Description

Fireproof Insulation Panel

More particularly, the present invention relates to a building panel, and more particularly, to a construction panel in which a core material is disposed on the inside of a shell, and a heat-generating pad filled with a liquid or gel-like material is disposed in the core material, The present invention relates to a fire-resistant insulating panel for preventing fire spread by allowing a liquid or gel-like substance to leak out in a fire to provide a heat-shielding effect.

Generally, a thermal insulation panel for construction is a building material used as inner and outer walls of a building by adhering insulation between an iron plate and an iron plate, and is widely used in construction sites and ships because of its low cost and convenient construction. Glass wool, mineral wool (rock wool), styrofoam, urethane foam, etc., which have high thermal insulation performance, are used as the filler used between the steel plate and the steel plate. In particular, for the fireproof structure, glass wool, mineral wool And so on.

Since it is difficult to secure the fire safety performance of such a thermal insulation panel for a building, a ceramic wool is filled in a joint part of the insulation panels and a joint part is connected by riveting. In this connection method, There is a problem of low applicability. In addition, products produced from flame retardant EPS and flame retardant urethane foam, which have good heat insulation performance and are easy to handle, are heavily burdened by high production costs and construction costs.

In order to solve such a problem, Korean Patent Laid-Open Publication No. 10-2011-0103502 (published on Sep. 21, 2011) discloses a protection panel for a wall, which is installed on an upper part of a panel-type panel for protecting the upper part of the panel When a fire is generated in the building by forming a flow path for supplying fire water along the longitudinal direction on the lid, water is supplied to the internal heat insulating material of the prefabricated panel constituting the wall through the fire water supply flow path, And which can prevent or delay the collapse of the wall.

However, since such a building panel requires a separate facility for supplying water to the inside of the core of the panel, it is expensive, complicates the structure of the building, and if damage occurs to facilities for supplying water in the event of a fire, There is a problem that water can not be supplied to the panels and fire resistance performance can not be obtained.

Published Patent No. 10-2011-0103502 (published on September 21, 2011) Registration No. 10-0720975 (registered on May 16, 2007) Registration No. 10-0232800 (registered on September, 1999)

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a fire-resistant insulating panel according to the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 show a fire-resistant insulating panel according to an embodiment of the present invention. The fire-resistant insulating panel of this embodiment comprises two outer shells 10 arranged in parallel to each other at a certain distance, (20) disposed between the core (10) and a heat pad (30) provided inside the core (20).

The outside sheathing 10 is made of a hard material such as a metal such as steel or a heat-resistant resin, and functions as a support for the heat insulating panel. The surface of the outside sheathing 10 may be coated with a fire-resistant paint or a heat-expandable paint. The outer sheath 10 may be entirely flat, but it may be a zigzag bent surface.

The core (20) is filled between the shell plates (10) to provide heat insulation performance. The core 20 may be formed by using a material used in conventional insulation panels such as glass wool, mineral wool (rock wool), styrofoam, urethane foam, flame retardant EPS, and flame retardant urethane foam. Since the core 20 is made of a material such as fiber or foam that is easily deformable, it is uniformly adhered to the surface of the heat shield pad 30 while being deformed according to the shape of the heat shield pad 30 included therein.

The heat shield pad 30 is buried in the center portion of the core member 20 and retains the fluid therein to increase the heat insulating performance. In case of fire, the fluid flows out into the core member 20 while flowing out, And the heat insulating panel is cooled to perform the heat shielding function.

In this embodiment, the heat shield pad 30 comprises a sheet 31 made of a resin melted at a temperature higher than a predetermined temperature in a fire and having a plurality of pockets 32 arranged in a lattice form, And a cooling fluid (33) on a liquid or gel-like gel to be filled in the cooling fluid (33).

The pocket 32 of the heat shield pad 30 may have various shapes such as a hexahedron or a polygonal or spherical shape, a dome shape, a cylindrical shape, a polygonal shape, and the like. Here, the lattice form includes not only a form in which the rows and columns are arranged in the same line but also a form in which the odd columns and the even columns are arranged in zigzags. Of course, the pockets 32 may be arranged in various arrangements other than such a lattice arrangement structure.

The pockets 32 are preferably spaced apart from one another to prevent the cooling fluid 33 of adjacent pockets 32 from leaking out when one pocket 32 ruptures due to other factors than fire .

The seat 31 of the heat shield pad 30 is made of resin such as polystyrene or polypropylene which can be melted by heat at a high temperature in the event of a fire. The sheet 31 may be a single sheet. However, the first sheet 31a may have a plurality of pockets 32 convexly formed in a dome shape, as in this embodiment, And a second sheet 31b having a plurality of pockets 32 convex in the form of a dome formed at positions corresponding to the pockets 32. [ At this time, the pockets 32 of the first sheet 31a and the pockets 32 of the second sheet 31b are brought into contact with each other to form pockets 32 having a spherical shape, a dome shape, a cylindrical shape or a polygonal shape .

Alternatively, as shown in FIG. 6, the sheet 31 may include a first sheet 31a which is entirely planar, and a plurality of pockets 32 which are convexly formed in a dome shape at regular intervals The second sheet 31b may be stacked.

The cooling fluid 33 filled in the pocket 32 of the heating pad 30 is made of a liquid such as water or a cold gel so that when the pocket 32 is melted by fire, Flows into the core (20) to lower the temperature and provide a heat shielding effect. The cooling fluid 33 is preferably composed of an antifreeze as a whole or a composition containing a part of an antifreeze in a liquid or a gel so as to prevent freezing in winter. As the antifreeze, for example, ethylene glycol may be used.

In order to fill the plurality of pockets 32 of the seat 31 with the cooling fluid 33, it is preferable that a fluid passage 34 connecting the plurality of pockets 32 be formed as shown in FIG. 7 . Therefore, when a cooling fluid 33 is injected into a pocket 32, the cooling fluid 33 flows through the fluid passage 34, so that the cooling fluid 33 can be filled in all the pockets 32.

The heat insulating panel of the present invention improves the heat insulating performance by preventing the sheet 31 and the cooling fluid 33 of the heat shield pad 30 from interfering with heat transfer at the normal time, The temperature of the entire adiabatic panel is greatly lowered and the heat is shut off, so that deformation and collapse of the adiabatic panel can be suppressed and fire spreading can be prevented.

8, the heat shield pad 30 is provided between the sheathing pad 10 and the core material 20, as shown in the second embodiment of FIG. 8, ) May be installed. In this case, the heat shield pad 30 may be provided on both sides of both the outer shell 10 and the core 20, but may be provided only on one side of the outer shell 10 and the core 20 .

The construction and operation of the heat shield pad 30 are the same as or similar to those of the heat shield pad 30 of the first embodiment described above, and therefore, detailed description thereof will be omitted.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the present invention as defined by the appended claims. And it is to be understood that such modified embodiments belong to the scope of protection of the present invention defined by the appended claims.
