Description

Technical Field

[0001] The invention relates to the technical field of truss installation, and in particular to a supporting device and an installation method. Background Art

[0002] Steel structures are characterized by high strength, good ductility and plasticity, and are widely used in many construction fields. For steel structures with large spans and large cantilevers, since it is impossible to complete the installation in one go, it is usually necessary to split a truss into multiple sections, hoist them in sections, and connect them at high altitude to complete the installation of a truss.

[0003] Before the trusses are connected, the center of the trusses bends downward due to the deadweight of the structure. Usually, multiple support frames are fixed in the span direction of the trusses to support the trusses, and then removed after the installation is completed. Specifically, the arch point of the truss is first arched to a certain height, and then the height of the arch point of the truss is lowered by gradually lowering the height of the support frame until the position of the truss meets the design value. However, for truss structures with relatively large sizes, it is easy to shake during the unloading process, and even tilt and overturn, which poses a danger to operators. Summary of the invention

[0004] In view of this, the present invention provides a supporting device and an installation method to solve the problem that the truss structure is prone to shaking, or even tilting and overturning during unloading, causing danger to operators.
