[0002] Building construction refers to various technical works such as surveying, planning, design, construction, installation, and maintenance for the construction, reconstruction, or expansion of buildings and ancillary structures. In order to complete various building construction works, measurement operations are required, and measurement benchmarks are generally used in measurement operations.

[0003] The current benchmark for building construction measurement, such as "A Benchmark for Building Construction Measurement" proposed in the patent number 202221594927.9, mainly includes a fixed pile, a horizontal platform, a level, a rod body, and support feet. The horizontal platform is installed on the top of the fixed pile, the level is installed on the horizontal platform, the rod body is vertically installed on the horizontal platform, and three support feet are evenly installed on the fixed pile along the circumferential direction of the fixed pile; the support feet include a fixed sleeve and a telescopic rod. The top end of the fixed sleeve is installed on the fixed pile, and the fixed sleeve and the telescopic rod are threadedly connected; the bottom end of the fixed pile is a tip for facilitating insertion into soft ground; scale lines are provided on the rod body; through the three-legged support structure, a good support effect is achieved, and there is no need for manual holding and support, which saves time and effort; by adjusting the lengths of the support feet respectively, it can be leveled and used in different terrain environments, and at the same time, the original bottom tip is retained for insertion into soft ground for fixation, enhancing the practicability.

[0004] The existing benchmark for building construction measurement is supported by a triangular bracket with adjustable length. Although it can play a role in fixing and supporting the measurement benchmark, in the actual use process, the benchmark is prone to overall tipping due to being touched, and its stability cannot be further improved, and the accuracy during the measurement process cannot be guaranteed.

An open groove 16 is provided on the outside of the insertion rod 4 near the cavity 14, and a protrusion 17 is horizontally slidably connected inside the open groove 16. A spring 18 is fixedly connected between the protrusion 17 and the inner wall of the cavity 14. A threaded groove 19 is provided on the top of the movable plate 15, and the longitudinal movement distance of the movable plate 15 is controlled by an adjustment mechanism inside the fixed seat 3 and the insertion rod 4.

[0025] After the insertion rod 4 is inserted into the soil, the rotating rod 24 can be rotated, and the movable plate 15 can be driven to move downward through the adjustment mechanism to resist the protrusion 17. As the movable plate 15 moves, the protrusion 17 can be squeezed, and the protrusion 17 can be pushed out laterally from the opening groove 16. The spring 18 is compressed by force, and the outer end of the protrusion 17 is a sharper V-shape, which can be easily inserted laterally into the soil. The contact area between the insertion rod 4 and the ground is increased by the protrusion 17, thereby improving the overall stability of the device. Then the threaded extension rod 7 can be taken out of the U-shaped holder 8 and rotated to the ground for support, which further enhances the stability of the device and is convenient to use.

[0026] The horizontal display device includes a groove 10, an angle plate 11, a pull rope 12 and a counterweight 13.

[0032] In the present utility model, when relevant technical personnel use the device, insert the insertion rod 4 into the soil. The angle of the pull rope 12 on the angle scale 11 can be observed. When the pull rope 12 deviates from the central axis of the angle scale 11, the position of the insertion rod 4 can be adjusted in a timely manner until the pull rope 12 coincides with the central axis of the angle scale 11. At this time, the whole device can be leveled.

[0033] After that, the rotating rod 24 can be rotated. Through the adjusting mechanism, the moving plate 15 can be driven to move downward, pressing against the convex block 17. As the moving plate 15 moves, the convex block 17 can be extruded, and the convex block 17 can be horizontally pushed out from the opening groove 16. The spring 18 is compressed under force. The outer end of the convex block 17 is a relatively sharp V shape, which can be easily inserted horizontally into the soil. By the convex block 17, the contact area between the inserting rod 4 and the ground is increased, improving the overall stability of the device.
