Description

Technical Field

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

[0002] Slump mainly refers to the plasticization and pumpability of concrete. It is a quantitative indicator to measure its degree and is used to determine whether the construction can proceed normally.

[0003] The traditional slump measuring device has the following problems in actual use:

[0004] First, because the cylinder is opaque and has a structure that is small at the top and large at the bottom, there is no good sight during operation, and there is no real-time monitoring of the cylinder status, which increases the difficulty of three-layer loading;

[0005] Secondly, due to the different operators, the location and force of tamping are very different. The difference in tamping will seriously affect the organizational form of concrete in the cylinder. Less tamping will cause the central aggregate to accumulate, making the result smaller. More tamping may cause the concrete to collapse, and the result will be larger. Irregular tamping will often lead to larger errors in the slump results.

[0006] Finally, the traditional slump cone only has two sections of iron plates extending from the bottom, and the operator needs to step on the pedal to ensure the stability of the cylinder. Because the iron plate of the pedal is small, during the layer loading and tamping process, the stability of the cylinder is often destroyed under the action of external force because the pedal is not stepped on firmly. Before the operation process is completed, the concrete will flow out from the unstable place at the bottom, affecting the final result and increasing the workload of civilized construction. In addition, because the iron plate is prone to plastic deformation, it is more difficult to maintain stability, and the service life of the slump cone is also shortened. Utility Model Content

[0007] The utility model aims to solve the problems of poor stability and low measurement accuracy of slump measuring devices in the prior art, and proposes a concrete slump measuring device.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A concrete slump measuring device comprises a working plate and a cylinder, wherein the cylinder is located on the upper surface of the working plate, a feed hopper is matched with the cylinder, a rubber gasket is fixedly connected to the bottom end of the cylinder, and a transparent strip is fixedly arranged on the side wall of the cylinder;

[0010] The cylinder body and the working plate are provided with fixing mechanisms which are used in cooperation with each other and are used to fix and limit the cylinder body and the working plate.

[0011] Preferably, the working plate is a rectangular plate, and the cylinder is a hollow frustum structure with openings at both ends.

[0012] Preferably, the upper end of the feed hopper is an inverted bucket-shaped structure, and the lower end of the feed hopper is a circular tube-shaped structure.

[0013] Preferably, the rubber gasket is a circular ring structure, and the transparent strip is a rectangular structure.

[0014] Preferably, the fixing mechanism includes a first mounting frame bolted to the working plate, a second mounting frame bolted to the cylinder, an elastic plastic frame fixedly connected to the first mounting frame, two limit members rotatably mounted on the elastic plastic frame, and a wedge block movably abutting against one side of the limit member is bolted to the second mounting frame.

[0015] Preferably, the limiting member is a disc-shaped structure, and the wedge-shaped block is an arrow-shaped structure.

[0016] Compared with the prior art, the utility model has the following advantages:

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 4 A concrete slump measuring device comprises a working plate 1 and a cylinder 2. The cylinder 2 is located on the upper surface of the working plate 1. The working plate 1 is a rectangular plate. The cylinder 2 is a hollow truncated cone structure with openings at both ends. The upper end of the cylinder 2 is opened to provide a working space for the staff.

[0026] The cylinder 2 is equipped with a feed hopper 3, the upper end of the feed hopper 3 is an inverted bucket structure, and the lower end of the feed hopper 3 is a circular tube structure. The inverted bucket structure at the upper end of the feed hopper 3 can prevent concrete from splashing out;

[0027] The bottom end of the cylinder 2 is fixedly connected with a rubber gasket 4, which is a circular ring structure. The setting of the rubber gasket 4 helps to improve the air tightness and stability of the bottom of the cylinder 2, thereby ensuring that the concrete will not flow out from the bottom during the measurement process;

[0028] A transparent strip 5 is fixedly arranged on the side wall of the cylinder 2. The transparent strip 5 is a rectangular structure. Through the arrangement of the transparent strip 5, the staff can observe the internal operation of the cylinder 2, ensure that the organization morphology of the concrete in the cylinder meets the requirements, the central aggregate does not accumulate, and reduce the error;

[0029] The cylinder 2 and the working plate 1 are provided with a fixing mechanism for use in conjunction with each other and for fixing and limiting the cylinder 2 and the working plate 1. The fixing mechanism can ensure the connection stability between the cylinder 2 and the working plate 1;

[0030] It is further explained that: the fixing mechanism includes a first mounting frame 6 fixed by bolts on the working plate 1, a second mounting frame 7 is bolted on the cylinder 2, an elastic plastic frame 8 is fixedly connected to the first mounting frame 6, and the elastic effect of the elastic plastic frame 8 is utilized to enable the elastic plastic frame 8 to be reset after being subjected to force, and two limit members 9 are rotatably installed on the elastic plastic frame 8, and the limit member 9 is a disc-shaped structure, and the limit member 9 can be rotated by the rotation setting of the limit member 9, and a wedge block 10 that is movably opposed to one side of the limit member 9 is bolted on the second mounting frame 7, and the wedge block 10 is an arrow-shaped structure, which helps to reduce the friction generated when the limit member 9 moves on the wedge block 10.

[0031] The functional principle of the utility model can be explained through the following operation modes:

[0032] Install the rubber gasket 4 at the bottom end of the cylinder 2, place the cylinder 2 on the working plate 1, fix the first mounting bracket 6 on the cylinder 2 with bolts, and fix the second mounting bracket 7 on the working plate 1 with bolts, and squeeze the limiter 9 with the wedge block 10 to move outwards. Under the elastic action of the limiter 9, the limiter 9 makes the wedge block 10 movably resist, so as to ensure that the device no longer tilts forward and backward during operation;

[0033] The feed hopper 3 is placed in the upper end of the cylinder 2 , and the changes of the plastic concrete in the cylinder 2 are observed through the transparent strip 5 .
