Abstract

The invention concerns the field of shipbuilding. Claimed is a method for manufacturing a hull of a floating craft, during which a shell is applied on installed templates copying the contours of the hull of the floating craft, a reinforcement is applied on the formed surface, thereafter a composite matrix is applied. The surface of the shell can be additionally covered from the inside with a layer of liquid rubber. Thereafter, on the resulting surface is applied a reinforcement and a composite matrix.

Description

    FIELD OF INVENTION
  • The present invention concerns to the field of shipbuilding.
    • BACKGROUND
  • Known is a method of manufacturing the hulls of river and sea carriers from concrete or reinforced concrete [RU 2483965 C1, 10.06.2013]. It presumes a preliminary selection of the type and provision of a floating craft, the hull design of which meets the requirements for concrete formwork, Said floating craft is placed in a displacement condition. Provided is the supply, distribution and compaction of the concrete mixture in cavities formed by structural elements of the hull of the mentioned floating craft, and the formation of a concrete or reinforced concrete hull of the floating craft. Thus, in fact, concrete is poured into the formwork.
  • Known is a method of manufacturing a reinforced concrete floating block, comprising the operations of building this structure in a dock and of outputting the block to a water area on floating containers [RU 2135384 C1, 27.08.1999]. The budding operations include forming two reinforced concrete block structures in horizontal formwork forms. The forms are symmetrically located relative to the diametrical plane of the dock and are supported by means of hinges on upper edges of parallelepipedal supports facing each other, located on the bottom of the dock. Transfer of formwork forms together with the formed block structures to a vertical position. Connection of reinforced concrete block structures with ties. Removal of formwork forms along the guides to the walls of the dock chamber. Filling the dock with water and fixing floating containers to the wads of the block.
  • The disadvantages of the methods are labor intensities, due to the fact that it is necessary to manufacture the formwork. It is impossible to manufacture the shell thin and light. The production period is very long—the concrete in the formwork hardens within 30 days. It is impossible, to sheathe the concrete externally. In addition, for manufacturing according to the first method a wet dock is required.
  • The closest technical solution is a method of building ships [U.S. Pat. No. 3,668,051. A, 06.06.1972] using fiberglass or ferrocement technologies using a base material that defines the surface from a flexible sheet material, for example, from freely woven fabric or elastic mesh reinforced with springy rods, for example, from fiberglass or steel; the base material is attached to the skeleton frame and simple and easily adopts and forms the complex curved surface of the hull, and then resin or concrete is added and is allowed to harden.
  • Disadvantages: it is impossible to manufacture the outer shed of wood or composite, labor intensities of manufacturing due to the fact that large vessels are difficult to turn around after manufacturing, the fastening of a plank does not imply its fight fit and tightness.
  • A shell is not presumed for this solution. Only painting with either resins or paints.
    • SUMMARY
  • The technical result is the reduction of complexities during manufacturing the hull of a floating craft.
  • The technical result is achieved by using a method for manufacturing a hull of a floating craft, during which a shell is applied on installed templates copying the contours of the hull of the floating craft, reinforcement is applied on the resulting surface, a composite matrix is applied thereafter.
  • For the insulating and damping function, it is possible to manufacture a hull of a floating craft, during which a shell is applied on the installed templates copying the contours of the hull of a floating craft, the resulting surface is covered from the inside with a layer of liquid rubber, reinforcement is applied on the resulting surface, then a composite matrix is applied.
  • Shell in the form of a plank provides for an additional protection against impact effects on the structure. Concrete as such is a brittle material. In addition, the use of a shell leads to an increase in buoyancy, creates an attractive appearance.
  • The method of manufacturing the hull of a floating craft is the opposite to traditionally existing one. A framing is installed inside the already formed shell (frame spacing) of the ship.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • The method is carried out as follows (FIG. 1). On the installed templates, copying the contours of the hull of the ship, a shell 1 (for example planks) is applied, which acts as a fixed formwork. As boards is used any suitable material that meets basic requirements: non-rotting, smooth (having a surface with minimal resistance to gliding through water), decoratively attractive. In addition to boards, lamellar shell or decorated with plates.
  • The resulting surface is optionally covered from the inside with a layer of liquid rubber 2 with a thickness of 1-3 mm. Rubber plays an insulating and damping function between the main bearing body made of composite matrix 3 and the shell 1.
  • In the shell of the ship are inserted treenails 5 (FIGS. 1, 2) at the locations of the intended installation of future frames 6 (FIG. 1). The treenails tighten the composite matrix and the decorative shell.
  • On the formed surface is applied a reinforcement 4, for which can be used for example fiberglass reinforcement with a pitch of 50-150 mm (depending on the size of the floating craft) along the hull of the ship.
  • Composite matrix 3 (FIG. 2) is applied using the pneumatic spray method with a thickness of 10-30 mm (the thickness corresponds to the size of the floating craft). As composites can act, for example, fiber-reinforced concrete or polymer resins with a fiberglass filler.
  • In the targeted planes is installed the formwork and concrete frames are formed, Depending on the size and purpose of the ship, the frames can be combined with holder partitions.
  • Using the method allows quickly and without unnecessary labor costs to manufacture, a floating craft. Including field conditions, without the construction of bearing structures. It is sufficient to deliver or manufacture templates on the spot. Deliver or manufacture the shell on the spot. Placing it on the templates. And in the future, without significant labor costs, to manufacture a floating craft.
  • All of the above mentioned advantages significantly reduce the costs and duration of manufacturing the product, which is very important for mass production in tourist entertainment industry.
