Description

[Detailed Description of the Invention] The present invention relates to the structure of an exterior part of a building wall. In the case of buildings with concrete structures, the external walls are subject to temperature changes directly, and there are problems such as cracks and structural deterioration due to exposure to sunlight, wind, snow, and rain. In order to prevent these, protective measures such as waterproofing, painting, or installing exterior panels are taken, but there are concerns regarding their effectiveness, durability, superiority in management, and appearance. From the point of view of aesthetic effects, etc., it is more preferable to attach an exterior plate.

Conventionally, the mounting structure for such an exterior plate is
For example, as shown in FIG.
The upper end 22a of the second exterior plate 22a is fixed with a screw 23, and the other exterior plate 22' is fitted with its lower end 22'c into a fitting groove 22b formed by bending the upper end.
Furthermore, a mounting structure has been adopted in which the upper ends of the exterior plates 22' are similarly fixed with screws to form a sequential connection structure.

However, according to such a conventional exterior structure, the space between the frame 21 and the exterior plates 22, 22' becomes a sealed structure, which prevents condensation on the wall surface of the frame 21, prevents moisture from dissipating, and prevents cold temperatures. There is a disadvantage that it has a negative effect on the frame 21 due to freezing in the ground, and also has the disadvantage that the exterior plates 22, 2 are attached to the frame 21.
2' is directly attached, so the frame 21
There is a risk of structural damage due to unreasonable expansion/contraction/behavior of the exterior plate 22,
22' had to be directly screwed, which had the disadvantage of poor construction efficiency.

In view of the above-mentioned drawbacks, the present invention has an insulating structure in which the frame and exterior plates are attached via a holder, and the interconnection of the exterior plates is an open structure to provide ventilation in the gap between the frame and the exterior plates. The purpose is to provide an exterior structure that is easy to install, does not cause condensation, does not cause structural damage, and is fixed at a predetermined position on the wall surface of the building frame and can be easily installed from the wall surface.
