本发明公开了一种用于高空施工的支撑装置，包括两个用于支撑脚部的脚踏结构、连接所述两个脚踏结构的连接结构，所述连接结构包括支撑部、两个分别连接所述脚踏结构和支撑部的连接部，所述连接结构横跨横梁并且所述支撑部支撑于所述横梁上，所述两个连接部分别位于所述横梁的左右两侧，所述脚踏结构固定于所述连接部沿横梁向下方向延伸的一端。本发明的有益效果在于在单根横梁高空施工作业中为人体坐式施工提供双脚的支撑装置，避免人体双脚长时间悬空产生晕眩感，造成危险，使得高空施工作业安全性更高。

The invention discloses a supporting device for high-altitude construction. The supporting device for high-altitude construction comprises two pedal structures for supporting feet and a connecting structure for connecting the two pedal structures, wherein the connecting structure comprises a supporting part and two connecting parts correspondingly connected with the pedal structures and the supporting part; the connecting structures stretch across a cross beam, the supporting parts are supported on the cross beam, the two connecting parts are located on the left side and the right side of the cross beam correspondingly, and the pedal structures are fixed to the ends, extending downwards along the cross beam, of the connecting parts. The supporting device for high-altitude construction has the beneficial effects that the supporting device for two feet is provided for human body sitting type construction in single-beam high-altitude construction operation, and the situation that the two feet of the human body are suspended for a long time to generate dizziness and cause danger is avoided, so that the safety of high-altitude construction operation is higher.
