GREENHOUSE COVERED WITH GLASS Russian patent published in 2019 - IPC A01G9/14 

FIELD: agriculture.

SUBSTANCE: invention relates to the field of agriculture and may be used for growing crops. Greenhouse contains a metal frame of round tubes with a rectangular base and a roof with two slopes converging at an angle α, covered with a ridge profile, opening doors at the ends of the greenhouse. Frame stands are interconnected and with side and ridge purlins with metal plates with a central hole D and with two or three ribs, two of which intersect at an angle α and go inside the racks. Ends of the racks are machined along the outer diameter of the girders and have diametrically opposite slits along the axis of the racks with a width equal to the plate thickness h. Ridge and side runs pass through the central holes of the plates along the entire length of the greenhouse and at the same time can be used to water the plants and create a microclimate inside the greenhouse. Vertical posts are connected to the base of the frame with clamps welded to the posts and bolted together. Angular connections of the base, side girders with crossbars and with racks, ridge girder with ridge racks are carried out in corners, and the connection of racks with crossbars is carried out by plates and bolted together. From the outside of the frame ⊥-shaped wooden slats are fixed, on the underside of which there are slots for protruding metal plates. Glass is installed on wooden planks and fastened on both sides with a bead and small nails, the corners are fixed to the ends of the planks with screws. Ridge profile is mounted on top of the greenhouse. To reduce the bending of the girders, tie bars are used that are connected to side girders by clamps and bolted together. Such a design of the metal frame ensures the simplicity of the greenhouse, a more rational use of the internal space and allows for the replacement of glass. Greenhouse does not require a capital foundation.

EFFECT: covering a greenhouse with glass provides ease of maintenance, retains transparency for many years, a gable roof prevents the accumulation of snow and condensate.
