Fabricated fully-prefabricated concrete frame structure system and construction method

Abstract

An assembly type fully-prefabricated concrete frame structure system comprises prefabricated frame columns, prefabricated laminated beams, structural main reinforcements, structural stirrups, frame column grouting sleeves, prefabricated laminated plates, prefabricated outer wall heat preservation integrated plates and a foundation platform. A superposed beam connecting assembly formed by fixedly connecting one to four U-shaped supporting pieces which are correspondingly arranged is embedded in the upper portion of the prefabricated frame column. The U-shaped supporting piece comprises a U-shaped groove, an inner side pulling steel plate and an outer side pulling steel plate, wherein the inner side pulling steel plate and the outer side pulling steel plate are connected between groove openings of the U-shaped groove. Frame column stirrup preformed holes are correspondingly formed in the two sides of the U-shaped groove; frame column main reinforcements penetrating through the U-shaped grooves and the inner side tie steel plates are further arranged in the prefabricated frame columns; frame column stirrups penetrating through the frame column stirrup preformed holes are further arranged in the prefabricated frame column; superposed beam end plug-in units are pre-buried at the two ends of the prefabricated superposed beam, and the superposed beam end plug-in units are in plug-in fit with the U-shaped supporting pieces. The purposes that the prefabricated assembly type structure is easy and convenient to install, efficient, rapid, safe, reliable and controllable in cost are achieved.

Description

Technical field [0001] The present invention belongs to the construction area, and specifically involves an assembled full prefabricated concrete frame structure system and method. Background technique [0002] Cast - in - place concrete frame structure, the core force node is the core area of ​​the beam column. The assembled frame structure, the construction form of the factory prefabricated component on-site installation, its core technology is still the connection problem of the force part of the core area of ​​the beam column. The beam column node as a thinner of the structure of the structure, but also the main reason for restricting the promotion of assembled structures. [0003] Cast - in - place concrete frame structure, the core force node is the core area of ​​the beam column. The assembled frame structure, the construction form of the factory prefabricated component on-site installation, its core technology is still the connection problem of the force part of the cor...

Problems solved by technology

[0006] The second type: semi-prefabricated frame structure, which uses prefabricated components to reserve the core area of ​​beams and columns. The frame beams and laminated slabs are hoisted with full support, and the overall pouring method in the later stage requires a lot of work for the support system. Compared with traditional cast-in-place steel bars The cost of the concrete structure has been greatly increased, and there is no obvious promotion advantage, and the main reinforcements reserved for prefabricated frame beams in all directions are concentrated and staggered in the core area, and the frame column stirrups are bound in the later stage. The overall construction is more difficult than on-site binding.

[0007] At the same time, the above two prefabricated structural systems have greatly improved the cost compared with the cast-in-place concrete frame structure, which is not conducive to the development and promotion of prefabricated buildings.
