Fabricated frame structure combination system and construction method thereof

Abstract

The invention provides a fabricated frame structure combination system and a construction method thereof. The fabricated frame structure combination system comprises at least one precast floor slab, at least two bracket composite beams, and at least four composite columns, wherein each bracket composite beam comprises a U-shaped mold shell, a beam rebar assembly and two protrusion parts which arearranged on the outer side of the opening end of the U-shaped mold shell and are flush with the U-shaped opening end, and the beam rebar assembly is at least partially embedded in the U-shaped mold shell and the protrusion parts; the two ends of each precast floor slab are in butt joint with the protrusion parts located on the adjacent sides of every two bracket composite beams; each composite column comprises a column shell, a cavity defined by the column shell, and a column rebar assembly; and the two ends of the bottom of the U-shaped mold shell of each bracket composite beam abut against the outer sides of the top ends of the two corresponding column shells, and the bracket composite beams are perpendicular to the composite columns. The invention further provides the construction method of the fabricated frame structure combination system. According to the fabricated frame structure combination system and the construction method thereof, the weight of a precast component is lowered, the filed machine lifting pressure is reduced, vertical supporting is omitted, and the field rebar operation quantity is decreased.

Description

technical field [0001] The present disclosure relates to the field of prefabricated buildings, in particular to a prefabricated frame structure combination system. Background technique [0002] One of the important measures for the country to promote the development of construction industrialization and the transformation and upgrading of the construction industry is to promote the research and application of key technologies in the aspects of building structure system, architectural design, parts and accessories. New prefabricated structural systems are in full bloom, but most of the prefabricated components of the structural system are too heavy, have a large modulus on site, require a lot of manual work on site, and have a low degree of industrialization. Especially public buildings with high storey height and large span need to build a very dense vertical support system during on-site construction, and at the same time require a large number of formwork.

Problems solved by technology

New prefabricated structural systems are in full bloom, but most of the prefabricated components of the structural system are overweight, have a large amount of on-site support modulus, a lot of manual work on site, and a low degree of industrialization

Especially public buildings with high storey height and large span need to build a very dense vertical support system during on-site construction, and at the same time require a large number of formwork. If traditional prefabrication is used, the weight of a single component is very large, and the requirements for hoisting equipment Very high, slow installation speed, difficult to control construction safety
