Bridge wet joint reinforcing device and mounting method

Abstract

The invention discloses a bridge wet joint reinforcing device. The device comprises a contact steel plate, reinforcing steel plates and chemical anchor bolts; the two side faces of the contact steel plate are connected with a main beam web through the chemical anchor bolts; the top face of the contact steel plate is connected with a main beam flange plate and a wet joint through the chemical anchor bolts; the inclined face of the contact steel plate is connected with a main beam bearing; the reinforcing steel plates are fixed to the contact steel plate so as to form parallel T-shaped beams. According to the device and mounting method of the invention, symmetrical bolt holes are distributed in the contact steel plate; the contact steel plate is connected with a leveled main beam through thechemical anchor bolts; the contact steel plate and the reinforcing steel plates are connected through fillet welds; the multiple sets of reinforcing steel plates and the contact steel plate form parallel T-shaped beams; and such a structure can effectively improve the bearing capacity of the wet joint of a bridge, reinforce the transverse connection of the bridge and improve the integrity of thebridge, and has the advantages of environmentally friendly and rapid construction, wide applicability and good economical efficiency.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a bridge reinforcement device, more specifically to a bridge wet joint reinforcement device and an installation method. Background technique [0002] Prefabricated simply supported concrete bridges are widely used in bridge construction in my country because of their reasonable stress, simple structure, fast construction, and investment savings, especially prefabricated small box girders, T-shaped girders, and hollow slab girders. Among them, the horizontal connection between the prefabricated concrete small box girder and the main girder is realized through longitudinal cast-in-place wet joints, and then the overall mechanical performance of the bridge structure is strengthened by means of the integrated layer and bridge pavement. [0003] However, in recent years, due to the continuous increase in traffic volume and the long-term action of heavy-duty vehicles, proble...

Problems solved by technology

[0004] At present, when the wet joint is seriously damaged, it needs to be removed and re-cast, but the newly poured wet joint may have the same problem again after a period of use. Therefore, it is necessary to provide a wet joint reinforcement device for Wet seams are reinforced to improve wet seam performance
