Description

  The present invention relates to a load-bearing wall that resists horizontal loads applied to buildings such as earthquakes and winds, and more particularly to a load-bearing wall having fireproof performance.

  When designing a building, seismic design is performed by a method determined by the type of structure. For example, in wooden construction, wall quantity design is performed in order to ensure earthquake resistance, and this wall quantity design determines the required length of the load-bearing wall of the building in each of the vertical and horizontal directions of the plan view. The

  Conventionally, as a bearing wall used in such a building, a strut is provided on a frame surface surrounded by columns and beams or a foundation, or a plywood is fixed to the columns and beams with nails. Things are known. As for the load bearing wall generally used in this way, the wall magnification is determined by the Building Standard Act Construction Ordinance. The load-bearing wall is configured so that the wall amount calculated by “wall magnification × bearing wall length” satisfies the above-described wall amount design value. The “length of the load bearing wall” is the length shown on the plan view of the building.

  By the way, a panel material made of a steel plate having lattice-like ribs has been proposed as a load-bearing wall panel material having openings capable of daylighting and ventilation (Patent Document 1).

Further, Patent Document 2 proposes a synthetic resin panel material having grid-like ribs. The panel material of Patent Document 2 is lighter than the panel material of Patent Document 1 made of a steel plate, has high earthquake resistance with a simple configuration, and further has excellent weather resistance and corrosion resistance. There is.
JP 2002-70213 A JP 2006-77565 A

  However, although Patent Documents 1 and 2 each describe a bearing wall having seismic performance, for example, a fireproof performance suitable for a 30-minute fireproof structure, a quasi-fireproof 45-minute structure, etc. in accordance with the Building Standards Act enforcement order. No mention is made of the structure.

  Moreover, as the panel material of the load bearing wall, as described above, the load bearing wall of Patent Document 2 is superior to the load bearing wall of Patent Document 1 in that it has a light weight and simple configuration and has high earthquake resistance. A load bearing wall having fire and fire resistance performance utilizing the panel material made of 2 synthetic resin has been desired. Moreover, since the panel material of patent document 2 has translucency by the grid | lattice-like rib, the bearing wall which has both lighting performance and fireproof performance was also desired.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a load-bearing wall that has a light-proof and simple structure and high earthquake resistance, as well as fireproof and lighting performance.

  In order to achieve the above object, the invention according to claim 1 is attached to a part or the whole of the frame surface surrounded by the pillars, beams and foundations of the building, and has a plurality of grids in the vertical direction and the horizontal direction. A rectangular panel material made of synthetic resin in which a rib is formed, a heat insulating material having translucency with respect to the panel material, and a fireproof glass arranged with a predetermined gap, are provided. .

  The invention described in claim 2 is characterized in that, in claim 1, the heat insulating material is a blanket having crystalline alumina as a main base material.

  In order to achieve the above object, the invention according to claim 3 is attached to a part or the whole of the frame surface surrounded by the pillars, beams and foundations of the building, and has a plurality of grids in the vertical and horizontal directions. A rectangular panel material made of synthetic resin with a rib-like rib formed thereon, heat insulating particles filled in openings between lattice ribs of the panel material, and the heat insulating particles sandwiching the panel material from both sides And a light-transmitting plate-like body, and at least one of the plate-like bodies, or a fireproof glass disposed with a predetermined gap with respect to both plate-like bodies. Features.

  The invention described in claim 4 is characterized in that, in claim 3, at least one of the plate-like bodies or both of the plate-like bodies are fire-proof glass.

  A fifth aspect of the present invention is characterized in that in the third and fourth aspects, a heat insulating particle layer having a predetermined thickness is formed between the plate-like body and the panel material 12.

  A sixth aspect of the present invention is characterized in that in the first, second, third, or fourth aspect, the fireproof glass is a meshed glass or a low expansion glass.

  According to the first aspect of the present invention, since the panel material of the load bearing wall is made of synthetic resin and a plurality of grid ribs are formed in the vertical direction and the horizontal direction, it is lightweight and has a simple structure and high earthquake resistance. A bearing wall having performance can be provided. In addition, by reducing the weight, the center of gravity does not increase even when installed on the second floor of a wooden building or the like, so that the shaking of the wooden building does not increase during an earthquake.

  Further, the load bearing wall of claim 1 is configured by arranging a heat insulating material having translucency with respect to the panel material and a fireproof glass with a predetermined gap, so that the load bearing wall having fireproof performance and lighting performance, for example, It is possible to provide a load-bearing wall suitable for a 30-minute fireproof structure and a semi-fireproof 45-minute structure. Furthermore, since heat is released to the back surface of the fire glass by the gap, the temperature rise of the fire glass is suppressed, and the softening and melting of the fire glass is about the same as when the fire glass is used alone.

  According to invention of Claim 2, it is preferable that the said heat insulating material is made into the blanket which uses crystalline alumina as a main base material. Since this blanket has translucency, it is possible to provide a bearing wall with daylighting properties by combining a synthetic resin panel material in which lattice-shaped ribs are formed, a fireproof glass having transparency, and the blanket. . Here, a wall using a panel material having translucency is also referred to as a wall having daylighting properties. In addition, the light-transmitting property here may be light transmitting and may not have transparency.

  According to the invention described in claim 3, the panel material of the load bearing wall is made of a synthetic resin, and a plurality of lattice ribs are formed in the vertical direction and the horizontal direction, so that the structure has high earthquake resistance with a simple configuration. Can provide a bearing wall. In addition, by reducing the weight, the center of gravity does not increase even when installed on the second floor of a wooden building or the like, so that the shaking of the wooden building does not increase during an earthquake.

  The bearing wall according to claim 3 fills the openings between the lattice ribs of the panel material with heat insulating particles, and sandwiches the panel material from both sides to prevent leakage of the heat insulating particles from the panel material. Since the fireproof glass is arranged with a predetermined gap on the outside of the plate-like body, a load bearing wall having fireproof performance can be provided. Furthermore, since heat is released to the back surface of the fire glass by the gap, the temperature rise of the fire glass is suppressed, and the softening and melting of the fire glass is about the same as when the fire glass is used alone.

  Here, filling means that the heat insulating particles fill the openings between the lattice ribs of the panel material. The state of filling is most preferably a state in which the heat insulating particles are closely packed in the opening, but a space that is partially filled with the heat insulating particles in the opening (that is, larger than the size in which the heat insulating particles can enter). The space in which the heat insulating particles do not enter, and does not include the space generated between the heat insulating particles that are closely packed with the heat insulating particles). It is sufficient that the space is not connected to (indoor-outdoor direction).

  In addition, to prevent leakage of the heat insulating particles from the panel material by sandwiching the panel material from both sides with the plate material, when the two plate materials are closely attached to the panel material, the heat insulating particles This means that it does not come out of the opening of the panel material, and when the panel material is sandwiched in a state where at least one plate-like body described later is not in close contact with the panel material, the opening of the panel material and the heat insulating particles It means not coming out from the layer to the opposite side through the plate-like body.

  When the heat-insulating particles are filled in the openings between the lattice ribs with a relatively large particle size, light is transmitted through the gaps between the particles, but the entire bearing wall has daylighting properties. Also, if transparent or semi-transparent heat insulating particles are used, the heat insulating particles themselves have translucency, so that even if the openings between the lattice ribs are filled, the translucent and light-bearing bearing walls are available. Can be provided. Silica particles can be exemplified as the translucent heat insulating particles.

  According to invention of Claim 4, it is preferable to apply fire prevention glass as a plate-shaped object of Claim 3.

  According to invention of Claim 5, it is preferable to form the heat insulating particle layer of predetermined thickness between a plate-shaped object and a panel material. Further, by selecting silica particles as the heat insulating particles, it is possible to obtain a bearing wall having high heat insulating properties and daylighting properties.

  According to invention of Claim 6, it is preferable to apply netted glass or low expansion glass as fireproof glass. The netted glass plate has transparency, and when the glass is broken, there is an advantage that it is difficult for fragments to fall off due to the enclosed metal net, and that intrusion of fire or sparks can be prevented. In addition, the low expansion glass has fireproof performance, and when broken, the fragments are not fine, and since the transparency is high, it is possible to provide a bearing wall with high daylighting.

  Hereinafter, a preferred embodiment of a load bearing wall according to the present invention will be described in detail with reference to the accompanying drawings.

  FIG. 1 is a perspective view of a load bearing wall 10 having fire resistance and lighting performance according to the first embodiment. In addition, in FIG. 1, in order to explain the configuration of the load bearing wall 10, a panel material 12 constituting the load bearing wall 10, an alumina blanket (insulating material (Mitsubishi Chemical Corporation) having a translucent crystalline alumina as a main base material. (Supplied by Shiseido Co., Ltd .: trade name “MAFTEC”)) 14 and netted glass plate (fireproof glass) 16, the upper portions of each of the alumina blanket 14 and the netted glass plate 16 are partially cut away. .

  In addition, although alumina blanket 14 is illustrated as a heat insulating material in embodiment, it is not limited to this, If it is a cloth-like or sheet-like heat insulating material which has heat insulation and translucency, it is applicable. it can. Moreover, in embodiment, although the netted glass plate 16 is illustrated as fireproof glass, it is not limited to this, Fireproof glass, such as low expansion glass, can also be illustrated.

  According to FIG. 1, in a wooden building, a rectangular panel material 12, a rectangular alumina blanket 14, and a rectangular shape are formed on a frame surface surrounded by a base 18, a beam 20, and left and right columns 22, 22. The load bearing wall 10 is configured by attaching the netted glass plate 16. This mounting structure will be described later.

  As shown in FIG. 2, the panel member 12 has vertical sides 12A, 12A on both sides thereof attached to pillars 22, 22 installed on both sides of the panel member 12 via mounting brackets 24, 24. , Fixed to the pillars 22 and 22. The two mounting brackets 24 shown in FIG. 2 are arranged at predetermined intervals on each vertical side portion 12A, but the mounting position and the number of mounting brackets 24 are not limited to this, and the panel material 12 is not limited thereto. The mounting strength (predetermined wall strength magnification) can be secured at a position and number of positions.

  FIG. 3 is an enlarged perspective view showing a part of the panel material 12. According to the figure, the ribs 28, 28... Regularly arranged in both the vertical and horizontal directions are integrally formed in a lattice shape inside the quadrilateral frame body 26 to constitute the panel material 12. The vertical side portions 12A and 12A (only one vertical side portion 12A is shown in FIG. 3) on both sides of the frame body 26 are fixed to the column 22 via the mounting bracket 24 shown in FIG.

  The material of the panel material 12 is, for example, a high-strength hard synthetic resin, and a glass fiber reinforced plastic (FRP) having translucency is a preferable example. Alternatively, an acrylic resin or a vinyl chloride resin is used. The panel material 12 exhibits strength against in-plane longitudinal and lateral loads by a plurality of ribs 28 arranged in a lattice pattern.

  In the embodiment, a panel material 12 made of FRP will be described. When the panel material 12 is made of FRP, there is an advantage that it is lighter in weight and excellent in weather resistance and corrosion resistance than those made of metal such as steel. Moreover, since the panel material 12 made from FRP has translucency in the raw material itself, it is excellent in daylighting property and can provide a bright and open bearing wall. Further, by using the panel material 12 having the grid-like ribs 28, 28,..., High earthquake resistance can be obtained with a simple configuration.

  With respect to the thickness of the panel material 12, as long as sufficient strength can be obtained as a load bearing wall, it is preferably as thin as possible in terms of space securing and arrangement of other members, and is practically preferably 20 to 100 mm. The thickness of the rib 28 is preferably 3 to 30 mm. Within this range, 3 to 7 mm is particularly preferable. Here, in the case of the rib 28 in which the taper is formed, the thickness of the average value is referred to as the thickness of the rib 28. The size of the lattice portion surrounded by the ribs 28 is preferably measured by the center line of the ribs 28. When the shape of the lattice is square, 20 × 20 to 200 × 200 mm is preferable. Within this range, 20 × 20 to 55 × 55 mm is particularly preferable. Moreover, when the shape of the lattice is rectangular, the short side is preferably 20 to 150 mm and the long side is preferably 30 to 300 mm. Also, the direction of the rectangular lattice may be horizontal or vertical with respect to the horizontal. Further, the square lattice may have a shape inclined by 45 degrees with respect to the horizontal.

  Since the panel material 12 has the opening 30 surrounded by the ribs 28, light enters through the opening, and the panel material 12 is provided with a translucent alumina blanket 14 and a meshed glass plate 16 to constitute a wall surface. Thus, it is possible to configure the bearing wall 10 having daylighting and fire resistance.

  4 is an enlarged front view of the mounting bracket 24, and FIG. 5 is a cross-sectional view of the mounting bracket 24 along the line AA in FIG.

  The mounting bracket 24 includes four truncated pyramid shaped blocks fitted into a tapered opening 30 formed by an L-shaped bracket 32 spanned between the panel material 12 and the pillar 22 and a rib 28. 34, four bolts 36 that fix the bracket 32 to the block 34 through the opening 30, and four screws 38 that fix the bracket 32 to the column 22.

  As shown in FIG. 5, the opening 30 of the panel material 12 has a tapered shape in which the width increases from one surface of the panel material 12 toward the other surface. Using this taper shape, a truncated pyramid shaped block 34 is fitted into the opening 30, and a panel 36 is formed by the block 34 and the bracket 32 by a bolt 36 screwed into the block 34 from the opposite side of the fitting direction. A bracket 32 is fixed to the panel material 12 so as to sandwich the material 12. In this way, when the bracket 24 fixed to the panel material 12 is fixed to the column 22, the screw 38 is used as described above. Thereby, the vertical sides 12 </ b> A and 12 </ b> A on both sides of the panel material 12 are fixed to the columns 22 and 22.

  FIG. 6 is a longitudinal sectional view of the load bearing wall 10 shown in FIG. 1, showing details of the mounting structure of the alumina blanket 14 and the meshed glass plate 16.

  The bearing wall 10 includes a panel material 12, an alumina blanket 14 and a meshed glass plate 16 disposed on the outdoor side with respect to the panel material 12, and an alumina blanket 15 and a mesh disposed on the indoor side with respect to the panel material 12. The glass plate 17 is comprised of.

  The alumina blankets 14 and 15 are attached to both surfaces of the panel material 12. The meshed glass plate 16 is disposed with a predetermined gap 40 with respect to the alumina blanket 14, and the meshed glass plate 17 is disposed with a predetermined gap 42 with respect to the alumina blanket 15.

  The netted glass plate 16 is fixed via a sealing material 48 and a heating foam material 50. That is, the peripheral portion of the netted glass plate 16 is in the concave portion 47 of the gypsum board (calcium silicate plate) 46 (a portion where a part of the gypsum board 46 is cut out), the gypsum board 46, the sealing material 48, and the netted glass plate 16. The heating foam 50 and the alumina blanket 14 are arranged and fixed in contact with each other in this order. The gypsum board 46 has its upper side fixed to the beam 20 with screws 44 and its lower side fixed to the base 18 with screws 52.

  On the other hand, the meshed glass plate 17 has a peripheral portion fixed to a gap 57 between the pair of steel materials 54 and 56 via a sealing material 58 and a heating foam material 60. That is, the peripheral portion of the meshed glass plate 17 is arranged and fixed so as to contact the steel material 54, the sealing material 58, the meshed glass plate 17, the heating foam material 60, and the steel material 56 in this order from the steel material 54 side. The pair of steel materials 54 and 56 are fixed to the base 18, the beam 20, and the columns 22 and 22 with screws (not shown).

  Thus, if the heating foam materials 50 and 60 are arrange | positioned around the meshed glass plates 16 and 17, the heating foam materials 50 and 60 will foam by the heat transfer from the meshed glass plates 16 and 17 at the time of a fire, Since the force to sandwich and hold the meshed glass plates 16 and 17 increases with temperature, the meshed glass plates 16 and 17 can be prevented from falling off.

  Further, according to the bearing wall 10, the predetermined gap 40 that exhibits heat insulation is provided between the glass plate 16 on the outdoor side and the alumina blanket 14. Heat release to Thereby, the temperature rise of the meshed glass plate 16 is suppressed, and the softening or melting of the meshed glass plate 16 is about the same as when the meshed glass is used alone. This is an advantageous fire-proof structure against the spread of fire from the outdoor side, but since a predetermined gap 42 that exhibits heat insulation is also provided between the glass plate 17 on the indoor side and the alumina blanket 15, it is from the indoor side. It has an advantageous fireproof structure even in the spread of fire.

  On the other hand, since the panel material 12 has an opening, light is transmitted through the opening. Further, if the panel material is made of translucent FRP, the panel material 12 itself is also translucent and therefore translucent. The alumina blankets 14 and 15 themselves are also members having translucency (light transmittance: 7%; the above-mentioned MAFTEC thickness 7.5 mm), and the netted glass plates 16 and 17 are also highly transparent glass plates. Therefore, it is the bearing wall 10 with daylighting.

  By the way, if the bearing wall 10 is sealed, the internal pressure is increased by heating, and the meshed glass plates 16 and 17 are pushed outward by the internal pressure, and the deformation of the meshed glass plates 16 and 17 is increased. In order to prevent this, grooves (not shown) for releasing pressure are formed in the heating foam materials 50 and 60 and the sealing materials 48 and 58 of the meshed glass plates 16 and 17, and the decomposition gas is released to the outside. It is like that.

  According to the load bearing wall 10 configured as described above, the panel material 12 is manufactured by FRP, and the plurality of grid-like ribs 28 are formed in the vertical direction and the horizontal direction. The bearing wall 10 having seismic performance can be provided.

  In addition, since the load bearing wall 10 is configured by arranging the meshed glass plates 16 and 17 with the alumina blankets 14 and 15 and the predetermined gaps 42 and 44 with respect to the panel material 12, the load bearing wall having fireproof performance, That is, it is possible to provide the load bearing wall 10 that conforms to the 30-minute fireproof structure and the semi-fireproof 45-minute structure. Furthermore, since heat is released to the back surfaces of the meshed glass plates 16 and 17 by the gaps 42 and 44, the temperature rise of the meshed glass plates 16 and 17 is suppressed, and the meshed glass plates 16 and 17 are softened or melted. Is the same level as when using netted glass alone.

  Furthermore, the heat insulating material of the load-bearing wall 10 is a heat insulating material having translucency, and includes a panel material 12 made of FRP in which lattice-like ribs 28 are formed, and a meshed glass plate 16 and 17 having transparency. The load bearing wall 10 with daylighting can be provided by the combination.

  FIG. 7 is an enlarged cross-sectional view of a main part of the load bearing wall 10 shown in FIG. 6, and a to e showing respective dimensions are described. a is the thickness of the panel material 12, 30 mm, b is the thickness of the alumina blankets 14 and 15, 7.5 mm, c is the gap 40 and 10 mm, d is the gap 42 and 34 mm, e is a meshed glass plate It is a thickness of 16, 17 and is 6.8 mm. That is, the total wall thickness of the load bearing wall 10 is 99.6 mm. In addition, although this dimension is an example, it is the load-bearing wall 10 which adapts to a 30-minute fireproof structure, a semi-fireproof 45-minute structure, etc. based on the Building Standard Law enforcement order.

  FIG. 8 is a longitudinal cross-sectional view of the load bearing wall 100 having fireproof performance and daylighting performance according to the second embodiment, which is the same as the load bearing wall 10 of the first embodiment shown in FIGS. Similar members will be described with the same reference numerals.

  The bearing wall 100 includes a panel material 12, heat insulating particles (silica particles (trade name “nanogel” manufactured by CABOT)) filled in the opening 30 surrounded by the ribs 28 of the panel material 12, An inner netted glass plate (plate-like body) 72 and netted glass plate 16 arranged on the outdoor side with respect to the material 12, and an inner netted glass plate arranged on the indoor side with respect to the panel material 12 ( Plate-like body) 74 and a meshed glass plate 17.

  The meshed glass plate 72 is disposed at a predetermined interval with respect to the outdoor side surface of the panel material 12. Further, the netted glass plate 74 is adhered to the outdoor side surface of the panel material 12 and is in close contact with the peripheral portion of the panel material 12 via the calcium silicate plate 76 disposed on the peripheral portion thereof. Thus, the opening 30 is sealed by the meshed glass plates 72 and 74 disposed on both sides of the panel material 12, and the silica particles 70 are filled in the gap between the opening 30 and the panel material 12 and the meshed glass plate 74. The panel material 12 is not leaked.

  The meshed glass plate 16 is disposed with a predetermined gap 78 with respect to the meshed glass plate 72. The peripheral portion of the netted glass plate 16 is fixed to the concave portion 47 of the gypsum board 46 via a sealing material 48 and a heating foam material 50. That is, the peripheral part of the meshed glass plate 16 is arranged and fixed in the order of the gypsum board 46, the sealing material 48, the meshed glass plate 16, the heating foam material 50, and the meshed glass plate 72. The gypsum board 46 has its upper side fixed to the beam 20 with screws 44 and its lower side fixed to the base 18 with screws 52.

  When the heating foam material 50 is arranged around the meshed glass plate 16 in this manner, the heating foam material 50 foams due to heat transfer from the meshed glass plate 16 in the event of a fire, thereby sandwiching the meshed glass plate 16. Since the attaching and holding force increases with temperature, the netted glass plate 16 can be prevented from falling off.

  On the other hand, the meshed glass plate 17 is in close contact with the peripheral portion of the meshed glass plate 74 via a calcium silicate plate 80 disposed on the peripheral portion thereof. Accordingly, the meshed glass plate 17 is disposed with a predetermined gap 82 with respect to the meshed glass plate 74. A metal 84 is fixed to the periphery of the indoor side surface of the meshed glass plate 17, and the upper side of the metal 84 is fixed to the beam 20 by a screw 86, and the lower side is screwed to the base 18. It is fixed by 88.

  According to the load-bearing wall 100, since the predetermined gap 78 that exhibits heat insulation is provided between the outdoor side glass plate 16 and the inner netted glass plate 72, the netted glass plate 16 is formed by the gap 78. The heat is released to the back surface. Thereby, the temperature rise of the meshed glass plate 16 is suppressed, and the softening or melting of the meshed glass plate 16 is about the same as when the meshed glass is used alone. Although this is an advantageous fireproof and fireproof structure against the spread of fire from the outdoor side, a predetermined gap 82 that exhibits heat insulation is also provided between the glass plate 17 on the indoor side and the glass plate 74 with the net inside. In addition, it has a fireproof structure that is advantageous even in the spread of fire from the indoor side.

  On the other hand, the panel material 12 (a panel having a panel thickness of 30 mm, a pitch of 30 mm, and an opening size of 25 × 25 mm) is a lattice-like panel material having an aperture ratio of about 70%, and the panel material 12 itself is also made of FRP. Translucent. The silica particles 70 are also translucent particles (light transmittance 33%: measured when the particles are 30 mm thick), and the meshed glass plates 16, 17, 72, 74 are also transparent. Since it is a high glass plate, it is a bearing wall 100 with daylighting.

  Further, the silica particles 70 have high heat insulating properties (18 mmW / mhr ° C.), and good heat insulating properties can be obtained by filling the silica particles 70 into the openings 30 of the lattice of the panel material 12. Further, a heat-insulating particle layer 71 having a predetermined thickness between the meshed glass plate 74 holding the silica particles 70 and the panel material 12 (here, since silica particles are used for the heat-insulating particles, hereinafter, silica By forming the particle layer 71, heat transfer from the meshed glass plate 74 to the panel material 12 can be suppressed. Here, the silica particle layer 71 is referred to as a silica particle layer 71 in FIG. 8 and FIG. 9 in which the silica particles 70 are included in the interval between the meshed glass plate 72 and the panel material 12. Here, although the example which has a space | interval between the meshed glass plate 72 and the panel material 12 was shown, the thing without the space | interval, ie, the structure which affixed the meshed glass plate 72 to the panel material 12, may be sufficient.

  In addition, although the netted glass plates 72 and 74 are exemplified as the plate-like body, the present invention is not limited to this, as long as it is translucent and can prevent leakage of the silica particles 70 from the panel material 12. It may be a transparent film or a resin plate. Moreover, it is preferable to form the silica particle layer 71 also on the indoor side.

  According to the bearing wall 100 configured as described above, the panel material 12 is manufactured by FRP, and a plurality of grid-like ribs 28 are formed in the vertical direction and the horizontal direction. The bearing wall 100 having performance can be provided.

  Further, the load bearing wall 100 is configured by arranging the meshed glass plates 16 and 17 with predetermined gaps 78 and 82 with respect to the inner meshed glass plates 72 and 74, so that the load bearing wall having fireproof performance, That is, it is possible to provide the load bearing wall 100 suitable for the 30-minute fireproof structure and the semi-fireproof 45-minute structure. Furthermore, since heat is released to the back surfaces of the meshed glass plates 16 and 17 by the gaps 78 and 82, the temperature rise of the meshed glass plates 16 and 17 is suppressed, and the meshed glass plates 16 and 17 are softened or melted. Is the same level as when using netted glass alone.

  On the other hand, when FRP is used as the material of the panel material 12, it is preferable that the material constituting the FRP is filled with a hydrate such as aluminum hydroxide so that it does not easily burn.

  The silica particles 70 preferably have a hollow porous structure such as activated carbon at the nano level for heat resistance. However, the silica particles 70 having the above-described structure have a property of being crushed when the temperature is 600 ° C. or higher. A silica particle layer 71 having a predetermined thickness is provided in order to prevent a gap from being generated in the openings 30 of the lattice of the panel material 12 due to a reduction in volume caused by the silica particles 70 being crushed. The silica particle layer 71 fills the gaps between the silica particles of the panel material 12 with the silica particles of the silica particle layer 71, suppresses the temperature transmission of the panel material 12, and delays the temperature rise of the panel material 12. Further, as shown in FIG. 8, a tank 73 of silica particles 70 is formed above the upper end portion of the panel material 12, and a predetermined amount of silica particles 70 is stored in the tank 73. A gap is prevented from flowing into the panel material 12 sequentially from 73 through the silica particle layer 71.

  FIG. 9 is an enlarged cross-sectional view of a main part of the load bearing wall 100 shown in FIG. 8, and a to e showing respective dimensions are described. a is the thickness of the panel material 12 and 30 mm, b is the thickness of the silica particle layer 71 and 10 mm, c is the thickness of the inner glass plates 72 and 74 6.8 mm, d is the gap 78, 80 and 10 mm, and e is the thickness of the outer meshed glass plates 16 and 17 and is 6.8 mm. That is, the total wall thickness of the bearing wall 100 is 87.2 mm. In addition, although this dimension is an example, it is the load-bearing wall 10 which adapts to a 30-minute fireproof structure, a semi-fireproof 45-minute structure, etc. based on the Building Standard Law enforcement order.

  The load bearing walls 10 and 100 shown in FIGS. 1 to 9 are load bearing walls adapted to the quasi-fire resistant 45 minute structure, but in the case of adapting only to the 30 minute fire resistant structure, alumina disposed on the indoor side. What is necessary is just to make it the load-bearing wall of the structure which eliminated the blanket 15 and the glass plate 17 with a net | network. That is, in the case of the load-bearing wall 10 shown in FIG. 6, the structure may be such that the alumina blanket 15 and the netted glass plate 17 are eliminated. In the case of the load-bearing wall 100 shown in FIG. A structure without the plate 17 may be used.

  The bearing wall of the present invention can be used as an outer wall of a small-scale building made of wood, a partition wall, a roof, and a wall of a building such as a reinforced concrete structure.
