Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a building formed by framing members which are assembled in a lattice shape and airtightly closes the opening, and an outer wall structure thereof.

[0002]

2. Description of the Related Art Conventionally, as an outer wall structure of this type of structure, for example, a structure described in Japanese Utility Model Laid-Open No. 7-6313 is known.

The outer wall structure of the building described in Japanese Utility Model Laid-Open No. 7-6313 has an outer heat insulation method with a small heat loss coefficient,
That is, in a factory, a frame member is assembled in a frame shape to a size that fits into a frame opening that is opened by a frame member that is framed to form a frame body, and stud members are attached in a lattice shape in the frame body. In addition, the base frame is formed by attaching bracing members in a diagonal shape on the diagonal of the frame to form a base urethane frame, and a rigid urethane foam plate slightly larger than the outer size of the base frame is set to a predetermined size from the outer peripheral edge of the frame. It is formed by protruding and fastening with nails.

In the field of the outer wall structure of this building, the base frame is fitted into the frame opening between the frame members that are framed, and the peripheral edge of the rigid foamed urethane plate on the side of the base frame is framed. Abut the member, fix the frame to the frame member and attach it, and airtightly attach the airtight tape across both sides to the edge of the hard urethane foam plate of another outer wall structure adjacent via the frame member, A room or other space is airtightly partitioned from the outside.

[0005]

However, in the structure of the conventional structure described in Japanese Utility Model Laid-Open No. 7-6313, both ends of the bracing member are processed along the outer peripheral edge of the corner of the frame. However, it is difficult to improve the workability by automation, and it is necessary to perform the processing manually, which lowers the productivity and increases the manufacturing cost.

Further, since the brace member disperses the stress applied to the base frame by the expansion and contraction of the brace member itself in the longitudinal direction,
When a large stress such as a large earthquake is applied, the stress is dispersed only by the bracing members, so that the base frame may not be able to disperse the stress, and durability against further large stress is desired.

On the other hand, the dimensions of the frame members such as columns may differ depending on the construction area, and if the outer wall structure having different thickness dimensions is formed in accordance with various floor plans of the construction owner, the items As a result, the productivity increases, the productivity decreases, inventory management and construction work become complicated, and the cost increases.

Further, stress may be exerted due to a difference in expansion and contraction between the frame members and the frame body or the base panel body mounted between the frame members, and there is a possibility that the decorative surface is deformed.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a building and its outer wall structure, which have improved manufacturability and workability, excellent stress dispersion, and improved durability. To do.

Further, the foam synthetic resin plate 11 is attached to the base panel body 10.
Since it is made larger, the foamed synthetic resin plate 11 is continuously located on the frame member 2 such as a pillar, a base, and a beam, the base panel body 10, and the outside 4b side of the basic concrete. Since concrete and ground have a great effect of storing heat and storing cold, energy saving can be further improved.
