Description

[Detailed description of the invention] This invention relates to a door made of beams, V, and L.

Conventional commercially available doors are broadly divided into solid doors, which are made of sawn wood panels, and panel-type doors, which are called flush doors.

In the first place, doors are used as openings in walls that partition rooms, so of course they can withstand severe opening and closing conditions. Doors are often exposed to different conditions, and the front and back sides of a single door are subject to different conditions, which requires resistance to warping and distortion, and the door also has sound insulation properties.

Fire resistance is also extremely important, and flush doors in particular have the disadvantage of lacking in performance in this respect.

Because solid wood doors are made of sawn wood, they are prone to warping and deformation. To solve this problem, special care must be taken to dry the door. For long doors, it may be necessary to allow a drying period of six months or a year, which reduces the cost. It has become expensive.

Therefore, this invention solves each of the above-mentioned drawbacks,
The objective is to provide LJ and L doors that are not only sound insulating and fire resistant, but also have less warping and deformation, are beautiful, and are inexpensive.

An embodiment of the present invention will be described below with reference to the drawings.
A veneer laminated material (L, V, I, Between the frames of the door material (2), that is, on the mirror surface, L4. A mirror plate material (3) composed of L is provided,
A decorative veneer (5) is pasted on the front and back screens of the door, and the mirror panel is carved deeper than the thickness of the decorative veneer.

L, V, and L are veneers laminated and bonded with the fiber directions substantially parallel, and dry material can be obtained in a short time. Furthermore, even if the wood has defects such as 9-knot cracks, those defects can be removed or dispersed.

In addition, since the product is a sufficiently dried material, there is little warping or deformation even after installation, and it can be an extremely effective base material for door materials. And, like sawn wood, the wood is filled to the inside, so it has a high surface specific gravity, has better sound insulation than flush doors, does not catch fire during PT, is fire resistant, and is made of solid wood. It has the characteristics of both a door and a 7-lattice door at the same time.

Even such excellent LJs and Ls have some defects dispersed inside the base material, so when engraving is applied later, such as on a door, the defects may become exposed.

Therefore, using a single piece of glue, V, L base material as it is for a carved door will greatly reduce the commercial value, so a combination of the frame material (1) and mirror plate material (3) of the present invention is required.

In other words, it may have some defects in the cross section, or it may be made of a single board with no defects by using V and L as the frame material, or it may be possible to use V and L as the frame board A, (. Since it is obtained from veneer, it is easy to harden the defect-free parts, and long pieces of material, which are difficult to obtain, can be used for frame materials.
Materials can be used effectively.

In addition, if the veneer used for the mirror panel IJ (3) and the decorative veneer (5) that is later attached to the entire surface of the door material are made of the same 41V type material, when carved, it will be possible to use one thick sawn wood. It looks like it has been used, and the appearance is beautiful, and it has a very inexpensive turnip look, VJ.
You will get a door.

Also, as a matter of course, there is a wooden edge veneer (4 pieces) on the side of the door material.
) may be attached.

By using a single color veneer or a different wood veneer for part or all of the decorative veneer (5) and mirror board material (3), a unique design that cannot be obtained with a single veneer can be achieved. This invention also has a great feature from this point of view.

Furthermore, if at least one of the V, L 41ii material (1) or the LVL end panel material (3) is used as a cross layer, the front and back outermost veneers (b) of the V, L doors will warp as a whole. It is useful to further reduce the deviation and prevent cracking of the decorative veneer after installation.

As mentioned above, the glue, V, and L doors of this invention are warped.

It has little distortion, has sound insulation properties, fire resistance, has a beautiful and unique design, and is inexpensive.

It provides V and L doors.

Example 1 11 sheets (3.1 m1rF + thick Japanese pine veneer) were laminated and bonded with their fiber directions substantially parallel to each other to form a V and L base material with a thickness of 32 mm.

At this time, the front and back outermost layer veneers (b) are cross-layered so that the fiber directions of the veneers are perpendicular to those of the other veneers. This was cut to a predetermined size to create a stile material (1), and the stile was assembled as shown in FIG. This method of assembling the frame may be either tenon or dowel assembly.

On the other hand, 17 sheets of 2 m/ln thick Chinese veneer (c) were laminated and glued with their fiber directions approximately parallel to each other to form a 32 mm thick glue, V.
Create the L mirror plate material (3) and cut it to a size that fits the inside of the frame assembly, that is, the mirror surface.At the same time as the frame assembly is completed, incorporate the mirror plate material and form the V-L door material (2). did.

Attach 2ψJ'/- Chinese veneer to the wood end veneer (4
), sanded the front and back sides to make them smooth, and then attached two 2 m/ln thick China decorative veneers (5) to the front and back surfaces to form a single sheet of 36 IV/In thickness. A door equivalent to a sawn board can be obtained.

Furthermore, the decorative veneer was cut with a router at the position corresponding to the mirror plate surface to give a deeper engraving than the decorative veneer, creating the V, I, and door shapes as shown in Part 4. Once painted, it became even more beautiful, with V and L doors.

Example 2゜Example 1. In the same process as above, the veneer for the mirror plate was immersed in a vacuum to uniformly color it in a light brown color.
By laminating them alternately with uncolored veneer or using V and L mirror panels, you can obtain a beautiful design with a striped pattern after carving, which cannot be achieved with sawn timber or flush door materials, or create a V or L door. Ta.
