Technical Field
[0001] The utility model relates to the technical field of hull machinery manufacturing, in particular to a fiberglass reinforced plastic boat deckhouse connection structure. Background Art
[0002] Currently, the connection between the deckhouse and deck of fiberglass-reinforced plastic (FRP) boats is typically achieved by creating an inward flange at the bottom of the deckhouse. The deckhouse and deck are secured with screws, and then a connecting layer is applied internally and externally. After the outer connecting layer cures, it is polished and smoothed, sprayed with a gel coat, and then water-polished until the gel coat surface is as bright as the deckhouse. Due to the low interlaminar shear strength of FRP and the complex operating conditions at sea, the connection between the deckhouse and deck is prone to fine cracks, which can lead to leakage. Furthermore, for aesthetic reasons, the outer connecting layer requires a detailed surface finish, which is labor-intensive. Utility Model Content
