Embodiment 1

[0018] Embodiment 1: When the expansion joint is used in a highway bridge, an expansion joint for highway bridge technical service includes a first bridge 1, a second bridge 2 and a gap 3, the right end of the first bridge 1 and the left end of the second bridge 2 are The slit 3 is the axis of symmetry and is respectively provided with a first trapezoidal surface 4 and a second trapezoidal surface 5 above the first trapezoidal surface 4. The upper surface of the first trapezoidal surface 4 is provided with three rolling axes 6, and the upper surface of the first trapezoidal surface 4 is Located on the outer side of the gap 3 is fixedly connected with a limit bolt 7 for preventing the rolling shaft 6 from slipping, and a water guide plate 8 is arranged between the gap 3, and the top of the water guide plate 8 is fixedly connected with the limit bolt 7 by bolts, and the rolling shaft 6 A bracket 9 is arranged on the top, between the left side wall of the bracket 9 and the first b...

Embodiment 2

[0021] Embodiment 2: when not in use, an expansion joint for highway bridge technical service, including a first bridge 1, a second bridge 2 and a gap 3, the right end of the first bridge 1 and the left end of the second bridge 2 take the gap 3 as the axis of symmetry respectively A first trapezoidal surface 4 and a second trapezoidal surface 5 located above the first trapezoidal surface 4 are provided. Three rolling shafts 6 are arranged on the upper surface of the first trapezoidal surface 4. The upper surface of the first trapezoidal surface 4 is located outside the gap 3 and its position is fixed. A limit bolt 7 for preventing the rolling shaft 6 from slipping is connected, a water guide plate 8 is arranged between the gaps 3, the tops of the water guide plate 8 are fixedly connected with the limit bolt 7 by bolts, and a bracket 9 is arranged above the rolling shaft 6 , between the left side wall of the bracket 9 and the first bridge 1, between the right side wall of the br...

Abstract

The invention relates to the field of technical services, in particular to an expansion joint for highway bridge technical services. Fixed seats are fixedly connected to the left and right ends of theupper surface of a bracket; a supporting block is fixedly connected to the middle part of the upper surface of the bracket; a locating seat is fixedly connected to a second trapezoidal surface; limiting plates, which are crossed in a comb tooth shape in parallel, are fixedly connected to the upper surface of the locating seat; a plurality of fixed plates positioned between the crossed limiting plates of a first bridge and a second bridge are arranged on the upper surface of the supporting block; and a water guide plate is made of a rubber material. The expansion joint for the highway bridge technical services has the advantages that a discontinuous maintenance function of the expansion joint can be realized to provide great convenience for operation of related working personnel by arranging the devices such as the limiting plates, the fixed plates, the bracket and so on; and meanwhile, as the gap of the expansion joint is small and the vibration generated during the passing of the vehicle is small, the passing safety of the vehicle is greatly enhanced and the service life of the bridge is greatly prolonged.

Description

technical field [0001] The invention relates to the technical service field, in particular to an expansion joint for highway bridge technical service. Background technique [0002] The bridge expansion joint is a device set in the gap formed between two adjacent girders in order to meet the deformation requirements of the bridge deck. The girder body can be the main girder section, or an abutment connected with the main girder. Bridge expansion joints are required to be free to expand and contract in both directions of the length and width of the bridge, and to be firm and reliable. Vehicles should run smoothly, without sudden jumps and noises, and should be able to prevent rainwater, garbage and soil from infiltrating and blocking. It can be seen that bridge expansion joints play an important role in the expansion, waterproofing and drainage performance of the beam end, and its quality and performance will directly affect the durability of the entire bridge.
