Abstract
The utility model discloses an elongated back pressure bracket. The elongated back pressure bracket is characterized by comprising a bracket upper part and a bracket lower part, between which a connecting plate is arranged. Compared with the prior art, the elongated back pressure bracket has the advantages that the bracket is constructed through two parts of structures, the bracket lower part is firstly welded before a steel boxed cofferdam is released to the lowest tidal water level, and then the bracket upper part is welded, so that the influence of fluctuated tidal water on construction can be avoided.
Description
[technical field]
The utility model relates to a kind of new structure that is used for deep water steel box work progress suspention steel box and anti-steel box come-up, specifically relates to a kind of extended type back-pressure bracket.
[background technology]
Along with Chinese economic development, bridge constructions such as over strait, rivers grand bridge, bridge are also more and more.The deep water cushion cap adopts the construction of steel box more in the bridge construction at present.The structure of load-bearing bracket is generally simple shaped steel or steel plate, and welding procedure is used to bear the weight of steel box and part-structure concrete on the skeleton shaped steel of box bed die.But because the influence that impacted by the fluctuation tidal water flow, and cushion cap is many below the neap water level in the design, and the welding of bracket can't be carried out in water.
[utility model content]
The utility model is in order to solve above-mentioned deficiency, a kind of extended type back-pressure bracket to be provided.
The above-mentioned purpose of the utility model realizes through following technical scheme: a kind of extended type back-pressure bracket is characterized in that: comprise bracket top and bracket bottom, said bracket top and bracket bottom weld together through junction plate.
The construction sequence of the utility model: at first transfer before below the neap water level at the steel box; Accomplish the welding procedure of bracket substructure; When transferring to design elevation; Weld the superstructure of bracket again, and final welding bracket and pile foundation steel casing, it is stressed by the power system conversion of suspension system to the back-pressure bracket to accomplish the steel box.
The utility model advantage compared with prior art is: the bracket of the utility model can the branch two-part structure be constructed; Transfer to the neap water level welding bracket bottom earlier at the steel box; After weld bracket top again, avoid receiving the fluctuation tidal water flow to impact and influence construction.

Fig. 1 is the structural representation of the utility model;
Fig. 2 is the utility model construction side elevational view;
Fig. 3 is the utility model construction front elevation view.
In the accompanying drawing, 1-pile foundation steel casing; 2-bed die skeleton shaped steel; 3-bracket top; The 4-junction plate; 5-bracket bottom; 6-front triangle link plate; 7-side triangle link plate.
[specific embodiment]
Below in conjunction with accompanying drawing the utility model is further detailed:
As shown in Figure 1, a kind of extended type back-pressure bracket is characterized in that: comprise bracket top 3 and bracket bottom 5, said bracket top 3 welds together through junction plate 4 with bracket bottom 5.
Like Fig. 2, shown in 3; The extended type back-pressure bracket of the utility model; After accomplishing steel box base plate assembly unit welding procedure; According to construction drawing blanking processing each structure semiproduct (water logging there is not the steel box degree of depth to carry out blanking to bracket bottom 5 length according to neap water level trend, and bracket top 3 length are carried out blanking according to concrete back cover end face absolute altitude).At first welding procedure bracket bottom 5, front triangle link plate 6, side triangle link plate 7 on bed die skeleton shaped steel 2; Need measure the verticality of bracket bottom 5 during welding bracket bottom 5; Measure and weld after qualified; On inspection weldquality qualified after, transfer steel box base plate and assembly unit steel box side plate, can transfer the steel box to design elevation after accomplishing.Transfer to accomplish and afterwards steel box plan-position and absolute altitude measurement are checked, qualified back is carried out temporary fixed on pile foundation steel casing 1.After accomplishing above-mentioned work, can welding procedure bracket top 3, junction plate 4.When bracket top 3 is installed; The panel that guarantees bracket top 3 is close to pile foundation steel casing 1; Should guarantee the dead in line of bracket top 3 and bracket bottom 5 simultaneously; Carry out the welding of bracket top 3 and pile foundation steel casing 1 and the butt welding of bracket top 3 and bracket bottom 5 after carrying out above work, after accomplishing junction plate 4 is close to bracket top 3 and welds with bracket bottom 5 web faces.Carry out once comprehensively weldquality inspection after above-mentioned whole welding procedure is accomplished, can carry out the concrete back cover of steel box and the construction of cushion cap operation after the passed examination.
What should explain at last is: the foregoing description only be for explain clearly that the utility model does for example; And be not the qualification to embodiment; Those of ordinary skill for affiliated field; On the basis of above-mentioned explanation, can also make other multi-form variation or change, need not here also can't give to all embodiments exhaustive, and the conspicuous variation of being amplified out thus or the change still be among the protection domain of the utility model.
