Abstract

PROBLEM TO BE SOLVED: To provide the support tool for a foundation concrete form firm and small in a housing space without requiring assembling working at a construction jobsite by making the width of the substantially half of a base board smaller than the inner width of a support leg. SOLUTION: The base board 1 of the lower part receiving the weight of concrete and the support leg 2 comprising a reinforcing bar unit receiving part 2a and a rise part form receiving part 2b are welded to constitute the support tool of the foundation concrete form. In the constitution, the width of the substantially half of the base board is smaller than the inner width of the support leg 2. When storing, transporting or the like is performed, the substantially half of the base board 1 can be inserted in the support leg 2. Thereby the housing space is small, the assembling working is not required at the construction jobsite, and the support tool of the firm and inexpensive foundation concrete form can be obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for a foundation concrete formwork for molding foundation concrete in a building such as a house.

[0002]

2. Description of the Related Art In recent years, when molding base concrete for a house or the like, a form support as shown in FIGS. 7 and 8 is used to integrally form a base portion and a rising portion of the base concrete. It has come to be. One example of FIG.
The support legs 9 are welded to the substrate 8. This type of product does not require assembling the board and the supporting legs at the construction site, but since the board 8 is rectangular, it cannot be stacked as shown in FIG. 6, and the storage space is very large. Is needed. Therefore, there is a disadvantage that the cost for storage and transportation is high.

[0003] The two examples shown in FIG.
0a is provided, and the support leg 11 is fitted and used here. However, in this type, although the storage space can be made small, there is a drawback that assembling work is required at a construction site and the work cost is increased. In addition, since the form support itself is a disposable product, the fitting portion 10a cannot be made so strong from the viewpoint of cost, and there is a disadvantage that the form for the rising portion is loose.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned problems of the conventional form support, has a small storage space, and does not require an assembling operation at a construction site.
Another object of the present invention is to provide an inexpensive rigid formwork support for a foundation concrete formwork.

[0005]

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention supports a width of a substantially half portion of a substrate of a mold support so that approximately a half of the substrate can be fitted into a support leg. Should be smaller than the inner width of the leg.

[0006]

Hereinafter, the present invention will be described in detail based on illustrated embodiments. FIG. 1 is a three-dimensional view of an example of a formwork support for foundation concrete to which the present invention is applied. FIG. 2 is a top view. In this form support, a support leg 2 is welded to a substrate 1. The supporting leg 2 is provided with a form receiving portion 2b for a reinforcing bar unit receiving portion 2a and a rising portion. FIG. 3 shows the situation at the time of use. Here, as shown in FIG. 2, the projection 1a is provided on the substrate 1 of the form support for foundation concrete according to the present invention.
Is provided, and the width N of the convex portion is smaller than the inner width W of the support leg. Therefore, as shown in FIG.
The storage space can be significantly reduced by fitting the convex portion 1a of the support member 2 inside the support leg 2. Further, since the substrate 1 and the support leg 2 are firmly welded, the rising portion formwork does not fluctuate. In addition, a reinforcing rib is formed on the outer periphery of the example substrate 1 by press working in order to increase rigidity.

Further, in this example, the protrusion 1
A concave portion 1b is provided on the side opposite to the side a. As a result, as shown by a two-dot broken line in FIG.
, The feed pitch L of the coil material at the time of material removal of the substrate 1 is approximately half the width 2L of the conventional substrate 8 shown in FIG. This means that the material cost of the substrate 1 is substantially half that of the conventional product, and that the product can be manufactured at low cost.

FIG. 4 shows two examples of a form support to which the present invention is applied. In two examples, an example is shown in which the support leg 6 is made stronger than one example. The support leg 6 is added to the support leg 6 and the substrate 5 and welded.

[0009]

According to the present invention, the shape of the substrate of the form support is formed so that approximately half of the substrate can be fitted into the support legs, so that the storage space is small and the assembling work at the construction site is not required. In addition, it was possible to provide an inexpensive and firm support for a foundation concrete formwork.
