Description

Technical Field

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

[0002] Building construction involves assembling a frame from concrete and steel reinforcement, filling the frame with air-filled blocks, and then applying cement slurry. Before use, the concrete needs to undergo a slump test. The testing equipment typically consists of a cone, base plate, tamping rod, and measuring ruler. During the test, the cone is placed on the base plate, concrete is shoveled into the cone, and the concrete is tamped down using a tamping rod. Any excess concrete at the top of the cone is then scraped off with a trowel. During this process, some concrete will fall onto the base plate, requiring further effort to clean it off and level it using a tamping rod. This manual operation is also necessary, and the base plate cannot be adjusted for levelness, leading to inaccuracies in the concrete slump test results. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a building quality testing device, which has the following features:

[0015] Beneficial effects:

[0016] This building quality inspection equipment works by pouring concrete into a cone and manually controlling the rotation of a scraper to level the concrete at the top of the cone, and manually controlling the rotation of a scraper blade to collect and clean up the concrete that falls onto the chassis. Both methods quickly remove or clean up the concrete.

[0017] Four sets of vibration motors are set up, with three in each set, arranged at equal intervals from top to bottom. After each pour of concrete, one set of vibration motors is started. The vibration force can level the concrete inside the cone until the concrete fills the entire cone. No manual vibration is required during this process, which improves the testing efficiency.

[0018] Based on the bubble offset in the level, the threaded column under the chassis is rotated. The threaded column extends or retracts into the threaded cylinder, causing the pad to move up or down until the bubble in the level is centered. This adjusts the horizontal height difference of the chassis and reduces discrepancies in concrete test data. Attached Figure Description

[0026] In the description of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model.

[0027] Please see Figure 1-6 A building quality inspection device includes a chassis 1. Three electric push rods 2 are fixedly installed on the top of the chassis 1 in a ring. A crossbar 3 is fixedly installed at the output end of the electric push rod 2. A fixing ring 4 is fixedly installed at the other end of the crossbar 3. A cone 5 is fixedly installed inside the fixing ring 4. By extending the output end of the electric push rod 2, the cone 5 can move upward, and the concrete in the cone 5 will collapse. Compared with the traditional method of manually moving the cone 5, the upward movement of the cone 5 in this application will not have any displacement.

[0028] Please see Figure 1-6 Limit rings 6 are fixedly installed at the top and bottom of the cone 5. Vibration motors 7 are fixedly installed on the outside of the cone 5. There are four sets of vibration motors 7, with three in each set, arranged in a ring. An eccentric wheel is fixedly installed at the output end of the vibration motor 7. The vibration motor 7 is located below the crossbar 3. The electric push rod 2 and the vibration motors 7 are both connected to the controller, which and the battery are embedded in the chassis 1. Each time concrete is poured into the cone 5, the vibration motors 7 of one layer will be activated to ensure that the surface of the concrete poured each time is flush.

[0029] Please see Figure 1-6Inside the upper limiting ring 6, a movable ring 8 is rotatably installed. A shaft ring 9 is fixedly installed on the side of the movable ring 8. Inside the shaft ring 9, a shaft rod 10 is rotatably installed. A scraper 11 is fixedly installed on the top of the shaft rod 10. The scraper 11 is rotatably connected to the top of the cone 5 through the movable ring 8, shaft ring 9, shaft rod 10 and limiting ring 6. Before pouring concrete, the scraper 11 can be rotated to offset it so as not to obstruct the concrete from being poured into the cone 5. After that, the scraper 11 can be rotated to scrape off the concrete at the top of the cone 5.

[0030] Please see Figure 1-6 Inside the lower limiting ring 6, a movable ring 12 is rotatably mounted, and a scraper 13 is fixedly mounted on the outer side of the movable ring 12. There are four scraper 13s arranged in a ring. Fallen concrete will land on the chassis 1, so it needs to be removed, otherwise it will affect the concrete collapse. By driving the scraper 13 to rotate, the scraper 13 can collect the concrete on the chassis 1 for easy removal.

[0031] Please see Figure 1-6 The side of the chassis 1 is provided with a mounting groove 14, and a level 15 is embedded in the mounting groove 14 for observing the tilt angle of the chassis 1. A transparent plastic plate 16 is embedded in the opening of the mounting groove 14 to prevent concrete from entering the mounting groove 14 without affecting the viewing of the level 15.

[0032] Please see Figure 1-6 A threaded cylinder 17 is fixedly installed at the bottom of the chassis 1. A threaded post 18 is threadedly connected inside the threaded cylinder 17. A pad 19 is movably installed at the bottom of the threaded post 18. By driving the threaded post 18 to rotate, the threaded post 18 can extend into or out of the threaded cylinder 17, and the pad 19 can then be adjusted in height to ensure the horizontal height difference of the chassis 1.

[0033] Working principle: When in use, after concrete is poured into the cone 5, the scraper 11 is manually rotated to scrape the concrete at the top of the cone 5 to level it. The scraper 13 is manually rotated to collect and clean the concrete that falls onto the chassis 1. Both methods quickly remove or clean the concrete.

[0034] Four sets of vibration motors 7 are set up, with three in each set, arranged at equal intervals from top to bottom. After each pour of concrete, one set of vibration motors 7 is started to run. The vibration force can level the concrete inside the cone 5 until the concrete fills the entire cone 5. During this process, no manual vibration is required, which improves the testing efficiency.

[0035] Based on the bubble offset in the level 15, the threaded column 18 under the base 1 is rotated. The threaded column 18 extends into or out of the threaded cylinder 17, and the pad 19 moves up or down until the bubble in the level 15 is centered, thereby adjusting the horizontal height difference of the base 1 and reducing the discrepancy in the concrete test data.

[0036] Finally, the output end of the electric push rod 2 extends, and the crossbar 3 moves upward. Then the cone 5 moves upward. Without the restraint of the cone 5, the concrete will collapse. During this process, personnel need to calculate the time and then use a measuring ruler to detect the height of the collapsed concrete.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
