Processing method of crosswise laminated plate

Abstract

The invention relates to a processing method of a crosswise laminated plate, which comprises the steps of laminate preparation, compound modifier preparation, surface layer laminate modification and reinforcement, laminate finger jointing, laminate-plate gluing, assembling, pressing and post-processing. A surface layer laminate modification and reinforcement process comprises the steps of putting surface layer laminates into a closed pressure tank for vacuum pumping treatment and then performing compression for reinforcement to the treated laminates; and an assembling and pressing process comprises the steps of putting the modified and reinforced laminates on a surface layer, assembling the laminates in a manner that the texture directions of adjacent laminates are mutually perpendicular, putting the assembled laminates into a press for cold pressing and applying lateral pressure at the same time. The processing method has the advantages that not only can fast growing wood at home be used for producing crosswise laminated plates, but also the performance of the produced crosswise laminated plates is excellent, the main mechanical property indexes of the products can reach and exceed the property indexes of similar domestic and overseas products, the products are endowed with multiple functions such as flame retarding and antibacterial functions, the utilization scope of the fast growing wood is expanded, and the development of domestic wood structure buildings towards safe and high-quality high-rise buildings is promoted.

Description

[0001] technical field [0002] The invention relates to a method for manufacturing cross-laminated boards, which belongs to the technical field of wood-based panel manufacturing technology. [0003] Background technique [0004] Compared with reinforced concrete and other building forms, wood structure buildings have the advantages of energy saving, environmental protection, renewable wood, and good earthquake resistance. In North America, Europe, Japan and other countries, wood structure buildings, especially residential buildings, are widely used. my country's ancient wooden structure buildings have a long history and are unique. After the 1970s, due to the problem of timber resources, domestic wooden structure buildings were forced to stagnate. Since my country became a member of the WTO, the volume of timber imports has increased year after year. Canada and other countries have vigorously promoted new types of wooden structures in China, and have gradually obtained go...

Problems solved by technology

[0006] However, the current domestic wood structure code stipulates that the maximum number of floors of light wood structure buildings is only 3 floors, which greatly limits the development of wood structure buildings in China

There are two main reasons. One is that the design and construction technology of domestic modern wood structure buildings are relatively backward; , now it is only used to produce decorative panels, but not used in wood structure buildings, leading to the fact that domestic wood structure buildings mainly use foreign wood, and the cost is relatively high
