Description

Automatic Fire Extinguisher for Sandwich Panel Installation}

The present invention relates to an automatic fire extinguisher for installing a sandwich panel, and more particularly, it is embedded in one side of the sandwich panel, and explodes by flame when a fire occurs, and expands the extinguishing powder provided inside by expansion of air according to the explosion. It is related to an automatic fire extinguisher for installing a sandwich panel that scatters and diffuses so that the fire can be extinguished.

In general, a sandwich panel (composite panel) is a building material that is widely used in the interior and exterior walls of a building by inserting a core material, which is an insulation material, between the panel board (steel sheet, etc.) and the panel board.

These sandwich panels have low thermal conductivity, low cost, and are widely used as exterior walls, especially in buildings such as factories and warehouses because of the convenience of construction due to the light weight of the core material.

At this time, as the core material used between the panel board and the panel board, a material with excellent insulation is required. In general, inorganic fillers such as glass wool and mineral wool (rock wool) and organic fillers such as styrofoam and urethane foam are used. .

Among them, composite panels using inorganic core materials such as glass wool and mineral wool (rock wool) are also excellent in fire resistance, so large-scale buildings use them.

On the other hand, sandwich panels using organic fillers of general EPS or urethane foam are inexpensive and have excellent mechanical, thermal and performance such as insulation, workability, and non-absorption, but because of their flammability, which is very vulnerable to fire, sandwich panels using them are in principle buildings. Is prohibited from being used in.

In order to solve these shortcomings, panel boards using flame-retardant EPS and flame-retardant urethane foam that have enhanced the flame-retardant performance of the core material are used, but the fire-resistance performance is significantly lower than that of glass wool and mineral wool (rock wool), so there is still a risk of fire. Remains.

That is, once a fire occurs and the core material is ignited, fire extinguishing is almost impossible because fire extinguishing water does not penetrate even if fire extinguishing facilities such as sprinklers operate due to a panel board such as a steel plate surrounding the outside.

Numerous pores are developed in the core material, and a large amount of toxic gas is generated as incomplete combustion continues by oxygen in the air stored in the pores.

Therefore, in the case of a sandwich panel fire using these organic core materials, fire extinguishing equipment already installed in the building such as sprinklers is operated, or even if water is sprayed from a fire engine, fire extinguishing water cannot penetrate due to the steel plate attached to the outside of the panel board, and the fire is burned out. Most of them are, and this causes a large amount of personal damage, large-scale property damage, and environmental damage, which is a serious social problem.

In this way, since it is difficult to secure fire safety performance in a building using sandwich panels, ceramic wool is filled in the joints of the sandwich panels and the joints are constructed and connected by a rivet fastening method to compensate for this. The method (joint) has problems with low field applicability, such as difficulty in securing construction quality and high construction cost.

Therefore, in order to prevent the fire from spreading from the sandwich panel to the adjacent sandwich panel in the event of a fire of the sandwich panel, the fire extinguishing water can penetrate, or a buffer space in which a non-combustible composite panel is inserted between the sandwich panel and the sandwich panel is provided. It is necessary to develop a method that can fundamentally secure fire safety.
