Description

Technical Field

[0001] This utility model relates to the technical field of long-span continuous beam structures, specifically a long-span continuous beam structure for bridge joints. Background Technology

[0002] A design called a continuous beam is frequently seen in common bridge and building structures. It can span tens or even hundreds of meters, making it the preferred solution for various large-span buildings. The joints of large-span continuous beam bridges mainly refer to the expansion joint area and the ends of adjacent beams.

[0003] Existing large-span continuous beam structures at bridge joints cannot actively and quickly drain leaking water during use, leading to water accumulation at critical locations such as beam ends, supports, and cap beams. This significantly increases the risk of freeze-thaw and salt-freeze corrosion caused by water seepage. Therefore, there is an urgent need for a new type of large-span continuous beam structure at bridge joints to solve these technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a large-span continuous beam structure for bridge joints, in order to solve the problem mentioned in the background art that the existing large-span continuous beam structures for bridge joints cannot actively and quickly drain leaking water during use, resulting in accumulation at key parts such as beam ends, supports, and cap beams, which significantly increases the problems of freeze-thaw and salt-freeze corrosion caused by water seepage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A long-span continuous beam structure at a bridge joint includes double-walled piers. The bottom of the double-walled piers is provided with a reinforced concrete base. A lower crossbeam is connected to the side wall of the double-walled piers. Diagonal braces connect the double-walled piers and the lower crossbeams. A long longitudinal beam is connected to the top of the lower crossbeam. A supporting top beam is connected to the top of the long longitudinal beam. Support blocks are connected to both sides of the top of the supporting top beam. A flow-guiding rubber block is connected to the upper side of the front end face of the supporting top beam. A flow-guiding groove is formed on the top of the flow-guiding rubber block, and the flow-guiding groove is inclined.

[0007] As a preferred technical solution of this utility model, the number of the lower crossbeams is set to two, and the two lower crossbeams are arranged symmetrically about the reinforced concrete base.

[0008] As a preferred embodiment of this utility model, the two supporting blocks are arranged symmetrically about the supporting top beam.

[0009] As a preferred embodiment of this utility model, the cross-sectional shape of the support block is a right-angled triangle structure.

[0010] In a preferred embodiment of this invention, the diagonal brace is inclined.
