[0043] It should be noted that the integration of the inner wall of the curved building is the integration of the wall and the roof of the curved building, thereby improving the aesthetics of the curved building and at the same time improving the construction efficiency.

[0044] Continue to refer to Figure 3 and Figure 4 In this embodiment, the curved frame includes multiple curved keels 10, which are connected in sequence along the extension direction of the curved building.

[0049] During the installation process, the arc-shaped support plate 12 is located at the bottom of the arc-shaped connecting plate 13.

[0050] The distance between each two adjacent arc-shaped support plates 12 ranges from 200 mm to 600 mm.

[0051] Continue to refer to Figure 1 In this embodiment, the hanging assembly 30 includes multiple hanging rods 31 and multiple adjusting screw rods 32. The top ends of the multiple hanging rods 31 are connected to the purlin 2, and the bottom ends of the multiple hanging rods 31 are connected to the curved surface frame. The top ends of the multiple adjusting screw rods 32 are connected to the purlin 2, and the bottom ends of the multiple adjusting screw rods 32 are connected to the curved surface frame; by setting the adjusting screw rods 32, the adjusting screw rods 32 are used to adjust the shape of the corresponding curved keel 10 so that the curved surface of the curved keel 10 remains smooth.

[0052] Specifically, each curved keel 10 is welded to the purlin 2 through multiple hangers 31, and multiple hangers 31 are arranged at intervals. An adjusting screw rod 32 is installed at the geometric center position of each curved keel 10. The adjusting screw rod 32 is used to adjust the shape of the curved keel 10 so that the overall curved surface of the curved skeleton remains smooth.

[0053] The suspension rod 31 can be made of angle steel, rectangular tube or square tube, and the adjusting screw rod 32 can be made of a full-thread screw rod.

[0054] Continue to refer to Figure 2 as well as Figures 5 to 8In this embodiment, the curved seamless sound-absorbing component 20 includes a curved sound-absorbing panel and a sound-transmitting coating 22. One side of the curved sound-absorbing panel is connected to the side of the curved frame facing away from the hanging component 30, and the sound-transmitting coating 22 is sprayed on the side of the curved sound-absorbing panel facing away from the curved frame.

[0055] Specifically, the curved sound absorbing panel is fixed to the curved frame by a dual fixing method of adhesive 23 and self-tapping screws 24 with flanges.

[0056] The adhesive 23 may be applied using silicone structural adhesive or epoxy adhesive. The adhesive 23 is applied in an S-shape, and the thickness of the adhesive 23 is ≥3 mm.

[0059] In order to prevent the sealant from breaking, an anti-crack net 25 is adhered to the surface of the sealant. The anti-crack net 25 is a fiber mesh with self-adhesive backing. The width of the anti-crack net 25 ranges from 30mm to 70mm. In this embodiment, the width of the anti-crack net 25 is 50mm. The anti-crack net 25 is adhered to the center of the sealant.

[0060] Specifically, the flexible particle sound-absorbing board 21 is made of granular sound-absorbing material with a moisture absorption capacity (1×10-3kg / ㎡): ≤55. The flexible particle sound-absorbing board 21 is in a flat state. The flexible particle sound-absorbing board 21 bends when subjected to force. After the force disappears, the flexible particle sound-absorbing board 21 does not return to the flat state. The flexible particle sound-absorbing board 21 deforms along with the curved keel 10 to form a curved surface layer.

[0061] During installation, adhesive 23 is applied in an S-shaped pattern to the side of the curved keel 10 facing away from the hanger 31. The flexible particle acoustic panel 21 is then adhered to the curved keel 10 using the applied adhesive 23. Flange-mounted self-tapping screws 24 are then used to secure one side of the panel 21. The flange-mounted self-tapping screws 24 are then tightened along the curvature of the curved keel 10 while gradually pressing downward, ensuring that the panel 21 is evenly and tightly attached to the curved support plate 12. The long sides of the flexible particle acoustic panel 21 are laid parallel to the curved support plate 12 to maximize the surface contact area. The panels 21 are installed with staggered seams to ensure that there are no through-holes and prevent cracking.

[0062] After the flexible particle sound-absorbing panels 21 are installed, they are illuminated from the side using light, and the protruding parts of the flexible particle sound-absorbing panels 21 are polished smooth using a washboard to ensure that the surface of the curved sound-absorbing panels is smooth and the height difference between two adjacent flexible particle sound-absorbing panels 21 does not exceed 1 mm; the polished thickness of the flexible particle sound-absorbing panels 21 is ≤4 mm.

[0069] In order to improve the firmness of the connection between two adjacent curved keels 10, after welding is completed at the fitting position of the two adjacent curved keels 10, bolts are used to fix them. The double fixation improves the firmness of the curved skeleton.

[0070] S1012. After all the curved keels 10 are installed, the adjusting screw 32 in the hanging assembly 30 is installed at the midpoint of each curved keel 10. The adjusting screw 32 is adjusted to change the shape of the curved keel 10 to make the curvature of the curved skeleton smooth.

[0078] The adhesive 23 may be applied using silicone structural adhesive or epoxy adhesive. The adhesive 23 is applied in an S-shape, and the thickness of the adhesive 23 is ≥3 mm.

[0079] S10212. Fix one side of the flexible particle sound absorbing board 21 with a flanged self-tapping screw 24, and gradually press down along the curvature direction of the curved keel 10 while tightening the flanged self-tapping screw 24, so that the flexible particle sound absorbing board 21 is evenly and tightly attached to the arc-shaped support plate 12 of the curved keel 10.

[0080] Specifically, the distance between each two adjacent flanged self-tapping screws 24 ranges from 150 mm to 250 mm. In this embodiment, the distance between each two adjacent flanged self-tapping screws 24 is 200 mm, and the top of the nut of the flanged self-tapping screw 24 is sunk into the flexible particle sound absorbing board 21 by 2 mm.
