Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a door with a wooden frame that has excellent fire prevention performance.

0002

[Conventional technology]

Traditionally installed in openings in hotels, condominiums, apartments, etc. Doors are designed with fire-retardant performance in order to block fire and smoke in the event of a fire, and prevent the spread of fire. The one with the following is used. As a door with such fire-retardant performance, Generally, metal doors are used.

0003

[Problem that the idea aims to solve]

However, with metal doors, the reverberation of knocking and opening/closing sounds is large, and they also interfere with surrounding sounds. It has poor soundproofing performance, such as poor absorption and resonance. Also, look and feel It has a cold feeling peculiar to metal, and it is difficult to feel comfortable especially when touching it. It is difficult to form three-dimensional designs on surfaces, and many of them lack a sense of luxury due to their flat surfaces. Problems include the fact that it is a heavy item and does not have good workability during construction. have. Furthermore, regarding fireproofing performance, although it is a non-combustible material, it does not catch fire in the event of a fire. The heat of the flames may deform the metal, allowing smoke to enter and making it difficult to open and close the door. However, there are problems that may impede firefighting and rescue operations. It was not effective.

0004 Doors made of wood-based materials have excellent soundproofing performance, are pleasant to the touch, and have a surface finish. Door materials that are easy to construct, give a sense of luxury, and are easy to install. However, due to poor fire prevention performance, practical use as a fire door is extremely difficult. It was difficult.

[0005]

[Means to solve the problem]

Therefore, the present invention solves the drawbacks of the above-mentioned conventional technology and has developed a wooden door with excellent fire prevention performance. The purpose is to provide a

[0006] In order to achieve this purpose, the present invention, which was created after intensive efforts, has been developed to reduce the size of the door frame. At least the door stop member, and preferably also the head plate constructed within the door frame, should be provided with a barrier. This is a door with a wooden frame that is characterized by being fire-treated.

[0007] The door frame is made of solid wood, laminated wood fiberboard, particle board, O. S. B. ,L. V. L. ,L. V. B. It is made of wood-based materials such as door The structure and shape of the frame are arbitrary, for example, a pair of vertical frame members connected at their upper ends. These include those that consist of horizontal frame members tied together, and those that are arch-shaped. Multiple door frame configurations In the case of components, each component is assembled and joined using a conventional method, but This is likely to be a weak point in fire protection performance, so when gluing the joint, It is preferable to use a flame retardant or non-combustible adhesive.

[0008] The door body, which is hinged to the inside edge of the door frame so that it can be opened and closed, is also connected to the door frame. Made from similar wood-based materials. As for the structure of the door body, for example, you can optionally use a frame. A mirror plate can be fitted into the assembled frame frame to give it a luxurious feel. child In this case, when joining each stile member that makes up the stile frame, the above-mentioned door frame As with the joints between each component, use flame-retardant or non-combustible adhesives to ensure fire-retardant performance. It is preferable to protect weak points.

[0009] The surfaces of these door frames and door bodies include natural veneer, artificial veneer, decorative paper, and decorative stickers. Applying makeup by pasting decorative materials such as paint, or by any means such as painting or printing. I can do it. When applying these optional cosmetic measures, it is necessary to improve fire prevention performance. First, a known flame retardant or flame retardant is applied to the decorative material, or mixed into the adhesive. Alternatively, consideration should be given to mixing it into the paint.

0010 As is well known, the inner surface of the door frame has a door stop against which the inner edge of the door body comes into contact. It is formed so as to protrude inward. Even if this door stop is integrated with the door frame, , or may be configured as a separate body. The doorstop, which is constructed as a separate body, Fit the protrusion formed on the back side into the recess on the inner side of the door frame, or use a connecting member such as a dowel. It is fixed to the inner side of the door frame using adhesives, nails, etc.

[0011] Please note that the door frame should have a width that matches the wall thickness to be constructed. However, it is also possible to use one whose width can be adjusted to accommodate different wall thickness dimensions. For example, a pair of arm-shaped casings are installed on both sides of a relatively narrow door frame. The casing is removably inserted, and the insertion length of this casing can be adjusted to match the wall thickness during construction. The type that is configured to be adjusted and used, and the door frame itself in its width direction (indoor It was divided into two parts (side and indoor side) and constructed into a parent frame and a child frame, and one of them was first fixed to a pillar etc. The so-called adjustment frame tab is configured to later fix the other parts at arbitrary distances according to the wall thickness dimension. Ipu is known. In the case of the latter configuration, the doorstop is located between the parent frame and the child frame. integrally formed on one surface or fixed by any means, but not on the other surface. The required length in the width direction is extended to cover the Care has been taken to ensure that the gap space is not exposed when

0012 In the wooden framed door of the present invention, the door stop is treated with fire prevention treatment. Prevention Fire treatment is performed, for example, by the following method.

[0013] stomach. Apply known fire prevention chemicals such as flame retardants and noncombustible agents directly to the door stop to impregnate it. Ru. The applied fire retardant agent should be applied near the surface of doorstops that come into direct contact with flames in the event of a fire. Due to the dense impregnation in the surrounding area, efficient fire protection is achieved.

[0014] B. Inside the cell pores of the wood material that constitutes the door stop, which is separate from the door frame, and/or or filling, adhering, or fixing a nonflammable inorganic compound along the inner wall surface of the cell pore; The nonflammable inorganic compound is also attached or fixed to the front and back surfaces. This method is applied in this application. A person first proposed in Japanese Patent Application No. 1-157185 (Japanese Patent Application No. 3-27199) etc. It has been confirmed that the treatment has an excellent treatment effect.

[0015] C. Form a metal coating layer on the surface of the doorstop by thermal spraying or attach metal foil. Ru. Door stops are generally inconspicuous parts, so even if you apply this treatment, It does not lose the overall wooden feel of a door with a frame, and is a key point in the design. It can be emphasized as an accent.

[0016] Any of the above may be used for fire prevention treatment for the doorstop, and these treatments may also be used. The above processes may be combined as appropriate. Of course, other effective means can also be used. It is possible.

[0017] In this invention, applying fire prevention treatment to the door stop of the door frame means that the door stop with a wooden frame is This is essential in order to provide extremely excellent fire protection performance. That is, do We focused on the fact that the gap between the door frame and the door frame served as a path for flames to pass through during a fire. This is because the doorstop installed in the gap space is treated with fireproofing. , can exert a lasting effect of blocking flames, and also prevent smoke from entering the room. Intrusion can be effectively prevented.

[0018] As mentioned above, it is essential for this invention to apply fire prevention treatment to the door stop of the door frame. However, if necessary, other parts of the door frame or the entire door frame may be covered in the same manner as above. Fireproofing treatment may be applied. If the entire door frame is treated with fire protection, it will This effectively prevents the door frame from being burnt out, which protects the edge of the door. This works to delay the combustion of the stile frame, which is the main structure of the door, and increases the durability of the door as a whole. Contributes to improving flammability.

[0019] When using the door body of this invention with a head plate fitted inside the frame, the head plate However, it is preferable to apply fire prevention treatment. This strengthens the decorative effect on mirror panels. The structure of the door body is uneven because the surface is uneven and has a thin wall part to adjust the temperature. During construction, the area becomes extremely disadvantageous in terms of fire resistance, and it is necessary to improve the fire resistance of the area. Because there is. The fire prevention treatment for the head panel shall be done by the Fire Prevention Bureau for the above-mentioned door stop. It may be the same as the above-mentioned process, and may be used to apply optional decorative means to the mirror plate as described above. Fire prevention treatment may also be applied.

[0020] By improving the fire resistance of the end plate inside the frame in this way, the fire resistance inside the frame is improved. This prevents the head plate from coming off or cracking due to combustion, and prevents the head plate from coming off or cracking, which would normally occur when igniting a fire. This prevents warping and cracking of the stile frame, and by extension the door itself, in the event of a fire. Even in the event of a fire, it is possible to maintain a stable shielding function as a door. This greatly contributes to safety.

[0021] Furthermore, even under normal conditions, the end plate treated with fireproofing as described above has a This is caused by mixing or filling materials such as fire retardants and non-flammable inorganic compounds into As a result of structural changes or surface coating with metal foil etc., surrounding frames may Dimensional changes are smaller compared to frames. Therefore, by using the end plate with excellent dimensional stability, this The stile frame surrounding the frame is maintained, preventing dimensional changes and cracking of the stile board itself. This effectively avoids problems with opening and closing the door, especially in high humidity conditions. be done.
