Embodiment Construction

[0053] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0054] Such as Figure 1-Figure 11 Shown is a large-span film plastic greenhouse used for annual production in the Yangtze River Basin. The greenhouse extends north-south, with a length of 48.0m, a span of 20.0m, a shoulder height of 1.8m, and a ridge height of 6.0m; the shading system is 7.0m high.

[0055] The film plastic greenhouse includes a greenhouse frame, a sunshade system and a thermal insulation system.

[0056] The greenhouse skeleton includes an inner column 12 fixed by an inner column foundation 13 and a greenhouse arch 11 supported by the inner column 12 .

[0057] The inner columns 12 are arranged in a row in the north-south direction, and the interval between two adjacent inner columns is 4.0m. The inner column scissors bracing 121 in the middle and the arch longitudinal beam 14 in the upper part (ab...

Abstract

The invention discloses a large-span thin-film plastic greenhouse for year-round production of a Yangtze river basin region. The plastic greenhouse comprises a greenhouse framework, a thermal insulation system and a sunshade system; the greenhouse framework comprises inner stand columns and greenhouse arch frames supported by the inner stand columns; the positions, close to the top ends, of everytwo adjacent inner stand columns are connected through an arch frame longitudinal beam; each greenhouse arch frame comprises a space truss of a semi-arch-shaped structure and a plane truss of a semi-arch-shaped structure; the space trusses are symmetrically arranged on the east sides and the west sides of the inner stand columns to form greenhouse main arches; three plane trusses are arranged between every two adjacent space trusses to form a greenhouse auxiliary arch; the main arches and the auxiliary arches are connected in the south and north directions through arch frame longitudinal pullrods; the two sides of the tops of the greenhouse arch frames are provided with top ventilation openings, and the top ventilation openings are provided with ventilation windows adopting rail type window opening systems. According to the plastic greenhouse, the main truss structure and the auxiliary truss structure are adopted, so that the greenhouse structure is more stable, and the compression resistance is stronger; and a heat preservation quilt and a sunshade net are arranged above the greenhouse arch frame, so that heat preservation in winter and cooling in summer can be realized.

Description

technical field [0001] The invention relates to a greenhouse, in particular to a large-span film plastic greenhouse used for annual production in the Yangtze River Basin. Background technique [0002] Among the cultivation facilities in our country, the plastic greenhouse has the largest area of ​​use. It has the advantages of simple structure, convenient construction, and is suitable for the northern and southern climate regions of China. Most of the spans of traditional plastic greenhouses are 6m, 8m, 10m, 12m, 15m. With the continuous rise of labor prices, the demand for mechanized operations in facility agriculture is becoming more and more urgent, and plastic greenhouses can no longer meet the requirements of mechanized operations. The solar greenhouse has good thermal insulation performance, less energy consumption for overwintering production in the northern region, completely eliminated the off-season production of winter vegetables in the northern region, and has go...
