Glass greenhouse

Venlo type greenhouse is a large span greenhouse with the most extensive area and the fastest spreading speed, which plays a very important role in realizing the agricultural modernization and promoting the development of rural economy. However, with the continuous diversity of Venlo greenhouse uses and the continuous popularization throughout the country, there are more and more potential safety risks, so it is imperative to verify its safety. Besides, the Venlo greenhouse structure corresponding to the different design in different regions is also an important method to reduce its construction cost. The Venlo greenhouse originated in Venlo Dutch town in the 1950s and was named after it. The article is edited and sorted out by manager Zhang of Jianda greenhouse because of its advanced structure form, developed standardization degree, which is beneficial to realize the agricultural modernization of our country. Compared with the traditional double-slope greenhouse, the Venlo greenhouse is divided into three spires. The greenhouse has small roof, rain trough, long span and steel structure.

The roof members of the Venlo greenhouse structure adopt fine galvanized steel, on one hand as the roof bearing strip, on the other hand as the roof covering material inlay, which makes the roof cover the transparent board with the largest area. At the same time, the section size of the tank is reduced and the transmittance is improved under the premise of structural safety and drainage performance: another characteristic of Venlo greenhouse is less steel use and larger span; As a result of the design of the roof with its three spires, the wind load and water accumulation load are small, which is helpful to reduce the section size, increase the span and further reduce the steel use. At the same time, because the Venlo greenhouse adopts the small spire roof structure to reduce the overall height of the structure, it can reduce the wind load of the structure without changing the column height; At the same time, compared with the traditional double-slope roof, it has a larger force area and can withstand a large snow load. At the same time, it is more favorable to drain rain and snow into the flume at the top of the column, avoiding the accumulation of snow load on the roof and reducing the roof load. Venlo type greenhouse adopts the way of external sunshade frame to control the illumination, mainly adopts two ways to install side fan and roof window to exhaust air, so its ventilation area is nearly 20% more than that of traditional greenhouse.

All in all, the Venlo type greenhouse benefits from its advanced structural form, light and high strength material properties, can increase the transparent area of the greenhouse, reduce the wind and snow load of the greenhouse roof, and then reduce the cross section size of the structural members, reduce the amount of steel used, and the ventilation area of the exhaust fan can reach nearly 20% more. In addition, the production standardization of Venlo greenhouse is high, and it is developing in the direction of intelligence. In addition to the planting effect of traditional solar greenhouse, it can be mainly used in potted crop seedling and seed production. And other flower seedlings and other special crops cultivation. Besides, the long span Venlo greenhouse can also be used as the main structure of fruit and vegetable plant exhibition, flower, bird, fish and insect market and agricultural tourism culture.

Compared with the traditional solar greenhouse, the Venlo greenhouse has a large span, high land use rate, high degree of production standardization, convenient for mechanized and large-scale agricultural production, and its production advantages are obvious. At the same time, with the continuous improvement of agricultural science and technology level, the scientific and technological degree of greenhouse facilities and equipment has been continuously improved, and various environmental testing and intelligent control equipment research and development have been updated and put into production. Light steel frame greenhouses, including Venlo type greenhouses, are becoming more and more intelligent and in line with the development direction of modern agricultural production.
