Description

Technical Field

[0001] This invention relates to the field of building curtain wall and window technology, and in particular to the coplanar connection structure of interlayer panels and large panel panels in window wall systems. Background Technology

[0002] The external envelope of modern mid- to high-rise buildings mainly adopts two categories: curtain wall systems and window-wall systems. As a structurally independent, non-load-bearing external envelope, the curtain wall system is suspended outside the main building structure and usually spans multiple floors. It is anchored to the edge of the floor slab through connectors, which can achieve a continuous and smooth building facade effect, while also having good airtightness and watertightness. It is widely used in large public buildings and high-rise office buildings. The window-wall system, on the other hand, is an envelope structure that spans only a single floor. Its upper and lower ends are supported by the upper and lower surfaces of the floor slab, respectively, and it is installed on the inner side of the floor slab edge. It can be installed entirely from the interior side without the need for large high-altitude equipment. Moreover, the floor slab naturally forms a fire compartment without the need for additional sealing, and it also has superior floor sound insulation performance.

[0003] The existing conventional window-wall system frame needs to be fixed between the upper and lower floor slabs. In the inter-floor area corresponding to the edge of the floor slab, an independent covering component is usually required to cover the floor slab and internal connecting structure. Some technologies in the industry have attempted to solve the problem of uneven facade of window-wall system. This is mainly done by setting up detachable floor slab edge covering components and matching them with on-site adjustment mechanisms to adjust the installation position of the covering components so that they are aligned as much as possible with the adjacent large glass panels. This weakens the horizontal unevenness of the facade and improves the overall visual effect of the building facade.

[0004] Such solutions have unavoidable systemic defects in practical engineering applications. The on-site adjustment process is highly dependent on the operational skills of the construction personnel. In large-scale batch construction scenarios, the difference in adjustment accuracy among different operators will lead to uneven facade flatness. Moreover, the block-by-block adjustment method greatly increases the workload of on-site construction and prolongs the construction cycle. At the same time, the setting of the adjustment mechanism will make the overall structure more complex, which will not only increase material and processing costs, but also increase the difficulty of later maintenance. It is impossible to balance construction efficiency, cost control and facade stability, and it is difficult to meet the dual requirements of modern buildings for efficient construction and aesthetic appearance of window and wall systems. Summary of the Invention

[0005] The purpose of this invention is to provide a coplanar connection structure between interlayer panels and large panel panels in a window-wall system, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides a coplanar connection structure for interlayer panels and large panel panels in a window-wall system, including an upper floor slab, a lower floor slab, an upper window sleeve, and a lower window sleeve. The lower surface of the upper floor slab is fixedly installed with the upper window sleeve by anchors. The lower part of the upper window sleeve is integrally connected with an upper track profile. The lower part of the upper track profile has interlayer panel slots and large panel upper slots arranged side by side in the horizontal direction. The upper surface of the lower floor slab is fixedly installed with the lower window sleeve by anchors. The upper part of the lower window sleeve is integrally connected with a lower track profile. The upper part of the lower track profile has interlayer panel fixing surfaces and large panel lower clips arranged side by side in the horizontal direction. It also includes the interlayer panel body and the large panel body. The interlayer panel body includes an interlayer frame and an interlayer panel. The interlayer panel is installed on the outside of the interlayer frame. The upper end of the interlayer frame is fixed with an upper hook and the lower end is fixed with a lower fixing surface. The upper hook is hooked into the interlayer panel slot. The lower fixing surface rests on and is fixed to the interlayer panel fixing surface. The large panel body includes a large panel frame and a large panel. The large panel is installed on the outside of the large panel frame. The upper end of the large panel frame is fixed with an upper insertion part and the lower end is fixed with a lower insertion part. The upper insertion part is inserted into the upper slot of the large panel, and the lower insertion part is inserted into the lower clip of the large panel. The relative position of the slot and the fixing surface is determined by the profile precision. After assembly, the two panels are automatically coplanar and do not require on-site adjustment.

[0007] Furthermore, a continuous waterproof pad is laid between the top of the upper window frame and the upper floor slab, and between the bottom of the lower window frame and the lower floor slab. Both the upper and lower window frames are integral extruded aluminum alloy profiles, and their tracks, slots, and fixing surfaces are formed in one piece using the same mold.

[0008] Furthermore, a sealing strip extending horizontally is embedded between the upper end of the large frame and the upper track profile, and between the lower end of the large frame and the lower track profile. The sealing strip is compressed within the contact gap between adjacent components.

[0009] Furthermore, a lower edge protector of a large panel block is fixedly installed on the lower outer side of the large surface frame, and an upper edge protector of a large panel block is fixedly installed on the upper outer side of the large surface frame. The lower edge protector of the large panel block extends toward the upper end of the interlayer panel body, and the upper edge protector of the large panel block extends toward the lower end of the interlayer panel body.

[0010] Furthermore, a first waterproof strip and a second waterproof strip are sequentially embedded at the bottom of the lower edge of the large panel block, and a first waterproof strip and a second waterproof strip are sequentially embedded at the bottom of the upper track profile. The first waterproof strip and the second waterproof strip overlap the surfaces of the upper fixing surface and the upper edge of the large panel block, respectively.

[0011] Furthermore, an independent drainage channel is formed at the horizontal joint between the interlayer frame and the main frame, which is arranged along the horizontal direction. The drainage channel is located inside the first waterproof strip, and its outlet leads to the exterior facade of the building.

[0012] Furthermore, the bottom of the interlayer plate slot is provided with interlayer plate slot drainage holes arranged at intervals in the horizontal direction, and the water accumulated in the interlayer plate slot flows into the drainage channel through the slot drainage holes.

[0013] Furthermore, a drainage groove is provided at the lower outer end of the drainage channel, and a self-draining mechanism is provided on the inner side of the drainage groove.

[0014] Furthermore, the self-draining mechanism includes a side sleeve, which is fixedly connected to both sides of the drainage channel. A torsion spring is fixedly connected to the inner side of the side sleeve, and a turntable is fixedly connected to the inner side of the torsion spring. The turntable is rotatably connected to the inner end of the side sleeve, and a dust baffle 304 is fixedly connected between the inner sides of the turntable. The dust baffle 304 covers the outer side of the drainage channel 29. The inner wall of the drainage channel 29 is provided with a limiting protrusion to prevent the dust baffle 304 from flipping inward. During use, when there is water accumulation inside the drainage channel, the water pressure will press the dust baffle outward. The dust baffle can drain the water by rotating outward appropriately. Under the action of external wind pressure, the dust baffle abuts against the limiting protrusion and remains closed. After the water is completely drained, the torsion spring resets and can cover and fill the drainage channel again, thereby avoiding the problem of the drainage channel being exposed, causing dust or harmful insects to enter the drainage channel and block it.

[0015] Furthermore, the sealing strip has a concave cross-sectional shape, and the two sides of the sealing strip are linearly arranged with equal spacing and integrally formed with support strips.

[0016] Compared with the prior art, the beneficial effects of the present invention are: In this invention, by setting up an integrally formed upper and lower window frame structure, the relative positions of the slot and the fixing surface can be determined during the factory production stage. On-site measurement and adjustment of the installation benchmark are unnecessary. Construction workers only need to hang or insert the prefabricated panels into the designated positions to complete the main assembly. All processes can be completed indoors, without the need for large-scale high-altitude work equipment. The construction process is unaffected by outdoor weather conditions, shortening the overall construction cycle, reducing safety risks during construction, and lowering the rental and usage costs of large equipment. By setting up a multi-layered waterproof and drainage structure, rainwater can be blocked by multiple layers of rubber strips, and a small amount of seeping water can be contained. The building is drained through a dedicated channel. The self-draining mechanism automatically seals the drain outlet after drainage to prevent debris from entering and causing blockages. The single-layer partition structure allows the floor slabs to naturally form fire-resistant zones without the need for additional inter-floor fire-resistant sealing structures. Various building materials can be selected for the inter-floor panels to suit different building facade design requirements. Through the cooperation of window frame profiles and panel hook-and-loop structures, the inter-floor panels and the main panels can be kept in the same vertical plane. At the same time, it retains the construction and fire-resistant advantages of traditional window-wall systems, makes up for the shortcomings of existing technologies, and achieves a continuous and flat building facade effect while controlling construction costs and safety risks.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 7 In this embodiment of the invention, the coplanar connection structure of the interlayer panels and the large panel of the window wall system includes an upper floor slab 1, a lower floor slab 2, an upper window sleeve 3 and a lower window sleeve 7. The lower surface of the upper floor slab 1 is fixedly installed with the upper window sleeve 3 by anchors. The lower part of the upper window sleeve 3 is integrally connected with an upper track profile 4. The lower part of the upper track profile 4 is provided with interlayer panel slots 5 and large panel upper slots 6 arranged side by side in the horizontal direction. The upper surface of the lower floor slab 2 is fixedly installed with the lower window sleeve 7 by anchors. The upper part of the lower window sleeve 7 is integrally connected with a lower track profile 8. The upper part of the lower track profile 8 is provided with interlayer panel fixing surfaces 9 and large panel lower clips 10 arranged side by side in the horizontal direction. It also includes an interlayer panel body 11 and a large panel body 16. The interlayer panel body 11 includes an interlayer frame 13 and an interlayer panel 12. The upper end of the interlayer frame 13 is fixed with an upper hook 14, and the lower end is fixed with a lower fixing surface 15. The upper hook 14 is hooked into the interlayer panel slot 5. The lower fixing surface 15 rests on and is fixed to the interlayer panel fixing surface 9. The large panel body... 16 includes a large frame 18 and a large panel 17. The large panel 17 is installed on the outer side of the large frame 18. An upper insertion part 19 is fixed to the upper end of the large frame 18, and a lower insertion part 20 is fixed to the lower end. The upper insertion part 19 is inserted into the upper slot 6 of the large panel, and the lower insertion part 20 is inserted into the lower clip 10 of the large panel. During the application of this device, by setting the upper window sleeve 3 and the lower window sleeve 7 with corresponding slots and clip structures, it is possible to complete the process in sequence during use. The assembly process is completed as a whole. Based on the pre-set installation positions of the upper track profile 4 and the lower track profile 8, the interlayer panel body 11 can be placed and fixed with the lower hook 14 and the upper fixing surface 15. The large panel body 16 can be connected with the upper insertion part 19 and the lower insertion part 20. The entire assembly process can be carried out step by step in an orderly manner. There is no need to adjust the placement of each panel during on-site work, which can reduce the steps of on-site operation. The panels cooperate with each other by snap-fit ​​and hook-fit, which can make the interlayer panel 12 and the large panel 17 form a regular facade shape, and also reduce the extra workload caused by on-site manual operation. The combination of panels and window frames is simple and easy to implement, and ordinary workers can complete the installation work smoothly, further simplifying the overall process of on-site construction. The overall structure formed by the cooperation of panels and window frames can also make the various components fit together tightly, maintaining the overall appearance of the facade.

[0021] Please see Figures 1-2A continuous waterproof pad 23 is laid between the top of the upper window frame 3 and the upper floor slab 1, and between the bottom of the lower window frame 7 and the lower floor slab 2. Both the upper window frame 3 and the lower window frame 7 are integrally extruded aluminum alloy profiles. During the application of this device, by laying a continuous waterproof pad 23 between the upper window frame 3 and the upper floor slab 1, and between the lower window frame 7 and the lower floor slab 2, the gaps at the joints of the components can be covered, preventing external water from seeping into the interior from the joint between the floor slab and the window frame. Combined with the upper window frame 3 and the lower window frame 7, which are integrally extruded aluminum alloy profiles, the window frame itself can be made more robust. The structure remains unified, and the various installation structures attached to the window frame can maintain a fixed shape. During the assembly process with the interlayer panel body 11 and the large panel body 16, there will be no local deformation. It can also keep the fit between the window frame and the floor slab consistent. The waterproof pad 23 can form a continuous barrier area along the extension direction of the window frame, further weakening the impact of gaps. The overall combination can reduce the penetration of water into the building interior and allow the window frame to maintain the preset installation shape for a long time, continuously cooperating with various panels to complete the construction of the facade.

[0022] Please see Figures 1-2 A horizontally extending sealing strip 21 is embedded between the upper end of the large frame 18 and the upper track profile 4, and between the lower end of the large frame 18 and the lower track profile 8. During the application of this device, by embedding the horizontally extending sealing strip 21 between the large frame 18 and the upper track profile 4 and the lower track profile 8, the gap at the connection between the frame and the track profile can be filled during use. External airflow and water flow will not pass inward along the gap between the components. The sealing strip 21 is continuously arranged in the horizontal direction and can completely cover the entire connection area. The mutual compression of the components allows the sealing strip 21 to fully adhere to both sides of the surface, further reducing the gap space and reducing the entry of external substances into the component. The strip cooperates with the surrounding components, which can also make the combination of the large panel body 16 and the upper and lower window frames 7 more tight. During the long-term use of the facade, it continuously plays a blocking role in the connection gap.

[0023] Please see Figures 1-2A lower edge protector 27 for a large panel block is fixedly installed on the lower outer side of the large frame 18, and an upper edge protector 28 for a large panel block is fixedly installed on the upper outer side of the large frame 18. The lower edge protector 27 extends toward the upper end of the interlayer panel body 11, and the upper edge protector 28 extends toward the lower end of the interlayer panel body 11. During the application of this device, by installing the lower edge protector 27 and the upper edge protector 28 for a large panel block on the outer side of the large frame 18, the extended layout of the edges allows for connection of the large panel blocks. At the adjacent positions of the main body 16 and the interlayer main body 11, the protective edge is attached to the joint of the panels along the direction of the component arrangement. It can cover the exposed gap between the two panels. The water flowing from the outside will slide down the surface of the protective edge and will not directly enter the gap between the panels. The protective edge and the panels on both sides fit together, which can also make the joint of each component of the facade more regular. It forms a continuous protective structure along the overall direction of the building facade, and continuously plays a role in shielding and guiding the water flow at the joint of the panels.

[0024] Please see Figures 1-2 The bottom of the lower edge 27 of the large panel is sequentially fitted with a first waterproof strip 24 and a second waterproof strip 25. The bottom of the upper track profile 4 is also sequentially fitted with a first waterproof strip 24 and a second waterproof strip 25. The first waterproof strip 24 and the second waterproof strip 25 overlap the surfaces of the upper fixed surface 15 and the upper edge 28 of the large panel, respectively. During application, by installing the first waterproof strip 24 and the second waterproof strip 25 at the bottom of the lower edge 27 of the large panel and the bottom of the upper track profile 4, this device allows for [the use of...]. Multi-layered adhesive strips form a layered barrier. The strips overlap on the surface of corresponding components, creating a continuous protective area along the joint. Water flowing from top to bottom is blocked layer by layer, significantly reducing the possibility of water entering the joint gaps between the panels. The sequential arrangement of multiple strips can distribute the impact of water flow, avoiding the problem of insufficient protection in a single barrier structure. The strips work in conjunction with edge protection, track profiles, and panel components to ensure that the protection range of each joint is connected, forming a complete shield for the gaps in the facade and continuously reducing the possibility of water seeping into the interior of the components.

[0025] Please see Figures 1-2An independent drainage channel 22 is formed at the horizontal joint between the interlayer frame 13 and the main frame 18, running horizontally. The drainage channel 22 is located inside the first waterproof sealant strip 24, and its outlet leads to the exterior facade of the building. During the application of this device, by setting an independent drainage channel 22 at the horizontal joint between the interlayer frame 13 and the main frame 18, it can receive a small amount of water that seeps in through the outer waterproof structure. The drainage channel 22 is located inside the first waterproof sealant strip 24, which can collect scattered water flow. The channel runs horizontally, which can smoothly collect water from various parts of the joint. The outlet of the channel faces the exterior facade of the building, and the collected water can be discharged directly to the outside, without accumulating in the gaps between components for a long time. The drainage channel 22 and the outer waterproof sealant strip work together to form an internal and external protective form, allowing the infiltrated water flow to be drained away in time, reducing the impact of water accumulation.

[0026] Please see Figures 1-2 The bottom of the interlayer plate slot 5 is provided with interlayer plate slot drainage holes 26 arranged horizontally. Water accumulated in the interlayer plate slot 5 flows into the drainage channel 22 through the slot drainage holes. During the application of this device, by setting the interlayer plate slot drainage holes 26 at the bottom of the interlayer plate slot 5, the water accumulated inside the slot can be drained in time. The drainage holes are arranged horizontally and can cover the entire area of ​​the slot. Water collected in various parts of the slot can flow outward along the drainage holes. The water will flow directly into the adjacent drainage channel 22. The drainage holes and drainage channel 22 are interconnected and cooperate with each other, which can prevent water from remaining inside the slot for a long time, and can also drain water from different locations in a unified manner, reducing the situation of water staying inside the component, and keeping the slot area dry at all times.

[0027] Please see Figures 3-6 A drainage trough 29 is provided at the lower outer end of the drainage channel 22, and a self-draining mechanism 30 is provided on the inner side of the drainage trough 29. During the application of this device, by setting the drainage trough 29 at the lower outer end of the drainage channel 22 and matching the self-draining mechanism 30 on the inner side of the drainage trough 29, it can collect the water transported from inside the channel. After the water flows to the position of the drainage trough 29, it can be discharged outward with the help of the self-draining mechanism 30. The drainage trough 29 is connected to the end of the drainage channel 22 and can collect the water flow transported by the channel. The self-draining mechanism 30 is attached to the inner side of the drainage trough 29 and can complete the opening and closing action according to the water flow status. After the water flow is discharged, it can form a shield for the drainage trough 29 again to prevent external debris from entering the trough. The drainage trough 29 and the self-draining mechanism 30 work together to ensure that the entire drainage line can be smoothly terminated and the drainage channel 22 can be continuously maintained.

[0028] Please see Figures 3-6The self-draining mechanism 30 includes a side sleeve 301, which is fixedly connected to both sides of the drainage trough 29. A torsion spring 302 is fixedly connected to the inner side of the side sleeve 301, and a turntable 303 is fixedly connected to the inner side of the torsion spring 302. The turntable 303 is rotatably connected to the inner end of the side sleeve 301. A dust baffle 304 is fixedly connected between the inner sides of the turntable 303, and the dust baffle 304 covers the outer side of the drainage trough 29. During the application of this device, by installing the side sleeves 301 on both sides of the drainage trough 29, and then relying on the side sleeves 301 in sequence with the torsion spring 302, the turntable 303 and the dust baffle 304, a complete self-draining machine is formed. The structure 30 allows the accumulated water to reach the drainage trough 29 during use, generating force that pushes the dust baffle 304 to rotate the turntable 303, thereby opening the outer area of ​​the drainage trough 29 and allowing the accumulated water to drain out smoothly. After the water flows away, the force generated by the torsion spring 302 will cause the turntable 303 and the dust baffle 304 to return to their original positions, re-blocking the outer opening of the drainage trough 29. External debris and flying insects will not enter the drainage trough 29 through the opening. The entire set of components works together to autonomously complete the drainage and sealing actions, allowing the drainage trough 29 to remain unobstructed for a long time without manual maintenance.

[0029] Please see Figures 3-6 The sealing strip 21 has a concave cross-sectional shape. Supporting strips are integrally formed on both sides of the sealing strip 21, with equal spacing. During application, by setting the sealing strip 21 to a concave cross-section and simultaneously arranging multiple integrally formed supporting strips on both sides, the device can securely fasten the sealing strip 21 to the installation position of the component, preventing displacement or detachment. The concave cross-sectional shape can adapt to the splicing gaps between components, further filling the empty space at the joint. The linear arrangement of the supporting strips at fixed intervals can distribute the compressive force on the strip from multiple points, making the overall force on the strip more balanced. The structure of the strip itself and the additional supporting strips work together to maintain the installation state for a long time, continuously blocking the gaps between components.

[0030] The working principle of this invention is as follows: The upper window sleeve 3 and the lower window sleeve 7 of this technical solution are both made of integral profiles. The interlayer plate slot 5 on the upper track profile 4 and the upper slot 6 on the large panel block, and the interlayer plate fixing surface 9 on the lower track profile 8 and the lower clip head 10 on the large panel block are all formed in one piece by the same extrusion mold. The relative positions between each structure are determined in the factory production stage. On the construction site, it is only necessary to fix the upper window sleeve 3 and the lower window sleeve 7 to the corresponding positions of the upper floor slab 1 and the lower floor slab 2. There is no need to measure and align the positions of the slots and fixing surfaces on site. Differences in the operation of the construction personnel will not affect the final installation effect. Both the interlayer panel body 11 and the large panel body 16 are prefabricated single-layer high window wall units. The lower end of the interlayer frame 13 is prefabricated with a lower hook 14 and the upper end with a upper fixing surface 15. The upper and lower ends of the large panel frame 18 are prefabricated with an upper insertion part 19 and a lower insertion part 20, respectively. During installation, the lower hook 14 is simply hooked into the interlayer panel slot 5, the upper fixing surface 15 is placed and fixed to the interlayer panel fixing surface 9, and then the upper insertion part 19 is inserted into the upper slot 6 of the large panel and the lower insertion part 20 is inserted into the lower clip 10 of the large panel to complete the main assembly. The operation process is simple and intuitive, and can be quickly mastered without complicated technical training. It can significantly shorten the installation time of a single panel and improve the overall construction progress.

[0031] All installation work can be completed inside the building, eliminating the need for workers to perform high-altitude operations outside the building or to use large hoisting equipment such as suspended platforms or aerial work platforms. The construction process is unaffected by outdoor weather conditions such as rain, snow, or strong winds, effectively reducing safety risks and minimizing the rental and use costs of large equipment, thus compressing overall construction costs. This technical solution continues the single-layer partitioned structure of the window-wall system. Both the inter-floor panel body 11 and the large panel body 16 span only a single floor. The upper floor slab 1 and the lower floor slab 2 naturally form a complete fire compartment. There are no continuous cavities between the floor slab edges and the window-wall system, preventing flames and smoke from spreading between floors during a fire. Therefore, no additional inter-floor fire-stopping structure is required, reducing corresponding construction procedures and material inputs.

[0032] This technical solution employs a multi-layered waterproof and drainage structure. The waterproof padding layer 23 laid between the upper window frame 3 and the upper floor slab 1, and between the lower window frame 7 and the lower floor slab 2, seals structural gaps. The sealing strips 21 embedded between the large panel frame 18 and the upper track profile 4, and between the large panel frame 18 and the lower track profile 8, form a continuous airtight and watertight seal. The first waterproof strip 24 and the second waterproof strip 25 installed at the bottom of the large panel edge 27 and the upper track profile 4 prevent most rainwater flowing along the panel surface from entering the joint area. A small amount of rainwater that passes through the waterproof strips will enter the interlayer frame. The drainage channel 22 between the frame 13 and the large frame 18 allows a small amount of water accumulated in the interlayer plate slot 5 to flow into the drainage channel 22 through the drainage hole 26 of the interlayer plate slot at the bottom. After the water collects in the drainage channel 22, it flows to the drainage trough 29 on the outside. The self-draining mechanism 30 set inside the drainage trough 29 can automatically close the outer opening of the drainage trough 29 after drainage is completed through the cooperation of the side sleeve 301, torsion spring 302, turntable 303 and dust baffle 304, preventing external dust, debris and insects from entering the drainage channel 22 and causing blockage, and ensuring that the drainage system remains unobstructed for a long time.

[0033] The material selection for the interlayer panel 12 is unrestricted; various materials such as glass, metal plates, stone plates, ceramic plates, or composite panels can be selected according to the building's exterior design requirements, adapting to the facade design needs of different styles and positioning. The overall connection structure, through the assembly method of integrated profile molding and plug-in hooking, enables the system to withstand wind pressure loads within the design range, while accommodating interlayer horizontal and vertical displacements generated during normal building use. The continuously arranged sealing strips 21 effectively block air penetration, and the multi-layer waterproof and drainage structure prevents rainwater from seeping into the building interior. All performance aspects meet the usage requirements of the building's external envelope. The UW180 window-wall system constructed using the connection structure of this invention has undergone comprehensive performance testing according to standards such as ASTM E283, ASTM E331, AAMA 501.1, ASTM E330, AAMA 501.4, and AAMA 501.7. Test results show that: air permeability meets the requirements of ASTM E283; static and dynamic pressure water tightness both passed a 15-minute leak-free test; structural performance showed no visible damage under 100% design load (±46.6 psf); and no visible damage or permanent deformation was observed after inter-story horizontal displacement (±3 / 4 inch, 3 cycles) and inter-story vertical displacement (±3 / 4 inch, 3 cycles) tests. This system has passed all Intertek tests, confirming its reliability in terms of air tightness, water tightness, wind pressure resistance, and inter-story displacement adaptability.

[0034] Appendix Figure 7The diagram shows a visible frame connection structure, where the panel is fixed to the outside of the frame by a pressure plate. For visible frame systems or exterior decoration structures such as snap-on covers and decorative strips added to the outside of concealed frames, as long as their internal connection structure still adopts the insertion principle of the upper window sleeve, lower window sleeve, interlayer panel and large panel as described in this invention, regardless of whether the interlayer panel is convex or concave, it belongs to the equivalent replacement solution of this invention and also falls within the protection scope of this invention.
