[0002] An overpass is an overhead bridge built for pedestrians to safely cross the road. A steel structure overpass refers to an overpass mainly built with steel as the main building material. Steel has the characteristics of high strength, good toughness, easy processing and installation, etc., enabling the steel structure overpass to bear a large load and having good stability and durability.

[0003] The steel structure overpass usually spans above the street or highway, connecting the sidewalks on both sides of the road, enabling pedestrians to pass through the road safely without mixing with vehicles. The steel structure overpass helps to reduce the conflicts between pedestrians and vehicles, improve traffic efficiency, ensure the safety of pedestrians' lives, and also relieve the road traffic congestion to a certain extent.

[0004] However, when the existing steel structure overpass is built, it is not conducive to positioning the steel structure overpass, and it is not possible to conveniently position the steel structure overpass, which will affect the work efficiency of building the steel structure overpass and is not conducive to building the steel structure overpass.

The positioning of the steel structure overpass main body 1 and the support columns 6 is facilitated by the positioning blocks 11 and the positioning grooves 12 and the limiting blocks 13 and the limiting grooves 14. When the steel structure overpass main body 1 is erected during use, the positioning of the steel structure overpass main body 1 is facilitated, the positioning of the steel structure overpass main body 1 can be conveniently carried out, so as to ensure the working efficiency of erecting the steel structure overpass main body 1, and the erection of the steel structure overpass main body 1 is facilitated.

[0034] Among them, the support columns 6 are all in a vertical state. Second mounting rings 8 are fixed at the lower ends of the outer circumferential surfaces of the support columns 6. Second bolts 10 are vertically threadedly inserted in the middle parts around the second mounting rings 8. The second bolts 10 are all in a vertical state. The second bolts 10 are helpful for the installation and limitation of the second mounting rings 8. The second bolts 10 all penetrate the upper surface and the lower surface of the corresponding positions on the corresponding second mounting rings 8. A plurality of first bolts 9 are vertically threadedly inserted at intervals along the circumferential direction on the first mounting rings 7. The first bolts 9 are all in a vertical state. The first mounting rings 7 are helpful for the limitation of the first bolts 9.

[0035] The first bolts 9 all penetrate through the upper and lower surfaces at corresponding positions on the corresponding first mounting rings 7. The upper ends of the first bolts 9 are all threadedly inserted into the corresponding positions on the steel structure overpass main body 1. The first bolts 9 can install the first mounting rings 7 and the steel structure overpass main body 1; the steel structure overpass main body 1 is in a horizontal state. At the middle of both ends of the upper surface of the steel structure overpass main body 1, connection blocks 15 are fixedly installed. The connection blocks 15 are all in a vertical state.

The ladder 2 can fix and limit the third guardrails 5, facilitating the stable use of the third guardrails 5.

[0037] The working principle of the present utility model is: during use, the lower surface of the support column 6 is corresponded to the position where installation is required outside, so that the lower surface of the second mounting ring 8 corresponds to the position where installation is required outside. Further, the second bolts 10 are used to install between the second mounting ring 8 and the position where installation is required outside. The second bolts 10 can fix and limit the second mounting ring 8, facilitating the stable use of the second mounting ring 8.
