Construction method of novel assembled mixed frame structure system

Abstract

The invention relates to a construction method of a novel assembled mixed frame structure system. The construction method comprises a foundation, a prefabricated concrete superposed beam, a steel deckcombined floorslab and a thin-walled steel pipe concrete combination column. The thin-walled steel pipe concrete combination column comprises a U-shaped steel bracket of a joint, a thin-walled steelpipe and steel pipe inner concrete. The prefabricated concrete superposed beam comprises a prefabricated beam and a cast-in-place part. The method can be used for hoisting the prefabricated beams of the multilayered frame structure system simultaneously by adopting a stepped construction method, so that the construction progress is accelerated and the cost is lowered.

Description

technical field [0001] The invention relates to a construction method of a structural system of a building, in particular to a construction method of a novel assembled hybrid frame structure system. Background technique [0002] The traditional multi-story steel frame structure system usually uses steel columns and steel beams as vertical and horizontal stress components, which have problems such as high cost, poor fire and corrosion resistance, and high maintenance costs in the later period. If the steel pipe concrete composite column is used as the vertical component, the wall thickness of the steel pipe will be relatively large, and the amount of steel used will be large. For projects with small storey height, small span and small load, the prefabricated reinforced concrete frame structure system is generally adopted, but the column construction process is complicated, and the beam can only be hoisted layer by layer, the progress is slow, the cost is high, and the reinfor...

Problems solved by technology

[0002] The traditional multi-story steel frame structure system usually uses steel columns and steel beams as vertical and horizontal stress components, which have problems such as high cost, poor fire and corrosion resistance, and high maintenance costs in the later period. If the steel pipe concrete composite column is used as the vertical member, the wall thickness of the steel pipe will be relatively large, and the amount of steel used will be large.

For projects with small storey height, small span and small load, the prefabricated reinforced concrete frame structure system is generally used, but the column construction process is complicated, and the beam can only be hoisted layer by layer, which is slow in progress and high in cost. Collision, inconvenient construction

A construction method of a new type of prefabricated hybrid frame structure system with large bearing capacity of composite columns, prefabricated beams that can be hoisted in multiple layers, convenient construction of joints, and low cost has not been reported
