PURPOSE: To provide a roof structure for an agricultural greenhouse, good in executability in the field, having high heat insulating effects and capable of preventing dews from condensing on the inner surface of the agricultural greenhouse, protecting crops and promoting the growth by irradiating the crops with the sunlight. CONSTITUTION: This roof structure for an agricultural greenhouse is obtained by installing moors 7 formed of a metallic material on a roof of the agricultural greenhouse having a frame, made of the metallic material and assembled in the form of a house, attaching each fixing metallic fitting 8 comprising a part 11 of U-shaped cross section, a vertical plate part 14 integrally formed in the lower part of an opening 12 thereof and a moor engaging part 15 integrally formed in the lower part of the vertical plate part 14 to the upper part of each moor 7, fitting the upper-stage side of a panel-like hollow platy roofing material 9 stretched with a light transmitting outer wall film 19a and a light transmitting inner wall film 19b on both the top and the bottom surfaces of a square metallic frame into each part 11 of the U-shaped cross section, fitting the lower-stage side of the hollow platy roofing material 9 into a space between the base 13 of each part 11 of the U-shaped cross section and the upper surface 7c of the moor 7 and forming the roof 10. |
