Description
Technical field
The present invention relates to the fabricated device of corrugated steel web box beam, relate more specifically to a kind of suitable for different structure ginseng
Number, particularly for the prefab-form system of many case corrugated steel web box beams that broaden.
Background technology
The girder of corrugated steel web bridge is made up of concrete roof and floor and corrugated steel web.As shown in figure 1, it includes mixing
Solidifying soil top board 3, concrete floor 2 and corrugated steel web 1.At present, Wavelike steel webplate combined bridge has been obtained quickly at home
Development.The conventional construction method of the type bridge is raft support method, incremental launching method, cantilever-construction etc., raft support method and
Incremental launching method is respectively adapted to small across footpath bridge, uiform section Medium Span bridge construction, and cantilever construction rule is suitable to Large Span Bridges
Construction.
In recent years since, precast segment assembling method with its speed of application it is fast, quality is easily controllable, good environmental protection the advantages of
It is widely used, the technique is applied into Wavelike steel webplate bridge construction will also become a reality.Short segment matching is prefabricated
Technique is a kind of advanced construction technology, has main steps that and for bridge more long to be divided into short segment, and short-term mould is used in factory
Transport to spelling at bridge location is mounted to bridge after plate is prefabricated；Its realization it is critical only that and be obtained by the control to sections physical dimension
Desired planform is obtained, wherein good template system is important guarantee.In actual bridge structure, structure type is various more
Sample, even if in same bridge block, there is also the change of structural parameters, such as width of box beam, the size of box beam inside chamber.
The corrugated steel web bridge structure difference maximum with common Prestressed Concrete Bridges structure is web, is existed in Specific construction
Following problem：
(1) corrugated steel web beam uses corrugated steel because of web, without setting up web side template casting concrete；(2) ripple
Line steel web needs the enough fixations of intensity during casting concrete, vibrated concrete, to ensure the precision after shaping；
(3) corrugated steel web and concrete slab boundary position are, it is necessary to extra template.
Meanwhile, becoming broad box girder typically has following characteristics；
(1) contours profiles are constant, i.e., have identical geometric shape inside and outside box beam at chamfering；
(2) top board width, baseplate width change.
Therefore, for different structure type, especially many chamber types that broaden in wide cut bridge, need to research and develop a set of work(
Complete, easy construction and the matching prefab-form system of Wavelike steel webplate sections can be suitable to.
