Method for manufacturing a glass fiber reinforced plastic boat by means of a staggered joint

Abstract

A method for manufacturing a fiberglass boat using staggered assembly involves first creating a staggered grid pattern on the outer surface of a model boat using steel sheets or plastic plates. Next, within each grid area, a template is made using plaster or plastic to create a mold of the surface shape of each area. Then, fiberglass or carbon fiber composite materials are used to manufacture the various hull modules within each mold. Finally, these modules are assembled into the boat hull. The advantages of this invention are its ability to accurately replicate the complex curved surfaces of a model boat, ease of assembly and disassembly of the resulting hull, convenient long-distance delivery and sales, low production costs, and suitability for large-scale, intensive manufacturing.

Description

Technical Field

[0001] This invention relates to a method for manufacturing fiberglass boats with staggered assembly, particularly a brick-like staggered assembly modular component, which allows each modular component to share the stress on the hull. Background Technology

[0002] Existing technologies require relatively large vessels that meet safety standards, making them unsuitable for transport on ordinary roads and unable to be deployed over long distances. Chinese patent CN101445150A discloses a "plastic assembly boat" assembled from plastic sheets and interlocking fasteners, with the fasteners bearing the load. This type of boat has weak bending resistance in turbulent waters and can only be made into small, micro-sized vessels. Chinese patent CN111038644A discloses a "steel-plastic assembly boat," characterized by buoyancy blocks filled within a mesh-like steel frame. This type of boat has a simple shape and cannot be manufactured into high-speed vessels with complex curved surfaces. Summary of the Invention

[0003] In order to overcome the problems existing in the prior art, the present invention provides a method for replicating a model ship into a new ship hull. The method of the present invention is characterized by complete assembly of parts, which facilitates long-distance transportation and delivery and is conducive to large-scale and intensive production and manufacturing.

[0004] This invention is a method for manufacturing fiberglass boats using staggered assembly. The invention first creates a staggered grid pattern on the outer surface of the model boat using steel sheets or plastic plates.

[0005] The present invention uses plaster or plastic to etch the surface shape of each grid block and an outer fold template with edges.

[0006] The present invention attaches a shim half the thickness of the grid plate to the outer edge of the template to fill the space of half the thickness of the grid plate, and then screws on a steel sheet or plastic plate of appropriate width to the edge to make a mold.

[0007] In the above-mentioned manufacturing template, the present invention uses fiberglass or carbon fiber composite materials to manufacture modular components with inwardly folded edges. In order to improve the load-bearing capacity of the hull, a wooden or steel frame can be placed as the hull ribs during the manufacturing process of each modular component.

[0008] Finally, the modular components prepared above are aligned at the inner fold edges of adjacent parts, locked with screws, and finally assembled into a new hull. Attached Figure Description

[0012] The manufacturing method included in this invention is to first create a grid pattern on the outer surface of the model ship 1 using a steel sheet or plastic plate as a grid. Then, plaster or plastic is used to take the shape of the surface of each grid block as an outer fold template 3. The template is used to make a mold 4. Then, fiberglass or carbon fiber composite material is used to manufacture the inner fold module components 5 of the hull in the mold 4. Finally, the inner fold module components 5 are assembled into the hull 6.
