The invention belongs to the technical field of building construction, and particularly relates to an elevator pit personnel accidental falling protection structure which comprises a silk thread safety net and a frame a arranged on the edge of the silk thread safety net, a plurality of infrared sensors are obliquely installed on the upper surface of the frame a, and emergent light beams of the infrared sensors are all emitted to the upper wall of an elevator shaft. A controller connected with the infrared sensor is arranged on the frame a, a lifting mechanism is arranged on the lower surface of the frame a, a metal safety net connected with the lifting mechanism is arranged below the frame a, and a trigger piece is arranged in the metal safety net; the triggering piece comprises a safety air bag assembly installed in the middle of the metal safety net, sponge columns are installed in holes of the metal safety net, and the two ends of each sponge column extend out of the holes of the metal safety net respectively. The distance between the two layers of safety nets can be reduced along with the increase of the falling height of people, and the enough distance is reserved between the two layers of safety nets, so that the falling people are prevented from being clamped by the silk thread safety nets.
本发明属于建筑施工技术领域,具体涉及一种电梯底坑人员意外坠落保护结构,包括丝线安全网以及设置在丝线安全网边缘的边框a,边框a的上表面倾斜安装有多个红外传感器,红外传感器的出射光束均射在电梯井的上壁,边框a上设置有与红外传感器连接的控制器,边框a的下表面设置有升降机构,边框a的下方设置有与升降机构连接的金属安全网,金属安全网的内部设置有触发件;触发件包括安装在金属安全网中部的安全气囊总成,金属安全网的孔中均安装有海绵柱,海绵柱的两端分别延伸出金属安全网的孔。本发明可以随人员坠落高度的增加来减小两层安全网的间距,且两层安全网留出足够的间距,防止丝线安全网卡住坠落人员。
