Problems solved by technology

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

Abstract

The invention discloses a group nail connecting device with a corrugated sleeve, which comprises a group nail connector and a corrugated sleeve, the group nail connector includes a plurality of welding studs, and the corrugated sleeve is sleeved on the welding studs , the gap between the corrugated sleeve and the welding stud is filled with mortar; the corrugated sleeve is staggered with reinforcement mesh. The group nail connection device with the corrugated sleeve provided by the invention makes the construction of the steel-concrete slab composite structure bridge simple, high in quality and good in construction effect.

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 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, and 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 p...
