The block piece of elasticity can be with the progress flexible deformation that becomes larger or become smaller of bridge expanssion joint, and therefore, this structure is better able to adapt to
The demand of bridge expanssion joint.
As a kind of improvement embodiment of flexible block piece 6,6 cross section of the flexibility block piece is U-shaped, the flexibility block piece
It can be under the drive of the corresponding water conservancy diversion arm 5 closer or far from and two of the flexible block piece 6 between 6 two side walls
Side wall is fixedly connected respectively with the corresponding water conservancy diversion arm 5, and U-shaped flexible block piece 6 tool is there are two upright side wall, in same water conservancy diversion
During arm 5 is fixed, upright side wall is more prone to be installed with water conservancy diversion arm 5, while in use, flexible
The contact area bigger of block piece 6 and water conservancy diversion arm 5, installation is more firm, and sealing function is also more preferable.
As the embodiment that is further improved of flexible block piece 6, the inner wall of the two side walls of the flexibility block piece 6 is right respectively
The outer wall of the water conservancy diversion arm 5 answered is fitted and connected.By above-mentioned connection mode, flexible block piece 6 can be sleeved on two water conservancy diversion arms 5
" outside ", the rainwater left at water conservancy diversion arm 5 at this time can directly prolong water conservancy diversion arm 5 and enter in diversion trench, without flowing through flexible block piece 6
With the edge joint position of water conservancy diversion arm 5, further avoid rainwater and drop onto possibility under bridge, and when flexible block piece 6 and water conservancy diversion arm 5
Connection can also ensure that rainwater will not be flowed under bridge when loosening, thus above structure improves the reliability of the present invention.
As a kind of improvement embodiment of expansion joint sealing structure, elastic waterproof strip 7, the elasticity waterproof strip are further included
7 fillings are fixed between two water conservancy diversion arms 5.On the one hand the effect of elastic waterproof strip 7 can make the first connector 2 and second
Presence abuts power always between connector 3, and two are also can guarantee when the fixation between two connectors and bridge floor 1 loosens
Relative position between connector and bridge floor 1 does not change, and on the other hand, elastic waterproof strip 7 also is able to be flowed at expansion joint
Under rainwater provide first layer blocking, improve expansion joint sealing structure leakproofness.
As a kind of specific embodiment of elastic waterproof strip 7, the elasticity waterproof strip 7 is made of water-swellable material.
Elastic waterproof strip 7 is more in line with expansion joint sealing structure operating mode made of rainwater expanding material, when entering rainwater at expansion joint
Elastic waterproof strip 7 can be expanded with the entrance of rainwater, and stronger abutting power is provided between two connectors, thus above-mentioned
Structure can further improve the sealing performance and reliability of expansion joint sealing structure.
As a kind of improvement embodiment of the first connector 2 and cover board, the cover board and 2 one of the first connector
Molding.Integrally formed cover board and 2 one side of the first connector can reduce the number of components of expansion joint sealing structure, reduce close
The possibility that seal structure loosens when in use；On the other hand, integrally formed cover board and the first connector 2 are in manufacturing process
In can be carried out using only one set of die, it is thus possible to save resources of production, reduce the production cost of sealing structure.
As a kind of improvement embodiment of expansion joint sealing structure, 2 and second connector 3 of the first connector passes through
Bolt is fixed on the correspondence bridge floor 1 of the bridge expanssion joint both sides, first connector 2 and second connector 3 with
Sealant 4 is separately filled between corresponding bridge floor 1.Using sealant 4 and bolt, can by two connectors and bridge floor 1 it
Between consolidate connection, prevent from playing stable impermeable role while loosening between connector and bridge floor 1.
As a kind of improvement embodiment of expansion joint sealing structure, first connector 2 and second connector 3
Cement is separately filled between corresponding bridge floor 1.With the increase of usage time, between the first connector 2 and bridge floor 1 with
And aging can occur for the second sealant 4 between connector 3 and bridge floor 1, influence the sealing effect between connector and bridge floor 1,
At this time cement 8 can 4 aging of sealant to a certain degree when play the role of being glued connector and bridge floor 1, prevent sealing
While 4 ager process of agent, seal failure between connector and bridge floor 1 is prevented.
As a kind of improvement embodiment of expansion joint sealing structure, divide on 2 and second connector 3 of the first connector
It is not provided with the hole for injecting glue 9 suitable for injecting cement in the gap between two connectors and corresponding bridge floor 1.Connect in installation
During fitting, sealant 4 and cement 8 need application respectively, after the sealant 4 between connector and bridge floor 1 solidifies, utilize note
Cement 8 can be refilled between connector and bridge floor 1 by glue hole 9, and therefore, the design of hole for injecting glue 9 can facilitate splicing
The filling of agent 8 ensures that between cement 8 and sealant 4 application can be distinguished.
Obviously, the above embodiments are merely examples for clarifying the description, and is not intended to limit the embodiments.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or
It changes.There is no necessity and possibility to exhaust all the enbodiments.And the obvious variation thus extended out or
Among the protection domain that variation is created still in the utility model.
