Sandwich panel with fire protection function and construction wall using the same

Abstract

According to the present invention, a sandwich panel comprises: a pair of exterior panels at a distance away; an insulation material with which a gap between a pair of exterior panels is filled; an upper heat shield plate and a lower heat shield plate manufactured with a material whose melting point is higher than a combustion heat of the insulation material, and inserted to allow the insulation material to cross in a horizontal direction; and a water pipe manufactured with a material which can be melted by the combustion heat of the insulation material inserted into a gap between the upper heat shield plate and the lower heat shield plate. The present invention has the effects of suppressing fire at an early stage by injecting water to an insulation material if an internal insulation material catches fire due to an outbreak of a fire, reducing fire damage by preventing a phenomenon where the insulation material catches fire spreads upwards supplying water without installing a separate water pipe; thus constructing a building more conveniently.

Description

technical field [0001] The present invention relates to a sandwich panel (sandwich panel) filled with heat insulating material between mutually spaced exterior panels (panels) and a building wall using the same. Sandwich panels and building walls with fire-fighting functions. Background technique [0002] Sandwich panels have a short construction period, simple construction, and low price. Compared with existing building materials, they can save construction costs, so they are often used, and they contain heat insulating materials inside, so they have good heat insulation effects, which are 21.5 times better than bricks. , 49 times the good heat insulation effect of concrete has become the most economical assembled building material that can greatly save the maintenance and management costs of buildings. [0003] Not only that, but it has the advantages that there is almost no damage when disassembled, and it can be reused. It can be easily assembled and disassembled by scr...

Problems solved by technology

[0005] In this way, in order to achieve thermal insulation, heat insulation and sound insulation effects, the sandwich panel is composed of a form in which thermal insulation materials such as polystyrene foam (styrofoam) foamed with synthetic resin materials are filled between the outer panels. Made of metal generally does not catch fire, but Styrofoam insulation is a fire-prone material and has the disadvantage of spreading the fire very quickly when a fire does break out

In particular, since the fire on the heat insulating material is covered by the metal exterior panel, even if fire-fighting water is sprayed in the direction of the sandwich panel, the fire of the heat insulating material will not be extinguished easily, and because the heat insulating material Burning is difficult to confirm with the naked eye from the outside, so there is a problem of re-ignition of fire due to residual fire existing in the heat insulating material

[0006] In addition, since existing sandwich panels cannot fill water pipes, there is the inconvenience of having to install additional water pipes in the case of building walls using sandwich panels
