Abstract
The present invention discloses a log cabin construction using naturally tapered logs with multi-beveled interlocking notches located at the end of each log. The interlocking notches serve to form a tight locking connection at the cornering of the structure where the logs overlap one another. The interlocking notches are composed substantially of heartwood, which serves to reduce settlement and maintain a tight connection over time. The measurements for the interlocking notches are a function of the dimensions of the logs used. The log cabin construction further employs anti-settling blocks which are disposed between the logs of the structure. In the preferred embodiment, the anti-settling blocks are positioned in aligned recesses which are present in the logs that compose the structure. Accordingly, the presence of the interlocking-notch cornering system and the anti-settling blocks combine to minimize the negative effects of settling on the structure while providing an aesthetically pleasing appearance.
