Description

[Technical Field]

[0001] The present invention relates to a method for constructing an exterior wall, and more particularly to a method for constructing an exterior wall that is suitable for reducing the amount of work involved in constructing an exterior wall. [Background technology]

[0002] BACKGROUND ART Conventionally, as exterior wall panels for buildings, highly rigid plate-like exterior wall panels, such as precast concrete panels and ALC (Autoclaved Lightweight Aerated Concrete), have been known (Patent Document 1).

[0003] Meanwhile, conventionally, there is known a technique for constructing a building using different materials for the exterior walls and flooring. In this case, gaps inevitably occur between the flooring and the exterior walls. There are various reasons for the occurrence of gaps, but the main reason is that when a building is shaken by an earthquake or wind, different materials will shake in different ways, which could result in damage, and gaps are provided to prevent this. These gaps must be filled later with mortar or a non-combustible material from the standpoint of fire resistance, soundproofing, etc. (Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-255250 [Patent Document 2] Japanese Patent Application Publication No. 2024-90796 Summary of the Invention [Problem to be solved by the invention]

[0005] However, in the technology described in Patent Document 1, since the material is a highly rigid plate, if any interference occurs, it will be necessary to re-examine the installation position or make adjustments such as processing the exterior wall panel.

[0006] Furthermore, the technique described in Patent Document 2 requires interlayer sealing work to seal gaps. Therefore, the present invention has been made with a focus on the unresolved problems of the conventional technology, and aims to provide a method of constructing exterior walls that is suitable for reducing the work required for constructing exterior walls. [Means for solving the problem]

[0007] [Invention 1] In order to achieve the above object, the exterior wall panel of Invention 1 is an exterior wall panel to be attached to a structural body to form an exterior wall, and is made by laminating an exterior material that forms the outdoor surface and an insulating material that forms the indoor surface, the exterior material being made of steel and the insulating material being made of an elastic material.

[0008] With this configuration, the insulation material on the indoor side is elastic, so when interference occurs, it can be pressed against the structural frame.

[0009] [Invention 2] Furthermore, the exterior wall panel of Invention 2 is the exterior wall panel of Invention 1, wherein the insulating material is formed by stacking a first insulating material formed by connecting a plurality of plate-shaped elastic materials in the surface direction and a second insulating material formed by connecting a plurality of plate-shaped elastic materials in the surface direction, with the joints of the first insulating material and the joints of the second insulating material offset from each other.

[0010] With this configuration, the joints of the first insulating material and the joints of the second insulating material are misaligned, so heat, moisture, etc. that enter through the joints of the first insulating material are blocked by the second insulating material, and heat, moisture, etc. that enter through the joints of the second insulating material are blocked by the first insulating material.

[0011] [Invention 3] Furthermore, the exterior wall panel of Invention 3 is the exterior wall panel of Invention 2, in which a non-flammable seal is provided on the first insulating material and the second insulating material on the exterior material side so as to cover the joints.

[0012] With this configuration, a non-flammable seal is provided in the joints of the insulation material on the exterior material side, so that heat entering from the exterior material side through the joints of the first insulation material or the second insulation material is blocked by the non-flammable seal.

[0013] [Invention 4] Furthermore, the exterior wall panel of Invention 4 is the exterior wall panel of Invention 1, in which a surface material is provided on the indoor side of the heat insulating material.

[0014] [Invention 5] Furthermore, the exterior wall panel of Invention 5 is the exterior wall panel of Invention 4, wherein the surface material is formed by laminating an aluminum foil having a thickness of 7 to 50 μm and a poly sheet having a thickness of 12 to 50 μm.

[0015] [Invention 6] On the other hand, in order to achieve the above object, the exterior wall construction method of Invention 6 includes a first step of installing the exterior materials that make up the exterior wall and the flooring materials that make up the floor, leaving gaps between them, and a second step of installing an insulating material made of an elastic material along the exterior materials so that the gaps are filled.

[0016] [Invention 7] Furthermore, the exterior wall construction method of Invention 7 is the exterior wall construction method of Invention 6, wherein the first step is to install the exterior material between pillar materials, and the second step is to install the insulation material along the exterior material so as to cover one or both of the pillar materials and fill the gap. [Effects of the Invention]

[0017] As explained above, according to the exterior wall panel of Invention 1, the insulation material on the indoor side is elastic, so when there is interference, it can be pressed against the structural frame, reducing the need for gap sealing work. Therefore, compared to conventional methods, the amount of work required for exterior wall construction can be reduced. In addition, because the exterior material is steel, the insulation material can be firmly attached.

[0018] Furthermore, according to the exterior wall panel of Invention 2, the joints of the first insulating material and the joints of the second insulating material are misaligned, thereby reducing the possibility of heat, moisture, etc. entering through the joints.

[0019] Furthermore, according to the exterior wall panel of Invention 3, a non-flammable seal is provided in the joints of the insulating material on the exterior material side, thereby reducing the possibility of heat entering through the joints from the exterior material side.

[0020] Furthermore, according to the exterior wall panel of Invention 4, a surface material is provided on the indoor side of the insulation material, thereby reducing the possibility of tearing or damage, etc., and the possibility of heat, moisture, etc., entering.

[0021] Furthermore, the exterior wall panel of Invention 5 can achieve both abrasion resistance and flexibility.

[0022] On the other hand, according to the exterior wall construction method of Invention 6, since the insulating material is elastic, it can be pressed down when there is interference, and there is less need for gap sealing work. Therefore, the work required for exterior wall construction can be reduced compared to conventional methods.

[0023] Furthermore, according to the exterior wall construction method of Invention 7, by installing elastic heat insulating material on the pillars as well as the exterior material, there is less need to carry out separate fireproofing work on the pillars. [Brief explanation of the drawings]

[Figure 3] 2 is a horizontal cross-sectional view of the exterior wall panel 100 taken along line BB' in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0025] [First embodiment] A first embodiment of the present invention will be described below, with Figs. 1 to 3 showing the present embodiment.

[0026] First, the configuration of this embodiment will be described. FIG. 1 is a perspective view of an exterior wall panel 100. Fig. 2 is a vertical cross-sectional view of the exterior wall panel 100 taken along line AA' in Fig. 1. Fig. 2(b) is an enlarged view of the dotted line portion in Fig. 2(a).

[0027] Fig. 3 is a horizontal cross-sectional view of the exterior wall panel 100 taken along line BB' in Fig. 1. Fig. 3(b) is an enlarged view of the dotted line portion in Fig. 3(a).

[0028] The exterior wall panel 100 is a panel to be attached to a structural frame to form an exterior wall, and is used, for example, as a curtain wall.

[0029] 1 to 3, the exterior wall panel 100 is composed of a laminated panel material formed by laminating, in that order, an exterior cladding material 1, an exterior insulating material 2, an interior insulating material 3, and a facing material 4. The laminated panel material is fixed between a left frame 5a and a right frame 5b.

[0030] The exterior material 1 is made of steel material. For example, the steel material may have a thickness of 1.5 mm or more.

[0031] The external heat insulating material 2 is composed of a plurality of rectangular plate-shaped elastic materials 2a connected in the planar direction. The elastic materials 2a may be, for example, a fire-resistant material such as rock wool with a colored nonwoven fabric applied to the surface.

[0032] The internal heat insulating material 3 is formed by connecting a plurality of rectangular plate-shaped elastic materials 3a in the planar direction. The elastic materials 3a may be the same as the elastic materials 2a, or a different fire-resistant material from the elastic materials 2a.

[0033] The external insulation material 2 and the internal insulation material 3 are stacked such that the joints 2b (hereinafter referred to as "joints of the external insulation material 2") which are the surface-direction connecting portions of the elastic material 2a and the joints 3b (hereinafter referred to as "joints of the internal insulation material 3") which are the surface-direction connecting portions of the elastic material 3a are offset from each other. The vertical joints 2b of the external insulation material 2 and the vertical joints 3b of the internal insulation material 3 are spaced apart, for example, by 100 mm or more. The horizontal joints 2b of the external insulation material 2 and the horizontal joints 3b of the internal insulation material 3 are spaced apart, for example, by 100 mm or more.

[0034] The external insulation material 2 is fixed to the exterior packaging material 1 by fasteners 2c. The fasteners 2c are made of stud pins, washers, etc., and fasten the external insulation material 2 and the exterior packaging material 1 by penetrating them in the thickness direction. The vertical spacing between the fasteners 2c is set to be, for example, 600 mm or less. The horizontal spacing between the fasteners 2c is set to be, for example, 600 mm or less.

[0035] The inner insulation material 3 is fixed to the exterior packaging material 1 by fasteners 3c. The fasteners 3c are made of stud pins, washers, etc., and fasten the inner insulation material 3, the outer insulation material 2, and the exterior packaging material 1 by penetrating them in the thickness direction. The vertical spacing between the fasteners 3c is set to be, for example, 450 mm or less. The horizontal spacing between the fasteners 3c is set to be, for example, 450 mm or less.

[0036] A non-combustible seal 2d is provided at the horizontal joints 2b of the external heat insulating material 2 so as to cover the joints 2b.

[0037] The surface material 4 is formed by laminating, for example, aluminum foil, poly sheet, and nonwoven fabric. Increasing the thickness of each material of the aluminum foil, poly sheet, and nonwoven fabric improves abrasion resistance, but it also becomes hard and loses elasticity. Therefore, to achieve both abrasion resistance and elasticity, it is preferable to use an aluminum foil with a thickness of 7 to 50 μm and a poly sheet with a thickness of 12 to 50 μm. More preferably, the aluminum foil has a thickness of 7 μm, the poly sheet has a thickness of 12 μm, and the nonwoven fabric has a thickness of 15 g / m. 2 The surface material 4 can further be made of a moisture-proof material, which makes it difficult for moisture inside to escape and improves fire resistance.

[0038] Next, the construction method of this embodiment will be described. The floor and other structural components are constructed. After that, multiple exterior wall panels 100 are attached to the structural component to construct the exterior wall. In this process, the insulation materials 2 and 3, which form the indoor surface, are elastic, so they can be pressed against the structural component when they interfere with each other. Then, because the joints 2b and 3b are misaligned, heat, moisture, etc. that penetrate through the joint 2b of the exterior insulation material 2 are blocked by the interior insulation material 3, and heat, moisture, etc. that penetrate through the joint 3b of the interior insulation material 3 are blocked by the exterior insulation material 2. In addition, because the exterior insulation material 2 is provided with a seal 2d, heat that penetrates through the joint 2b of the exterior insulation material 2 is blocked by the seal 2d.

[0039] Next, the effects of this embodiment will be described. In this embodiment, the exterior wall panel 100 is formed by laminating an exterior material 1 that forms the outdoor surface and insulating materials 2 and 3 that form the indoor surface, with the exterior material 1 being made of steel and the insulating materials 2 and 3 being made of elastic material.

[0040] This allows the insulation materials 2 and 3, which form the indoor surface, to be elastic, so that they can be pressed against the structural frame when they interfere, reducing the need for gap sealing work. This reduces the amount of work required for exterior wall construction compared to conventional methods.

[0041] Furthermore, since the exterior cladding material 1 is made of steel, the heat insulating materials 2 and 3 can be firmly attached. The heat insulating materials 2 and 3 are unlikely to fall off even in the event of a fire, and because they are firmly fixed, they are also resistant to vibration.

[0042] Furthermore, in this embodiment, the external heat insulating material 2 and the internal heat insulating material 3 are stacked such that the joints 2b of the external heat insulating material 2 and the joints 3b of the internal heat insulating material 3 are offset.

[0043] This reduces the possibility of heat, moisture, etc. penetrating through the joints 2b and 3b.

[0044] Furthermore, in this embodiment, the external heat insulating material 2 is provided with a non-combustible seal 2d so as to cover the joints 2b.

[0045] This reduces the possibility of heat entering from the exterior packaging material 1 side through the joint 2b.

[0046] Furthermore, in this embodiment, a surface material 4 is provided on the indoor side of the internal heat insulating material 3. As a result, if the exterior wall panel 100 interferes with other components, there is a possibility that the exterior wall panel 100 may tear or break when vibrated, but the surface material 4 can reduce the possibility of tearing or breakage, etc., and the possibility of heat, moisture, etc., entering.

[0047] Furthermore, in this embodiment, the surface material 4 is made by laminating an aluminum foil having a thickness of 7 to 50 μm and a poly sheet having a thickness of 12 to 50 μm.

[0048] This makes it possible to achieve both abrasion resistance and elasticity. Furthermore, in this embodiment, the steel material of the exterior packaging material 1 has a thickness of 1.5 mm or more.

[0049] This allows the heat insulating materials 2 and 3 to be attached more firmly. In this embodiment, the external heat insulating material 2 corresponds to the first heat insulating material of the second or third invention, and the internal heat insulating material 3 corresponds to the second heat insulating material of the second or third invention.

[0050] Second Embodiment Next, a second embodiment of the present invention will be described. Only the differences from the first embodiment will be described below, and a description of overlapping parts will be omitted.

[0051] First, the construction method of this embodiment will be described. In the first step, the floor and other structural components are constructed.

[0052] Next, in the second step, the exterior material 1 is installed with a certain gap provided between it and the floor material. Next, in the third step, a laminated insulation material formed by laminating an external insulation material 2, an internal insulation material 3, and a surface material 4 is installed along the exterior insulation material 1 so as to fill the gap between the exterior insulation material 1 and the floor material. Furthermore, when installing the exterior insulation material 1 between pillar materials, in the third step, the laminated insulation material is installed along the exterior insulation material 1 so as to cover one or both of the pillar materials and fill the gap between the exterior insulation material 1 and the floor material. In the laminated insulation material, the joints 2b of the external insulation material 2 and the joints 3b of the internal insulation material 3 are misaligned, and a seal 2d is provided on the external insulation material 2, as in the first embodiment.

[0053] Then, in the fourth step, the laminated thermal insulation material is fixed to the exterior packaging material 1 with fasteners 3c. Next, the effects of this embodiment will be described.

[0054] According to the construction method of this embodiment, the insulating materials 2 and 3 are elastic, so they can be pressed together when they interfere with each other, reducing the need for gap sealing work. Therefore, the amount of work required for exterior wall construction can be reduced compared to conventional methods.

[0055] When installing exterior cladding 1 between pillars, fire resistance may also be required for the pillars, so in the past it was necessary to carry out separate fireproofing work on the pillars. In contrast, according to the construction method of this embodiment, elastic heat insulating materials 2 and 3 are installed on the pillars along with the exterior cladding 1, thereby reducing the need for separate fireproofing work on the pillars.

[0056] [Modification] In the above first and second embodiments and their modifications, seals 2d are provided in the horizontal joints 2b of the external insulation material 2, but this is not limited to this, and seals 2d can be provided in the vertical joints 2b of the external insulation material 2, the horizontal joints 3b of the internal insulation material 3, or the vertical joints 3b of the internal insulation material 3.

[0057] Furthermore, in the first and second embodiments and their modifications, a two-layer structure is used as the heat insulating material, but the present invention is not limited to this, and a one-layer structure or a three-layer or more structure may be used.

[0058] Furthermore, in the first and second embodiments and their modifications, the external insulation material 2 is fixed to the exterior packaging material 1 with fasteners 2c, but this is not limiting, and the external insulation material 2 can also be fixed to the exterior packaging material 1 together with the internal insulation material 3 with fasteners 3c without using fasteners 2c. Similarly, when a structure of three or more layers is adopted, two or more layers can be fixed to the exterior packaging material 1 with a common fastener.

[0059] In the second embodiment and its modified example, in the third and fourth steps, a laminated insulation material formed by stacking external insulation material 2, internal insulation material 3, and surface material 4 is installed, and the laminated insulation material is fixed to exterior packaging material 1 with fasteners 3c. However, this is not limited to this. Alternatively, a method may be employed in which external insulation material 2 is installed along exterior packaging material 1, external insulation material 2 is fixed to exterior packaging material 1 with fasteners 2c, a laminated insulation material formed by stacking internal insulation material 3 and surface material 4 is installed along exterior packaging material 2 so as to fill the gap between the external insulation material 2 and the floor material, and the laminated insulation material is fixed to exterior packaging material 1 with fasteners 3c. Alternatively, a method may be employed in which external insulation material 2 is installed along exterior packaging material 1, external insulation material 2 is fixed to exterior packaging material 1 with fasteners 2c, internal insulation material 3 is installed along exterior packaging material 2 so as to fill the gap between the external insulation material 2 and the floor material, and internal insulation material 3 is fixed to exterior packaging material 1 with fasteners 3c, and surface material 4 is installed on internal insulation material 3.

[0060] Furthermore, the first and second embodiments and their modifications can be applied to each other.

[0061] Furthermore, the present invention is not limited to the first and second embodiments and their modifications, but can also be applied to other cases within the scope of the gist of the present invention. [Explanation of symbols]
