Description

Technical Field

[0001] This utility model relates to the field of shear wall calibration technology, and in particular to a calibration device for shear wall construction. Background Technology

[0002] In the construction of shear walls in building engineering, verticality calibration is a key link to ensure that the quality of shear walls meets the standards. Its accuracy is directly related to the structural safety and stability of the building, and the height adjustment function plays a vital role in the shear wall verticality calibration device. Traditional methods for calibrating the verticality of shear walls often lack an effective and flexible height adjustment mechanism. In the past, when using a plumb line and steel ruler to measure verticality, the plumb line was suspended at a relatively fixed height. To measure the verticality of the shear wall at different heights, construction workers needed to repeatedly climb with the aid of ladders and other auxiliary tools to change the starting point of the measurement. This increased the labor intensity of the construction workers and significantly increased the safety risks during the construction process, as frequent climbing operations could easily lead to accidents such as falls. As the construction industry develops towards higher-rise, larger-scale, and more complex structures, higher demands are placed on the accuracy and efficiency of shear wall verticality calibration. Existing calibration methods lacking height adjustment capabilities are no longer adequate for the needs of modern construction. Therefore, it is urgent to develop a calibration device for shear wall construction with efficient and flexible height adjustment capabilities, so that construction workers can perform verticality calibration at different heights, thereby improving construction quality and efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] A calibration device for shear wall construction, such as Figures 1 to 5 As shown, the bracket includes a support 1. A winding assembly is installed on the inner walls of both sides of the support 1, and a traction rope 7 is wound on the winding assembly. A traction cone 6 is fixed to the bottom of the traction rope 7. A telescopic plate is installed on the outer wall of one side of the support 1. A connecting rod 16 is fixed to one side of the telescopic plate. An installation plate 5 is welded to one end of the connecting rod 16. A support plate is installed at the bottom of the installation plate 5. A scale strip 20 that cooperates with the traction cone 6 is adhered to the surface of the installation plate 5.

[0024] When the verticality of the shear wall needs to be checked, first place the support plate on a horizontal surface and adjust the length of the telescopic plate. Once the length of the telescopic plate is adjusted to the appropriate length, use the winding assembly to unwind the traction rope 7. During the unwinding process, the traction rope 7 drives the traction cone 6 to move towards the scale strip 20 on the mounting plate 5. The traction cone 6 has a conical structure. When the tip of the traction cone 6 moves to a distance of 1-2 mm from the scale strip 20, the winding assembly stops unwinding the traction rope 7. When the traction cone 6 is stationary, its vertical position can be visually checked. Observe the scale value on the surface of the scale bar 20 pointing upwards. The observed scale value is set as the initial value. Then, place the back of the telescopic plate against the surface of the shear wall. The back of the telescopic plate is a flat plane. After the telescopic plate is against the surface of the shear wall, wait for the traction cone 6 to come to a stop. After the traction cone 6 comes to a stop, the scale value on the surface of the scale bar 20 pointing vertically is the measured value. By comparing the measured value with the initial value, if the two are the same or the error is within the allowable range, it proves that the verticality of the shear wall is not a problem and the calibration is qualified. If the error between the measured value and the initial value is greater than the allowable range, the verticality calibration of the shear wall is not up to standard.

[0025] The winding assembly includes a winding disc 9, a worm gear 10, and a rotating shaft 11. The rotating shaft 11 is rotatably connected to the inner wall of the through holes on both sides of the bracket 1. The winding disc 9 and the worm gear 10 are both fixed to the outer circumference of the rotating shaft 11. The traction rope 7 is wound around the outer circumference of the winding disc 9. A top plate 27 is welded to the inner wall of one side of the bracket 1. A worm 25 is rotatably connected to the bottom of the top plate 27. A handle 26 is fixed to the bottom of the worm 25. The worm gear 10 and the worm 25 mesh with each other.

[0026] The worm gear mechanism consisting of worm 25 and handle 26 has the functions of speed reduction, torque increase and self-locking. In this embodiment, its function is to achieve self-locking. That is, when the worm 25 is rotated by holding the handle 26, the worm 25 drives the winding disc 9 and worm wheel 10 to rotate. The rotation of the winding disc 9 realizes the winding and unwinding of the traction rope 7. Since the worm 25 and handle 26 can achieve self-locking, when the traction cone 6 moves to the set position, the traction cone 6 can be kept at rest to ensure stability and prevent it from falling.

[0027] The telescopic plate includes a calibration plate 1 2 and a calibration plate 2 4. A guide plate 3 is welded to the top of the calibration plate 2 4, and the guide plate 3 and the calibration plate 1 2 are slidably connected. The connecting rod 16 is welded and fixed to the calibration plate 2 4. An extension plate 2 23 and an extension plate 1 22 are respectively welded to the inner wall of one side of the calibration plate 1 2 and the inner wall of one side of the calibration plate 2 4. A threaded rod 24 is threadedly connected to the surface of the extension plate 1 22. The top of the threaded rod 24 and the bottom of the extension plate 2 23 are rotatably connected. A handle 1 21 is fixed to the bottom of the threaded rod 24.

[0028] When it is necessary to adjust the straight distance between the top of the calibration plate 1 2 and the bottom of the calibration plate 2 4, the threaded rod 24 is rotated by holding the handle 1 21. The bracket 1 and the calibration plate 2 4 move relative to each other under the guidance of the guide plate 3. The back of the calibration plate 1 2 and the back of the calibration plate 2 4 are both flat. When it is necessary to calibrate the shear wall, the back of the calibration plate 1 2 and the back of the calibration plate 2 4 are attached to the surface of the shear wall to achieve the verticality calibration of the shear wall.

[0029] A guide frame 15 is welded to one side of the outer wall of the calibration plate 12, and a guide wheel 14 for guiding the traction rope 7 is rotatably connected to the inner wall of the guide frame 15.

[0030] By providing guide wheels 14, the traction rope 7 can be guided during winding or unwinding. The traction cone 6 itself has a certain weight, thereby ensuring the smooth movement of the traction rope 7 during winding or unwinding.

[0031] The guide frame 15 has the same handle 8 welded to the outer walls on both sides, and the outer wall of the handle 8 is wrapped with an anti-slip ring 13.

[0032] When it is necessary to place the telescopic plate against the shear wall surface, the anti-slip ring 13 can be used to hold the anti-slip ring 13 for easy operation. The anti-slip ring 13 can improve the anti-slip ability and prevent slippage during the hand grip.

[0033] The support plate includes a support base 12 and a column 18. The column 18 is welded to the top outer wall of the support base 12. A threaded column 17 is welded to the top of the column 18, and a threaded groove 19 adapted to the threaded column 17 is opened at the bottom of the mounting plate 5.

[0034] By connecting the threaded column 17 and the threaded groove 19 with threads, the support base 12 and the mounting plate 5 can be fixed. The support base 12 supports the entire device. At the same time, the threaded column 17 and the threaded groove 19 allow the support base 12, the column 18 and the mounting plate 5 to be disassembled. When it is necessary to calibrate the verticality of the shear wall, the threaded column 17 and the column 18 can be removed to reduce the weight of the entire device and facilitate better operation.

[0035] Working principle: First, screw the threaded post 17 of the support base 12 into the threaded groove 19 at the bottom of the mounting plate 5 to fix it, thus supporting the entire device. Hold the handle 21 to drive the threaded rod 24 to rotate, causing the calibration plate 2 and calibration plate 4 to move relative to each other under the guidance of the guide plate 3, thereby adjusting the telescopic plate to the appropriate length. Then, hold the handle 26 to rotate the worm gear 25, which drives the winding disc 9 to unwind the traction rope 7 through the worm gear transmission, allowing the traction cone 6 to gradually approach the scale bar 20. When the distance between the cone tip and the scale bar 20 is 1-2mm, stop unwinding. At this time, observe and record the scale value as the initial value. Then, press the back of the telescopic plate tightly against the shear wall surface. After the traction cone 6 comes to a stop, observe and record the scale value pointing to the scale bar 20 as the measured value. Finally, compare the initial value and the measured value. If the two are the same or the error is within the allowable range, the verticality of the shear wall is qualified; otherwise, it is not qualified.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
