Problems solved by technology

Insufficient bonding between the corrugated steel web and the lining concrete may easily lead to cracking of the lining concrete, which will reduce the bearing capacity of the structure, cause excessive deflection of the box girder, cause redistribution of internal forces in the structure, and reduce the service life of the bridge. The normal use function of the structure, the durability and safety of the structure will be adversely affected, and even cause major economic losses and serious traffic accidents

Abstract

The invention discloses a corrugated steel web plate and lining concrete connecting system, a bridge and a method. The system comprises shear connecting pieces. The operation method sequentially comprises the steps that groove-shaped angle steel is prefabricated in a factory, the groove-shaped angle steel is vertically welded on the inner side of corrugated steel web plates, through-reinforcing steel bars are laid in grooves of angle steel, and lining concrete of the corrugated steel web plates is poured. According to the corrugated steel web plate and lining concrete connecting system, the bridge and the method, by replacing connecting pieces such as studs and perforated plates by vertically welding the shear connecting pieces on the inner side of the corrugated steel web plates, the contact area and anchoring length of the corrugated steel web plates and the lining concrete are enhanced, the adhesion stress between the two is enhanced, the anti-split ability of the steel web plates and the concrete is improved, the integrity of the structure is enhanced, and the cracking of the lining concrete is prevented; and the amount of welding work is reduced, the through-reinforcing steelbars are laid by using the grooves of the angle steel, and the grooves of the angle steel anchors longitudinal steel bars in the grooves to enhance the bolt pin action of bending steel bars and fullyexert the bonding performance between the steel bars and the concrete.

Description

technical field [0001] The invention relates to the structural design field of PC composite box girders with corrugated steel webs, and in particular designs a connection system and method for corrugated steel webs and lining concrete and a bridge using the connection system. Background technique [0002] Corrugated steel web PC composite box girder refers to a steel-concrete composite bridge structure in which corrugated steel webs are used instead of concrete webs, and the top and bottom plates still use reinforced concrete structures. When the span of the bridge is large, considering the design requirements of the high-span ratio, the girder height at the root and fulcrum of the box girder section will be increased accordingly, in order to balance the self-weight of the side span and main span structure, and improve the buckling resistance of the corrugated steel web. To prevent stress concentration at the connection between the corrugated steel web and the lining concret...
