Detailed implementation manners

[0049] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in various forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of the example embodiments to those skilled in the art. The features, structures, or characteristics described may be combined in any suitable manner in one or more embodiments.

[0050] In addition, the accompanying drawings are only schematic illustrations of the embodiments of the present disclosure and are not necessarily drawn to scale. The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities.

[0051] In this example embodiment, an assembly platform for assembling polygonal variable cross-section steel tower segments is first provided. Referring to Figure 1 as shown, the assembly platform 300 may include: a bracket 310 and an assembly table 320. Among them, the bracket 310 is vertically arranged on the ground platform 100, and the height of the bracket 310 is a preset value. The assembly table 320 is arranged on the top of the bracket 310, and the assembly table 320 has a grid structure, so that construction workers can freely enter and exit at the grid of the assembly table 320.

[0052] Through the above assembly platform 300, this method can ensure that during the internal assembly operation of all variable cross-section steel tower segments, operators can enter and exit the inside of the segments from the bottom of the assembly platform 300, with high safety.

[0053] Next, with reference to Figures 1 to 12 each part of the above-mentioned assembly platform for assembling polygonal variable cross-section steel tower segments in this example embodiment will be described in more detail.

[0054] In one embodiment, for the vertical assembly of traditional steel tower segments, it is carried out directly on the assembly body platform. First, the position lines of the segments to be assembled are marked on the leveled ground platform, and then the angle support tooling 500 is installed according to the position lines and each wall plate unit of the steel tower segment is placed. When operating inside the steel tower segment, operators need to enter and exit from the top through a ladder, which has great potential safety hazards. Assembling directly on the ground platform, there is temporary welding and fixing on the platform during segment assembly, which causes great damage to the platform. Before assembling the next segment, the workload for repairing the ground platform is large, and at the same time, it seriously affects the layout accuracy of the position lines for assembling the next segment and the control of the segment assembly quality.

[0055] In this application, an assembly platform 300 with a preset installation height is designed on the ground platform. For example, the height is 1.4 m, but specific values are not limited here. The top surface of the assembly platform 300 adopts a grid structure, which can meet the reliable support and wiring positioning of all wall panel units of each variable cross-section steel tower segment. At the same time, it can ensure that when assembling inside all variable cross-section steel tower segments, operators can enter and exit the inside of the steel tower segment from the bottom of the assembly platform 300, with high safety.

[0056] In this exemplary embodiment, a method for using an assembly platform for assembling a polygonal variable cross-section steel tower segment is also provided. As shown in Figure 2 , this method includes: step S101 to step S106.

[0057] Step S101: Model the target steel tower and divide the target steel tower into multiple segments;

[0058] Step S102: Obtain the geometric parameters of each segment, and establish a ground platform 100 and a manufacturing angle support tooling 500 according to the geometric parameters;

[0059] Step S103: Layout a basic assembly position line group 200 on the ground platform 100 according to the geometric parameters;

[0060] Step S104: Establish an assembly platform 300 on the ground platform 100, and transfer the basic assembly position line group 200 to the assembly platform 300 to layout an installation assembly position line group 400;

[0061] Step S105: Assemble the angle support tooling 500 on the assembly platform 300 according to the installation assembly position line group 400;

[0062] Step S106: Assemble each segment in sequence according to each assembly position line and the angle support tooling 500.

[0063] Through the above method for using an assembly platform for assembling a polygonal variable cross-section steel tower segment, this method is applicable to the assembly of segments of steel towers with various different cross-section sizes, and can quickly and accurately layout the assembly position lines of multiple variable cross-section steel tower segments at one time in advance, with high work efficiency and guaranteed precision control. This method can ensure that when assembling inside all variable cross-section steel tower segments, operators can enter and exit the inside of the segment from the bottom of the assembly platform 300, with high safety.

[0064] Next, each step of the above method for using an assembly platform for assembling a polygonal variable cross-section steel tower segment in this exemplary embodiment will be described in more detail with reference to Figures 2 to 12 This will be described in more detail with reference to

[0065] In step S101, a three-dimensional overall model of the target steel tower is built using BIM (Building Information Modeling), and the completed model is divided into multiple segments.

[0066] It can be understood that if there are multiple target steel towers in the model, the target steel towers are manufactured sequentially.

[0067] In step S102, the geometric parameters of each segment are accurately obtained to ensure the accuracy of the manufactured segments. And a reasonable assembly site is selected according to the geometric parameters of each segment to establish the ground platform 100, and an angle support tooling 500 matching the slope direction of the segment is manufactured.

[0068] In step S103, according to the geometric parameters of each segment, a basic assembly position line group 200 is laid out in advance on the ground platform 100, and each wall panel unit of the segment can be placed according to the basic assembly position line group 200, and then the segment can be assembled.

[0069] In step S104, an assembly platform 300 is designed first, and the assembly platform 300 is established on the ground platform 100. After the assembly platform 300 is installed, the basic assembly position line group 200 of the segment is converted to the assembly platform 300 together. There is no other operation content on the ground platform 100, and the basic assembly position line group 200 on the ground platform 100 can be permanently and accurately reserved. When each segment is assembled, the accuracy of the basic assembly position line group 200 can be ensured again by checking the assembly position lines on the assembly platform 300 and the assembly position lines on the ground platform 100.

[0070] In steps S105 and S106, the angle support tooling 500 is installed on the assembly platform 300 according to the installation assembly position line group 400, and each wall panel unit of the steel tower segment is placed in place, and then the steel tower segment can be successfully assembled.

[0071] In one embodiment, the geometric parameters include: the upper cross-section dimension data, the lower cross-section dimension data, and the slope data of the side wall of each segment.

[0072] Specifically, the upper cross-section dimension data includes the length of each side of the upper cross-section of the segment, the degree of the angle formed by every two adjacent side lengths, etc., and the lower cross-section dimension data includes the length of each side of the lower cross-section of the segment, the degree of the angle formed by every two adjacent side lengths, etc., to ensure that accurate basic assembly position line group 200 and installation assembly position line group 400 can be obtained; the slope data of the side wall includes the degree of inclination of each segment.

[0073] In one embodiment, the step of laying out the basic assembly position line group 200 on the ground platform 100 according to the geometric parameters includes: laying out a horizontal reference line 110 and a vertical reference line 120 on the ground platform 100; obtaining the assembly position data of each of the segments according to the upper cross-section dimension data, the lower cross-section dimension data, and the slope data of the side walls of each of the segments; and sequentially laying out the upper assembly position lines and the lower assembly position lines of all the segments on the ground platform 100 based on the horizontal reference line 110 and the vertical reference line 120 to form the basic assembly position line group 200.

[0074] Specifically, on the levelled ground platform 100, first draw a horizontal reference line 110 and a vertical reference line 120 for segment assembly; then obtain the assembly position data of the upper cross-section and the assembly position data of the lower cross-section of each stage according to the upper cross-section dimension data, the lower cross-section dimension data, and the slope data of the side walls of each segment; and then, based on the horizontal reference line 110 and the vertical reference line 120, lay out the upper assembly position lines and the lower assembly position lines of all the segments on the ground platform 100. The upper assembly position lines and the lower assembly position lines of all the segments form the basic assembly position line group 200.

[0075] In one embodiment, for two adjacent segments, the upper assembly position line of the lower segment coincides with the lower assembly position line of the upper segment.

[0076] Specifically, for two adjacent segments, the upper cross-section of the lower segment is the same as the lower cross-section of the upper segment. Then it can be understood that the upper assembly position line of the lower segment coincides with the lower assembly position line of the upper segment.

[0077] In one embodiment, the step of establishing the ground platform 100 and manufacturing the angle support tooling 500 according to the geometric parameters includes: determining the size of the ground platform 100 according to the lower cross-section dimension data of the bottommost segment and establishing the ground platform 100; manufacturing the corresponding angle support tooling 500 according to the slope data of the side walls.

[0078] Specifically, the size of the ground platform 100 should be larger than the lower cross-section size of the bottommost segment to have enough space to manufacture all the segments.

[0079] The inclination angles of the side walls of the target steel tower are fixed. Therefore, the same side of each stage can be supported by the same angle support tooling 500. It can be understood that the side walls in the inclination direction of the target steel tower can use the angle support tooling 500, and some side walls do not bear force, so angle support tooling 500 is not required.

[0080] In one embodiment, after the step of establishing the ground platform 100, the method further includes: performing foundation treatment and site hardening on the ground platform 100 to ensure the flatness and bearing capacity requirements of the ground platform 100.

[0081] Specifically, after performing foundation treatment and site hardening on the ground platform 100, the flatness and bearing capacity of the ground platform 100 are optimized, so that the flatness and bearing capacity of the treated ground platform 100 meet the requirements.

[0082] In this method, an assembled platform 300 with a preset installation height is designed on the ground platform. For example, the height is 1.4 m, which is not specifically limited here; the top surface of the assembled platform 300 adopts a grid structure, which can meet the reliable support and wiring positioning of all wall panel units of each variable cross-section steel tower segment. At the same time, it can ensure that when assembling inside all variable cross-section steel tower segments, operators can enter and exit the inside of the steel tower segment from the bottom of the assembled platform 300, with high safety.

[0083] In one embodiment, the step of converting the basic assembly position line group 200 to the assembled platform 300 and laying out the installation assembly position line group 400 includes: using the plumb line method to convert the assembly position line group on the ground platform 100 to the assembled platform 300 and laying out the installation assembly position line group 400.

[0084] Specifically, by using the plumb line method to convert and lay out the assembly position line group on the ground platform 100 to the assembled platform 300, the accuracy of the installation assembly position line group 400 on the assembled platform 300 can be ensured.

[0085] In one embodiment, the flatness of the top surface of the assembled platform 300 ≤ 1 mm / full section, and the elevation of the top surface of the assembled platform 300 ≤ 0.5 mm. Specifically, the flatness of the top surface of the assembled platform 300 can be 0.5 mm / full section, 0.8 mm / full section; the elevation of the top surface of the assembled platform 300 can be 0.5 mm, 0.3 mm.

[0086] In one embodiment, the accuracy of the assembly wiring of the segment (i.e., the deviation of the assembly position line) ≤ 0.5 mm. Specifically, the accuracy of the assembly wiring of the segment can be 0.5 mm, 0.3 mm.

[0087] In a specific embodiment, each segment of the complex octagonal variable cross-section steel tower is manufactured. The specific scheme is as follows:

[0088] As Figure 3 shown, the octagonal variable cross-section steel tower is modeled using BIM three-dimensional integration, and the model of the octagonal variable cross-section steel tower is divided into multiple segments.

[0089] As Figure 4 shown, according to the structural form and geometric dimensions of the steel tower assembly segment, the basic assembly position line group 200 of the octagonal variable cross-section steel tower is obtained through analysis.

[0090] As Figure 5 shown, a reasonable ground platform 100 is selected.

[0091] As Figure 6 、 Figure 7 shown, first, on the ground platform 100, the transverse reference line 110 and the longitudinal reference line 120 for segment assembly are marked as the reference lines for laying out the assembly positions of each variable cross-section steel tower segment. Then, according to the transverse reference line 110 and the longitudinal reference line 120, the assembly position lines of each segment to be assembled are laid out in advance on the ground platform.

[0092] As Figure 8 shown, an assembly platform 300 with an installation height of 1.4 m is designed and installed on the ground platform 100. The top surface of the assembly platform 300 adopts a grid structure, which can meet the reliable support and wiring positioning of all wall panel units of each variable cross-section steel tower segment.

[0093] As Figure 9 shown, before the assembly of the steel tower segment, the assembly position line of the segment on the ground platform 100 is transformed and laid out on the top surface of the assembly platform 300 by the plumb line method. Then, according to the spatial inclination angle of the steel tower segment, the angle support tooling 500 is installed along the assembly position line of the segment, and each wall panel unit of the steel tower segment is placed in position. The internal operators of the steel tower segment can enter and exit the steel tower from the bottom of the assembly platform 300.

[0094] As Figure 10 shown, along the installation assembly position line group 400, each wall panel unit of the assembly segment is placed in position to complete the segment assembly.

[0095] In addition, when a segment is assembled and removed from the platform, before assembling the next segment, only the assembly position line to be assembled on the assembly platform 300 and the assembly position line on the ground platform need to be rechecked by the plumb line method again. After the recheck is correct, each wall panel unit of the steel tower segment can be directly placed in position. At the same time, the used assembly angle support tooling 500 and its position remain fixed all the time, and the assembly support tooling does not need to be repeatedly installed and removed according to different assembled segments.

[0096] Among them, as Figure 11 shown, it is the plan view of the multi-segment vertical assembly wiring platform of the octagonal variable cross-section steel tower; as Figure 12 shown, it is the schematic diagram of a single segment of the octagonal variable cross-section steel tower.

[0097] Through the above-mentioned assembly platform 300 and its usage method, it is applicable to the assembly of steel tower segments with various different cross-sectional dimensions, and can quickly and accurately lay out the assembly position lines of multiple variable cross-section steel tower segments at one time in advance, with high efficiency and guaranteed precision control. By laying out all the assembly position lines of the steel towers to be assembled on the ground platform 100 in advance, they can be transferred to the top surface of the assembly platform 300 together after the installation of the assembly platform 300 is completed. There is no other operation content on the ground platform 100, and the assembly position lines on the ground platform 100 can be permanently and accurately retained. When assembling each segment, the accuracy of the assembly position line of the steel tower segment can be ensured again by checking the assembly position line on the assembly platform 300 and the assembly position line on the ground platform 100. According to the assembly position lines of the multi-segment steel tower, the assembly support tooling for the segments can be designed in advance, and the assembly support tooling and positions of the multi-segment steel tower can be shared, reducing repeated installation and removal. It can ensure that when all the internal assembly operations of the variable cross-section steel tower segments are carried out, the operators can enter and exit the interior of the steel tower segments from the bottom of the assembly platform 300, with high safety. After adopting this assembly wiring platform and wiring method, the assembly efficiency of the steel tower segments can be increased by 40%, and the cost can be saved by 30%.
