1. A greenhouse comprising a single-wall frame made of a profile element, which is made in cross section to its longitudinal axis in the form of an isosceles trapezoid without a lower base, and a segment is made from the lowest point of each side of the trapezoid from the trapezoid itself, thus that two segments are parallel to the upper base of the trapezoid, and the frame contains at least two equal arcs connected in series with each other by at least two longitudinal elements, while in the first order arc, a doorway is fixed, made in the form of two vertical structural elements of the stiffness of the doorway, mounted on the upper part of the first arc, in addition, each vertical structural stiffness of the doorway is connected to the first arc by two horizontal profile elements, with vertical structural elements of the rigidity of the doorway are connected by three horizontal profile elements of the doorway, characterized in that each vertical The inactive stiffening element of the doorway in the form of a profile element contains an overlay on top of it, which is made in cross section to its longitudinal axis of the L-shaped form, each side of the l-shaped plate is parallel to the side of the trapezoid of the profile element, and the plate is installed so that its body completely covers the convexity of the trapezoid of the profile element, while each pad of the vertical structural element of the stiffness of the doorway through the pad of the amplifier of the doorway is connectedГруппа полезных моделей относится к теплицам. Технический результат заключается в повышении надежности конструкции теплицы. Результат достигается за счет теплицы включающей покрытый одной стенкой каркас из профиля, сам каркас содержит по меньшей мере две равные дуги последовательно соединенные между собой по меньшей мере двумя продольными элементами, при этом в первой по порядку дуге закреплен дверной проем выполненный в виде двух вертикальных конструктивных элементов жесткости дверног
