In general, the internal space of a building is divided into a plurality of spaces by a floor and a wall, and a through hole through which various pipes or ducts can pass is formed in a frame of a building such as a floor or wall. The through hole of the building frame is formed to have a size larger than the width of the pipe or duct so that the pipe or duct can pass through the through hole even if there is a design error when installing the pipe or duct.

However, as the through hole of the building frame is formed with a size larger than the width of the pipe or duct, a gap is inevitably created between the building frame and the pipe or duct when the pipe or duct is installed. There is a problem of spreading the damage caused by fire by becoming a passage.

In order to solve this problem, it is currently legally compulsory to block the penetration hole of the building frame with fire-resistant materials, which can spread fire in the event of a fire.

As shown in the drawing, the fire-resistant foam unit 100 according to an embodiment of the present invention includes a fire-resistant foam material 110 that can expand by heat, and a fire-resistance mesh that is coupled to one surface of the fire-resistant foam material 110 ( 120). Such a fireproof foam unit 100 shields the through hole formed in the building frame such as the floor or wall of the building so that the passage member having a passage formed therein can pass, so that flames or smoke spread to the through hole when a fire occurs. Can be prevented.

The passage member may be various installed to pass through a through hole formed in a structure frame, such as a pipe or a duct, an electric cable, or a communication cable. In this embodiment, for example, the fireproof foam unit 100 shields the through hole 71 formed in the wall 70 of the building so that the passage member 80 in the form of a duct can pass.

The fireproof foaming material 110 is formed in a flat plate shape that can cover the through hole 71, and is made of a thermally expandable material that can expand by heat. When a fire occurs, the fireproof foam 110 expands by receiving heat, thereby effectively shielding the gap between the wall 70 and the passage member 80 and the through hole 71. The refractory foaming material 110 may be manufactured in a flat plate shape by extruding an expanded graphite or a refractory foaming mixture in which various heat-expandable materials that can be expanded by heat are extruded.

The fireproof net 120 has a plurality of through holes 121 and is coupled to the fireproof foam 110.

The fireproof foaming material unit 100 includes a fixing member 220 such that one surface of the fireproof foaming material 110 to which the fireproof mesh 120 is coupled faces the outside and the other surface of the fireproof foam 110 faces the wall 70. It is fixed to the wall 70 through. In the event of a fire, since heat can be smoothly transferred to the fireproof foam material 110 through the through hole 121 of the fireproof mesh body 120, the fireproof foam material 110 rapidly expands and the wall 70 and the passage member The gap between the 80 and the through hole 71 can be quickly shielded. The fireproof mesh 120 is made of a material that is not easily damaged by heat when a fire occurs, so that even if a fire occurs, it can be maintained fixed to the wall 70 by the fixing member 220, and the fireproof foam 110 It may support the fireproof foam 110 so as not to be separated from the wall 70 during the expansion.

In this way, in the fireproof foaming material unit 100 according to an embodiment of the present invention, the fireproof mesh 120 having a simple structure is fixed to the wall 70 to support the fireproof foaming material 110 that expands by heat. . Therefore, in the event of a fire, the fireproof foam material 110 can expand while maintaining the state covered with the through hole 71 of the wall 70, and propagation of flame or smoke through the through hole 71 of the wall 70 Can be stably blocked. In addition, manufacturing cost is inexpensive and workability is excellent.

The fire-resistant foam material 110 and the fire-resistant mesh body 120 of the fire-resistant foam material unit 100 may be bonded to each other by pressing. The refractory foaming material 110 has a soft property that can be deformed in a high temperature environment. When the fire-resistance mesh body 120 is pressed against one side of the fire-resistance foam material 110 while the fire-resistant foam material 110 is soft, at least a portion of the fire-resistance mesh body 120 penetrates into the fire-resistant foam material 110 and fires fire-foaming. It is buried in the ashes 110. Therefore, it is possible to combine the fireproof foam material 110 and the fireproof mesh 120 without using a separate adhesive or fixing member.

As shown in FIGS. 3 and 4, the fireproof mesh 120 is at least partially buried in the fireproof foam 110 so that the fireproof foaming material 110 and the fireproof mesh 120 can maintain a stable bonded state. It is good to be press-coupled to one side of the ash 110. More preferably, the depth (D) of the fireproof mesh 120 is buried in the fireproof foam material 110 is greater than the height (H) that the fireproof mesh 120 protrudes from one surface of the fireproof foam material 110 It is advantageous for a stable coupling between (110) and the fireproof net (120).

The fireproof foaming material unit 100 can be cut without difficulty by tools such as scissors, the fireproof foaming material 110 and the fireproof mesh 120, a passage member installed in the through hole 71 of the wall 70 It can be used after being cut according to the shape of (80). For example, as shown in FIG. 5, the fireproof foam unit 100 may be cut by a tool 50 such as scissors such that a hole through which the passage member 80 can pass is formed in the center thereof.

In this way, the fireproof foaming material unit 100 according to an embodiment of the present invention can be cut into various shapes and used, so it can be used universally to shield through holes in which various types of passage members are installed, and construction is convenient. Do.

It is preferable that the thickness (T) of the fireproof mesh 120 is 0.1 ~ 0.6mm so that the fireproof foam unit 100 can be cut by a tool 50 such as scissors. When the thickness (T) of the fireproof mesh 120 is less than 0.1mm, the fireproof mesh 120 has a weak support for supporting the fireproof foaming material 110, and thus it is difficult for the fireproof mesh 120 to exhibit a smooth function. On the other hand, when the thickness (T) of the fireproof mesh 120 exceeds 0.6mm, the fireproof mesh 120 is difficult to be cut by tools such as scissors, and there is a problem that price competitiveness is lowered.
