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 panel, which is mainly applied to remodeling an outer wall of a building, particularly an outer wall of a low-rise detached house.

[0002]

2. Description of the Related Art Painting is widely used as a form of reforming the outer wall of a building for the purpose of improving appearance and decoration. However, although reforming by painting requires a low construction cost, peeling and stains are likely to occur early and there is a problem in that frequent repainting is required. In order to avoid such a problem, there is a reform form in which the outer surface of the existing outer wall is covered with an exterior panel having excellent durability. There, a base structure is assembled on the outer surface of the outer wall,
An exterior panel of a predetermined size is attached to the base structure to form a new outer wall. The base structure is formed by assembling channel materials and angle materials in a vertical and horizontal grid pattern, and supports the exterior panel in a state of being separated from the existing outer wall by 15 to 20 cm.

In the present invention, the exterior panel is hooked and fixed to the base structure one after another. Regarding this fixation structure, in Japanese Patent Publication No. 3-24942, the head of a screw screwed into the exterior panel is It is disclosed that the exterior panel is attached by engaging with a keyhole-shaped engaging hole provided in the base frame. Further, Japanese Utility Model Publication No. 58-7851 discloses that a screw shaft end of a screw is provided with an angular shaft portion for hooking a spanner in order to facilitate the screwing operation of the screw after being locked. There is.

[0004]

In the above-mentioned exterior panel mounting structure, a large amount of manpower and materials are required to construct the underlayer structure made of channel material, etc., and a series of operations from construction of the underlayer to mounting of the exterior panel. There is a disadvantage that the construction cost is high as a whole because it can be done only by a professional worker.

The outer wall surface after reforming is 1 from the existing outer wall.
Since it projects by 5 to 20 cm, reforming cannot be performed unless the outer wall is completely open. If the base structure is provided in close contact with the outer wall, the amount of protrusion of the outer wall surface after reforming can be reduced, but then it becomes difficult to fix the exterior panel to the base structure inside the exterior panel. This is because a bolt or a rivet is used to fix the exterior panel, but it is necessary to secure a space for performing the tightening operation between the exterior panel and the existing outer wall.

The object of the present invention is to improve the mounting structure of the exterior panel, thereby simplifying the underlying structure, and allowing the unskilled worker to mount the exterior panel accurately and easily. It is to provide a mounting structure for an exterior panel that can significantly reduce construction costs.
Another object of the present invention is to provide an exterior panel mounting structure capable of sufficiently reducing the protruding dimension of the outer wall surface after reforming and performing reforming without being affected by the state of the periphery of the building outer wall. is there.
