Description
Technical field
The utility model relates to road surface job engineering technical field, more particularly, relates to a kind of adjustable integral type screed.
Background technology
Screed, as the core work device of asphalt paver, directly decides spreading quality and the functional performance of machine.At present, domestic and international ironing plate of asphalt spreader all adopts the rectangular box structure of Plate Welding, and bottom has been bolted Wear-resisting bottom plate.When pave hot-mix asphalt mixture time, the high-temperature that paver screed base plate will be heated to more than 130 DEG C, and screed casing upper part is in ambient temperature conditions.Because screed body structure upper and lower temperature difference is larger, the swell increment being in the lower part screed of high temperature is much larger than the swell increment of upper part screed being in low temperature, thus cause whole screed two ends to occur upwarping phenomenon, cause the decline of paving concrete pavement planeness thus, have a strong impact on the quality of construction of the highway.
In recent years, large width paver and modified asphalt mixture obtain application in Expressway Construction, and the flatness requirement of user to road construction is also more and more higher.For the construction of the high temperature material spreader such as increase and modified asphalt mixture of paver paving width, the heat distortion amount at screed two ends all can be caused to enlarge markedly.Existing screed thermal deformation suppressing way, mainly reserves heat distortion amount by screed casing and compensates thermal deformation, and this needs to change the physical dimension of screed, and small-sized due to reserved heat distortion amount, its processing and installation difficulty very large.And current most of ironing plate of asphalt spreader does not take effective thermal deformation suppressing way, work progress screed is heated generation deflection, has had a strong impact on the operation quality of paving concrete pavement.
