Concrete underground protective door
The invention relates to the technical field of civil air defense engineering equipment, in particular to a concrete underground protective door which comprises a door body, a door frame, a locking assembly and a sealing assembly, the door body is connected with the door frame through hinges, the door body comprises a metal frame and a concrete structure, and the metal frame is filled with the concrete structure; a fiber composite material is arranged in the concrete structure, the fiber composite material is arranged in a double-layer and two-way mode, and the concrete structure is rotationally connected with a manual rotating disc capable of opening or closing the locking assembly and the sealing assembly at the same time. The fiber composite material is arranged in the concrete structure, the tensile strength, the compression resistance, the shear resistance and other performance of concrete can be improved, and therefore the impact resistance of the concrete is improved, and the effect of improving the impact resistance of the protective door is achieved.
本申请涉及人防工程器械设备的技术领域，尤其是涉及一种混凝土地下防护门，其包括门体、门框、闭锁组件及密闭组件，门体与门框通过铰页连接，门体包括金属边框和混凝土结构，混凝土结构填充在金属边框内，且混凝土结构内设置有纤维复合材料，纤维复合材料双层双向设置，混凝土结构上转动连接有能够同时开启或关闭闭锁组件和密闭组件的手动转盘。混凝土结构内设置有纤维复合材料，能够提高混凝土的抗拉、抗压、抗剪等性能，从而增加混凝土的抗冲击性能，因此本申请具有提高防护门抗冲击力的效果。
