Description

Fire resistance panel {FIRE RESISTANCE PANEL}

The present invention relates to a fireproof panel, and more specifically, to a fireproof panel installed in the interior space of a building to partition the space.

In various buildings, partition walls in the form of several panels assembled are installed to partition internal spaces, and fireproof panels are sometimes used as such panels in case a fire breaks out. A fireproof panel has a sandwich structure in which a core material is located between two thin skins made of metal bent into a predetermined shape, and the core material is made of a fireproof material such as glass wool, polyurethane foam, etc.

An example of the fire-resistant panel is disclosed in Patent Registration No. 10-2027382 (fire-resistant sandwich panel).

In the fireproof panel of the above registered patent publication, a protruding fastening part and a retracting fastening part are formed at both ends of the panel in the horizontal direction. The protruding binding portion is provided in a form in which the skin protrudes outward from the core material, and the retracting binding portion is provided in a form in which the skin is recessed toward the core material. When the protruding joint of one of two adjacent fireproof panels is inserted into the retractable joint of the other panel, the two fireproof panels are coupled to each other.

In addition, in the fireproof panel of the above registered patent publication, the protruding joint portion is made of metal with a coefficient of thermal expansion that exceeds a preset standard value. Therefore, when a fire occurs, the protruding joint thermally expands and adheres to the incoming joint, which causes smoke to spread from one of the two spaces divided by the fireproof panels to the other space through the joint between the fireproof panels. is prevented.

Registered Patent Publication No. 10-2027382 (Fire-resistant sandwich panel)

The above registered patent publication secures airtightness at the joint area between fireproof panels through deformation of the protruding joint. However, it is not easy to manufacture only the protruding joint portion to have greater thermal expansion than other parts of the skin.

In addition, in the event of a fire, the entire skin is deformed by heat, and the core material made of flame-retardant materials (glass wool, polyurethane foam, etc.) has low rigidity enough to deform when pressed by hand, preventing deformation of the skin due to heat. However, there is no guarantee that the protruding coupling portion and the retracting coupling portion will be deformed as intended in the above registered patent publication, and there is more room for deformation into unexpected forms.

Therefore, it is difficult to ensure airtightness at the joint area between the fireproof panels by leaving the deformation of the skin as is, as in the above registered patent publication. Therefore, the present invention combines the fireproof panels in a way to prevent the deformation of the skin itself. We aim to provide technology that can secure confidentiality in this area.

In addition, the above fire-resistant panels 100, 200, and 300 are provided to prevent smoke from a fire from spreading from one of the two partitioned spaces to the other space by ensuring airtightness at the joints where they are joined together. there is.

Below, the direction from the floor of the upper internal space to the ceiling is the vertical direction (the direction coming from the ground in the drawings), one direction parallel to the floor is the horizontal direction (the left-right direction in the drawings), and the remaining direction is the thickness direction. (Up and down in the drawings), the fireproof panels 100, 200, and 300 according to the present invention will be described for each embodiment. And for ease of understanding, the first ends (134, 234, 334) and second ends (136, 236, 336) of the skins (130, 230, 330) are shown in the drawings larger than they actually are.

<First Embodiment>

The fireproof panel 100 according to this embodiment includes a core material 110 and a pair of skins 130, as shown in FIG. 1.

The core material 110 is made of a fire-resistant material such as glass wool, polyurethane foam, etc. And the core material 110 has a pair of surfaces 112 spaced apart in the thickness direction, and a first side 114 and a second side 116 connecting the pair of surfaces 112 spaced apart in the horizontal direction. ) has. The first side 114 and the second side 116 have the same cross-section and extend in the vertical direction.

The pair of skins 130 is made of a thin metal material that can be bent, and the shape of the pair of skins 130 is symmetrical with respect to the center line of the core material 110 extending in the horizontal direction. And each skin 130 is connected to a central portion 132 covering the upper surface 112 and both horizontal ends of the central portion 132 to the first side 114 and the second side 116, respectively. It has a first end 134 and a second end 136 located thereon. The first end 134 and the second end 136 have the same cross-section and extend in the longitudinal direction.

The first end 134 has a primary bent portion 134a bent in the thickness direction at one end of the central portion 132. In addition, the first end 134 has a second bending portion 134b bent away from the core material 110 at the first bending portion 134a, and a second bending portion 134b bent again in the thickness direction. It also has a third bending portion 134c and a fourth bending portion 134d bent from the third bending portion 134c toward the core material 110.

A deformation prevention member 150 having an “L” shaped cross section and extending in the longitudinal direction is inserted into the first end 134. And when this insertion is made, the portion of the deformation prevention member 150 extending in the thickness direction is located in the gap between the first bent portion 134a and the first side 114, and the deformation extending in the transverse direction is performed. The portion of the prevention member 150 is located in a gap surrounded by the second bending portion 134b, the third bending portion 134c, and the fourth bending portion 134d. The deformation prevention member 150 is made of a metal material thicker than the skin 130.

The second end 136 has first to fourth corresponding bending portions 136a, 136b, 136c, and 136d. The first corresponding bending portion 136a is bent in the thickness direction at the opposite end of the central portion 132 and is formed in a shape that can come into contact with the first bending portion 134a. The secondary corresponding bending portion 136b is a portion bent from the primary corresponding bending portion 136a toward the core material 110, and is formed in a shape that can come into contact with the secondary bending portion 134b. The third corresponding bending portion 136c is a portion bent in the thickness direction from the second corresponding bending portion 136b, and is formed in a shape that can come into contact with the third corresponding bending portion 134c. The fourth corresponding bending portion 136d is a portion bent in a direction away from the core material 110 in the third corresponding bending portion 136c, and is formed in a shape that can come into contact with the fourth corresponding bending portion 134d.

At the joining site of two adjacent fire-resistant panels 100, the first end 134 of one fire-resistant panel 100 and the second end 136 of the other fire-resistant panel 100 come into contact. That is, the first to fourth bending portions 134a, 134b, 134c, and 134d of the first end 134 of one fireproof panel 100 are the second end 136 of the other fireproof panel 100. They come into face-to-face contact with the first to fourth corresponding bending portions 136a, 136b, 136c, and 136d, respectively. In this embodiment, even if a fire occurs, thermal deformation of the first end 134 and the second end 136 is prevented and airtightness is guaranteed at the above joint area. The reason is explained as follows.

First, since a deformation prevention member 150 with high rigidity is provided at the first end 134 of one fireproof panel 100, each of the first to fourth bending parts 134a, 134b, 134c, and 134d is individually Heat deformation is prevented. In addition, because the second end 136 is bent several times in the thickness direction and the longitudinal direction due to the “L” shaped cross section of the deformation prevention member 150, the second end 136 of the remaining fireproof panel 100 also has 1 Individual thermal deformation of each of the first to fourth corresponding bending parts 136a, 136b, 136c, and 136d is prevented. Due to this technical principle, in this embodiment, airtightness can be guaranteed at the joint site between the two fireproof panels 100.

Meanwhile, in the remaining fireproof panel 100, there is room for thermal deformation of the first end 134 or the second end 136 while maintaining its shape, and it is necessary to prevent such integral thermal deformation. For this purpose, a plurality of countersunk head bolts 170 and intervening members 172 and 174 are used in this embodiment.

The intervening members 172 and 174 are inserted into the second insertion groove 116a provided on the second side 116 of the core material 110. The second insertion groove 116a is located between the second ends 136 of the pair of skins 130 and extends in the vertical direction. The bolts 170 are arranged along the vertical direction, penetrate the fourth corresponding bending portion 136d and the core material 110 in the thickness direction, and are firmly attached to the intervening members 172 and 174 in the second insertion groove 116a. is concluded.

Since the core material 110 has a soft property, even if the bolts 170 penetrate the core material 110, the bolts 170 cannot be firmly fastened by the core material 110. Therefore, in this embodiment, the bolts 170 are firmly fastened through the intervening members 172 and 174.

When the above bolts 170 and intervening members 172 and 174 are used, the fourth corresponding bending portion 136d cannot move toward the core material 110, so the second end 136 of the remaining fireproof panel 100 ) cannot undergo integral heat deformation that maintains its shape. And because the 4th bending portion 134d is blocked by the 4th corresponding bending portion 136d, the first end 134 maintains its shape in any fireproof panel 100 and is formed with the core material along with the deformation prevention member 150. It becomes impossible to undergo thermal deformation that bends toward (110).

Meanwhile, the second insertion groove 116a may be sized to accommodate only a portion of the intervening members 172 and 174 and the remaining portion protrudes in the horizontal direction. In this case, a first insertion groove 114a is formed on the first side 114 of the core material 110 to accommodate the remaining portions of the intervening members 172 and 174.

As the intervening members 172 and 174, square pipes 174 made of metal may be used. Here, each pipe 174 refers to a structure previously installed in the interior space above to extend from the floor to the ceiling of the interior space of the building for the structural stability of the building.

When there is no square pipe 174 in the internal space of the building or when several fireproof panels 100 are to be installed between each pipe 174, a fireproof member 172a and a metal channel 172b are included. An intervening member 172 may be used. The fireproof member 172a may be the same as the core material 110. In this case, since the fireproof member 172a cannot firmly support the bolts 170, a metal channel 172b is also used. . The channel 172b is provided to cover at least the surfaces to which the bolts 170 are fastened among the outer surfaces of the fireproof member 172a. Figure 1 illustrates a channel 172b with a “ㄷ” shaped cross-section.

< Second Embodiment >

Below, the fireproof panel 200 according to the second embodiment of the present invention will be described with reference to FIG. 2, focusing on parts that are different from the first embodiment.

In this embodiment, the first end 234 of the skin 230 has a primary bent portion 234a bent in the thickness direction at one end of the central portion 232. In addition, the first end 234 has a secondary bending area 234b bent from the primary bending area 234a toward the core material 210, and a tertiary bending area bent again in the thickness direction at the secondary bending area 234b. It also has a bending portion 234c.

A deformation prevention member 250 having a “Z” shaped cross section and extending in the longitudinal direction is inserted into the first end 234. When this insertion is made, the deformation prevention member 250 is located in the gap between the first to third bending portions 234a, 234b, and 234c and the first side 214.

The second end 236 has first to third corresponding bending portions 236a, 236b, and 236c. The first corresponding bending portion 236a is bent in the thickness direction at the opposite end of the central portion 232 and is formed in a shape that can come into contact with the first bending portion 234a. The secondary corresponding bending portion 236b is a portion bent away from the core material 210 from the primary corresponding bending portion 236a, and is formed in a shape that can come into contact with the secondary bending portion 234b. The third corresponding bending portion 236c is a portion bent from the second corresponding bending portion 236b toward the core material 210 so as to overlap the second corresponding bending portion 236b. Therefore, the skin 230 forms two layers at the second and third corresponding bending areas (236b, 236c).

At the joining site of two adjacent fire-resistant panels 200, the first end 234 of one fire-resistant panel 200 and the second end 236 of the other fire-resistant panel 200 come into contact. At this time, which The first and second bending parts (234a, 234b) of the first end (234) of one fireproof panel (200) are the corresponding first and second bending parts of the second end (236) of the other fireproof panel (200). They come into face-to-face contact with (236a, 236b), respectively. Also, in this embodiment, as in the first embodiment, even if a fire occurs, thermal deformation of the first end 234 and the second end 236 is prevented, and airtightness at the above joint area is guaranteed. The reason is explained. It is as follows.

First, since a deformation prevention member 250 with high rigidity is provided at the first end 234 of one fireproof panel 200, individual thermal deformation of each of the first to third bending areas 234a, 234b, and 234c is prevented. This is prevented. In addition, because the second end 236 is bent several times in the thickness direction and the longitudinal direction due to the “Z” shaped cross section of the deformation prevention member 250, the second end 236 of the remaining fireproof panel 200 also has 1 Individual thermal deformation of each of the first to third corresponding bending portions 236a, 236b, and 236c is prevented. Due to this technical principle, in this embodiment, airtightness can be guaranteed at the joint area between the two fireproof panels 200.

Meanwhile, in this embodiment, as in the first embodiment, a plurality of bolts are used to prevent integral thermal deformation of the first end 234 or the second end 236 at the joint area of the two fireproof panels 200. (270) and intervening members (272, 274) are used.

The intervening members 272 and 274 and the first and second insertion grooves 214a and 216a are the same as the intervening members 172 and 174 and the first and second insertion grooves 114a and 116a of the first embodiment. The bolts 270 are arranged along the longitudinal direction, penetrate the second and third corresponding bending parts (236b, 236c) and the core material 210 in the thickness direction, and insert the intervening members 272, 274) is firmly fastened.

When the above bolts 270 and intervening members 272 and 274 are used, the second and third corresponding bending parts 236b and 236c cannot move toward the core material 210, so that the remaining fireproof panel 200 The second end portion 236 cannot undergo integral thermal deformation while maintaining its shape. And since the secondary bending portion 234b is blocked by the secondary corresponding bending portion 236b, the first end 234 maintains its shape in any one fireproof panel 200 and is formed with the core material along with the deformation prevention member 250. It becomes impossible to undergo thermal deformation that bends toward (210).

<Third Embodiment>

Below, the fireproof panel 300 according to the third embodiment of the present invention will be described with reference to FIG. 3, focusing on parts that are different from the first embodiment.

In this embodiment, the first end 334 of the skin 330 has a primary bent portion 334a bent in the thickness direction at one end of the central portion 332. In addition, the first end 334 has a secondary bending area 334b bent from the primary bending area 334a toward the core material 310, and a tertiary bending area bent again in the thickness direction at the secondary bending area 334b. It also has a bent portion 334c.

A deformation prevention member 350 having a “ㄷ” shaped cross section and extending in the vertical direction is inserted into this first end 334. When this insertion is made, among the parts of the deformation prevention member 350, one part extending in the horizontal direction is located in the space surrounded by the central part 332 and the first and second bending parts 334a and 334b, and has a thickness of The portion extending in this direction is located between the third bending portion 334c and the first side 314.

The second end 336 has first to third corresponding bending portions 336a, 336b, and 336c. The first corresponding bending portion 336a is bent in the thickness direction at the opposite end of the central portion 332 and is formed in a shape that can come into contact with the first bending portion 334a. The secondary corresponding bending portion 336b is a portion bent away from the core material 310 from the primary corresponding bending portion 336a, and is formed in a shape that can come into contact with the secondary bending portion 334b. The third corresponding bending portion 336c is a portion bent in the thickness direction again from the second corresponding bending portion 336b, and is formed in a shape that can come into contact with the third corresponding bending portion 334c.

At the joining site of two adjacent fire-resistant panels 300, the first end 334 of one fire-resistant panel 300 and the second end 336 of the other fire-resistant panel 300 come into contact. At this time, which The first to third bending portions 334a, 334b, and 334c of the first end 334 of one fireproof panel 300 are the first to third bending portions 334a, 334b, and 334c of the second end 336 of the other fireproof panel 300. They are in face-to-face contact with the vehicle-adaptive bending portions 336a, 336b, and 336c, respectively. Also, in this embodiment, as in the first embodiment, even if a fire occurs, thermal deformation of the first end 334 and the second end 336 is prevented, and airtightness at the above joint area is guaranteed. The reason is explained. It is as follows.

First, since a deformation prevention member 350 with high rigidity is provided at the first end 334 of one fireproof panel 300, individual thermal deformation of each of the first to third bending portions 234a, 334b, and 334c occurs. This is prevented. In addition, because the third end 336 is bent several times in the thickness direction and the longitudinal direction due to the "ㄷ" shaped cross section of the deformation prevention member 350, the second end 336 of the remaining fireproof panel 300 also has 1 Individual thermal deformation of each of the first to third corresponding bending portions 336a, 336b, and 336c is prevented. Due to this technical principle, in this embodiment, airtightness can be guaranteed at the joint area between the two fireproof panels 300.

Meanwhile, in this embodiment, as in the first embodiment, a plurality of bolts are used to prevent integral thermal deformation of the first end 334 or the second end 336 at the joint area of the two fireproof panels 300. (370) and intervening member (372) are used.

However, the fireproof panel 300 of the present embodiment is suitable for installation in a narrow internal space so that the square pipe 174 of the first embodiment does not need to be used, and the square pipe 174 of the first embodiment is used as an intervening member. It is not used. Additionally, in this embodiment, the second insertion groove 316a is provided in a size that can accommodate the entire intervening member 172, and the first insertion groove 114a of the first embodiment is not provided.

In addition, in this embodiment, as in the first embodiment, the intervening member 372 includes fireproof members 372a, 372b and a channel 372b with a “ㄷ” shaped cross-section, but the channels 372b separated in the thickness direction are The two sides are slightly spaced apart from the fireproof member 372a. And the portion of the deformation prevention member 450 that is not inserted into the first end 334 is inserted into this gap.

The bolts 370 are arranged along the vertical direction, penetrate the two corresponding bent portions 236b and the core material 310 in the thickness direction, and are firmly fastened to the intervening member 372 in the second insertion groove 316a. .

If the above bolts 370 and intervening members 372 and 274 are used, the secondary corresponding bent portion 236b cannot move toward the core material 310, so the second end 336 of the remaining fireproof panel 300 ) cannot undergo integral heat deformation that maintains its shape. And since the secondary bending portion 334b is blocked by the secondary corresponding bending portion 336b, the first end 334 maintains its shape in any fireproof panel 300 and is formed with the core material along with the deformation prevention member 350. It becomes impossible to undergo thermal deformation that bends toward (310).
