Description

Technical Field

[0001] The utility model relates to the technical field of bridge construction, in particular to a parallel connection device for a column-type bracket of a curved box girder bridge. Background Art

[0002] With the rapid development of my country's urban modernization and high-grade highway transportation infrastructure, curved beam bridges have been widely used and developed, especially in urban grade separations and expressways, where curve line shape control is almost indispensable. Due to the limitations of terrain and environment, the construction of grade separations and viaducts in busy urban areas requires the axial direction of the bridge to obey the requirements of the line and to be curved in the plane to provide smooth driving conditions. In the construction of high-grade highways, due to the overall line selection needs, or limited by terrain and landforms, curved beam bridges are also needed in many cases to meet the requirements of traffic operations.

[0003] The beam-column support is an indispensable part in the construction of curved box girder bridges. It is used to provide fixed support for curved box girder bridges and plays a very important role in curved beam bridges. In order to ensure the safety of curved beam bridges during use, it is necessary to improve the stability of the beam-column support for the fixed support of the curved beam bridge.

[0004] Therefore, how to provide a flat coupling device for a curved box girder bridge column support has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by the utility model is how to provide a parallel connection device for a curved box girder bridge column bracket.

[0006] To achieve the above-mentioned purpose, the utility model provides a parallel connection device for a column-type support of a curved box girder bridge, comprising: a support, wherein two groups of the supports are symmetrically arranged at equal intervals, and an installation space is formed between adjacent supports, a parallel connection mechanism is arranged in the installation space, and the parallel connection mechanism is a parallel connection piece a and a parallel connection piece b, and the parallel connection piece a and the parallel connection piece b have different lengths and the same width.

[0007] The design of the parallel joint mechanism improves the fixed support effect of the bracket on the curved box girder bridge to a certain extent. The parallel joints a and b with different lengths and the same width form parallel joint mechanisms of two sizes, which can be used alone or in combination according to specific construction requirements.

[0008] Preferably, the support is a steel pipe pile with a diameter of 630*10.

[0009] The advantages of steel pipe piles mainly include high strength, corrosion resistance, long service life, simple structure, convenient use, good sealing, good elasticity, strong bearing capacity, easy adjustment of pile length, and slight soil extrusion.

[0010] High strength, corrosion resistance and long service life: Steel pipe piles are widely used in various engineering projects due to their high strength and corrosion resistance, ensuring their long-term and stable service life.

[0011] Simple structure, easy to use, and good sealing: Steel pipe piles are composed of steel pipes, tongue and groove mortise and tenon pins. They have a simple structure and are easy to use. They have good sealing and are suitable for a variety of engineering scenarios.

[0012] Good elasticity: Steel pipe piles have good elasticity and can adapt to different geological conditions, reducing damage caused by foundation deformation.

[0013] Strong bearing capacity: Steel pipe piles are mostly made of low-carbon steel, with high tensile, compressive and bending resistance, and are suitable for use in geological environments with strong bearing layers.

[0014] Easy to adjust the pile length: The conventional length of each section of steel pipe pile is 6 meters, which can be extended by welding, so it is easy to adjust according to the burial depth of the bearing layer and improve economic benefits.

[0015] Slight soil extrusion: Most steel pipe piles adopt an open design with thinner pipe walls, which reduces the uplift of the topsoil and extruded soil and reduces interference with the soil and surrounding facilities.

[0016] Preferably, a base is provided on the lower end surface of the bracket, and the bracket and the base are fixedly connected.

[0017] The design of the base cooperates with the bracket to provide fixed support for the curved box girder bridge. The fixed connection design not only ensures the stability of the connection between the bracket and the base, but also further ensures the stability of the fixed support for the curved box girder bridge.

[0018] Preferably, a connector for connecting with the parallel connection mechanism is provided in the installation space of the bracket, and the parallel connection mechanism and the bracket form a detachable structure via the connector.

[0019] The detachable structure not only ensures the stability of the installation of the parallel connection mechanism, but also makes it convenient for the staff to replace or maintain the parallel connection mechanism at a later time, which reflects the practicality of the device.

[0020] Preferably, the parallel connecting member a and the parallel connecting member b are both composed of two cross beams and two side beams, and diamond-shaped reinforcement members are arranged between the two cross beams and the two side beams.

[0021] This design is used to install the reinforcement member, and the design of the reinforcement member ensures the leveling effect of the leveling member a and the leveling member b on the brackets.

[0022] Preferably, more than one group of the parallel joints a or parallel joints b are arranged in the installation space of the bracket, and each group is provided with more than one parallel joint a or parallel joint b, and adjacent parallel joints a or parallel joints b are connected via Bailey sheets to form a detachable structure.

[0023] This design makes it easy to select and install a corresponding number of parallel joints a and parallel joints b according to actual construction needs, so that the device is suitable for different construction sites and avoids limitations during use.

[0024] The beneficial effects of the utility model are:

[0025] When the utility model is in use, the design of the leveling mechanism improves the fixed supporting effect of the bracket on the curved box girder bridge to a certain extent, and the leveling parts a and the leveling parts b with different lengths and the same width form leveling mechanisms of two sizes respectively, which can be used alone or in combination according to specific construction requirements, avoiding limitations in use, reflecting the practicality of the device, and thus facilitating popularization and use.
