2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS 2.4.2 Multiple-glued GLVL columns Multiple-glued GLVL can be used in larger cross sections for load-bearing columns in post and beam structures. They are glued together from several LVL-P or, in some cases, LVL-C laminas. The column cross sections can be tailored project-specifically, but for optimized material efficiency the standard widths or 5-10 mm smaller widths are recommended. Column thicknesses are derived from multiple sanded LVL laminas. • Recommended column thicknesses: 84, 90, 96, 108, 120, 133 and 144 mm • Recommended column widths: 200, 225, 240, 260, 300, 360, 450 and 600 mm Massive multiple-glued GLVL columns are possible for heavy-duty structures up to glulam beam dimensions. The maximum width is usually 400 mm, but the thickness can be up to 2000 mm. In visible applications, massive multiple-glued GLVL cross sections have the advantage that they are not sensitive to cracking in dry conditions. However, for visible applications the sanding and lamina specifications must be separately agreed with the supplier to ensure clean veneer surfaces. Figure 2.60.
