A combined cargo container is known, comprising a body and a removable box-shaped lid, one of the end walls of which is made in the form of hinged doors, the body contains a rectangular frame made in the form of a beam framework containing longitudinal and transverse beams, side and end walls, a support in the form of a pair of inclined flat plates connected by reinforcing elements to the beams of the frame, characterized in that on the inner surface of the side walls of the body, on their upper sections, support beams are fixed, located horizontally, said support beams are intended for placing a floor slab on them above the support, made with a width that ensures its removal through the doorway, brackets are fixed on the upper sections of the side walls of the box-shaped lid, intended for placing the floor slab on them, while in the end of the floor slab facing the doorway, openings are made for the forks of a forklift (patent RU 229574, B65D 88/12, published 14.10.2024).

The common disadvantage of known solutions is the high weight and insufficient load-bearing capacity of the container. When using aluminum alloy as a material for walls and beams, the structure will not be reliable enough.

An isothermal container is known, comprising a metal frame with upper and lower corner fittings, a floor and a roof, heat-insulating panels, each of which is formed by outer and inner metal sheets, forming respectively the outer and inner wall cladding, a heat-insulating layer located between the metal sheets, the metal frame is made in the form of a rigid frame structure, the heat-insulated panels are fixed to the frame, the metal sheets of the outer cladding of the side walls are rigidly connected to each other, the metal sheets of the inner cladding of the side walls are rigidly connected to each other, characterized in that the thickness of the outer cladding, made of steel, is 0.6 ÷ 0.9 mm, the thickness of the inner cladding, made of aluminum alloy, is 105 ÷ 130% of the thickness of the outer cladding, the heat-insulating layer between the outer and inner cladding is made of foamed polymer, and the distance between the outer and inner cladding is 50÷70 mm (patent RU 224039, B65D 88/74, B65D 81/38, published 13.03.2024).

The known solution partially solves the problems of previous analogues, namely, the weight is reduced, the container's load capacity is increased, since the design partially uses aluminum alloy instead of steel. The disadvantage of the known solution is the insufficient reliability of the container.

The container according to patent 224039 was chosen as the closest analogue.

The technical problem solved by the proposed utility model is the insufficient reliability of the container.

The technical result achieved by the utility model is an increase in the reliability of the container due to a change in the design of the upper longitudinal beams.

The technical result is achieved due to the fact that in a container containing a metal frame, upper and lower corner fittings, a floor and a roof, side and end walls rigidly connected to the corner vertical posts, the frame is formed by vertical posts, upper longitudinal and transverse beams, lower longitudinal and transverse beams, according to the utility model, the upper longitudinal beams are made of an aluminum alloy with a yield strength of at least 165 MPa, the cross-section of the upper longitudinal beam is made lattice with a width within 40÷90 mm and a length within 70÷130 mm.

The thickness of the walls of the upper longitudinal beam can be 2÷5 mm.

The claimed utility model is illustrated by drawings:

Fig. 1 shows a general view of the claimed container,

Fig. 2 - cross-section of the container,

Fig. 3 - cross-section of the upper longitudinal beam.

Positions on figures:

1 – corner fitting,

2 – floor,

3 – roof,

4 – side wall,

5 – end wall,

6 – corner vertical post,

7 – lower longitudinal beam,

8 – upper longitudinal beam.

The container comprises a metal frame with upper and lower corner fittings 1, a floor 2 and a roof 3, side 4 and end 5 walls rigidly connected to corner vertical posts 6. The frame is formed by corner vertical posts 6, upper longitudinal 8 and cross beams, lower longitudinal 7 and cross beams. The upper longitudinal beams 8 are made of aluminum alloy with a yield strength of at least 165 MPa, the cross-section of the upper longitudinal beam 8 is lattice with a width within 40÷90 mm and a length within 70÷130 mm.

The thickness of the walls of the upper longitudinal beam 8 can be 2÷5 mm.

Compared to the analogue, in which the upper longitudinal beams do not contain internal stiffeners, in the claimed utility model the upper longitudinal beams 8 are made with a transverse lattice section, thus introducing an additional stiffener. Also used is an aluminum alloy with a yield strength of at least 165 MPa, which increases the strength of the upper longitudinal beams 8. The cross-section of the upper longitudinal beam 8 is made lattice with a width within 40 ÷ 90 mm and a length within 70 ÷ 130 mm. Calculations have shown that with a width B below 40 mm and / or a length L less than 70 mm, the strength of the upper longitudinal beams 8 will be insufficient, which will lead to the unreliability of the container. With a width B greater than 90 mm and / or a length L greater than 130 mm, the mass will increase and the load-bearing capacity of the container will decrease, which will make its operation impractical. Taken together, the proposed design of the upper longitudinal beams 8 will improve the reliability of the container.

The thickness S of the walls of the upper longitudinal beams 8 can be 2÷5 mm. Calculations have shown that with a wall thickness S of less than 2 mm, the strength of the upper longitudinal beams 8 can decrease, which will reduce the unreliability of the container. With a wall thickness S of more than 5 mm, the mass will increase and the load-carrying capacity of the container will decrease, which will reduce the efficiency of its operation.

An experimental container was manufactured in which the upper longitudinal beams were made of aluminum alloy with a yield strength of at least 165 MPa, the cross-section of the upper longitudinal beam was made lattice with a width of 60 mm and a length of 100 mm, and the thickness of the walls of the upper longitudinal beam was from 3 to 4 mm. At the same time, tests showed that the container withstood increased loads.

Consequently, the claimed utility model allows for a technical result consisting in increasing the reliability of the container by changing the design of the upper longitudinal beams.
