Description

Technical Field

[0001] This invention relates to the field of curtain wall construction technology, and specifically to a method for constructing a honeycomb aluminum panel curtain wall. Background Technology

[0002] With the continuous development of the economy and society, the number of buildings with large curtain wall structures is constantly increasing. Nowadays, the exterior decoration and embellishment of curtain walls, especially their decorative styles, are receiving increasing attention.

[0003] Existing honeycomb aluminum panel curtain wall structures, such as Figure 1 As shown, the structure includes purlin 2, upper ear plate 7, and lower ear plate 8. Purlin 2 is fixedly connected to the steel frame, and lower ear plate 8 is fixedly connected to the top of purlin 2. Upper ear plate 7 is connected to lower ear plate 8 by connecting bolt 9 and connecting bolt 10. Angle steel 30 is fixedly connected to upper ear plate 7, and honeycomb aluminum plate 4 is fixedly connected to the top of angle steel 30. This technical solution enables the adjustment of the angle of honeycomb aluminum plate 4. Specifically, when adjusting the angle, firstly, connecting bolt 9 is inserted into upper ear plate 7 and lower ear plate 8, but not locked. The angle of honeycomb aluminum plate 4 is adjusted. After the angle is adjusted, connecting bolt 9 is locked. At the same time, upper ear plate 7 and lower ear plate 8 are fixed again by connecting bolt 10.

[0004] However, while this technical solution allows for angle adjustment of the honeycomb aluminum panel, it presents several problems in severe weather conditions (such as strong winds and heavy rain). The strong winds from such storms can subject the connecting bolts between the upper and lower ear plates to continuous vibration and shearing forces. Over time, these bolts may loosen, weakening the connection between the upper and lower ear plates. If the bolts are severely loose, the upper ear plate may wobble, affecting the stability of the honeycomb aluminum panel. Furthermore, extreme wind and rain impacts can exert significant pressure on the upper ear plate, causing deformation. If the material of the upper ear plate is not strong enough or its design strength is insufficient, it may bend or twist under strong winds. A deformed upper ear plate may fail to properly secure the honeycomb aluminum panel or even damage it. In addition, this technical solution cannot accurately position the purlins at their installation location and height. Summary of the Invention

[0005] The present invention aims to provide a construction method for honeycomb aluminum panel curtain walls, so as to improve the stability of the upper ear panel, prevent the upper ear panel from deforming, and at the same time, accurately position the purlins at their installation location and height.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a construction method for honeycomb aluminum panel curtain walls, comprising the following steps: S1: Installation and construction preparation of the steel frame; S2: Purlin positioning and installation: A support unit is provided between the steel frame and the purlin. The purlin can be fixed to the steel frame through the support unit. The height of the support unit can be adjusted. The steel frame is equipped with a positioning mechanism, which can position the support unit. S3: Installation and Angle Correction of Honeycomb Aluminum Panels: Several installation units are set on the purlins, and the positioning mechanism can also position the installation units. Each installation unit consists of two installation parts, each of which includes an upper ear plate, a lower ear plate, and a No. 1 connecting bolt. The lower ear plate is fixedly connected to the top of the purlin, and the upper ear plate is connected to the lower ear plate by the No. 1 connecting bolt. The honeycomb aluminum panel is fixedly connected to the top of the upper ear plate. The angle of the honeycomb aluminum panel is adjusted. After the angle adjustment is completed, the upper ear plate is positioned by the positioning mechanism.

[0007] The beneficial effects of this solution are as follows: Due to the positioning mechanism, the installation position and height of the support unit can be accurately positioned during installation, thus ensuring the installation accuracy of the purlins. Simultaneously, after the angle of the honeycomb aluminum panel is adjusted, the positioning mechanism can effectively position the upper ear plate, greatly improving its stability and preventing deformation. In severe weather (such as strong winds and heavy rain), the positioning mechanism ensures the upper ear plate remains firmly in its fixed position, preventing movement due to external forces (such as wind or slight vibrations). This allows the honeycomb aluminum panel to be stably fixed at the required angle, enhancing the overall structural stability. When extreme wind and rain impact the honeycomb aluminum panel, they exert enormous pressure on the upper ear plate. However, due to the positioning mechanism, the upper ear plate can transfer this pressure to the positioning mechanism, which then transmits it to the purlins. This disperses the pressure on the upper ear plate over a wider area, effectively preventing deformation due to stress concentration.

[0008] The positioning mechanism in this technical solution can position both the support unit and the upper ear plate. Positioning the support unit accurately determines the installation position and height of the purlins, ensuring the stability of the connection between the steel frame and the purlins. Positioning the upper ear plate further enhances the installation stability of the honeycomb aluminum panel, especially under adverse weather conditions, effectively preventing deformation or loosening of the upper ear plate due to external forces. In conclusion, this positioning mechanism has significant application value and broad development prospects in large-scale curtain wall structures.

[0009] Preferably, the support unit includes a support adapter pipe, which is fixedly connected to the top of the steel frame. The upper end of the support adapter pipe is threaded with a support pipe, and the purlin is fixedly connected to the top of the support pipe.

[0010] The beneficial effects of this solution are as follows: because the support adapter pipe is threadedly connected to the support pipe, the height of the support pipe can be adjusted, thus further realizing the adjustment of the purlin installation height.

[0011] Preferably, the positioning mechanism includes a first positioning unit and a second positioning unit, wherein the first positioning unit is used to position the support unit and the second positioning unit is used to position the installation unit.

[0012] Preferably, the first positioning unit includes a positioning rod, which is fixed on the steel frame and its height is equal to the installation height of the support unit. A positioning screw is rotatably connected to the support adapter pipe. The positioning screw includes a smooth section, a threaded section, a limiting section and a positioning section connected in sequence. The limiting section rotates and is engaged with the support adapter pipe. The positioning section is located inside the support adapter pipe and is used to position the support adapter pipe.

[0013] The beneficial effects of this solution are as follows: Due to the setting of the first positioning unit, this technical solution can keep the support adapter pipe and the first positioning rod coaxial, thereby improving the positioning accuracy. When positioning the support adapter pipe, first put the support adapter pipe on the first positioning rod, adjust the position of the support adapter pipe so that the spherical surface of the positioning section contacts the spherical groove on the first positioning rod, and the positioning of the support adapter pipe can be achieved. Then, fix the support adapter pipe on the steel frame.

[0014] The first positioning rod is welded to the steel frame, and its height is equal to the installation height of the support unit. This allows for preliminary positioning of the support unit's installation location and provides an accurate reference for the installation height. This makes the installation of the support unit more precise, ensuring the stability and accuracy of the entire structure.

[0015] Preferably, the second positioning unit includes a slider, which is threadedly connected to the threaded section to form a lead screw pair. A guide rod is fixedly connected to the support adapter pipe, and the slider is slidably mounted on the guide rod. A push rod is detachably connected to the top of the slider. A positioning block is slidably mounted on the purlin. A second positioning rod is fixedly connected to the inclined surface of the positioning block near the upper ear plate. A first positioning hole is provided on the inclined surface of the upper ear plate near the positioning block. The second positioning rod can be inserted into the first positioning hole, and the push rod can push the positioning block to move and position the upper ear plate.

[0016] The beneficial effects of this solution are as follows: Due to the setting of the positioning block, the installation angle of the honeycomb aluminum panel can be detected. When the honeycomb aluminum panel deviates, there will be a gap at the contact position between the positioning block and the honeycomb aluminum panel. Therefore, it is possible to intuitively judge whether the installation angle of the honeycomb aluminum panel meets the requirements.

[0017] In severe weather conditions (such as strong winds and heavy rain), this design prevents the connection between the upper and lower ear plates from loosening, thus improving the stability of the honeycomb aluminum panel. After the angle of the honeycomb aluminum panel is adjusted, rotating the positioning screw will cause the slider to move horizontally towards the side closer to the upper ear plate. This, in turn, will cause the push rod to push the positioning block towards the side closer to the upper ear plate, allowing the second positioning rod to be inserted into the first positioning hole. The inclined surface of the positioning block near the upper ear plate will then contact the upper ear plate, thus accurately positioning the upper ear plate.

[0018] Preferably, the end of the positioning section near the first positioning rod is a spherical surface, and the first positioning rod has a corresponding spherical groove, allowing the spherical surface to rotate within the spherical groove.

[0019] The beneficial effects of this solution are as follows: due to the design of the spherical surface and spherical groove, the positioning screw can rotate smoothly, which facilitates the positioning of the upper ear plate. At the same time, it can reduce the wear of the No. 1 positioning rod and the positioning screw.

[0020] Preferably, S1.1: 3DMAX software is used to model the steel frame, the spatial coordinates of the steel frame are determined according to the modeling parameters, and the steel frame is installed; S1.2: Erect steel pipe scaffolding; S1.3: Use BIM technology to model the steel frame and pre-assemble it. Number the upper and lower ear plates and honeycomb aluminum panels at each connection point to ensure that factory prefabrication and on-site construction are carried out simultaneously.

[0021] The beneficial effects of this solution are as follows: This technical solution uses 3DMAX software for modeling, which can accurately determine the spatial coordinates of the steel frame, thereby improving the installation accuracy of the steel frame.

[0022] This technical solution uses BIM technology to model and pre-assemble the steel frame, which can extract parameters of components such as upper ear plates, lower ear plates, and honeycomb aluminum panels, facilitating factory prefabrication and on-site installation and improving construction efficiency.

[0023] Preferably, the positioning and installation of the purlins in S2 includes the following steps: S2.1: Positioning and installation of the support unit; S2.1.1: The positioning of the support transfer pipe is achieved by using a total station to locate the spatial position and top elevation of the support unit, using the No. 1 positioning rod as a positioning stake to fix it on the steel frame, and then using the first positioning unit and the No. 1 positioning rod to position the support transfer pipe. S2.1.2: Securely connect the support adapter pipe to the steel frame; S2.1.3: Adjust the height of the support tube to the top elevation of the first positioning rod; S2.1.4: Setting of reinforcing ribs on the support unit; S2.2: Purlin hoisting; S2.3: Purlin positioning; S2.4: Purlin installation.

[0024] The beneficial effects of this solution are as follows: This technical solution can locate the spatial position and top elevation of the support unit using a total station, and pre-fix a No. 1 positioning rod on the steel frame to determine the installation position of the support unit. Then, by cooperating with the first positioning unit through the No. 1 positioning rod, the support adapter pipe and the No. 1 positioning rod are ensured to be coaxial, thereby improving the installation accuracy of the purlin.

[0025] Preferably, an angle steel is fixedly connected to the upper ear plate, and the honeycomb aluminum plate is fixedly connected to the angle steel.

[0026] Preferably, the inclined surface of the positioning block near the upper ear plate is a stepped surface, and the inclined surface of the upper ear plate near the positioning block is also a stepped surface. The stepped surface on the positioning block is adapted to the stepped surface on the upper ear plate. A No. 3 positioning rod is fixedly connected to the stepped surface of the positioning block, and a No. 2 positioning hole is provided on the stepped surface of the upper ear plate. The No. 3 positioning rod can be inserted into the No. 2 positioning hole.

[0027] The beneficial effects of this solution are as follows: By setting stepped surfaces on the positioning block and the upper ear plate, on the one hand, the stepped surface design makes the contact between the positioning block and the upper ear plate tighter and more stable. In severe weather conditions, such as strong winds and heavy rain, the honeycomb aluminum panel will be subjected to strong wind forces. The mutual fit of the stepped surfaces can increase the friction and resistance between the upper ear plate and the positioning block, effectively resisting the pushing and torsional effects of wind on the upper ear plate. This design makes the entire structure more robust in strong wind environments, reducing swaying and displacement caused by wind, and improving the wind resistance of the honeycomb aluminum panel. At the same time, the stepped surface can better withstand forces from different directions, reducing the risk of deformation and damage caused by stress concentration. On the other hand, when the installation angle of the honeycomb aluminum panel does not meet the requirements, there will be a mismatch between the stepped surfaces on the positioning block and the stepped surfaces on the upper ear plate. Therefore, it can be used to check whether the installation angle of the honeycomb aluminum panel meets the requirements.

[0028] This technical solution, due to the setting of positioning rod No. 3 and positioning hole No. 2, can connect the upper ear plate and positioning block into a whole, thereby further improving the stability of the upper ear plate. Attached Figure Description

Detailed Implementation

[0030] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings of the instruction manual include: steel frame 1, purlin 2, connecting pipe 3, honeycomb aluminum plate 4, support adapter pipe 5, support pipe 6, upper ear plate 7, lower ear plate 8, No. 1 connecting bolt 9, No. 2 connecting bolt 10, No. 1 round hole 11, No. 1 arc-shaped hole 12, No. 2 round hole 13, No. 2 arc-shaped hole 14, No. 1 positioning rod 15, gripper 16, connecting rod 17, connecting seat 18, positioning screw 19, smooth section 20, threaded section 21, limiting section 22, positioning section 23, slider 24, positioning block 25, guide rod 26, push rod 27, strip hole 28, connecting block 29, angle steel 30, reinforcing rib 31.

[0031] Example 1 The basic structure of honeycomb aluminum panel curtain walls is as follows: Figure 1-7 As shown.

[0032] like Figure 2 The honeycomb aluminum panel curtain wall shown includes a steel frame 1, purlins 2, and a positioning mechanism. Several purlins 2 are provided, and each purlin 2 has three support units between it and the steel frame 1. The purlins 2 are fixed to the steel frame 1 through the support units. Connecting pipes 3 are welded between adjacent purlins 2. Each purlin 2 has three mounting units at its top, and honeycomb aluminum panels 4 are mounted on these mounting units. The mounting units can adjust the installation angle of the honeycomb aluminum panels 4, and the positioning mechanism can position the support units and mounting units. It should be noted that... Figure 1 The image shown is only a partial view of the honeycomb aluminum panel 4-panel curtain wall, intended for illustrative purposes, and not a complete representation of the entire honeycomb aluminum panel 4-panel curtain wall. This partial image is only used to aid in understanding the structure, design features, or construction details of the honeycomb aluminum panel 4-panel curtain wall, and cannot represent the overall shape and scale of the entire honeycomb aluminum panel 4-panel curtain wall.

[0033] like Figure 3As shown, each support unit includes a support adapter pipe 5, which is welded to the top of the steel frame 1. The upper end of the support adapter pipe 5 is threadedly connected to a support pipe 6. Since the support pipe 6 and the support adapter pipe 5 are connected by threads, the purlin 2 is welded to the top of the support pipe 6 after the height is adjusted by rotating the support pipe 6.

[0034] like Figure 3-5 As shown, each mounting unit consists of two mounting parts, which are arranged parallel to each other on the top of the purlin 2. Each mounting part includes an upper ear plate 7, a lower ear plate 8, a first connecting bolt 9, and a second connecting bolt 10. The lower ear plate 8 is welded to the top of the purlin 2. The upper side of the lower ear plate 8 has a first round hole 11 and a first arc-shaped hole 12, which are concentrically arranged. The lower side of the upper ear plate 7 has a second round hole 13 and a second arc-shaped hole 14, which are also concentrically arranged. The upper ear plate 7 can... Rotating around the first circular hole 11, the first connecting bolt 9 passes through the first circular hole 11 and the second circular hole 13 to fix the upper ear plate 7 to the lower ear plate 8. The second connecting bolt 10 passes through the first arc-shaped hole 12 and the second arc-shaped hole 14 to further fix the upper ear plate 7 and improve its stability. The honeycomb aluminum plate 4 can be directly installed on the upper ear plate 7 or installed on the upper ear plate 7 through the angle steel 30. In this embodiment, the angle steel 30 is connected to the upper ear plate 7 by bolts, and the honeycomb aluminum plate 4 is installed on the top of the angle steel 30 by bolts.

[0035] like Figure 6 As shown, the positioning mechanism includes a first positioning unit and a second positioning unit. The first positioning unit is used to position the support unit, and the second positioning unit is used to position the installation unit.

[0036] like Figure 6-7As shown, the first positioning unit includes a positioning rod 15, which is welded to the steel frame 1. Its height is equal to the installation height of the support unit. The positioning rod 15 allows for preliminary positioning of the support unit's installation position and provides a reference for the support unit's installation height. A positioning screw 19 is rotatably connected to the support adapter pipe 5. Specifically, the positioning screw 19, from left to right, includes a smooth section 20, a threaded section 21, a limiting section 22, and a positioning section 23. These four parts are integrally formed. A connecting seat 18 is rotatably mounted on the smooth section 20, which can be threadedly connected to the threaded section 21. A slider 24 is threadedly connected to the threaded section 21, forming a lead screw pair with the threaded section 21. A guide rod 26 is welded to the support adapter pipe 5, allowing the slider 24 to slide. The guide rod 26 is mounted on the guide rod 26, which does not contact the connecting seat 18. The limiting section 22 rotates and engages with the support adapter pipe 5. The positioning section 23 is located inside the support adapter pipe 5. The right end of the positioning section 23 is a spherical surface. A corresponding spherical groove is opened on the first positioning rod 15. The spherical surface can contact the spherical groove and can rotate within the spherical groove. The support adapter pipe 5, positioning screw 19, guide rod 26, connecting seat 18, and slider 24 are prefabricated integrated precast components in the factory. When positioning the support adapter pipe 5, first, the support adapter pipe 5 is fitted onto the first positioning rod 15. The position of the support adapter pipe 5 is adjusted so that the spherical surface of the positioning section 23 contacts the spherical groove on the first positioning rod 15, thus achieving the positioning of the support adapter pipe 5. Then, the support adapter pipe 5 is welded to the steel frame 1.

[0037] like Figure 6As shown, the second positioning unit includes two positioning blocks 25, which are slidably mounted on the purlins 2 on the front and rear sides of the installation unit, respectively. A connecting block 29 is welded between the two positioning blocks 25, and a push rod 27 is welded to the bottom of the connecting block 29. A strip hole 28 for the push rod 27 to move is opened on the purlin 2. The inclined surface of the positioning block 25 near the upper ear plate 7 can contact the upper ear plate 7. A second positioning rod is welded to the inclined surface of the positioning block 25 near the upper ear plate 7. A first positioning hole is opened on the inclined surface of the upper ear plate 7 near the positioning block 25, and the second positioning rod can be inserted into the first positioning hole. The positioning block 25, connecting block 29, and push rod 27 are prefabricated integrated second prefabricated parts in the factory, and the positioning block 25 matches the prefabricated upper ear plate 7. The top of the slider 24 has a second positioning hole, and the push rod 27 can be inserted into the second positioning hole to realize the insertion of the slider 24 and the push rod 27. In severe weather (such as strong winds and heavy rain), this design prevents the connection between the upper ear plate 7 and the lower ear plate 8 from loosening, thus improving the stability of the honeycomb aluminum panel 4. After the angle of the honeycomb aluminum panel 4 is adjusted, rotating the positioning screw 19 causes the slider 24 to move horizontally towards the side closer to the upper ear plate 7. This, in turn, causes the push rod 27 to push the positioning block 25 towards the side closer to the upper ear plate 7, allowing the second positioning rod to be inserted into the first positioning hole. The inclined surface of the positioning block 25 near the upper ear plate 7 can then contact the upper ear plate 7, thus accurately positioning the upper ear plate 7. Since the purlin 2 is inclined, if the positioning block 25 is directly used to block between the upper ear plate 7 and the purlin 2 to limit the upper ear plate 7, the positioning block 25 may slide down the purlin 2, making it impossible to position the upper ear plate 7. This technical solution, by connecting the second prefabricated component to the first prefabricated component, can quickly achieve the positioning of the upper ear plate 7.

[0038] like Figure 6 As shown, the steel frame 1 is also equipped with a No. 3 prefabricated component, which includes a clamping claw 16 and a connecting rod 17. The clamping claw 16 includes a clamping part and a hand-held part. The clamping part can be clamped on the steel frame 1 by a torsion spring. The connecting rod 17 is welded to the rear side of the hand-held part. The connecting seat 18 has a connecting hole, and the connecting rod 17 can be inserted into the connecting hole. Since the limiting section 22 rotates and is engaged with the support adapter pipe 5, the limiting section 22 and the support adapter pipe 5 are fixed by friction. After the positioning block 25 is positioned on the ear plate 7, in order to prevent the positioning screw 19 from rotating, after the positioning block 25 is positioned, the connecting seat 18 is rotated so that the connecting seat 18 is threadedly connected to the threaded section 21. Then the connecting rod 17 is inserted into the connecting hole to improve the stability of the positioning block 25.

[0039] The construction method for honeycomb aluminum panel curtain walls includes the following steps: S1: Installation and construction preparation of the steel frame; S1.1: Use 3DMAX software to model, determine the spatial coordinates of steel frame 1 according to the modeling parameters, and install steel frame 1; S1.2: Erect steel pipe scaffolding, using Q235 ordinary steel pipes; S1.3: Use BIM technology to model the steel frame 1 and pre-assemble it. Number the upper ear plate 7, lower ear plate 8 and honeycomb aluminum plate 4 at each connection point to ensure that factory prefabrication and on-site construction are carried out simultaneously. S2: Positioning and installation of purlins; S2.1: Positioning and installation of the support unit; S2.1.1: The positioning of the support adapter pipe is achieved by using a total station to locate the spatial position and top elevation of the support unit. The No. 1 positioning rod 15 is used as a positioning stake and welded to the steel frame 1. The support adapter pipe 5 is then positioned by the first positioning unit and the No. 1 positioning rod 15 to ensure that the support adapter pipe 5 and the No. 1 positioning rod 15 are coaxial, thus ensuring the accuracy of the purlin 2 installation position. S2.1.2: Weld the support adapter pipe 5 to the steel frame 1. The weld quality grade is grade three. After welding, remove the weld slag and apply two coats of anti-rust paint. S2.1.3: Adjust the height of the support tube 6 to the top elevation of the first positioning rod 15; S2.1.4: The reinforcing rib 31 on the support unit is a custom-made part; S2.1.4.1: The distance between the purlin 2 and the steel frame 1 is within 300mm, and the reinforcing rib 31 is only set at the lower end of the support unit; S2.1.4.2: The distance between the purlin 2 and the steel frame 1 is more than 300mm, and reinforcing ribs 31 are provided at both the upper and lower ends of the support unit; S2.2: Purlin hoisting: Purlin 2 is the raw material, which is cut and processed on site according to the actual size of the corresponding part. Purlin 2 is hoisted to each work surface by hoisting equipment. During hoisting, each work surface is equipped with a supervisor, and only one purlin 2 is hoisted at a time. S2.3: Purlin positioning: First, purlin 2 is suspended on support pipe 6 without being fixed, so that it is in a free state that can be adjusted in all directions. Then, the lower ear plate 8 on the same side of the upper and lower ends of purlin 2 is positioned by measuring with a total station. The spatial position of purlin 2 is adjusted according to the position of the lower ear plate 8 after measurement. S2.4: Purlin Installation: After measurement and positioning, weld purlin 2 to support pipe 6. All welds should be uniform to ensure quality. The weld quality grade is three. After welding, remove the weld slag and apply two coats of anti-rust paint. S3: Installation and angle correction of honeycomb aluminum panels; S3.1: Positioning and Installation of Lower Ear Plates: After the purlin 2 is positioned and welded, input the modeling coordinate points using a total station, and measure the position of the lower ear plate 8 on the purlin 2 using a small prism. After the measurement is completed, spot weld the lower ear plate 8 onto the purlin 2. Use the same method to measure, position, and weld the remaining lower ear plates 8. After the ear plates in this area are spot welded, apply full welding to all of them. All welds should be uniform to ensure quality. The weld quality grade is three. After welding, remove the welding slag and apply two coats of anti-rust paint. S3.2: Fluorocarbon paint spraying: The lower ear plate 8 is made of Q345 steel plate, deburred, and after being welded to the purlin 2, it is fluorocarbon sprayed together with the purlin 2; the angle steel 30 is made of Q345 steel plate, hot-dip galvanized and then fluorocarbon sprayed; the upper ear plate 7 is made of Q345 steel plate, deburred, hot-dip galvanized and then fluorocarbon sprayed.

[0040] S3.3: Angle steel model drawing and processing: Since the size and adjustment angle of each honeycomb aluminum panel 4 are not the same, the matching angle steel 30 also needs to be adjusted according to the width and slope of the honeycomb aluminum panel 4. Therefore, the angle steel 30 needs to be designed and laid out in detail. The thickness of the angle steel 30 is 4mm, and the cutting shape is determined according to the honeycomb aluminum panel 4. AutoCAD software is used to draw the left and right angle steel 30 models of each honeycomb aluminum panel 4, and then the factory processes them according to the models, laser engraving the number and spraying anti-rust paint. S3.4: Installation of honeycomb aluminum panels: Pass the No. 1 connecting bolt 9 through the No. 1 round hole 11 and the No. 2 round hole 13, but do not tighten the No. 1 connecting bolt 9 to ensure that the upper ear plate 7 can rotate, so as to facilitate the adjustment of the angle after the honeycomb aluminum panel 4 is installed. Install the angle steel 30 on the upper ear plate 7 with bolts. Use hoisting equipment to lift the honeycomb aluminum panel 4 to the corresponding working surface. Connect the honeycomb aluminum panel 4 to the angle steel 30 with T-bolts. Adjust the plane angle of the honeycomb aluminum panel 4 so that it is on the same plane as the aluminum panel on the same plane. After the position is adjusted, tighten the T-bolts. When connecting the angle steel 30 and the honeycomb aluminum panel 4, insert an asbestos gasket to avoid bimetallic contact corrosion.

[0041] S3.5: Angle correction of honeycomb aluminum panel: The angle between honeycomb aluminum panel 4 and purlin 2 is determined according to the modeling parameters. The angle of honeycomb aluminum panel 4 can be freely adjusted up and down by connecting bolt 9. After the angle is adjusted, connecting bolt 9 is locked. At the same time, connecting bolt 10 is used to fix the upper ear plate 7 and the lower ear plate 8 again.

[0042] S3.6: Positioning of the installation unit: After the angle of the honeycomb aluminum plate 4 is adjusted, the upper ear plate 7 is positioned by the second positioning unit. After positioning, the clamp 16 is welded to the steel frame 1.

[0043] S4: Cleaning and Finished Product Protection: After each honeycomb aluminum panel is installed, the surrounding area is cleaned to remove dust, silicone sealant, etc. After acceptance by the supervisor and other relevant departments, a dedicated person is assigned to protect the finished product to prevent dust and other contamination and to prevent human-caused damage until completion and handover for use.

[0044] Example 2 Based on Example 1, such as Figure 8 As shown, the inclined surface of the positioning block 25 near the upper ear plate 7 is a stepped surface, and the inclined surface of the upper ear plate 7 near the positioning block 25 is also a stepped surface. The stepped surface on the positioning block 25 matches the stepped surface on the upper ear plate 7. A No. 3 positioning rod is integrally formed on the stepped surface of the positioning block 25, and a No. 2 positioning hole is opened on the stepped surface of the upper ear plate 7. The No. 3 positioning rod can be inserted into the No. 2 positioning hole. By setting stepped surfaces on the positioning block 25 and the upper ear plate 7, on the one hand, the design of the stepped surface makes the contact between the positioning block 25 and the upper ear plate 7 tighter and more stable. Under severe weather conditions, such as strong winds and heavy rain, the honeycomb aluminum plate 4 will be subjected to strong wind forces. The interlocking of the stepped surfaces increases the friction and resistance between the upper ear plate 7 and the positioning block 25, effectively resisting the pushing and torsional effects of wind on the upper ear plate 7. This design makes the entire structure more robust in strong winds, reducing swaying and displacement caused by wind and improving the wind resistance of the honeycomb aluminum panel 4. At the same time, the stepped surfaces can better withstand forces from different directions, reducing the risk of deformation and damage caused by stress concentration. On the other hand, when the installation angle of the honeycomb aluminum panel 4 does not meet the requirements, there will be a mismatch between the stepped surfaces on the positioning block 25 and the upper ear plate 7. Therefore, it can be used to check whether the installation angle of the honeycomb aluminum panel 4 meets the requirements.
