Abstract

The present invention provides a fireproof frame having fire-resistant, heat-blocking, heat-insulating, and flame-blocking properties and a fireproof system having same.

Description

Fireproof frame and fireproof system equipped therewith

[0001] The present invention relates to a fireproof frame and a fireproof system having the same.

[0002] In buildings, fire-resistant glass is installed as one of the fire containment devices to reduce the spread of fire and ensure stability.

[0003] Fire-resistant glass can be formed by joining multiple sheets of glass using spacers and inserting a fire-resistant material into the hollow layers created by the spacers. Fire-resistant glass can possess fire-resistant, thermal-insulating, heat-insulating, and flame-resistant properties by incorporating a fire-resistant material with these properties.

[0004] These fire-resistant glass panes are installed by means of an installation frame that secures the glass.

[0005] However, in the event of a fire, fireproof glass provides fire resistance, insulation, heat rejection, and flame resistance through its fire-resistant materials. However, the installation frame can expand as its temperature rises. This warping of the installation frame due to thermal expansion can lead to the shattering of the fireproof glass.

[0006] Accordingly, there is a need to equip the installation frame section where fire-resistant glass is installed with technology to prevent the spread of fire.

[0038] Referring to FIGS. 1 to 7, a fire protection system (1000) is configured to include a fire protection frame (100) in which a horizontal frame (110) arranged in the width direction (±x direction) and a vertical frame (120) arranged in the length direction (±y direction) are assembled to form a glass installation space (GS), and fire protection glass (200) installed in the glass installation space (GS).

[0039] The fireproof frame (100) is formed by arranging horizontal frames (110) at the upper and lower portions in the longitudinal direction (±y direction), arranging vertical frames (120) at both sides in the width direction (±x direction) of the horizontal frame (110), and assembling and joining the horizontal frames (110) and the vertical frames (120). The fireproof frame (100) has a square frame shape and provides a glass installation space (GS) on the inside. Fireproof glass (200) is installed in the glass installation space (GS).

[0040] The fireproof frame (100) is provided with a fireproof material (FM) in a cavity (100a) formed inside the fireproof frame (100) along the square frame shape by an assembly-joint structure that connects the insides of the horizontal frame (110) and the vertical frame (120). The fireproof material (FM) may be composed of a material having fire resistance, insulation, heat insulation, and flame-blocking properties. Specifically, the fireproof material (FM) may be composed of a resin composition. The fireproof material (FM) may include a hydrogel, which is an organic polymer, and a silicate hydrogel, which is an inorganic component.

[0041] First, each of the horizontal frame (110) and vertical frame constituting the fireproof frame (100) will be described in detail.

[0042] Referring to FIGS. 1 to 4, the horizontal frame (110) is configured to include a horizontal outer frame (110a) having an empty space inside, and a first communication frame (110b) provided inside the horizontal outer frame (110a) to form a first internal space (IN1).

[0043] The horizontal outer frame (110a) forms the exterior of the horizontal frame (110). The horizontal outer frame (110a) is provided in a form in which both ends in the width direction (±x direction) are inclined downward inwardly in the width direction (±x direction). Accordingly, the horizontal outer frame (110a) has a form in which the width direction (±x direction) dimension increases from the bottom to the top in the length direction (±y direction). The horizontal outer frame (110a) has an empty space inside by having a form in which it penetrates from one side in the width direction (±x direction) to the other side.

[0044] The first flue frame (110b) has a smaller volume than the horizontal outer frame (110a) and is provided in an empty space inside the horizontal outer frame (110a). The first flue frame (110b) is provided in a form in which both ends in the width direction (±x direction) are inclined downward inward in the width direction (±x direction), so that the width direction (±x direction) dimension increases from the bottom to the top in the length direction (±y direction).

[0045] The horizontal frame (110) has one opening of the horizontal outer frame (110a) positioned on the same diagonal of the xy plane of FIGS. 1 and 8 and one opening of the first communication frame (110b) positioned. In addition, the other opening of the horizontal outer frame (110a) is positioned on the same diagonal of the xy plane of FIGS. 1 and 8 and the other opening of the first communication frame (110b) is positioned.

[0046] Accordingly, the one-side opening of the horizontal frame (110) includes a horizontal frame one-side large opening (HX1) positioned on the same diagonal of the xy plane and composed of the one-side opening of the horizontal outer frame (110a), and a horizontal frame one-side small opening (HN1) positioned on the one-side opening of the first communication frame (110b). In addition, the other-side opening of the horizontal frame (110) includes a horizontal frame other-side large opening (HX2) positioned on the same diagonal of the xy plane and composed of the other-side opening of the horizontal outer frame (110a), and a horizontal frame other-side small opening (HN2) positioned on the other-side opening of the first communication frame (110b).

[0047] The horizontal frame (110) has a shape in which the width direction (±x direction) dimension gradually increases from the bottom to the top in the length direction (±y direction) while the first communication frame (110b) is provided inside the horizontal outer frame (110a).

[0048] The fireproof frame (100) is provided with one end including an opening on one side of a horizontal frame (110) and the other end including an opening on the other side thereof at an angle so that the one end including an opening on one side of a vertical frame (120) described below and the other end including an opening on the other side thereof form a diagonal interface (IF) and are in contact and continuously connected. Through this, the fireproof frame (100) has a structure in which the interior is connected in the assembled joint structure of the horizontal frame (110) and the vertical frame (120).

[0049] The fireproof frame (100) includes a first-first support frame (111) and a first-second support frame (112) inside a horizontal outer frame (110a). One end and the other end of the first-first and second support frames (111, 112) in the width direction (±x direction) are provided in a form that slopes downward from the outer side toward the inner side in the width direction (±x direction). Accordingly, one end of the first-first and second support frames (111, 112) is positioned on the same diagonal as one end of the horizontal frame (110) in the xy plane of FIGS. 1 and 8, and the other end of the first-first and 1-2 support frames (111, 112) is positioned on the same diagonal as one end of the horizontal frame (110) in the xy plane of FIGS. 1 and 8.

[0050] The first-first support frame (111) is provided on one side of the first communication frame (110b) in the thickness direction (±z direction), and the first-second support frame (112) is provided on the other side of the first communication frame (110b) in the thickness direction (±z direction) to fix and support the first communication frame (110b) inside the horizontal outer frame (110a).

[0051] The first-first and second-second support frames (111, 112) may be configured to include a first-first separation portion (SP1-1, SP1-1') having a longitudinal (±y-direction) dimension identical to the longitudinal (±y-direction) inner dimension of the horizontal outer frame (110a), and a first-second separation portion (SP1-2, SP1-2') that intersects perpendicularly with the first-first separation portion (SP1-1, SP1-1'). The first-first and second-second support frames (111, 112) are provided such that the first-second separation portion (SP1-2, SP1-2') is positioned at the longitudinal (±y-direction) central portion of the first-first separation portion (SP1-1, SP1-1'), and the first-second separation portion (SP1-2, SP1-2') protrudes in a direction toward the inner wall surface of the horizontal outer frame (110a). The first-first separation section (SP1-1, SP1-1') and the first-second separation section (SP1-2, SP1-2') are provided in an integrated form.

[0052] The first-first separation portion (SP1-1, SP1-1') is provided such that its longitudinal direction (±y direction) upper and lower surfaces are in contact with the longitudinal direction (±y direction) inner upper and lower surfaces of the horizontal outer frame (110a), respectively. One side in the thickness direction (±z direction) of the first-first separation portion (SP1-1) of the first-first support frame (111) is in contact with one side in the thickness direction (±z direction) of the first communication frame (110b), and one side in the thickness direction (±z direction) of the first-first separation portion (SP1-1') of the first-second support frame (112) is in contact with the other side in the thickness direction (±z direction) of the first communication frame (110b). The first communication frame (110b) may preferably be welded and integrated with the first-first spacing portion (SP1-1, SP1-1') in a state where it is positioned at the center of the longitudinal direction (±y direction) of the first-first spacing portion (SP1-1, SP1-1') between the first-first spacing portion (SP1-1) of the first-first support frame (111) and the first-first spacing portion (SP1') of the first-second support frame (112).

[0053] The first-1, 1-2 support frames (111, 112) separate the first communication frame (110b) in the longitudinal direction (±y direction) from the inner wall surface (upper and lower surfaces in the longitudinal direction (±y direction)) of the horizontal outer frame (110a) through the first-1 separation portion (SP1-1, SP1-1'). The first-1, 1-2 support frames (111, 112) separate the first communication frame (110b) in the thickness direction (±z direction) from the inner wall surface (front and rear surfaces in the thickness direction (±z direction)) of the horizontal outer frame (110a) through the first-2 separation portion (SP1-2, SP1-2'). Through this, the first communication frame (110b) is fixedly supported inside the horizontal outer frame (110a) so as to be positioned at the center side (center side based on the length direction and thickness direction (±y, z direction)) of the inside of the horizontal outer frame (110a) while being spaced apart from the inner wall surface of the horizontal outer frame (110a) by the 1-1, 1-2 support frames (111, 112).

[0054] In addition, the horizontal frame (110) is provided with the 1-1 and 1-2 support frames (111, 112) in a form in which the horizontal frame (110) is in contact with the inner wall surface in the longitudinal direction (±y direction) of the horizontal outer frame (110a) through the 1-1 separation portion (SP1-1, SP1-1') and is in contact with the inner wall surface in the thickness direction (±z direction) of the horizontal outer frame (110a) through the 1-2 separation portion (SP1-2, SP1-2'), thereby ensuring higher rigidity.

[0055] The fireproof frame (100) has a partition wall (PT) inside the horizontal frame (110) through the first-1, 1-2 support frames (111, 112). Specifically, each of the first-1, 1-2 support frames (111, 112) is composed of a first-1 separation portion (SP1-1, SP1-1') and a first-2 separation portion (SP1-2, SP1-2') to separate the first communication frame (110b) from the inner wall surface of the horizontal outer frame (110a), and divide the separation space between the horizontal outer frame (110a) and the first communication frame (110b) into a plurality of first independent spaces (ID1). Through this, the 1-1, 1-2 support frames (111, 112) function as a partition wall (PT) that divides the first independent space (ID1) within the horizontal frame (110) of the fire frame (100).

[0056] The fireproof frame (100) has a first independent space (ID1) above and below the first communication frame (110b) in the longitudinal direction (±y direction) through the first-first separation portion (SP1-1) of the first-first support frame (111) and the first-first separation portion (SP1-1') of the first-second support frame (112).

[0057] Through the first-second separation portion (SP1-2) of the first-first support frame (111), a plurality of first independent spaces (ID1) are provided on one side (rear) in the thickness direction (±z direction) of the first communication frame (110b). In the drawing, two first independent spaces (ID1) are provided on one side in the thickness direction (±z direction) of the first communication frame (110b). In addition, through the first-second separation portion (SP1-2') of the first-second support frame (112), a plurality of first independent spaces (ID1) are provided on the other side (front) in the thickness direction (±z direction) of the first communication frame (110b). The first-second separation portion (SP1-2, SP1-2') can protrude in a direction intersecting with the first-first separation portion (SP1-1, SP1-1') to define a plurality of first independent spaces (ID1) in the longitudinal direction (±y direction). In the drawing, two first independent spaces (ID1) are provided on the other side of the thickness direction (±z direction) of the first communication frame (110b).

[0058] The horizontal frame (110) has a plurality of first independent spaces (ID1) on the outside of the first communication frame (110b) along the perimeter of the first communication frame (110b) through the first-1, 1-2 support frames (111, 112).

[0059] The fireproof frame (100) is provided with a fireproof material (FM) in each of a plurality of first independent spaces (ID1). The fireproof material (FM) may be composed of a material having fire resistance, insulation, heat insulation, and flame-resistant properties. Specifically, the fireproof material (FM) may be composed of a resin composition. The fireproof material (FM) may include a hydrogel, which is an organic polymer, and a silicate hydrogel, which is an inorganic component.

[0060] The fire retardant (FM) is injected into the first independent space (ID1) in a liquid state and hardened. The fire frame (100) can coat the inner wall surface of the horizontal outer frame (110a) with a material having adhesive strength. The inner wall surface of the horizontal outer frame (110a) forms the inner wall surfaces of a plurality of first independent spaces (ID1). The fire frame (100) forms a coating surface by coating the inner wall surface of the horizontal outer frame (110a) with a material having adhesive strength, thereby improving the adhesive strength between the first independent space (ID1) and the fire retardant (FM) when the first independent space (ID1) is provided with the fire retardant (FM).

[0061] A fire retardant (FM) is provided in the first independent space (ID1) provided above and below the longitudinal direction (±y direction) of the first communication frame (110b), and a fire retardant (FM) is provided in a plurality (two) of the first independent spaces (ID1) provided in front of the first communication frame (110b) in the thickness direction (±z direction) and a plurality (two) of the first independent spaces (ID1) provided in the rear of the first communication frame (110b) in the thickness direction (±z direction).

[0062] Accordingly, a fire retardant (FM) is provided in a plurality of first independent spaces (ID1) and is provided in a form that surrounds the first communication frame (110b) on the outside of the first communication frame (110b).

[0063] The first-1, 1-2 support frames (111, 112) have an empty space inside. An empty space of the first-1, 1-2 support frames (111, 112) exists between the fire-retardant materials (FM) provided in the plurality of first independent spaces (ID1).

[0064] More specifically, the horizontal frame (110) has a first internal space (IN1) through a first communication frame (110b), and a plurality of first independent spaces (ID1) are defined through the first-1, 1-2 support frames (111, 112) on the outside thereof, and a fire retardant (FM) is provided in the first independent space (ID1). At this time, the first-1, 1-2 support frames (111, 112) are provided in a form having an empty space therein. As a result, an empty space exists between the first internal space (IN1) of the first communication frame (110b) and the inside of the first-1, 1-2 support frames (111, 112) and the fire retardant (FM) inside the horizontal frame (110). The first independent space (ID1) provided on one side and the other side in the thickness direction (±z direction) of the first communication frame (110b) is adjacent to each other with the empty space of the first-second separation portion (SP1-2, SP1-2') in between.

[0065] The horizontal frame (110) is provided with a fire retardant (FM) inside, and an air path is provided through which air can flow by providing an empty space between the fire retardant (FM) through the 1-1 and 1-2 support frames (111, 112).

[0066] The empty space between the fire retardant materials (FM) inside the horizontal frame (110) is connected to the empty space between the fire retardant materials (FM) inside the vertical frame (120) by assembly connection with the vertical frame (120) described later.

[0067] The first internal space (IN1) of the first communication frame (110b) provided between the fireproof materials (FM) is communicated with the second internal space (IN2) of the second communication frame (120b) of the vertical frame (120) described later, thereby forming a main air passage (MP) inside the fireproof frame (100). In addition, the internal empty spaces of the 1-1, 1-2 support frames (111, 112) provided between the fireproof materials (FM) are communicated with the internal empty spaces of the 2-1, 2-2 support frames (121, 122) provided inside the vertical frame (120) described later, thereby forming an auxiliary air passage (AP) provided outside the main air passage (MP).

[0068] The horizontal frame (110) has a form in which the fire retardant (FM) is provided in a plurality of first independent spaces (ID1), so that the fire retardant (FM) is in contact with the inner wall surface of the horizontal outer frame (110a). Since the horizontal outer frame (110a) forms the outer appearance of the horizontal frame (110), it is a part that directly comes into contact with the fire when a fire breaks out. Therefore, it may be the part that is first affected by the heat caused by the fire. The horizontal frame (110) has the fire retardant (FM) provided in the interior of the horizontal outer frame (110a) so as to be in contact with the inner wall surface thereof, so that primary fire prevention is possible through the fire retardant (FM) when a fire breaks out.

[0069] In addition, the horizontal frame (110) has an empty space between the fire retardant materials (FM) through the first internal space (IN1) of the first communication frame (110b) and the internal empty space of the first-1, 1-2 support frames (111, 112). The empty space between the fire retardant materials (FM) can perform an insulating function to prevent heat from being transferred from one first independent space (ID1) among adjacent first independent spaces (ID1) to another first independent space (ID1). As a result, the horizontal frame (110) can prevent the problem of heat from being quickly transferred from an area where the temperature has locally increased due to a fire to another adjacent area, resulting in thermal deformation.

[0070] The fireproof frame (100) may be provided with 1-1, 1-2 support frames (111, 112) each of which is formed with a 1-1 spaced portion (SP1-1, SP1-1') having an elongated shape in the longitudinal direction (±y direction) on the outside of the first communication frame (110b) within the horizontal frame (110). However, the fireproof frame (100) is provided with 1-1, 1-2 support frames (111, 112) including a 1-2 spaced portion (SP1-2, SP1-2') provided in a direction intersecting the 1-1 spaced portions (SP1-1, SP1-1') and the 1-1 spaced portions (SP1-1, SP1-1'), thereby forming more empty space between the fireproof materials (FM) surrounding the first communication frame (110b) and sufficiently securing an air layer between the fireproof materials (FM). Due to this, the horizontal frame (110) can more effectively perform its function of preventing heat from a local temperature rise area from being quickly transferred to other areas in the event of a fire.

[0071] In addition, the empty space between the fireproof materials (FM) of the horizontal frame (110) is continuously connected and communicated with the empty space between the fireproof materials (FM) inside the vertical frame (120) in an assembled state with the vertical frame (120) described later. Through this, air circulating paths (main air path (MP), auxiliary air path (AP)) are formed inside the fireproof frame (100) along the square frame shape of the fireproof frame (100). A detailed description thereof will be described later in the description of the assembled joint structure of the horizontal frame (110) and the vertical frame (120) of the fireproof frame (100).

[0072] Meanwhile, the horizontal frame (110) can have various positions of the first communication frame (110b) inside the horizontal outer frame (110a).

[0073] Figures 5a to 5d are schematic diagrams illustrating an example of the positional relationship of the first communication frame (110b) within the horizontal outer frame (110a). In Figures 5a to 5d, the first-1, 1-2 support frames (SP1-1, SP1-2) and the fire retardant material (FM) are omitted.

[0074] As illustrated in Fig. 5a, the first communication frame (110b) may be positioned at the center in the thickness direction (±z direction) and at the lower side in the length direction (±y direction) within the horizontal outer frame (110a). In this case, the first communication frame (110b) may be provided such that its lower surface is in contact with the inner lower surface of the horizontal outer frame (110a).

[0075] In contrast, as illustrated in FIG. 5b, the first communication frame (110b) may be positioned at the center in the thickness direction (±z direction) of the inside of the horizontal outer frame (110ba) and may be positioned at the upper side in the length direction (±y direction). In this case, the first communication frame (110b) may be provided such that its upper surface is in contact with the inner upper surface of the horizontal outer frame (110a).

[0076] In contrast, as illustrated in FIG. 5c, the first communication frame (110b) may be positioned at the center side in the longitudinal direction (±y direction) of the inside of the horizontal outer frame (110b) and may be positioned at one side (front side, right side of FIG. 5c) in the thickness direction (±z direction). In this case, the first communication frame (110b) may be provided in a state where one side (front side) in the thickness direction (±z direction) is in contact with one inner side (front side) in the thickness direction (±z direction) of the horizontal outer frame (110a).

[0077] In contrast, as illustrated in FIG. 5d, the first communication frame (110b) may be positioned at the center side in the longitudinal direction (±y direction) of the inside of the horizontal outer frame (110b) and may be positioned at the other side (rear side, left side in FIG. 5d) in the thickness direction (±z direction). In this case, the first communication frame (110b) may be provided in a state where the other side (rear side) in the thickness direction (±z direction) is in contact with the inner other side in the thickness direction (±z direction) of the horizontal outer frame (110a).

[0078] In the positional relationship of the first communication frame (110b) within the horizontal outer frame (110a) illustrated in FIGS. 5a to 5d, at least one of the first-1 and 1-2 support frames (SP1-1, SP1-2) may be provided on at least one of one side and the other side of the first communication frame (110b) to fix and support the first communication frame (110b).

[0079] Referring to FIG. 1 and FIG. 6 to FIG. 8, the vertical frame (120) includes a vertical outer frame (120a) having an empty space inside, and a second communication frame (120b) provided inside the vertical outer frame (120a) to form a second internal space (IN2).

[0080] The vertical outer frame (120a) forms the exterior of the vertical frame (120). The upper part in the longitudinal direction (±y direction) of the vertical outer frame (120a) is provided in a form that slopes downward as it goes inward in the width direction (±x direction), and the lower part in the longitudinal direction (±y direction) is provided in a form that slopes upward as it goes inward in the width direction (±x direction). Accordingly, the vertical outer frame (120a) has a form in which the longitudinal direction (±y direction) dimension becomes smaller as it goes inward from the outer part in the width direction (±x direction). The vertical outer frame (120a) has an empty space inside by having a form that penetrates from one side in the longitudinal direction (±y direction) to the other side.

[0081] The second flue frame (120b) has a smaller volume than the vertical outer frame (120a) and is provided in an empty space inside the vertical outer frame (120a). The upper portion in the longitudinal direction (±y direction) of the second flue frame (120b) is provided in a form that slopes downwards as it goes inward in the width direction (±x direction), and the lower portion in the longitudinal direction (±y direction) is provided in a form that slopes upwards as it goes inward in the width direction (±x direction).

[0082] The vertical frame (120) has an upper opening of the vertical outer frame (120a) positioned on the same diagonal of the xy plane of FIGS. 1 and 8, and an upper opening of the second communication frame (120b) positioned thereon. In addition, the lower opening of the vertical outer frame (120a) is positioned on the same diagonal of the xy plane of FIGS. 1 and 8, and a lower opening of the second communication frame (120b) is positioned thereon.

[0083] Accordingly, the upper opening of the vertical frame (120) includes a vertical frame upper large opening (VX1) positioned on the same diagonal of the xy plane and composed of an upper opening of the vertical outer frame (120a), and a vertical frame upper small opening (VN1) positioned on the same diagonal of the xy plane and composed of an upper opening of the second communication frame (120b). In addition, the lower opening of the vertical frame (120) includes a vertical frame lower large opening (VX2) positioned on the same diagonal of the xy plane and composed of a lower opening of the vertical outer frame (120a), and a vertical frame lower small opening (VN2) positioned on the same diagonal of the xy plane and composed of a lower opening of the second communication frame (120b).

[0084] The vertical frame (120) has a shape in which the length direction (±y direction) dimension gradually decreases from the outer side in the width direction (±x direction) to the inner side, while the second communication frame (120b) is provided inside the vertical outer frame (120a).

[0085] The fireproof frame (100) is provided with a second-first support frame (121) and a second-second support frame (122) inside the vertical outer frame (120a). The second-first support frame (121) is provided on one side of the second communication frame (120b) in the thickness direction (±z direction), and the second-second support frame (122) is provided on the other side of the second communication frame (120b) in the thickness direction (±z direction) to fix and support the second communication frame (120b) inside the vertical outer frame (120a).

[0086] The 2-1, 2-2 support frames (121, 122) may be configured to include a 2-1 spacer (SP2-1, SP2-1') having a width direction (±x direction) dimension identical to the width direction (±x direction) inner dimension of the vertical outer frame (120a), and a 2-2 spacer (SP2-2, SP2-2') that vertically intersects the 2-1 spacer (SP2-1, SP2-1'). The 2-1, 2-2 support frames (121, 122) are provided such that the 2-2 spacer (SP2-2, SP2-2') is positioned at the center of the width direction (±x direction) of the 2-1 spacer (SP2-1, SP2-1'), and the 2-2 spacer (SP2-2, SP2-2') protrudes in a direction toward the inner wall surface of the vertical outer frame (120a). The 2-1 separation section (SP2-1, SP2-1') and the 2-2 separation section (SP2-2, SP2-2') are provided in an integrated form.

[0087] The second-first separation portion (SP2-1, SP2-1') is provided such that one side and the other side in the width direction (±x direction) are in contact with one side and the other side in the width direction (±x direction) of the vertical outer frame (120a), respectively. One side in the thickness direction (±z direction) of the second-first separation portion (SP1-1) of the second-first support frame (121) is in contact with one side in the thickness direction (±z direction) of the second communication frame (120b), and one side in the thickness direction (±z direction) of the second-first separation portion (SP1-1') of the second-second support frame (122) is in contact with the other side in the thickness direction (±z direction) of the second communication frame (120b). The second communication frame (120b) may preferably be welded and integrated with the second-first spacing portion (SP2-1, SP2-1') in a state where it is positioned at the center of the width direction (±x direction) of the second-first spacing portion (SP2-1, SP2-1') between the second-first spacing portion (SP1-1) of the second-first support frame (121) and the second-first spacing portion (SP1') of the second-second support frame (122).

[0088] The 2-1, 2-2 support frames (121, 122) separate the second communication frame (120b) in the width direction (±x direction) from the inner wall surface (one side and the other side in the width direction (±x direction)) of the vertical outer frame (120a) through the 2-1 separation portion (SP2-1, SP2-1'). The 2-1, 2-2 support frames (121, 122) separate the second communication frame (120b) in the thickness direction (±z direction) from the inner wall surface (front and rear sides in the thickness direction (±z direction)) of the vertical outer frame (120a) through the 2-2 separation portion (SP2-2, SP2-2'). Through this, the second communication frame (120b) is fixedly supported in a state spaced apart from the inner wall surface of the vertical outer frame (120a) within the vertical outer frame (120a) by the 2-1, 2-2 support frames (121, 122).

[0089] In addition, the vertical frame (120) is provided with the 2-1, 2-2 support frames (121, 122) in a form in which the vertical frame (120) is in contact with the inner wall surface in the longitudinal direction (±y direction) of the vertical outer frame (120a) through the 2-1 separation portion (SP2-1, SP2-1') and is in contact with the inner wall surface in the thickness direction (±z direction) of the vertical outer frame (120a) through the 2-2 separation portion (SP2-2, SP2-2'), thereby ensuring higher rigidity.

[0090] The longitudinal (±y direction) end of the 2-1, 2-2 support frames (121, 122) is provided in a form that slopes downward from the outer side toward the inner side in the width direction (±x direction), and the other end is provided in a form that slopes upward from the outer side toward the inner side in the width direction (±x direction). Accordingly, the upper end of the 2-1, 2-2 support frames (121, 122) is located on the same diagonal as the longitudinal (±y direction) upper end of the vertical frame (120) in the xy plane of FIGS. 1 and 8, and the lower end of the 2-1, 2-2 support frames (121, 122) is located on the same diagonal as the longitudinal (±y direction) lower end of the vertical frame (120) in the xy plane of FIGS. 1 and 8.

[0091] The fireproof frame (100) has a partition wall (PT) inside the vertical frame (120) through the 2-1, 2-2 support frames (121, 122). Specifically, each of the 2-1, 2-2 support frames (121, 122) is composed of a 2-1 separation portion (SP2-1, SP2-1') and a 2-2 separation portion (SP2-2, SP2-2') to separate the second communication frame (120b) from the inner wall surface of the vertical outer frame (120a), and divide the separation space between the vertical outer frame (120a) and the second communication frame (120b) into a plurality of second independent spaces (ID2). Through this, the 2-1, 2-2 support frames (121, 122) function as a partition wall (PT) that divides the second independent space (ID2) within the vertical frame (120) of the fire frame (100).

[0092] The fireproof frame (100) is provided with a second independent space (ID2) on one side and the other side in the width direction (±x direction) of the second communication frame (120b) through the second-first separation portion (SP2-1) of the second-first support frame (121) and the second-first separation portion (SP2-1') of the second-second support frame (122).

[0093] Through the second-second separation portion (SP2-2) of the second-first support frame (121), a plurality of second independent spaces (ID2) are provided on one side (front) in the thickness direction (±z direction) of the second communication frame (120b). In the drawing, two second independent spaces (ID2) are provided on one side (back) in the thickness direction (±z direction) of the second communication frame (120b). In addition, through the second-second separation portion (SP2-2') of the second-second support frame (122), a plurality of second independent spaces (ID2) are provided on the other side (rear) in the thickness direction (±z direction) of the second communication frame (120b). The second-second separation portion (SP2-2, SP2-2') can protrude in a direction intersecting with the second-first separation portion (SP2-1, SP2-1') to define a plurality of second independent spaces (ID2) in the thickness direction (±z direction). In the drawing, two second independent spaces (ID2) are provided on the other side of the second communication frame (120b) in the thickness direction (±z direction).

[0094] The vertical frame (120) has a plurality of second independent spaces (ID2) on the outside of the second communication frame (120b) along the perimeter of the second communication frame (120b) through the 2-1, 2-2 support frames (121, 122).

[0095] The fireproof frame (100) is provided with a fireproof material (FM) in each of a plurality of second independent spaces (ID2). The fireproof material (FM) may be composed of a material having fire resistance, insulation, heat insulation, and flame-resistant properties. Specifically, the fireproof material (FM) may be composed of a resin composition. The fireproof material (FM) may include a hydrogel, which is an organic polymer, and a silicate hydrogel, which is an inorganic component.

[0096] The fire retardant (FM) is injected in a liquid state and hardened. The fire retardant frame (100) can coat the inner wall surface of the vertical outer frame (120a) forming the inner wall surface of the second independent space (ID2) with a material having adhesive strength. The fire retardant frame (100) can improve the adhesive strength between the second independent space (ID2) and the hardened fire retardant (FM) by forming a coating surface with a material having adhesive strength on the inner wall surface of the second independent space (ID2).

[0097] A fire retardant (FM) is provided in the second independent space (ID2) provided on one side and the other side in the width direction (±x direction) of the second communication frame (120b), and a fire retardant (FM) is provided in a plurality (two) of second independent spaces (ID2) provided in the front in the thickness direction (±z direction) of the second communication frame (120b) and a plurality (two) of second independent spaces (ID2) provided in the rear in the thickness direction (±z direction) of the second communication frame (120b).

[0098] Accordingly, a fire retardant (FM) is provided in a plurality of second independent spaces (ID2) inside the vertical frame (120) and is provided in a form that surrounds the second communication frame (120b) on the outside of the second communication frame (120b).

[0099] The 2-1, 2-2 support frames (121, 122) have an empty space inside. Accordingly, an empty space of the 2-1, 2-2 support frames (121, 122) exists between the fire retardant materials (FM) provided in the plurality of second independent spaces (ID2).

[0100] More specifically, the vertical frame (120) has a second internal space (IN2) through the second communication frame (120b), and a plurality of second independent spaces (ID2) are defined through the second-1, 2-2 support frames (121, 122) on the outside thereof, and a fire retardant (FM) is provided in the second independent spaces (ID2). At this time, the second-1, 2-2 support frames (121, 122) are provided in a form having an empty space therein. As a result, between the fire retardant (FM) inside the vertical frame (120), the second internal space (IN2) of the second communication frame (120b) and the empty space inside the second-1, 2-2 support frames (121, 122) exist. The second independent space (ID2) provided on one side and the other side in the thickness direction (±z direction) of the second communication frame (120b) is adjacent to each other with the empty space of the second-second separation portion (SP2-2, SP2-2') in between.

[0101] The vertical frame (120) has a form in which the fire retardant (FM) is in contact with the inner wall surface of the vertical outer frame (120a) by providing a fire retardant (FM) in a plurality of second independent spaces (ID2). Since the vertical outer frame (120a) forms the outer appearance of the vertical frame (120), it is a part that directly comes into contact with the fire when a fire breaks out. Therefore, it may be the part that is first affected by the heat caused by the fire. The vertical frame (120) has the fire retardant (FM) provided inside the vertical outer frame (120a) so as to be in contact with the inner wall surface thereof, thereby enabling primary fire prevention through the fire retardant (FM) when a fire breaks out.

[0102] In addition, the vertical frame (120) has an empty space between the fireproof materials (FM) through the first internal space (IN1) of the second communication frame (120b) and the internal empty space of the second-1, 2-2 support frames (121, 122). The empty space between the fireproof materials (FM) can perform an insulating function to prevent heat from being transferred from one of the adjacent second independent spaces (ID2) to another second independent space (ID2). As a result, the vertical frame (120) can prevent the problem of heat from being quickly transferred from an area where the temperature has locally increased due to a fire to another adjacent area, resulting in thermal deformation.

[0103] The fire frame (100) preferably includes second-1, second-2 support frames (121, 122) including second-1 spacing portions (SP2-1, SP2-1') and second-2 spacing portions (SP2-2, SP2-2') provided in a direction intersecting the second-1 spacing portions (SP2-1, SP2-1') inside the vertical frame (120). Through this, more empty space can be formed between the fire retardant materials (FM) surrounding the second communication frame (120b) inside the vertical frame (120). As a result, the vertical frame (120) can more effectively perform its function of preventing heat from a local temperature rise area from being quickly transferred to other areas when a fire occurs by sufficiently securing an air layer between the fire retardant materials (FM) inside.

[0104] Meanwhile, the vertical frame (120) may have various positional relationships of the second communication frame (120b) within the vertical outer frame (120a). The second communication frame (120b) may be positioned at the center of the vertical outer frame (120a) in the thickness direction (±z direction) and may be provided in a state in which it is offset from at least one side and the other side in the width direction (±x direction). In this case, the second communication frame (120b) may be provided in a state in which at least one side and the other side of the inner side of the vertical outer frame (120a) in the width direction (±x direction) are in contact with the other side.

[0105] In contrast, the second communication frame (120b) may be positioned at the center of the width direction (±x direction) inside the vertical outer frame (120a) and may be provided in a state in which it is biased toward at least one side and the other side in the thickness direction (±z direction). In this case, the second communication frame (120b) may be provided in a state in which at least one side and the other side of the thickness direction (±z direction) inner side of the vertical outer frame (120a) are in contact with the other side.

[0106] In this case, at least one of the 2-1, 2-2 support frames (SP2-1, 2-2) may be provided on at least one of one side and the other side of the second communication frame (120b) in the thickness direction (±z direction).

[0107] Hereinafter, the assembly and joint structure of the horizontal frame (110) and vertical frame (120) of the fireproof frame (100) will be described in detail with reference to FIGS. 1 to 10.

[0108] The fireproof frame (100) is formed by placing horizontal frames (110) at the top and bottom in the length direction (±y direction) and placing vertical frames (120) at one side and the other side in the width direction (±x direction) and assembling and combining the horizontal frames (110) and vertical frames (120).

[0109] Specifically, the fireproof frame (100) contacts one end including an opening on one side of a horizontal frame (110) arranged in the longitudinal direction (±y direction) and an upper end including an upper opening of a vertical frame (120) arranged in the width direction (±x direction), and contacts a lower end including a lower opening of the vertical frame (120) and an end including an opening on one side of a horizontal frame (110) arranged in the longitudinal direction (±y direction).

[0110] In addition, the other end including the other side opening of the horizontal frame (110) arranged in the longitudinal direction (±y direction) is brought into contact with the upper end including the upper opening of the vertical frame (120) arranged in the width direction (±x direction), and the lower end including the lower opening of the vertical frame (120) is brought into contact with the other end including the other side opening of the horizontal frame (110) arranged in the longitudinal direction (±y direction), thereby assembling and connecting the horizontal frame (110) and the vertical frame (120).

[0111] Each of the horizontal frame (110) and the vertical frame (120) has one end and the other end formed in an inclined shape. As a result, the fireproof frame (100) forms an interface (IF) having a diagonal shape between the vertical frame (120) positioned on one side and the other side in the width direction (±x direction) and the horizontal frame (110) positioned on the upper and lower sides in the length direction (±y direction).

[0112] The interface (IF) between the horizontal frame (110) arranged at the top in the longitudinal direction (±y direction) and the vertical frame (120) arranged at one side in the width direction (±x direction) forms a diagonal line that slopes downward from the outside in the width direction (±x direction) toward the inside in the xy plane of FIGS. 1 and 8. The interface (IF) between the horizontal frame (110) arranged at the top in the longitudinal direction (±y direction) and the vertical frame (120) arranged at the other side in the width direction (±x direction) forms a diagonal line that slopes downward from the outside in the width direction (±x direction) toward the inside in the xy plane of FIGS. 1 and 8.

[0113] In addition, the interface (IF) between the horizontal frame (110) arranged at the bottom in the longitudinal direction (±y direction) and the vertical frame (120) arranged at one side in the width direction (±x direction) forms a diagonal line that slopes upward from the outer side in the width direction (±x direction) toward the inner side on the xy plane of FIGS. 1 and 8. The interface (IF) between the horizontal frame (110) arranged at the bottom in the longitudinal direction (±y direction) and the vertical frame (120) arranged at the other side in the width direction (±x direction) forms a diagonal line that slopes upward from the outer side in the width direction (±x direction) toward the inner side on the xy plane of FIGS. 1 and 8.

[0114] Specifically, the fireproof frame (100) is assembled and connected by positioning one end of a horizontal frame (110) arranged in the longitudinal direction (±y direction) and the upper end of a vertical frame (120) arranged in the width direction (±x direction) on the same diagonal of the xy plane of FIGS. 1 and 8. In addition, the other end of the horizontal frame (110) and the upper end of the vertical frame (120) arranged in the width direction (±x direction) on the same diagonal of the xy plane of FIGS. 1 and 8 are assembled and connected.

[0115] Through this, the upper ends of each of the vertical frames (120) arranged on one side and the other side in the width direction (±x direction) at one end and the other end of the horizontal frame (110) arranged in the longitudinal direction (±y direction) are assembled and continuously connected to each other to form a diagonal interface (IF) that slopes downward from the outside to the inside in the width direction (±x direction) in the xy plane of FIGS. 1 and 8 with the horizontal frame (110).

[0116] In addition, one end of a horizontal frame (110) arranged in the longitudinal direction (±y direction) and the lower end of a vertical frame (120) arranged in the width direction (±x direction) are positioned on the same diagonal of the xy plane of FIGS. 1 and 8 and assembled and connected. In addition, the other end of the horizontal frame (110) and the lower end of the vertical frame (120) arranged in the width direction (±x direction) are positioned on the same diagonal of the xy plane of FIGS. 1 and 8 and assembled and connected.

[0117] Through this, the lower ends of each of the vertical frames (120) arranged on one side and the other side in the width direction (±x direction) from one end and the other end of the horizontal frame (110) arranged in the length direction (±y direction) are assembled and continuously connected to each other to form a diagonal interface (IF) that slopes upward from the outside to the inside in the width direction (±x direction) on the xy plane of FIGS. 1 and 8 with the horizontal frame (110).

[0118] The fireproof frame (100) is provided inside the horizontal frame (110) and forms a first independent space (ID1), and the width direction (±x direction) end and the other end of the first-1, 1-2 support frame (111, 112) are also provided in an inclined form. The end and the other end of the first-1, 1-2 support frame (111, 112) are positioned on the same diagonal of the xy plane of FIG. 1 and FIG. 8 as the end and the other end of the horizontal frame (110), respectively.

[0119] In addition, the upper and lower portions in the longitudinal direction (±y direction) of the 2-1, 2-2 support frames (121, 122) formed inside the vertical frame (120) to form the second independent space (ID2) are also provided in an inclined shape. The upper and lower portions of the 2-1, 2-2 support frames (121, 122) are positioned on the same diagonal line of the xy plane of FIGS. 1 and 8 as the upper and lower portions of the vertical frame (120), respectively.

[0120] Through this, the fireproof frame (100) is connected continuously with the interfaces (IF) of the first-1, 1-2 support frames (111, 112) and the second-1, 2-2 support frames (121, 122) forming a diagonal shape in the assembled state of the horizontal frame (110) and the vertical frame (120).

[0121] The fireproof frame (100) has a rectangular frame-shaped exterior in which horizontal frames (110) and vertical frames (120) are continuously connected to form a diagonal interface (IF), and inside the fireproof frame, first-1, 1-2 support frames (111, 112) and second-1, 2-2 support frames (121, 122) are continuously connected to form a diagonal interface (IF). In addition, inside the fireproof frame, the first internal space (IN1) of the horizontal frame (110) and the second internal space (IN2) of the vertical frame (120) are connected to form a main air passage (MP) in the internal cavity (100a).

[0122] The fireproof frame (100) continuously connects the first and second independent spaces (ID1, ID2) by continuously connecting the first-1, 1-2 support frames (111, 112) and the second-1, 2-2 support frames (121, 122) so as to communicate with each other. Through this, a plurality of fireproof independent spaces (FD) are formed that surround the main air path (MP) from the outside.

[0123] A fire independent space (FD) is formed by continuously connecting first and second support frames (111, 112) and second and second support frames (121, 122) to separate the inner wall surface of the fire frame (100) and the main air passage (MP) within a common portion (100a) and to divide the separated space. Therefore, the continuously connected first and second support frames (111, 112) and second and second support frames (121, 122) function as a partition wall (PT) within the fire frame (100), and the partition wall (PT) includes the first and second support frames (111, 112) and the second and second support frames (121, 122).

[0124] A fireproof frame (100) is provided with a fireproof material (FM) in each of a plurality of fireproof independent spaces (FD) that surround the main air path (MP) from the outside. The fireproof material (FM) of the fireproof independent spaces (FD) is provided in a form in which the fireproof materials (FM) provided in each of the first and second independent spaces (ID1, ID2) are connected to each other continuously.

[0125] In the fireproof frame (100), the internal empty spaces of the first-1, 1-2 support frames (111, 112) and the internal empty spaces of the second-1, 2-2 support frames (121, 122) are continuously connected and communicated. As a result, a communication space (GT) exists between the fireproof materials (FM) provided in the fireproof independent space (FD). The communication space (GT) is provided between the adjacent fireproof materials (FM) outside the main air passage (MP) and can function as an auxiliary air passage (AP).

[0126] The fireproof frame (100) of the present invention has a main air passage (MP) within a common portion (100a) and a fireproof material (FM) on the outside thereof. An auxiliary air passage (AP) is provided between the fireproof materials (FM). Accordingly, when a fire occurs, the fireproof frame (100) primarily performs a fireproof function through the fireproof material (FM), and when the temperature of a local area rises, air circulates within the main air passage (MP) and the auxiliary air passage (AP), thereby maintaining a uniform temperature throughout the fireproof frame (100).

[0127] Specifically, in the event of a fire, the fire protection frame (100) may experience a temperature rise in a localized area. At this time, if air circulation does not occur within the fire protection frame (100), a temperature difference may occur between an area where the temperature rises and an area where the temperature does not rise within the entire fire protection frame (100), resulting in temperature unevenness throughout the entire fire protection frame (100). The localized area where the temperature rises may be thermally deformed, which may result in the problem of breaking the fireproof glass (200).

[0128] However, in the fireproof frame (100) of the present invention, when the temperature rises in a local area due to a fire, air circulates within the main air passage (MP) and the auxiliary air passage (AP), thereby eliminating temperature unevenness throughout the fireproof frame (100).

[0129] Fig. 9 is a schematic diagram illustrating air flow in a main air passage (MP) and an auxiliary air passage (AP). The arrows illustrated in the main air passage (MP) and the auxiliary air passage (AP) of Fig. 9 indicate the air circulation direction in the main air passage (MP) and the auxiliary air passage (AP).

[0130] As illustrated in Fig. 9, when the temperature rises in a local area of ​​the fire protection frame (100), air circulates within the main air passage (MP) and the auxiliary air passage (AP). This prevents the temperature from continuing to rise in the local area where the temperature first rose, and allows the temperature of the entire fire protection frame (100) to become uniform as it cools. This prevents the fire protection frame (100) from breaking due to thermal deformation caused by a local temperature rise.

[0131] In addition, the fireproof frame (100) can slow down the heat transfer rate through the auxiliary air path (AP) to prevent heat from being quickly transferred from a local area with an elevated temperature to other areas.

[0132] In addition, the fireproof frame (100) of the present invention can allow the fireproof material (FM) to be hardened with a high density by allowing air to circulate inside through the main air path (MP) and the auxiliary air path (AP) even during the process of injecting the fireproof material (FM) into the fireproof independent space (FD).

[0133] Specifically, the fire retardant (FM) can be injected into the fire frame (100) through an injection hole provided in at least one of the horizontal outer frame (110a) and the vertical outer frame (120a) so as to correspond to each of a plurality of fire independent spaces (FD). The fire retardant (FM) can be injected so as to fill the fire independent spaces (FD) continuously formed along the square frame shape of the fire frame (100).

[0134] Fire retardant (FM) can be injected in liquid form and hardened within a fire-resistant independent space (FD). As the FM hardens into a solid state, heat may be generated. The heat generated as the liquid FM hardens can cause air to circulate within the main air passage (MP) surrounded by the FM and the auxiliary air passage (AP) provided between two adjacent fire-resistant independent spaces (FD).

[0135] In other words, the fire frame (100) circulates air in the main air passage (MP) and the auxiliary air passage (AP) due to the heat generated during the process in which liquid fire retardant (FM) is injected into the fire independent space (FD) and hardens into a solid. This prevents temperature rise in a local area (an area where the fire retardant (FM) hardens relatively first) among the entire area of ​​the fire independent space (FD).

[0136] In the area where the fire retardant (FM) is first injected into a fire-resistant independent space (FD) (located near the injection hole), the FM may harden relatively quickly. This may result in a higher temperature in the area where the FM is first injected compared to other areas.

[0137] At this time, the fire frame (100) prevents the temperature of the area where the fire retardant (FM) is first injected from rising compared to other areas by circulating air in the main air path (MP) and auxiliary air path (AP), and the temperature of the entire area of ​​the fire independent space (FM) can be made uniform.

[0138] If the temperature across a fire-resistant compartment (FD) is not uniform and there is a temperature difference between a localized area and the rest of the compartment, liquid fire retardant (FM) may harden relatively quickly in the area where the temperature has risen. This can lower the density of the hardened FM, further compromising its fire-resistant performance.

[0139] In the fireproof frame (100) of the present invention, air circulates in the main air passage (MP) and the auxiliary air passage (AP) due to the heat generated during the process of hardening a liquid into a solid during the process of injecting a fireproof material (FM). As a result, the fireproof frame (100) can slowly harden the liquid fireproof material (FM) present in the entire area of ​​the fireproof independent space (FD) while maintaining a uniform temperature throughout the entire area of ​​the fireproof independent space (FD). In other words, the fireproof frame (100) can prevent the problem of the liquid fireproof material (FM) hardening relatively rapidly due to a temperature increase in a local area.

[0140] Therefore, the fireproof frame (100) of the present invention can more effectively improve fireproof performance by hardening the fireproof material (FM) with a high density inside a fireproof independent space (FD) with a uniform temperature.

[0141] In addition, the fireproof frame (100) of the present invention has a main air path (MP) to be wrapped by a fireproof material (FM), thereby allowing air to circulate inside the fireproof material (FM), thereby preventing the temperature of the fireproof material (FM) from rising above the deterioration temperature.

[0142]

[0143] A fire protection system (1000) having a fire protection frame (100) of the present invention is provided with fire protection glass (200) in a glass installation space (GS) of the fire protection frame (100).

[0144] Fireproof glass (200) can be formed by joining multiple panes of glass (201) using a spacer (202) and injecting a fireproof material (FM) into the hollow layer formed by the spacer (202). The fireproof material (FM) injected into the hollow layer can be configured identically to the fireproof material (FM) injected into the interior of the fireproof frame (100). Through this, the fireproof glass (200) can be provided with fire resistance, insulation, heat insulation, and flame-blocking performance.

[0145] Referring to FIGS. 2 to 4, a concave groove for installing fireproof glass (200) is formed on the inner surface in the longitudinal direction (±y direction) of the horizontal frame (110). The upper and lower portions in the longitudinal direction (±y direction) of the fireproof glass (200) are each inserted into the concave groove of the horizontal frame (110) arranged above and below in the longitudinal direction (±y direction).

[0146] Referring to FIGS. 2 and 4, the fire frame (100) can be formed by inserting the upper and lower portions of the fire glass (200) into the concave grooves of the horizontal frame (110), thereby applying a heat-resistant material (HR, heat-resistant silicone) to the interface formed when the surface of the fire glass (200) and the horizontal frame (110) come into contact. Through this, the fire glass (200) is fixedly connected to the horizontal frame (110).

[0147] Referring to FIGS. 6 and 7, the fire frame (100) has a concave groove on the inner surface in the width direction (±x direction) of the vertical frame (120). Each of one end and the other end in the width direction (±x direction) of the fire glass (200) is inserted into the concave groove of the vertical frame (120) arranged on one side and the other side in the width direction (±x direction).

[0148] The fire frame (100) can apply a heat-resistant material (HR) to the interface formed when the surface of the fire glass (200) and the vertical frame (120) come into contact by inserting one end and the other end of the fire glass (200) into the concave groove of the vertical frame (120). Through this, the fire glass (200) is fixedly connected to the vertical frame (120).

[0149] The fire protection frame (100) inserts the outer portion of the fire protection glass (200) into a concave groove formed in each of the horizontal frame (110) and the vertical frame (120), and thereby applies a heat-resistant material (HR) to the interface formed between the surface of the fire protection glass (200) and the horizontal frame (110) and the interface formed between the surface of the fire protection glass (200) and the vertical frame (120). As a result, the fire protection system (1000) is installed by fixing the fire protection glass (200) to the glass installation space (GS).

[0150] The fire protection system (1000) of the present invention installs fireproof glass (200) in a fire protection frame (100) that has a fireproof material (FM) inside and has an overall temperature uniformity through air circulation in a main air passage (MP) and an auxiliary air passage (AP). As a result, the fire protection system (1000) can effectively prevent the spread of fire by preventing the problem of the fireproof glass (200) being broken due to a temperature rise in a local area of ​​the fire protection frame (100).

[0151] Meanwhile, the fire prevention system (1000) of the present invention may be provided with a fireproof material (first fireproof material (NM1), second fireproof material (NM2)) in a fireproof frame (100) and may also be fixedly connected with fireproof glass (200) in a glass installation space (GS).

[0152] Fig. 10 is a schematic diagram showing a state in which fireproof glass (200) is installed in a fireproof frame (100) equipped with first and second non-combustible materials (NM1, NM2). In Fig. 10, as an example, one end of a horizontal frame (110) arranged in the lower longitudinal direction (±y direction) is enlarged and shown.

[0153] Referring to Fig. 10, the horizontal frame (110) may be provided with a frame coupling portion (110a') that is fixedly coupled to the horizontal outer frame (110a) at the upper portion in the longitudinal direction (±y direction). When the horizontal frame (110) includes the frame coupling portion (110a'), the horizontal outer frame (110a) may preferably have a shape in which one side (for example, the rear side) in the thickness direction (±z direction) protrudes more than the other side (the front side) in the longitudinal direction (±y direction). The horizontal frame (110) may form a concave groove shape at the upper portion in the longitudinal direction (±y direction) by coupling the frame coupling portion (110a') to the front side in the thickness direction (±z direction) of the horizontal outer frame (110a).

[0154] The fireproof frame (100) may be provided with a first fireproof material (NM1) on an inner wall surface in the thickness direction (±z direction) before inserting the lower part of the fireproof glass (200) into a concave groove on the upper part in the longitudinal direction (±y direction) of the horizontal frame (110). The first fireproof material (NM1) may be bonded or adhered to the inner wall surface of the groove. The first fireproof material (NM1) may be composed of a ceramic material, for example. The material constituting the first fireproof material (NM1) is not limited thereto and may include a material having a fireproof property.

[0155] The fireproof frame (100) may be provided with a second fireproof material (NM2) on the bottom surface of the concave groove of the horizontal frame (110). The second fireproof material (NM2) may be provided between the first fireproof materials (NM1) facing each other in the thickness direction (±z direction). The second fireproof material (NM2) may be composed of a material having fireproof properties.

[0156] The second fireproof material (NM2) can be provided along the bottom surface of the groove of the horizontal frame (110) so as to be continuously provided along the glass installation space (GS) of the fireproof frame (100).

[0157] In contrast, the second fireproof material (NM2) may not be continuously provided along the bottom surface of the groove of the horizontal frame (110), but may be formed only on one side and the other side in the width direction (±x direction) of the lower portion of the fireproof glass (200) while the lower portion of the fireproof glass (200) is inserted between the first fireproof materials (NM1) facing each other in the thickness direction (±z direction).

[0158] The fireproof frame (100) can form a concave groove shape through the first and second fireproof materials (NM2) by providing a second fireproof material (NM2) on the bottom surface of the concave groove of the horizontal frame (110) and providing a first fireproof material (NM1) on the inner wall surface. The fireproof frame (100) can provide the first and second fireproof materials (NM1, NM2) in the concave groove of the horizontal frame (110), and the lower part of the fireproof glass (200) can be inserted into the concave groove formed by the first and second fireproof materials (NM1, NM2).

[0159] Accordingly, the lower part of the fireproof glass (200) can be inserted in a concave groove of a horizontal frame (110) having the first and second fireproof materials (NM1, NM2) in a form in which it is wrapped by the first and second fireproof materials (NM1, NM2).

[0160] The fireproof frame (100) can be fixedly connected to the horizontal outer frame (110a) by, preferably, providing a fireproof material (NM1, NM2) on the front side in the thickness direction (±z direction) of the protruding portion of the horizontal outer frame (110a) before connecting the frame connecting portion (110a') to the horizontal outer frame (110a), and then arranging the frame connecting portion (110a') on the front side in the thickness direction (±z direction) of the fireproof material (NM1, NM2). The frame connecting portion (110a') and the horizontal outer frame (110a) can be fixedly connected by a fixing means (BT).

[0161] More specifically, the fireproof frame (100) may be provided with a first fireproof material (NM1) so as to be in contact with the front surface in the thickness direction (±z direction) of the protruding portion of the horizontal outer frame (110a), and a second fireproof material (NM2) so as to be in contact with the upper surface of the central portion of the horizontal outer frame (110a) on the front side in the thickness direction (±z direction) of the first fireproof material (NM1). The second fireproof material (NM2) may be provided with a longitudinal dimension (±y direction) smaller than the longitudinal dimension (±y direction) of the first fireproof material (NM1) so as to be stepped in the longitudinal direction (±y direction) from the first fireproof material (NM1).

[0162] Then, the fireproof frame (100) may be provided with the first fireproof material (NM1) on the front surface in the thickness direction (±z direction) of the second fireproof material (NM2) so as to be in contact with the rear surface in the thickness direction (±z direction) of the frame joint (110a') that is subsequently joined to the horizontal outer frame (110a).

[0163] Through this, the fireproof frame (100) can form a concave groove by the first and second fireproof materials (NM1, NM2) before joining the frame joint (110a') to the horizontal outer frame (110a).

[0164] In contrast, the fireproof frame (100) may be provided with first and second fireproof materials (NM1, NM2) in the concave grooves of the horizontal frame (110) while the frame joint (110a') is fixedly connected to the horizontal outer frame (110a) so as to face the protruding portion of the horizontal outer frame (110a) in the thickness direction (±z direction).

[0165] The fire frame (100) is provided with first and second fireproof materials (NM1, NM2) in the concave grooves of the horizontal frame (110), the lower part of the fireproof glass (200) is inserted into the concave grooves formed by the first and second fireproof materials (NM1, NM2), and a heat-resistant material (HR) can be applied to cover the interface formed between the first fireproof material (NM1) and the lower surface of the fireproof glass (200). Although the heat-resistant material (HR) is omitted in Fig. 10, the form in which the heat-resistant material (HR) is applied to the interface is the same as that illustrated in Fig. 4. Preferably, the heat-resistant material (HR) can be applied to cover the interface between the first non-combustible material (NM1) and the protruding portion of the horizontal outer frame (110a), the interface formed between the first non-combustible material (NM1) and the lower surface of the fire-resistant glass (200), and the interface between the frame joint (110a') and the first non-combustible material (NM1).

[0166] The fireproof frame (100) may also be provided with first and second fireproof materials (NM1, NM2) in the concave grooves of the vertical frame (120) forming the glass installation space (GS). In this case, preferably, the vertical frame (120) may include a vertical outer frame (120a) and a frame joint (110a') coupled to the vertical outer frame (120a).

[0167] The fire prevention system (1000) of the present invention can more effectively prevent the spread of fire and prevent the breakage of the fire prevention glass (200) in the event of a fire by fixing the fire prevention frame (100) and the fire prevention glass (200) while providing first and second fire-retardant materials (NM1, NM2) in the concave groove of the horizontal frame (110) forming the glass installation space (GS) and the concave groove of the vertical frame (120).

[0168] As described above, the present invention has been described with reference to preferred embodiments thereof, but it will be apparent to those skilled in the art that various modifications or variations may be made to the present invention without departing from the spirit and scope of the present invention as set forth in the following claims.
