Abstract
The invention discloses a bolt connection node for a bamboo/wood frame structure in which a beam and a column are clamped outside a steel plate, and belongs to the field of civil engineering. The bolt connection node for the bamboo/wood frame structure in which the beam and the column are clamped outside the steel plate comprises the beam, the column, the connecting steel plate and bolts. The connecting mode that the beam and the column cover the connecting steel plate is adopted, second bolt holes are formed in the connecting steel plate, first bolt holes are formed in both the beam and the column, and the centers of the first bolt holes are aligned with the centers of the second bolt holes in the corresponding positions of the connecting steel plates. The bolts sequentially penetrate through the second bolt holes of the connecting steel plates, the first bolt holes of the beam or the column and the second bolt holes of the connecting steel plate and then are anchored with nuts into a whole. Friction force shearing resistance is generated by applying precompression to the connecting steel plate by the bolts. The bolt connection node has the advantages of being clear in force transmission, high in shearing resistance, convenient to construct and easy to machine.
