Description

Изобретение относитс  к сельскому хоз йству а именно к устройству покрытий дл  теплиц. Известна пленочна  теплица дл  выращивани  сельскохоз йственных культур, покрытие которой состоит из одного сло  пленки, нат нутой на каркас теплицы 11 . Недостатком указанной теплицы  вл етс  попадание наружного воздуха внутрь теплицы при открывании форточек, что отрицательно сказываетс  на вырагциваемых культурах в холодное врем  года. Известна теплица, имеюща  двухслойное пленочное покрытие. Воздушна  прослойка улуч шает теплоизол цию теплицы 2. Данное покрытие теплицы  вл етс  наиболее близким к изобретению по технической сущности . Недостатком его  вл етс  попадание наружного воздуха внутрь теплицы при открывании форточек во врем  вентил ции. Целью изобретени   вл етс  улучи1ение условий вентил 1Ц1И теплицы и предотвращение попадани  внутрь ее наружного воздуха. Указанна  цель достигаетс  тем, что слои пленок имеют перфорашш, выполненную с равным maiOM таким образом, что отверсти  одного сло  пленки смещены относительно отверстий другого сло  на полшага, а сами пленки скреплены между собой в точках, расположенных в промежутках между отверсти ми, причем пленка, наход ща с  снаружи, выполнена из более эластичного материала, чем пленка, обращенна  к внутреннему объему теплицы. На фиг. 1 изображено покрытие дл тешти, вид сверху; на фиг. 2 - сечение .-А на фиг. 1. Цокрытие состоит из двух слоев пленок- 1 и 2, имеющих перфорацию 3 и 4, выполненную с равным щагом. Пленки 1 и 2 соединены межцу собой точечными спа ми 5 так, что отверсти  пленки 1 смещены относительно отверстий пленки 2 на полшага, а места точечных спаев 5 расположены в промежутках между отнерсти ми пленок. Пленка 1 изготавливаетс  из более зластичного материала, чем пленка 2. При установке покрыти  на теплице пленка. 1 должна находитьс  снаружи, а пленка 2 обращена к внутреннему объему теплицы.FIELD OF THE INVENTION The invention relates to agriculture, namely to the arrangement of coatings for greenhouses. The known film greenhouse for growing agricultural crops, the coating of which consists of a single layer of film stretched over the frame of the greenhouse 11. The disadvantage of this greenhouse is the ingress of outside air into the greenhouse when opening the vents, which has a negative effect on the crops being thrown out during the cold season. A greenhouse having a two-layer film coating is known. The air gap improves the thermal insulation of the greenhouse 2. This greenhouse coating is closest to the invention in its technical nature. The disadvantage of it is the ingress of outside air into the greenhouse when opening the vents during ventilation. The aim of the invention is to improve the conditions of the 1C1I valve of the greenhouse and to prevent outside air from getting inside it. This goal is achieved by the fact that the layers of films have a perforation made with equal maiOM in such a way that the openings of one layer of the film are displaced relative to the openings of the other layer by half a step, and the films themselves are fastened together at points located between the openings, and the film located outside, is made of a more elastic material than the film facing the inner volume of the greenhouse. FIG. 1 shows a coating for a test, top view; in fig. 2 is a section. -A in FIG. 1. The coating consists of two layers of films - 1 and 2, with perforations 3 and 4, made with an equal schag. Films 1 and 2 are interconnected by point spans 5 so that the apertures of film 1 are displaced relative to the apertures of film 2 by half a step, and the points of point junctions 5 are located in the intervals between the films. The film 1 is made of a more elastic material than the film 2. When installing the coating on the greenhouse film. 1 must be outside and the film 2 faces the inner volume of the greenhouse.
