Description

Technical Field

[0001] The utility model belongs to the technical field of construction engineering detection, and in particular relates to a slump detection device. Background Art

[0002] Before concrete pouring construction, it is necessary to test the water retention, fluidity and cohesion of the concrete to determine whether the concrete can be used for normal construction. The existing technology uses three times of filling concrete into the slump bucket. After each filling, the tamping rod is used to tamp 25 times. When tamping the second and top layers, the tamping rod penetrates the current layer and extends downward by 20 to 30 mm. Then the bucket is pulled up and the height of the concrete collapse due to its own weight is measured to measure the slump of the concrete.

[0003] A Chinese patent with publication number CN219245293U discloses a concrete sample detection device for construction engineering, including a base, a support frame, a crossbeam, a reduction motor, a connecting rod transmission structure and a tamping rod. The above scheme utilizes the connecting rod structure so that the reduction motor can drive the tamping rod to reciprocate up and down to tamp the concrete, making the detection data more accurate.

[0004] However, the main problems with the concrete sample testing device for construction projects are: when inserting and tamping the second and top layers, the tamping rod still extends into the bottom of the first layer of concrete, which does not meet the experimental operation requirements; when lifting the slump bucket, the tamping rod is still inserted in the concrete, sticking to the concrete, affecting the accuracy of the experimental data. Utility Model Content

[0005] The utility model aims to provide a slump detection device to meet the experimental operation requirements and solve the problem that a tamping rod is inserted into concrete and adheres to the concrete, thus affecting the accuracy of experimental data.

After the insertion and tamping is completed, rotate the tamping rod so that the lower edge of the tamping rod is separated from the concrete, and finally smooth the concrete along the mouth of the slump bucket, lift the slump bucket vertically upward, adjust the cross bar of the measuring rod up and down, so that the lower edge of the cross bar just contacts the highest point of the concrete after collapse, read the height of the highest point of the concrete after collapse, and calculate the slump.

[0015] Through the above arrangement, on the one hand, when the tamping rod is inserted into the second and top layers of concrete, the tamping rod is limited to penetrate the current layer and only extends downward 20 to 30 mm to meet the experimental operation requirements; on the other hand, after the insertion is completed, the tamping rod is separated from the concrete to avoid the tamping rod from producing adhesion to the concrete and affecting the accuracy of the experimental data.
