Description

Technical Field

[0001] This application relates to the field of slump testing technology, and more specifically, to a simple device for facilitating the determination of slump. Background Technology

[0002] Concrete slump mainly refers to the plasticizing and pumpability properties of concrete. Factors affecting concrete slump mainly include changes in gradation, water content, weighing deviation of weighing instruments, and dosage of admixtures. Cement temperature is also easily overlooked.

[0003] Slump refers to the workability of concrete, specifically ensuring proper construction. It includes the concrete's water retention, fluidity, and cohesiveness. Workability refers to the ease with which concrete can be worked and to its ability to achieve uniform density; it is a comprehensive property encompassing fluidity, cohesiveness, and water retention. Factors affecting workability include water usage, water-cement ratio, sand ratio, as well as cement type, aggregate conditions, time and temperature, and admixtures.

[0004] The slump of concrete should be determined based on factors such as the structural cross-section of the building, the amount of reinforcing steel, the transportation distance, the pouring method, the transportation mode, the vibration capacity, and the climate. These factors should be taken into account when selecting the mix proportion, and a smaller slump is preferable.

[0005] Existing slump testing devices cannot accurately detect the slump of concrete after it has been compacted. As the concrete itself weighs down, it will continue to move downwards and eventually collapse. If the slump of the concrete cannot be accurately detected, it will affect the normal use of the concrete. Furthermore, the unevenness of the ground will also affect the slump detection.

[0006] To address the aforementioned problems, this application provides a simple device for easily measuring slump. Utility Model Content

[0029] Example:

[0030] This application discloses a simple device for easily measuring slump. Please refer to [link to relevant documentation]. Figures 1-5 The system includes a base 1, with a slump cylinder body 2 snapped onto the upper end of the base 1. An expanded feed ring 3 is snapped onto the upper end of the slump cylinder body 2. A scale rod 4 and a locking rod 5 are provided on the upper end of the base 1. A level 12 is also provided on the upper end of the base 1. A first through groove 13 and a first locking groove 131 are formed through the upper end of the base 1, and the first through groove 13 and the first locking groove 131 are connected. Adjusting bolt support rods 11 are evenly arranged at the four corners of the lower end of the base 1. The slump cylinder body 2... A handle 21 is fixedly connected to the outer surface of the middle part of the slump cylinder body 2. A fixed base plate 22 is fixedly connected to the outer surface of the lower end of the slump cylinder body 2. A placement plate 41 is fixedly connected to the lower end of the scale rod 4. A collar 42 is slidably connected to the outer surface of the scale rod 4. A screw 43 is threaded through the outer side of the collar 42. A locking block 51 is fixedly connected to the outer surface of the lower end of the locking rod 5. A stop block 52 is fixedly connected to the upper end of the locking rod 5. A pull rod 521 is fixedly connected to the upper end of the stop block 52.

[0031] The upper end of the fixed base plate 22 is provided with a second through groove 221 and a second slot 222. The second through groove 221 and the second slot 222 are connected. The second through groove 221 is connected to the first through groove 13, and the second slot 222 is connected to the first slot 131.

[0032] The fixed base plate 22 is used to place the slump cylinder body 2 at the center of the upper end of the base 1. The presence of the second through groove 221 and the second slot 222 facilitates the free passage of the clamping rod 5 and the clamping block 51.

[0033] The slump cylinder body 2 is located at the center of the upper end of the base 1. The level 12 is located on the outside of the slump cylinder body 2. The locking rod 5 passes through the interior of the first through groove 13 and the second through groove 221. The locking block 51 passes through the interior of the first locking groove 131 and the second locking groove 222. The stop block 52 is located at the upper end of the fixed base plate 22. The locking block 51 is located at the lower end of the base 1.

[0034] The lever 5 can easily pass through the interior of the fixed base plate 22 and the base 1. The cooperation between the locking block 51 and the stop block 52 is used to limit the fixed base plate 22 and fix it to the upper end of the base 1.

[0035] A scale 421 is fixedly connected to the outer side of the collar 42. A placement groove 422 is opened on the inner wall of the collar 42. A through groove 4221 is opened through the inner side of the placement groove 422. The through groove 4221 passes through the outer wall of the collar 42. A screw head 432 is fixedly connected to one end of the screw 43. A friction block 431 is fixedly connected to the other end of the screw 43.

[0036] The collar 42 can slide up and down along the outer surface of the scale rod 4. The scale 421 and the scale rod 4 work together to display the height of the concrete inside the slump cylinder body 2.

[0037] The screw 43 is threaded through and connected inside the through groove 4221. The screw head 432 is located on the outside of the collar 42. The friction block 431 is located on the inside of the collar 42. The friction block 431 is slidably engaged with the placement groove 422. The outer end of the friction block 431 is attached to the outer surface of the scale rod 4.

[0038] The placement groove 422 is used to place the friction block 431, and the screw head 432 is used to drive the screw 43 to rotate in the through groove 4221 to push the friction block 431 closer to the scale rod 4.

[0039] The implementation principle of this embodiment is as follows: When it is necessary to measure the slump, firstly, place the base 1 on the ground, and adjust the height and level of the base 1 according to the adjusting bolt support 11. Then, adjust the upper end of the base 1 to a horizontal state according to the level 12. Next, place the assembly of the slump cylinder body 2 and the expanded feed ring 3 at the center of the upper end of the base 1, and align the second through groove 221 with the first through groove 13. Then, align the assembly of the locking rod 5 and the locking block 51 with the second through groove 221 and the second locking slot 222 until the locking block 51 passes through the interior of the second locking slot 222 and the first locking slot 131. Then, rotate the pull rod 521 to offset the locking block 51 from the first locking slot 131. At this time, the interaction between the locking block 51 and the stop block 52 will position the fixed base plate 22. The slump cylinder body 2 is fixed at the center of the upper end of the base 1. Then, concrete can be injected into the slump cylinder body 2 through the expanded feed ring 3. Next, the collar 42 is moved to align the scale 421 with the upper edge of the concrete in the slump cylinder body 2. At this time, the screw head 432 can be rotated to make the friction block 431 stick tightly to the outer surface of the scale rod 4. Under the action of the friction block 431, the collar 42 is fixed to the outer surface of the scale rod 4. As time goes by, the concrete will collapse under its own gravity and continuously move down inside the slump cylinder body 2. As the concrete moves down, the collar 42 can be pulled down along the outer surface of the scale rod 4 until the scale 421 is moved to the upper edge of the collapsed concrete. At this time, the slump of the concrete can be measured by the distance the collar 42 moves on the scale rod 4.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
