ABSTRACT:
A log cabin type structure formed of horizontally arranged "log" type tongued and grooved planks having notched ends which are arranged to overlap and interfit with one another to form corners, and having holes drilled through such overlapping portions for reception of a vertical metal tie rod. In accordance with a feature of the invention, the holes are preferably slightly oversize with regard to the metal tie rod, thereby facilitating assembling of the structure. The holes in alternate logs will however be slightly misaligned with one another, such misalignment being produced in one of various different ways. As the logs are bedded down with one another, the misalignment of the holes causes the holes to bind tightly on the rod and thereby procures pressure on the log ends causing them to be drawn firmly into engagement with one another in the corners. Sealing surfaces formed transversely of the log ends are thus forced into pressurized mutually sealing engagement. End fasteners at the top and bottom of the metal tie rods provide vertical pressure preventing the disassembly of the corners, and also securing the logs with their tongues and grooves in sealing engagement.
