Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy curtain walls, in particular to a telescopic, folding and linked aluminum alloy curtain wall structure. Background Art

[0002] The aluminum alloy curtain wall structure is a building exterior enclosure system that uses aluminum alloy profiles as a supporting frame and is constructed with curtain wall panels such as glass and metal plates. With its characteristics of light weight, high strength, good weather resistance, and high degree of assembly, it has gradually become the mainstream form of modern building facade design. A typical aluminum alloy curtain wall usually consists of a grid-like skeleton composed of columns and beams, which is fixed to the main body of the building through connectors, and curtain wall panels are embedded between the skeletons to form a continuous facade. Some improved structures will integrate opening fans or sunshade components to meet functional requirements such as ventilation and sunshade. However, in actual applications, the existing aluminum alloy curtain wall structure still has significant defects in heat exchange efficiency and expansion flexibility:

[0003] The ventilation openings of traditional curtain walls mostly adopt a flat opening or push-pull design. The opening angle and expansion area are limited by the mechanical structure, resulting in insufficient cross-sectional area for air circulation and difficulty in achieving rapid heat exchange. Especially in scenarios requiring large-volume ventilation, the heat convection efficiency is low, affecting the indoor temperature control effect. The ventilation opening layout of most curtain walls lacks convection optimization design and fails to effectively utilize the natural convection law of hot air rising and cold air sinking, resulting in disordered airflow organization and difficulty in improving the heat exchange rate. The horizontal and vertical splicing of existing curtain wall units mostly relies on bolt fastening or welding. Precise alignment is required during installation and the sealing process is complex, making it difficult to achieve rapid disassembly and seamless expansion, which restricts the overall scalability and construction efficiency of the curtain wall system. The adjustment of sunshade components and ventilation components mostly relies on manual operation or independent drive devices. There is a lack of linkage control mechanism, which cannot achieve coordinated action of multiple components, resulting in insufficient adjustment accuracy and response speed.

[0004] The above problems limit the further application of aluminum alloy curtain walls in modern buildings and urgently need to be solved through improvements in structure and installation methods. Summary of the Invention

[0031] Limiting slots are provided on the front and rear sides of the fixed frame.

[0032] In a preferred solution, the fixing frame is provided on both sides with:

[0033] A rotating rod provided throughout;

[0042] In the preferred solution, a fixed plate with a plug-in block is provided at the top of the U-shaped mounting groove, and a fixed plate with a plug-in groove is provided at the bottom, and the contact surface between the plug-in block and the plug-in groove is provided with a chamfered structure; the rack includes two racks respectively arranged at the upper end of the front side and the lower end of the rear side of the U-shaped mounting groove, and the two racks form a differential transmission with the corresponding gears.

[0043] In a preferred solution, the contact surface between the sealing sheet and the sealing groove is provided with an elastic sealing layer, and the cross-sectional shape of the plug-in sheet is adapted to the plug-in cavity of the connecting block.

[0044] The present invention also provides a construction method for a telescopic folding linkage aluminum alloy curtain wall structure, comprising the following steps:

[0045] S1. Horizontal Splicing and Extension: Install two sets of U-shaped mounting slots parallel to each other at predetermined locations within the main building structure, performing horizontal splicing. Insert the sealing sheet of the connector into the sealing slot of the adjacent U-shaped mounting slot. Align the plug-in posts of the connector and insert them into the snap-in slots of the connecting block. Push the second snap-in block so that the snap-in protrusions mechanically engage with the first snap-in block. This completes the positioning and locking of the connector and the connecting block.

[0046] S2. Vertical splicing installation: Align the upper U-shaped mounting block with the lower unit's slot. Lower the upper unit in the direction of gravity, using the chamfered bottom of the block to guide the unit. Once the block is fully inserted into the slot, a vertical load-bearing connection is formed.

[0047] S3. Curtain wall panel system installation: The fixed frame of the first curtain wall panel is installed between the two sets of U-shaped mounting grooves by fasteners; the limit block of the movable frame is embedded in the limit groove of the fixed frame to form a sliding fit; the splint and the movable frame establish a rigid connection;

[0048] S4. The micromotor is started, and the second synchronous wheel drives the third synchronous wheel via the second synchronous belt. The rotating rod drives the first synchronous wheel to rotate bidirectionally. The splint of the first synchronous belt pulls the second curtain wall panel along the limit groove in the opposite direction. The two sets of second curtain wall panels form a symmetrical displacement of unfolding / folding.

[0049] S5. During the displacement of the second curtain wall panel, the gear rotates along the meshing trajectory of the rack; the shaft drives the sunshade strip to form a continuous angular deflection; the first and second sunshades form an interlaced displacement within the sliding groove; the deflection angle of the sunshade strip and the displacement of the sunshade panels form a three-dimensional sunshade system.

[0050] Compared with the prior art, the advantages of the present invention are:

[0051] First, the present invention incorporates a bidirectionally foldable secondary curtain wall panel system, combined with vertically staggered heat exchange ports, to overcome the morphological limitations of traditional fixed curtain walls. When folded and unfolded, these panels form a convection channel that runs through the building facade. This optimizes airflow by utilizing the natural convection of hot air rising and cold air sinking, significantly improving passive heat exchange efficiency. This design creates a three-dimensional ventilation interface within a confined space, enhancing the curtain wall's climate-regulating capabilities and reducing reliance on mechanical ventilation systems.

[0052] Second, the present invention utilizes a hybrid drive system combining a rack and pinion differential drive with a synchronous belt. This system uses a single micromotor to coordinate the curtain wall's folding motion and shading angle adjustment, enabling automatic rotation of the shade strips during folding and unfolding, creating a dynamic shading system. This mechanical linkage surpasses the traditional independent control model of multiple actuators, significantly improving system response speed and coordinated movement.

[0053] Third, the present invention incorporates a splicing system based on chamfered guides for plug-in blocks and snap-on sealing components, enabling rapid expansion of curtain wall units. The combination of an elastic sealing layer and multiple snap-on structures ensures airtightness while creating a self-locking mechanical connection. This design breaks away from traditional bolt-on fastening methods, enabling seamless horizontal and vertical expansion of the curtain wall system. This significantly improves construction convenience and provides a technical foundation for the dynamic reconfiguration of building facades.

[0054] Fourth, the present invention deeply couples the folding mechanism with the pivoting sunshade strips, automatically optimizing the shading angle as the curtain wall unfolds. Combined with the slidably adjustable double-layer sunshade, this creates a three-dimensional, active and passive shading system. This design breaks away from traditional static shading by achieving a dynamic balance between shading efficiency and ventilation requirements, ensuring natural ventilation while controlling solar heat gain, thereby enhancing building comfort.

[0071] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0072] Reference Figure 1-10 As shown, the telescopic, foldable, and linked aluminum alloy curtain wall structure consists of a U-shaped mounting groove 1, a fixed plate 2, a plug-in block 3, a plug-in groove 4, a splicing assembly 5, and a curtain wall panel assembly. Two sets of U-shaped mounting grooves 1 are arranged parallel to each other. A chamfered plug-in block 3 is welded to the center of the top fixed plate 2, and a plug-in groove 4 is provided at the corresponding position of the bottom fixed plate 2. The connecting block 501 of the splicing assembly 5 is fixed to the outside of the U-shaped mounting groove 1 by bolts. The first snap-in blocks 502 on both sides are provided with snap-in grooves 503. The sealing piece 506 of the plug-in block 505 is inserted into the sealing groove 504 of the adjacent unit. The snap-in protrusion 508 of the second snap-in block 507 is snap-locked with the first snap-in block 502. The snap-in column 509 is inserted into the snap-in groove 503 to complete the horizontal splicing.

[0073] The fixed frame 601 of the first curtain wall panel 6 is bolted between the two sets of U-shaped mounting slots 1. A first sun visor 603 and a second sun visor 604 slide within the sliding slots 602 on either side. The front and rear stop slots 605 of the fixed frame 601 form a sliding engagement with the stop blocks 702 of the second curtain wall panel 7. A rotating rod 606 extends through both sides of the fixed frame 601. First synchronous pulleys 607, mounted on either end, are driven by a first synchronous belt 608. A clamping plate 613 is secured to the first synchronous belt 608 and connected to the movable frame 701. A micromotor 609 drives the second synchronous pulley 610, which in turn drives the third synchronous pulley 611 via the second synchronous belt 612, rotating the rotating rod 606.

[0074] The movable frame 701 of the second curtain wall panel 7 rotates within multiple shafts 703, with sunshade strips 704 secured to their outer circumferences. The ends of the shafts 703 extend through the movable frame 701 and connect to gears 705. These gears 705 differentially mesh with two racks 8 located at the upper front and lower rear ends of the U-shaped mounting slot 1. The angle of the sunshade strips 704 automatically adjusts with the movement of the movable frame 701. The differential drive ensures synchronous rotation of the sunshade strips 704 during folding and unfolding.

[0075] During the coordinated drive process, the micromotor 609 rotates the rotating rod 606 via the second synchronous belt 612. The first synchronous belt 608 drives the two side clamps 613 to move in opposite directions, causing the two sets of second curtain wall panels 7 to fold or unfold along the limiting grooves 605. As the movable frame 701 moves, the gear 705 rolls along the rack 8, driving the rotating shaft 703 to rotate, causing the sunshade strip 704 to angularly deflect. The elastic sealing layer on the contact surface between the sealing sheet 506 and the sealing groove 504 ensures airtightness in the splicing. The cross-sectional shape of the plug-in sheet 505 is fully compatible with the plug-in cavity of the connecting block 501.

[0076] In the vertical direction, the fast and convenient splicing of the curtain wall structure in the vertical direction is achieved through the adaptive connection between the plug-in block 3 and the plug-in slot 4. The bottom of the plug-in slot 4 is chamfered to facilitate the accurate insertion of the plug-in block 3, thereby improving the installation efficiency and reducing the installation difficulty. This connection method not only ensures the structural stability, but also allows the curtain wall structure to be flexibly expanded in the vertical direction according to the building requirements. The two sets of U-shaped installation grooves 1 are both provided with splicing components 5 on the outside. The first curtain wall panel 6 is fixedly connected in the middle between the two sets of U-shaped installation grooves 1. The second curtain wall panel 7, two groups of second curtain wall panels 7 are respectively arranged on the front and rear sides of the first curtain wall panel 6, and a rack 8 is fixedly connected to the inside of the U-shaped mounting groove 1 on the right side. The two racks 8 are respectively fixedly connected to the upper end of the front side and the lower end of the rear side of the U-shaped mounting groove 1. Glass curtain walls are installed inside the first curtain wall panel 6 and the second curtain wall panel 7. The glass curtain walls are both arranged on the water-facing side and the position of the glass curtain walls will not interfere with the normal rotation of the sunshade strip 704. When performing small-flow heat exchange, it is only necessary to slide the first sunshade 603 and the second sunshade 604 in the first curtain wall panel 6 relative to each other.

[0077] Specifically, the splicing assembly 5 includes a connecting block 501 and two sealing grooves 504. The connecting block 501 is fixedly connected to the middle of the outer side of the U-shaped mounting groove 1. The two sealing grooves 504 are respectively fixedly connected to the front and rear sides of the U-shaped mounting groove 1. The two sealing grooves 504 are respectively arranged on the front and rear sides of the connecting block 501. The front and rear ends of the connecting block 501 away from the U-shaped mounting groove 1 are fixedly connected to the first buckle block 502. The middle of the side of the first buckle block 502 away from the U-shaped mounting groove 1 is provided with a circular buckle groove 503. The connecting block 501 is fixed to the middle of the outer side of the U-shaped mounting groove 1, providing a core connection point for splicing. The design of the first buckle block 502 and the buckle groove 503 enables adjacent curtain wall structures to be tightly connected by buckling when the curtain wall structure is horizontally spliced. The connection is firm and reliable, and can effectively resist external loads such as wind and earthquakes, ensuring the safety of the overall curtain wall structure.

[0078] Specifically, the splicing component 5 also includes a plug-in piece 505, and the front and rear ends of the plug-in piece 505 are fixedly connected to a sealing piece 506, which is inserted into the sealing groove 504. The front and rear ends of the plug-in piece 505 are fixedly connected to two groups of second buckling blocks 507 on the inner side of the sealing piece 506. The plug-in piece 505 is a key component for connecting adjacent curtain wall structures. The buckling cooperation between the second buckling block 507, the buckling protrusion 508 and the first buckling block 502 further enhances the stability of the horizontal splicing. This buckling method is simple to operate and easy to install. It can quickly complete the horizontal expansion of the curtain wall structure and improve construction efficiency. The connection method between the connecting block 501 and the plug-in piece 505 is "connecting block 501-plug-in piece 505-connecting block 501", that is, a plug-in piece 505 is set between the two connecting blocks 501. What is shown in the figure is actually the connection method between the plug-in piece 505 and the connecting block 501, not a specific installation method.

[0079] Specifically, the four groups of second snap-in blocks 507 are each provided with a snap-in protrusion 508 on the side away from the plug-in piece 505, the snap-in protrusion 508 is adapted to the first snap-in block 502, and the first snap-in block 502 is snap-in and snap-in between the snap-in protrusion 508 and the plug-in piece 505, and the plug-in piece 505 is fixedly connected with a plug-in column 509 on both sides of the middle part, and the plug-in column 509 is plugged into the inside of the snap-in groove 503, which provides additional positioning and fixing for the splicing structure, ensuring that the adjacent curtain wall structures are accurately positioned after splicing, without offset or shaking, and further improving the overall stability and sealing of the curtain wall structure.

[0080] Specifically, the first curtain wall panel 6 includes a fixed frame 601, which is fixedly connected to the middle position between the two groups of U-shaped mounting grooves 1 by bolts. Two groups of limit grooves 605 are provided on the front and rear sides of the fixed frame 601, and sliding grooves 602 are provided on the upper and lower ends of the inner side of the fixed frame 601. The first sun visor 603 and the second sun visor 604 are slidingly connected between the two groups of sliding grooves 602. The first sun visor 603 and the second sun visor 604 are staggered with each other in the front and back. The design of the sliding grooves 602 enables the first sun visor 603 and the second sun visor 604 to slide flexibly in the fixed frame 601. By adjusting their relative positions, the shading area and shading effect can be flexibly changed according to different sunlight angles and intensities, thereby achieving precise control of indoor light and improving the comfort of the indoor environment.

[0081] The left and right sides of the fixed frame 601 are rotatably connected to the rotating rods 606, and the outer surfaces of the two rotating rods 606 are fixedly connected to the first synchronous wheels 607. The first synchronous belt 608 is transmission-connected between the two first synchronous wheels 607. The front belt and the rear belt of the first synchronous belt 608 are fixedly connected with a clamping plate 613. The two clamping plates 613 are respectively fixedly connected to the two second curtain wall panels 7. Through the transmission mechanism of the rotating rod 606, the first synchronous wheel 607 and the first synchronous belt 608, the two second curtain wall panels 7 can be synchronously driven to move in opposite directions to realize the folding linkage function of the curtain wall structure. This transmission method has a compact structure and smooth transmission, can ensure the coordinated movement of the two second curtain wall panels 7, and improves the operational stability and reliability of the curtain wall structure. The clamping plate 613 is fixedly connected to the second curtain wall panel 7, which ensures the effectiveness of the transmission, so that the second curtain wall panel 7 can move accurately according to the design requirements.

[0082] Specifically, a micro motor 609 is fixedly connected to the bottom right side of the fixed frame 601. The output shaft end of the micro motor 609 is fixedly connected to a second synchronous pulley 610 via a coupling. A third synchronous pulley 611 is fixedly connected to the outer surface of the right lower end rotating rod 606 on the left side of the first synchronous pulley 607. A second synchronous belt 612 is connected between the third synchronous pulley 611 and the second synchronous pulley 610. The micro motor 609 serves as a power source. Through the transmission of the second synchronous pulley 610, the second synchronous belt 612, and the third synchronous pulley 611, the rotation of the rotating rod 606 can be precisely controlled, thereby achieving automatic control of the movement of the second curtain wall panel 7. This automated control method is easy to operate and improves the ease of use of the curtain wall structure. At the same time, the synchronous belt drive has the advantages of accurate transmission ratio, smooth operation, and low noise, which can ensure the stability and comfort of the curtain wall structure during operation.

[0083] Specifically, the second curtain wall panel 7 includes a movable frame 701. Two limit blocks 702 are fixedly connected to the side of the movable frame 701 close to the first curtain wall panel 6. The two limit blocks 702 are respectively slidably connected to the inside of the two groups of limit grooves 605. The movable frame 701 is the main structure of the second curtain wall panel 7. The limit blocks 702 cooperate with the limit grooves 605 on the fixed frame 601 to ensure that the movable frame 701 can move stably along a predetermined trajectory during movement, thereby ensuring the operating accuracy and sealing of the curtain wall structure. This design prevents the second curtain wall panel 7 from shaking or deflecting during movement, thereby improving the overall performance of the curtain wall structure.

[0084] Specifically, a plurality of rotating shafts 703 are rotatably connected inside the movable frame 701, and a sunshade strip 704 is fixedly connected to the outside of the rotating shaft 703. The right end of the rotating shaft 703 passes through the right side wall of the movable frame 701 and is fixedly connected to a gear 705 that drives the rotating shaft 703 to rotate. The gear 705 is engaged with the rack 8. The racks 8 are respectively arranged on the upper and lower sides of the first curtain wall panel 6 and are staggered with each other. In cooperation with the gear 705, the angle of the sunshade strip 704 is automatically adjusted during the movement of the second curtain wall panel 7.

[0085] Rack 8 comprises two racks, one mounted at the front upper end and the other at the rear lower end of the U-shaped mounting slot 1. The front upper rack and the rear lower rack respectively mesh with gears 705 at the ends of the second curtain wall panel 7. The two racks are asymmetrically arranged along the U-shaped mounting slot 1. When the second curtain wall panel 7 moves, the gears 705 roll synchronously on the front upper and rear lower racks. The spatially offset arrangement of the two racks generates differential rotation of the gears 705 during movement, which in turn drives the sunshade strips 704 to produce angular deflection due to the transmission drive shaft 703.

[0086] This design cleverly utilizes the movement of the second curtain wall panel 7, and can adjust the angle of the sunshade strip 704 without an additional drive device. It has a simple structure and low cost, while improving the intelligence and automation level of the curtain wall structure. The sunshade strip 704 can automatically adjust the angle according to the moving position to achieve dynamic shielding of sunlight. This design of automatically adjusting the sunshade angle can provide the best shading effect according to different sunlight exposure conditions, improve the comfort of the indoor environment, and reduce indoor energy consumption.

[0087] The telescopic folding linkage aluminum alloy curtain wall structure designed by the present invention is installed and constructed according to the following steps:

[0088] S1. Horizontal Splicing Extension: Place two sets of U-shaped mounting grooves 1 parallel to each other at predetermined locations within the main building structure and perform horizontal splicing. Insert the sealing piece 506 of the plug-in piece 505 into the sealing groove 504 of the adjacent U-shaped mounting groove 1. Align and insert the plug-in post 509 of the plug-in piece 505 into the buckle groove 503 of the connecting block 501. Push the second buckle block 507 so that the buckle protrusion 508 forms a mechanical buckle with the first buckle block 502. This completes the positioning and locking of the plug-in piece 505 and the connecting block 501.

[0089] S2 vertical splicing installation: the upper U-shaped mounting slot 1 of the plug block 3 is aligned with the plug slot 4 of the lower unit; lower the upper unit along the direction of gravity, using the bottom chamfered structure of the plug block 3 to achieve the guide positioning; the plug block 3 is fully inserted into the plug slot 4 to form a vertical load-bearing connection;

[0090] S3 curtain wall panel system installation: The first curtain wall panel 6 fixed frame 601 is installed between two sets of U-shaped mounting grooves 1 by fasteners; the movable frame 701 limit block 702 is embedded in the fixed frame 601 limit groove 605 to form a sliding fit; the splint 613 establishes a rigid connection with the movable frame 701;

[0091] S4. Start the micro motor 609, the second synchronous wheel 610 drives the third synchronous wheel 611 through the second synchronous belt 612; the rotating rod 606 drives the first synchronous wheel 607 to rotate bidirectionally; the first synchronous belt 608 of the splint 613 pulls the second curtain wall panel 7 along the limit groove 605 to move in the opposite direction; the two sets of second curtain wall panels 7 form a symmetrical displacement of unfolding / folding;

[0092] S5. During the displacement of the second curtain wall panel 7, the gear 705 rotates along the meshing trajectory of the rack 8; the rotating shaft 703 drives the sunshade strip 704 to form a continuous angle deflection; the first sunshade 603 and the second sunshade 604 form a staggered displacement in the sliding groove 602; the deflection angle of the sunshade strip 704 and the displacement of the sunshade form a three-dimensional sunshade system.

[0093] Example 1. This example provides a specific method for constructing and installing a telescopic, folding, and linked aluminum alloy curtain wall structure: two sets of U-shaped mounting grooves 1 are installed at designated locations of the building. If it is necessary to expand multiple curtain wall structures horizontally, first place the two curtain wall structures in parallel, then insert the sealing sheet 506 on the plug-in sheet 505 into the sealing groove 504 of the adjacent U-shaped mounting groove 1, align the plug-in column 509 on the plug-in sheet 505 and insert it into the buckle groove 503 in the connecting block 501, and at the same time, buckle the first buckle block 502 between the buckle protrusion 508 of the second buckle block 507 and the plug-in sheet 505 to complete the splicing of multiple curtain wall structures horizontally. When performing vertical splicing, it is only necessary to plug the plug-in block 3 in another curtain wall structure into the plug-in groove 4 in the curtain wall structure.

[0094] When it is necessary to adjust the position of the second curtain wall panel 7 for large-flow heat exchange, the micro motor 609 is started, and the output shaft of the micro motor 609 drives the second synchronous wheel 610 to rotate. The second synchronous wheel 610 drives the third synchronous wheel 611 to rotate through the second synchronous belt 612. The third synchronous wheel 611 is fixed to the rotating rod 606 at the lower end on the right side, thereby rotating the rotating rod 606, and the first synchronous wheel 607 on the rotating rod 606 rotates accordingly. The two first synchronous wheels 607 are driven by the first synchronous belt 608, and the clamping plate 613 on the first synchronous belt 608 drives the two second curtain wall panels 7 to move along the limiting groove 605. Since the belts on both sides of the first synchronous belt 608 move in opposite directions when rotating, the two second curtain wall panels 7 are driven to move in the same direction through the two clamping plates 613, that is, one second curtain wall panel 7 moves downward and the other second curtain wall panel 7 moves upward, and then reach the same position as the first curtain wall panel 6, thereby allowing the room to perform large-flow heat exchange with the outside world.

[0095] During the closing process, since the two racks 8 are respectively arranged on the upper and lower sides of the first curtain wall panel 6 and are offset from each other, when the second curtain wall panel 7 is moving during the sealing action, the gear 705 will roll on the rack 8 as the second curtain wall panel 7 moves, thereby driving the rotating shaft 703 to rotate, and the sunshade strip 704 on the outside of the rotating shaft 703 rotates accordingly. In this way, the angle of the sunshade strip 704 can be automatically adjusted according to the angle and intensity of sunlight to achieve the sunshade function. When the sunshade effect of the first curtain wall panel 6 needs to be adjusted, the first sunshade 603 and the second sunshade 604 are slid in the sliding groove 602 manually or through other driving devices. Since they are offset from each other in the front and back, the sunshade area and sunshade effect can be changed by adjusting their relative positions, and cooperate with the sunshade strip 704 on the second curtain wall panel 7 to achieve a better sunshade function.
