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 casting concrete when constructing a foundation of a building structure such as a house, and more particularly to a foam insulation formwork and a method of constructing the same. is there.

[0002]

2. Description of the Related Art Conventionally, when constructing the foundation of a building structure such as a house, each of the steps of ground root cutting, split chestnut ground work, waste concrete (hereinafter referred to as waste concrete), and base concrete pouring is performed. After passing through, a formwork made of a plywood panel or a metal panel is assembled and arranged, and then a foundation is formed by placing concrete in the formwork. In recent years, in cold regions and the like, foam insulation models such as expanded polystyrene, which is also effective as a heat insulating material, have been used in place of the plywood panels and metal panels.

[0003] More recently, it has been proposed to form the foamed heat insulating form into a small hollow block, assemble the hollow block form up, down, left and right to form an integral form, and cast concrete into the form. Construction methods have also emerged that form the foundations.

[0004]

However, in the case of a mold using a conventional plywood panel, work such as cutting and nailing of plywood is troublesome, and in the case of a mold using a metal panel, the weight of the panel is large. However, there were problems such as heavy weight and poor workability. Also, in the case of the conventional foam insulation formwork, after curing the concrete, it is necessary to remove either the formwork in order to make the inside insulation or the outside insulation foundation, but the foam insulation material such as expanded polystyrene adheres to the concrete. Therefore, the removal of the mold was troublesome, and the removed foamed heat insulating material became garbage, which was not an environmentally favorable state.

Further, in the case of a hollow block-shaped formwork, a connecting member for connecting the formwork on both sides is integrally formed or mounted in the formwork, so that the rebar work is troublesome, and after the concrete is cured. However, since the mold cannot be removed, there is a problem that even the originally unnecessary form is used, and the product price becomes expensive.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, has no need to cut or nail a panel, is lightweight, and has an inner or outer heat insulating base by removing a mold on one side. It is an object of the present invention to provide a foamed heat-insulating formwork that can be easily constructed and that can reuse a removed formwork, and a method of constructing the same.

A foamed heat insulating form on which a good release agent / peeling plate is applied or adhered is thickened, a round separator (hereinafter, referred to as a round separator), a fixing bracket, and a bottom so that the application surface or the application surface is oriented in the same direction. After assembling with the mounting bracket, install it on the footing or discard container. In the corner portion, a corner accessory formed by bending the flat foamed heat insulating material in accordance with the corner is provided.

According to a second aspect of the present invention, a mold is formed on one surface (inner surface) of a flat foamed heat insulating material in which a step forming a footing is stepped in parallel at an angle of about 45 degrees. A foam insulation frame (for forming footing) coated or pasted with a good release agent / peeling plate is cut so that the application surface or the adhesion surface faces each other (the stepped portion forms footing). After assembling with the round separator, the fixing bracket, and the fixing bracket for the bottom part, install it on the waste container. In the corner portion, a corner role is formed by bending and molding a flat foamed heat insulating material having a step at about 45 degrees in parallel with the corner.

In the first and second aspects of the present invention, the release agent / release plate is usually applied or adhered to only one side. May be used.

Next, as a construction method of the foam insulation formwork in the first invention and the second invention, as described in claim 5 of the third invention, the same length as the thickness of the rising portion is used. About 25 mm thicker than the outer end of the entire foam insulation form.

[0020]

As described above, the following effects can be obtained by using the foamed heat insulating mold of the present invention. Since the foam is a heat-insulating form having a form-connecting portion having a standardized size, there is no need for cutting or nailing on site, and it is lightweight. A release agent / release plate with good releasability is applied or stuck on one or both sides of the foamed heat insulating material, and furthermore, the mounting structure of a round separator, a bottom fixing bracket and a thick end (C channel, pipe) is simple. Therefore, it is easy to remove the foam insulation frame after curing the concrete, and it is possible to easily construct the inner insulation or the outer insulation foundation. The removed foam insulation formwork is hardly damaged by concrete, and can be reused at the next foundation construction. When a release agent / peeling plate is applied or stuck on the entire surface, or when the applied surface or the stuck surface is constructed so as to be on the opposite side to the concrete surface, the terminus or rat may be used depending on the applied surface or the stuck surface. Damage can be prevented.
