Description

Technical Field

[0001] This invention relates to the field of curtain wall installation technology, specifically to a quick positioning and installation connection mechanism for curtain wall panels. Background Technology

[0002] Curtain walls, as the exterior cladding structure of a building, do not bear the main load-bearing function. Constructed from lightweight panels, they resemble a curtain suspended from the building's exterior, combining decorative and enclosing functions, and are widely used in modern high-rise and large-scale buildings. Curtain wall systems are connected to the main building structure through prefabricated panel units, not only enhancing the building's visual appeal but also achieving physical properties such as thermal insulation, heat insulation, and waterproofing. Therefore, scientific, reliable, and efficient curtain wall installation methods are of great significance for ensuring building quality and improving construction efficiency.

[0003] To improve curtain wall construction efficiency, various rapid positioning and installation structures have been developed in the current technology. The core of these structures is the pre-installation of positioning devices on the building structure and the installation of matching connecting components on the back of the curtain wall panels, thereby achieving rapid alignment and installation of the curtain wall units. Common methods include pre-embedding positioning pins in the building structure to cooperate with the sleeves of the curtain wall panels for positioning; setting slots on the main body for insertion and fixing with latches or blocks on the back of the curtain wall; and using positioning bolts to connect and fix the curtain wall components to the structure. All these methods aim to reduce on-site adjustments and manual intervention, improving installation accuracy and operational efficiency.

[0004] However, in practical applications, this type of rapid positioning and installation structure for curtain walls usually still relies on the installation of a front frame, which needs to be fixed to the wall or beam frame with a large number of bolts. Then, the curtain wall panels are connected to the frame with multiple sets of bolts. The entire installation process requires repeated tightening of bolts, which is cumbersome and particularly inconvenient in space-constrained areas. In addition, when maintaining or replacing the curtain wall panels, a large number of bolts still need to be removed, which not only increases the difficulty of maintenance but also affects the overall efficiency of maintenance work. Therefore, this invention proposes a rapid positioning and installation connection mechanism for curtain wall panels to solve the above problems. Summary of the Invention

[0005] The purpose of this invention is to provide a quick positioning and installation connection mechanism for curtain wall panels to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a quick positioning and installation connection mechanism for curtain wall panels, comprising: a main beam frame, a set of connecting blocks symmetrically arranged on one side of the main beam frame, the set of connecting blocks being located on the upper and lower sides of the main beam frame respectively, each connecting block having a limit block fixedly connected to both ends, and the corresponding limit blocks located on the upper and lower sides being fixedly connected by a limit plate;

[0007] Each of the limiting blocks is fixedly connected to a positioning plate on the side away from the limiting plate. A set of limiting rods is fixedly connected to the side of the positioning plate away from the main beam. A first limiting mechanism is provided on the main beam near the positioning plate. The first limiting mechanism includes a first adjusting component and a limiting pressure block. The first adjusting component is used to adjust the limiting pressure block to rotate between the set of limiting rods and press it toward the positioning plate to achieve the limiting of the positioning plate.

[0008] A curtain wall panel is slidably connected between the two sets of limiting plates. Limiting grooves are formed on both the upper and lower surfaces of the curtain wall panel. A second limiting mechanism is provided between the connecting block and the limiting block. The second limiting mechanism includes a second adjusting component and a limiting rod. The second adjusting component is used to adjust the limiting rod to slide into and insert into the limiting groove, thereby achieving the limiting and fixing of the curtain wall panel between the limiting plates.

[0009] Preferably, the main beam frame has a positioning groove on the side near the connecting block, and the side of the connecting block and the limiting block near the positioning groove are fixedly connected to one side of the positioning block, while the other side of the positioning block is slidably inserted into the positioning groove.

[0010] Preferably, the first adjustment component includes a pressure plate, with a pressure handle fixedly connected to one side of the pressure plate, and the other side of the pressure plate slidably installed in the main beam frame.

[0011] Preferably, the lower surface of the pressure plate near the main beam is fixedly connected to one end of the first T-shaped column, and the other end of the first T-shaped column is fixedly connected to the first limiting sleeve through the first spring. The first limiting sleeve is fixedly installed on the main beam.

[0012] Preferably, the lower surfaces of both ends of one side of the pressure plate are fixedly connected to the rack, one side of the rack is slidably connected to one side of the fixed plate through the cooperation of the slider and the slide rail, and the other side of the fixed plate is fixedly connected to the main beam frame.

[0013] Preferably, a set of support seats is fixedly installed on the side of the fixed plate away from the main beam frame. Both support seats are rotatably connected to the end of the limiting shaft. A gear is fixedly sleeved in the middle of the limiting shaft. Limiting pressure blocks are arranged on both sides of the gear and fixedly connected to the limiting shaft. The gear and the rack are meshed together.

[0014] Preferably, an adjustment groove is provided in the middle of the connecting block on the side away from the main beam frame, and an adjustment column is rotatably installed in the adjustment groove, with the adjustment column fixedly sleeved in the middle position of the rotating shaft.

[0015] Preferably, the two ends of the rotating shaft pass through the connecting block and the limiting block in sequence and are rotatably connected to the connecting block and the limiting block.

[0016] Preferably, a second limiting sleeve is fixedly connected inside the adjusting groove. The inside of the second limiting sleeve is fixedly connected to one end of the second spring. The other end of the second spring is fixedly connected to one end of the second T-shaped column. The other end of the second T-shaped column is fixedly connected to one side of the U-shaped frame. An arc-shaped abutment is fixedly connected to the other side of the U-shaped frame. The arc-shaped abutment abuts against the outer ring surface of the rotating shaft through an anti-slip rubber sheet fixedly connected thereon.

[0017] Preferably, a fixed frame is fixedly installed inside the limiting block, and a rotating plate is provided on one side of the fixed frame.

The other end of the limiting rod is slidably installed in the guide block fixedly installed inside the fixed frame.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] 1. By employing a rapid positioning structure between the installation frame and the main beam, and an interlocking and limiting method between the curtain wall panels and the installation frame, the reliance on a large number of bolts in traditional installation processes is effectively reduced. During installation, a reliable connection between the main beam, installation frame, and curtain wall panels can be achieved simply through tightening and interlocking operations, significantly improving installation efficiency and reducing operational complexity, making it particularly suitable for construction environments with limited space.

[0020] 2. This mechanism facilitates rapid installation while also enabling subsequent disassembly and maintenance. By operating the corresponding adjustment components, the limiting relationships between various parts can be easily released, allowing for the rapid removal of curtain wall panels or the entire frame. This avoids the tedious process of disassembling a large number of bolts required in traditional structures, thereby improving the efficiency of maintenance work and reducing the cost of later replacement and repair.

[0029] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see Figures 1 to 6This invention provides a technical solution: a rapid positioning and installation connection mechanism for curtain wall panels, comprising: a main beam frame 1, which serves as the supporting body of the entire device and supports the curtain wall; a set of connecting blocks 2 symmetrically arranged on one side of the main beam frame 1, the connecting blocks 2 being located on the upper and lower sides of the main beam frame 1 respectively; each connecting block 2 having a limiting block 3 fixedly connected to both ends; the corresponding limiting blocks 3 on the upper and lower sides being fixedly connected by limiting plates 4; the fixed connection between the connecting blocks 2, the limiting blocks 3, and the limiting plates 4 forms an installation frame, thereby facilitating the installation of the curtain wall panels 8; each limiting block 3 having a positioning plate 5 fixedly connected to the side away from the limiting plate 4; and a set of limiting rods 6 fixedly connected to the side of the positioning plate 5 away from the main beam frame 1; the limiting rods 6 being perpendicular to the positioning plate 5. The main beam frame 1 is arranged in a straight line, and a first limiting mechanism is provided near the positioning plate 5. The first limiting mechanism includes a first adjusting component and a limiting pressure block 7. The first adjusting component is used to adjust the limiting pressure block 7 to rotate between a set of limiting rods 6 and press it towards the positioning plate 5 to limit the positioning plate 5. A curtain wall panel 8 is slidably connected between the two sets of limiting plates 4. The limiting plates 4 limit the curtain wall panel 8 to facilitate its sliding installation. Limiting grooves 9 are opened at the ends of the upper and lower surfaces of the curtain wall panel 8. A second limiting mechanism is provided between the connecting block 2 and the limiting block 3. The second limiting mechanism includes a second adjusting component and a limiting insertion rod 10. The second adjusting component is used to adjust the limiting insertion rod 10 to slide into the limiting groove 9 and insert it to achieve the limiting and fixing of the curtain wall panel 8 between the limiting plates 4.

[0031] In use, the main beam frame 1 is fixedly connected to the wall with bolts or other fasteners. When it is necessary to position and fix the installation frame composed of connecting block 2, limiting block 3, and limiting plate 4 to the main beam frame 1, the limiting block 3 is placed on one side of the main beam frame 1, so that the two limiting rods 6 on the positioning plate 5 are respectively on one side of the two limiting pressure blocks 7. At this time, by adjusting the first adjustment component, the limiting pressure block 7 is rotated towards the positioning plate 5 and presses the positioning plate 5, thereby limiting and fixing the positioning plate 5, thus limiting the limiting block 3 to one side of the main beam frame 1. Then, the connecting block 2 and the limiting plate 4 are limited and installed on the main beam frame 1. By limiting and fixing the four positioning plates 5, the installation frame composed of connecting block 2, limiting block 3, and limiting plate 4 is initially limited and fixed on the main beam frame 1. In addition, the limiting rods 6 and the limiting pressure blocks 7 abut against each other to limit the positioning, thereby preventing the lateral movement of the positioning plate 5 and further ensuring the limitation of the installation frame. With its fixed stability, when connecting the curtain wall panel 8 to the mounting frame, the curtain wall panel 8 is slidably inserted between the symmetrically arranged connecting blocks 2 by the limiting plate 4, so that the two sides of the curtain wall panel 8 are flush with the limiting plate 4, initially limiting the curtain wall panel 8. At this time, the limiting groove 9 opened on the curtain wall panel 8 corresponds to the position of the limiting rod 10. Then, by adjusting the second adjustment component, the limiting rod 10 slides into the limiting groove 9 and inserts until it abuts against the inside of the limiting groove 9, thereby further limiting and fixing the curtain wall panel 8 within the limiting plate 4, thus positioning and installing the curtain wall panel 8 within the mounting frame, ultimately achieving rapid positioning and installation between the main beam frame 1, the mounting frame, and the curtain wall panel 8. When subsequent disassembly is required, the limiting between the main beam frame 1, the mounting frame, and the curtain wall panel 8 can be quickly released by operating the first and second adjustment components. The operation is convenient, and the positioning and installation are accurate and reliable.

[0032] The main beam frame 1 has a positioning groove 11 on the side near the connecting block 2. The side of the connecting block 2 and the limiting block 3 near the positioning groove 11 are fixedly connected to one side of the positioning block 12. The other side of the positioning block 12 is slidably inserted into the positioning groove 11. Through the sliding insertion between the positioning block 12 and the positioning groove 11, the ease of positioning and installation of the installation frame formed by the connecting block 2, the limiting block 3 and the limiting plate 4 and the main beam frame 1 is improved. At the same time, the installation frame and the main beam frame 1 can be quickly connected.

[0033] The first adjustment component includes a pressure plate 14. A pressure handle 15 is fixedly connected to one side of the pressure plate 14. The pressure handle 15 facilitates the synchronous movement of the pressure plate 14 by pulling the pressure handle 15. The other side of the pressure plate 14 is slidably installed in the main beam frame 1, and the main beam frame 1 limits the position of the pressure plate 14. At the same time, guide holes are opened at both ends of the pressure plate 14, and the guide holes are slidably fitted into guide rods fixedly installed on the main beam frame 1, further improving the stability of the pressure plate 14 during movement. The lower surface of the pressure plate 14 near the main beam frame 1 is fixedly connected to one end of the first T-shaped column 16. The other end of the first T-shaped column 16 is fixedly connected to the first limiting sleeve 18 through a first spring 17. The first spring 17 is an industrial-grade spring with good fatigue resistance, can be repeatedly stretched for long-term use, and can be further adjusted after long-term use. The first limiting sleeve 18 is fixedly installed in the main beam frame 1, and the first T-shaped column 16 is slidably installed in the first limiting sleeve 18. The lower surfaces of both ends of one side of the pressure plate 14 are fixedly connected to the rack 19. One side of the rack 19 is slidably connected to one side of the fixed plate 20 through the cooperation of the slider and the slide rail. The slider is fixedly connected to the rack 19, and the slide rail is fixedly installed on the fixed plate 20. The other side of the fixed plate 20 is fixedly connected to the main beam frame 1. A set of support seats 21 is fixedly installed on the side of the fixed plate 20 away from the main beam frame 1. Both support seats 21 are rotatably connected to the end of the limiting shaft 22. The support seats 21 support and limit the limiting shaft 22. A gear 23 is fixedly sleeved in the middle of the limiting shaft 22. The limiting pressure block 7 is set on both sides of the gear 23 and fixedly connected to the limiting shaft 22. The gear 23 is meshed with the rack 19.

[0034] First, by pulling the pressure handle 15 towards the limit rod 6, the pressure handle 15 drives the pressure plate 14 to move synchronously. The pressure plate 14 moves under the sliding fit between the guide hole and the guide rod, causing the pressure plate 14 to drive the rack 19 fixedly connected at both ends to move. At the same time, the pressure plate 14 will press the first T-shaped post 16 to slide within the first limit sleeve 18, and compress the first spring 17. As the rack 19 moves, it will mesh with the gear 23. The gear 23 will then drive the limit shaft 22 fixedly sleeved inside to rotate. The limit shaft 22 will then drive the limit block 7 to rotate away from the fixed plate 20 until the limit block 7 and the fixed plate 20 are at a distance. In the parallel state, the initial sliding connection between the positioning groove 11 and the positioning block 12 initially positions the installation frame. At this time, the positioning plate 5 is directly below the fixing plate 20. Then, the pressure handle 15 is released, and under the reverse elastic force of several first springs 17, the pressure plate 14 moves in the direction, thereby driving the rack 19 to slide in the reverse direction. Again, through the meshing transmission between the rack 19 and the gear 23, the limiting shaft 22 drives the limiting pressure block 7 to rotate in the reverse direction until the limiting pressure block 7 is pressed against one side of the positioning plate 5, thereby limiting and fixing the positioning plate 5 on the main beam frame 1, and thus indirectly positioning and installing the installation frame on one side of the main beam frame 1.

[0035] An adjustment groove 24 is provided on the side of the connecting block 2 away from the main beam frame 1. An adjustment column 25 is rotatably installed in the adjustment groove 24. The adjustment column 25 is fixedly sleeved in the middle position of the rotating shaft 26, so that the rotating shaft 26 can be rotated synchronously by twisting the adjustment column 25. The two ends of the rotating shaft 26 pass through the connecting block 2 and the limiting block 3 in sequence and are rotatably connected to the connecting block 2 and the limiting block 3. The connecting block 2 and the limiting block 3 limit the rotation of the rotating shaft 26 to ensure the rotational stability of the rotating shaft 26. The adjustment groove 24 is fixedly connected to the first... The second limiting sleeve 27 is fixedly connected to one end of the second spring 28. The second spring 28 is an industrial-grade spring with excellent fatigue resistance, capable of repeated stretching for long-term use, and replaceable after prolonged use. The other end of the second spring 28 is fixedly connected to one end of the second T-shaped post 29, and the other end of the second T-shaped post 29 is fixedly connected to one side of the U-shaped frame 30. The second T-shaped post 29 is slidably fitted inside the second limiting sleeve 27. An arc-shaped abutment is fixedly connected to the other side of the U-shaped frame 30. Plate 31, an arc-shaped abutment plate 31, abuts against the outer surface of the rotating shaft 26 via an anti-slip rubber sheet 32 ​​fixedly connected thereto. The anti-slip rubber sheet 32 ​​is arc-shaped, and the contours of both the arc-shaped abutment plate 31 and the anti-slip rubber sheet 32 ​​are adapted to the outer surface of the rotating shaft 26. A fixing frame 33 is fixedly installed inside the limiting block 3, and a cavity for the fixing frame 33 is formed inside the limiting block 3. A rotating plate 34 is provided on one side inside the fixing frame 33. One end of the rotating plate 34 is fixedly sleeved on the rotating shaft 26, and the other end of the rotating plate 34 is connected to the first connecting plate 3 via a connecting pin. One end of the first connecting plate 35 is rotatably connected, and the other end of the first connecting plate 35 is rotatably connected to one end of the second connecting plate 36 and the third connecting plate 37 through a limiting pin. The other end of the second connecting plate 36 is rotatably connected to the fixed frame 33 through a fixing pin. The other end of the third connecting plate 37 is rotatably connected to one end of the limiting rod 10 through a transmission pin. The other end of the limiting rod 10 is slidably installed in the guide block 13 fixedly installed in the fixed frame 33. The guide block 13 limits the limiting rod 10, thereby ensuring its stability during movement.

[0036] After the installation frame is quickly positioned and installed, when the curtain wall panel 8 needs to be installed, it is slidably installed between the limiting plates 4 by limiting the panel 8, so that the side wall of the curtain wall panel 8 is flush with the end face of the limiting plate 4. This initially limits the curtain wall panel 8 to prevent it from falling and improves the safety factor. In order to further limit and fix the curtain wall panel 8, the U-shaped frame 30 is first pulled away from the adjusting column 25, so that the U-shaped frame 30 drives the second T-shaped column 29 to move. The second T-shaped column 29 presses the second spring 28 and slides in the second limiting sleeve 27, so that the U-shaped frame 30 drives the arc-shaped abutment plate 31 away from the rotating shaft 26. At this time, by twisting the adjusting column 25, the adjusting column 25 drives the rotating shaft 26 to rotate. The rotating shaft 26, under the limitation of the connecting block 2 and the limiting block 3, drives the rotating plate 34 to rotate. The rotating plate 34 drives the second connecting plate 36 and the third connecting plate 37 to move through the connecting pin. The second connecting plate 36 rotates closer to the rotating shaft 26 under the limitation of the fixing pin on the fixing frame 33. The third connecting plate 37, in cooperation with the connecting pin and the transmission pin, pushes the limiting rod 10 to move, so that the limiting rod 10 moves into the limiting groove 9 under the limitation and guidance of the guide block 13, until the limiting rod 10 completely abuts in the limiting groove 9. After the completion, the curtain wall panel 8 is quickly positioned and installed. Then the U-shaped frame 30 is released. Under the reverse elastic force of the second spring 28, the U-shaped frame 30 drives the anti-slip rubber sheet 32 ​​on the arc-shaped abutment plate 31 to abut tightly against the outer ring surface of the rotating shaft 26, so as to prevent the rotating shaft 26 from rotating at will, thereby ensuring the insertion stability of the limiting rod 10 and preventing it from rotating at will.
