Arc-shaped flange cross column steel embedded part and construction method thereof
The invention provides an arc-shaped flange cross column steel embedded part. The arc-shaped flange cross column steel embedded part comprises a lower anchoring part and a steel pipe column. The lower anchoring part comprises a plurality of annular positioning plates and a plurality of L-shaped anchor bolts which are arranged at intervals in the vertical direction, and each anchor bolt comprises a vertical section penetrating through and fixedly connected with the corresponding positioning plate and a horizontal section facing the axis of the corresponding positioning plate; the lower anchoring part is supported on a bearing column and is fixed by pouring a positioning concrete section; an anchor plate is arranged at the lower end of the steel pipe column, a plurality of strip-shaped notches are formed in the position, close to the anchor plate, of the lower portion of the steel pipe column, each strip-shaped notch is arranged around the axis of the steel pipe column, arc-shaped flanges are formed between any two adjacent strip-shaped notches, and the anchor plate is supported on the positioning concrete section and fixedly connected with the anchor bolts. The arc-shaped flange cross column steel embedded part and a construction method thereof has the beneficial effects that pre-burying is conducted from the middle, and compared with pre-burying from a foundation in the past, the construction efficiency is improved; the arc-shaped flanges can obtain larger section performance, improve bearing capacity and are matched with the circular section of the upper portion of the steel pipe column, stress concentration cannot occur during stress transmission, and stress is more reasonable.
本发明提供一种弧形翼缘十字柱钢埋件，包括：下锚固件，其包括沿着竖直方向间隔设置的多个圆环形定位板和多个L形锚栓，锚栓包括贯穿并固定连接各定位板的竖直段和朝向定位板轴线的水平段，下锚固件支撑于承载柱且通过浇筑定位混凝土段被固定；以及钢管柱，其下端设有锚板，钢管柱下部靠近锚板设有多个条形缺口，各条形缺口环绕钢管柱轴线设置，任意相邻两条形缺口之间形成一弧形翼缘，锚板支撑于定位混凝土段上且与各锚栓固定连接。本发明的有益效果：由中部进行预埋，相较以往从基础开始预埋，提高施工效率；弧形翼缘能够获得更大的截面性能，提高承载力，与钢管柱上部圆形截面匹配，受力传递不会出现应力集中，受力更加合理。
