[0002] At present, in the design and construction engineering of ancient buildings, the column is usually directly placed on the underlying drum pier according to the ancient methods of the Ancient Building Methods, the Ancient Building Methods and the Ancient Building Regulations. Although this method is beneficial to the moisture and corrosion resistance of the wood structure, it greatly reduces the ability of the structure itself to resist horizontal force, especially in structures with a large height-width ratio, this problem is particularly prominent. Due to this limitation, the height of the ancient building wood structure is greatly limited, and the wood consumption of the ancient building wood structure is relatively large compared with the modern wood structure, which is not economical. If the material consumption is the same, the safety of the ancient building wood structure is also relatively small compared with the modern wood structure. Therefore, how to provide a simple, easy-to-operate, low-cost, and greatly improved wood structure column foot and foundation fixing connection structure with bending, shearing, tensile and compressive stress performance has become a technical problem that needs to be further improved and optimized in the field of building construction.
