Description

[Detailed explanation of the invention] Industrial application field This invention is used for concrete pouring,
This invention relates to a pile cap processing tool for cast-in-place piles used when processing pile caps after curing.

Conventional technology This type of pile head treatment tool was developed in 1983.
As described in Publication No. 76635, a hole to be inserted into the vertical bar of the reinforcing bar basket is formed in the center of the assist tool body with the flat plate protruding thereon, and a gap forming piece is protruded on the opposite side of the former flat plate. There is a form that consists of

Problems that the invention aims to solve: However, with this type of structure, the hole is inserted into the vertical bar and fixed from the outside with a wire, etc., so it cannot be attached directly to the vertical bar, and it is easy to rotate. It is difficult to fix it in the required position, it does not have sufficient strength against the lateral pressure during concrete pouring, and different sizes are required depending on the diameter of the reinforcing bar cage, which is extremely difficult in practical terms. is unreasonable.

Means for Solving the Problems This invention was devised in view of the conventional problems as described above, and its purpose is to ensure that the vertical bars of the reinforcing bar cage are fixed regardless of the shape and diameter of the reinforcing bar cage. To provide a pile head treatment tool that can be quickly installed, can be divided into any shape on site, and has excellent workability and functionality, such as being able to withstand sufficient lateral pressure during concrete pouring. As a means for this purpose, a continuous thin plate-like mounting plate having mounting holes formed therein is wound to be fixed to the vertical reinforcement of the reinforcing bar cage.

Function: A mounting plate cut to an appropriate size to match the diameter of the reinforcing bar cage is attached to, for example, a vertical bar in the reinforcing bar basket in a planar triangular shape, and then continuously wrapped around the outer periphery of the vertical bar.

After that, the problem of the earlier conventional product is solved by putting the reinforcing bar cage into the pile hole and inserting the reinforcing pipe.

Embodiments Hereinafter, embodiments of this invention will be described in detail based on the drawings.

FIG. 1 is a perspective view of a pile cap processing tool according to an embodiment of this invention.

1 is the mounting hole 2 to be fixed to the vertical reinforcement in the reinforcing bar cage.
A continuous thin plate-like mounting plate 2 having appropriate rigidity made of synthetic resin or the like, with holes vertically arranged in parallel.
This is a pile head processing tool made by rolling.

Pile head processing tool 1 of an embodiment configured as described above
An example of its use is described below.

As shown in FIG. 2, for example, after excavating from the ground surface with a drilling bucket or the like, a casing tube (not shown) is driven in.

After that, the mounting plate, which has been cut to an appropriate size to match the diameter of the reinforcing bar cage, is attached in a planar triangular shape to the vertical bar T into which the cylindrical edge cutting material E of the reinforcing bar K, which has been assembled by the land assembly, is inserted. A wire or the like is inserted into the mounting holes 2a and fixed, and similarly the wire or the like is continuously wound around the outer periphery of the vertical reinforcement.

Next, the reinforcing bar K is put into the casing tube hole, the tremor tube D is inserted into the casing tube in the center, and while pouring concrete, the tremor tube D is raised to fill it to the required position, and the concrete is cured. After that, use a back force shovel, etc. to crack and remove the pile cap.

As described above, according to the pile head processing tool 1 of the above embodiment, the dimensions can be set freely regardless of the shape and diameter of the reinforcing bar cage, and it can be quickly attached to the vertical bars of the reinforcing bar cage, and it can be installed at the site. Can be divided into any shape,
It has excellent workability and functionality, such as being able to withstand sufficient lateral pressure during concrete pouring, and is extremely effective in practice.

It should be noted that it is also possible to easily consider making the pile cap treatment tool in the above embodiment into another form, for example, a mesh-like mounting plate wrapped around it.

In addition, as another usage condition, the vertical bars of the reinforcing bar basket may have any shape such as a rectangular shape or a hexagonal shape in plan view.

Effects of the invention As explained in detail above, according to this invention, regardless of the shape and diameter of the reinforcing bar cage, it is possible to set the dimensions freely, and it can be attached to the vertical bars of the reinforcing bar cage reliably and quickly. , a pile head treatment that is extremely effective in practice, with excellent workability and functionality, such as being able to be divided into arbitrary shapes on site and providing sufficient resistance against lateral pressure during concrete pouring. You can get the ingredients.
