Description

Technical Field

[0001] This invention relates to the field of building curtain walls, and in particular to a prefabricated zigzag curtain wall system. Background Technology

[0002] Adding a curtain wall to the exterior of a building can enhance its quality and aesthetics. Conventional curtain wall types are mainly divided into unitized curtain walls and component curtain walls. Unitized curtain walls offer high processing and installation quality, fast construction speed, and short construction period, but they are also costly. Component curtain walls, on the other hand, offer flexible on-site construction and lower cost, but require more on-site work and have lower construction efficiency.

[0003] In summary, there is currently a lack of curtain wall structures that are fast to construct, low in cost, and require minimal work. Furthermore, current curtain wall facade cleaning typically involves vertical workers operating from high-rise buildings, which is inefficient and unsafe. Summary of the Invention

[0024] Example 1

[0025] like Figures 1-8 As shown in the figure, the prefabricated folded curtain wall system proposed in this embodiment includes a curtain wall device and a cleaning device. The cleaning device can clean the outer surface of the curtain wall device by spraying water and accelerate the drying of water by air jet. Compared with the existing method of cleaning from high altitude by Spider-Man, it is safer and more efficient.

[0026] Multiple curtain wall assemblies are arranged vertically side-by-side, including multiple horizontally arranged curtain wall mechanisms. Each horizontally arranged curtain wall mechanism constitutes one curtain wall assembly. These multiple sets of curtain wall assemblies are then aligned and installed at different heights to cover the building facade. The curtain wall mechanism includes stone panels, glass panels 8, and curtain wall components. The stone panels are installed on the curtain wall components. The glass panels 8 are insulated laminated glass, installed between adjacent curtain wall components. The stone panels and glass panels 8 are staggered, and the angle between them is obtuse, meaning they are arranged in a zigzag pattern.

[0027] like Figure 2As shown, the curtain wall assembly includes two vertically staggered main keels 1, a secondary keel 2 connecting the two main keels 1, a mounting base 4 mounted on the secondary keel 2, a stone panel mounted on the mounting base 4, and two bent steel channels 6 welded to the outer surfaces of the two main keels 1 respectively. A fiberglass support block 7 located at the bottom of the bent steel channel 6 is welded to the outer surface of the main keel 1. The glass panel 8 is mounted inside the bent steel channel 6 and above the fiberglass support block 7. The stone panels include a wider stone panel 51 and a narrower stone panel 52, which are installed aligned, creating a primary and secondary distinction for aesthetic appeal. Both are mounted to the secondary keel 2 via the mounting base 4. Specifically, the mounting base 4 includes a hanging base 41 bolted to the secondary keel 2 and a hanging clip 42 embedded in the hanging base 41. The hanging clip 42 is then fastened to the back of the stone panel.

[0028] like Figure 2 As shown, the inner sides of the two main keels 1 in the same curtain wall assembly are welded with transition steel plates 3, and the secondary keel 2 is welded to the transition steel plates 3. Waterproof aluminum plates 9 are installed on the outer sides of the main keels 1, secondary keels 2, transition steel plates 3, and mounting bases 4 to effectively waterproof the curtain wall. Insulation cotton is installed between the main keels 1 and secondary keels 2, located inside the waterproof aluminum plates 9, to improve the insulation effect.

[0029] The curtain wall construction process is as follows: The processing plant cuts the main and secondary keels to size according to the design data, then drills the process holes according to the positioning. Next, it processes the transition steel plate 3 of the secondary keel 2, the bent steel channel 6 for installing the glass, and the fiberglass support block 7. Finally, it processes the stone hanging bracket base 41 and the hanging bracket 42. Once all the processed parts are ready, along with the waterproof aluminum plate 9 purchased from other suppliers, and accessories such as insulation cotton and bolts, the curtain wall assembly is ready. Finally, according to the assembly process drawing, the main and secondary keels are welded together using the transition steel plate 3. The bent steel channel 6 and the fiberglass support block 7 are then welded to the main keel 1. The waterproof aluminum plate 9 is then fixed to the outer surface of the curtain wall assembly with screws. Insulation cotton is installed on the back of the waterproof aluminum plate 9. Finally, the processed stone hanging bracket base 41 is bolted through the waterproof aluminum plate 9 and fixed to the secondary keel 2. At this point, the curtain wall assembly is complete. According to the actual construction plan, the curtain wall components were transported to the site in sequence. On-site construction workers used hoisting methods to install the curtain wall components into place. Simultaneously, the stone panels, processed at the stone factory and equipped with stone hangers 42 and adjusting screws, were sent to the site. On-site construction workers, based on the stone codes, sequentially hung the hangers 42 onto the stone hanger bases 41 of the curtain wall components and adjusted them into place. Finally, the glass panels 8, processed at the glass factory, were directly sent to the site. On-site construction workers installed the glass panels 8 between two adjacent sets of curtain wall components, and finally sealed them with sealant, completing the final process.

[0030] The cleaning equipment is installed on the roof of the building. It includes a water tank 10 and multiple sets of cleaning devices arranged horizontally side-by-side. The top of the water tank 10 is sloped, and a filter screen 11 is installed at an angle, allowing rainwater to pass through the filter screen 11 and be stored inside. The filter screen 11 prevents airborne debris from entering the water tank 10. Additionally, when cleaning stone and glass panels 8 is required, water can be added to the water tank 10 via a water pump. The cleaning device includes a fixed base 12, two sets of cleaning components, a hanger 31 mounted on the cleaning components, a flexible hose 15 for suspending the hanger 31, a water supply pipe 151 and an air supply pipe 152 threaded inside the flexible hose 15, a winding roller 13 rotatably mounted on the fixed base 12 and wound around the flexible hose 15, and a power mechanism that drives the winding roller 13 to rotate and alternately supply water to the water supply pipe 151 and air to the air supply pipe 152. Both the fixed base 12 and the water tank 10 are fixedly installed on the roof of the building. Each cleaning unit is used to clean multiple vertically arranged stone and glass panels 8 below. The number of cleaning units depends on the number of curtain wall mechanisms in each curtain wall assembly. The two cleaning units are staggered and located on the outside of the stone and glass panels 8 respectively, with an obtuse angle between them. Each cleaning unit includes a water spray unit connected to a water supply pipe 151 and an air jet unit connected to an air supply pipe 152. The water spray unit sprays water onto the stone and glass panels 8 for cleaning, while the air jet unit accelerates the drying of water on the panels, preventing excessive dust from quickly adhering to the panel surface due to water droplets.

[0031] like Figure 5 As shown, the water spray assembly includes a hollow inner drainage plate 291 and an array of spray heads 2911 connected to the drainage plate 291. Multiple spray heads 2911 spray water onto the stone and glass panels 8, providing a large spray range and effectively covering the panels. A water distribution pipe 281 connects the drainage plate 291 and the water supply pipe 151, diverting water from the supply pipe 151 to two drainage plates 291 on either side. The spray heads 2911 on the two drainage plates 291 are used to spray water onto the stone and glass panels 8 respectively. When the hanger 31 is suspended via the hose 15, and both cleaning assemblies spray water or air simultaneously, there is minimal swaying between the two sets of cleaning assemblies. This is because the overall distribution of the two sets of cleaning assemblies resembles the obtuse angle distribution of the stone and glass panels 8, preventing the cleaning assemblies from tipping over. It is best to clean the panels in windless or low-wind conditions.

[0032] The jet assembly includes an inner hollow exhaust plate 292 and an array of jet heads 2921 connected to the exhaust plate 292. A gas distribution pipe 282 connects the exhaust plate 292 and the gas supply pipe 152, diverting the gas supplied by the gas supply pipe 152 to the two exhaust plates 292 and spraying it onto the panel surface through multiple jet heads 2921 for accelerated drying of water. The exhaust plate 292 is located on top of the drainage plate 291. When the hanger 31 is lowered, water is first sprayed onto the panel through the water spray head 2911, and then air is blown onto the panel through the jet heads 2921 for drying.

[0033] Multiple flexible baffles 30 are arranged side-by-side at the lower part of the drainage plate 291. The length of the flexible baffles 30 is greater than the length of the spray head 2911 and the jet head 2921. When the cleaning component shakes, the flexible baffles 30 prevent the cleaning component from causing large impacts to the panel.

[0034] like Figure 4 As shown, two guide wheels are rotatably mounted on the mounting base 12. The outer circumference of the guide wheels has an annular groove, and a channel is formed between the two guide wheels for the flexible hose 15 to pass through. The two guide wheels are used to support the structure suspended below the flexible hose 15 on the outside of the building, allowing it to be lowered from the outside of the curtain wall for cleaning the stone and glass panels 8.

[0035] This embodiment combines the advantages of both unitized and component-based curtain walls. It employs a prefabricated structure, with the main components prefabricated and assembled in the factory before being delivered to the site. On-site installation requires only simple hoisting operations, resulting in a simple, efficient, and cost-effective installation. Furthermore, it can automatically clean the stone and glass panels 8 of the curtain wall using water and air sprays, offering high cleaning efficiency and enhanced safety.

[0036] Example 2

[0037] like Figures 1-8As shown, this embodiment proposes a prefabricated zigzag curtain wall system. Compared to Embodiment 1, in this embodiment, the power mechanism includes a rotating shaft 14 rotatably mounted on a fixed base 12 for mounting a winding roller 13, a mounting cover 32 and a pumping cylinder 19 mounted on the fixed base 12, a piston 22 slidably sealed within the pumping cylinder 19, a drive assembly drivenly connected to the rotating shaft 14 and the piston 22, and a pumping assembly for pumping water and air. The winding roller 13 has protruding plates at both ends, and a flexible hose 15 passes through one of the protruding plates. One end of the rotating shaft 14 has an insertion channel for a water pipe 151 and an air pipe 152 to pass through. One end of the insertion channel is connected to the end of the flexible hose 15, and an end cap 16 is provided at the outer end of the insertion channel. The water pipe 151 and the air pipe 152 are installed through the end cap 16. The water pipe 151 is centrally distributed on the end cap 16, and the air pipe 152 is eccentrically distributed on the end cap 16. The flexible hose 15 serves two purposes: firstly, it supports the hanger 31, and secondly, it is used to thread the water pipe 151 and the air pipe 152, protecting both pipes internally. Adhesive can be injected between the flexible hose 15, the water pipe 151, and the air pipe 152; the solidified adhesive layer separates the three, reducing wear and not affecting the unwinding or winding of the hoses. When the drive assembly rotates the shaft 14, the shaft 14 drives the winding roller 13 to rotate, which in turn winds the flexible hose 15. Unwinding the flexible hose 15 lowers the hanger 31, and winding the flexible hose 15 raises the hanger 31.

[0038] like Figure 6 and Figure 7 As shown, piston 22 divides the inner space of pumping cylinder 19 into a water chamber and an air chamber. The pumping assembly includes a water pumping pipe 20 and an inlet pipe 181 communicating with the water chamber, an air pumping pipe 21 and an inlet pipe 182 communicating with the air chamber, a bracket 121 mounted on mounting cover 32, and a fixed cylinder 17 mounted on bracket 121 and communicating with inlet pipe 181 and inlet pipe 182. The fixed cylinder 17 is rotatably and sealingly connected to rotating shaft 14. The water pumping pipe 20 is connected to water tank 10 and can pump water from water tank 10. A one-way valve 201 is installed on the water extraction pipe 20, which allows one-way flow to the water chamber. A one-way valve 211 is installed on the air extraction pipe 21, which allows one-way flow to the air chamber. A one-way valve 1811 is installed on the water inlet pipe 181, which allows one-way flow to the fixed cylinder 17. A one-way valve 1821 is installed on the air inlet pipe 182, which allows one-way flow to the fixed cylinder 17. The fixed cylinder 17 is connected to the water supply pipe 151 and the air supply pipe 152. Water and air are alternately supplied to the fixed cylinder 17 through the extraction cylinder 19. Water can flow to the water supply pipe 151, and air can flow to the air supply pipe 152. Thus, the cleaning components alternately spray water and air to effectively clean the stone panel and glass panel 8.

[0039] like Figure 6As shown, the mounting cover 32 is provided with vent holes. The drive assembly includes a motor 25 housed within the mounting cover 32, a crankshaft 26 rotatably mounted within the mounting cover 32 and connected to the output end of the motor 25, a connecting rod 24 rotatably connected at one end to the connecting rod journal of the crankshaft 26, a piston rod 23 rotatably connected to the other end of the connecting rod 24, a bevel gear 1 mounted at the end of the crankshaft 26, a mounting shaft 27 rotatably mounted on the mounting cover 32, bevel gear 2 and gear 1 rotatably mounted at both ends of the mounting shaft 27, and gear 2 coaxially mounted on the rotating shaft 14. The air inlet of the exhaust pipe 21 faces the motor 25, and can draw in the hot air generated by the motor 25 during operation, ultimately spraying the hot air onto the panel surface through the jet assembly to accelerate water drying. The output end of the motor 25 can rotate in both directions, driving the crankshaft 26 to rotate in both directions. Gear 2 meshes with gear 1, and bevel gear 2 meshes with bevel gear 1. The crankshaft 26 drives the bevel gear 2 to rotate via bevel gear 1. Bevel gear 2 drives gear 1 to rotate via mounting shaft 27. Gear 1 drives the rotating shaft 14 to rotate via gear 2, thereby enabling the forward and reverse rotation of the winding roller 13 for winding and unwinding the hose 15 and lifting or lowering the hanger 31. The piston rod 23 slides through one end of the delivery cylinder 19 and is connected to the piston 22 to drive the piston 22 to reciprocate. The crankshaft 26 drives the piston rod 23 to reciprocate via connecting rod 24.

[0040] Piston rod 23 drives piston 22 to reciprocate. When piston 22 slides to the left, the air chamber volume of the extraction cylinder 19 decreases and the water chamber volume increases. One-way valves 211 and 311 close, while one-way valves 201 and 4121 open. Water is drawn into the water chamber through the water extraction pipe 20, and air is supplied to the fixed cylinder 17 through the air inlet pipe 182. At this time, air can be sprayed onto the panel through the air jet assembly. When piston 22 slides to the right, the air chamber volume of the extraction cylinder 19 increases and the water chamber volume decreases. One-way valves 201 and 4121 close, while one-way valves 211 and 311 open. Air is supplied into the air chamber through the air extraction pipe 21, and water is supplied to the fixed cylinder 17 through the water inlet pipe 181. At this time, water can be sprayed onto the panel through the water spray assembly.

[0041] like Figure 7 and Figure 8As shown, the fixed cylinder 17 has a centrally located channel 171, an eccentrically located channel 2 172, and a connecting groove communicating with channel 2 172. A transition groove is formed between the end 16 and the end of the water supply pipe 151. The water supply pipe 151 is centrally located relative to the end 16 at the transition groove, and rotates the end 16 when the rotating shaft 14 rotates. The fixed cylinder 17 is rotatably and sealingly connected to the transition groove, connecting the water supply pipe 151 and one end of channel 171, maintaining communication between the water supply pipe 151 and channel 171. The inlet pipe 181 is connected to the other end of channel 171, thus maintaining communication with the water supply pipe 151, and finally sprays water onto the panel through the water spray assembly. The air supply pipe 152 is connected to channel 2 172 through the connecting groove, and channel 2 172 is connected to the air inlet pipe 182. The intake pipe 182, channel 2 172 and air delivery pipe 152 are all eccentrically distributed. The air delivered by the intake pipe 182 can be delivered to the air delivery pipe 152 through channel 2 172 and the connecting groove, and finally sprayed onto the panel through the jet assembly.

[0042] In this embodiment, the rotating shaft 14 is driven by the drive component to lift and lower the cleaning component, and the water and air are alternately pumped by the reciprocating sliding of the drive piston 22 to perform water spray cleaning and air jet drying treatment on the panel, which greatly improves the cleaning efficiency of the curtain wall.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
