Concrete slump testing device for building construction

Abstract

The invention is applicable to the technical field of building construction testing devices, and particularly relates to a concrete slump testing device for building construction. The device comprisesa measuring cylinder, and further comprises a lifting assembly, a base and leveling supporting legs. The upper end of the lifting assembly is connected with the measuring cylinder; the lower end of the lifting assembly is embedded into the base and used for driving the measuring cylinder to ascend and descend; the lifting assembly is provided with a height measuring assembly, the height measuringassembly is used for measuring the slump of a concrete sample, the leveling supporting legs are arranged at the bottom of the base and used for quickly leveling the base, and an ultrasonic vibrationplate is arranged at the position, under the measuring cylinder, of an inner cavity of the base. According to the concrete slump testing device for building construction provided by the embodiment ofthe invention, automatic stirring of a concrete sample can be realized, so that air in the concrete sample is exhausted, automatic measurement and recording can be further carried out, and the accuracy of a testing result and the testing efficiency are greatly improved.

Description

technical field [0001] The invention belongs to the technical field of building construction testing devices, in particular to a concrete slump testing device for building construction. Background technique [0002] The slump is the method and indicator for the determination of the workability of concrete. In the construction site and laboratory, the fluidity of the mixture is usually measured by the slump test, and the cohesion and water retention are evaluated by visual experience. The slump is a quantitative index to measure its level, which is used to judge whether the construction can proceed normally. [0003] Test method of slump: use a trumpet-shaped slump barrel with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm, pour concrete into it and fill it three times. Hit 25 times, after tamping, smooth. Then pull up the barrel, the concrete will slump due to its own weight, and subtract the height of the highest point of the concrete after the bar...
