Description

Technical Field

[0001] This invention relates to the field of building curtain wall engineering technology, and in particular to a modular prefabricated curtain wall structure. Background Technology

[0002] A curtain wall is a building exterior cladding structure assembled from panels and a supporting structural system (such as longitudinal beams, transverse beams, and frames) through modular design. It typically uses materials such as glass, metal panels, and stone as panels, combined with a framework of aluminum alloys or steel to form an integrated wall surface. Its core characteristic is the integration of building enclosure and decorative functions. Through standardized prefabrication and on-site assembly construction methods, it is suitable for the exterior wall construction of large buildings such as high-rise buildings and commercial complexes, combining functionality and industrialization features.

[0003] The function of curtain walls is mainly reflected in two aspects: architectural function and architectural aesthetics. Functionally, as the external envelope of a building, curtain walls provide reliable protection for the interior space, effectively blocking the intrusion of wind, rain, and noise. Simultaneously, through the rational design of door and window positions and opening methods, they meet the needs of indoor ventilation and lighting, enhancing the comfort of living or using the space. Furthermore, modern curtain walls often use energy-saving materials, such as Low-E glass and insulated metal profiles, which can significantly reduce building energy consumption and meet the requirements of green building development. Aesthetically, curtain walls, with their simple and clean lines, transparent and light texture, and rich and diverse color combinations, greatly change the heavy feel of traditional building facades, giving buildings a modern and fashionable feel. Large-area glass curtain walls can allow the building to complement its surrounding environment, creating a unique visual effect; metal or stone curtain walls can showcase the building's stability and grandeur. Curtain walls of different materials and design styles can adapt to the aesthetic needs of various buildings, becoming an important element in shaping the urban architectural image. The combination of function and aesthetics makes curtain walls an indispensable part of modern architecture, ensuring the building's performance while promoting innovation and development in architectural design concepts.

[0004] In existing technologies, traditional modular prefabricated curtain walls mostly use rigid connection nodes (such as welded angle steel and direct bolt fixing), which lack multi-dimensional buffering capabilities and cannot adapt to multi-dimensional deformations such as horizontal displacement, vertical settlement, and angular deflection of the building body. This can easily lead to stress concentration, causing glass panel cracking and node leakage. Furthermore, existing shock-absorbing structures such as single springs or rubber pads can only provide vertical buffering and are unable to dissipate lateral vibration energy. Independent stress between adjacent modules can easily lead to local overload failures. Therefore, a modular prefabricated curtain wall structure is proposed to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a modular prefabricated curtain wall structure that solves the problems of stress concentration, leakage, and low installation efficiency caused by rigid connection nodes lacking multi-dimensional buffering capacity, single shock-absorbing structure, and uneven load between adjacent modules in the existing modular prefabricated curtain wall technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A modular prefabricated curtain wall structure includes longitudinal beams, horizontal beams, and glass panels.

[0009] Preferably, the opposite sides of the plurality of dampers are rotatably connected to the inner wall of the curtain wall mounting cavity, and the opposite sides of the plurality of support springs are fixedly connected to the adjacent sides of the two crossbeams.

[0010] Preferably, the mounting mechanism includes multiple reset springs, and grooves are provided at the four outer corners of the mounting plate. The adjacent sides of the multiple reset springs are fixedly connected to the inner wall of the adjacent side of the multiple grooves. Sliding blocks are fixedly connected to the side of the two reset springs near the L-shaped plate, and a locking block is fixedly connected to the side of the sliding block near the L-shaped plate. Multiple positioning posts are fixedly connected to the upper and lower sides of the mounting plate respectively.

[0011] Preferably, the outer wall of the sliding block is slidably connected to the inner wall of the groove, the outer wall of the locking block is engaged with the inner wall of the L-shaped plate, and the outer walls of the two positioning posts are slidably connected to the inner wall of the L-shaped plate.

[0012] Preferably, the guiding mechanism includes a guide plate, the bottom side of which is fixedly connected to the top side of the lower crossbeam, the top side of which contacts the bottom side of the upper crossbeam, a T-shaped block slidably connected to the inner wall of the guide plate, the front end of which is fixedly connected to the rear end of the mounting plate, an elastic sleeve fixedly connected to the outside of the T-shaped block, the outer side of which contacts the inner wall of the guide plate, and an elastic pad fixedly connected to the front side of the guide plate, the front side of which contacts the rear side of the mounting plate.

[0013] Preferably, the protection mechanism includes four elastic blocks, the front ends of the four elastic blocks are fixedly connected to the four rear corners of the mounting plate, and a square frame pad is fixedly connected to the rear side of the elastic blocks.

[0014] Preferably, the sealing mechanism includes a sealing frame strip, the inner wall of which is fixedly connected to the outer wall of the glass panel, a sealing strip one fixedly connected to the left and right sides of the front end of the longitudinal beam, a sealing strip two fixedly connected to the upper and lower sides of the front end of the cross beam, a vertical frame plate fixedly connected to the front end of the longitudinal beam, and a pressure plate fixedly connected to the front end of the vertical frame plate.

[0015] Preferably, the rear side of the glass panel contacts the front side of the two sealing strips, the rear side of the glass panel contacts the front side of the two sealing strips, the adjacent side of the two sealing frame strips contacts the left and right sides of the upright frame plate, and the rear side of the pressure plate contacts the front side of the two glass panels.

[0016] In summary, the present invention has at least one of the following beneficial technical effects: 1. In this invention, the shock absorption mechanism, through the sliding cooperation between the fixed column and the sleeve, combined with the elastic deformation of the buffer springs one and two and the hydraulic damping of the damper, can absorb the multi-dimensional vibration energy caused by external forces such as earthquakes, and support the spring to balance the load between the beam and the L-shaped plate, reducing local stress concentration. This structure enables the curtain wall to have dynamic stress compensation capability, reduces the impact of vibration on the mounting plate and glass panel, improves the seismic fortification level, and extends the service life.

[0017] 2. In this invention, the installation mechanism uses the rigid guide of the positioning column inserted into the positioning hole of the L-shaped plate to limit the left and right offset of the installation plate and ensure that the card block is accurately aligned with the card slot; the reset spring drives the card block to automatically pop out and engage, replacing the traditional manual alignment and bolt fixing method. This design will shorten the module installation time, significantly improve construction efficiency and reduce manual operation errors.

[0018] 3. In this invention, the guiding mechanism uses the T-shaped groove of the guide plate to rigidly limit the T-shaped block, guiding the installation plate to move linearly along the vertical path to avoid deviation. The double buffer structure of the elastic sleeve and elastic pad can absorb the lateral impact force and forward force during the installation process, preventing the glass panel from breaking due to collision and ensuring the overall flatness and verticality of the curtain wall.

[0019] 4. In this invention, the elastic block of the protective mechanism absorbs vibration energy through rubber deformation during transportation, and the square frame pad evenly distributes the impact force to the four corners of the mounting plate, reducing the damage rate during transportation. After installation, the elastic block can compensate for the flatness error of the wall surface through compression deformation, reducing on-site chiseling procedures and improving installation efficiency. At the same time, it continuously buffers the micro-displacement stress of the wall during the use stage.

[0020] 5. In this invention, the sealing mechanism forms the first waterproof barrier through the elastic compression of the sealing frame strip and sealing strip one and sealing strip two. The upright frame plate presses the sealing frame strip to enhance the lateral sealing performance. The pressure plate mechanically presses the glass panel tightly against the sealing strip. The synergistic effect of multiple structures blocks most of the rainwater penetration path, while improving the panel installation firmness and the airtightness and watertightness of the curtain wall.

[0024] Reference Figure 1 , Figure 4 and Figure 5 This invention provides a modular prefabricated curtain wall structure, including longitudinal beams 1, horizontal beams 2, and glass panels 3. The longitudinal beams 1 and horizontal beams 2 are assembled to form a modular curtain wall installation cavity. The longitudinal beams 1 and horizontal beams 2 are made of aluminum alloy or steel and are assembled by bolts or slots to form a rectangular frame curtain wall installation cavity, which serves as the basic support structure of the curtain wall. The longitudinal beams 1 are arranged vertically and the horizontal beams 2 are arranged horizontally. The two are fixed by corner brackets or prefabricated connectors to form a standardized grid unit. The four corners inside the curtain wall installation cavity are provided with shock-absorbing mechanisms 5. The rear side of the glass panel 3 is fixedly connected to the mounting plate 4. The four corners inside the mounting plate 4 are provided with mounting mechanisms 6. The top of the horizontal beam 2 is provided with a guide mechanism 7. The rear side of the mounting plate 4 is provided with a protection mechanism 8. The exterior of the glass panel 3 is provided with a sealing mechanism 9. The glass panel 3 is the exposed decorative and enclosure component of the curtain wall and is made of safety glass such as tempered glass or laminated glass. It is fixedly connected to the mounting plate 4 by structural adhesive. The mounting plate 4 is a rectangular plate made of aluminum alloy or galvanized steel plate. Specifically, the longitudinal beam 1 and the transverse beam 2 are modularly assembled to form a standardized installation cavity, enabling rapid construction of the curtain wall frame and reducing frame assembly time. The combination of aluminum alloy and steel materials with bolts and slot connections enhances the load-bearing capacity of the installation cavity, meeting the load requirements of high-rise buildings. The modular prefabrication of glass panels 3 and installation plates 4 reduces on-site cutting procedures and improves panel installation accuracy. At the same time, the structural adhesive connection enhances the overall rigidity and improves the wind load resistance of the curtain wall.

[0025] Reference Figure 5 , Figure 6 and Figure 7 The damping mechanism 5 includes two fixed seats 51. The outer walls of the fixed seats 51 are fixedly connected to the inner wall of the curtain wall mounting cavity. A fixed column 52 is rotatably connected to the outside of the fixed seats 51. The fixed seats 51 serve as basic connecting components, fixing the damping mechanism 5 to the inner wall of the curtain wall mounting cavity and providing a fulcrum for the fixed column 52. A buffer spring 53 is sleeved on the outside of the fixed column 52. A compression spring plate 54 is fixedly connected to the side of the fixed column 52 away from the fixed seats 51. A second buffer spring 56 is fixedly connected to the side of the compression spring plate 54 away from the fixed column 52. The sleeve 55 is slidably connected to the wall. The fixed column 52 allows the mounting plate 4 to move in the vertical and horizontal directions through sliding cooperation with the sleeve 55. The outer wall of the compression spring plate 54 is slidably connected to the inner wall of the sleeve 55. The adjacent sides of the buffer spring 1 53 and the buffer spring 2 56 are fixedly connected to the upper and lower sides of the compression spring plate 54, and the distant sides of the buffer spring 1 53 and the buffer spring 2 56 are fixedly connected to the inner walls of the upper and lower sides of the sleeve 55. The buffer spring 1 53 and the buffer spring 2 56 absorb the vibration impact energy by compression or stretching deformation of the compression spring plate 54. A connecting rod 57 is fixedly connected to the side of the sleeve 55 away from the fixed base 51. A rotating base 58 is rotatably connected to the side of the connecting rod 57 away from the sleeve 55. L-shaped plates 59 are fixedly connected to the sides of the two rotating bases 58 near the mounting plate 4. The adjacent sides of the four L-shaped plates 59 contact the four outer corners of the mounting plate 4. The sleeve 55 is connected to the L-shaped plates 59 via the connecting rod 57 and the rotating base 58, allowing the L-shaped plates 59 to swing synchronously with the mounting plate 4 and transmit force. The side of the L-shaped plates 59 away from the mounting plate 4 is fixed. A damper 510 is connected, and the far sides of multiple dampers 510 are rotatably connected to the inner wall of the curtain wall mounting cavity. The piston of the damper 510 reciprocates in the cylinder, and the lateral vibration energy is consumed by hydraulic oil damping. Multiple L-shaped plates 59 are fixedly connected to the side of the crossbeam 2 with support springs 511. The far sides of multiple support springs 511 are fixedly connected to the near sides of two crossbeams 2. The support springs 511 connect the adjacent crossbeams 2 and the L-shaped plates 59 to balance the load between modules and avoid local stress concentration. Specifically, the sliding fit between the fixed column 52 and the sleeve 55, combined with the buffer spring 53 and the buffer spring 56, can absorb the impact energy generated by vertical and horizontal displacement, effectively reducing vibration acceleration. The damper 510 dissipates the energy of lateral vibration, significantly reducing the risk of glass panel 3 cracking due to vibration. The support spring 511 balances the load of adjacent modules, avoids overload of a single module, and improves the overall seismic fortification intensity of the curtain wall.

[0026] Reference Figure 4 , Figure 6 and Figure 8 The mounting mechanism 6 includes multiple return springs 62. Grooves 61 are provided at each of the four outer corners of the mounting plate 4. The adjacent sides of the multiple return springs 62 are fixedly connected to the inner walls of the adjacent sides of the multiple grooves 61. Sliding blocks 63 are fixedly connected to the sides of two return springs 62 near the L-shaped plate 59. The outer walls of the sliding blocks 63 are slidably connected to the inner walls of the grooves 61. The grooves 61 at the four corners of the mounting plate 4 provide movement space for the sliding blocks 63. The return springs 62 are installed inside the grooves 61. A locking block 64 is fixedly connected to the side of the sliding block 63 near the L-shaped plate 59. The outer wall of the locking block 64 is flush with the inner wall of the L-shaped plate 59. The inner walls engage, and the locking block 64 contacts the inner wall of the L-shaped plate 59 through the inclined structure. When pressed, it can retract into the groove 61 and pop out to engage with the L-shaped plate 59, realizing the quick locking of the mounting plate 4 and the shock absorption mechanism 5. Multiple positioning posts 65 are fixedly connected to the upper and lower sides of the mounting plate 4 respectively. The outer walls of two positioning posts 65 are slidably connected to the inner wall of the L-shaped plate 59. The positioning posts 65 are fixed to the upper and lower sides of the mounting plate 4. After being inserted into the corresponding holes of the L-shaped plate 59, the left and right displacement of the mounting plate 4 is restricted by the cooperation between the post wall and the hole wall, ensuring that the locking block 64 is accurately aligned with the slot, improving the installation guidance and stability. Specifically, the positioning post 65 and the hole of the L-shaped plate 59 form a rigid guide, reducing the left and right offset error of the mounting plate 4. The automatic engagement mechanism of the locking block 64 and the return spring 62 shortens the installation time of a single module. The sliding design of the groove 61 and the sliding block 63 is compatible with dimensional tolerances, reducing installation rework caused by processing errors and improving on-site installation efficiency.

[0027] Reference Figure 5 , Figure 6 and Figure 9The guiding mechanism 7 includes a guide plate 71. The bottom side of the guide plate 71 is fixedly connected to the top side of the lower crossbeam 2, and the top side of the guide plate 71 contacts the bottom side of the upper crossbeam 2. A T-shaped block 73 is slidably connected to the inner wall of the guide plate 71. The guide plate 71 is fixed to the top of the crossbeam 2, and its internal T-shaped groove provides a sliding track for the T-shaped block 73 at the rear end of the mounting plate 4. The front end of the T-shaped block 73 is fixedly connected to the rear end of the mounting plate 4. The upper and lower walls of the T-shaped groove restrict the forward and backward displacement of the T-shaped block 73, and the left and right walls guide the vertical movement path. To ensure accurate installation trajectory, the T-block 73 is externally fixedly connected to an elastic sleeve 74. The outer side of the elastic sleeve 74 contacts the inner wall of the guide plate 71. The elastic sleeve 74 on the outer side of the T-block 73 is made of elastic material. When it contacts the inner wall of the guide plate 71, it absorbs the lateral impact force through deformation to reduce installation collisions. An elastic pad 72 is fixedly connected to the front side of the guide plate 71. The front side of the elastic pad 72 contacts the rear side of the mounting plate 4. The elastic pad 72 further buffers the forward impact force during installation to prevent the glass panel 3 from being damaged by impact. Specifically, the T-shaped groove of the guide plate 71 rigidly limits the T-shaped block 73, ensuring the vertical installation accuracy of the mounting plate 4 and improving the overall flatness of the curtain wall; the double buffer of the elastic sleeve 74 and the elastic pad 72 reduces the impact force on the glass panel 3 during installation, avoids edge cracking caused by collision, and improves the integrity rate of the panel.

[0028] Reference Figure 5 and Figure 6 The protective mechanism 8 includes four elastic blocks 81. The front ends of the four elastic blocks 81 are fixedly connected to the four rear corners of the mounting plate 4. The elastic blocks 81 are made of elastic materials such as rubber. When they come into contact with the outside world during transportation, they are compressed and deformed. They store energy through molecular chain stretching, reducing the transmission of vibration to the glass panel 3. A square frame pad 82 is fixedly connected to the rear side of the elastic blocks 81. The square frame pad 82 is a rigid structure and is fixed to the rear side of the elastic blocks 81. It evenly distributes the impact force to the four corners of the mounting plate 4, avoiding local stress concentration that could cause the glass edge to crack. After installation, if the wall surface is uneven, the elastic blocks 81 automatically compensate for the deviation through compression deformation, reducing the on-site chiseling process and improving installation efficiency. At the same time, during the use stage, it continuously buffers the squeezing force generated by the micro-displacement of the wall. Specifically, the rubber material of the elastic block 81 absorbs vibration energy through compression deformation during transportation, reducing the deformation rate of the module during hoisting. The square frame pad 82 disperses the impact force to the four corners of the mounting plate 4, reducing stress concentration at the edge of the glass panel 3. After installation, the elastic block 81 automatically compensates for the flatness error of the wall, reducing the amount of on-site chiseling work and shortening the installation cycle.

[0029] Reference Figure 1 , Figure 2 and Figure 3The sealing mechanism 9 includes a sealing frame strip 93. The inner wall of the sealing frame strip 93 is fixedly connected to the outer wall of the glass panel 3. Sealing strips 91 are fixedly connected to the left and right sides of the front end of the longitudinal beam 1. The rear side of the glass panel 3 contacts the front sides of the two sealing strips 91. Sealing strips 92 are fixedly connected to the upper and lower sides of the front end of the crossbeam 2. The rear side of the glass panel 3 contacts the front sides of the two sealing strips 92. The sealing frame strip 93 is fixed to the edge of the glass panel 3 and contacts the sealing strips 91 and 92 on the longitudinal beam 1 and crossbeam 2 during panel installation. Through elastic compression, it fills the gap between the panel and the profile, forming the first waterproof seal. The front end of the longitudinal beam 1... A frame plate 94 is fixedly connected. The adjacent sides of two sealing strips 93 are in contact with the left and right sides of the frame plate 94. The frame plate 94 is fixed to the front end of the longitudinal beam 1 by screws. The inner side of the frame plate 94 presses the sealing strips 93, forcing the sealing strips 93 to further squeeze the side of the panel, enhancing the lateral sealing performance and blocking the rainwater penetration path. A pressure plate 95 is fixedly connected to the front end of the frame plate 94. The rear side of the pressure plate 95 is in contact with the front side of the two glass panels 3. The pressure plate 95 mechanically presses the glass panels 3 with bolts, so that the panels are tightly fitted to the sealing strips. This improves the installation stability and ensures that the sealing strips reach the designed compression amount, achieving the synergistic effect of multiple sealing and structural fastening. Specifically, the triple elastic compression of the sealing frame strip 93 with sealing strip 91 and sealing strip 92 forms a reliable sealing layer, improving water tightness and air tightness. The mechanical compression of the upright frame plate 94 and the pressure plate 95 enables the sealing strip to reach the designed compression amount, extending the sealing aging cycle, reducing the leakage rate, and at the same time improving the panel's pull-out resistance and enhancing structural safety.

[0030] Working principle: When the mounting plate 4 is subjected to external force such as an earthquake and causes vertical and horizontal displacement, the fixed column 52 rotates slightly around the fixed base 51 and slides in the sleeve 55, which drives the compression spring plate 54 to compress or stretch the buffer spring 1 53 and the buffer spring 2 56. The impact energy is absorbed through the deformation of the springs. At the same time, the piston of the damper 510 reciprocates in the cylinder, and the lateral vibration energy is consumed through hydraulic oil damping. Meanwhile, the support spring 511 is compressed or stretched between the crossbeams 2 to balance the load between modules and reduce the impact of vibration on the mounting plate 4 and the glass panel 3. When installing glass panel 3, mounting plate 4 first moves vertically, and positioning post 65 on the bottom side aligns with positioning hole of L-shaped plate 59 and is inserted, guiding mounting plate 4 into preset position in curtain wall mounting cavity and limiting its left and right offset. When mounting plate 4 continues to move down until the locking block 64 contacts the inner wall of L-shaped plate 59, the inclined surface of locking block 64 is squeezed and pushes sliding block 63 to slide into groove 61, compressing return spring 62 until locking block 64 reaches the slot position on inner wall of L-shaped plate 59. Return spring 62 releases elasticity and pushes sliding block 63 out, so that locking block 64 is embedded in slot, completing the mechanical locking of mounting plate 4 and shock absorption mechanism 5. During installation, support spring 511 ensures accurate installation position of shock absorption mechanism 5 and L-shaped plate 59. The T-shaped block 73 at the rear end of the mounting plate 4 is inserted into the T-shaped groove of the guide plate 71. The upper and lower walls of the T-shaped groove restrict the forward and backward displacement of the T-shaped block 73, while the left and right walls guide it to slide in a straight line in the vertical direction, ensuring that the mounting plate 4 moves along the preset path. When the mounting plate 4 is laterally offset due to external force, the elastic sleeve 74 on the outer side of the T-shaped block 73 contacts the inner wall of the guide plate 71 and is compressed and deformed. The lateral impact force is absorbed through elastic deformation. At the same time, the elastic pad 72 contacts the rear side of the mounting plate 4, slowing down its forward impact speed. As the mounting plate 4 continues to move, the T-shaped block 73 slides in the guide groove until it reaches the predetermined position, completing the deviation-free positioning. During transportation, when the elastic block 81 on the back of the glass panel 3 comes into contact with the transport bracket or wall, the elastic block 81 is compressed and deformed, and the internal rubber molecular chains stretch and store energy. At the same time, the square frame pad 82 distributes the impact force to the four corners of the mounting plate 4 due to rigid support, avoiding local stress concentration. After the external force disappears, the elastic block 81 returns to its original shape through its own elasticity and releases the stored energy. After installation, when the elastic block 81 comes into contact with the wall, if the flatness error of the wall surface is large, the elastic block 81 automatically compensates for the deviation through compression deformation, reducing the on-site "chising and repair" process and improving installation efficiency. When installing the glass panel 3, the sealing frame strip 93 on the edge of the panel first contacts the sealing strip 91 and sealing strip 92 on the longitudinal beam 1 and the transverse beam 2. As the panel is pushed forward, the sealing strip is squeezed and undergoes elastic deformation, filling the gap between the panel and the profile to form the first seal. Subsequently, the vertical frame plate 94 is fixed to the front end of the longitudinal beam 1 with screws, and its inner side presses the sealing frame strip 93, so that the sealing frame strip 93 further squeezes the side of the panel to enhance the lateral sealing performance. Finally, the pressure plate 95 is fixed to the front end of the vertical frame plate 94 with bolts, and presses the glass panel 3 forward to make the panel fit tightly against the sealing strip and compress the sealing strip to the designed compression amount. The combined effect of multiple mechanical compression and elastic deformation blocks the path of rainwater and air penetration, and at the same time, the installation stability of the panel is improved by fixing it with the pressure plate 95.
