Description

[0001]
BACKGROUND OF THE INVENTION
The present invention is an outer heat insulating wall structure in a general outer heat insulating method in an apartment or the like.
[0002]
[Prior art]
As the thermal insulation construction method for the building outer wall, the inner thermal insulation construction method in which a thermal insulation layer is attached to the inside of the building outer wall has been widely used.However, the structural stress of the building outer wall is exposed to the outside air, which causes thermal stress. There are many problems such as cracking due to frost damage, damage, and deterioration of heat insulation effect due to heat cooling.
[0003]
Therefore, an outer cutting method has been developed to attach the heat insulating material layer to the outside of the outer wall, and when the heat insulating material layer is provided on the outside air side, the surface is exposed to rainwater, solar radiation, wind and snow, etc., which is impossible in terms of weather resistance performance. Therefore, install an exterior finish panel on the outside air side of the insulation layer.
[0004]
The following patent document is one of them, and it is possible to easily attach the exterior panel without directly attaching the exterior panel mounting bracket to the concrete structure housing, and the outside air between the exterior panel and the heat insulating material layer. A circulation air layer can be formed.
[0005]
[Patent Document 1]
Japanese Patent Laid-Open No. 9-228503 (Dry-type external heat insulation construction method for building outer wall)
[0006]
In Patent Document 1, as shown in FIG. 5, a heat insulating material layer 3 is formed in an interior partitioned by an outer wall surface of a concrete frame 6 of a building and a trunk edge 4 attached to the outer wall surface in a rectangular frame shape. A mounting bracket 2 having latching projections at a predetermined interval is fixed to the body edge 4, and an exterior finishing panel 1 is arranged on the mounting bracket 2, so that the exterior finishing panel 1 and the heat insulating material layer are arranged. 3, an outside air circulation air layer is formed.
[0007]
In addition, although the cement-type inorganic board is used a lot for the exterior finishing panel 1, it is set as the tiled building outer wall by arranging a tile in an underground panel.
[0008]
When the exterior finish panels 1 are arranged, as shown in FIG. 6, the exterior finish panels 1 are arranged as so-called “lines” such that the lower end of the upper panel overlaps the upper end of the lower panel. It is done. In the case of FIG. 6, the trunk edge 4 is fixed with a nail 5, but it may be an anchor bolt or the like.
[0009]
[Problems to be solved by the invention]
When repairing or replacing the exterior finishing panel 1 or the heat insulating material, a scaffold is required, and when installing a framework scaffold, the building is taken from the concrete frame of the building. However, in the conventional internal cutting method, since the finished tile is stretched directly on the outer wall concrete which is a concrete frame, the connecting anchor bolt can be easily attached to the concrete frame. In the outer heat insulating method as shown, the presence of the heat insulating material layer 3 and the outside air circulating air layer makes it difficult to drive the anchor bolt.
[0010]
Also, as shown in Fig. 6, the exterior finish panel has a "Sane" structure as seen in siding, etc., and it is raised from the bottom to the top. This also makes it difficult to install the anchor bolt.
[0011]
In view of the present situation, the present invention eliminates the disadvantages of the conventional example described above, and in the outer heat insulating wall structure in which the heat insulating material layer is provided on the outer wall surface of the concrete frame of the building and the exterior finish panel is further installed thereon. To provide an external heat insulating wall structure that can be easily attached to an anchor when installing a scaffold when repairing a scale or partially replacing an exterior finish panel, and that allows the partial replacement of the panel itself to be made inexpensively. It is aimed at.
