Description

Technical Field

[0001] This invention relates to the field of building curtain wall technology, specifically to a multifunctional integrated curtain wall unit module connection structure. Background Technology

[0002] With the rapid development of the construction industry, curtain walls, as a core component of building facades, not only serve the function of decorating the building's appearance, but also need to meet multiple usage requirements such as heat preservation, sealing, waterproofing, earthquake resistance, and ventilation. Especially in high-rise buildings and large public buildings, higher requirements are placed on the connection stability, multi-functional integration, and construction convenience of curtain wall unit modules.

[0003] Currently, most existing curtain wall unit module connection structures adopt the traditional method of splicing main keels and secondary keels and fixing them with bolts. Although this can achieve basic connection and fixing functions, it still has many shortcomings in practical applications and is difficult to adapt to the diversified needs of modern buildings. First, the functionality of existing connection structures is relatively simple, mostly focusing only on connection stability and lacking integrated design for functions such as sealing, ventilation, and thermal insulation, resulting in limited overall curtain wall performance. For example, in some curtain wall connection structures, the sealing structure design between the main keel and secondary keel, and between the curtain wall body and supporting components, is simple, often using a single sealing strip. This easily leads to problems such as incomplete sealing, water leakage, and air leakage. Especially under severe weather conditions such as strong winds and heavy rain, the risk of leakage increases significantly, seriously affecting the comfort and safety of the building's interior environment. This is mainly due to the existence of gaps and channels at the sealing interface, unreasonable sealing design, and the lack of multiple sealing protection measures.

[0004] Secondly, existing curtain wall ventilation and moisture-proof designs have significant deficiencies. Most curtain wall keels lack dedicated ventilation structures, leading to condensation buildup inside the curtain wall that cannot be drained promptly, causing problems such as keel corrosion and decreased insulation performance. Simultaneously, the lack of effective water-absorbing and moisture-proof structures allows external moisture to seep in, easily causing the curtain wall to become damp and age, shortening its lifespan. While some open curtain walls have cavity structures, leakage is still difficult to prevent under drastic environmental changes, and the internal waterproof layer is prone to becoming riddled with holes due to the penetration of connecting components, making sealing extremely difficult. Therefore, those skilled in the art have provided a multifunctional integrated curtain wall unit module connection structure to solve the problems mentioned in the background art. Summary of the Invention

[0005] The purpose of this invention is to provide a multifunctional integrated curtain wall unit module connection structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multifunctional integrated curtain wall unit module connection structure, comprising a curtain wall body, a main keel, and a secondary keel;

[0007] Ventilation holes are provided on both the main keel and the secondary keel. Mounting components are bolted to both sides of one end of the secondary keel, and these mounting components are bolted to the main keel. Supporting components are bolted to both sides of the secondary keel, and each supporting component has a rubber pad that contacts the curtain wall body and the secondary keel. Fixing components are bolted to both the main keel and the secondary keel. Sealing support assemblies connected to the curtain wall body are provided on both sides of the fixing components. Each sealing support assembly includes a rigid support strip and a flexible sealing strip. The rigid support strip has several ventilation holes, and the flexible sealing strip has ventilation channels corresponding to the ventilation holes. These ventilation channels are unidirectional exhaust channels with a waterproof and breathable membrane on their inner wall. Decorative covers are snapped onto the fixing components.

[0008] Preferably, the mounting component is provided with a triangular support plate, which adopts a hollow lightweight structure and has several reinforcing ribs inside.

[0009] Preferably, both the main keel and the secondary keel have grooves on both sides, and the grooves have sealing edges, with the curtain wall body in contact with the sealing edges.

[0010] Preferably, the rubber pad is made of composite rubber material, and the surface of the rubber pad is provided with anti-slip texture.

[0011] Preferably, the rigid support strip is fixedly connected to the fastener, and the flexible sealing strip is wrapped around the outside of the rigid support strip, and the flexible sealing strip is in close contact with the curtain wall body and the fastener.

[0012] Preferably, the decorative cover has limiting edges on both sides, and the fixing member has connecting grooves on both sides for sliding connection of the limiting edges. A sealing layer is provided in the connecting groove, and the sealing layer is in contact with the limiting edges.

[0013] Preferably, a connector is provided between adjacent decorative covers, and the connector has engagement grooves at both ends for the decorative covers to engage. The decorative covers are provided with rubber strips that contact the curtain wall body.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention achieves integrated optimization of sealing, ventilation, and moisture-proof functions, effectively solving the technical pain points of existing curtain walls such as poor sealing, inadequate ventilation, and susceptibility to moisture and corrosion. By opening ventilation holes on the main and secondary keels, and cooperating with the air vents in the rigid support strips and the air vents in the flexible sealing strips of the sealing support components, a continuous ventilation path is formed, which can promptly drain the condensate accumulated inside the curtain wall, preventing keel corrosion and a decline in thermal insulation performance.

[0016] 2. This invention optimizes the stability, adaptability, and ease of construction of the connection structure, reduces construction costs, and facilitates later maintenance. The hollowed-out lightweight triangular support plate on the mounting component ensures support strength while achieving component lightweighting, reducing the overall load on the curtain wall, and the internal reinforcing ribs further enhance support stability.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1-5 The present invention provides a technical solution:

[0025] A multifunctional integrated curtain wall unit module connection structure includes a curtain wall body 1, a main keel 2, and a secondary keel 3.

[0026] Ventilation holes 4 are provided on both the main keel 2 and the secondary keel 3. The two sides of one end of the secondary keel 3 are connected to the mounting parts 5 by bolts. The mounting parts 5 are connected to the main keel 2 by bolts. The mounting parts 5 are provided with triangular support plates 15. The triangular support plates 15 adopt a hollow lightweight structure and have several reinforcing ribs inside. The two sides of the secondary keel 3 are connected to the support parts 6 by bolts. The support parts 6 are provided with rubber pads 7. The rubber pads 7 are in contact with the curtain wall body 1, the main keel 2 and the secondary keel 3. The rubber pads 7 are made of composite rubber and have anti-slip texture on the surface. The main keel 2 and the secondary keel 3 are both connected to the fixing parts 8 by bolts. The two sides of the main keel 2 and the secondary keel 3 are provided with grooves 16. The grooves 16 are provided with sealing edges 17, and the curtain wall body 1 is in contact with the sealing edges 17.

[0027] When connecting the curtain wall units, the main keel 2 and the secondary keel 3 are assembled first. The mounting parts 5 on both sides of one end of the secondary keel 3 are fixed to the main keel 2 with bolts. The triangular support plate 15 on the mounting part 5 is used to achieve stable support. The triangular support plate 15 adopts a hollow lightweight structure design, which reduces the overall weight while ensuring the support strength. The internal reinforcing ribs can further improve the structural stability, ensuring that the main keel 2 and the secondary keel 3 are connected in place. This reduces the overall load of the curtain wall and improves the stability of the connection, laying a solid foundation for the installation of subsequent components. Subsequently, sealing edges 17 are installed in the grooves 16 on both sides of the main keel 2 and the secondary keel 3. Then, the support 6 is fixed to both sides of the secondary keel 3 with bolts. The position of the support 6 is adjusted so that the rubber pad 7 on the support 6 is in close contact with the secondary keel 3 and the curtain wall body 1. The rubber pad 7 is made of composite rubber and has anti-slip texture on the surface. It can enhance the fit and play a good buffering and fixing role, avoid the curtain wall body 1 from direct contact with the keel and avoid wear caused by the keel. It can also reduce the damage to the curtain wall body 1 caused by external forces and improve the impact resistance of the structure. Compared with the traditional single support structure, it is more practical.

[0028] The fastener 8 has sealing support components on both sides that are connected to the curtain wall body 1. The sealing support components include a rigid support strip 9 and a flexible sealing strip 10. The rigid support strip 9 is fixedly connected to the fastener 8. The flexible sealing strip 10 is wrapped around the outside of the rigid support strip 9 and is in close contact with both the curtain wall body 1 and the fastener 8. The rigid support strip 9 has several vent holes 11. The flexible sealing strip 10 has vent channels 12 corresponding to the vent holes 11. The vent channels 12 are one-way exhaust channels and have a waterproof and breathable membrane on their inner walls. The fastener 8 has a decorative cover 14. The decorative cover 14 has limiting edges 18 on both sides. The fastener 8 has connecting grooves 19 on both sides for sliding connection of the limiting edges 18. The connecting grooves 19 have a sealing layer 20 in contact with the limiting edges 18. The sealing layer 20 is in contact with the limiting edges 18. A connector 21 is provided between adjacent decorative covers 14. The connector 21 has engaging grooves 22 at both ends for engaging with the decorative cover 14. The decorative cover 14 has a rubber strip 13 that contacts the curtain wall body 1.

[0029] The fastener 8 is bolted to the main keel 2 and the secondary keel 3. Sealing support components are installed on both sides of the fastener 8 to fix the rigid support strip 9 to the fastener 8. The flexible sealing strip 10 wraps around the outside of the rigid support strip 9 and fits against the curtain wall body 1 and the fastener 8. The rigid support strip 9 provides stable support for the curtain wall body 1, while the flexible sealing strip 10 achieves a tight seal. The two work together to ensure the reliability of the support and form an important sealing defense. The ventilation holes 4 on the main keel 2 and the secondary keel 3, together with the vent holes 11 of the rigid support strip 9 and the vent channels 12 of the flexible sealing strip 10 in the sealing support components, can form a complete ventilation path to timely remove moisture from inside the curtain wall and prevent internal dampness. The sealing edge 17, the flexible sealing strip 10, the sealing layer 20 in the connecting groove 19, and the rubber strip 13 on the subsequently installed decorative cover 14 will form multiple sealing defenses.

[0030] Finally, the decorative cover 14 is slidably engaged with the connecting groove 19 of the fastener 8 through the limiting edge 18, ensuring that the sealing layer 20 in the connecting groove 19 is in close contact with the limiting edge 18. Then, the adjacent decorative covers 14 are engaged and fixed through the engaging groove 22 by the connector 21, ensuring that the rubber strip 13 on the decorative cover 14 is in contact with the curtain wall body 1, thus completing the overall assembly.

[0031] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
