Abstract
The invention discloses a kind of urban viaduct Single column pier capping beam construction devices, it is characterized in that including the support post for being fixed on bridge pier two sides, passing through the stress truss that suspension cable is supported by bridge pier and support post and the capping beam template being laid in stress truss positioned at bridge pier two sides.The present invention can effectively solve the problems, such as that existing overhead road of city bridge construction causes traffic passage space insufficient, have the advantages that safer, convenient and efficient, save the cost of constructing.
Description
Technical field
The invention belongs to overpass constructing devices, and in particular to a kind of urban viaduct Single column pier capping beam construction device.
Background technique
Currently, urban viaduct Single column pier bent cap generally uses construction area integrally to enclose shelves, Full space support construction lid is set up
Beam.The limitation of existing construction technology:
1, the traffic capacity is greatly reduced: vehicle will be caused impassable after setting up full framing, even if setting up door opening reserves lane,
The traffic capacity will also be greatly reduced；
2, increase traffic navigation pressure: when using raft support method construction Single column pier bent cap, will directly occupy former vehicle and pedestrian
Passage space is bound to cause the increase of other road traffic leading pressure；
3, basement process needs prudent treatment: before setting up full framing, need to conscientiously carry out stiffening basic ground and carry out draining and arrange
Applying, which prevents rainwater from impregnating ground, causes accident resulting from poor quality of projects；
4, safety management difficulty is big: due to being that road occupying is constructed in original path, former multilane sports bicycle road, sends out in the location
Raw vehicle mutually knocks into the back, the probability of grazing will increase or even vehicle crash anti-collision wall causes stent migration to collapse to be likely to.
Summary of the invention
The purpose of the present invention is causing traffic passage space insufficient for existing overhead road of city bridge construction, one kind is provided and is more pacified
Entirely, the urban viaduct Single column pier capping beam construction device of convenient and quick construction, save the cost.
Realize the object of the invention the technical solution adopted is as follows:
Urban viaduct Single column pier capping beam construction device provided by the invention, support post, position including being fixed on bridge pier two sides
Pass through the stress truss that suspension cable is supported by bridge pier and support post and the capping beam template being laid in stress truss in bridge pier two sides.
The bottom end of the support post is mounted on the pre- bracket for being embedded in bridge pier and fixes with the bridge pier, the support post
Top is provided with tensioning and pre-tightens platform, and the pier stud end of the stress truss is mounted on the pre- bracket for being embedded in bridge pier by the bridge pier
Support, the cantilever end of stress truss pre-tighten platform with tensioning by anchorage beam and are connected with suspension cable by the support post branch
Support.
Beneficial effect
Support post, capping beam template, stress truss, pre-buried bracket, tensioning in the present invention pre-tighten platform, anchorage beam and oblique pull
Rope is the common used material of project construction, strong applicability；Without carrying out basement process, save the cost；Original road is not changed
Space can maintain original traffic navigation scheme, not will cause " bottleneck " phenomenon, and safety is secure；Support post, bent cap bed die,
Stress truss, pre-buried bracket, tensioning preload platform, anchorage beam and suspension cable can be made into sub-assembly, and installing and dismounting is easy to operate
And it is reusable, accelerate construction speed；Top tensioning pre-tightens platform can adjust stress at any time, accomplish that stress can
Control, quality are secure；Full framing is substituted with support post and suspension cable, reduces construction investment.
Technical solution of the present invention is further illustrated with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is sectional view along AA in Fig. 1.
Specific embodiment
As shown in Figure 1, 2, urban viaduct Single column pier capping beam construction device provided by the invention, including it is fixed on bridge pier two
The support post 3 of side, the stress truss 5 supported by support post 3 positioned at bridge pier two sides by suspension cable 2 and in stress truss 5
The capping beam template 4 of laying；The bottom end of the support post 3 is mounted on the pre- bracket 7 for being embedded in bridge pier and fixes with the bridge pier, institute
It states 3 top of support post and is provided with tensioning preload platform 1, the pier stud end of the stress truss 5 is mounted on the pre- ox for being embedded in bridge pier
It is supported on leg 7 by the bridge pier, the cantilever end of stress truss 5 pre-tightens the suspension cable 2 of platform 1 by anchorage beam 6 and tensioning and connects
It connects and is supported by the support post 3.
When Coping Construction, using Inclined cable-stayed construction with brackets, support post 3 is mounted on pre-buried bracket 7 with crane,
Crane lifts by crane stress truss 5, and 5 pier stud end of stress truss is mounted on pre-buried bracket 7, the suspension cable 2 that cantilever end will anchor
Button hangs over tensioning and pre-tightens on platform 1, removes crane, and presetting 2 length of suspension cable makes stress truss 5 be substantially at bent cap bottom plate flat
Surface state is laid with bent cap bed die, adjusts suspension cable 2, rotary ligating cover beam steel, installation side form forms capping beam template 4, in capping beam template
Bent cap concrete is poured in 4 forms bent cap.
