Construction technology of a group nail connection device with corrugated sleeve

Abstract

The invention discloses a construction process of a stud group connecting device with a corrugated sleeve. The construction process includes the following steps that 1, welding studs are welded to a steel girder; 2, reinforcing steel bars in a concrete bridge deck slab are placed, positioned and tied on the steel girder; 3, the metal corrugated sleeve is cut off; 4, the cut metal corrugated sleevesegments are put on welding stud connectors; 5, concrete is poured onto the concrete bridge deck slab; 6, a cement-based material is injected into the metal corrugated sleeve segments; 7, the cement-based material in holes are maintained, and all construction of the stud group connecting device with the corrugated sleeve is completed. The provided construction process of the stud group connectingdevice with the corrugates sleeve can effectively avoid various defects of traditional stud group connectors during construction of concrete bridge deck slabs, the construction is simple, operation is easy, and the overall quality of the device is reliable.

Description

technical field [0001] The invention relates to the technical field of steel-concrete connection in a combined structure with concrete, in particular to a construction technique of a group nail connection device with a corrugated sleeve. Background technique [0002] In steel-concrete slab composite structure bridges, in order to reduce the tensile stress level of the concrete slab in the negative moment zone, prestressed steel beams are often used to apply prestress. In order to improve the efficiency of prestressing, it is necessary to separate the concrete slab from the steel beam when prestressing is applied, and then connect the concrete slab and steel beam through group nails after the prestressing is completed. This group of nail connectors and the steel bars in the bridge deck are interlaced. It is extremely complicated to support the wooden formwork during on-site production. Even if the formwork is made, it is difficult to remove after the concrete slab is poured, ...

Problems solved by technology

This group of nail connectors and the steel bars in the bridge deck are interlaced. It is extremely complicated to support the wooden formwork during on-site production. Even if the formwork is made, it is difficult to remove after the concrete slab is poured, and the quality of the concrete bridge deck with holes is difficult to guarantee.
