Abstract
Description
Technical Field
[0001] This invention relates to a prefabricated unitized curtain wall system. Background Technology
[0002] Building curtain walls are decorative and enclosing structures for the exterior walls of buildings, widely used in various high-rise and public buildings. Existing curtain wall systems are mostly constructed using on-site casting or piecemeal assembly methods, which suffer from low construction efficiency, poor installation accuracy, and insufficient stability of the curtain wall panels.
[0003] In the traditional curtain wall installation process, the position of the curtain wall panels needs to be adjusted manually and repeatedly to ensure uniform splicing gaps. This not only consumes a lot of manpower and resources, but also easily leads to loosening and displacement of the curtain wall panels after installation due to human error, affecting the overall sealing and structural safety of the curtain wall.
[0004] Therefore, there is an urgent need for a prefabricated unitized curtain wall system that is easy to install, securely fixed, highly accurate, easy to maintain, and avoids the risks of thermal expansion and contraction, in order to address the shortcomings of existing technologies. Summary of the Invention
[0005] The technical problem to be solved by the present invention is to provide a prefabricated unitized curtain wall system that is easy to install, firmly fixed, highly accurate, easy to maintain, and avoids the hidden dangers of thermal expansion and contraction.
[0006] To solve the above problems, the present invention adopts the following technical solution: A prefabricated unitized curtain wall system, comprising, Fasteners, which are installed in a rectangular array on the exterior wall of the building; A positioning element is fixedly installed at the end of the fixing element; The combined curtain wall panel is installed and positioned by the positioning member, and the back of the combined curtain wall panel is limited by the fixing member; Decorative clips are detachably installed between two adjacent composite curtain wall panels.
[0007] Preferably, the fastener includes a threaded portion and an end portion, the threaded portion being used to connect with an expansion sleeve, and the end portion having a threaded hole at its axial center, the end portion being used to support the rear end face of the combined curtain wall panel.
[0008] Preferably, a stop washer is provided between the end and the combined curtain wall panel.
[0009] Preferably, the positioning component includes a clamping plate and a positioning plate, which are integrally formed. The positioning plate is cross-shaped, and a stepped hole corresponding to the threaded hole is provided in the middle of the positioning plate. A long screw is screwed into the stepped hole, and the long screw passes through the stepped hole and is screwed into the threaded hole to fix the clamping plate. The clamping plate is engaged in the combined curtain wall panel, and the combined curtain wall panel is positioned by the positioning plate.
[0010] Preferably, the combined curtain wall panel includes an inner frame, an outer frame, a curtain wall panel, and a protective frame. Rectangular grooves are correspondingly provided on the opposite surfaces of the inner frame and the outer frame. The protective frame, after elastic deformation, covers the edge of the curtain wall panel. The protective frame is installed between the inner frame and the outer frame and is embedded in the rectangular groove. A clamping screw is screwed into the outer end face of the outer frame and screwed into the inner frame to clamp the protective frame. When the protective frame is clamped, a slot is formed between the inner frame and the outer frame. The clamping plate is engaged in the slot. The positioning plate is located at the top corner of the outer frame and limits the adjacent installed outer frame. The inner frame is fixed by the clamping plate and the end clamp.
[0011] Preferably, the rear end of the decorative strip is provided with a T-shaped elastic block. After the elastic block deforms elastically, it is inserted into the gap between adjacent outer frames. After being inserted, the elastic block elastically recovers between adjacent slots, so that the decorative strip is fixed.
[0012] Preferably, the curtain wall panel is an insulation board or a tempered glass panel.
[0013] Preferably, the outer side of the protective frame is provided with a raised strip, which is interference-fitted into the slot.
[0014] The beneficial effects of this invention are: 1. Convenient and efficient installation: The prefabricated installation method is adopted layer by layer, eliminating the need for complicated on-site construction procedures. The fasteners, positioning components and combined curtain wall panels are precisely assembled and matched. The positioning plate adopts a cross-shaped structure, which can simultaneously position four adjacent curtain wall panels, eliminating the step of manual assembly and jointing, greatly improving installation efficiency and accuracy, and reducing labor costs. 2. Secure and stable: The combined curtain wall panels are engaged with the positioning plate and the slot, and the back is limited by the end of the fastener. The stop shim fills the installation gap. The multiple fixing structure ensures that the combined curtain wall panels will not loosen after installation. It can effectively resist the impact of external forces such as strong winds and improve the structural safety of the curtain wall system. 3. Convenient maintenance: The decorative strip adopts a detachable elastic snap-fit structure. The combined curtain wall panel is fixed to the inner and outer frames by clamping screws. If the curtain wall panel is damaged in the future, the decorative strip and clamping screws can be quickly removed, the curtain wall panel can be replaced and reassembled, without the need to dismantle a large area of the curtain wall structure, reducing maintenance costs and construction difficulty. 4. Excellent sealing performance: The protruding part of the protective frame is interference-fitted with the slot, and the decorative strip covers the splicing gap. The elastic material of the protective frame and the decorative strip can adapt to a certain deformation, effectively preventing rainwater, dust and other impurities from entering the curtain wall and improving the sealing performance of the curtain wall. 5. Long service life: The protective frame covers the edge of the curtain wall panel, which can avoid the problem of the curtain wall panel cracking caused by thermal expansion and contraction. At the same time, it plays a buffer protection role for the curtain wall panel. Each component is detachable and easy to replace aging parts later, thus extending the service life of the entire curtain wall system. 6. High adaptability: The curtain wall panels can be made of insulation board or tempered glass, which can be adapted to the decoration and use needs of different buildings. The fasteners adopt expansion sleeve connection, which can be adapted to the wall of different building materials and has a wide range of applications. Attached Figure Description

[0021] Furthermore, in the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0022] In this invention, unless otherwise explicitly specified and limited, the terms "set," "socket," "connect," "through," and "plug-in" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
[0023] See Figure 1 and Figure 2 The prefabricated unitized curtain wall system shown includes, Fastener 1 is installed on the exterior wall of the building in a rectangular array. Positioning component 2 is fixedly installed at the end of the fixing component 1; The combined curtain wall panel 3 is installed and positioned by the positioning member 2, and the back of the combined curtain wall panel 3 is limited by the fixing member 1; Decorative clip 4, which is detachably installed between two adjacent combined curtain wall panels 3.
[0024] The installation method is as follows: This device is installed layer by layer from top to bottom. During installation, the bottommost fixing part 1 is installed first, and then the positioning part 2 is installed at the end of the fixing part 1.
[0025] Then, the combined curtain wall panel 3 is clamped between the fixing member 1 and the positioning member 2, and the positioning member 2 is further locked.
[0026] Install the second layer of fastener 1, then place the positioning piece 2 from top to bottom between the adjacent combined curtain wall panels 3, corresponding to the fastener 1, and assemble and tighten the positioning piece 2 and the fastener 1.
[0027] Repeat the above steps until the installation of the combined curtain wall panel 3 for the entire wall is completed.
[0028] Then, attach the decorative clip 4 between the adjacent combined curtain wall panels 3 to complete the entire installation.
[0029] After installation, the combined curtain wall panel 3 is firmly locked between the positioning pieces 2 arranged in a rectangular array and cannot be loosened.
[0030] See Figure 2 As shown, the fastener 1 includes a threaded portion 11 and an end portion 12. The threaded portion 11 is used to connect with the expansion sleeve, and a threaded hole 13 is provided at the axial center of the end portion 12. The end portion 12 is used to support the rear end face of the combined curtain wall panel 3.
[0031] In the above technical solution, the installation position of the threaded part 11 is first determined, then a hole is drilled on the surface of the wall using a drilling device, and an expansion sleeve is inserted. The threaded part 11 is then screwed in along the expansion sleeve until the end 12 is pressed against the surface of the wall.
[0032] A stop shim 14 is provided between the end 12 and the combined curtain wall panel 3.
[0033] The retaining shim 14 can compensate for the installation gap, making the installation stability of the combined curtain wall panel 3 higher.
[0034] See Figure 2As shown, the positioning component includes a clamping plate 21 and a positioning plate 22, which are integral. The positioning plate 22 is cross-shaped, and a stepped hole 23 corresponding to the threaded hole 13 is provided in the middle of the positioning plate 22. A long screw 24 is screwed into the stepped hole 23. The long screw 24 passes through the stepped hole 23 and is screwed into the threaded hole 13 to fix the clamping plate 21. The clamping plate 21 is clamped in the combined curtain wall panel 3, and the combined curtain wall panel 3 is positioned by the positioning plate 22.
[0035] In the above technical solution, the clamping plate 21 is clamped inside the combined curtain wall panel 3 after installation, thereby preventing the combined curtain wall panel 3 from falling off. Secondly, the positioning plate 22 is used to ensure that the spacing between adjacent combined curtain wall panels 3 is consistent, eliminating the need for manual assembly and alignment, making installation more convenient.
[0036] See Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the combined curtain wall panel 3 includes an inner frame 31, an outer frame 32, a curtain wall panel 33, and a protective frame 34. Rectangular grooves 35 are correspondingly provided on the opposite surfaces of the inner frame 31 and the outer frame 32. The protective frame 34, after elastic deformation, covers the edge of the curtain wall panel 33. The protective frame 34 is installed between the inner frame 31 and the outer frame 32 and is embedded in the rectangular groove 35. A clamping screw 36 is screwed into the outer end face of the outer frame 32 and screwed into the inner frame 31 to clamp the protective frame 34. When the protective frame 34 is clamped, a slot 37 is formed between the inner frame 31 and the outer frame 32. The clamping plate 21 is clamped in the slot 37. The positioning plate 22 is located at the top corner of the outer frame 32 and limits the adjacent installed outer frame 32. The inner frame 31 is clamped and fixed by the clamping plate 21 and the end plate 12.
[0037] In the above technical solution, the assembly of the inner frame 31, the outer frame 32 and the curtain wall panel 33 is completed on the ground.
[0038] When using glass curtain wall panels, considering the issue of thermal expansion and contraction, in order to prevent the edges of the glass curtain wall panels from cracking under pressure, this device includes an elastic protective frame 34 fitted over the outside of the curtain wall panel 33.
[0039] The protective frame 34 can deform elastically to protect the edges of the curtain wall panel 33, greatly reducing the risk of breakage when using tempered glass curtain wall panels.
[0040] Secondly, the protective frame 34 increases the sealing of the installation, eliminating the need for applying sealant.
[0041] The use of an inner frame 31 and an outer frame 32 for clamping avoids the problem of curtain wall panel 33 falling off, and the curtain wall panel 33 has a larger pressure-bearing area, making the clamping and fixing more stable.
[0042] The slot 37 formed by assembling the inner frame 31 and the outer frame 32 is used to cooperate with the card plate 21, so that the device can withstand strong winds and avoid falling off after assembly.
[0043] In the later stages, when it is necessary to replace the damaged curtain wall panel 33, simply remove the decorative clip 4 and unscrew the clamping screw 36 to remove the curtain wall panel 33 for replacement. At this time, the inner frame 31 remains in a clamped state to ensure the accuracy of the position during the later reinstallation.
[0044] See Figure 6 and Figure 7 As shown, the rear end of the decorative strip 4 is provided with a T-shaped elastic block 41. After the elastic block 41 is elastically deformed, it is inserted into the gap between the adjacent outer frame 32. After being inserted, the elastic block 41 elastically recovers between the adjacent slots 37, so that the decorative strip 4 is fixed.
[0045] Decorative clip 4 is made of elastic rubber to increase sealing during installation.
[0046] The two ends of the decorative strip 4 are V-shaped so that the four decorative strips 4 can be effectively closed when they touch at the ends.
[0047] The installation method using elastic clips 41 is easy to install and facilitates later maintenance.
[0048] The curtain wall panel 33 is an insulation board or a tempered glass panel.
[0049] See Figure 6 As shown, the outer side of the protective frame 34 is provided with a protruding part 341, which is interference-fitted into the slot 37.
[0050] The protruding part 341 can form a tight fit within the slot 37, further increasing the sealing performance during assembly.
[0051] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
