Description

Technical Field

[0001] This invention relates to the field of building material testing technology, and in particular to a load-bearing capacity testing device for lightweight walls. Background Technology

[0002] Lightweight phase change energy storage walls, as a type of lightweight wall structure, typically use lightweight concrete, foamed inorganic substrates, light steel composite panels, or hollow lightweight walls as the matrix, integrating encapsulated phase change energy storage materials internally. They offer advantages such as light weight, high degree of modularity, heat storage and temperature regulation within the wall, and reduced building energy consumption. However, lightweight phase change energy storage walls are often used in various harsh environments, therefore, their load-bearing capacity needs to be tested to ensure their safety and reliability in practical applications.

[0003] In related technologies, small load blocks are often arranged in a horizontal and vertical distributed manner, or large load blocks are arranged in a single row. The method of applying loads to lightweight walls to test their load-bearing capacity involves several steps. When applying loads to lightweight walls using small load blocks, they must be placed one by one at intervals until the target number of small load blocks are all placed on the wall. This process is time-consuming, and the area to be loaded will be temporarily unloaded, while the area with placed small load blocks will experience localized stress, affecting the overall load-bearing capacity of the lightweight wall and reducing the accuracy and reliability of the test results. When applying loads to lightweight walls using large load blocks, a direct, whole-piece placement method is used to apply surface loads to the wall, achieving synchronous and uniform stress distribution across the loaded area. However, large load blocks have fixed specifications, limited adaptability, and cannot be matched to different wall widths, resulting in poor versatility. Summary of the Invention

Detailed Implementation

[0019] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0020] The load-bearing capacity testing device for lightweight walls according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0021] The load-bearing capacity testing device for lightweight walls according to embodiments of the present invention, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it may include: load assembly 1, first triaxial displacement module 7, second triaxial displacement module 9 and rotation device 10.

[0022] The load assembly 1 includes multiple load blocks 2 connected in sequence. Each load block 2 includes a pressure block 3 and a telescopic rod 4. The pressure block 3 is rotatably provided with a rotating shaft 5 and has a swing groove 6. One end of the telescopic rod 4 extends into the swing groove 6 and is connected to the rotating shaft 5. The other end of the telescopic rod 4 is detachably connected to the adjacent pressure block 3. The telescopic rod 4 is configured to rotate with the rotating shaft 5, causing the adjacent pressure block 3 connected to the telescopic rod 4 to fold and rotate relative to each other around the axis of the rotating shaft 5.

[0023] For example, the number of load blocks 2 (200mm × 200mm × 50mm) in load assembly 1 can be even (e.g., 8 blocks), suitable for standard test specimens of lightweight walls with a width of 950mm to 1000mm, with a spacing of 40mm between load blocks 2. When using load assembly 1, the 8 load blocks can be folded into a 4-row, 2-column configuration.

[0024] A first electromagnet ring 8 is provided on the drive end of the first three-axis displacement module 7, and the first electromagnet ring 8 is magnetically connected to the pressure block 3. A second three-axis displacement module 9 is provided on the drive end of the first three-axis displacement module 7.

[0025] The rotating device 10 is installed on the drive end of the second three-axis displacement module 9. The rotating device 10 is equipped with a second electromagnet ring 11 and a third electromagnet ring 12. The second electromagnet ring 11 is magnetically connected to the pressure block 3, and the third electromagnet ring 12 is magnetically connected to the rotating shaft 5.

[0026] The rotating device 10 is configured to drive the rotating shaft 5 to rotate via the third electromagnet ring 12, so that the telescopic rod 4 rotates around the axis of the rotating shaft 5. The second three-axis displacement module 9 is configured to control the movement of the rotating device 10 to rotate the target number of rotating shafts 5, so as to adjust the number of rows and columns of load blocks 2 in the load assembly 1.

[0027] It should be noted that the target quantity and the number of rows and columns of the load blocks 2 are related. For example, two rows and two columns require the rotation of the shafts 5 on the two load blocks 2.

[0028] Specifically, if the dimensions of the lightweight wall to be tested correspond to the multiple vertically arranged pressure blocks 3 inside the load assembly 1, the first triaxial displacement module 7 controls the first electromagnet ring 8 to magnetically connect with the head pressure block 3 of the load assembly 1, and the second triaxial displacement module 9 controls the second electromagnet ring 11 to magnetically connect with the tail pressure block 3 of the load assembly 1 through the rotating device 10. The first triaxial displacement module 7 and the second triaxial displacement module 9 cooperate with each other to place the load assembly 1 directly on the target position of the lightweight wall.

[0029] If the dimensions of the lightweight wall to be tested do not correspond to the multiple vertically arranged pressure blocks 3 within the load assembly 1 (for example, ... Figure 10 The dimensions of the vertically arranged multiple pressure blocks 3 shown exceed the dimensions of the lightweight wall. Before placing the load assembly 1, the second triaxial displacement module 9 can adjust the number of rows and columns of the multiple load blocks 2 in the load assembly 1 through the third electromagnet ring 12.

[0030] The second three-axis displacement module 9 controls the third electromagnet ring 12 to be magnetically connected to the rotating shaft 5 on the preceding pressure block 3 of the pressure block 3 to be adjusted. The rotating device 10 controls the rotation of the rotating shaft 5 through the third electromagnet ring 12, and the rotating shaft 5 drives the pressure block 3 to be adjusted to rotate through the telescopic rod 4. This is based on the arrangement of the multiple load blocks 2 within the load assembly 1, including the number of rows and columns (e.g., ...). Figure 11 As shown in the two rows and two columns, the corresponding number of pressure blocks 3 are adjusted. The first three-axis displacement module 7 and the second three-axis displacement module 9 work together to place the adjusted load assembly 1 directly onto the target position of the lightweight wall. It should be noted that it can also be quickly adjusted directly on the lightweight wall.

[0031] The telescopic rods 4 between the pressure blocks 3 can easily adjust the spacing between them. A reasonable spacing between the pressure blocks 3 is conducive to uniform load distribution. At the same time, by changing the number of rows and columns of multiple load blocks 2 in the load assembly 1, it can adapt to lightweight walls of different sizes, improve the applicability of the load assembly 1, eliminate the need to customize corresponding load blocks 2 for lightweight walls, and reduce testing costs.

[0032] Furthermore, such as Figure 6 and Figure 7 As shown, the first three-axis displacement module 7 includes: a first lead screw drive device, a second lead screw drive device, and a first hydraulic telescopic device. The second lead screw drive device is located at the drive end of the first lead screw drive device, the first hydraulic telescopic device is located at the drive end of the second lead screw drive device, and the first electromagnet ring 8 is located at the drive end of the first hydraulic telescopic device. The first lead screw drive device and the second lead screw drive device are configured to control the first electromagnet ring 8 to move horizontally, and the first hydraulic telescopic device is configured to control the first electromagnet ring 8 to move vertically.

[0033] The second three-axis displacement module 9 includes: an electric push rod, a third lead screw drive device, and a second hydraulic telescopic device. The electric push rod is located at the drive end of the second lead screw drive device, the third lead screw drive device is located at the drive end of the electric push rod, the second hydraulic telescopic device is located at the drive end of the third lead screw drive device, and the rotating device 10 is located at the drive end of the second hydraulic telescopic device. The electric push rod and the third lead screw drive device are configured to control the horizontal movement of the rotating device 10, and the second hydraulic telescopic device is configured to control the vertical movement of the rotating device 10.

[0034] Visual positioning sensors are respectively installed on the drive end (first hydraulic telescopic device) of the first three-axis displacement module 7 and the drive end of the second three-axis displacement module 9 (second hydraulic telescopic device).

[0035] Furthermore, a swing groove 6 is provided at the intersection of two adjacent side walls on the pressure block 3, and the inner side wall of the swing groove 6 is in contact with the telescopic rod 4. A rotating groove 13 is provided on the pressure block 3, and the rotating groove 13 is connected to the swing groove 6. The rotating shaft 5 is set in the rotating groove 13 through a bearing.

[0036] It should be noted that the top of the rotating shaft 5 described in this embodiment is lower than the top of the rotating groove 13, so that there is no protrusion on the upper surface of the pressure block 3, which facilitates the stacking of the pressure block 3.

[0037] The swing groove 6 has only two inner sidewalls, which are connected and the included angle between them is 90°.

[0038] To clearly illustrate the previous embodiment, in one embodiment of the present invention, as follows: Figure 5 and Figure 6 As shown, the rotating device 10 may include a drive motor 38 and a rotating plate 39. The drive motor 38 is mounted on the second three-axis displacement module 9, and the rotating plate 39 is mounted on the drive end of the drive motor 38. The second electromagnet ring 11 and the third electromagnet ring 12 are respectively mounted on the lower end of the rotating plate 39. The diameter of the third electromagnet ring 12 is smaller than the diameter of the second electromagnet ring 11, and the lower end face of the third electromagnet ring 12 is located below the lower end face of the second electromagnet ring 11.

[0039] It should be noted that the third electromagnet ring 12 described in this embodiment can be inserted into the rotating groove 13 and magnetically connected to the rotating shaft 5.

[0040] In one embodiment of the present invention, such as Figure 2 and Figure 3 As shown, the telescopic rod 4 may include: a fixed barrel 14, a movable rod 15, an arc plate 16, and a locking post 17. The fixed barrel 14 is sleeved on the movable rod 15. The arc plate 16 is connected to the fixed barrel 14 through an elastic element 18. The locking post 17 is disposed on the arc plate 16. Multiple locking holes 19 are provided on the side wall of the movable rod 15, and the locking post 17 is engaged with the locking holes 19.

[0041] It is understood that the movable rod 15 described in this embodiment can slide on the fixed barrel 14. The arc plate 16 pulls the locking pin 17 to separate from the locking hole 19. After the movable rod 15, which has lost its limit, slides on the fixed barrel 14 to the target position, it no longer applies external force to the arc plate 16. The elastic element 18 (e.g., spring) rebounds and drives the locking pin 17 to reset through the arc plate 16, so that the locking pin 17 engages with the target locking hole 19. The distance between the two pressure blocks 3 can be adjusted by adjusting the length of the movable rod 15 outside the fixed barrel 14.

[0042] In one embodiment of the present invention, such as Figure 1 and Figure 5As shown, the first three-axis displacement module 7 is provided with a frame plate 20 with an upper opening. An electric telescopic component 40 is provided on the frame plate 20. An electromagnet block 21 is provided on the drive end of the electric telescopic component 40. The electromagnet block 21 is magnetically connected to the arc plate 16. The load block 2 can pass through the hollow area of ​​the frame plate 20.

[0043] It is understood that when the first three-axis displacement module 7 and the second three-axis displacement module 9 described in this embodiment drive the load block 2 to pass through the frame plate 20, the electric telescopic component 40 can drive the electromagnet block 21 to magnetically connect with the arc plate 16. By pushing and pulling the arc plate 16, the spacing between the pressure blocks 3 can be adjusted during the movement of the pressure blocks 3, thereby improving the adjustment efficiency.

[0044] In one embodiment of the present invention, such as Figure 3 As shown, the pressure block 3 has a groove 22, and the moving rod 15 is engaged with the groove 22. The moving rod 15 has a through groove 23, and the pressure block 3 has a connecting groove 24, which communicates with the groove 22. A retaining plate 25 is provided in the connecting groove 24, and the retaining plate 25 is engaged with the through groove 23. The side wall of the retaining plate 25 is provided with an elastic layer (e.g., a rubber layer). A third electromagnet block 21 is provided on the drive end of the rotating device 10, and the retaining plate 25 is magnetically connected to the third electromagnet block 21. The friction between the elastic layer and the connecting groove 24 limits the retaining plate 25, preventing the retaining plate 25 from separating from the connecting groove 24 without external force.

[0045] It should be noted that the load-bearing capacity test of the lightweight wall needs to be carried out by increasing the load in stages from both sides to the middle. After adjusting the number of rows and columns of multiple load blocks 2 in the load component 1, it can be adapted to the size of the lightweight wall, but it is not necessary to increase too much load at once. The second three-axis displacement module 9 controls the magnetic connection between the third electromagnet block 21 and the card plate 25 on the pressure block to be separated 3, pulls the card plate 25 upward, so that the card plate 25 is separated from the through groove 23, moves the remaining pressure blocks 3 (other pressure blocks 3 except the pressure block to be separated 3), and separates the pressure block to be separated 3.

[0046] It should be noted that, since the load is applied to the wall in batches starting from both sides of the wall, the first three-axis displacement module 7, the first electromagnet ring 8, the second three-axis displacement module 9, the rotating device 10, the second electromagnet ring 11, the third electromagnet ring 12, the frame plate 20, the electromagnet, and the electric telescopic component 40 are symmetrically arranged in twos.

[0047] Furthermore, a placement chamber 26 is provided below the first three-axis displacement module 7. Multiple load components 1 are placed within the placement chamber 26. An adjustment platform 27 is provided on the side wall of the placement chamber 26, and a conveyor belt 28 is mounted on the adjustment platform 27. A guide plate 29 is also provided on the side wall of the adjustment platform 27. The adjustment platform 27 is used to receive the load components 1, facilitating the adjustment of the number of rows and columns of the load components 1. When it is necessary to separate excess blocks, the separated blocks are moved to the guide plate 29 via the conveyor belt 28, without affecting the subsequent adjustment of the load components 1.

[0048] In one embodiment of the present invention, such as Figure 8 and Figure 9 As shown, it may also include: a wall support component 30, which includes: a base 31, a left and right rotary screw module 32, and two support frames 33. The left and right rotary screw module 32 is mounted on the base 31, and the two support frames 33 are respectively mounted on the two output ends of the left and right rotary screw module 32. An environmental simulation component 34 is mounted on the base 31. The environmental simulation component 34 includes: two symmetrically arranged environmental simulation boxes 35. The inner walls of the environmental simulation boxes 35 are respectively provided with integrated cooling and heating plates. A limit slider 36 is provided at the bottom of the environmental simulation box 35. A limit groove 37 is provided on the base 31. The limit slider 36 is slidably connected to the limit groove 37. The two environmental simulation boxes 35 enclose an environmental simulation space, and the two support frames 33 are arranged in the environmental simulation space.

[0049] By setting up complex environments such as high and low temperatures and thermal cycling, the system simulates the non-ideal service scenarios of lightweight walls in emergency housing, field facilities, and other applications, obtaining data on the load-bearing capacity decay of the lightweight walls. This provides data support for the safe application of lightweight walls in various special scenarios. Depending on the testing requirements, the corresponding integrated cooling and heating panel inside the environmental simulation chamber 35 can be opened. For example, if temperature simulation is required on the side wall of the lightweight wall, only the integrated cooling and heating panel near the wall needs to be opened. The environmental simulation component 34 adopts a split design, facilitating the placement of the lightweight wall on the support frame 33 and also facilitating the placement of the load component 1. Temperature simulation can be performed before or during the application of load.

[0050] It should be noted that the motors described in the above embodiments (e.g., drive motor 38, motor in the lead screw drive device, etc.) are equipped with brakes, which can make the motor stop running quickly. A gearbox is provided on the drive end of the motor, and the drive end of the motor is connected to the input end of the gearbox. The output end of the gearbox constitutes the drive end of the motor, and the speed of the motor output is adjusted by the gearbox.

[0051] In summary, the load-bearing capacity testing device for lightweight walls according to the present invention can be adapted to walls of various sizes. By quickly applying loads, it avoids local stress on the wall during placement, ensuring accurate and reliable test results.
