It is finally post-cast strip, tool is modeled between upper and lower fixed section pier shaft, sockets long reinforcing bar, fixed section built-in fitting, pier shaft
All packet is in mold for connector and connection regulating part, and then, the concrete perfusion in mold, post-cast strip concrete is using fast hard
Concrete, the presetting period be less than or equal to 1 hour, 4 hours intensity can reach 50% or more design strength, will to socket long reinforcing bar,
Pier shaft connector and connection regulating part all wrap up, by one complete pier of upper and lower fixed section pier shaft and variable field pier shaft
Column.
Bridge pad 22 is installed on bent cap 52, concave surface pedestal 23 is anchored to the supporting part of beam body, the supporting part and beam
Body support installation site is corresponding, and fastening bolt 243 is passed through through-hole 242, concave surface pedestal 23 is connect with spherical crown Universal-head 24,
Since through-hole 242 and aperture are greater than the diameter of fastening bolt 243, fastening bolt 243 has mobile space in through-hole, by spherical crown ten thousand
To first 24 bottom surface be adjusted to 22 end face same plane of bridge pad, make the universal built-in fitting in top surface on beam body support 22 and support
21 remain horizontal closely connected, then, fastening bolt 243 is fixed, are fixed with the bridge of the universal built-in fitting 21 in top surface on support
It is erected on bridge pad 22.
After the completion of bridge erection, expansion joint is equipped between adjacent two bridge 61, in expansion joint two sides beam body or abutment coagulation
Pre-buried fashioned iron consolidates built-in fitting 31 respectively in native, then floor 35 is fixed on consolidation built-in fitting 31, a consolidation built-in fitting 31
Multiple floors 35 are equipped with, each floor is equipped with gradient adjustable comb tooth plate 32, which passes through fixed spiral shell
Bolt 33 and floor 35 are fixed, and the floor of expansion joint two sides is in dentation cross-over design, which is wedge configuration, can
Prefabricated, replacement, quick release, replacement are carried out according to actual grade variation, the lower section of floor is equipped with pair of pages formula infiltration diversion trench
34, which includes upper diversion trench and lower diversion trench, and the upper diversion trench and lower diversion trench are distinguished in the beam body of expansion joint two sides,
The outer of lower diversion trench is entirely fallen within below the projection of diversion trench, and lower diversion trench accepts the runoff overflowed from upper diversion trench, will
The deck runoff fallen at expansion joint is guided to except bridge, bent cap pier, prevents water flow from directly washing away component and support.
It is described quickly to adjust expanded joint structure, adjusting expansion joint top surface slope can be reached by replacing gradient adjustable comb tooth plate
The effect of degree.
The two sides of bridge floor be equipped with linear adjustable railing and anti-collision wall, the linear adjustable railing include scalable skeleton 41,
Protective plate 42, railing 43, scalable 41 both ends of skeleton are separately fixed at end of the front and back two across anti-collision wall 7, described to stretch
Contracting skeleton has impact strength and rigidity, and is able to achieve a certain range of flexible and swinging deformation ability, the protective plate
42 be van-type structure, is wrapped in the scalable skeleton periphery, forms enclosed construction, prevent rainwater from directly washing away scalable bone
Frame, the railing include chain bar 43 and column 44, and the chain bar 43 can pass through chain bar free end by hingedly connecting with column 44
431 slide the linear, change in displacement of adaptation in sliding slot 432.
Linear adjustable railing and anticollision wall construction pass through scalable skeleton, protective plate and railing in a certain range flexible
Adaptive deformation can be voluntarily adjusted, and continue original after two bridge body relative attitudes changes in front and back with swinging deformation ability
Collision prevention function.
Present bridge when not being able to satisfy current requirement or safety problem demand lifting bridge needs that pier shaft is asked to be lifted
Rise transformation, adaptation step are as follows:
Step 1: loosening the fastening bolt 243 between concave surface pedestal 23 and spherical crown Universal-head 24, fixation supports pier stud
Upper fixed section pier shaft 111, upper fixed section pier shaft falls after preventing post-cast strip from removing；
Step 2: removal variable field pier shaft 113 can concrete on post-cast strip 15, make pier shaft connector 13, connection is adjusted
It saves part 14 and is all exposed to long reinforcing bar 12 is socketed；
Step 3: the bolt on pier shaft interconnecting piece 132 and connection regulating part 14 is removed, makes to connect regulating part and pier shaft connects
Socket part 132 separates, and turns to the screw rod collar nut for socketing long reinforcing bar, makes first, second pair to socket long reinforcing bar separation；
Step 4: upper fixed section pier shaft 111 is lifted to presetting height, adjustment concave surface pedestal 23 and spherical crown Universal-head 24
Position so that the universal built-in fitting 21 in top surface and bridge pad 22 is remained horizontal by the rotation of spherical crown Universal-head
It is closely connected, prevent horizontal component；
Step 5: it is previously fabricated with the connection regulating part that is consistent of design rising height, after the connection regulating part and lifting
Upper and lower 132 height of pier shaft interconnecting piece is adapted, and passes through the first bolt hole and the second bolt hole with bolt, new connection is adjusted
Part and upper and lower pier shaft interconnecting piece 132 fasten, make upper and lower pier shaft interconnecting piece 132 with connect regulating part and be linked together again, turn
Screw rod collar nut adjusts first, second pair and sockets long reinforcing bar, and the fixed section preburying part 131 of upper and lower fixed section pier shaft is tensed,
If the adjustment of screw rod collar nut is not able to satisfy the requirement of lifting, just cut off original all to socketing long reinforcing bar, weight
It newly arranges and welds first, second pair of anchoring and socket long reinforcing bar, then tense first, second pair by screw rod collar nut and socket length
Reinforcing bar；
Step 6: being poured post-cast strip again, long reinforcing bar, fixed section built-in fitting, pier shaft connector and connection will be socketed and adjusted
All packet is in mold for part, then, the concrete perfusion in mold.
Step 7: to self-leveling type seat structure, can quickly adjust expanded joint structure, linear adjustable railing and anti-collision wall structure
It makes after pier stud height adjustment, can form new structural regime by artificially adjusting or adaptation function, reach bridge use
It is required that.
Disclosed above is only specific embodiments of the present invention, the embodiment be only it is clearer illustrate used in the present invention,
And not limitation of the invention, the changes that any person skilled in the art can think of should all be fallen in protection scope.
