A curtain wall decorative wing connecting structure

Abstract

This application belongs to the technical field of building structure connection devices, specifically relating to a curtain wall decorative wing connection structure. This application forms a bidirectional anti-detachment constraint structure by setting an intercepting surface below the transition groove and an anti-detachment cap above it, thus solving the problem that traditional single-limiting designs cannot cope with the risk of multi-directional outdoor displacement, while retaining the angle adjustment function of the clamping component around the rotating shaft. This achieves the dual technical goals of high reliability and adjustable angle. The intercepting surface directly abuts against the lower wall of the rotating shaft, effectively limiting the downward displacement of the rotating shaft. The anti-detachment cap, embedded in the upper opening of the transition groove and fixed to the transition component, blocks the upward detachment path of the rotating shaft. This bidirectional constraint significantly reduces the risk of curtain wall decorative wings falling off due to outdoor wind pressure, vibration, and other factors.

Description

Technical Field

[0001] This application belongs to the technical field of building structure connection devices, specifically relating to an adjustable curtain wall decorative wing connection structure. Background Technology

[0002] As a core component of modern building facades, curtain walls are a crucial system integrating architectural aesthetics, structural safety, and functional practicality. They not only fulfill basic functions such as providing shelter from wind and rain and thermal insulation, but also serve as an important medium for shaping a building's unique visual style. With the development of the construction industry, architects' demands for innovation and personalization in building exteriors are constantly increasing, leading to the widespread application of decorative curtain walls with decorative wing designs in high-end commercial complexes, cultural venues, and landmark buildings.

[0003] In practical engineering applications, to meet architects' pursuit of the overall aesthetic style of a building, the design of curtain wall decorative wings often needs to break through the limitations of a single angle. Some buildings require curtain wall decorative wings to be designed with different fixed angles to adapt to the folded or curved shapes of the building facade; even more extreme cases involve designing decorative wings with angles that gradually change along the building's height or horizontal direction, enhancing the building's artistic expression through dynamic visual changes. However, traditional curtain wall decorative wing connection methods are difficult to adapt to such complex design requirements—they typically use adapters extending from the curtain wall vertical frame and then directly connecting to the decorative wings via bolts. The limitations of this connection method are quite obvious: when decorative wings require multiple angles, adapters of different specifications must be customized for different angles, resulting in a diversification of adapter types. This not only requires the development of multiple sets of molds, generating high mold development and manufacturing costs, but also increases the difficulty of controlling processing precision due to the complexity of the parts. Furthermore, during on-site installation, workers need to perform differentiated operations on adapters with different angles, significantly extending the construction cycle and reducing installation efficiency.

[0004] To address the shortcomings of traditional connection methods, patent application number 201811025880.2 discloses an angle-adjustable decorative wing installation structure, providing an innovative solution for the multi-angle design and installation of curtain wall decorative wings. Its core lies in the mating structure of the aluminum alloy support and connectors: the aluminum alloy support has rotating shaft grooves on both its upper and lower sides, with pre-reserved openings at the outer ends of the grooves. The rotating shafts of the bottom and top connectors can be directly inserted into the aluminum alloy support through these openings, forming a rotatable connection. Simultaneously, limiting pins within the rotating shaft grooves firmly lock the rotating shafts, effectively preventing the bottom and top connectors from slipping off the aluminum alloy support during rotation or use, ensuring the stability of the structural connection. Through this design, the decorative wing can achieve angle adjustment by rotating the connectors around the rotating shafts, eliminating the need for customized adapters for different angles. This fundamentally reduces the number of molds required, lowers production costs, and simplifies the processing flow and on-site installation, providing an efficient and economical implementation path for decorative wing designs with complex and gradually changing angles. However, in actual engineering applications, curtain wall decorative wings are exposed to complex outdoor environments for a long time. Relying solely on a single limiting nail anti-detachment design is insufficient to cope with the risk of displacement in multiple directions. This not only increases the frequency and cost of later maintenance, but may also lead to safety accidents due to sudden shaft detachment problems, reducing the reliability and applicability of the installation structure in actual engineering projects. Utility Model Content

[0005] The purpose of this application is to provide a curtain wall decorative wing connection structure with high reliability and adjustable connection angle, which is achieved through the following technical solution: A curtain wall decorative wing connection structure includes a transition member protruding from the gap between two adjacent curtain walls. One end of the transition member is fixedly connected to the curtain wall frame, and the other end has a transition groove. A clamping member is rotatably connected to the transition groove. The clamping member includes a rotating shaft built into the transition groove, a fixing member for fixing the curtain wall decorative wing, and a connecting member connecting the rotating shaft and the fixing member. An opening that mates with the connecting member is provided on the groove wall of the transition groove. The opening size is smaller than that of the rotating shaft. A mating groove is provided at the position where the transition groove meets the rotating shaft. A limiting member is provided through the mating groove. The transition member also includes an intercepting surface for abutting against the lower wall of the rotating shaft in the installed state to prevent it from moving downward relative to the transition groove. Furthermore, the transition member is equipped with an anti-detachment cap. The anti-detachment cap is partially embedded in the upper opening of the transition groove and forms an upper limit after being fixed with the transition member to prevent the curtain wall decorative wing from detaching.

[0006] Preferably, the fastener includes a pair of mounting wing plates extending symmetrically outward from the connector, the two mounting wing plates forming a decorative wing insert groove between their opposite inner sidewalls.

[0007] Preferably, at least one set of positioning holes is provided at the corresponding position of the mounting wing plate; a through mounting hole is pre-set at the corresponding position of the curtain wall decorative wing, and the two are fixed by mechanical fasteners passing through the positioning hole and the through mounting hole.

[0008] Preferably, the curtain wall frame includes a main body that connects to the main structure of the building, a curtain wall mounting part for fixing adjacent curtain walls, and a transition fixing part for fixing transition components.

[0009] Preferably, the transition fixing part includes a cantilever arm extending from the main body towards the gap between the curtain walls; the transition component includes a clamping connecting groove that cooperates with the cantilever arm to achieve a fixed connection between the two.

[0010] Preferably, the connection structure further includes a set of force-transmitting lugs extending outward from the opening of the clamping connection groove, the force-transmitting lugs being anchored to the main body of the curtain wall frame by fasteners.

[0011] Preferably, the curtain wall mounting portion and the main body portion enclose each other to form locking grooves for accommodating the two ends of the force transmission lug; the side of the force transmission lug away from the main body portion abuts against the curtain wall mounting portion.

[0012] Preferably, the two adjacent curtain walls are fixedly connected on the side away from the curtain wall frame using corner bracket connectors.

[0013] Compared with the prior art, this application has the following beneficial effects: This application creates a bidirectional anti-detachment constraint structure by setting an intercepting surface below the transition groove and an anti-detachment cap above it, thus forming a bottom-tight upper limit position. This solves the problem that traditional single limit designs cannot cope with the risk of multi-directional outdoor displacement, while retaining the angle adjustment function of the clamping components around the rotating shaft, achieving the dual technical goals of high reliability and adjustable angle. The intercepting surface directly abuts against the lower wall of the rotating shaft, which can effectively limit the downward displacement of the rotating shaft. The anti-detachment cap is embedded in the upper opening of the transition groove and fixed with the transition component, which can block the upward detachment path of the rotating shaft. The bidirectional constraint greatly reduces the risk of curtain wall decorative wings falling off due to outdoor wind pressure, vibration and other factors.

[0014] This application utilizes a pair of mounting wing plates extending symmetrically outward from the connector, and at least one set of positioning holes and through mounting holes pre-set at corresponding positions of the mounting wing plates and the curtain wall decorative wing. First, the decorative wing is pre-positioned using the decorative wing mounting groove formed by the inner walls of the two mounting wing plates. Then, mechanical fasteners pass through the positioning holes and through mounting holes to form a double-fixing structure with rigid locking for pre-positioning. This ensures the stability of the connection between the curtain wall decorative wing and the clamping components, preventing displacement or loosening of the decorative wing during long-term use. Furthermore, the symmetrical design of the mounting wing plates and the precise matching of the positioning holes and through mounting holes make the installation and alignment of the curtain wall decorative wing more convenient. The connection method of the mechanical fasteners also facilitates the disassembly and replacement of the decorative wing as needed, balancing the reliability of the fixation with the flexibility of installation and maintenance.

[0015] This application refines the curtain wall frame into a main body that connects to the main structure of the building, a curtain wall mounting part for fixing adjacent curtain walls, and a transition fixing part for fixing transition components. The transition fixing part includes a cantilever arm extending from the main body towards the curtain wall gap, and the transition component is provided with a clamping connection groove that cooperates with the cantilever arm. This allows the transition component and the curtain wall frame to form a unique load-bearing structure that fits together in an assembly relationship. Compared with traditional general-purpose connection structures, this can transfer loads more accurately and has higher installation stability.

[0016] This application sets a set of outwardly extending force-transmitting lugs at the opening of the interlocking connection groove, allowing the force-transmitting lugs to be anchored to the main body of the curtain wall frame through fasteners. At the same time, the locking groove formed by the curtain wall mounting part and the main body accommodates both ends of the force-transmitting lugs, and the side of the force-transmitting lugs away from the main body abuts against the curtain wall mounting part, forming a triple fixing constraint of fastener anchoring, locking groove limiting, and side wall abutment. This not only strengthens the connection strength between the transition component and the curtain wall frame, but also disperses the load to avoid local stress concentration, resulting in higher installation stability.

[0017] This application achieves a fixed connection between two adjacent curtain walls by using corner brackets on the side away from the curtain wall frame. This eliminates the need for a single splice or a glued connection without dedicated connectors on the outer end of the curtain wall away from the frame. Instead, a rigid connection structure is formed through the corner brackets, which can effectively transmit the lateral force between adjacent curtain walls, limit relative displacement, and prevent the gap from widening or misalignment caused by factors such as outdoor wind pressure and temperature deformation, resulting in higher curtain wall stability.

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Those skilled in the art will be able to implement the present invention based on these descriptions. Furthermore, the embodiments of the present invention described below are generally only a part of the embodiments of the present invention, and not all of the embodiments. Therefore, all other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.

[0020] A curtain wall decorative wing connection structure includes a transition member 200 protruding from the gap between two adjacent curtain walls 100. One end of the transition member 200 is fixedly connected to the curtain wall frame 300, and the other end has a transition groove 210. A clamping member 400 is rotatably connected to the transition groove 210. The clamping member 400 includes a rotating shaft 410 built into the transition groove 210, a fixing member 420 for fixing the curtain wall decorative wing 500, and a connecting member 430 connecting the rotating shaft 410 and the fixing member 420. An opening that mates with the connecting member 430 is provided on the groove wall of the transition groove 210. The size of the opening is smaller than that of the rotating shaft 410. A mating groove is provided at the position where the transition groove 210 and the rotating shaft 410 meet. A limiting member 700 is provided through the mating groove. In use, the angle of the curtain wall decorative wing 500 can be adjusted by adjusting the connection angle between the adapter groove 210 and the rotating shaft 410, and by inserting the limiting member 700 into the corresponding docking groove.

[0021] To prevent the pivot 410 from detaching from the adapter groove 210 during longitudinal installation, in this embodiment, the adapter component 200 further includes an intercepting surface 220 for abutting against the lower wall of the pivot 410 in the installed state to prevent it from moving downward relative to the adapter groove 210. In addition, the adapter component 200 is also equipped with an anti-detachment cover 230, which is partially embedded in the upper opening of the adapter groove 210 and forms an upper limit after being fixed with the adapter component 200 to prevent the curtain wall decorative wing 500 from detaching.

[0022] In this embodiment, the fastener 420 includes a pair of mounting wing plates 421 extending symmetrically outward from the connector 430. The two mounting wing plates 421 enclose each other to form a decorative wing mounting groove 422 between their respective inner sidewalls. At least one set of positioning holes is provided at corresponding positions of the mounting wing plates 421; a through mounting hole is pre-set at a corresponding position of the curtain wall decorative wing 500. The curtain wall decorative wing 500 is fixed by mechanical fasteners passing through the positioning holes and the through mounting holes.

[0023] To improve the stability of the curtain wall 100 and curtain wall decorative wings 500 on the building facade, in this embodiment, the curtain wall frame 300 includes a main body 310 connected to the main structure of the building, a curtain wall mounting part 320 for fixing adjacent curtain walls 100, and a transition fixing part 330 for fixing the transition member 200. Specifically, the transition fixing part 330 includes a cantilever arm 331 extending from the main body 310 towards the gap between the curtain walls 100; the transition member 200 includes a clamping connection groove 240 that cooperates with the cantilever arm 331 to achieve a fixed connection between the two. The cooperation between the cantilever arm 331 and the clamping connection groove 240 can improve the operational stability of the curtain wall decorative wing connection structure. Furthermore, the adapter component 200 also includes a set of force-transmitting lugs 250 extending outward from the opening of the clamping connecting groove 240. The force-transmitting lugs 250 are anchored to the main body 310 of the curtain wall frame 300 by fasteners. Further, in this embodiment, the curtain wall mounting portion 320 and the main body 310 enclose and form locking grooves to accommodate the two ends of the force-transmitting lugs 250; the side of the force-transmitting lugs 250 away from the main body 310 abuts against the curtain wall mounting portion 320. Therefore, the adapter component will be stably installed on the curtain wall frame 300. Furthermore, the two adjacent curtain walls 100 are fixedly connected on the side away from the curtain wall frame 300 through corner bracket connectors 600. Therefore, the corner bracket connectors 600 can form an internal and external mating structure with the curtain wall frame 300. They are fixedly connected at the outer ends of the two adjacent curtain walls 100 away from the curtain wall frame 300. At the same time, the curtain wall frame 300 positions and constrains the curtain wall 100 through the inner curtain wall mounting part. The two form a double clamping and limiting from the inner and outer sides of the curtain wall 100, respectively, and finally achieve a more stable seal and lock for the gap between the curtain walls 100, preventing the gap from loosening due to external force or deformation.

[0024] During installation, simply insert the rotating shaft 410 of the clamping component 400 longitudinally into the adapter groove 210 of the adapter component 200 until the lower end of the rotating shaft 410 is fully in contact with the intercepting surface 220 built into the adapter groove 210, forming a lower limit. Then, rotate the rotating shaft 410 according to the curtain wall facade design requirements to adjust the curtain wall decorative wing 500 pre-installed on the clamping component 400 to a preset angle. After angle calibration, precisely insert the limiting component 700 into the mating groove along the gap between the adapter groove 210 and the rotating shaft 410. The relative position of the rotating shaft 410 and the adapter groove 210 is locked through physical engagement to prevent angle deviation. Finally, insert the lower end of the anti-detachment cover 230 into the upper opening of the adapter groove 210 to complete the upper anti-detachment sealing of the overall structure. At this point, the angle adjustment and installation fixing process of the curtain wall decorative wing 500 is completed.
