BACKGROUND OF THE INVENTION
The present invention relates to a wall panel to be constructed on a wall portion of a house by a nailing or screwing method and an external insulation method using the wall panel.
[0002]
[Prior art]
Recently, the construction of houses by an external insulation method in which a heat insulating material is arranged outside the wall structure is increasing. Compared to the internal insulation method in which the wall structure is filled with a heat insulating material such as glass wool, this external insulation method constructs communication lines, electrical wiring, outlet boxes, air conditioning pipes, etc. inside the wall structure. Work is easy, and the inside of the wall structure can be used as a storage space such as a bookcase or a display shelf, or it can be taken in a part of the indoor space, and further, since the heat insulating material is outside the wall structure, Condensation is unlikely to occur inside the wall structure, and it has numerous advantages that mold and mites that feed on mold are suppressed.
In the conventional outer insulation method, a plurality of wall panels made of plywood having a thickness of about several millimeters to several tens of millimeters are arranged side by side so as to be joined in the left-right direction, and are screwed (nailed) to wall pillars and studs, respectively. Then, after applying an airtight tape along the seam of the wall panel, and then applying an insulating board made of rigid urethane foam having a thickness of about 40 to 50 mm to the entire outer surface of each wall panel with an adhesive, In general, a pier is arranged along the surface of the heat insulation board at a position facing a wall column or a stud, and an exterior material as an outer wall is nailed or screwed to the wall column from above the pier.
[0004]
[Problems to be solved by the invention]
However, as described above, after the wall panel is screwed to the wall column or the stud, at the construction site, an airtight tape is applied along the seam of the wall panel, or the heat insulation board is adhered to the surface of the wall panel with an adhesive. The external thermal insulation method to be attached has the disadvantages that the construction work of the house is remarkably longer and the construction cost is increased, because it takes more time for construction than the internal thermal insulation method.
[0005] Although a wall panel in which a heat insulation board is previously bonded to the entire surface of a panel body made of plywood or the like is commercially available, this type of wall panel has a heat insulation board affixed to the surface of the panel body with an adhesive. It is unnecessary to attach the panel body, but the end of the heat insulation board is retracted inward from the end of the panel body in order to screw the panel body to the wall pillar, so the gap where the insulation board is missing between adjacent wall panels In order to close the gap, it is necessary to embed a heat-insulated board cut into a narrow width in the gap, so that it takes time and time for construction and the construction cost increases. .
[0006] In the inner heat insulation method, waterproof paper is applied to the surface of the wall panel to give the wall structure a waterproof performance. In the case of the external insulation method, the waterproof performance is applied to the surface of the wall panel. In order to affix a heat insulation board made of a rigid urethane foam having no, it is common not to install waterproof paper. However, in Japan, where the amount of rainfall is large, even if a heat-insulating board having waterproof properties is exposed to moisture over a long period of time, its heat-insulating performance may deteriorate due to changes over time.
Accordingly, the present invention provides a wall panel in which a heat insulation board is bonded to one side of the panel body in advance, thereby greatly reducing the labor and cost of construction of the external insulation method, and at the same time, the panel of the wall panel. The main technical problem is to make it possible to directly nail or screw the main body to the wall column and to prevent deterioration of the heat insulating performance due to moisture of the heat insulating board bonded to the panel main body.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 is a wall panel in which a heat insulating board is bonded to one side of a panel main body nailed or screwed to a wall column, and the surface of the heat insulating board is waterproof. An end of the heat insulation board that covers a portion where the sheet body is attached and the panel body is nailed or screwed to the wall column is a width necessary for the nail or screwing operation while leaving the waterproof sheet portion cut off. It is characterized by being cut by the length and the cut end portion being non-adhered to the surface of the panel body.
In the wall panel of the present invention, since the heat insulating board is bonded to one side of the panel body, it is possible to save the labor of bonding the heat insulating board to the wall panel at the construction site. Moreover, since the waterproof sheet is attached to the surface of the heat insulation board, it is possible to prevent the performance of the heat insulation board from being deteriorated, and at the same time, it is possible to save the trouble of constructing the waterproof paper on the surface of the wall panel.
In addition, the heat insulation board bonded to the panel main body has a cut end portion that covers a portion where the panel main body is nailed or screwed to the wall column and is not adhered to the surface of the panel main body. At the same time, the waterproof sheet attached to the surface of the heat insulation board is connected to other parts of the heat insulation board like a hinge joint, and is provided so as to be able to move forward and backward with respect to the surface of the panel body. The panel body can be screwed directly to the wall column by separating the panel from the surface of the panel body.
After the panel body is screwed to the wall column, the cut end of the heat insulation board separated from the surface of the panel main body is pressed against the surface of the panel main body, and the piercing the cut end is pressed against the wall. If the pillar is nailed or screwed, the cut end portion of the heat insulation board is held and fixed in close contact with the surface of the panel body.
Next, the invention according to claim 4 is an external heat insulation method using the wall panel of the invention according to claim 1, and as described above, the cut end portion of the heat insulation board is separated from the surface of the panel body. After the panel body is nailed or screwed to the wall column after being separated, the cutting end is pressed against the surface of the panel body, and the timber that holds down the cutting end is nailed or screwed to the wall column. An exterior material serving as an outer wall is attached from above, and a ventilation layer is formed between the heat insulating board and the outer wall.
