Description

[Detailed Description of the Invention] The present invention relates to an end cover for conduit piping.

Conventionally, when piping a conduit inside a slab, in order to expose the tip of the conduit to the bottom surface of the slab, the vertical cross section is approximately 〓 shape as shown in Fig. 1, and the plane is approximately 〓 shape. An end cover for conduit piping is used, which is made by pressing a thin metal plate into an elongated horse-clamp shape.The method for using it is as shown in Figure 2. Fix the end cover 2 at its flange 3 using nails 4, etc., and insert the conduit 6 from the opening 5 at the rear end.
is inserted into the conduit piping end cover 2, and concrete is poured and hardened to form a concrete slab 7. After removing the panel 1, as shown in FIG. 3, the tip of the conduit conduit 6 is bent using a conduit bending machine (bender) 9 attached to the tip of the long bar 8, and then the end cover 2 for conduit piping is attached. It must be removed.

However, in the conventional end cover 2 for conduit piping described above, when inserting the conduit 6 into the end cover 2 for conduit piping, it is difficult to position the conduit sufficiently in the center, and furthermore, it is difficult to place the conduit 6 sufficiently in the center. is end cover 2 for conduit piping and panel 1
The conduit 6 cannot be held by the conduit clamping piece 10 at the tip of the conduit bending machine 9. Therefore, as shown in FIG. 4, the concrete slag is removed using a metal spatula 11 attached to the tip of the long rod 8, or the conduit 6 is moved to the center position, and the conduit 6 and the end cover for conduit piping are removed. 2, a gap must be formed in which the conduit clamping piece 10 can be inserted, and in order to remove the conduit piping end cover 2, the above-mentioned spatula 11 or the like must be used. This requires a great deal of effort and time, and since the removal of the panel 1 cannot be done at the same time, the floor surface must be cleaned repeatedly, which is inefficient.

In order to facilitate the removal of the end cover 2 for conduit piping, one end of the string 12 is fixed to the inner surface in advance as shown in FIG. An end cover for conduit piping that is easy to remove has been considered, but the hanging strings get in the way of work, and it is not reliable.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and the end cover for conduit piping has a vertical cross-section of approximately 0.5 mm and a plane of approximately elongated horse-clamp shape. When the conduit is installed in the end cover, a small plate is placed between the flanges near the top of the conduit, and a pair of protrusions or The present invention provides an end cover for conduit piping that is configured to have a concave portion so that it is easy to take out the conduit and remove it from the slab, and the conduit can be removed at the same time as the panel is removed.

The present invention will be explained in detail below based on embodiments shown in the drawings.

Figures 6 to 8 show an embodiment of the present invention, in which a thin plate made of metal such as iron is press-molded so that its vertical cross-section has a substantially square shape, and its plane surface has a substantially elongated horse-clamp shape. A small plate 15 made of a thin metal plate is stretched between the flange portions 14 at the tip of the formed end cover body 13 for conduit piping. This small plate 15 has a length as shown in FIG.
4, with both ends 15a and 1
5b is folded onto the back side of the flange 14, and is fixed to the conduit piping end cover main body 13 by punching a hole from above or below with a punch or the like. And the end cover body 13 for the electric conduit piping
A pair of convex portions 17a, 17 having an oval shape as a whole are located at positions from the center to the rear of both body portions 16a, 16b.
b is facing inward. Further, FIG. 9 shows another embodiment of the present invention, in which the side body parts 16a, 1
Concave portions 18a, 18b are formed opposite to the convex portions 17a, 17b formed on the conduit bending machine 9 in advance.
An insertion portion for the conduit clamping piece 10 is secured.

The method of using the end cover for conduit piping according to the present invention is to install it in the same manner as the conventional end cover for conduit piping. At this time, in the case of the present invention, since the small plate 15 is fixed near the tip, when the conduit tube 19 is inserted into the cover, the tip of the conduit tube 19 will come into contact with the small plate 15, so this can be used. By inserting the conduit until it touches the conduit, there will be no situation where a sufficient length cannot be obtained when pulling out the conduit.

In the embodiment shown in FIGS. 6 to 8, the pair of convex portions 17a and 17b formed on the side body portions 16a and 16b serve as guides, and the conduit 19
is located at the center of the end cover body 13 for conduit piping. Therefore, when the panel is removed, there is a sufficient distance between the conduit 6 and the end cover body 13 for conduit piping, and the conduit can be easily bent using a conduit bending machine. Furthermore, the end cover for conduit piping can be easily and reliably removed by hooking a square-shaped fitting (not shown) attached to the tip of a rod onto the small plate 15 and pulling it downward. Further, the embodiment shown in FIG. 9 may be used in the same manner as the above embodiment, but in this embodiment, recesses 18a and 18b for the wire bending machine are formed in advance. It is possible to obtain the same effects as in the previous embodiment without locating the conduit at the center of the end cover body 13 for conduit piping.

Since the present invention is constructed as described above, it is possible to easily bend the conduit after the panel is removed and to remove the end cover for the conduit piping itself, and it also has various effects such as being able to be supplied at low cost and in large quantities. It is something that you have.
