Concrete slump testing device for building construction

Abstract

The invention relates to the field of building construction devices, in particular to a concrete slump testing device for building construction. The concrete slump testing device includes: a mountingbase; a rack which is arranged above the mounting base; a horizontal adjusting mechanism which is arranged between the mounting base and the rack; a shaping device which is arranged on the rack, wherein the shaping device is fixedly connected with the rack, the input end of the shaping device is arranged at the upper end of the rack, and the working end of the shaping device is arranged in the rack; a vibration supporting plate which is horizontally arranged on the rack, wherein the vibration supporting plate is fixedly connected with the rack, and the working end of the vibration supporting plate is attached to the bottom of the shaping device; a measuring device, wherein the measuring device is arranged at the side part of the rack, and the measuring device is fixedly connected with therack; and a concrete pushing device which is arranged on the rack, wherein the concrete pushing device is fixedly connected with the rack, the working end of the concrete pushing device is arranged below the vibration supporting plate. Concrete slump data can be rapidly and accurately tested.

Description

technical field [0001] The invention relates to the field of building construction devices, in particular to a concrete slump testing device for building construction. Background technique [0002] Concrete slump is the measurement method and index of concrete workability. In construction sites and laboratories, slump tests are usually used to measure the fluidity of mixtures, and visual experience is used to evaluate cohesion and water retention. The slump is a quantitative index to measure its level, which is used to judge whether the construction can proceed normally. 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 barrel height (300mm) from the barrel, which is c...

Problems solved by technology

During the construction process, people usually use a fully artificial form to test the slump. During the test, they are stirred by a stick to discharge the air in it. The efficiency of the slump test is low and the air is discharged. The effect is poor, leading to inaccurate test results. If the construction personnel tilted when pulling up the bucket, the slump test results will also be affected. Therefore, a concrete slump test device for building construction is needed to solve the above problems.
