Description

  The present invention relates to an exterior material attachment structure in which an exterior material is attached to the surface of an outer wall main body.

In recent years, the construction of houses has been industrialized. For example, there is a panel construction method in which components such as walls, floors, and roofs are made into panels in the factory in advance and these panels are assembled at the construction site to construct the house. Adopted in some areas. As a wall panel used in such a panel construction method, the frame is constructed by assembling the eaves into a rectangular frame, and assembling the reinforcing core vertically and horizontally inside the rectangular frame, and on both the front and back sides of this frame The one to which a face material such as plywood is attached is common.
And in order to form an outer wall using such a wall panel, waterproofing moisture-permeable sheets, such as a Tyvek, are stuck on the outer surface side of a wall panel. Furthermore, after attaching the trunk edge to the waterproof and moisture permeable sheet by nailing, an exterior material made of lightweight cellular concrete is attached and fixed on the trunk edge by nailing. Thus, a space is formed between the outer surface of the wall panel and the exterior material by attaching the exterior material to the outer surface of the wall panel via the trunk edge. This ensures air permeability.
Here, as a method of attaching the trunk edge and the exterior material, the lateral trunk edges that are long in the lateral direction are attached so as to have a predetermined interval in the longitudinal direction, and the exterior material is placed in the longitudinal direction on the lateral trunk edges. It is common to install so that is in the vertical direction. In addition, there is also known a technique in which a longitudinal body edge that is long in the vertical direction is attached so as to have a predetermined interval in the transverse direction, and an exterior material is attached on the longitudinal body edge so that the longitudinal direction is in the transverse direction. (For example, refer to Patent Document 1).
