[0002] In order to prevent people from accidentally falling into the elevator shaft, bolts are installed on the elevator shaft fence doors. After people get on and off the elevator and close the fence doors, they must insert the bolts as required to avoid people slipping, stepping on air, and falling accidents from heights. Therefore, protective fences are used to protect the elevator shaft opening to ensure construction safety. When installing the protective fence, expansion bolts are usually used to fix the four corners and cement mortar is used to seal the bottom gap. Due to the advantages of expansion bolts fixing and mortar sealing the bottom gap, which are easy to obtain materials and simple to understand, they are widely loved by workers.
