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 is formed in the center of the assisting device body with a flat plate protruding thereon to be inserted into the rigid bar of the reinforcing bar cage, and a gap forming piece is protruded on the opposite side of the flat plate. There is a form of

Problems that the invention aims to solve: However, with this type of structure, the hole is inserted into the rigid reinforcement and fixed from the outside with wire, etc., so it cannot be attached directly to the rigid reinforcement, and it is easy to rotate. It is difficult to fix in the required position, has serious practical drawbacks such as not having sufficient strength against the lateral pressure during concrete pouring, and does not have a sufficient dividing function. .

Means to Solve the Problems This idea was devised in view of the problems of the conventional art as mentioned above.The purpose of this invention is to securely and quickly attach the reinforcing bars of the reinforcing bar cage, and to reduce the lateral pressure during concrete pouring. It has sufficient resistance against
The purpose is to provide a pile head processing tool that has excellent workability and functionality, such as being able to finely divide the pile head, and as a means thereof, the present invention includes an edge cutting material that holds vertical bars in a reinforcing bar basket,
A mounting part is provided at an appropriate position on the mounting piece to straddle the vertical reinforcement, and a vertical split member is bent centripetally toward the center of the pile, and a ring-shaped member is provided around the lower end of the vertical split member. It is characterized by consisting of a bottom split material.

Function: For example, after holding the edge cut material on the vertical bars in the reinforcing bar cage, the vertical split material is placed across any vertical bar, and then the bottom split material is installed below it along the vertical bar.

Thereafter, the problem of the 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 a pile head processing tool.

Reference numeral 2 denotes a cylindrical edge cutting material made of an elastic material such as a foamed resin that holds the vertical reinforcement in the reinforcing bar cage.

3 is a vertically split material made of waterproof paper or synthetic resin having appropriate rigidity and elasticity, and is attached to the upper and lower parts of the approximately V-shaped mounting pieces 3a and 3a to be installed across any vertical reinforcement in the reinforcing bar cage. , multiple pieces (in this case
Attachment portions 3b of 16 (16) attachment holes are formed so as to face each other in the horizontal direction.

Reference numeral 4 denotes a bottom splitting material formed by forming a rod-shaped body made of the same material as the edge cutting material 2 into a ring shape along the outer circumferential surface of the vertical strip.

In addition, even if the edge cut material 2 and the vertical split material 3 are integrated,
Alternatively, they may be made into separate bodies, each having the same vertical dimension.

Moreover, the bottom split material 4 may be formed along the inner surface of the vertical stripes.

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

As shown in FIGS. 2 and 3, for example, after excavating from the ground surface using a drilling bucket or the like, a casing tube (not shown) is inserted.

After that, after inserting the edge cutting material 2... from above into the vertical bars T... of the reinforcing bar cage K assembled in advance in the land assembly, the top of the vertical split material 3 is inserted into the adjacent longitudinal bars T, T into the above-mentioned cheeking. Insert a wire into any mounting hole 3b to be located near the center of the tube, fix it, and attach the vertically split material 3.
The bottom dividing member 4 is attached along the outer and inner circumferential surfaces of the longitudinal strips so as to abut the lower ends of the vertical strips. Next, the reinforcing steel cage K is put into the casing tube hole, the tremor tube D is inserted into the center of the casing tube, and the tremor tube D is raised while pouring concrete to the required position (of the vertically split material 3). After the concrete has cured, the pile caps are scraped and removed using a back force shovel, etc.

Note that the installation procedure can be arbitrarily changed depending on the form.

As described above, the pile head processing tool 1 of the above embodiment can be reliably and quickly attached to the vertical bars of a reinforcing bar cage, and has sufficient resistance against lateral pressure during concrete pouring. The synergistic effect of the combination of the edge cutting material 2, vertical dividing material 3, and bottom dividing material 4 allows the pile head to be further divided into smaller sections, resulting in excellent workability and functionality.

Note that the attachment portions of the vertically divided members are not limited to the above-mentioned form, and may be set arbitrarily.

Further, it is also possible to easily assume that the shape of the vertically divided members is other than that of a U-shape or a U-shape.

Effects of the invention As explained in detail above, according to this invention, it can be reliably and quickly attached to the vertical reinforcement of a reinforcing bar cage, and also has sufficient resistance against lateral pressure during concrete pouring. The synergistic effect of the combination of edge cutting material, vertical splitting material, and bottom splitting material allows the pile head to be divided into even smaller pieces, resulting in a pile cap processing tool that is extremely effective in practice and has excellent workability and functionality. It is possible.
