Description

  The present invention is for concrete burying in which a protective pipe into which a water pipe such as a water supply pipe is inserted is embedded inside a concrete wall, floor, ceiling, etc. of a house or an apartment, and a drain pipe such as a water tap is arranged outside. The present invention relates to a pipe placement tool and a concrete buried pipe construction method using the same.

Conventionally, as a method of embedding pipes such as water supply pipes inside reinforced concrete walls and floors in houses and condominiums, etc., a protective pipe made of synthetic resin or the like is embedded in the concrete of the frame in advance. A so-called sheath pipe construction method is used in which a water supply pipe made of synthetic resin or the like is inserted to embed a pipe.
In recent years, there has been an increase in the construction of houses and condominiums with water faucets, pet sinks, outdoor faucets for washing machines and water heaters on the outer walls made of reinforced concrete, and they have been inserted into protective pipes embedded in concrete There is a need for a technique for connecting a water pipe and a faucet provided on a concrete outer wall.
As such a technique, for example, (Patent Document 1) discloses “a faucet box for connecting a water supply pipe inserted through a protective pipe embedded in a concrete wall and a faucet provided on the outer surface of the concrete wall”. Yes.
JP 2002-294774 A

However, the above conventional techniques have the following problems.
(1) The technology disclosed in (Patent Document 1) is a sheath pipe (protective pipe) embedded in concrete as described in the third column of the publication, left column, line 46 to right column, line 7. The faucet box is connected by a sheath pipe connecting portion, and the faucet box is housed in a cavity formed in the concrete wall and fixed to the concrete surface with screws or the like. Therefore, it is necessary to form a cavity in the outer surface of the concrete frame to embed the sheath pipe or store the faucet box, and to bury the sheath pipe on the inner surface of the formwork used when placing concrete. In addition, since a mold for forming a cavity for storing a faucet box must be separately provided, there is a problem that the workability is lacking.
(2) In addition, after concrete is cast to form a concrete wall, a cavity for burying a sheath or storing a faucet box is also formed. It must be removed using a tool such as a drill to form a cavity, which requires work man-hours and imposes a heavy burden on the operator. It had a problem that it was extremely lacking in properties.
(3) After housing and fixing the sheath pipe and faucet box in these cavities, it is necessary to fill the surface of the sheath pipe and faucet box with repair mortar etc. so as to be flush with the surface of the concrete frame. However, since the cavity for housing the sheath pipe and the faucet box is large, a large amount of mortar is required and many man-hours for filling the mortar are required, resulting in lack of workability.
(4) It is possible to place a sheath pipe on a reinforcing steel rod for concrete reinforcement before placing the concrete, and then place the sheath in the concrete frame by placing the concrete. After the installed concrete is hardened and the formwork is removed, it is necessary to connect the sheath tube and the faucet box and fix the faucet box in the housing. These operations have a problem that the work space is limited due to the hardening of the concrete frame, which is complicated and lacks workability.
(5) Since the periphery of the faucet box to which the protective pipe into which the water supply pipe has been inserted is completely covered with concrete in the housing, when replacing the water supply pipe for maintenance, The concrete surrounding the stopper box had to be removed and the faucet box had to be taken out of the housing, which had the problem of lack of maintainability.

The present invention solves the above-described conventional problems, and provides a method for constructing a concrete burying pipe that can easily perform a work of burying a water pipe such as a water supply pipe in a concrete body and has excellent workability. Objective.
In addition, the present invention is such that after the reinforcing bars for reinforcing concrete are arranged, the operation of fixing the water discharge box and the water transfer box in which the protective pipe is connected to the reinforcing bars is performed, and the water discharge box and the water transfer box are placed inside the concrete frame. Protective pipes, flooding boxes and water transfer boxes can be embedded in the concrete frame without the need to form storage cavities. An object of the present invention is to provide a concrete laying pipe placement tool used in a concrete burying pipe construction method that can be stably buried and is excellent in the stability of pipe construction quality and also in maintainability.

In order to solve the above-described conventional problems, a concrete laying pipe arrangement tool and a concrete burying pipe construction method using the same according to the present invention have the following configurations.
The construction method of the concrete underground piping according to claim 1 of the present invention is applied to the reinforcing steel reinforcing bars for reinforcing concrete.
(A) a flooding box body having an opening on the front surface;
A protective tube connection hole to which one end of a protective tube is formed, which is formed on the bottom surface or side wall of the water discharge box main body and into which the water flow tube is inserted;
The bottom surface portion of the water discharge box main body and the side wall portion or the bottom surface portion, or a protrusion of a ridge protruding outside the side wall portion, and / or the protrusion or the bottom surface portion of the water discharge box main body, or An insertion hole formed in any one or more of the side walls;
A water discharge box having a support member mounted on the protrusion, and
(B) a water guide box body having an opening on the front surface;
A protective tube connection hole formed on the bottom surface or side wall of the water guide box body and connected to the other end of the protective tube;
The bottom surface portion of the water guide box body and the side wall portion or the bottom surface portion, or a protrusion of a protrusion protruding outside the side wall portion, and / or the bottom surface portion of the protrusion or the water guide box main body, or An insertion hole formed in any one or more of the side walls;
A water guide box having a support member mounted on the protrusion, and guiding the water pipe to the water discharge box,
A box installation step of disposing and fixing the water discharge box and the water conveyance box by installing a support member on the protrusion of the water discharge box and the water conveyance box;
Protective pipe connection for connecting both ends of the protective pipe to the protective pipe connecting hole of the water discharge box and the water guide box and closing the opening by disposing a closing member at the opening of the water outlet box and the water guide box. Process,
Forming an opening for removing the closing member disposed in the opening of the water discharge box and the water guide box after curing and curing of the concrete placed in a formwork disposed at a predetermined interval from the reinforcing bar Process,
After the water pipe is disposed in the water guide box main body, the protective tube, and the water discharge box main body from the opening opened in the opening forming step, the opening is made to the water discharge box main body and / or the water discharge box main body. Closed by a lid member having a lid body detachably disposed in the opening of the water guide box body, and a lid opening formed in a predetermined portion of the lid body and through which the water pipe or the water outlet pipe is inserted. And a water pipe arrangement step .
With this configuration, the following effects can be obtained.
(1) Since the protective tube has a protective tube connecting hole portion to which one end portion of the protective tube is connected, a protruding portion and / or an insertion hole portion of the protrusion, and a support member mounted on the protruding portion, the protective tube Can be connected to the reinforcing bars for concrete reinforcement using the protrusions of the ridges, the insertion holes, and the support members installed on the protrusions. After being installed, a protective tube is connected to the reinforcing bar, and it is stored in the concrete frame simply by fixing the flooding box provided with the protrusion of the ridge and the support member mounted on the protrusion. Therefore, it is possible to embed a protective tube and a water discharge box in a concrete frame without requiring a work for forming a hollow for use, and the workability is remarkably excellent.
(2) Before concrete is placed, a concrete outlet can be connected to a protection pipe by placing and fixing a water discharge box and a water guide box with supporting members mounted on the protrusions.
