Description

Earthquake Resistant Type Cable Tray System

The present invention relates to a seismic cable tray system, and more particularly, to a seismic cable tray system that facilitates seating of a cable in a hanger of a cable tray while enhancing the seismic resistance.

Generally, big and small diameter cables are arranged along the ceiling and floor or wall for supply of power supply or fluid to the factory, ship and offshore structure, and the cable arranged in this way gives inconvenience to aesthetics and passers In order to avoid this, the cable tray is used to support and fix it.

 A conventional cable tray for supporting and fixing various cables as described above includes a pair of side frames each having a largely constant length and positioned on each of the left and right sides and a hanger (rod-shaped, plate-shaped) .

In addition, the cable tray uses a support member for fixing the cable tray to a ceiling or a wall surface. The support member is composed of a pair of computer bolts vertically arranged with the anchor bolts embedded in the ceiling of the building, And a horizontal member which is horizontally disposed so that the cable tray is connected to the ends of the bolts.

In addition, a plurality of cable tray support members are installed to fix the cable tray while maintaining a predetermined distance therebetween.

However, such cable trays and supporting members may be severely shaken up, down, left, and right by an external impact such as an earthquake, so that the cable trays may be detached or damaged from the transverse members. In such a case, There is a possibility that an electric very large damage may occur.

In order to solve such a problem, the prior art patents are disclosed in Korean Patent No. 10-1326806 entitled " Patent Literature 1 of Cable Tray Supporting Member ", patent No. 10-1436333 " 2), and the cable tray structure having the earthquake-proof property, as disclosed in Japanese Patent Application No. 10-1759163.

Patent Literature 1, Patent Literature 2 and Patent Literature 3 are provided with a pair of vertical members which are essentially arranged in the vertical direction and horizontal members which are horizontally coupled to the pair of vertical members and which support the cable tray.

However, there is a problem that it is difficult to place the cable on the cable tray in a state where the vertical member is coupled to both ends of the lateral member.

Further, when moving the cable seated in the cable tray to the left or right, there was difficulty in securing the cable due to the friction between the hanger and the cable.

Patent 1: Registration No. 10-1326806 {Registration date: November 01, 2013} Patent No. 2: Registration No. 10-1436333 {Registration date: Aug. 26, 2014} Patent 3: Registration No. 10-1759163 {Registration date July 12, 2017}
