Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for easily forming a mold by arranging a frame plate when constructing a basic concrete for a house or the like.

[0002]

2. Description of the Related Art Basic concrete has an approximately inverted T-shaped cross section, and this basic concrete is constructed by pouring concrete into a predetermined form. In this case, the formwork is made by vertically stacking veneer plates at regular intervals to form a base of basic concrete, and a rising formwork also having a narrow interval is installed on the base to pour concrete.
Therefore, it is necessary to separately form the base and the stand-up, which is not only a troublesome assembling work of the above-mentioned formwork but also the production of the formwork and the concrete is more difficult than the case where the foundation concrete is created at once. The number of man-hours required for the pouring work is doubled.

In recent years, the entire floor under the floor has been made a concrete surface to prevent the rise of water from the ground (moisture-proof) and to prevent the occurrence of termites by a moisture-proof treatment. Therefore,
In this case, the concrete surface is further formed on the ground after forming the basic concrete, and the concrete pouring work is performed three times.

[0004]

As described above, the conventional formwork of basic concrete has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a basic concrete formwork structure in which the assembling of the formwork is easy and the number of times of concrete pouring work is only required once.

[0005]

According to the present invention, the cross-sectional shape of the basic concrete is not the inverted T-shaped but the L-shaped cross-sectional shape, and the formwork is constructed so that the basic concrete having the L-shaped cross section can be formed. . Therefore, a support pillar is vertically erected at one end of the base, and a receiver is attached to the support pillar so as to be vertically movable, and the receiver can be fixed at a predetermined height. A frame plate is placed on and supported by this receiver.

An L-shaped mounting member is fixed to the base, and the L-shaped mounting member stands up from the base and bends at a predetermined height to form a horizontal portion. Is provided with a collar and a screw. Therefore, another frame plate facing the frame plate is attached to this horizontal portion. In order to support the horizontal portion of the mounting member, a support standing upright from the base is welded midway. Then, the foundation building streak frame is mounted on and supported by the mounting member.

As described above, the two frame plates which are parallel to each other are arranged upright vertically, but the frame plates located inside are supported by the receivers, and thus are largely separated from the base to leave a space. The concrete will be poured between the two frame plates, but the concrete will flow out from the space left under one frame plate to form a concrete layer on the bottom surface of the floor. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
