Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of the constituent members of the piping unit. The piping unit includes a central frame 1 and a pair of side frames 4, 4 erected on both sides of the central frame 1 at intervals. As shown in FIG. 2, a front plate 6 is fixed to the front side of the center frame 1. Further, the pair of side frames 4 are formed in the same shape that can be shared by the left and right, and are erected to face each other.
A plurality of vertically long holes 4a, 4a, 4a are formed on the rear surface.

As shown in the plan view of FIG. 3, such a central frame 1 can be brought into contact with a wall surface W of a building and fixed to the wall surface W by mounting bolts 2. On the other hand, the interior wall surfaces Wa and W after the interior of the site is completed
a on each side frame 4
Can be easily installed corresponding to the frontage of the site. A urinal 9 is installed on the front surface of the front plate 6. Inside the central frame 1, horizontal drawing pipes 10, 10, a drain trap, a flush valve, a deodorizer, etc. Assemble the functional parts of
It can be brought to the site.

As shown in the perspective view from the front side in FIG. 4 and the perspective view from the back side in FIG. 5, the center frame is formed in a box frame shape with front and rear and side surfaces opened by a metal plate. A plurality of oblong holes 1a, 1a, 1a are formed in the front surface, and an opening 1c through which a hand can be inserted from the front side is formed in the center of the front surface. After fixing the central frame 1 at a predetermined position via the central frame 2 and 2, a hand is inserted into the opening 1 c of the central frame 1, and the hand screw 3 is inserted into each elongated hole 1 of the central frame 1.
a, and the hand screw 3 is fastened to the embedding nut 8 embedded and fixed to the back side of the side decorative plate 7 to fix the side decorative plate 7. If the embedding nut 8 is also fixed, the hand screw 3 is inserted into the oblong nut 1 from the opening 1c into the oblong hole 1a, and the hand screw 3 is inserted into the oblong hole 1a from the back side. The front plate 6 can be fixed well by tightening. FIG. 6 is a half cross-sectional perspective configuration view of the central frame 1 showing a state in which a hand is inserted from the opening 1c side and the hand screw 3 is inserted into the horizontally elongated hole 1a from the back side.

As described above, the fixing work of the front plate 6 and the side decorative plate 7 can be performed favorably by inserting a hand from the front side, and since it is the hand screw 3, it is not necessary to use a tool as in the prior art. The work can be satisfactorily tightened by hand, and the work of using a tool in the narrow central frame 1 as in the related art can be omitted, thereby facilitating the work of assembling the piping unit. Also, the vertically long holes 4a, 4a,
The hand screw 3 is also inserted through 4a, and the hand screw 3 is fastened to the embedding nut 8, whereby the side decorative plate 7 can be firmly fixed. On the other hand, when the front plate 6 is detached, the front plate 6 is inspected, the opening 6a for construction and 1c of the central frame 1 are removed.
By inserting a hand into the inside from the front side, the hand screw 3 is loosened, the side decorative plate 7 and the front plate 6 can be easily removed, and maintenance work and the like are also easy.

After the central frame 1 and the side frames 4, 4 are installed in accordance with the site, the front surfaces of the pair of side frames 4, 4 are covered with the pair of side decorative plates 7, 7. As shown in FIGS. 2 and 3, the edge of the side decorative panel 7 on the central frame 1 side is swallowed on the back side of the front panel 6, and the side decorative panel 7 is appropriately moved in the horizontal direction through the horizontally long hole 1 a. And the side decorative boards 7, 7 can be easily and clearly attached in accordance with the frontage size of the site.

FIG. 7 is a perspective view of a constituent member of the plumbing unit for a toilet bowl. In FIG. 7, an opening 1c for inserting a hand from the front side of the central frame 1 is shown.
A plurality of oblong holes 1a, 1a, 1a are formed around the opening 1c on the front side, and side holes of the central frame 1 are spaced apart on both sides. The frames 4 and 4 can be erected, and the front side of the central frame 1 has an opening 1c as described above.
The hand screw 3 is inserted into each of the horizontally long holes 1a by inserting a hand from the side, and tightened to the embedded nut 8 embedded and fixed on the back surface of the front plate 6 so that the front plate 6 can be fixed well. And a side decorative board 7
Similarly, b and 7b are configured such that the hand screw 3 can be tightened and fixed to the embedding nut 8 buried on the back side.

In this embodiment, each side decorative plate 7b, 7
The side decorative plates 7, 7 are attached to the upper part of b, respectively, and the upper surfaces of the side decorative plates 7, 7 are formed with bendable upper surface bent pieces 7c, 7c. The upper surfaces of the side frame 4 and the center frame 1 can be covered well by 7c, 7c.
The counter 22 is placed between the upper bent pieces 7c, 7c from above so that the gap between the side decorative plates 7, 7 is concealed by the counter 22, and the front hanging portion 22a of the counter 22 is also provided. Are superimposed on the front surfaces of the side decorative plates 7, 7, so that good design is obtained.

Also in this embodiment, using the opening 6a of the front plate 6 and the opening 1c of the center frame 1, a hand is inserted into the center frame 1 from the front side, and the hand screw 3 is tightened from the back side. Front plate 6 and side decorative plates 7, 7, 7
The fixing work of b and 7b can be performed, and the assembling work on site can be easily performed. In addition, the hand screw 3 can be loosened and easily removed at the time of maintenance.
