Description

Technical Field

[0001] This utility model relates to the field of glass curtain wall technology, and in particular to a corner connection structure for glass curtain walls. Background Technology

[0002] Glass curtain walls, as an important form of exterior building envelope in modern architecture, are widely used in high-rise buildings and large public buildings due to their transparency, aesthetic appeal, light weight, and superior lighting performance. A glass curtain wall typically consists of glass panels, a supporting structural system, and sealing materials. The supporting structural system generally uses a metal frame, forming a skeleton system through columns, beams, and other components to support and secure the glass panels. At the corners of a building, the curtain wall needs to adapt to changes in the building's shape, which places special requirements on the curtain wall's connection structure.

[0003] Existing glass curtain wall corner connection structures primarily employ adjustable-angle connection devices for corner installation. These structures typically include a rotating mechanism fixed to the keel column. This mechanism allows the glass panel and its supporting frame to rotate within a certain angle range, accommodating different corner angle requirements. During adjustment, the rotating mechanism drives the glass and its fixed frame to adjust the angle. After adjustment, a locking device secures the structure at the set angle. Compared to custom-designed fixed-angle keel components, this adjustable corner connection method offers better versatility and construction flexibility, adapting to the installation needs of different building corner angles.

[0004] However, existing adjustable corner connection structures have certain shortcomings in practical applications. Because the rotation adjustment mechanism requires sufficient adjustment space and strength, its structure is often quite prominent, forming a noticeable bulge on the outer side of the curtain wall. This not only affects the overall flatness of the curtain wall's appearance but also easily interferes with existing standard keel structures, resulting in poor installation compatibility. Furthermore, the protruding adjustment structure is difficult to effectively seal in the front area of ​​the curtain wall, affecting the sealing performance and aesthetic appearance of the corner area. These problems limit the widespread application of adjustable corner connection structures, necessitating the development of a corner connection structure that can achieve flexible angle adjustment, adapt well to existing keel structures, and maintain a flat and aesthetically pleasing curtain wall appearance.

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0031] Figure 1 This is a schematic diagram of the overall structure of an embodiment of the present invention; Figure 2 This is a schematic diagram of the cross-sectional structure of the adjustment component in an embodiment of the present invention; Figure 3 This is a schematic diagram of the column structure according to an embodiment of the present invention; Figure 4 This is a schematic diagram of the cross-sectional structure of the inclined pressure plate according to an embodiment of the present invention; Figure 5 This is a schematic diagram of the splicing panel structure according to an embodiment of the present invention; Figure 6 This is a schematic diagram of the adjustable protection component structure according to an embodiment of the present invention; Figure 7 This is a schematic diagram of the adjusting lever structure according to an embodiment of the present invention. Figures 1 to 7As shown, this utility model embodiment provides a glass curtain wall corner connection structure, including a column 100 and an adjustment component 001 disposed on one side of the column 100.

[0032] The adjustment component 001 includes a rotating arc 103 and a movable frame 300. The rotating arc 103 is provided in two sets. Rotating slide columns 201 are rotatably provided on the inner side of the rotating arc 103. A splicing frame 202 is installed on the side of each rotating slide column 201 away from the rotating arc 103. Several sets of splicing plates 400 are slidably spliced ​​on the outer side of the splicing frame 202. A flip bracket 401 is provided on the side of the splicing plate 400 farthest from the splicing frame 202. Two sets of meshing small gears 307 are rotatably provided inside the upper and lower ends of the movable frame 300. Large gears 306 are meshed on the outer side of the two sets of small gears 307. A limit shaft 303 is coaxially fixedly installed on the large gears 306. A rotating sleeve 304 is installed in the middle of the limit shaft 303. The outer side of the rotating sleeve 304 is connected to the flip bracket 401.

[0033] By adopting the above technical solution, this utility model achieves flexible adjustment and installation of the corner area of ​​the glass curtain wall by setting an adjustment component 001 on one side of the column 100. Specifically, the rotation arc 103 provides rotational support and angle limitation for the rotational sliding column 201, enabling the rotational sliding column 201 to be adjusted within a preset angle range, thereby adapting to different corner angle requirements. A splicing frame 202 is installed on the side of the rotational sliding column 201 away from the rotation arc 103. This splicing frame 202 is used to support and fix the insulated glass, providing a stable support structure for the curtain wall glass panel.

[0034] Several sets of splicing panels 400 are slidably spliced ​​on the outer side of the splicing frame 202. These splicing panels 400 can be flexibly selected and combined according to the actual shading area requirements to effectively close the front area of ​​the curtain wall corner. Through the sliding splicing design of the splicing panels 400, the splicing panels 400 can slide along the outer side of the splicing frame 202 during rotation and adjustment, thus always maintaining a close fit with the outer surface of the glass curtain wall. This avoids the problem of obvious bulges on the outer side of the curtain wall caused by the protruding rotation mechanism in traditional corner connection structures, effectively improving the overall flatness of the curtain wall appearance.

[0035] A flip bracket 401 is provided on the side of the splicing plate 400 furthest from the splicing frame 202, and this flip bracket 401 is connected to the movable frame 300. Two sets of meshing pinions 307 are rotatably installed inside the upper and lower ends of the movable frame 300, respectively. These two sets of pinions 307 achieve synchronous rotation through mutual meshing, ensuring the symmetry and synchronicity of the structures on both sides of the movable frame 300. A large gear 306 is meshed on the outer side of each set of pinions 307. The rotation angle is transmitted and controlled through the meshing of the pinions 307 and the large gears 306. A limit shaft 303 is coaxially fixedly installed on the large gear 306. A rotating sleeve 304 is installed in the middle of the limit shaft 303, and the outer side of the rotating sleeve 304 is connected to the flip bracket 401.

[0036] When the movable frame 300 moves relative to the column 100, the meshing transmission of the pinion 307 and the large gear 306 drives the limiting shaft 303 to rotate, which in turn drives the rotating sleeve 304 to rotate at the same angle. Because the two sets of pinions 307 mesh with each other, it ensures that the limiting shafts 303 and the rotating sleeve 304 on both sides always rotate synchronously at symmetrical angles, thus ensuring that the two sets of splicing frames 202 connected by the flip bracket 401 and the insulating glass they support are in a symmetrical state. This symmetrical synchronous rotation mechanism effectively avoids the problem of inconsistent angles of the glass panels on both sides of the corner area, improving installation accuracy and aesthetics.

[0037] More importantly, through the above structural design, the main body of the rotation adjustment mechanism is integrated inside the movable frame 300. The rotation adjustment function is achieved through the limiting shaft 303 and the rotating sleeve 304, avoiding the problem of the rotation mechanism protruding significantly in traditional solutions. The sliding splicing design of the splicing panel 400 ensures that it remains in contact with the outer surface of the curtain wall during rotation, effectively sealing the corner front area and improving sealing performance and aesthetics. At the same time, this structural design is well-suited for existing keel structures, especially columns. Installation can be achieved by connecting the movable frame 300 to the column 100, avoiding interference with the existing keel structure and improving installation adaptability and flexibility.

[0038] In summary, through the innovative design of the adjustment component 001, this utility model effectively solves the technical problems in the prior art, such as the prominent structure of the rotation adjustment mechanism, interference with the keel structure, and difficulty in sealing the front area, while achieving flexible adjustment of the corner angle. It improves the installation adaptability of the glass curtain wall corner connection structure and enhances the sealing performance and overall appearance of the corner area.

[0039] In one optional embodiment of this utility model, such as Figure 4 As shown, the top and bottom of the splicing frame 202 are spliced ​​with horizontally placed inclined pressure plates 204, and the side of the inclined pressure plate 204 away from the splicing frame 202 is provided with an inclined surface.

[0040] By employing the above technical solution, horizontally placed inclined pressure plates 204 are spliced ​​at the top and bottom of the splicing frame 202, facilitating the installation of the curtain wall glass and the horizontal keel structure. The inclined pressure plate 204 has an inclined surface on the side away from the splicing frame 202, which can smoothly insert into the inner side of the horizontal keel during the installation and rotation of the glass curtain wall. As the inclined pressure plate 204 gradually embeds into the horizontal keel, the inner wall of the keel exerts a squeezing force on the inclined surface. This squeezing force is transmitted to the splicing frame 202 through the inclined pressure plate 204, causing the splicing frame 202 to move closer to the center of the insulated glass, thereby enhancing the clamping and fixing effect of the splicing frame 202 on the insulated glass and improving the stability and sealing of the installation.

[0041] In one optional embodiment of this utility model, inclined inserts 203 are fixedly installed on the top and bottom of the splicing frame 202, inclined slots 205 are installed at the bottom of both ends of the inclined pressure plate 204, and the inclined slots 205 are spliced ​​on the outside of the inclined inserts 203. Two sets of hollow glass 207 are inserted into the inner side of the splicing frame 202, and a sealing ring 208 is provided between the two sets of hollow glass 207.

[0042] Using the above technical solution, the inclined insert 203 is fixedly installed on the top and bottom of the splicing frame 202, and inclined slots 205 matching the inclined insert 203 are installed at the bottom of both ends of the inclined pressure plate 204. The inclined slots 205 are spliced ​​on the outside of the inclined insert 203, forming an insert connection structure between the inclined pressure plate 204 and the splicing frame 202. This insert connection method not only facilitates the installation and disassembly of the inclined pressure plate 204, but more importantly, when the inclined pressure plate 204 is subjected to external compressive force, the compressive force is transmitted to the splicing frame 202 through the cooperation of the inclined slots 205 and the inclined insert 203.

[0043] Due to the inclined engagement structure of the inclined insert 203 and the inclined slot 205, when the inclined pressure plate 204 is subjected to downward pressure, the inclined slot 205 slides downward along the inclined surface of the inclined insert 203. This sliding process generates an inward component force, pushing the splicing frame 202 towards the center of the insulating glass 207, thus making the splicing frame 202 clamp the two sets of insulating glass 207 more tightly. Two sets of insulating glass 207 are inserted into the inner side of the splicing frame 202, forming two adjacent panels in the corner area of ​​the glass curtain wall. A sealing ring 208 is provided between the two sets of insulating glass 207. This sealing ring 208 not only serves a sealing function to prevent rainwater and airflow penetration, but also acts as a buffer and protector when the splicing frame 202 applies clamping force to the insulating glass 207, avoiding stress concentration and breakage caused by direct contact between the glass edges.

[0044] In one optional embodiment of this utility model, a sealing strip 206 is installed on the side of the inclined pressure plate 204 near the insulating glass 207, and the sealing strip 206 is spliced ​​and embedded in the inner side of the two sets of insulating glass 207.

[0045] Using the above technical solution, the sealing strip 206 is installed on the side of the inclined pressure plate 204 near the insulating glass 207 and is spliced ​​and embedded inside the two sets of insulating glass 207. The sealing strip 206 fills the gap between the inclined pressure plate 204 and the insulating glass 207, further improving the sealing performance of the corner area. When the inclined pressure plate 204 is compressed and moves inward, the sealing strip 206 simultaneously embeds into the inside of the insulating glass 207, providing double sealing protection on top of the sealing ring 208. This effectively prevents rainwater, dust, and airflow from seeping into the corner area, improving the overall sealing performance and service life of the curtain wall.

[0046] In one optional embodiment of this utility model, such as Figure 2 As shown, several sets of limiting sleeves 302 are fixedly installed on both sides of the movable frame 300, and the limiting shaft 303 is rotatably set inside the limiting sleeve 302. Horizontally arranged limiting guide rods 301 are fixedly installed on the upper and lower ends of the movable frame 300 near the column 100, and a fastening screw 305 is embedded in the middle of the movable frame 300.

[0047] Using the above technical solution, the limiting sleeve 302 is fixedly installed on both sides of the movable frame 300, providing rotational support and constraint for the limiting shaft 303. The limiting shaft 303 is rotatably positioned inside the limiting sleeve 302. The limiting sleeve 302 restricts the axial movement of the limiting shaft 303 while allowing it to rotate freely around its axis, ensuring that the rotating sleeve 304 can stably and reliably achieve the angle adjustment function. Horizontally arranged limiting guide rods 301 are fixedly installed on the upper and lower ends of the movable frame 300 near the column 100. These limiting guide rods 301 restrict the movement direction of the movable frame 300, ensuring that the movable frame 300 can only slide and adjust along a predetermined direction, i.e., perpendicular to the surface of the column 100. This prevents the movable frame 300 from deflecting or tilting during adjustment, ensuring the accuracy and stability of the adjustment.

[0048] A fastening screw 305 is embedded in the middle of the movable frame 300. This fastening screw 305 is used to fix and lock the movable frame 300 to the column 100 after the angle adjustment is completed. By tightening the fastening screw 305, a reliable fixed connection is formed between the movable frame 300 and the column 100, preventing changes in angle due to external forces during use, and ensuring the stability and reliability of the glass curtain wall corner connection structure.

[0049] In one optional embodiment of this utility model, such as Figure 3As shown, the front of the column 100 is provided with two sets of limiting holes 101, the limiting guide rod 301 is slidably disposed inside the limiting holes 101, the front of the column 100 is provided with two sets of limiting arcs 102, the rotating arc 103 is disposed inside the limiting arc 102, and several sets of arc-shaped limiting blocks 104 are installed outside the rotating arc 103, and the arc-shaped limiting blocks 104 are movably embedded inside the limiting arc 102.

[0050] Using the above technical solution, two sets of limiting holes 101 are provided on the front of the column 100, and the limiting guide rod 301 is slidably disposed inside the limiting holes 101. This structural design realizes the sliding guide connection between the movable frame 300 and the column 100. The limiting holes 101 provide precise guidance and constraint for the limiting guide rod 301, ensuring that the movable frame 300 can be smoothly slidably adjusted along the predetermined trajectory, while preventing the movable frame 300 from shifting laterally or rotating during the adjustment process, thus ensuring the accuracy of the adjustment.

[0051] Two sets of limiting arcs 102 are installed on the front of the column 100, and a rotating arc 103 is located inside the limiting arcs 102, forming a rotation guide mechanism for the rotating arc 103. Several sets of arc-shaped limiting blocks 104 are installed on the outer side of the rotating arc 103, and these arc-shaped limiting blocks 104 are movably embedded inside the limiting arcs 102. Through the cooperation between the arc-shaped limiting blocks 104 and the limiting arcs 102, the rotating arc 103 can rotate along an arc trajectory inside the limiting arcs 102. This structure not only provides stable rotational support for the rotating arc 103, but also limits the rotation angle range of the rotating arc 103, preventing the rotating slide column 201 from rotating excessively and affecting installation. At the same time, when it is necessary to fine-tune the rotation angle, precise angle adjustment can be achieved by adjusting the position of the rotating arc 103 within the limiting arcs 102, improving the flexibility and accuracy of installation.

[0052] In one optional embodiment of this utility model, such as Figure 5 As shown, several sets of stabilizing inserts 405 are installed on the side of the splicing plate 400 near the flip bracket 401. The side of the splicing plate 400 away from the flip bracket 401 is provided with a socket that matches the stabilizing insert 405. Adjacent sets of splicing plates 400 are connected by inserting the stabilizing insert 405 and the socket.

[0053] By adopting the above technical solution, several sets of stabilizing inserts 405 are installed on the side of the splicing panel 400 near the flip bracket 401, and matching sockets for the stabilizing inserts 405 are provided on the side of the splicing panel 400 away from the flip bracket 401, thus achieving plug-in connection between adjacent splicing panels 400. When it is necessary to increase the shielding area, the stabilizing insert 405 on one splicing panel 400 can be inserted into the socket of an adjacent splicing panel 400, thereby achieving cascading connection of multiple splicing panels 400. This plug-in connection method is not only convenient for installation and disassembly, but also allows for flexible adjustment of the number and combination of splicing panels 400 according to actual needs, adapting to different corner angles and shielding area requirements. The cooperation between the stabilizing insert 405 and the socket also provides sufficient connection strength and stability, ensuring that multiple splicing panels 400 form an integral structure after combination, preventing loosening or detachment during use.

[0054] In one optional embodiment of this utility model, a number of sets of limiting slide rails 200 are installed on the side of the splicing frame 202 away from the rotating slide column 201. On the outer side of the limiting slide rails 200, a number of sets of locking bolts 404 are passed through the splicing plate 400 away from the splicing slot 402. The locking bolts 404 are embedded in the inner side of another set of splicing plates 400 and the flip bracket 401. The splicing plate 400 is also provided with an assembly groove 403 that matches the limiting slide rail 200.

[0055] Using the above technical solution, several sets of limiting slide rails 200 are installed on the side of the splicing frame 202 away from the rotating slide column 201. These limiting slide rails 200 provide guide tracks for the sliding of the splicing plate 400 and the flipping bracket 401. An assembly groove 403 matching the limiting slide rail 200 is provided through the splicing plate 400. The assembly groove 403 slidably engages with the outside of the limiting slide rail 200, forming a sliding connection mechanism between the splicing plate 400 and the splicing frame 202.

[0056] Several sets of locking bolts 404 penetrate the side of the splicing panel 400 away from the splicing slot 402. These locking bolts 404 are embedded inside another set of splicing panels 400 and the flip bracket 401. By tightening the locking bolts 404, adjacent splicing panels 400 or splicing panels 400 and flip brackets 401 can be tightly locked together, enhancing the stability and rigidity of the overall structure. After angle adjustment and position adjustment are completed, the locking bolts 404 are used to fix and lock each splicing panel 400 and the flip bracket 401, preventing the splicing panels 400 from loosening or shifting due to vibration or external force during use, thus ensuring the long-term stability and reliability of the glass curtain wall corner connection structure.

[0057] In one optional embodiment of this utility model, such as Figure 1 and Figure 6As shown, an adjustment and protection assembly 002 is spliced ​​between the two sets of flipping brackets 401; the adjustment and protection assembly 002 includes an adjustment rod 506, and a reverse screw 507 is fixedly installed in the middle of the adjustment rod 506. Adjustment brackets 505 are movably arranged at both ends of the reverse screw 507, and two sets of drive rods 504 are rotatably arranged on the side of the adjustment bracket 505 away from the adjustment rod 506. The end of the drive rod 504 away from the adjustment bracket 505 is movably connected to the flipping bracket 401.

[0058] By employing the above technical solution, an adjustable protective assembly 002 is spliced ​​between two sets of flipping brackets 401, achieving the function of sealing and protecting the space inside the corner area. A reverse screw 507 is fixedly installed in the middle of the adjusting rod 506. The two threaded sections of the reverse screw 507 have opposite helical directions. Adjusting brackets 505 are movably installed at both ends of the reverse screw 507. The adjusting brackets 505 cooperate with the reverse screw 507 through a threaded connection.

[0059] When the user grasps and rotates the adjusting lever 506, the reverse lead screw 507 rotates synchronously. Since the threads at both ends of the reverse lead screw 507 are in opposite directions, the adjusting brackets 505 at both ends will simultaneously expand outwards or retract inwards during rotation, achieving symmetrical synchronous adjustment. Two sets of drive rods 504 are rotatably mounted on the side of the adjusting bracket 505 away from the adjusting lever 506. The end of the drive rod 504 away from the adjusting bracket 505 is movably connected to the flipping bracket 401.

[0060] When the two adjusting brackets 505 unfold towards both ends of the adjusting rod, the drive rod 504 drives the connected structural components, such as the stabilizing limit plate 500, to unfold outward, allowing the structural components to be spliced ​​and locked with the flipping bracket 401, thereby sealing and protecting the inner space of the corner area. This symmetrical unfolding mechanism, achieved through the adjusting rod 506 and the reverse lead screw 507, is easy to operate, precise in adjustment, and can flexibly adjust the protection range according to the actual installation situation, improving the sealing and aesthetics of the corner area.

[0061] In one optional embodiment of this utility model, such as Figure 5 , Figure 6 , Figure 7As shown, it also includes a stabilizing limit plate 500. A rotating bracket 502 is provided on one side of the stabilizing limit plate 500. The two ends of the drive rod 504 are rotatably connected to the adjusting bracket 505 and the rotating bracket 502 respectively through the rotating sleeve 503. A splicing insert plate 501 is provided on one side of the stabilizing limit plate 500. A splicing slot 402 is provided on the side of the flip bracket 401 away from the splicing plate 400. The splicing insert plate 501 is embedded in the inner side of the splicing slot 402. A connecting plate 508 is installed on the other side of the stabilizing limit plate 500. An elastic guard 509 is installed between the two sets of connecting plates 508.

[0062] Using the above technical solution, a rotating bracket 502 is provided on one side of the stabilizing limit plate 500, and the two ends of the drive rod 504 are rotatably connected to the adjusting bracket 505 and the rotating bracket 502 respectively through rotating sleeves 503. The rotating sleeve 503 enables the drive rod 504 to rotate relative to the adjusting bracket 505 and the rotating bracket 502, forming a hinged linkage transmission mechanism.

[0063] When the adjusting bracket 505 moves outward under the drive of the reverse lead screw 507, the drive rod 504 is hinged to the adjusting bracket 505 and the rotating bracket 502 through the rotating sleeve 503, converting the linear motion of the adjusting bracket 505 into the swing motion of the rotating bracket 502, thereby pushing the stabilizing limit plate 500 to unfold outward. A splicing insert plate 501 is provided on one side of the stabilizing limit plate 500, and a splicing slot 402 matching the splicing insert plate 501 is provided on the side of the flip bracket 401 away from the splicing plate 400.

[0064] When the stabilizing limiting plate 500 unfolds into position, the splicing insert 501 is embedded inside the splicing slot 402, forming a locking connection between the stabilizing limiting plate 500 and the flip bracket 401. It is important to note that both the splicing slot 402 and the splicing insert 501 have protruding structures. This design prevents the splicing insert 501 from sliding vertically after being inserted into the splicing slot 402; it can only be separated by reversing the operation. This ensures a reliable locking effect and prevents the stabilizing limiting plate 500 from falling off due to vibration or external force during use.

[0065] A connecting plate 508 is installed on the other side of the stabilizing limiting plate 500, and an elastic guard 509 is installed between the two sets of connecting plates 508. The elastic guard 509 is made of flexible or elastic material and has deformable characteristics. When the two sets of stabilizing limiting plates 500 are simultaneously unfolded outward and locked with the flip bracket 401, the distance between the two sets of connecting plates 508 increases. During this process, the elastic guard 509 is stretched and unfolded, sealing and protecting the inner space of the corner area. The elastic guard 509 can adapt to different corner angles and size changes, and in the unfolded state, it effectively prevents dust, rainwater, and airflow from seeping in from the inside of the corner, improving the sealing performance and overall aesthetics of the corner area.
