Description

Technical Field

[0001] This invention relates to the field of wall strength testing technology, specifically to a building construction wall strength testing device. Background Technology

[0002] Wall strength testing refers to the use of an in-situ pressure tester to perform on-site compressive strength testing on post-construction building walls (such as masonry walls, concrete walls, etc.). Its core principle is to measure the failure load and deformation characteristics of the wall under pressure by applying stable axial pressure, and then calculate the actual compressive strength or bearing capacity of the wall by combining the material mechanics formulas. The testing process does not move the wall components and is completed directly in the original location of the building, avoiding damage to the structure caused by sampling tests.

[0003] A search revealed that CN117091948A discloses a strength testing device for prefabricated building wall panels, comprising a fixing unit and a testing unit. The fixing unit secures reinforced concrete wall panels that meet testing standards in terms of size, shape, and flatness of edges and corners. The testing unit applies pressure to the center of the reinforced concrete wall panel and simultaneously records the bending deformation of the panel on an unfolded paper roll using ink, which is then measured with a ruler. The bending strength is then calculated using a formula based on the bending height and the central pressure test force, combined with the panel's own data. Throughout the process, no expensive precision instruments are used, thus reducing the cost for small factories to conduct bending tests on reinforced concrete wall panels.

[0004] The existing wall strength testing equipment still has the following defects: (1) Traditional equipment relies on a single support frame, and when loaded, it is easy to cause lateral displacement due to uneven wall or eccentric force, resulting in distorted test data; There are limitations to pre-grooving; it can only be used to test wall structures that have been pre-grooved or have pre-drilled holes. When encountering scenarios where grooving is not suitable, such as lightweight partition walls, beams, or ancient building walls, the testing equipment needs to be replaced to complete the measurement. Summary of the Invention

[0005] The purpose of this invention is to provide a wall strength testing device for building construction, which solves the problems existing in the existing wall strength testing devices.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a wall strength testing device for building construction, comprising an anti-deviation rod, and further comprising: The detection module 1 and the detection module 2 each include a base, a transmission module, an adjustable clamping module, and a telescopic module. The base surface is provided with a hidden groove, and the adjustable clamping module and the telescopic module are both disposed in the hidden groove.

Both the transverse and longitudinal transmission components consist of two sets of transmission sleeves and gears fixedly disposed on the surface of the transmission sleeves. The two sets of gears in the transverse and longitudinal transmission components are connected by transmission. One end of the rotating rod and the threaded rod are respectively sleeved in the two sets of transmission sleeves in the transverse transmission component.

[0010] As a further embodiment of the present invention, the driving module includes a first driving rod and a second driving rod, which are respectively sleeved in two sets of transmission sleeves in the longitudinally placed transmission component.

The main lifting frame is disposed inside the rotating frame, and the secondary lifting frame is disposed at the bottom of the main lifting frame. The bases of the detection module one and the detection module two are slidably connected to the upper surfaces of the main lifting frame and the secondary lifting frame, respectively. The main lifting frame is provided with a horizontal guide rail one and a horizontal guide rail two on its longitudinal side and horizontal side, respectively.

[0013] As a further embodiment of the present invention, a horizontally movable frame is provided inside the flat guide rail, the surface of which is provided with mounting hole one and mounting hole two, two sets of anti-deviation rods pass through mounting hole one and can be connected inside the horizontal guide rail two, and driving rod one and driving rod two pass through mounting hole two.

[0014] The beneficial effects of the present invention are: (1) The present application can not only automatically and accurately send the detection module one and the detection module two into the pre-made hole, but also control the clamping parts in the detection module one and the detection module two to clamp the wall horizontally while ensuring that the distributed hydraulic loading module is in the middle position of the pre-made hole.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] Please see Figures 1 to 12 In one embodiment of the present invention, a wall strength testing device for building construction includes an anti-deviation rod 9, and further includes: The detection module 1 (2) and the detection module 2 (3) each include a base 21, a transmission module 23, an adjustable clamping module 24, and a telescopic module 25. The base 21 has a hidden groove 211 on its surface. The adjustable clamping module 24 and the telescopic module 25 are both located in the hidden groove 211. The transmission module 23 is located at one end of the base 21. The adjustable clamping module 24 and the telescopic module 25 are both connected to the lateral side of the transmission module 23. The base 21 has four sets of reference holes 212 symmetrically arranged on its surface. The anti-deviation rod 9 connects two sets of reference holes 212 on the surface of the base 21 in series. The detection module 2 also includes a distributed hydraulic loading module 22 and a laser sensor. The distributed hydraulic loading module 22 includes several sets of micro hydraulic cylinders. The micro hydraulic cylinders integrate pressure sensors and displacement sensors. The laser sensors are symmetrically arranged at both ends of the base 21 (not shown in the figure). The drive module 5 is connected to the longitudinal side of the transmission module 23. The drive module 5 controls the adjustable clamping module 24 and the telescopic module 25 to perform rotational and linear motions respectively through the transmission module 23.

[0031] Please see Figures 3 to 6 Furthermore, the adjustable clamping module 24 includes a clamping member 241 and a rotating rod 242. The clamping member 241 is a clamping block fixedly disposed on the surface of the sleeve. The inner side of the sleeve is movably sleeved on the surface of the rotating rod 242. The two sets of clamping blocks are symmetrically distributed on both sides of the distributed hydraulic loading module 22.

[0032] Please see Figures 3 to 6 Furthermore, the telescopic module 25 includes a bidirectional moving part 251 and a threaded rod 252. The threaded rod 252 is a bidirectional screw. The bidirectional moving part 251 includes a nut seat and a bracket. The bracket is fixedly connected to the nut seat. The nut seat is threadedly connected to the surface of the threaded rod 252. The outer side of the sleeve is connected to the surface of the bracket. One end of the rotating rod 242 and the threaded rod 252 are both connected to the lateral side of the transmission module 23.

[0033] Please see Figures 3 to 6 Furthermore, the transmission module 23 includes a transverse transmission component 231 and a longitudinal transmission component 232. Both the transverse transmission component 231 and the longitudinal transmission component 232 are composed of two sets of transmission sleeves and gears fixedly disposed on the surface of the transmission sleeves. The two sets of gears in the transverse transmission component 231 and the longitudinal transmission component 232 are connected for transmission. One end of the rotating rod 242 and the threaded rod 252 are respectively sleeved in the two sets of transmission sleeves in the transverse transmission component 231.

[0034] Please see Figures 3 to 6Furthermore, the drive module 5 includes a first drive rod 51 and a second drive rod 52. The first drive rod 51 and the second drive rod 52 are respectively sleeved in two sets of transmission sleeves in the longitudinal transmission member 232. The rotating rod 242, the threaded rod 252, the first drive rod 51 and the second drive rod 52 and the transmission sleeve, as well as the sleeve and the rotating rod 242, are all keyed and keyway mating structures. The first drive rod 51 and the second drive rod 52 are driven by two independent drive motors, which can simultaneously control the movement of the two sets of transmission modules 23, the adjustable clamping module 24 and the telescopic module 25.

[0035] In this embodiment of the invention, the surface of the clamping block is integrated with a flexible layer and a pressure sensor. The pressure sensor is used to monitor the magnitude of the clamping force to prevent excessive clamping force from damaging the vulnerable material of the wall surface. The flexible layer plays an auxiliary protective role.

[0036] Please see Figures 3 to 7 In another embodiment of the present invention, a mobile vehicle body 1 and a rotating frame 6 are also included, wherein the rotating frame 6 is connected to the mobile vehicle body 1 via a rotating shaft 61.

[0037] Please see Figure 1 , Figures 7 to 9 Furthermore, it also includes a main lifting frame 7 and a secondary lifting frame 8. The main lifting frame 7 is disposed inside the rotating frame 6, and the secondary lifting frame 8 is disposed at the bottom of the main lifting frame 7. The base 21 of the detection module 1 2 and the detection module 2 3 are slidably connected to the upper surfaces of the main lifting frame 7 and the secondary lifting frame 8, respectively. The main lifting frame 7 is provided with a horizontal guide rail 1 71 and a horizontal guide rail 2 72 on its longitudinal side and horizontal side, respectively.

[0038] Please see Figure 1 , Figures 7 to 9 Furthermore, it also includes a horizontal moving frame 4 disposed within a horizontal guide rail 71. The surface of the horizontal moving frame 4 is provided with mounting holes 41 and 42. Two sets of anti-deviation rods 9 pass through the mounting holes 41 and can be connected within the horizontal guide rail 72. The drive rods 51 and 52 pass through the mounting holes 42.

[0039] In this embodiment of the invention, the rotating shaft 61 is connected to the driving device to realize intelligent adjustment of the tilt angle of the rotating frame 6. Both the main lifting frame 7 and the auxiliary lifting frame 8 have their lifting height precisely controlled by an electric telescopic rod. The surface of the horizontal guide rail is provided with toothed grooves, which are used to connect to the drive gear. The drive gear controls the movement of the horizontal moving frame 4 through the toothed grooves. This not only enables automatic detection of building walls with prefabricated holes at different tilt angles, but also... (Refer to the attached...) Figure 12 It can also automatically detect building walls without pre-drilled holes (such as beams, cantilever beams, and other building structures).

[0040] In its initial state, apart from the two anti-deviation rods 9 that have been removed (referring to the anti-deviation rods 9 that failed to connect to the mounting holes 41 of the horizontal moving frame 4), all other components of the equipment are housed within the mobile vehicle body 1 with the pivot 61 as the axis. When inspecting a building construction wall, the specific steps include: S100, Reference Appendix Figure 9 Move the mobile vehicle 1 to the wall, and then adjust it by rotating it by the corresponding angle around the axis 61 according to the tilt angle of the wall. The figure shows an example of a wall perpendicular to the ground. At this time, rotate the detection device by 90 degrees around the axis 61 to make it parallel to the wall. S200. Based on the height and height difference parameters of the pre-cast hole, firstly, use the main lifting frame 7 to adjust the detection module 2 3 to align with the highest pre-cast hole. Secondly, loosen the fastening bolts under the two sets of anti-deviation rods 9 installed on the surface of the rotating frame 6. Use the auxiliary lifting frame 8 to adjust the detection module 2 to align with the lowest pre-cast hole. Finally, adjust the height of the fastening bolts according to the base 21. S300, in conjunction with the horizontal movement of the mobile vehicle 1, precisely aligns the detection module 1 2 and the detection module 2 3 with the two sets of precast holes. The horizontal moving frame 4 controls the two sets of anti-deviation rods 9, the detection module 1 2, the detection module 2 3, and the drive module 5 to move toward the precast holes. Finally, the detection module 1 2 and the detection module 2 3 detach from the main lifting frame 7 and the auxiliary lifting frame 8 and enter the precast holes. S400. When the laser sensors integrated at both ends of the base 21 detect that the distributed hydraulic loading module 22 is located in the middle of the pre-made hole, the drive rod 1 51 and the transmission module 23 are used to control the rotating rod 242 and the clamping member 241 to rotate 90 degrees. Then, the drive rod 2 52 and the transmission module 23 are used to control the threaded rod 252 to rotate. The rotating threaded rod 252 controls the two sets of clamping members 241 to adhere to the wall surface through the bidirectional moving member 251. On the one hand, it is used to enhance the stability of the equipment and prevent the detection module 1 2 and the detection module 2 3 from lateral displacement, which reduces the detection accuracy. On the other hand, it can ensure the hole position accuracy of the other two reference holes 212 on the surface of the upper and lower bases 21, so as to facilitate the installation of two other sets of anti-deviation rods 9 from the other side of the wall. S500 uses several sets of miniature hydraulic cylinders in the distributed hydraulic loading module 22 to perform hydraulic loading tests. The pressure and displacement sensors built into each cylinder provide real-time feedback, and the control module adjusts the oil supply pressure of each cylinder to eliminate detection errors caused by eccentricity.

[0041] S600, after the detection is completed, the control of all the above components is reset, and finally the device is stored in the mobile vehicle body 1 with the rotating shaft 61 as the axis. It has the characteristics of ingenious structural fit, prevention of lateral deviation, easy adjustment, automatic detection, high detection accuracy and easy storage.

[0042] In summary, this application can not only automatically and accurately deliver detection module 1 2 and detection module 2 3 into the pre-drilled hole, but also control the clamping parts 241 in detection module 1 2 and detection module 2 3 to horizontally clamp the wall while ensuring that the distributed hydraulic loading module 22 is in the middle position of the pre-drilled hole. This not only solves the problem of reduced detection accuracy due to eccentricity, but also facilitates the installation of the anti-eccentricity rod 9, and has the characteristics of high detection efficiency and high accuracy. This application can not only automatically detect building walls with pre-drilled holes at different tilt angles, but also automatically detect building walls without pre-drilled holes (such as beams, cantilever beams, and other building structures). After detection, it can automatically retract and reduce its volume, and has the characteristics of being easy to adjust, having a wide range of applications, and being suitable for narrow spaces.

These new embodiments can be implemented in various other ways, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution.

Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
