Paving thickness controlling method for grader

Abstract: PURPOSE:To construct a continuous pavement as flat as practicable and without interruption by making paving work so that the thickness lies within a reference range as specified CONSTITUTION:A vehicle 1 is equipped with a pair of height sensors 13, 14, an inclination sensor 15, and a calculating device 30 A guide sensor 19 is mounted on a screed 5 supported by a leveling arm 6, which rotates up and down round a supporting shaft 7 as fulcrum This guide sensor 19 moves along the reference line 25 consisting of curb stones etc, and a pivot cylinder 8 moving the supporting shaft 7 up and down is controlled so that the asphalt mix material is laid and graded while the screed 5 is kept with a certain level difference to the reference line 25 The guide sensor 19 is moved up and down by a vertical motion device 10 relative to the screed 5 The calculating device 30 calculates the paving thickness on the basis of the results from measuring made by the height sensors 13, 14 and inclination sensor 15, also calculates the difference of the mean paved thickness from the target thickness, operates the vertical motion device 10 on the basis of the difference obtained, and moves the guide sensor 19 up and down

Telescopic front retaining plate device of screed

Abstract: The utility model belongs to the technical field of pavement construction machinery, and particularly relates to a front retaining plate device of a paver screed. The telescopic front retaining plate device of the screed comprises two connection plates, a slideway, a sliding rod, a rib plate, a retaining plate and a scraper, wherein the two connection plates are welded on the slideway to form a fixed slideway; the fixed slideway is mounted on a screed suspender through the connection plates; the slide rod is welded on the retaining plate and is inserted into the slideway to form a movable support; the rib plate is welded on the retaining plate to form a telescopic retaining plate; the scraper is mounted on the retaining plate. The device can conveniently and quickly realize stepless regulation on retaining width along with the movement of a screed telescopic mechanism so as to guarantee the good working quality and high efficiency of a paver while reducing the labor intensity of constructors.

Apparatus for feeding and distrubuting concrete in slipforms

Abstract: An apparatus for delivering and distributing concrete along a surface, characterized by a sliding formwork armature extending transversely across the surface and being mounted for a longitudinal movement relative to said surface, a transverse region mounted thereon. reinforcement for smoothing the concrete on said surface in the desired surface configuration, and means mounted in said reinforcement in front of said screed for a continuous movement along the transverse length thereof adapted to distribute and mix the concrete before its smoothing by said aforementioned. reglon (Machine-translation by Google Translate, not legally binding)

Outer wall compound heat preservation board and parapet heat preservation mounting structure

Abstract: The utility model discloses an outer wall compound heat preservation board and corner heat preservation mounting structure This composite insulation board includes from last to down or the panel layer, heat preservation and the cement mortar screed -coat that set gradually to the right side from a left side, the heat preservation passes through the binder to be fixed on the cement mortar screed -coat, reentrant corner department in the corner is equipped with the composite insulation board that two mutual concatenations formed, is equipped with the clearance between two composite insulation board, composite insulation board and the laminating installation of corner surface, place the filler in the clearance, the top of filler paints that the one deck is sealed glues, and external corner department in the corner is equipped with the right angle composite insulation board the same with the corner angle, right angle composite insulation board's panel layer is aluminum plate, and the aluminum plate cladding is on whole right angle composite insulation board's heat preservation The utility model discloses have good resistant marquis's nature, waterproof nature, gas tightness and security, mounting structure is firm, is difficult for droing, can satisfy 65% energy conservation design requirement, and construction and installation is convenient, has shortened building cycle

Screed camber regulating device and paver with same

Abstract: The utility model provides a screed camber regulating device and a paver with the same. The screed camber regulating device comprises a regulating mechanism, an angle detecting device and a control device, wherein the regulating mechanism is flexibly connected with a first screed (3) and a second screed (4) of the paver; the angle detecting device is used for detecting an included angle, which is taken as a camber angle, between opposite side walls of the first screed (3) and the second screed (4); and the control device is respectively connected with the angle detecting device and the regulating mechanism, comprises a storing unit for presetting an original camber angle, and is used for regulating the camber angle according to a comparison result of the camber angle and the initial camber angle. The screed camber regulating device and the paver provided by the model can be used for improving the camber regulating accuracy and reducing the manual operation strength.
