Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a structural orthogonal laminate,

The present invention relates to a method for producing a structural orthogonal laminated sheet material suitable for strength grade, product specification and construction method so as to utilize domestic timber resources as effectively as possible and to be applied to domestic wooden construction, and a method for producing structural orthogonally- Lt; / RTI >

In order to prevent global warming, which is the biggest problem in this century, wood is recommended as a structural material for carbon storage. Korea has also designated residential buildings as hanok with national projects.

Also, the growth rate of middle and large sized wooden buildings such as hanok is rapidly growing to about 20% every year. Unlike other construction methods, the wooden structural members of Hanyok-in use large structural members such as pillars and beams, so it is difficult to supply domestic timber and relies on imported timber for 90% of the required amount.

On the other hand, structural orthogonal lamellar plates were developed under the name of Cross Laminated Timber (CLT) or Cross-Lam and X-Lam in the EU region such as Switzerland in the 1990s. Currently, they are used in Europe, USA, Japan, Australia, The use of wood as a rebuilding material is expanding.

Particularly, the large plate material has the greatest feature that can be used as a kind of this material as well as the role of walls, floors and roofs mainly of wall structure as well as soccer preparation materials such as pillars and beams It is a woody plate material that has the potential to become a new woody structural material in the future.

In order to secure the strength performance, the structural orthogonal lamellar members are arranged in parallel with each other. In order to secure the strength performance, a parallel laminated layer material composed of a layer material having a high elastic modulus is disposed in the outer layer material, By using the double-layered plate, it is possible to mix high-strength material and low-strength material, which is a useful wood material in terms of effective utilization of forest resources.

On the other hand, in countries where forest resources are abundant and diverse, and large quantities of large diameter materials can be produced, the maximum thickness dimension is set at 50 mm for the production of the laminated material, which is the basic material of the structural orthogonal laminated sheet material, and the width of the plate material is 600 to 3000 mm , And 2 ~ 10m in length, it is possible to make a long woody plate material. However, since the forest resources produced in Korea have many blind materials, limited species, and many defective low-strength materials, It is impossible.

Therefore, it is necessary to develop a manufacturing method of structural orthogonal laminated sheet material which is suitable for the wood resource produced in Korea and is excellent in the strength grade, the product standard and the workability which can be applied to domestic wooden construction.

A utility model registration No. 0334715 has been proposed as a technique similar to the above structure orthogonal plate. This laminate is composed of three or more layers of laminated wood of a small diameter material crossing each other and including a front plate layer and a two-layer plate, wherein the front plate layer and the two- .
