Concrete slump detection device

Abstract

The invention discloses a concrete slump detection device which comprises a main body mechanism, an adjusting mechanism, an observing mechanism and a supporting mechanism, the adjusting mechanism is arranged on the outer surface of the main body mechanism, the observing mechanism is arranged on the outer surface of the adjusting mechanism, the supporting mechanism is arranged at the lower end of the adjusting mechanism, a communicating pipe and water storage barrels can form a communicating vessel, the communicating vessel principle is utilized, under the same atmospheric pressure, the liquidlevel heights of the two horizontal water storage barrels should be the same, when a conical barrel is placed, whether the conical barrel is in the horizontal state or not can be observed through thewater storage barrels, a fine adjustment mechanism is arranged at the upper end of the main box body, a fine adjustment block is fixedly installed at one end of a supporting column, a top seat is arranged at the other end of the supporting column, a threaded rod is arranged on one side of the supporting column, the supporting column is movably connected with a top seat through the threaded rod, the supporting column is connected with the adjusting sleeve plate through the top seat, and if not, adjustment is conducted through rotation of the top seat, so that the conical barrel is in a horizontal state, and slump detection errors are reduced.

Description

technical field [0001] The invention relates to the technical field of concrete detection equipment, in particular to a concrete slump detection device. Background technique [0002] Concrete slump mainly refers to the plasticizing performance and pumpability of concrete. Factors affecting concrete slump mainly include gradation change, water content, weighing deviation of scales, and the amount of admixture. The temperature of cement, etc., slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including water retention, fluidity and cohesion of concrete, workability refers to whether the concrete is easy to operate It is a very comprehensive performance that includes fluidity, cohesiveness and water retention. The main influences on workability are water consumption, water-cement ratio, sand rate, and cement types, aggregate conditions, time and temperature. , admixtures and other aspects, the slump of concrete should be d...

Problems solved by technology

[0003] The current concrete slump detection devices are all directly detected on the ground, so the error caused by the terrain on the detection results is not considered, so the measured slump is not accurate enough, and there are certain errors. When concrete is compacted, it is manually compacted. On the one hand, unnecessary labor is wasted, and on the other hand, working time is wasted. Too long compaction time will also lead to inaccurate final slump detection results.
