The invention relates to the technical field of hull manufacturing, in particular to a prefabricated hatch structure of a glass fiber reinforced plastic ship. A deck is arranged, and the deck is provided with a prefabricated hatch used for being communicated with the interior of a cabin. The prefabricated hatch structure is characterized in that the prefabricated hatch is provided with a prefabricated hatch plate; a square hatch is formed in the middle of the prefabricated hatch plate; a square groove for placing a hatch cover is formed in the hatch plate around the square hatch; water guide holes communicated with the interior of the cabin are formed in the hatch plate at the two ends of any side of the bottom of the square groove; an avoiding tangent plane is arranged on the hatch plateon the inner side of the groove corresponding to each water guide hole; and the inclination angle between each avoiding tangent plane and the adjacent side face of the hatch plate is 45 degrees. The installation space for installing the stainless steel water guide pipes through the water guide holes is enlarged through the avoiding tangent planes. The prefabricated hatch structure has the advantages of being simple in structure, good in water guide effect, convenient to install, large in operation space and the like.

    本发明涉及船体制造技术领域,具体地说是一种玻璃钢船预制舱口结构,设有甲板,甲板上设有用于与船舱内部相连通的预制舱口,其特征在于所述的预制舱口设有预制舱口板,预制舱口板的中部设有方形舱口,方形舱口周围的舱口板上设有用于放置舱口盖的方形凹槽,方形凹槽底部任意一边的两端的舱口板上设有与船舱内相连通的导水孔,每个导水孔对应的凹槽内侧的舱口板上设有避让切面,所述的避让切面与相邻舱口板侧面的倾斜角度为45°,通过避让切面实现导水孔安装不锈钢导水管的安装空间增大,具有结构简单、导水效果好、安装方便、操作空间大等优点。
