Description
Technical field
The present invention relates to technical field of bridge engineering, more particularly to a kind of moulding bed device of segmentation dismounting.
Background technique
The structural schematic diagram of Support Method assembly Steel Bridge as shown in Figure 1, Support Method assembly girder steel are generally used in steel bridge
Several support posts 12 are set at beam stress node, concentrate the load for bearing Steel Bridge 11, after Steel Bridge 11 is all assembled again
Remove the support post 12 of lower part.It takes the method to construct, needs when assembled Steel Bridge 11 scene that support post 12 is first set, then
The associated components of Steel Bridge 11 are supported using support post 12 from bottom to up and carry out assembly.
When carrying out assembled on cross a river rack platform 13, if according to Support Method assembly Steel Bridge, Steel Bridge 11 will be direct
It drops down above support post 12, each 12 stress of support post is different, it is difficult to control each 12 uniform settlement of support post, finally lead
It causes the whole unbalance stress of Steel Bridge 11 and deforms, more uncertainty occur, can not ensure safely, if taking corresponding add
Gu then resource input is excessive for measure.Meanwhile the lower bridge floor of arch bridge is lower arcuate surface, and the method is taken to be difficult to ensure under Steel Bridge
The arc assembly requirement of bridge floor.
Summary of the invention
A kind of moulding bed device for being designed to provide segmentation dismounting of invention, the segmentation that can quickly finish moulding bed device are torn open
Dress, the weight of bridge are evenly distributed on entire moulding bed device, so that each column uniformly bears weight, control column uniformly sinks
Drop, avoids bridge from deforming because of local pressure.
Invent used by technical solution be it is a kind of segmentation dismounting moulding bed device, including by several moulding bed unit splits and
At moulding bed, the moulding bed unit includes the support column that top surface and at least one are used to support top surface, all moulding bed lists
The two ends capable assembling connection of the top surface of member, the top surface of the adjacent moulding bed unit piece together supporting surface, the supporting surface and to
The bottom surface of supporting bridge matches.
It advanced optimizing, the top surface is arc shape, and the top surface of all moulding bed units pieces together curved support face,
The curved support face and the bridge bottom surface of arch shape to be supported match.
It advanced optimizes, the moulding bed unit includes at least two vertical support columns for being used to support top surface, adjacent described
It is connected between support column by reinforcing rod head and the tail.
It advanced optimizes, the support column and top surface are all made of I-steel building.
Advantageous effect of the invention: can be segmented the installation for carrying out moulding bed device, realize the good moulding bed device of quick assembling, each
Top surface is arranged in the support column portion of moulding bed unit, and the top surface of all moulding bed units pieces together a complete supporting surface, entire bridge
The weight of beam is undertaken by entire supporting surface, so that the uniform force of each support column, each support column is uniformly settled, even if preceding
Certain sedimentation has occurred in the construction section in face, behind can also moderately be adjusted according to the sedimentation of front, will not be heavy because of support column
The case where drop unevenly causes the bridge of top local pressure occur and deform, the safety and stability of Steel Bridge obtains when assembled
To greatly improving, meanwhile, segmentation installation.
Detailed description of the invention
Invention is further illustrated with embodiment with reference to the accompanying drawing.
Fig. 1 is the structural schematic diagram of Support Method assembly Steel Bridge；
Fig. 2 is the structural representation of the moulding bed device of segmentation dismounting of the invention；
Fig. 3 is the structural schematic diagram of moulding bed unit.
Specific embodiment
The moulding bed device of segmentation dismounting as shown in Figures 2 and 3, including the moulding bed being put together by several moulding bed units,
Moulding bed unit 2 includes the support column 22 that top surface 21 and at least one are used to support top surface 21, the top surface 21 of all moulding bed units 2
The connection of two ends capable assembling, 21 split of top surface of adjacent moulding bed unit 2 forms supporting surface, supporting surface and bridge to be supported 3
Bottom surface matches.Support column 22 and top surface 21 are all made of the building of I-shaped Steel Bridge.
Moulding bed is put together by several each moulding bed units 2, can quickly finish the assembly of moulding bed, all 21 head and the tail of top surface
It is spliced into a complete supporting surface, the weight of bridge 3 is born by entire supporting surface, so that the support column 22 of support top surface 2 is equal
Even stress, thus 22 uniform settlement of support column, will not be settled because of support column 22 it is uneven and lead to that local pressure occurs in bridge 3 and
The case where deformation.
Top surface 21 is arc shape, and the top surface 21 of all moulding bed units 2 pieces together arc lower arcuate surface shape support face, arc
3 bottom surface of bridge of supporting surface and arch shape to be supported matches.
When the bridge of building is for arch bridge, the lower bridge floor of arch bridge is lower arcuate surface, conventional Support Method assembly Steel Bridge
It is difficult to ensure that the assembled of lower arcuate surface requires, in order to meet the requirement that the lower bridge floor of arch bridge is lower arcuate surface, by top surface 21
Certain arc shape is manufactured into, all top surfaces 21 piece together the supporting surface of the arch shape of the cooperation of one and lower arcuate surface, support
Face and arch bottom surface are consistent, and can be very good the assembled requirement for completing lower arcuate surface.
Moulding bed unit 2 includes at least two vertical support columns 22 for being used to support top surface 21, is led between adjacent supports column 22
Reinforcing rod 4 is crossed to connect from beginning to end.
It when supporting the span of top surface 21 bigger, needs to be supported by more vertical support columns 22, to improve support column 22
Stability and intensity, connected from beginning to end by reinforcing rod 4 between adjacent supports column 22, be built into one stable " triangle "
Shape.
Certainly, invention is not limited to above embodiment, and those skilled in the art are without prejudice to spirit
Under the premise of can also make equivalent deformation or replacement, these equivalent variation or replacement are all contained in the claim of this application and are limited
In fixed range.
