Abstract
The present invention is one kind of concrete slump instrument for detecting the performance of newly stirred concrete. One circular metal disc is set on one electronic scale with quadrangular casing and one cylinder with greater lower end diameter is connected, and the cylinder is filled with newly stirred concrete with the flatted upper end and weighed. The cylinder is then raised to separate from the electronic scale to let concrete spread to the disc and outflow concrete falling into the annular container support by the scale. The concrete in the disc is weighed and the ratio between the weight flowed into the annular container and the total concrete weight is calculated with the calculator in the scale. The ratio is used to express the slump of the newly stirred concrete. The present invention may be used widely in detecting the performance of great slump in concrete test and construction.
Description
Affiliated technical field
The present invention relates to a kind of surveying instrument of fresh concrete, particularly a kind of concrete slump instrument that detects the fresh concrete workability that is applicable to.
Background technology
At present, in concrete test and work progress, slump cone commonly used is measured the workability of fresh concrete, this method troublesome poeration, time-consuming, artificial operation factors influences measurement data easily, when particularly measuring the concrete slump of super mobility, can not accurately reflect concrete workability.
Summary of the invention
Measure the not accurate enough drawback of high slump concrete in order to overcome slump cone, the invention provides a kind of easy and simple to handlely, numeral shows, can measure the slump instrument of workability of concrete accurately.
Technical scheme of the present invention is: the electronic scales 5 that the four prisms cylinder shell is arranged, a rosette 10 is placed in the scale top, disk 10 tops connect a truncated cone-shaped tube 11, on scale 5 shells back up pad 8 is arranged, place toroidal container 9 above the back up pad 8, above scale 5 bases 1 level meter 3 and 4 are arranged, regulate the screw 2 of base level, the middle part of scale 5 shells statistics have shown device 7 and counter 6, and there is handwheel 12 tube 11 upper ends.There is sliding pin 13 truncated cone-shaped tube 11 lower ends, the translot 15 that disk 10 has vertical slot 14 and communicates with vertical slot 14, and sliding pin 13 can insert vertical slot 14, the handwheel 12 of rotary cylinder 11 upper ends, sliding pin 13 enters translot 15, and tube 11 can be connected with disk 10.
Testing process: regulate the instrument base level, toroidal container 9 is placed on the back up pad 8 of scale 5, truncated cone-shaped tube 11 is connected with disk 10, tested fresh concrete is filled truncated cone-shaped tube 11, the upper surface is floating, be placed on the electronic scales and weigh, concrete weight number input counter 6, the handwheel of rotary cylinder upper end, make sliding pin skid off translot 15, portable handwheel 12 upwards pulls up truncated cone-shaped tube 11, tube 11 is separated with disk 10, concrete is scattered on the rosette 10, and the part concrete flows out disk 10 and falls in the toroidal container 9, claims concrete weight on the disk, calculate the concrete weight of inflow toroidal container and the ratio of original concrete general assembly (TW), this ratio can be accurate, objectively detect the slump of fresh concrete.The present invention can be widely used in and detect concrete workability in concrete test and the work progress.
