How to design a tall landscape glass greenhouse? A case study of a glass greenhouse with a height of 10 meters at the shoulder
Landscape glass greenhouses refer to tall and large glass greenhouses used for landscape display, planting tall landscape plants, leisure ecological restaurants, botanical garden venues, park reception centers, etc. Generally, this kind of glass greenhouse requires large span, large bay, high space, and large length and width. Therefore, the structure of the glass greenhouse and the ventilation and cooling requirements of the internal space are very high. Today, I will share with you a case analysis of a large glass greenhouse. We Mainly from the topography and greenhouse structural materials to bring you an analysis.
1. The construction site and use of the landscape glass greenhouse The construction site of the glass greenhouse is Hubei, which is close to the urban area. The owner has reserved an open space in the center of his botanical garden for the landscape glass greenhouse, and the interior planning is for leisure landscape. There is also an ecological restaurant and a play center. The climate of Shiyan City is hot in summer and lasts for a long time, so it is particularly important to do a good job of ventilation and cooling design.
2. The size design of the glass greenhouse is 84 meters from east to west, 12 meters per span is divided into 7 spans, 128 meters from the north to the south, and 8 meters for the bay, of which 128 meters is divided into 64 meters in the south area and the terrain is 2 meters high, and the north side is 2 meters high. The 64-meter terrain is two meters short. However, since our greenhouse is located in a low-lying place in the center of the entire botanical garden, in order for tourists to see the landscape glass greenhouse on the mountain, it is a whole effect. Therefore, the height of the column on the south side is 10 meters, the height of the column on the north side is 88 meters, and the top of the greenhouse is 10 meters high. It looks flat and gives a stunning visual effect.
3. Landscape glass greenhouse system and material specifications Landscape glass greenhouse has external shading system, internal shading system, fan water curtain cooling system, hot-dip galvanized steel frame on-site bolt connection, surrounded by Ford blue hollow tempered glass, and top covered with SABIC Imported sun panels. Among them, because the east-west distance of the greenhouse is 84 meters, which exceeds the cooling limit distance of the fan water curtain, we adopted the method of hanging the water curtain in the middle, installing fans on the east and west walls, and staggered peak ventilation for cooling.
The specifications of the greenhouse columns are 200*200*5.0 hot-dip galvanized square tubes, the upper and lower trusses of the greenhouse truss beams are 60*60*2.5, the thickness of the greenhouse gutter is 2.5mm*375, the surrounding maintenance beams are 50*50*2.0, and the greenhouse external sunshade columns and The transverse beam is 50*50*2.0. The surrounding glass is 5+9+5 double-layer hollow tempered, and the outer layer is coated with Ford blue. The top covering material is 8mm imported hollow sun panel, which is light in weight, high in heat insulation and safety factor, and is fixed by aluminum profiles.
