Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a formwork used for constructing a foundation of a building structure such as a house, and more particularly, to a foam capable of constructing a cloth foundation or a solid foundation in one concrete casting. The present invention relates to a synthetic resin form and a foundation construction method using the form.

[0002]

2. Description of the Related Art Conventionally, when building the foundation of a building structure such as a house, after going through each process of ground root cutting, splittering, waste disposal, and base concrete placing, a plywood panel or a metal panel is used. After assembling the formwork that has become
The foundation was formed by casting concrete in the formwork. In recent years, in cold regions and the like, instead of the plywood panel and the metal panel, a foamed synthetic resin form such as foamed polystyrene which is also effective as a heat insulating material has been used.

The foamed synthetic resin form has a thickness of 50 m.
For example, a flat plate having a length of about m, a hollow block-shaped member which is assembled and used vertically and horizontally, and has a skirt portion for forming heat insulation of the skirt.

[0004]

However, when the above-mentioned flat or hollow block-shaped foamed synthetic resin form is used, two steps are required, namely, a base concrete casting and a rising part casting. There is a problem that the setting is performed twice and the construction period is required. Also,
Due to the deviation of the process, there was also a problem that the joint strength at the boundary surface between the previously cast base concrete and the later set up portion was weakened.

In order to solve the problem, the bottom of the foamed synthetic resin form at the rising portion is supported and floated by a metal base spacer, and after assembling the foamed synthetic resin form for placing base concrete, Construction methods have been developed in which a foundation is constructed by placing concrete once in a foamed synthetic resin form in a rising portion and in a foamed synthetic resin form for placing base concrete. However, the metal base spacer used in the construction method is composed of complicated parts having an adjustment mechanism, and is extremely expensive as compared with other members for constructing the foundation. There was a problem of inviting.

Further, when a foamed synthetic resin form having a skirt portion for forming heat insulation of the skirt is used, the base concrete and the rising portion are integrally formed, thereby shortening the construction period and improving strength. The foamed synthetic resin form itself becomes bulky, which causes a problem of increasing storage costs and transportation costs.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a cloth foundation or a solid foundation can be formed by a single concrete casting without using an expensive metal base spacer or the like. An object of the present invention is to provide a foamed synthetic resin form that can be easily constructed and does not bulk up even when constructing a skirt heat insulating foundation, and a foundation construction method using the form.
