3.1 LVL laminatedveneerlumber; LVL

A thickness of not more than 6.4mm veneer glued along the length of the member Fang Xiangshun laminae product group blanks made of structural wood composites.

3.2 Veneer LVL paralelstrandlumber; PSL

The veneer strip along the length of the member group Fang Xiangshun grain laminate glued blanks made of structural wood composites. Flitches minimum cross-sectional dimension less

To 6.4mm, the length is not less than 150 times the minimum cross-sectional dimension.

3.3 Shavings LVL laminatedstrandlumber; LSL

By the slenderness relatively large flat thin wood shavings along the longitudinal direction of the laminated member group blank glue from structural wood composites. Shavings thickness is not small

At 2.54mm, a width of not less than the thickness, length not less than 380mm.

3.4 Directional shavings LVL orientedstrandlumber; OSL

The slenderness ratio of thin shavings flat member along the longitudinal direction of the blank glued laminated group from the structural wood composites. Shavings thickness not less than

2.54mm, a width not smaller than the thickness, length not less than 190mm.

3.5 Structural wood composite structuralcompositelumber; SCL

Use veneer, veneer strips or wood shavings, etc., are arranged along the longitudinal direction of the group member preform, applying structural adhesive laminate glued together. Structures

Including wood composite laminated veneer lumber, veneer strips laminated timber and laminated wood and other wood shavings oriented.

Structural wood composite has three main directions perpendicular to each other (see Figure 1). L --- a direction parallel to the longitudinal direction of the component; X party

--- Height or width direction parallel to the member section; Y --- direction parallel to the thickness direction of the member section. Cut refers to the cutting along the grain […]
