Abstract

FIELD: construction.

SUBSTANCE: invention relates to structures of floating means, applicable for various purposes. Floating island consists of a set of hollow blocks of spherical shape with a hexagonal belt, rigidly interconnected, forming a large area structure of the required shape. Assembled structure of hollow spherical blocks with a hexagonal belt in the upper part and filled with foam is only the basis for the construction of the main structure of monolithic reinforced concrete in the form of tiers in the form of honeycombs. Overlap of each tier is reinforced starting from the first row of spherical blocks, where the fittings are pulled through pre-prepared holes, tightened and poured with concrete, and in all tiers and partitions there are openings for the passage and installation of the necessary equipment.

Description

The present invention relates to the construction of floating equipment intended for various special purposes: for the placement of industrial, industrial, research, health, residential facilities and for the placement of runways and launch sites.

The floating island is a three-dimensional structure, partially immersed in water, and made of a precast base and a body of monolithic reinforced concrete.

Known invention KR 101419188 related to pontoons having floating blocks, consisting of a platform with hollow cameras fixed from below, from which a flat floating structure is assembled.

This design is designed for shallow penetration.

Known invention RU 2483965 "Method for the construction of a floating facility, mainly river or sea vessel." The method consists in the fact that in order to form a floating hull, a box-type waterproof formwork is lowered into the water inside which a concrete hull is formed by pouring from an auxiliary vessel.

This method is convenient for forming one housing and is inconvenient if it is necessary to assemble several buildings together.

Known invention RU 2457144 "Floating island". The floating island contains a platform resting on a floating base immersed in the aquatic environment, which is made of motionlessly interconnected many parts enclosed in a rigid frame of the island. The central array is movably connected to peripheral arrays.

Such a design does not provide for rigid structures of large area or large extent.

The invention is known RU 2545128 "Floating island", which is a partially immersed volumetric structure having underwater and surface parts. This volumetric design is made of a number of floating means, which are interconnected by means of a flexible inextensible connection and an elastic damping connection.

This design allows you to create a large surface area, but does not allow you to create a large rigid surface.

The present invention is aimed at achieving a technical result, which consists in simplifying the process of forming a large-sized floating structure using sections manufactured in the factory, their further assembly on water and the creation of a monolithic structure of reinforced concrete based on them. The aim of this invention is to create a solid monolithic structure capable of withstanding heavy loads of both static and dynamic nature; the ability to create various shapes in plan in the form of a rectangular, round, oval or annular; different in height and depth of immersion.

As a prototype, the invention KR 20150061893 was chosen as the closest structurally, where the pontoon is formed from hexagonal blocks with grooves and holes for their connection.

The technical result is achieved by the fact that the base of a floating island is collected in calm water from hollow blocks with a spherical surface in the lower part and a hexagonal belt in the upper part. The internal volume is filled with polystyrene to the level necessary to keep the block afloat in the event of its capsizing. The side surfaces of the faces have the required number of holes for connecting the blocks together using any of the known methods. The upper surface of the faces has the required number of outlets of reinforcement. After the formation of the field of the required shape and dimensions from the blocks fastened together, a vertical frame is installed to the required height from the reinforcement along all faces in the form of honeycombs with the necessary openings for passing from one cell to another. Then the formwork is installed and everything is filled with concrete. Through the holes in the side faces of the blocks, the required amount of reinforcement is passed and stretched over the entire length of the formed field in all horizontal directions. After dismantling the formwork, the foam is removed from the blocks and everything is filled with concrete, thereby creating a lower monolithic belt. A horizontal formwork with the necessary openings is installed on top of the formed partitions, the reinforcing cage is laid and poured with concrete. Next, the necessary number of tiers of honeycombs or other necessary shape and dimensions of the premises are formed in a similar way.

In FIG. 1 is a side view of the block, where 1 is the hexagonal upper belt of the block, 2 is the lower spherical part of the block, 3 are the holes for fasteners and fittings.

In FIG. 2 shows a top view of the block.

In FIG. Figure 3 shows a fragment of the assembled field of blocks, where 4 is the prestressed reinforcement of the lower zone.

Assembly technology is as follows. In the factory, spherical shells are made of reinforced concrete of the required size with a hexagonal belt in which there are many holes for passing reinforcement and fasteners along each face in the midline. On the top of the hexagonal belt there are rebar releases. The internal volume of the spherical shell is filled with foam in a volume sufficient to keep the finished block afloat if it capsizes during launching or during installation. The required number of ready-made blocks are launched into the water and interconnected, forming a field of the necessary shape and necessary dimensions. Blocks are connected through the prepared holes by any of the known methods. After the field is formed, vertical reinforcing grids are installed along all faces to the required height, in which openings are provided for passage from one cell to another, then the formwork is mounted and everything is filled with concrete. Foam is removed from the spherical shells, reinforcement is pulled through the prepared holes in the hexagonal belts in the required amount in three directions, stretched by any of the known methods, and everything is filled with concrete to the required level. Thus, the lower reinforced belt of the future design is formed. After dismantling the formwork, a horizontal formwork is installed on top of the formed partitions, a reinforcing mesh with the required number of openings is mounted and filled with concrete. After that, on the formed overlap of the first lower row of rooms in the same way, the next row of rooms is formed in the form of honeycombs or another type and size intended for specific purposes. Thus, it is possible to form a floating island of the required shape, size needed to perform the necessary functions.
