DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure for an exterior decorative panel for a building, such as a gaze, a blindfold, or a gable used for an outer wall of a general residential building, and more particularly, it is formed of ceramic materials. The present invention relates to a mounting structure for a building exterior decorative panel using a decorative panel and a mounting bracket.

[0002]

2. Description of the Related Art Conventionally, a conventional mounting structure of an exterior decorative panel formed of a ceramic material as described above was originally directly screwed to a building frame. In order to prevent the head of the screw from appearing on the appearance and to prevent the panel from cracking due to the tightening of the screw, the mounting bracket 31 is screwed to the building frame 47 as shown in FIG. A structure in which a screw is not screwed into the decorative panel 42 is adopted by fitting and fixing the decorative panel 42 to the metal fitting 31.

[0005] Referring to the conventional example of FIG. 5, a mounting bracket 31 includes a plate portion 32 which is fastened and fixed with screws 48 along an outer wall surface of a frame 47, and extends substantially perpendicularly from the plate portion 32, and further substantially. The hook 33 is bent at a right angle and adapted to receive the fitting jaw 43 of the decorative panel 42. The fitting jaw 43 of the decorative panel 42 extends from the upper end of the decorative panel to the rear side and is bent downward at a substantially right angle. The width is set to be substantially equal to the inner width dimension of the portion 33. Accordingly, the entire decorative panel 42 is supported in a state where the fitting jaw 43 is hooked on the hook-like portion 33 of the mounting bracket 31 in a fitted state, and hangs downward. Further, the fitting relationship between the jaw 43 and the hook-shaped portion 33 is dimensioned so as to be tightly fitted in order to prevent rattling after the decorative panel 42 is attached. It is necessary to push with strong force.

By the way, the decorative panel 42 is attached to the building frame 47 by successively adding a plurality of panels in the longitudinal direction, and if the continuity of the shape is interrupted at the joint, it is very undesirable from the viewpoint of aesthetics. The surface of the building skeleton 47, which is the mounting surface of the decorative panel 42, is often a surface that is considerably rough compared to the dimensional accuracy of the decorative panel 42 and the mounting bracket 31, and such a surface is often provided with the decorative panel 42.
Is attached, there is often a step in the thickness direction of the panel at the seam, and it is difficult to absorb the step with the conventional mounting structure having the above-described configuration. Further, ceramic-type decorative panels are long and difficult to handle, and when a step occurs, it is very difficult to correct the step. In a conventional decorative panel mounting configuration using a mounting bracket, improvements are required in these respects.

The present invention has been made in view of the above-mentioned conventional technical problems, and has been devised to effectively solve the problems.
Therefore, an object of the present invention is to provide a mounting structure of a building exterior decorative panel that can easily absorb a step generated at a joint portion of a decorative panel even if the surface of a building frame is slightly rough.

[0006]

SUMMARY OF THE INVENTION A mounting structure for an exterior decorative panel for a building according to the present invention has the following structure to solve the problems of the prior art as described above and to achieve the object. . That is, in a structure in which a building exterior decorative panel made of a ceramic material is mounted on an outer wall surface using a mounting bracket, the metal fitting receives a fixing portion fixed to a building frame and an end of the decorative panel from above. Having a concave portion, the decorative panel has an engaging convex portion pushed into the receiving concave portion of the mounting bracket, and furthermore, in order to adjust a mounting step in a thickness direction of the decorative panel,
At least one side surface of the engaging projection projects in the thickness direction of the decorative panel, and the inner surface of the receiving concave when the engaging convex is pushed into the receiving concave to attach the decorative panel to a mounting bracket. At least one step-adjusting small protrusion that can be worn away by being rubbed against is formed.

[0007]

In the structure for mounting an exterior decorative panel for a building according to the present invention, the decorative panel is mounted on the building frame by pushing the engaging projection of the decorative panel into the receiving recess of the mounting bracket. Decorative panel is cement,
Since it is made of ceramic materials mainly composed of gypsum and mineral fibers, its brittleness is relatively strong, and small protruding parts are relatively easily crushed when rubbed against hard materials such as metal fittings. And wear and tear. The small projections formed on one side surface of the engaging projections, when the engaging projections are pushed into the recesses of the mounting bracket, are rubbed against the inner wall surfaces of the recesses and worn away, whereby the panel relative to the mounting bracket is worn. Can be changed and adjusted in accordance with the amount of wear. If the shape of the projection is made smaller toward the tip, the amount of wear can be adjusted by adjusting the intensity of the rubbing pressure, and the entire small projection can be peeled off or chipped off from its base Never. By actively abrading the small projections, even if there are some irregularities on the surface of the building frame, the unevenness in the thickness direction of the panel due to the irregularities can be easily absorbed by the abrasion of the small projections. The decorative panels can be beautifully arranged and installed. In addition, if the number of small projections is plural, the posture of the panel after mounting is stabilized.
