BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a foundation formwork structure using mesh formwork.

[0002] This type of formwork structure is used when constructing a cloth foundation for a house using concrete.

0003

2. Description of the Related Art Conventionally, plywood formwork or steel formwork has been used when constructing concrete foundations for houses.

[0004] However, since this type of formwork is used repeatedly, it is necessary to perform demolding work after the concrete hardens, making it difficult to shorten the construction period.

[0005] Therefore, it has been proposed to use a mesh formwork that is buried in concrete.

[0006] If mesh formwork is used, dismantling work becomes easier and the construction period can be significantly shortened.

[0007]

By the way, when a mesh formwork is used, due to its structure, the top level of the formwork is at the level of the concrete top level, so it is necessary to assemble it accurately.

However, since it is difficult for mesh formwork to stand up on its own, it is usually installed with multiple support columns placed next to each other and supported by these.For this reason, assembly is not easy and the formwork It is also difficult to accurately determine the top level.

The present invention has been made in view of the above-mentioned conventional circumstances, and its purpose is to provide a foundation formwork structure that allows mesh formwork to be assembled easily and quickly, and in which the top level of the formwork can be accurately set. Our goal is to provide the following.

The mesh formwork 12 is erected in two rows at appropriate intervals, and both ends of each row are fixed onto the plate 10, respectively.

The formwork structure according to the second invention includes a plate 10 for maintaining horizontal level and a mesh formwork 12.

The plate 10 is installed at the corner of the foundation of the supporting ground on which the frame is constructed.

The mesh formwork 12 is erected in two rows at appropriate intervals, and both ends of each row are fixed onto the plate 10, respectively.

The mesh formwork 12 has legs 14 at both ends, and the plate 10 has support pieces 16 (see FIG. 2) into which the legs 14 of the mesh formwork 12 are fitted.

[0017]

[Function] In the present invention, since both ends of the mesh formwork 12 are supported by the plates 10 for maintaining the horizontal level, the formwork 12
It becomes possible to accurately set the top level of the

DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the overall configuration of the embodiment, in which plates 1 for maintaining horizontal level are installed at the corner portions of the foundation of the supporting ground on which the frame is constructed and at the intermediate portions thereof.
0 is set.

[0020] Each plate 10... is precisely measured and positioned using a transit or the like so that the horizontal levels thereof are all the same.

[0021] Also, on the plate 10 is a mesh formwork 1.
2 are erected in two rows at appropriate intervals, and both ends of each row are fixed to the plate 10, respectively.

As shown in the figure, the mesh formwork 12 is assembled so that the entire framework has a rectangular shape, and a formwork 18 is attached around the mesh formwork 12 to form the bottom part of the cloth foundation. It is being

[0023] Reinforcing bars are arranged between the opposing mesh formworks 12, 12, if necessary.

[0024] Also, mesh formworks 12, 12 facing each other
The upper and lower ends thereof are connected by a spacer 20.

FIG. 2 shows the plate 1 at the corner.
0 is shown, and the plate 10 is fixed with nails, wood screws, etc. to piles 22 that are driven into the supporting ground in advance.

The plate 10 is provided with a plurality of supporting pieces 16 that stand up vertically, and each leg 14 of the mesh formwork 12 is fitted into each supporting piece 16.

FIGS. 3 and 4 show mesh formwork 12.
The configuration is shown.

Ribs 24 are formed on the mesh formwork 12 at predetermined intervals to increase its strength against bending and tension.

Legs 14 projecting downward are provided at both end portions of the mesh formwork 12 and at an intermediate portion thereof.

[0030] Also, on the side of the mesh formwork 12, supports 2 are provided.
6 are attached, and some of the supports 26 also serve as legs 14.

An upper edge material 28 is provided at the upper end of the mesh formwork 12.
However, a lower edge material 30 is provided at the lower end, and side edge materials 32 are provided at both ends.
are attached to each, which reinforces the ends and covers the ends of the mesh to improve work safety.

FIG. 5 shows the structure of the spacer 20.

Both ends of the spacer 20 have a U-shaped cross section, and grooves 34 are formed in each end.

The upper edge material 28 (or lower edge material 30) of the opposing mesh formwork 12 is fitted into both grooves 34, 34, respectively, and the distance between the mesh formworks 12, 12 is maintained constant. Ru.

FIG. 6 shows how the mesh forms 12, 12 are connected in the longitudinal direction.

The side ends of the connected mesh formworks 12, 12 are butted against each other, and the upper edge members 28, 28 of both sides are abutted against each other.
A connector 36 having a U-shaped cross section is attached so as to straddle the lower edge members 30, 30.

Furthermore, the connector 36 is fixed to both mesh formworks 12, 12 with a binding wire or the like.

[0038] Since the upper and lower end sides of the mesh formwork 12 are supported by the connecting tools 36, respectively, the mesh formworks 12, 12 can be connected without causing any level deviation.

FIG. 7 shows the connected state of the mesh formworks 12, 12 at the corner portions.

The side ends of the mesh formworks 12, 12 to be connected are abutted at right angles, and the upper edge material 28 of both
, 28 (or the lower edge members 30, 30) are connected and fixed by a connector 38 which is L-shaped as a whole and has a U-shaped cross section.

Furthermore, the connector 38 is fixed to both mesh forms 12, 12 with a binding wire or the like.

In the above embodiment, the support piece 16 is integrally formed with the plate 10 in a plate shape, but it may also be formed by fixing a round bar or a member with a rectangular cross section to the surface of the plate 10 by welding or the like. good.

At this time, the legs 14 of the mesh formwork 12 are also shaped to match this.

As explained above, according to this embodiment, the legs 14 provided at both ends and the middle part of the mesh formwork 12 are placed at a constant level on the supporting piece 1 of the plate 10.
6, the top level of the mesh formwork 12 can be set accurately, and the mesh formwork 12 can be easily assembled in a short time.

[0044] Also, mesh formworks 12, 12 facing each other
The upper and lower ends of each other are spacer retainers 10, respectively.
Since the gap between the mesh formworks 12, 12 does not widen even after concrete is poured, it is maintained constant.

[0045]

[Effects of the Invention] As explained above, according to the present invention, since both ends of the mesh formwork are fixed on the plate for maintaining the horizontal level, it is possible to accurately set the top level of the formwork. It becomes possible to easily assemble the mesh formwork in a short time.
