External bracket prestress inhaul cable type self-resetting special-shaped section embedded type column base joint
The external bracket prestress inhaul cable type self-resetting special-shaped section embedded type column base node comprises a special-shaped section steel pipe concrete column, brackets are arranged at the outer extending ends of the periphery of the lower portion of the special-shaped section steel pipe concrete column, inhaul cables are installed on the brackets in a prestress mode, and the outer portion of each inhaul cable is provided with a pre-stress inhaul cable. The brackets and the inhaul cables are located in the foundation and used for enhancing the connecting capacity of the column base joint. According to the embedded type column base node, the connecting capacity of the column base node and the surrounding foundation concrete can be effectively enhanced through the additionally arranged brackets and inhaul cables, so that the punching resistance and the shock resistance of the column base node are improved, and the purpose of reducing the embedded depth of the embedded type column base is achieved; and the stay rope has prestress, so that the column base node has certain self-resetting capability.
本发明提供了一种外设牛腿预应力拉索型自复位异形截面埋入式柱脚节点，包括异形截面钢管混凝土柱，所述异形截面钢管混凝土柱的下部四周外伸端设有牛腿，所述牛腿上预应力安装有拉索，所述牛腿以及拉索均处于基础中用于增强柱脚节点的联结能力。本发明可以通过外加的牛腿与拉索，有效增强柱脚节点与其周围基础混凝土的联结能力，从而提高柱脚节点的抗冲切能力以及抗震能力，从而达到减小埋入式柱脚的埋置深度的目的，并且由于拉索存在预应力可以使得柱脚节点具有一定自复位能力。
