BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connection structure of wiring ducts, and more particularly, to a structure for connecting wiring ducts installed in ceilings or walls of buildings.

In general, if wires that supply electricity, cables or wires for transmitting or receiving data signals such as computers or printers, telephones or speakers, and various wiring devices are exposed to the outside, the wires may be twisted or tangled, which may not be good. In addition, interference with other objects may cause a safety problem for the wiring state.

In order to prevent such a problem, a large number of wires or cables, etc. are not exposed to the outside, the wiring state can be easily organized, and the wiring ducts are mainly used to protect the wires or cables.

Such a wiring duct is usually installed in a state embedded in a wall or exposed to a floor, wall, or ceiling. Wiring ducts are made of metal or synthetic resin, applied in the form of unit lengths or modules for wiring, and cut and used as necessary.

In addition, the wiring duct is used by combining a plurality of wiring ducts in consideration of the working environment and the use environment. In addition, wiring ducts are installed by connecting and combining a plurality of ducts in a straight line or branching from a straight line according to the installed environment. Therefore, when installing the wiring duct, such as simply using the designed work drawings or on-the-fly installation according to the conditions of the site, such as the installation and layout of the wiring duct irregularly exposed the disadvantages that impair the aesthetics and safety.

In addition, when the lighting reflector-integrated wiring ducts are connected in a straight line for indoor lighting and installed separately, they not only spoil the external appearance of the corners or the center of the ceiling, but also are not easy to install. There was a problem that can not be used.

On the other hand, the main body which is conventionally installed along a predetermined position such as a ceiling or a wall is standardized with a predetermined size and length, and in order to connect the branching body branched from the main body, the side of the main body is cut by the width of the branching body, The branch part connected with the main body of the cut part is processed, respectively. And after inserting or connecting a branch body to a main body, the part which connects a main body and a branch body is connected by welding, and a connection part is coated.

However, in the case of connecting the main body and the branch in this way, this connection method is preferable when the space to be installed is long or installed like a pole, but the structure that is installed on the wall and connected from the top is aesthetic The problem of eliminating the connection part is to make one piece from the top to the TEE branch point in the upper part, and the transportation vehicle is used to transport the long parts with different ceiling height depending on the building or room. There was a problem uncomfortable.

Moreover, in the case of the T-shaped branching in the T-shape, the branching gas branching from the main body is usually smaller than the size of the cross-sectional area of the main body. That is, the main body is provided with a space that can accommodate a large number of wires, the branching body branched from the main body is provided a smaller space than the main body by receiving a smaller number of wires than the main body. Therefore, the process of cutting, processing, welding and painting the main body for connection and coupling of the branching body and the main body branched from the main body has a problem that the supply and demand of materials is not easy.

The present invention has been made in order to solve the above problems, in the case of connecting and connecting the branch having different heights and widths from the main body, the side wall of the main body is cut, the branch is connected to the cut portion to integrate and integrated An object of the present invention is to provide a connection structure of a duct for wiring, which simplifies the connection process by selectively coating the connection site and maintains a predetermined bond strength.

In order to achieve the object according to the invention, in the wiring duct,

A cutout portion, such as the height and width of the branch, is cut and formed on the side wall of the main body, and one end of the branch is inserted and connected to the cutout. A plurality of connecting members are provided inside the lower wall of the main body and the lower wall of the branch. It is characterized by providing a connection structure of a wiring duct in which the main body and the branch body are fixed by fixing with fixing means.

Hereinafter, with reference to the accompanying drawings will be described in detail with respect to the connection structure of the wiring duct of the present invention.

First, the present invention is a structure for connecting and coupling a main body of a wiring duct and a branch branched from the main body, and is preferably applied when the cross-sectional area of the main body and the branch body is different. Furthermore, since the wires wired into the main body branch through the branching body, the width and height of the main body are larger than the width and height of the branching body. Therefore, the branch branched from the main body is preferably a duct of a relatively small capacity, but depending on the work configuration, the specifications of the main body and the branch may be relatively formed regardless of the wire capacity.

The main body 10 is a form in which the upper end is opened or the cover is coupled, and a plurality of reinforcement protrusions or grooves or reinforcement jaws are formed at the inner side in a continuous shape in a ?? shape. The main body 10 is formed with a predetermined cutout 16 for connection with the branch body 20 from the side surface. The cutout 16 is preferably cut according to the width and height of the branch 20 to be cut or connected to a predetermined size in advance.

The incision 16 is incised by the width and height of the branch body 20 connected to the main body 10. The incision 16 is cut off by the height of the branch body 20 from the bottom surface of the side wall 12 of the main body 10 to the top. The main body 10 is cut in a predetermined width from the outside to the inside of the bottom wall 13. That is, a reinforcing jaw 17 is formed in the portion where the side wall 12 and the bottom wall 13 of the main body 10 are bent at right angles to achieve the rigidity of the main body 10. It is preferable to cut to the jaw 17. Therefore, the cutout 16 formed on the side wall 12 of the main body 10 is cut to the position where the bottom wall 13 is formed with the reinforcing jaw 17 from the outside, and the top portion of the sidewall 12 is not cut off. It will remain intact.

Although the cutout portion 16 may be cut inwardly beyond the reinforcing jaw 17, a range capable of maintaining connection strength with the branch body 20 while minimizing interference of wires wired inside the main body 10. It is good to incision up to. A plurality of grooves 14 and 15 are formed inside the main body 10 so that the connecting member 30 may be coupled using the fixing means 32a and 32b.

On the other hand, the branch body 20 is a form in which the upper end is open or the cover is coupled, a plurality of reinforcement projections or grooves or reinforcement jaw and the like is formed in a continuous shape left and right in the ?? shape. It is preferable that the branch body 20 is the same form as the main body 10, but may be another form. However, the branch body 20 may have a smaller width and height than the main body 10. One end of the branch body 20 is preferably in the form of a finish process so that the insertion portion 26 inserted into the cutout 16 formed in the main body 10 can be firmly and easily connected.

The connecting member 30 is coupled to the inner surface of the lower wall 23 of the main body 10 and the branch 20 in a rectangular plate shape, and a plurality of coupling members 30 are coupled to the main body 10 and the branch 20. Through-holes 31a-31d are formed. The connecting member 30 is disposed in a direction perpendicular to the main body 10 in a state in which the branch body 20 is connected through the cutout 16 of the main body 10, and the branch body 20 is disposed in the longitudinal direction. do.

Then, the connecting member 30 is placed in the state in which the main body 10 and the branch body 20 are connected, and the groove 14 and the minute portion of the main body 10 are divided through the through holes 31a-31d of the connecting member 30. Fixing means 32a to 32d are fixed to the recesses 24 and 25 of the base 20, respectively. The fixing means 32a-32d are preferably threaded bolts.

According to the present invention made as described above, a process of connecting and fixing and coupling the branch body to the main body is as follows with reference to the sectional view of FIG. 4 and the perspective view of FIG. 5.

First, the position at which the branch body 20 branches from the main body 10 when the main body is installed on the inner wall, the outer wall of the building, the wall, or the ceiling may be determined depending on the design or the situation at the time of installation.

The cutout 16 is formed at a position where the branch body 20 branches from the main body 10. The cutout 16 cuts from the bottom wall 13 toward the top of the sidewall 12. The bottom wall 13 is cut to the reinforcing jaw 17 and the top end of the side wall 12 is not cut toward the top. It is preferable that the branch body 20 is smaller in height than the main body 10. In other words, the insertion part 26 of the branch body 20 is inserted into the side wall 12 of the main body 10 so as to be cut. In the present invention, the cutout 16 is formed on the right sidewall 12 of the main body 10. However, when the branch body 20 branches from the left side, the cutout may be formed on the left sidewall 11. Although the cutout 16 may be cut off at the installation site, the cutout 16 may be formed in the main body in advance by design.

After the incision 16 is formed in the main body 10 as described above, the main body 10 is fixedly installed on the wall, and the insertion part 26 of one end of the corresponding branch 20 is inserted into the incision 16. To connect. And the branch body 20 is also installed after fixing to a wall.
