Description

Technical Field

[0001] This invention belongs to the field of building curtain wall structure technology, specifically relating to a rapid installation structure and construction method for complex building curtain walls. Background Technology

[0002] Building curtain walls are a mainstream exterior cladding system for modern buildings. Suspended on the exterior of the building structure, they do not bear the main load and serve multiple functions including enclosure, decoration, and insulation. They are widely used in high-rise and public buildings. With the development of industrialized construction, the industry has raised higher standards for the assembly efficiency, installation accuracy, and joint sealing durability of curtain walls. Existing curtain walls are mainly divided into two categories: component-type curtain walls and prefabricated unitized curtain walls. Traditional component-type curtain walls are constructed on-site, requiring multiple steps such as embedding plates, keels, panels, and sealing. This method is highly dependent on manual labor, involves cumbersome procedures, and is susceptible to environmental and manual operation variations during high-altitude work. Alignment, leveling, and rectification are labor-intensive, resulting in long construction cycles and poor assembly accuracy, failing to meet the demands of rapid and standardized construction. While existing unitized curtain walls achieve factory prefabrication and on-site hoisting, they are mostly rigid interlocking structures with low assembly error tolerance. They are difficult to adapt to on-site civil engineering deviations, and rework and rectification are cumbersome, limiting the improvement in assembly efficiency.

[0003] Meanwhile, the existing sealing structure for the joints between adjacent curtain wall panels has significant defects. It generally employs a single sealing method of on-site foam padding and manual application of sealant, lacking a suitable prefabricated sealing structure. Manual application of sealant is prone to quality problems such as uneven sealant layer, sealant breaks, and air bubbles, resulting in poor seal continuity. Furthermore, the single sealant layer is easily aged and cracked under long-term exposure to wind pressure, rainwater, ultraviolet radiation, and the stretching caused by panel deformation, leading to water seepage and air leakage at the joints. Moreover, the existing fixed structure and sealing structure are independent of each other; slight displacement can easily occur after panel assembly, further compromising the seal integrity, leading to curtain wall leakage, dust accumulation, reduced thermal and sound insulation performance, and even keel corrosion, significantly increasing subsequent operation and maintenance costs.

[0004] In summary, existing curtain wall structures struggle to balance efficient, standardized assembly with long-term sealing and protection, exhibiting numerous shortcomings such as low construction efficiency, poor assembly precision, easy leakage at joints, and weak durability. Therefore, this application proposes a novel building curtain wall structure to address the deficiencies of existing technologies. Summary of the Invention

[0005] In view of this, the purpose of this invention is to provide a rapid installation structure and construction method for complex building curtain walls, in order to solve the problem that current curtain wall structures cannot simultaneously achieve efficient and standardized assembly and long-term sealing and protection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A rapid installation structure for a complex building curtain wall includes a keel support system fixed to the exterior wall of the building and multiple connecting shells and curtain walls installed on its surface. The connecting shells are regularly arranged, and any four adjacent connecting shells are detachably connected to one curtain wall. Each curtain wall has a vertically arranged connecting frame on its exterior wall-facing side. Each connecting frame is arranged around the outline of the curtain wall and spaced a distance from its edge. Each vertical corner of the connecting frame has a connecting hole corresponding to an adjacent connecting shell. Each connecting shell has multiple vertically elastically sliding locking blocks on its surface, and the number and position of each locking block correspond to the adjacent connecting holes. One end of each of the aforementioned blocks protrudes from the surface of the connecting housing, and the direction of movement is perpendicular to the direction of movement of the corresponding connecting hole. The free end of each of the aforementioned blocks is beveled on the side surface that contacts the connecting frame. Any two adjacent connecting housings are detachably connected to a shielding block, and the surface of the shielding block simultaneously abuts against the surfaces of two adjacent curtain walls. Each shielding block is located between the curtain wall and the building exterior wall, and one side surface of the shielding block is provided with a first sealing strip for shielding the gap between adjacent curtain walls. One side surface of each of the aforementioned connecting housings is provided with multiple second sealing strips, and the second sealing strips are regularly distributed and abut against the corresponding curtain wall surfaces.

[0007] Furthermore, each of the aforementioned shielding blocks has two sliders slidably connected inside, and the two sliders are symmetrically arranged about the axis of the shielding block's length direction. The two sliders are arranged along the length direction of the shielding block and move in the vertical plane, and their opposite ends are both inserted through the surface of the shielding block. Each of the aforementioned connecting frames has a sealing groove that mates with the sliders. One side surface of each of the aforementioned first sealing strips has a transmission block that is elastically slidably inserted through the shielding block, and the free end of each transmission block is poweredly connected to a transmission component that drives the sliders to move synchronously. The transmission component is located inside the shielding block.

[0008] Furthermore, each slider is connected to an abutment block on its end face, and each abutment block is elastically slidably inserted through the slider. The free end of the abutment block abuts against the surface of the corresponding sealing groove. Each slider has through holes on both sides along its length, and each through hole is covered with a flexible sealing membrane. One end face of each abutment block and the inside of the slider together form a sealed chamber, and each through hole is connected to the sealed chamber.

[0009] Furthermore, the transmission component includes a transmission rod rotatably disposed within the blocking block, a transmission gear coaxially sleeved and fixed to the outer surface of the transmission rod, and a rack fixed to each transmission block. The transmission rod is arranged along the movement direction of each slider, and both ends of the transmission rod are rotatably connected to the surface of the blocking block. The transmission gear is disposed at the center of the transmission rod along its length, and each transmission gear meshes with a corresponding rack. Multiple transmission components and transmission blocks are provided and arranged in an array along the length direction of the blocking block. Multiple connecting ears coaxially sleeved on the outer surface of the transmission rod are fixed to one side surface of each slider, and the connecting ears are threadedly connected to the transmission rod.

[0010] Furthermore, both ends of each of the shielding blocks along its length are detachably connected to the connecting housing via a tenon and mortise structure.

[0011] Furthermore, the connecting housing, shielding block, slider, and abutment block are all made of stainless steel.

[0012] A rapid installation method for complex building curtain walls, applied to a rapid installation structure for complex building curtain walls, includes the following implementation steps; Step 1: Erect the keel support system: Fix multiple horizontal bars to the exterior wall of the building, and then fix the vertical poles to the horizontal bars. The horizontal bars and vertical poles are crisscrossed to form several rectangular cavity areas. Step 2: Install and position the connecting housings: Install and fix each connecting housing at the intersection of the horizontal and vertical poles. After installation, level and correct all connecting housings to ensure installation accuracy. Once any four adjacent connecting housings are installed, the installation can be carried out simultaneously with the curtain wall hoisting operation. Step 3, Pre-fabrication of the curtain wall: Select the appropriate fixing method according to the material of the curtain wall panel, fix the connecting frame with the sealing groove to the inside of the curtain wall, and open the connection holes of the matching clips at the four corners of the connecting frame. Step 4, Curtain wall alignment, hoisting, and locking: Hoist the curtain wall to the corresponding rectangular cavity and push it horizontally towards the building's exterior wall. The beveled edges of the connecting frame press against the beveled elastic blocks of the connecting housing, causing the blocks to compress the springs and retract. Continue pushing until the connecting holes are aligned with the blocks. The blocks then pop out under the spring force and lock into the connecting holes, completing the curtain wall locking process. Step 5, Triple Sealing Simultaneous Forming: The first sealing strip on the curtain wall's adhesive shielding block and the second sealing strip on the connecting shell form a basic flexible seal; the first sealing strip, under pressure, drives the transmission block, which, through a rack, transmission gear, and transmission rod thread transmission, drives the sliders on both sides to extend and embed into the sealing groove of the connecting frame, forming a mechanical fitting seal; the inner wall of the sealing groove squeezes the abutment block to retract and compress the gas in the sealing chamber, and the gas pushes the sealing membrane of the open hole to expand and adhere to the groove wall, forming a gas pressure expansion seal. The triple sealing is completed simultaneously, and the construction is finished.

[0013] The beneficial effects of this invention are as follows: This invention employs a standardized prefabricated structure with horizontal and vertical keels and a cross-shaped connecting shell, enabling simultaneous construction of the connecting shell positioning and curtain wall installation. Combined with angled guides and elastic locking structures, it achieves rapid alignment and locking. The assembly process is simple and highly versatile, achieving standardized and efficient curtain wall construction and significantly improving assembly accuracy and construction efficiency. Simultaneously, this structure specifically optimizes the sealing and protection system, abandoning the limitations of traditional single flexible seals. It uses sealing strips to construct a basic flexible seal, combined with mechanical interlocking seals via gear and rack linkage sliders and air pressure expansion seals in the sealing chamber, forming a triple-progressive sealing and protection structure. This structure can adapt to assembly gap deviations and comprehensively seal curtain wall splicing gaps. Furthermore, the core components use corrosion-resistant stainless steel with a mortise and tenon detachable structure, effectively resisting outdoor rainwater and ultraviolet radiation, possessing excellent aging compensation performance, and avoiding sealing failure and leakage problems after long-term use. It perfectly balances the dual needs of standardized rapid curtain wall assembly and long-term stable sealing and protection, making it suitable for long-term use in complex outdoor conditions.

[0016] like Figures 1-7 As shown, A rapid installation structure for a complex building curtain wall includes a keel support system 2 fixed to the exterior wall 1 of the building, and multiple connecting shells 3 and a curtain wall 4 installed on its surface. The keel support system 2 includes multiple horizontally arranged crossbars 201 and multiple vertically arranged uprights 202. Each crossbar 201 is fixed to the surface of the exterior wall 1 by expansion bolts, and each upright 202 is fixed to the surface of the crossbar 201 by bolts and nuts. The crossbars 201 and uprights 202 are arranged in a crisscross pattern in the vertical plane and together form multiple rectangular cavity areas for placing the curtain wall 4. Each of the connecting housings 3 is fixedly installed at the intersection of the horizontal bar 201 and the vertical bar 202 by bolts and nuts, and arranged in a regular pattern. Each connecting housing 3 is shaped like a cross in the vertical plane, and any four adjacent connecting housings 3 are detachably connected to one of the curtain walls 4 by their right-angled sides. Each curtain wall 4 has a connecting frame 5 protruding vertically on the side of its surface facing the building exterior wall 1. Each connecting frame 5 is set around the outline of the curtain wall 4 and spaced a distance from its edge. Each of the four vertical corners of the connecting frame 5 has a connecting hole 6 corresponding to the adjacent connecting housing 3 (two connecting holes 6 are shown at each right-angled side in the figure). Each connecting housing 3 has multiple locking blocks 7 that slide vertically and elastically on its surface. The number and position of each locking block 7 correspond to the adjacent connecting holes 6. One end of each locking block 7 protrudes from the surface of the connecting housing 3, and the direction of movement is the same as that of the corresponding connecting frame 5 and connecting hole 6. The directions of movement are perpendicular to each other. The free end of each of the card blocks 7 is beveled on the side of the edge that contacts the connecting frame 5. The side of the connecting frame 5 that contacts the card block 7 is also beveled. Any two adjacent connecting shells 3 are detachably connected to a shielding block 8. The surface of the shielding block 8 abuts against the surfaces of two adjacent curtain walls 4. Each shielding block 8 is located between the curtain wall 4 and the building exterior wall 1. One side of the shielding block 8 is provided with a first sealing strip 9 for shielding the gap between adjacent curtain walls 4. The first sealing strip 9 abuts against the surfaces of two adjacent curtain walls 4. One side of each connecting shell 3 is provided with four second sealing strips 10. The positions of each second sealing strip 10 correspond one-to-one with the positions of the four adjacent curtain walls 4 and are regularly distributed. Each second sealing strip 10 abuts against the corresponding surface of the curtain wall 4. The first sealing strip 9 and the second sealing strip 10 are both made of flexible rubber material.

[0017] As shown in the diagram, before installing the curtain wall 4, the keel support system 2 is first fixedly installed on the surface of the building's exterior wall 1, ensuring that each rectangular area formed by the horizontal bars 201 and vertical bars 202 corresponds to one curtain wall 4. After the keel support system 2 is installed, the fixed connecting shell 3 is installed at the intersection of the horizontal bars 201 and vertical bars 202. The connecting shell 3 is fixedly connected to the vertical bars 202 with bolts and nuts. After the connecting shell 3 is installed, the construction personnel correct its positioning to ensure its installation accuracy. When any four adjacent connecting shells 3 are installed and positioned, the curtain wall 4 can be hoisted and installed. Therefore, the installation of the connecting shell 3 and the curtain wall 4 can be carried out simultaneously, greatly shortening the construction efficiency. Before installing the curtain wall 4, the connecting frame 5 is first fixed to one side surface of the curtain wall 4. The appropriate fixing method for the connecting frame 5 is selected based on the material of the curtain wall 4 (e.g., metal, ceramic, glass, etc.), which is common knowledge to those skilled in the art and will not be elaborated upon here. During installation, the curtain wall 4 is hoisted to the cavity of the corresponding keel support system 2, and then horizontally moved into the cavity. During this movement, ensure that the four right-angled sides of the connecting frame 5 correspond one-to-one with the four adjacent connecting shells 3. One side surface of the connecting frame 5 first contacts the corresponding locking block 7, and the guide angle sides of the connecting frame 5 and each corresponding locking block 7 are aligned. The two parts abut against each other and push the locking block 7 into the connecting housing 3. The spring between the locking block 7 and the connecting housing 3 is compressed (the spring is not shown in the figure), so that the connecting frame 5 and the curtain wall 4 can continue to move horizontally towards the building exterior wall 1 until each connecting hole 6 corresponds to the position of the corresponding locking block 7. At this time, each locking block 7 passes through the connecting housing 3 under the action of the spring and engages with the connecting hole 6. Since the shape of the locking block 7 passing through the connecting housing 3 is the same as the shape of the connecting hole 6, the fixing effect between the connecting housing 3 and the connecting frame 5 is achieved, which indirectly achieves the effect of fixing the curtain wall 4 to the keel support system 2. The operation is simple and reliable. When the curtain wall 4 is fixed to each of the four adjacent connecting shells 3 under the action of the connecting frame 5, one side surface of the curtain wall 4 will simultaneously abut against the first sealing strip 9 and the second sealing strip 10. Since the first sealing strip 9 and the second sealing strip 10 are both made of flexible rubber, the curtain wall 4 abuts against the first sealing strip 9 and causes it to deform flexibly, effectively sealing the gap between the curtain wall 4 and the shielding block 8. Similarly, each of the second sealing strips 10 abuts against the surface of the curtain wall 4, sealing the gap between the curtain wall 4 and the connecting shell 3. The combination of the two can effectively ensure the waterproof and windproof capabilities of the curtain wall 4, effectively avoiding leakage after long-term use. In addition, any two adjacent curtain wall pieces 4 cooperate with each other and abut against the first sealing strip 9, which can enhance its sealing effect. At the same time, each of the first sealing strips 9 and the second sealing strip 10 can also provide a certain buffering effect for the installation of the curtain wall 4, effectively reducing the vibration generated when the curtain wall 4 abuts against each connecting shell 3 and shielding block 8, and improving the efficiency of installation.

[0018] In this embodiment, each of the shielding blocks 8 has two sliders 11 slidably connected inside, and the two sliders 11 are symmetrically arranged about the axis of the shielding block 8 along its length. The two sliders 11 are arranged along the length of the shielding block 8 and move in the vertical plane. The end faces that are far apart from each other slide through the surface of the shielding block 8. Each of the connecting frames 5 has a sealing groove 12 that cooperates with the slider 11. One side surface of each of the first sealing strips 9 is vertically fixed with a transmission block 13 that is elastically slidably inserted through the shielding block 8. The free end of the transmission block 13 is poweredly connected to a transmission member 14 that drives each slider 11 to move synchronously. The transmission member 14 is disposed inside the shielding block 8. When the connecting hole 6 on the connecting frame 5 is engaged and fixed with the locking block 7, one end of each slider 11 passes through the surface of the shielding block 8 and is located in the sealing groove 12. At the same time, one end of the slider 11 also abuts against the inner wall of the sealing groove 12.

[0019] As shown in the figure, when the connecting frame 5 moves towards the building exterior wall 1 and engages with the connecting housing 3, the surface of the curtain wall 4 facing the building exterior wall 1 abuts against the first sealing strip 9. The first sealing strip 9 then synchronously drives the transmission block 13 to move. The transmission block 13, through the transmission component 14, drives the corresponding two sliders 11 to move synchronously, causing the two sliders 11 to move away from each other. The two ends of the two sliders 11 extend out from the sides of the blocking block 8 and slide into the sealing groove 12. When each connecting hole 6 on the connecting frame 5 engages with the corresponding locking block 7, the sliders 11 in each blocking block 8 also synchronously slide into the sealing groove 12. Furthermore, one end of each slider 11 extending out from the blocking block 8 abuts against the inner wall of the sealing groove 12. The interaction between the slider 11 and the sealing groove 12 further enhances the sealing effect of the gaps between the curtain wall 4 and the shielding block 8. One end of the slider 11 abuts against the sealing groove 12 to form a mechanical fitting. On the basis of the original flexible first sealing strip 9, a mechanical fitting and sealing structure is added to specifically enhance the sealing effect of the splicing gap between the curtain wall 4 and the shielding block 8, effectively preventing heat exchange between the external airflow and the space between the building exterior wall 1 and the curtain wall 4. This linkage sealing structure can adapt to the assembly alignment deviation of the curtain wall 4, always ensuring that the slider 11 and the sealing groove 12 fit tightly, effectively filling the minor assembly gaps, eliminating problems such as air leakage, water seepage, and dust accumulation in the gaps, and making up for the defects of single flexible seals that are prone to poor fitting and aging and loosening. Meanwhile, the overall linkage action is stable and reliable, the structure is concealed and not easily damaged, and it can maintain a high-strength sealing state for a long time, which greatly improves the sealing stability and long-term stability of the curtain wall 4 splicing position, and comprehensively upgrades the overall waterproof, windproof and dustproof airtight protection performance of the curtain wall 4, making it suitable for the harsh working conditions of long-term outdoor use of complex building curtain wall 4.

[0020] In this embodiment, each slider 11 is connected to an abutment block 15 through the end face of the blocking block 8. Each abutment block 15 is elastically slidably inserted through the slider 11, and the free end of the abutment block 15 abuts against the surface of the corresponding sealing groove 12. Each slider 11 has through holes on both sides along its length direction, and each through hole is covered with a flexible sealing film 16. One end face of each abutment block 15 and the interior of the slider 11 together form a sealed chamber, and each through hole is connected to the sealed chamber.

[0021] As shown in the figure, when the connecting frame 5 moves towards the building's exterior wall 1 and engages with the locking block 7, the surface of the curtain wall 4 first abuts against the first sealing strip 9. Through the transmission component 14, the sliders 11 and abutment blocks 15 extend out of the blocking block 8. One end of each abutment block 15 first abuts against the surface of the connecting frame 5. Subsequently, after the connecting hole 6 and the locking block 7 engage, each abutment block 15 is located within the sealing groove 12 and abuts against its surface. At this time, one end of each abutment block 15 slides into the slider 11 under the abutment action of the inner wall of the sealing groove 12. In part, since the abutment block 15 and the slider 11 together form a sealed chamber, when the abutment block 15 slides into the sealing groove 12, the gas in the sealed chamber will pass through the through hole and cause the sealing membrane 16 to expand. The expanded sealing membrane 16 will diffuse into the sealing groove 12 and abut against its inner wall, further strengthening the sealing effect between the slider 11 and the sealing groove 12. This effectively prevents external water and gas from entering the sealed area between the curtain wall 4 and the building exterior wall 1 due to the aging of the first sealing strip 9 and the second sealing strip 10 after long-term use. The sealing structure is further optimized by adding an elastic abutment block 15, a sealing chamber, and a through hole with a sealing membrane 16, forming a pressure-adaptive expansion sealing mechanism. When the curtain wall 4 is assembled, the abutment block 15 is squeezed, which compresses the gas in the chamber and pushes the sealing membrane 16 to expand and adhere to the inner wall of the sealing groove 12, sealing the tiny gaps in the components in all directions. This creates a triple sealing system of flexible sealing, mechanical fitting, and pressure expansion. Its core advantage lies in its good aging compensation ability, which continuously maintains the gap sealing effect, effectively preventing water seepage, air leakage, and dust accumulation problems in the later stage, and greatly improving the durability and outdoor working conditions of the curtain wall 4 sealing system.

[0022] In this embodiment, the transmission component 14 includes a transmission rod 1401 rotatably disposed within the blocking block 8, a transmission gear 1402 coaxially sleeved and fixed to the outer surface of the transmission rod 1401, and a rack 1403 fixed to each transmission block 13. The transmission rod 1401 is disposed along the movement direction of each slider 11, and both ends of the transmission rod 1401 are rotatably connected to the surface of the blocking block 8. The transmission gear 1402 is disposed at the center of the length direction of the transmission rod 1401, and each transmission gear 1402 meshes with a corresponding rack 1403. Multiple transmission components 14 and transmission blocks 13 are provided and arranged in an array along the length direction of the blocking block 8. Multiple connecting ears 1404 coaxially sleeved on the outer surface of the transmission rod 1401 are fixed to one side surface of each slider 11, and the connecting ears 1404 are threadedly connected to the transmission rod 1401. The springs disposed between each transmission block 13 and the blocking block 8 are not shown in the figure.

[0023] As shown in the figure, when the connecting frame 5 and each connecting housing 3 are installed and fitted, one side surface of the curtain wall 4 will first abut against the first sealing strip 9 and simultaneously drive each transmission block 13 to move. Each transmission block 13 will drive the transmission gear 1402 to rotate through the rack 1403. The transmission gear 1402 will then drive the connecting ear 1404 and the two sliders 11 to move away from each other through the thread, so that one end of the slider 11 passes through the shielding block 8 and enters the sealing groove 12. Through the cooperation of multiple transmission blocks 13 and transmission components 14, each slider 11 can be stably slid into the sealing groove 12, ensuring that the sealing structure is evenly fitted and stressed, further consolidating the overall multi-seal effect, and improving the operational stability and service life of the curtain wall 4 sealing system.

[0024] Each of the first sealing strips 9 consists of two mirror-image and independent sealing strips a and b. Each sealing strip a and sealing strip b corresponds to a transmission component 14, a slider 11, and an abutment block 15 (which can be combined). Figure 6 and Figure 7 As shown, when one of the curtain wall 4 is engaged with the four adjacent connecting housings 3, the surface of the curtain wall 4 will simultaneously abut against the corresponding four sealing strips a. When each sealing strip a is abutted by the curtain wall 4 and moves toward the blocking block 8, the sealing strip a will synchronously drive the slider 11 and the end of the abutting block 15 to extend out of the blocking block 8 and slide into the sealing groove 12 through the transmission component 14, thereby achieving a sealing effect between the curtain wall 4 and the blocking block 8. Similarly, when it is necessary to install an adjacent curtain wall 4, this curtain wall 4 will abut against the corresponding sealing strip b, thereby achieving a sealing effect between the curtain wall 4 and each blocking block 8. By adopting the cooperation of each sealing strip a and sealing strip b, the situation where some sliders 11 interfere with the installation of the curtain wall 4 during the installation process can be solved, effectively improving the construction efficiency.

[0025] In this embodiment, both ends of each of the shielding blocks 8 along the length direction are detachably connected to the connecting housing 3 through a tenon and mortise structure, which makes the structure simple and reliable.

[0026] In this embodiment, the connecting housing 3, the shielding block 8, the slider 11, and the abutment block 15 are all made of stainless steel, such as stainless steel 316L; the first sealing strip 9, the second sealing strip 10, and the sealing membrane 16 are all made of flexible sealing rubber material that is resistant to rain corrosion, such as EPDM rubber.

[0027] A rapid installation method for complex building curtain walls, applied to a rapid installation structure for complex building curtain walls, includes the following implementation steps; Step 1, Erecting the keel support system 2: Use expansion bolts to fasten multiple horizontal bars 201 to the surface of the building exterior wall 1, and then use matching bolts and nuts to connect multiple vertical bars 202 to the outside of the horizontal bars 201 in sequence; so that the horizontal bars 201 and vertical bars 202 are arranged in a crisscross pattern in the vertical plane, forming multiple rectangular cavity areas for placing the curtain wall 4, and uniformly correcting the overall flatness of the keel; Step 2: Install and position the connecting housing 3: Use bolts and nuts to fix the cross-shaped connecting housing 3 at the intersections of the horizontal bar 201 and the vertical bar 202 and arrange them neatly; after all the connecting housing 3 are assembled, carry out the correction and positioning operation to calibrate the position of each connecting housing 3 to ensure the overall installation accuracy; when the four adjacent connecting housing 3 are positioned, the curtain wall 4 hoisting and installation process can be carried out simultaneously, and the cross construction shortens the total construction period; the obstruction block 8 can be detachably assembled between two adjacent sets of connecting housing 3 through the tenon and mortise structure. The obstruction block 8 is pre-installed with a transmission component 14 consisting of a transmission rod 1401, a transmission gear 1402, and a rack 1403, a symmetrical slider 11, and an elastic abutment block 15. The obstruction block 8 is equipped with a first sealing strip 9 made of EPDM rubber on the outside. The surface of the connecting housing 3 is pre-installed with a second sealing strip 10 corresponding to the curtain wall 4. The connecting housing 3, obstruction block 8, slider 11, and abutment block 15 are all made of 316L stainless steel. Step 3, Pre-processing of Curtain Wall 4: Select an appropriate fixing process based on the material of Curtain Wall 4 (metal, ceramic glass, etc.), and vertically fix the connecting frame 5, which surrounds the outline of Curtain Wall 4 and leaves a gap with the edge of Curtain Wall 4, on the side of Curtain Wall 4 facing the outer wall; make connecting holes 6 at the four vertical corners of the connecting frame 5 that correspond one-to-one with the locking blocks 7 of the connecting housing 3, and at the same time make sealing grooves 12 on the side wall of the connecting frame 5 that match the slider 11, thus completing the pre-processing of Curtain Wall 4; Step 4, Curtain Wall 4 Alignment, Lifting, and Fixing: Use lifting equipment to lift the finished curtain wall 4 to the rectangular cavity position corresponding to the keel support system 2, and push the curtain wall 4 horizontally towards the building exterior wall 1; during the pushing process, the beveled edge of the connecting frame 5 and the beveled edge of the locking block 7 press against each other, pushing the locking block 7 to compress the internal spring and retract into the connecting housing 3; continue to move the curtain wall 4 until the connecting hole 6 of the connecting frame 5 and the locking block 7 are precisely aligned, the locking block 7 pops out under the spring return force and locks into the matching connecting hole 6, relying on the fit between the locking block 7 and the connecting hole 6 to lock the connecting frame 5 and the connecting housing 3, completing the rapid fixing of the curtain wall 4; Step 5, Triple Sealing and Synchronous Forming: After the curtain wall 4 is fixed, it simultaneously presses against the first sealing strip 9 of the shielding block 8 and the second sealing strip 10 of the connecting shell 3. The flexible rubber deformation seals the gaps between the curtain wall 4 and the connecting shell 3, forming the first layer of flexible seal. The curtain wall 4, by squeezing the first sealing strip 9, simultaneously pushes the transmission block 13 to move. The rack 1403 of the transmission block 13 meshes with the transmission gear 1402, driving the transmission rod 1401 to rotate. The transmission rod 1401, through threaded engagement, drives the sliders 11 on both sides to extend outwards synchronously. The end of the 11 is embedded in the sealing groove 12 of the connecting frame 5 and abuts against the groove wall to form a second layer of mechanical fitting seal; the inner wall of the sealing groove 12 squeezes the elastic abutment block 15 at the end of the slider 11 to retract into the slider 11, compressing the air in the sealing chamber between the abutment block 15 and the slider 11, and the gas in the chamber expands outward through the through hole to push open the flexible sealing membrane 16. The sealing membrane 16 tightly fits the inner wall of the sealing groove 12 to fill the tiny gaps, forming a third layer of air pressure expansion seal; the triple sealing structure is formed synchronously with the curtain wall 4 locking, improving the overall waterproof, windproof and dustproof performance; When any four adjacent connecting shells 3 are installed on the keel support system 2, one curtain wall 4 can be installed. Therefore, as long as the installation speed of the connecting shells 3 is greater than the installation speed of the curtain wall 4, the connecting shells 3 and the curtain wall 4 can be installed synchronously, which greatly improves construction efficiency and reduces the total construction time. In addition, when adjacent curtain walls 4 are installed, they can cooperate with independent sealing strips a and b to achieve non-interference and ensure construction quality until the entire curtain wall 4 is installed.
