Description
Technical field
The utility model belongs to supporting bridge for reinforced liner system truss technology field, more particularly to a kind of bridge
Support is reinforced with bridge steel tubular pole strutting system and supports truss with truss adjustable scissors.
Background technique
In the road constructions such as highway, railway, cast-in-situ bridge construction is frequently involved, needing to build bridge supports fixation
Frame, i.e. bridge steel tubular pole strutting system, which are reinforced, supports truss with truss adjustable scissors, for facing two supporting bridge columns
When the fixed cast-in-place construction in order to bridge transverse slat.
Traditional supporting bridge fixed frame generally uses two cross bars and a brace to weld respectively with two supporting bridge columns
It connects in succession, and is all site welding installation, have following defects that
1. the support strength and shearing force of the bracket of two cross bars and brace collocation composition are insufficient, construction site for
Welding flaw detection can not accomplish requirement of experiment as a result, in the construction of certain heavy constructions, spacing between two supporting bridge columns
It is larger, so will cause the safety accidents such as tilt or even collapse there are security risk, when serious；
It 2. the site welding time is longer, material loss is larger, costly, cannot reuse, need to spend a large amount of people
The costs such as work, machinery (welding machine etc.), material, and overhead welding is relatively hazardous and insecure, and disassembly process is also extremely hazardous, and
Welding damages tube wall, and site welding not can guarantee welding requirements technique.
During bridge maintenance, it is often necessary in bridge bottom hung steel structure platform, when platform span is greater than 6m,
Generally take field fabrication.This kind of platform structure cannot be reused because the big transhipment of the scale of construction is inconvenient, at high cost, and waste is big.Bei Lei
Although this kind of fabricated construction convenient transportation of beam, this standard element cannot compress the scale of construction, and cost of wheeling is high.If by work
Platform Designing is at the field-installed truss of single rod piece, although cost of wheeling is low, on-site assembly is time-consuming.
Chinese Patent Application No. is 90222737.8, discloses a kind of extended position beam element structure, which passes through solution
Except certain rod ends are hingedly with some telescoping rods of setting, folded again after truss is become geometrically unstable system.Due to needing
It is hinged manually to release certain rod ends, or manually rod end is connected on node, to high-altitude or job engineering performance difficulty high up in the air.
Chinese Patent Application No. is 201620008878.4, discloses a kind of folding plane girder in longitudinal direction, the truss
Certain member designs at telescopic component, using hinged at rod node, do not need the rod piece of dismantling truss, directly control
The length of telescopic rod realizes that the folding of girder system is collapsed or is unfolded.Because of the telescoping member unbalance stress of truss, when telescopic rod not
In proportion when synchronization telescope, the expansion of each internode of truss can be made or folded asynchronous.
To solve the above-mentioned problems, a kind of easy-to-mount high stability supporting bridge of the applicant's earlier application is fixed
Frame comprising a cross tube, a sheer pole, three vertical bars, two braces, four connectors and four anchor ears, three etc.
The both ends of the vertical bar away from arrangement are fixedly connected with the cross tube and the sheer pole respectively and are formed two rectangular cavities, and two
The both ends of brace described in root are diagonally fixedly connected with two of two rectangular cavities respectively, both ends of the cross tube and described
The both ends of sheer pole are fixedly connected with a connector respectively, each connector and a corresponding anchor ear it
Between be bolted, the anchor ear is set in when in use on supporting bridge column.
The supporting bridge fixed frame during use, cooperates with bridge, is fixed on bridge by the fixation device at both ends
Liang Shang, when the size of truss is larger, installation anchor ear is possible to almost gap, so that there are certain difficulty for installation, due to height
Operation empty or high up in the air, this just brings great inconvenience to installation personnel, needs to improve.
In addition, the bridging of conventional stent mode connects all by the way of welding, welding scald can not be detected, high-altitude
Task difficulty is big, and time-consuming long, the material of welding cannot be recycled, and waste of material is serious；And welding also will cause steel branch
The secondary loss of support.
Therefore, how to solve the problems of the above-mentioned prior art becomes the direction of field technical staff effort.
