Description

Technical Field

[0001] This utility model relates to the technical field of concrete slump test equipment, and in particular to a slump cylinder. Background Technology

[0002] In the field of construction, concrete is one of the most widely used building materials. Its workability has a crucial impact on the quality of construction projects, construction progress, and cost control. Slump, as a key indicator for measuring the workability of concrete, can directly reflect the characteristics of concrete such as fluidity, plasticity, and compaction. Slump cones, as professional tools for accurately measuring the slump of concrete, are widely used in construction sites and various building material laboratories.

[0003] During the slump test, the operator needs to lift the slump cone vertically within 5-8 seconds. However, due to the influence of human perception, it is impossible to maintain a vertical position during the lifting process, resulting in angular deviation. Slight angular deviation can affect the accuracy of the test, and serious deviation can directly lead to the destruction of concrete, resulting in unqualified tests and affecting the project progress. Furthermore, after the slump cone is lifted, the concrete height needs to be measured. The current method is to first adjust the scale to the horizontal height of the slump cone, and then calculate the distance using a tape measure or ruler. This method is cumbersome, requires the use of multiple measuring tools simultaneously, increases labor costs, and takes too long, causing the concrete to continue to slump, resulting in inaccurate data. Therefore, the above problems need to be solved. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slump cone.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a slump cylinder, comprising a base and a slump cylinder mounted on the base, wherein a positioning groove is provided at the top of the slump cylinder, a feeding tray is installed in the positioning groove, and limit rods are installed on both sides of the slump cylinder, and a measuring rod is installed on the top surface of the base, the measuring rod being located at the rear end of the slump cylinder.

[0006] Preferably, ear plates are fixed to both sides of the bottom of the slump cylinder, and the two ear plates are respectively sleeved on two limiting rods, and lifting rings are hinged to the front and rear ends of the upper part of the slump cylinder.

[0007] Preferably, the bottom end of the slump cone abuts against the base.

[0008] Preferably, the feeding tray is an inverted cone shape, and three positioning posts are fixedly connected at equal intervals at the bottom of the feeding tray, with the three positioning posts respectively inserted into the corresponding positioning slots.

[0009] Preferably, the measuring rod is engraved with a scale, and a measuring ruler is rotatably connected to the top of the measuring rod, the height of which is flush with the top of the slump cylinder.

[0010] Preferably, the measuring ruler can slide on the measuring rod, and a damper is installed at the connection between the measuring rod and the measuring ruler.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The cooperation between the ear plate and the limiting post ensures that the slump cylinder remains vertical when the operator lifts it upwards, thus avoiding data errors caused by angular deviations and improving test accuracy. Furthermore, the use of the measuring plate allows for the scraping off of excess concrete from the top of the slump cylinder. During measurement, the cylinder only needs to be rotated above the concrete before being lowered to measure the slump, reducing cumbersome reading procedures and allowing for operation by a single operator, thereby lowering costs and improving data accuracy. Ultimately, this solves the problems of data deviation caused by the inability to maintain verticality when lifting the slump cylinder and data errors due to cumbersome reading procedures.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a slump cone, comprising a base 1 and a slump cone 2 mounted on the base 1. The base 1 facilitates the placement of the slump cone 2. A positioning groove is provided at the top of the slump cone 2, which facilitates the installation of a material feeding tray 3. The material feeding tray 3 is installed in the positioning groove to prevent concrete from falling outside during pouring. Limiting rods 4 are installed on both sides of the slump cone 2 to prevent the slump cone 2 from tilting when lifted. A measuring rod 5 is installed on the top surface of the base 1, which facilitates reading with a measuring ruler 9. The measuring rod 5 is located at the rear end of the slump cone 2. Ear plates 6 are fixed to both sides of the bottom of the slump cone 2, which facilitate vertical lifting and lowering with the limiting rods 4. The two ear plates 6 are respectively sleeved on the two limiting rods 4, and lifting rings 7 are hinged to the front and rear ends of the upper part of the slump cone 2, which facilitates lifting the slump cone 2.

[0020] In this invention, the bottom end of the slump cylinder 2 abuts against the base 1, the feeding tray 3 is an inverted cone shape, and three positioning posts 8 are fixedly connected at equal intervals at the bottom end of the feeding tray 3. The positioning posts 8 facilitate the installation of the feeding tray 3. The three positioning posts 8 are respectively inserted into the corresponding positioning slots. The measuring rod 5 is engraved with a scale, and the top end of the measuring rod 5 is rotatably connected to a measuring ruler 9. The measuring ruler 9 can scrape off excess concrete at the top of the slump cylinder 2 and can also quickly read the value. The height of the measuring ruler 9 is flush with the top end of the slump cylinder 2. The measuring ruler 9 can slide on the measuring rod 5, and a damper is installed at the connection between the measuring rod 5 and the measuring ruler 9 to prevent the measuring ruler 9 from sliding down.

[0021] Working principle: When using this utility model, first place the slump cylinder 2, limiting rod 4, and measuring rod 5 on the base 1. Then, insert the slump cylinder 2 into the limiting rod 4 through the ear plate 6. Next, align the positioning column 8 with the positioning groove and install the material tray 3 on the slump cylinder 2. At this point, the device is installed. Then, pour concrete into the slump cylinder 2 and mix the concrete according to the testing standards. After the slump cylinder 2 is full of concrete, remove the material tray 3. Rotate the measuring ruler 9 to scrape the concrete until it is level with the slump cylinder 2. Rotate the measuring ruler 9 back to its original position and pull the lifting ring 7. With the cooperation of the limiting rod 4 and ear plate 6, the slump cylinder 2 is lifted vertically. Then, rotate the measuring ruler 9 to directly above the concrete and push the measuring ruler 9 down to be level with the top of the concrete to take the reading. Finally, subtract the concrete height from the initial slump cylinder 2 height data to obtain the test data.
