Description

Technical Field

[0001] This utility model relates to the field of bridge cantilever construction technology, specifically to a bridge support for cantilever construction. Background Technology

[0002] In modern bridge construction, cantilever construction is a commonly used technique, especially suitable for bridges spanning complex terrains such as rivers, canyons, or major transportation routes. As a key piece of equipment in this construction method, the stability and adjustability of the cantilever bridge support are crucial for ensuring construction quality and safety.

[0003] However, in the actual construction process, some challenges are often encountered. First, before the cantilever bridge support is installed, its bottom surface needs to be leveled to ensure the stability and load-bearing capacity of the support. However, the soil conditions at the construction site are often complex and changeable, and settlement is prone to occur. Soil settlement is a gradual process that may occur in the early stage or during construction, which may damage the flatness of the bottom surface of the support.

[0004] Therefore, a cantilever bridge support system is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a cantilever bridge support in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A cantilever bridge support system includes a pier and a cantilever bridge on top of it. Multiple sets of standard support joints are installed on both sides of the pier via adjustable support bases. The position of the standard support joints is adjusted and adapted to soil settlement via four sets of adjustable support bases at the bottom of the lowest standard support joint. A support frame assembly is bolted to the top of the uppermost standard support joint and is fixed to the surface of the cantilever bridge. The adjustable support base includes a first connecting plate bolted to the connecting end of the lowermost standard support joint. A threaded rod is fixedly installed at the bottom of the first connecting plate. A threaded sleeve is threaded onto the surface of the threaded rod, and a second connecting plate is rotatably installed at the bottom of the threaded sleeve. The second connecting plate is fixed to the ground via anchor bolts.

[0008] Furthermore, a collar is fitted onto the surface fixing plate of the threaded sleeve rod, and a plug ring is fixedly installed on the surface of the threaded sleeve rod between the two sets of collar rings, so as to rotate the second connecting plate by operating the collar / plug ring with a tool.

[0009] Further, the support frame assembly comprises a connecting seat fixedly installed at the uppermost standard support joint connecting end by bolting, and two groups of inclined support frames are fixedly installed at the top end of the connecting seat and fixed to the surface of the cantilever bridge, and the bottom surface of the two groups of inclined support frames is fixedly installed with reinforcing ribs.

[0010] Further, the top surface of the inclined support frame is provided with a groove, and a support cross frame is fixedly installed in the groove.

[0011] Further, the adjacent standard support joints are connected by bolting.

[0012] The beneficial effects of the utility model are as follows:

[0013] By rotating the threaded sleeve rod, the extension length of the threaded rod can be adjusted, so that the height of the standard support joint can be flexibly adjusted. This design not only can adapt to the uneven settlement of soil, but also can ensure the stability and carrying capacity of the support, avoid the inclination or failure of the support caused by soil settlement, and ensure the construction safety.

[0014] By providing the threaded sleeve rod with a sleeve ring and a plug-in ring on the surface, the construction personnel can conveniently operate these components using tools, quickly rotate the threaded sleeve rod to adjust the height of the standard support joint. This convenient adjustment method greatly improves the construction efficiency, reduces the time and manpower consumed for adjusting the support, and has a significant advantage especially in the construction environment that needs to be frequently adjusted.
