The invention relates to a BIM-based protective fence for construction engineering, and belongs to the field of construction engineering. A sliding groove extending up and down is formed in the bottomof a frame body, a roller is rotatably arranged at the bottom of a sliding block, and an elastic piece providing outward elastic force for the sliding block is arranged between the sliding block andthe bottom wall of the sliding groove; when the elastic piece is in a natural state, the roller is located outside the sliding groove; when the roller is located in the sliding groove, the frame bodyis provided with a rotary positioning mechanism used for positioning the sliding block, and the rotary positioning mechanism comprises a rotating rod rotatably connected with the frame body; one end of the rotating rod extends into the sliding groove, and a first clamping block is arranged at the end of the rotating rod; and the length direction of the rotating rod is the same as the extending direction of the sliding groove, and a rotary clamping groove matched with the first clamping block is formed in the other end, opposite to the roller, of the sliding block. The roller on the protectivefence can be contracted, and does not need to be disassembled and assembled through a tool, so that operation of an operator is more convenient.

    本申请涉及一种基于BIM的建筑工程用防护栏,属于建筑工程领域,所述框体底部设有上下延伸的滑槽,所述滚轮转动地设置在滑块的底部,所述滑块与滑槽底壁之间设有对滑块提供向外弹力的弹性件,且弹性件处于自然状态时,所述滚轮位于滑槽外,当滚轮位于滑槽内时,所述框体设有用于定位滑块的旋转定位机构,所述旋转定位机构包括与框体转动连接的转动杆,所述转动杆的一端伸入至滑槽内且在其端部设有第一卡块,所述转动杆的长度方向与滑槽的延伸方向相同,所述滑块相对于滚轮的另一端设有与第一卡块相适配的旋转卡槽。该防护栏上的滚轮可以进行收缩,不需要通过工具进行拆卸和安装,使得操作人员操作起来更为方便。
