The essence of the utility model.

The profile for the manufacture of the greenhouse is made by bending on special equipment from a special tape or sheet. The profile contains a rack 1 (Fig.1, 2), the lower part of which is bent to both sides with the formation of the lower shelf 2 (Fig.1, 2) of double thickness, with symmetrically located sides. The upper part of the rack 1 (Fig. 1, 2) is bent to both sides with the formation of the upper shelf 3 (Fig. 1, 2) of double thickness, with symmetrically located sides. Rack 1 (figure 1, 2) is made of double thickness and has two, interconnected equal in height of the limb, with the formation of a longitudinal protrusion in the middle of the rack 1 (figure 1, 2). Bending 4 (Figs. 1-4) is made by side 5 (Figs. 1-4) of a steel strip or sheet coming from the upper shelf 3 (Figs. 1, 2) and is directed parallel to the rack 1 (Figs. 1, 2) upwards with the formation directed to the top of the longitudinal channel 6 (figure 4), made between its sides. Bending 7 (Figs. 1-3, 5) is made by side 8 (Figs. 1-3, 5) of a steel tape or sheet coming from the lower shelf 2 (Figs. 1, 2) and is directed parallel to the rack 1 (Fig. 1, 2) downward, with the formation of a downwardly directed longitudinal channel 9 (Fig. 5) made between its sides. The downward side 8 (Figs. 1-3, 5) of the steel strip or bend sheet 7 (Figs. 1-3, 5) directed downward is installed in the upper longitudinal channel 6 (Fig. 4) of the bend 4 (Fig. 1) -4) directed upward, fitting snugly against it. The upper side 5 (Figs. 1-4) of the steel strip or bend sheet 4 directed upward (Figs. 1-4) is installed in the downward longitudinal channel 9 (Fig. 5) of the bend 8 (Figs. 1-3, 5) directed downward, fitting tightly to it, with the formation of a closed connection such as a lock made in the form of a “Laying Seam”. Along the longitudinal protrusion evenly along the outer surface of the limb 8 (Fig.1-3, 5) are made by pressure of the upper layer on the lower conical recesses 10 (Fig.3). In this case, each layer of the longitudinal protrusion made of the sides of the bend 4 (Figs. 1-4) and the bend 7 (Figs. 1-3, 5) are pressed by conical recesses 10 (Fig. 3) to form a type of gear connection between the sides, which provide fixation of the interlocking sides of the limb 4 (Figs. 1-4) and 7 (Figs. 1-3, 5) of the lock and increase the reliability of the closed connection and the durability of the profile structure.

Improving the reliability of the connection when obtaining a bent profile of a closed cross section for the manufacture of a greenhouse and increasing the rigidity and durability of the structure of the profile and its connection is achieved by the fact that the profile has a closed connection such as a lock made in the form of a “Laying Seam”.

All profile elements are made of double thickness with sides symmetrically positioned relative to the rack, which provides an increase in the rigidity of the profile structure. The symmetrical arrangement relative to the rack of the sides of the lower shelf 2 (1, 2) and the upper shelf 1, 2) allows you to evenly distribute the load across the entire profile, which increases the durability of the profile design.

Such a profile allows you to get an element that, in addition to the required strength parameters, allows you to expand the range of its use in the design of the greenhouse in various combinations and combinations.

Example of execution: the rack has a height of 30 mm, the width of the lower shelf is 25 mm, the width of the upper shelf is 25 mm, the height of the longitudinal protrusion is 5.2 mm, the thickness of the workpiece is 0.4-0.5 mm, the height of the conical recesses is half the thickness of the steel strip or sheet, i.e. 0.2-0.3 mm. The internal radii are 0.5 mm, the crescent shape along the length of 1 m, not more than 1 mm, and the maximum deviation of the angles is ± 1 degree.
