Fixed buckle device for increasing section of I-shaped steel beam

An I-shaped steel beam cross section increasing fixing buckle device belongs to the field of building construction and is composed of a steel support, a movable supporting component and a double-threading nut. The steel supporting plate and the movable supporting component are connected through the double-threading nut and are fixedly connected with the I-shaped steel beam and the welded steel component. According to the invention, double connection and fixation of construction by a traditional steel structure section increasing method are realized, and the stability and safety of connection are improved; operation is convenient, cost is low and efficiency is high; and only one-time hoisting in-place is needed, so that the cost is reduced and the energy is saved. 一种工字钢梁增大截面固定卡扣装置，属于建筑施工领域，它由钢托、可动支撑构件、双套丝螺母组成；钢托板和可动支撑构件通过双套丝螺母连接，并与工字钢梁和加焊钢构件固定连接。本发明实现了传统钢结构增大截面法施工双重连接与固定，增加了连接的稳定性与安全性；操作便捷，成本低且效率高；只需要一次吊装就位即可，实现了成本降低与能源节约。
