Background technology
When bridge design, bridge panel can expand due to reasons such as variations in temperature or shrink, and will arrange a shrinkage joint between each adjacent bridge panel of therefore every two predetermined beam lengths, bridge dilatation in the longitudinal direction can be born primarily of bridge expanssion joint.
At present, bridge expansion joint installation has polytype, modal modulus type shrinkage joint arranges two cross section " F " shapes, " E " shape shaped steel by bilateral symmetry, centre arranges " king " type cross section shaped steel of varying number, and then the rubber fastening band of V-arrangement is set between two root type steel, between shaped steel gap, flow into bridge substructure to prevent rainwater.At present, the shaped steel cross section used in bridge expansion joint installation mostly is " F " shape, " C " shape or " E " shape.But when environment temperature changes, can there is telescopic moving in pontic, and the gap between the shaped steel of shrinkage joint also can broaden or narrow.Gap between shaped steel is often uneven.For this situation, gap method of adjustment conventional is at present spring-compressed dynamic balance, a kind of expanded joint structure that automatically can adjust gap as just disclosed in Chinese patent (200710008708.1), it comprises two L-type steel plates, two blocks of shrinkage joint steel plates and at least one piece of expansion plate and support steel bar, spring sleeve between shrinkage joint steel plate and expansion plate overlaps and has buffer spring, but this method, by the impact of various resistance uneven phenomenon, is difficult to accomplish that shaped steel gap uniformity is with consistent.
And the working environment of bridge extension joint is complicated, severe, should directly stand wind and weather, solar exposure, also will bear horizontal impact and the friction of wheel of vehicle, also to bear the fatigue impact caused by bridge construction distortion simultaneously; Because stretching device main body is positioned at directly over bridge construction breaking joint, the stretching device that structural performance is comparatively weak is just in time positioned at bridge construction breaking joint place, and these two kinds " weaknesses " coexist a place, in conjunction with aforesaid environment reason, stretching device is caused to there is cracky, the problems such as application life is short; Simultaneously, existing bridge extension joint is all generally be the permanent device of globality structure with bridge, once occur damaging or leaking, can only carry out local maintenance, maintenance is long in time limit, and operation extremely bothers, many times automobile is uneven in driving process above, fluctuate up and down, to driving, personnel make troubles, so existing bridge expanssion joint linkage is still perfect not.
Utility model content
The purpose of this utility model is: provide the noise that a kind of structure is simple, reduce touching linkage when vehicle travels on bridge, reduce car to the shaking force of bridge, extend the life-span of bridge, life-span can reach 10-50, length that can be concrete according to bridge connecting sewing, can assemble at scene, need not produce at factory building in advance, decrease the time of product in shop assembled, instant packed transport, save the tooth-like Highway Bridge Expansion Joint linkage of manpower and materials, to overcome the deficiencies in the prior art.
The utility model is achieved in that tooth-like Highway Bridge Expansion Joint linkage, expansion joint connecting device is connected to form by flexible connecting rod by symmetrical left module and right module, described left module and right module are linked into an integrated entity by connecting rod by the first brace and the second contiguous block, the second contiguous block is provided with between described two adjacent the first braces, adjustment platform is provided with between two the first braces, adjustment platform is provided with adjustment bolt, between left module and right module, is provided with waterproof sand prevention groove.
Described first brace comprises " Z " font brace, and rectangular connecting sheets and semicircular arc brace, the first brace is provided with teeth groove and hole.
Described first brace and the second contiguous block are provided with the flexible connecting rod bores that flexible connecting rod can be allowed to insert.
Described first brace and the second contiguous block are provided with the connecting rod bores that connecting rod can be allowed to insert.
Described flexible connecting rod is connected to form by front rod and back link, front rod is provided with threaded termination, back link is provided with connecting hole.
First brace and the second contiguous block are provided with the groove snapping in waterproof sand prevention groove.
Owing to have employed technique scheme, compared with prior art, the utility model effectively can reduce the noise touching linkage when vehicle travels on bridge, reduces car to the shaking force of bridge, extends the life-span of bridge, and this product can be concrete according to bridge connecting sewing length, can assemble at scene, need not produce at factory building in advance, decrease the time of product in shop assembled, instant packed transport, has saved the advantages such as manpower and materials.
