Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building curtain wall structure, in particular to a modular assembly type curtain wall structure convenient to assemble. BACKGROUND

[0002] As the outer envelope structure of modern buildings, curtain walls not only bear the function of architectural aesthetic expression, but also need to have good safety, sealing, durability and construction convenience. The installation and construction of traditional curtain wall structure, especially frame-supported curtain wall, usually relies on a large number of on-site measurement, cutting, welding and punching operations. Specifically, the support framework (such as columns and beams) needs to be aligned one by one and temporarily fixed on site, and then permanently connected by welding or a large number of bolts. This process not only requires high technical level of construction personnel, but also has long construction period, is greatly affected by weather and other site environmental factors, and the construction quality is also difficult to maintain uniformity.

[0003] With the development of building industrialization, prefabricated curtain wall technology emerges as the times require, aiming to improve efficiency and quality through factory prefabrication and on-site assembly. Some existing modular curtain wall solutions have reduced the amount of on-site work to some extent, but still have some limitations.

[0004] The existing solutions use complex connecting components that require multiple special tools for installation. The connection between the support frame and the curtain wall panel usually uses rigid pressing plates or screws for direct fixation, lacking effective buffering mechanism. When subjected to wind load, temperature stress or slight vibration, it is easy to cause stress concentration of the panel or premature failure of the sealing material at the joint. SUMMARY

[0005] In view of the above problems, the present application provides a modular assembly type curtain wall structure convenient to assemble, which is stable and reliable in connection, has good buffering and adjusting capacity, and is easy to maintain and replace.

[0006] The technical scheme of the present application: a modular assembly type curtain wall structure convenient to assemble, comprising a curtain wall panel, a plurality of support frames for clamping the curtain wall panel, and a fixed connection clamping piece for connecting two adjacent support frames; The support frame comprises a horizontal clamping strip with a first through hole at the center, a vertical clamping strip penetrating through the through hole and connected with the horizontal clamping strip by a fastening bolt, a first limiting frame connected with the horizontal clamping strip, and a second limiting frame connected with the vertical clamping strip; The upper and lower ends of the horizontal clamping strip located on both sides of the through hole are respectively provided with transverse clamping grooves, the left and right sides of the vertical clamping strip are respectively provided with vertical clamping grooves, and the center of the vertical clamping strip is provided with a second through hole; The horizontal clamping strip and the vertical clamping strip are both hollow structures, the rear side wall of the horizontal clamping strip is provided with a horizontal limiting gap penetrating the transverse clamping groove along the length direction of the horizontal clamping strip, and the rear side wall of the vertical clamping strip is provided with a vertical limiting gap along the length direction of the vertical clamping strip; The front side of the first limiting frame extends to the inside of the horizontal clamping strip through the horizontal limiting gap, the height of the rear side of the first limiting frame is greater than the height of the horizontal clamping strip, and the two ends of the rear side wall of the first limiting frame are provided with first buffer cushions abutting the surface of the curtain wall panel. The front side of the second limiting frame extends to the inside of the vertical clamping strip through the vertical limiting gap, the width of the rear side of the second limiting frame is greater than the width of the vertical clamping strip, and the two ends of the rear side wall of the second limiting frame are respectively provided with second buffer cushions abutting the surface of the curtain wall panel. The fixed connection clamping piece is used for connecting two adjacent horizontal clamping strips or two adjacent vertical clamping strips.

[0007] Further, the front and rear sides of the transverse clamping groove and the vertical clamping groove are provided with clamping strips connected by a plurality of micro springs, the outer wall of the horizontal clamping strip is provided with a plurality of fastening bolts penetrating into the inside of the transverse clamping groove, and the outer wall of the vertical clamping strip is provided with a plurality of fastening bolts penetrating into the inside of the vertical clamping groove.

[0008] Description: The micro springs in the transverse clamping groove and the vertical clamping groove and the clamping strips constitute an elastic clamping mechanism, after the edge of the curtain wall panel is inserted into the transverse clamping groove or the vertical clamping groove during assembly, the micro springs are compressed to generate a continuous elastic force, so that the clamping strips are tightly abutted against the edge of the curtain wall panel, the size deviation of ±0.5mm of the panel thickness can be self-adapted, slight vibration during transportation or installation is buffered, and hard contact damage of the curtain wall panel with the transverse clamping groove or the vertical clamping groove is prevented; the fastening bolts are screwed in after the elastic clamping is completed, the end of the fastening bolt abuts against the clamping strip, the elastic clamping is converted into rigid locking, and it is ensured that the curtain wall panel will not be displaced due to factors such as wind force and temperature deformation in long-term use.

[0009] Further, the first limiting frame comprises a first inner limiting strip which can penetrate from one side of the horizontal clamping strip and extend to the inside thereof through the second through hole, a first connecting strip which is vertically connected to one end of the first inner limiting strip and extends to the outside through the horizontal limiting gap, and a first outer limiting strip which is abutted against the rear side wall of the horizontal clamping strip and is vertically connected to the first connecting strip, the height of the first outer limiting strip is greater than the height of the horizontal clamping strip, and the first buffer cushion is arranged on the side wall of the first outer limiting strip.

[0010] Instructions: When clamping and fixing the curtain wall panel, firstly, place the curtain wall panel into the horizontal slot. While the horizontal slot limits its position, the first buffer pad on the side wall of the first outer limiting strip adheres to the surface of the curtain wall panel for further limiting. At the same time, since the height of the first outer limiting strip is greater than the height of the horizontal locking strip, the contact area with the rear side wall of the curtain wall panel can be increased, which can significantly improve the wind resistance and deformation resistance of the curtain wall panel and enhance the safety and reliability of the overall system. The first inner limiting strip is made of 6063-T5 aluminum alloy with a rectangular cross-section. Its length is adapted to the span of the horizontal locking strip. After passing through the horizontal locking strip, it extends through the second through-hole of the vertical locking strip, which can simultaneously pass through the intersection area of ​​the horizontal and vertical locking strips, forming a linkage limiting at the "horizontal-vertical" intersection point to prevent relative slippage between the two and improve the overall rigidity of the supporting frame.

[0011] Furthermore, the outer wall of the first inner limiting strip is uniformly provided with several first elastic positioning protrusions, and the inner wall of the horizontal locking strip is provided with first positioning grooves that correspond one-to-one with the first elastic positioning protrusions.

[0012] Description: The first elastic positioning protrusion is integrally injection molded from TPU elastic plastic onto the outer wall of the first inner limiting strip, corresponding one-to-one with the first positioning groove on the inner wall of the horizontal locking strip. During assembly, as the first inner limiting strip is inserted into the horizontal locking strip, the first elastic positioning protrusion is compressed and contracts. When it moves to the position of the first positioning groove, the first elastic positioning protrusion rebounds and locks into the first positioning groove under its own elasticity, realizing the rapid pre-fixation of the first limiting frame. Initial positioning can be completed without additional tools, simplifying the installation process and improving assembly efficiency. This structure also has an anti-detachment function, and after pre-fixation, the first limiting frame will not slip due to gravity or slight collision.

[0013] Furthermore, the second limiting frame includes a second inner limiting strip that can be inserted into the vertical locking strip, a second connecting strip with one end perpendicularly connected to the second inner limiting strip and the other end extending to the outside through the vertical limiting notch, and a second outer limiting strip that fits against the rear side wall of the vertical locking strip and is perpendicularly connected to the second connecting strip. The width of the second outer limiting strip is greater than the width of the vertical locking strip, and the second buffer pad is disposed on the side wall of the second outer limiting strip.

[0014] Instructions: When clamping and fixing the curtain wall panel, first, place the curtain wall panel into the vertical slot. While the vertical slot limits the position, the second buffer pad on the side wall of the second outer limiting strip adheres to the surface of the curtain wall panel for further limiting. At the same time, since the width of the second outer limiting strip is greater than the height of the vertical locking strip, the contact area with the rear side wall of the curtain wall panel can be increased, which can significantly improve the wind resistance and deformation resistance of the curtain wall panel and enhance the safety and reliability of the overall system.

[0015] Furthermore, the outer wall of the second inner limiting strip is uniformly provided with several second elastic positioning protrusions, and the inner wall of the vertical snap-fit ​​strip is provided with second positioning grooves that correspond one-to-one with the second elastic positioning protrusions.

[0016] Description: The second elastic positioning protrusion is integrally injection molded onto the outer wall of the second inner limiting strip, corresponding one-to-one with the second positioning groove on the inner wall of the vertical locking strip. During assembly, as the second inner limiting strip is inserted into the vertical locking strip, the second elastic positioning protrusion is compressed and contracts. When it moves to the position of the second positioning groove, the second elastic positioning protrusion rebounds and locks into the second positioning groove under its own elasticity, realizing the rapid pre-fixation of the second limiting frame. Initial positioning can be completed without additional tools, simplifying the installation process and improving assembly efficiency. This structure also has an anti-detachment function, and after pre-fixation, the second limiting frame will not slip due to gravity or slight collision.

[0017] Furthermore, the fixed connection clip includes a main connecting seat and insertion ports at both ends of the main connecting seat. Each insertion port is fixedly connected to the horizontal or vertical locking strip by a fastening bolt.

[0018] Note: When connecting two adjacent horizontal locking strips, insert the two horizontal locking strips into the interlocking holes at both ends respectively. No on-site welding is required. The frame splicing can be completed by simply tightening the bolts. The same applies when connecting two adjacent vertical locking strips. This enables modular assembly and improves the standardization and efficiency of curtain wall installation.

[0019] Furthermore, the main connecting seat is a hollow structure, and a fixed sleeve is fixedly installed inside the hollow structure, which is directly opposite to each of the insertion ports. The inner wall of the fixed sleeve is provided with a magnet, and the two fixed sleeves are connected by an elastic rod.

[0020] Explanation: The fixing sleeve inside the hollow cavity is aligned with the insertion port, providing guidance and support for the fastening bolts, preventing them from tilting when screwed in, and ensuring uniform transmission of locking force. At the same time, the magnets facilitate the adsorption and positioning of the ends of the horizontal and vertical locking strips, thus preventing the fastening bolts from tilting when screwed in and ensuring uniform transmission of locking force. The elastic rod can absorb part of the impact energy through its own elastic deformation when the curtain wall panel is subjected to external forces such as wind and earthquakes, avoiding stress concentration caused by rigid connections of the main connecting seat, horizontal locking strip, or vertical locking strip, and improving the wind load resistance of the curtain wall panel.

[0021] Furthermore, the curtain wall panel is a glass panel, a stone panel, or a metal composite panel, and the inner surface of the curtain wall panel is provided with a heat-insulating coating.

[0022] Note: The glass panels are made of double-glazed laminated glass, suitable for buildings with high light transmittance requirements; the stone panels are made of granite or marble, suitable for building facades that pursue texture; the metal composite panels are made of aluminum-plastic composite panels, suitable for scenarios that require lightweighting and varied shapes. All three materials can be reliably fixed through this curtain wall structure, expanding the application range of the technical solution. The heat insulation coating effectively blocks the transfer of heat between indoors and outdoors, reducing outdoor heat entering the room in summer and reducing indoor heat loss in winter.

[0023] The beneficial effects of this invention are: The modular prefabricated curtain wall structure of this invention features convenient assembly. In use, horizontal and vertical locking strips interlock to form the basic grid of the support frame. Adjacent support frames are bolted together using fixed connecting clips. Buffer pads on the rear sides of the first and second limiting frames provide flexible contact after the curtain wall panels are installed, preventing damage from hard impacts. The modular design allows for flexible adjustment of the support frame according to the curtain wall size. The slot structure of the horizontal and vertical locking strips is compatible with panels of different thicknesses. Simultaneously, it significantly reduces traditional on-site welding and drilling operations, supporting rapid assembly and positioning. In case of partial damage, individual panels or support units can be disassembled and replaced without dismantling the entire curtain wall, resulting in low maintenance costs and no impact on the surrounding structure. All connection points are hidden inside the slots or frames, with no exposed bolts or welds on the curtain wall surface, resulting in a clean and aesthetically pleasing appearance. This curtain wall structure, through its ingenious modular and locking design, achieves a comprehensive improvement in installation efficiency, structural performance, maintenance convenience, and economy, making it suitable for various modern building curtain wall projects.

Detailed Implementation

[0026] Example 1 like Figure 1 As shown, a modular prefabricated curtain wall structure that is easy to assemble includes a curtain wall panel 1, 16 support frames 2 for engaging the curtain wall panel 1, and a fixing fastener 3 for connecting two adjacent support frames 2. The curtain wall panel 1 adopts existing technologies, such as glass panels, stone panels, or metal composite panels. The inner surface of the curtain wall panel 1 is equipped with a heat insulation coating. The glass panel uses double-layer hollow laminated glass, which is suitable for buildings with high light transmission requirements. The stone panel uses granite or marble, which is suitable for building facades that pursue texture. The metal composite panel uses aluminum-plastic composite panels, which is suitable for scenarios that require lightweighting and varied shapes. All three materials can be reliably fixed through this curtain wall structure, which expands the application range of the technical solution. The heat insulation coating uses a Low-E low-emissivity coating with an emissivity ≤0.15, which effectively blocks the transfer of heat between indoors and outdoors, reducing the entry of outdoor heat into the room in summer and reducing the loss of indoor heat in winter. The support frame 2 includes a horizontal locking strip 21 with a first through-hole 20 at the center, a vertical locking strip 22 that passes through the through-hole 20 and is connected to the horizontal locking strip 21 by fastening bolts, a first limiting frame 23 connected to the horizontal locking strip 21, and a second limiting frame 24 connected to the vertical locking strip 22. The horizontal snap-fit ​​strip 21 has horizontal snap-fit ​​grooves 210 at the top and bottom ends on both sides of the through opening 20, and the vertical snap-fit ​​strip 22 has vertical snap-fit ​​grooves 220 on both the left and right sides, and a second through opening 221 at the center of the vertical snap-fit ​​strip 22. Both the horizontal locking strip 21 and the vertical locking strip 22 are hollow structures. The rear side wall of the horizontal locking strip 21 is provided with a horizontal limiting notch 211 that communicates with the transverse locking groove 210 along its length direction. The rear side wall of the vertical locking strip 22 is provided with a vertical limiting notch 25 along its length direction. The front side of the first limiting frame 23 extends into the interior of the horizontal locking strip 21 through the horizontal limiting notch 211. The height of the rear side of the first limiting frame 23 is 1.5 times the height of the horizontal locking strip 21. The two ends of the rear side wall of the first limiting frame 23 are provided with first buffer pads 230 that are in contact with the surface of the curtain wall panel 1. The first buffer pads 230 adopt existing technology, such as PU foam rubber. like Figure 4 As shown, the first limiting frame 23 includes a first inner limiting strip 231 that can be inserted from one side of the horizontal locking strip 21 and extend into it through the second through-hole 221; a first connecting strip 232 whose one end is perpendicularly connected to the first inner limiting strip 231 and whose other end extends to the outside through the horizontal limiting notch 211; and a first outer limiting strip 233 that is fitted to the rear side wall of the horizontal locking strip 21 and perpendicularly connected to the first connecting strip 232. The height of the first outer limiting strip 233 is greater than the height of the horizontal locking strip 21. A first buffer pad 230 is disposed on the side wall of the first outer limiting strip 233. When clamping and fixing the curtain wall panel 1, firstly, the curtain wall panel 1 is placed into the horizontal locking groove 210. While being limited by the horizontal locking groove 210, the first outer limiting strip 233 is also used for clamping and fixing. The first buffer pad 230 fits and limits the surface of the curtain wall panel 1. At the same time, since the height of the first outer limiting strip 233 is greater than the height of the horizontal locking strip 21, the contact area with the rear side wall of the curtain wall panel 1 can be increased, which can significantly improve the wind resistance and deformation resistance of the curtain wall panel 1 and enhance the safety and reliability of the overall system. The first inner limiting strip 231 is made of 6063-T5 aluminum alloy with a rectangular cross section. Its length is adapted to the span of the horizontal locking strip 21. After passing through the horizontal locking strip 21, it extends through the second through-hole 221 of the vertical locking strip 22. It can simultaneously pass through the intersection area of ​​the horizontal locking strip 21 and the vertical locking strip 22 to form a linkage limiting at the "horizontal-vertical" intersection point, preventing the two from sliding relative to each other and improving the overall rigidity of the support frame 2. like Figure 3As shown, the outer wall of the first inner limiting strip 231 is uniformly provided with 20 first elastic positioning protrusions 234, and the inner wall of the horizontal locking strip 21 is provided with first positioning grooves 214 corresponding one-to-one with the first elastic positioning protrusions 234. The first elastic positioning protrusions 234 are integrally injection molded from TPU elastic plastic onto the outer wall of the first inner limiting strip 231, corresponding one-to-one with the first positioning grooves 214 on the inner wall of the horizontal locking strip 21. During assembly, as the first inner limiting strip 231 is inserted into the horizontal locking strip 21, the first elastic positioning protrusions 234... 4. When compressed and contracted, the first elastic positioning protrusion 234 rebounds and locks into the first positioning groove 214 under its own elasticity when it moves to the position of the first positioning groove 214, realizing the rapid pre-fixation of the first limiting frame 23. The initial positioning can be completed without additional tools, simplifying the installation process and improving assembly efficiency. The structure also has an anti-detachment function. After pre-fixation, the first limiting frame 23 will not slip due to gravity or slight collision. The first elastic positioning protrusion 234 adopts existing technology, such as silicone rubber. The front side of the second limiting frame 24 extends into the interior of the vertical locking strip 22 through the vertical limiting notch 25. The width of the rear side of the second limiting frame 24 is 1.5 times the width of the vertical locking strip 22. The two ends of the rear side wall of the second limiting frame 24 are respectively provided with second buffer pads 240 that are in contact with the surface of the curtain wall panel 1. The second buffer pads 240 adopt existing technology, such as PU foam rubber. like Figure 5 As shown, the second limiting frame 24 includes a second inner limiting strip 241 that can be inserted into the vertical locking strip 22, a second connecting strip 242 whose one end is perpendicularly connected to the second inner limiting strip 241 and whose other end extends to the outside through the vertical limiting notch 25, and a second outer limiting strip 243 that is fitted to the rear side wall of the vertical locking strip 22 and perpendicularly connected to the second connecting strip 242. The width of the second outer limiting strip 243 is greater than the width of the vertical locking strip 22. A second buffer pad 240 is provided on the side wall of the second outer limiting strip 243 to support the curtain wall. When clamping and fixing panel 1, firstly, the curtain wall panel 1 is placed into the vertical slot 220. While the vertical slot 220 limits the position, the second buffer pad 240 on the side wall of the second outer limiting strip 243 fits and limits the position against the surface of the curtain wall panel 1. At the same time, since the width of the second outer limiting strip 243 is greater than the height of the vertical locking strip 22, the contact area with the rear side wall of the curtain wall panel 1 can be increased, which can significantly improve the wind resistance and deformation resistance of the curtain wall panel 1 and enhance the safety and reliability of the overall system. The outer wall of the second inner limiting strip 241 is uniformly provided with 20 second elastic positioning protrusions 244, and the inner wall of the vertical snap-fit ​​strip 22 is provided with second positioning grooves 215 corresponding one-to-one with the second elastic positioning protrusions 244. The second elastic positioning protrusions 244 adopt existing technology, such as silicone rubber. like Figure 6As shown, the fixed connecting clip 3 is used to connect two adjacent horizontal clips 21 or two adjacent vertical clips 22. The fixed connecting clip 3 includes a main connecting seat 30 and insertion ports 31 located at both ends of the main connecting seat 30. Each insertion port 31 is fixedly connected to the horizontal clip 21 or the vertical clip 22 by fastening bolts. When connecting two adjacent horizontal clips 21, the two horizontal clips 21 are inserted into the insertion ports 31 at both ends respectively. No on-site welding is required. The frame splicing can be completed by simply tightening the bolts. The same applies when connecting two adjacent vertical clips 22. Modular assembly can be achieved, which improves the standardization and efficiency of curtain wall installation.

[0027] Example 2 The difference between this embodiment and Embodiment 1 is that: like Figure 7 , 8 As shown, both the front and rear sides of the horizontal slot 210 and the vertical slot 220 are equipped with clamping bars 213 connected by 18 miniature springs 212. Eight fastening bolts penetrating into the horizontal slot 210 are installed on the outer wall of the horizontal clamping bar 21, and eight fastening bolts penetrating into the vertical slot 220 are installed on the outer wall of the vertical clamping bar 22. The miniature springs 212 in the horizontal and vertical slots 210 and the clamping bars 213 form an elastic clamping mechanism. The miniature springs are stainless steel compression springs with an elastic modulus of 0.8-1.2 N / mm, and the clamping bars 213 are made of nylon with a Shore hardness of 60-70. During assembly, the curtain wall panel... After the edge is inserted into the horizontal slot 210 or the vertical slot 220, the micro spring 212 is compressed to generate a continuous elastic force, which makes the clamping strip 213 fit tightly against the edge of the curtain wall panel 1. It can adapt to the dimensional deviation of the panel thickness ±0.5mm, and at the same time buffer the slight vibration during transportation or installation, preventing the curtain wall panel 1 from being damaged by hard contact with the horizontal slot 210 or the vertical slot 220. The fastening bolt is an M6×12 type stainless steel hexagonal bolt, which is screwed in after the elastic clamping is completed. The end of the fastening bolt presses against the clamping strip 213, converting the elastic clamping into rigid locking, ensuring that the curtain wall panel 1 will not be displaced due to wind, temperature deformation or other factors during long-term use. The main connecting seat 30 has a hollow structure, and a fixing sleeve 32 is fixedly installed inside the hollow structure, which is directly opposite to each insertion port 31. The inner wall of the fixing sleeve 32 is provided with a magnet 33. Two fixing sleeves 32 are connected by an elastic rod 320. The fixing sleeves 32 inside the hollow cavity are directly opposite the insertion ports 31, providing guidance and support for the fastening bolts, preventing misalignment when the bolts are tightened, and ensuring uniform transmission of locking force. At the same time, the magnet 33 facilitates the attraction and positioning of the ends of the horizontal locking strip 21 and the vertical locking strip 22, thereby ensuring... To prevent misalignment when tightening the bolts and ensure uniform transmission of locking force, the elastic rod 320 is made of stainless steel spring steel with an elastic coefficient of 1.5-2.0 N / mm. When the curtain wall panel 1 is subjected to external forces such as wind and earthquakes, it can absorb part of the impact energy through its own elastic deformation, avoiding stress concentration caused by rigid connection of the main connecting seat 30, horizontal locking strip 21 or vertical locking strip 22, and improving the wind load resistance of the curtain wall panel 1. The magnet 33 adopts existing technology, such as neodymium iron boron permanent magnet.

[0028] When using the modular prefabricated curtain wall structure of this embodiment, the following steps are included: S1, the horizontal locking strip 21 and the vertical locking strip 22 are cross-fixed. The horizontal locking strip 21 has a first through-hole 20 at its center. After the vertical locking strip 22 passes through the first through-hole 20, the two are locked together by fastening bolts to form a cross-shaped basic support unit. The second through-hole 221 of the vertical locking strip 22 provides a channel for the insertion of the first limiting frame 23, so as to realize the linkage limiting of the horizontal locking strip 21 and the vertical locking strip 22. S2. When installing the first limiting frame 23, the first inner limiting strip 231 is inserted from one side of the horizontal locking strip 21 and extends through the second through-hole 221 of the vertical locking strip 22 to the other side of the horizontal locking strip 21. During the insertion process, the first elastic positioning protrusion 234 on the outer wall of the first inner limiting strip 231 is squeezed and contracted by the inner wall of the horizontal locking strip 21. When it moves to the position corresponding to the first positioning groove 214, the first elastic positioning protrusion 234 rebounds and locks into the first positioning groove 214, completing the quick pre-fixing of the first limiting frame 23. Its axial sliding can be restricted without additional tools. The first outer limiting strip 233 is linked with the first inner limiting strip 231 through the first connecting strip 232, forming an inner-outer double limiting for the curtain wall panel 1. S3. The second inner limiting strip 241 is inserted into the vertical snap-fit ​​strip 22 and pre-fixed by snap-fitting the second elastic positioning protrusion 244 and the second positioning groove 215. The second outer limiting strip 243 fits against the rear side wall of the vertical snap-fit ​​strip 22 and forms a "cross-shaped" curtain wall panel 1 support system with the first outer limiting strip 233. S4. The height of the first outer limiting strip 233 is greater than that of the horizontal locking strip 21, and the width of the second outer limiting strip 243 is greater than that of the vertical locking strip 22, which can increase the contact area with the rear side wall of the curtain wall panel 1. At the same time, the first buffer pad 230 and the second buffer pad 240 directly adhere to the surface of the curtain wall panel 1, which not only avoids scratches caused by hard contact between metal and the curtain wall panel 1, but also fills the assembly gap through micro-elastic deformation. S5. Insert the edge of the curtain wall panel 1 into the horizontal slot 210 of the horizontal locking strip 21 or the vertical slot 220 of the vertical locking strip 22 to achieve the initial circumferential positioning of the curtain wall panel 1. S7. The miniature spring 212 in the horizontal slot 210 / vertical slot 220 and the clamping strip 213 form an elastic clamping mechanism. When the curtain wall panel 1 is inserted into the horizontal slot 210 / vertical slot 220, it squeezes the clamping strip 213. The miniature spring 212 is compressed and generates a continuous elastic restoring force, so that the clamping strip 213 fits tightly against the edge of the curtain wall panel 1. Then, the fastening bolt is tightened to make it press against the clamping strip 213, converting the elastic clamping into rigid locking, restricting the longitudinal displacement of the curtain wall panel 1, and coping with external forces such as wind and temperature deformation during long-term use. S8. When connecting two adjacent horizontal connecting strips 21, insert the two horizontal connecting strips 21 into the insertion ports 31 at both ends respectively, and tighten them with bolts to complete the frame splicing. When connecting two adjacent vertical connecting strips 22, insert the two vertical connecting strips 22 into the insertion ports 31 at the top and bottom ends respectively.
