Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a concrete formwork and a wall structure in which the concrete formwork and the concrete are integrated.

[0002]

2. Description of the Related Art In recent years, for the purpose of increasing the standards of houses by increasing the insulation and airtightness of the houses, and for the purpose of facilitating construction and greatly reducing the cost of house construction, two-by-four, etc. Concrete formwork combined with synthetic resin molded body to form the cloth foundation of a wooden house or the wall of a reinforced concrete building, the reinforcing bars arranged in the formwork, and the inside of the formwork Attention has been paid to building walls made of hardened concrete which has been widely used.

[0003] The combination type concrete formwork of such a synthetic resin molded body is roughly classified into, for example, Japanese Patent Application Laid-Open No. 6-12 / 1994.
As described in No. 9099, a side panel member made of a synthetic resin such as expanded polystyrene having a concave-convex structure as a joint end on an edge and having a T-shaped cross-sectional groove extending from the joint end toward the center. A spacer member inserted into the side panel in order to fix a gap between the side panel members facing each other. (Since such a spacer member is functionally subjected to a tensile force, a tension member is used. However, it is also referred to as a spacer member in this specification) to form a formwork, or as described in, for example, JP-A-6-346536, between facing panel members. Some bridge members are formed by stacking bridge members that are cast into a panel member to form an integral building component.

[0004]

However, since a reinforcing bar is embedded in the concrete of a building, Japanese Patent Laid-Open No. 6-12 / 1994.

An operation of arranging a reinforcing bar at a predetermined position of the surging member or the bridging member is also required.

[0005] Here, after a panel member made of synthetic resin is joined or picked up to form a concrete form, long rebars are not inserted unless the form is for a straight wall having open side surfaces. Since it is difficult to insert the reinforcing member, once the panel member made of synthetic resin is formed and the spacer member or the bridging member is mounted at a predetermined position, it is necessary to perform an operation of inserting a reinforcing bar next.

Further, when the reinforcing bar must be inserted in a plurality of levels with respect to one panel member, the mounting of the reinforcing bar and the insertion of the spacer member must be performed simultaneously. Also, it is impossible to arrange reinforcing bars that are assembled in a grid or the like by welding, wire fastening, or the like over a plurality of panel members.

[0007] As described above, the stacking of the synthetic resin panel members and the mounting of the reinforcing bars must be performed alternately, and even if these are performed alternately, the walls of the panel members facing each other for forming the formwork may not be formed. If both are at the same height, the rebar arrangement work is troublesome and the inability to arrange rebars pre-assembled reinforces such concrete, which is one of the objectives of reducing construction costs. This is a major drawback for the construction of the building.
