摘要

the utility model belongs to the field of industrial and civil construction, namely, to облицовочным hinged communication panels.used for the sewing of plumbing and electrical communication mines (nis), providing a quick disconnect and access to engineering communications.the lining sheet of a communication is metal or plastic, which contains the upper and lower panels, between them are medium-sized panelsсостыкованные among themselves through the thorn - paz, each panel consists of a median part and плоскостной завальцованных edgesin the middle and bottom panels form the завальцованные paz, on the sides of the groove are formed with holes for fasteners and fastening elements, the lower завальцованные edges form a thornthe upper and lower panels in the ground floor and the ceiling have примыкания latch - clamps. the technical result is to reduce the labour intensity of installation engineering of communications and services.
