Grouting steel pipe connection device structure and connection method

Abstract

The invention relates to the field of steel structure buildings, in particular to a grouting steel pipe connection device structure and a connection method. The produced grouting steel pipe connection device can be used for connecting steel pipe structures in the steel structure buildings. The steel pipe connection method adopting the grouting steel pipe connection device can serve as the method for connecting the steel pipe structures in the steel structure buildings. The structure comprises a high-strength steel bar with anchor hooks, an anchorage positioning steel plate, steel bar penetrating holes, an inner clamping ring, a lower connected steel pipe, a grouting hole and an upper connected steel pipe. By arranging the grouting steel pipe connection device between the ordinary connected steel pipes, the steel pipes are connected through a grouting method. The grouting steel pipe connection device can be prefabricated in a plant. Welding is not needed during on-site construction, the connection structure is simple, the requirement for the technical level of constructors is not high, the on-site construction difficulty is low, the construction quality can be guaranteed easily, environmental friendliness is achieved, energy is saved, and the requirement for current green buildings is better met.

Description

technical field [0001] The invention relates to the field of steel structure construction, and specifically relates to a structure and a connection method of a grouting connection steel pipe device. The produced grouting connection steel pipe device can be used to connect steel pipe structures in steel structure buildings. The steel pipe method can be used as a method for connecting steel pipe structures in steel structure buildings. Background technique [0002] Steel structure buildings have the advantages of light weight, high strength, and good seismic performance, and have become one of the important development directions of contemporary and future buildings. In the steel structure, due to factors such as transportation and hoisting, the length of the steel pipe is limited, and the connection of the steel pipe is inevitable. The traditional steel pipe connection mainly adopts weld seam connection, which has disadvantages such as large welding residual stress at the co...

Problems solved by technology

The traditional steel pipe connection mainly adopts weld seam connection, which has disadvantages such as large welding residual stress at the connection point, poor seismic performance, high technical level requirements for construction personnel, difficult on-site construction, and difficulty in guaranteeing construction quality.

In the construction of steel structures, especially curtain wall steel structures, the application is very inconvenient
