Description

Technical Field

[0001] This utility model relates to the field of steel frame structure technology for buildings, and in particular to a fireproof and waterproof sealing structure for green buildings. Background Technology

[0002] Building sealing structures, as an important component of building envelope systems, are widely used in critical locations such as wall joints, connections between door and window frames and walls, and steel structure nodes. Their performance directly affects the overall fire resistance and waterproofing of the building. In traditional buildings, commonly used sealing structures often consist of a single sealing element (such as rubber strips or sealant) combined with a steel frame structure. While this can achieve basic sealing functions in the short term, many problems will arise over time.

[0003] Regarding the aforementioned technologies, it has been found that the main supporting steel frames used in existing green buildings are mostly hollow or filled with flammable materials such as polystyrene. These materials are prone to melting at high temperatures, releasing toxic gases and posing installation hazards. The joints between the steel frame and the building frame rely solely on bolts or sealant. Under high temperatures, these sealants are prone to aging and carbonization, failing to prevent the spread of flames and smoke and exacerbating fire hazards. Furthermore, traditional building structures often rely on a single sealing layer (such as a single rubber strip or sealant). Rubber strips are prone to aging and cracking due to ultraviolet radiation and rainwater, and uneven sealant application can leave seepage channels. In rainy or high-rise buildings, rainwater under high pressure can easily seep into the interior, corroding steel reinforcement and damaging finishes. Ultimately, traditional sealing structures have extremely high leakage rates after prolonged use. Utility Model Content

[0004] This utility model solves the problems in related technologies and proposes a fireproof and waterproof sealing structure for green buildings.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: A fireproof and waterproof sealing structure for green buildings includes a main steel frame, which includes a frame shell and a filling core. The filling core is fixedly installed in the frame shell. Side sealing seats are integrally formed on both sides of the frame shell. A matching building frame is inserted into the side sealing seat and fixed to the building frame by a locking plug. Two sets of sealing plates are symmetrically installed on the inner side of the building frame, and an inner support assembly for locking the two sets of sealing plates is installed on one side of the building frame.

This ensures that the building frame 3 can be stably installed on both sides of the main steel frame 1. The side sealing seats 2 and the building frame 3 are fixed together by locking plugs 6, ensuring the stability of the connection. Furthermore, the plug-in connection between the side sealing seats 2 and the building frame 3, combined with multiple sets of sealing strips, effectively ensures the sealing between the two, thereby effectively improving the fireproof and waterproof effect at the connection. A sealing plate 4 is installed inside the building frame 3 and locked by the internal support assembly 5, enhancing the sealing effect, preventing rainwater leakage, and improving waterproof performance. The sealing plate 4 can be made of different materials, such as transparent glass, heat-insulating glass, or metal plate, depending on the application scenario.

The side sealing strips 312 are symmetrically arranged on both sides of the trapezoidal cross-section shell 311 and are fixedly connected to the trapezoidal cross-section shell 311. The insertion vertical seat 31 adopts the structure of trapezoidal cross-section shell 311 and side sealing strips 312. The design of the trapezoidal cross-section shell 311 increases the stability of the insertion vertical seat 31, and the side sealing strips 312 can further seal the gap between the insertion vertical seat 31 and the side sealing seat 2, improving waterproof and fireproof performance. A second right-angle card plate 331 for installing the lock plug 6 is fixedly installed on the outer side of both the front frame assembly 32 and the rear frame assembly 33. A second inclined block 332 is also integrally formed on the inner side of the second right-angle card plate 331. The second right-angle plate 331 provides a fixing point for the installation of the lock plug 6. The second inclined block 332 cooperates with the first inclined block 223 to make the lock plug 6 more secure during installation, which enhances the tightness of the connection between the side sealing seat 2 and the building frame 3 and improves the stability of the structure.

The push bolt 53 is threadedly connected to the trapezoidal cross-section shell 311, and the head of the push bolt 53 is rotatably connected to the support bar 51. The inner support assembly 5 pushes the support bar 51 through the push bolt 53, causing the support bar 51 to slide on the trapezoidal cross-section shell 311 via the transverse slide bar 52, thereby locking the sealing plate 4. This structure allows adjustment of the position and pressure of the sealing plate 4 as needed, ensuring the stability and reliability of the sealing effect. Example 2
