Gluing shear connector and construction method thereof

Abstract

The invention discloses a gluing shear connector and a construction method thereof. The gluing shear connector comprises one or more main rods, a base and a gluing layer, the lower end or lower ends of one or more main rods is / are all fixedly connected to the top surface of the base, and the bottom surface of the base is fixedly connected to a steel bridge deck through the gluing layer. The base is a flat plate or a variable thickness plate which is thick in middle and thin in surrounding, and a grain is carved on the bottom surface of the base. The gluing layer is sufficiently embedded into the grain of the bottom surface of the base, and the gluing layer and the bottom surface of the base are firmly glued for a long term. By increasing the area of the base of the shear connector, the reliable connection of the shear connector and a steel structure is achieved in a gluing method, thermal stress does not need to be input, the stress performance, particularly anti-fatigue performance, of the steel structure can be effectively improved, then the excellent function of resisting pulling while not resisting shearing can be achieved in steel bridge deck pavement structure application; meanwhile, reinforcing and replacing of a bridge pavement structure can be facilitated, the construction is convenient, the economy is good, and the running and maintaining cost of the bridge pavement structure in the later period is effectively lowered.

Description

technical field [0001] The invention belongs to the technical field of bridge engineering, in particular to the field of steel-concrete composite structures, and relates to an adhesive shear-resistant connector and a construction method thereof. Background technique [0002] The steel-concrete composite structure guarantees the common stress between the steel structure and the concrete structure through the connectors, and has been widely used in engineering, such as Nanpu Bridge, Yangpu Bridge, Donghai Bridge, Shanghai Yangtze River Bridge, Wangdong Bridge, irrigation River Bridge etc. Welding stud connectors and perforated plate connectors are two kinds of connectors widely used in steel-concrete composite structures, both of which are connected to steel structures by welding. The welding method can ensure the reliable connection between the connector and the steel structure, but the thermal stress will be input into the steel structure during the welding process, which w...

AI Technical Summary

Problems solved by technology

In addition, for the steel bridge deck pavement structure using cement-based materials, due to the different service life of the steel structure part and the pavement structure, the bridge deck pavement needs to be replaced during the operation process, and it is difficult to remove the welding stud connectors using traditional welding methods. Large, which brings great difficulties to the operation and maintenance of the pavement structure in the later stage
