Abstract
Description
Technical Field
[0001] This invention relates to the field of construction surveying technology, and in particular to an auxiliary device and construction method for measuring and setting out an integral lifting formwork. Background Technology
[0002] In the construction of super high-rise buildings, construction surveying and control is a crucial step, directly impacting the accuracy of the building's structural plan positioning and elevation control. This effectively prevents problems such as excessive vertical misalignment, tilting, and torsion. Integrated lifting formwork, such as climbing formwork, top formwork, and steel platforms, is commonly used in the construction of super high-rise building structures. These typically integrate functional systems such as lifting systems, work scaffolding systems, structural formwork systems, safety protection systems, and work platform systems. Some also incorporate concrete pouring equipment, construction hoists, tower cranes, and other mechanical equipment. This makes the shape and working environment of the integrated lifting formwork quite complex, posing significant difficulties and challenges to high-altitude construction surveying and control. One particularly important surveying and control step is the establishment of axis control lines. These lines can be used to verify the planar deviations of the already constructed structure and, more importantly, to position the structure to be constructed.
[0003] Currently, the measurement and layout of axis control lines on the overall lifting formwork mostly follows the traditional method of marking lines on each floor with ink. The process is as follows:
[0004] S1' Selecting the reference point location: In the early stage of the overall lifting mold design and processing, select a suitable axis control reference point for reference point location.
[0005] S2' Reserved measuring hole: When designing and processing the overall lifting mold frame, reserve a measuring hole that runs through the top and bottom according to the selected measurement position.
[0006] S3' Install laser receiving target: Fix a semi-transparent laser receiving target in the measuring hole at the top of the overall lifting mold frame.
[0007] S4', Measurement axis control reference point: From the reference point below the overall lifting mold, use a plumb line to vertically project the laser beam to the corresponding laser target on the overall lifting mold, and mark the receiving light point on the laser target. After calibration, a temporary reference point is obtained.
[0008] S5', Transferring Control Line Marking Points to the Laser Target: Transferring the temporary reference point on the laser target to a fixed object in its vicinity. The transfer method involves using a steel ruler, tape measure, or leather tape measure to mark the point on a solid object, offsetting it by a fixed distance from the temporary reference point in a direction approximately perpendicular and parallel to the axis. The marking points can be made by welding steel nails or by using markers, colored paint, etc.
[0009] S6', Draw axis control lines: When axis control lines are needed, draw an ink line or a chalk line between two marked points on the same control line. Both ink lines and chalk lines can be used as axis control lines. Further measurement verification and positioning work will be completed using tools such as plumb bobs and tape measures.
[0010] As mentioned above, this traditional measurement and layout method has the following shortcomings:
[0011] 1) The temporary reference point obtained from the initial measurement is located on the laser target, which is a semi-transparent thin plate. The laser target is not a solid fixed object, and its temporary reference point is not convenient to be used directly to fix the control line and as the endpoint of the control line. Therefore, it is necessary to move it to the side again to make a mark or draw an ink line. However, the method of moving it to the side again is relatively rough and is prone to large deviations.
[0012] 2) The overall lifting formwork is lifted layer by layer as the structure is constructed. The axis control point marks are repeatedly erased and painted in a small area around the measuring holes. If steel nails are welded, the modification is more troublesome. If the old marks are not cleaned up in time, they are easily misused.
[0013] 3) The overall lifting formwork is subject to wind load at high altitudes, which can easily cause large deviations. To check and correct such deviations, it is necessary to repeat the measurement, marking, and drawing of control lines.
[0014] In view of the shortcomings of existing measurement and layout methods, those skilled in the art have been searching for solutions. Summary of the Invention

[0066] Accordingly, this embodiment also provides a construction method for measuring and setting out the integral lifting formwork. See below for reference. Figures 1 to 8 This embodiment describes in detail the construction method for measuring and setting out the integral lifting formwork.
[0067] First, perform step S1 to select the measurement position: In the early stage of the overall lifting mold design and processing, select a suitable axis control reference point measurement position; wherein, the axis control line formed by the axis control reference point is a closed figure and encloses most of the main structure.
[0068] Next, proceed to step S2, reserving measurement holes: When designing and processing the overall lifting mold frame, reserve measurement holes that run vertically through the selected measurement position.
[0069] Next, please refer to Figure 1 and Figure 2 Step S3 involves installing several auxiliary devices: After assembling the overall lifting formwork, select suitable measuring holes on the top surface of the overall lifting formwork (usually selected at the point obtained by offsetting the intersection of closed intersecting building axes outward by an appropriate operating distance) to install the auxiliary devices. Test each installed auxiliary device to ensure that the first and second sliding plate assemblies can slide and lock along the side of the angle steel frame 4. Specifically, the auxiliary devices are fixed by welding the angle steel columns (1, 2, 3) to the top steel beam surface of the overall lifting formwork.
[0070] Next, please refer to Figure 5Step S4 is executed to determine the reference point for axis control: at the reference point below the overall lifting mold frame, a laser beam is vertically projected onto the laser receiving target 5 of the auxiliary device using a plumb line, and the receiving light spot / spot on the laser receiving target 5 is marked. After calibration by rotation, a temporary reference point for the laser receiving target 5 is obtained. Specifically, the plumb line is rotated 90° multiple times to obtain four marks, and the centroids of the four marks are used as the temporary reference point after calibration.
[0071] Next, please refer to Figure 6 Execute step S5 to obtain the secondary reference point: Adjust the first and second sliding ruler components of the auxiliary device so that they intersect above the temporary reference point, away from the outer edge of the enclosure structure. The intersection of the two is the secondary reference point. By transferring the temporary reference point on the laser receiving target to the two sliding rulers to form the secondary reference point, a more intuitive, stable, and easy-to-use axis control reference point is obtained. Since the secondary reference point is positioned by the intersection of the two sliding rulers, it has an adjustable property, which is convenient for re-checking and adjusting if the overall lifting frame may shift after strong winds at high altitudes.
[0072] Specifically, step S5 includes the following steps:
[0073] S51. Loosen the first slide bolt group 8 and the first slide bolt 9 of the first slide assembly;
[0074] S52. Adjust the first sliding ruler assembly so that the first sliding ruler 10 is located directly above the temporary reference point of the laser receiving target 5, away from the outer edge of the enclosure structure.
[0075] S53, Loosen the second slide bolt group 13 and the second slide bolt 14 of the second slide assembly;
[0076] S54. Adjust the second sliding ruler assembly so that the second sliding ruler 15 is located directly above the temporary reference point of the laser receiving target 5, away from the outer edge of the enclosure structure.
[0077] S55. While keeping the outer edges of the first slide bar 10 and the second slide bar 15 from deviating from the temporary reference point, lock the first slide bar 10 and the second slide bar 15. The two intersect to form four intersection points. Take the intersection point of the outer edges of the first slide bar 10 and the second slide bar 15 as the secondary reference point.
[0078] Next, please refer to Figure 3 , Figure 4 and Figure 7Execute step S6, set the axis control line: Select a thin rope with a length greater than the distance between two adjacent auxiliary devices (here named the first auxiliary device and the second auxiliary device). The setting path of the thin rope is as follows: the first end of the thin rope passes through the plane where the secondary reference point is located on the first auxiliary device, wraps downwards to its lower right diagonal intersection point, and pulls it to the bolt on the first auxiliary device for winding and knotting for fixation; the second end of the thin rope is pulled to the adjacent second auxiliary device, passes through the secondary reference point on the second auxiliary device, wraps upwards from below its diagonal intersection point, and pulls it to the bolt on the second auxiliary device for winding and knotting for fixation; the remaining auxiliary devices are set with thin ropes in the same way, such as... Figure 3 As shown, the thin ropes stretched between adjacent auxiliary devices eventually form a closed shape. This device integrates the functions of receiving and measuring axis control reference points and setting up physical axis control lines. It is compact and simple in design, customizable, and easy to install on the overall lifting mold frame. Utilizing physical thin lines as axis control lines, it is not limited by irregular shapes or holes in the overall lifting mold frame, and is reusable and easy to replace. This improves upon the problems of traditional axis control line measurement and setting-out methods, where reference points are difficult to use directly and control lines are inconvenient to set up.
[0079] Next, proceed to step S7 to complete the measurement verification and positioning. Specifically, a plumb bob and measuring tape are used for measurement verification and positioning. After the measurement is completed, the string can be disassembled and stored for future use.
[0080] It should be noted that, for the sake of simplicity, the foregoing method embodiments are all described as a series of actions. However, those skilled in the art should understand that this application is not limited to the described order of actions, as some steps may be performed in other orders or simultaneously according to this application.

[0081] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.
[0082] The present invention has the following advantages:
[0083] 1) The auxiliary device can transfer the temporary reference point on the laser receiving target to the two sliding rulers to form a secondary reference point, thereby obtaining a more intuitive, stable and easy-to-use axis control reference point;
