Description

Technical Field

[0002] With the rapid development of the construction industry, the performance requirements for building materials are also increasing. Concrete, as one of the most commonly used and important materials in the construction industry, directly affects the safety, durability, and overall efficiency of buildings. Therefore, how to accurately and efficiently test the physical and mechanical properties of concrete has become a focus for researchers and engineers. With the increasing awareness of environmental protection and the popularization of sustainable development concepts, expanded shale lightweight aggregate concrete, as a green, lightweight, and high-performance building material, has gradually gained attention. Expanded shale lightweight aggregate concrete has good thermal insulation, heat preservation, fire resistance, and seismic resistance properties, and is widely used in high-rise buildings, long-span bridges, and special structures. However, due to its special material composition and structural characteristics, traditional testing methods are not entirely suitable for the performance evaluation of expanded shale lightweight aggregate concrete.

[0003] Traditional concrete performance testing methods rely heavily on manual operations, including sampling, specimen preparation, and compression or tensile testing. These methods are not only time-consuming and labor-intensive, but also prone to errors and uncertainties due to human factors and environmental conditions. Furthermore, for on-site cast concrete structures, traditional methods struggle to achieve real-time monitoring, making it difficult to promptly detect and address potential quality issues, which could lead to safety hazards.

[0004] Therefore, it is necessary to propose a performance testing instrument for expanded shale lightweight aggregate concrete to solve the above problems. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1

[0029] Please see Figure 3 and 4 An expandable shale lightweight aggregate concrete performance testing instrument includes a housing 1. A base 2 is movably connected to the lower inner side of the housing 1. A turntable 3 is rotatably connected to the upper end of the base 2. A toothed groove 4 is formed on the inner side of the turntable 3. A first motor 5 is fixedly installed on the inner side of the base 2. A gear 6 is fixedly connected to one end of the output shaft of the first motor 5. The gear 6 meshes with the toothed groove 4. A recessed hole 7 is formed on one side of the turntable 3. A telescopic rod 8 is fixedly installed inside the recessed hole 7. Multiple fixed plates 9 arranged in a ring array are symmetrically fixedly connected to one side of the turntable 3. A hook 10 is rotatably connected between two adjacent fixed plates 9. A coil spring 11 is fixedly connected to both sides of the hook 10.

[0030] In this embodiment, the smooth and precise rotation of the turntable 3 can be achieved through the cooperation of the toothed groove 4, the first motor 5 and the gear 6. This design ensures that the concrete column material to be tested can rotate evenly and stably on the turntable, which helps to improve the accuracy and repeatability of the test. The combination of the telescopic rod 8, the fixing plate 9, the hook 10 and the disc spring 11 can firmly and stably clamp the concrete column material to be tested. This clamping method not only prevents the material from shifting or shaking during the test, but also adapts to concrete columns of different diameters or shapes, improving the adaptability and versatility of the device. Through the extension and retraction adjustment of the telescopic rod 8, combined with the synergistic effect of the fixing plate 9, the hook 10 and the disc spring 11, stable gripping of the material is achieved.

[0031] The combination of the rotation of turntable 3 and the clamping mechanism makes the testing process more automated and convenient. Operators only need to place the material to be tested on the turntable and start the device to complete the test, which greatly saves time and labor. At the same time, stable clamping and precise rotation also help improve the accuracy and reliability of the test data.

[0032] Example 2

[0033] Please see Figure 1 and 5 This embodiment is a further optimization based on embodiment 1. Specifically, a hydraulic cylinder 12 is fixedly connected to the upper end of the housing 1. The bottom end of the hydraulic cylinder 12 penetrates the upper surface of the housing 1 and is fixedly connected to a connecting plate 14. A first threaded block 15 is fixedly connected to the middle of the bottom end of the connecting plate 14. A first movable plate 16 is movably connected to the lower end of the connecting plate 14. A second motor 17 is fixedly installed inside the first movable plate 16. A first screw 18 is fixedly connected to one end of the output shaft of the second motor 17. The first screw 18 is adapted to the first threaded block 15. The first movable plate... A second threaded block 19 is fixedly connected to the middle of the bottom end of the first movable plate 16. A second movable plate 20 is movably connected to the lower end of the first movable plate 16. A third motor 21 is fixedly installed inside the second movable plate 20.

A detection head 24 and a pressing head 25 are fixedly installed on one side of the rotating block 23. The detection head 24 and the pressing head 25 are distributed at 90°.

[0034] In this embodiment, the lifting and moving of the second movable plate 20 and the rotating block 23 can be achieved through the coordinated use of the hydraulic cylinder 12, the connecting plate 14, the first threaded block 15, the second motor 17, the first screw 18, and the third motor 21 and the second screw 22. This design enables the detection head 24 to detect concrete columns at different heights and positions, thereby gaining a more comprehensive understanding of the material's properties. Specifically, by utilizing the lifting function of the hydraulic cylinder 12, combined with the precise transmission of the threaded block and the screw, multi-position adjustment is achieved. By utilizing the precise transmission of the first threaded block 15, the second motor 17, the first screw 18, the second threaded block 19, the third motor 21, and the second screw 22, the rotating block 23 can be finely adjusted in the horizontal and vertical directions. This flexibility allows the operator to adjust the position of the detection head 24 according to actual needs to obtain the most accurate detection data.

[0035] The detection head 24 and the pressing head 25, which are fixedly installed on one side of the rotating block 23, are distributed at 90°, so that the same rotating block can perform different functions of detection simultaneously or separately. This design not only improves the detection efficiency, but also increases the versatility of the device, enabling the same device to complete a variety of detection tasks.

Pressure sensors 13 are fixedly installed on the inner side of the plurality of grooves 26, located between the bottom inner side of the base 2 and the housing 1.

[0038] In this embodiment, pressure sensors 13 are installed inside multiple grooves 26 at the bottom of the base 2, allowing for real-time monitoring of the weight of objects placed on the turntable. This design enables operators to directly obtain the weight information of the concrete column material to be tested, providing an important basis for subsequent load-bearing capacity calculations. The accurate weight data provided by the pressure sensors 13 helps to more precisely calculate the load-bearing capacity of the concrete column material, allowing for a more comprehensive evaluation of the material's performance.
