Description

The present invention mainly relates to a wooden safe having a strong wooden fire door used in a Japanese-style house such as a general wooden house, an apartment house, and an inn.

Conventionally, as a fire door used for, for example, a safe, a fire door that is made of metal is generally known.
However, although a fire door device using a metal fire door is strong, the weight of the door itself is very heavy, and the fire door itself warps due to high heat, and there is doubt about the fire performance of the metal fire door device. It was aimed.
Furthermore, there was a problem that the radiant heat was increased to 5 to 8 times higher than that of a general wooden door.

By the way, in recent years, in Japanese-style houses such as wooden general houses, apartment houses, and inns, there has been an increasing demand for installing wooden safes rather than installing metal safes because of the relationship with other wooden furniture. ing. In addition, there has been a growing demand for wooden safes with a strong wooden fire door.

There is no secular change even with use, so there is no sudden drop in fire performance, and the fire performance itself can be improved over conventional wooden fire doors and metal fire doors. High, that is, a fireproof time of 60 minutes or more is possible, and the weight is lightened. In addition, there is no sense of incongruity when installed in Japanese-style houses such as wooden ordinary houses, apartment houses, inns, etc. The wooden safe is also harmonized with the wooden furniture, so that it is possible to provide a wooden safe having a strong wooden fire door called a so-called 60-minute fire door.

  Hereinafter, the present invention will be described with reference to the drawings.

First, the wooden fire door 1 will be described.
Here, the wooden fire door 1 is formed having a core material 2 composed of a plurality of paulownia laminated plates.
The paulownia laminated material constituting the core material 2 according to the present invention is known as a laminated material having excellent workability since it is very light and has few cracks and deviations.
Also, when the surface is polished, it becomes glossy and beautifully finished. Furthermore, since it is a heat-insulating and non-flammable tree, it has recently been used in fireproof doors and other small items such as small items and furniture.

  A major material 3 is attached to the outer peripheral end surface of the core material 2. As the material of the major material 3, for example, a decorative glass fiber mixed magnesium silicate plate or the like is used. Further, a heat expansion material 15 is interposed between the outer peripheral end face of the core material 2 and the major material 3. As the heat-expandable material 15, an expanded sponge material or an expanded rubber material is used.

Further, non-combustible paper 8 made of a combustion delay member, a fireproof sheet 4 and the like are attached to both side surfaces of the core material 2. Here, the non-combustible paper 8 has a thickness of about 1 mm and is made of, for example, magnesium silicate, pulp, glass fiber, or the like.
The fireproof sheet 4 has a thickness of about 0.6 mm, and the material is, for example, silica cloth.

  Thus, the incombustible paper 8 and the fireproof sheet 4 are attached to both sides of the core material 2 in the order of, for example, the incombustible paper 8 and then the fireproof sheet 4, and the decorative plywood 5 is bonded to the outside thereof. For example, it sticks through epoxy and the wooden fire door 1 is formed.

  The production of the wooden fire door 1 according to the present invention will be described.

First, the first laminated material 6 of paulownia is produced by laminating and bonding in parallel to the fiber direction. Then, the generated first paulownia timber 6 is arranged with its direction determined so that the fiber direction is vertical. Here, it is the thickness of the first laminated material 6 of paulownia, but is formed thicker than the thickness of the second laminated material 7 of paulownia described later.
For example, if the thickness of paulownia second laminated material 7 to be described later is about 9 mm, the thickness of paulownia first laminated material 6 is about 13 mm.

  Next, the single plate is laminated in parallel with the fiber direction and bonded to produce a second paulownia laminated material 7 having a thickness smaller than that of the first paulownia laminated material 6.

Then, the second laminated material 7 is disposed so that the fiber direction is a horizontal direction, and the second laminated material 7 of paulownia determined in the direction is bonded to the back surface of the first laminated material 6.
The point is that the thickness of the first laminated material 6 is made thicker than the thickness of the second laminated material 7.

Next, the above-mentioned noncombustible paper 8 and the fireproof sheet 4 are adhered to the surface of the first laminated material 6 to form a core material unit for the fire door 1.
Further, a pair of the generated core member units are arranged so that the second laminated members 7 face each other, and then the second laminated members 7 in the core member unit are, for example, silicic acid having a thickness of about 0.25 mm. The core material 2 for a fire door is formed by adhering via a second non-combustible paper 9 made of magnesium, pulp, glass fiber, or the like.

  Thus, the core material 2 for the fire door 1 according to the present invention has a paulownia first laminated material 6 and a paulownia second laminated material 7 overlapped to produce a core material unit. The core unit is overlapped through the second non-combustible paper 9 to form four sheets, and the thick first laminated material 6 side is on the surface side, and the thin second laminated material 7 side is on the inside. The core material 2 is arranged and further considered for improving fire prevention performance.

  Moreover, as described above, the first timber laminated material 6 with the fiber direction set to the vertical direction and the second paulownia laminated material 7 with the fiber direction set to the horizontal direction are crossed in a substantially right angle manner. Since they are bonded together and are further bonded in two sets, the fireproof performance is improved as the core material 2, and the strength as the fireproof door 1 is also greatly improved. .

Moreover, as described above, for example, the non-combustible paper 8 and then the fireproof sheet 4 are attached to both outer side surfaces of the core member 2 in this order, and the decorative plywood 5 is bonded to the outer side thereof with an adhesive, for example, epoxy. Pasted.
With the wooden fire door 1 constructed in this way, a fireproof time of 60 minutes or more can be obtained compared to the conventional one.

  Thus, a major material 3 made of a combustion delay member made of a decorative glass fiber mixed magnesium silicate plate is attached to the outer peripheral end face of the core material 2 in the fire door 1 to form the fire door 1.

  A wooden safe 10 according to the present invention is formed by attaching the fire door 1 to the front surface of a frame framed in a substantially case shape by both side members 11, a bottom member 12, a top member 13, and a back member 14. It is assumed that an electric auxiliary lock 16 is attached to the fire door 1.

The side members 11, the bottom material 12, the top material 13, and the back material 14 are formed by laminating a plurality of, for example, about three, 13 mm paulownia first laminated materials.
Further, incombustible paper 8 and fireproof sheet 4 are interposed therein, and not only the fire door 1 but also the frame itself constituting the safe is provided with fire prevention performance.

  Next, the usage state of the wooden safe having the strong wooden fire door according to the present invention will be described.

First, in the present invention, the above-described invention was proposed for the formation of the core material 2 of the wooden fire door 1 that is suitably used as a door having fire-proof performance of trapping fire and heat when a fire occurs. That is, a core unit was formed from the paulownia first laminated material 6 and the paulownia second laminated material 7 having different thicknesses. Then, a pair of core material units were further stacked and bonded to form a core material 2 of four original paulownia laminated materials. In addition, a plurality of non-combustible papers 8 and fireproof sheets 4 are interposed therein.
By constructing in this way and manufacturing with paulownia laminated wood with low thermal conductivity, the heat insulation and fireproof performance were further enhanced.

  That is, even if the surface side of a wooden safe having a strong wooden fire door according to the present invention is burned with a high heat of nearly 800 degrees, the temperature on the non-heated side, that is, the inside of the safe, is touchable. Conventional metal safes are deformed by high heat, and it is very dangerous when the metal itself becomes hot.

  Moreover, the wooden safe having a strong wooden fire door according to the present invention includes a core material 2 of the fire door 1 using a unique paulownia laminated material, a plurality of non-combustible papers 8 and 9 and a fireproof sheet 4 interposed therein. The fire protection performance is greatly improved by combining.

  For conventional wooden cores, wood boards such as MDF are often used, but the weight is as heavy as about 100 kg. In addition, a general metal fireproof steel door weighs about 70 kg, and it is somewhat difficult for the general public as well as young people and elderly people to use it.

  Thus, the wooden safe having the strong wooden fire door according to the present invention uses the laminated paulownia of four layers of paulownia with different thicknesses as the core material 2, and the above-mentioned noncombustible paper 8 for the thickness. , 9 and refractory sheet 4, etc., the weight is light, easy to carry in and install, lightly burdened on the building frame, and smooth to use.

Furthermore, the core material 2 made of paulownia laminated material absorbs relatively low sounds, and the fireproof sheet 4 reflects high sounds. Therefore, the sound insulation performance is also at a high level.
In addition, it has heat resistance and heat insulation properties that exceed those of steel fire doors, is difficult to burn, does not generate smoke, and does not warp due to heat. That is, there is no warp due to flame heat, and the smoke and flame are shut out.
In addition, durability is improved in combination with a high-rigidity composite structure using paulownia laminated wood that has a rigidity that is not easily distorted and hardly deteriorates.

Improves energy-saving effect and sound insulation of air conditioning, and is resistant to aging. Conversely, paulownia laminated lumber is not deformed by moisture absorption or temperature changes, and as the years pass, the material tightens and the strength increases.
In addition, the antibacterial effect of paulownia having a humidity control function does not rot, and it is durable and hygienic.
Furthermore, in consideration of the global environment, paulownia is used as a plantation material, giving consideration to precious forest resources and the global environment.
