Description

Technical Field

[0001] The present application relates to the field of curtain wall structure construction, and in particular to a method for assembling a hyperbolic aluminum plate curtain wall panel structure. Background Art

[0002] The main structure of the hyperbolic aluminum panel curtain wall system is mainly composed of panel frames. Due to the large size of the panel frames, they need to be disassembled into several frame units during actual construction, which are then manufactured separately and then assembled into a complete structure.

[0003] like Figure 1 The frame unit 1 of the panel frame is composed of a plurality of chords 11 and webs 12 , wherein the chords 11 are spliced ​​by a plurality of rods 111 , and the webs 12 are tension-welded between adjacent chords 11 .

[0004] During the current frame unit production process, relevant construction workers generally use the two-dimensional line-laying method to perform the frame unit welding operation. However, this operation method has obvious disadvantages. During the actual production process, due to the combined influence of various factors such as construction workers' operating errors and welding deformation, the overall production accuracy of the actual frame units is poor, and cumulative errors are prone to occur. In the subsequent splicing of the frame units, adjacent frame units are prone to mismatching, gaps that are too large or too small, and inability to fit tightly. This greatly increases the workload of on-site adjustment and repair, prolongs the construction period, and may also cause the structural strength of the connections between adjacent frame units to decrease, thereby affecting the overall stability and safety of the entire hyperbolic aluminum curtain wall panel structure. It may even cause the aluminum plates of the special-shaped curved aluminum curtain wall to deviate during installation. Therefore, there is room for improvement. Summary of the Invention

[0005] In order to better improve the manufacturing accuracy of the roof panel frame unit, the present application provides a method for assembling a hyperbolic aluminum curtain wall panel structure.

[0006] This application provides a method for assembling a hyperbolic aluminum curtain wall panel structure, which adopts the following technical solutions: A method for assembling a hyperbolic aluminum curtain wall panel structure comprises the following steps: S1: Obtaining the position of the positioning points: Establishing a three-dimensional model of the frame unit, determining several positioning points on the members of the frame unit model, and obtaining the three-dimensional coordinate data of the positioning points; S2: Surveying and setting out: The total station uses the three-dimensional coordinate data of the positioning points to lay out the positioning axis of the tire frame on the ground; S3: Tire frame support: Tire frames are supported at various positioning axes to support and position the rods of the chord; S4: Chord assembly: Move the rods to the frame according to the hoisting method, and weld the adjacent ends of the adjacent rods to form the chord; S5: Web member assembly: hoist and move the web members between adjacent chord members in sequence, and weld and fix the two ends of the web members to the adjacent chord members respectively.

[0007] By adopting the above technical solution, the three-dimensional coordinate data of the chord positioning point is determined using the three-dimensional model, and then the total station is used to mark the points using the three-dimensional coordinates of the positioning points, and a tire frame is set up to support and position the chord members. Subsequently, the chord is assembled and welded on the tire frame, and the tire frame is used to support and position the various members of the chord to achieve precise welding between adjacent members of the chord. Compared with traditional operation methods, this is conducive to reducing the poor manufacturing accuracy of the frame unit due to welding deformation and operational errors of construction personnel, and effectively improves the overall manufacturing accuracy of the frame unit.

[0008] Preferably, the tire frame includes a support rod, a positioning support portion is provided on the top of the support rod, the positioning support portion includes a positioning rod, the positioning rod is vertically connected to two limiting rods, and the positioning rod and the two limiting rods form a limiting groove for the rod to be embedded; In step S4, when assembling the chord rod, the rod is placed into the limiting groove of the positioning support part at the top of the tire frame.

[0009] By adopting the above technical solution, a positioning support part is set on the top of the support rod of the tire frame, and the positioning support part is formed by the positioning rod and two limiting rods to form a limiting groove. When the chord rod is actually assembled, the rod can be placed in the limiting groove, and the limiting groove is used to perform embedded positioning on the rod of the chord rod, which effectively avoids the position deviation of the rod part, and is conducive to improving the overall assembly accuracy of the chord rod.

[0010] Preferably, both of the limiting rods are threaded with limiting bolts, and the limiting bolts of the two limiting rods are arranged opposite to each other; In step S4, after the rod is placed into the limiting groove located at the tire frame positioning support portion, the limiting bolts at the two limiting rods are screwed until the two limiting bolts are tightly against the rod.

[0011] By adopting the above technical solution, some chords have a certain curvature due to design requirements, and need to be placed at an angle during the assembly process, which can easily cause the rods to move in the limit grooves; by arranging limit bolts on the two limit rods, when the rods are subsequently placed in the limit grooves, the limit bolts on the two limit rods can be used to limit the rods in the limit grooves, thereby limiting the displacement of the rods during the splicing process, which is conducive to better supporting and positioning the rods through the positioning support part.

[0012] Preferably, an adjusting sleeve is provided on the top of the support rod, the adjusting sleeve is threadedly sleeved on the top of the support rod through a threaded structure, and the positioning rod is vertically rotatably connected to the top of the adjusting sleeve; In step S4, after the tire frame is set up, the total station uses the three-dimensional coordinate data of the chord positioning point to mark the point, and rotates the adjustment sleeve to adjust the positioning support plate on the top of the tire frame to the chord positioning point, and at the same time rotates the positioning rod to correct the direction of the positioning support part.

[0013] By adopting the above technical solution, the adjusting sleeve is threadedly connected to the top of the support rod, and the height of the positioning support part can be adjusted by rotating the adjusting sleeve, which is convenient for better adjusting the positioning support part into place in combination with the total station marking during the tire frame support process; by rotating the positioning rod connected to the top of the adjusting sleeve, after subsequently adjusting the positioning support part into place by rotating the adjusting sleeve, the positioning rod can be rotated to correct the direction of the positioning support part, thereby avoiding the situation where the direction of the positioning support part is offset due to the rotation of the adjusting sleeve.

[0014] Preferably, a support shaft is vertically connected to the bottom of the positioning rod, a connection hole is opened at the top of the adjusting sleeve, the support shaft is rotatably inserted into the connection hole, a fastening bolt is threaded through the outer circumference of the adjusting sleeve, and one end of the fastening bolt extends into the connection hole; In step S4 , after rotating the positioning rod to correct the orientation of the positioning support portion, the fastening bolt is screwed until the fastening bolt is tightly abutted against the support shaft.

[0015] By adopting the above technical solution and adjusting the setting of the fastening bolts on the outer periphery of the sleeve, during the actual construction process, after completing the orientation correction of the positioning support part, the support shaft can be limited by the fastening bolts to limit the swing of the positioning support part and reduce the situation where the orientation of the positioning support part is offset again due to external loads or accidental touch by the operator.

[0016] Preferably, in step S4, spot welding is first performed on the adjacent ends of the adjacent rods, and then the positions of the rods are verified by a total station. After the verification is correct, full welding is performed on the adjacent ends of the adjacent rods.

[0017] By adopting this technical solution, the adjacent rods are initially connected by spot welding at their adjacent ends, preventing them from shifting during subsequent operations. The rod positions are then verified using a total station to ensure that their actual positions are consistent with the design requirements, further improving the accuracy of the frame unit assembly.

[0018] Preferably, the bottom of the support rod is vertically connected to a bottom plate, and the bottom plate is provided with a plurality of through holes; In step S3, after the tire frame is set in place, anchor bolts are inserted through the through holes of the bottom plate and driven into the ground.

[0019] By adopting the above technical solution, the subsequent welding and fabrication of the frame units will generate a large external load on the tire frame. By inserting anchor bolts through the through-holes of the base plate and driving them into the ground, the tire frame is firmly supported and fixed at the corresponding positioning points, effectively preventing the tire frame from shifting due to external loads during construction, resulting in deviation from the positioning points.

[0020] Preferably, in step S3, after the bottom plate of the tire frame is fixed to the ground by anchor bolts, connecting rods are installed between adjacent tire frames.

[0021] By adopting the above technical solution, by further supporting and installing connecting rods between adjacent tire frames, and using the connecting rods to connect and limit the adjacent tire frames, a mutually supporting structural system can be formed between the tire frames, thereby significantly enhancing the ability of the tire frames to resist external loads and vibrations during construction, further reducing the displacement or tilt of the tire frames during use, and ensuring the position accuracy of the chord rods during assembly.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The positioning points on the chord and their 3D coordinate data are determined through the 3D model, and the points are marked and the cradle is set up with the help of a total station. The cradle is used to provide stable support and precise positioning for the chord members, ensuring the position accuracy of adjacent members during welding. At the same time, during the assembly of the web members, the cradle can keep the adjacent chord members in the correct position, thereby ensuring the precise connection between the web members and the chord members, and effectively improving the manufacturing accuracy of the frame unit.

[0023] 2. The design of the threaded connection between the adjusting sleeve and the support rod, combined with the marking of the total station, can flexibly adjust the height of the positioning support part to the chord positioning point, ensuring the accuracy of the chord assembly. At the same time, the positioning rod is rotatably connected to the top of the adjusting sleeve through the support shaft, so that after rotating the adjusting sleeve to adjust the height of the positioning support part, the direction of the positioning support part can be further corrected to avoid the situation where the positioning support part is deviated from the correct position due to the rotation of the adjusting sleeve.

[0024] 3. The setting of the limit groove of the positioning support part and the limit bolts on the two limit rods. After the chord rod is embedded in the limit groove, the rod is fixed by tightening the limit bolts to limit its displacement, thereby further improving the stability and accuracy of the rod assembly and welding process.

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] The present application discloses a method for assembling a hyperbolic aluminum curtain wall panel structure, comprising the following steps: S1: Positioning point acquisition: reference Figure 1 , the specific steps are as follows: S1.1: Create a 3D model of the frame unit 1 using 3D software: S1.2: The chord members 11 of the frame unit 1 model are divided into a number of rods 111 according to construction requirements. Positioning points are determined on the rods 111, and the three-dimensional coordinate data of each positioning point is extracted.

[0034] S2: Measurement and layout: reference Figure 1 and Figure 2 , the total station uses the three-dimensional coordinate data of the positioning point to release the positioning axis of the tire frame 2 on the ground; S3: Tire frame 2 support: refer to Figure 2 A tire frame 2 is provided at each positioning axis, and the tire frame 2 is used to support and position the rod 111 of the chord 11.

[0035] Reference Figures 3 and 4Specifically, the tire frame 2 includes a support rod 21 and a positioning support portion 22. The support rod 21 is made of high-strength steel pipe. A base plate 23 is vertically welded to the bottom end of the support rod 21. Through holes 231 are formed at the four corners of the base plate 23 for inserting anchor bolts. An adjustment sleeve 24 is coaxially supported at the top end of the support rod 21 and is coaxially threaded onto the support rod 21 via a threaded structure.

[0036] The positioning support portion 22 is located at the top of the adjustment sleeve 24. The positioning support portion 22 includes a positioning rod 221 and two limiting rods 222. The two limiting rods 222 are vertically supported on the positioning rod 221. The positioning rod 221 and the two limiting rods 222 cooperate to form a limiting groove for the rod 111 to be inserted. Subsequently, the rod 111 of the chord member 11 is placed into the limiting groove formed by the positioning rod 221 and the two limiting rods 222 to support and position the rod 111.

[0037] The two limiting rods 222 are both threaded with limiting bolts 2221, and the limiting bolts 2221 of the two limiting rods 222 are arranged opposite each other. After the chord member 11 is placed in the limiting groove, the limiting bolts 2221 on the two limiting rods 222 can be tightened until the limiting bolts 2221 on the two limiting rods 222 are tightly abutted against the rod 111 located in the limiting groove, thereby further limiting the position of the rod 111 and preventing displacement of the rod 111.

[0038] The bottom end of the limiting rod 222 is welded with a connecting pipe 2222, and the connecting pipe 2222 is sleeved on the positioning rod 221. The outer peripheral side of the connecting pipe 2222 is threaded with a fixing bolt 2223. One end of the fixing bolt 2223 extends to the inner cavity of the connecting pipe 2222 and presses against the positioning rod 221 to limit the limiting rod 222 from sliding along the positioning rod 221 through the connecting pipe 2222. Through the above arrangement, the relative positions of the two limiting rods 222 can be adjusted, which is convenient for adjustment according to the size of the rod 111. The gap between the two limiting rods 222 makes it easier for the subsequent rod 111 to be inserted into the limiting groove of the positioning support part 22.

[0039] The adjustment sleeve 24 is coaxially threaded onto the top of the support rod 21 via a threaded structure; a connecting hole 240 is coaxially defined at the top of the adjustment sleeve 24. A support shaft 223 is vertically connected to the positioning rod 221, forming a T-shape with the positioning rod 221. The support shaft 223 coaxially rotates and engages the connecting hole 240 at the top of the adjustment sleeve 24. The configuration of the adjustment sleeve 24 allows for stepless adjustment of the ground positioning support 22 by rotating the adjustment sleeve 24. The positioning support 22 on the tire frame 2 can then be moved to a desired position based on construction needs, allowing the tire frame 2 to adapt to different chord 11 positioning points, thereby improving assembly flexibility and precision. By rotating the positioning rod 221 and connecting it to the top of the adjusting sleeve 24 through the support shaft 223, the positioning support part 22 can be moved into position by rotating the adjusting sleeve 24. The positioning support part 22 can be swung to correct its direction, thereby avoiding the situation where the positioning support part 22 is offset due to the rotation of the adjusting sleeve 24.

[0040] A fastening bolt 241 is threaded through the outer periphery of the top end of the adjusting sleeve 24, and the fastening bolt 241 extends to the inner cavity of the connecting hole 240 and abuts against the outer periphery of the support shaft 223; after the positioning support part 22 is subsequently swung to correct the orientation of the positioning support part 22, the support shaft 223 can be limited and fixed by the fastening bolt 241 to limit the rotation of the positioning support part 22, thereby reducing the situation where the orientation of the positioning support part 22 deviates again due to accidental touch by the operator or external load.

[0041] Reference Figures 2 to 4 , the specific steps of step S3 are as follows: S3.1: Tire carrier 2 is positioned: Move the tire carrier 2 to the positioning axis; S3.2: Secure the tire frame 2: Verify the position of the tire frame 2 using the three-dimensional coordinate data of the positioning points using a total station. Once the position of the tire frame 2 is verified to be correct, insert anchor bolts into the through holes 231 of the bottom plate 23 of the tire frame 2 and drive the anchor bolts into the ground. Secure the tire frame 2 using the anchor bolts to prevent displacement of the tire frame 2 due to external loads or operator error. S3.3: Positioning support 22 in place: The total station uses the three-dimensional coordinate data of the chord 11 positioning point to mark the point, and the adjusting sleeve 24 is rotated to adjust the positioning support plate on the top of the tire frame 2 into place. S3.4: Rotate the positioning rod 221 to adjust the orientation of the positioning support 22. After the orientation of the positioning support 22 is adjusted, tighten the fastening bolt 241 on the outer periphery of the adjustment sleeve 24 until the fastening bolt 241 is tightly abutted against the outer periphery of the support shaft 223 to restrict the rotation of the positioning support 22. S3.5: Connecting rods 25 are installed on the support rods 21 of adjacent tire frames 2. The connecting rods 25 are fastened to the support rods 21 of the tire frames 2 using fasteners. The connecting rods 25 are used to improve the connection integrity between the tire frames 2.

[0042] S4: Chord 11 assembly: refer to Figure 4 and Figure 5 , move each rod 111 to the tire frame 2 by hoisting, and weld the adjacent ends of adjacent rods 111 to form the chord 11; the specific steps are as follows: S4.1: Positioning the rods 111: Insert the chord rods 11 into the corresponding limiting grooves of the positioning support portions 22 of the tire frame 2; and butt adjacent ends of adjacent rods 111 together; S4.2: Limiting the rod 111: Rotate the limiting bolts 2221 at the two limiting rods 222 of the positioning support 22 until the limiting bolts 2221 press against the rod 111 in the limiting groove; S4.3: Temporary fixation of rods 111: Spot welding the adjacent ends of adjacent rods 111; S4.4: Fixing of rod 111: Verify the position of rod 111 using a total station. Once the position of rod 111 is verified to be correct, perform full welding on the adjacent ends of adjacent rods 111. S4.5: Repeat steps S4.1 to S4.4 until the remaining rods 111 are spliced.

[0043] S5: Assembly of belly bar 12: refer to Figure 5 and Figure 6 , hoist the web members 12 in sequence and move them between the adjacent chord members 11, and weld and fix the two ends of the web members 12 to the adjacent chord members 11 respectively. The specific steps are as follows: S5.1: Positioning the web member 12: Move the web member 12 between adjacent rods 111 and align both ends of the web member 12 with adjacent web members 12; S5.2: Temporary fixation of member 111: Spot weld the joint between web member 12 and chord member 11; S5.3: Fixing of member 111: Verify the position of web member 12 using a total station. Once the position of member 111 is verified to be correct, perform full welding on the adjacent end of adjacent member 111. S5.4: Repeat steps S5.1 to S5.3 until the remaining web members 12 are spliced.

[0044] The present application first obtains the three-dimensional coordinate data of each positioning point of the chord 11 of the frame unit 1 through a three-dimensional model, and uses a total station to mark the three-dimensional coordinate data of the positioning points, and supports a tire frame 2, and uses the tire frame 2 to support and limit the various rods 111 of the chord 11. At the same time, during the welding process of the various rods 111 of the chord 11 and the web 12, the position is verified in real time by the total station, which is beneficial to improve the position accuracy of each rod 111 of the chord 11 of the frame unit 1 during welding, and thus facilitates to better improve the overall manufacturing accuracy of the frame unit 1.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
