RU183387U1 - PONTOONS OF LARGE LOAD CAPACITY FROM THE PAINTED GALVANIZED PROFILE SHEET - Google Patents

Abstract

The main direction of the proposed utility model is a tool for performing work on the water surface of any water bodies of the Russian Federation. The proposed element of a single pontoon in dimensions that allow its transportation by road, 12 × 2.2 × 2.5 (N) m, provides a payload of 20 tons. a block of two pontoons provides a useful load capacity of 40 tons. The connection of double pontoons into blocks is possible in length and width in various configurations due to flexible inserts. The design of a single pontoon consists of the following elements: - frame made of light galvanized steel profiles; - outer cladding from a bearing painted galvanized profiled sheet; - inner lining from a non-bearing painted galvanized profiled sheet; - filling the space between the sheets with polystyrene concrete with a volume of up to 200 kg / m. - internal diaphragms every 3 m from painted galvanized profiled sheets .Longitudinal joints of profiled sheets are performed using fiberglass gaskets on epoxy resin. End joints are sealed with fiberglass with epoxy th resin and protection of painted galvanized bent stali.Vse connections are self-tapping screws with sealing prokladkami.Soedinenie single pontoons on the upper belt is performed in units of trusses galvanized light steel profiles and horizontal connections along the lower zone of the lung single galvanized steel profiles.

Description

The frame structure is made of light steel profiles, lined on the outside and inside with painted galvanized profiled sheets with sealing joints of epoxy resin gaskets and the space between the profiled sheets is filled with polystyrene concrete.

Prior art;

An analogue of the proposed utility model is steel and concrete pontoons, made according to shipbuilding technologies, having large dimensions and large dead weight due to the presence of frames, diaphragms and fastening elements.

The difference of the proposed utility model is:

- manufacture of a supporting frame from galvanized light steel structures;

- the outer lining of the bearing painted galvanized profiled sheet;

- inner lining of non-bearing painted galvanized profiled sheet;

- sealing of longitudinal joints with gaskets with epoxy resin;

- the absence of transverse joints in the lining;

- connection of all parts with self-tapping screws with sealing elements;

- the presence of only end joints, decorated with overlays made of fiberglass with epoxy resin;

- low dead weight of the finished product and, accordingly, a large carrying capacity;

- anti-corrosion through the use of hot-dip galvanized elements.

The technical result of the proposed utility model:

- increase in carrying capacity in comparison with analogues;

- durability due to the anticorrosive properties of the materials used;

- lack of welded joints;

- tightness of lining and moisture resistance filling the space between them;

- the ability to assemble the product in any site or room in the absence of welding;

- reducing the cost of the finished product through the use of economical materials, assembly technology and low dead weight.

The objective of the technical result when using:

- cost reduction when performing work on the water surface of any water bodies;

- the ability to assemble products outside special shipyards;

- the possibility of using products in aggressive sea waters.

Utility Model Feature.

In the given dimensions of the product, not exceeding a length of 12 m, in order to use a standard profiled sheet and the absence of transverse joints, a supporting frame is assembled from galvanized standard steel profiles on self-tapping screws.

The external load-bearing circuit is lined with painted galvanized profiled sheets with characteristics that ensure water pressure.

The inner non-bearing contour is faced with non-bearing painted galvanized profiled sheets.

The space between the cladding sheets is filled with polystyrene concrete with a volume weight of up to 200 kg / m3, which provides moisture resistance.

The butt joints of the cladding are sealed with fiberglass on epoxy resin and protected by bent elements of painted galvanized steel.

The longitudinal joints of the cladding are performed using flexible fiberglass gaskets on epoxy resin.

A 12-meter-long pontoon section is separated by sealed diaphragms from a painted profiled sheet every 3 m.

Single pontoons are connected into blocks using load-bearing trusses made of galvanized light steel profiles, on which a load-bearing floor made of expanded metal is laid.

The lower level of the pontoons is unfastened by horizontal ties of galvanized light steel profiles.

Implementation of a utility model:

The use of the proposed utility model can be carried out when performing work on the water surface of any water bodies of the Russian Federation.

Blueprints:
