Description
Technical field
The utility model relates to agricultural equipment facilities, are related to greenhouse greenhouse truss and its overall structure, and in particular to a kind of
Triangle space truss and large-span non-upright post greenhouse.
Background technique
China large-span non-upright post greenhouse (super large clear span greenhouse) current economic span is generally 12 meters to 12.8 meters,
There is greenhouse appearance span in part is larger to reach 16 meters, some has been even up to 26 meters, but the internal span both limited by structure
It is required that being provided with one or more columns.Heat-insulation system mainly has external thermal insulation quilt, inside holding quilt, inside thermal screen etc., matched logical
Wind cooling is generally film coiling system and small-sized fan ventilation.Since net span is smaller, seriously limit in China's greenhouse structure
The do mechanization operation in portion greatlys restrict the development of China's industrialized agriculture.In addition, since northwest China local climate condition is multiple
Miscellaneous, night on the daytime temperature difference is big, and therefore, in China, vast the Northwest greenhouse is all made of external thermal insulation and is kept the temperature, in mistake
Inside and outside insulation quilt part solves the problems, such as the Winter protection in northwest China area greenhouse for 10 years gone, but since external thermal insulation is by this
Be in outside greenhouse, therefore there are the serious problems of the following aspects for a long time: insulation quilt is thick and heavy, and volume paving is difficult, i.e.,
Make to be to have used electric rolling to be laid with for after all to there is a problem of that volume paving is unstable, specially greenhouse external thermal insulation not can guarantee volume and spread
Straightness, therefore greenhouse daylighting face large area is caused to shade, secondly as greenhouse external thermal insulation is thick and heavy, also causes volume to be laid with standby
Load is big, is easy to appear failure, and sleet corrodes in addition, and the service life of insulation quilt is only capable of maintaining 2-3, and use cost is high, safeguard at
This is also high；In northwest China windy area, external thermal insulation is stored in hidden dangers in project, often faces and is integrally started by wind, can not only make
