Semicircular steel frame structure

Abstract

The invention discloses a semicircular steel frame structure. The semicircular steel frame structure comprises a plurality of stand columns, a plurality of upper transverse beams, four lower transverse beams, and a plurality of arc-shaped top frames, wherein the four lower transverse beams are connected to form a square bottom frame; the upper transverse beams are arranged corresponding to the lower transverse beams, and at least four stand columns are connected between the upper transverse beams and the lower transverse beams; and each arc-shaped top frame is correspondingly arranged above each upper transverse beam, and reinforcing ribs are arranged between each upper transverse beam and each arc-shaped top frame. The semicircular steel frame structure disclosed by the invention has thebeneficial effects that by adopting a steel frame structure type framework fixed on the ground and a support structure connected with the steel frame structure type framework, compared with a common plastic greenhouse, the firmness is greatly improved, and the service life is greatly prolonged; the height of the steel frame structure can reach 2 to 2.5 m, and additionally, the height of the support structure is 0.5 to 1 m, so that the normal production of various crops is basically guaranteed without obstruction by narrow space; and a thin film covers the greenhouse and is easy to cover and open, so that the environment conditions, such as sunlight radiation and air circulation, for the normal growth of plants can be simulated.

Description

technical field [0001] The utility model relates to a steel frame structure, in particular to a semicircular steel frame structure. Background technique [0002] Plastic greenhouses have been widely used in agricultural production activities such as vegetable planting, flower cultivation and seed breeding around the world, but most of them are composed of frame support structures supplemented by plastic films. The plastic greenhouses used for flower cultivation and seedling breeding in winter are generally relatively strong, and equipped with supporting facilities such as rainproof, windproof, and cold protection, but the production process is long and the cost is high, and the plastic covering is generally not easy to open casually; vegetable planting The cost of plastic greenhouses is relatively low. Most of them are framed by bamboo poles or steel frames. The plastic covering can be easily opened for ventilation. The height is also lower. And one is durable, can be used...
