The present invention relates to a vertical movement cover coupling outlet box, and more particularly, a vertical movement cover in which elastic foaming resin packing and an uneven ring are combined in a central space on both sides of which an inner wall and an outer wall are coupled to a vertical movement cover. By combining the elastic repulsive force of the uneven ring and the elastic foam foaming resin packing in the space, the vertical movable cover can move vertically vertically when applying physical force, and the vertical movable cover combining outlet to completely block the penetration of concrete water into the box. It's about the box.

In general, the outlet box embedded in the concrete wall has a variety of forms in which the cover is fixed to the box body or the ring cover is vertically moved by a compression spring.

However, when the outlet box is combined, the cover surface and the moving cover surface are in close contact with each other, but when the concrete is placed, both sides of the moving cover are deformed by the high pressure of the concrete, so that there is a gap with the cover surface. If the inside of the box is not only difficult to clean, but sometimes the wall breaks and the box needs to be replaced at the construction site.

The purpose of the present invention is to automatically adjust when the outlet box constructed on the vertical reinforcing bars for the wall when the outlet box is installed in the concrete wall when the clearance distance between the reinforcing bar and the formwork to be in close contact with the form surface It is to provide a vertical moving cover combined outlet box that prevents the both sides of the box from internally inflating with high pressure during concrete pouring and completely blocks the concrete mixture from penetrating into the box.

According to the present invention, a vertical moving cover 20 and an uneven ring provided with a box body 1 having a hub 2 to which a telecommunication cable line can be connected and branched, and an insert boss 22 for mounting an electric appliance. Outer box 30 is coupled to the outer space 10 is formed between the outer wall 10 and the inner wall 11 on the upper surface of the box body (1) is formed in the elastic foam resin packing in the inner space 12 40 and the vertical moving cover 20 is coupled to provide a vertical moving cover combined outlet box, characterized in that to block concrete water and move vertically and vertically with elastic force.
BEST MODE Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings.
Figure 1 shows a vertical moving cover coupling outlet box (A) according to the present invention, as shown in Figure 4, the box body (1) is injection molded from the mold with a synthetic resin, the telecommunication cable on the outer side wall A hub (2) joining the piping material (CD pipe) is formed so that the wire can be wired, and a knockout (3) for installing a connector is formed when the pipe water is added. In addition to the knockout (3) left and right vertically when the box is connected to the box and the spacer spacer (4 not shown here) for coupling the spacer to maintain the gap is formed and the hub (2) ) When constructing the box on the left, right, and right sides, the upper rebar hook 5 and the lower rebar hook 6 attached to the box fixed to the rebar are formed facing each other. In addition, the upper plane circumference of the outer wall 10 which is in close contact with the surface of the elastic concave-convex ring 30 having the concave-convex portion 31 (to be described later) and the vertical moving cover 20 (to be described later) to the inside at high pressure during concrete placement Between the inner wall (11) to prevent the gradation, the concrete foam blocking resin packing (40 to be described later) and the vertical movement cover 20 is coupled to the groove 12 with a space and a distance to move vertically vertically And a distance space 13 through which the separation preventing locking jaw 23 of the vertical movement cover 20 can vertically move up and down on the left and right side walls of the outer wall 10 and vertically above the space 13. The movable cover 20 is formed with a locking jaw 14 to prevent the elastic body from leaving the box body 1 by the repulsive force, and the upper flat center is formed as a space 17 into which the electric wire and the electric appliance are inserted. .
2 (A) (B) vertical movement cover 20 is a synthetic resin injection molding from a mold (not shown here), through the inside and coupled to the outlet switch (not shown here) to the left and right side walls A boss 22 having a built-in insert is formed, and the lower half body 25 is formed to have a length that the concave-convex ring 30 can be coupled (to be described later), and the departure prevention jaw 21 of the concave-convex ring 30 is formed at the center. Protruding in a ring shape and the box body (1) and the resilience of the locking jaw 14 and the coupling concave-convex ring 30 and the elastic foamed resin packing 40 formed on the left and right walls of the box body (1) at the bottom Hanging jaw 23 to prevent separation is formed is completed.
And (A) the concave-convex ring 30 of Figure 3 is a synthetic resin is completed by forming the concave-convex portion 31 is elastic in the brew mold (not shown here) and the vertical movement cover 20 body 25 ) The upper part is fitted to the outside of the uneven ring separation prevention jaw 21, the lower part is in close contact with the upper end of the outer wall 10 of the box body (1) to help vertical movement cover 20 vertical movement and to the body of the concrete (25) when concrete Close contact prevents the concrete mixture from penetrating into the box.
In addition, (B) the elastic foamed resin packing 40 of Figure 3 is produced by blowing air into the synthetic resin and cut to suit the barking standards, the box body (1) between the upper outer wall 10 and the inner wall (11) Push in the space groove 12 is in close contact with the bottom of the insertion groove 12 to prevent the concrete mixture from penetrating into the box and also serves to push up the vertical moving cover 20 with elastic force.
The vertical moving cover combined outlet box can be applied to various types of wall switch box, outlet box and communication box.

As described above, according to the present invention, the vertical moving cover coupling outlet box A embedded in the concrete wall has a recess 12 into which the elastic foamed resin barking 40 can be inserted into the upper surface of the box body 1. When pouring concrete, the concrete mixture does not penetrate into the box and automatically adjusts the clearance distance between reinforcing bars and formwork, so that the box surface and formwork are in close contact with each other. Because of the clean, labor costs such as box cleaning is greatly reduced.
