Description
Technical field
A kind of frock jig structure is the utility model is related to, more particularly to a kind of bridge steel box girder frock jig structure.
Background technology
Steel box-girder, is called ntitorque steel plate box-girder, is the common structure type of Large Span Bridges.It is commonly used in the larger bridge of span
Liang Shang.External form is as a chest therefore is called steel box-girder.Steel box-girder generally by top plate, bottom plate, web and diaphragm plate, midfeather and
Ribbed stiffener etc. is formed by connecting by all-welded mode.Wherein top plate is the orthotropic bridge being made of cover board and longitudinal stiffener
Panel.
Under the prior art, the jig structure of fixed steel box-girder is used to support, its structure is relatively simple, to steel box-girder thereon
Camber and linear and steel box-girder top plate, all there is certain negative effect for the welding of bottom plate, web and floor.
The content of the invention
In order to solve problem of the prior art, the utility model provides a kind of bridge steel box girder frock jig structure, its
Compared with existing frock moulding bed, there is simple installation, speed of application is fast, on the premise of ensureing that frame structure is stablized, materials phase
To less.
Technical solution is as follows used by the utility model：
A kind of bridge steel box girder frock jig structure, including buried pile pile, four rhizosphere of pile pile into one group of supporter,
Laterally three groups of three groups of longitudinal direction totally nine component cloth, is connected between the pile pile of every group of supporter solid by the channel steel bridging of right-angled intersection
It is fixed, I-steel load-bearing longeron is set at the top of the pile pile, is connected above the I-steel load-bearing longeron by supporting square tube
There is I-steel to distribute crossbeam, the box beam bottom of fixed steel box-girder is connected above the I-steel distribution crossbeam.
I-steel distributes between crossbeam and I-steel load-bearing longeron and is provided with support angle steel.
Support channel steel is provided between I-steel load-bearing longeron and pile pile.
The beneficial effect brought of technical solution that the utility model embodiment provides is：
A kind of bridge steel box girder frock jig structure of the utility model, its sturdy construction, stabilization, ensure steel case well
The camber of beam and linear and steel box-girder top plate, bottom plate, the welding performance of web and floor, compared with existing frock moulding bed,
With simple installation, speed of application is fast, and on the premise of ensureing that frame structure is stablized, materials are relatively fewer.
Brief description of the drawings
It is required in being described below to embodiment in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
Attached drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the utility model
Example is applied, for those of ordinary skill in the art, without creative efforts, can also be according to these attached drawings
Obtain other attached drawings.
Fig. 1 is a kind of cross-sectional configuration figure of bridge steel box girder frock jig structure of the utility model；
Fig. 2 is a kind of longitudinal plane structure figure of bridge steel box girder frock jig structure of the utility model；
Fig. 3 is the A portions structure enlargement diagram in Fig. 2.
Embodiment
It is new to this practicality below in conjunction with attached drawing to make the purpose of this utility model, technical solution and advantage clearer
Type embodiment is described in further detail.
Embodiment one
As shown in attached drawing 1-2, a kind of bridge steel box girder frock jig structure, including buried pile pile 1, pile pile 1 four
Rhizosphere is into one group of supporter, horizontal three groups of three groups of longitudinal directions totally nine component cloth, passes through right-angled intersection between the pile pile 1 of every group of supporter
The connection of channel steel bridging 2 fix, the top of the pile pile 1 sets I-steel load-bearing longeron 3, the I-steel load-bearing longeron
3 tops are connected with I-steel by supporting square tube 4 and distribute crossbeam 5, the 5 fixed steel box-girder of top connection of I-steel distribution crossbeam
6 box beam bottom.
As shown in Figure 3, it is provided with support angle steel 7 between I-steel distribution crossbeam 5 and I-steel load-bearing longeron 3.
Support channel steel 8 is provided between I-steel load-bearing longeron 3 and pile pile 1.
In the present embodiment, main bridge first sets up 100 meters long, wide 46 meters of tooling platforms two, the use of 6 mounting bracket of steel box-girder
609x14mm steel pipes are arranged.According to ground requirement for bearing capacity, 1 embedded depth of pile pile is 9m.Pile pile 1 is by edge to main bridge center cloth
It is 6m, 4m, 6m to put spacing.Three groups of supporters are arranged for campshed in the middle part of wherein main bridge, and every four are one group, are used on four sides between group
20b# channel steels are as bridging, and spacing is 6m between campshed.Along bridge to setting Two bors d's oeuveres 28b# I-steel on steel-pipe pile 1 as load-bearing
Longeron 3,200x200x10mm steel square tube is set on load-bearing longeron 3 as supporting square tube 4, supporting square tube 4 along bridge to spacing be 3m, it is horizontal
Bridge to spacing be 3m.Single 25b# I-steel is set on supporting square tube 4 as distribution crossbeam 5.To ensure the overall firm of support system
Degree and stability, to setting Two bors d's oeuveres 28b# I-steel between the laterally steel-pipe pile of 6 meters of spacing as strengthening supporting, its upper part sets steel side
Pipe is used to support direction across bridge distribution crossbeam.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modification, equivalent replacement, improvement and so on, should be included in the guarantor of the utility model
Within the scope of shield.
