Title:
BAMBOO JOINT TYPE ENERGY-DISSIPATION CONCRETE-FILLED STEEL TUBE COLUMN BASE JOINT AND MOUNTING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/062284
Kind Code:
A1
Abstract:
A bamboo joint type energy-dissipation concrete-filled steel tube column base joint, comprising a double-steel-tube assembly (1), a connecting assembly (2), and a foundation assembly (3). The double-steel-tube assembly (1) comprises a lower outer steel tube (11), a lower inner steel tube (12), an upper outer steel tube (13), and an upper inner steel tube (14); the connecting assembly (2) comprises an inner supporting piece I (21), an inner supporting piece II (22), a connecting cylinder (23), and an energy dissipation device (24) with folds; the foundation assembly (3) comprises an upper foundation steel plate (31), a lower foundation steel plate (32), and a concrete foundation (33); the upper foundation steel plate (31) is provided with a hole in the center, and the lower outer steel tube (11) passes through and is fixed to the upper foundation steel plate (31); the lower outer steel tube (11) is fixed on a horizontal plate (2203). The inner supports are designed in the double-steel-tube column to form a bamboo joint effect, the overall strength of the column is improved, moreover, the strength of a column base is enhanced by means of the inner support design, inner supports are provided at the column base, and inner steel tubes are prevented from buckling; the energy dissipation device (24) with the folds serves as an energy absorption device, earthquake energy is consumed by folding and unfolding of steel pipe walls during an earthquake, the integrity of the column and the foundation is guaranteed, and the earthquake resistance is improved.
