Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a fluid that accommodates a joint through which a fluid such as hot water, water, or gas passes, and that is attached to a wall hole with a flange and a holding piece sandwiching a wall. The present invention relates to a piping box, and more particularly to a fluid piping box suitable for piping work of fluids such as hot water, water, and gas in a building after installation on a wall.

(Prior art) In recent years, heating systems using hot water have become widespread, and along with this, pipes for passing fluid such as hot water from water heaters have been installed in the building, and outlets have been installed on the walls of each room. Plumbing work to connect to the plug of the hot water heater in the room is being actively carried out.

In such plumbing work, a method is usually employed in which piping is performed behind a wall, and a fitting that serves as an outlet and a fluid piping box that stores the fitting are fixed to a crosspiece or the like behind the wall before the wall is installed. .

However, since the plumbing contractor and the wall installation contractor are separate, it may be necessary to install the fluid piping box after the wall is installed due to work setup and the contractor's convenience.

In such a case, conventionally, as shown in FIG. 7, a separate flange member (41) is attached to the side wall of the fluid piping box (40), and the fluid piping box is inserted from the wall surface into the wall hole. The flange member 41 is brought into contact with the wall, and a screw is inserted into a screw mounting hole (42) provided in the flange member (41) to attach the fluid piping box (40) to the wall.

(Problems to be solved by the invention) However, in the case of using a conventional fluid piping box to which a collar member is attached, it is troublesome to attach the collar member to the fluid piping box, and in order to attach a screw. There is a problem in that the brim member largely protrudes on the wall surface and the appearance is poor.

In addition, if the fluid piping box is distorted when screwing it down, it is difficult to redo the work, and when the screw hole is initially installed, the fluid piping box becomes weakly attached. There was a problem.

The present invention has been made in view of such circumstances, and after the wall is installed, it can be easily attached to the wall hole by work from the wall surface, and the work of reattaching to the wall hole can be easily performed, and the wall surface can be easily attached. An object of the present invention is to provide a fluid piping box that can be mounted in a clean state.

(Means for Solving the Problems) That is, the box for fluid piping according to the present invention is
A box for fluid piping that houses a joint to which a fluid pipe through which a fluid such as water or gas passes is connected.A flange protruding outward from the side wall and a screw with its head facing the opening are screwed into the box. It has a sandwiching piece that can be pulled in and out from the side wall by rotating the screw and can slide back and forth, and the collar part is brought into contact with the outer wall surface of the peripheral edge of the wall hole, and the sandwiching piece projects from the side wall by rotating the screw. It is made to slide while it is made to slide to a collar part, and a wall is pinched | interposed with a collar part and a clamping piece, and it attaches to a wall hole.

(Operation) Therefore, in the fluid piping box according to the present invention, the fluid piping box is inserted into the wall hole, and the flange portion protruding outward from the side wall of the fluid piping box is formed on the outer wall surface of the wall hole periphery. After the abutment, the screw with its head facing into the opening for the fluid piping box is rotated to project the clamping piece from the side wall, and the screw is rotated to project the clamping piece from the side wall. It can be attached to the wall hole by sliding it toward the section and sandwiching the wall with the collar section and the sandwiching piece.

As shown in FIG. 1, on the opening side of the side wall (1a) of the fluid piping box (1), a collar portion (3) protruding outward from the peripheral edge of the opening (2) is formed. As shown in FIG. 4, the collar portion (3) may be anything that can come into contact with the wall surface around the wall hole (10) when the fluid piping box (1) is inserted into the wall hole (10). It may be formed on the entire periphery of the opening (2) or may be formed partially, and its shape is not limited. Further, the collar portion (3) may be provided integrally with the fluid piping box (1) or may be attached separately. The collar portion (3) may be provided with an attachment portion of the plate (8) that covers the opening (2) of the fluid piping box (1).

As shown in FIG. 2, in the side wall (1a) of the fluid piping box (1), a recess (4) is formed at a corner portion on the bottom wall side, and a screw (4) is formed in the recess (4). The holding piece (6) into which 7) is screwed is stored. Further, a notch (5) through which the holding piece (6) can pass from the recess (4) is formed toward the opening side of the side wall (1a) of the fluid piping box (1). The bottom wall (1b) and the opening (2) of the fluid piping box (1) located at both ends of the notch (5) are provided with insertion holes for the screw (7), and the screw (7) is opened ( The head (7a) is exposed inside 2) and is inserted into the insertion hole along the notch (5). In this embodiment, the sandwiching piece (6) and the screw (7) are provided at two locations on the diagonal line of the fluid piping box (1). It is not limited to this.
