Description
Technical field
Patent of the present invention relates to a kind of tooth-like Highway Bridge Expansion Joint attachment means and preparation method thereof, belongs to Highway Bridge Expansion Joint attachment means technical field.
Background technology
When Bridge Design, bridge panel can due to reasons such as variations in temperature expansion or shrinkage, therefore an expansion joint is set between each adjacent bridge panel of the predetermined beam length of each two, bridge dilatation in the longitudinal direction can mainly be undertaken by bridge expanssion joint.
At present, bridge expansion joint installation has polytype, modal modulus type expansion joint is to be arranged two cross section " F " shapes, " E " shape shaped steel by lateral symmetry, centre arranges " king " type cross section shaped steel of varying number, the rubber fastening band of V shape is set between two root type steel the most again, to prevent rainwater from flowing into bridge substructure between shaped steel gap.At present, the shaped steel cross section used in bridge expansion joint installation mostly is " F " shape, " C " shape or " E " shape.But, when ambient temperature changes, pontic can occur telescopic moving, the gap between the shaped steel of expansion joint also to broaden or narrow.Gap between shaped steel is the most uneven.For this situation, the most conventional gap method of adjustment is spring-compressed dynamic balance, such a as the openest in Chinese patent (200710008708.1) can adjust the expanded joint structure in gap automatically, it includes two L shape steel plates, two blocks of expansion joint steel plates and at least one piece of expansion plate and support steel bar, it is cased with buffer spring on spring sleeve between expansion joint steel plate and expansion plate, but this method is affected by various resistance uneven phenomenon, it is difficult to accomplish that shaped steel gap uniformity is with consistent.
And, the working environment of bridge extension joint is complicated, severe, should be directly subjected to wind and weather, solar exposure, still suffer from horizontal impact and the friction of wheel of vehicle, still suffers from the tired impact caused by bridge structure deformation simultaneously；Owing to retractor device main body is positioned at the surface of bridge structure breaking joint, the retractor device that structural behaviour is more weak is placed exactly at bridge structure breaking joint, and both " weak " is with at one, in conjunction with aforesaid environment reason, cause the problems such as retractor device exists cracky, and service life is short；Simultaneously, existing bridge extension joint is typically all and the permanent device that bridge is globality structure, once occur damaging or leaking, can only carry out local maintenance, maintenance is long in time limit, and operates cumbersome, many times automobile is uneven in driving process above, fluctuating up and down, to driving, personnel make troubles, so existing bridge expanssion joint attachment means is the most perfect.
Summary of the invention
It is an object of the invention to: a kind of simple in construction is provided, reduces the noise of touching attachment means when vehicle travels on bridge, reduce the car shaking force to bridge, extend the life-span of bridge, life-span can reach 10-50, can be according to the concrete length of bridge connecting sewing, can assemble at scene, need not produce at Factory Building in advance, decrease the product time in shop assembled, instant packed transport, tooth-like Highway Bridge Expansion Joint attachment means having saved manpower and materials and preparation method thereof, to overcome the deficiencies in the prior art.
nullThe present invention is achieved in that the manufacture method of tooth-like Highway Bridge Expansion Joint attachment means，Described expansion joint connecting device is connected by two left mould blocks symmetrically and being connected in one by flexible connecting rod and right module and forms，Described left mould block and right module are by connecting sheet and contiguous block is linked into an integrated entity by connecting rod，Teeth groove and hole is had connecting to make on sheet，When left mould block or right module are connected with bridge panel，The combination dynamics with cement is increased by connecting the teeth groove on sheet and hole，Increase structural capacity，Make between two adjacent connection sheets and have adjustment platform，Adjustment bolt is had adjusting to make on platform，Adjust bolt by regulation and can ensure that expansion joint connecting device is concordant with road surface，Left mould block and right module can left and right or carry out relative motion up and down by the connection of flexible connecting rod，Ensure that the structural stability of expansion joint connecting device.
Expansion joint connecting device is consisted of the connection of flexible connecting rod symmetrical left mould block and right module, described left mould block and right module are by connecting sheet and contiguous block is linked into an integrated entity by connecting rod, it is provided with contiguous block between described two adjacent connection sheets, connect at two and be provided with adjustment platform between sheet, it is provided with adjustment bolt adjusting on platform, between left mould block and right module, is provided with waterproof sand prevention groove
