[0002] Concrete is a widely used building material in construction engineering. To improve concrete performance and reduce costs, admixtures are often added. However, the type and dosage of admixtures affect the strength of the concrete, thus requiring accurate testing of the strength of admixture-based concrete.

[0003] During testing, concrete specimens need to be positioned to ensure the accuracy of the test data. Due to the different sizes and shapes of concrete specimens, non-adjustable and uniformly shaped positioning clamps cannot meet the stable positioning requirements for specimens of different specifications, thus limiting their applicability. In view of the above reasons, this application proposes a strength testing device based on admixture concrete. Utility Model Content

[0035] Example 1

[0036] like Figure 1-4 As shown, the present invention proposes a strength testing device based on admixture concrete, comprising a base 1, two sets of sliding grooves on the top of the base 1, a top plate 3 for installation fixed above the base 1, multiple support rods 2 fixed on the top of the base 1, the bottom of the top plate 3 and the top of the support rods 2 fixedly connected, a hydraulic cylinder 4 fixed on the top of the top plate 3, a pressure sensor 6 for detection at the output end of the hydraulic cylinder 4, multiple connecting rods fixed on the top of the pressure sensor 6, the same connecting plate 5 fixed on the top of the multiple connecting rods, the top of the connecting plate 5 and the output end of the hydraulic cylinder 4 fixedly connected, and a fixing structure 7 for positioning the specimen on the top of the base 1.

[0037] The fixing structure 7 includes two upright plates 701 for installation and a threaded rod 702 movably connected to them. The upright plates 701 have through holes with threads on their inner walls. The threaded rod 702 is adapted to the threads on the inner walls of the through holes. A flat clamping plate 703 for positioning is movably mounted at one end of the threaded rod 702. A guide block is fixedly mounted on one side of the flat clamping plate 703, and a mounting hole is provided on one side of the guide block. A bearing is fixedly mounted in the mounting hole, and the inner ring of the bearing is fixedly fitted onto the threaded rod 702. Multiple grooves 704 are provided on one side of the flat clamping plate 703. The multiple grooves 704 can hold uneven parts of the outer wall of the specimen, enhancing the positioning accuracy of some corners. A slot 706 is provided at the top of the flat clamping plate 703, and two sliders 705 are fixedly mounted at the bottom of the flat clamping plate 703. The sliders 705 and the grooves are movably connected. Next, the flat clamping plate 703 is provided with an arc-shaped clamping plate 708, which can be used to position the specimen with an arc-shaped outer wall. The outer wall of the arc-shaped clamping plate 708 is fixedly provided with an insert 707, which is compatible with the slot 706. The top of the flat clamping plate 703 is provided with a mounting bracket 709, and a baffle 710 for blocking is movably provided inside the mounting bracket 709. The top of the mounting bracket 709 is provided with a first rectangular slot 711 and a second rectangular slot 712. The top of the baffle 710 is provided with a storage groove 713, and a first spring 714 is fixedly provided inside the storage groove 713. A top block 715 is fixedly provided on the top of the first spring 714. The top block 715 is movably connected to the storage groove 713. Limiting grooves are provided on both inner walls of the storage groove 713. Limiting blocks are fixed on both sides of the top block 715. The limiting blocks are movably connected to the limiting grooves.

[0038] In this embodiment, before positioning the specimen, the arc-shaped clamping plate 708 is selectively installed according to the shape of the specimen. If the side wall of the specimen is relatively flat, the two threaded rods 702 are directly rotated, and the threaded rods 702 drive the two flat clamping plates 703 to move closer together, clamping and fixing the specimen. The setting of multiple grooves 704 can enhance the positioning of some corners. If the side wall of the specimen is not flat and is arc-shaped, the top block 715 is pressed inward, and the top block 715 compresses the spring 714. When the top block 715 retracts into the storage groove 713 and the top of the top block 715 is in contact with the top inner wall of the mounting bracket 709, the baffle 710 is pulled backward. The baffle 710 drives the top block 715, and when the top block 715... 5. When the device moves to the position of rectangular slot 2 712, spring 1 714 presses the top block 715 to pop it out of rectangular slot 2 712, thus positioning the baffle 710. At this time, the baffle 710 is offset from the slot 706. Then, the insert 707 is inserted into the slot 706. The top block 715 is pressed down again, and the baffle 710 is pulled forward. When the top block 715 moves to the position of rectangular slot 1 711, spring 1 714 presses the top block 715 to pop it out of rectangular slot 1 711, thus positioning the baffle 710. At this time, the bottom of the baffle 710 and the top of the insert 707 are in contact, thus fixing the insert 707 and completing the installation of the arc-shaped clamp 708.

[0039] Example 2

[0040] like Figure 1 and Figure 5 As shown, based on Embodiment 1, the connecting plate 5 is provided with a protective structure 8 for blocking debris. The protective structure 8 includes an outer cover 801, and a receiving cavity 802 is provided at the bottom of the outer cover 801. Multiple springs 803 are fixedly installed inside the receiving cavity 802. The bottom of the multiple springs 803 is fixedly installed with the same inner cover 804. Sliding blocks 805 are fixedly installed on both sides of the inner cover 804. The sliding blocks 805 are movably connected to the inner wall of the receiving cavity 802. During the testing process, the connecting plate 5 drives the outer cover 801 to move down. The movement of the outer cover 801 causes the inner cover 804 to move inside the receiving cavity 802. Under the action of the springs 803, the bottom of the inner cover 804 is always in contact with the base 1, which can effectively prevent the specimen from breaking and debris from splashing and injuring people during the testing process, thus improving the safety of the equipment.

[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
