rivikiinnityksen

Rivikiinnitys, literally a row fastening, is a mechanical fastening method used in engineering and construction to secure components by placing multiple fastening points along a joint in regular rows. The core idea is to distribute loads more evenly and to provide redundancy along the connection, so that the failure of a single fastener does not compromise the entire joint. The exact practice can vary by industry and application, but it typically involves aligning holes or slots in the parts to be joined and installing fasteners at uniform intervals.

Common implementations use rivets, bolts, or screws arranged in one or several parallel lines along the joint. Precise alignment and consistent spacing or pitch are important to ensure even load transfer and to minimize stress concentrations. Preparation steps may include surface cleaning, drilling or punching of holes, use of templates or jigs for accuracy, and, where appropriate, sealants or gaskets to improve sealing and corrosion resistance. Materials involved range from metals such as steel and aluminum to composites or wood, depending on the application, with attention to material compatibility and protective coatings to prevent corrosion.

Applications are found in areas requiring long joints and high load-bearing capacity, such as aircraft skin assemblies, ship hulls, heavy machinery frames, and architectural cladding. Advantages of rivikiinnitys include improved load distribution, durability, and inspectability along the joint. Potential drawbacks are higher labor requirements, the need for precise fabrication, and increased weight or complexity compared to single-point connections.
