Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting device for mutually connecting temporary supports in temporary shoring or the like with a connecting material.

[Conventional technology]

For temporary shoring to support slab formwork and beam formwork of buildings, etc., temporary supports made of steel pipes with trestles and jacks are used, and many of these are erected and connected to each other with tie materials to construct shoring. I am trying to configure it. Conventionally, the temporary supports are connected to each other by attaching a steel pipe clamp to the temporary support and tightening a steel pipe connecting member to the clamp.

[Problem that the invention attempts to solve]

In this method of connecting temporary supports, it is necessary to tighten the connecting materials while maintaining each temporary support vertically, which not only requires a lot of manpower and is troublesome, but also reduces the support structure. There are many problems, such as the possibility that temporary construction cannot be done reliably and firmly.

The present invention eliminates these shortcomings of conventional shoring, and provides a temporary support that can be easily and reliably connected to each other without requiring any effort, and that allows temporary support to be installed firmly, efficiently, and economically. It is intended to provide a coupling device.

[Means for solving problems]

The structure of the present invention will be explained with reference to the drawings corresponding to the embodiments.
The side plate 4 is formed at a plurality of positions spaced apart along its length, and has receiving portions 9 that are roughly U-shaped and expand upward at the bottom thereof, and have wedge holes 5 on both sides thereof. A receiving bracket 2 with a protruding
2, and a receiving space 6 is formed between the receiving part 9 and the support main body 1, and a rod 7.
An engaging portion 9 that fits into the receiving cavity 6 is provided on both sides of the
A connecting material B formed by fixing the insertion fittings 8, 8 provided with the above-mentioned insert fittings 8, 8 is inserted into the wedge holes 5, 5 of the receiving fitting 2 to prevent the insertion fitting 8 fitted into the receiving space 6 from coming off. It is characterized by consisting of a wedge 11.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In the figure, A is a temporary support, which is formed by a support main body 1 made of, for example, a steel pipe with a circular cross section, and metal fittings 2, 2 each provided at a plurality of positions spaced apart along the length of the support main body 1. ing.
The connecting fittings 2, 2 at each position are provided in the same direction on all four sides of the cross section.

The receiving fitting 2 is formed into a roughly U-shape, and its lower part is formed into a receiving part 3 that expands upward, and side plates 4, 4 extend upward from both upper ends of the receiving part 3. Wedge holes 5 are provided in the side plates 4, 4 to allow the wedges 11 to pass through them.
5 is provided. Each of these brackets 2 is fixed to the support main body 1 by welding,
A receiving cavity 6 (see FIG. 4) is formed between the receiving portion 3 and the outer surface of the column main body 1, and extends upward.

Reference numeral B denotes a connecting member that connects the erected temporary supports A, A, and has a structure in which insert fittings 8, 8 are fixed to both ends of a rod 7 made of pipe material or the like. The insertion fitting 8 has a tapered engagement part 9 protruding from the lower part thereof, which has a similar shape and fits into the receiving space 6 formed between the receiving part 3 of the receiving fitting 2 and the support main body 1.
A wedge receiving protrusion 10 is provided at the upper end.

As shown in FIGS. 6 and 7, the temporary support A and the connecting material B are assembled by inserting the insertion fittings 8 and 8 into the receiving metal fitting 2 provided on the temporary support A from above, and inserting the insertion part 9 into the receiving metal fitting 2. After fitting into the cavity 6, the wedges 11 are inserted into the wedge holes 5, 5 of the receiving metal fitting 2, and the insertion fittings 8, 8 are held down to prevent them from coming off, thereby making the connection. The connection can be easily released by removing the wedge 11 and pushing the insertion fitting 8 upward.

FIG. 1 shows a general example of shoring using the device of the present invention. A height adjustment jack 12 is attached to the lower end of the temporary support column A, and a height adjustable drop jack 13 is attached to the upper end. These temporary supports A, A are arranged and erected vertically and horizontally at the required intervals, and as mentioned above,
They are connected to each other by connecting materials B and B. Connections using the connecting material B can be made in appropriate numbers at appropriate locations by using any of the receiving metal fittings 2, 2 provided on the temporary support support A. As a result, the strength
A column-connected structure with high rigidity can be formed. Drop jacks 13, 13 at the upper ends of temporary supports A, A
A beam material 14 that supports the slab formwork 15, a girder material (not shown) that supports the beam formwork, and the like are supported between them. When concrete is poured and the formwork is removed after hardening, the drop jack 13 is lowered to separate the beam material 14 and the slab formwork 15 from the concrete.

[Effect of idea]

As explained above, the device of the present invention has a generally U-shaped receiving portion formed at multiple positions spaced apart along the length of the main body of the support, and the receiving portion is expanded upward at the bottom. At the same time, a receiving metal fitting having a side plate with a wedge hole projecting thereon is fixed to both sides thereof, and a receiving space is formed between the receiving part and the main body of the post. A connecting material made by fixing an insert fitting provided with an insertion part that fits into a receiving cavity, and a wedge that is inserted into a wedge hole of the receiving fitting to prevent the insert fitting fitted into the receiving cavity from coming out. Therefore, the work to connect the temporary supports to each other involves placing a connecting material between each temporary support and fitting the insert into the receiving metal fitting of the temporary support. By inserting a wedge to prevent the material from falling out, it can be made extremely simple, reliable, and strong, and the temporary construction of shoring can be done efficiently and economically. In addition, since the brackets can be fixed at appropriate locations in the length direction and circumferential direction of the temporary support, it is possible to freely set and connect the points necessary for connecting the temporary support, and to connect the temporary support. It has many advantages, such as being able to be used not only for connections but also for temporary construction such as scaffolding.
