Description

[Detailed description of the invention] The present invention relates to a door member and a manufacturing method thereof.

Conventionally, door opening frames, frames, and other door components have been made from sawn single materials, but the processing yield rate of wood is as low as approximately 30%, creating problems in terms of resource conservation. Because it expands and contracts depending on external conditions, especially humidity, it can crack, warp, twist, and other shape changes over time, making it difficult to open and close, and making it difficult for each door to close. was there. In particular, wood called ate wood undergoes severe shape changes and has a usage rate of μTME, so a solution has been strongly sought.

The present invention relates to a door member that solves the above problems and a manufacturing method thereof.

The present invention will be described in detail with reference to the drawings of one embodiment.7'
While rotating the log, a rotary race is used to apply a cutting force in the direction of the log's attachment to the log in a peel-like manner.
1) was prepared, and then dried in a dryer to an equilibrium water level of about 4 degrees, and the dried veneer (2) was coated with a melamine resin-based dusting agent (3) (4), and then transferred to a lamination unit ( W) is pressurized and heated in a hot press to form it, and then cut to obtain the vertical door frame material (v) 0 Similarly, the drying ratio board (2), short - 〇 dry veneer) and steel #(force) with urethane resin adhesive (3) t''m cloth and coated veneer (
41-A laminated part (5) in which the fiber directions are parallel to each other and an array part (6) in which four coated veneers and coated steel (7') are arranged alternately are layered in p#A order. The laminated unit (8) is formed using a hot press to create a vertical door frame material (9+). Regarding the process of manufacturing the drying rate board (1) and (2), the already known plywood manufacturing process can be adopted.
For the materials that are mainly used in the northeast, raw wood is immersed in warm water, then green veneer with a thickness of Fgrg is cut using a rotary race, and dried veneer is produced. Dry veneer (7
) In addition to the above-mentioned steel wire, the bar-shaped metal material placed on the jumper is made of iron, stainless steel, aluminum alloy, or other materials.

Shaped pipes, shaped materials, etc. are used. The thickness and thickness of the metal material are equivalent to the thickness with the drying rate of 81 (2'), and the number of Wr surface rams and number of rams used is such that it can suppress changes in shape such as warping and twisting of the molded member. It is sufficient if the selection is made so that the ratio is the same.

In addition, if post-processing (cutting, etc.) is performed after molding in order to attach metal fittings such as locks and scissors to predetermined positions of each member, the metal material is not placed in the predetermined position or is placed intermittently. It is sufficient if a method such as The veneer (
2) The adhesive for fully bonding (r) and the metal material or the veneer (2) is a thermosetting 1M resin such as epoxy, urethane, unsaturated polyester, water-based vinyl urethane, phenol, resorcinol, melamine, etc. The adhesive is compatible and preferably does not cause rust or corrosion on metal materials.

Furthermore, the mechanical Ili! of the adhesive layer in the adhesive! For the purpose of improving the degree of hardness, fiber materials such as multi-wire fibers and synthetic fibers are mixed in, and in order to foam and fill the voids that occur at the butt part between the veneer and the metal material, the curing reaction of the adhesive is heated and sluggish. A foaming agent component or a resin component that foams and increases in volume by heating during molding may be used.

When the manufacturing method of the door member according to the present invention is adopted, the wood utilization yield is about 30 - if a single material is used by the conventional lumbering method, but the wood utilization rate is about 30 -, whereas the wood utilization rate is about 30 -. In addition, it can be used by modifying the 7-hole part (by punching most of it and fitting a veneer of the same shape, etc.) or using G-IT veneer.
It can be improved to ~70%. In addition, since the veneers are laminated in parallel, even if the edges are cut into a comb shape, they will not become partially fluffed and the outside will not be visible. In addition, the core material of raw wood,
Since sapwood etc. can be selected and used, components can be homogenized.

At the same time, each member formed using this method, such as vertical frames, horizontal frames, and opening frame materials, is homogeneous and is made of a metal material whose elongation elasticity and compression elasticity are much larger than those of a single material, so they absorb moisture and absorb moisture.
Rurui is partly elongated due to drying, JvIJ partly elongated stress,
Even if compressive stress occurs, it is suppressed, making it difficult to cause shape changes such as warping and lines.

In addition, cracks that occur inside are blocked by the adhesive layer, as shown in Table 1j.
It has the advantage of not being as slow as i3V.
