Description

Technical Field

[0001] This utility model relates to the field of building inspection, specifically a device for detecting the verticality of a building's main structure. Background Technology

[0002] During the construction of the main building structure, verticality needs to be measured to determine whether it is up to standard. To ensure the accuracy of the measurement values, the measuring device needs to be in a horizontal position before measuring verticality. However, due to the influence of the construction site environment, a level is often required for auxiliary adjustment. For example, the verticality detection device for the surface of the main building structure disclosed in CN218270777U and the detection device for the main building structure disclosed in CN220251039U both use bolts to adjust the support height of different support legs for horizontal verification. The adjustment efficiency is low, and frequent adjustments are required when measuring different positions, which is time-consuming, labor-intensive, and impractical. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model adopts a verticality detection device for the main structure of a building, which solves the problems of low efficiency of horizontal verification and the need for multiple adjustments in the prior art.

[0004] The technical solution is a device for detecting the verticality of a building's main structure, comprising a support base with four circumferentially distributed legs fixed to its lower end. A through hole is formed in the center of the support base, penetrating both the upper and lower surfaces. A horizontal plate is positioned above the support base, with a hemispherical block fixed to its lower end. The lower end of the hemispherical block passes through the through hole and can rotate freely. A vertical rod is fixed to the lower end of the hemispherical block, perpendicular to the horizontal plate, and a weight is fixed to its lower end. Two support rods are fixed to the right end of the horizontal plate, one in front and one behind. A horizontally placed support rod is fixed between the two support rods. A horizontal bar is provided, on which a first slider is provided that can slide and rotate along the axis of the first horizontal bar. A first measuring rod is fixed to the right end of the first slider. Four blind holes are provided on the upper surface of the support base, which are evenly distributed around the circumference. A piston rod that can move up and down is provided in each blind hole. The piston rod always seals the upper opening of the blind hole. The upper end of each piston rod is always in contact with the lower end of the horizontal plate. A connecting hole is provided between every two adjacent blind holes on the lower side of the piston rod. A valve is provided in the middle of each connecting hole. The valve can open or close the connecting hole.

[0005] The horizontal plate has a first connecting rod hinged to the middle of the front and rear end faces, and a second connecting rod hinged to the other end of each first connecting rod. A second crossbar is fixed between the two second connecting rods. A second slider that can slide and rotate along the axis of the second crossbar is provided on the second crossbar. The right end face of the second slider is fixedly connected to the upper end of the first measuring rod.

[0006] The distance between the rotation axis of the first slider and the rotation axis of the second slider is equal to the distance between the hinge axes at both ends of the first connecting rod, and the distance between the hinge axis of the first connecting rod and the horizontal plate and the rotation axis of the first slider is equal to the distance between the hinge axes at both ends of the second connecting rod.

[0007] A semi-circular degree plate is fixed to the upper surface of the horizontal plate. One end of the degree plate is attached to one of the first connecting rods, and the attachment surface is marked with angle scale.

[0008] The valve includes a vertically arranged rotating shaft in the middle of the connecting hole, with a baffle fixed on the rotating shaft. The baffle has the same cross-sectional shape as the connecting hole. When the baffle rotates around the axis of the rotating shaft to a position perpendicular to the axis of the connecting hole, it can block the connecting hole. At other positions, the connecting hole is open. The lower end of the rotating shaft passes through the lower end face of the support base and is fixedly connected to a gear. The lower end face of the support base is located outside all the gears and is rotatably connected to an internal gear ring through a bearing. The internal gear ring meshes with all the gears, and a short rod is fixed to the outer end of the internal gear ring.

[0009] The inner edge of the through hole is provided with multiple rolling ball blocks evenly distributed along the circumference.

[0010] A second measuring rod is arranged parallel to the right side of the first measuring rod. A telescopic rod is provided between the second measuring rod and the first measuring rod. The telescopic rod ensures that the second measuring rod always moves horizontally with the first measuring rod. A compression spring is provided between the first measuring rod and the second measuring rod.

[0011] This utility model has the following advantages over the prior art:

[0012] 1. A weight is connected to the underside of the hemispherical block via a vertical rod, which ensures that the horizontal plate remains horizontal under the weight of the weight, providing a horizontal reference.

[0013] 2. By rotating the short rod to control the valve opening and closing, the piston rod is locked in place and cannot move up or down, which can position the horizontal plate and avoid errors in the degree reading caused by shaking or accidental collision during the measurement process;

[0014] 3. The first measuring rod, the first connecting rod, the second connecting rod and the horizontal plate together form a parallelogram structure. The tilt angle of the first connecting rod is always consistent with that of the first measuring rod. The measuring personnel can obtain the tilt angle of the first connecting rod through the degree plate to determine the verticality of this part of the cavity.

[0015] 4. By allowing the first and second sliders to slide back and forth along the first and second crossbars, and cooperating with the compression springs between the first and second measuring rods, the second measuring rod is kept in contact with the wall surface at all times, compensating for the skew error caused during translation. The entire measurement process does not require moving the support base for repositioning, greatly improving measurement efficiency. Attached Figure Description

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Depend on Figures 1 to 5 The present invention includes a support base 1, with four circumferentially distributed legs 2 fixed to the lower end of the support base 1. A through hole 3 is provided in the middle of the support base 1, penetrating the upper and lower end faces. A horizontal plate 4 is provided above the support base 1, with a hemispherical block 5 fixed to the lower end of the horizontal plate 4. The lower end of the hemispherical block 5 passes through the through hole 3 and can rotate freely. A vertical rod 6 is fixed to the lower end of the hemispherical block 5, perpendicular to the horizontal plate 4, and a weight 7 is fixed to its lower end. Two support rods 8 are fixed to the right end face of the horizontal plate 4, and a first horizontal bar 9, horizontally placed front to back, is fixed between the two support rods 8. A feature is provided on the first horizontal bar 9 that allows movement along... The first slider 10 slides and rotates along the axis of the first horizontal bar 9. The right end of the first slider 10 is fixed with a vertically placed first measuring rod 11. The upper surface of the support base 1 has four blind holes 12 evenly distributed along the circumference. Each blind hole 12 is provided with a piston rod 13 that can move up and down. The piston rod 13 always seals the upper opening of the blind hole 12. The upper end of each piston rod 13 is always in contact with the lower surface of the horizontal plate 4. A connecting hole 14 is provided between every two adjacent blind holes 12 on the lower side of the piston rod 13. A valve is provided in the middle of each connecting hole 14. The valve can open or close the connecting hole 14.

[0023] The horizontal plate 4 has a first connecting rod 15 hinged to the middle of the front and rear end faces, and a second connecting rod 16 hinged to the other end of each first connecting rod 15. A second crossbar 17 is fixed between the two second connecting rods 16. A second slider 18 is provided on the second crossbar 17, which can slide and rotate along the axis of the second crossbar 17. The right end face of the second slider 18 is fixedly connected to the upper end of the first measuring rod 11.

[0024] The distance between the rotation axis of the first slider 10 and the rotation axis of the second slider 18 is equal to the distance between the hinge axes at both ends of the first connecting rod 15, and the distance between the hinge axis of the first connecting rod 15 and the horizontal plate 4 and the rotation axis of the first slider 10 is equal to the distance between the hinge axes at both ends of the second connecting rod 16.

[0025] A semi-circular degree plate 19 is fixed on the upper surface of the horizontal plate 4. One end of the degree plate 19 is attached to one of the first connecting rods 15, and the attachment surface is marked with angle scale.

[0026] The valve 15 includes a vertically arranged rotating shaft 20 in the middle of the connecting hole 14. A baffle 21 is fixed on the rotating shaft 20. The baffle 21 has the same cross-sectional shape as the connecting hole 14. When the baffle 21 rotates around the axis of the rotating shaft to a position perpendicular to the axis of the connecting hole 14, it can block the connecting hole 14. At other positions, the connecting hole 14 is open. The lower end of the rotating shaft 20 passes through the lower end face of the support base 1 and is fixedly connected to a gear 22. The lower end face of the support base 1 is located outside all the gears 22 and is rotatably connected to an internal gear ring 23 through a bearing. The internal gear ring 23 meshes with all the gears 22. A short rod 24 is fixed to the outer end of the internal gear ring 23.

[0027] The inner edge of the through hole 3 is provided with a plurality of circumferentially distributed rolling ball blocks 25.

[0028] A second measuring rod 26 is arranged parallel to the right side of the first measuring rod 11. A telescopic rod 27 is provided between the second measuring rod 26 and the first measuring rod 11. The telescopic rod 27 ensures that the second measuring rod 26 always moves horizontally relative to the first measuring rod 11. A compression spring is provided between the first measuring rod 11 and the second measuring rod 26.

[0029] In use, this invention first rotates the internal gear ring 23 via the short rod 24, causing all gears 22 to drive the rotating shaft 20 and baffle 21 to rotate to the position where all connecting holes 14 are opened, making all blind holes 12 interconnected. At this time, all piston rods 13 can rotate freely with the horizontal plate 4. Then, the support base 1 is moved to the wall to be measured, so that the second measuring rod 26 abuts against the wall and the compression spring is in a compressed state. Since the hemispherical block 5 is rotatably connected to the through hole 3 through ball bearings, and the lower side of the hemispherical block 5 is connected to the weight 7 through the vertical rod 7, the horizontal plate 4 can always remain horizontal under the gravity of the weight 7. Then, the short rod 24 is rotated to close all valves, and each blind hole 12 forms a sealed cavity. The position of the piston rod 13 is locked and cannot move up or down, which can position the horizontal plate 4 and avoid the degree caused by shaking or accidental collision during the measurement process. When an error occurs, since the first measuring rod 11, the first connecting rod 15, the second connecting rod 16, and the horizontal plate 4 together form a parallelogram structure, the tilt angle of the first connecting rod 15 is always consistent with that of the first measuring rod 11. The measuring personnel can obtain the tilt angle of the first connecting rod 15 through the degree plate 19 to determine the verticality of that part of the cavity. When it is necessary to measure adjacent areas, it is only necessary to move the first measuring rod 11 horizontally back and forth, so that the first slider 10 and the second slider 18 slide back and forth along the first horizontal bar 9 and the second horizontal bar 17. Even if the translation direction of the first slider 10 and the second slider 18 is not parallel to the wall, the second measuring rod 26 can always be in contact with the wall through the extension and contraction of the compression spring, which can make up for the skew error caused by translation. The entire measurement process does not require moving the support base 1 for repositioning, which greatly improves the measurement efficiency.
