Description
Technical field
The utility model relates to the construction equipment of building bridge, relate in particular to bridge in soft base to the Bailey beam support of in-situ beam casting employing without buttress.
Background technology
Along with modern economy development at a high speed, the construction of rail transport is extremely urgent.In the construction of rail transport, cast-in-situ box girder is often adopted in the construction of bridge.Wherein, part simple supported box beam and continuous beam adopt full framing and steel pipe Bailey beam support to build.In prior art, disclose as 2011205160386 patents and utilize steel pipe Bailey beam rack construction in soft base, this Technology Need builds the steel pipe buttress by castinplace pile, steel pipe pile, has increased cost of production, has extended the duration, has strengthened difficulty of construction.Simultaneously, the Bailey beam in this technology is single layer structure, and when employing was constructed without the buttress technology, its bearing capacity can't meet the demands.
Summary of the invention
For problems of the prior art, the utility model provide a kind of in soft base to the double-deck Bailey beam support of in-situ beam casting employing without buttress, this Techniques For Reducing cost of production, shortened the duration, constructability guarantees safety in production.
In order to solve the deficiencies in the prior art, the technical solution adopted in the utility model is:
In a kind of soft base without the Bailey beam support of buttress, comprise the cushion cap with pier shaft, be provided with the steel pipe that the bottom is connected with described cushion cap on described pier shaft, the end of described steel pipe is provided with first crossbeam and the second cross beam that is parallel to each other, described steel pipe is connected with described cushion cap by the cushion cap built-in fitting, described steel pipe is by pier shaft built-in fitting and described pier shaft, be provided with bracing frame between described steel pipe, be provided with Bailey beam between described first crossbeam and second cross beam, be disposed with jack and template on described second cross beam.
Described Bailey beam is double-decker.
More than described Bailey beam at least 15 groups.
Support frame as described above is that the parallel and drift angle in two bases is to the triangular structure on top.
The spacing of each described cushion cap built-in fitting is a few shape reinforcing bars of 80-100mm.
The spacing of each described pier shaft built-in fitting is a few shape reinforcing bars of 80-100mm.
Described jack is more than at least 6.
Distance between each described jack is 1.0m.
The beneficial effects of the utility model are: first, the utility model has adopted to be installed built-in fitting and is connected with steel pipe on cushion cap, pier shaft, utilizing original cushion cap, pier shaft and steel pipe to form complete integral body has replaced needing in prior art to build buttress, reconstruct ground, save production cost, the duration shortens.The second, the utility model has been set up bracing frame between steel pipe, guaranteed between steel pipe stressed evenly, strengthened the stability of cast-in-place box beam bracket.The 3rd, the double-deck Bailey beam in the utility model can be decomposed the gravity that the jack of face from it applies, and the gravity of having avoided steel pipe can't bear template causes cast-in-situ box girder to cave in, and guarantees safety in production.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As Fig. 1, as shown in Figure 2, the utility model provides in a kind of soft base the Bailey beam support without buttress, comprise the cushion cap 1 that is provided with pier shaft 2, be provided with the steel pipe 4 that the bottom is connected with described cushion cap 1 on described pier shaft 2, the end of described steel pipe 4 is provided with the first crossbeam 7 and second cross beam 8 that is parallel to each other, described steel pipe 4 is connected with described cushion cap 1 by cushion cap built-in fitting 3, described steel pipe 4 is connected by pier shaft built-in fitting 5 connections with pier shaft, steel pipe 4 adopts the spiral steel plates and is equally distributed on that on cushion cap 1, cushion cap built-in fitting 3 welds usually; Between cushion cap built-in fitting 3, distance is between 2～3m, and built-in fitting 3 can adopt a few shape reinforcing bars of weld spacing 80～100mm on steel plate as shown in Figure 3.Be provided with bracing frame 6 between described steel pipe 4, support frame as described above 6 is that the parallel and drift angle in two bases is to the triangular structure on top.Can guarantee that like this steel pipe 4 is firm and stressed evenly.In manufacturing process, bracing frame 6 is channel-section steel and is welded into bridging.Be vertically arranged with 15 groups of above Bailey beams 9 between described first crossbeam 7 and second cross beam 8, described Bailey beam 9 is double-decker.It is equidistantly the two limb channel-section steels in 0.5～1 meter left and right that described first crossbeam 7 adopts i iron crossbeam, second cross beam 8 to adopt.Simultaneously, the spacing of the double-deck Bailey beam 9 of single group, quantity are determined by the weight of template and beam body.More firm for the structure that makes Bailey beam 9, can adopt the top-bottom chord of Bailey beam 9 to increase and strengthen chord member, brace and the local mode of strengthening of montant are constructed.Laterally set gradually the jack 10 more than at least 6 on described second cross beam 8.The position of jack 10 is mutually corresponding with the position of template 11 cross members.In reality, jack 10 is preferably selected the jackscrew of 16 tons.Placing box girder steel formwork 11 on jack 10 is adjusted the absolute altitude of template 11 by the height of adjusting jack 10, can reduce jack 10 so that the demoulding when needing form removal after concreting is completed.For the construction of Cast-in-situ Beam, use the mode of template 11 many, such as steel form, wooden form and plywood form are arranged, also have typified form and assembling combination template etc.The utility model has well solved the technical barrier at geological conditions defective sector cast-in-situ box girder beam type rack constructions such as mud, cross a river ditches, has saved cost.Its technology novel point is that direct of support stands on bridge bearing platform 1, does not need the independent support ground that carries out to process.A kind of job practices of novelty is provided for beam type rack construction Cast-in-situ Beam, has had good generalization.
Above embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is carried out limit; under the prerequisite that does not break away from the utility model design spirit; various distortion and transformation that those of ordinary skills make the utility model all should fall into the protection domain that claims of the present utility model are determined.
