Description

[Detailed Description of the Invention] The present invention relates to a support for a concrete pressure pipe.

In construction, when concrete is poured using a concrete pressure pipe within the assembled formwork, the conventional support for the concrete pressure pipe (commonly known as a horse) is inconvenient due to the complexity of the structure, or there are problems with diversion. In particular, there are disadvantages in that repairs due to adhesion of concrete slag, durability of movable parts, and direction change of concrete pipes during concrete pouring are limited.

The support stand of the present invention was made to eliminate the above-mentioned drawbacks, and the structure of the support stand of the present invention is described below as
To explain based on the drawings, the leg frame main body 1 of the support stand is a rigid member such as a steel pipe or a round bar, and the legs themselves are basically expanded to have a trapezoidal shape in order to improve stability.

The support piece 2 is integrally connected at both ends by welding or the like to the vicinity of the top of the leg frame, and is used to support a piece of batten or the like that also serves as reinforcement for the leg. Further, a horizontal member insertion opening 3 is formed between the upper surface of the leg frame body 1 and the support piece 2.

Note that 1a is a round seat provided at the end of the leg frame body to prevent damage to the formwork.

The supports for the concrete pressure pipe of the present invention having the above configuration are arranged in pairs on the horizontal members A and A in a V-shape on the left and right as shown in Figures 2 and 3.
is inserted into the horizontal member insertion hole 3, and assembled using the close contact with the horizontal member A.

With the above assembly, concrete pressure pipe B connected from the concrete pump truck is mounted and concrete is poured.

As mentioned above, since the two support stands are assembled using the horizontal members placed on them and pressed against each other, the pressure from above and the weight of the pipes applied to the horizontal members further compresses the support base. Stability will be strengthened.

Further, the shape of the horizontal member and the spacing between the supports can be freely selected as long as they are compatible with the insertion openings of the supports.

The support stand for the concrete pressure pipe of the present invention has a simple structure, so it is easy to assemble, disassemble, transport, and store.Also, the axial direction of the pipe can be changed freely by lengthening the horizontal members, so it is possible to Pouring area can be expanded. In addition, because there are few parts and moving parts, there are almost no failures, and even if vibrations in the axial direction of the concrete pressure pipe occur during concrete pouring, when horizontal members with a round cross section are used, This method is useful for practical purposes, as it allows work to be performed without damaging the pipe, and there is less vibration during concrete pouring.

Figure 4 shows the usage state when square pipes are used as horizontal members, and Figure 5 shows the usage state of Figure 4, with scaffolding boards placed parallel to both sides of the pressure pipe.
Figures 6 and 7 are perspective views showing other embodiments of the support stand of the present invention. The latter type is suitable when a single round pipe-shaped horizontal member is used.

[Scope of utility model registration request] Near the top of the leg frame body, which is formed into a trapezoid shape by bending a rigid member such as a steel pipe or a round bar, both ends of a support piece are integrally connected to the leg frame body to form a horizontal member insertion opening. Also, a supporting stand for a concrete pressure pipe, characterized in that a horizontal member is inserted over the support piece, and a pair of leg frame bodies are arranged in a V-shape from the front with a required interval on the left and right sides thereof. .
