Description

Technical Field

[0001] This utility model relates to the field of concrete testing technology, specifically a novel concrete slump testing device. Background Technology

[0002] Currently, concrete slump testing requires the coordinated operation of various independent components, including a testing cylinder, funnel, vibrator, ruler, and measuring tape. The process is complex due to the dispersed nature of these components, and their storage is inconvenient, leading to potential loss. Furthermore, while shovels are commonly used for concrete pouring, their large flow surface often results in concrete loss. Measurement requires determining the slump height using a ruler before measuring with a steel measuring tape. This process involves numerous scattered and difficult-to-manage tools and parts, and the ruler needs manual adjustment, further complicating the operation. In some cases, the ruler is even discarded or lost during slump testing, leading to the use of a measuring tape for visual estimation or the random use of scrap materials like steel rebar scraps on-site. This violates regulations and compromises measurement accuracy. Utility Model Content

[0003] The purpose of this invention is to solve the problems existing in the prior art and provide a new type of concrete slump testing device that integrates the testing cylinder, scale, and measuring ruler to improve the overall integrity of the testing device, effectively solve the problem of relatively dispersed components, simplify the testing process, reduce the process of adjusting the height of the scale and cylinder, and allow for direct measurement, thereby improving measurement efficiency.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A novel concrete slump testing device includes a testing cylinder and a funnel disposed on the top of the testing cylinder. A scale baffle is horizontally disposed on the top of the outer wall of the testing cylinder. A connecting rod is disposed on the lower side of the scale baffle. One end of the connecting rod is hinged to the testing cylinder, and the other end is provided with an adjuster. When the connecting rod abuts against the bottom surface of the scale baffle, the connecting rod is in a horizontal state. The adjuster is mounted on the measuring scale, and the position of the adjuster on the measuring scale is adjustable.

[0006] Preferably, the funnel is a circular funnel or an elliptical funnel, wherein the bottom of the elliptical funnel is circular and the top is elliptical.

[0007] Preferably, the outer wall of the detection cylinder is provided with a handle.

[0008] Preferably, the adjuster has a through hole adapted to the measuring scale, and the outer wall of the adjuster has a locking screw for locking the relative position between the measuring scale and the adjuster.

[0009] Preferably, both the upper and lower ends of the measuring scale are provided with limiting elements to prevent the measuring scale from falling off the adjuster.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention integrates the original testing cylinder, scale, and measuring ruler, improving the overall integrity of the testing device and effectively solving the problem of relatively scattered components. It also simplifies the testing process, reducing the need for height calibration of the scale and cylinder opening, allowing for direct measurement and improving efficiency. Furthermore, considering practical construction site operations, the use of an elliptical funnel facilitates the pouring of concrete into the cylinder with a shovel, achieving a simple, practical, and highly efficient integrated concrete slump testing device.

[0018] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0019] Example: As attached Figure 1-5As shown, this utility model describes a novel concrete slump testing device, including a testing cylinder 1 and a funnel 2 located on top of the testing cylinder 1. The funnel 2 and the testing cylinder 1 can be an integral structure or a separate structure. A scale baffle 3 is horizontally welded to the top of the outer wall of the testing cylinder 1. A connecting rod 4 is provided on the lower side of the scale baffle 3. One end of the connecting rod 4 is hinged to the testing cylinder 1 through a hinge, and the other end is provided with an adjuster 5. When the connecting rod 4 abuts against the bottom surface of the scale baffle 3, the connecting rod 4 is in a horizontal state. The adjuster 5 is installed on a measuring scale 6, and the position of the adjuster 5 on the measuring scale 6 is adjustable. When the connecting rod 4 is in a horizontal state, the measuring scale 6 is in a vertical state. The measuring scale 6 is columnar and can be a steel ruler.

[0020] Preferably, the funnel 2 is a circular funnel or an elliptical funnel, wherein the bottom of the elliptical funnel is circular and the top is elliptical.

[0021] Preferably, in order to facilitate lifting the detection cylinder, handles 7 are symmetrically welded on the outer wall of the detection cylinder 1.

[0022] Preferably, in order to facilitate locking the relative position between the adjuster and the measuring scale, the adjuster 5 is provided with a through hole adapted to the measuring scale 6, and the outer wall of the adjuster 5 is provided with a locking screw 8 for locking the relative position between the measuring scale 6 and the adjuster 5 and a screw hole adapted to the locking screw 8, the screw hole communicating with the through hole.

[0023] Preferably, both the upper and lower ends of the measuring scale 6 are provided with limiting members 9 to prevent the measuring scale 6 from falling off the adjuster 5. The limiting members 9 can be rivets riveted to the measuring scale 6.

[0024] The detection cylinder 1 can be made of stainless steel, which is rust-resistant and has a strong overall structure. The circular funnel has an opening radius of 150mm and a closing radius slightly smaller than the opening of the detection cylinder 1, making it easy to connect with the opening of the detection cylinder 1. The elliptical funnel has a long side radius of 180mm and a closing radius the same as the circular funnel, making it easy to connect with the opening of the detection cylinder 1. The bottom of the detection cylinder 1 has a radius of 100mm, the top radius is 50mm, and the height is 300mm, which is the same as the common dimensions of detection cylinders. The scale baffle 3 is connected to the opening of the detection cylinder 1, with a length of 50mm and a width of 20mm. The connecting rod 4 is 130mm long and 5mm in diameter. The adjuster 5 is used to fix the measuring scale, and the side is equipped with a locking screw 8 for adjusting the measuring scale 6. The back of the adjuster 5 has a limiting post (the adjuster 5 is hinged to the connecting rod 4, and when the limiting post abuts against the connecting rod 4, the connecting rod 4 is perpendicular to the measuring scale 6). This component is also made of stainless steel and its main function is to limit the measuring scale and ensure that the measuring scale 6 is perpendicular to the horizontal plane. The measuring scale 6 is 290mm long and made of stainless steel, which can meet the actual concrete slump detection length requirements. Both ends of the measuring scale are equipped with limiting parts 9 to prevent the measuring scale 6 from falling off.

[0025] In use, the testing cylinder 1 is placed on a flat surface. A suitable funnel 2 is selected based on the construction conditions. Then, the concrete to be tested is poured into the testing cylinder 1, filling it one-third of its height each time. After each filling, the mixture is thoroughly vibrated until the top of the testing cylinder 1 is level. The funnel 2 is removed, and the testing cylinder 1 is pulled out vertically upwards within 5-10 seconds. After the concrete has collapsed, the testing cylinder 1 is placed at the edge of the concrete. The measuring scale 6 and connecting rod 4 are lifted, ensuring the connecting rod 4 contacts the scale baffle 3. The measuring scale 6 is then adjusted so that the smaller scale is at the bottom and the larger scale at the top, perpendicular to the horizontal plane. When the test... When ruler 6 is adjusted to be perpendicular to the horizontal plane, the limiting post contacts the connecting rod 4, preventing ruler 6 from increasing its angle and ensuring that ruler 6 is in a vertical state. At this time, by rotating the locking screw 8 on the adjuster 5 to control the tightness of ruler 6, the vertical height of ruler 6 can be adjusted. The measurement value is based on the upper edge of the adjuster 5. During the production process, by controlling the thickness of the scale baffle 3 and the size of the adjuster 5, it is ensured that when the connecting rod 4 and the scale baffle 3 are horizontal and ruler 6 is perpendicular to the horizontal plane, the upper edge of the adjuster 5, the mouth of the detection cylinder, and the upper surface of the scale baffle 3 are on the same horizontal line, thereby controlling the measurement value.
