Description

Technical Field

[0001] The utility model relates to the technical field of double-layer curtain walls, in particular to a glass-steel grid double-layer curtain wall structure with welded connectors. Background Art

[0002] Double-skin curtain walls, a key component of modern building exteriors, have been widely adopted in high-rise and commercial buildings in recent years. Double-skin curtain walls typically consist of two layers of glass: the outer layer provides protection from wind, rain, and sunlight, while the inner layer provides thermal insulation, soundproofing, and safety. The gap between the two layers of glass allows for ventilation or forms an insulating layer, effectively improving the building's energy efficiency. Furthermore, double-skin curtain walls improve indoor comfort and reduce heating and cooling energy consumption, making them a key technology in green building design.

[0003] Shortcomings of existing technology

[0004] Although the existing glass-steel grille double-layer curtain wall structure has improved the aesthetics and protective performance of traditional curtain walls to a certain extent, there are still some technical deficiencies, as shown below:

[0005] Insufficient connection structure stability: The steel grille of existing glass-steel grille double-layer curtain walls is typically bolted or welded directly to the curtain wall's support frame. Due to the limited number of stress points and the simple connection method, the connection between the steel grille and the glass curtain wall is prone to loosening or deformation under strong wind loads or external forces, affecting the overall stability and safety of the structure.

[0006] Uneven force distribution: The connection between the steel grille and the glass curtain wall is typically designed to withstand only vertical deadweight and some horizontal wind forces. However, when subjected to complex, multi-directional forces (such as wind pressure, vibration, and accidental impact), the forces acting on the connection are uneven, which can easily lead to fatigue, deformation, or even fracture at the connection points. This uneven force distribution reduces the overall structure's impact resistance and increases safety risks.

[0007] Complex installation and maintenance: Existing curtain wall connection structures typically utilize complex welding or bolting methods, which not only increases the difficulty and time cost of installation but also complicates maintenance over time. Welded areas are susceptible to corrosion in harsh environments, especially materials like steel, which are prone to rust. This requires regular maintenance or replacement of connection components, increasing building operation and maintenance costs. Utility Model Content

[0044] See also Figure 1-5 , a double-skin curtain wall structure with glass-steel grille and welded connectors:

[0045] The double-layer glass curtain wall 1 is installed inside a rectangular grid on the outside of the exterior wall, which is separated by a number of positioning columns 2 and cross beams 3. The positioning columns 2 and cross beams 3 together form a stable frame system. The positioning columns 2 bear the main vertical supporting force, transferring the weight of the double-layer glass curtain wall 1 and possible external forces such as wind loads to the building's infrastructure. The cross beams 3 are arranged horizontally and interconnected with the positioning columns 2. Their main function is to separate and support the double-layer glass curtain wall 1 in the horizontal direction to prevent the glass curtain wall from deforming or displacing in the horizontal direction. This frame structure composed of the positioning columns 2 and cross beams 3 provides a stable supporting frame structure for the double-layer glass curtain wall 1, allowing the double-layer glass curtain wall 1 to be firmly installed on the exterior wall of the building, and also provides a positioning reference for the subsequent installation of the steel grille 4.

[0046] The steel grille 4 is distributed on the outside of the double-layer glass curtain wall 1. The steel grille 4 not only has a decorative effect, but also has a protective function to a certain extent. From a decorative point of view, it can add a unique visual effect to the appearance of the building, making the building appearance more beautiful and elegant. In terms of protection, it can prevent external objects from directly hitting the double-layer glass curtain wall 1, reducing the risk of glass damage. In terms of sunshade function, it can block part of the direct sunlight and reduce the energy consumption of indoor air conditioning. The steel grille 4 is connected to the two positioning columns 2 at the location by a welded connector 5. This connection method ensures that the steel grille 4 is tightly integrated with the frame structure of the double-layer glass curtain wall 1, so that the steel grille 4 can stably perform its various functions.

[0047] The welding connector 5 is a key component for connecting the steel grid 4 and the positioning column 2, and is composed of multiple parts.

[0048] The inner mounting frame 51 is mounted on the front end face of the positioning column 2. A positioning boss 511 is provided at the center of the mounting end face of the inner mounting frame 51. This positioning boss 511 is inserted into the positioning hole 21 provided on the front end face of the positioning column 2. The cooperation between the positioning boss 511 and the positioning hole 21 provides preliminary positioning, ensuring the accurate installation position of the inner mounting frame 51 on the positioning column 2, making subsequent connection operations more convenient and quick. Furthermore, the inner mounting frame 51 is specifically connected to the positioning column 2 via positioning bolts 52 provided at the upper and lower ends. The positioning bolts 52 further enhance the stability of the connection. They can withstand large tensile and shear forces, preventing the inner mounting frame 51 from loosening or shifting on the positioning column 2. When subjected to external forces, such as when the shaking of the double-glazed curtain wall 1 caused by wind is transmitted to the positioning column 2, the positioning bolts 52 ensure that the connection between the inner mounting frame 51 and the positioning column 2 remains secure and reliable.

[0049] The outer mounting frame 54 is mounted on the inner end surface of the steel grille 4. The upper and lower ends of the outer end surface of the outer mounting frame 54 are equipped with anti-mock protrusions 55, which plug into the corresponding anti-mock sockets 41 on the inner side of the steel grille 4. The coordination between the anti-mock protrusions 55 and the anti-mock sockets 41 is crucial. It not only facilitates the correct installation of the outer mounting frame 54 on the steel grille 4 and prevents incorrect installation, but also enhances the tightness of the connection. The center of the outer mounting frame 54 is positioned on the steel grille 4 via a centrally located mounting bolt 541. The mounting bolt 541 ensures a secure connection by firmly securing the outer mounting frame 54 to the steel grille 4, ensuring a stable connection between the outer mounting frame 54 and the inner mounting frame 51. If the steel grille 4 is subjected to external forces such as wind or collision, the mounting bolt 541 prevents the outer mounting frame 54 from detaching from the steel grille 4, thereby ensuring the stability of the entire curtain wall structure.

[0050] The X-shaped welded part 53 is welded between the inner mounting frame 51 and the outer mounting frame 54. The upper and lower ends of the front of the X-shaped welded part 53 are specifically welded to the upper and lower ends of the inner side of the outer mounting frame 54, and the upper and lower ends of the inner side of the X-shaped welded part 53 are specifically welded to the front side of the inner mounting frame 54 near the upper and lower ends to avoid the positioning bolts 52. This welding method forms a stable connection structure between the inner mounting frame 51 and the outer mounting frame 54. The X-shaped structural design of the X-shaped welded part 53 has good mechanical properties and can withstand external forces in multiple directions. When the steel grating 4 is subjected to forces from different directions, such as horizontal wind force, vertical deadweight or accidental impact force, the X-shaped welded part 53 can effectively transmit these forces to the inner mounting frame 51 and the outer mounting frame 54, and then transmit them to the positioning column 2 and the supporting structure of the steel grating 4 itself, thereby ensuring the stability and reliability of the entire connection structure.

[0051] The entire welded connector 5 is made of aluminum alloy. Aluminum alloy has the advantages of light weight, high strength, and corrosion resistance, and is suitable for use as a connecting component of this curtain wall structure. Its light weight helps to reduce the weight of the entire curtain wall structure, and the load-bearing requirements for the building structure are relatively reduced. It is also more convenient to operate during the installation process. The higher strength can meet the mechanical performance requirements required to connect the steel grille 4 and the positioning column 2, ensuring that the connection structure will not be easily damaged under various external forces. The corrosion resistance ensures the durability of the welded connector 5 when it is exposed to the external environment for a long time, such as rain, sunlight, air, etc., reduces maintenance costs, and extends the service life of the entire curtain wall structure.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
