RU196584U1 - Floating lightweight square block slab - Google Patents

Abstract

The main direction of the proposed utility model is the creation of a lightweight construction with minimal labor and materials. The supporting elements are square blocks assembled from pieces of galvanized steel profiled sheet through corner connecting elements with self-tapping screws, through fiberglass spacers impregnated with epoxy resin. Square blocks are laid on the base from asbestos-cement plates and are joined together by self-tapping screws with the installation of gaskets made of fiberglass, impregnated poksidnoy resin. The volume of square blocks is filled with polystyrene concrete with a volume weight of 150 kg / m3. The top coating of asbestos-cement boards is fixed with self-tapping screws in the corner connecting blocks. The height of the segments of the galvanized profiled sheet is selected depending on the specified loads and the selected dimensions and thickness of the sheet. If necessary, fire resistance of structures serving as overlapping, the bottom asbestos-cement plate is made with a honeycomb frame of 20-40 mm filled with gypsum.

Description

Depending on the purpose of the proposed utility model — moorings and floating platforms, foundations for low-rise buildings on flooded soils, floor floors — and payloads, the height of the sections of the galvanized profiled sheet is determined. The segments are connected into square blocks by means of angular connecting elements made of galvanized steel from the inside.

Square blocks are joined together by gaskets made of fiberglass impregnated with epoxy resin, creating the desired product - plates, three-dimensional blocks of floors and bases as foundations, floating platforms.

The assembly of blocks is carried out on asbestos-cement slabs up to 10 mm thick, which serve as the bottom for floating structures, the base for the foundation slab, and the ceiling for ceilings. After assembling the required product into the design dimensions, square blocks are filled with polystyrene concrete with a volume weight of 150 kg / m3, and the top cover is made of asbestos-cement slabs of the required thickness (up to 20 mm), which serve as the basis for clean floors or as an exploited flooring.

Fastening of asbestos-cement plates is carried out by self-tapping screws to the connecting elements.

Prefabricated monolithic ribbed floors using profile beams and formed voids that reduce its weight.

The difference of the proposed utility model is:

- the use of segments of galvanized profiled sheet as load-bearing elements, providing the required load-bearing capacity (for floors and bases);

- the use of lightweight non-bearing polystyrene concrete, which serves as a heat and waterproofing, which provides buoyancy when installing floating platforms, berths .;

- contact connection of corrugated sheets with fiberglass seals impregnated with epoxy resin, without the use of special connecting elements;

- weight reduction of 19 times with the possibility of using as a base on flooded and frozen soils of the Northern region and the installation of lightweight insulated ceilings during the reconstruction of existing panel 3-5-storey buildings with a superstructure of floors;

- fire resistance of structures when installing asbestos-cement boards filled with gypsum, through fire-resistant honeycombs with a height of 20-40 mm.

The technical result of the proposed utility model:

The device of the supporting structure is made of square blocks of segments of galvanized profiled sheet, interconnected by fiberglass on an epoxy resin filled with lightweight up to 150 kg / m3 polystyrene concrete, which serves as heat and waterproofing, ensuring buoyancy.

The objective of the technical result when using:

The installation of structures on the water surface - moorings, platforms, navigation bridges, outdoor pools, awnings, houses, offices, warehouses, etc.

Installation of foundations for low-rise construction in flooded areas and in permafrost.

The device of interfloor ceilings during the reconstruction of existing reinforced concrete panel 3-5 floors buildings by the method of superstructure floors.

Utility Model Feature.

The proposed utility model is a lightweight design that can be used as:

- floating moorings, platforms;

- grounds for low-rise construction in flooded areas and in permafrost;

- lightweight ceilings during the reconstruction of existing reinforced concrete panel 3-5 storey buildings using the superstructure of floors.

The composition of the structure:

- square blocks of pieces of galvanized profiled sheet connected by connecting corner elements;

- the connection of the blocks together with gaskets made of fiberglass impregnated with epoxy resin;

- lower asbestos-cement sheet, which serves as the basis of the desired product (plate, platform, floor);

- filling a square block with polystyrene concrete with a bulk weight of 150 kg / m3

- the upper asbestos-cement sheet, which serves as a flooring when used as a floating product or as a base for clean floors when used as plates, structural ceilings.

The weight of the proposed design when used as bases and ceilings is 19 times less than analogues.

Utility Model Implementation

Using the proposed utility model can be implemented:

- as a floating berth structure, platform for superstructures - in any body of water in the Russian Federation;

- as a basis for low-rise construction - in flooded areas and in permafrost. On the ice fields of the Arctic;

- as slabs and structural elements - during the reconstruction of reinforced concrete panel 3-5 storey buildings using the superstructure of floors.
