Description
Technical field
The utility model is related to a kind of corrugated steel web plate composite box girder bridge construction field, and in particular to one kind is used for connecting ripple
Shape steel web lower flange and box beam concrete base plate, a kind of combined Wavelike steel webplate base plate Shear connection key.
Background technology
Corrugated steel web reinforced concrete combined box beam structure is a kind of steel-concrete that current China is wideling popularize
Combining structure, its web for being mainly characterized by being instead of by intensity waveform steel higher conventional concrete box beam, wave mode steel abdomen
Connected by shear connector between plate and roof and floor.Due to Wavelike steel webplate have from heavy and light, shearing strength it is high, can prefabrication etc.
Feature, therefore it is more reasonable to greatly reduce dead load, structure stress, improves span of bridge, avoids conventional concrete
Box girder web problem of Cracking.
Shear connection key is most important position in box girder with corrugated steel webs.Wavelike steel webplate due to it, " imitate by accordion
Should ", most of vertical shear is assume responsibility for, and box beam roof and floor then undertakes curved pressure.Whether two kinds of materials can be good at connection
It is integrated, common resistance imposed load effect, it is necessary to by the effect of Shear connection key.At present, domestic and international Wavelike steel webplate case
Beam compared with frequently with shear connector connected mode mainly have two kinds：Baried type shear connector and edge of a wing type shear connector.
Embedded type shear connector is to be embedded in roof and floor Wavelike steel webplate in advance before roof and floor concrete construction, waits to mix
After the completion of solidifying soil is poured, so that Wavelike steel webplate is connected integral with roof and floor.The advantage of this kind of shear connector be simple structure,
Construction is the most economical, but has the disadvantage that shear connector connection more weak, integral working is poor.
Edge of a wing type shear connector is that lower edge welding steel on Wavelike steel webplate is formed into flange plate, is then welded on steel flange plate
A kind of shear connector form of different type steel is connect, its holistic resistant behavior is improved compared with embedded type shear connector, it is special
It is not the PBL shear connectors that opening steel plate is welded under flange plate, is the shear connector type of attachment that the current country is most frequently with.But it is big
Amount engineering practice finds, when this kind of shear connector form is used for box beam construction of bottom plates, because flange plate is located at shear connector top, base plate
