Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bridge construction, and particularly relates to a bridge anti-collision structure with good flame retardancy. Background Technique
[0002] A bridge refers to a structure built to connect two objects and span rivers, valleys or other obstacles. It can be a spanning structure for railways, roads, channels or pipelines, or a structure for vehicles, pedestrians, etc. to pass through. During the construction of a bridge, the pier is an extremely important part. Its main function is to support the bridge span structure and ensure the stability and safety of the bridge. The pier is also the position most easily scratched and impacted by passing ships. When the pier is impacted, it will not only affect the overall stable structure, but also, after the ship impacts, a fire is likely to occur. The high temperature generated during combustion will cause the steel bars inside the pier to soften, resulting in unstable structure and affected force.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] Please refer to Figures 1-4, the present utility model provides a technical solution: a bridge anti-collision structure with good flame retardancy, comprising: a bridge deck 1, both left and right sides of the lower surface of the bridge deck 1 are connected with columns 2, the outer sides of the columns 2 are provided with B-type composite anti-collision fenders 3 in an array, the outer surface of the front side of the column 2 is sleeved with an A-type composite anti-collision fender 4, the lower surface of the column 2 is connected with a bridge pier 5, the inside of the bridge pier 5 is connected with connecting ribs 6 in an array, the lower ends of the connecting ribs 6 extend into the riverbed, the A-type composite anti-collision fender 4 includes an outer shell 41, the outer shell 41 is made of plastic material, the inside of the outer shell 41 is provided with A-type buffer energy dissipation elements 42 in a circular array, the outside of the A-type buffer energy dissipation elements 42 is wrapped with fiberglass cloth, and fireproof cotton is filled between the A-type buffer energy dissipation elements 42 and the outer shell 41; the B-type composite anti-collision fender 3 includes an outer shell two 31, the inside of the outer shell two 31 also places the A-type buffer energy dissipation elements 42, a B-type buffer energy dissipation element 32 is placed in the middle of the inside of the outer shell two 31, the B-type buffer energy dissipation element 32 is also wrapped with fiberglass cloth, and fireproof cotton is filled between the inside of the outer shell two 31 and the A-type buffer energy dissipation elements 42 and the B-type buffer energy dissipation element 32; square steel frames 7 are connected in an array inside the B-type composite anti-collision fender 3 and the A-type composite anti-collision fender 4, a steel belt 8 is sleeved outside the square steel frames 7, and the steel belt 8 and the column 2 are connected by bolts.
[0025] In use, after the pier 5 is built, the column 2 is built, and finally the bridge deck 1 is installed. After completion, layout and positioning are carried out on the outer surface of the column 2. After completion, avoid the steel bars inside the column 2 and drill holes. After the holes reach the required aperture and depth, the surface of the column 2 is polished flat, and the holes are cleaned with a blower and a steel brush. Then, the planting glue and the screw are inserted into the holes for fixation. After the planting glue reaches the required strength, the B-type composite anti-collision fender 3 is attached to the outer surface of the column 2. Then, the steel belt 8 is sleeved on the outside of the square steel frame 7. Then, the holes on the left and right sides of the steel belt 8 are sleeved on the outside of the screw, and then fixed and connected through nuts. After installation, the A-type composite anti-collision fender 4 is sleeved on the front side of the column 2 on the side opposite to the water flow.

When a collision occurs, the hull will hit the outside of the A-type composite anti-collision fender 4 and the B-type composite anti-collision fender 3. At this time, the impact force will impact on the A-type buffer energy-consuming element 42 and the B-type buffer energy-consuming element 32. The base grease of the A-type buffer energy-consuming element 42 and the B-type buffer energy-consuming element 32 is vinyl resin, polyurethane resin, epoxy resin, unsaturated resin, etc. After absorbing part of the impact force, it is then conducted to the column 2 to reduce the impact force. When a fire occurs, after the outer shell is burned off, the fireproof cotton and fiberglass cloth filled inside can play a role in fire prevention and heat insulation, while helping combustion and reducing the transfer of temperature.
