Description

Technical Field

[0001] The present application relates to the field of building keel detection, and in particular to a building keel bearing capacity detection device and detection method. Background Art

[0002] In the construction industry, keels are a building material used to support shapes and secure structures. They serve as the framework and base material for decoration and are widely used. There are many types of keels, and depending on the material used, they can be divided into wooden keels, light steel keels, aluminum alloy keels, and steel keels. Based on where they are used, they can be further divided into ceiling keels, partition keels, floor keels, and suspension keels.

[0003] Partition wall studs generally play a supporting role within the wall, so before the studs are put into actual use, they are generally subject to load-bearing capacity testing. During operation, the studs are installed between two panels to simulate the wall structure, supporting the end walls of the wall structure so that the middle of the wall structure is suspended in the air. The wall structure is then loaded, and after a period of time, the deformation of the wall structure is observed.

[0004] For most load-bearing capacity testing work, the common loading method is to manually place a vertical weight of corresponding weight on the structure to be tested. However, the vertical weight has a certain weight, and manual movement is time-consuming and labor-intensive. Summary of the Invention

[0005] In order to conveniently place vertical weights on the structure to be inspected to achieve loading, the present application provides a building keel bearing capacity detection device and detection method.

[0006] In a first aspect, the present application provides a device for detecting the bearing capacity of building keels, which adopts the following technical solution:

[0007] A device for detecting the bearing capacity of a building keel comprises a frame, a bearing mechanism mounted on the frame, and a loading mechanism mounted on the frame, the loading mechanism comprising a lifting guide rod, a vertical weight block, and a limit support plate, the lifting guide rod being arranged on the frame, a plurality of vertical weight blocks being slidably arranged on the lifting guide rod in sequence along the vertical direction, and the vertical weight block and the lifting guide rod sliding freely; a mounting rod is provided on the frame, the limit support plate is connected to the mounting rod and is arranged corresponding to the vertical weight block, the limit support plate is fitted with the bottom wall corresponding to the vertical weight block, a driving component for driving the limit support plate to move is provided on the mounting rod, and a supporting component for supporting the vertical weight block is also provided at the bottom end of the lifting guide rod.

[0008] By adopting the above technical solution, the limiting support plate supports the vertical weight block, and the lifting guide rod guides the vertical weight block, so that the vertical weight block can be stably located in the specified position; when loading is required, the driving assembly can be operated to make the limiting support plate lose the limit on the vertical weight block. At this time, the lifting guide rod guides the vertical weight block, so that the supporting assembly can stably receive the vertical weight block and transfer the gravity to the structure to be inspected. Therefore, this application can place the vertical weight on the structure to be inspected more conveniently and labor-savingly to achieve loading.

[0009] Optionally, the position where the limiting support plate and the vertical weight block are fitted is a fan-shaped plate, and the central angles of several fan-shaped plate parts of the limiting support plate from top to bottom become smaller successively. The driving assembly includes a rotating seat, and the rotating seat rotates on the frame, and the mounting rod is fixedly connected to the rotating seat.

[0010] By adopting the above technical solution, since the central angles of the fan-shaped parts of the limit support plate are different, after the mounting rod is rotated to a certain angle, only the limit support plate with a smaller central angle will move away from the vertical weight block, and the limit support plate with a larger central angle moves to support the vertical weight block above it. Therefore, the vertical weight blocks can be released one by one as needed, which is convenient and quick.

[0011] Optionally, the supporting assembly includes a pull rope and a supporting rod arranged at the bottom end of the pull rope, the top end of the pull rope is arranged on the lifting guide rod through a retractable assembly, the supporting rod is fixedly installed at the bottom end of the pull rope, and a clearance groove is provided at the bottom end of the lifting guide rod, the clearance groove passes through the lifting guide rod in a horizontal direction, and the supporting rod and the clearance groove are opposite to each other.

[0012] By adopting the above technical solution, the vertical weight block slides down along the lifting guide rod and can naturally fall on the supporting rod. By adjusting the length of the pull rope so that the pull rope is not under stress, the weight of the vertical weight block can be transferred to the structure to be inspected.

[0013] Optionally, the retracting and releasing assembly includes a retracting and releasing wheel, a mounting seat is provided at the top end of the lifting guide rod, a driving member is provided on the mounting seat, the retracting and releasing wheel is rotatably connected to the mounting seat and connected to the driving member, the end of the pull rope away from the supporting rod is fixedly connected to the retracting and releasing wheel, the bottom wall and the top wall of the vertical weight block are provided with guide angles at both ends along the rotation circumference of the mounting rod, the top wall and the bottom wall of the limiting support plate are provided with guide angles at both ends along the rotation circumference of the mounting rod, and a positioning sensing member for controlling the operation of the driving member is provided on the vertical weight block.

[0014] By adopting the above technical solution, the retractable wheel rotates, the pull rope is released from the retractable wheel, and the vertical weight block can be gradually placed on the structure to be inspected through the supporting rod; at the same time, the setting of the yield groove enables the supporting rod to drive the vertical weight block to move up to the original position. During this process, the positioning sensor can automatically pause the rotation of the mounting rod when the vertical weight block returns to the original position; at this time, the mounting rod is rotated, and the guide angle of the limiting support plate can be inserted under the vertical weight block along the guide angle of the vertical weight block, fully supporting the vertical weight block, which is convenient and quick.

[0015] Optionally, the positioning sensing component includes a buffer spring and a force block, the buffer spring is fixedly connected to the top of the vertical weight block, the force block is arranged at the top of the buffer spring, and a pressure sensor for controlling the operation of the driving component is arranged at the top of the force block. A positioning support plate is provided on the mounting seat, and the positioning support plate is located above all the vertical weight blocks. The pressure sensor is opposite to the vertical weight block or positioning support plate adjacent to it.

[0016] By adopting this technical solution, as the vertical weight moves upward, the force-bearing block contacts the object above, causing the buffer spring to move and compress, creating space for the vertical weight to move. When the vertical weight returns to its original position, the pressure sensor controls the actuator based on the detected pressure. The buffer spring provides a buffer for the vertical weight and, when the limit plate is reinserted into the bottom of the vertical weight, it moves a certain distance above the vertical weight. During this process, the buffer spring ensures the required displacement of the vertical weight.

[0018] By adopting the above technical solution, the support plate can support large structures to be inspected, and large keels can be built into wall structures for testing. For small keels, the keel is hooked with a clamping block and suspended between two support beams. A plate is then placed above the keel and loaded to test the load-bearing capacity of the small keel.

[0020] By adopting the above technical solution, the feed screw and the drive seat are threadedly fed, which can drive the drive seat to slide, thereby adjusting the position of the mounting rod and the lifting guide rod, and then adjusting the position of the vertical weight block, so that the vertical weight block can be loaded according to the appropriate position of the structure to be inspected.

[0021] In a second aspect, the present application provides a method for detecting the bearing capacity of building keels, which adopts the following technical solution:

[0022] A detection method using the above-mentioned building keel bearing capacity detection device includes the following steps:

[0023] Operate the load-bearing assembly to install the structure to be inspected on the frame so that the structure to be inspected is suspended in the air;

[0024] According to the required loading weight, rotate the mounting rod and drop the corresponding number of vertical weight blocks onto the structure to be inspected to complete the loading work; finally, observe the deformation of the structure to be inspected.

[0027] 2. The limit support plate of the present application also includes a fan-shaped part, so that the limit support plate is driven to rotate by the rotation of the mounting rod. Since the central angles of the fan-shaped plate parts of several limit support plates from top to bottom become smaller in sequence, the limit support plates can leave the corresponding vertical weight blocks in sequence, so that the loading work can be completed according to the corresponding number of vertical weight blocks below as needed.

In this embodiment, the top and bottom walls of the support beam 28 are integrally connected to limit plates 224. The limit plates 224 extend horizontally and perpendicular to the support beam 28. The clamping plate 221 abuts against the top wall of the support beam 28, positioning the flexible clamping block 223 on the side of the support beam 28 away from the connecting plate 222. The flexible clamping block 223 is then bent so that the end of the flexible clamping block 223 away from the connecting plate 222 extends below the limit plate 224. The clamping plate 221 is then fixed to the support beam 28.

[0040] For large keels, secure the keel between two wooden or gypsum boards to create a sample, simulating a wall structure. The sample is then placed on a support plate 21, with the support plate 21 supporting the sample's sidewalls at their edges.

For small keels, insert the clamping block 225 from the keel's open end, so that the clamping block 225 abuts the keel's inner sidewall. Two keels are installed between two support beams 28, and a load-bearing plate is placed on top of the two keels. The loading mechanism 3 is then operated to apply a load to the middle portion of the load-bearing plate, and the deformation of the keels is observed.

[0041] like Figure 3 and Figure 4As described above, the loading mechanism 3 in this embodiment includes a lifting guide rod 31, a vertical weight block 32, and a limit support plate 33. A sliding seat 34 is slidably provided on one side wall of the mounting frame 11 via a moving assembly 4. The sliding direction of the sliding seat 34 is parallel to the relative direction of the two mounting frames 23. The moving assembly 4 includes a feed screw 41, which is rotatably connected to the mounting frame 11. The mounting frame 11 is equipped with a drive device 42. The drive device 42 is a motor with a drive end fixedly connected to one end wall of the feed screw 41. The sliding seat 34 and the feed screw 41 are slidably connected.

[0042] like Figure 3 、 Figure 4 and Figure 5 As shown, the sliding seat 34 is fixedly connected to a support frame 35. There are two lifting guide rods 31, each with its top end fixedly connected to the top of the support frame 35. The two lifting guide rods 31 are located above the middle portion of the mounting frame 11. In this embodiment, there are three vertical weights 32, each of which has two guide slots 321 extending vertically therethrough. The vertical weights 32 are mounted on the two lifting guide rods 31 through the guide slots 321, allowing for free sliding movement between the vertical weights 32 and the lifting guide rods 31. A mounting rod 36 is also rotatably connected to the top wall of the sliding seat 34 via a drive assembly 5. The drive assembly 5 includes a rotating seat 51 rotatably connected to the top wall of the sliding seat 34. The bottom end of the mounting rod 36 is fixedly connected to the top wall of the rotating seat 51.

[0043] like Figure 4 、 Figure 5 and Figure 6 As shown, the limiting plates 33 are fixedly connected to the mounting rods 36 and are arranged one-to-one with the vertical weights 32. The limiting plates 33 are fan-shaped plates, with the top limiting plate 33 having a central angle of 90°, the middle limiting plate 33 having a central angle of 60°, and the bottom limiting plate 33 having a central angle of 30°. The two limiting plates 33 have equal diameters. The top walls of the limiting plates 33 are rotatably provided with drag-reducing rollers 37, which engage the bottom walls of the corresponding vertical weights 32. In this embodiment, the bottom end of the lifting guide rod 31 is also provided with a support assembly 6 for supporting the vertical weights 32.

[0044] like Figure 6 As shown, the supporting assembly 6 in this embodiment includes a pull rope 61 and a supporting rod 62 fixedly connected to the bottom end of the pull rope 61, the top end of the lifting guide rod 31 is fixedly connected to the mounting seat 63, the top end of the pull rope 61 is set on the mounting seat 63 through the retracting assembly 7, and the bottom end of the lifting guide rod 31 is provided with a clearance groove 64, the clearance groove 64 extends upward and passes through the lifting guide rod 31 in the horizontal direction, the supporting rod 62 is located in the clearance groove 64, the pull rope 61 is passed through the clearance groove 64 and the top end passes through the lifting guide rod 31 and the mounting seat 63 and is connected to the retracting assembly 7.

[0045] Start the driving device 42, the feed screw 41 rotates, and the sliding seat 34 mobilizes the mounting rod 36 and the lifting guide rod 31 to move to the appropriate position, and then rotate the mounting rod 36 as needed. If the weight of two vertical weights 32 is required, the mounting rod 36 is rotated 60° so that the bottom and middle limit support plates 33 are away from the corresponding vertical weights 32, but the top limit support plate 33 still supports the corresponding vertical weights 32; at this time, the two unsupported vertical weights 32 slide down along the lifting guide rod 31 to the supporting rod 62, and then operate the retracting assembly 7 so that the supporting rod 62 falls on the object to be inspected, and the pull rope 61 is not under force, and the loading is completed.

[0046] like Figure 6 and Figure 7 As shown, the retracting and unretracting assembly 7 in this embodiment includes a retracting and unretracting wheel 71, which is rotatably connected to the mounting seat 63, and a driving member 72 is fixedly connected to the mounting seat 63, and the driving member 72 is a motor; the ends of the two pull ropes 61 away from the supporting rod 62 are fixedly connected to the retracting and unretracting wheel 71; at the same time, in this embodiment, a positioning sensing member 8 is also installed on the vertical weight block 32, and the positioning sensing member 8 includes a buffer spring 81 and a force block 82, the buffer spring 81 is fixedly connected to the top of the vertical weight block 32, the force block 82 is fixedly connected to the top of the buffer spring 81, and a pressure sensor 83 is fixedly installed on the top of the force block 82, and the pressure sensor 83 can control the operation of the driving member 72. At the same time, a positioning support plate 84 is fixedly connected to the mounting seat 63, and the positioning support plate 84 is located above the three vertical weight blocks 32, the pressure sensors 83 on the two lower vertical weight blocks 32 are opposite to the upper adjacent vertical weight blocks 32, and the pressure sensor 83 on the uppermost vertical weight block 32 is opposite to the positioning support plate 84. Moreover, in this embodiment, the bottom wall and the top wall of the vertical weight block 32 are provided with guide bevels 85 at both ends along the rotation circumference of the mounting rod 36, and the top wall and the bottom wall of the limiting support plate 33 are provided with guide bevels 86 at both ends in the circumferential direction.

[0047] The driver 72 is activated, and the retractable wheel 71 rotates, releasing the pull rope 61 from the retractable wheel 71, thereby lowering the support rod 62. During this process, the pressure sensor 83 does not operate. After the test is completed, the driver 72 is activated, and the retractable wheel 71 rotates and receives the pull rope 61 from the retractable wheel 71. The support rod 62 drives the vertical weight 32 upward, and the pressure sensor 83 located above the support rod 62 operates. When the vertical weight 32 moves to the specified position, the operating pressure sensor 83 is abutted by an object above. At this time, the pressure sensor 83 senses that the pressure has reached the specified value, and the driver 72 is suspended. At this time, the mounting rod 36 is rotated to insert the corresponding guide bevel 86 on the limit support plate 33 into the band bevel of the vertical weight 32, so that the limit support plate 33 can be inserted into the bottom end of the corresponding vertical weight 32 to support the vertical weight 32, and the vertical weight 32 returns to its original position.

[0048] The present invention also provides a method for testing the bearing capacity of building keels. Using the testing device in the present invention, a large keel is tested as an example. The required loading weight is equal to the weight of two vertical weight blocks 32. The method specifically includes the following steps:

[0049] The keel is fixed between two gypsum boards by gluing or other means to form a sample simulating the wall structure.

[0050] Place the sample on the support plate 21 so that the sample's end wall rests on the support plate 21. Rotate the mounting rod 36 60°, moving the two lower limit support plates 33 away from their corresponding vertical weights 32. This allows the two lower vertical weights 32 to fall along the lifting guide rod 31 onto the support rod 62. Then, activate the driver 72, causing the support rod 62 to fall onto the sample surface, freeing the pull rope 61 from stress, thus completing the loading process. After a period of time, observe the sample's deformation to complete the test.

[0051] After the detection is completed, the driving member 72 is started, and the supporting rod 62 drives the vertical weight block 32 to move upward until the pressure sensor 83 of the vertical weight block 32 located above suspends the operation of the driving member 72. At this time, the two vertical weight blocks 32 are within the range of the original position, and then the mounting rod 36 is reversed and rotated by 60° so that the limiting support plate 33 supports the corresponding vertical weight block 32 in turn.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
