In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
A kind of cement concrete slump divergence integrated measurer, comprise base, the perpendicular chi of cylinder is installed on base, the surveyor's staff sliding along the perpendicular chi of cylinder is installed on the perpendicular chi of cylinder, on described base, be provided with chute, described chute is circular along the limit of base, slide block is installed on chute, the perpendicular chi of cylinder is fixed on slide block under the drive of slide block along runner movement, described surveyor's staff is arranged on the perpendicular chi of cylinder by sleeve, on sleeve lining, be provided with one deck rubber layer, the inwall of rubber layer contacts with the perpendicular chi of cylinder;
Two parallel vulcanie sheets that can move along surveyor's staff are installed on described surveyor's staff, and the centre position of vulcanie sheet offers installs seam, and surveyor's staff is arranged on vulcanie sheet on surveyor's staff through the installation seam of two vulcanie sheets.
The utility model compared with prior art, has following technique effect:
Device of the present utility model has been realized the synchro measure of the slump and divergence, has removed the impact of experimental enviroment condition and the restriction in geographic position simultaneously, makes the measurement of Control Measures for Concrete Slump divergence be tending towards standardization, and measuring error reduces; Vertically circle chi can slide and can turn on base, can measure the divergence of different parts, not only simplified test operation, and improved the accuracy of location while measuring, device of the present utility model is easy to split and combination, has reduced storage area, simultaneously, part, if any wearing and tearing, is changed very convenient.
