Is suppressed in the axial rotation direction, and a stable storage state can be obtained. Therefore, the handleability when not in use is excellent, and packing, transportation, storage and the like can be performed efficiently. Further, the cutting operation at the time of using the cutting can be easily performed.

This duct is installed on the wall as follows. First, screw holes are provided at required positions on the wall surface in order to fix the mounting base 1 to the wall surface. At this time, the mounting base 1 is fixed by using two mounting holes 5 near the one end and the mounting hole 5 near the other end, or one at the approximate center, and using the three mounting holes 5. It is common to provide a screw hole so that the screw hole is formed. Next, the mounting base 1
The mounting base 1 is fixed by screwing a screw member, for example, a wood screw into the screw hole in a state where the mounting hole 5 and the screw hole on the wall surface overlap with each other. When tapping screws are used, there is no need to provide a screw hole in the wall in advance, and the mounting base 1 is fixed by supporting the mounting base 1 at a required position and screwing the tapping screws into the wall.

Here, when the mounting base 1 is fixed to the wall surface in a direction substantially horizontal to the ground, for example, at a gradient of 1/50 or more, there is a case where it is desired to correct the gradient of the mounting base 1 once fixed. . In this case, according to this pipe accommodation duct, after the wood screw or the tapping screw is loosened, the slope is corrected by displacing the mounting base 1 in the width direction of the mounting hole 5 without moving the position of the screw member with respect to the wall surface. It can be done easily. Therefore, once the screws are removed and the mounting base 1 is removed from the wall surface, a new screw hole is provided in the wall surface, or the mounting base 1 is shifted to a required position and the tapping screw is re-threaded in a different place from before. It is not necessary to take a lot of trouble, and it is easy to solve problems such as difficulty in flowing water in the drain pipe due to excessive or insufficient gradient or forgetting to take it, impairing aesthetic appearance, and inconvenience in connection with other members Can be prevented.

After the mounting base 1 is mounted on the wall, the pipe is housed and piped along the mounting base 1, and the concealing cover 12 is engaged with the mounting base 1. The engagement of the concealing cover 12 with the mounting base 1 is performed as follows. First,
One of the engaging pieces 17 of the concealing cover 12 is engaged with one of the engaging grooves 10 of the mounting base 1, and in this state, the other engaging piece 17 of the concealing cover 12 is engaged with the other locking portion 9 of the mounting base 1. Contact. Then, when the concealing cover 12 is lightly pressed toward the mounting base 1 while lightly pressing the other side wall of the mounting base 1 inward, the other engaging piece 17 of the concealing cover 12 is moved to the other locking portion of the mounting base 1. 9 Slide outward on the upper surface and securely engage with the other engaging groove 10 of the mounting base 1. Conversely, when the concealing cover 12 is to be removed, one of the side walls of the mounting base 1 is gently pressed inward while the one engaging piece 17 of the concealing cover 12 is gently pressed in a direction away from the mounting base 1. Thereby, the engaging piece 17 of the concealing cover 12 can be removed from the engaging groove 10 of the mounting base 1.

Here, since the locking portion 9 of the mounting base 1 is provided in a hinge shape, one engaging piece 17 of the concealing cover 12 is engaged with one engaging groove 10 of the mounting base 1. In this state, the engaging operation can be performed by rotating the concealing cover 12 about the locking portion 9. Also, the locking part 9
Guides the engaging piece 17 of the concealing cover 12 into engagement with the engaging groove 10 of the mounting base 1 when the concealing cover 12 is engaged with the mounting base 1, and conversely, the concealing cover 12 is When removing from the mounting base 1, the engaging piece 17 of the concealing cover 12
Is guided so as to be disengaged from the engagement groove 10. Accordingly, the work of engaging and disengaging the mounting base 1 and the concealing cover 12 can be performed easily and promptly without applying a strong force.

In addition, when the concealing cover 12 and the mounting base 1 are engaged with each other, an excessive load is applied from the concealing cover 12 to the mounting base 1 or a soccer ball collides with the concealing cover 12 in the engaged state. Even if there is an external impact, the engaging piece 17 of the concealing cover 12 and the stepped portion 8 of the mounting base 1, the reinforcing locking portion 18 of the concealing cover 12 and the locking portion 9 of the mounting base 1 are fixed to the concealing cover 12. Abuts substantially perpendicular to the direction in which force is applied from the side to the mounting base 1 side, and the reinforcing locking portion 18 supports the force applied from the concealing cover 12 side to the mounting base 1 side. 1 does not easily come off, and a stable and firm engagement state can be ensured.

Further, in this piping housing duct,
Since the engaging piece 17 of the concealing cover 12 and the reinforcing locking portion 18 sandwich the locking portion 9 of the mounting base 1, the concealing cover 12 and the mounting base 1 are hardly displaced in the longitudinal direction. Has become. Then, in a state where the two are engaged, the shaft portion of the tapping screw A is screwed into the locking hole 11 of the concealing cover 12 and inserted therein, so that both the concealing cover 12 and the mounting base 1 have the tapping screw A. Since both are locked to the head Aa, it is more difficult for the two to be misaligned in the longitudinal direction. Therefore,
A series of installation work including the connection member can be performed satisfactorily without any inconvenience due to displacement, and the workability is improved.

The mounting hole of the mounting base is, for example, as shown in FIG.
As shown in the figure, the mounting holes 5 long in the width direction and the mounting holes 5a long in the longitudinal direction may be provided alternately. In short, at least one at each end of the mounting base is long in the width direction. An attachment hole may be provided. Further, the locking holes may be provided in the engaging walls of the concealing cover instead of the opposing side walls of the mounting base. Further, the locking hole may be one in which a female screw is engraved on the inner surface so that a wood screw can be inserted, for example.

[0024]

According to the pipe housing duct of the present invention, the shaft of the screw member is inserted into the engaging hole provided in the opposing side wall of the mounting base or the engaging wall of the concealing cover in the longitudinal direction of the opposing side wall or the engaging wall. <br/> Since the head is engaged with both the mounting base and the concealing cover while being inserted, the two are less likely to be displaced in the longitudinal direction. Therefore, the arrangement work can be performed favorably, and the workability is improved.
