Description

Technical Field

[0002] In modern architecture, curtain wall systems, as a crucial component, not only need to meet aesthetic and energy-saving requirements but also bear significant load-bearing and force-transfer functions. With accelerating urbanization and continuously increasing building heights, the application of curtain wall systems is becoming increasingly widespread, and their safety is directly related to the overall stability of the building and the safety of life and property of its users.

[0003] The safety of a curtain wall system largely depends on the reliability of its connection components. These connection nodes, typically located between columns, are responsible for transferring and distributing forces and stresses caused by external factors such as wind loads and earthquakes. In high-rise buildings or large-span curtain wall systems, the load-bearing capacity and durability of these connection nodes are particularly important. However, existing curtain wall connection components have many shortcomings in design and material selection.

[0004] First, under dynamic loads such as strong winds and earthquakes, traditional connection components are prone to loosening, deformation, or even failure. Such failures not only affect the overall stability of the curtain wall system but may also jeopardize the building's safety. Second, some traditional connection methods use a single material (such as aluminum alloy or ordinary steel), which, while offering advantages in lightweighting, often lacks sufficient strength and durability to withstand complex and variable external load conditions. Furthermore, existing technologies present certain complexities and high technical requirements during installation and maintenance; once damage occurs, repairs are difficult, further impacting the lifespan of the curtain wall system.

[0005] According to relevant building codes and safety standards, the connection nodes of curtain wall systems need to have sufficient load-bearing and deformation capacity to ensure stability under various extreme conditions. However, existing solutions often struggle to simultaneously meet the requirements of high strength, high durability, and ease of installation. Therefore, developing a curtain wall mullion connection assembly that can effectively improve connection strength, extend service life, and is easy to install and maintain is particularly urgent.

[0046] Specifically, the principle of this utility model is as follows:

[0047] Preparation: Before starting installation, ensure all components are complete, including the column body, mounting plate, connecting blocks, limit blocks, and fastening components. Inspect all parts for damage or defects, especially critical areas such as threaded holes, dovetail grooves, and guide rails. Prepare installation tools such as wrenches, screwdrivers, and welding equipment.

[0048] Installing the mounting plate: First, align the dovetail block of the mounting plate with the dovetail groove in the mounting slot of the column body, and insert the mounting plate into the mounting slot along the guide rail. Due to the matching design of the dovetail groove and dovetail block, the mounting plate can slide smoothly into place, ensuring a firm connection between the mounting plate and the column body. The rectangular plate structure of the mounting plate provides a large contact area, enhancing the stability of the connection.

[0049] Welding the fixing plate and connecting block: Align the upper end of the vertical part of the connecting block with the lower surface of the fixing plate, and weld them together using welding equipment. During welding, ensure that the weld is uniform and strong. After welding, chamfer the weld to eliminate stress concentration and improve the durability of the connection.

[0050] Install the limiting block: Align the vertical portion of the limiting block with the outer wall of the column body and secure it using welding or bolts. The L-shaped structure of the limiting block effectively restricts the position of the connecting block, preventing displacement under stress. The anti-slip texture (herringbone arrangement) on the horizontal portion of the limiting block increases friction, preventing the fastening components from loosening under vibration or external force.

[0051] Connecting block and limiting block: Align the boss of the connecting block with the slotted through hole of the limiting block, ensuring that the threaded hole on the boss is aligned with the slotted through hole. The boss of the connecting block has a trapezoidal structure, and the axis of the threaded hole is perpendicular to the inclined surface of the boss. This design helps to distribute stress and improve the strength of the connection. The cross-shaped reinforcing ribs on the upper surface of the transverse portion of the connecting block further enhance its bending and torsional resistance.

[0052] Fastening assembly installation: Pass the fastening bolt through the slotted hole of the limit block and screw it into the threaded hole on the boss of the connecting block. Since the threaded portion of the fastening bolt is longer than the total thickness of the limit block and the connecting block, it ensures the bolt passes completely and is securely connected. Use a wrench to tighten the fastening nut, ensuring a tight connection between the connecting block and the limit block. The fastening nut features a self-locking design, effectively preventing loosening under vibration or external force.

[0053] Inspection and Adjustment: After installation, check that all connections are secure and that there is no looseness or misalignment. Pay special attention to the reinforcing ring on the inner wall of the slotted through-hole of the limit block, ensuring it is perpendicular to the length of the through-hole to enhance its strength and durability. If any problems are found, adjust or retighten them promptly.

[0054] Final Acceptance: After confirming that all connections are secure and reliable, conduct the final acceptance inspection. Check whether the guide protrusions on both sides of the mounting groove of the column body fit well with the guide grooves on both sides of the fixing plate to ensure the stability and safety of the entire connection assembly.

[0055] This curtain wall mullion connection assembly, through meticulous design and a reasonable installation procedure, ensures a secure connection and long-term stability for the curtain wall mullions. The design of the fit between components, such as dovetail grooves and dovetail blocks, guide ridges and guide grooves, and reinforcing ribs and anti-slip textures, greatly improves the reliability and durability of the connection. By strictly following the above steps during installation, the curtain wall mullion connection assembly can be guaranteed to perform excellently in actual use, meeting the safety and aesthetic requirements of building curtain walls.
