Prefabricated concrete frame structure and construction method

Abstract

The invention provides a prefabricated concrete frame structure and a construction method. The frame structure comprises prefabricated frame column structures and connecting beams, the prefabricated frame column structures comprise prefabricated concrete columns and prefabricated concrete beams, the prefabricated concrete beams and the prefabricated concrete columns are mutually and vertically connected and integrally poured and formed, the prefabricated frame column structures are transversely connected through the connecting beams, connecting parts are embedded into the ends of the prefabricated concrete columns, the prefabricated frame column structures are longitudinally connected through the connecting parts, and concrete is poured to the outer sides of the connecting parts. According to the construction method, a bearing platform is constructed, formworks are constructed, reinforcing steel bars are bound, the connecting parts are embedded, the concrete is poured to obtain the prefabricated frame column structures, steel plates are fed, assembled and welded to obtain H-shaped steel beams, prefabricated frame column structures of one side are hoisted on the bearing platform, prefabricated frame column structures of the other side are hoisted on the bearing platform, the H-shaped steel beams are mounted, connecting parts are fixed, and the concrete is poured. According to the structure and the construction method, formworks and building materials can be saved, construction efficiency is improved, and construction environments are purified.

Description

technical field [0001] The invention relates to the field of construction, in particular to a prefabricated concrete frame structure and a construction method. Background technique [0002] At present, the construction of concrete frame structures mainly relies on the construction of traditional structures, such as transfer stations, concrete frame structure workshops, etc. The concrete frame structure is mainly composed of columns and beams, which are connected by rigid joints or hinges to form a load-bearing system structure, that is, the frame composed of beams and columns jointly resists horizontal loads and vertical loads that occur during use. In the construction, it is necessary to set up a full house scaffolding, and the pouring height of each layer should not exceed 6 meters, and the concrete should be dropped by using string tubes, chutes, chute pipes or vibrating chute pipes. The entire frame structure is generally poured in three or four times, which takes a lon...

AI Technical Summary

Problems solved by technology

The entire frame structure is generally poured in three or four times, which takes a long time, and the formwork and scaffolding take a long time, the number of turnovers is small, and the cost is high
