Description

Technical Field

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

[0002] The aluminum alloy curtain wall structure is a building 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 a 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 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 shading. However, in actual applications, the existing aluminum alloy curtain wall structure still has significant defects in heat exchange efficiency and expansion flexibility: The ventilation openings of traditional curtain walls are mostly designed with flat openings or push-pull designs. The opening angle and expansion area are limited by the mechanical structure, resulting in insufficient cross-sectional area for air circulation, making it difficult to achieve rapid heat exchange. Especially in scenarios where large-volume ventilation is required, the heat convection efficiency is low, affecting the indoor temperature control effect. The vent 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, which requires precise alignment during installation and complex sealing treatment, making it difficult to achieve rapid disassembly and seamless expansion, restricting 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, lacks a linkage control mechanism, and cannot achieve coordinated action of multiple components, resulting in insufficient adjustment accuracy and response speed.

Specific embodiments

[0020] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and those skilled in the art can think of other obvious variations.

[0021] Referring to Figures 1-10 As shown, the retractable and foldable linkage aluminum alloy curtain wall structure is composed of a U-shaped mounting groove 1, a fixing plate 2, an insertion block 3, an insertion slot 4, a splicing component 5 and a curtain wall panel component. Two groups of U-shaped mounting grooves 1 are arranged in parallel left and right. A chamfered insertion block 3 is welded in the center of the top fixing plate 2, and an insertion slot 4 is opened at the corresponding position of the bottom fixing plate 2. The connecting block 501 of the splicing component 5 is fixed to the outside of the U-shaped mounting groove 1 by bolts. Buckling grooves 503 are opened in the first buckling blocks 502 on both sides thereof. The sealing piece 506 of the insertion piece 505 is inserted into the adjacent unit sealing groove 504. The buckling protrusion 508 of the second buckling block 507 forms a buckling lock with the first buckling block 502, and the insertion column 509 is embedded in the buckling groove 503 to complete the horizontal splicing.

[0022] The fixed frame 601 of the first curtain wall panel 6 is installed between two groups of U-shaped installation grooves 1 by bolts, and the first sunshade panel 603 and the second sunshade panel 604 are slidably arranged in the sliding grooves 602 on both sides. The limiting grooves 605 on the front and rear sides of the fixed frame 601 form a sliding fit with the limiting blocks 702 of the second curtain wall panel 7. The rotating rod 606 penetrates through both sides of the fixed frame 601, and the first synchronous pulleys 607 sleeved at both ends are linked by the first synchronous belt 608. The clamping plate 613 is fixed to the first synchronous belt 608 and is connected to the moving frame 701. The micro motor 609 drives the second synchronous pulley 610, and drives the third synchronous pulley 611 through the second synchronous belt 612 to realize the rotation of the rotating rod 606.

[0023] A plurality of rotating shafts 703 are rotatably arranged in the moving frame 701 of the second curtain wall panel 7, and the sunshade strips 704 are fixed to the outer circumference of the rotating shafts 703. The ends of the rotating shafts 703 penetrate through the moving frame 701 to connect the gears 705, and the gears 705 form a differential meshing with two rack units at the upper end of the front side and the lower end of the rear side of the U-shaped installation groove 1. The angle of the sunshade strips 704 is automatically adjusted with the displacement of the moving frame 701, and the differential transmission cooperation ensures the synchronous rotation of the sunshade strips 704 during the folding and unfolding process.

[0024] During the linkage drive process, the micro motor 609 drives the rotating rod 606 to rotate through the second synchronous belt 612, and the first synchronous belt 608 drives the clamping plates 613 on both sides to move in the opposite direction, so that the two groups of second curtain wall panels 7 are folded or unfolded along the limiting grooves 605. When the moving frame 701 is displaced, the gear 705 rolls along the rack 8 to drive the rotating shaft 703 to rotate, and the sunshade strip 704 generates an angular deflection. The elastic sealing layer arranged on the contact surface between the sealing piece 506 and the sealing groove 504 ensures the airtightness of the splicing, and the cross-sectional shape of the plug-in piece 505 is completely adapted to the plug-in cavity of the connecting block 501.

[0025] Vertically, through the fitting connection between the plugging block 3 and the plugging slot 4, the rapid and convenient splicing of the curtain wall structure in the vertical direction is realized. A chamfer is provided at the bottom of the plugging slot 4 to facilitate the accurate insertion of the plugging block 3, 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. Splicing components 5 are provided on the outer sides of both groups of U-shaped installation grooves 1. A first curtain wall panel 6 is fixedly connected in the middle between the two groups of U-shaped installation grooves 1. Second curtain wall panels 7 are provided on both the upper and lower sides between the two groups of U-shaped installation grooves 1. The two second curtain wall panels 7 are respectively arranged on the front and rear sides of the first curtain wall panel 6. A rack 8 is fixedly connected inside the right U-shaped installation groove 1. 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 installation groove 1. Glass curtain walls are installed inside both the first curtain wall panel 6 and the second curtain wall panel 7. The glass curtain walls are all arranged on the water-facing side and their positions do not interfere with the normal rotation of the sunshade strips 704. When performing small-flow heat exchange, it can be achieved only by relatively sliding the first sunshade panel 603 and the second sunshade panel 604 in the first curtain wall panel 6.

[0026] Specifically, the splicing component 5 includes a connection block 501 and two sealing grooves 504. The connection block 501 is fixedly connected to the middle of the outer side of the U-shaped installation groove 1. The two sealing grooves 504 are respectively fixedly connected to the front and rear sides of the U-shaped installation groove 1. The two sealing grooves 504 are respectively arranged on the front and rear sides of the connection block 501. Both front and rear ends of the side of the connection block 501 away from the U-shaped installation groove 1 are fixedly connected with first buckling blocks 502. A circular buckling groove 503 is penetrated and opened in the middle of the side of the first buckling block 502 away from the U-shaped installation groove 1. The connection block 501 is fixed to the middle of the outer side of the U-shaped installation groove 1, providing a core connection point for splicing. The design of the first buckling block 502 and the buckling groove 503 enables the adjacent curtain wall structures to be tightly connected by buckling when splicing the curtain wall structure horizontally. The connection is firm and reliable, and can effectively resist the action of external wind force, earthquake and other loads, ensuring the safety of the overall curtain wall structure.

[0027] Specifically, the splicing component 5 further includes a plug-in piece 505. Sealing pieces 506 are fixedly connected to the ends of both the front and rear sides of the plug-in piece 505. The sealing pieces 506 are inserted into the sealing grooves 504. On the inner sides of the sealing pieces 506 on both the front and rear sides of the plug-in piece 505, two groups of second buckling blocks 507 are fixedly connected. As a key component for connecting adjacent curtain wall structures, the plug-in piece 505 further enhances the stability of the horizontal splicing through the buckling cooperation of the second buckling blocks 507 with the buckling protrusions 508 and the first buckling blocks 502. This buckling method is simple to operate and convenient to install, enabling the rapid completion of the horizontal expansion of the curtain wall structure, improving the construction efficiency. The connection method between the connection block 501 and the plug-in piece 505 is "connection block 501 - plug-in piece 505 - connection block 501", that is, a plug-in piece 505 is arranged between two connection blocks 501. What is shown in the figure is actually the connection method between the plug-in piece 505 and the connection block 501, not the specific installation method.

[0028] Specifically, buckling protrusions 508 are arranged on the sides of the four groups of second buckling blocks 507 away from the plug-in piece 505. The buckling protrusions 508 are adapted to the first buckling blocks 502, and the first buckling blocks 502 are buckled between the buckling protrusions 508 and the plug-in piece 505. Plug-in columns 509 are fixedly connected to both sides of the middle part of the plug-in piece 505. The plug-in columns 509 are inserted into the buckling grooves 503. The insertion of the plug-in columns 509 into the buckling grooves 503 provides an additional positioning and fixing function for the splicing structure, ensuring that the positions of adjacent curtain wall structures are accurate after splicing and will not shift or shake, further improving the overall stability and sealing performance of the curtain wall structure.

[0029] Specifically, the first curtain wall panel 6 includes a fixed frame 601. The fixed frame 601 is fixedly connected to the middle position between two groups of U-shaped installation grooves 1 by bolts. Two groups of limiting grooves 605 are opened on both the front and rear sides of the fixed frame 601. Sliding grooves 602 are opened at both the upper and lower ends inside the fixed frame 601. A first sunshade panel 603 and a second sunshade panel 604 are slidably connected between the two groups of sliding grooves 602. The first sunshade panel 603 and the second sunshade panel 604 are distributed in a front-back staggered manner. The design of the sliding grooves 602 enables the first sunshade panel 603 and the second sunshade panel 604 to slide flexibly within the fixed frame 601. By adjusting their relative positions, the sunshade area and sunshade effect can be flexibly changed according to different sunlight irradiation angles and intensities, realizing the precise control of indoor light and improving the comfort of the indoor environment.

[0030] Rotating rods 606 are rotatably connected to both the left and right sides of the fixed frame 601. First synchronous pulleys 607 are fixedly connected to the outer surfaces of the two rotating rods 606. A first synchronous belt 608 is drivingly connected between the two first synchronous pulleys 607. Clamping plates 613 are fixedly connected to both the front and rear belts of the first synchronous belt 608. The two clamping plates 613 are respectively fixedly connected to the two second curtain wall panels 7. Through the transmission mechanism of the rotating rods 606, the first synchronous pulleys 607, and the first synchronous belt 608, the two second curtain wall panels 7 can be synchronously driven to move in opposite directions, realizing the folding linkage function of the curtain wall structure. This transmission method has a compact structure and stable transmission, can ensure the coordinated movement of the two second curtain wall panels 7, improves the operating stability and reliability of the curtain wall structure. The clamping plates 613 are fixedly connected to the second curtain wall panels 7, ensuring the effectiveness of the transmission and enabling the second curtain wall panels 7 to move accurately according to the design requirements.

[0031] Specifically, a micro motor 609 is fixedly connected to the right side of the bottom of the fixed frame 601. The end of the output shaft of the micro motor 609 is fixedly connected to a second synchronous pulley 610 through a coupling. A third synchronous pulley 611 is fixedly connected to the outer surface of the right lower rotating rod 606 on the left side of the first synchronous pulley 607. A second synchronous belt 612 is drivingly connected between the third synchronous pulley 611 and the second synchronous pulley 610. The micro motor 609 serves as the 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, realizing the automatic control of the movement of the second curtain wall panel 7. This automatic control method is convenient to operate and improves the usability of the curtain wall structure. At the same time, synchronous belt transmission has the advantages of accurate transmission ratio, stable operation, and low noise, which can ensure the stability and comfort of the curtain wall structure during operation.

[0032] Specifically, the second curtain wall panel 7 includes a moving frame 701. Two limiting blocks 702 are fixedly connected to the side of the moving frame 701 close to the first curtain wall panel 6. The two limiting blocks 702 are respectively slidably connected inside two groups of limiting grooves 605. The moving frame 701 is the main structure of the second curtain wall panel 7. The cooperation between the limiting blocks 702 and the limiting grooves 605 on the fixed frame 601 ensures that the moving frame 701 can stably move along the predetermined trajectory during movement, guaranteeing the operation accuracy and sealing performance of the curtain wall structure. This design enables the second curtain wall panel 7 not to shake or shift during movement, improving the overall performance of the curtain wall structure.

[0033] Specifically, several rotating shafts 703 are rotatably connected inside the moving frame 701. A sunshade strip 704 is fixedly connected to the outer side of the rotating shaft 703. The right end of the rotating shaft 703 penetrates through the right side wall of the moving frame 701 and is fixedly connected to a gear 705 that drives the rotating shaft 703 to rotate. The gear 705 meshes 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 offset from each other. Cooperating with the gear 705, the automatic adjustment of the angle of the sunshade strip 704 during the movement of the second curtain wall panel 7 is realized; The rack 8 includes two racks, which are respectively arranged at the upper end of the front side and the lower end of the rear side of the U-shaped installation groove 1; the rack at the upper end of the front side and the rack at the lower end of the rear side respectively form meshing with the gears 705 at the ends of the second curtain wall panel 7; the two racks are asymmetrically distributed along the U-shaped installation groove 1. When the second curtain wall panel 7 moves, the gear 705 rolls synchronously on the racks at the upper end of the front side and the lower end of the rear side; due to the spatial offset distribution of the two racks, the gear 705 generates differential rotation during the movement, and the transmission drives the rotating shaft 703 to drive the sunshade strip 704 to generate an angular deflection.

[0034] This design cleverly utilizes the movement of the second curtain wall panel 7 to realize the adjustment of the angle of the sunshade strip 704 without an additional driving device. The structure is simple and the cost is low. At the same time, it improves 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 realize the dynamic shielding of sunlight. This design of automatically adjusting the sunshade angle can provide the best sunshade effect according to different sunlight irradiation conditions, improve the comfort of the indoor environment, and reduce the indoor energy consumption at the same time.

[0035] When installing the telescopic folding linkage aluminum alloy curtain wall structure designed by the present invention, the following steps are carried out: S1. Horizontal splicing and expansion: Two groups of U-shaped installation grooves 1 are arranged in parallel at a predetermined position of the building main structure, and horizontal splicing is carried out; the sealing piece 506 of the insertion piece 505 is inserted into the sealing groove 504 of the adjacent unit U-shaped installation groove 1; the insertion column 509 of the insertion piece 505 is aligned and inserted into the buckling groove 503 of the connection block 501; the second buckling block 507 is pushed to make the buckling protrusion 508 form a mechanical buckle with the first buckling block 502; the positioning and locking of the insertion piece 505 and the connection block 501 are completed; S2. Vertical splicing and installation: Align the insertion block 3 of the upper U-shaped installation groove 1 with the insertion groove 4 of the lower unit; lower the upper unit along the gravity direction, and use the chamfer structure at the bottom of the insertion block 3 to realize guiding and positioning; after the insertion block 3 completely enters the insertion groove 4, a vertical direction load-bearing connection is formed; S3. Installation of the curtain wall panel system: The fixed frame 601 of the first curtain wall panel 6 is installed between two groups of U-shaped installation grooves 1 through fasteners; the limiting block 702 of the moving frame 701 is embedded in the limiting groove 605 of the fixed frame 601 to form a sliding fit; the clamping plate 613 is rigidly connected to the moving frame 701; S4. Start the micro-motor 609. The second synchronous pulley 610 drives the third synchronous pulley 611 through the second synchronous belt 612. The rotating rod 606 drives the first synchronous pulley 607 to rotate bidirectionally. The clamping plate 613 of the first synchronous belt 608 pulls the second curtain wall panel 7 to move reversely along the limit groove 605. The two groups of second curtain wall panels 7 form a symmetric displacement of unfolding / folding. S5. During the displacement of the second curtain wall panel 7, the gear 705 rotates along the meshing track of the rack 8. The rotating shaft 703 drives the sunshade strip 704 to form a continuous angular deflection. The first sunshade panel 603 and the second sunshade panel 604 form an interleaved displacement in the sliding groove 602. The deflection angle of the sunshade strip 704 and the displacement amount of the sunshade panel form a three-dimensional sunshade system.

[0036] Embodiment 1. This embodiment provides a specific method for the construction and installation of a retractable and foldable linkage aluminum alloy curtain wall structure: Install the two groups of U-shaped installation grooves 1 at the designated positions of the building. If it is necessary to expand multiple curtain wall structures horizontally, first place two curtain wall structures in parallel. Then insert the sealing piece 506 on the insertion piece 505 into the sealing groove 504 of the adjacent U-shaped installation groove 1, align the insertion post 509 on the insertion piece 505 and insert it into the buckling groove 503 in the connection block 501. At the same time, let the first buckling block 502 buckle between the buckling protrusion 508 of the second buckling block 507 and the insertion piece 505 to complete the splicing of multiple curtain wall structures horizontally. When carrying out the vertical assembly, only need to insert the insertion block 3 in another curtain wall structure into the insertion groove 4 in this curtain wall structure.

[0037] When a large amount of heat exchange is required to adjust the position of the second curtain wall panel 7, start the micro-motor 609. The output shaft of the micro-motor 609 drives the second synchronous pulley 610 to rotate. The second synchronous pulley 610 drives the third synchronous pulley 611 to rotate through the second synchronous belt 612. The third synchronous pulley 611 is fixed on the right lower rotating rod 606, thereby causing the rotating rod 606 to rotate. The first synchronous pulley 607 on the rotating rod 606 rotates accordingly. The two first synchronous pulleys 607 are driven by the first synchronous belt 608. The clamping plate 613 on the first synchronous belt 608 will drive the two second curtain wall panels 7 to move along the limit 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 by the two clamping plates 613 to move in opposite directions, that is, one second curtain wall panel 7 moves downward and the other second curtain wall panel 7 moves upward, and then reaches the same position as the first curtain wall panel 6, so that a large amount of heat exchange can occur between the room and the outside.

[0038] When closing, 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, during the sealing operation, when the second curtain wall panel 7 moves, the gear 705 will roll on the rack 8 as the second curtain wall panel 7 moves, thereby driving the rotation of the rotating shaft 703, and the sunshade strip 704 outside the rotating shaft 703 will rotate accordingly. In this way, the angle of the sunshade strip 704 can be automatically adjusted according to the sunlight irradiation angle and intensity to achieve the sunshade function. When it is necessary to adjust the sunshade effect of the first curtain wall panel 6, the first sunshade panel 603 and the second sunshade panel 604 are manually or driven by other devices to slide in the sliding groove 602. Since they are arranged offset from each other front and back, by adjusting their relative positions, the sunshade area and sunshade effect can be changed, and in cooperation with the sunshade strip 704 on the second curtain wall panel 7, a better sunshade function can be achieved.
