[0022] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] Combined with attachment Figure 1 -Attached Figure 4 A hidden fixed assembled curtain wall includes a keel frame and several curtain wall units installed on the keel frame. The curtain wall unit includes a curtain wall mounting frame 1 and a panel 2 integrally arranged at the front end of the curtain wall mounting frame 1. The left inner edge of the curtain wall mounting frame 1 is installed with a hook profile 4 through a left countersunk bolt 3, and the right inner edge of the curtain wall mounting frame 1 is installed with a lap profile 6 through a right countersunk bolt 5. The left side of the curtain wall mounting frame 1 is fixed to the keel frame through the hook profile 4, and the right side of the curtain wall mounting frame 1 is embedded with the hook profile 4 of the adjacent curtain wall mounting frame 1 through the lap profile 6.

[0024] In one embodiment, a left countersunk groove 7 corresponding to the shape of the head of the left countersunk bolt 3 is provided at the upper and lower parts of the left rear end of the curtain wall mounting frame 1. The left countersunk bolt 3 can be slidably pushed into the left countersunk groove 7. A through hole for the left countersunk bolt 3 to pass through is provided on the hook profile 4. A left locking nut 8 located on the inner side of the hook profile 4 is threadedly connected to the left countersunk bolt 3.

[0025] The curtain wall mounting frame 1 has right recesses 9 on its upper and lower sides, corresponding to the shape of the head of the right countersunk bolt 5. The right countersunk bolt 5 can be slidably inserted into the recesses 9. The lap profile 6 includes a through-hole for the right countersunk bolt 5 to pass through, and the right countersunk bolt 5 is threadedly connected to a right locking nut 10 located inside the lap profile 6. In this embodiment, particular emphasis is placed on the fine-tuning and tightening mechanism between the curtain wall mounting frame 1, the lap profile 6, and the hook profile 4. The design of the left and right recesses 7 and 9 not only provides a smooth sliding path for the left and right countersunk bolts 3 and 5, but also ensures that the left and right countersunk bolts 3 and 5 are fully seated in their corresponding slots, preventing the exposed bolt heads from affecting aesthetics and potentially posing safety hazards. The use of the left and right locking nuts 8 and 10 allows the hook profile 4 and lap profile 6 to be fine-tuned by rotation after installation to achieve optimal tightening and installation accuracy. This design not only improves installation efficiency, but also ensures the stability and safety of the curtain wall unit in long-term use.

[0026] In one embodiment, the edge profile 6 includes an L-shaped connecting portion 601 and an embedded portion 602 provided at the rear end of the L-shaped connecting portion 601, and the L-shaped connecting portion 601 is in contact with the inner edge of the curtain wall installation frame 1;

[0027] The hook profile 4 includes a U-shaped connecting portion 401 and an L-shaped mounting portion 402 provided at the rear end of the U-shaped connecting portion 401. The U-shaped connecting portion 401 is fitted with the inner edge of the curtain wall mounting frame 1, and the L-shaped mounting portion 402 is fixed to the keel frame by countersunk screws 11.

[0028] A fitting notch 403 is formed between the U-shaped connecting portion 401 and the L-shaped mounting portion 402, and the mounting portion 602 of the overlap profile 6 is inserted into the fitting notch 403 of the adjacent hook profile 4. This embodiment focuses on the fitting structure between the overlap profile 6 and the hook profile 4 and the resulting improved sealing. The tight fit of the L-shaped connecting portion 601 against the inner edge of the curtain wall mounting frame 1 and the precise insertion of the mounting portion 602 into the fitting notch 403 ensure seamless connection between adjacent curtain wall units. This fitting structure also creates a natural waterproof barrier, effectively preventing the intrusion of external factors such as rain and dust.

[0029] In one embodiment, the keel frame includes several transverse keels 12 and longitudinal keels 13 spaced apart from the transverse keels 12. The transverse keels 12 are secured to the wall surface via expansion screws 14, and the L-shaped mounting portions 402 are secured to the longitudinal keels 13 via countersunk screws 11. This embodiment details the structural design of the keel frame and its role in providing stable support for the curtain wall system. The transverse keels 12 are rigidly connected to the wall surface via expansion screws 14, ensuring the overall stability of the keel frame. The spaced-apart arrangement of the longitudinal keels 13 allows for flexible layout of curtain wall units. By adjusting the spacing of the longitudinal keels, curtain wall units of varying sizes and shapes can be accommodated, achieving personalized designs. Furthermore, the longitudinal keels 13 serve as the primary load-bearing structure of the curtain wall unit. Securely connected to the L-shaped mounting portions 402 of the trim profile 4 via countersunk screws 11, they evenly distribute the weight of the curtain wall unit across the keel frame, improving the load-bearing capacity and safety of the entire curtain wall system. This connection method also facilitates maintenance and replacement of curtain wall units.

[0030] In one embodiment, the transverse keels 12 and the longitudinal keels 13 are both square tubes. The square tube structure has good bending stiffness and load-bearing capacity, and is suitable as a supporting structure for the curtain wall system, which can ensure the stability and safety of the overall curtain wall structure.

[0031] In one embodiment, the curtain wall mounting frame 1 and the panel 2 are made of composite aluminum panels. Composite aluminum panels are light in weight and high in strength, which can reduce the overall weight of the curtain wall system while maintaining good load-bearing capacity and wind pressure resistance.

[0032] Working principle: First, assemble the curtain wall unit. Each curtain wall unit consists of a curtain wall mounting frame 1, a panel 2, a hook profile 4 and a lap profile 6. The panel 2 is integrally arranged at the front end of the curtain wall mounting frame 1. On the left inner edge of the curtain wall mounting frame 1, the hook profile 4 is installed in place by the left countersunk bolt 3, and ensure that the left countersunk bolt 3 is slid into the left recessed groove 7 at the left rear end of the curtain wall mounting frame 1, and then locked with the left locking nut 8 on the inner side of the hook profile 4. Similarly, on the right inner edge of the curtain wall mounting frame 1, the lap profile 6 is installed by the right countersunk bolt 5, the right countersunk bolt 5 is pushed into the right recessed groove 9, and locked with the right locking nut 10 on the inner side of the lap profile 6. At this point, a complete curtain wall unit is assembled.

[0033] Next, secure the entire curtain wall unit to the keel. The keel consists of several transverse ribs 12 and spaced longitudinal ribs 13. The transverse ribs are securely fastened to the wall using expansion screws 14. Now, align the L-shaped mounting portion 402 of the curtain wall unit's trim profile 4 with the longitudinal ribs 13 and secure them using countersunk screws 11. This secures the left side of the curtain wall unit to the keel.

[0034] Subsequently, when installing the adjacent curtain wall unit, proceed from the left side of the already installed unit. Align and insert the mounting portion 602 of the new curtain wall unit's overlapping profile 6 into the interlocking notch 403 formed between the U-shaped connecting portion 401 and the L-shaped mounting portion 402 of the previous curtain wall unit's hook profile 4, achieving a seamless connection between the two units. Repeat this process until all curtain wall units are installed in order and secured to the keel.

[0035] This installation method not only ensures a tight connection between curtain wall units and the stability of the overall structure, but also greatly improves the aesthetics and waterproof and dustproof performance of the curtain wall because the overlapping and hook profiles are hidden on the outside. It is an efficient and elegant solution for the installation of modern building curtain walls.

[0036] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
