Abstract
Description
Technical Field
[0001] This utility model relates to the field of building partition technology, specifically to a prefabricated fireproof partition system. Background Technology
[0002] Fire-resistant partitions, as important functional building components, play a crucial role in ensuring building fire safety. Traditional fire-resistant partitions mainly rely on heavy reinforced concrete walls or double-layer gypsum board combined with ordinary light steel keel systems. The former has a long construction period, involves a lot of wet work, and is difficult to dismantle and modify later, making it unsuitable for the needs of modern prefabricated construction; the latter, while offering some ease of installation, has limited load-bearing capacity, insufficient overall stability and impact resistance, and the simple cavity design of ordinary light steel keel systems makes it difficult to effectively isolate the spread of fire and sound transmission while ensuring lightweight construction, failing to meet high standards of fire resistance and sound insulation performance, especially in large-span spaces or high-fire-rating areas where there are limitations.
[0003] With the rapid development of prefabricated buildings, the market urgently needs a lightweight partition wall system that combines efficient installation with excellent fire resistance and sound insulation. Some existing prefabricated lightweight partition wall systems attempt to improve performance by filling with various materials or reinforcing joints, but these typically suffer from problems such as poor overall structural stability, uneven fire resistance and sound insulation, complex installation procedures, and insufficiently rigorous joint treatment. Therefore, there is an urgent need to develop an innovative prefabricated fireproof partition wall system with a more rational structural design, efficient fire resistance and sound insulation filling, robust and reliable connections, and convenient installation.

[0029] In practical application, the prefabricated fireproof partition wall system according to this utility model is implemented as follows: This prefabricated fireproof partition wall system was implemented in the interior space partitioning project of an office building. The specific steps are as follows: I. Installation of the keel frame; Multiple parallel, unidirectional keel structures are installed between the opposing side walls of the building structure, while multiple vertical, non-unidirectional keel structures are installed between the top wall and the floor wall. The unidirectional keel structures utilize a three-cavity W-shaped cross-section, with its central cavity extending in the same direction as the cavities of the side panels. The non-unidirectional keel structures utilize a four-cavity S-shaped cross-section, with the two central cavities and two panel cavities distributed alternately in opposite directions. A through-core keel is vertically installed between adjacent non-unidirectional keels to enhance overall integrity, and the joints between the through-core keel and the non-unidirectional keel are secured with mechanical fasteners.

In the S-shaped counter-directional keel, fireproof and sound-insulating core panels are installed simultaneously in the two central cavities. After the two panel cavities are filled with rock wool, fireproof and sound-insulating panels are installed. All fireproof and sound-insulating panels are fixed to the keel edges and filling layers using connectors, and the panel seams are staggered and overlapped.
[0031] III. Sealing and Joint Treatment; Elastic sound insulation pads are embedded in the stepped sealing grooves on the side and top walls of the keel. Flexible sealing material is filled at the joints between the wall and the fireproof sound insulation board, and reinforced joint tape is used for coverage. The opposing keels at the door and window openings are connected to the door frame reinforcement components to improve local strength. The perpendicularly intersecting opposing and co-orienting keels are connected by insert-type connecting plates and fasteners.
[0032] IV. Finishing layer construction; Inorganic decorative panels are fully laid on the outside of the second fireproof and soundproof panel, using a staggered bonding process to ensure a smooth finish. Professional testing has shown that this system meets the fire resistance and sound insulation requirements of national building fire protection codes, and its structural stability and impact resistance also comply with engineering standards.
[0033] In summary, by employing the above-mentioned technical solution of this utility model, and using a three-cavity W-shaped co-directional keel with cavities arranged in the same direction and a four-cavity S-shaped anti-directional keel with cavities arranged in opposite directions, combined with a through-core keel to enhance the overall structural integrity, the system skeleton possesses excellent impact resistance and load distribution capacity. By layering rock wool and inner and outer fireproof and sound insulation boards within the cavities of various keels, multiple fireproof and sound insulation barriers are formed. Combined with sound insulation pads, stepped sealing grooves, and joint treatment using sealant, high standards of fireproof integrity, heat insulation, and sound insulation and noise reduction performance are achieved. At the same time, standardized bolts, self-tapping screws, and snap-fit connections are used between components to achieve efficient and convenient assembly construction. The staggered installation of the decorative layer ensures the flatness of the wall surface, ultimately forming a prefabricated fireproof partition wall system with high functional integration, superior performance, and reliable installation.
