Description

Technical Field

[0001] The utility model relates to the technical field of highway bridge construction, in particular to an earthquake-resistant steel structure of a highway bridge. Background Art

[0002] When building a highway bridge, it is necessary to build water supply and drainage pipes together for the drainage of the bridge road surface. Passing the water supply and drainage pipes under the bridge can ensure the integrity of the bridge structure while ensuring the smooth flow of the water supply and drainage pipes. Before starting to build the water supply and drainage pipes, it is necessary to install a supporting structure on the highway bridge to ensure the stability of the bridge. The supporting structure is made of materials such as concrete and steel supporting structure. After the support structure is installed, the pipe bracket is installed, and the water supply and drainage pipes are laid using the pipe bracket.

[0003] However, when erecting steel support structures on current highway bridges, earthquake-resistant steel structures are used in order to improve the earthquake resistance of highway bridges. However, there is no earthquake-resistant structure when connecting the pipeline support and the support structure, which means that the pipeline installation structure cannot play an earthquake-resistant role when the highway bridge vibrates. During long-term use, the installation structure will become loose due to the vibration of the bridge, which will affect the stability of the pipeline during long-term use. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a seismic steel structure of a highway bridge includes a vertical seismic structure 1 and an oblique seismic structure 2 arranged relatively thereto, wherein the vertical seismic structure 1 includes a vertical steel 6, a straight rod 8 is slidably provided inside the vertical steel 6, a sliding cylinder is provided inside the vertical steel 6, the straight rod 8 is inserted into the sliding cylinder, the sliding cylinder is fixedly connected to the inner wall of the vertical steel 6, a seismic damping rod 7 is fixedly connected to the upper end of the straight rod 8, a connecting cylinder 3 is fixedly connected to the lower end of the straight rod 8, and a clamp 4 cooperating with a water supply and drainage pipe is provided at the lower end of the connecting cylinder 3.

[0026] Through the above structure, the clamp 4 can be installed on the pipeline. How to further achieve the seismic effect on the pipeline? The specific structure is as follows:

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the oblique seismic resistant structure 2 includes an oblique steel 11, on which the oblique steel 11 are provided with damping slide rails arranged relatively to each other, the damping slide rail located at the top is provided with an upper slide sleeve 12 sleeved on the oblique steel 11, and the damping slide rail located at the bottom is provided with a lower slide sleeve 15 sleeved on the oblique steel 11, and the upper slide sleeve 12 and the lower slide sleeve 15 are respectively fixed with an upper connecting plate 13 and a lower connecting plate 16 arranged relatively to each other, and the upper connecting plates 13 and the lower connecting plates 16 on both sides are respectively A concave connector 14 and a concave connector 2 17 are rotatably provided, and the concave connector 14 is connected to the steel support structure of the highway bridge by bolts, and the concave connector 14 and the concave connector 2 17 are rotatably connected to the upper connecting plate 13 and the lower connecting plate 16 by a damping shaft, and a middle sleeve plate 18 fixedly connected to the connecting tube 3 is fixedly connected between the concave connector 2 17 on both sides, and the middle sleeve plate 18 and the concave connector 2 17 and the connecting tube 3 are all welded.

[0028] Through the above structure, the impact of vibrations generated by highway bridges on pipelines can be buffered.

[0029] Embodiment 2

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, a connecting hole 5 is provided in the connecting tube 3, and the straight rod 8 is threadedly connected to the connecting hole 5. The vertical steel 6 is fixedly connected with relatively arranged fixing blocks 9, and the fixing blocks 9 are threadedly connected with fastening bolts 10 that cooperate with the straight rod 8.

[0031] Through the above structure, the vertical seismic resistant structure 1 can be disassembled and separated separately, and the friction between the fastening bolts 10 and the straight rod 8 can be adjusted, thereby hindering the movement of the straight rod 8 to varying degrees.

[0032] During the specific implementation of the utility model, when it is necessary to lay water supply and drainage pipes on a highway bridge, after the steel support structure of the highway bridge is erected, an installation structure for laying water supply and drainage pipes is installed thereon. Specifically, the concave connectors on both sides are threadedly connected to the steel support structure using bolts, and the inclination degrees of the oblique seismic structures on both sides are the same. At this time, the vertical seismic structure is in a vertical state, and the upper end of the seismic damping rod is connected to the steel support mechanism. The middle sleeve can move vertically up and down, and finally the pipe is passed through the clamp, and the clamp is used to clamp the pipe, and the installation is completed;

[0033] During use, when the highway bridge vibrates, the middle sleeve moves up and down, the seismic damping rod will extend and retract, and the upper sliding sleeve and the lower sliding sleeve will slide along their respective damping slide rails. The damping slide rails can buffer the sliding cylinders of the upper sliding sleeve and the lower sliding sleeve. When used in conjunction with the seismic damping rod, the up and down movement of the middle sleeve can be buffered, that is, the impact of the vibration of the highway bridge on the pipeline can be buffered, thereby preventing the water supply and drainage pipeline from loosening due to the vibration of the highway bridge during long-term use.
