Description

Expansion joint structure of bridge

Technical Field

The utility model relates to an expansion joint structure of bridge belongs to road and bridge technical field.

Background

Bridge expansion joints are an important structure of bridges. The expansion joint of the bridge is designed to meet the requirement of deformation of the bridge deck, and is usually arranged between two beam ends, between the beam ends and a bridge abutment or at the hinged position of the bridge, and can meet the deformation of the bridge when stressed or expanded with heat and contracted with cold.

Therefore, the expansion joint is required to be capable of freely expanding and contracting in two directions parallel to and perpendicular to the axis of the bridge, and is firm and reliable, and a vehicle is required to be stable when running without sudden jump, jolt and noise. At present, common bridge expansion joints have poor shock resistance, the requirement of large displacement is difficult to meet, and after the common bridge expansion joints are used for a period of time, vehicles can generate large jolts and vibration sounds due to impact when passing.

SUMMERY OF THE UTILITY MODEL

The utility model discloses a solve and exist not enoughly among the prior art, provide one kind and can guarantee that the vehicle traveles steadily, go the expansion joint structure of the strong bridge of impact property.

The utility model discloses a realize through following technical scheme:

the utility model provides an expansion joint structure of bridge promptly, including first boundary beam, second boundary beam and rubber seal strip, first boundary beam and second boundary beam are C type boundary beam, rubber seal strip installs between the notch of first boundary beam and second boundary beam, respectively be equipped with a cellular shock attenuation body on the lower terminal surface of first boundary beam and second boundary beam, a plurality of honeycomb holes have been seted up to the internal portion of cellular shock attenuation body, the lateral surface lower extreme of first boundary beam is an inclined plane, evenly distributed has a plurality of rubber buffering bodies on this inclined plane, two bar holes have been seted up to the internal portion of rubber buffering, respectively fixedly on the lateral surface of first boundary beam and second boundary beam be equipped with a plurality of anchor muscle, a plurality of anchor muscle are evenly set up on the lateral surface of two boundary beams.

The utility model discloses be equipped with cellular shock attenuation body at the lower extreme of boundary beam, be equipped with the rubber buffering body on the side of one of them boundary beam, shock resistance is strong, can satisfy the requirement of large displacement volume, and the vehicle goes more steadily, no kick jolts and the noise above that.

Further preferably, two cellular shock absorbers lower extreme is equipped with a base, avoids the direct and road bed contact of cellular shock absorbers, is favorable to guaranteeing the shock attenuation effect and the life of cellular shock absorbers.

Further preferably, the outer end of the upper portion of the anchoring rib is welded with a first embedded steel bar in an L shape, the lower end of the anchoring rib is welded with a second embedded steel bar, and the second embedded steel bar is vertically arranged. In the installation the utility model discloses the time, at first will through embedded bar the utility model discloses install on the road bed, then at the bridge floor of mating formation, simple to operate is difficult for appearing the deviation.

Compared with the prior art, the utility model discloses the beneficial effect who has is:

Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 2, an expansion joint structure of a bridge comprises a first boundary beam 1, a second boundary beam 2 and a rubber sealing strip 3, wherein the first boundary beam 1 and the second boundary beam 2 are C-shaped boundary beams, the rubber sealing strip 3 is installed between notches of the first boundary beam 1 and the second boundary beam 2, a honeycomb-shaped damping body 6 is respectively arranged on the lower end surfaces of the first boundary beam 1 and the second boundary beam 2, a base 5 is arranged at the lower end of each of the two honeycomb-shaped damping bodies 6, a plurality of honeycomb holes 7 are arranged inside each of the honeycomb-shaped damping bodies 6, the lower end of the outer side surface of the first boundary beam 1 is an inclined surface, a plurality of rubber buffer bodies 8 are uniformly distributed on the inclined surface, two strip-shaped holes 9 are arranged inside each of the rubber buffer body 8, a plurality of anchoring ribs 10 are respectively fixedly arranged on the outer side surfaces of the first boundary beam 1 and the second boundary beam 2, the plurality of anchoring ribs 10 are uniformly arranged on the outer side surfaces of the two boundary beams, an L-shaped embedded steel bar 11 is welded on the outer end, the lower extreme welding of anchor muscle 10 is equipped with two 4 of embedded bar, and two 4 vertical settings of embedded bar.

The working process is as follows:

will the utility model discloses when installing on the bridge floor, install embedded bar in the road bed earlier, then at the outside pitch of mating formation of two boundary beams again, the installation is more reliable, more accurate, and two cellular shock absorbers 6 play fore-and-aft shock attenuation and skew effect, and rubber buffer body 8 plays the horizontal impact force and the skew that produces of buffering vehicle, and rubber buffer body 8 sets up the one side that the vehicle went to because only this direction is the one side that has the impact force.

In the description of the present invention, the terms "inside", "outside", "upper", "lower", "top", "bottom", and the like indicate the directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for convenience of description of the present invention and do not require the present invention to be constructed and operated in a specific direction, and thus, should not be construed as limiting the present invention.
