Description

Technical Field

[0001] This utility model relates to the field of building exterior wall technology, specifically to a foam fireproof structure for building exterior walls. Background Technology

[0002] Foam fireproofing technology for building exterior walls is an important safety measure developed to address the flammability defects of organic insulation materials. Polystyrene (EPS / XPS), polyurethane, and other foam materials are widely used due to their lightweight and excellent insulation properties, but their fire resistance rating is generally lower than B2. They are prone to melting and dripping when exposed to open flames, releasing toxic gases and causing numerous multi-level fires in high-rise buildings.

[0003] For example, the utility model patent with announcement number CN201649497U discloses a fireproof isolation strip board for building exterior walls, characterized in that: the board mainly includes a polyurethane insulation layer, a fireproof insulation layer, a decorative surface layer, and a cement-based backing layer; the cement-based backing layer is connected to the polyurethane insulation layer, and the polyurethane insulation layer is connected to the decorative surface layer; a fireproof insulation layer is provided inside the polyurethane insulation layer.

[0004] However, this utility model prevents the spread of fire by setting a fireproof and heat-insulating layer, but it does not have a fire extinguishing function, which means that the flames cannot be extinguished in time when a fire occurs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a foam fireproof structure for building exterior walls, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foam fireproof structure for building exterior walls, comprising a wall, a leveling layer, foam boards, a grid mortar layer, and a waterproof decorative layer. The structure is characterized by a storage box disposed between two adjacent foam board layers along the height direction. The thickness of the storage box is the same as the thickness of the foam board. The storage box stores a flowable fire extinguishing medium, including dry powder extinguishing agent or fire extinguishing sand. An opening is provided at the bottom of the storage box, and a guide pipe is connected to the opening. The guide pipe is placed within the foam board. Multiple through holes are provided along the height direction on the side wall of the guide pipe. A sealing plate is installed in each through hole. When a fire occurs, the sealing plate softens and deforms due to high-temperature combustion. After deformation, the sealing plate detaches from the through hole under the push of the fire extinguishing medium, allowing the fire extinguishing medium to flow out through the through hole.

[0007] Preferably, the bottom of the storage box includes multiple bucket-shaped structures, and the openings are multiple and respectively located at the lowest point of each bucket-shaped structure.

[0008] Preferably, the through hole is conical, and the end with a large diameter is directed to the inside of the flow guide pipe, and the plugging plate is shaped to match the through hole.

[0009] Preferably, the storage box is provided with a plurality of fixing pieces.

[0010] Preferably, the upper wall of the storage box is provided with a filling hole. Beneficial effects

[0011] The building outer wall foam fireproof structure has the following beneficial effects: the storage box arranged between the two adjacent foam plates in the height direction can form a fireproof isolation belt in the height direction, so that the spread of fire is prevented, the fire extinguishing medium in the storage box can be automatically discharged when a fire occurs, and the foam plates are extinguished by the fire extinguishing medium; the multiple openings and the multiple through holes on the flow guide pipe can increase the discharge points of the fire extinguishing medium, so that timely fire extinguishing is achieved, and the spread speed of the fire is further reduced.

[0017] The technical solutions in the embodiments of the building outer wall foam fireproof structure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the building outer wall foam fireproof structure.

[0018] Please refer to Figures 1-4The utility model provides a technical scheme: a building outer wall foam fireproof structure, including wall body 1, leveling layer 2, foam board 3, grid mortar layer 4, waterproof decorative layer 5, be provided with storage box 6 between two foam boards 3 of adjacent height direction, can form the fireproof isolation zone of height direction through storage box 6, the thickness of storage box 6 is same with foam board 3 thickness, the extinguishing medium that can flow is stored in storage box 6, when the fire happens, extinguishing medium can flow out through the opening 7 of storage box 6 bottom, and the foam board 3 that burns is extinguished through the extinguishing medium that flows out, and extinguishing medium includes but is not limited to dry powder extinguishing agent, fire extinguishing sand, and opening 7 can be blocked by foam board 3, a plurality of fixed sheets 11 are connected on storage box 6, and storage box 6 is fixed on wall body 1 through fixed sheet 11, and the upper wall of storage box 6 is provided with filling hole 12, and extinguishing medium can be injected into storage box 6 through filling hole 12.

[0019] Further, the bottom of the storage box 6 includes a plurality of bucket-shaped structures, and the openings 7 are a plurality of openings respectively arranged at the lowest points of each bucket-shaped structure, so that the discharge points of the extinguishing medium are more dispersed, and the extinguishing medium in the storage box 6 can be maximally discharged through the bucket-shaped structures.

[0020] As an embodiment of the utility model, the plurality of openings 7 are blocked by the fixed foam board 3, and when the foam board 3 burns, the openings 7 are opened, so that the extinguishing medium is automatically discharged.
