Abstract: A wooden house includes a roof, a wooden frame mechanism, a base, and a fixed wall panel, wherein the wooden frame mechanism with the roof mounted on the top is inserted on the base; the present invention realizes the quick mounting and dismounting of the first main cross beam and the upright post through the matching of the vertically movable wedge block and the first wedge that fixes the wedge tenon to the wedge mortise. At the same time, because the wedge mortise is connected to the common mortise, after dismounting the first main cross beam, the second wedge and third wedge are pushed into the wedge mortise through tools, to achieve the removal of the sub-cross beam from the upright post, thereby improving the efficiency of mounting and dismounting of the entire house.
