Description

Известно устройство креплени  поперечных краев пленочного покрыти  теплнцы, содержащее парные элементы в виде двух шпросов, между кот рыми зажат край пленки. Однако в таком устройстве зажагне пленки между шпросами преп тствует свободному перемещению ее краев, что ведет к быстрому износу пленки. Цель изобретени  - уменьшение износа пленк Это достигаетс  тем, что парные элементы вы полнены в виде свободно вращающихс  роликов а край пленки навернут на шинку. На фиг. 1 изображена теплииз, вид в плане; на фиг. 2 - то же, вид сверху; на фиг. 3 - сечение А-А фиг. 1; на фиг. 4 - схема креплени  пле ки на нат жном валике (узел Т на фиг. ,); На трубчатом шпросе 1 в поперечном направлении теш1ищ 1 на .основани х 2 установлены ролики 3 и 4, между которыми расположена металлическа  пшика 5 пр моугольного сечени , По краю кровли вдоль оси теплицы установлен нат жной валик 6, закрепленный на разжелобчатых стойках 7 каркаса теплицы в подшипниках 8 скольжени . Теплица покрыта пленкой 9. наворачиваетс  на пшнку 5, котора  при сн том с основани  2 ролике 3 заводитс  в прострганство между роликами и закрепл етс  в этом положении установкой ролика 3 на свое место. Такое закрепление полотна прюизводитс  с обеих поперечньк сторон кровли теплицы. Два других кра  полотна покрыти  наворачиваютс  на нат жные валики. Поворотом валиков посредством рычагов полотно покрыти  нат гиваетс . Благодар  тому, что ролики не преп тствуют свободному скольжению в некоторых пределах шинки с пленкой, между ними происходит равномерное нат жение пленки в продольном и поперечном направлени х. При получении требуемой степени нат жени  покрыти  кровли положение нат жных валиков фиксируетс . Благодар  такому креплению поперечных краев пленки покрыти  теплицы увеличиваетс  срок ее служ5ы ,а также снижаетс  трудоемкость замены пленкиФормула изобретени  Устройство креплени  поперечных краев пленки покрыти  теплицы, содержащее парные элементы. между которыми зажат край плешей, отличающеес  тем,что,с целью уменьшени  износа пленки, парные элементы вьшопнены в виде свободно вращаюA device for fastening the transverse edges of a film coating of warming is known, which comprises paired elements in the form of two wires, between which the edge of the film is clamped. However, in such a device, the ignition of the film between the interferences prevents the free movement of its edges, which leads to a rapid deterioration of the film. The purpose of the invention is to reduce the wear of films. This is achieved by the fact that the paired elements are made in the form of freely rotating rollers and the edge of the film is screwed onto the splinter. FIG. 1 shows a thermal view in plan view; in fig. 2 - the same, top view; in fig. 3 - section A-A of FIG. one; in fig. 4 is a schematic of fastening the strap on a tension roller (node T in FIG.,); Rollers 3 and 4 are mounted on the tubular sprese 1 in the transverse direction of the cakes 1 on the bases 2 and between them there is a metal bar of 5 rectangular cross section. 8 sliding bearings. The greenhouse is covered with a film 9. It is screwed onto a pnc 5, which, when it is removed from the base 2 of the roller 3, is inserted into the space between the rollers and fixed in this position by mounting the roller 3 into place. This fastening of the web is produced on both transverse sides of the roof of the greenhouse. The other two edges of the cover web are screwed onto the tension rollers. By turning the rollers by means of the levers, the coating web is tensioned. Due to the fact that the rollers do not prevent free sliding in some limits of the shank with the film, between them there is a uniform tension of the film in the longitudinal and transverse directions. When the required degree of tension of the roof covering is obtained, the position of the tension rollers is fixed. Due to such fastening of the transverse edges of the greenhouse coating film, its service life is increased, and the laboriousness of film replacement is reduced. Formula of the invention The fastening device of the transverse edges of the greenhouse coating film containing paired elements. between which the edge of the implant is clamped, characterized in that, in order to reduce the wear of the film, the paired elements are folded in the form of freely rotating
