RU193598U1 - Arrangement of steel vertical tanks with a capacity of 100-1000 m3 with walls made of galvanized profiled sheets joined at the joints by self-tapping screws with a fiberglass gasket impregnated with epoxy resin with a sheet assembly on a construction site - Google Patents

Abstract

The utility model relates to construction and can be used in the construction of steel vertical tanks. The technical result of the claimed utility model is to reduce weight, simplify the method of manufacture and installation. The specified technical result is achieved in that the steel vertical tank consists of a bottom, walls, and the walls are made of galvanized profiled sheets, all the butt joints of the walls and the bottom are made with self-tapping screws with strip strip made of fiberglass impregnated with epoxy resin, while the wall sheets are connected to relying on the circular circles of steel I-beams connected to the height of the uprights, forming a supporting frame, the walls are connected to the bottom, which is made of smooth galvanized sheets laid on asbestos-cement slabs, roofing made of smooth galvanized sheets, through the crate resting on girders of galvanized steel channels with double-folded sheets. 3 of FIG.

Description

The proposed device of steel vertical tanks is made of galvanized profiled sheet, with the walls resting on circles from steel I-beams, a flat galvanized sheet resting on the base of asbestos-cement sheets and a roofing made of galvanized profiled sheet laid on girders resting on the outer upper ring circles.

All butt joints are made on self-tapping screws with a gasket in the joints of the sealing and connecting strip of fiberglass impregnated with epoxy resin.

The assembly of the bottom, made of smooth galvanized sheets, is performed on asbestos-cement sheets laid on the design bearing base - asphalt, reinforced concrete.

Joints of sheets are performed with laying strips of 200 mm wide, laid on an asbestos cement slab.

The walls are assembled on a circle made of an I-beam, connected in height by uprights, creating a mounting frame supporting the mounted sheets. Roofing of flat galvanized sheets is carried out according to the runs of galvanized steel channels with the device of double seam joints. The tightness and reliability of the mating of the walls and the bottom is ensured by an annular lining of fiberglass impregnated with epoxy resin.

The prior art:

The manufactured steel vertical cylindrical tanks with a capacity of 100-1000 m ^{3 are} supplied by manufacturers for assembly in two versions:

- Rolled sections for sheet assembly;

- rolls from stacked segments for transportation and deployment at the facility.

All welded joints are subject to inspection, and the assembled tank is subject to hydraulic testing. Patents 1465520 A1, 1830406 A1, 916727, 903544, considered as an analogue for various configurations and differences of individual elements, are based on steel walls and bottoms produced by the above-mentioned methods - rolled sheets or rolls of rolled sheets.

The difference of the proposed design of the utility model is:

- lack of welded joints in the walls, bottom and roof;

- weight reduction of the finished product by more than 3 times;

- the use of circular circles to support wall sheets;

- lack of need for the use of truck cranes and special truck platforms for transportation and installation of rolls.

The technical result of the proposed utility model:

The device of steel vertical tanks with a capacity of 100-1000 m ³ with a lower weight compared to steel counterparts and a simplified method of manufacturing and installation without rolling and critical welding.

The objective of the technical result when using:

Production and installation of light steel vertical tanks without the use of special equipment for rolling and welding and without the use of special vehicles and truck cranes.

Utility Model Feature.

The proposed utility model, which differs from analogues in the method of manufacture and installation, has more than three times less weight and does not require external corrosion protection, consists of the following elements:

- bottoms made of smooth galvanized steel, laid through gaskets on asbestos cement slabs, supported by a design basis (asphalt, reinforced concrete);

- supporting circles from a welded annular I-beam;

- walls of galvanized profiled sheet (thickness and size of the corrugation are determined by calculation);

- a roof made of smooth galvanized sheet, resting on the girders through the crate, with the connection of sheets with double folds;

- all the butt joints of the walls and the bottom are made on self-tapping screws with laying strips of fiberglass impregnated with epoxy resin;

- external elements - stairs, platforms, fences made of galvanized steel profiles, fixed to a supporting frame made of circles;

- if necessary, the thermal insulation device, hooks made of galvanized strips are fastened with epoxy.

Utility Model Implementation

The use of the proposed utility model can be carried out in any region of the Russian Federation without the use of special vehicles and heavy truck cranes.
