Problems solved by technology
[0003] In the current detection of concrete slump and expansion, when the detection cylinder needs to be lifted up from the concrete, it is manually lifted, which will easily cause the formed concrete to tilt, affecting the detection accuracy of slump and expansion. Secondly, after the detection is completed, the detection cylinder needs to be cleaned in time to prevent the concrete from solidifying, and the overall cleaning quality is low

The invention discloses a detection device capable of measuring slump and expansion degree of concrete in a wide range. The detection device comprises a shell mechanism, a body mechanism and a lifting mechanism, the body mechanism is arranged in the shell mechanism, the lifting mechanism is arranged on the upper surface of the shell mechanism. After concrete is tamped and flattened, current is introduced into an electromagnetic plate to enable the electromagnetic plate to have magnetism, meanwhile, a butt joint block is connected with a side plate, and an electromagnetic plate can slowly move upwards under the attraction of a positioning disc, so that a sleeve plate can drive the detection cylinder to move upwards, and the purpose of lifting the detection cylinder is achieved, on one hand, manual lifting is replaced, labor force is saved, and on the other hand, in the upward moving process of the detection cylinder, a phenomenon of shaking is avoided, the influence on the appearance of the formed concrete is prevented, and the accuracy of detecting the slump and the expansion degree is improved.
Description
technical field [0001] The invention relates to the technical field of concrete detection equipment, in particular to a detection device capable of measuring the slump and expansion of concrete in a large range. 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. cement temperature etc. Slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including the water retention, fluidity and cohesion of concrete, and workability refers to whether the concrete is easy to operate and uniformly dense , is a very comprehensive performance which includes fluidity, cohesion and water retention. The workability is mainly affected by water consumption, water-cement ratio, sand rate, cement type, aggregate condition, time and temperatur...
