DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for fixing a hard wall material without directly driving it with a fixing tool such as a nail.

[0002]

2. Description of the Related Art Generally, many hard wall materials, especially ceramic hard wall materials mainly composed of cement, having male and female portions having a definite structure formed on both side edges in the width direction are commercially available. When these hard wall materials are fixed to the wall foundation, a mounting hole is drilled on site by a drill, a nail is driven through the mounting hole, or a mounting tool such as a Z clip is mounted in the mounting hole. Processing of the hard wall material main body was necessary, such as fixing and fixing to the wall base.

[0003]

However, when performing processing such as drilling a hard wall material, it takes time and effort, and when the hard wall material is damaged by a drill, or when a nail or the like is driven, it is difficult to perform such processing. It was often destroyed by a hammer or the like. In addition, the skill is required for the worker, and it is very difficult to replace the hard wall material in the event that the hard wall material is broken after the construction.

[0004]

According to the present invention, in order to eliminate such drawbacks, a hard wall material is formed in a solid shape from a male part and a female part, and an upper end fitting is previously provided on the wall base. When fixing the hard wall material, attach the lower end fitting corresponding to the entire width of the hard wall material, insert the male part of the upper end of the hard wall material into the fitting groove of the upper end fitting, and engage the lower end fitting. The structure is such that the engaging groove of the female part of the hard wall material is dropped into the mating piece and the hard wall material is attached.There is no failure to break the hard wall material with a drill, hammer, etc. Efficient construction, improved fire protection and waterproofing, and replacement of hard wall materials after construction is easy, and a hard wall material mounting structure that can cope with errors in the width dimensions of hard wall materials It is a suggestion.

Extrusion molding, press molding, injection molding, papermaking method or the like mixed with fibers, various aggregates, etc., or various fibers are woven in a cross shape, three-dimensional shape,
It is formed of a panel formed by impregnating it with cement, clay or the like, steam cured or fired, or a panel formed by sandwiching a synthetic resin foam with a metal plate.

More specifically, as shown in FIG. 4, the hard wall material A has a long plate shape, and has a decorative surface 1 and an insertion edge 2 having one of the side walls at both ends in the width direction of the decorative surface 1 projecting outward. A male part 3 having the same, an engaging groove 4 formed in a substantially U-shape toward the inside and a covering piece 5 formed by projecting the decorative surface 1 side of the engaging groove 4 outward. The female real part 6 is formed, and the male real part 3 and the female real part 6 are formed in a definite manner.
Further, in FIG. 4, a plurality of linear hollow holes 7 are formed in the hard wall material A in order to reduce raw materials and weight.

The upper end fitting B and the lower end fitting C are mainly made of a color steel plate, an aluminum / zinc alloy plated steel plate, an aluminum plate,
Titanium plate, stainless steel plate, copper plate, fluororesin coated steel plate,
It is formed by roll forming or press forming a thin metal plate such as a clad steel plate, a laminated steel plate, or a vibration damping steel plate, or by extruding an aluminum alloy or the like.

As shown in FIG. 5, the upper end fitting B has a substantially vertical fixing piece 8, a rising piece 9 projecting substantially perpendicularly from the fixing piece 8, and a tip of the rising piece 9 protruding downward. Supporting piece 10 and supporting groove 1 formed in upper fixing piece 8
1, a support portion 12 that abuts against the back surface of the hard wall material A, a fitting groove 1 including a fixing piece 8, a rising piece 9, and a supporting piece 10.
3 is formed in an elongated shape.

More specifically, the upper end fixture B has a plurality of upper fixing pieces 8a and lower fixing pieces 8b horizontally fixed at a fixed pitch P on a wall base α via a fixing means β. The supporting edge 10 is used to fix the insertion edge 2 to be used.

Further, the support groove 11 is formed wider than the fixing protrusion 16 of the lower end mounting member C described later, and the fixing protrusion 16 is fixed in the supporting groove 11 so that the lower end mounting member C is mounted. It is useful for determining the position and for determining the range of the mounting position.

The groove 13a formed in the fitting groove 13
When the hard wall material A is removed, the male part 3 forms a space in which the male part 3 can rotate in the fitting groove 13.
Due to the formation of the groove portion 13a, it is possible to smoothly mount the hard wall material A without forming the opening of the fitting groove 13 large.
It can be removed.

As shown in FIG. 6, the lower end mounting member C has a vertically flat stabilizer 14, an engagement piece 15 having a lower end bent in a U-shape, and a tip of the stabilizer 14 having a substantially L shape. It is composed of a fixed protruding piece 16 bent in a character shape, and is a short one in the figure or a long one not shown.

More specifically, the lower end fitting C is provided with the fixing projection 1 in the support groove 11 of the fixing piece 8 above the upper end fitting B.
6 for fixing the fixing protrusion 16 to the wall foundation α by the fixing tool β. The engaging groove 4 serving as the lower end of the hard wall material A is engaged and fixed by the engaging piece 15. belongs to.

As shown in FIGS. 1 to 3, the mounting position of the lower end fitting C is determined by moving the fixed projection 16 of the lower end fitting C in the support groove 11 of the upper end fitting B. The mounting position is set to match the entire width W of the material A. Even if the entire width W of the hard wall material A changes due to a manufacturing error,

[0021]

As described above, according to the hard wall material mounting structure of the present invention, the hard wall material is fixed to the wall base via the upper end mounting member and the lower end mounting member. No processing such as installation is required, breakage and damage can be prevented, and construction is easy. Since the upper and lower end fittings do not appear at all in appearance, there is no lack of design. Since the hard wall material is engaged by the upper and lower end fittings and fixed by pressing, it can follow the deformation of the wall foundation due to an earthquake or the like, and can prevent breakage and peeling. Since the arrangement position of the hard wall material is determined by the lower end fixture, a dimensional error in the hard wall material (about 2 to 5 mm)
Can be securely attached even if a problem occurs. After arranging the lower end fitting on the entire surface of the wall foundation, it is possible to install hard wall materials while adjusting with the lower end fitting, and to achieve higher efficiency of construction, and from outside after construction, If the hard wall material is damaged by the impact, it can be easily replaced. Since the supportable range of the lower end fitting is limited by the support concave groove of the upper end fitting, the hard wall material is not attached to a position where the hard wall material cannot be detached. Since the groove is formed in the fitting groove of the upper end fitting, attachment and detachment are easy and reliable. There are features and effects such as.
