[0002] In the field of building construction, surveying and setting out is a key link to ensure project quality and construction accuracy. Its accuracy directly affects the overall structure and functionality of the building. With the rapid development of the construction industry, engineering construction projects are becoming increasingly complex and diverse, which puts forward higher requirements for the functional integration and portability of surveying and setting out equipment.
[0003] Traditional line-laying instruments typically only have a single line-laying or distance-measuring function, which cannot meet the rapid response to various measurement needs on the construction site. This leads to construction personnel having to frequently change equipment, increasing construction costs and time costs.
[0004] Therefore, to address the shortcomings of traditional line-laying instruments, a foldable building surveying line-laying instrument can be designed. By integrating manual line laying and laser ranging into one unit, and by designing a corresponding hinge folding structure, it can be easily folded and carried, thereby solving the above problems. Utility Model Content

[0006] The technical solution is as follows: A foldable building surveying and setting-out instrument includes a base, a setting-out reel, a laser rangefinder, and a setting-out roll; a setting-out reel for manual setting-out measurement is located above the base, and a laser rangefinder for laser ranging is located above the setting-out reel; a setting-out groove is located in the center of the setting-out reel, and a setting-out roll for winding up and winding up the set-out roll is located inside the setting-out groove; a damping shaft is located between the base and the setting-out reel, and the base and the setting-out reel are movably connected through the damping shaft.
[0007] Furthermore, four sets of horizontal grooves are provided on the surface of the pay-off reel, and the four sets of horizontal grooves are evenly distributed at the corners of the surface of the pay-off reel. Each of the four sets of horizontal grooves is equipped with a liquid level bead.

[0023] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0024] As a pioneering step in engineering construction, architectural surveying provides indispensable data support for transforming buildings from design blueprints into reality. From towering skyscrapers to intricate underground utility tunnels, from bridges spanning rivers to extensive roads, the smooth implementation of every construction project relies on the precise control of architectural surveying technology.
[0025] Building surveying is a discipline that studies the spatial location of the Earth's surface and uses scientific measuring instruments and methods to collect, process, and analyze data related to the topography, landforms, and features of building construction projects. Its core task is to obtain accurate spatial information through measurement, provide basic data for the planning and design of building projects, conduct positioning, layout, and deformation monitoring during construction to ensure that the location, size, and shape of buildings meet design requirements, and provide data basis for acceptance and operation and maintenance after project completion.
[0026] Building surveying plays a crucial role in construction engineering. During the planning and design phase, topographic maps created through topographic surveying can visually demonstrate the terrain undulations and feature distribution of the construction area, helping designers to rationally plan building layouts and road directions, avoiding design defects caused by terrain factors. During the construction phase, surveying work directly affects whether the building can be constructed accurately according to the design drawings. For example, the positioning of the building's axis, the control of foundation excavation depth, and the transfer of floor elevations all rely on accurate measurements. Once measurement errors occur, it may lead to structural instability, inconsistent appearance, or even serious safety accidents. During the operation and maintenance phase, deformation monitoring can promptly detect subtle changes in the building caused by factors such as foundation settlement, wind, and earthquakes, providing a scientific basis for the building's safety assessment and maintenance reinforcement, ensuring the long-term stable operation of the building.
[0027] Construction surveying is the process of transferring the plan position and elevation of a building from the design drawings to the actual site using surveying instruments and methods. It includes building positioning, foundation layout, floor layout, and elevation transfer. Building positioning determines the specific location of the building on the ground, usually based on control points given by the planning department, using methods such as polar coordinate method, angle intersection method, and distance intersection method. Foundation layout, based on the building positioning, sets out the foundation excavation boundary line and foundation axis, providing a basis for foundation construction. Floor layout and elevation transfer ensure that the plan position and elevation of each floor of the building meet the design requirements, ensuring the verticality and floor height accuracy of the building.
[0028] The quality of building surveying directly affects the quality and safety of building projects. Therefore, it is essential to strengthen quality control. Before the surveying work begins, the surveying instruments must be rigorously inspected and calibrated to ensure that their accuracy meets the requirements. Surveyors should possess professional knowledge and skills and strictly follow surveying specifications and operating procedures. During the surveying process, methods such as redundant observations and closure error calculations should be used for quality checks to promptly identify and correct measurement errors. The recording and processing of measurement data should be accurate and standardized to ensure the authenticity and reliability of the data.
[0029] Example
[0030] like Figures 1-5 As shown, the foldable building surveying and setting-out instrument includes a base 1, a setting-out reel 2, a laser rangefinder 3, and a setting-out roll 5. The setting-out reel 2 for manual setting-out measurement is located above the base, and the laser rangefinder 3 for laser ranging is located above the setting-out reel 2. A setting-out groove 4 is opened in the center of the setting-out reel 2, and a setting-out roll 5 for winding up and winding up the setting-out roll 5 is located inside the setting-out groove 4. A damping shaft 23 is provided between the base and the setting-out reel 2, and the base and the setting-out reel 2 are movably connected through the damping shaft 23.
[0031] The surface of the pay-off reel 2 is provided with four sets of horizontal grooves 8, which are evenly distributed at the corners of the surface of the pay-off reel 2. Each of the four sets of horizontal grooves 8 is provided with a liquid level bead 9. The liquid level bead 9 can be used to intuitively determine whether the pay-off reel 2 is in a horizontal state, ensuring the accuracy of the measurement reference plane, avoiding pay-off errors caused by equipment tilting, and improving measurement accuracy. It is especially suitable for construction scenarios with high requirements for levelness.
[0032] The center of the winding groove is provided with an elastic roller 7, and the upper edge of the winding groove is provided with a limiting pressure strip 6. The front center of the wire feeding reel 2 is provided with a wire feeding port 10 that communicates with the winding groove. The elastic roller 7 can automatically wind up and wind down the wire feeding reel 5, reducing the tedious operation of manual wire winding and improving wire feeding efficiency. The limiting pressure strip 6 can prevent the wire feeding reel 5 from loosening or coming off during the winding and winding process, ensuring the stability and service life of the wire feeding reel 5. The wire feeding port 10 guides the wire feeding direction of the wire feeding reel 5, avoids cable tangling, and makes the wire feeding process smoother.
[0033] The wire reel 5 includes an elastic sleeve 501. The bottom of the elastic sleeve 501 has a sleeve opening 503 to accommodate the elastic reel 7. The top and bottom outer ends of the elastic sleeve 501 are both fitted with wire bundles 502. A winding groove 504 is formed between the wire bundles 502. The front end of the wire reel 2 is provided with a pull buckle 505 corresponding to the wire reel 5. The two ends of the wire reel 5 are fixed by the wire bundles 502 to prevent the cable from scattering. At the same time, the winding groove 504 can straighten the cable winding path and avoid knotting. The pull buckle 505 is used to fix the end of the wire reel 5, which makes it easy for construction personnel to accurately control the wire length.
[0034] The laser ranging disk 3 has a laser ranging module 14 (model LSP-LRS-1010A) at the front center. The surface of the laser ranging disk 3 has a display screen 11 and control buttons 12 corresponding to the laser ranging module 14. The laser ranging module 14 can quickly achieve accurate distance measurement, making up for the error defects of manual line laying in long-distance measurement. It is suitable for the measurement of large-span building structures. The control buttons 12 and the display screen 11 can adjust the displayed distance data in real time, which makes it easier for construction personnel to read the data and operate, thus improving the measurement efficiency.
[0035] The rear end of the laser rangefinder 3 is provided with a damping movable shaft 13. Two sets of movable connecting seats 15 are symmetrically provided at the edge of the rear end surface of the line-laying disc 2. A movable connecting hole 16 is opened through the center of the movable connecting seat 15. The two ends of the damping movable shaft 13 extend into the movable connecting holes 16 of the two sets of movable connecting seats 15 respectively. By cooperating with the movable connecting seats 15, the laser rangefinder 3 can rotate around the damping movable shaft 13, thereby realizing the adjustment of the pitch angle of the laser rangefinder 3 and meeting the multi-directional measurement needs in complex construction scenarios.
[0036] The base plate has four sets of horizontally adjustable telescopic legs 19 at its bottom, which are evenly distributed at the bottom corners of the base plate. The rear end of the base plate has a hook 17. The height of the equipment can be adjusted according to the flatness of the ground by adjusting the horizontally adjustable telescopic legs 19 to ensure the levelness of the base plate and the wire laying plate 2, adapting to the ground conditions of different construction sites. The hook 17 facilitates the hanging and storage of the equipment, saving storage space.
[0037] A battery compartment 20 is located at the bottom center of the base plate. A battery pack 21 is located inside the battery compartment 20. A battery sealing plate 22 is located at the bottom of the battery compartment 20. The battery pack 21 is electrically connected to the laser ranging module 14. A charging port 18 corresponding to the battery pack 21 is located on one side of the base plate. The laser ranging module 14 is powered by the built-in battery pack 21, eliminating the limitation of external power supply and supporting the use of the device in the absence of power. The battery pack 21 is cyclically charged through the charging port 18.
[0038] When working, the construction personnel arrive at the construction site with the folded measuring and laying instrument. They take it out of the tool bag using the hook 17. When unfolding the equipment, they first pull out the four sets of horizontal adjustment telescopic legs 19 at the bottom of the base plate. According to the actual flatness of the ground, they adjust the height of the four telescopic legs respectively. Then, the laser rangefinder 3 is rotated 180° along the movable connecting seat 15 through the damping movable shaft 13 so that it does not block the liquid level beads 9. By observing the liquid level beads 9 in the four sets of horizontal grooves 8 on the surface of the laying plate 2, when the liquid level beads 9 are in the center position of the horizontal grooves 8, it indicates that the laying plate 2 is in a horizontal state. At this time, the base plate is also in a stable horizontal state, and the initial setup of the equipment is completed.
[0039] For short-distance, precise layout, the construction worker opens the pull-wire buckle 505 at the front end of the layout reel 2 and pulls the measuring wire from the layout reel 5 in the layout groove 4. The measuring wire is guided out through the cable routing port 10 to avoid cable tangling. According to the measurement requirements, the construction worker pulls the measuring wire to the designated position and uses the pull-wire buckle 505 to secure the end of the measuring wire, completing the manual layout operation to determine the local dimensions and positional relationships of the building.
[0040] When performing long-distance measurements or measuring heights, such as measuring the distance between different floors or the span of a large space, the construction personnel press the control button 12 on the surface of the laser ranging disk 3 to start the laser ranging module 14. By rotating the damping movable shaft 13 of the laser ranging disk 3, the pitch angle can be adjusted, or the damping rotating shaft 23 can be rotated to drive the pay-off disk 2 and the laser ranging disk 3 to rotate in a circumferential direction, thereby adjusting its horizontal angle so that the laser beam is accurately aligned with the measurement target point. After the laser emitted by the laser ranging module 14 reaches the target point, it is reflected back, and the ranging data is displayed on the display screen 11 in real time. The construction personnel can adjust the data display mode as needed through the control button 12 to quickly obtain accurate measurement distances.
[0041] Its working principle is as follows: In the wire groove 4 at the center of the wire reel 2, the elastic reel 7 uses its own elasticity to generate contraction force to realize the automatic winding and unwinding of the wire reel 5. When the construction personnel pull out the measuring line, the elastic reel 7 is stretched by force and stores elastic potential energy. After the measurement is completed, the elastic potential energy is released, which drives the wire reel 5 to retract. The limiting pressure strip 6 limits the wire reel 5 during the winding and unwinding process to prevent the wire reel 5 from loosening or coming off. The wire outlet 10 provides a fixed wire exit channel for the measuring line, guiding the measuring line to be released and retracted in an orderly manner and avoiding cable tangling.
[0042] When the laser ranging module 14 inside the laser ranging disk 3 is working, it emits a laser beam toward the target point. After the laser beam encounters the target point, it is reflected back and received by the ranging module. By calculating the time from the emission to the reception of the laser beam, the distance from the measurement point to the target point is accurately calculated. The display screen 11 and the control button 12 constitute a human-machine interface. The control button 12 is used to start and stop ranging and adjust the data display mode. The display screen 11 displays the ranging data in real time, which is convenient for construction personnel to operate and read.
[0043] The horizontal adjustment telescopic leg 19 at the bottom of the base plate makes the base plate and the line-laying plate 2 reach a horizontal state. The laser rangefinder 3 is connected to the movable connecting seat 15 at the rear end of the line-laying plate 2 through the damping movable shaft 13. The damping movable shaft 13 can rotate in the movable connecting hole 16. The construction personnel can manually rotate the laser rangefinder 3 to adjust its pitch angle, so that the laser beam can be aimed at the measurement target at different heights and angles. The damping rotating shaft 23 drives the line-laying plate 2 and the laser rangefinder 3 to rotate in a circle, thereby adjusting their horizontal angle.
[0044] Its beneficial effects are significant. This application integrates manual line laying and laser ranging functions through the line laying disc 2 and the laser ranging disc 3. Construction personnel do not need to frequently change equipment. The manual line laying function is used for short-distance measurement, and the laser ranging function is used for long-distance measurement. It can quickly respond to various measurement needs on the construction site, greatly shorten the measurement time, and significantly improve the measurement efficiency.
[0045] The liquid level bead 9 can intuitively determine whether the laying reel 2 is level, ensuring the accuracy of the measurement reference plane; the laser ranging module 14 can achieve accurate distance measurement over long distances, making up for the error defects of manual laying out when measuring over long distances; the horizontal adjustment telescopic leg 19 can adapt to different ground conditions and ensure the levelness of the equipment. These designs work together to significantly improve the measurement accuracy, effectively avoid construction rework caused by measurement errors, and ensure the overall structure and functionality of the building.
[0046] The laser rangefinder 3 can adjust the pitch and horizontal angles to meet the multi-directional measurement needs in complex construction scenarios; the built-in battery pack 21 powers the laser rangefinder module 14, eliminating the limitation of external power supply and enabling the equipment to be used normally at construction sites without power; the foldable design and hook 17 make the equipment easy to carry and store, enhancing its applicability in different construction environments.
