Problems solved by technology

It has a high density, is relatively bulky, has poor elasticity and nail grip, and is easy to break and crack. Usually, the surface needs to be hot-pressed and sealed around the edges during processing. Due to the unequal stress on both sides after heating, it is easy to warp and deform. And it is very easy to be affected by moisture and swell and cause mildew and rot, which seriously affects the quality and service life of the product

Embodiment Construction

[0007] Below in conjunction with accompanying embodiment the process for making of the present invention is described in detail:

[0008] 1. Panel production: Use fir squares with a size of 4-6cm×5-12cm to plan and determine the thickness through four-sided planing, and finger-join the planed squares to lengthen to about 2480mm through a comb-tooth tenon jointing machine; Cut the finger-joined strips into strips with a thickness of 4 to 4.5mm and a length of 2480mm through a multi-blade saw, and then use a jigsaw mechanism to cut the strips of the same thickness into a panel with a length and width of 2480×1245mm1 .

[0009] 2. Middle board production: use fir squares with a specification of 4-6cm×5-12cm to plan and determine the thickness through four-sided planing, and finger-join the planed squares to lengthen to about 1245mm through a comb-tooth tenon jointing machine; Next, cut the finger-joined strips into strips with a thickness of 9.4mm and a length of 1245mm through ...

Abstract

The invention provides three-layer solid wood materials of pure Chinese fir and its preparation method. It is characterized in that: after planed and thickness defining, complete tenon process and finger joint of the Chinese fir square stocks. Then, dissect them into slice strips along their length direction and put the slice strips with the same lengths together to form plates. Based on the wood texture, press them to 18mm three-layer solid wood plates through vertically crossed by sizing layer-by-layer. The products have compact structure and light texture, eliminate the wood internal stress, have characteristics of large intensity, good flexibility, corrosion resistance and are moisture proof and uneasy to distort and crack.

Description

Technical field: [0001] The invention relates to the field of laminated timber, in particular to a pure fir three-layer solid wood laminated timber and a manufacturing method thereof. Background technique: [0002] At present, the board materials of wood products are mostly particleboard (P.B), midi board (F.B) and medium fiberboard, and their main components are bonded and pressed by wood chips and glue. It has a high density, is relatively bulky, has poor elasticity and nail grip, and is easy to break and crack. Usually, the surface needs to be hot-pressed and sealed around the edges during processing. Due to the unequal stress on both sides after heating, it is easy to warp and deform. And it is very easy to be affected by moisture and expand and cause mildew and rot, which seriously affects the quality and service life of the product. Invention content: [0003] The purpose of the present invention is to solve the above-mentioned problems, aiming to provide a pure woo...
