Hollow plate hinge joint structure with anchoring plates and construction method thereof

Abstract

The invention relates to a hollow plate hinge joint structure with anchoring plates and a construction method thereof. The hollow plate hinge joint structure with the anchoring plates comprises a hinge joint arranged between adjacent hollow plates; connecting reinforcements with the anchoring plates are arranged in the hinge joint in the longitudinal direction in a spaced manner; two longitudinalreinforcements connected with the lower parts of the connecting reinforcements are arranged at the lower part of the hinge joint in the longitudinal direction; inclined reinforcements with the anchoring plates, which are used for connecting the hollow plates with the longitudinal reinforcements, are correspondingly arranged on the two sides of the lower part of the hinge joint in the longitudinaldirection in a spaced manner; and a bridge deck pavement for filling the hinge joint is laid above the hollow plates. According to the hollow plate hinge joint structure with the anchoring plates, thestandard construction is made convenient, and the anti-shear and anti-bending ability of the connecting part of the hinge joint is greatly improved.

Description

technical field [0001] The invention relates to a hinged joint structure of a hollow plate with an anchor plate and a construction method thereof. Background technique [0002] The horizontal connection structure must be adopted between the hollow slab bridge plates to ensure that the plates bear the vehicle load together. However, due to the small size of the concrete structure at the hinged joints, post-casting, and the complex structure of the hinged joints, the construction quality of the hinged joints in the upper structure is the most difficult to guarantee. The existing hinged joint structure has insufficient shear resistance of the connecting steel bars, and the construction quality of the concrete at the hinged joint is poor, and damage occurs earlier, which eventually results in the stress of the veneer. The stress state of the veneer is very harmful to the bridge and has a wide range. In addition to causing damage to the beam itself, it can also cause damage to t...
