Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing hole-filling concrete used for filling holes formed on the surface of a concrete wall or the like by extracting wood concrete.

When forming a concrete wall, generally, wooden frames are placed opposite each other, these are fixed with separators made of bolts and nuts, concrete is poured between the opposing wooden frames, and after the concrete has hardened, the nuts are removed and the wooden frames are replaced. Add or remove
The bolts protruding from the concrete wall are folded in, but the bolts are exposed on the concrete wall and look unsightly, so the concrete wall needs to be overcoated.

For this reason, recently, when constructing concrete walls, etc., the bolts that will serve as separators are placed inside the civil engineering frame in advance.
In order to pour concrete in this state (Fig. 1), after the concrete has hardened, place the wooden concrete frame C.
, and break off the bolt a protruding from the surface of the formed concrete wall d in the hole e formed by the wood conduit C on the concrete wall d at a position where it does not protrude from the surface of the concrete wall d. , After this, a mortar-made hole filler g is inserted into the hole e, with a comb having approximately the same external dimensions as the wood cone C, and an insertion hole f formed in the center of the insertion surface into which the bolt a protruding from the concrete wall d is inserted. Measures were taken (Figure 2).

However, since the fill-in condenser g used here is not sufficient for the work, the inventor has developed a third method prior to filing this application.
We have developed a fill-in-the-blank controller 1 as shown in the figure.

This hole-filling comma houses a capsule 3 containing adhesive in the bolt insertion hole 21. By inserting a bolt into this capsule 3, the adhesive inside the capsule 3 is pushed outward, and the hole-filling comma 1 is inserted into the concrete. It is intended to be adhered to holes in walls, etc.

Reference numeral 4 designates a protrusion provided on the outside of the capsule 3 to prevent the capsule 3 from being pulled out from the main body of the filling container 1, and 5 represents a lid of the capsule 3.

The present invention is a method of manufacturing the above-mentioned hole-filling container 1, and an embodiment of the present invention will be described in detail below with reference to FIG.

In order to form the hole-filling container 1, a mold 6 formed in the shape of the hole-filling container 1 is covered with an inner frame 1 formed in the same shape as the shape described above with a thin film made of synthetic resin.

A support portion 8 protrudes upward at the center of the bottom of the middle frame 7, that is, at a position located in the bolt insertion hole 2 formed in the hole filler 1.
(Figure 4A).

Next, the capsule 3 is placed upside down on the support portion 8 of the middle frame 7.

This capsule 3 contains an adhesive, and is provided with a lid 5 to prevent the adhesive from flowing out.

Next, mortar or concrete 9 is poured into the middle frame 7 (FIG. 4B), and after the mortar or concrete 9 has solidified, the middle frame 7 is taken out from the mold 6 (FIG. 4C).

Therefore, the inner frame γ is taken along with it to the work site, and the hole-filling container 1 is taken out from the inner frame 7 and used each time hole-filling work is performed.

Since the present invention has the above-mentioned configuration, the capsules are housed at the stage of pouring mortar etc. into the mold, so there is no need to fill the capsules after the molding of the hole filler 1, which simplifies the manufacturing process. Since the entire inner frame can be taken out from the container, it can be carried to the work site while still in the inner frame, making it easier to transport, handle, and calculate the number of pieces.Furthermore, since it can be carried while still in the inner frame, there is no need to fill holes during transportation. It is possible to prevent the corners of the concrete from chipping or cracking, and for this reason, it is now possible to use concrete rings instead of the ones that conventionally had to be made of mortar.It is an excellent method for producing hole-filling concrete used for filling holes in concrete walls, etc. It has a positive effect.

Claims (1)

[Claims] 1. To form a fill-in container, a synthetic resin inner frame formed in the same shape is placed in a formwork formed in the shape of a fill-in container, a capsule containing an adhesive is placed in this inner frame, and then the inner frame is A method for manufacturing a hole-filling concrete for use in filling holes in concrete walls, etc., characterized in that mortar or concrete is poured into the mold, and after the mortar or concrete has solidified, the inner frame is taken out from the form.
