[0002] As an important component for supporting and fixing various pipelines, cable trays and other facilities in building mechanical and electrical systems, the comprehensive support and hanger generally adopts channel steel as the support and hanger frame and uses expansion bolts to be fixedly connected with the composite slab. The bearing capacity of the expansion bolt is limited, and it may not meet the requirement of long-term stable bearing for some heavy equipment or large pipeline systems, especially under heavy dynamic load. In addition, the installation precision is not easy to control. When the expansion bolt is installed, the depth, perpendicularity and position of the drilled hole need to be accurately controlled, otherwise problems such as non-vertical and eccentric installation of the expansion bolt may occur, affecting the installation precision and stability of the support and hanger. Especially in some high-altitude operations or narrow spaces, the construction difficulty is greater, and the installation precision is more difficult to guarantee. The construction efficiency is low. The expansion bolt needs to be drilled, hole cleaned and bolted, and the operation is relatively complicated. Especially in large-scale construction, a large amount of time and manpower is consumed, and the construction efficiency is reduced. In addition, various pipelines are generally pre-buried in the composite slab, and the pre-buried pipelines may be damaged during the installation of the expansion bolt, resulting in great difficulty in repairing in the later period.
