Problems solved by technology

[0007] The operation is not standardized enough and is completely controlled by personnel. For example, the density of tamping varies according to the strength of the operator. During the process of unloading the bucket, the concrete will stick to the wall of the bucket, forming a negative pressure adsorption force, which makes the test The sample is elongated in the height direction, causing secondary damage to the sample and affecting the test effect
[0008] Whether the test platform is level has an important impact on the test results. The existing test process is basically tested on the ground, and the level of the platform cannot be guaranteed.
[0009] Combining the above factors, the existing testing tools need to be improved

Embodiment Construction

[0044] In response to the existing defects, a concrete slump test vehicle was developed, which was changed from a single test bucket to a test vehicle. The main purpose is to improve the accuracy and standardization of the test and avoid the adverse effects of human operation.

[0045] The basic principle is to change manual tamping to mechanical tamping. The intensity and time of tamping can be set to form standardization, increase the level adjustment function of the platform, form a horizontal state, and further improve the overall operability and Ease of operation.

[0046] Based on the above description, combined with Figure 2 to Figure 10 As shown, its structure is described in detail below:

[0047] Test cylinder 1 is installed, and this test cylinder 1 is conical as a whole, as Figure 4 , the bottom of the test cylinder is provided with an outer flange 11 for contacting with the platform to increase the contact area. And side ear 12 is set on the outer upper part ...

Abstract

The invention discloses a concrete slump testing vehicle. The concrete slump testing vehicle comprises a testing barrel, a trolley, a tamping mechanism, a measuring mechanism and a cleaning mechanism, wherein a flat plate with adjustable height and angle is arranged on a table board of the trolley, has three-dimensional adjusting capacity, and can be leveled conveniently; a first portal frame and a second portal frame are arranged on linear slide rails on the table board, the tamping mechanism is arranged on the first portal frame, the measuring mechanism is arranged on the second portal frame, the cleaning mechanism is arranged on the flat plate and matched with a blanking port in the table board for use, and a concrete recycling tank is fixed below the blanking port. The concrete slump testing vehicle is suitable for the in-situ concrete slump test, the levelness of a testing platform can be adjusted according to fields, the precision of a measurement result is guaranteed, tamping, demoulding strength and a process are more normative, and support is provided for accurate measurement of concrete slump.

Description

technical field [0001] The invention relates to the technical field of concrete slump test tools, in particular to a portable concrete slump test vehicle that can realize standardized measurement. Background technique [0002] Concrete slump mainly reflects the plasticizing performance and pumpability of concrete. The main factors affecting concrete slump include raw materials, mixing time, transportation machinery, pouring speed, pouring time, etc. In addition, the amount of additives and easily overlooked cement Temperature also affects metrics. [0003] Concrete slump refers to the workability of concrete, specifically to ensure the normal progress of construction, including water retention, fluidity and cohesion of concrete. [0004] Existing conventional test method for slump: Use a trumpet-shaped slump bucket with an upper mouth of 100mm, a lower mouth of 200mm, and a height of 300mm, pour concrete into it and compact it, then pull out the bucket, and the concrete wil...
