PROBLEM TO BE SOLVED: To provide a laminated floor material, and laminated internal, external wall members which are inexpensive, and in addition, are hard to generate a deviation due to warpage or shrinkage. SOLUTION: A wood face side or a wood rear side is arranged on the one surface side, and the direction of the grain is matched to obtain plate constituent members 1, 2 by bonding and adhering a plurality of plate materials 1a, 1b, 1c... or 2a, 2b, 2c... in a row by finger joints 1j, 2j, and two sheets of the plate constituent members 1, 2 are bonded and adhered using an adhesive in such a manner that the surfaces where the wood rear side is located may face to each other.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a floor material for a house,
Also, the present invention relates to a laminated material used as an inner or outer wall material, and particularly to a laminated material which is inexpensive and hardly generates warpage due to warpage or shrinkage.

[0002]

2. Description of the Related Art In general, floor materials are designed so that the smoothness and gloss of the surface are emphasized, and in order to facilitate planar processing of the surface, the front side of the wood (the outer peripheral side of the wood, the center of the wood). The opposite side is used as the front side, and this applies not only to ordinary plate materials, but also to plate materials made of laminated wood. For this reason, there has been a problem that both side edges in the width direction of the plate material are warped to the surface side due to repeated use of the temperature and the wet and dry due to repeated use, making it difficult to see. The present invention has been made in view of such circumstances, and an object of the present invention is to provide a glued laminated lumber capable of easily preventing warpage by bonding wooden backs.

[0003]

Means for Solving the Problems The laminated wood according to the present invention comprises:
A wooden surface or a wooden back is positioned on one side and a plurality of plate materials aligned in the direction of the grain are joined to each other in a row by a finger joint. The present invention is characterized in that the surfaces located are bonded to each other with an adhesive. According to the present invention, by bonding the backs of the trees together, the force of the warp in the width direction of the board is cancelled, the knitting hardly occurs, and the flatness can be maintained even after long-term use. Wood is obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below with reference to the drawings showing an embodiment in which the present invention is applied to a flooring material. FIG. 1 is a perspective view of an embodiment showing a case where the laminated wood according to the present invention is applied to a laminated flooring. In the drawings, reference numerals 1 and 2 denote plate components constituting the laminated flooring. The plate component 1 is composed of a plurality of plate members 1a and 1b having the same width and the same thickness (lengths are variously different).
Are joined and bonded in a line by finger joints 1j with the wooden surface facing the upper surface and the direction of the metal mesh in the same direction. Plates 2a, 2b having the same width and thickness (different lengths)
Are joined and adhered to each other in a line with a finger joint 2j in a state where the wooden surface is on the lower surface side and the direction of the heather is aligned. In addition, to align the direction of the heather eyes,
It means that the direction of the heatsink is not the direction of intersection, and the base and the end of the tree may be aligned in the same direction, or may not be aligned.

[0005] The two boards 1 and 2 have their backs joined to each other using an adhesive, and are formed as a single laminated floor. In the case of the glued floor material, a no-joint portion such as a cypress, a cedar or the like is used as the plate material 1a, 1b... As for ..., the articulated portions such as cypress and cedar are also used. Note that, as the adhesive, an adhesive having a small effect on the human body by the solvent is used.

Next, a method for manufacturing such a laminated floor material will be described. FIG. 2 is an explanatory view showing a main manufacturing process of the laminated floor material. (A) First, a plate material (core material) having the same thickness is connected using a finger joint. As shown in FIG.
.., 31a, 31b... Fingers are formed at the respective connection ends and are bonded and bonded using an adhesive to form two laminated materials 20 and 30. Each plate 21a, 21b
, 31a, 31b ... have the same thickness and the same width (the length may be different). In particular, the thickness is selected to be substantially the same as or larger than the thickness of the laminated floor material as a product.

FIG. 3 is an enlarged side view of the finger joint 22 of the plate shown in FIG.
Are formed in the connection end faces of the plate members 21a, 21b... So that the plate members 21a, 21b.
The top or bottom of the concave portion 22m or the convex portion 22n at a position approximately half the plate thickness of b ... (usually, the ratio of the divided plate thickness may be within the range of 5: 5 to 4: 6). Is formed to be located. Then, the sawing position is set to the concave portion 22m or the convex portion 22.
n to the top or valley bottom,
Alternatively, the plate members 21a, 21b, 31a, 31
Only one straight line appears at the connection portion between b, and the aesthetic appearance of the surface as the flooring material is not spoiled.

(B) As shown in FIG. 2, two sheets of glued wood prepared in (A) are prepared, and two sheets (or an integral multiple) are taken along line AA and line BB so that each has the same thickness. ), And two plate components 1 and 2 as shown in FIG.
Above integer number). In this case, it is not always necessary to divide the center of the thickness so as to have the same thickness. (C) Plane processing is performed on each of the split surfaces, and the surfaces where the wooden backs are located are bonded to each other using two adhesives for two plate components 1 and 2 having the same thickness. (D) One side in the width direction of the glued laminated wood in which the surfaces on which the wooden backs are located are bonded together as shown in FIG.
1y and 31y, and the other side are processed with ridges 21x and 31x. (E) The surface on the side that should become the floor surface remains unpainted,
Or apply paint. As a result, two laminated floor materials as shown in FIG. 1 are obtained.

[0009]

According to the first and second aspects of the present invention, since the backs of the trees are bonded together, the warpage and bending in the width direction of the board can be offset,
It has excellent effects such as warpage and shrinkage due to shrinkage, irrespective of changes in temperature and dryness, flatness can be maintained over time, and it can be manufactured at low cost.
