The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The all other embodiment obtained, shall fall within the protection scope of the present invention.
In the description of the present invention, it should be understood that term " trepanning ", "upper", "lower", " thickness ", "top",
" in ", " length ", "inner", indicating positions or the position relationship such as " surrounding ", be merely for convenience of description the utility model and simplification
Description, does not indicate or imply the indicated component or element must have a particular orientation, with specific azimuth configuration and behaviour
Make, therefore should not be understood as limiting the present invention.
As shown in Figure 1, the utility model provides a kind of high intensity bridge expanssion joint cover board, including fixed cover board 1 and
It is hinged on the removable cover 2 of 1 side of fixed cover board, 1 one end of fixed cover board is bolted on bridge expanssion joint side, another
End is equipped with waist-shaped hole 3, and removable cover 2 is inserted by rotation axis in waist-shaped hole 3 and fixed cover board 1 is hinged, is filled in waist-shaped hole 3
Elastic gel 4.
2 one end of removable cover is equipped with triangular hill 5, is provided with and 5 phase of triangular hill on the side wall of bridge expanssion joint side
The triangular groove 6 of adaptation when installation, by pressing removable cover 2, squeezes the elastic gel 4 in waist-shaped hole 3, rotation activity
The triangular hill 5 of removable cover 2 is directed at the triangular groove 6 on bridge expanssion joint side wall, is returned in elastic gel 4 by cover board 2
Under the action of elastic force, the triangular hill 5 of removable cover 2 is caught in the triangular groove 6 on bridge expanssion joint side wall, is solved
Existing bridge expanssion joint cover board cannot carry out good transition with the road surface of expansion joint both sides and connect, in use for some time
There is the phenomenon that alice, fold, effective protection bridge structure.It is same only to press work when needing to overhaul expansion joint
Dynamic cover board 2, squeezes the elastic gel 4 in waist-shaped hole 3, then raises removable cover 2, convenient for disassembly and assembly, greatly facilitates
The service work of bridge expanssion joint.
As shown in Fig. 2, removable cover 2 includes the cavity being made of curved roof 21, both sides side plate 22 and bottom plate 23,
It is equipped with buffer unit 25 filled with buffering sponge 24, cavity middle part in cavity, buffer unit 25 connects curved roof 21 and bottom plate
23, by buffering sponge 24 and buffer unit 25, avoid removable cover 2 by ambient pressure such as vehicle by when be seriously worn
And there is the case where the rupturing that fracture, extend the service life of bridge expanssion joint cover board.
As shown in Figure 3-4, buffer unit 25 includes the pressure block 7 being arranged below curved roof 21, and pressure block 7 is for passing
Pass the ambient pressure that curved roof 21 is subject to.Pressure block 7 connects the first buffer stopper 9 and the second buffer stopper 10 by rotation axis 8, the
One buffer stopper 9 is fixedly connected with rotation axis 8, and the second buffer stopper 10 is rotatablely connected with rotation axis 8,9 lower surface of the first buffer stopper and
Second buffer stopper, 10 upper surface is staggeredly equipped with plane ratchet 11,11 circle distribution of plane ratchet, the first buffer stopper 9 and second
Spring is equipped between buffer stopper 10.
It when the ambient pressure that curved roof 21 is subject to, is transmitted by pressure block 7, is pressed downward the first buffer stopper 9, first is slow
9 downward compressed spring of block is rushed, and is contacted with the second buffer stopper 10, by mutually being handed on the first buffer stopper 9 and the second buffer stopper 10
Downward pressure is decomposed into the rotatory force of circumferencial direction by the interaction between wrong plane ratchet 11, drives the second buffer stopper
10 rotate around rotation axis 8 so that the first buffer stopper 9 and the plane ratchet 11 on the second buffer stopper 10 are at a fully engaged, play buffering
Effect, when the ambient pressure that curved roof 21 is subject to disappears, the first buffer stopper 9 bounces under the action of recoil of spring power, the
Two buffer stoppers 10 turn round, and the recovery of plane ratchet 11 on the first buffer stopper 9 and the second buffer stopper 10 is staggered.
High intensity bridge expanssion joint cover board provided by the utility model, by the way that the fixation cover board being hinged and activity is arranged
Cover board is fixed by fixed cover board, only need to raise the service work that bridge expanssion joint can be completed in removable cover, dismounting side
Just, the working efficiency of bridge expanssion joint service work is substantially increased；By the way that protrusion is arranged in removable cover one end, stretched in bridge
Groove is arranged in contracting seam side wall, and removable cover end is caught in bridge expanssion joint side wall, solves existing bridge expanssion joint lid
Plate cannot carry out good transition with the road surface of expansion joint both sides and connect, and occur alice in use for some time, fold shows
As；By the way that buffering sponge and buffer unit are arranged in removable cover, removable cover is avoided to be passed through by ambient pressure such as vehicle
When be seriously worn and occur fractureing rupture the case where, extend the service life of bridge expanssion joint cover board, meet making for market
Use demand.
