Background technology
At present, along with the develop rapidly of China's expressway construction, being connected to each other between each speedway, intercommunication cross-line bridge engineering increase relatively, how to guarantee that existing line is current, and what guarantee again bridge construction is a new difficult problem of bridge construction smoothly.Stride in China that existing bridge on highway is general all to adopt special-purpose equipment for bridge construction, but when the construction of occupation bridge construction equipment stride several when less, the construction cost height, the duration is longer.
Summary of the invention
The purpose of this utility model provides a kind of existing bridge on highway that is applicable to stride, and existing bridge heavy traffic, can't adopt traditional Full space support construction or hang upside down the template suspension bracket because headroom limits the deck type that can't adopt the Hanging Basket cantilever construction, this hanger structure is simple, easy to operate, accelerating construction progress, reducing construction cost there are remarkable result.
The technical scheme that its technical problem that solves the utility model adopts is: deck type reversal of the natural order of things template suspension bracket, which comprises at least upright post system and deck type reversal of the natural order of things hanger system, it is characterized in that: the both sides of bridge pier shaft all are fixed with upright post system, the upright post system top cross-over connection of both sides has deck type reversal of the natural order of things hanger system, hangs by deck type reversal of the natural order of things hanger system and connects the suspension rod distribution beam that bridge is constructed.
Described upright post system mainly comprises upright post basic, steel pipe post, steel pipe lateral, laterally connects anchor ear and stake top distribution beam, be fixed with some steel pipe posts on the upright post basic, be interconnected to integral body by the steel pipe lateral between a plurality of steel pipe posts, steel pipe post links to each other with pier shaft by laterally connecting anchor ear, the top of steel pipe post is fixed with a top distribution beam, supports by the deck type reversal of the natural order of things hanger system of stake top distribution beam to top.
Described deck type reversal of the natural order of things hanger system comprises that vertical bridge is to Bailey beam, the direction across bridge Bailey beam, Bei Lei top distribution beam, suspension rod, the spherical backing plate of YGD, the direction across bridge Bailey beam is fixed on the stake top distribution beam of upright post system, the back position of direction across bridge Bailey beam is fixed with Bei Lei top distribution beam, vertical bridge is separately fixed on the shellfish thunder top distribution beam on upright post system top, the pier shaft left and right sides to the two ends, the left and right sides of Bailey beam, left and right sides upright post system is connected to become an overall structure, vertical bridge hangs by some suspension rods to the Bailey beam bottom and is connected to the suspension rod distribution beam, and the junction of suspension rod and suspension rod distribution beam is connected with the spherical backing plate of YGD.
Described suspension rod is finish rolling deformed bar.
Described suspension rod distribution beam is divided on the suspension rod distribution beam under the distribution beam and suspension rod, the suspension rod distribution beam adopts the double flute steel up and down, the double flute steel of suspension rod distribution beam is welded into suspension rod distribution beam integral body by junction plate up and down, and the distribution beam bottom increases the spherical backing plate of YGD under distribution beam top and suspension rod on the suspension rod.
The beneficial effects of the utility model are: this device is a kind of novel existing bridge construction device of striding, this device is under the condition that should not adopt the occupation bridge construction equipment, need not to arrange full framing at existing bridge, construct by setting up upright post system and deck type reversal of the natural order of things hanger system, do not change existing line special bus flow, and the whole system member all can have enough to meet the need use, to have remarkable result to reducing construction cost, accelerating construction progress, the construction that can be similar bridge provides helpful reference.

The specific embodiment
Embodiment 1
This deck type reversal of the natural order of things template suspension bracket mainly is made of upright post system and deck type reversal of the natural order of things hanger system.
The both sides of bridge pier shaft all are fixed with upright post system, and the upright post system top cross-over connection of both sides has deck type reversal of the natural order of things hanger system, hang by deck type reversal of the natural order of things hanger system and connect suspension rod distribution beam 11, carry out the construction of bridge by suspension rod distribution beam 11 again.
Embodiment 2
Shown in the elevation of this deck type of Fig. 1 reversal of the natural order of things template suspension bracket, upright post system mainly comprises: upright post basic 1, steel pipe post 2, steel pipe lateral 3, laterally connect anchor ear 4 and stake top distribution beam 5.
Be fixed with some steel pipe posts 2 on the upright post basic 1, be interconnected to integral body by steel pipe lateral 3 between a plurality of steel pipe posts 2, steel pipe post 2 links to each other with pier shaft by laterally connecting anchor ear 4, to guarantee the resistance to overturning of steel pipe post; The top of steel pipe post 2 is fixed with a top distribution beam 5, and the deck type reversal of the natural order of things hanger system by 5 pairs of tops of distribution beam, stake top supports.The both sides of pier shaft are distributed with upright post system, and the upright post system structure of both sides is identical.
Embodiment 3
As shown in Figure 1 and Figure 2, the reversal of the natural order of things of the deck type in above-described embodiment hanger system comprises: vertical bridge is to Bailey beam 6, direction across bridge Bailey beam 7, Bei Lei top distribution beam 8, suspension rod 9, the spherical backing plate 10 of YGD.
Direction across bridge Bailey beam 7 is fixed on the stake top distribution beam 5 of upright post system, the back position of direction across bridge Bailey beam 7 is fixed with Bei Lei top distribution beam 8, vertical bridge is separately fixed on the shellfish thunder top distribution beam 8 on upright post system top, the pier shaft left and right sides to the two ends, the left and right sides of Bailey beam 6, left and right sides upright post system is connected to become an overall structure, vertical bridge hangs by some suspension rods 9 to Bailey beam 6 bottoms and is connected to suspension rod distribution beam 11, and suspension rod 9 is connected with the spherical backing plate 10 of YGD with the junction of suspension rod distribution beam 11.
After upright post system and the installation of deck type reversal of the natural order of things hanger system, adopt the weight of beam body weight 120% that it is carried out precompressed, eliminate the nonelastic deformation of deck type reversal of the natural order of things template hanger system, in order to camber is set in advance, guarantee that bottom elevation meets designing requirement; After precompressed is finished, colligation case beam steel, build box beam concrete, designing requirement post-stress to be reached.
After construction is finished, remove deck type reversal of the natural order of things template hanger system, follow the principle of " first dress then tear the tearing open first of rear dress open " and carry out.Remove successively deck type reversal of the natural order of things template hanger system, upright post system.
