EARTHQUAKE-PROOF TYPE CABLE TRAY AND DUCT SYSTEM OF WIRE BASE FOR EARTHQUAKE-PROOF DESIGN

摘要

The present invention relates to a support structure for an wire-based earthquake-resistant cable tray and duct. The support structure for an wire-based earthquake-resistant cable tray and duct according to the present invention may comprise: cylindrical bars (110) which are arranged in a width-wise direction (W) perpendicular to a length-wise direction (L) of a cable tray or duct (1), which support the cable tray or duct (1) in the width-wise direction (W), and which are spaced apart from one another in the length-wise direction (L) of the cable tray or duct (1); and first tension wires (120), opposite ends of each of which are connected to two of a plurality of tension hooks (130) corresponding to a pair disposed in the length-wise direction (L) of the cable tray or duct (1) when each adjacent two of the tension hooks (130) is inserted into a surface of a ceiling constitute the pair; each of which surrounds a corresponding one of the cylindrical bars (110) disposed at a center of two of the tension hooks (130), corresponding to the pair, in the length-wise direction (L); and each of which performs force distribution in the length-wise direction (L) of the cable tray or duct (1). Accordingly, provided is an effect in which damage attributable to an earthquake can be prevented by using a hanging method rather than a conventional supporting method. According to the present invention, support against vibration of an architectural structure in overall directions of X-, Y-, and Z-axes depends on tension force of wire, thereby providing an effect of provision of a structure in which a wire disposed in a direction opposite to a moving direction is pulled. Furthermore, according to the present invention, force is applied to wire as tensile force, and the force is distributed to an architectural structure in vertical and horizontal directions, thereby providing an effect of reduction of stress applied to the architectural structure.
