Abstract

PROBLEM TO BE SOLVED: To provide a building panel without deformation such as swelling, warping, or the like after manufacture, also excellent in mechanical strength. SOLUTION: A building panel A comprises a core material 3 consisting of synthetic resin foam body sandwiched between a surface material 1 and a rear surface material 2. In this case, at least on the rear surface of the surface material 1 or on the boundary surface between the surface material 1 and the core material 3, a strap like long permeable member 4 is fitted and arranged to be covered with a sheetlike material 5. Accordingly, the mechanical strength of the building panel A itself is enhanced, and the reaction gas or vapor inside the core material 3 is discharged to the outside from the end grain surface of the building panel A through the permeable member 4 itself, or through a void α formed by covering the permeable member 4 with the sheetlike material 5, so that a bad influence such as warping and swelling is not exerted on the building panel A after manufacture.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can be used as an inner wall material, an outer wall material, a roof material, a ceiling material, a floor material, a partition material, a fire door, or the like of a building or a building, and swells after manufacturing.
The present invention relates to a building panel which is free from deformation such as warpage and has excellent fire resistance, fire resistance and mechanical strength.

2. Description of the Related Art In general, a large number of architectural panels in which a core made of a synthetic resin foam is sandwiched between a thin plate-like front surface material and a back surface material have been invented, devised, and put on the market.

[0003]

However, in a building panel using a synthetic resin foam as a core material as described above, the self-adhesiveness of the synthetic resin foam is generally weak, and the surface material and the back surface material are hardly used. The adhesiveness to the core material was poor, and peeling was easy to occur. Generally, when various types of synthetic resin foams are used as the core material, the mechanical strength of the building panel itself is inferior, and due to the aging of the synthetic resin foam, irregularities may occur on the surface of the building panel or warp may occur. In some cases. In addition, when a core material is formed, a reaction gas is generated and remains in the core material. In particular, when the core material is a phenol foam, the condensed water at the time of reaction in the core material is several tens percent by weight. During the curing period of the product or after the construction panel is installed, moisture changes into steam due to changes in the outside temperature, etc., and there is no escape route. In some cases, such a problem may occur that gas remains or warps on the back surface of the surface material or the back surface of the backing material of the building panel, which adversely affects the building panel over time.

[0004]

SUMMARY OF THE INVENTION In order to eliminate such drawbacks, the present invention relates to a building panel in which a core material made of a synthetic resin foam is sandwiched between a front surface material and a back surface material. On the back surface (boundary surface between the surface material and the core material), a string-shaped long air-permeable member is attached so as to be covered with a sheet-like material, and is disposed, so that the mechanical strength of the building panel itself is improved. The air-permeable member itself and the void formed by covering the air-permeable member with a sheet-like material emits the reaction gas and water vapor in the core material to the outside from the opening edge of the building panel, and the building after manufacture. The present invention proposes an architectural panel that does not adversely affect the panel for use such as warpage and swelling.

A gap α is formed between the sheet member 5 and the air-permeable member 4 due to the thickness of the air-permeable member 4.

The void α functions as an air passage together with the air permeable member 4, and is formed by the influence of the residual acid component of the curing agent or the foaming agent used for the core 3 after the core 3 is manufactured. Gases such as surplus gas components (chlorine, carbon dioxide, methylene chloride, formaldehyde, water vapor, hydrogen) that have undergone a chemical reaction or condensed water during the reaction are released to the outside from the cross-section of the panel A for construction. Is what you can do.
