Description
Technical Field
The utility model relates to a steel frame construction technical field, in particular to prefabricated shaped steel concrete column and girder steel connected node.
Background
The steel frame structure is a structure mainly formed by connecting steel members (steel beams and steel columns), and is one of the main building structure forms at present. Compared with a reinforced concrete frame structure, the steel frame structure has the characteristics of light self weight, good anti-seismic performance, short construction period and the like, and is widely applied to large-span and high-rise buildings. When the stress analysis of the whole structure is carried out, the structural form of the beam-column joint has direct influence on the strength and the rigidity of the joint and the stability and the shock resistance of the whole structure, and also has indirect influence on the construction progress and the construction cost, so the design of the beam-column joint is very important. Practical application finds that a large number of brittle fracture occurs at beam-column connecting nodes of a steel frame building, so that plastic deformation of main structural components of the structure is not completely developed, and the whole structure loses bearing capacity due to brittle failure, so that life and property losses are not negligible. In addition, according to the design requirement of 'strong column and weak beam', the actual bending bearing capacity of the column end is greater than that of the beam end. The steel has good ductility, light dead weight and good earthquake resistance, but is easy to generate larger horizontal displacement and has poor fireproof performance. In order to improve the bearing capacity of the steel column, the section area of the steel column is often increased, but the available area in a house is influenced by the overlarge section of the column.
At present, the assembled building is widely popularized and developed at home and abroad, and the characteristics of light weight and high strength of a steel structure are perfectly fit with the development concept of the assembled building. The assembly type building transfers most of work to a factory, structural members are produced in a factory, and meanwhile, on-site mechanical hoisting and splicing are carried out, so that the construction environment is improved, the construction error is reduced, and the installation and construction efficiency is improved. The assembled steel frame structure overcomes the influence of welding seams, and parts connected by beam-column joints are directly assembled on a construction site through batch production in a factory. The mode improves the construction speed, is convenient for the disassembly of the components, can reutilize the disassembled steel, and is a very environment-friendly construction mode. The section steel concrete column is a combined structure with section steel configured in the concrete, and is divided into a solid-web type and a hollow-web type according to different forms of the configured section steel. The steel reinforced concrete column has the advantages of high bearing capacity, high rigidity, strong fireproof performance and the like, fully utilizes the bearing capacity of two materials through the synergistic effect of steel and concrete, and has excellent earthquake-resistant performance. Because the section steel concrete column has the characteristics of high bearing capacity and high rigidity, the section area of the column body of the section steel concrete column is smaller than that of the steel column under the condition of ensuring the same strength, and the indoor use area is enlarged. In addition, because the section steel is wrapped by concrete, the section steel is not easy to corrode and has good fireproof performance. The existing connection mode is mainly used for connecting the steel beam and the steel column, and the research on the prefabricated section steel concrete column and the steel beam node is very rare.
