Description

Technical Field

[0001] This application belongs to the field of curtain wall technology, specifically relating to a docking device for splicing and installing curtain wall units. Background Technology

[0002] As an external envelope or decorative structure of a building, curtain walls, while not bearing the load of the main structure, possess multiple functions such as windproofing, rainproofing, heat insulation, fireproofing, lightning protection, and earthquake resistance. Depending on the construction method, curtain walls can be divided into component-based and unitized types. Among them, unitized curtain walls have become the mainstream choice in modern architecture due to their high installation efficiency. However, during on-site installation, the quality of the connection between each unit directly affects the overall structural stability of the curtain wall. Therefore, high-precision curtain wall connection devices are crucial.

[0003] Patent application number 202322740367.4 discloses a splicing curtain wall structure with high alignment and convenient installation. It includes a clamping slide and a supporting slide arranged vertically, and a lifting slide column with adjustable spacing positioned between them. Correspondingly, sliding strips that mate with the slide grooves are provided at the upper and lower ends of the curtain wall; abutting side plates are provided between adjacent curtain walls, and the upper and lower ends of the abutting side plates and sliding strips are respectively provided with matching mating inserts and holes, achieving fixation through plug-in connection. During installation, the curtain wall units and the abutting side plates are simply slid into the slide grooves sequentially, and the mating inserts are inserted into the holes. Then, the lifting slide column is adjusted to reduce the spacing between the upper and lower slides, thus completing the clamping and high-precision splicing of the curtain wall. This solution not only simplifies the traditional curtain wall installation process and improves construction efficiency, but also effectively ensures the splicing accuracy between curtain wall units through a mechanical limiting structure.

[0004] However, this modular curtain wall structure still has certain limitations in practical applications. On the one hand, multiple curtain wall units are fixed by a shared set of clamping and supporting carriages, resulting in a relatively concentrated support structure and uneven stress distribution. Under external disturbances, it is prone to loosening, leading to insufficient overall stability and potential safety hazards. On the other hand, the curtain walls are tightly connected by structures such as sliding strips, embedded columns, and embedded holes, making it difficult to quickly disassemble and replace individual units during maintenance. This results in poor flexibility and higher maintenance costs in the later stages. Utility Model Content

[0005] The purpose of this application is to provide a curtain wall connection device with high stability and ease of assembly and disassembly, which is achieved through the following technical solution: A curtain wall docking device includes linear guide groove assemblies disposed at the upper and lower ends of the curtain wall, and filling sealing members continuously arranged along the length of the splice joint of adjacent curtain walls; the curtain wall docking device further includes a support anchoring assembly for fixing the linear guide groove assembly to the building; the linear guide groove assembly is disposed on either curtain wall, and an anchoring compensation mechanism for adjusting adjacent curtain walls to make their wall surfaces lie on the same plane is provided between the support anchoring assembly and the linear guide groove assembly.

[0006] Preferably, the filling sealing member is provided with a set of receiving cavities that are mirror-symmetrically distributed along its longitudinal axis of symmetry and are respectively embedded into the sides of adjacent curtain walls; the filling sealing member also includes a barrier portion that physically isolates the set of receiving cavities, and the receiving cavity is provided with elastic abutment components at both ends that abut against the barrier portion and the sides of the curtain wall respectively.

[0007] Preferably, the elastic abutment component includes a force-applying surface that is at least partially fitted to the side of the curtain wall so that the curtain wall is clamped between a corresponding set of elastic abutment components, and a force-transmitting wing surface that extends along both sides of the force-applying surface toward the blocking part and connects with the side wall of the receiving cavity; a flexible buffer is also provided at the position where the force-applying surface and the curtain wall are fitted.

[0008] Preferably, the linear guide groove assembly is sandwiched between adjacent filler sealing members at both ends, and a vibration transmission surface is formed at the junction of the two; and the curtain wall docking device also includes a shock-absorbing anchoring assembly for fixing the filler sealing member to the building.

[0009] Preferably, the vibration damping anchoring assembly includes a first vibration conductor disposed on the surface of the filling sealing member near the building, and a second vibration conductor that is telescopically connected to and fixed to the building; the first vibration conductor and the second vibration conductor are provided with dampers in the telescopic direction for providing damping force to the telescopic movement and suppressing vibration response.

[0010] Preferably, the first vibration transmission component includes a connecting base disposed in the middle of the filling sealing component, and lateral extensions extending from the upper and lower sides of the connecting base in a direction away from the curtain wall, the ends of the lateral extensions converging to form mounting holes; and the second vibration transmission component includes a set of force transmission pins corresponding to the mounting holes, one end of the force transmission pins being fixedly connected to the building.

[0011] Preferably, the force transmission pin is connected to an actuating surface on the side near the curtain wall; the two ends of the damper are respectively disposed between the connecting base and the actuating surface, and an elastic reset member is wrapped around the outside of the damper; the two ends of the actuating surface and / or the surface on the side away from the curtain wall form a limiting fit with the lateral extension.

[0012] Preferably, the anchoring compensation mechanism includes an adjusting screw disposed on the linear guide slide assembly, and an internally threaded sleeve disposed on the support anchoring assembly and forming a retractable screw-in connection with the adjusting screw.

[0013] Preferably, the anchoring compensation mechanism further includes at least one set of guide carriages disposed on the linear guide slide assembly; the supporting anchoring assembly is provided with a fixed guide rail that slides with the guide carriages, and the fixed guide rail and the guide carriages together constitute a limiting and guiding structure.

[0014] Preferably, the linear guide chute assembly includes a receiving cavity for accommodating the curtain wall, and a roller is disposed inside the receiving cavity.

[0015] Compared with the prior art, this application has the following beneficial effects: This application, by individually configuring each curtain wall unit with a matching linear guide groove assembly and anchoring compensation mechanism, can not only greatly increase the convenience of maintenance, but also ensure that the curtain wall units that are independently fixed to the building can be adjusted to be on the same plane, thereby facilitating the installation of infill sealing components, and further increasing the overall stability of the curtain wall with the help of infill sealing components.

[0016] This application enables adjacent curtain wall panels to be spliced ​​and fixed within the same infilled sealing member by setting receiving cavities that are mirror-symmetrically distributed along the barrier section. Simultaneously, the inclusion of elastic abutment components within the receiving cavities effectively prevents sealing defects or loosening caused by rigid contact between the curtain wall and the barrier section, and also prevents damage to the curtain wall material that may occur with traditional rigid connections, thereby improving the overall sealing, stability, and safety of the curtain wall system.

[0017] This application incorporates a force-applying surface on the elastic abutment component for applying pressure to the curtain wall, and extends force-transmitting wing surfaces on both sides of the force-applying surface to connect with the sidewalls of the receiving cavity. This allows the elastic abutment component to effectively transmit pressure to the barrier portion under stress. This structure not only achieves stable clamping and sealing of the curtain wall unit, but also enhances the overall strength and structural stability of the elastic abutment component through the design of the force-transmitting wing surfaces, thereby improving the adaptability and durability of the curtain wall connection device in complex environments.

[0018] This application clamps the two ends of the linear guide slide assembly between adjacent filling sealing members and sets a vibration transmission surface at the contact point. The vibration generated after the curtain wall unit completes the position adjustment can be effectively transmitted and buffered through this structural design, thereby reducing the impact of vibration on the overall structure and significantly improving the stability and seismic performance of the curtain wall docking device.

[0019] This application, by setting up a retractable first vibration transmission component and a second vibration transmission component, and configuring a damper on their connection path, enables the curtain wall system to absorb part of the vibration energy through the damper when subjected to wind loads or seismic disturbances, thereby reducing stress concentration at the joints and effectively alleviating the technical problem of easy breakage of the curtain wall joints under external forces, and significantly improving the safety and durability of the curtain wall structure.

[0020] This application designs the first vibration transmission component to have lateral extensions distributed vertically, and cooperates with a set of force transmission pins in the second vibration transmission component, so that the vibration energy from the linear guide groove assembly can be transmitted evenly and stepwise in the shock-absorbing anchoring assembly, thereby effectively alleviating the stress concentration problem caused by external force disturbance at the joint.

[0021] This application constructs a vibration damping and force transmission system that combines buffering, energy dissipation, and limiting functions by setting an actuating surface on the side of the force transmission pin closest to the curtain wall and connecting the two ends of the damper to the connecting base of the first vibration conductor, respectively. Simultaneously, the two ends of the actuating surface and the surface facing away from the curtain wall form a limiting fit with the lateral extension. This design significantly improves the force transmission stability between the first and second vibration conductors, enabling efficient and controllable energy transmission and structural response under external vibration, further enhancing the safety and durability of the curtain wall connection device in complex environments.

[0022] The anchoring compensation mechanism of this application, through the setting of an adjusting screw and an internally threaded sleeve screwed to it, can precisely adjust the position of the curtain wall and ensure good stability of the adjusted structure. On this basis, a limiting guide structure composed of a fixed guide rail and a guide slide is further set, which not only improves the stability of the curtain wall during installation and use, but also effectively reduces the shaking caused by external disturbances.

[0023] This application utilizes a roller structure within the receiving cavity of a linear guide chute assembly. During the installation, adjustment, or replacement of curtain wall units, this roller enables smooth sliding of the curtain wall within the chute. Compared to traditional pure sliding friction, the rolling support of the roller significantly reduces pushing resistance, improving operational convenience and guiding accuracy. Simultaneously, this design helps reduce wear between the chute and the curtain wall, extending the device's service life. It is suitable for curtain wall systems with high requirements for installation efficiency and ease of subsequent maintenance. Attached Figure Description

Specifically, the elastic abutment component 330 includes a force-applying surface 331 that is at least partially fitted to the side of the curtain wall 100 so that the curtain wall 100 is clamped between a corresponding set of elastic abutment components 330, and a force-transmitting wing surface 332 that extends along both sides of the force-applying surface 331 toward the blocking part 320 and connects with the side wall of the receiving cavity 310; a flexible buffer 340 is also provided at the position where the force-applying surface 331 and the curtain wall 100 are fitted.

[0028] In this embodiment, to increase the stability of the curtain wall side, the linear guide groove assembly 200 is sandwiched between adjacent filling-type sealing members 300 at both ends, and a vibration transmission surface is formed at the junction of the two; and the curtain wall docking device also includes a shock-absorbing anchoring assembly 600 for fixing the filling-type sealing member 300 to the building. Specifically, the shock-absorbing anchoring assembly 600 includes a first vibration transmission member 610 disposed on the surface of the filling-type sealing member 300 near the building, and a second vibration transmission member 620 telescopically connected to the first vibration transmission member 610 and fixed to the building; the first vibration transmission member 610 and the second vibration transmission member 620 are provided with dampers 630 in the telescopic direction for providing damping force to the telescopic movement and suppressing vibration response. The first vibration conductor 610 includes a connecting base 611 disposed in the middle of the filling sealing member 300, and lateral extensions 612 extending from the upper and lower sides of the connecting base 611 in a direction away from the curtain wall 100. The ends of the lateral extensions 612 converge to form mounting holes. The second vibration conductor 620 includes a set of force transmission pins 621 corresponding to the mounting holes. One end of the force transmission pins 621 is fixedly connected to the building. An actuating surface 622 is connected to the side of the force transmission pins 621 near the curtain wall 100. The two ends of the damper 630 are respectively disposed between the connecting base 611 and the actuating surface 622, and an elastic reset member 640 is wrapped around the outside of the damper 630. The two ends and / or the surface of the actuating surface 622 away from the curtain wall 100 form a limiting fit with the lateral extensions 612.

[0029] In this embodiment, the curtain wall docking device further includes a support anchoring component 400 for fixing the linear guide track assembly 200 to the building; the linear guide track assembly 200 is disposed on any one of the curtain walls 100, and an anchoring compensation mechanism 500 for adjusting adjacent curtain walls 100 to be on the same plane is also provided between the support anchoring component 400 and the linear guide track assembly 200. The anchoring compensation mechanism 500 includes an adjusting screw 510 disposed on the linear guide track assembly 200, and an internally threaded sleeve 520 disposed on the support anchoring component 400 and forming a retractable screw-engaged connection with the adjusting screw 510.

[0030] During installation, the support anchoring components 400 are first pre-embedded and fixed to the building structure. Then, the linear guide chute components 200 and the support anchoring components 400 are connected and assembled to form a vertically distributed curtain wall 100 guide installation system. Next, the curtain wall units are smoothly slid into the upper and lower sets of linear guide chute components 200 along the rollers 210 until both ends of the curtain wall extend to the sides of the chute components, completing the initial positioning. The above steps are repeated to complete the installation of multiple sets of curtain wall units and linear guide chute components 200. Subsequently, the anchoring compensation mechanism 500 is activated to fine-tune and correct each curtain wall unit, ensuring that the outer surfaces of multiple curtain walls 100 are on the same plane, improving the overall appearance flatness and splicing quality. Afterwards, filling sealing components 300 are installed between adjacent curtain wall units, and shock-absorbing anchoring components 600 are set on the sealing components, enabling the curtain wall units to achieve both sealing and stable structural fixation. Finally, the second vibration transmission element 620 in the vibration damping anchoring assembly 600 is connected and fixed to the main building structure, thereby completing the installation of the entire curtain wall docking device. In other embodiments, the second vibration transmission element 620 can be pre-fixed to the building first, and then its connection with the first vibration transmission element 610 can be established to adapt to the installation requirements under different construction conditions.

[0031] During later maintenance, only the damping anchoring component 600 and the filling sealing component 300 need to be removed sequentially, followed by reverse adjustment of the anchoring compensation mechanism 500, to slide the target curtain wall 100 into the building, achieving a rapid replacement operation without the assistance of external hoisting equipment. This design not only improves the installation accuracy and structural stability of the curtain wall system, but also greatly enhances the convenience and economy of later maintenance.
