The utility model content:
The purpose of this utility model provides a kind of long service life, adapts to various displacements, car load can be passed to the beam body reliably, and stretching device respectively stitches wide modulus formula shaped steel stretching device even, easy to replace and maintain.
The utility model is achieved in that
The utility model modulus formula shaped steel stretching device, be included in two side bars 3 of bridge plate seam crossing both sides, the some central sills 4 that between two side bars 3, are arranged in parallel, rubber seal tape 8 is arranged between side bar and the central sill and between the central sill, side bar 3 is connected with some supported boxs 1, central sill 4 is connected with some frame support brackets 6, the frame support bracket 6 of coaxial line compresses supporting with supported box 1 and is connected with a bearing cross beam 11 with sliding bearing, supported box 1 is anchored in the concrete of bridge plate seam crossing both sides, the two side of frame support bracket 6 is fixed with shear spring 10, junction plate connects the shear spring on the adjacent frame support bracket sidewall 10, some parallel central sills 4 are segmented at least two stretching device modules by the track, adopt bolt to connect between the module.
The bottom of the central sill 4 of the coaxial line of two stretching device modules is connected with bolt 23 by junction plate 22, and the two side of the central sill of coaxial line is connected with bolt 20 by briquetting 19,21, and central sill 4 is connected with frame support bracket 6 by bolt 7.
There is lubrication channel 26 at the center that compresses supporting and sliding bearing that is connected with supported box 1.
The shear spring 10 of the every side of bearing cross beam connects into crest two curves opposite with trough by junction plate.
Said junction plate is a T type frame 5, and the center pillar of T type frame 5 is connected with frame support bracket 6, and the Ji, both sides is connected with a shear spring 10 respectively, and shear spring 10 is connected with supported box 1 by junction plate 9.
The utility model can carry out segmentation by the track, and every section is a stretching device module, connects with bolt between the module, and is easy to replace and maintain.Displacement control system adopts many group shear springs, and every group of shear spring can both be controlled the stretching device displacement separately, when one group of displacement control element destroys, can not influence whole displacement control system, has multiple insurance function; Shear spring is symmetrically distributed in the bearing cross beam both sides, formed the moment of couple of cancelling out each other between many group shear springs, when the stretching device displacement, the moment that shear spring produces is cancelled out each other, guaranteed that the power that shear spring produces can not act on the central sill, has optimized the stressed of central sill.
The center that compresses bearing and sliding support under the side bar in the supported box is provided with the self-lubricate passage, supplies with lubricious automatically and eliminating bearing slide surface dust by the automatic sliding system of a cover, the application life of improving bearing.
The beneficial effects of the utility model are:
1. organize the shear spring displacement control system more and guaranteed that big displacement shaped steel stretching device respectively stitches wide uniformity;
2. displacement control system can be optimized the stressed of central sill;
3. can keep in repair on the road surface;
4. can carry out the replacing and the maintenance of whole component to one-lane stretching device;
5. supported box is less, can guarantee installation quality reliably.
6. bearing has the self-lubricate function, has improved the application life of bearing greatly.

The specific embodiment:
The shear spring displacement control system has supported box 1, spring coupling plate 9, shear spring 10, frame support bracket 6, T shape frame 5 to be connected with the mode of bolt 13 with series connection by bolt 12, supported box 1 is fixed on the side bar 3, shear spring 10 is fixed on the both sides of frame support bracket 6, frame support bracket 6 is fixed on the bearing cross beam 11 by compressing supporting 24 and sliding bearing 25, central sill 4 is fixed on the frame support bracket 6, and the shear spring 10 of series connection is wide by the seam between supported box 1, T shape frame 5 and frame support bracket 6 control two side bars 3 and each central sill 4.Many group shear spring 10 control stretching device displacements are arranged, and every group of shear spring 10 can both independently be controlled the stretching device displacement, has multiple protection functions.Shear spring 10 is distributed in frame support bracket 6 both sides, organizes to form the opposite couple of direction between the shear spring 10 more, and the resultant couple square is 0.
Supporting system has supported box 1 to be fixed on the side bar 3, sliding bearing 15 in the supported box 1 and compress supporting 14 bearing cross beam 11 is embraced, frame support bracket 6 is fixed on the bearing cross beam 11 by compressing supporting II24 and sliding bearing 25, central sill 4 is fixed on the frame support bracket 6, so just the load that central sill can be born through frame support bracket 6, compress supporting 24, sliding bearing 25, bearing cross beam 11, compress supporting 14, sliding bearing 15 passes to beam body and the abutment that links to each other with supported box with supported box 1.
Bicycle road modules A, B is respectively a stretching device module, and (number of track-lines according to the road surface carries out segmentation, there are several tracks just to divide several sections), the A section is an emergency stopping lane only stretching device module, the B section is a slow lane stretching device module, can establish the C section is runway stretching device mould, the D section is a fast stretching device module, pass through shaped steel briquetting 16 between each module, screw 17, sealing rubber pad 18, briquetting 19, bolt 20, briquetting 21, gusset piece 22 and bolt 23 link together and form the whole piece stretching device, like this when the stretching device in a track is damaged, the replacing and the maintenance of bicycle road stretching device be can realize, oblique rope bridge and suspension bridge are specially adapted to.
Self-lubricating structure: sliding bearing 15 and compress supporting 14 central authorities one self-lubricate passage 26 is arranged, supply with automatically by the automatic feed system of a cover, realize self-lubricate.
The stroke of this shaped steel stretching device adjacent beams (side bar 3 or central sill 4) is 0～80mm, and be that modulus increases progressively with 80mm, adjacent beams (side bar 3 or central sill 4 upper side between have a rubber seal tape 8 to link to each other, the two ends plush copper of rubber seal tape is embedded in the die cavity of side bar 3 or central sill 4; Dismantle bolt 7 under the central sill just can keep in repair each element under the central sill on the road surface.
