Connecting structure of asynchronous cantilever construction steel-concrete joint part and construction method thereof

Abstract

The invention discloses a connecting structure of an asynchronous cantilever construction steel-concrete joint part and a construction method thereof. The connecting structure comprises a corrugated steel plate, a flange plate, perforated rib plates, penetrating steel bars, rubber sleeves, L-shaped steel and a concrete top plate, wherein the corrugated steel plate is welded at the bottom of the flange plate, the flange plate is uniformly and equally divided by the corrugated steel plate at the lower part, and the perforated rib plates are symmetrically welded on the surface of the flange plate; the through steel bars penetrate through the perforated rib plates, the rubber sleeves wrap the through steel bars, the L-shaped steel bars are symmetrically welded to the outer sides of the perforated rib plates, and the concrete top plate wraps all the structures. Under the action of the same load, compared with an original connecting structure, the connecting structure has the advantages thatthe influence of local horizontal shearing force on concrete can be effectively eradicated, concrete at the end is prevented from cracking, and the engineering quality is ensured. And all componentsare symmetrically arranged, so that the construction is simple and convenient, and the influence on the construction progress is little.

Description

technical field [0001] The invention relates to the field of bridge engineering, and relates to a cantilever construction of a corrugated steel web, in particular to a connection structure of a steel-concrete junction in asynchronous cantilever construction and a construction method thereof. Background technique [0002] The structure of the asynchronous cantilever construction hanging basket in bridge engineering is simplified, and its self-weight is reduced. Compared with the ordinary diamond-shaped hanging basket, the action position is moved from the top plate of the poured section to the folded steel web of the section to be poured. The structure of the hanging basket is simplified, and the web The plate is easy to hoist; simply supported on the upper flange plate, it is easy to move; the three working faces are independent of each other, and the construction efficiency is high; the corrugated steel plate bears the load of the hanging basket, giving full play to the util...

Problems solved by technology

However, since the corrugated steel plate is the main load-bearing structure of the construction, the shear stress at the interface between two adjacent sections is relatively large, so the concrete roof is prone to cracks here
