The invention discloses a floor panel structure of an aircraft goods hold. The sealing structure comprises a panel, a sealing gasket, a fastener gasket, a countersunk head fastener and a panel insert,a plurality of framework connecting holes are formed in the panel; the panel insert is arranged in the framework connecting hole; the countersunk head fastener and the fastener gasket are arranged inthe panel insert; the sealing gasket is arranged on the lower surface of the panel. According to the invention, the structural form of the aircraft goods compartment floor panel is simplified; the components are integrated into a modular configuration; on the premise that the structural forms are the same; the materials and the thicknesses of the carbon fibers and the core material in the panel are adjusted; the aircraft goods compartment floor panel can meet the requirements of different aircraft types according to the length of the panel insert and the length of the countersunk head fastener, so that the research and development time of the aircraft goods compartment floor panel is greatly shortened, the design efficiency is improved, the research and development cost is reduced, and meanwhile the aircraft goods compartment floor panel is high in structural bearing capacity, rigidity and universality, light in weight and easy to produce and assemble.

    本发明公开了一种飞机货舱地板面板结构,包括面板、密封垫、紧固件垫圈、沉头紧固件以及面板镶嵌件,所述的面板开设有若干骨架连接孔,所述的面板镶嵌件设置在所述的骨架连接孔内,所述的沉头紧固件、紧固件垫圈设置于面板镶嵌件内,所述的密封垫设置在面板的下表面,本发明简化了飞机货舱地板面板的结构形式,将其整合为为模块化构型,使得在结构形式相同的的前提下,通过调整面板中碳纤维和芯材的材料、厚度,以及面板镶嵌件、沉头紧固件的长度,可以适应于不同机型的要求,使得飞机货舱地板面板的研发时间大为缩短,提高了设计效率,降低了研发成本,同时结构承载能力强、刚度大、重量轻、易于生产和装配、通用性强。
