STRUCTURE FOR SIMULTANEOUSLY FASTENING PROTECTIVE NET FOR GREENHOUSE AND PROTECTIVE BELT AND METHOD FOR USING THE SAME

摘要

PPROBLEM TO BE SOLVED: To provide a fastening structure capable of simultaneously, rapidly, simply and strongly fastening a protective net for greenhouse and a large number of protective belts by uniform tension and capable of simply carrying out fastening and unfastening and to provide a method for using the structure. PSOLUTION: Both lower ends of the protective net for greenhouse and both ends of each protective belt are previously attached to a tension pipe 3 horizontally supported on the lower part on both sides of greenhouse and tension is applied to the net and each belt by winding at least each one end side of the net and each belt around the tension pipe 3. Since the structure is constituted so as to rotate the tension pipe by utilizing a manual driving means having same principle as a well-known winder, both of the protective net for greenhouse and each protective belt are simply and rapidly fastened together and it is made possible to keep definite tension and whole surface of a covering material of a vinyl sheet, an insect proof net, etc., can stably, surely and uniformly be pressed to a main frame of greenhouse and it can be prevented that the covering material is swung or broken by strong wind.
