Description

Technical Field

[0001] This utility model belongs to the field of shear wall construction technology, specifically relating to a shear wall verticality detection device. Background Technology

[0002] As a core component in buildings resisting horizontal loads (such as wind loads and seismic forces), the verticality of shear walls directly affects the rationality of load transfer paths. Excessive verticality deviation can lead to uneven stress distribution within the wall, weakening its overall seismic performance and even causing safety hazards. Therefore, it is necessary to inspect the verticality of shear walls during construction and promptly rework or rectify any deviations exceeding the allowable range.

[0003] Currently, the plumb bob measurement method is commonly used on construction sites. The upper end of the plumb line is fixed to the top of the shear wall to ensure that the fixing point is stable. After the plumb line comes to rest, the distance between the plumb line and various points on the wall is measured to see if they are consistent. Multiple points are selected along the height of the wall to measure and record the data. The verticality deviation is determined through statistical analysis.

[0004] The plumb bob measurement method described above requires manual measurement of the distance between the plumb line and various points on the wall multiple times. Manual measurement is time-consuming, affecting the detection efficiency, and the measurement accuracy is greatly affected by human factors.

[0005] Therefore, it is necessary to design a shear wall verticality detection device that can quickly measure the distance between the plumb line and various points on the wall surface, thereby improving detection efficiency and reducing the impact of human factors on measurement accuracy, in order to solve the current technical problems.

[0027] like Figures 1 to 6As shown, the shear wall verticality detection device includes a support plate 1. A laser rangefinder 7 is installed on one side of the support plate 1. A linear drive mechanism 6 is installed on the support plate 1 to drive the laser rangefinder 7 to slide along it. Fixed brackets 11 and adjustable brackets 8 are respectively installed at the upper and lower ends of the support plate 1 near the laser rangefinder 7. A top plate 2 and a bottom plate 3 are respectively installed at the upper and lower ends of the support plate 1 away from the laser rangefinder 7. A plumb bob 4 is suspended below the top plate 2 by a plumb line 41. A connection is provided between the top plate 2 and the bottom plate 3, which is connected to one side of the support plate 1. A vertical side plate 5 and a support plate 1 are respectively provided with a first reference line 51 and a second reference line 13 along the vertical direction; the upper ends of the first reference line 51 and the second reference line 13 correspond to the projection position of the suspension point of the plumb line 41; a microcontroller module is connected to the laser rangefinder 7, and a broadcast module is connected to the microcontroller module; the linear drive mechanism 6 is connected to the microcontroller module; in this embodiment, during detection, the fixed bracket 11 and the adjustable bracket 8 are pressed against the wall, the fixed bracket 11 is fixed at a fixed height against the wall, and the plumb bob 4 is stabilized before the reference line is drawn. Adjust the angle of the support plate 1 along the wall according to the plumb line 41. Under a viewing angle where the line of sight is perpendicular to the support plate 1, make the second reference line 13 coincide with the plumb line 41. Then adjust the extension and retraction of the adjustable bracket 8. Under a viewing angle where the line of sight is perpendicular to the side plate 5, make the first reference line 13 coincide with the plumb line 41, completing the adjustment of the support plate 1. At this point, testing can be performed. During testing, the microcontroller module drives the laser range sensor 7 to move sequentially downwards or upwards to a preset position. Then, the microcontroller module obtains the distance between that position and the wall through the laser range sensor 7 and broadcasts the distance via a broadcast module. The device broadcasts voice information while data is manually recorded. The verticality deviation is determined through statistical analysis. In this embodiment, the shear wall verticality detection device can replace manual labor to quickly measure the distance between the vertical line and various points on the wall, improving detection efficiency and reducing the impact of human factors on measurement accuracy. Furthermore, the broadcast module can broadcast the distance values ​​obtained by the laser rangefinder 7 at different points, facilitating recording by the inspection personnel. More specifically, the linear drive mechanism 6 can drive the laser rangefinder 7 to move 10cm each time to perform a measurement.

[0028] In the above embodiments, the microcontroller module, broadcasting module, linear drive mechanism 6 and laser rangefinder sensor 7 in the shear wall verticality detection device are powered by an integrated battery. The specific power supply method is based on existing technology and will not be described in detail here.

[0029] In some embodiments, a groove 12 is provided on the side of the support plate 1 near the laser rangefinder 7. The linear drive mechanism 6 has a movable block 63 slidably disposed inside the groove 12. A lead screw 61 is threadedly connected to the inside of the movable block 63. A drive motor 64 for driving the lead screw 61 to rotate is fixedly disposed at the top of the support plate 1. A motor driver is connected to the drive motor 64 and the motor driver is connected to a microcontroller module. The laser rangefinder 7 is disposed on one side of the movable block 63. The drive motor 64 drives the lead screw 61 to rotate, and the threaded structure between the lead screw 61 and the movable block 63 drives the movable block 63 to move. The movable block 63 drives the laser rangefinder 7 to move up and down to different points to complete the distance measurement. The drive motor 64 can be a servo motor or a stepper motor. Servo motors and stepper motors have high position control accuracy and can control the moving position of the movable block 63 more accurately.

[0030] In some embodiments, two guide rods 62 parallel to the lead screw 61 are symmetrically fixedly arranged inside the slide groove 12. The moving block 63 is slidably connected to the guide rods 62 and cooperates with the guide rods 62, and is slidably arranged inside the slide groove 12.

[0031] In some embodiments, the adjustable bracket 8 has a lower support 81 fixedly disposed at the bottom end of the support plate 1. A sliding plate 82 is slidably disposed inside one end of the lower support 81. A sliding cavity matching the sliding plate 82 is opened inside one end of the lower support 81. The sliding plate 82 is slidably disposed inside the sliding cavity. An adjusting bolt 85 is rotatably disposed inside the other end of the lower support 83. The adjusting bolt 85 is threadedly connected to the sliding plate 82. A lower support plate 84 is fixedly disposed at the end of the sliding plate 82. A lower anti-slip strip 84 is fixedly disposed on one side of the lower support plate 83. By rotating the adjusting bolt 85, the threaded structure between the adjusting bolt 85 and the sliding plate 82 drives the sliding plate 82 to extend and retract at the end of the lower support 81, thereby adjusting the length of the adjustable bracket 8. When the length of the adjustable bracket 8 is adjusted, it will push the lower end of the support plate 1 to move, thereby adjusting the first reference line 51 to correspond with the vertical line 41, so that the support plate 1 is adjusted to a vertical state to ensure the accuracy of subsequent detection.

[0032] In some embodiments, the fixed bracket 11 has a fixed support plate 111 vertically fixedly disposed on the upper end of the support plate 1, and an upper anti-slip strip 112 is fixedly disposed at the end of the fixed support plate 111.

[0033] In some embodiments, a lower support edge 31 is fixedly provided on the top outer side of the base plate 3, and a plumb lock mechanism 9 for locking or releasing the plumb 4 is provided on the lower support edge 31 and the support plate 1; when moving the shear wall verticality detection device, locking the plumb 4 by the plumb lock mechanism 9 can prevent the plumb 4 from shaking and reduce safety hazards.

[0034] In some embodiments, the plumb lock mechanism 9 has a clamping seat 91 fixedly mounted on the support plate 1 corresponding to the plumb 4, and a clamping screw 93 threadedly connected to the lower support edge 31. The end of the clamping screw 93 is rotatably mounted with a clamping plate 92 corresponding to the plumb 4.

[0035] In some embodiments, the plumb bob 4 is provided with an annular groove 42 corresponding to the clamping seat 91 and the clamping plate 92. When the plumb bob 4 is clamped and locked, the clamping seat 91 and the clamping plate 92 are just embedded in the annular groove 42 to ensure the stability of clamping the plumb bob 4.

[0036] In some embodiments, an arc-shaped baffle 51 is fixedly provided between the side plate 5 and the support plate 1.
