PROBLEM TO BE SOLVED: To solve the problem wherein with the development of foreign trade, introduction of inexpensive foreign-made materials progresses, domestic material costing high is kept distance by people so that forestry is extremely declined by providing an improved building method using a large amount of small wood providing forestry expenses. SOLUTION: In this building method, a small square timber 1 having a dovetail tenon 2 and a dovetail hole 3 worked at both ends thereof has upper surface, lower surface right and left sides provided with a slippage preventing groove 5 and connected to a connecting plate 4 and a connecting rod 6 to be united in one body. The thus worked flat square timbers (Fig. 3) are mutually linked and connected to be stacked. This is the T, L, R, E building method for a column-less wooden building having small square timbers linked and connected to be freely contracted and enlarged. The advantages of the building method are that since this building is column-less and horizontal type, it is good for moisture drying, always air-tightness is kept, comfortability is attained, and further linking and connection of small square timbers can achieve good durability and present building beauty, and a large amount use of small timbers can contribute to the promotion of forestry and reducion of CO2.
