Description

[Detailed Description of the Invention] (Industrial Field of Application) This invention relates to a support tool used to support a concrete formwork when pouring concrete for a concrete foundation.

(Prior Art) The applicant of this invention, in a previous utility model registration application (Utility Model Application No. 36021/1983), proposed that a support member formed into a substantially gate shape made of metal wire be erected on a substrate. The support is configured to support a pair of fabric foundation concrete formwork on the support member, and can be easily packed, transported, stored, etc. without adding bulk when the substrate and support member are disassembled. I suggested the ingredients.

(Problem to be solved by the invention) However, in the configuration of this prior application, the support member is simply gate-shaped, which makes it easily deformed, and the formwork for cloth foundation concrete is mounted on the support member. There was a problem in that when the mold was placed, the support member wobbled under the weight of the mold, making it impossible to support the mold in a stable state.

Structure of the device (Means for solving the problem) This device was developed by focusing on the above-mentioned problem, and is based on a support member formed into a gate shape made of metal wire and placed on a foundation made of paving stones, etc. In the support device, which is arranged upright on a substrate disposed on a substrate and supports a pair of cloth foundation concrete formwork on the support member, the substrate has a fitting portion having a substantially inverted L-shaped cross section. At the same time, a support piece for supporting the formwork for cloth foundation concrete is attached to the support member, and an engagement piece that can be elastically engaged with the fitting portion is attached to the lower end of the supporting member, and It consists of a pair of leg pieces attached to a support piece so as to be located directly below the formwork, and a crosspiece attached to the leg piece and the support piece, and the support piece, the leg piece, and the crosspiece A recessed portion for supporting the reinforcing bars for the cloth foundation is formed at the center of the upper part of the support member, and a pair of frame-shaped portions for preventing deformation are formed on both sides of this recessed portion.

(Function) Therefore, in the supporting device of this invention, the frame-like portion reliably prevents the supporting member from wobbling, and the engaging piece does not slip out of the fitting portion, so it is easy to use the formwork for cloth foundation concrete. It can be supported in a stable state.

(Example) Hereinafter, an example of a supporting device for a formwork for cloth foundation concrete embodying this invention will be described in detail with reference to FIGS. 1 to 4.

Now, in this embodiment, the substrate 1 constituting the support is formed into a rectangular flat plate shape from a thin metal plate such as iron. A pair of latching pieces 2 and 3 are bent at both ends of the upper surface of the substrate 1, and a latching portion 4 is formed between the latching pieces 2 and 3. A pair of right and left protrusions 5 having a substantially inverted L-shaped cross section are formed by punching in the center of the upper surface of the substrate 1, and these protrusions 5 form a pair of left and right fitting portions 6 that open toward each other inwardly. ing.

Similarly, the support member 7 constituting the support is constructed by welding and fixing a metal wire such as iron. That is, engagement pieces 9 extending in the front-rear direction and capable of being elastically fitted into and engaged with the fitting portion 6 on the substrate 1 are welded and fixed to the lower ends of a pair of left and right leg pieces 8 extending substantially parallel to each other in the up-down direction. A support piece 10 having a substantially inverted L shape from the front is welded and fixed to the upper end of each leg piece 8, and by this welding, each leg piece 8 can be
The position is set directly below the formwork 16 for cloth foundation concrete supported by the support member 7. Between the center portions of both leg pieces 8 is a horizontal support 11 for preventing wobbling.
are constructed and fixed by welding, and the inner lower ends of the support pieces 10 are respectively welded and fixed to the intermediate portions thereof. In this embodiment, a support recess 12 is formed in the center of the upper part of the support member 7 by the support pieces 10 and the horizontal beams 11, and the support pieces 10, the crosspieces 11, and the leg pieces 8 provide support. A pair of frame-shaped parts 13 for preventing deformation are formed on both sides of the recessed part 12.

In this way, since the substrate 1 and the support member 7 constituting the support are separate, it is difficult to pack, transport, store, etc. with a large number of the substrates 1 and support members 7 stacked one on top of the other. It can be easily done without any trouble. In addition, when using this support, at a concrete pouring site, while bending the lower ends of both leg pieces 8 of support member 7 inward, both engaging pieces 9 are attached to fitting portions 6 on substrate 1. By elastically fitting and engaging with each other, the supporting member 7 can be easily assembled onto the substrate 1, and the engaging piece 9 will not slip out from the fitting portion 6.

As shown in FIG. 2, if the base plate 1 of the support is placed on the paving stones 15 in the groove 14 provided in the concrete pouring part or on the foundation made of waste concrete, both support pieces of the support member 7 can be placed. The formwork 16 can be supported for molding the cloth foundation part (rising part) of the foundation concrete on the foundation 10, and the foundation can be supported between both the hooks 4 of the substrate 1 and the support pieces 10 of the support member 7. A pair of formworks 17 having a substantially inverted L-shaped cross section for forming a concrete base can be supported. Further, on the support recess 12 of the support member 7, vertical and horizontal reinforcing bars 18 and 19 for the cloth foundation can be supported.

In the supported state of the formworks 16, 17, etc.,
As shown in FIG. 2, both leg pieces 8 of the support member 7 are located directly below each fabric foundation formwork 16 and directly support their weight.
This prevents deformation of the support piece 10, and since both the engagement pieces 9 and the fitting portion 6 are in elastic fitting engagement as described above, they will not come off due to vibrations or shocks during execution. Therefore, there is no fear that the support member 7 will fall down in the left-right direction or the front-back direction, and the formworks 16, 17, etc. can be supported in a stable state.

(Another Embodiment) Next, another embodiment of this invention will be described with reference to FIG. 5. In this embodiment, the support member 7
The support piece 21 is formed of one metal wire,
A support recess 12 is integrally formed by bending in the center thereof. Then, the horizontal leg 1 was constructed between the 8 leg pieces.
1 extends across the support recess 12 of the support piece 21,
They are welded and fixed to both sides of the recess 12, respectively. Therefore, in this embodiment, Yokogi 11
and the frame-shaped part 13 prevents wobbling and deformation,
Similar to the embodiment described above, the formworks 16 and 17 can be stably supported.

Note that this invention is not limited to the configurations of each embodiment, and can be modified and implemented as follows.

(1) As shown by the chain lines in FIG. 2, both ends of the crossbars 11 of the support member 7 are made to protrude outward from each leg piece 8, and the reinforcing bars 22 for the base part of the foundation concrete are placed on both protruding parts 11a. To be configured to support.

(2) As shown by the chain lines in FIG. 2, both ends of the horizontal beams 11 of the support member 7 are made to protrude more than the protruding parts 11a, and the ends of the protruding parts 11b are placed on the hook part 4 of the board 1. The mold plate 23 for molding the base part, which is set upright, is held from the inside.

(3) As shown by the chain lines in FIG.
shall be erected and fixed between each.

Effects of the Invention The present invention achieves the exceptional effects described below by employing the above configuration.

(1) The formwork for cloth-based concrete is directly supported by the leg pieces, and the wobbling of the supporting member is reliably prevented by the frame-like member, so that the formwork for cloth-based concrete can be supported in a stable state.

(2) Since the supporting member is placed upright by elastically fitting and engaging the engaging piece of the leg piece with the fitting part of the board, the upright placement is extremely easy and the work time can be shortened. In addition, the engagement piece will not slip out of the fitting portion due to vibration or impact during construction.

(3) Since the support members are arranged upright on the substrate as described above, the tips of the supports are easily aligned and there is no need for height adjustment.
