[0002] Elevation measurement refers to the process of measuring the vertical height of the ground, structures or other objects. This measurement is usually used in civil engineering, construction and geographic surveying to determine the height difference or relative height between different locations. When measuring elevation, professional measuring equipment such as level, total station or laser rangefinder is required, and the elevation position is determined with a ruler.

[0003] When measuring the elevation on the construction panel, it is necessary to use measuring instruments such as a level to observe the scale lines on the elevation to judge the elevation position. The elevation needs to be placed on the steel bars to facilitate leaving elevation marks on the steel bars. When the steel bar skeleton is dense and the adjacent steel bars block the level's line of sight, the level cannot directly observe the scale lines on one side of the ruler, which is not conducive to leaving elevation marks on the position where the ruler is placed. Utility Model Content

[0018] In this embodiment: the ruler body 1 is used for construction surveyors to perform elevation positioning work during floor construction. By placing the ruler body 1 against the steel bars on the floor surface, the surveyors can observe the scale lines on the ruler body 1 through the level meter to measure the height. Since the level meter is set at a fixed position, when the level meter is used to perform elevation positioning work on steel bars at different positions, when the level meter and the steel bar position to be measured and positioned need to be positioned at the steel bar skeleton position, and since the steel bar skeleton is relatively dense, the ruler body 1 is attached to the steel bar skeleton for positioning. After the level meter is leveled, the height is fixed, which is easy to use The sight line of the level instrument is blocked by the steel bar, so that the level instrument cannot directly observe the scale line on one side of the scale body 1, which is not conducive to the elevation positioning of the steel bar at the position where the scale body 1 is attached, and it is impossible to ensure that when measuring the 50-centimeter casting line, the steel bar at a certain position needs to be wrapped with tape. At this time, the scale body 1 is blocked, which is not conducive to observing the scale line on the level instrument, which is not conducive to the surveyor to adjust the height of the scale body 1, resulting in the inability to wrap the tape. At this time, the device can use the installation grooves 11 opened on both sides of it to make the mounting plate 2 correspond to the mounting grooves 11, so that it can be installed on the scale On both sides of the ruler body 1, the slide groove 22 provided on the mounting plate 2 allows the frame rod 24 to be inserted into the inner wall thereof. According to the position of the steel bar to be blocked, the frame rod 24 is installed in the slide groove 22 at a position displaced from the steel bar. After the frame rod 24 is inserted into the slide groove 22, one end of the frame rod 24 can be connected to the thread groove 231 provided on the measuring plate 23 and corresponding to the slide groove 22 through the connector 241, so that the measuring plate 23 can be installed under the frame rod 24, so that the measuring plate 23 can be kept horizontally corresponding to one side of the ruler body 1, so that the scale lines on the measuring plate 23 can match the scale lines on one side of the ruler body 1, so that the measuring plate 23 can be installed horizontally corresponding to the ... The measuring plate 23 can bypass the obstructed steel bars through the rack 24, so that the spirit level can directly observe the scale lines on the measuring plate 23. Since the measuring plate 23 corresponds to the scale body 1, the staff can measure and locate the elevation height of the position according to the scale lines on the measuring plate 23, so that the device can facilitate the surveying personnel to perform elevation positioning work on steel bars at any position, avoiding the need to change the elevation positioning position after being obstructed by nearby steel bars. Since the concrete panel has not been poured at this time, it is not convenient to transfer it, and at the same time avoid adjusting the position of the spirit level, thereby facilitating the surveying personnel to perform elevation positioning work required for concrete pouring.

The sliding rod 34 passes through the clamping plate 33, and a spring 341 is fixedly connected between the clamping plate 33 and the fixed plate 32. The spring 341 is sleeved on the outer wall of the sliding rod 34; the two fixed plates 32 fixedly connected to one side of the slide plate 3 are used to install and fix the sliding rod 34, so that the clamping plate 33 is limited on the sliding rod 34 by the penetration of the sliding rod 34, so that the clamping plate 33 slides horizontally on the sliding rod 34, and the clamping plate 33 is supported by the spring 341, so that the two clamping plates 33 can be clamped on the steel bar when the device is in use, and the upper and lower groups of clamping plates 33 are clamped on the steel bar, so that the ruler body 1 can correspond vertically to the steel bar to ensure its verticality.

[0023] The working principle and use process of the utility model are as follows: when the device is used to perform elevation measurement, by attaching the ruler body 1 to the steel bar, when the scale on the ruler body 1 is blocked by the nearby steel bar skeleton, two mounting plates 2 can be mounted on both sides of the ruler body 1, so that the measuring plate 23 is inserted on the mounting plate 2 through the frame rod 24, and the measuring plate 23 is erected in front of the mounting plate 2. The measuring plate 23 is provided with scale lines matching the ruler body 1, so that the staff can measure and locate the elevation height of the position according to the scale lines on the measuring plate 23, so that the device can facilitate the surveying personnel to perform elevation positioning work on the steel bars at any position, avoid the need to change the elevation positioning position after being blocked by the nearby steel bars, because the concrete panel is not poured at this time and it is not convenient to transfer, and at the same time avoid adjusting the position of the level, so as to facilitate the surveying personnel to perform elevation positioning work required for concrete pouring.
