Connecting joint of existing concrete column and heightened steel column
The invention relates to a connecting joint of an existing concrete column and a heightened steel column. The connecting joint involves the existing concrete column, the heightened steel column, pre-buried anchor bolts, a column foot bottom plate, a shear key, a reinforcing short column, anchor plates, double nuts and a shear groove; the bottom end of the heightened steel column is connected withthe column foot bottom plate through welding; the reinforcing short column is arranged on the upper portion of the existing concrete column, the shear groove is formed in the top of the reinforcing short column, the shear key is arranged in the shear groove, and the shear key is located in the center of the column foot bottom plate and connected with the column foot bottom plate through welding; and the pre-buried anchor bolts are pre-buried in the reinforcing short column, are arranged at the top end of the existing concrete column and are connected and fixed with the column foot bottom platethrough the double nuts and the anchor plates. The connection joint of the existing concrete column and the heightened steel column has the beneficial effects that the construction difficulty is reduced while the existing concrete column and the heightened steel column are stably connected, so that the construction process is simple, safe and reliable, and the connection joint has the characteristics of clear force transmission, simple design and the like.
本发明涉及既有混凝土柱与加高钢柱连接节点，包括既有混凝土柱、加高钢柱、预埋锚栓、柱脚底板、抗剪键、加固短柱、锚板、双螺母和剪力槽；加高钢柱底端与柱脚底板通过焊接连接；既有混凝土柱上部设有加固短柱，加固短柱顶部设有剪力槽，剪力槽内设有抗剪键，抗剪键位于柱脚底板中心处并与柱脚底板通过焊接连接；预埋锚栓预埋在加固短柱内，预埋锚栓设于既有混凝土柱顶端，并且预埋锚栓与柱脚底板通过双螺母和锚板连接固定。本发明的有益效果是：本发明的既有混凝土柱与加高钢柱连接节点，使得既有混凝土柱与加高钢柱稳固连接的同时，降低了施工难度，使得施工过程简单、安全、可靠，并且具有传力明确、设计简单等特点。
