A greenhouse is a prefabricated greenhouse, containing a frame, having a side surface formed by arcs interconnected from above in pairs, made up of parts, and longitudinal parts, end structures with doors and windows, translucent coating, embedment units, while all frame parts have a paintwork or other protective coating from corrosion and made of cold-rolled sheet steel profile having a middle shelf, inclined side walls and bends to the outside of the edges, arcs form a lancet structure, bends of the profile Execute a lateral flanges； all external parts of the side surface of the frame are turned by the middle flanges of the profile inward, while all the details of the arcs are lapped together and fastened with screw connections, the arcs are connected with the longitudinal parts by screwing together the side shelves of the longitudinal part on the side flange of the arc； in the ridge part of the arc are interconnected by corner plates and covered with an angular ridge profile； the arcs are equipped with braces in the form of chords, while the arches in the area of bonding with the upper parts of the braces are connected in pairs by couplers, and the middle parts of the braces are connected with their arcs by radial couplers, characterized in that the braces and couplers are connected in the region of their joints with the arcs by corner braces made from the same profile； the struts are connected with arcs, radial ties with arches and struts, and corner ties with struts and ties, screw connections on the side shelves of the profiles, for which cuts of the middle shelf and inclined side walls of the profiles are made at the ends of the struts, radial and corner ties,Техническое решение относится к садоводству, к разведению цветов, овощей, ягод и т.п. в парниках и теплицах, а конкретно к конструкции каркасов теплиц. Задачей, на решение которой направлена предлагаемая полезная модель, является повышение прочности и жесткости конструкции каркаса теплицы. Для решения на
