Abstract
A first story log house material is adhered to a base with a coach bolt and succeeding log materials after a second story are piled up in turn with clamping bolts. A coach bolt or a clamping bolt has a height corresponding with one long thickness and is equipped with a nut portion and a wahser. This method of assembling log walls for the log house eliminates the accumulated shrinkage for the log wall during the drying period. Thus, by the present invention, it is now not necessary to prepare some large size of a side adjusting device and also to reserve some large settling space, both of which are unavoidable in prior art.

A method of assembling log walls for a log house wherein a base log material is held to a base with a coach bolt and succeeding logs are piled up in turn with clamping bolts, comprising the steps of:
- providing a coach bolt having a height corresponding with that of said base log material;
- providing clamping bolts having a height corresponding to respective succeeding logs;
- providing the coach bolt with an additional threaded wood screw at at its bottom part for respective succeeding logs;
- providing on a top part of said coach and said clamping bolts, a nut portion built with a thread to accept the bolt portion of a clamping bolt normal screw;
- providing as one body a washer between the bolt portion and the nut portion on said carriage bolt and on said clamping bolt;
- drilling a bolt insertion hole through the respective succeeding logs into which the bolts are to be inserted;
- screwing the clamping bolt portions used in the respective succeeding logs into the nut portions used in lower succeeding bolts for continual coupling the respective succeeding log material;
- and
- wherein each of said washers presses down on a log beneath it.
A log house clamping bolt, said bolt comprising in the combination:
- a bolt length corresponding to the length of a respective single log;
- a threaded portion with a normal screw located in a bottom portion of said bolt;
- a nut portion built as a single body with the bolt located at the top portion of said bolt;
- a washer portion formed between the bolt portion and nut portion;
- wherein the threaded portion of said nut is exactly threaded to accept another identical bolt portion.
A log house coach bolt, said bolt comprising in combination:
- a bolt length corresponding to the length of a respective single log;
- a threaded portion with a wood screw located in a bottom portion of said bolt;
- a nut portion built as a single body with the bolt located at the top portion of said bolt;
- a washer portion formed between the bolt portion and nut portion;
- wherein said washer has a larger diameter than a bolt insertion hole in a log;
- and
- wherein the threaded portion of said nut is exactly threaded to accept an identical thread clamping bolt portion.
