Clearly and completely describe, it is clear that described embodiment is only this utility model a part of embodiment, rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The all other embodiment for being obtained, belongs to the scope of this utility model protection.
Referring to Fig. 1 and Fig. 2, the modulus type that a kind of waterproof adhesive tape of this utility model embodiment offer has lower support stretches
Device 1, including two side bars 11, side bar 11, at the concrete 21 of 2 both sides of expansion joint, is vertically phase between two side bars 11
To arranging, retractor device 1 also includes joist 12 and at least one central sill 13, each central sill 13 may be contained within two side bars 11 it
Between, and along the length direction interval setting successively of joist 12, each central sill 13 with and its just to side bar 11 or it is another in
Connected using waterproof adhesive tape 14 between beam 13, joist 12 across described expansion joint 2 and be located at two side bars 11 and it is each in
The underface of beam 13, forms the vertical supporting to above-mentioned each beam, two ends along its length of joist 12 by joist 12
Slip bearing 16 is respectively adopted and stationary balls bearing 15 is installed on the concrete 21 of 2 both sides of expansion joint.This enforcement
In example, connected using the sealing of waterproof adhesive tape 14 between adjacent side bar 11 and central sill 13 and between adjacent two central sills 13
Connect, while the telescopic variation at expansion joint 2 is adapted to, meet the waterproof requirement at expansion joint.Meanwhile, the wherein one end of joist 12
Installed on concrete 21 using stationary balls bearing 15, the other end is installed in opposite side concrete by slip bearing 16
On 21, when 2 telescopic variation of expansion joint, joist 12 can be relatively fixed steel ball bearing 15 and move with slip bearing 16, with
This telescopic variation at expansion joint 2 is adapted to, and be can adapt to during automotive wheel is travelled to the multidirectional of the generation of retractor device 1
Displacement.
Referring to Fig. 2-Fig. 4, optimize above-described embodiment, each waterproof adhesive tape 14 is bent successively along the length direction of joist 12,
And 133 inner surface of the top board laminating respectively with corresponding side bar 11 or correspondence central sill 13 of its both ends.In the present embodiment, marine glue
More than 14 bending of bar, which has profile of at least part of structure in wavy multiple bending, and which has along the length direction of joist 12
There is preferable elasticity, be adapted to the deformation requirements at expansion joint 2；Meanwhile, waterproof adhesive tape 14 adopts this foldable structure profile, makes
The main telescopic variation which compares traditional adhesive tape is horizontal by vertically switching to；Gap phase between adhesive tape and side bar 11, central sill 13
Traditional flying bird formula waterproof adhesive tape is greatly decreased, reduce rubbish etc. accumulation, simultaneously because fold after waterproof adhesive tape 14 wave
Shape is in multiple bending structure profile, after stone or silting are to waterproof adhesive tape 14, when 1 overall shrinkage of retractor device
When, by 14 telescopic variation of waterproof adhesive tape, will can accumulate in stone or silt on waterproof adhesive tape 14 by two side bars 11 it
Between extrude, take out of with wheel, so as to reach the purpose of slagging-off.
Continue optimization above-described embodiment, each side bar 11 is respectively provided with to the first horizontal-extending slide plate 111 of correspondence central sill 13,
The two relative side of each central sill 13 is respectively provided with the second horizontal-extending slide plate 131, per one second slide plate 131 and corresponding first
Partly overlap between slide plate 111 or corresponding second slide plate 131, and each first slide plate 111 is respectively positioned on each second slide plate 131
The underface of correspondence waterproof adhesive tape 14.In the present embodiment, the first slide plate 111 and the second slide plate 131 are overlapped or two second cunnings
Overlap between plate 131, form overlap joint.When expansion joint 2 deforms, corresponding first slide plate 111 and second is gone up in the horizontal direction and is slided
Relative slip can be formed between plate 131 or between two the second slide plates 131, i.e., both are without limitation on the flexible of expansion joint 2
