Detailed Implementation

[0019] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-4 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0020] See Figure 1-4A precast steel bridge pier includes a pier body 1 and a support frame 2 fixed to the top of the pier body 1. The pier body 1 includes a plurality of pier blocks 11 fixed from top to bottom. The support frame 2 includes a connecting body 21 symmetrically fixed to the top of the uppermost pier block 11 and support columns 22 symmetrically fixed to both sides of the top of the connecting body 21 and gradually inclined outward from bottom to top. The outer diameter of each support column 22 gradually decreases from bottom to top. A support plate 23 is fixed to the top of each support column 22. At least one mounting block 24 is installed on the top of each support plate 23. A plurality of inclined first reinforcing blocks 25 are fixed parallel to each other on the outer side wall of the top of each support column 22. The top of each first reinforcing block 25 is fixedly connected to the bottom of the support plate 23.

[0021] The precast steel bridge piers of this invention can significantly shorten the construction cycle and reduce construction costs by adopting a modular design. At the same time, it can reduce the amount of on-site work, shorten the time that construction workers are exposed to dangerous environments, and reduce safety risks.

[0022] In this embodiment, each support column 22 includes at least two support blocks 26 fixed sequentially from top to bottom, and multiple first reinforcing blocks 25 are fixed to the outer side wall of the top of the uppermost support block 26. By configuring the support column 22 as multiple support blocks 26, the support blocks 26 can be prefabricated in the factory, reducing on-site construction time and complexity, and facilitating transportation.

[0023] In this embodiment, a fixing block 27 is fixed between the bottoms of the two support columns 22. By setting the fixing block 27, the two support columns 22 can be firmly fixed together, preventing the support columns 22 from collapsing due to insecure fixing to the connecting body 21, and enhancing the stability of the support frame 2.

[0024] In this embodiment, the connecting body 21 includes two symmetrically fixed connecting blocks 28. The tops of the two connecting blocks 28 are each provided with outwardly inclined slopes (not shown in the figure). The bottoms of the two support columns 22 are respectively fixed to the inclined slopes at the top of the corresponding connecting blocks 28. By setting the inclined slopes to be fixedly connected to the support columns 22, the force of the support columns 22 can be concentrated and transmitted to the connecting body 21, effectively dispersing and transferring the load, avoiding local stress concentration, and thus improving the load-bearing capacity and stability of the entire support frame 2.

[0025] In this embodiment, a base plate 3 is fixed to the bottom of the pier body 1, and multiple second reinforcing blocks 31 are welded in a circular array on the outer side wall of the bottom of the pier body 1. The bottom of each second reinforcing block 31 is fixedly connected to the top of the base plate 3. By setting the second reinforcing blocks 31, the stability of the connection between the pier body 1 and the base plate 3 can be strengthened, and the pier body 1 can be effectively prevented from tilting.

[0026] In this embodiment, the top of the base plate 3 has multiple fixing holes 32 corresponding to the outer side of the pier body 1. By setting the fixing holes 32, the pier can be firmly fixed to the ground with steel bars to prevent the pier from tilting.

[0027] In this embodiment, the pier body 1 is a hollow structure, and a connecting plate 4 is fixed to the top of the pier body 1. The top of the connecting plate 4 is fixedly connected to the bottom of the support frame 2. Since the pier body 1 is a hollow structure, the connecting plate 4 facilitates the fixing between the pier body 1 and the support frame 2.

[0028] In this embodiment, the included angle between the two support columns is 50-60°. In this embodiment, the load-bearing effect of the support frame is best when the included angle between the two support columns is 55°.

[0029] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
