Description

Cable tray integrated expansion tray {Cable tray with expansion or reduction connection department}

The present invention relates to an integrated cable tray integrated connection, and more particularly, to connect the adjacent cable tray body without interconnecting members to fasten and securely fasten to reduce the manufacturing cost and earthquake, etc. Due to the cable tray body is connected to the longitudinal or transverse direction to the torsion, the shock is buffered, it is also possible to cope with temperature changes and the elasticity is possible to adjust the angle of the cable connection integrated cable tray.

In general, large and small diameter cables are installed along ceilings, floors, or walls for power supply or fluid supply in factories, ships, and offshore structures.In recent years, the quality of ultra-precision products such as semiconductors, LCDs, and photovoltaics In order to avoid inconvenience to aesthetics and passers-by, the cable is installed and fixed quickly and neatly in a neat state by using a cable tray.

In addition, cable trays can be classified into ladder type, bottom sealed type and perforated type according to the shape of the body, and according to the installation type, straight type, elbow type, tee type, cross type, straight reducer, right reducer, left reducer It can be classified as a dusher.

As described above, the cable tray is commonly manufactured to have a predetermined length, and then the cable tray is mutually coupled with other types of members.

1 is a view for explaining a coupling state with a connection member and a fixing member of the cable tray according to the prior art.

1 shows a ladder type straight cable tray.

Referring to FIG. 1, a plurality of hangers for connecting and supporting a pair of side frames 1a having a plurality of through-holes 1a-1 formed at both ends and spaced apart at regular intervals to the left and right sides of the cable trays. Cable tray body (1b) consisting of (1b), and fastening hole (2a) corresponding to the through hole (1a-1) of the side frame (1a) in order to continuously arrange the cable tray body (1) in the longitudinal direction The connecting member 2 is formed to interconnect the adjacent side frame (1a), and the through hole (1a-1) of the cable tray 1 and the fastening hole (2a) of the connecting member (2) It consists of a fixing member (3) to be fixed.
