Problems solved by technology
[0002] The construction of traditional long-span multi-storey building projects usually adopts layered hoisting, the cost of using cranes is high, and the construction progress is slow. Some prefabricated beams need to use large-tonnage cranes due to their heavy weight, but due to the design bearing capacity of the floor, large-tonnage cranes cannot be used. Crane operation, resulting in the failure of hoisting construction of prefabricated beams in multi-storey building projects
The existing patent (application number: 201210291475.1) discloses a large-span prefabricated monolithic structure and its construction method. Although multiple layers of prefabricated beams can be hoisted at the same time during the construction stage, the amount of steel used for the lattice columns is large and the rigidity is small. Prefabricated beams are difficult to install on the resting surface, which affects the construction progress
A steel-concrete combined structure system and construction method with high-strength concrete poured into limb columns, lattice columns and column caps with large bearing capacity have not been reported

The invention discloses a steel and concrete combined structure system and a construction method. The steel and concrete combined structure system comprises a lattice-type steel-reinforced concrete composite column with a column cap, a prestressed superposed beam and a steel bearing plate combined floor; and the lattice-type steel-reinforced concrete composite column with the column cap includes alattice-type steel-reinforced column and a reinforced concrete column body, the steel and concrete combined structure system is characterized in that the lattice-type steel-reinforced column includeslimb columns and a web rod, the limb columns are steel pipes located at four corners of the lattice-type steel-reinforced column, the inside of the steel pipes are filled with high-strength concrete,and the column cap is composed of a profiled steel component and outer coating reinforced concrete. The high-strength concrete is poured into the lattice-type steel-reinforced column limb column steel pipes, the amount of adopted steel is reduced, the rigidity is increased, multiple layers of precast beams can be hoisted at the same time, the construction progress is increased, and hoisting costsare saved.
Description
technical field [0001] The invention relates to a structural system and a construction method of a building, in particular to a construction method of a steel and concrete composite structure. Background technique [0002] The construction of traditional long-span multi-storey building projects usually adopts layered hoisting, the cost of using cranes is high, and the construction progress is slow. Some prefabricated beams need to use large-tonnage cranes due to their heavy weight, but due to the design bearing capacity of the floor, large-tonnage cranes cannot be used. The crane operation made it impossible to hoist the prefabricated beams of the multi-storey building project. The existing patent (application number: 201210291475.1) discloses a large-span prefabricated monolithic structure and its construction method. Although multiple layers of prefabricated beams can be hoisted at the same time during the construction stage, the amount of steel used for the lattice column...
