The foundation is formed by pouring concrete with the strength not lower than C25.
The size of the groove is consistent with that of the steel plate.
The steel plate is made of steel with yield strength not lower than 340MPa, and is buried into a corresponding position when the foundation is poured to form a whole with the foundation.
The vertical preformed hole and the horizontal preformed hole are respectively arranged on the periphery of the bamboo column and the foundation and are arranged in a staggered mode, and the diameter of each hole is 18-20 mm.
The strength grade of the bolt is not lower than 8.8 grade, the surface of the bolt is galvanized, and the nominal diameter of the bolt is 1.0-1.5 mm smaller than that of the longitudinal preformed hole and that of the transverse preformed hole.
The bamboo column is simple in structure and convenient to use, can strengthen the connection between the bamboo column and the foundation, and obviously improves the integral bearing performance and the anti-seismic performance of a structural building. The utility model effectively utilizes the support of the steel plate, enhances the integrity of the structure through the bolt, not only improves the bearing capacity of the structure, but also has less appearance transformation of the column, reduces the construction difficulty, can be used for reinforcing the bamboo-wood structure of the historic building, and can also improve the bearing performance and the anti-seismic performance of the modern light bamboo-wood structure.
