Concrete civil air defense door and production process thereof
The invention discloses a concrete civil air defense door and a production process thereof, and belongs to the technical field of civil air defense door processing. The concrete civil air defense doorcomprises a door frame, wherein two steel bar frameworks with the same structure are sequentially placed in the door frame, and a sandwich mechanism used for separating the two steel bar frameworks is placed on the portion, positioned between the two steel bar frameworks, of the door frame; the sandwich mechanism comprises two steel plates, a cavity is formed between the two steel plates, a discharging cylinder is jointly and fixedly arranged in the middle of the two steel plates, and the discharging cylinder is used for communicating the two steel bar frameworks; and guide plates are symmetrically and fixedly arranged on the two sides of the door frame, and a guide groove is formed in the position, corresponding to the corresponding guide plate, of each steel plate. The civil air defensedoor has the advantages that the weight of the civil air defense door is reduced, and the opening and closing of the civil air defense door are facilitated.
本发明公开了一种混凝土人防门及其生产工艺，属于人防门加工技术领域，其包括门框，门框内依次放置有两个结构相同的钢筋骨架，所述门框位于两个钢筋骨架之间放置有用于将两个钢筋骨架分开的夹层机构；所述夹层机构包括两块钢板，两块钢板之间形成空腔，两个钢板的中部共同固设有一个下料筒，下料筒用于将两个钢筋骨架之间连通，门框的两侧对称固设有导向板，钢板对应导向板的位置开设有导向槽，本发明具有减少人防门的重量、便于人防门的开启和关闭的效果。
