Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering measurement, in particular to a building verticality measuring device. Background Art

[0002] In building structures, walls are one of the main load-bearing components. The verticality of the wall has an important impact on the stability of the building. In order to ensure the overall stability and safety of the building, it is necessary to measure the verticality of the building wall.

[0003] For example, the patent with announcement number CN216593153U discloses a verticality measuring device for building inspection. When working, the support plate is placed vertically on the bonding plate, and the reel is rotated to lower the weight to a certain height. Then the state of the angle plate group is changed to form a semicircular structure, and the bonding plate is attached to the side wall of the building and moved to a certain position. At the same time, the angle of the rope corresponding to the angle plate group is observed to obtain the verticality of the side wall.

[0004] However, this technical method still has the following problems when measuring the verticality of buildings: 1. The side of the building is not completely flat. When the plywood is attached to the uneven side wall of the building, the more convex part of the side of the building will change the angle of the plywood, and this angle is not the true verticality of the side wall of the building. As a result, there is an error in the verticality of the building side indicated by the rope on the angle plate group, which reduces the accuracy of the verticality measurement; 2. When the surveyor moves the equipment, the weight will shake, and the reading must be made after the weight stabilizes. The time required for the weight to stabilize is long, which is not conducive to improving the efficiency of building verticality measurement. Utility Model Content

DETAILED DESCRIPTION

[0022] Example

[0023] See also Figures 1 to 3 The utility model provides a building verticality measuring device, including a plumb bob 1, a hanging line 2, a scale plate 3, a connecting tube 4, a fixing frame 5, an elastic telescopic component 10 and a driving mechanism 11, wherein the elastic telescopic component is fixed to the top of the fixing frame 5, and the elastic telescopic component includes a telescopic rod 26 and a spring 27, the fixed end of the telescopic rod 26 is fixed to the fixing frame 5, the spring 27 is sleeved on the outside of the telescopic rod 26, and the two ends of the spring 27 are respectively connected to the fixing frame 5 and the telescopic end of the telescopic rod 26, the telescopic end of the elastic telescopic component is connected to the hanging line 2, and the free end of the hanging line 2 is connected to the plumb bob 1, the scale plate 3 is connected to the fixing frame 5, and the scale plate 3 is two pieces, which are respectively located on both sides of the hanging line 2, so that readings from both sides are convenient. An electromagnet 15 is installed at the bottom of the fixing frame 5, and the electromagnet 15 cooperates with the plumb bob 1. The elastic telescopic component extends under the action of magnetic force, driving the plumb bob 1 to move down and contact with the electromagnet 15, and the electromagnet 15 magnetically attracts the plumb bob 1. The time that the plumb bob 1 shakes when using this device can be reduced, and the efficiency of measuring the verticality of the building can be improved. The driving mechanism 11 is installed on one side of the fixing frame 5 through the installation box 16, and the connecting tube 4 is fixed on the installation box 16. Two groups of adjusting rods 17 are slidably connected in the connecting tube 4, and the ends of the adjusting rods 17 are connected with the pressure plate 21. The driving mechanism 11 is transmission-connected with the two groups of adjusting rods 17 to adjust the length of the adjusting rods 17. A control button 22 is provided on the fixing frame 5. The electromagnet 15 and the driving mechanism 11 are electrically connected to the corresponding control button 22. The control button 22 electrically connected to the electromagnet 15 can control the on or off of the switch of the electromagnet 15. When the length of the adjusting rod 17 needs to be adjusted, the driving mechanism 11 is started, and the driving mechanism 11 drives the two groups of adjusting rods 17 to move toward or away from each other, thereby driving the pressure plate 21 to move, so that the pressure plate 21 acts on the smoother wall surface of the building, thereby improving the accuracy of the verticality measurement of the building.

[0024] The fixing frame 5 includes a fixing frame 6, a fixing seat 7 and a handle 9. The fixing seat 7 is fixed in the fixing frame 6. A fixing chamber 8 is provided in the fixing seat 7. The fixed end of the elastic telescopic member is fixed in the fixing chamber 8, which is convenient for the installation of the elastic telescopic member. The handle 9 is connected to the side of the fixing frame 6. The surveyor holds the handle 9 and presses the two pressure plates 21 against the building wall.

[0025] See also Figure 1 and Figure 2 The driving mechanism 11 includes a motor 12, a driving gear 13 and two driven gears 14. The output shaft of the motor 12 is connected to the driving gear 13. The two driven gears 14 are connected to the corresponding adjusting rods 17. The driving gear 13 is meshed with the two driven gears 14.

[0026] The adjusting rod 17 includes a screw 18 and a sliding rod 19, one end of the screw 18 is connected to the driven gear 14, wherein one end of the screw 18 is connected to a connecting shaft 20, which is connected to the driven gear 14, and a stabilizing ring 28 is connected in the connecting tube 4. The screw 18 is a threaded part that is rotatably connected to the stabilizing ring 28, and the free end of the screw 18 is threadedly connected in the sliding rod 19, and the sliding rod 19 is slidably connected in the connecting tube 4, and the end of the sliding rod 19 is connected to the pressure plate 21.

[0027] The motor 12 drives the driving gear 13 to rotate, and the driving gear 13 is engaged with the two driven gears 14. One end of the screw 18 is connected to the driven gear 14, thereby driving the screw 18 to rotate. The screw 18 is threadedly connected to the sliding rod 19. The rotation of the screw 18 causes the sliding rod 19 to extend outside the connecting tube 4, thereby driving the pressure plate 21 to move, making it convenient for the pressure plate 21 to move to the relatively smooth wall surface of the corresponding building, effectively reducing the verticality measurement error caused by the bulges on the building plane.

[0028] The pressing plate 21 is connected to the adjusting rod 17 via a connecting rod 23 .

[0029] The installation box 16 is provided with a plurality of heat dissipation holes 24 for heat dissipation. The bottom of the installation box 16 is connected to a damping plate 25 , and the driving mechanism 11 is mounted on the damping plate 25 to reduce vibration of the driving mechanism 11 during operation.

[0030] During operation, the handle 9 is held to bring the pressing plate 21 close to the building wall. According to the smoothness of the pressing plate 21 on the wall, the motor 12 is started, and the adjusting rod 17 slides in the connecting tube 4. The length of the adjusting rod 17 is adjusted to drive the pressing plate 21 to move. The pressing plate 21 avoids the building wall with poor flatness and presses the pressing plate 21 against the relatively flat wall of the building, thereby reducing the error in vertical measurement caused by the uneven building wall. After selecting the pressing plate 21 and the pressing wall of the building, the power is disconnected by the control button 22. The electromagnetic switch of the magnet 15, the magnetic force of the electromagnet 15 on the plumb bob 1, the elastic telescopic rod 26 drives the plumb bob 1 to move upward through the suspension line 2, the plumb bob 1 is separated from the electromagnet 15, and under the action of the gravity of the plumb bob 1, the suspension line 2 indicates the scale on the scale plate 3, and the verticality of the building wall is obtained through the scale plate 3. The plumb bob 1 of the present application is released after the pressure plate 21 is pressed against the building wall, which can reduce the degree of shaking of the plumb bob 1 when holding the device, shorten the time required for the plumb bob 1 to stabilize, improve the efficiency of building verticality measurement, and reduce the workload of the surveyor.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
