Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Field of Application The present invention relates to an auxiliary body used when grouting a wall to a floor slab or the like in a high-rise residential building or other building.

(2) Prior Art Conventionally, for example, when grouting the opening between the lower end of a prestressed concrete (PC) load-bearing wall and the side edge of a floor slab, the PC version load-bearing wall (a) is used as shown in Figures 5 to 7. A cylindrical body (C) called Esaform (registered trademark) is continuously inserted into one side edge of the gap between the floor slab (b) and the gap between the floor slab (b) and a similar Esaform ( d) is interposed at predetermined intervals with gaps (e), and further the gaps (e)
A semi-cylindrical grout inlet (f) made of tin plate is fixed on the floor slab (b) on the side of the spot with mortar, etc., and the grouting agent (for example, mortar) is g) to the PC version load-bearing wall (a) and floor slab (
b) It was injected into the gap between.

(Part 3 Problems to be Solved by the Invention) According to this conventional grout, in order to fix the tin plate of the grout inlet (f) with mortar etc.
), the grouting agent must be injected at a later date and time, which takes time, and furthermore, when injecting the grouting agent (g), the semi-cylindrical grout inlet (f) and 11? A part of the grouting agent (g) leaks to the outside from between the Esaform Cd) and the floor slab (b), and the grouting agent (g)
After curing, it is necessary to remove the hardened grout by removing the semi-cylindrical injection port (f), which is a time-consuming problem.

It is an object of the present invention to solve these problems and to provide a grout auxiliary body that does not cause leakage of the grouting agent when the grouting agent is injected, and does not require the labor required for grouting.

(4) Means for Solving the Problems In order to achieve this object, the present invention is a prismatic body made of synthetic resin, with notches formed on its side surfaces, these notches forming grout inlets, and both surfaces on the bottom surface. It is characterized by being attached with adhesive tape.

(5) Function The grout auxiliary body is attached to the upper surface of a floor slab or the like using the double-sided adhesive tape so that its side surface is in contact with the lower end of a load-bearing wall, etc., and the grouting agent is injected from the injection port to It is possible to grout between the lower end of a load-bearing wall, etc. and the upper surface of a floor slab, etc., thus eliminating the conventional effort of removing hardened grout by peeling off, and greatly improving work efficiency. No more leaking onto the upper surface of floor slabs, etc.

(6) Example One example of the grout auxiliary body of the present invention will be described with reference to FIG.

(1) indicates a grout auxiliary body, and the grout auxiliary body (1)
) is made of a prismatic body made of hard urethane rubber or other synthetic resin, and notches with an inclined bottom surface are formed at regular intervals on one side of the prismatic body as shown in the first figure, and these notches are used as grout injection ports (2 )...(2) was formed, and double-sided adhesive tape (3) was further attached to the lower surface.

Next, grouting using the grout auxiliary body (1) of the above embodiment will be explained according to FIGS. 2 to 4.

First, the cut groove at the lower end of the 20th edition load-bearing wall (4) and the floor slab (
1 of the gap (8) formed by the cut groove on the side edge of 5).
Aceform (6) is interposed on the side edge, and the grout auxiliary body (1) is placed on the upper surface of the floor slab (5) on the side of the other side edge.
is adhered to its lower surface using double-sided adhesive tape (3). At this time, one side of the grout auxiliary body (1) is brought into contact with the wall (4). Thereafter, a grouting agent (7) made of, for example, mortar is injected through the injection ports (2)...(2) of the grouting auxiliary body (1), and the gap (8) is filled with the grouting agent (7). Furthermore, after injecting grout, each grout inlet (2) is covered along the wall surface with a metal plate (9), etc. At the time of this injecting, the grout auxiliary body (1) is integrated and attached to the floor slab ( 5
), so the grout agent (7) will not leak out, and a joint is formed with the grout auxiliary body (1) fixed by hardening of the filled grout agent (7) mentioned above. . In this way, there is no need for the conventional effort of peeling off the hardened grout (7).

(7) Effects of the Invention According to the present invention, the grouting auxiliary body is formed of a prismatic body made of synthetic resin with a cutout for the grout inlet formed on the side surface and a double-sided adhesive tape attached to the bottom surface. , the grouting auxiliary body is attached to the upper surface of a floor slab or the like with the double-sided adhesive tape so that its side surface is in contact with the lower end of the wall, etc., and the grouting agent is injected through the injection port to attach the grouting agent to the load-bearing wall, etc. It is possible to grout between the lower end and the upper surface of a floor slab, etc., and since the metal is inserted into the injection port, the labor of removing hardened grout by peeling off, as in the past, can be omitted, greatly improving work efficiency. This has the effect of preventing the grouting agent from leaking onto the upper surface of the floor slab etc. during grouting.
