Holding apparatus of cable tray

Abstract

The present invention relates to a cable tray fixing device for construction that enables the convenient installation of multiple cable wirings by installing a rung member forming a cable tray between walls of buildings positioned facing each other. The characteristic configuration thereof is a cable tray fixing device used by positioning a rung member, which has multiple cable wiring holes provided on its upper surface, between walls of buildings facing each other, wherein a pair of coupling grooves are formed facing each other on both sides of the rung member, multiple support grooves are formed at the lower center portion, a pair of fitting grooves are formed facing each other on a portion adjacent to the coupling grooves, multiple coupling holes for bolt connection are formed on a portion corresponding to the wall, multiple support plates connected by elastic springs are provided at regular intervals in the longitudinal direction on the rear surface that is in close contact with the wall, and an installation plate is provided on the front surface having an elongated guide hole formed in the vertical direction at the inner center portion, a connecting hole communicating with the guide hole formed on one side, and multiple seating grooves formed at regular intervals in the longitudinal direction on the front surface, thereby positioning one on the front surface of the facing wall. A pair of wall mounting plates spaced apart and facing each other, a guide ball inserted into and guided by the guide hole provided on the rear side, and a coupling pin protruding from the front side that engages with the coupling groove, thereby fixing a rung member positioned between the wall mounting plates positioned facing each other; a pair of seating protrusions engaged with the seating groove provided on both ends, a pair of contact plates protruding facing each other on the outer diameter rim portion adjacent to the seating protrusions, a pair of support springs engaged facing each other on the portion adjacent to the contact plates, a pair of connecting grooves formed on the portion adjacent to the support springs corresponding to the fitting groove, and a plurality of insertion holes connected by connecting springs to insertion plates engaged with the support grooves provided on the center portion of the upper surface, with both sides connected to a pair of wall mounting plates positioned facing each other and installed to support the lower end of the rung member;The cable fixing plate comprises a pair of catch bars that are fitted and coupled into the above-mentioned fitting groove and connecting groove, and at their lower ends are provided catch plates with their upper surfaces in close contact with the lower surface of a rung member support plate in which the connecting groove is formed, and a cover plate having a plate shape connecting the upper surfaces of the catch bars, with a plurality of cover plates at their lower ends provided at regular intervals to surround the upper surface of the cable wiring hole.
