  • Patent number: 4909012
    Abstract: A method of wall construction using a compressive fastener for log building construction which acts to continuously maintain pressure between individual logs in a building wall which includes a plurality of logs in stacked configuration. Logs are joined by boring a row of bores in the top log and counterboring each bore as a receptacle for the head of the fastener and a concentric spring assembly, the bores being larger than the shank of the fastener as well as the spring assembly to allow the fasteners to freely vertically expand and contract. Once the bored log is stacked and aligned on the log immediately below it, the fasteners are inserted into the boreholes and driven or tightened until the spring assembly is partially compressed and the fastener heads are below the upper surface of the upper log. The compressive fasteners pull the logs together to overcome long-term shrinkage and the continuous expanding and contracting caused by climatic changes.
