[0002]

2. Description of the Related Art In recent years, in general wooden constructions, a heat insulating material may be provided on a concrete foundation in order to enhance the heat insulating effect indoors and to prevent distortion of the skeleton due to a difference in temperature.

As a basis of a wooden building, for example, FIG.
As shown in Fig.3, abandoned concrete 2 is placed on the rubble stone 1 which has been compacted by the rammer, and footing 3
It is known that the base 6 is fixed by the anchor bolts 5 inserted into the cloth foundation 4, and the cloth foundation 4 is erected on the footing 3.

In the case of arranging a heat insulating material on such a concrete foundation, a heat insulating panel is temporarily attached to one of the wooden concrete forms made of a control panel or the like, and one of the forms and the other concrete are used. A concrete pouring space was formed with the formwork, and concrete was poured into the pouring space. Then, after hardening of the concrete, a pair of concrete formwork consisting of a control panel was removed, whereby the heat insulating panel was attached to the concrete.

However, a series of operations for constructing such a concrete foundation requires a skilled worker such as a formworker, a large amount of wood and a great deal of labor.

[0006] Therefore, today, while reducing the use of wood, a basic formwork is made of a heat insulating material made of resin foam so that the foundation of the heat insulating structure can be constructed without a skilled worker. The heat insulation foundation panel to be constructed and its heat insulation foundation construction method are being adopted.

When the concrete foaming space is formed by the resin foam itself, as shown in FIG. 7, for example, a concrete pouring space 8 whose both surfaces are sealed by two resin foam panels 7, 7 is provided. After defining, then inserting a separator or the like (not shown) between the panels 7 and 7 to set the concrete placement width, and further arranging vertical and horizontal reinforcing bars 9, and then placing concrete through the upper opening 10. It was designed to build a concrete foundation with footing.

[0008]

However, in the case of constructing a concrete foundation with footing using the above-mentioned conventional resin foam panels 7, 7, as shown in FIG. When C is poured, the concrete C cannot be poured to the originally planned part, and as a result, the concrete C that has flowed in does not have a predetermined shape and is solidified in a thin state. there were. As a result, conventionally, in order to prevent the strength of the concrete foundation from being insufficient, the width between the resin foam panels 7, 7 is made thicker than a preset value, or the water content is increased to increase the inflow rate of concrete. It was necessary to consider such as

In view of the above situation, the present invention makes it possible to easily and quickly construct a cloth foundation with footing for a building by providing the mold itself with a high heat insulating property, and it is difficult to pour concrete. It is an object of the present invention to provide a heat insulating foundation block that also serves as a formwork, which can give concrete strength by sufficiently pouring concrete into the corners.

A further object of the present invention is to provide a heat insulating foundation block which also serves as a formwork, and whose wall surface can be extended integrally with the upper portion of the cloth foundation.

[0011]

According to the present invention, a concrete spout is provided in addition to the upper opening in order to allow the concrete to sufficiently reach the corner where the concrete does not flow easily. This allows the concrete to be poured into the corners.

The cloth base form part and the footing form part may be composed of two detachable form parts, and one of the cloth base form parts may also serve as a wall surface. I am able to do it.
