A safe and reusable reinforced concrete frame structure and connection method

Abstract

The invention discloses a safe and reusable reinforced concrete frame structure and a connection method, comprising a reinforced concrete foundation, a limit mechanism, a steel connection plate, a connection positioning mechanism, high-strength friction bolts, a positioning connection steel plate, and a fixed connection screw cap , prefabricated concrete girder, limit connection mechanism and prestressed tendons. The invention adopts the connection between the limit mechanism, the steel connecting plate and the prefabricated reinforced concrete member, which improves the construction efficiency. The frame structure does not need any cast-in-place concrete, no form support, and the structural members are easy to dismantle and maintain after the earthquake. The rapid restoration of structural functions, and the overall earthquake resistance of the frame structure are easy to upgrade or enhance the safety of the structure by replacing weaker building components with larger and stronger building components or adding steel supports.

Description

technical field [0001] The invention relates to the technical field of concrete member connection, in particular to a safe and reusable reinforced concrete frame structure and a connection method. Background technique [0002] According to a utility model patent of Chinese Patent No. CN201820900254.2, the utility model discloses a reinforced concrete frame connection structure, including reinforced concrete columns, at least two reinforced concrete frame beams, at least one first reinforced concrete floor slab and at least one The second reinforced concrete floor slab, each reinforced concrete frame beam is fixedly connected to the reinforced concrete column, each first reinforced concrete floor slab is connected between two adjacent reinforced concrete frame beams, and each first reinforced concrete floor slab faces the reinforced concrete There is a distance between one end face of the column and the column edge of the reinforced concrete column, each second reinforced con...

Problems solved by technology

[0004] However, the construction methods of reinforced concrete structures are currently mostly cast-in-place or assembled integrally, so that the beams, slabs, and columns are connected as a whole, and the seismic performance is good, but the later demolition and maintenance are inconvenient and costly. Components cannot be reused, and a large amount of solid waste is generated, which brings harm to the environment and causes a huge waste of resources;

[0005] At the same time, the integral reinforced concrete frame structure is assembled, and the column and foundation, column and column are connected by sleeve grouting or inserted into the cup. Afterwards, many problems were exposed: the quality of grouting is not easy to control, the installation speed is slow, and the on-site installation of steel bars in the core area of ​​​​beams and columns is difficult. This requires the development of a new type of dry joint that is convenient for integral connection. production process, so a safe and reusable reinforced concrete frame structure and connection method are needed to solve the problems raised in the above-mentioned background technology
