Embodiment Construction

[0017] Further description will be given below in conjunction with the embodiments shown in the accompanying drawings.

[0018] figure 2 The combined steel plate shown includes a strip-shaped steel plate 1 and two steel backing plates 2; one side of the backing plate is directly attached to the bottom surface of the plate beam 5, and the strip-shaped steel plate is covered on the backing plate, and then respectively bolted 3 (preferably chemical bolts) Fasten the strip steel plate and the backing plate to the plate girder one by one. Due to the use of chemical bolts (purchased), the bolts have the role of anchor rods.

[0019] In order to ensure the connection strength, the bolt fixing part needs to have a certain distance from the edge of the plate girder; for this reason, the distance between the bolt hole and the hinge joint is at least 5 times larger than the bolt hole diameter. Therefore, after the strip-shaped steel plate crosses the hinge joint transversely, the dist...

Abstract

The invention relates to a bridge hinge joint reinforcing method through transverse anchoring steel plates, and aims to improve loading resistance of bridge plates effectively and construct without interrupting traffic. The method has the advantages that construction is facilitated and rapid, and construction quality is easy to guarantee. According to the technical scheme, the bridge hinge joint reinforcing method through the transverse anchoring steel plates sequentially includes 1, cleaning the beam bottom edge portion; 2, adopting bolts to fix a plurality of sets of combined steel plates which cross hinge joints to connect two plate beams integrally on the two plate beams. Each set of combined steel plates comprises a strip steel plate and two backing plates respectively clamped between the plate beams and the strip steel plate.

Description

technical field [0001] The invention relates to a building construction method, in particular to a method for reinforcing bridge hinge joints. Background technique [0002] The bridge hinge joint refers to the post-cast concrete (filling joint) between the prefabricated slab girders in bridge engineering. It connects two slab girders and is carried out after the slab girders are installed and before the bridge deck pavement construction. In the existing prefabricated hinged bridges, there is generally insufficient transverse joint stiffness, which results in the stress of a single main girder, which aggravates the damage of the bridge; Reasonable reinforcement and reinforcement to meet the needs of modern construction. [0003] Conventional reinforcement is mainly the method of anchor shotcrete, through the combination of newly added concrete and stressed steel bars and the original structure to form an integral composite structure of shotcrete (including reinforcing steel ...
