Description

Technical Field

[0001] This invention belongs to the field of construction curtain walls, and more specifically, relates to a connection structure for irregularly shaped curtain walls suitable for inclined states. Background Technology

[0002] With the continuous development of modern building technology and the innovation of building structures, curtain walls, as an important form of building facade, have gradually become a hallmark feature of large-scale buildings. The emergence of curtain walls not only meets the needs of building facades for lighting, heat insulation, and energy conservation, but also endows buildings with a more modern and futuristic appearance, making them part of the urban landscape. Due to the accumulation of curtain wall projects year after year, ordinary-shaped curtain walls can no longer meet current aesthetic demands. Therefore, irregularly shaped curtain walls, with their non-traditional construction, through ingenious design and innovative technologies, endow buildings with unique appearance characteristics and artistry, and are gradually gaining favor in the construction industry.

[0003] Irregularly shaped curtain walls typically require customized design and fabrication based on specific building requirements. Their complex and varied structural forms necessitate specialized components and connection methods to meet unique aesthetic demands. A common method is to connect the building to the irregularly shaped curtain wall by pre-drilling holes in the curtain wall panel and inserting supporting structural members into these holes for fixation, creating an embedded connection. This embedded connection allows for a tighter fit, minimizing gaps between the curtain wall panel and the supporting structure, resulting in better sealing performance. However, this method requires more steps and time during installation and dismantling, and is less convenient for maintenance and panel replacement. Furthermore, while embedded connections are primarily suitable for metal curtain wall panels, they are less suitable for other materials such as stone or glass, depending on their specific properties and manufacturing processes.

[0004] For stone or glass curtain wall panels, suspended connections are typically used. This connection method offers structural flexibility, effectively isolating the building from direct contact with the curtain wall, reducing the risk of corrosion or oxidation, and extending the service life of the components. However, if the installed curtain wall is at an angle, bending and torsional effects may occur in the connection structure, leading to uneven stress distribution and potentially causing structural deformation or even damage to the curtain wall panels. Therefore, in modern irregular-shaped curtain wall design, improving the suspended connection structure to meet the installation requirements of curtain walls with different angles while ensuring the connection performance between the curtain wall panels and the building substrate, avoiding large displacements that could affect the safety of the curtain wall structure, and guaranteeing the rigidity of the curtain wall structure has become a current research and application hotspot.

[0005] Patent application CN115142594A discloses a connection structure for irregularly shaped glass curtain walls, comprising two glass panels, each with a vertical subframe fixedly connected to its top. Four fixing bolts are installed inside the facing horizontal beams of the vertical subframes. This structure uses pins to fix the columns to the covers, bolts to fix the connecting blocks to the covers, and four connecting bolt assemblies to fix the two horizontal beams to two rotatable connecting components, thereby connecting the panel system to the wall. This device facilitates multi-angle and hyperbolic gradient shapes in buildings, is suitable for super high-rise buildings, and is easy to assemble in factories. However, this connection structure is more suitable for transitional connections between two glass curtain walls, leaning more towards horizontal rotation with limited range. Vertical rotation is difficult to achieve. Furthermore, under wind loads and other forces, stress concentration may occur in the connecting components between the curtain walls, causing damage to the curtain wall connection structure and affecting the overall structural stability.

[0006] The invention patent with authorization announcement number CN111910803B discloses a complex irregular-shaped curtain wall structure, including an irregular-shaped curtain wall building base, decorative panels connected to the outside of the irregular-shaped curtain wall building base, and multiple connecting devices. One end of the connecting device is fixed to the main building structure, and the other end of the connecting device is movably connected to the irregular-shaped curtain wall building base. Although this structure can adapt to the construction requirements of unequal distances between the irregular-shaped curtain wall building base and the main building structure, and can ensure a smooth transition of the complex irregular-shaped curtain wall structure, thereby ensuring the engineering quality and overall effect of the complex irregular-shaped curtain wall structure, the following problems arise: the cost of the whole irregular-shaped aluminum panel is high, the intermediate loss is large, the installation efficiency is also very low, and this structure is difficult to achieve the tilted shape in the existing curtain wall exterior cladding. The multi-curvature changes and smoothness between the panels are difficult to solve, and the engineering quality and overall effect of complex-shaped buildings cannot be guaranteed.

[0007] Therefore, in order to improve the stability of the building curtain wall support structure, the adjustability of the curtain wall tilt angle, the integrity between the curtain wall and the building substrate, and the convenience of installation and subsequent disassembly and maintenance, there is an urgent need for a new curtain wall connection structure. Summary of the Invention

[0008] The purpose of this invention is to provide a connection structure for irregularly shaped curtain walls that is suitable for tilting angles. While reducing the difficulty of construction and installation, it can enhance the overall connection between curtain wall structures, improve the adaptability of curtain walls to different tilting angles, and facilitate installation and control.

[0009] To achieve the objective of this invention, the technical solution adopted is as follows: an irregular curtain wall connection structure suitable for tilting angles, including a rotating structure installed between the building substrate and the curtain wall panel that enables the curtain wall panel to rotate on the building substrate, and a fixing structure that satisfies the rotation of the curtain wall panel on the building substrate is also installed between the building substrate and the curtain wall panel; the fixing structure is multiple, and the multiple fixing structures are respectively located on both sides of the rotation center axis of the rotating structure.

[0010] Furthermore, the rotating structure includes a rotating component for fixing to the building substrate and a supporting component for fixing to the curtain wall panel, the supporting component being rotatable relative to the rotating component.

[0011] Furthermore, a connecting member is also sleeved on the support member, and the connecting member can rotate relative to the rotating member.

[0012] Furthermore, the rotating component includes two opposing sector plates, with a horizontal plate connecting the two sector plates, and grooves installed on both sector plates, with keel bolt holes opened on both the grooves and the horizontal plate.

[0013] Furthermore, the sector plate is also provided with slots for inserting the slotted parts, and the two slotted parts are inserted into the slots respectively and then plugged into each other.

[0014] Furthermore, one of the slots has a wedge-shaped insertion end, and the other slot has a matching wedge-shaped hole at its insertion end.

[0015] Furthermore, the connector is installed between the two sector plates by the first bolt, and both sector plates are provided with arc-shaped holes. The connector and the support are provided with rectangular holes corresponding to the arc-shaped holes, and rectangular blocks are inserted into both the arc-shaped holes and the rectangular holes.

[0016] Furthermore, the rectangular block has protrusions evenly distributed on the surface that mates with the arc-shaped hole wall.

[0017] Furthermore, the connector and the support are provided with corresponding concave holes, and a concave block is inserted into multiple concave holes. The arc surface of the fan-shaped plate is also provided with a groove track that matches the concave surface of the concave block.

[0018] Furthermore, the support member has a connecting arm and two supporting feet. The rectangular hole and the concave hole are both located on the connecting arm, and the connecting member is U-shaped with the connecting arm located inside the connecting member. The connecting arm is also provided with a second bolt that extends along its axial direction and passes through the rectangular block and the concave block, and a nut is tightened at the tail of the second bolt.

[0019] Furthermore, the support foot also has a connecting plate that connects to the curtain wall panel.

[0020] Furthermore, the fixing structure includes two channel steels that are respectively connected to the building base and the curtain wall panel. The channel steels have multiple elongated holes arranged at intervals along their axial direction, and locking bolts are installed in two corresponding elongated holes.

[0021] Furthermore, a flat steel is provided between the two channel steels, and the locking bolt passes through the flat steel during installation.

[0022] Furthermore, the outer end of the channel steel is fitted with an angle steel that connects to the curtain wall panel or the building substrate.

[0023] The beneficial effects of this invention are:

[0024] 1. This invention, by installing a rotating structure and a fixing structure between the curtain wall panel and the building substrate, not only can the curtain wall panel be securely installed on the building substrate, but also allows for adjustments to the curtain wall panel's tilt angle. First, the fixing structure's locking mechanism can be loosened, then the rotating structure can be adjusted to change the tilt angle, and finally, the fixing structure can be re-locked. This invention is applicable to installation requirements with different tilt angles of the curtain wall panel, allows for angle adjustments of the rotating and fixing structures within a certain range, and meets the construction requirements for smooth curtain wall panel connections. It reduces the impact on the overall building structure, avoids damage to the curtain wall panel due to accumulated errors, and thus improves the overall stability with the main structure while ensuring the curtain wall's tilt angle, providing a reference for engineering practice.

[0025] 2. Reliability and Stability: By engaging the protrusions on the rectangular blocks with the walls of the arc-shaped holes, and engaging the concave parts on the concave blocks with the grooves on the arc-shaped plates, the connectors can achieve a stable connection through frictional engagement at any angle, preventing them from pivoting arbitrarily. This structure is similar to a clamping device, improving the overall stability of the structure. At the same time, the multi-point support method using rectangular blocks, concave blocks, and the first bolt can effectively cope with various moments and oblique pressures under tilted conditions, distributing and transferring the overall load of the curtain wall panel to multiple support points, making the structure more robust and stable, and ensuring the safety of the curtain wall structure.

[0026] 3. Excellent adaptability: When angle adjustment is required, the connector can be rotated to any angle and then fixed by two interacting rectangular and concave blocks, thus adapting to the installation needs of curtain walls at different tilt angles. This connection structure can be flexibly adjusted and modified according to specific building forms and design requirements, improving the adaptability and design diversity of curtain wall panels.

[0027] 4. Reduced Installation Difficulty: Because this rotating and fixed structure uses fewer members, the rotating structure can be rotated without repeated disassembly and reassembly, simplifying the installation process and reducing requirements on the construction site. Since the support points in the rotating structure are relatively dispersed, installation is more flexible and convenient, reducing the need for special equipment and processes, and lowering construction difficulty.

[0028] 5. Saves material costs: Compared with traditional single-point support systems or other connection structures, the multi-point support of this connection structure is more rationally designed, which can reduce the amount of materials used, thereby reducing material costs and conforming to the concept of building energy conservation and environmental protection; at the same time, operators can assemble it more conveniently, thereby greatly improving work efficiency and saving overall costs to a certain extent.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present invention are shown in the accompanying drawings.

[0050] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0051] like Figure 1 , Figure 10As shown, this invention provides a connection structure for irregularly shaped curtain walls suitable for inclined states, including a rotating structure 3 and a fixed structure 7. Both the rotating structure 3 and the fixed structure 7 are installed between the curtain wall panel 8 and the building base 2. During installation, the building base 2 is preferably a keel frame, which is generally grid-shaped and includes horizontal and vertical keels. Both the horizontal and vertical keels are made of light steel keels, and both have inwardly widened grooves. The horizontal keels are connected to the vertical keels with bolts to form the keel frame. Specifically, the rotating structure 3 can be installed on the horizontal keel, and the fixed structure 7 can be installed on the vertical keel. Alternatively, the rotating structure 3 can be installed on the vertical keel, and the fixed structure 7 can be installed on the horizontal keel; or both the rotating structure 3 and the fixed structure 7 can be installed on the vertical keel. In actual installation, after the curtain wall panel 8 is installed on the rotating structure 3 and the fixed structure 7, the tilt angle of the curtain wall panel 8 can be adjusted by rotating the rotating structure 3. Since the tilt angle of the curtain wall panel 8 needs to be adjusted in terms of both tilt and length, the fixed structure 7 can be adjusted by bending or by a combination of extension and hinge to meet the tilt adjustment of the curtain wall panel 8.

[0052] In this invention, the fixing structures 7 are at least two or four. When the curtain wall panel 8 needs to be tilted, multiple fixing structures 7 are located at the upper and lower ends of the curtain wall panel 8, respectively. When the curtain wall panel 8 needs to be flipped left or right, multiple fixing structures 7 are located at the left and right ends of the curtain wall panel 8, respectively. This ensures that the tilt adjustment of the curtain wall panel 8 is achieved while making the installation of the curtain wall panel 8 more stable. In addition, when there are two fixing structures 7 located at the upper and lower ends or at the left and right ends of the curtain wall panel 8, the two connecting structures located at the same end of the curtain wall panel 8 can be installed on the same horizontal keel or the same vertical keel.

[0053] like Figure 2 As shown, the rotating structure 3 includes a rotating component 302, a connecting component 303, and a supporting component 304. The rotating component 302 is installed on the building base 2, the supporting component 304 is fixed to the curtain wall panel 8, and the connecting component 303 is sleeved on the supporting component 304. The end of the connecting component 303 near the rotating component 302 extends beyond the supporting component 304, so that the supporting component 304 and the rotating component 302 are connected by the connecting component 303. The swing of the connecting component 303 on the rotating component 302 can be adjusted, and after the connecting component 303 is adjusted, the connecting component 303 and the rotating component 302 can be linearly locked and fixed, thereby adjusting the tilt angle of the curtain wall panel 8.

[0054] like Figure 3As shown, the rotating component 302 includes two opposing sector plates 3021 with a certain distance between them, and a horizontal plate 3022 connecting the two sector plates 3021, making the rotating component 302 U-shaped. The lower surface of the horizontal plate 3022 is flush with the horizontal edge of the sector plate 3021, so that the rotating component 302 can be installed on the building base 2 and the horizontal plate 3022 can fit against the surface of the building base 2. At the same time, the horizontal plate 3022 is also provided with keel bolt holes 3011, so that when the rotating component 302 is installed, the keel bolts 3012 can pass through the keel bolt holes 3011 on the horizontal plate 3022 and be fixed in the building base 2, thereby achieving the initial fixation of the rotating component 302. Both of the aforementioned sector plates 3021 are equipped with grooves 301, which extend outward from the two sector plates 3021 respectively. Both grooves 301 also have bolt holes 3011. During installation, the rotating component 302 can be simultaneously fixed to the building base 2 using bolts 3012 passing through the bolt holes 3011 on the grooves 301, thus achieving secondary fixation of the rotating component 302. By additionally setting the grooves 301, the contact surface between the rotating component 302 and the building base 2 can be effectively increased, making the installation of the rotating component 302 more secure. In this invention, to make the installation of the rotating component 302 and the grooves 301 more stable, there can be multiple bolt holes 3011 on both the horizontal plate 3022 and the grooves 301, with these multiple bolt holes 3011 spaced apart along the length of the horizontal plate 3022.

[0055] The sector plate 3021 is also provided with a slot 3027, which is higher than the horizontal plate 3022 and is a rectangular hole 3031. The slot 301 is Z-shaped and fits the slot 3027 with a clearance. During installation, the inner end of the slot 301 extends through the slot 3027 to the space between the two sector plates 3021. The keel bolt 3012 fixes the outer end of the slot 301 to the building base 2, thereby achieving secondary fixation of the rotating component 302. By fitting the slot 3027 with the inner end of the slot 301, after the slot 301 is fixed to the building base 2, the inner end of the slot 301 can press and fix the rotating component 302. This eliminates the need for welding or bolts to connect the slot 301 to the rotating component 302, thus completing the pressing and fixing of the rotating component 302 and making the installation and disassembly of the rotating component 302 more convenient.

[0056] To improve the clamping effect of the slot 301 on the rotating part 302 and prevent the slot 301 from separating from the rotating part 302, the inner end of one slot 301 is rectangular, and the end face of the inner end of the slot 301 is provided with a slot hole 3027, which is a wedge-shaped hole 3013. The inner end of the other slot 301 is directly set as a wedge shape to cooperate with the wedge-shaped hole 3013. When installing the two slots 301, the two slots 301 are first passed through the rectangular holes 3031 on the two sector plates 3021 respectively. Then, the slot 301 with the wedge-shaped inner end is inserted into the slot 301 with the wedge-shaped hole 3013 at the inner end, thereby realizing the insertion between the two slots 301. When both slotted parts 301 are fixed with keel bolts 3012, the two slotted parts 301 are locked, which not only achieves the pressing and fixing of the rotating part 302, but also effectively prevents the rotating part 302 from separating from the slotted parts 301, making the installation of the rotating part 302 more stable; at the same time, since the pressing position of the slotted parts 301 on the rotating part 302 is higher than the fixing point of the rotating part 302 itself, the upper end of the rotating part 302 will not tilt to the left or right after being subjected to force, thereby avoiding the lateral shaking of the connecting part 303.

[0057] In this invention, while ensuring that the two slots 301 can be plugged into each other, the slot hole 3027 at the inner end of one slot 301 can be rectangular or cylindrical, and the inner end of the other slot can be rectangular or cylindrical. In this case, when installing the two slots 301, the inner end of one slot 301 can be inserted into the inner end of the other slot 301, which can realize the plugging between the two slots 301 and the pressing of the rotating part 302.

[0058] like Figure 2 , Figure 4 , Figure 6As shown, the connector 303 and the two sector plates 3021 are each provided with corresponding first bolt holes 3023. When the connector 303 is installed, the corresponding first bolt holes 3023 on the connector 303 and the two sector plates 3021 are all equipped with first bolts 4. The tail of the first bolt 4 is tightened with a nut 3046, so that the connector 303 and the rotating part 302 are connected by the first bolt 4. Both of the aforementioned sector plates 3021 are provided with arc-shaped holes 3025. The center of the arc-shaped hole 3025 is at the same point as the center of the arc edge of the sector plate 3021. The connector 303 and the support 304 are provided with corresponding rectangular holes 3031. During the adjustment process of the connector 303 swinging on the rotating member 302, the rectangular hole 3031 always corresponds to the arc-shaped hole 3025. When the connector 303 swings to a fixed position on the rotating member 302, a rectangular block 5 is inserted into both the rectangular hole 3031 and the arc-shaped hole 3025. At this time, the hole wall of the arc-shaped hole 3025 will restrict the rectangular block 5, so that the connector 303 cannot swing on the rotating member 302, thereby locking the adjusted connector 303. It should be noted that the end face of the rectangular block 5 is fan-shaped, and the center of the fan-shaped circle is on the same straight line as the center of the arc-shaped hole 3025, so that the rectangular block 5 can be inserted into the rectangular hole 3031 and cooperate with the wall of the arc-shaped hole 3025 no matter what angle the connector 303 swings to.

[0059] like Figure 2 , Figure 4 , Figure 6 As shown, in this invention, the arc-shaped hole 3025 is designed to ensure the rotation of the connecting rod on the rotating member 302. The first bolt hole 3023 on the rotating member 302, used for installing the first bolt 4, is located between the slot hole 3027 and the arc-shaped hole 3025. Simultaneously, to prevent slippage between the surface of the rectangular block 5 and the wall of the arc-shaped hole 3025, protrusions 501 are evenly distributed on the surface of the rectangular block 5 that mates with the wall of the arc-shaped hole 3025. This effectively increases the friction between the rectangular block 5 and the wall of the arc-shaped hole 3025 after the rectangular block 5 is inserted into both the arc-shaped hole 3025 and the rectangular hole 3031. This results in a better locking effect for the connecting member 303 after the rectangular block 5 is inserted into both the rectangular hole 3031 and the arc-shaped hole 3025. Compared to existing screw locking methods, the installation and disassembly of this invention are more convenient.

[0060] like Figure 4As shown, both the connector 303 and the support 304 have concave holes 3032. The end face of the concave hole 3032 is in the shape of a "U". The concave hole 3032 on the connector 303 corresponds to the concave hole 3032 on the support 304. A concave block 6 is inserted into both the concave hole 3032 on the connector 303 and the concave hole 3032 on the support 304. The end face of the concave block is also in the shape of a "U". The arc-shaped surface of the sector plate 3021 is provided with a grooved track 3026, which is serrated. When the concave block 6 is inserted into the corresponding concave hole 3032, the two stepped shoulders on the concave block 6 are engaged with the grooved track 3026. This allows the concave block 6 to lock the connector 303 and the support 304, and also to lock the concave block 6 and the rotating member 302 through the cooperation of the concave block 6 and the grooved track 3026. This further locks the connector 303 with the rotating member 302, making the swing of the connector 303 more stable after adjustment. To improve the engagement effect between the concave block and the grooved track 3026, the two stepped shoulders on the concave block 6 are adapted to the engagement grooves on the grooved track 3026.

[0061] like Figure 4 , Figure 5 As shown, the support member 304 has a connecting arm 3041 and two supporting feet 3042. That is, the support member 304 is Y-shaped to facilitate force transmission. The connecting arm 3041 is one end of the support member 304 sleeved inside the connector 303. The two supporting feet 3042 are used to jointly install the curtain wall panel 8. Therefore, the rectangular hole 3031 and the concave hole 3032 are both located on the connecting arm 3041. The connector 303 is U-shaped. The inner wall of the connector 303 is clearance-fitted with the outer wall of the connecting arm 3041. In order to avoid interference between the connector 303 and the inner wall of the arc plate when the connector 303 swings on the rotating member 302, the width of the connector 303 is adapted to the distance between the two arc plates. The connecting arm 3041 is also provided with an axially penetrating second bolt hole 3044, that is, the axial direction of the second bolt hole 3044 is consistent with the axial direction of the connecting arm 3041. The two ends of the second bolt hole 3044 penetrate the two end faces of the connecting arm 3041 respectively. While penetrating the connecting arm 3041, the second bolt hole 3044 also passes through the rectangular hole 3031 and the concave hole 3032 on the connecting arm 3041. This allows the second bolt 3045 to pass through the rectangular block 5 and the concave block 6 when penetrating the connecting arm 3041, effectively preventing the rectangular block 5 and the concave block 6 from falling off, thus improving the locking effect of the connecting member 303 and the support member 304. To prevent the second bolt 3045 from falling out of the second bolt hole 3044, a nut 3046 is tightened at the tail of the second bolt 3045. In this invention, while ensuring that the connecting arm 3041 is inserted into the connecting member 303, the connecting member 303 can also be rectangular or other shapes.

[0062] like Figure 5 As shown, in order to facilitate the installation of the curtain wall panel 8 on the support member 304, a connecting plate 3043 is also welded on the two support legs 3042. The connecting plate 3043 can be any shape such as rectangular, circular, or fan-shaped, and the connecting plate 3043 is also provided with through holes for bolts to pass through, or the connecting plate 3043 is provided with threaded connecting bolts. The number of through holes or connecting bolts can be selected as needed, so that the curtain wall panel 8 can be directly fixed to the support leg 3042 by connecting bolts during installation, making the installation of the curtain wall panel 8 more convenient.

[0063] like Figure 7 As shown, during the insertion of the rectangular component into the rectangular hole 3031 and the insertion of the concave block 6 into the concave hole 3032, they simultaneously connect with the sector plate 3021 in the rotating component 302. Furthermore, the second bolt 3045, while being screwed into the connecting arm 3041, passes through the rectangular block 5 and the concave block 6. This causes the connecting component 303, the support component 304, and the rotating component 302 to elastically clamp together and be pressed into the grooved track 3026 on the sector plate 3021, forming the rotating structure 3. The connecting arm 3041 of this rotating structure 3 is fixed in its pivot position on the rotating component 302. The rectangular block 5 and the concave block 6 engage with the rotating component 302, and by manually pressing with sufficient force in the circumferential direction, the connecting arm 3041 can pivot to another pivot position. This clamping device-like fixation prevents internal forces from pivoting, improving the overall stability of the structure and facilitating angle control of the curtain wall structure.

[0064] In this invention, when the curtain wall panel 8 is rectangular, there are four fixing structures 7, which are located at the four right angles of the current panel. For example... Figure 8 , Figure 9 As shown, the fixing structure 7 includes two channel steels 702. The outer end of one channel steel 702 is connected to the building base 2, and the outer end of the other channel steel 702 is connected to the curtain wall panel 8. Both channel steels 702 have multiple elongated holes 704, which are evenly spaced along the axial direction of the channel steel 702. When the two channel steels 702 are installed on the building base 2 and the curtain wall panel 8 respectively, locking bolts are installed in the corresponding elongated holes 704 on the two channel steels 702 to lock and fix them. When the tilt of the curtain wall panel 8 needs to be adjusted, the locking bolts are removed. After the tilt of the curtain wall panel 8 is adjusted, the locking bolts are reinstalled in the corresponding elongated holes 704 on the two channel steels 702 to lock them in place. Of course, in order to make the fixed structure 7 more secure, when there are multiple corresponding elongated holes 704 on the two channel steels 702, locking bolts can be installed in all of the multiple corresponding elongated holes 704, or two or three corresponding elongated holes 704 can be selected to install locking bolts.

[0065] To ensure a more stable connection between the two channel steels 702, which are arranged back-to-back, a flat steel 703 can be placed between them. The width of the flat steel 703 matches the width of the channel steel 702, and it also has multiple elongated holes 704. The spacing between two adjacent elongated holes 704 on the flat steel 703 is equal to the spacing between two adjacent elongated holes 704 on the channel steel 702. When it is necessary to lock and fix the two channel steels 702, the locking bolts pass through the elongated holes 704 on both channel steels 702 and the flat steel 703 for locking. To prevent the flat steel 703 from falling off during adjustment, it can be directly welded to one of the channel steels 702.

[0066] The outer end of the channel steel 702 is fitted with angle steel 701 that connects to the curtain wall panel 8 or the building base 2. To make the connection between the channel steel 702 and the curtain wall panel 8 or the building base 2 more stable, there are two angle steels 701 at the outer end of the channel steel 702, located on opposite sides of the channel steel 702. To further strengthen the connection between the channel steel 702 and the angle steel 701, a flat steel 703 can also be placed between the channel steel 702 and the angle steel 701. Both the flat steel 703 and the angle steel 701 can be directly welded and fixed to the channel steel 702.

[0067] It should be noted that the bolts mentioned in this invention are all friction-type high-strength bolts, in order to further improve the overall stability of the connection structure.

[0068] When the curtain wall panel 8 needs to be installed, first use the keel bolt 3012 to fix the rotating part 302 to the building base 2, then pass the inner ends of the two grooved parts 301 through the groove hole 3027, so that the inner end of one grooved part 301 is inserted into the wedge hole 3013 of the inner end of the other grooved part 301, and then use the keel bolt 3012 to fix the outer ends of the two grooved parts 301 to the building base 2 respectively.

[0069] Insert the connector 303 between the two sector plates 3021 in the rotating member 302, and use the first bolt 4 to install the inner end of the connector 303 onto the rotating member 302; insert the connecting arm 3041 of the support member 304 into the connector 303, and align the rectangular hole 3031 on the connector 303 with the rectangular hole 3031 on the connecting arm 3041, and align the concave hole 3032 on the connector 303 with the concave hole 3032 on the connecting arm 3041; insert the rectangular block 5 into the arc hole 3025 and the connector 3021. The rectangular holes 3031 on the 3 and 3041 on the connecting arm are inserted into the rectangular holes 3031 on the 3 and 3041 on the connecting arm, so that the protrusion 501 on the rectangular block 5 rubs against the wall of the arc-shaped hole 3025. The concave block 6 is inserted into the concave holes 3032 on the connecting part 303 and 3032 on the connecting arm 3041, so that the step shoulder on the concave block 6 engages with the groove track 3026. The second bolt 3045 is axially passed through the connecting arm 3041, and through the rectangular block 5 and the concave block 6. The tail of the second bolt 3045 is locked by the nut 3046.

[0070] Angle steel 701 is bolted to channel steel 702, with the two channel steels 702 arranged back to back. Flat steel 703 is placed between the two channel steels 702. Finally, locking bolts are used to lock the two channel steels 702 and the flat steel 703 together, completing the assembly of the fixed structure 7. Angle steel 701 at one end of channel steel 702 in the assembled fixed structure 7 is bolted to the building base 2.

[0071] The connecting plates 3043 at the upper ends of the two support legs 3042 are fixed to the curtain wall panel 8 with connecting bolts, and the angle steel 701 at one end of the channel steel 702 in the fixing structure 7 is fixed to the curtain wall panel 8 with bolts.

[0072] When the tilt of the curtain wall panel 8 needs to be adjusted, first remove the locking bolts that secure the two channel steels 702 in the fixing structure 7, so that the channel steels 702 connected to the curtain wall panel 8 in the fixing structure 7 can move with the rotation of the curtain wall panel 8; then, loosen the nut 3046 that secures the second bolt 3045, unscrew the second bolt 3045 from the second bolt hole 3044, pull out the rectangular block 5 and the concave block 6, rotate the connecting piece 303, and the connecting piece 303 drives the support piece 304 and the curtain wall panel 8 to rotate synchronously, so that the curtain wall... The tilt of panel 8 is adjusted; when the tilt of curtain wall panel 8 is rotated to the required angle, the rotation of connector 303 is stopped, and rectangular blocks 5 are inserted into the arc hole 3025 on the arc plate, the rectangular hole 3031 on connector 303 and the rectangular hole 3031 on support 304. Concave blocks 6 are inserted into the concave holes 3032 of connector 303 and support 304, and the step shoulder of concave block 6 is engaged with groove track 3026, so that the curtain wall panel 8 after the tilt angle is adjusted is locked.

[0073] Finally, the second bolt 3045 is axially passed through the connecting arm 3041, and through the rectangular block 5 and the concave block 6. The tail of the second bolt 3045 is locked with the nut 3046. The locking bolts are then tightened together in the corresponding elongated holes 704 on the two channel steels 702 in the fixing structure 7, thus locking and fixing the two channel steels 702 in the fixing structure 7, further fixing the curtain wall panel 8, and completing the adjustment of the curtain wall panel's tilt angle. Figure 10 As shown.

[0074] By using the structural curtain wall panel 8 described in this invention for fixing, the stability is good and the installation is convenient. At the same time, it reduces the construction difficulty of erecting the inclined curtain wall, avoids shear damage caused by too many bolts on the members, and improves the recycling rate of structural components while meeting the accuracy control index requirements, thereby reducing the construction difficulty and project cost.
