Description
Technical field
The present invention relates to a kind of Wavelike steel webplate prestressed concrete combined box beam bridge annex, particularly relate to a kind of waveform diaphragm of corrugated steel web plate composite box girder bridge.
Background technology
Wavelike steel webplate prestressed concrete combined box beam bridge replaces concrete as a kind of new composite structure type of bridge of box girder web using Wavelike steel webplate.Under Eccentric Loading, on case beam, can make section produce constraint torsion warpage and play limit warped normal strain.For traditional concrete web case beam, because the web thickness of Wavelike steel webplate is thinning, in face, flexible rigidity is much little compared with top board, base plate, and the transverse frame effect limiting cross section deformation is decreased, in addition steel web longitudinal rigidity intersects, the distortion effect of this box-beam structure under Under Eccentric Loading can be made to strengthen to some extent, thus make warped normal strain compared with bending normal stresses, larger proportion may be reached, if do not cause enough attention in structure design, be disadvantageous to the normal operation of structure.
Reducing the effective measures of warped normal strain is limit distortion distortion by the lateral ties steel beam column of spaced set some or concrete diaphragm.In addition, diaphragm can improve effective torsional rigidity of case beam, is conducive to the cross direction profiles of load.In current engineering, the design of diaphragm mainly comprises two kinds, i.e. concrete diaphragm and steel diaphragm.But concrete diaphragm can increase the deadweight of structure itself greatly, and steel diaphragm is prevent warpage outside face from needing to weld a large amount of stiffening rib, adds the activity duration, and is connected with Wavelike steel webplate transport afterwards not very convenient.Therefore, research and development are a kind of stressed more reasonable, and the Wavelike steel webplate tabula that constructing operation is more easy constructs developing the construction of Wavelike steel webplate prestressed concrete combined bridge and promoting significant.
Summary of the invention
Main purpose of the present invention is, overcomes the defect that existing diaphragm exists, and provides a kind of waveform diaphragm of corrugated steel web plate composite box girder bridge, easy construction, thus be more suitable for practicality, and have the value in industry.
The object of the invention to solve the technical problems realizes by the following technical solutions.The waveform diaphragm of the corrugated steel web plate composite box girder bridge proposed according to the present invention, described Wavelike steel webplate is arranged between concrete roof and concrete floor, diaphragm is provided with between two adjacent Wavelike steel webplates, steel plate is fixed with in the Wavelike steel webplate position being provided with diaphragm
Described diaphragm is movably connected on steel plate.
Further, the waveform diaphragm of aforesaid corrugated steel web plate composite box girder bridge, steel plate has preformed hole, and corresponding with the preformed hole at diaphragm two ends, described diaphragm is fixed on steel plate by the preformed hole on diaphragm and the preformed hole on steel plate by bolt.
Further, the waveform diaphragm of aforesaid corrugated steel web plate composite box girder bridge, described diaphragm is groove and the protruding wavy shaped configuration arranged at equal intervals, described projection is an arcuate structure, distance between protruding arcuate structure two ends is 45cm ~ 55cm, forms the radian angle of 145 ° ~ 155 °; Groove forms an inside arcuate structure, distance between the arcuate structure two ends of groove is 45cm ~ 55cm, form the radian angle of 145 ° ~ 155 °, protruding and groove are controlled to ensure that in rational arc range diaphragm has stronger torsional rigidity, increases the service life.
Further, the waveform diaphragm of aforesaid corrugated steel web plate composite box girder bridge, two pieces of diaphragms are connected, and fix with the place's steel plate on Wavelike steel webplate.
Further, the waveform diaphragm of aforesaid corrugated steel web plate composite box girder bridge, between two pieces of connected diaphragms, groove is corresponding with groove, protruding corresponding with projection, groove is provided with preformed hole, when diaphragm is in precalculated position, by bolt, two pieces of diaphragms are fixed, strengthen fastness.
By technique scheme, the waveform diaphragm of corrugated steel web plate composite box girder bridge of the present invention at least has following advantages:
The waveform diaphragm of corrugated steel web plate composite box girder bridge of the present invention: compared with concrete diaphragm, greatly reduce dead load, resistance capacity to deformation strengthens; Compared with ordinary steel diaphragm, there is anti-enough outer unstability ability, without the need to welding stiffening rib, decreasing the procedure of diaphragm; Diaphragm of the present invention is flexibly connected with Wavelike steel webplate mutually by the steel plate be fixed on Wavelike steel webplate simultaneously, can be separated, and convenient transport, decreases site operation difficulty.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
