Description

TECHNICAL FIELD

[0001] The present application relates to the field of prefabricated buildings, in particular to an efficient connecting component of prefabricated buildings. BACKGROUND

[0002] As a new type of building method, prefabricated buildings have developed rapidly in recent years. The core is to divide the building into multiple prefabricated components, which are transported to the site for assembly after production in the factory. This construction method has the advantages of fast construction speed, small environmental pollution, controllable quality, etc., and has become an important direction for the transformation and upgrading of the construction industry. However, the connection technology between prefabricated components is still one of the key bottlenecks restricting the development of prefabricated buildings. The connection methods commonly used in the industry at present include welding, bolt connection, sleeve grouting connection, etc. These technologies have their own characteristics but also have certain limitations; The specific solutions of the prior art are generally divided into three types: welding connection: connecting components by high-temperature melting of metal, the advantages are high connection strength, the disadvantages are large heat-affected zone, easy to produce deformation, need professional welder operation and not convenient to disassemble. Bolt connection: using mechanical fasteners to connect, the advantages are simple construction, disassembly, the disadvantages are complex connection nodes, poor seismic performance and need regular maintenance. Sleeve grouting connection: inserting steel bars into the reserved holes of prefabricated components and pouring high-strength mortar, the advantages are good integrity, the disadvantages are long curing time, quality is not easy to control and cannot be reused, at the same time, the existing technology usually has some defects: the existing connection technology generally has low construction efficiency, unstable connection quality, insufficient seismic performance, and cannot be reused, which seriously restricts the promotion and application of prefabricated buildings, especially in high-rise buildings and large-span structures, the strength, stiffness and ductility requirements of the connection nodes are higher, and the traditional connection method often cannot meet the demand SUMMARY The purpose of the present application is to solve the problems of low construction efficiency, low connection strength, poor seismic performance and low component reuse rate in the prior art, and to provide an efficient connecting component of prefabricated buildings. The efficient connecting component of prefabricated buildings comprises a first prefabricated component and a second prefabricated component, both of which are factory prefabricated components, the bottom of the first prefabricated component is provided with an upper connecting plate through welding, the top of the second prefabricated component is provided with a lower connecting plate through pre-burying, a connecting mechanism is arranged between the upper connecting plate and the lower connecting plate, the bottom of the upper connecting plate is fixedly connected with a second threaded block, the top of the lower connecting plate is fixedly connected with a first threaded block, a locking mechanism is arranged on the connecting mechanism, and a buffer mechanism is arranged on the connecting mechanism.
