Multi-degree-of-freedom weak connection joint additionally provided with elevator steel shaft
The invention discloses a multi-degree-of-freedom weak connection joint additionally provided with an elevator steel shaft. The multi-degree-of-freedom weak connection joint comprises a rigid end plate fixedly arranged on an existing building and a mounting plate with one end fixedly connected with the steel shaft, wherein two lug plates arranged side by side are fixed to the rigid end plate; a main shaft is fixed between the two lug plates in a penetrating mode; the other end of the mounting plate is arranged on the main shaft in a sleeving mode and located between the two lug plates; and a compression spring is clamped between each lug plate and the mounting plate and arranged on the main shaft in a sleeving mode. By adopting the arrangement, the joint internal force caused by the displacement difference in the vertical direction and the horizontal direction can be effectively released, and the connection reliability of an additionally-arranged elevator can be ensured.
本发明公开了一种增设电梯钢井道的多自由度弱连接节点，包括固定设置在既有建筑上的刚性端板、一端与钢井道固定连接的安装板，刚性端板上固定有两并排设置的耳板，两耳板之间穿设固定有一主轴，安装板的另一端套设在所述主轴上，并位于两耳板之间，每块耳板与安装板之间均夹设有压缩弹簧，且压缩弹簧套设在主轴上。通过采用上述设置，本发明不仅可以有效地释放竖直向和水平向位移差所引起的节点内力，而且还能保证增设电梯的连接可靠性。
