The invention belongs to the technical field of aircraft structure design, and discloses a multipurpose detachable aircraft floor structure which is composed of a rectangular double-ground-rail type blocking plate, two Z-shaped supports, a floor, three L-shaped supporting pieces, a stop ground rail, four limiting bolts and eight limiting blocks. The structure solves the problems that when configuration transformation is conducted on the top structure of the large opening of the fuselage, the number of related components is large, installation is tedious, and function compatibility is not high, the structure integration degree is high, connection is reliable, the adaptation degree is good, and the time needed for aircraft configuration reloading is greatly shortened compared with the time needed for aircraft configuration reloading in an existing structure form.

    本发明属于飞机结构设计技术领域,公开了一种多用途可拆卸的飞机地板结构,其由一个矩形的双地轨式堵板、两个Z形支座、一个地板、三个L形支撑件、一个止动地轨、四个限位螺栓、八个限位块组成。本发明解决了机身大开口顶部结构进行构型变换时,涉及零组件数量较多、安装较为繁琐、功能兼容性不强的问题,本发明的结构集成度高、连接可靠、适配度好,飞机构型换装所需时间较以往结构形式大大减少。
