Description
Technical field
The present invention relates to road surface job engineering technical field, more particularly, it relates to a kind of adjustable integral type screed.
Background technology
Screed, as the core work device of asphalt-spreader, directly decides spreading quality and the serviceability of machine.
At present, domestic and international ironing plate of asphalt spreader all uses the rectangular box structure of Plate Welding, and bottom has been bolted
Wear-resisting bottom plate.When pave hot-mix asphalt mixture when, paver screed base plate will be heated to the high-temperature of more than 130 DEG C,
And it is partially in ambient temperature conditions on screed casing.It owing to screed body structure upper and lower temperature difference is relatively big, is in high temperature
The swell increment of lower part screed much larger than the swell increment of upper part screed being in low temperature, thus cause entirely pressing
Plate two ends occur upwarping phenomenon, thus cause the decline of paving concrete pavement flatness, have had a strong impact on the quality of construction of the highway.
In recent years, big width paver and modified asphalt mixture are applied in Expressway Construction, and user
Also more and more higher to the flatness requirement of road construction.Increase and modified asphalt mixture for paver paving width
Deng the construction of high temperature material spreader, the heat distortion amount at screed two ends all can be caused to significantly increase.Existing screed heat becomes
Shape suppresses way, mainly reserves heat distortion amount by screed casing and compensates thermal deformation, and this needs to change ironing
The physical dimension of plate, and small-sized due to reserved heat distortion amount, its processing and installation difficulty are very big.And it is current
Most of ironing plate of asphalt spreader do not take effective thermal deformation suppressing way, and work progress screed is heated and is deformed
Amount, has had a strong impact on the operation quality of paving concrete pavement.
