Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a filling aid used when filling a through hole formed in a concrete skeleton.

[0002]

2. Description of the Related Art For example, a through hole formed in a concrete slab, a concrete wall, or a concrete skeleton such as a concrete beam is used for piping, wiring, and the like. Although the preliminary holes of No. 2 are provided, it is necessary to finally fill the preliminary holes with a filler such as mortar. In addition, if a design change occurs in the middle of the process or a construction error occurs, an extra through hole remains and it is necessary to backfill it.
Further, even in the through hole used for piping or the like, a large gap may occur around the periphery due to the amount of piping and wiring, and in this case, it is necessary to fill the gap.

Regarding the filling work of such a through hole,
Conventionally, a backing plate is set from the opposite side of the through hole, and then mortar or the like is filled in the through hole.
Work from both sides of the through hole was essential. Moreover, in the case of a concrete slab, the opposite side of the through hole becomes the ceiling slab on the lower floor, so the work of setting the backing plate becomes a high place work, and in the case of a concrete wall, the other work is done on the back side. In many cases, there is a structure, and in this case, there is a problem that the work of setting the backing plate becomes extremely difficult, and the workability is poor, and also a heavy burden on the operator.

[0004]

SUMMARY OF THE INVENTION It is, therefore, an object of the present invention to provide a filling auxiliary tool that enables the filling work to be performed by the work from only one side of the through hole.

[0005]

For this purpose, the present invention has an engaging portion for engaging with the edge of the through hole at one end and is opened vertically. Provided is a filling auxiliary tool including a frame body having a bottom plate support portion at the other end and a bottom plate member supported by the bottom plate support portion of the frame body.

This auxiliary filling tool is used by being fitted into the through hole in a state where the engaging portion of the frame is engaged with the end edge portion of the through hole. The bottom plate member located at the other end of the hole serves to receive the filler. Therefore, for example, in the case of a concrete slab, all the filling work can be done on the floor, and in the case of a concrete wall, the work can be done only from the front side without obstacles due to other structures. It is possible,
In any case, the workability is good and the burden on the operator is small.

The bottom plate member is provided as a separate member and is supported by the bottom plate supporting portion of the frame in order to facilitate filling of the gap of the through hole in which the pipe or the like is made. In this case, , The bottom plate member is provided with an opening according to the condition of the piping,
The bottom plate member is placed on the bottom plate supporting portion with piping or the like passing through this opening to fill the gap.

The frame body of such a filling aid is preferably formed by using a linear metal material. That is, if a linear metal material is used, it can be processed by simple bending, so it is excellent in workability, and since it does not take up an extra volume, cost can be reduced, and it also satisfies the fire resistance of remaining in the concrete skeleton together with the filler. be able to.

The bottom plate member is preferably made of a material such as glass fiber board or rock wool board which is fire resistant and easy to process. That is, when such a material is used, it is possible to easily perform the processing of the opening as described above, and it is also possible to satisfy the fire resistance when it remains in the concrete skeleton together with the frame. Further, when the backfilled through hole is reopened for new use, the reopening work becomes easy.

EXAMPLE An example of the present invention will be described below. This example is an example applied to a concrete slab. As shown in FIG. 1, the filling auxiliary tool 1 includes a frame body 2 suspended in a through hole H and a bottom plate member 3 placed on the frame body 2. Has become.

The frame body 2 is formed of a linear metal material such as wire, and is opened in the up-down direction and partly has an open side 4a. The bottom plate supporting portion 4 having a shape has a structure in which one suspension portion 5 is provided upright at each apex, and the upper end of the suspension portion 5 is bent to form a locking portion 6.

The bottom plate member 3 is made of a glass fiber board and has a disk shape corresponding to the inner surface shape of the through hole H, and a cutout portion 7 for avoiding the hanging portion 5 is provided on the peripheral portion thereof. Has been formed.

To backfill the through hole H using the filling aid 1, as shown in FIG. 2, the engaging portion 6 is engaged with the upper edge of the through hole H to penetrate the frame body 2. Hanging in the hole H,
The bottom plate member 3 placed on the bottom plate supporting portion 4 of the frame body 2 is received and filled with the filler M. As a result, the frame 2 is partially embedded in the filler M, but the bottom plate member 3 remains on the surface as a part of the ceiling slab S.

In the case of a through-hole such as a preliminary hole or a miss hole, the bottom plate member 3 may be incorporated beforehand and then the frame 2 may be hung, but a through-hole through which piping or the like is passed. In the case of holes, the frame 2 is first hung and then
The bottom plate member 3 in which the openings 8 as shown in FIG. 3 are processed according to the arrangement shape of the pipes and the like is placed on the bottom plate support portion 4 so that the pipes and the like (not shown) enter the openings 8. To insert a pipe or the like into the opening 8, a cut 9 is made along the opening 8 and a part of the periphery of the opening 8 is opened from the cut 9 as shown by an imaginary line to allow the pipe or the like to enter.

In the above embodiments, the entire frame is made of a linear metal material. However, the present invention is not limited to this. For example, only the bottom plate supporting portion or the hanging portion may be made of a strip metal plate. It is also possible to use various designs, such as a design in which the hanging portion is formed in a tubular shape. Further, when a linear metal material is used, it is convenient for supporting the bottom plate member that the shape of the bottom plate supporting portion is a quadrangular shape or a polygonal shape similar to this as in the above embodiment, but a strip-shaped metal plate is used. In the case of using, for example, a circular shape corresponding to the inner surface shape of the through hole can be designed. Further, although the above-described examples are examples of application to concrete slabs, it is needless to say that the same can be applied to concrete walls and through holes of concrete beams.

[0016]

As described above, the filling auxiliary tool according to the present invention can form the receptacle for the filling material only by engaging the engaging portion and fitting it into the through hole. Therefore,
By using this filling aid, the filling work can be performed only from one side of the through hole,
The workability can be improved and the burden on the operator can be greatly reduced.
