Abstract
Description
Technical Field
[0001] This utility model relates to the field of concrete slump testing technology. More specifically, this utility model relates to a concrete slump testing material loading tool. Background Technology
[0002] In concrete slump testing, concrete needs to be filled into the slump cone in three stages, with each layer filling to a height slightly above one-third of the cone's height. Traditionally, square or pointed shovels are used to scoop the concrete into the slump cone. However, this method is limited by the tools used, resulting in inconsistent filling heights and concrete slurry overflowing during the process. This overflow can splatter onto the testing personnel's shoes and trousers, potentially leading to inaccuracies in the slump test data. To ensure accurate data, a uniform filling height and a consistent concrete slurry-to-aggregate ratio are necessary. Utility Model Content

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.
[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will occur to those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.
[0023] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0024] like Figure 1-2 As shown, a preferred embodiment of this utility model provides a concrete slump testing loading tool, including a loading assembly, an anti-overflow assembly, and a handle 8;
[0025] The loading assembly includes a base plate 1 and a left side baffle 2, a right side baffle 3 and a rear side baffle 4, which are integrally formed with the base plate 1. The left side baffle 2 and the right side baffle 3 are parallel to each other, and the rear side baffle 4 is perpendicularly connected to the left side baffle 2 and the right side baffle 3, forming a U-shaped cavity. The outer side of the rear side baffle 4 is fixedly connected to one end of the handle 8. The length L of the base plate 1 satisfies L≤D, where D is the diameter of the loading port above the slump test cylinder.
[0026] The anti-overflow component includes an inclined plate 5 and a left inclined baffle 6 and a right inclined baffle 7 vertically arranged on both sides of the inclined plate 5. The length of the inclined plate 5 matches the length of the bottom plate 1. The anti-overflow component is fixedly connected to the open end of the loading component to form an integrated shovel structure. The volume design of the shovel structure satisfies that 3 shovels, 2 shovels, and 1 shovel correspond to the standard filling amounts of the first, second, and third layers of the slump test cylinder, respectively.
[0027] In this embodiment, a preferred implementation is that the left side baffle 2, the right side baffle 3 and the rear side baffle 4 are all 40mm high, the bottom plate is 170mm long and 130mm wide, and the inclined plate 5 is 32mm wide. This shovel structure allows its loading volume to meet the requirement of being slightly higher than the height of 1 / 3 of the slump test cylinder.
[0028] Furthermore, in the concrete slump testing loading tool, the angle between the inclined plate 5 and the base plate 1 is 150°, which slows down the concrete flow rate and reduces spillage.

The detachable extension strips 9 are made of magnetically conductive material and have a magnetically conductive contact surface at the bottom, and are connected to the permanent magnets 15 by magnetic attraction.
[0031] In this embodiment, a preferred technical solution is that the detachable extension strip 9 is made of Q235 low carbon steel, which has good magnetic conductivity and low cost. The surface is galvanized or coated with anti-rust paint, which has high durability. The permanent magnet 15 is made of neodymium iron boron, which is small in size but has strong attraction. The surface is plated with nickel or epoxy resin coating to prevent corrosion.
[0032] Furthermore, the concrete slump testing loading tool has a fluorescent scale line 10 on the inner side of the detachable extension strip 9, which can be used to select the height corresponding to 1 / 3 of the filling volume of different slump testing cylinders. It is also set to be fluorescent for easy use at night or in dim light.
[0033] Furthermore, in the concrete slump testing loading tool, the top of the left side baffle 2, the right side baffle 3, and the rear side baffle 4 are all provided with several positioning grooves 17, and the bottom of the detachable extension strip 9 is provided with several positioning protrusions 16 that cooperate with the positioning grooves 17 to prevent lateral sliding.
[0034] Furthermore, the inner walls of the left side baffle 2, right side baffle 3, rear side baffle 4, bottom plate 1, inclined plate 5, left side inclined baffle 6, and right side inclined baffle 7 of the concrete slump testing loading tool are all coated with a Teflon anti-stick coating to reduce concrete residue and improve loading accuracy and cleaning efficiency.
[0035] Furthermore, the concrete slump testing loading tool has a hanging hole 13 at the end of the handle 8 for hanging on a wall, hook, or other fixed device, which facilitates storage and organization and saves space.
[0036] Furthermore, in the concrete slump testing and loading tool, the inner surface of the inclined plate 5 is provided with several guide grooves 12 to guide the concrete from the surface of the inclined plate into the slump cylinder in a concentrated manner, thereby reducing spillage.
[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
