[Industrial applications]

 The present invention relates to a fire door.

[0002]

[Prior art]

 Since the promulgation of the Ministry of Construction Notification No. 1125 in 1990, development and approval of wooden fire doors have been underway. Among them, the Otsukin wood type fire door is a composite of a gypsum-based or calcium silicate-based non-combustible plate and wood, a particle board having a thickness of 30 to 40 mm as a core material, and a flame-retardant treatment. There are some that use fire-retardant treated wood.

[0003]

[Problems to be solved by the device]

 However, when an inorganic non-combustible plate is combined with wood, the inorganic non-combustible plate easily absorbs moisture and is liable to peel off at the adhesive layer, warp or crack of the wood, and even when processed, the non-combustible plate It is difficult to collect the powder of the above, it easily scatters, the working environment becomes poor, and the durability of the blade becomes poor. Further, the one using the thick particle board as the core material is heavy and difficult to handle. In addition, the wood made from flame-retarded wood required a processing step, which required a long processing time.

[0004]

[Means for Solving the Problems]

 The present invention has been made in view of the above circumstances, and has a concave fitting portion along the longitudinal direction, a frame material in which foam material is embedded on opposite side surfaces, and a fitting convex portion for forming a wooden material. It is characterized in that a panel in which a decorative material is adhesively processed is integrated on the front and back of the base material, and a frame is extended at the boundary portion between the frame and the panel. Hereinafter, the present invention will be described in detail with reference to the drawings.

FIG. 2 is a partial cross-sectional view of the fire door of the present invention, in which the frame (1) and the panel (2) are integrated. The frame material (1) is a laminated core material (3) made of medium / high-density wood with a specific gravity of 0.5 to 0.8, and is used as a frame core material (3). 4), and the foam material (5) is embedded in the opposite side surfaces. As the foam material (5), water glass type, graphite type and the like can be applied. In the event of a fire, the foam material (5) foams and seals the fire door and the opening, thereby exerting an action of blocking internal or external flames.

In the panel (2), the particle board (6) is used as a core material for the panel, and the front and back of the particle board (6) are provided with a decorative material so as to have a fitting convex portion (7). (8) is adhesively processed. As the core material for the panel, other wood base materials such as medium density fiberboard, plywood, and laminated wood can be applied.

A frame (10) is extended by a pin (9) at the boundary between the frame (1) and the panel (2), and the frame (10) is embedded to a depth reaching the particle board (6). ing. As a result, the frame (1), the panel (2), and the frame (10) are firmly joined by the pin (9), and therefore the fire test of Ministry of Construction Notification No. 1125 is passed. As the frame (10) and the frame material (1), those printed on plastic, those coated on solid wood, etc. can be applied.

As for the decorative material (8), a coating veneer sheet, a vinyl chloride sheet, a coating printing sheet, etc. are adhered to a wood base material such as plywood, fiberboard, chipboard, etc. to give a design. Applied cosmetic materials, melamine resin decorative boards, diallyl phthalate resin decorative boards, polyester modified decorative boards and the like can be applied.

The above-mentioned cosmetic material (8) adhered to the front and back of the panel (2) is adhered to the periphery of the frame material (1), and in consideration of the finished appearance and workability, A decorative material (8) capable of V-cut attachment such as a coated veneer sheet laminated sheet is more preferable.

Various adhesives can be used for adhering the particle board (6) or the frame core material (3) and the decorative material (8), but phenol having good fire resistance and flame retardancy is used. Resin adhesives and resorcinol resin adhesives are preferred.

Further, it is possible to attach a graphite-based or water glass-based heating foam material to the fitting portion (4).

[0012]

[Effect of device]

 The fire door (12) has the performance to pass Class B fire doors according to the test method of the Ministry of Construction Notification No. 1125 of 1990 in conformity with JIS A1304 (fire resistance test method for building structures). By sealing the door and the opening by foaming the material, it has the effect of blocking internal or external flames and preventing fire spread. Further, it is possible to solve problems such as heavy weight, poor heat insulating property, poor working environment, etc. in a fireproof door having a conventional non-combustible plate such as a plaster-based material interposed therein.
