Description

Technical Field

[0001] The present invention relates to an outer wall panel, and particularly to an outer wall panel suitable for reducing the work of outer wall construction.

Background Art

[0002] Conventionally, as an outer wall panel of a building, for example, a rigid plate-shaped outer wall panel such as a precast concrete panel or an ALC (Autoclaved Lightweight aerated Concrete) is known (Patent Document 1).

[0003] On the other hand, conventionally, a technique of building the outer wall and the floor material of a building with different materials is known. In this case, a gap always occurs between the floor material and the outer wall. There are various reasons for the occurrence of the gap, but the major reason is that when the building sways due to an earthquake or wind, different materials sway differently and there is a risk of damage, so a gap is provided to prevent this. This gap needs to be filled with mortar or a non-combustible material later from the viewpoints of fire resistance, sound insulation, etc. (Patent Document 2).

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the technique described in Patent Document 1, since it is a rigid plate-shaped one, when something interfering occurs, re-verification of the construction position and adjustments such as processing of the outer wall panel are required.

[0006] In the technology described in Patent Document 2, it is necessary to perform an interlayer plugging work to fill the gap. Therefore, the present invention has been made by paying attention to such unsolved problems of the conventional technology, and an object thereof is to provide an outer wall panel suitable for reducing the work of outer wall construction.

Means for Solving the Problems

[0007] 〔Device 1〕 In order to achieve the above object, the outer wall panel of Device 1 is an outer wall panel for forming an outer wall by attaching it to a structural frame, and is formed by laminating an exterior material that becomes the outdoor surface and a heat insulating material that becomes the indoor surface. The exterior material is made of steel, and the heat insulating material is made of an elastic material.

[0008] With such a configuration, since the heat insulating material that becomes the indoor surface has elasticity, it can be pressed against the structural frame during construction at the time of interference.

[0009] 〔Device 2〕 Further, in the outer wall panel of Device 2, in the outer wall panel of Device 1, the heat insulating material is formed by connecting a plurality of plate-shaped elastic materials in the plane direction to form a first heat insulating material and a plurality of plate-shaped elastic materials in the plane direction. The second heat insulating material formed by connecting is laminated with the joints of the first heat insulating material and the joints of the second heat insulating material shifted.

[0010] With such a configuration, since the joints of the first heat insulating material and the joints of the second heat insulating material are shifted, heat, moisture, etc. that penetrate through the joints of the first heat insulating material are blocked by the second heat insulating material, and heat, moisture, etc. that penetrate through the joints of the second heat insulating material are blocked by the first heat insulating material.

[0011] 〔Device 3〕 Further, in the outer wall panel of Device 3, in the outer wall panel of Device 2, a non-combustible seal is provided on the side of the first heat insulating material and the second heat insulating material on the side of the exterior material so as to cover the joints.

[0012] With such a configuration, since a non-combustible seal is provided at the joints of the heat insulating material on the side of the exterior material, heat that penetrates through the joints of the first heat insulating material or the second heat insulating material from the side of the exterior material is blocked by the non-combustible seal.

[0013] 〔Device 4〕Furthermore, for the outer wall panel of Device 4, in the outer wall panel of Device 1, a surface material is provided on the indoor side of the heat insulating material.

[0014] 〔Device 5〕Furthermore, for the outer wall panel of Device 5, in the outer wall panel of Device 4, the surface material is formed by laminating an aluminum foil with a thickness of 7 to 50 [μm] and a poly sheet with a thickness of 12 to 50 [μm].

[0015] 〔Device 6〕On the other hand, in order to achieve the above object, the construction method of the outer wall of Device 6 includes a first step of installing an exterior material constituting the outer wall and a floor material constituting the floor with a gap therebetween, and a second step of installing a heat insulating material made of an elastic material along the exterior material so that the gap is filled.

[0016] 〔Device 7〕Furthermore, for the construction method of the outer wall of Device 7, in the construction method of the outer wall of Device 6, in the first step, the exterior material is installed between column members, and in the second step, the heat insulating material is installed along the exterior material so as to cover one or both of the column members and fill the gap.

Advantages of the Invention

[0017] As described above, according to the outer wall panel of Device 1, since the heat insulating material on the indoor surface has elasticity, it can be pressed against the structural frame during construction, and there is little need to perform gap filling work. Therefore, compared with the prior art, the work of outer wall construction can be reduced. In addition, since the exterior material is steel, the heat insulating material can be firmly attached.

[0018] Furthermore, according to the outer wall panel of Device 2, since the joints of the first heat insulating material and the joints of the second heat insulating material are displaced, the possibility of heat, moisture, etc. entering through the joints can be reduced.

[0019] Furthermore, according to the outer wall panel of Device 3, since a non-combustible seal is provided at the joints of the heat insulating material on the side of the exterior material, the possibility of heat entering through the joints from the side of the exterior material can be reduced.

[0020] Furthermore, according to the outer wall panel of Invention 4, since the surface material is provided on the indoor side of the heat insulating material, the possibility of breakage, damage, etc. occurring and the possibility of heat, moisture, etc. entering can be reduced.

[0021] Furthermore, according to the outer wall panel of Invention 5, both abrasion resistance and elasticity can be achieved.

[0022] On the other hand, according to the construction method of the outer wall of Invention 6, since the heat insulating material has elasticity, it can be pressed and constructed during interference, and there is little need to perform caulking work. Therefore, compared with the conventional method, the work of outer wall construction can be reduced.

[0023] Furthermore, according to the construction method of the outer wall of Invention 7, by installing the elastic heat insulating material together with the exterior material on the column material, there is little need to separately perform fireproofing work on the column material.

Mode for Carrying Out the Invention

[0025] 〔First Embodiment〕 Hereinafter, the first embodiment of the present invention will be described. FIGS. 1 to 3 are diagrams showing this embodiment.

[0026] First, the configuration of this embodiment will be described. FIG. 1 is a perspective view of the outer wall panel 100. FIG. 2 is a vertical sectional view of the outer wall panel 100 along the line A-A' in FIG. 1. FIG. (b) in the same figure is an enlarged view of the dotted line part in FIG. (a).

[0027] Figure 3 is a horizontal cross-sectional view of the outer wall panel 100 along the line B-B' in Figure 1. Figure (b) in the same figure is an enlarged view of the dotted line part in Figure (a).

[0028] The outer wall panel 100 is a panel for attaching to a structural body to form an outer wall. For example, it is used as a curtain wall.

[0029] As shown in FIGS. 1 to 3, the outer wall panel 100 is configured to have a laminated panel material formed by laminating an exterior material 1, an outer heat insulating material 2, an inner heat insulating material 3, and a surface material 4 in that order. 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. As the steel material, for example, those with a thickness of 1.5 [mm] or more can be adopted.

[0031] The outer heat insulating material 2 is formed by connecting a plurality of rectangular plate-shaped elastic materials 2a in the plane direction. As the elastic material 2a, for example, those obtained by applying a colored non-woven fabric to the surface of a fire-resistant material such as rock wool can be adopted.

[0032] The inner heat insulating material 3 is formed by connecting a plurality of rectangular plate-shaped elastic materials 3a in the plane direction. As the elastic material 3a, for example, the same material as the elastic material 2a may be adopted, or a fire-resistant material different from the elastic material 2a can also be adopted.

[0033] The outer heat insulating material 2 and the inner heat insulating material 3 are laminated with the joints (hereinafter referred to as "joints of the outer heat insulating material 2") 2b that are the connecting parts of the elastic material 2a in the plane direction and the joints (hereinafter referred to as "joints of the inner heat insulating material 3") 3b that are the connecting parts of the elastic material 3a in the plane direction shifted. The vertical joints 2b of the outer heat insulating material 2 and the vertical joints 3b of the inner heat insulating material 3 are provided with an interval of, for example, 100 [mm] or more. The horizontal joints 2b of the outer heat insulating material 2 and the horizontal joints 3b of the inner heat insulating material 3 are provided with an interval of, for example, 100 [mm] or more.

[0034] The external heat insulation material 2 is fixed to the exterior material 1 by fasteners 2c. The fasteners 2c are composed of stud pins, washers, etc., and penetrate and fasten the external heat insulation material 2 and the exterior material 1 in the thickness direction. The vertical interval of the fasteners 2c is provided to be, for example, 600 [mm] or less. The horizontal interval of the fasteners 2c is provided to be, for example, 600 [mm] or less.

[0035] The internal heat insulation material 3 is fixed to the exterior material 1 by fasteners 3c. The fasteners 3c are composed of stud pins, washers, etc., and penetrate and fasten the internal heat insulation material 3, the external heat insulation material 2, and the exterior material 1 in the thickness direction. The vertical interval of the fasteners 3c is provided to be, for example, 450 [mm] or less. The horizontal interval of the fasteners 3c is provided to be, for example, 450 [mm] or less.

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

[0037] The surface material 4 is composed of, for example, a laminate of an aluminum foil, a plastic sheet, and a non-woven fabric. If each material of the aluminum foil, the plastic sheet, and the non-woven fabric is made thicker, the abrasion resistance is improved, but it becomes hard and the elasticity decreases. Therefore, in order to achieve both abrasion resistance and elasticity, it is preferable to adopt an aluminum foil with a thickness of 7 to 50 [μm], a plastic sheet with a thickness of 12 to 50 [μm]. More preferably, an aluminum foil with a thickness of 7 [μm], a plastic sheet with a thickness of 12 [μm], and a non-woven fabric with a weight of 15 [g / m 2 are adopted. A moisture-proof material can be further adopted for the surface material 4, which can prevent internal moisture from escaping and improve the fire resistance.

[0038] Next, the construction method of this embodiment will be described. Construct a bed or other structural framework. Then, attach a plurality of exterior wall panels 100 to the structural framework to construct the exterior wall. At this time, since the heat insulating materials 2 and 3 on the indoor surface have elasticity, they can be pressed against the structural framework during installation. And because the joints 2b and 3b are displaced, heat, moisture, etc. that penetrate through the joint 2b of the exterior heat insulating material 2 are blocked by the interior heat insulating material 3, and heat, moisture, etc. that penetrate through the joint 3b of the interior heat insulating material 3 are blocked by the exterior heat insulating material 2. Also, since a seal 2d is provided on the exterior heat insulating material 2, heat that penetrates through the joint 2b of the exterior heat insulating material 2 is blocked by the seal 2d.

[0039] Next, the effects of the present embodiment will be described. In the present embodiment, the exterior wall panel 100 is formed by laminating an exterior finishing material 1 on the outdoor surface and heat insulating materials 2 and 3 on the indoor surface. The exterior finishing material 1 is made of steel, and the heat insulating materials 2 and 3 are made of elastic materials.

[0040] Thereby, since the heat insulating materials 2 and 3 on the indoor surface have elasticity, they can be pressed against the structural framework during installation, and there is little need to perform gap-filling work. Therefore, compared with the prior art, the work of exterior wall construction can be reduced.

[0041] Also, since the exterior finishing material 1 is made of steel, the heat insulating materials 2 and 3 can be firmly attached. Even in case of a fire, the heat insulating materials 2 and 3 are less likely to fall off and are firmly fixed, so they are also resistant to vibration.

[0042] Furthermore, in the present embodiment, the exterior heat insulating material 2 and the interior heat insulating material 3 are laminated with the joints 2b of the exterior heat insulating material 2 and the joints 3b of the interior heat insulating material 3 being displaced.

[0043] Thereby, the possibility of heat, moisture, etc. penetrating through the joints 2b and 3b can be reduced.

[0044] Furthermore, in the present embodiment, a non-combustible seal 2d is provided on the exterior heat insulating material 2 so as to cover the joint 2b.

[0045] This can reduce the possibility of heat intrusion from the side of the exterior material 1 through the joint 2b.

[0046] Furthermore, in the present embodiment, a surface material 4 is provided on the indoor side of the internal heat insulating material 3. As a result, when the outer wall panel 100 interferes with other members, there is a possibility of breakage or damage when the outer wall panel 100 vibrates. In such a case, the surface material 4 can reduce the possibility of breakage, damage, and intrusion of heat, moisture, etc.

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

[0048] This can achieve both friction resistance and elasticity. Furthermore, in the present embodiment, the steel material of the exterior material 1 has a thickness of 1.5 [mm] or more.

[0049] This can more firmly attach the heat insulating materials 2 and 3. In the present embodiment, the external heat insulating material 2 corresponds to the first heat insulating material of Invention 2 or 3, and the internal heat insulating material 3 corresponds to the second heat insulating material of Invention 2 or 3.

[0050] 〔Second Embodiment〕 Next, a second embodiment of the present invention will be described. Hereinafter, only the parts different from the above-described first embodiment will be described, and the description of the overlapping parts will be omitted.

[0051] First, the construction method of the present embodiment will be described. In the first step, a floor or other structural framework is constructed.

[0052] Next, in the second step, the exterior material 1 is installed with a certain gap provided with respect to the floor material. Next, in the third step, a laminated heat insulating material formed by laminating the external heat insulating material 2, the internal heat insulating material 3, and the surface material 4 is installed along the exterior material 1 so that the gap between the exterior material 1 and the floor material is filled. When installing the exterior material 1 between the column members, in the third step, the laminated heat insulating material is installed along the exterior material 1 so as to cover one or both of the column members and fill the gap between the exterior material 1 and the floor material. In the laminated heat insulating material, the joints 2b of the external heat insulating material 2 and the joints 3b of the internal heat insulating material 3 are displaced, and the fact that the seal 2d is provided on the external heat insulating material 2 are the same as those in the first embodiment.

[0053] And in the fourth step, the laminated heat insulating material is fixed to the exterior material 1 by the fastener 3c. Next, the effects of the present embodiment will be described.

[0054] According to the construction method of the present embodiment, since the heat insulating materials 2 and 3 have elasticity, they can be pressed and constructed during interference, and there is little need to perform gap filling work. Therefore, compared with the prior art, the work of exterior wall construction can be reduced.

[0055] When installing the exterior material 1 between the column members, since fire resistance may also be required for the column members, conventionally, it was necessary to separately perform fireproof work on the column members. In contrast, according to the construction method of the present embodiment, by installing the elastic heat insulating materials 2 and 3 together with the exterior material 1 on the column members, there is little need to separately perform fireproof work on the column members.

[0056] 〔Modification Example〕 In the above first and second embodiments and their modification examples, the seal 2d is provided at the horizontal joint 2b of the external heat insulating material 2, but not limited thereto, the seal 2d can be provided at the vertical joint 2b of the external heat insulating material 2, the horizontal joint 3b of the internal heat insulating material 3, or the vertical joint 3b of the internal heat insulating material 3.

[0057] Also, in the above first and second embodiments and their modification examples, a two-layer structure is adopted as the heat insulating material, but not limited thereto, a single-layer or three-layer or more structure can be adopted.

[0058] In addition, in the above-described first and second embodiments and their modifications, the external heat insulating material 2 is fixed to the exterior material 1 by the fastener 2c. However, the present invention is not limited to this, and without using the fastener 2c, it can be fixed to the exterior material 1 together with the internal heat insulating material 3 by the fastener 3c. Similarly, when adopting a structure of three or more layers, two or more layers can be fixed to the exterior material 1 by a common fastener.

[0059] In addition, in the above-described second embodiment and its modification, in the third and fourth steps, a laminated heat insulating material formed by laminating the external heat insulating material 2, the internal heat insulating material 3, and the surface material 4 is installed, and the laminated heat insulating material is fixed to the exterior material 1 by the fastener 3c. However, the present invention is not limited to this, and the external heat insulating material 2 is installed along the exterior material 1, the external heat insulating material 2 is fixed to the exterior material 1 by the fastener 2c, and a laminated heat insulating material formed by laminating the internal heat insulating material 3 and the surface material 4 is installed along the external heat insulating material 2 so that the gap between the external heat insulating material 2 and the floor material is filled, and the laminated heat insulating material can be fixed to the exterior material 1 by the fastener 3c. Further, a method can be adopted in which the external heat insulating material 2 is installed along the exterior material 1, the external heat insulating material 2 is fixed to the exterior material 1 by the fastener 2c, the internal heat insulating material 3 is installed along the external heat insulating material 2 so that the gap between the external heat insulating material 2 and the floor material is filled, the internal heat insulating material 3 is fixed to the exterior material 1 by the fastener 3c, and the surface material 4 is installed on the internal heat insulating material 3.

[0060] In addition, the above-described first and second embodiments and their modifications can be applied to each other.

[0061] In addition, the present invention is applicable not only to the above-described first and second embodiments and their modifications but also to other cases without departing from the gist of the present invention.
