Description

[Detailed description of the invention] The present invention relates to door structures.

Traditional doors were mainly made of wood, but wood materials have anisotropy unique to wood (difference between core material and sapwood, difference between spring wood and summer wood, etc.), and also have moisture content. There were problems such as warping, twisting, and large expansion/contraction ratios due to local differences in the temperature, making it difficult to close the door, making it difficult to seal, and damaging the appearance. For fire prevention purposes, non-combustible materials were required for Kaai housing.

This book by Akira solves the above four points regarding a nine-door l1ffi in which a door member with a decorative finish applied to the surface of an inorganic base material is assembled.

The present invention will be explained in detail according to the drawings of the embodiments. Fig. 1 is a front view of the door in which the hv, vertical (1>), horizontal grip (2), and -board (3) members are assembled. Each member is made of a calcium silicate plate with a ratio of 0.6Of/lI (1'l surface with a basis weight of 120?/l, and a 1'l non-woven fabric with a weight of 0.00f/l on a non-woven fabric).
The veneers from 5 to 9 are glued together using cherry blossom glue, and the 9 decorative materials (8) are glued together.

The main raw materials for the silicic acid lucium board used as the base material are calcilum sources such as slaked lime or quicklime, and silicic acid sources such as silica sand or silica clay, and are mixed with water and reinforcing fibers such as asbestos fiber and glass fiber. Using raw materials, the mixture is molded or made into a predetermined thickness using a paper making machine (wet machine), and then steam cured (steam pressure 8 to 15 Iv1!).
, 5 to 20 hours) to promote the crystal growth of calcium silicate to obtain a molded plate, or to cure the raw material in a curing pot to produce a crystal growth body of calcium silicate, and then mold it while dehydrating it. Also, 5BR in the crystal growth body
Water dispersion resin materials such as SNBR, MBR1 latex, polyvinyl acetate, polyacrylic [13], emulsion blinds, polyvinyl alcohol, polyethyleneimine, polyethylene oxide, water f#ra polymers, etc. are mixed or kneaded and then dehydrated. There is a method of obtaining a molded plate by molding while Depending on the curing conditions, tobemolite crystals,
Although a xonotrite crystal is obtained, it has a higher degree of fire resistance,
The latter is preferable for gaining strength. The specific gravity of the molded board is determined by the combination sluice, molding pressure, or type of raw material, but the ratio J [affects the bending strength, compressive strength, and screw retention force of the laminated board, and is related to the total weight of the door. It is necessary to select within an appropriate range from silica clay, slaked lime (

As is well known, the cutting properties of chain acid templates are equivalent to those of wood.
! Processing such as #JvrnvJ system and Yaroke can be carried out with conventional wood processing and 10J pass, as well as frame joining (dowel joints, assembling, etc.) processing required for each member of door materials, II
I] There is no problem with compost processing, etc. As a base material, in addition to calcium silicate board, gypsum board, magnesium carbonate board, etc., which have the same machinability, can also be used.As for the decorative method for the cough base clothing, painting or pasting of decorative materials can be used, but For white doors, silicic acid calci, ram board, stone, etc. may be used. For decorative finishing of the surface of the base material, etc.: For base materials with ratio 1, the surface Since the powder on the layer or surface layer tends to fall off and the decorative layer easily peels off, it is necessary to perform a sheet treatment with good permeability in order to reinforce the 5A surface layer, or use an organic binder (as described above in water dispersion) at the time of formation. This problem can be solved by mixing a resin material ate). For the surface painting finish, each type of grafted G * 13m wood is used, and for the paper finish, vinyl chloride resin film, acrylic w fat film, Doug resin decorative board, Mefumin (11 fat decorative board, polyester josei makeup) Decorative materials such as resin-based decorative materials such as boards, veneer boards (natural or artificial), and decorative fabrics (paper) can be used.The decorative materials can be bonded using a flat plate press or vacuum if the decorative materials are easily bendable. The molding method can also be used, making it ideal for contacting uneven surfaces such as chamfered parts and mirror plates.

Door materials using inorganic base materials such as silicic acid lucium boards include vertical, horizontal, obi, tsuka, and wood. In order to solve the problem of dimensional changes, it may be used only for the problematic members and shared with wooden members.

The door formed according to the present invention uses an inorganic base material and is round and non-flammable, making it useful for disaster prevention.

Since the cutting ability is between wood, etc., the wood processing equipment can be used as is.
The assembly method can be used in the same way, either dry or dry, and has good processing workability.

Moreover, as shown in Table 1, there is no dimensional change or warping, so the sealing performance is poor and the outside 11! There is no harm to it.
