Description

Technical Field

[0001] The utility model belongs to the technical field of arch bridge structures, and particularly relates to a connection structure for an arch ring joint transition section in a hybrid arch bridge. Background Art

[0002] In a hybrid arch bridge, the steel-concrete combined part connects steel and concrete into one body, which is a key part of the hybrid system bridge. Due to the different material properties of steel and concrete, such as stiffness, strength, thermal expansion coefficient, etc., local stress concentration and insufficient bearing capacity are likely to occur at the connection part. Therefore, a reasonable design of the connection structure of the arch ring joint transition section is crucial for ensuring the overall performance and safety of the hybrid arch bridge. However, in the prior art, the connection structure of the arch ring joint transition section is all cast by reinforced concrete, resulting in slow manual work efficiency.

[0003] The patent application number "CN201821902153.5" discloses "an industrialized rapid construction reinforced earth arch bridge, which comprises a concrete foundation, a prefabricated assembled arch ring, a panel, reinforcing materials, backfill and a bridge deck. A clamping groove is left at the top end of the concrete foundation, and both ends of the prefabricated assembled arch ring are clamped in the clamping groove. Reinforcing bar joints are pre-buried on the prefabricated assembled arch ring, and reinforcing bars are connected to the pre-buried reinforcing bar joints on the prefabricated assembled arch ring. The panel is located on both sides of the prefabricated assembled arch ring, and the bridge deck is located above the prefabricated assembled arch ring. Backfill is filled between the bridge deck, the prefabricated assembled arch ring and the panel. It can be widely applied to the rapid construction of arch bridges in municipal engineering and highway engineering."

[0004] Based on the industrialized rapid construction reinforced earth arch bridge, the above patent cancels the support and formwork, adopts industrial production, and performs on-site sliding construction and installation, without complex connections, and the construction is simple. This structure adopts the reinforced earth technology, effectively reducing the soil load, making the structure lighter, the structure connection simpler, facilitating rapid assembly construction, reducing the risk of bump at bridgeheads, saving project investment, and improving the operation comfort.

[0005] The above patent replaces the traditional design and construction method through the sliding assembly construction of the industrialized reinforced earth arch bridge structure, which will improve the construction quality of the concrete structure, effectively solve the problem of bump at bridgeheads, shorten the on-site construction period, reduce the project cost, and beautify the appearance of the arch bridge. However, for the connection structure of the arch ring joint transition section, the above device only performs casting and fixing after sliding connection, resulting in poor connection stability of the arch ring joint transition section. For subsequent casting operations, if the arch ring joint transition section slips, manual assistance is required for fixing, which increases the labor intensity of workers and the connection structure of the arch ring joint transition section is also unstable. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a connecting structure for the transition section of the arch ring joint in a hybrid arch bridge, aiming to solve the problem in the prior art that for subsequent pouring operations, if the arch ring joint transition section slips, manual assistance is still required for fixing, which increases the labor intensity of workers, and the connecting structure of the arch ring joint transition section is also unstable.
