Description
Technical field
The present invention relates to technical field of bridge engineering, more particularly, to a kind of corrugated steel web combination PC bridges and its apply
Work method.
Background technology
PC bridges are the conventional designs in existing highway bridge, have many advantages, such as that intensity is high.Existing bridge requirement girder is cut
Face should be light and handy, streamlined, mitigates dead weight with this, reduces windage, construction is easier, and cost is more economical.
Develop with the adjustment of China's economy, traditional PC Bridge Designs are widely used, real material dosage and
Construction period comprehensively understands the advantage of this new construction and its practicability in Short/Medium Span Bridge.
But there are still deficiencies during construction and use for Wavelike steel webplate bridge prefabricated at present：Two train wave shapes
Steel web is separated from each other, and does not form entirety, this not only bad for local pressure, affect Wavelike steel webplate bending resistance, it is antitorque,
The rigidity of shearing resistance, and be due to insufficient rigidity in construction, self stability is poor, needs more stent to maintain waveform steel abdomen
The stabilization of plate, this constrains Wavelike steel webplate precast bridge competitiveness in urban construction significantly；Existing waveform steel abdomen simultaneously
Slab bridge Liangqi concrete roof and concrete box girder bottom plate needed again after the completion of man-hour requirement installation form rack construction is applied by
These falseworks disassemble, this not only increases construction cost but also extends construction period.
Therefore how to solve that Wavelike steel webplate bridge integrity is poor, cause the bending resistance, antitorque and shearing resistance of Wavelike steel webplate
Rigidity reduces, and so as to cause stability difference and needs to be added to using more Wavelike steel webplate, long construction period construction cost
For those skilled in the art's urgent problem to be solved.
