Abstract

(57) [Abstract] [Purpose] To provide laminated veneer lumber by laminating and adhering veneer laminate. [Structure] A laminated veneer laminated material in which a prescribed number of laminated veneer laminated with finger joints or scarf joints at predetermined lengths are laminated and adhered by shifting a predetermined number of the joint joints in the longitudinal direction.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement in a laminated veneer laminated sheet obtained by laminating and bonding a plurality of laminated veneer laminated sheets.

[0002]

[Prior art]

 Laminated lumber, which is a sawn plate, is adhesively bonded, and structural veneer laminated material, in which veneers are laminated and bonded in the same fiber direction, has been widely used in various fields. It has come to be used as a relatively large-scale structural member such as a beam and a pillar of a wooden building. However, because of its large cross-section and length, it is difficult to manufacture even if these laminated wood or structural veneer laminates are used.

[0003]

[Problems to be solved by the device]

 Generally, when manufacturing a long veneer laminate, the rotary veneer is carved in a direction perpendicular to the fiber direction, so it is possible to make a continuous strip in this direction, but in the fiber direction the The length of the lace is determined by the width of the lace and the length of the log, and the length of the veneer is limited. In order to secure sufficient strength, the joint positions of vertically adjacent veneers must be separated by about 30 times the thickness of the veneers, and the joint positions cannot be arranged near the same cross section. However, there is a drawback that the yield is reduced. In addition, if a hot press is used to hot-press a multi-layered single plate at once, it takes a long time. The present invention proposes a new laminated veneer lumber, which is simple and easy for mass production.

[0004]

[Means for Solving the Problems]

 The present invention is characterized by the fact that a predetermined number of laminated veneer materials, which are finger-jointed or scarf-joined at predetermined lengths, are bonded in a predetermined number of layers by shifting the joint joint parts in the longitudinal direction. Laminated wood, or one of the above laminated veneer lumber laminated to the outer layer of the laminated veneer lumber, and the laminated veneer lumber laminated with laminated veneer or decorative paper. It aims to provide laminated veneer lumber that is bonded together.

[0005]

[Action]

 As described above, the present invention, as described above, laminates a single plate laminated material in which finger joints or scarf joints are joined at predetermined lengths by laminating and adhering the joint joints with their phases shifted in the front-rear direction. Since long veneer laminated materials are bonded together, and these are integrally bonded together with a decorative veneer, by combining these veneer laminated materials appropriately, thin plates, thick plates, columns, etc. This will make it easier and more efficient to produce laminated laminated wood. As a result, laminated veneer lumber will be placed as a regular material such as housing material. Such laminated veneer lumber will be improved in quality without warping or cracking due to drying. In addition, by wrapping and bonding with a veneer for makeup, the quality is improved in terms of decoration and appearance as interior materials such as construction materials, surface materials, and pillar materials.

【Example】

 Examples will be described with reference to the drawings. FIG. 1 is a laminated veneer lumber laminated with a predetermined number of laminated veneer lumbers that are finger-joined at predetermined lengths with the finger joint joints being shifted in phase in the front-back direction. A plate laminated material, and the veneer used for the veneer laminated material is a veneer mainly obtained by peeling with a rotary race, and has a thickness of 1.5 mm to 10 mm. The length of the veneer in the fiber direction is specified by the length of the raw wood stripped by the rotary lace, but it need not be longer than the press plate of the press. Do not use the veneer of this veneer formed by meshing with a scarf or zigzag and connecting them vertically. However, a veneer laterally bonded in the fiber direction of the veneer is a method of obtaining sufficient strength, and it is a preferable method to use a veneer bonded laterally. A plurality of the above-mentioned single plates laminated and bonded in the fiber direction are the single plate laminated materials 1 and 1'having predetermined dimensions. Reference numeral 2 is a finger joint. This joint is formed by forming a well-known finger joint 2 on the end of the above-mentioned laminated single plate material, and shifting the phase of the joint 2 in the front-rear direction as shown in the figure, and laminating and adhering a predetermined number of sheets. The laminated laminated wood 3 is constructed. Fig. 2 shows a single plate laminated material that is finger-joined to each other at a predetermined length, and the fingers are joined to each other by shifting the finger joint connection part in the front-rear direction with a predetermined number of layers and adhering one sheet to the outer layer part. It is a laminated veneer lumber laminated with laminated veneer lumber. FIG. 3 shows a laminated veneer laminated material in which the finger joint joints are phase-shifted in the front-rear direction for each predetermined length, a predetermined number of them are laminated and adhered, and they are integrally wrapped with a decorative veneer 4.

[Effect of device]

 Conventional laminated wood is manufactured by laminating and adhering lumber or small square timbers, but the single laminated wood laminated wood of the present invention has higher productivity than conventional laminated wood. The product yield is improved. Veneer laminated wood laminated wood has the defects such as knots and cracks dispersed more than conventional laminated wood, and it is possible to easily obtain veneer laminated wood laminated wood with desired strength with simple equipment at low cost. . The laminated veneer lumber can be used as a stable housing material with less warping and cracking due to drying, etc., and it is possible to improve the quality. The laminated veneer lumber has the properties of homogeneity, safety, durability, stability and economy, which are characteristics of laminated veneer lumber.
