FALLING WATER PREVENTION DEVICE IN A MULTI-SPAN TYPE GREENHOUSE

摘要

PROBLEM TO BE SOLVED: To provide a falling water prevention device in a multi-span type greenhouse that can reliably prevent water such as dew condensation water from falling into a field etc. below a trough of the multi-span type greenhouse, improve heat retention and maintain a good environment inside the greenhouse.SOLUTION: The falling water prevention device 10 in a multi-span type greenhouse comprises: a plurality of support columns 12 erected to be spaced apart from each other along the longitudinal direction of a trough 102 below the trough 102 formed between the roofs of the multi-span type greenhouse; a convergent sheet member 14 which is extended along the longitudinal direction of the trough 102 and opens upward at both sides below the trough so as to be close to the bottom edge thereof; a plurality of gutter members 16 provided long at the lower end of the convergence sheet member 14 along the longitudinal direction and opening on the upper side and bridging between adjacent support columns 12; and a gutter receiving portion 18 including an engaging portion 24 for receiving and supporting the end portion of the gutter member 16 provided at a predetermined height position from the ground of the support column 12 and having a flow path 26 for communicating between gutter members 16 arranged at the front and rear of the support columns 12 and allowing water to flow therethrough.SELECTED DRAWING: Figure 2
