Automatic alarm device for steel support
The invention belongs to the technical field of deep foundation pit steel supports in the field of building construction, and particularly discloses an automatic alarm device for a steel support. The automatic alarm device comprises a triangular frame installed on a cast-in-situ bored pile, a steel enclosing purlin located on the triangular frame, the steel support fixedly connected with the steel enclosing purlin, and a cable-stayed system connected with the steel support and the upper portion of the cast-in-situ bored pile. An alarm is arranged on the cable-stayed system, when the steel support deforms and inclines downwards, a steel wire rope is tensioned firstly to pull a lower adjusting bolt, and therefore a steel wire is pulled; and due to the fact that a first conductive copper sheet is fixedly connected with the steel wire, a second conductive copper sheet is fixedly connected with an upper adjusting bolt, the first conductive copper sheet moves downwards to touch the second conductive copper sheet to form a passage, a loudspeaker rings, and a flashing warning lamp flashes to remind workers to pay attention to safety.
本发明属于建筑施工领域的深基坑钢支撑技术领域，具体公开一种钢支撑自动报警装置，包括安装于钻孔灌注桩上的三角架，位于三角架上的钢围檩，与钢围檩固定连接的钢支撑，以及连接钢支撑与钻孔灌注桩上部的斜拉系统，通过将报警器设置于斜拉系统上，当钢支撑发生变形向下倾斜时，钢丝绳首先张紧拉动下部调节螺栓从而拉动钢丝，由于第一导电铜片与钢丝固定连接，第二导电铜片与上部调节螺栓固定连接，从而第一导电铜片向下运动触碰第二导电铜片形成通路，使高音喇叭响动，闪烁警示灯闪亮提醒工作人员注意安全。
