Description
Technical field
The utility model belongs to technical field of bridge engineering, constructs more particularly, to a kind of movable type of prefabricated wide cut beam slab
Platform.
Background technology
With the continuous development of China's economy, Transportation Infrastructure Construction scale also constantly expands, and is used as and is held using beam slab
Bridge by load main body is increasing.Wherein precast beam due to can in advance non-construction area carry out batch production it is prefabricated,
It is separated with bridge foundation and infrastructure, concurrent construction, therefore has many advantages, such as that construction speed is fast, cost is relatively low, in bridge
Extensive use in beam engineering.For the small size beam slab of limited width, after needing multi-disc beam slab laterally to couple integrally per bridge beam,
The various loads of bridge floor are born jointly.Since perfect condition is not achieved in connection between beam slab, leads to local beam slab monolithic stress, cause
Beam body concrete and reinforcing bar, presstressed reinforcing steel enter the fatigue phase in advance, occur the crack that quantity differs, gradually losing carrying work(afterwards
Can, it eventually leads to beam slab and fractures, caves in, the serious accidents such as car crash may be caused, therefore, reinforcing prefabricated construction quality pipe
While reason, design department also begins to research and substitutes traditional small size beam slab using wide cut beam slab, and has become development trend.
The related request that authorities create " quality engineering " is built according to traffic base, beam slab is pre- in science of bridge building at present
System uses platform construction substantially, and construction personnel stands directly on construction etc. in framework of steel reinforcement or template, concrete and is contrary to before eliminating
The phenomenon of civilization, also ensure that construction quality and construction safety to a certain extent.Conventional platform is installed in beam-slab template
Afterwards, it erects stupefied or local template using the part of two rows of vertical frameworks to set up as the supporting point of platform, but there is each
The not high drawback of cumbersome, degree of safety is dismounted, especially in wide cut beam slab prefabricated construction, such platform is due to two rows of vertical frameworks
Spacing is excessive to be led to platform insufficient rigidity and sets up difficulty, or influences using effect.
China Patent No. CN205205677U discloses a kind of precast beam tensioning job platform, including four vertical and be in
The upright bar of square array is fixedly connected with the rectangular upper enclosure frame structure being made of horizontal cross bar between upright bar upper end and lower end
With rectangular lower enclosure frame structure, rectangular upper enclosure frame structure lower section is fixedly connected with two track supporting rods disposed in parallel, two rails
Vertically be fixedly connected with two cross tracks between road supporting rod, be equipped between two tracks support one with both parallel indulge
To track, transverse sliding mechanism is equipped between the both ends and cross track of long rails, in addition under the long rails
Portion is equipped with longitudinal sliding motion hoisting mechanism.
This job platform disclosed above is for having poured the beam slab end progress prestressed stretch-draw for completing concrete
Operation, a job platform can only fix the beam slab end at corresponding one, and when needs carry out tensioning to other precast beam
When operation, needs to reset job platform, thus increase the workload of engineering, reduce engineering efficiency.
