Fire extinguishing sandwich panel for indoor buildings

Abstract

The invention discloses a fire extinguishing sandwich panel for indoor buildings. The fire extinguishing sandwich panel comprises a first steel plate, a convex edge is formed on the first steel plateand integrally formed with the first steel plate, a bolt cap is arranged on the left side of the convex edge and detachably connected with the convex edge, a bolt column is arranged at the end, penetrating through the first steel plate, of the bolt cap and fixedly connected to the convex edge, and a steel sealing strip is arranged on the outer side of the bolt column. A sandwich panel sealer capable of sealing the joint is arranged on an original sandwich panel and clamps the first steel plate and a second steel plate through clamping plates, the clamping plates are fixed through pressing rods, and a sealing strip seals the first steel plate, a heat insulating plate, a partition plate, an asbestos block and the second steel plate to effectively insulate the contact between the heat insulating plate and the outside, the contact between the partition plate and the outside and the contact between the asbestos block and the outside, so that the influence of high temperature to the heat insulating plate, the partition plate and the asbestos block is reduced, the possibility of burning the sandwich panel is decreased, and potential safety hazards of the buildings are reduced.

Description

technical field [0001] The invention belongs to the technical field of sandwich panels, and in particular relates to a fire-extinguishing sandwich panel for indoor buildings. Background technique [0002] Sandwich panels are composed of two layers of formed metal panels (or other material panels) and a polymer heat insulation core that is directly foamed and cured in the middle of the panels, which is easy to install, lightweight and efficient. The filling system also uses a closed-cell molecular structure, which can prevent condensation of water vapor. [0003] When the original sandwich panels used in indoor buildings encounter a fire, because there are gaps in the joints of the sandwich panels, the joints are prone to burning at high temperatures, causing the sandwich panels to collapse, causing physical damage to the people in the building, and affecting the sandwich panel. The safety of the use of the core board brings potential safety hazards to the building. Conten...
