Abstract
The utility model provides a bridge comb type expansion device, comb type teeth (11) of a comb type plate and comb type teeth (21) of a comb type plate (2) are in relative misplacement arrangement, the bottom faces of the comb type plate (1) and the comb type plate (2) are respectively connected with a plurality of anchor plates (3), and each anchor plate (3) is connected with anchor reinforced bars (4). The bridge comb type expansion device is stable and comfortable in operation, low in manufacturing and mounting cost and long in service lift, and is safe and reliable.
Description
Technical field:
The utility model is relevant with bridge extension joint, and is special relevant with bridge interdigitated electrode structure stretching device.
Background technology:
At present in the bridge extension joint of stroke in 40～160mm scope, what mainly adopt is shaped steel modulus formula stretching device, such stretching device is a modulo unit with 80mm, stroke less than 80mm by two deformed steels, band and anchor system are formed single seam stretching device, 80～160mm increases central sill shaped steel on single seam stretching device basis, the displacement case, parts such as control spring are formed the double slit stretching device, such stretching device is because reservation shrinkage joint and direction of traffic are angled, traffic blows power is big, stretching device destroys easily, and the stationarity of driving a vehicle simultaneously and comfortableness are poor.A kind of assemble comb-type stretching device, though driving stationarity and comfortableness all are improved, movable and fixing comb template anchor bolt is loosening easily, causes potential safety hazard, makes and the installation cost height in addition, does not obtain large-scale promotion at present and uses.
The utility model content:
The purpose of this utility model is in order to overcome above deficiency, to provide a kind of driving steady, comfortable, make and installation cost low, safe and reliable, the interdigitated electrode structure stretching device of long service life.
The purpose of this utility model is achieved like this:
The utility model bridge interdigitated electrode structure stretching device, the comb type tooth 11 that it is characterized in that combing on the template 1 is arranged with the comb type tooth 21 relative dislocation on the comb template 2, be connected with polylith anchor plate 3 respectively at comb template 1 and comb template 2 bottom surfaces, be connected with anchor bar 4 above the every anchor plate 3, anchor bar can form with circular bar bending.
Above-mentioned polylith anchor plate 3 is connected to comb type tooth 11,21 bottom surfaces, to strengthen the rigidity of comb type tooth.
The bearing support 5 that band sealing band 6 is arranged below the above-mentioned comb template 1,2.
Above-mentioned bearing support 5 cross sectional shapes are inverted L shape, have breach 51 on it, can adopt angle steel to make.
Above-mentioned bearing support 5 cross sectional shapes are the I type, can adopt band steel to make.
Because the direction of comb type tooth is parallel with direction of traffic, wheel keeps touching with comb type toe joint always simultaneously in the utility model, and it is steady, comfortable to drive a vehicle, and does not have the car of jumping phenomenon; Manufacturing and installation cost are low, adopt the structure of shaped steel modulus formula stretching device anchor plate and anchor bar, and bolt anchoring system that need not comb type stretching device, not only install easily simple, outside installation quality can be guaranteed, also avoid adopting nut loosening in the bolt anchoring system, cause the disadvantage of potential safety hazard, safe and reliable, long service life.

The specific embodiment:
Embodiment 1:
Fig. 1～Fig. 4 has provided present embodiment 1 structural representation.The bridge expanssion joint of the suitable especially stroke of present embodiment in 80～160mm scope uses.As shown in Figure 1 and Figure 2, the comb type tooth 21 relative dislocation of the comb type tooth 11 of comb template 1 one ends and comb template 2 one ends are arranged, the direction of comb type tooth and direction of traffic keeping parallelism simultaneously, wheel is touched with comb type toe joint always, it is steady, comfortable to drive a vehicle, and has avoided shaped steel modulus formula stretching device need reserve impact and the jumping car phenomenon that seam causes because of structure.Polylith anchor plate 3 directly is welded on comb type tooth 11 and comb type tooth 21 bottom surfaces respectively, has increased the moment of inertia of comb type tooth, has improved comb type tooth bending rigidity, thereby can increase comb type tooth, realizes the purpose that stroke increases.The anchor bar 4 of corresponding welding above every anchor plate 3 and embedded bar 7 welding, the concrete eight by new cast connects as one comb template 1,2 and beam body.As shown in Figure 3, Figure 4, have breach 51 on the bearing support 5, so that bearing support 5 is when being welded on comb type tooth 11 and the comb template 2, anchor plate 3 staggers.Rubber sealing band 6 is anchored on the bearing support 5, because rubber sealing band 6 is in below the comb template fully, does not directly contact with wheel, and is not fragile.
Embodiment 2:
Claims (5)
1, bridge interdigitated electrode structure stretching device, the comb type tooth (11) that it is characterized in that combing on the template (1) is arranged with the relative dislocation of comb type tooth (21) on the comb template (2), be connected with polylith anchor plate (3) respectively at comb template (1) and comb template (2) bottom surface, be connected with anchor bar (4) above the every anchor plate (3).
2, bridge interdigitated electrode structure stretching device according to claim 1 is characterized in that polylith anchor plate (3) is connected to comb type tooth (11,21) bottom surface.
3, bridge interdigitated electrode structure stretching device according to claim 1 and 2 is characterized in that combing the bearing support (5) that band sealing band (6) is arranged below the template (1,2).
4, bridge interdigitated electrode structure stretching device according to claim 3 is characterized in that bearing support (5) cross sectional shape is an inverted L shape, has breach (51) on it.
5, bridge interdigitated electrode structure stretching device according to claim 3 is characterized in that bearing support (5) cross sectional shape is the I type.
