[0002] Construction surveying refers to the surveying work carried out for construction control, layout and final acceptance. During or after construction, it is necessary to measure the inclination of the building's walls to check whether the angle between the measured wall and the ground is consistent with the design.

[0003] When measuring measuring points at higher locations on buildings, traditional construction measurement devices cannot adjust the height of the measurement devices according to different construction scenarios and needs. This requires workers to use auxiliary tools such as ladders and scaffolding to carry the measurement devices to the measurement points. In some narrow spaces or complex terrains, it is not convenient to set up auxiliary tools, which is quite inconvenient. This not only increases the complexity and danger of the operation, but also brings great difficulties to the measurement work.

[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0029] like Figure 1-7As shown, a construction measurement device includes a base 1, the base 1 is sleeved with a protective shell 2, the protective shell 2 is sleeved with a lifting rod 3, the lifting rod 3 is sleeved and rotatably connected to a connecting rod 4, the lifting rod 3 is engaged with two pawls 6 fixed on the connecting rod 4 through a ratchet 5 fixed on the lifting rod 3, the top of the connecting rod 4 is fixedly installed with a mounting platform 7, a moving rod 9 is threadedly connected to the mounting platform 7 through a screw rod 8, one end of the moving rod 9 extends to the outside of the mounting platform 7 and is fixed with a bracket 10, a vertical measuring ruler 11 is hinged on the bracket 10, and one side of the bracket 10 is connected to a pendant 13 through a vertical rope 12.

[0030] The base 1 is tubular in shape, with three support plates 14 welded to its outer wall in a circular array. Anchor bolts 15 are threaded onto these support plates 14, with the bolt ends facing downward and secured to support plates 16. Because the ground at construction sites is often uneven, turning the anchor bolts 15 lowers the support plates 16 into contact with the ground, providing a stable support platform for the measuring device. Several first through-holes 17 are formed in the outer wall near the top of the base 1, arranged in a horizontal circular array.

[0031] The protective housing 2 is tubular in shape, with a sealed bottom end. A vertically arranged limit plate 18 is provided on the inner wall of the protective housing 2. A retaining ring 19 is provided on the sealed end and the outer wall at the lower middle position of the protective housing 2 to retain the base 1 between the two retaining rings 19 of the protective housing 2. A plurality of first internal thread holes 20 are provided on the protective housing 2 between the two retaining rings 19. A plurality of second through holes 21 are provided on the outer wall of the protective housing 2 above the retaining rings 19. The first and second through holes 20, 21 are vertically and linearly distributed about the position of the limit plate 18. A handle 22 is fixed to the outer wall of the protective housing 2. A first bolt 23 is inserted into the first through hole 17 aligned with the first internal thread hole 20. The first bolt 23 is threaded into the first internal thread hole 20 to secure the protective housing 2 to the base 1. A buffer base 24 is installed at the bottom end of the protective housing 2 to cushion the contact between the protective housing 2 and the ground.

[0032] A strip groove 25 is defined on the outer wall of the lifting rod 3. The bottom end of the strip groove 25 is open, and the top end is sealed. The strip groove 25 receives the stop plate 18, thereby preventing the lifting rod 3 from rotating within the protective housing 2. Within the strip groove 25, the lifting rod 3 is provided with a plurality of second internal threaded holes 26, distributed linearly in a vertical direction. Each second internal threaded hole 26 is threadedly connected to a second bolt 29 extending through the second through hole 21 to secure the lifting rod 3. A circular groove 27 is defined at the top end of the lifting rod 3 for mounting the connecting rod 4.

[0033] The connecting rod 4 is connected to the circular groove 27 by a bearing, and the ratchet 5 is fixed in the circular groove 27. There are notches on both sides of the connecting rod 4, and two pawls 6 are respectively located in the two notches. The pawls 6 are arc-shaped, and the engaging ends of the pawls 6 are convex.

[0034] The interior of the mounting platform 7 is hollow, and the screw rod 8 passes through and is rotatably connected to one end of the mounting platform 7 and then rotatably connected to the inside of the other end of the mounting platform 7. The moving rod 9 has a door-shaped structure. The moving rod 9 is threadedly connected to the screw rod 8 inside the mounting platform 7. The two ends of the door-shaped structure of the moving rod 9 pass through the mounting platform 7 and are connected to the bracket 10.

[0035] The bracket 10 has a gate-shaped structure, and the internal rotation of the gate-shaped structure of the bracket 10 is connected to the hinge rod 28. The vertical measuring ruler 11 has a gate-shaped structure, and the center position of the vertical measuring ruler 11 is connected to and fixed at the center position of the hinge rod 28. The vertical measuring ruler 11 is hinged to the bracket 10 through the hinge rod 28.

[0036] The working principle of this utility model is:

[0037] First, when it is necessary to measure the construction, place the vertical measuring ruler 11 against the wall, and make the two ends of the gate-shaped structure of the vertical measuring ruler 11 close to the wall, and observe whether the vertical measuring ruler 11 is tilted relative to the pendant 13. Turn the screw 8, and the screw 8 drives the moving rod 9 to move and move the bracket 10 away from the mounting platform 7, so that the bracket 10 can measure a farther position. When it is necessary to rotate the vertical measuring ruler 11, the mounting platform 7 drives the pawl 6 to move through the connecting rod 4 and contact with the ratchet 5, so that it can rotate in sections. When it is necessary to measure a higher area, pull out the lifting rod 3, and when it is adjusted to the required height, use the second bolt 29 to insert it into the second through hole 21 and the second inner thread hole 26 to fix the lifting rod 3. Since the ground at the construction site is often uneven, when the anchor bolt 15 is turned, the support plate 16 is lowered and in contact with the ground, which can provide a stable support platform for the measuring device. When adjusting the angle and height from the bottom of the utility model, the protective shell 2 can be loosened or fixed on the base 1 by screwing the first bolt 23. When loosened, the protective shell 2 can rotate freely and move up and down. After adjusting the angle and height, tighten the first bolt 23 to fix it.

Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention.
