Abstract

PURPOSE:To maintain the high strength of a concrete wall in the periphery of a buried body by providing a mounting section set to the rear of the buried body to about the center of a sheet of plate material, and providing erection sections having through-holes to the sides to form an erection implement. CONSTITUTION:An erection means 10 is constituted of a mounting section 11 on about the center of a plate material and erection sections 13 forming through- holes 12 on the both sides of the mounting section. A claw 14 fixing a buried body B and an avoidance section 15 avoiding knockouts 20 are provided to the mounting section 11. After that, the buried body B is mounted with the claw 14 of the mounting section 11, and the erection section 13 is bound to reinforcing bars 30 with wires 35. According to the constitution, concrete is solidified through the through-holes 12, and the erection implement 10 and a concrete wall are fixed together as a unit to the wall into which the buried body B is buried by means of the erection implement 10, so that a decline in the strength of the wall can be prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an erection tool for a concrete buried object.

(Prior art) Conventionally, in order to fix a buried concrete object such as an electric wiring box to the support steel reinforcement, the buried object (B) is fixed as shown in Fig. 8.
An erection tool (8
0) is known.

(Problems to be Solved by the Invention) Generally, when a buried object is buried in a concrete wall, the strength of the surrounding wall decreases, but the above-mentioned conventional erection tools have no problems in this respect. It wasn't taken into account.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a construction tool for a concrete buried body that can maintain high strength of the concrete wall on the side of the buried body.

(Kth Means for Solving the Problems) In order to solve the above-mentioned problems, the erection tool for a concrete buried object according to the present invention includes a mounting part that is provided approximately in the center of the board and attached to the back surface of the buried object; It is characterized by comprising a construction part having a through hole provided on the side of the mounting part.

(Function) With the above-described configuration, the erection tool for this concrete buried object is installed by punching out a plate, etc., and in order to use this erection tool to erect the buried object to the support steel reinforcement of the concrete wall, the installation tool must be attached to the mounting part. All you have to do is attach the box and tie the construction part to the reinforcing bars with wire.

In the wall buried by this construction tool, the concrete in front and behind the construction tool hardens through the through hole, so that the construction tool and the concrete wall are strongly tied together.

(Example) Hereinafter, an example of an erection tool for a concrete buried body embodying the present invention will be described with reference to the accompanying drawings.

As shown in Figs. 1 and 2, the erection tool (10) for this concrete buried body consists of a mounting part (11) that is provided approximately at the center of the board and attached to the buried sports surface, and a mounting part (
! A through hole (
12) and an erection section (13).

Therefore, the erection tool (10) for this concrete buried body is
Easy to do by punching out the board! ! ! However, it may be manufactured by other methods. The construction part (
13) can be bent by hand and has a tensile strength that allows the buried body (B) to be pressed against a formwork (50) to be described later.

The mounting part (It) is attached to a buried body (such as an electrical wiring box).
B) is provided with a cut-and-raised claw (14) for fixing it. Furthermore, the attachment part (11) is provided with an avoidance part (I5) that is transparent in order to avoid blocking the knock ring (20) formed at a predetermined position on the back surface of the buried object (B). There is. Note that this avoidance section (15) may be provided as necessary and may be omitted.

Next, the operation of the erection tool (10) for this concrete buried body will be explained.

In order to erect the buried body (B) to the supporting steel bars (30) of the concrete wall using this concrete buried body erection tool (lO), first, use the claws (14) of the concrete buried body on the mounting part (11). Then, as shown in FIG. 1, the construction part (13) may be tied to the reinforcing bar C30) with a wire (35). At this time, the buried physical education surface is knocked out) (
20) with the avoidance part (15), it is possible to connect the connector and the electric conduit (45) not only to the side surface but also to the knockout (20) on the back surface and wire it to the buried body (B). After wiring, formwork (50) is erected before and after the buried body (B), and concrete is poured. In addition, as shown in Fig. 3, the construction part (13) is bent appropriately according to the distance between the reinforcing bar (30) and the formwork (50), and the buried body (B) is placed in the formwork (50).
Press it down and make it come into contact with it so that it is stretched.

When the construction tool (lO) is used to bury the buried object (B) in the wall, the concrete in front and behind the construction tool (10) hardens through the through hole (12), so that the construction tool (10) and the concrete wall are hardened. are strongly tied together. Therefore, even if the buried body (B) is buried, a decrease in the strength of the wall can be prevented.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and if the mounting portion (11) is provided with two pairs of cut-and-raised claws (14) as shown in FIGS. (B)
Attach the erection tool (10) diagonally to the
It can also be fixed to 0). Therefore, even when the interval between the reinforcing bars (30) is longer than the length of the erection tool (lO), the buried object (B) can be fixed using the intersection of the reinforcing bars (30).

Further, the shape of the plate material may be appropriately changed to form a disk shape as shown in FIG. 6, and the avoidance portion (
The shape of i5) may be changed and implemented as appropriate without departing from the spirit of the present invention.

(Effects of the Invention) As described in detail above, the erection tool for a concrete buried object according to the present invention can be easily manufactured by punching out a board, etc., and can be used to install a buried object into a concrete wall. In the case of a wall that is built and buried under the support steel reinforcement, the concrete in front and behind the erection tool hardens through the through holes, so it is necessary to strongly connect the erection tool and the concrete wall together to prevent a decrease in the strength of the concrete wall. It has excellent effects.
