A concrete slump detection device

Abstract

The invention discloses a concrete slump detection device, which comprises a main body mechanism, an adjustment mechanism, an observation mechanism and a support mechanism, an adjustment mechanism is arranged on the outer surface of the main body mechanism, an observation mechanism is arranged on the outer surface of the adjustment mechanism, and the adjustment mechanism The lower end of the tank is provided with a support mechanism, and the connecting pipe and the water storage tank can form a connecting device. Using the principle of the connecting device, under the same atmospheric pressure, the liquid level of the two horizontal water storage tanks should be the same. When placing the conical tube, you can first Check whether the conical cylinder is in a horizontal state through the water storage cylinder, and the upper end of the main box is provided with a fine-tuning mechanism, one end of the support column is fixed with a fine-adjustment block, the other end of the support column is provided with a top seat, and one side of the support column is provided with a The threaded rod, the supporting column is movably connected with the top seat through the threaded rod, and the supporting column is connected with the adjustment sleeve plate through the top seat. Slump detection error.

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.
