Description
Technical field
This utility model relates to bridge, relates more specifically to a kind of bridge comb expansion joint.
Background technology
Bridge is influenced by temperature and can expand with heat and contract with cold, and crossstructure generation can be had a strong impact on by this expanding with heat and contract with cold,
Would generally arrange expansion joint at present on bridge to eliminate this impact, expansion joint can be stretched along with expanding with heat and contract with cold of pontic
Contracting, thus reduces the stress of bridge.Yet with the existence in gap, rainwater can pour into inside bridge, produces pontic and destroys,
In order to prevent rainwater from pouring into, in current highway bridge construction, expansion joint sealing generally uses rubber fastening band sealing, expansion joint two
Side anchor plate protection, Interal fixation connects two beam body, can be squeezed at beam body deformation process light plate, be deformed,
Steel plate is heaved, and structural gap occurs, and this gap can cause rainwater to pour in expansion joint, causes vehicular traffic tire simultaneously
Infringement, affects vehicle driving comfort, and along with China's outdoor environment changes, bridge runs the time limit to be increased, and ageing of rubber is damaged tight
Weight, it is difficult to change, till causing bridge expansion joint, seepage is serious, and bridge is caused the infringement in outward appearance and structure by rain erosion.Rubber
It is big that workload changed by glue waterstop, disposes difficulty, long in time limit, bigger to traffic impact.

Accompanying drawing explanation
Fig. 1 is the sectional structure chart at this utility model expansion joint；
Fig. 2 is the plane structure chart at this utility model expansion joint.
Detailed description of the invention
Understandable for enabling above-mentioned purpose of the present utility model, feature and advantage to become apparent from, below in conjunction with the accompanying drawings to this
The detailed description of the invention of utility model is described in detail, and makes above and other purpose of the present utility model, feature and advantage incite somebody to action
Become apparent from.The part that reference instruction identical in whole accompanying drawings is identical.Accompanying drawing the most drawn to scale, emphasis
It is purport of the present utility model is shown.
As shown in Figure 1, 2, a kind of bridge comb expansion joint, including the first beam body 1 and the second beam body 5, described first beam body 1
And form seam 3 between the second beam body 5, in described seam 3, be provided with the bullet being connected with described first beam body 1 and the second beam body 5
Property waterproof connector 10, described elastic water-proof connector 10 is coated with the first comb cover plate 12 and the second comb cover plate 9, described
First comb cover plate 12 and the second comb cover plate 9 form cover plate sawtooth district 11 above described elastic water-proof connector 10, described
The comb of the first comb cover plate 12 and the comb of the second comb cover plate 9 do not connect.Further, described first beam body 1 and second
Beam body 5 is embedded with base plate 8, embedded anchor bar 6 in described first beam body 1 and the second beam body 5, anchor pole 6 and the end towards one end of seam 3
Plate 8 is fixing to be connected, such as, can be welding, so passes through anchor pole 6 and base plate 8 can be firmly fixed to the first beam body 1 and the
One end of two beam body 5.Installing hole is offered, the first beam body 1 and second on described first comb cover plate 12 and the second comb cover plate 9
Being embedded with the water-proof nut 7 corresponding with described installing hole in beam body 5, water-proof nut 7 can be rustless steel nut, and bolt 13 is worn
Cross installing hole and screw in nut 7, so by bolt 13, first comb cover plate 12 and the second comb cover plate 9 are fixed on base plate 8
On, between described elastic water-proof connector 10 and described cover plate sawtooth district 11, it being provided with guiding gutter 2, guiding gutter 2 prolongs along seam 3
Stretching, until stretching out seam 3, guiding gutter 2 can use rubber to make, and guiding gutter 2 at least includes groove portion 4 He being positioned in seam 3
Be positioned on base plate 8 along portion 14, will be compressed along portion 14 by the first comb cover plate 12 and the second comb cover plate 9, such guiding gutter 2
Just it has been fixed at seam 3.Embedded anchor bar 6 is made up of horizontal anchor pole 16 and vertical anchor pole 15, at the first comb cover plate 12 and
Gap between two comb cover plates 9 and beam body irrigates microdilatancy mortar 7, further to stop rainwater to enter.
During this is novel, elastic water-proof connector 10 is made up of multiple rows of low-density close vinylacetic acid fiber element, vinyl
Acetate fiber has good retractility, can along with the flexible of pontic seam 3 dilatation, utilize good waterproof of this material
The sealing of sexual satisfaction bridge expanssion joint needs, and is got up with base plate 8 bonding by elastic water-proof connector 10 by epoxide-resin glue, lid
Between the comb in bladed saw tooth district 11, tooth pitch can become big or reduce along with the flexible of seam 3, so by the first comb cover plate
12 and the second comb cover plate 9 two such cover plate so that seam 3 can not interfere with cover plate with Free Transform, and cover plate also will not produce
Raw bulging deformation, thus reduce the generation in gap, improve the comfortableness that vehicle travels, reduce the damage to tire；Further
, for penetrating into a small amount of rainwater in gap, it is collected by guiding gutter 4, outside the rainwater etc. of collection is discharged to gap, this
Expansion joint would not be produced and damage by sample rainwater.This expansion gap device is that bridge expanssion joint is flexible and sealing requirement in order to meet, with
Time reduce impact on vehicle pass-through, meet current facility.
