It concerns the method.

In conventional wooden bathtubs, if the wood becomes too dry, the Jl value of the wood will be 1. Or,
1, it was difficult to mass produce it, and the 41 had the drawbacks of tIz and rod.

However, even now that stainless steel and Plus Book l6 tank 7'I have appeared, nine 1fl bottles of the amulet are still available.
#1' The goodness of the wood skin is widely praised (Iru, 1
The present invention was developed in view of the above circumstances, and while taking advantage of the good qualities of wood, the defects peculiar to wood 14-1) are removed, and cracks, twists, etc. death,
It is an object of the present invention to provide the present YLT assembly bathtub and its manufacturing method, which is resistant to water leakage, easy to manufacture, and mass-produced.

Hereinafter, the present invention will be explained with reference to Embodiment 1c shown in the drawings.

FIG. 1 is a plan view of a 9ft bathtub according to an embodiment of the present invention, and FIG. 2 is a vertical sectional view thereof.

The bathtub (1) is made of wood 5+, and the joint edge (3
) are connected to a plurality of unit members (2) made of wood-based materials such as cypress or shingles with the same cross-sectional shape, and the joint edges (3) are joined together, and the four strips (4a) and the convex strips (4b ) are butted together at an angle and formed into a hollow columnar shape with a substantially circular cross section using adhesives 1 to 1. ).

Next, we will explain the manufacturing method of the above-mentioned wooden bathtub. First, prepare a plurality of materials such as wood with a uniform width, length, and thickness of 19.17F', and use a cutter or saw to cut the edges of the materials. As shown in Fig. 3, a plurality of unit members (2) having the same cross-sectional shape with the joint end R (3) shaped like a finger are made by alternately opening the four strips (4a) and the convex strips (cross) in parallel. Form.

Note that the convex ridges on the joint edge (3) of this unit material (2)
N (A) that connects the top of or the bottom of Shijo (4a)
The angle (θ) formed by (A) is determined depending on the number of unit members (2) forming the l-tree columnar material and the shape, particularly the cross-sectional shape, of the columnar material. For example, 24 111th place 44 (2)
When molding a columnar material with an approximately circular cross section of −r + 4, t is set to 1, approximately 15°.

Next, as shown in Figure 4, J
'+l'i- arranged adjacently and consecutively, 17 consecutive pieces,
Medium 1. ! Attach multiple strips of +i) (7) such as paper tape or cloth Deso to the - side surface of (2) in the width direction to fix each middle +4 (2) arrangement. In addition to pasting this flexible sheet 1 (7) t, t, 1- as shown, continuous units 11 (7) One stick in the direction, 1”N l-
.

But that's fine.

Then, the appropriate position li'l k? on the inner surface of the unit material (2)?
',,1tjtC-shaped concave IPg (8) is formed in the width direction -fz).

After that, take the flexible sheet (7) as a guide and -tf
Bend the material (2) in order to make a finger-shaped 1″EE.
At the mating edge (3), insert the first and second position materials (2) at an angle so that the four strips (4a) and the convex strips (4b) are engaged, and glue one circle to the other at an angle.1. Then, form the side body (5).

Then, a fitting groove θ with a cross section of 1 character 1 Hi is provided on the upper edge of the side body (5).
b), and fit the stainless steel round Jjl material (I barrel into the bottom fitting groove (ll+), and the fitting groove 06).
Pour a synthetic resin with a desired color inside the side body (5
) to make the side body (5) more robust. Note that the fitting groove 06) may be formed in advance on the upper part (2) before forming the side body part (5).

On the other hand, as shown in FIG. 5, the bottom plate (6) K that is fitted into the inner bottom of the side shell (5) also has a groove (9) with a U-shaped cross section similar to that of the side shell (5) on its periphery. It has been cut and polished so that the bottom fits inside the nine side body (5), and the concave groove (8) of the side body (5) and the concave groove (9) of the bottom plate (6) match. K is formed so as to form a cavity (11).

Next, on the side surface of the side body (5), JItR is applied to the through hole (I) so that it communicates with the cavity (11).Then, from the through hole (11), a two-component solution type urethane resin, etc. Inject and fill the synthetic resin.Then, the synthetic resin will harden and
The side body (5) and the bottom plate (6) are fixed together.

After the unit material (2) is glued together, the unit material (2) is glued together.
2) If the flexible sheet (7) is removed from the outer surface, the wooden bathtub (1) is completed. In this example, the unit material (2
) In order to make the joint part of the joint edge (3) beautiful, the outer surface of the side body (5) is polished and polished.
At that time, (1 (iiJ jF, % sheet (7) is also 1 (1 "7), -J'Z" (, 711th position material (2)
is not limited to the upper side, and the shape of A2 may also be a substantially trapezoid on the tfJi plane, etc.
For example, various types of plywood, laminated wood, etc. can be used, and as shown in Figure 6, the surface of the base plate (1?) such as a wood board can be used. TEJ'TI is laminated with H03 surface such as beautiful and high quality natural wood veneer.

The surface material (1 piece was completed 17 times;+?j
It may be made to appear on the outer surface of the tank.

In addition, instead of the previous example, the injection force of the flexible resin etc. is, for example, as shown in FIG. Interval gap 04) is Il
'd +t'J.

A step i (iN:G) is placed on the circumference of the bottom plate (6) so that the
l, the gap 04) and the gap On jj! 8 to the gap (+41, L: IJ gap part (1 1817.4CJl) to the synthetic resin such as phrethane resin in 1 ira. ) It is convenient to be able to visually check the amount of goods injected, etc.

As is clear from the above, K 111th ((), one edge of the convex width is formed into a finger shape, for example, and a plurality of the unit materials and the grooves are held at an angle so that the four strips and the convex strips engage with each other at the joint edge. Since it is formed into a columnar shape with butt adhesive 17, the peculiar defects of wood are removed, and warpage and warping are avoided.
F3+J, F3+J, etc., are used to make various types of bathtubs by using single-phase wood such as shingle or cypress as a unit material, which is less likely to crack or twist, has a large bonding surface between the base material and the oshi, has strength and durability, and has a good fragrance.
Can be built.

As for the manufacturing method, a synthetic resin such as phrethane resin is injected into the gap formed by the grooves formed in each of the side shell and the bottom plate, and after filling 1 to hardening, the bottom plate is fixed to the side shell. Therefore, it is extremely easy to manufacture, and by arranging a predetermined number of unit materials adjacent to each other in a horizontal row and pasting a flexible sheet on the surface of the consecutive unit materials, each unit material can be manufactured. Fix the arrangement and use the flexible sheet as a guide to attach the crowning material and Hexagram 1.
- Since the parts are bonded and bonded, there is no fear that the unit materials will come apart during the manufacturing process, making the manufacturing process easier. It is extremely convenient because it can be simplified and streamlined, and commercially available paper tape, cloth tape, etc. can be used for the flexible sheet.
