[0004] In the fire-resistant exterior wall structure of Patent Document 1, the contact area between the exterior wall material and the spacer is small (contact at a point), which can reduce the strength of the wall and make it difficult to position the fixing devices for the wall material.

[0010] The wall material application method and laminate of the present invention will be described below with reference to the drawings. The drawings described in the following embodiments are schematic, and the ratios of the sizes and thicknesses of the components in the drawings do not necessarily reflect the actual dimensional ratios. The following embodiments are merely a portion of various embodiments of the present invention. The following embodiments can be modified in various ways depending on the design, etc., as long as the object of the present invention can be achieved.

[0011] (First embodiment) 1. Overview In the method for installing a wall material according to this embodiment, wall material 1 and fire-resistant sheet 2, which expands at a predetermined temperature, are arranged opposite each other, and melting element 3, which melts at a temperature equal to or lower than the predetermined temperature and between 50°C and 200°C, is interposed between wall material 1 and fire-resistant sheet 2. This allows melting element 3 to melt before fire-resistant sheet 2 expands, and allows fire-resistant sheet 2 to expand into the space formed after melting element 3. This makes it easier for fire-resistant sheet 2 to expand.

[0012] In wall structures that include wall materials and fire-resistant sheets, it is sometimes impossible to provide a gap between the wall materials and the fire-resistant sheets, and the two are stacked in close contact. This construction method is particularly used in interior wall structures that use interior wall materials, in order to avoid increasing the thickness of the interior wall so as not to narrow the room space. However, with construction methods that tightly connect the wall materials and the fire-resistant sheets, it is difficult to ensure sufficient expansion space for the fire-resistant sheets, and the fire-resistant sheets may not have enough expansion space to fully demonstrate their fire-resistant effect.

[0013] Therefore, the inventors have developed a method to maintain the fire resistance of the wall structure by using a melting material between the wall material 1 and the fireproof sheet 2. In the event of a fire, the melting material 3 melts, creating space for the fireproof sheet 2 to expand. Note that the melting material 3 needs to have a certain level of strength when it is installed.

[0014] 2.Details 1 shows a laminate 100 of this embodiment. The laminate 100 is a wall structure, and is particularly suitable for use in the structure of an interior wall installed inside a building.

[0015] The laminate 100 comprises a wall material 1, a fireproof sheet 2, and a melting member 3. The laminate 100 also comprises a base surface material 4 and a structural material 5.

[0016] The wall material 1 is a finishing material placed on the outermost layer of the laminate 100, and examples thereof include ceramic siding materials and metal siding materials. The wall material 1 is formed in a substantially plate shape. The wall material 1 shown in FIG. 1 is made of metal, and uses spandrels formed by repeatedly bending a metal plate such as a steel plate (plated steel plate, painted steel plate, etc.) in the thickness direction to form an uneven (corrugated) cross-sectional shape. When the laminate 100 is an interior wall structure, the wall material 1 is an interior wall material.

[0017] The fire-resistant sheet 2 is a member that foams and expands due to heat during a fire. The fire-resistant sheet 2 does not foam or expand at room temperature, but is formed into a sheet before a fire breaks out (such as during installation). The thickness of the fire-resistant sheet 2 is preferably 0.1 mm to 5 mm, more preferably 0.3 mm to 3 mm, and even more preferably 0.4 mm to 1 mm. The fire-resistant sheet 2 preferably expands so that its volume after foaming is 10 to 30 times its unfoamed volume. The fire-resistant sheet 2 foams and expands at a predetermined temperature. This predetermined temperature is higher than the melting temperature of the melting element 3. As a result, the fire-resistant sheet 2 foams and expands after the melting element 3 melts. The predetermined temperature is preferably 200°C to 600°C. If the expansion temperature of the fire-resistant sheet 2 is lower than this temperature range, the fire-resistant sheet 2 may expand under normal conditions before a fire breaks out. If the expansion temperature of the fire-resistant sheet 2 is higher than the above temperature range, the fire-resistant sheet 2 may not expand when a fire breaks out. The predetermined temperature is more preferably 250°C or higher and 550°C or lower, and is preferably, for example, about 250°C.

[0018] The fire-resistant sheet 2 contains a synthetic resin, a polyhydric alcohol, and a flame-retardant foaming agent. Examples of synthetic resins include melamine resin, acrylic resin, alkyd resin, vinyl chloride resin, vinyl acetate resin, urethane resin, epoxy resin, silicone resin, polyester resin, polyolefin / vinyl acetate resin, vinyl acetate / versatic acid vinyl ester copolymer resin, vinyl acetate / polyolefin resin, vinyl acetate / versatic acid / acrylic resin, vinyl acetate / acrylic copolymer resin, acrylic / styrene copolymer resin, and polybutadiene resin. Examples of polyolefins include polyethylene.

[0019] Examples of polyhydric alcohols include pentaerythritol, dipentaerythritol, tripentaerythritol, and polypentaerythritol.

[0020] As the flame-retardant blowing agent, phosphates such as ammonium phosphate, ammonium polyphosphate, melamine phosphate, melamine polyphosphate, aluminum polyphosphate, and magnesium polyphosphate phosphate are preferably used, but examples thereof include sulfamates (ammonium sulfamate, etc.), borates (ammonium borate, etc.), and expandable graphite.

[0021] The content ratio of the synthetic resin, polyhydric alcohol and flame-retardant foaming agent in the fire-resistant sheet 2 is preferably 10 to 50 parts by mass of the polyhydric alcohol and 50 to 200 parts by mass of the flame-retardant foaming agent per 100 parts by mass of the synthetic resin.

[0022] The melting element 3 is a component that melts due to heat during a fire. The melting element 3 does not melt at room temperature, and is formed into a predetermined shape before a fire breaks out (such as during construction). The melting element 3 is preferably formed in a flat plate (board). That is, it is preferable that the melting element 3 has two surfaces (surfaces) that face each other in the thickness direction formed flat. This makes the two surfaces of the melting element 3 that face each other in the thickness direction a continuous flat surface, and by using a melting element 3 with a surface that is less uneven, the workability of the melting element 3 is improved.

[0023] The material of the melting member 3 is preferably a synthetic resin, which makes the melting member 3 easily meltable by heat in the event of a fire. Examples of synthetic resins include vinyl-based materials such as polyvinyl chloride (PVC) and polyvinyl alcohol (PVA), polystyrene-based materials such as polystyrene (PS), styrene-acrylonitrile copolymer (AS), and styrene-butadiene-acrylonitrile copolymer (ABS), polyolefin-based materials such as polyethylene (PE) and polypropylene (PP), and other thermoplastic resins.

[0024] The material of the melting element 3 is preferably a foamed resin. This allows the melting element 3 to have higher thermal insulation properties than when it is made of a non-foamed resin, making it easier to build a laminate (wall structure) with high thermal insulation performance. In addition, the melting element 3 made of a foamed resin is lighter than when it is made of a non-foamed resin, improving workability.

[0025] The melting temperature of the melting element 3 is lower than the temperature (predetermined temperature) at which the fire-resistant sheet 2 expands. As a result, the fire-resistant sheet 2 foams and expands after the melting element 3 melts. The melting temperature of the melting element 3 is 50°C or higher and 200°C or lower. If the melting temperature of the melting element 3 is lower than 50°C, the melting element 3 may soften and melt under normal circumstances before a fire breaks out, and if the melting temperature of the melting element 3 exceeds 200°C, the fire-resistant sheet 2 may not melt before expanding.

[0026] The melting temperature of the melting member 3 is preferably 70°C or higher and 170°C or lower, and more preferably 70°C or higher and 130°C or lower. The melting temperature of polypropylene is approximately 168°C. Similarly, extruded polystyrene foam (Styrofoam (registered trademark)) has a melting temperature of approximately 170°C, polyethylene has a melting temperature of 95°C or higher and 140°C or lower, and polystyrene has a melting temperature of 100°C or lower (70°C or higher and 90°C or lower).

[0027] The melting member 3 has a compressive strength of 50 kN / m as measured in accordance with JIS K 7220. 2 It is preferable that the compressive strength of the melting member 3 is 50 kN / m or more. This allows the wall material 1 to be placed and held on the surface of the melting member 3. 2 If the compressive strength is less than 50 kN / m, the melting member 3 may be depressed and unable to be supported when the wall material 1 is pressed. 2 The melting member 3 has a compressive strength of 80 kN / m, which is equivalent to JIS No. 4 as specified in JIS A 9511:2017. 2 It is preferable that the compressive strength is 160kN / m or more, which is equivalent to JIS No. 2. 2 The upper limit of the compressive strength of the melting part 3 is 1000 kN / m or more.2 It is preferable that:

[0028] By having the above-mentioned constant strength of the melting member 3, dents (compression) are less likely to occur on the wall surface formed by the wall material 1, and the shock absorption of the wall is also improved. Also, if the melting member 3 is a soft material such as a sponge, it will not be able to maintain a constant strength for installation.

[0029] The material of the melting member 3 is preferably expanded polystyrene. This makes it easy to form a melting member 3 with the desired heat insulating properties, compressive strength, and melting temperature. Among the expanded polystyrenes, it is preferable to form the melting member 3 from bead-method polystyrene foam (EPS), which is easy to manufacture. Specifically, the melting member 3 of EPS has a melting temperature of 170°C, softens at 90-120°C, and has a 0.5 mm displacement load in compressive strength of 2.8 N / cm. 2 , 1.0mm displacement load is 5.45N / cm 2 The foaming ratio is 30 times and the density is 50 kg / m 3 The thickness of the melting element 3 is preferably 20 mm or more and 25 mm or less, which makes it easier to form a space large enough for the fire-resistant sheet 2 to expand after the melting element 3 melts.

[0030] The base surface material 4 is a flat plate-like member that serves as a base for attaching the fire-resistant sheet 2, the melting member 3, and the wall material 1. The base surface material 4 is preferably made of a highly fire-resistant (non-combustible) material, such as gypsum board, calcium silicate board, or non-combustible plywood.

[0031] Structural members 5 are members that make up the framework of a building. Examples of structural members 5 include pillars (through columns), partition posts, pipe columns, and cross members (beams, girders, and girder beams). Because the structure shown in FIG. 1 is a steel-framed framework, metal members such as C-shaped steel can be used for structural members 5. In addition to C-shaped steel, L-shaped steel, H-shaped steel, channel steel, I-shaped steel, square steel pipes, and the like can also be used as structural members 5.

[0032] The laminate 100 of this embodiment can be formed by sequentially installing each component starting from the structural member 5 toward the wall member 1 (forward). The base surface member 4 is disposed in front of the structural members 5 and is fixed to each structural member 5 with fasteners such as nails or screws. The fireproof sheet 2 is disposed so as to contact the front surface of the base surface member 4 (the surface opposite to the surface facing the structural members 5) and is fixed with fasteners such as nails, screws, or tackers. The fireproof sheet 2 is disposed so as to cover almost the entire front surface of the base surface member 4. The melting element 3 is disposed so as to contact the front surface of the fireproof sheet 2 (the surface opposite to the surface facing the base surface member 4) and is fixed with fasteners such as nails or screws. The rear surface of the melting element 3 is disposed so as to contact almost the entire front surface of the fireproof sheet 2. The wall member 1 is disposed so as to contact the front surface of the melting element 3 (the surface opposite to the surface facing the fireproof sheet 2) and is fixed with fasteners 6 such as nails or screws. The wall material 1 is provided so as to cover almost the entire front surface of the melting element 3. The fasteners 6 are driven into the front surface of the wall material 1 (the surface opposite to the surface facing the melting element 3), penetrating through the wall material 1, the melting element 3, the fireproof sheet 2, and the base surface material 4, and into the structural material 5. In other words, even if the melting element 3 melts, the wall material 1 is supported by the structural material 5 by the fasteners 6, making it less likely to fall off. Furthermore, because the structural material 5 into which the fasteners 6 are driven is larger than the spacer of Patent Document 1, the positioning of the fasteners 6 that secure the wall material 1 can be easily performed.

[0033] In the laminate 100 of this embodiment, the melting member 3 is interposed between the wall material 1 and the fire-resistant sheet 2, which are opposed in the front-to-rear direction. Therefore, when the melting member 3 melts and is almost completely removed by the heat of a fire, a space (void) is formed between the wall material 1 and the fire-resistant sheet 2. Therefore, the fire-resistant sheet 2 can foam and expand due to the heat of a fire in the space formed by the melting member 3, making the fire-resistant sheet 2 more likely to expand. The expanded fire-resistant sheet 2 is flame-resistant and has an increased thickness, resulting in excellent heat insulation. This makes it difficult for the fire resistance of the laminate 100 to decrease in the event of a fire. Furthermore, the increased thickness of the fire-resistant sheet 2 can contact the rear surface of the wall material 1 to support the wall material 1, making it less likely for the wall material 1 to fall off.

[0034] Furthermore, since the melting element 3 has a surface (front surface) that is in continuous contact with the wall material 1 and another surface (rear surface) that is in continuous contact with the fire-resistant sheet 2, the entire wall material 1 can be supported by the continuous surface of the melting element 3, allowing for stable construction of the wall material 1. Furthermore, since the melting element 3 is in contact with the entire wall material 1 over a larger area than the spacer of Patent Document 1, the strength of the entire wall can be increased.

[0035] (Second embodiment) As shown in Fig. 2, the laminate 100A according to this embodiment differs from the laminate 100 according to the first embodiment in the configuration of the wall material 1, its fixing structure, and the structural material 5. Hereinafter, the same components as those in the first embodiment will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The configuration described in the second embodiment can be applied in appropriate combination with the configuration described in the first embodiment.

[0036] The wall material 1 is formed of a ceramic plate-like member. For example, a ceramic siding material can be used as the wall material 1.

[0037] In this embodiment, a plurality of furring strips 7 and a plurality of fasteners 8 are provided for constructing the wall material 1. The plurality of furring strips 7 are provided on the front surface of the melting member 3 and are fixed to the structural material 5 with fasteners 6 such as nails or screws. Each furring strip 7 is arranged parallel to the longitudinal direction of the structural material 5. Each furring strip 7 is formed into a long length from a metal member (shaped steel or aluminum member) or a wooden member (such as a square timber).

[0038] The multiple fasteners 8 are each arranged on the front surface of each furring strip 7. Each fastener 8 is fixed to each furring strip 7 with fixings such as screws or nails. Each fastener 8 is made of metal and is formed by processing a metal plate such as a steel plate.

[0039] Each fastener 8 has a portion for hooking the wall material 1, and by hooking the upper and lower ends of the wall material 1 onto this hooking portion, multiple wall materials 1 are positioned in front of the melting member 3.

[0040] Furthermore, since the laminate 100A of this embodiment is a wall structure of a wooden building, the structural member 5 is formed of wooden timber.

[0041] In the laminate 100A of this embodiment, the melting element 3, furring strips 7, and fasteners 8 are interposed between the wall material 1 and the fireproof sheet 2, which are opposed in the front-to-back direction. Therefore, when the melting element 3 melts and is almost completely removed due to the heat of a fire, a space (void) is formed between the wall material 1 and the fireproof sheet 2. Therefore, the fireproof sheet 2 can foam and expand due to the heat of a fire, filling the space formed by the melting element 3. The increased thickness of the fireproof sheet 2 allows it to contact the rear surface of the furring strips 7 and support the furring strips 7 and fasteners 8, preventing the wall material 1 from falling off. Because the thickness of the fasteners 6 is sufficiently small compared to the area of ​​the melting element 3, the thickness of the fasteners 6 can be freely set, and a member for holding the furring strips 7 and fasteners 8 may be present together with the fasteners 6. Furthermore, because the furring strips 7 contact the wall material 1 over a larger area than the spacer in Patent Document 1, the strength of the entire wall can be increased.

[0042] (Third embodiment) As shown in Fig. 3, the laminate 100B according to this embodiment differs from the laminate 100A according to the second embodiment in the fixing structure of the wall material 1. Hereinafter, the same components as those in the first and second embodiments will be denoted by the same reference numerals and will not be described as appropriate. The components described in the third embodiment can be applied in appropriate combination with the components described in the first and second embodiments.

[0043] The laminate 100B of this embodiment has a structure in which the furring strips 7 are removed from the laminate 100A of the second embodiment. Therefore, the fasteners 8 are not fixed to the furring strips 7. A plurality of fasteners 8 are provided on the front surface of the melting member 3, and are fixed to the structural material 5 with fasteners 6 such as nails or screws.

[0044] In the laminate 100B of this embodiment, the melting member 3 and fastener 8 are interposed between the wall material 1 and the fire-resistant sheet 2, which face each other in the front-to-back direction. Therefore, when the melting member 3 melts and is almost completely removed by the heat of a fire, a space (void) is formed between the wall material 1 and the fire-resistant sheet 2. Therefore, the fire-resistant sheet 2 can foam and expand due to the heat of a fire in the space formed by the melting member 3, making it easier for the fire-resistant sheet 2 to expand. The fire-resistant sheet 2, which has increased in thickness, can contact the rear surface of the fastener 8 and support it, making it less likely for the wall material 1 to fall off.

[0045] (Fourth embodiment) As shown in Fig. 4, the laminate 100C according to this embodiment differs from the laminate 100A according to the second embodiment in the fixing structure of the wall material 1. Hereinafter, the same components as those in the first to third embodiments will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The components described in the fourth embodiment can be applied in appropriate combination with the components described in the first to third embodiments.

[0046] The laminate 100C of this embodiment has a structure in which the fasteners 8 are removed from the laminate 100A of the second embodiment. Therefore, the wall material 1 is not fixed to the fasteners 8. Multiple furring strips 7 are provided on the front surface of the melting member 3 and are fixed to the structural material 5 with fasteners 6 such as nails or screws. Multiple wall materials 1 are arranged in front of the furring strips 7 by fixing their upper and lower ends to the furring strips 7 with the fasteners 6.

[0047] In the laminate 100C of this embodiment, the melting element 3 and the furring strips 7 are interposed between the wall material 1 and the fire-resistant sheet 2, which face each other in the front-to-back direction. Therefore, when the melting element 3 melts and is almost completely removed by the heat of a fire, a space (void) is formed between the wall material 1 and the fire-resistant sheet 2. Therefore, the fire-resistant sheet 2 can foam and expand due to the heat of a fire in the space formed by the melting of the melting element 3, making it easier for the fire-resistant sheet 2 to expand. The fire-resistant sheet 2, which has increased in thickness, can contact the rear surface of the furring strips 7 to support the furring strips 7, making it less likely for the wall material 1 to fall off.

[0048] (Fifth embodiment) As shown in Fig. 5, the laminate 100D according to this embodiment differs from the laminate 100A according to the second embodiment in the fixing structure of the wall material 1. Hereinafter, the same components as those in the first to fourth embodiments will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The components described in the fifth embodiment can be applied in appropriate combination with the components described in the first to fourth embodiments.

[0049] The laminate 100D of this embodiment has a structure in which the furring strips 7 and fasteners 8 are removed from the laminate 100A of the second embodiment. Therefore, the wall materials 1 are not fixed to the furring strips 7 and fasteners 8. Multiple wall materials 1 are provided on the front surface of the melting member 3 and fixed to the structural material 5 with fasteners 6 such as nails or screws. Multiple wall materials 1 are arranged in front of the melting member 3 by fixing their upper and lower ends to the structural material 5 with the fasteners 6.

[0050] In the laminate 100D of this embodiment, the melting member 3 is interposed between the wall material 1 and the fire-resistant sheet 2, which are opposed in the front-to-rear direction. Therefore, when the melting member 3 melts and is almost completely removed by the heat of a fire, a space (void) is formed between the wall material 1 and the fire-resistant sheet 2. Therefore, the fire-resistant sheet 2 can foam and expand due to the heat of a fire in the space formed by the melting member 3, making it easier for the fire-resistant sheet 2 to expand. The fire-resistant sheet 2, which has increased in thickness, can contact the rear surface of the wall material 1 and support the wall material 1, making it less likely for the wall material 1 to fall off.

[0051] (Sixth embodiment) As shown in Fig. 6, the laminate 100E according to this embodiment differs from the laminate 100A according to the second embodiment in the structural material 5. Hereinafter, the same components as those in the first to fifth embodiments will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The components described in the sixth embodiment can be applied in appropriate combination with the components described in the first to fifth embodiments.

[0052] The laminate 100E of this embodiment represents the wall structure of a steel-framed building. Therefore, as with the structural members 5 of the first embodiment, metal members such as shaped steel are used as the structural members 5. The other configurations are the same as those of the second embodiment.

[0053] Seventh embodiment 7, the laminate 100F according to this embodiment differs from the laminate 100B according to the third embodiment in the structural material 5. Hereinafter, the same components as those in the first to sixth embodiments will be denoted by the same reference numerals, and the description thereof will be omitted as appropriate. The components described in the seventh embodiment can be applied in appropriate combination with the components described in the first to sixth embodiments.

[0054] The laminate 100F of this embodiment represents the wall structure of a steel-framed building. Therefore, as in the structural members 5 of the first embodiment, metal members such as shaped steel are used as the structural members 5. The other configurations are the same as those of the third embodiment.

[0055] (Eighth embodiment) 8, the laminate 100G according to this embodiment differs from the laminate 100C according to the fourth embodiment in the structural material 5. Hereinafter, the same components as those in the first to seventh embodiments will be denoted by the same reference numerals and will not be described as appropriate. The components described in the eighth embodiment can be applied in appropriate combination with the components described in the first to seventh embodiments.

[0056] The laminate 100G of this embodiment represents the wall structure of a steel-framed building. Therefore, as with the structural members 5 of the first embodiment, metal members such as shaped steel are used as the structural members 5. The other configurations are the same as those of the fourth embodiment.

[0057] (Ninth embodiment) 9, the laminate 100H according to this embodiment differs from the laminate 100D according to the fifth embodiment in the structural material 5. Hereinafter, the same components as those in the first to eighth embodiments will be denoted by the same reference numerals and will not be described as appropriate. The components described in the ninth embodiment can be applied in appropriate combination with the components described in the first to eighth embodiments.

[0058] The laminate 100H of this embodiment represents the wall structure of a steel-framed building. Therefore, as in the structural member 5 of the first embodiment, metal members such as shaped steel are used as the structural member 5. The other configurations are the same as those of the fifth embodiment.

[0059] (summary) The first aspect is a method for constructing a wall material 1, in which the wall material 1 and a fire-resistant sheet 2 that expands at a predetermined temperature are arranged opposite each other, and a melting member 3 that melts at a temperature equal to or lower than the predetermined temperature and between 50°C and 200°C is interposed between the wall material 1 and the fire-resistant sheet 2.

[0060] According to this embodiment, the melting element 3 can be melted before the fire-resistant sheet 2 expands, and the fire-resistant sheet 2 can expand into the space formed after the melting element 3 melts, making it easier for the fire-resistant sheet 2 to expand. In addition, since the melting element 3 is interposed between the wall material 1 and the fire-resistant sheet 2, the melting element 3 can support the entire wall material 1, which tends to improve the strength of the entire wall.

[0061] The second aspect is a method for installing the wall material 1 described in the first aspect, in which the melting member 3 has a surface that is in continuous contact with the wall material 1 and another surface that is in continuous contact with the fire-resistant sheet 2.

[0062] According to this embodiment, the melting member 3 can come into contact with the fireproof sheet 2 and the wall material 1 over a wide area, making it easier for the wall material 1 to be supported by the melting member 3 and for the wall material 1 to be installed.

[0063] The third aspect is the method for applying the wall material 1 of the first or second aspect, in which the material of the melting member 3 is a foamed resin.

[0064] According to this embodiment, the weight of the melting member 3 can be reduced, making construction easier, and the heat insulating properties of the melting member 3 are improved, making it easier to form a laminate 100 with high heat insulating properties.
