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 18 between the second beam body 5, be provided with in described seam 18 and be connected with described first beam body 1 and the second beam body 5
Elastic water-proof connector 10, described elastic water-proof connector 10 is coated with the first comb cover plate 12 and the second comb cover plate 9, institute
State the first comb cover plate 12 and the second comb cover plate 9 above described elastic water-proof connector 10, form cover plate sawtooth district 11, institute
The comb of the comb and the second comb cover plate 9 of stating the first comb cover plate 12 does not connects.Further, described first beam body 1 and
Two beam body 5 are embedded with base plate 8, embedded anchor bar 6 in described first beam body 1 and the second beam body 5, anchor pole 6 towards one end of seam 18
Fix with base plate 8 and be connected, such as, can be welding, so by anchor pole 6, base plate 8 can be firmly fixed to the first beam body 1
One end with the second beam body 5.Installing hole is offered, the first beam body 1 He 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 second beam body 5, water-proof nut 7 can be rustless steel nut, bolt
13 screw in nut 7 through installing hole, so by bolt 13, first comb cover plate 12 and the second comb cover plate 9 are fixed on the end
On plate 8, can also be below the first comb cover plate 12 and the second comb cover plate 9 along nut 7 in order to prevent rainwater from entering along bolt
Sealing packing ring 14 is installed, thus prevents rainwater from entering.It is additionally provided with infundibulate collection in the lower section of described elastic water-proof connector 10
