Description

[Detailed explanation of the idea] The present invention relates to cables used in coffered ceilings.

Most of the conventional cables were formed in one piece, and it was common to install the cables by arranging them vertically and horizontally on the ceiling.

However, with the recent trend towards system ceilings, there was a need for a connection line that was easy to install.

In order to meet this demand, a connecting line was devised that connects two divided pieces along the longitudinal direction so as to face each other, but this has the disadvantage that if the contact surfaces of the divided pieces are transparent, a step is likely to occur. Ta.

The present invention was developed in view of the above-mentioned circumstances, and its purpose is to provide a reliable connection line for construction that does not create a level difference on the abutting surfaces of the divided pieces.

Hereinafter, an embodiment of the present invention will be explained based on FIGS. 1 and 2.

B is a rectangular body 1 made of wood, synthetic resin, etc.
A chamfering process 3 is applied to the lower end of the lower side 2, and a see-through groove 4 is provided in the center of the lower side 2, and a convexity is formed along the longitudinal direction of the contact surface 7 above the center in the vertical direction. A groove 5 and a groove 6 are provided, and a groove 8 and a groove 9 are provided so as to correspond to each other along the longitudinal direction of the lower contact surface 7 and can be inserted freely and have unevenness 10 on the periphery. Divided piece At=
This is a connecting line that warns from A11l.

Then, a ceiling plate is placed and fixed on top of this connecting line B.

(Not shown) Note that the grooves 8 and the protrusions 9 having the unevenness 10 on the periphery may be arranged in a straight line on the contact surface 7 or may be arranged in vertical positions.

Therefore, the connecting line B is connected to the divided piece A1. Since the concave grooves 8 and the protrusions 9 of A2 are positioned by the unevenness 10 on the periphery and can be inserted freely, if the abutting surfaces 7 of the divided pieces A□ and A2 are transparent, there will be no step and they will become a single rigid body, preventing bending failure. The strength also increases.

As described above, the present invention is constructed by providing positioning by providing protrusions and grooves that can be fitted and inserted in correspondence with the abutment surfaces of each divided piece and have unevenness on the periphery, so that there is no difference in level between the openings and the gaps. It is a reliable construction that will not cause any damage.
