The present invention relates to a reinforced prefabricated plastic boat and a drying method thereof, and more particularly, to connect a plurality of plastic (including FRP) plates (boards) to form a hull to reinforce and couple a plurality of reinforcing materials and connecting members. The present invention relates to a reinforced prefabricated plastic boat that maintains structural strength necessary for warping and impact of the hull and a drying method thereof.

In general, small vessels are classified into hull materials, which are usually made of fiberglass reinforced plastics (FRP), which are mainly made of wood and resin, or expensive yachts or boats made of aluminum. Wooden wire is easy to dry, maintain and repair, but has weakness in strength and vibration and short lifespan. Aluminum wire has the advantages of beautiful appearance and light weight. And there is a disadvantage that takes a lot of maintenance. In addition, although there are steel wires, steel wires have sufficient strength but have a disadvantage that they are heavier than other ships and are not easy to maintain and repair. Therefore, in recent years, small ships such as motor boats and coastal fishing boats, which are used for high-speed, easy-to-work, light-weight and corrosion-resistant boats, water skis, etc., have been built using FRP as a main material.

In addition, the FRP ship manufactures a mold for manufacturing the entire linear line such as bow, stern, ship side, and bottom, at once, selects a color on the inner surface of the mold, first performs a coating process on the mold, and finishes painting the mold surface. The outer shape of the hull was formed by laminating glass fibers on a polymer material such as polyester. This technique requires a lot of time and economic investment to build the mold itself, and it is difficult to partially design deformation, which puts a greater burden on the production cost if it is not mass production. There have been a number of problems such as poor stability and reliability of the bond by allowing it to be bonded using an adhesive.

Therefore, as a conventional technique for drying aluminum wire and plastic (including FRP) wire as a prefabricated, there is a 'water leisure prefab boat' published in Korea Utility Model Publication No. 20-194959 (2000.06.26), the present applicant There is a 'drying method of the FRP ship to be dried without a mold and the hull of the FRP ship' of the Republic of Korea Patent Publication No. 2002-88112 (2002.11.27) filed before the improvement, but the registered Utility Model Publication No. 20-194959 As shown in Figs. 1 and 2, the arc is a conventional technique for prefabricating aluminum wires. The aluminum plates are simply assembled by simply fitting the plates with fixing bars and brackets without bolts or riveting. As a constitution, the upper bracket 10 'is unbalanced and has a high possibility of detachment, and the bracket 20' of the bilge portion also has no reinforcing ribs, so there is a problem in strength, and the bottom plate 66 'is divided into left and right sides. In addition, there is not only a big problem in side strength, but also in the overall assembly method, there is no structural member that can maintain structural strength such as transverse ribs, reinforcement plates, reinforcements and external keel. In addition, the applicant's Korean Laid-open Patent Publication No. 2002-88112 of the present applicant is also weak to maintain the lateral strength, the longitudinal strength does not have structural members such as longitudinal stiffeners, longitudinal ribs and keel to maintain the strength of the hull warp and impact There was a problem.

In order to solve the problems of the prior art as described above,

It is an object of the present invention to provide a plastic boat (including FRP) that is prefabricated and dry, unlike conventional plastic (FRP) boats, which are weak in structural strength to prefabricate plastic plates prepared in advance without hull molding mold.
