Description

Technical Field

[0001] The utility model relates to the technical field of concrete slump detection, in particular to a concrete slump measurement barrel and a concrete slump measurement device. Background Art

[0002] Concrete is artificially mixed stone, hence the name "concrete." It's a general term for engineering composite materials composed of aggregates bonded together by a cementitious material. Concrete generally refers to cement as the binder, sand and stone as aggregates, mixed with water and possibly admixtures and additives in a specific proportion, and then mixed. Cement concrete, also known as ordinary concrete, is widely used in civil engineering.

[0003] Concrete slump is a key indicator of concrete's performance and a key parameter for its flowability. It's often used to measure concrete's suitability and quality. Concrete with a high slump is highly fluid and easy to fill into formwork, making it easier to construct. Concrete with a low slump, on the other hand, has difficulty flowing.

[0004] The slump of concrete is, to a certain extent, related to its strength, durability, and other properties. Excessive slump can reduce its strength and durability, potentially leading to shrinkage and cracking, and potentially causing quality issues. Large-scale construction projects often require that the slump of concrete fall within a specified range to ensure quality and performance.

[0005] During the testing process, concrete samples collected as required are loaded into the drum in batches, and then compacted using a tamping rod. Because the thickness of each layer after compaction affects the reliability of the test data, the concrete samples need to be pre-assembled and then loaded into the drum in sequence. This loading method is quite cumbersome. Utility Model Content

The strip plate is made of transparent material to form an observation area.

[0010] A concrete slump measuring device proposed by the present utility model includes: a barrel for measuring the slump of concrete as described above, and a tamper for tamping. The tamper is provided with axially arranged scales and a position limiter that can be adjusted axially. Moreover, the size of the position limiter in the vertical direction of the tamper is larger than the diameter of the small end of the barrel.

[0015] Figure 2 is a schematic structural diagram of a concrete slump measuring device proposed by the present utility model. Detailed Embodiments

[0016] Refer to Figure 1 A barrel for measuring the slump of concrete proposed by the present utility model includes: a barrel 1 for loading concrete specimens. The barrel 1 is a tapered barrel that is vertically through, and a transparent observation area 2 is provided on the side wall of the barrel 1; the observation area is a strip-shaped structure arranged along the axis of the barrel 1, and scales are provided on the side of the observation area.

[0017] Specifically, the side wall of the barrel 1 is provided with a cut extending from one end port to the other end port and a strip plate arranged inside the cut to connect the side walls on both sides of the cut. The strip plate is made of a transparent material to form an observation area.

[0018] When it is necessary to detect the slump of concrete, the concrete samples obtained as required are poured into the barrel 1 in batches. When pouring the concrete samples into the barrel 1, the thickness of each layer of concrete can be accurately controlled through the observation area and the scale arranged in the observation area, thereby ensuring that the thickness of each layer of concrete meets the requirements, reducing the batching steps, and the layer thickness of each layer can be arbitrarily controlled as needed, which is very convenient.

[0019] In addition, in this embodiment, a first sealing ring 3 is provided at the large-mouth end of the barrel 1. When the barrel 1 is placed on a plane, the first sealing ring 3 can achieve a good sealing effect and prevent the concrete in the barrel from overflowing.

[0020] Refer to Figure 2 As shown in the figure, a concrete slump measuring device proposed by the present utility model includes: the concrete slump measuring barrel as described above, and a tamping rod 4 for tamping. The tamping rod 4 is provided with axially arranged scales and a position limiter 5 that can be axially adjusted. Moreover, the size of the position limiter 5 in the upward direction of the tamping rod 4 is larger than the diameter of the small-mouth end of the barrel 1, so that the position limiter 5 cannot enter the barrel 1, thereby realizing the limitation of the tamping depth of the tamping rod 4 during the material guiding process. Then, during the process of tamping the concrete poured into the barrel 1 with the tamping rod 4, when each layer is formed and the next layer of tamping operation is carried out, according to the layer thickness of the concrete layer and referring to the scale on the tamping rod 4, the position of the position limiter 5 on the tamping rod 4 is readjusted to ensure that the tamping rod 4 does not penetrate into other layers during tamping, so as to ensure the most real cohesiveness and density of the concrete mixture, and then ensure the accuracy of the slump detection. And the base can ensure the flatness of the bottom of the barrel 1.

[0021] Furthermore, the position limiter 5 includes a hoop 51 sleeved on the tamping rod 4, a limiting rod 52 radially fixed on the hoop 51, and a fastening bolt 53 for fastening the hoop 51 on the tamping rod 4. And the length of the limiting rod 52 is greater than the diameter of the small-mouth end of the barrel 1. When it is necessary to adjust the position of the position limiter 5, loosen the fastening bolt 53, adjust the position of the hoop 51 on the tamping rod 4 according to the scale of the tamping rod 4, and finally tighten the fastening bolt 53 again.

[0022] In addition, a concrete slump measuring device proposed by the present utility model further includes a rotating base 6, a column 7, a support base 8, as well as a first driving mechanism and a second driving mechanism, wherein: the upper surface of the support base 8 is a plane; the rotating base 6 is installed on the support base 8 and is connected to the first driving mechanism to be driven to rotate by the first driving mechanism; the column 7 is vertically fixed on the rotating base 6, and a vertically arranged linear guide rail is provided on the column 7, and a sliding seat 9 is provided on the linear guide rail; the second driving mechanism is connected to the sliding seat 9 to drive the sliding seat 9 to slide on the linear guide rail; the material cylinder 1 is vertically arranged above the support base 8, and its large mouth end faces downward; a connecting component 10 is provided on the side of the material cylinder 1, and the connecting component 10 is fixedly connected to the sliding seat 9, so that the material cylinder 1 can move along with the movement of the sliding seat 9, and then the material cylinder 1 can automatically move in the vertical direction.

[0023] When conducting the concrete slump test, first lower the material cylinder 1 until its lower end abuts against the support base 8, then pour the concrete specimen into the material cylinder 1 in batches and tamp it layer by layer with the tamping rod 4; finally, lift the material cylinder 1 until the material cylinder 1 is separated from the concrete pile. When it is necessary to clean the tabletop of the support base 8, drive the rotating base 6 to rotate to drive the material cylinder 1 to rotate to the outside of the support base 8 to avoid affecting the cleaning work of the support base 8.

[0024] This structural design can avoid damaging the shape of the concrete pile due to unstable force when manually removing the cylinder, thereby affecting the concrete slump test.

[0025] Furthermore, a second sealing ring 11 is provided on the support base 8, and the material cylinder 1 is located inside the second sealing ring 11. After the material cylinder 1 is removed from the concrete pile, the second sealing ring 11 can ensure that the concrete does not overflow in its inner area, which is convenient for hygienic cleaning, protects the environment, and saves water.

[0026] Furthermore, a positioning groove is provided on the support base 8, the positioning groove is an annular groove, and the second sealing ring 11 includes an assembly part located in the positioning groove and a convex part protruding above the upper surface of the support base 8. When it is necessary to replace the second sealing ring 11, only need to take out the second sealing ring 11 from the positioning groove and replace it with a new one.

[0027] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its utility model concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
