[0002] With social development and the increasing demands on building structures for work and life, as well as the continuous improvement of modern architectural design, building structures are becoming increasingly diversified, technologically advanced, and three-dimensional. Therefore, during construction surveying, we often encounter buildings with complex plan and elevation designs, such as irregularly shaped buildings like arcs and ellipses, especially large public buildings like stadiums and exhibition halls, which often employ arc or elliptical designs. The construction layout for this type of building is more complex than for simple geometric shapes like rectangles and circles, requiring various surveying and layout methods, some of which are cumbersome and difficult to guarantee in terms of accuracy.
[0003] Traditional methods of marking lines with a steel ruler can be challenging due to obstacles such as reinforcing bars, formwork, steel pipes, and fasteners on the floors, affecting the measuring distance and requiring the clearing of these material obstructions from the measurement path. This adds difficulty to construction layout and can impact the construction schedule. In building construction, significant errors in the layout may necessitate the demolition and reconstruction of existing sections, wasting considerable manpower, resources, and time, and potentially affecting the entire project's progress.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0028] See Figure 1 This document illustrates a flowchart of a method for measuring and setting out building floors according to the present invention. The present invention provides a method for measuring and setting out building floors, comprising the following steps:
[0029] Perform step S110: Lay out the lines on the first floor of the building and obtain multiple control points using a total station.
[0030] During the layout of the first floor, the total station should be positioned to ensure a wide field of view, good visibility, and ease of operation for construction personnel, so as to ensure that all control points and layout points can be observed. The layout of each floor involves marking the floor plan with horizontal coordinates, which allows for the location of building axes, frame columns, and feature points. Accurate layout is then performed using the total station starting from the first floor, providing accurate basic control points for subsequent floor layout construction. Next, step S120 is executed.
[0031] Execution step S120: On the second floor of the building, set up multiple laying holes based on the multiple control points obtained from the first floor.
[0032] The number of holes for laying out the lines is set according to the actual construction needs and is not specifically limited here. Next, step S130 is executed.
[0033] Step S130: Use a total station to lay out the lines at multiple laying holes.
[0034] When using a total station, it is necessary to level the instrument, ensure a wide field of view, and guarantee the accuracy and stability of the total station to ensure the precision of the values. Measure the instrument height and input it accurately. The instrument height measurement is related to subsequent elevation calculations and can improve data accuracy. Then, proceed to step S140.
[0035] Perform step S140: Provide a reflector, connect the reflector to the total station, and take measurements on the second floor.
[0036] Among them, when using reflective sheets to assist construction, it is necessary to avoid strong light environments. When constructing at night, a flashlight can be used to assist in positioning. Then, step S150 is executed.
[0037] Perform step S150: Repeat the above operation until the measurement of all floors in the building is completed.
[0038] In the actual layout construction process, the coordinates of the points to be laid out can be input into the total station based on the coordinate data on the architectural design drawings. The total station will calculate the angle and distance that the instrument needs to rotate based on the current station coordinates, backsight direction and input layout point coordinates. The operator moves the reflector to the corresponding position according to the instructions of the total station, thereby completing the layout work of each point.
[0039] In this embodiment, the total station needs to be verified before use. During the verification process, the measured coordinates are compared and analyzed with the known control point coordinates. If the deviation between the two is within the error range, it indicates that the station data is accurate and reliable, and the subsequent layout work can continue. If the deviation exceeds the error range, it is necessary to re-check the instrument settings, centering and leveling, and whether the coordinate input is correct, find the problem and correct it until the accuracy requirements are met.
[0040] See Figure 2 The diagram shows a flowchart of step S110 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S110 includes:
[0041] Step S111: Provide the known coordinates of the control points to obtain the field control network.
[0042] The coordinates of known control points were calculated by combining preliminary surveys with architectural design drawings.
[0043] See Figure 3 This diagram illustrates another step S110 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S110 further includes:
[0044] Execute step S112: Use a total station to lay out the first control point, the second control point, and the third control point.
[0045] The obtained first, second, and third control points can establish a standardized coordinate system, reducing the impact of human experience differences on the measurement results and making the measurement work more reproducible and stable.
[0046] See Figure 4 The diagram shows a flowchart of step S120 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S120 includes:
[0047] Execution step S121: Based on the first control point, the second control point, and the third control point, construct the first, second, and third layout holes.
[0048] The use of the first, second, and third surveying holes makes total station surveying easier and improves the accuracy of axis division.
[0049] See Figure 5 and Figure 6 , Figure 5 This shows a flowchart before step S130 of the present invention. Figure 6This shows a top view of the custom coordinate system used in construction according to the present invention. The present invention provides a method for measuring and setting out building floors, including the following steps before step S130:
[0050] Step S1301: Set up axes on the second floor and form a custom coordinate system by the intersection of the axes.
[0051] In particular, by setting up a standardized coordinate system, the impact of differences in human experience on measurement results is reduced, making the measurement work more reproducible and stable.
[0052] See Figure 7 The diagram shows a flowchart of step S130 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S130 includes:
[0053] Execute step S131: Set up a total station at the second survey hole and set the intersection of the longitudinal and transverse axes at the location of the second survey hole as the origin of the station coordinates.
[0054] At the second survey hole, the station coordinates (0, 0) are entered. This coordinate setting is to establish a relative measurement coordinate system to facilitate subsequent angle and distance measurements. Then, step S132 is executed.
[0055] Execute step S132: Take the connection axis between the second and first wire-laying holes as the X-axis.
[0056] Among them, taking the projection point at the first laying hole as the backsight direction, and inputting 0° on the total station for angle orientation, this step determines the starting direction of the measurement and is the key orientation link in the entire laying process. Then, step S133 is executed.
[0057] Execute step S133: Take the connection axis between the second and third wire laying holes as the Y-axis.
[0058] After the backsight operation is completed, rotate the total station and aim it at the third survey hole to project the point. During the rotation, operate slowly and smoothly to avoid errors caused by improper operation. At this time, observe the azimuth displayed on the total station screen. When the azimuth is infinitely close to 90°, it indicates that the orientation and measurement preparation work of the total station has been completed.
[0059] See Figure 8 This diagram illustrates another flow chart of step S130 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S130 further includes:
[0060] Execute step S134: Set the angle between the X-axis and the Y-axis to 90°.
[0061] The X-axis and Y-axis are the reference axes of the custom coordinate system.
[0062] See Figure 9 This diagram illustrates another flow chart of step S130 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S130 further includes:
[0063] Execute step S135: Set the X-axis direction to due north and the Y-axis direction to due east.
[0064] The X and Y axes indicate directions to facilitate positioning by comparing with architectural construction drawings.
[0065] See Figure 10 The diagram shows a flowchart of step S140 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S140 includes:
[0066] Perform step S141: Move the reflector, align the total station with the reflector and mark it, then perform step S142.
[0067] Execute step S142: Obtain the coordinates of the marked point according to the custom coordinate system.
[0068] The measurement work is carried out using the reflector mode of the total station. Move the reflector and aim the total station at the bottom of the crosshair mark on the reflector, about 1~2mm above the ground, until the Y-axis reading of the total station is 18.000m, then the mark can be made.
[0069] See Figure 11 This illustrates another flowchart of step S140 of the present invention. The present invention provides a method for measuring and setting out building floors, wherein step S140 further includes:
[0070] Execute step S143: Connect the two marked points to obtain the target axis.
[0071] In this embodiment, the total station's reflector mode is used for measurement. To lay out any axis, such as the D-axis, simply move the reflector. Aim the total station at the bottom of the crosshairs on the reflector, approximately 1-2 mm above the ground, until the Y-axis reading on the total station reaches 18.000 m. Move the reflector approximately the desired length to the left or right. Similarly, use the reflector to find a second point. Then, use the ink line to mark these two points to establish the D-axis. Likewise, the corresponding digital axis can be laid out based on the X-axis value.
