Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exterior panel for forming an exterior part of a building such as a prefab house.

[0002]

2. Description of the Related Art In recent years, for example, in the construction of houses, a prefab construction method has been widely adopted in which a house is constructed by assembling wall panels, roof panels, floor panels, etc. manufactured in advance in a factory at a construction site. By the way, as a panel used in such a prefab method,
It is common that a wood surface material made of plywood or the like is attached to both or one of the frame bodies assembled in a rectangular frame shape by a core material. Further, in some of the panels, instead of the wood surface material, an inorganic surface material made of gypsum board, lightweight cellular concrete or the like is attached to a frame body to improve heat resistance and the like.

[0003]

However, in the above panel, when these are used for the exterior part, that is, the outer wall or the roof, there are the following inconveniences. In the panel formed by attaching a wooden surface material to the frame body, after assembling this in the field, as a finish, a waterproof layer made of a waterproof sheet or the like is attached to the surface to be an exterior part, and further on it. After installing the furring on, stick the siding. However, since such finishing is done on site, it will prolong the construction period, and further, if it rains after assembly and before finishing, the core material may get wet and the durability after construction may be impaired. ..

Further, even a panel formed by adhering the above inorganic surface material needs to be waterproofed, and if it rains on site, before the waterproofing, water permeates the inorganic surface material. There was a possibility that the core material could be painted. Also, if it is suitable for the inorganic surface material, it may be cracked by a strong impact, and especially if the inorganic surface material is cracked, the part that is cracked by some fibrous material such as wood becomes the surface material. There was a problem that it did not stay stuck and the cracked part fell off and holes were made in the panel.

The present invention has been made in view of the above circumstances. An object of the present invention is to prevent the core material from getting wet during on-site construction and to provide a panel when the inorganic surface material is subjected to a strong impact. It is to provide an exterior panel that does not have a hole in it.

[0006]

An exterior panel of the present invention comprises a frame body assembled in a rectangular frame shape by vertical and horizontal core materials, and a face plate attached to at least the exterior side of the frame body. And forms the exterior part of the building,
The face plate is formed in three layers from an inner surface material attached to the frame body, an outer surface material attached to the outer surface side of the inner surface material, and a non-woven fabric layer sandwiched between the inner surface material and the outer surface material. The inner surface material and the outer surface material are provided with concavities and convexities corresponding to each other on respective joint surfaces where the inner surface material and the outer surface material are joined to each other, and are bonded to each other with the nonwoven fabric layer sandwiched therebetween. At least the outer surface material of the inner surface material and the outer surface material is formed of an inorganic surface material, and the non-woven fabric layer has a three-layer structure in which a net is sandwiched between two waterproof non-woven fabrics. This is the means for solving the above problems.

[0007]

According to the above construction, the face plate has a three-layer structure in which the non-woven fabric layer is sandwiched between the inner face material and the outer face material and is bonded to each other, and the non-woven fabric layer is formed between two non-woven fabric layers. Since there are three layers sandwiching the net, the non-woven fabric layer absorbs the impact applied to the face plate and reinforces the face plate. Further, even when the face plate is cracked due to impact, the non-woven fabric layer that is difficult to cut by sandwiching the net, because the cracked face plate is adhered, the cracked portion does not fall from the panel, It is possible to prevent the panel from being punctured by an impact.

Further, when an exterior panel manufactured in advance in a factory is assembled at a construction site, even if it rains and the exterior side surface gets wet, moisture permeates the outer surface material and moves to the inner surface side of the outer surface material. The non-woven fabric layer composed of two waterproof non-woven fabrics prevents the migration of water to the inner surface material side.

Further, the width of the ridges 8a of the outer surface material 8 is formed to be slightly narrower than the interval between the ridges 7a of the inner surface material 7, and even if the nonwoven fabric layer 9 is sandwiched, the ridges 8a of the outer surface material 8 are sandwiched. …
There is a gap between the ridge and the ridge 7a of the inner surface material 7. Then, this gap communicates from the upper end to the lower end of the exterior panel 1.

Here, it is preferable to apply a known waterproofing agent or moisture-proofing agent to the outer surface of the outer surface material 8 in advance, in order to enhance the waterproof and moisture-proof performance of the obtained outer panel 1. .. Further, the ridges 7a of the inner surface material 7 and the outer surface material 8
, 8a, etc. are formed by forming irregularities corresponding to the protrusions and the like on the mold when forming the inner surface material 7 and the outer surface material 8.

As shown in FIG. 4, the non-woven fabric layer 9 has two layers.
It is composed of three layers with a net 9b sandwiched between sheets of non-woven fabric 9a. The non-woven fabric 9a is made of polyester,
Synthetic fibers such as polyethylene or a mixture of these synthetic fibers, which are made into a felt shape and melt-bonded to each other, and those formed into a woven shape, or the synthetic fibers are bonded using a resin serving as an adhesive or a binder, It is formed into a woven fabric. As such a non-woven fabric, for example, Tyvek (trade name, manufactured by DuPont Japan Limited), Espoir (trade name, manufactured by Mitsui Toatsu Kagaku Co., Ltd.) and the like are known. In this example, Tyvek is used. ing. The non-woven fabric 4 has a waterproof property and a moisture permeability, and can prevent water from entering from the outside and can diffuse vapor inside.

The net 9b is made of a chemical fiber such as polyester. The net 9b is made of several chemical fibers to form a thread and is woven in a lattice pattern. The two non-woven fabrics 9a and 9a are bonded to each other with the net 9b sandwiched therebetween.

For the attachment of the inner surface material 7 and the outer surface material 8 with the nonwoven fabric layer 9 sandwiched therebetween, a known impregnated adhesive which has been conventionally used for bonding inorganic surface materials is used.
Since the inner surface material 7 and the outer surface material 8 are bonded by the impregnating adhesive, the bonding strength between the inner surface material 7 and the outer surface material 8 via the nonwoven fabric layer 9 is not impaired. Further, the inner surface member 7 is also adhered to the frame body 2 by a conventionally known adhesive.

In manufacturing the exterior panel 1 having such a structure, first, the vertical core members 2a, 2a and the horizontal core members 2b, 2b are first manufactured.
The frame 2 is formed from the above, and the auxiliary core materials 2c ... Are arranged inside the frame 2. Next, the inside of the frame body 2 is filled with the heat insulating material 6, and the inner surface material 7 is attached to both surfaces of the frame body 2. Next, the non-woven fabric layer 9 is placed on the inner surface material 7, and the outer surface material 8 is attached to the inner surface material 7 so as to correspond to the protrusions 7a ... And the protrusions 7b. At this time, alignment can be easily performed by associating the protrusions 8a of the outer surface member 8 and the notches with the protrusions 7a of the inner member 7 and the protrusions 7b.

Next, in order to form the outer wall of the house by using the exterior panel 1, a plurality of exterior panels 1 ... Are connected so as to have a desired size. Here, as the joining between the exterior panels 1 and 1, known means such as nailing, bonding, joining with a joining metal object is adopted. Further, regarding the corners of the outer wall, as a treatment of the end surface of the exterior panel 1, a treatment with a dry sealant which is conventionally performed is adopted. The finishing process of the exterior surface is performed by applying a coating material containing an organic solvent such as mortar or acrylic.

In the exterior panel 1 as described above, the exterior surface material 8 serving as the exterior surface is made of an inorganic surface material that can be used as the exterior material. Can be completed, and the finishing of the exterior surface can be reduced compared to the conventional case.

The outer surface material 8 can be easily aligned with the inner surface material 7 by fitting the cutout portions.

Further, since the non-woven fabric 9a has waterproofness, when the exterior panel 1 manufactured in advance in the factory is assembled at the construction site, it rains and the surface on the exterior side gets wet and moisture Even if the water permeates the outer surface material 8 and migrates to the inner surface side of the outer surface material 8, the non-woven fabric layer 9 is waterproof so that the migration of water to the inner surface material 7 side can be prevented.

Further, even when the face plate 4 is subjected to an unexpected impact during transportation or assembly, the non-woven fabric composed of the two non-woven fabrics 9a, 9a and the net 9b is provided between the inner face material 7 and the outer face material 8. Since the layer 9 is provided, the non-woven fabric layer 9 absorbs a part of the impact, so that the impact on the exterior panel 1 can be reduced.

In addition, even after the exterior panel 1 is used to build a house and the exterior panel 1 is impacted and the outer surface material 8 and the inner surface material 7 made of inorganic surface materials are cracked,
Since the cracked portions of the outer surface material 8 and the inner surface material 7 are adhered to the non-woven fabric layer 9, the cracked portions do not drop and the exterior panel is not punctured.

Further, since there is a vertically communicating gap between the outer surface material 8 and the inner surface material 7, and the non-woven fabric 9a has a moisture permeability, the outer surface material made of a hygroscopic inorganic surface material. Since moisture in the outer surface material 8 and the inner surface material 7 passes through the nonwoven fabric layer 9 and is discharged to the outside through the gap, dew condensation does not occur inside the outer surface material 8 and the inner surface material 7 or inside the exterior panel 1. .

Although the exterior panel 1 of the present invention is applied to an outer wall panel in the above-mentioned embodiment, the exterior panel 1 may be applied to a roof panel, for example.
The face plate 4 may be attached only to one side of the exterior panel 1 shown in FIG. The inner surface material 7 does not need to be an inorganic surface material, and may be plywood or the like. At this time, the ridges 7a are formed by adhering a thin plate-like plywood or the like on the plywood.
