Description

Technical Field

[0001] The present application relates to the field of municipal construction technology, and in particular to a steel temporary bridge assembly. Background Art

[0002] Due to the needs of municipal construction, the construction shafts of dark-excavated tunnels often occupy urban roads. In order to ensure construction safety and reduce environmental impact, it is necessary to build a closed canopy above the shaft, and the shaft is constructed inside the canopy. To avoid traffic being affected, the width of the road that the shaft canopy can occupy is usually limited. At this time, if the width of the shaft exceeds the width of the road allowed to be occupied, part of the shaft will be located outside the canopy. In order to meet the traffic needs and construction safety, it is necessary to lay a temporary bridge above the shaft outside the canopy to ensure traffic above and meet the construction conditions below. The steel temporary bridge is a temporary supporting bridge built at the construction site or a bridge built temporarily during road construction. It can be dismantled when it is not needed.

[0003] The patent document with the published announcement number CN219951655U provides a steel bridge assembly, including multiple steel bridge units, multiple steel bridge units with the same size parameters, multiple steel bridge units laid on both sides of the shaft opening, or multiple steel bridge units laid on the shaft opening; the steel bridge unit includes a main beam, a secondary beam and a bridge deck. The steel bridge assembly of the utility model has the advantages of good versatility, safety and reliability, and can be applied to different types of shafts.

[0004] Most of the steel temporary bridges in the above application documents are built rather casually. Since mechanical equipment such as drilling rigs, cranes and construction vehicles have a large deadweight, when these equipment pass through the steel temporary bridges, there is a large horizontal thrust on the steel temporary bridges, which can easily cause horizontal displacement of the steel temporary bridges. During use, the ends of the steel temporary bridges are prone to loosening, posing a safety hazard. Utility Model Content

[0012] As a preferred embodiment, the auxiliary fixing part includes a shuttle plate, a waist-shaped adjustment hole is opened in the middle of the shuttle plate, a first positioning bolt is passed through the waist-shaped adjustment hole, one end of the first positioning bolt is fixedly connected to the outer side of the beam bracket, and the other end is threadedly connected to a fixing nut, symmetrically distributed positioning holes are provided at both ends of the shuttle plate, a second positioning bolt is threaded in the positioning hole, a fixing screw hole compatible with the second positioning bolt is opened on the outer side of the beam bracket, and the lower end of the U-shaped clip is sleeved on the outer side of the second positioning bolt.

[0013] By adopting the above technical solution, the waist-shaped adjustment hole is responsible for adjusting the height of the shuttle plate on the outside of the support and making the positioning holes at both ends of the shuttle plate consistent with the fixing screw holes, and then the second positioning bolt is inserted into the positioning hole and the fixing screw hole in sequence, thereby fixing the shuttle plate to the outside of the support, thereby making the connection between the support and the crossbeam bracket more stable.

[0014] As a preferred embodiment, a first positioning cylinder is provided between the waist-shaped adjustment hole and the positioning hole, a second positioning cylinder is provided on the surface of the clamp, and a second connecting rod is fixedly installed between the first positioning cylinder and the second positioning cylinder.

[0015] By adopting the above technical solution and assembling the second connecting rod between the first positioning cylinder and the second positioning cylinder, the connection firmness between the clamp and the support is further enhanced.

[0016] As a preferred embodiment, a buffer rubber pad is provided on the inner wall of the assembly groove.

[0017] By adopting the above technical solution, the buffer rubber pad helps to alleviate the vibration of the bridge deck, thereby improving the seismic performance of the steel temporary bridge.

[0018] Beneficial effects of this application:

[0019] The steel temporary bridge assembly is provided with bridge piers, beam supports, seats and auxiliary fixings. First, the U-shaped clamp is hung on the beam support, and then the beam support is placed in the assembly groove on the top of the seat. Preliminary positioning is performed by the positioning protrusion and the positioning groove. The movable clamp further limits the positioning protrusion, which can prevent the beam support from horizontal displacement under the action of horizontal thrust, and can effectively reduce safety hazards. The waist-shaped adjustment hole is responsible for adjusting the height of the shuttle plate on the outside of the seat and making the positioning holes at both ends of the shuttle plate consistent with the fixing screw holes. Then the second positioning bolt is inserted into the positioning hole and the fixing screw hole in turn, thereby fixing the shuttle plate on the outside of the seat, thereby making the connection between the seat and the beam support more stable; the second connecting rod can further enhance the connection firmness between the clamp and the seat.
