Description
Technical field
The utility model belongs to bridge construction technology field, and in particular to a kind of steel reinforced concrete combination portal structures.
Background technique
With the great-leap-forward development of railway construction in recent years, and due to the limitation of land used, newly built railway frequently with it is existing
Highway, the same or similar trend in railway line position, so that newly built railway becomes increasingly prevalent with intersecting for existing line.It is existing
When line is transformed, increase foreign body intrusion device such as on highway bridge, or when railroad bridge adds the equipment such as anti-throwing net, often
Need to create line or both wired construction overline structure across lower layer.When upper and lower level crossing elimination, often by land used and structure height
Limitation, conventional structure be often difficult to realize scissors crossing.Door type structure is combined using steel reinforced concrete at crossing elimination, not only may not be used
It is limited by land used, moreover it is possible to the work point being limited well suitable for structure height.For these reasons, steel reinforced concrete combination door type structure exists
It achieves and is more and more widely used in Existing railway promotion construction.
It is mostly busy trunk lines that steel reinforced concrete, which combines the both wired of gate-type construct trans, and can not be cut off traffic, and steel reinforced concrete combines
The girder steel of door type structure can be built in lifting construction, the place that concrete column can then allow in land used range in upper layer circuit
It makes, it is not only small to both wired operation interference in this way, and overline structure quickly can be built in construction period, shorten construction work
Phase saves construction cost.
Summary of the invention
The purpose of the utility model is to provide a kind of steel reinforced concretes to combine portal structures, has performance of concrete column confined low cost and girder steel concurrently
The advantage small to both wired interference easy for construction can be widely used for existing overbridge across busy trunk lines and high-speed rail route.
The technology employed by the present utility model is
A kind of steel reinforced concrete combination portal structures, it is characterised in that:
Steel box-girder including door shape, steel box-girder include the vertical pillar of crossbeam and crossbeam both ends lower part, crossbeam and vertical branch
Column is steel box, and vertical posts bottom is fixed to the pier top on pier stud basis by steel reinforced concrete binding site；
Steel reinforced concrete binding site is the steel and concrete structure that casting concrete is formed inside and outside pier stud basis pier top and vertical pillar；
Vertical posts bottom is preset with upper layer shape of the mouth as one speaks steel plate, and pier stud basis pier top is preset with lower layer's shape of the mouth as one speaks steel plate, upper layer shape of the mouth as one speaks steel plate and
Lower layer's shape of the mouth as one speaks steel plate is bonded up and down, is provided in the hollow range of shape of the mouth as one speaks steel plate and is extended respectively into vertical pillar up and down and pier stud base
Vertical middle part fashioned iron in plinth is provided with downward peripheral fashioned iron within the scope of shape of the mouth as one speaks steel plate frame.
Lower end is provided with vertical pillar in the middle part of the crossbeam of steel box-girder, which is fixed to pier by steel reinforced concrete binding site
The pier top of column foundation.
Horizontal regular reinforcement is evenly arranged outside the vertical pillar of steel reinforced concrete binding site, in concrete.
The steel chamber interior wall of vertical pillar is provided with vertical ribbed stiffener.
The steel box outer wall of vertical pillar is provided with weldering nail.
The utility model has the advantage that
The closed type steel box-girder that the utility model girder steel uses, integral hoisting construction, to the interference very little of both wired operations；
It is inserted into built performance of concrete column confined after steel box-girder lifting, then by forming whole gate-type in binding site casting concrete
Structure, constructing operation carries out in steel case and by pier stud, without setting up bracket in existing line range, it can be ensured that construction period was both
Wired operation security；This structural steel beam span can be adjusted with the practical land use situation of specific work point, if span is larger, steel
Beam can pass through steel plate and be bolted after segmented lifting, and the selection of pier stud position is then more flexible；The steel reinforced concrete of this structure combines
" rigid structure " form of concrete is wrapped up in using steel box-girder disposed outside weldering nail in position outside, does not use traditional " beam body → support → pier
The type of bridge of column " exempts the buying and mounting cost of support, also saves workload while saving the duration.
