[0002] Fire-resistant curtain walls achieve fire protection by using fire-resistant materials for the curtain wall panels and a metal frame to support them during installation. However, existing fire-resistant curtain wall structures have the following shortcomings in practical applications: Low assembly and disassembly efficiency: Traditional curtain wall structures mostly use fixed connections, requiring a large number of tools for on-site welding or complex bolt fixing during installation. Disassembly is cumbersome, time-consuming, and labor-intensive, making it difficult to meet the needs of rapid construction and maintenance. Furthermore, it is not easy to remove and replace the wall panels in the middle part after the curtain wall is laid.

[0003] Curtain wall panel installation is inconvenient: In traditional structures, the fixing of curtain wall panels requires multiple positioning on the frame, which can easily lead to deviations during installation. Furthermore, the gaps between panels are difficult to control precisely, affecting fire resistance and aesthetics. Utility Model Content

Slots communicating with the mating openings are provided at both corners of the docking seat, and each mating opening has a symmetrically provided mounting threaded hole at one end. One end of one of the mating openings has a first countersunk hole that mates with the first mounting threaded hole. One end of the locking bolt is detachably screwed into the countersunk locking threaded hole in the middle of the front side wall of the docking seat. A pair of sliding rods are symmetrically arranged in the middle of the docking seat. Located on the upper and lower sides of the locking bolt, the top seat is trapezoidal and movably mounted on a pair of sliding rods.

[0013] The fireproof curtain wall structure proposed in this utility model has the following advantages: 1. Rapid assembly and disassembly improves construction efficiency: The adapter unit and the frame unit are connected by a slot and locking rod structure, which can be plugged in and pulled out. There is no need for complicated welding or multi-step bolt fixing. During installation, only the locking bolt needs to be turned to lock it. During disassembly, the reverse operation can be used to quickly separate them, which greatly shortens the construction cycle. The sockets of the frame unit and the fitting ports and slots of the adapter unit are precisely aligned to achieve seamless connection, reduce on-site debugging time, and meet the needs of rapid assembly in engineering projects.

[0014] 2. Flexible transition, adaptable to diverse layouts: A single transition unit can achieve right-angle transition, and two transition units can be spliced ​​together to form a cross-shaped transition. Through the splicing method of the first bolt, it can be freely combined according to the building structure, flexibly adapting to complex curtain wall layouts such as L-shaped and cross-shaped, expanding the application scenarios.

[0015] 3. Sturdy structure, ensuring safety performance: The locking rod inside the adapter unit engages with the inclined wall of the force plate through the top seat. When the locking bolt is tightened, the top seat moves backward, pushing the force plate up and causing the locking rod to extend and securely lock the socket. Combined with the restoring force of the spring, a two-way locking structure is formed to prevent loosening and improve overall stability. The curtain wall panels are designed with right-angle connections between the panel grooves and the panel openings, and are fixed by embedding the four corners into the panel openings to prevent displacement. At the same time, the docking structure between the panel grooves and the sockets ensures that the gaps between the curtain wall panels are uniform after installation, enhancing fire resistance and sealing. In addition, since the panel grooves are symmetrically set on both sides of the wall panel frame, other materials can be installed on the back of the curtain wall panels during installation to enhance fire resistance and prevent external flames from entering the building.

[0016] 4. Simplified structure, reducing maintenance costs: The modular design of the transition unit and the frame unit reduces the number of parts, and each part can be disassembled and replaced. Maintenance does not require the entire curtain wall to be disassembled, reducing maintenance difficulty and cost. Workers only need to carry tools to tighten the locking bolts to work at height, without the need for bolt and hole, panel hole and other calibration and screwing operations. Countersunk threaded holes are equipped with retainers to prevent bolt corrosion and external impacts, extend the service life of the structure, reduce the amount of maintenance work in the later stage, and improve the overall appearance.

At this time, the head of the second bolt 23 is sunk into the socket 22 to ensure that the surface is flat; the two wall panel frames 21 are aligned at right angles and their respective sockets 22 are fitted together, so that the openings 62 of the two sockets 22 are joined to form a right angle connection structure; the other end of the fitted socket 22 is inserted into the slot 42 of the adapter unit 1, and the outer wall of the socket 22 is tightly fitted with the fitting port 41 of the adapter unit 1 and the inner wall of the slot 42 to achieve seamless insertion.

[0021] like Figure 2 , Figure 3 and Figure 4As shown, as a further embodiment of this utility model, the adapter unit 1 includes a docking seat 11, a locking bolt 12, a pair of sliding rods 13, a top seat 14, a bearing 15, two pairs of locking rods 16, a pair of force-bearing plates 17, and two pairs of springs 18. The docking seat 11 has a rectangular cavity structure. A countersunk locking threaded hole 43 is provided in the middle of the front side wall of the docking seat 11. A retaining cap 8 is detachably fastened in the countersunk locking threaded hole 43 and is fitted onto the first bolt 3. L-shaped mating openings 41 are provided at both corners of the right side wall of the docking seat 11. The connected slot 42 and the mating opening 41 each have symmetrically provided threaded holes 5 at one end. One end of the mating opening 41 has a first countersunk hole that mates with the first threaded hole 5. One end of the locking bolt 12 is detachably screwed into the countersunk locking threaded hole 43 in the middle of the front side wall of the mating seat 11. A pair of sliding rods 13 are symmetrically arranged in the middle of the mating seat 11 and located on the upper and lower sides of the locking bolt 12. The top seat 14 is trapezoidal and is movably fitted onto the pair of sliding rods 13. Both the upper and lower side walls of the top seat 14 are inclined walls, and the length of the front side wall of the top seat 14 is greater than that of the rear side wall. The bearing 15 is fixedly embedded in the middle of the front side wall of the top seat 14, and the middle part of the bearing 15 is fixedly fitted onto the locking bolt 12. One end of each of the two pairs of locking rods 16 is symmetrically embedded in the lower inner wall of the slot 42, and the other end of each locking rod 16 is located in the docking seat 11. One end of each locking rod 16 can extend and retract. A pair of force plates 17 are fixedly set between the other ends of the locking rods 16, and the force plates 17 can fit against the top seat 14. The force plates 17 are pushed up by the rearward movement of the top seat 14. Two pairs of springs 18 are movably fitted onto the other end of each locking rod 16, and are located between the force plates 17 and the docking seats. Between the inner walls of 11; the mating opening 41 and socket 22 of the mating seat 11 are used to connect the frame unit 2. The mating seats 11 are installed and combined relative to each other by the first bolt 3, so that the four corner parts can be installed by the slot 42 respectively, realizing the cross-shaped transition. The locking bolt 12 drives the top seat 14 to move on the slide rod 13, and the height change of the contact between the inclined wall surface of the top seat 14 and the force plate 17 is used to push the force plate 17, thereby pushing the locking rod 16 and compressing the spring 18 to lock. The mating seats 11 are connected relative to each other by the first bolt 3 passing through the first mounting threaded hole 5.

[0022] More specifically, during installation, the locking bolt 12 is rotated clockwise to screw it into the countersunk locking threaded hole 43, causing the top seat 14 to move backward along the slide rod 13. As the locking bolt 12 rotates, it is movably connected to the top seat 14 via the bearing 15. The inclined wall of the top seat 14 pushes the force plate 17 upward, and the force plate 17 causes the locking rod 16 to extend towards the slot 42, thereby causing the locking rod 16 in the two corresponding slots 42 on the mating seat 11 to extend out and insert into the corresponding holes of the socket 22, thus achieving locking and fixing. At this time, the spring 18 is compressed, storing elastic potential energy to prevent the locking bolt 12 from rotating due to vibration.

[0023] As a further embodiment of this utility model, after the socket 22 is attached to the other end, it can be inserted into the slot 42 of the docking seat 11, and the socket 22 is fitted with the fitting port 41 and the slot 42 for seamless insertion; the other end of the socket 22 can be fitted onto the locking rod 16 for locking and fixing; after the socket 22 is attached to the other end, the plate openings 62 are connected to each other and the plate slots 61 of the two wall panel frames 21 are connected at a right angle through the plate openings 62; the curtain wall panel 7 is inserted into the plate slots 61 of the wall panel frame 21, and the four corners of the curtain wall panel 7 are respectively located in the plate openings 62.

[0024] Assembly of frame unit 2: Place one end of the wall panel frame 21 of the two frame units 2 perpendicularly to each other, so that the sockets 22 installed on each are in contact with each other; at this time, the plate openings 62 of the two sockets 22 are precisely aligned to form a right-angle connection structure. This connection structure corresponds to and matches the plate grooves 61 of the two wall panel frames 21, ensuring that the plate grooves 61 of the wall panel frames 21 are connected at right angles through the plate openings 62, providing a continuous embedding path for the subsequent installation of the curtain wall panel 7.

[0025] The frame unit 2 and the adapter unit 1 are connected by inserting the other ends of the two sockets 22 (the ends away from the wall panel frame 21) into the slots 42 at the two corners of the docking seat 11 of the adapter unit 1. During the insertion process, the outer wall of the socket 22 is tightly fitted with the inner wall of the L-shaped fitting port 41 of the docking seat 11 and the inner wall of the slot 42 to achieve seamless insertion, ensuring the sealing and structural stability of the connection part, and avoiding shaking or fire resistance degradation caused by gaps.

[0026] Locking and securing the socket 22 to the adapter unit 1: After the socket 22 is fully inserted into the slot 42, operate the locking bolt 12 of the adapter unit 1 to screw it into the countersunk locking threaded hole 43, causing the top seat 14 to move backward along the slide rod 13; the inclined wall of the top seat 14 pushes the force plate 17 upward, thereby causing the locking rod 16 to extend towards the slot 42, so that one end of the locking rod 16 is precisely fitted into the corresponding part of the socket 22, completing the locking and securing. At this time, the spring 18 is in a compressed state, providing a reverse force through elastic potential energy, enhancing the locking force between the locking rod 16 and the socket 22, and preventing loosening.

[0027] Installation and positioning of curtain wall panel 7: Insert curtain wall panel 7 into the groove 61 of wall panel frame 21 until curtain wall panel 7 is completely embedded in the groove 61; at this time, the four corners of curtain wall panel 7 are respectively embedded into the plate openings 62 of two docking sockets 22. Through the double limiting of the groove 61 and the plate openings 62, the curtain wall panel 7 is stably installed, preventing it from shifting or falling off during use. At the same time, it ensures that the gaps between curtain wall panels 7 are uniform, improving the overall fireproof sealing and aesthetics.

[0028] It enables rapid assembly of frame unit 2 and adapter unit 1 and precise installation of curtain wall panel 7, with reliable connection of each component, meeting the structural strength and usage requirements of fireproof curtain wall.

[0029] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0030] First, the adapter unit 1 is inserted and screwed into the mounting threaded hole 5 by the first bolt 3, and the mating seat 11 is assembled relative to each other; Assembly of frame unit 2: The socket 22 is tilted and fitted against one end of the wall panel frame 21, aligning the plate opening 62 with one of the plate grooves 61 of the wall panel frame 21; the second bolt 23 is countersunk through the middle of the socket 22 and screwed into one end of the wall panel frame 21, then tightened to fix the socket 22 to the wall panel frame 21; at this time, the head of the second bolt 23 is recessed into the socket 22 to ensure a flat surface; one end of each of the two wall panel frames 21 is fitted together at a right angle, so that their respective sockets 22 fit together, and the plate openings 62 of the two sockets 22 fit together to form a right-angle connecting structure; the other end of the fitted socket 22 is inserted into the slot 42 of the adapter unit 1, and the outer wall of the socket 22 fits tightly against the fitting opening 41 and the inner wall of the slot 42 of the adapter unit 1, achieving seamless insertion; When the adapter unit 1 and the frame unit 2 are locked: the locking bolt 12 is rotated clockwise to screw it into the countersunk locking threaded hole 43, which drives the top seat 14 to move backward along the slide rod 13. When the locking bolt 12 rotates, the locking bolt 12 is movably connected to the top seat 14 by means of the bearing 15. The inclined wall of the top seat 14 pushes the force plate 17 to move upward. The force plate 17 drives the locking rod 16 to extend towards the slot 42, thereby driving the locking rod 16 in the two corresponding slots 42 on the docking seat 11 to extend out and insert into the corresponding hole of the socket 22 to achieve locking and fixing. At this time, the spring 18 is compressed, storing elastic potential energy to prevent the locking bolt 12 from rotating due to vibration; When the frame unit 2 is connected to form a cross-shaped connection through the adapter unit 1, the wall panel frame 21 can be relatively fitted to form a frame structure by means of the splicing and assembly of the adapter unit 1. The curtain wall panel 7 can then be inserted into the panel groove 61. The four corners of the curtain wall panel 7 can be fitted without obstruction by means of the fitting of the panel opening 62. The upper and lower sides and the left and right sides of the curtain wall panel 7 are also locked by means of the panel groove 61. The stop cap 8 is installed in the countersunk locking thread hole 43 to cover and protect the locking bolt 12.
