Tukipalkkeja

Tukipalkkeja are structural members used in buildings and other constructions to support loads and transfer them to supporting elements. They are horizontal members that carry loads from above—such as joists, rafters, or floors—and transfer them to vertical supports like walls or columns. They help control span, reduce deflection, and provide stability.

Common materials include timber (solid lumber, engineered wood such as LVL or glulam), and steel. In some cases concrete or composite sections are used for heavy loads or long spans. The choice depends on load, span, environmental conditions, and cost.

Proper sizing and spacing follow structural design calculations and local building codes. Connections are critical: brackets, joist hangers, screws or bolts ensure transfer of shear and moment. Wood tukipalkkeja require moisture protection and rot resistance; steel require corrosion protection. Bearings at supports should be adequate to avoid excessive settlement.

Used in floors, roofs, mezzanines, bridges, industrial platforms, and temporary shoring, tukipalkkeja can be standard stock sizes or custom-cut. In some contexts tukipalkkeja may also refer to decorative or non-structural supports, but in standard usage they carry structural loads.
