[0021] Figures 1 to 3A large-format cement fiberboard curtain wall system includes a steel square tube 10. Multiple first aluminum alloy angle brackets 20 are fixedly connected to one side of the steel square tube 10 along its height. An aluminum alloy square tube 30 is fixedly connected to one side of each first aluminum alloy angle bracket 20. A second square tube 35 is fixedly connected to one side of each aluminum alloy square tube 30. A cement fiberboard 100 is fixedly connected to one side of each aluminum alloy square tube 30 and second square tube 35 via flat-head nails 105. An aluminum plate 15 is pressed between the steel square tube 10 and the first aluminum alloy angle brackets 20. Cement fiberboard 100 is symmetrically arranged on both sides of the steel square tube 10 along its height. The aluminum alloy square tube 30 has dimensions of 40*40*3mm. The aluminum plate 15 is waterproof, 1.5mm thick, and the joints are blackened.

[0022] The outer wall of the cement fiberboard 100 is provided with evenly distributed strip grooves 101, which are fixedly connected to the aluminum alloy square tube 30 by flat-head nails 105. A protective agent is applied to the surface of the cement fiberboard 100, and a gap 200 is provided between adjacent cement fiberboards 100. The cement fiberboard 100, with its protective agent, has a total thickness of 15mm, a groove depth of 3mm, is Class A fire resistant, and has an effective net thickness of 12mm.

[0023] A first connecting hole 109 is provided on one side of the steel square tube 10 along its height direction. A first connecting plate 21 is provided on the first aluminum alloy angle aluminum 20. The first connecting plate 21 has a second connecting hole 211. The first connecting hole 109 and the second connecting hole 211 are fixedly connected by screws 14. A rubber pad 13 is pressed between the first connecting plate 21 and the aluminum plate 15 and fixedly connected by screws 14. The screws 14 are glued and have a black surface treatment.

[0024] The first aluminum alloy angle aluminum 20 is provided with a second connecting plate 22, and the second connecting plate 22 is provided with a third connecting hole 221. The third connecting hole 221 is fixedly connected to the aluminum alloy square tube 30 by bolts 50.

[0025] To provide a supporting frame for the cement fiberboard 100, the side wall of the aluminum alloy square tube 30 is provided with a through hole 31, through which a bolt 50 passes. The bolt 50 is locked to the first aluminum alloy angle 20 by a flat washer, a spring washer, and a nut. The side wall of the aluminum alloy square tube 30 is provided with a second aluminum alloy angle 40 with a thickness of 3mm.

[0026] This system uses steel columns and beams as the main keel in its main structure, covered with waterproof aluminum panels. Elevation limit aluminum alloy angle brackets are installed on the outer side of the waterproof aluminum panels, also serving as load-bearing components. The panels are made of unitized panel profiles. Aluminum alloy square tubes are used to form unit frames via angle brackets. Holes are pre-drilled in the cement fiberboard, and the cement fiberboard is evenly fixed to the aluminum alloy frame using specialized flat-head nails. After assembly, the panels are hoisted as a whole, lowered onto the limit brackets, and after minor leveling, fixed to the main keel with machine-made nails. This unitized approach shifts the single-panel layout and installation work to the ground, reducing panel handling, lowering the breakage rate, and improving joint accuracy. The unitized design, reinforced by an aluminum alloy frame, strengthens the overall panel strength. This large-panel cement fiberboard unit hoisting system makes installation more convenient and faster, greatly improving safety and production efficiency.
