[0052] The following is the most preferred embodiment of the invention's method for constructing a sound-absorbing ceiling with an umbrella-shaped perforated aluminum plate under a curved roof, as follows, with reference to the attached drawings. Figure 2-6 As shown:

[0053] 1) Installation of ceiling transfer layer

[0054] Galvanized angle steel hangers of 75mm*50mm*4mm are fixed by Φ10mm expansion screws, and each galvanized angle steel hanger is fixed by two Φ10mm expansion screws. The vertical support frame is made of galvanized angle steel of 50mm*50mm*5mm, and the galvanized angle steel of the vertical support is fixed to the upper 75*50*4mm galvanized angle steel hanger by welding. The steel structure transfer layer is made of galvanized square tube of 50mm*50mm*5mm, and the galvanized square tube of the transfer layer is fixed to the galvanized angle steel of the vertical support by welding. The steel structure transfer layer is arranged according to the arc roof shape, with a spacing of about 1200mm along the long direction of the venue and a spacing of about 900mm along the short direction of the venue.

[0055] 2) Wire positioning

[0056] ① The x and y coordinate points of the four corner points of the curved grid steel frame are marked on the arc roof or the mounting angle steel by using an infrared plumb instrument to measure upward.

[0057] ② According to the architectural one-meter line handed over by the measurement, the height is marked upward, and the spatial horizontal position of the marked height is obtained by using an infrared level.

[0058] ③ The z coordinates of the four corners of the steel frame are obtained according to the spatial height of the curved grid combined with the model of the arc-shaped wood transfer aluminum plate suspended ceiling, and the z coordinate position of the steel frame is obtained by measuring with a tape measure combined with the height marked in the previous step.

[0059] 3) Fixing the arc-shaped modeling curved grid

[0060] ① Curved grid frame system. According to the position of the lower hanging curved grid obtained by the measurement, the horizontal steel frame along the installation direction of the grid is installed, the horizontal steel frame is made of galvanized square tube of 50mm*50mm*5mm, and the horizontal steel frame is arranged at an interval of 2m per rod, according to the grid width, one horizontal square tube is used on both sides of the grid to form a curved frame structure by replacing straight with curved, and a short square tube is added at the position of 2m connection of the horizontal square tube to reinforce the entire frame system.

[0061] ② Temporary fixation of horizontal steel frame. The horizontal steel frame is temporarily fixed by Φ8mm screw rod, and the ends of the suspension rod are fixed to the steel structure transfer layer system and the horizontal galvanized square tube by using 30mm*60mm*1.5mm L-shaped hangers, and the horizontal steel frame is temporarily fixed by screwing to facilitate subsequent position adjustment.

[0062] ③Install the lower-hung curved grille. The upper portion of the specially designed curved grille features an inward-concave upper flange with a height of 15mm and a width of 20mm. This flange is used to secure the lower-hung curved grille to the horizontal galvanized square tube using self-tapping screws. During installation, the horizontal frame and curved grille are adjusted based on the curved grille's shape and positioning. Once the position is correct, add self-tapping screws and secure the lower-hung curved grille at a spacing of 300mm per screw. The self-tapping screws are securely fixed.

[0063] ④ Reinforce the curved grille frame system. After the curved grille is positioned, the entire curved grille frame system is reinforced. A vertical support structure is used to connect the horizontal galvanized square tubes that fix the grille to the steel structure transfer layer. The vertical support structure uses 50mm*50mm*5mm galvanized square tubes. Both ends of the vertical support structure are fixed to the horizontal steel frame and the steel structure transfer layer system by welding. The horizontal galvanized square tubes on both sides are connected to the vertical support structure respectively. Combined with the layout of the upper steel structure transfer layer, the vertical support structure is set at a spacing of approximately 1800mm.

[0064] ⑤ Anti-rust treatment. After the entire curved grid frame system is reinforced, all welded parts are treated with anti-rust treatment. Welding slag is knocked off at the welding locations, and anti-rust paint is applied multiple times according to the anti-rust treatment requirements to ensure that the anti-rust treatment of the welded parts meets the quality requirements.

[0065] 4) Install the short side grille in the middle of the curved grille

[0066] Fix the short side grille (hereinafter referred to as the crossbar) in the middle of the curved grille. According to the curved wood transfer aluminum plate model rendering and decoration blueprint, a crossbar is set between two adjacent lower-hanging curved grilles. According to the width of the crossbar, the curved grille is customized with a reserved notch during processing and production. The length of the processed crossbar is slightly larger than the distance between the two adjacent curved grilles. Before inserting the crossbar into the notch of the curved grille, drive a self-tapping screw into the bottom of the crossbar end on both sides to fix the crossbar and prevent it from falling off. According to the position of the reserved notch, insert the crossbar directly into the notch of the curved grille.

[0067] 5) Install perforated aluminum panels

[0068] Similar to the construction of an umbrella, after the frame is completed, the surface layer begins to be installed. Following the 15mm upward turndown of the curved grille, the perforated aluminum cladding is directly positioned over the upper edge. Once the cladding is accurately positioned, self-tapping screws are used from top to bottom to secure it to the upper edge of the curved grille. The screws are spaced 300mm apart.

[0069] 6) Install the backing glass wool

[0070] In order to enhance the sound absorption function of the curved wood-transferred aluminum ceiling, glass wool is added to the back of the ceiling. The glass wool is wrapped with silk cloth and placed on the cladding perforated aluminum plate. The cladding perforated aluminum plate is customized with a 15mm folded edge during processing and production, which can not only ensure that the entire aluminum plate will not be deformed, but also be used to fix the glass wool to prevent it from falling off.

[0071] The embodiment of the present invention discloses a method for constructing a sound-absorbing ceiling with an umbrella-shaped curved perforated aluminum plate under a curved roof, which has the following interesting technical effects: the curved umbrella-shaped shape adopted by the present invention has a more refined and complex shape compared to the original hyperbolic ceiling which is only a double-sided aluminum plate, thereby improving the overall decorative and aesthetic effect; the present invention adopts a perforated curved aluminum plate, and at the same time adds sound-absorbing cotton on the back, which has more excellent acoustic performance; compared with the hyperbolic ceiling of the prior art which is only fixed with a screw rod and has insufficient stability, the present invention adopts a steel structure transfer layer frame, which has stronger overall stability; the connection structure used in the construction method of the invention is simple, the construction and installation are convenient, and the selected materials are light in weight and high in strength, thereby improving the quality of the project.
