Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides l! ! I! This involves forming approximately V7 grooves for dividing and joining wood pieces to cement boards.

In recent years, cement compositions have been mixed with shredded wood and water and molded into a predetermined shape. ? The hard plates used in this book are often used as wall materials for structures such as houses.
There is.

When forming and covering a part of the corner of a structure using such wall materials, tJ and vJ of two eels are shown in Fig. 1. υ (cross-sectional structure in which the ends of the wooden harement boards 1.1 are joined at right angles i!c), and the joint part C of the sandy wood cement board 1 and the end of one board is exposed. However, , the structure of this hard wood chip cement board 1 (in the areas near the front and back surfaces, the grain size of the wood chips is fine and the blending ratio of cement 1 is high; on the other hand, in the center, which occupies the majority, the grain size of the wood chips is coarse). The blending ratio of wood J1 is high (14 pieces are formed, and the waterproofing of the end 2 is insufficient.Moreover, the exposure of wood D2 is beautiful fill, and 1: is also unfavorable, resulting in a step at the joint. There is a drawback.

Therefore, as shown in Figure 2, 9J, a hard wood piece is attached to the board 1.
A roughly V-shaped groove is carved in the groove, so that the joint part is at an obtuse angle.
Form an angle lX1l kA i b, and ll on both sides! L.I.
Is Kagi cement board 1a and 1G abbreviated as V? A method was proposed in which groove surface 3-(') was used to form part of the corner of the outer wall of the house.

Part of the corner of the exterior wall of a house with this structure is w! as shown in Figure 3. Kagi Kata Romen 1 - 2 parallel V lines on board 1
) Form 1 to 4. (Cut and form two parallel approximately V shapes on the cement board 1 with a cutter not shown. Next, apply adhesive to the inner surface 3 of this approximately V shape) 1. Last. Then, lift both sides 1a and 1C of the hard wood cement 1 to the board 1 in the direction of the arrow (heat and harden the adhesive while keeping the shape of a part of the corner as shown in Fig. 2).

In the above-mentioned work of forming a substantially V-shaped shape on a hard wood cement board, it is difficult to accurately control the cutting depth of the cutter, and if the cutter cuts shallowly, the hard wood pieces Remen 1 to Board 1 If cracks occur and are deep, IiJ! The cement I-boards 1a, 11I, 1C of the wood pieces are scattered, and the joining becomes difficult. On the other hand, for decorative plywood, etc., a decorative plastic sheet 5 is bonded to the surface of the plywood as shown in Figure 4, and the plastic sheet is left on the plywood.
C13V-shaped grooves are being formed. However, the cold contact of the vibrating blade of the cutter with the Ab plastic sheet caused the plastic sheet to partially break or cause whitening when bent, resulting in an unsightly appearance.

The present invention solves the above-mentioned problems, and the blade is easy to adjust (and has good workability). The purpose is to provide the 'i method.

That is, the present invention provides C in a method of forming an abbreviated letter 1j4 for dividing and joining hard wood pieces 1 to 4k.
1. After pasting the adhesive 1j1 backing sheet 1~ on the surface of the hard wood board, cut and form a roughly V-shaped vortex that reaches the sheet from the adhesive backing 4J of the hard wood cement 1~board. It is characterized by this.

Hereinafter, one embodiment of the correction of the present invention will be shown, and the same amount of C.
explain.

FIG. 5 shows an example of the method of the present invention, and shows approximately V? Fig. 1 is a side view of a 4'l pear M forming a vortex. After that, hard wood piece rethane 1 - bamboo backing sheet 6 that is sticky from the back side of board 1
A cutter or the like (not shown) is used to form two flat grooves 4 that reach the groove 4.

This adhesive backing sheet 6 is preferably a thick woven fabric impregnated with a rubber adhesive. Alternatively, a plastic film coated with an adhesive may be used.

When forming the approximately V-shaped plate 4, the blade of the 7J ivy completely cuts the board 1 into the hard wood piece 1, and then cuts the adhesive backing sheet 6 into the adhesive backing sheet 6. The thickness of the sheet 6 is preferably a sufficient thickness (X).

Hard wood cement I forming a roughly V-shaped shape as shown in Figure 5
・The board 1 is covered with an adhesive backing sheet 6 as shown in FIG.
Apply adhesive to the inner surface 3 of the approximately V-shaped groove while the
It is heated and hardened into the shape of a part of the C corner.

Reference numeral 7 in the figure indicates an adhesive sweep portion provided on one or both of the substantially V-shaped groove surfaces 3.

If the cleaning area 7 is set up in this way and adhesive processing is performed with ( ),
The adhesive applied to the approximately V-shaped groove 3 is held by the sweep portion 7,
When both edges of the approximately V-shaped groove surface 3 are glued together and heated for adhesive assimilation treatment, the adhesive will overflow onto the adhesive surface to prevent adhesion failure due to lack of adhesive. J [Rir. In this way, there is no freezing of excess adhesive that protrudes from areas other than the adhesive surface, resulting in a beautiful finish.

After that, the adhesive backing 11+j and sheets 1-6 are peeled off from the free trade wood board 1.In addition, peel off the adhesive backing 1j and sheet 1-6 and take it with a separate clamp etc. it
Do some work (I can't do it).

Because of this, it's sticky! 1" and 1-6 are IIJ peeled bamboo σ
) It's amazing how good the adhesive layer is.
Ig shield 1'1-end of work C viscous activity 941' and sea 1-6
Attach the Cl+) it l, and the adhesive will dig into this surface.
A part of the corner has been completed for the best sushi.
Then, "-ki + fJ! Trade tree 1'+-1? The surface of board 1 is painted, etc., and snow falls outside.

According to the method υ of the present invention explained above, after pasting the adhesive backing sheet 1~ on the back side of the hard wood cement board, approximately V
As a result of forming δ, it is not possible to completely cut the board, and even if the cutter blade reaches the adhesive backing sheet, the sticky backing sheet is still intact. It absorbs depending on the thickness, and the adhesive backing sheet 1 ~ sticks to the surface of the board to the hard wood J1 cement 1, so lol! Even when the purchased wood pieces Pmen 1~ are bent and joined together, the adhesive backing 1~ does not turn white and scatter, and the lining effect is high. Therefore, it is possible to assemble hard wood element boards with a good appearance.

In addition, a sweeping part is provided in a full V shape (if there is one, it will be possible to easily apply enough adhesive for bonding, and the cleaning part will hold the contact material, allowing the contact There is no possibility of defective adhesion due to insufficient adhesion.Furthermore, since adhesion is performed at both edges of the substantially V-shaped groove, it has sufficient strength.
