Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for an outer wall material in which the outer wall material is fixed in such a manner that the outer wall material slightly overlaps vertically in a siding condition.

[0002]

2. Description of the Related Art Conventionally, as a fixing structure of an outer wall material, an upper end of a base material side of the outer wall material is protruded upward in order to improve the flow of rainwater and to improve the appearance. The lower end of the outer wall material is projected downward, and the upper and lower outer wall materials are slightly overlapped with each other up and down with the lower end on the front side of the upper outer wall material facing forward, and fixed to the base material with fixing brackets. The fixing structure of the material is described in JP-A-7-300969 and the like.

In the fixing structure of the outer wall material disclosed in Japanese Patent Application Laid-Open No. 7-300969, a fitting groove is provided at a lower end portion of the outer wall material so that a lower end of the outer wall material is fitted and fixed to the fixing bracket. A protrusion and a fitting groove for fitting and fixing the upper end of the outer wall material are provided, and a fixing bracket is arranged and fixed to the overlapping portion of the upper and lower outer wall materials.

[0004] The procedure for constructing the fixing structure of the outer wall material is as follows. First, a fixing bracket is attached to a base material portion which is the lowermost end of the outer wall material, and a fitting groove of a lower end portion of the outer wall material is fitted to a fitting projection of the fixing bracket, and the upper end of the outer wall material is fixed next. The fitting is fitted into the fitting groove of the fitting, and the fixing fitting is fixed to the base material, and the upper end of the outer wall material is fixed.
The lower end of the next upper outer wall material is fitted to the fitting projection of the fixing bracket, the upper end of the outer wall material is fitted to the fitting groove of the next fixing bracket, and the fixing bracket is fixed to the base material. And
Fix the upper end of the outer wall material. By repeating this fixing operation of the outer wall material, the outer wall material is sequentially fixed in a siding state with the fixing metal fitting from the bottom upward.

[0005]

However, in the above-mentioned prior art, the upper and lower outer wall materials are slightly overlapped with each other vertically so that the lower end of the upper outer wall material on the front side is closer to the front side. Since the fixtures are sequentially fixed from below, the work of fixing the upper outer wall material cannot be performed until the lower outer wall material is fixed, resulting in poor construction efficiency. In addition, if many outer wall materials are fixed and the outer wall material other than the upper end is damaged after completion of the outer wall, the outer wall material can not be replaced unless the fixing bracket and the outer wall material from the top to the corresponding location are sequentially removed was there.

An object of the present invention is to solve the above-mentioned problems of the prior art, and to provide an outer wall material fixing structure which can fix an outer wall material from anywhere, has a high construction efficiency, and can easily repair and replace the outer wall material. is there.

[0007]
