bolblokke

Bolblokke, translating to bolt blocks in Danish, refer to modular components used in construction and engineering to provide anchor points for bolts and studs. The term is common in Danish-language technical literature and describes blocks designed to transfer loads from fasteners into the surrounding substrate while maintaining alignment and ease of assembly.

There are several common forms of bolblokke. Steel bolblokke are machined blocks with threaded holes or captive nuts, used where high strength and precise bolt alignment are required. Concrete bolblokke are precast or cast-in-place blocks that include embedded sleeves or channels to guide bolt placement and distribute loads into the concrete or masonry. Additional variants may be made from plastic or composite materials for non-load-bearing applications or specific environmental conditions.

Applications for bolblokke include machinery bases, structural connections, scaffolding anchors, foundation plinths, and mounting points for equipment and frames. In many projects, bolblokke are embedded in concrete during casting or installed between a foundation and the supported structure to ensure proper load transfer and repeatable bolt locations.

Design and installation considerations focus on load rating, substrate condition, corrosion risk, and required alignment tolerance. Selection is based on the anticipated forces, environmental exposure, and whether the block will be exposed to moisture or chemicals. Installation typically involves positioning the block accurately, aligning bolt holes, using grout or epoxy where appropriate, and tightening bolts to specified torque. For steel bolblokke, surface treatments such as galvanization may be used to improve durability.

Standards and guidelines for bolblokke vary by region and application, and engineers typically refer to local structural or mechanical engineering standards when specifying them.
