Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-3 is please referred to, the present invention provides a kind of technical solution: across the operation platform closed up in a kind of continuous rigid frame bridge,
Including bottom plate 1, bottom plate 1 is the steel plate with a thickness of 4cm, and length is greater than closure segment and constructs length 3 to 4m, and width is greater than closure segment master
For beam width 1 to 2m, side plate 2 is the steel plate with a thickness of 3cm, and totally two pieces, positioned at the two sides in width of main beam direction, baffle 3 is thickness
For the steel plate of 3cm, totally four pieces, positioned at the surrounding of bottom plate 1, placed along girder cross-sectional direction, the top of bottom plate 1 is provided with support
9, supporting 9 quantity is 24 pieces, and it is 10cm, the square bracing members with a thickness of 2cm that support 9, which is side length, is welded on bottom plate 1
On, angle steel 4 with holes is fixedly connected with by screw rod 5 on bottom plate 1, bottom plate 1 is fixedly connected with side plate 2 and gear by angle steel 4 with holes
Plate 3, the top of bottom plate 1 are provided with fining twisted steel 6, and the quantity of fining twisted steel 6 is four and is divided into two groups, two of every group
It is arranged with cantilever beam 10 to be closed up between fining twisted steel 6, is provided with headblock between cantilever beam 10 and jack 7 to be closed up
8, the surface of fining twisted steel 6 and be located at cantilever beam 10 to be closed up top be arranged with jack 7.
Detailed process when work is as follows:
First, in closure construction the last week, bottom plate 1, side plate 2 and baffle 3 are produced in advance, in the position for needing to penetrate screw rod 5
Reserving hole is set, and is properly saved after the assay was approved.
Second, when cantilever beam cradle construction, leaves the hole for wearing fining twisted steel 6 in advance, to concreting of cantilever beton to should be closed
After holding together the position of section construction, Hanging Basket is removed.
Third places headblock 8 and jack 7 on girder, by fining twisted steel 6 by wearing under jack 7, and transfers to
Minimum point.
4th, on ground, bottom plate 1 and side plate 2 are linked together by angle steel 4 with holes, screw rod 5.
5th, by fining twisted steel 6 and 1 firm welding of bottom plate, then baffle 3 is installed, if bridge height is not more than 20m,
This step can be completed on ground, if bridge height is greater than 20m, need to lift bottom plate and side plate by ladder or high-altitude operation vehicle
Suitable height is risen to, then carries out welding and the installation of baffle 3.
6th, entire operation platform is promoted by jack 7, after reaching the height that can be constructed, starts binding and closes up
Reinforcing bar, installation template and the casting concrete of section.
7th, after the completion of closure segment construction, form removal will be hung under operation platform with jack 7, then remove baffle
3, it cuts fining twisted steel 6, remove side plate 2 and bottom plate 1.
In conclusion across the operation platform closed up in the continuous rigid frame bridge, pass through bottom plate 1, side plate 2, baffle 3 and with angle of spot hole
The components such as steel 4 are used cooperatively, and can be very good to guarantee to reinforce the safety of operator across the construction quality closed up in bridge,
And the whole of operating platform is promoted and is declined, and greatly saves the construction time, and all kinds of steel plates for forming operating platform can spirit
Assembling and dismounting living, it is reusable, have good economic benefit, avoid due to construction error it is larger caused by bridge
Integral linear and aesthetics be affected.
