Description
Technical field
The present invention relates to a kind of corrugated steel web plate composite box girder bridge construction field is and in particular to a kind of be used for connecting waveform steel
Web lower flange and box beam concrete base plate, a kind of combined Wavelike steel webplate base plate Shear connection key and construction method.
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, it is mainly characterized by being instead of the web of conventional concrete box beam, wave mode steel abdomen by the higher waveform steel of intensity
Pass through shearing bonded between plate and roof and floor.Due to Wavelike steel webplate have from heavy and light, shearing strength high, can prefabrication etc.
Feature, it is more reasonable therefore 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 ", assume responsibility for most of vertical shear, and box beam roof and floor then undertakes curved pressure.Whether bi-material can be good at connecting
It is integrated, common opposing imposed load effect is it is necessary to rely on 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 before roof and floor concrete construction, Wavelike steel webplate to be embedded in roof and floor in advance, waits to mix
After the completion of solidifying soil pours so that Wavelike steel webplate be connected with roof and floor integral.The advantage of this kind of shear connector be simple structure,
Construction is the most economical, but shortcoming is shearing, and bonded more weakness, integral working are poor.
Edge of a wing type shear connector is that lower edge welding steel on Wavelike steel webplate is formed flange plate, then welds on steel flange plate
Connect a kind of shear connector form of dissimilar steel, its holistic resistant behavior is improved compared with embedded type shear connector, special
It is not the PBL shear connector welding opening steel plate under flange plate, be the domestic at present shear connector type of attachment being 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
After formwork erection, due to the stop of lower flange steel plate, concreting, difficulty of vibrating, because concrete gravity leads to steel reinforced concrete junction
Leakiness, has had a strong impact on structure durability.
Content of the invention
