Description

[0001]
[Industrial application fields]
The present invention relates to a technique capable of easily forming a mold frame simply by arranging a frame plate when building a concrete foundation such as a house.
[0002]
[Prior art]
The basic concrete has a substantially inverted T-shaped cross section, and this basic concrete is formed by pouring concrete into a predetermined formwork. In this case, the base frame is made of a base concrete with a plywood board arranged vertically at a predetermined interval, and a concrete form is poured on the base frame by setting up a rising base frame having a narrow interval. Therefore, the base and the rise must be created separately, and not only the assembly work of the above-mentioned formwork is troublesome, but also the production of the formwork and the concrete as compared with the case where the foundation concrete is made at once. The number of man-hours required for the pouring work will be doubled.
[0003]
In recent years, the entire surface under the floor is used as a concrete surface to prevent moisture from rising from the ground (moisture-proofing) and to prevent the occurrence of white ants by performing moisture-proofing treatment. Therefore, in this case, after the foundation concrete is created, a concrete surface is created on the ground, and the concrete pouring operation is performed three times.
[0004]
[Problems to be solved by the present invention]
Thus, the conventional foundation concrete formwork has the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a formwork structure of a basic concrete that allows easy assembly of a formwork and requires only a single pouring operation of concrete.
[0005]
[Means for Solving the Problems]
In the present invention, the cross-sectional shape of the foundation concrete is not an inverted T-shape, but a cross-sectional shape having an L-shape, and the mold frame has a structure capable of creating the foundation concrete having an L-shaped cross-section. Therefore, a support column is erected vertically at one end of the base, and a receiver is attached to the support column so as to be movable up and down, and the receiver can be fixed at a predetermined height. A frame plate is placed on and supported by the receiver.
[0006]
Also, 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 become a horizontal portion. It is provided and a screw is formed. Accordingly, another frame plate facing the frame plate is attached to the horizontal portion. In order to support the horizontal portion of the mounting member, a support rising from the base is welded in the middle. The foundation building muscle frame is supported on the mounting member.
[0007]
In this way, the two frame plates parallel to each other are erected vertically, but the frame plate located on the inner side is supported by the receiver, so that a space is left far from the base. Concrete is poured between the two frame plates, but the concrete flows out from the space left below one of the frame plates to form a concrete layer on the lower surface of the floor. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0008]
【Example】
FIG. 1 is a specific example showing a cross section of foundation concrete to which the present invention is applied. A concrete layer 3 is formed between the foundation concrete 1 located outside and the foundation concrete 2 located inside. This concrete layer 3 suppresses moisture under the floor as much as possible, and the building is not affected by pests such as white ants, and the air tightness and heat insulation under the floor are enhanced.
[0009]
When building the above-mentioned basic concrete 1 and 2 and the concrete layer 3 under the floor, the frame plates 4a, 4b, 5a and 5b are attached to the holder, and the concrete is poured into the space between the frame plates 4a, 4b and 5a and 5b. It is. Accordingly, at the same time, the above concrete layer 3 is formed in addition to the two basic concretes 1 and 2, and is completed by a single frame and concrete pouring operation. In the present invention, since the foundation concrete 1 is a target, the formwork structure for creating the foundation concrete 2 is not particularly limited. For example, the formwork structure of the foundation concrete according to the patent application dated June 17, 1995 is used. I can do it.
[0010]
By the way, the holder which attaches the form for creating the foundation concrete 1 is shown in FIG. In the figure, 6 is a base, 7 is a support column, 8 is a receiver, and 9 is a mounting member.

[0011]
The base 6 is a U-shaped member having standing edges 11, 11 on both sides, and the support column 7 is welded to the bottom surface 12 of the base 6 to stand upright. The guide rod 13 extending below the receiver 8 can be loosely fitted and moved up and down, whereby the height of the receiver 8 can be freely changed. The receiver 8 has a U-shape and is attached with the frame plate 4b shown in FIG.
[0012]
On the other hand, the attachment member 9 has an L-shaped bent shape having a vertical portion 14 and a horizontal portion 15. The vertical portion 14 is welded to the base bottom surface 12 and stands up. It is supported by being welded to a support bar 16 standing up from the base bottom surface 12. A flange 17 is provided at the tip of the horizontal portion 15, and a screw is formed at the tip of the flange 17. The frame plate 4a shown in FIG. 1 is positioned and attached to the flange 17 of the horizontal portion 15. The lower end of the frame plate 4a is positioned on the base 6 and abuts against a contact surface 20 of a notch 19 formed at one end. Therefore, the contact surface 20 is formed on the same vertical surface as the flange 17, and the frame plate 4a is vertically arranged upright.
[0013]
FIG. 3 shows a case where both frame plates 4a and 4b are attached to the holder of the present invention. One frame plate 4a is positioned against a notch 19 formed in the base 6, and is fixed by being sandwiched between a flange 17 of the horizontal portion 15 and a fastening member 21 made of a bar material. One frame plate 4 b is supported by being placed on a receiver 8, and a reinforcing bar 22 is placed on the same receiver 8. And the connecting rod 23 is spanned by the upper end part of both frame board 4a, 4b. Thus, the frame plate 4b is placed on the support 8 and a large space is left between the frame 6 and the concrete poured from the upper portions of the frame plates 4a and 4b flows from the lower space of the frame plate 4b. The concrete layer 3 under the floor shown in FIG.
[0014]
The foundation building bar frame 24 is arranged between the two frame plates to form the foundation concrete. The foundation building bar frame 24 is placed on the horizontal portion 15 of the mounting member 9. . Then, it is positioned in contact with the support bar 16 that supports the horizontal portion 15. FIG. 4 is a specific example showing the foundation construction muscle frame 24.
