The invention provides a pipe truss structure integral lifting device. The pipe truss structure integral lifting device is characterized by comprising an upper hoist point lifting module arranged on the top of an integral pipe truss structure, a fixing steel strand module arranged at an upper chord of the integral pipe truss structure, an upper chord clamping module connected with the fixing steel strand module, a lower chord clamping module arranged at a lower chord of the integral pipe truss structure and a connecting rod piece used for connecting the upper chord clamping module with the lower chord clamping module. By the adoption of the design, the pipe truss structure integral lifting device is simple in structure, convenient to manufacture and install and capable of being applied to integral lifting operation of a pipe truss with a large span and a complex structure, thereby effectively shortening the installation and construction period of a complex spatial structure and greatly lowering construction cost.
Description
technical field [0001] The invention relates to the field of overall lifting of large-span steel trusses, in particular to an overall lifting device for pipe truss structures. Background technique [0002] Due to the characteristics of large span, structural safety and complex shape, architectural steel structures are more and more favored by the people. The installation of traditional steel structures mostly adopts the high-altitude construction technology of full-scale scaffolding, and the measures used are relatively expensive. In recent years, for some complex space structures, in order to shorten the construction period and save engineering costs, the overall lifting technology of steel structures has been applied in the installation of steel structures. The accuracy of the block hoisting method is difficult to control, and there are great potential safety hazards in the hoisting process. Contents of the invention [0003] The object of the present invention is ...
