Back ridge supporting workpiece

The utility model relates to the technical field, in particular to a back ridge supporting workpiece which comprises an abutting assembly and a fastener, and the fastener is in threaded connection with the abutting assembly. The double-pipe back ridge overcomes the defect that in the prior art, the double-pipe back ridge is bent and deformed due to large torsion, the double-pipe back ridge can be supported between a prefabricated wall and the double-pipe back ridge, and bending deformation of the double-pipe back ridge in the fastening process is reduced by shortening the distance between a screw fastening point and a stress fulcrum of the double-pipe back ridge; the installation position of the workpiece can be adjusted at will according to actual needs, and disassembly and assembly are easy. The device is simple in structure, small in size and weight, convenient to transport, reusable and high in practicability and applicability. 本实用新型涉及技术领域，更具体的，涉及一种背楞支撑工件，其包括抵接组件和紧固件，所述紧固件与所述抵接组件螺纹连接。本实用新型克服了现有技术中双管背楞因受较大
