Description

Technical Field

[0001] This invention belongs to the field of measuring device technology, and particularly relates to a device and method for measuring the tilt angle of buildings. Background Technology

[0002] With the rapid development of the construction industry, in some building structures, especially larger building structures or landmark building projects, in order to increase the aesthetic appeal of the building, architects often break away from the traditional design concept of vertical walls and enhance the building's appearance by setting the exterior walls in a slanted, protruding, recessed, or curved design.

[0003] For building exterior walls with a sloping design, it is often necessary to conduct inspections to determine the quality of the construction during the construction process. If errors occur during the measurement process, there will be a problem of error accumulation in subsequent construction, which may ultimately affect the construction quality of the entire building.

[0004] In the prior art, for example, the patent with the publication number CN216308975U and the name of a building tilt observation device, the device needs to be fixed to the column base of the building to be observed. When the building tilts, the gravity needle rotates due to its own weight. The tilt angle is automatically read by the angle sensor in the gravity needle. Two observation devices need to be set up in the X and Y directions at the same time. Since they need to be fixed to the column base of the building, the measurement angle is limited, resulting in inaccurate measurement results. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a building tilt angle measuring device to solve the technical problem that existing observation devices are prone to installation limitations that affect the accuracy of the measured angle. In addition, this invention also provides a method for measuring building tilt angle.

[0006] To achieve the above objectives, the technical solution adopted by the building tilt angle measuring device of the present invention is as follows: The building tilt angle measuring device includes: Support plate: Used for vertical fixation on the inclined surface of the building to be measured. Reflector: Fixed to the lower surface of the support plate, with an origin point set on the reflector; Measuring ruler: includes a support base, a telescopic rod vertically fixed on the support base, and an arc-shaped ruler plate fixed to the top of the telescopic rod. The arc-shaped ruler plate is set with graduations, and the 0° graduation line of the arc-shaped ruler plate is set to correspond to the axis of the telescopic rod. Laser emitter: fixed on the support base of the measuring ruler. The measuring ruler is provided with a laser path that extends in the vertical direction for the laser to pass through. The axis of the laser path coincides with the axis of the telescopic rod. The axis of the laser path is set to correspond to the origin of the reflector; Adjust the height of the measuring ruler so that the center of the curved plate coincides with the origin of the reflector; The laser emitter emits a laser upwards, which passes through the laser path and illuminates the origin of the reflector to form an incident laser. After being reflected on the reflector, it forms a reflected laser. The reflected laser passes through the arc-shaped ruler of the measuring scale, and the angle between the incident laser and the reflected laser is twice the building's tilt angle.

[0007] Beneficial effects: When using the building tilt angle measuring device, it is only necessary to fix the reflector with a support plate to the tilted surface of the building to be measured. Then, measure the height H of the reflector's origin from the ground. Next, adjust the position of the measuring ruler on the ground according to the position of the plumb bob, so that the measuring ruler is located on the projection of the reflector's origin on the ground. Adjust the height of the measuring ruler to be equal to the difference between the height distance H from the ground to the reflector's origin and the radius R of the curved ruler plate, so that the center of the curved ruler plate is perpendicular to the reflector's origin. Turn on the laser emitter, allowing the laser to pass through the laser path and illuminate the reflector's origin, forming an incident laser. After reflection by the reflector, a reflected laser is formed. The reflected laser passes through the gap between the first and second plates of the curved ruler plate, and the angle corresponding to the reflected laser on the curved ruler plate is twice the building's tilt angle. In this way, the measuring device is not limited by the building structure, making the measurement more convenient and accurate.

[0008] Furthermore, a fixing plate is fixed to the inclined surface of the building to be tested, and the support plate is vertically fixed to the fixing plate.

[0009] Beneficial effect: The fixed plate facilitates the fixation of the support plate.

[0010] The reflector is a circular plate, and the origin is the center of the circular plate.

[0011] Beneficial effect: Reflectors are easy to manufacture.

[0012] The telescopic rod is an electric telescopic rod with a cylindrical cavity in the middle. The axis of the cylindrical cavity coincides with the axis of the electric telescopic rod. The arc-shaped ruler plate has a through hole corresponding to the cylindrical cavity, and the cylindrical cavity and the through hole form a laser path.

[0013] Beneficial effect: The laser path setting facilitates the laser to pass through the measuring ruler and reach the origin of the reflector.

[0014] Furthermore, the laser emitter is fixed on the support base and located at the bottom of the cylindrical cavity.

[0015] Beneficial effect: The laser emitter is fixed more stably.

[0016] Furthermore, the arc-shaped ruler plate includes a first plate and a second plate plate arranged at intervals. A connecting rod is fixed between the first plate and the second plate plate. A cylindrical sleeve is fixed between the first plate and the second plate plate. The inner hole of the cylindrical sleeve is a through hole. The axis of the cylindrical sleeve is arranged in a corresponding manner to the 0° graduation line of the arc-shaped ruler plate.

[0017] Beneficial effect: The gap between the first and second plates of the curved plate allows the laser to pass through easily.

[0018] The method for measuring the tilt angle of a building includes the following steps: S1: Fix the fixing plate to the inclined surface of the building to be measured; S2: Fix the plumb bob at the origin of the reflector, and let the plumb bob hang down naturally. S3: Use a laser rangefinder to measure the height distance H from the ground to the origin of the reflector; S4: Adjust the height of the measuring ruler to be equal to the difference between the height distance H from the ground to the origin of the reflector and the radius R of the curved ruler. S5: Adjust the position of the measuring ruler so that the axis of the laser path corresponds to the origin of the reflector; S6: Turn on the laser emitter so that the laser passes through the laser path and shines on the origin of the reflector to form an incident laser. After being reflected by the reflector, it forms a reflected laser. The reflected laser passes through the gap between the first and second plates of the curved ruler. The angle of the reflected laser on the curved ruler is twice the building's tilt angle.

[0019] Beneficial effects: When using the building tilt angle measuring device, it is only necessary to fix the reflector with a support plate to the tilted surface of the building to be measured. Then, measure the height H of the reflector's origin from the ground. Next, adjust the position of the measuring ruler on the ground according to the position of the plumb bob, so that the measuring ruler is located on the projection of the reflector's origin on the ground. Adjust the height of the measuring ruler to be equal to the difference between the height distance H from the ground to the reflector's origin and the radius R of the curved ruler plate, so that the center of the curved ruler plate is perpendicular to the reflector's origin. Turn on the laser emitter, allowing the laser to pass through the laser path and illuminate the reflector's origin, forming an incident laser. After reflection by the reflector, a reflected laser is formed. The reflected laser passes through the gap between the first and second plates of the curved ruler plate, and the angle corresponding to the reflected laser on the curved ruler plate is twice the building's tilt angle. In this way, the measuring device is not limited by the building structure, making the measurement more convenient and accurate. Attached Figure Description

Detailed Implementation

[0022] The building tilt angle measuring device and its measuring method of the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figure 1 As shown, the building tilt angle measuring device of the present invention includes a support plate 3 vertically fixed to the tilt surface of the building to be measured. To facilitate the fixing of the support plate 3, in this invention, the support plate 3 is vertically fixed to a fixing plate 2, and the fixing plate 2 and the support plate 3 are arranged in a T-shape. The fixing plate 2 is a rectangular plate, and through holes are provided at the four corners of the rectangular plate. Expansion screws pass through the through holes and are fixedly connected to the tilt surface of the building to be measured. At this time, the support plate 3 is perpendicular to the tilt surface of the building to be measured, and the projection of the support plate 3 on the vertical plane (i.e., the paper plane) perpendicular to the front-back direction is a straight line. That is, the support plate 3 will not have a situation where the front end is higher than the back end or vice versa. In this application, the direction perpendicular to the paper plane is defined as the front-back direction.

[0023] A reflector 4 is fixed to the lower surface of the support plate 3. An origin 13 is set on the reflector 4. In this embodiment, the reflector 4 is a circular plate, and the origin 13 is the center of the circular plate. A plumb bob is suspended from the origin 13 of the reflector 4.

[0024] The measuring device also includes a measuring ruler, which comprises a support base 5, a telescopic rod 6 vertically fixed to the support base 5, and an arc-shaped ruler plate 7 fixed to the top of the telescopic rod 6. In this embodiment, the support base 5 is placed on the ground, and the arc-shaped ruler plate 7 is a segment of an arc with a radius of R. The arc-shaped ruler plate 7 is provided with graduations, and the 0° graduation line of the arc-shaped ruler plate 7 is set corresponding to the axis of the telescopic rod 6. The arc-shaped ruler plate 7 is symmetrically arranged about the 0° graduation line. The measuring ruler is provided with a laser path 12 extending in the vertical direction for the laser to pass through. In this embodiment, the telescopic rod 6 is an electrically operated telescopic rod, and a cylindrical cavity is provided in the middle of the electrically operated telescopic rod 6. The axis of the cylindrical cavity coincides with the axis of the electrically operated telescopic rod 6. A through hole corresponding to the cylindrical cavity is opened on the arc-shaped ruler plate 7. The cylindrical cavity and the through hole form the laser path 12, and the axis of the laser path 12 coincides with the axis of the telescopic rod 6. The axis of the laser path 12 is set to correspond to the origin 13 of the reflector 4, that is, the axis of the laser path 12 extends upward through the origin 13 of the reflector 4.

[0025] A laser emitter 8 is fixed on the support base 5 of the measuring ruler. The laser emitter 8 is fixed to the bottom of the cylindrical cavity of the electric telescopic rod 6. The laser emitter 8 can emit laser light that extends in the vertical direction, and the laser light extends upward along the laser path 12 until it reaches the origin 13 of the reflector 4. In this embodiment, the laser light is visible light.

[0026] The arc-shaped ruler 7 includes a first plate and a second plate that are spaced apart. A connecting rod is fixed between the first plate and the second plate. A cylindrical sleeve is fixed between the first plate and the second plate. The inner hole of the cylindrical sleeve forms a through hole for the laser to pass through. The axis of the cylindrical sleeve is set in a corresponding manner to the 0° graduation line of the arc-shaped ruler 7.

[0027] The method for measuring the tilt angle of a building using the aforementioned building tilt angle measuring device includes the following steps: S1: Fix the fixing plate 2 on the inclined surface of the building to be measured, and set the support plate 3, which is vertically fixed on the fixing plate 2, perpendicular to the inclined surface of the building to be measured, and keep the projection of the support plate 3 on the vertical surface (i.e. the paper) perpendicular to the front and back direction as a straight line. S2: Let the plumb bob fixed at the origin 13 of the reflector 4 hang down naturally; S3: Use a laser rangefinder to measure the vertical distance H from the ground to the origin 13 of the reflector 4; S4: Adjust the height of the measuring ruler to be equal to the difference between the height distance H from the ground to the origin 13 of the reflector 4 and the radius R of the curved ruler 7, so that the center of the curved ruler 7 coincides with the origin 13 of the reflector 4. S5: Adjust the position of the measuring ruler, place the measuring ruler at the projection of the plumb bob on the ground, adjust the arc plate 7 of the measuring ruler to be perpendicular to the inclined surface of the building to be measured, so that the plane where the incident laser 9 and the reflected laser 10 are located coincides with the plane where the arc plate 7 is located, and at the same time, make the axis of the laser path 12 correspond to the origin 13 of the reflector 4. S6: Turn on the laser emitter 8 so that the laser passes through the laser path 12 from bottom to top and shines on the origin 13 of the reflector 4 to form the incident laser 9. The incident laser 9 corresponds to the 0° mark on the curved ruler 7. After being reflected by the reflector 4, it forms the reflected laser 10. The reflected laser 10 passes through the gap between the first plate and the second plate of the curved ruler 7. The angle of the reflected laser 10 on the curved ruler 7 is twice the building tilt angle.

[0028] The measurement principle of this application is as follows: When the inclined surface of the building to be measured is the first inclined surface 1, the angle α between the inclined surface and the vertical line is the inclination angle of the first inclined surface 1. Since the angle between the vertical line and the support plate 3 is β, and since the support plate 3 is perpendicular to the inclined surface of the building to be measured, the sum of α and β is 90°. The angle between the incident laser 9 and the reflector 4 is the same as the angle between the vertical line and the support plate 3. Therefore, the angle between the incident laser 9 and the reflector 4 is also β. Thus, the angle between the normal of the reflector 4 and the incident laser 9 is α. The angle between the incident laser 9 and the reflected laser 10 is 2α. The incident laser 9 corresponds to the 0° mark on the arc-shaped ruler 7. Therefore, the angle indicated by the reflected laser 10 is twice the inclination angle of the inclined surface of the building to be measured.

[0029] When the inclined surface of the building to be measured is the second inclined surface 11, the angle α between the inclined surface and the vertical line is the inclination angle of the second inclined surface 11. Since the angle between the vertical line and the reverse extension of the support plate 3 is β, and since the support plate 3 is perpendicular to the inclined surface of the building to be measured, the sum of α and β is 90°. The angle between the incident laser 9 and the reflector 4 is the same as the angle between the vertical line and the reverse extension of the support plate 3. Therefore, the angle between the incident laser 9 and the reflector 4 is also β. Thus, the angle between the normal of the reflector 4 and the incident laser 9 is α. The angle between the incident laser 9 and the reflected laser 10 is 2α. The incident laser 9 corresponds to the 0° mark on the curved ruler 7. Therefore, the angle indicated by the reflected laser 10 is twice the inclination angle of the inclined surface of the building to be measured.

[0030] In this invention, the fixed positions of the fixing plate 2 and the support plate 3 on the inclined surface of the building to be measured can be adjusted at will. The position of the measuring ruler can be adjusted according to the position of the fixing plate 2 and the support plate 3, thereby facilitating multiple measurements of the inclination angle of the inclined surface of the building to be measured. Moreover, by reflecting the laser to the measuring ruler, the reading can be easily taken on the measuring ruler.

[0032] In the above embodiments, the reflector is a circular plate; in other embodiments, the reflector is a rectangular plate.

[0033] In the above embodiments, the laser emitter is fixed on the support base and located at the bottom of the cylindrical cavity; in other embodiments, the laser emitter is fixed in the cylindrical cavity.
