Agriculture Flower / Vegetable Plastic Film Greenhouse With Inside
Shadow System
Introduction And Features
The two main characteristics of a multi-story film greenhouse are
simple structure and flexible form. The simple multi-story film
greenhouse is to remove some of the configurations in the G-span
multi-story film greenhouse. It is mainly applicable to grape
shelters, strawberry cultivation, crop seedlings, etc. It mainly
has the following two characteristics. In addition, the maintenance
framework structure of multi-story film greenhouses needs regular
maintenance. The covering material should improve the anti-cracking
and anti-aging ability, can resist wind and sun, and achieve the
purpose of light transmission and heat insulation. Therefore, it is
necessary to take good reinforcement measures and repair any leaks
in time.
(1) Simple structure
Due to the characteristics of the covering material, the
load-bearing structure, solid film system, and installation
requirements of the plastic greenhouse are relatively simple. The
load-bearing structure is made of hot-dip galvanized light steel or
ordinary steel structure. Generally, the hot-dip galvanized light
steel structure is adopted, and the assembly structure is better.
The main part of the steel frame of the greenhouse is mainly
composed of columns, four surrounding beams, top arches, top pulls,
beams, stilts, gutters, etc. The top longitudinal members are used
as tie rods, which greatly simplifies the structure and reduces the
use of The amount of steel. At the same time, when the greenhouse
uses a covering material to connect to the roof non-mechanically,
the roof only bears the gravity load and normal wind pressure, and
the transmission of wind pressure to the gutters and columns
greatly optimizes the stress of the greenhouse structure.
(2) Flexible and diverse sizes
Due to the structural characteristics of multi-span greenhouses and
the development of large-scale multi-span film greenhouses, there
are many factors affected by regional customer needs and other
factors. Countries around the world carry out plastic greenhouses
based on their own standards. Production and promotion. Therefore,
a large number of plastic film greenhouses of different forms and
specifications are formed, such as dome-shaped greenhouses with
different spans, heights and roof shapes, double-arc-shaped roof
greenhouses, saw-tooth greenhouses, small-arch multi-roof
greenhouses, etc . Because of this, it has been difficult to
summarize and describe the individual sizes of plastic greenhouses
so far. This allows flexible design of spans and bays according to
customer requirements to meet the design needs of different terrain
sizes.
Use Tips
The maintenance of a multi-span greenhouse building is mainly the
maintenance of the skeleton structure. For the covering material,
it is mainly to improve the anti-cracking and anti-aging ability to
resist the wind and the sun and achieve the purpose of light
transmission and heat insulation. Therefore, it is necessary to
take good reinforcement measures and repair any leaks in time. For
greenhouses that have been used for a long time, the film will be
stained with dust, which will greatly reduce the light
transmittance.
