Abstract

PURPOSE:To improve durability by forming at least one of the surface plates of a door of a metal plate, in which enamel is baked on the surface. CONSTITUTION:A surface plate 1 consisting of an enameled metal plate is joined integrally with at least one of the surface and rear of a tabular structure 3 composed of a metallic frame 3a, a reinforcing article 3b such as a honeycomb, etc., and an outer frame 2 is mounted around the surface plate 1. Glass plates 5 having heat-insulating properties used as a skylight, etc., are fitted to the surface plate 1 as required, and patterns, etc., are carried out. Accordingly, the surface plate can be employed under a fine state over a long term of years because it is difficult to be flawed while mounting execution and opening and closing operation are enabled easily because of comparatively light weight, load applied to a hinge, etc., can be reduced, and fire resistance and appearance can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door for a building used as a doorway of a house or a partition of a house.

[0002]

2. Description of the Related Art Heretofore, as building doors of this type, there have been wooden doors, metal doors, and those having a decorative plate such as vinyl chloride attached to the surface.

[0003]

Among the conventional building doors described above, first of all, the wooden door has no fire resistance and has a problem in terms of safety, and it easily decays when exposed to direct sunlight or wind and rain, and is durable. It had a problem that the number of years was short.

Further, the metal door has a problem that it is rusted and has a large weight although it is excellent in fire resistance, and since its surface finish is painted, it cannot be used as a front door of a house, for example. However, there was a problem that a suitable quality feeling could not be obtained and the application was limited to fire doors.

A door having a decorative plate adhered to the surface thereof has a problem that it is inferior in fire resistance and durability although a high quality feeling is obtained, and that the surface is easily scratched by the contact of a key or the like.

[0006] As described above, none of the conventional building doors satisfy the functions of fire resistance and durability and have sufficient texture.

The present invention aims to improve this point.

[0008]

According to the present invention, at least one of the face plates constituting the door is formed of a enamel metal plate obtained by firing enamel on the surface, thereby solving the above problems.

[0009]

[Function] The enamel metal plate used as the surface plate of the door is not easily scratched and has excellent fire resistance and durability, but its surface is beautiful and various patterns and colors can be applied. It is possible to meet various demands from the house side such as design and quality. Further, the weight of the door can be made relatively light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a partially cutaway front view showing an embodiment of the present invention, and FIGS. As shown in the figure, the door for a building of the present invention comprises a metal frame 3a arranged at a predetermined interval and a reinforcing member 3b such as a paper honeycomb or an aluminum honeycomb arranged between the frames 3a and 3a. The front and back surfaces of the plate-shaped structure 3 that is
1 is integrally joined, and an outer frame 2 having a U-shaped cross section is attached to the periphery thereof.

Here, in the building door of the present invention, at least one of the surface plates 1 and 1 (preferably the side facing the outside) is made of a enamel metal plate. This enamel metal plate is coated with a glaze on the surface of a base metal thin plate, dried and then heated at a high temperature (about 800 to 85
It is formed by firing at 0 ° C.
If a desired pattern or color is applied to the surface of the base metal sheet in advance by means of transfer or the like, a beautiful enamel metal sheet having the surface covered with glass can be obtained.

Then, a through hole 1a is provided at a predetermined position of the front and back surface plates 1, 1 formed of the enamel metal plate or the like, and a glass plate 5 is provided in the through hole 1a via a frame body 4. It is fitted.

The through hole 1a can be used as a lighting window or a peep window, and can be used to change the design of the door. The shape and the position of the opening are not limited to those shown in the illustrated embodiment. However, it is optional, and is not necessarily provided when it is used for a fire door or the like.

The glass plate 5 fitted into the through hole 1a via the frame 4 may be transparent or translucent, but is preferably heat resistant glass.

In FIGS. 1 and 3, reference numeral 6 indicates a handle for opening and closing, which is attached at a predetermined position on the front and back of the door.

The building door of the present invention thus constructed is
As in the conventional case, the door is pivotally attached to one side such as an entrance (not shown) so as to be openable and closable and used, but as described above, in the building door of the present invention, the surface of the door is fireproof. Since it is covered with a enamel metal plate that has excellent heat resistance and heat resistance, it is highly safe and can be relieved in the unlikely event of a fire, and can be used not only as the front door of a house, but also as a fire door or boiler room. It can also be used as a door for dangerous goods storage.

Since the surface of this enamel metal plate is covered with enamel glass, it has corrosion resistance and excellent antifouling properties, and is exposed to harsh conditions such as wind and rain and direct sunlight. The door attached to can be kept in a beautiful state for many years, and there is no risk of its function being damaged by corrosion. Furthermore, since this enamel metal plate can be provided with desired patterns and colors, it is possible to form doors with various designs and tastes, and to provide a sense of quality that can meet the various demands of the residence. It can provide a high building door.

Further, since the building door of the present invention uses the enamel metal plate only for the surface plate, the weight of the entire door can be formed to be comparatively light despite its high strength.

In this embodiment, the structure of the door to which the surface plate is attached is made up of a metal frame and a reinforcing material such as a paper honeycomb or an aluminum honeycomb. Any material can be used as long as it can prevent bending and maintain its flatness. For example, as a frame, a synthetic resin material, as a reinforcement, gypsum board, asbestos cement calcium silicate board, fiber-containing calcium silicate board, various cements. The use of boards, plywood, fibreboard, etc. is conceivable. If the surface plate has sufficient strength,
The above structure is not always necessary.

[0020]

As described above, since the building door of the present invention has at least one surface covered with a enamel metal plate having excellent fire resistance and corrosion resistance, it is excellent in safety and hard to be damaged. It is easy to clean even when it is used in places exposed to harsh conditions such as doors and kitchen doors, and it can be used in a beautiful state for many years. Also, despite the high surface strength, the door can be made relatively lightweight, so that the installation work is easy and the operation during use is light, and the door is rotatably held. It doesn't force hinges.

Further, since it is possible to apply a desired pattern or color to the enamel metal plate, it is possible to give the building door a sense of quality not seen in the past, in combination with the unique texture of the enamel. Therefore, it is possible to meet various demands sought from diversified dwellers, and it is possible to provide doors for buildings with a sense of quality suitable for dwellings.

Further, it has been possible to improve the appearance of fireproof and fireproof doors without impairing their functions, which has been hardly considered in the past, and to promote positive utilization in this direction. Exerts the excellent effect of.
