Technical Field

[0001] The utility model relates to the technical field of construction surveying and mapping tools, and particularly relates to a leveling instrument scale measuring device for quickly and accurately measuring building elevations. Background Art

[0002] At present, the leveling tower rod is commonly used for the leveling instrument scale. The leveling tower rod is a scale used for leveling measurement and is made of high-quality aluminum alloy. In the actual use process, the leveling tower rod needs to be placed vertically. However, due to environmental and human factors, when measuring the elevation 50 line of the floor, the elevation control point needs to be marked on the steel bars of the structural column. Due to the influence of the stirrups on the column steel bars, the tower rod cannot be closely attached to the vertical steel bars of the structural column, resulting in the inclination of the tower rod and errors during line drawing, not meeting the accuracy requirements. At the same time, the instability of the tower rod held by the surveyor for a long time causes the tower rod to slide easily and the measurement efficiency is low. Summary of the Invention

[0003] The utility model provides a leveling instrument scale measuring device for quickly and accurately measuring building elevations to solve the technical problems of low measurement accuracy and low measurement efficiency of the traditional measurement method when measuring the elevation 50 line of the floor.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further illustrates the present utility model in conjunction with specific embodiments. Embodiment 1

[0017] As Figure 1 and 2As shown in the figure, a leveling rod measuring device for quickly and accurately measuring the building elevation includes a rotating base. A leveling pad base 2 is fixed on the top of the rotating base. The leveling pad base 2 is connected to a leveling rod 1 through a leveling rod fastening and adjusting bolt 16. A horizontal benchmark 12 is fixedly connected to one side of the leveling pad base 2. A connecting member 9 is fixedly connected to the side of the rotating base. One end of the connecting member 9 away from the rotating base is connected to a vertically movable adjusting member. The vertically movable adjusting member is provided with a vertical block 18. A clamping assembly is fixedly connected to the side of the vertical block 18 away from the connecting member 9. One end of the rotating base away from the connecting member 9 is connected to a horizontal bubble support 7, and a horizontal bubble 8 is provided on the horizontal bubble support 7. The structure of the connecting member 9 can be any structure that can connect the rotating base and the vertically movable adjusting member together.

[0018] Further, the rotating base includes a detachable upper base 4 and a lower base 5. A rotating shaft is provided at the center of the upper base 4 and the lower base 5, and a top plate 3 located above the upper base 4 and a bottom plate 6 located below the lower base 5 are fixedly connected to both ends of the rotating shaft respectively. The leveling pad base 2 is fixed above the top plate 3. The top plate 3 and the bottom plate 6 can rotate relative to the upper base 4 and the lower base 5.

[0019] Further, the vertically movable adjusting member includes a support base 15. A vertically adjusting bolt 13 horizontally arranged is screwed on the support base 15. A gear disk is sleeved at the end of the vertically adjusting bolt 13. The gear disk meshes with a vertically arranged threaded column. The outside of the threaded column is sleeved with a vertical block 18. Sliders are also provided on both sides of the vertical block 18. Corresponding positions on the inner side of the support base 15 are provided with chutes matching the sliders, and the sliders are slidably arranged in the chutes.

[0020] By screwing the vertically adjusting bolt 13 to drive the gear disk to rotate, since the threaded column meshed with it has been fixed to the column steel bar 11 through the clamping assembly due to the vertical block 18 sleeved on the outside, the gear disk drives the support base to move up and down in the vertical direction, thereby adjusting the height of one end of the leveling pad base 2. By controlling the clockwise or counterclockwise rotation of the vertically adjusting bolt 13, the leveling rod 1 and the leveling pad base 2 can be moved up or down.

[0021] Further, the clamping assembly includes clamping legs 10 fixedly connected to the front and rear sides of the vertical block 18 respectively. First fastening and adjusting nuts 14 are screwed on the clamping legs 10. The device of the present invention is clamped on the column steel bar 11 through the first fastening and adjusting nuts 14 on both sides.

[0022] Further, the support base 15 and the connecting member 9 are connected through a second fastening and adjusting nut 17.

[0023] Working process: Clamp the device of the present utility model on the column steel bar 11 through the first fastening and adjusting nuts 14 on both sides. Make the device horizontally set as a whole by observing the level bubble 8. Fasten the leveling staff 1 through the leveling staff fastening and adjusting bolt 16. Adjust the height of one end of the leveling pad base 2 by screwing the vertical adjusting bolt 13 to make the data of the leveling staff 1 in the correct position. At this time, keep the force of the hand on the vertical adjusting bolt 13 so that the leveling staff 1 is in the correct position (for convenient use, the vertical adjusting bolt 13 can be replaced with a motor to control the rotation and start / stop of the gear disk). Then quickly rotate the horizontal benchmark 12 to the corresponding position of the column steel bar 11 to make corresponding marks.
