Definitions

• a known method of manufacturing the hulls of river and sea vessels from concrete or reinforced concrete [RU 2483965 C1, 10.06.2013]. It provides for the pre-selection of the type and the provision of a floating craft, the hull structure of which meets the requirements for concrete formwork.
• the mentioned floating device is located in a displacement position. Provide the supply, distribution and compaction of the concrete mixture in the cavities formed by the structural elements of the body of the said floating vehicle, and the formation of a concrete or reinforced concrete body of the floating vehicle. Thus, in essence, the concrete is poured into the formwork.
• a known method of manufacturing a reinforced concrete floating block containing the operations of building this structure in the dock and the output of the block to the water area on floating tanks [RU 2135384 C1 27.08.1999].
• Construction operations include the forming of two reinforced concrete block structures in horizontal formwork forms. The shapes are symmetrically located relative to the dock diametral plane and are supported by hinges on the upper facing edges of parallelepiped supports 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 structures of the block with ties. Removal of formwork forms along guides to the walls of the dock chamber. Filling the dock with water and fixing floating tanks on the walls of the block.
• the disadvantages of the methods are in labor intensity, due to the fact that it is necessary to manufacture the formwork. It is impossible to make the skin thin and light. The production time is very long - the concrete in the formwork hardens within 30 days. It is not possible to sheathe concrete externally. In addition, the first method requires a wet dock.
• the closest technical solution is a method of building ships [US3668051 A 06.06.1972] using fiberglass or ferrocement technologies using a base material that defines the surface of a flexible sheet material, for example, from a loosely woven fabric or an elastic mesh reinforced with spring rods, for example, fiberglass or steel; the base material is attached to the frame and easily and easily accepts and forms a complex curved surface of the body, and then resin or concrete is added and allowed to harden.
• a base material that defines the surface of a flexible sheet material, for example, from a loosely woven fabric or an elastic mesh reinforced with spring rods, for example, fiberglass or steel; the base material is attached to the frame and easily and easily accepts and forms a complex curved surface of the body, and then resin or concrete is added and allowed to harden.
• it is impossible to make the external cladding of wood or composite the laboriousness of manufacturing due to the fact that large vessels are difficult to turn over after manufacturing, the board fastening does not imply its tight abutment and tightness
• the technical result is achieved by using a method for manufacturing the hull of the floating vehicle, during which the skin is laid on the installed templates that copy the contours of the hull of the floating vehicle, the reinforcement is laid on the formed surface, then a composite matrix is applied.
• a method of manufacturing the hull of a floating vehicle is possible, during which a skin is laid on the installed templates that copy the contours of the hull of the floating vehicle, the resulting surface is covered from the inside with a layer of liquid rubber, reinforcement is laid on the formed surface, then a composite matrix is applied.
• plank sheathing provides additional protection against impact to the structure. Concrete itself is a brittle material.
• the use of the skin leads to an increase in buoyancy, creates an attractive appearance.
• the method of manufacturing the hull of the floating craft is the opposite of the traditional one.
• the ship kit is installed inside the already formed skin (spacing) of the ship.
• Figure 1 shows the hull of a floating craft made according to the method.
• Figure 2 shows the hull of a floating craft made according to the method.
• Figure 3 shows a process for manufacturing a hull of a floating craft according to the method.
• sheathing 1 for example, boards
• sheathing 1 for example, boards
• any suitable material is used that meets the basic requirements: non-rotting, smooth (having a surface with minimal slip resistance on water), decoratively attractive.
• flake sheathing or other type-setting can be used.
• 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 structural body made of composite matrix 3 and the skin 1.
• Pins 5 (Figs 1, 2) are inserted into the ship's skin in the places of the proposed installation of future frames 6 (Fig. 1).
• the dowels hold the composite matrix and decorative cladding together.
• reinforcement 4 is laid, which can be used, for example, fiberglass reinforcement with a pitch of 50-150 mm (depending on the size of the floating vehicle) along the ship's hull.
• Composite matrix 3 (Fig. 2) is applied by pneumatic spraying with a thickness of 10-30 mm (the thickness corresponds to the dimensions of the floating vehicle).
• the composite can be, for example, fiber-reinforced concrete or polymer resins with fiberglass filler.
• Formwork is installed in the planned planes and concrete frames are formed. Depending on the size and purpose of the ship, the frames can be combined with the hold bulkheads.
• the use of the method allows you to quickly and without unnecessary labor to make a floating vehicle. Including in the field, without the construction of capital structures. It is enough to bring or make templates on site. Lead or fabricate the sheathing on site. Place it on templates. And in the future, without significant labor costs, make a floating vehicle.
