Description

[Detailed explanation of the idea] This invention relates to the piping structure of electrical conduits within a wall.

When piping a conduit inside a wall such as a partition panel of a building, conventionally, as shown in Fig. 3, a true wall switch box a is placed inside the wall and fixed to the crosspieces b, and then connected. Conduit C was connected to part a'.

Since the use of a switch box increases the cost accordingly, it is desired to install conduit pipes without using a switch box.

However, if the switch box was omitted, there would be no means to fix the conduit to the wall, and even if the conduit was tried to be fixed to the wall with mounting brackets, it was virtually impossible to attach the bracket to the wall because the panels and other walls were thin. .

This invention was made in view of the above points, and its gist is that the flange part of the flanged short pipe is locked to the crosspiece of the wall,
The present invention resides in a piping structure of an electric conduit inside a wall body, in which an electric conduit is connected to the flanged short pipe and is piped inside the wall body.

Next, this invention will be explained with reference to embodiments shown in the drawings.

1 is a wall such as a partition panel, and this wall 1 is a first
The figure shows the front wall removed.

11 is a horizontal bar, and 12 is a vertical bar.

Reference numeral 2 denotes a conduit, which is disposed inside the wall 1 with a wire draw-out section 13 remaining, and this conduit tube 2' fills the space 13 of the wire draw-out section.
It is inserted into the through hole 111 of the horizontal beam 11 that partitions the wall, and is connected to the flanged short pipe 3 which is inserted and locked from the opposite direction to this insertion, so that it is fixed and piped inside the wall body 1. .

The flanges 31 of the flanged short pipes 3 are fixed to the horizontal beams 11 as described above, and must fit inside the wall 1. Depending on the thickness of the wall 1, the two parts of the flanges 13 are parallel to each other. It has a notch in it.

Of course, if the diameter of the flange 31 is smaller than the thickness of the wall 1, there is no need to cut it out, but normally the thickness of the conduit is smaller than the thickness of the wall 1.
Since the thickness is close to , it is preferable to make two parallel notches on the flange as in the embodiment.

Further, the area around the center hole of the collar 31 is rounded to protect the electric wire.

It is preferable that the flanged short pipe 3 and the electric conduit 2 be connected with adhesive because the installation work is easy.

Further, a cover body or the like is attached to the wire draw-out portion 13 after wiring without attaching a front wall surface.

As described above, in this invention, the conduit is connected to a short flanged tube whose flanges are fixed to the crosspiece in a relatively thin wall such as a partition panel. It is possible to provide an inexpensive intra-wall internal wire tube connection structure that is fixed to the crosspiece due to the mutual relationship with the short tube and eliminates the need for a switch box or the like.
