing the hard wall material directly with nails requires skill and has a risk of damaging the hard wall material. In addition, the installation using the mounting bracket has a low mounting strength and cannot be removed after the installation.

The fixture A functions as a base and fixing material for the hard wall material B described later. For example, as shown in FIG. 2A, a color steel plate, an aluminum / zinc alloy-plated steel plate,
Rolled or pressed metal sheets such as aluminum sheets, titanium sheets, stainless steel sheets, copper sheets, fluororesin coated steel sheets, clad steel sheets, laminated steel sheets, vibration damping steel sheets, etc., or aluminum alloys, synthetic resin materials, etc. It is formed into a long shape by extrusion molding.

More specifically, the shape of the fixture A is such that a fixing portion 1 composed of a vertically flat mounting piece 2, a side wall 5 having an upper end of the fixing portion 1 bent inward, and a tip of the side wall 5 facing upward. A protruding bottom surface 6, a rotating groove 7 formed by the bottom surface 6 and the side wall 5, an upper side wall 8 in which the tip of the bottom surface 6 is bent outward, a running water portion 9 formed on the upper side wall 8 at a constant pitch, A fixing surface 10 whose tip is further projected upward, an engagement piece 11 whose tip of the upper wall 8 is projected upward, an engagement piece 11 and the upper wall 8
A female connecting portion 3 formed by an engaging groove 12 formed from the above, a pressing piece 13 having the tip of the upper side wall 8 hanging downward, an insertion groove 14 formed by the pressing piece 13 and the installation piece 2, and a fixing portion. 1, a lower wall 15 protruding inward from a lower end, a fixing piece 16 having a tip of the lower wall 15 hanging downward, a contact piece 17 having a tip of the fixing piece 16 bent outward, and a contact piece 17. And a male connecting portion 4 formed of a tongue piece 17a having a tip bent in a hazel shape.

A plurality of flowing water portions 9 are formed by drilling holes in the upper side wall 8 at a constant pitch so that rainwater or the like that has entered by any chance can be discharged to the outside. Of course, the pressing piece 13 is also cut away to remove the flowing water 9
May be formed. Further, the formation of the contact piece 17 is effective in improving the construction efficiency, the construction accuracy, the connection strength, and the like of the fixtures A.

[0009] The hard wall material B is a ceramic plate, a cement plate,
Extrusion of calcium carbonate plate, calcium silicate plate, wood chip cement plate, magnesium carbonate plate, etc., or those mixed with glass fiber, whisker, aramid fiber, steel fiber, carbon fiber, various mineral fibers, various aggregates, etc. Molding, press molding, injection molding, papermaking, etc., or various fibers woven into a cloth or three-dimensional shape, impregnated with cement, clay, etc. and molded into a panel shape are dried and steamed Cured, fired, etc., or made of metal panels, metal siding materials, wood boards, synthetic resin boards, etc.

More specifically, as an example of the hard wall material B, as shown in FIG.
8 at the upper and lower ends in the width direction.
And the locking groove 2 is formed at the notch corner of the male part 20.
1. The locking piece 22 is formed.

FIG. 2 (c) shows a fixture A and a hard wall material B.
It is sectional drawing which shows the mounting state of. Also, as shown in FIGS. 2B and 3C, the engaging piece 11
W <w, H>, where W is the length from the innermost to the upper end of the locking groove 21, w is the depth of the insertion groove 14, and h is the depth of the locking groove 21. h.

Next, the mounting structure of the hard wall material according to the present invention will be described in detail through working examples. Now, FIGS. 2 (a) to 2 (c)
1 and 3 using a fixture A and a hard wall material B as shown in FIG.
Assume that the construction is performed as shown in (a) to (d) and FIGS. 4 (a) to (d). Therefore, as shown in FIGS. 3A and 3B, a wooden substrate including a heat insulating material (glass wool or the like), a waterproof sheet (a windproof and moisture-permeable sheet), a steel frame substrate, an existing outer wall, and the like are placed on a wall substrate α. Then, the fixture A is fixed without any gap by the fixture β. The fixing piece 16 is fixed by a fixing tool β as necessary.

Next, as shown in FIG.
The female part 19 of the hard wall material B is inserted as shown by the arrow in the insertion groove 14 formed by the above construction, and then the hard wall material B is rotated as shown by the arrow in FIG. Then, FIG.
As shown in FIG. 4 (c), it is made to hang downward and constructed as shown in FIG. 4 (d). In this case, since the female part 19 can be inserted into the rotation groove 7 in the insertion groove 14, insertion-rotation is easy, and workability is remarkably improved.
The wall structure of the hard wall material B as shown in FIG. Needless to say, construction is performed by using drainage, a starter, eaves on the eaves, and corners, corners, etc. on corners. Note that a packing material such as EPDM is formed between the fittings A to enhance waterproofness.

In the mounting structure as described above, the female portion 19 and the locking groove 21 of the hard wall material B are fixed by the pressing piece 13 and the engaging piece 11 of the mounting tool A. And the hard wall material B during construction can be prevented from being damaged.

Further, the pressing piece 13 of the fixture A further presses the female part 19 of the lower hard wall material B by its own weight of the hard wall material B installed on the upper row, so that the hard wall material B is loose. There is no.

Furthermore, since the rotating groove 7 exists in the insertion groove 14 even after the installation, there is a space enough to remove the hard wall material B, and if the hard wall material B is damaged after the installation, But you can easily replace them one by one,
The hard wall material B may not be directly fixed to the wall foundation α with the fixing tool β, and can follow even if a deformation load is applied to the wall foundation α due to an earthquake or the like, and does not peel off. .
