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, first, the ground is excavated and a groove is created according to the shape of the building, and the ground stones 1 are lined up, and then the base part formwork 2, 2 and the rising part formwork 3, 3 are placed on top of it.
is placed. At this time, the formwork supporting device 4 supports the rising formworks 3, 3 from below. The base molds 2, 2 are often placed against the mold supporting device 4. Further, in order to maintain the interval between the rising part forms 3, 3 to a predetermined width, spacing holders 5 are used above and below the rising part forms 3, 3.

The conventional formwork support device used in the above-mentioned integral casting method was not so much a device as it was a mere concrete block. However, this concrete block was heavy and not easy to manufacture, so we have been considering replacing it with metal, 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 configuration 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 top surface, and a mounting part in the center that is lower than the mounting part. The reinforcement support part is formed into a substantially concave shape by the upright part, and the upright part of the support member is rotatably attached to the support leg part,
The point is that this upright part can be moved up and down.

By providing the formwork supporting device with a function of varying the height of the formwork mounting section, positioning of the rising section formwork becomes extremely easy.

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

Figure 2 is a perspective view showing the pre-assembly state of this device.
A indicates the main body, and b and c indicate the height adjustment plates.

The main body of the formwork support device of the present invention has already been proposed, and is characterized in that the support member 8 is rotatable with respect to the grounding member 7, and both ends of the grounding member 7 are cut and raised to provide support legs. 9, the base thereof is provided with a rotation elongated hole 11 into which a rotation shaft 10 of the support member 8, which will be described later, is fitted, and the tip thereof is provided with a fixed notch that fits when the support member is erected. 12 are provided. Furthermore, this support leg portion 9 has adjustment plate support cut-and-raised pieces 14 at one upper position and two lower positions for slidingly supporting the height adjustment plate 13 shown in FIG. 2 b or c from side to side. It is provided.

When the support member 8 stands upright with respect to the grounding member 7 as shown in FIG. A reinforcing support part 16 for supporting the arrangement 6 at a lower position than this mounting part and upright parts 17 and 1 at the left and right ends.
7 to form a substantially concave shape, and the upright lower ends are respectively bent outward to form rotating shaft portions 10, 10, which adjust the overall shape. The entire support member 8 is preferably formed by processing a metal bar, but the formwork mounting parts 15, 15 and the reinforcement support part 16 may be made of angle iron or flat iron. There is no problem.
Similarly, members of various shapes can be used below the upright portion 17, but a round bar or a round pipe is preferable.

As shown in FIG. 2a, the main body of this device is that before assembly, the support legs 9, 9 raised from the grounding member 7 do not stand up completely and lie flat, and the support member 8 is also similar. Since it is laid down on its side, the entire device is flat and convenient for storage and transport.

In this device, after the supporting member 8 of the rotary main body is erected, the height adjusting plate 13 of FIG. 2 b or c is cut and raised as shown in FIGS. 3 and 4. 1
4, and the rotating shaft portion 10 is also inserted into the slanted elongated hole 18 or the stepwise slanted elongated hole 19 of the height adjustment plate 13 to assemble. The support member 8 is firmly supported by its own elastic force and the elastic force of the support legs 9,
It never comes off from the fixed notch 12.

The height of the support member 8, that is, the formwork mounting portion 15
The height is adjusted by moving the height adjustment plate 13 from side to side, as shown in FIG. The lower edge of the height adjustment plate 13 may be smooth, but if it is made uneven as shown in FIG. 2c, and the grounding member 7 side is also provided with unevenness so that the two engage, the risk of slipping is completely eliminated.

Another example of height adjustment is as shown in FIGS. 5 to 9, in which the upright portion 17 is divided into two parts 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. In FIG. 5, a clamping fitting 20 is welded and fixed to the upright part 17a on the support member side, and the upright part 17b on the formwork mounting part is inserted into this and fixed by tightening with a screw 21 provided in the fold of the clamping fitting. Fig. 6 shows a nut 2 inside the C-shaped fastening fitting 22.
3 is welded, the inside of the tip is welded to the support member upright part 17a, the formwork mounting part side upright part 17b is inserted into the inside, and the screw 21 of the nut 23 is tightened and fixed. This shows a type in which a free clamping fitting 20 is tightened and fixed using a nut 23 in addition to the screw 21 shown in FIG.

The examples shown in FIGS. 8 and 9 consist of a combination of a round bar, a pipe, and a set screw, and 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 bars, especially the upright parts.
It also serves as a formwork support device that can be rotated and stored.
