Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a variable height support device for supporting the rising part formwork of a cloth foundation of a building such as a house at an appropriate height from the lower part.

For cloth foundations, the concrete pouring method in which the base and rising parts are constructed at the same time is becoming more common in order to shorten the construction period and increase the strength of the foundation. Figure 1 shows an example of the construction method in this case. In the one-piece construction method, the ground is first excavated and a groove is created according to the shape of the building, then the ground stones (1) are lined up, and then the base part formwork (2) and the rising part formwork are placed on top of it. (3) (3'l is placed.At this time, the formwork support device (4) supports the rising part formwork (3) (3'l) from the bottom.The formwork support device (4) In many cases, the base formwork (21(2)) is placed against the base formwork (21(2)).In addition, in order to maintain the interval between the rising formworks (3)(3) at a predetermined width, the rising formworks (3)(3) ) at the top and bottom of the space retainer (
5) is used.

The conventional formwork support device used in the above-mentioned integral casting method was not so much a device as a simple concrete block. However, this concrete block was heavy and not easy to manufacture, so we added a ridge to replace it with a metal one, and have made many proposals so far.

The formwork supporting device of the present invention is characterized in that the formwork mounting part is a rotating type that is made of metal and is easy to manufacture, transport, and handle, and the height is variable, thereby doubling the convenience of use. It is something.

The gist of its structure is that it consists of a metal grounding member and a support member.The grounding member forms support legs on both sides, and the support member has a formwork mounting part on the left and right sides of the upper surface and a middle-heat mounting part. The upright part of the support member is rotatably attached to the support leg, and the upright part is movable up and down.

By providing the formwork supporting device with a function of varying the height of the formwork mounting section, the positioning of the rising section formwork can be easily set.

Hereinafter, the present invention will be specifically explained with reference to drawings.

FIG. 2 is a perspective view showing the device before assembly, in which (a) shows the main body, and (b) and (Q) show the height adjustment plate.

The formwork supporting lid main body of the present invention is characterized by the already proposed structure, in which both ends of the ground contact part (7) are cut and raised to form support legs (9), and the base thereof A rotary elongated hole 01) for fitting the rotary shaft portion 0 ( ) of the support member (8), which will be described later, is provided at the tip, and a fixed notch (2) that fits when the support member is erected is provided at the tip. It is provided.

Furthermore, this support leg (9) has a structure shown in FIG. 2(b) or (a).
Adjustment plate support cut and raised pieces 04) for slidingly supporting the height adjustment plate 03 shown in ) from side to side are provided at one location above and at two locations below.

The support member (8) has a formwork mounting part 0h0υ on which the rising part formwork is placed on the left and right when it stands upright on the grounding member (7) as shown in Fig. 1 or Fig. 6. Reinforcement support part O for supporting reinforcement (6) at a lower position than the mounting part in the center of and.
Q is formed into a substantially concave shape with upright parts 0ηαη at the left and right ends, and the lower upright ends are bent outward to form a rotation shaft part 0().
The overall shape is arranged as αQ. This support member (8)
It is preferable that the whole be formed by processing a metal support.
The formwork mounting part (15105 and the reinforcement support part 0 part may be made of angle iron or flat iron. Also, members of various shapes are used in the same way from the upright part Q to the lower part. Yes, but round rods or round pipes are preferred.

As shown in Fig. 2(a), the main body of this device consists of support legs (9) that extend beyond the grounding part (7) before assembly. , and the support member (8
) can also be laid down on its side, so the entire device is flat and convenient for storage and transport.

After the support member (8) of the rotatable main body is erected in this way, this device is operated as shown in FIG. 2C as shown in FIGS.
b) or (C), insert the descendant peg plate 0 [present] between the cut and raised pieces Q4, and attach the rotating shaft member to the height adjustment plate (13, long slanted length 08) or the stepped slanted elongated hole 0 Insert it into the slot and assemble it. The support member (8) has its own elastic force and support legs (
It is firmly supported by the elastic force of 9) and will never come off from the fixed notch @02.

The height of the support member (8), that is, the height of the formwork mounting portion 0υ, can be adjusted using the height adjustment plate α as shown in Fig. 4.
Due to side-to-side movement. The lower edge of the height adjustment plate 0] may be smooth, but it should be made uneven as shown in Figure 2 (C).
) side as well so that the two sides interlock, there is no risk of slipping and there is no risk of force.

Another example of height adjustment is as shown in FIGS. 5 to 9, in which the upright portion α is divided into two parts and is of a sliding type, and the height adjustment is performed using a clamping metal fitting or a screw. Although these are normally used as a mechanism for expanding and contracting rods, they can be applied to adjust the height of the rotary formwork support device of the present invention to give favorable results. Fig. 5 shows a clamping bracket being welded and fixed to the upright part (17a) on the right side of the support part.
A type is shown in which the upright part (17b) on the side of the formwork mounting part is inserted and fixed by tightening with a screw (C) provided in the fold of the clamping bracket. Natsuto inside (Ha)
Weld the inside of the tip to the support part (17a"+), insert the formwork part side upright part (17b) inside, and tighten with the nut (to) screw 41). The fixing type is shown in Figure 7, in addition to the fifth screw 01), nuts (c) are used.
Indicates the type in which the free clamping fitting (A) is tightened and fixed.

The examples shown in FIGS. 8 and 9 consist of a combination of a round bar, a pipe, and a set screw, and there are two examples in which the round bar and pipe are reversed.

The reason why the height can be adjusted with such a simple means is because the support members are made of rods, especially the upright parts, which allows for variable height of the fabric foundation formwork, which is unprecedented, and rotational storage. It is a possible formwork support device.
