Embodiment Construction
[0025] As shown in the figure, a prestressed assembled truss-type steel-reinforced concrete structure system includes a steel-reinforced concrete beam segment 1 , a steel-reinforced concrete beam-column node segment 2 and prestressed steel bars 3 prefabricated in a factory. The ends of steel reinforced concrete beam sections and steel reinforced concrete beam-column joint sections are provided with gusset plates for wet joint 4 connection, and the beam sections of steel-reinforced concrete beam sections and steel-reinforced concrete beam-column joint sections are provided with prestressed tunnel.
[0026] The gusset plates are connected by high-strength bolts and then concrete is poured to form wet joints 4. Prestressed steel bars are pierced in the prestressed channels and anchored and fixed with anchors to form an overall frame structure system.
[0027] The prestressed tunnel is arranged in an undulating shape, located at the lower part at the mid-span, and at the upper par...

A prestressed assembled truss-type steel-reinforced concrete structure system and its assembly method, which are composed of steel-reinforced concrete beam sections, beam-column node sections, prestressed steel bars, anchors, etc., and the steel-frame truss should be able to bear the structure's own weight and construction Various loads appearing in the first stage, the prestressed steel bars are used to bear the second-stage dead load and live load, and improve the structural integrity and crack resistance control requirements. The invention can greatly improve the degree of industrialization and assembly of the steel-reinforced concrete structure, facilitate construction, accelerate the construction speed and production efficiency of the structure, save the construction period and project cost, and reduce the component size of the long-span structure by applying prestress Size, increased structural strength, improved structural integrity and crack resistance.
Description
technical field [0001] The invention relates to a frame structure system, in particular to a prestressed assembled truss type steel-reinforced concrete structure system and an assembly method thereof. Background technique [0002] In 1974, the "Guidelines for the Government's Policies and Measures for the Gradual Realization of Construction Industrialization" published by the United Nations defined the construction industrialization as the process of transforming the construction industry according to the large-scale industrial production mode, so that it gradually shifted from handicraft production to socialized large-scale production. The implementation process That is, standardization of architectural design, industrialization of component production, mechanization of construction, and scientific organization and management, and the gradual adoption of new achievements in modern science and technology to increase labor productivity, speed up construction, reduce engineerin...
