Abstract

A steel skeleton of a greenhouse shed comprises an inner chord and an outer chord which take a circular arc shape as a whole and are connected by a 'zigzag' connecting rib in the middle. The steel skeleton is characterized in that the outer chord is made from an 'I'-shaped sectional material which comprises a wide surface and a narrow surface, the surface of the outer chord connected with the 'zigzag' connecting rib is the narrow surface, and the other surface is the wide surface for uplifting a shed film. The 'I'-shaped sectional material of the greenhouse shed integrates the advantages of strong bending resistance of a steel pipe and long corrosion resistance time of reinforcing steel bar overcomes the disadvantages of poor corrosion resistance and short service life of the steel pipe and poor bending resistance of the reinforcing steel bar, and has functions for unique innovation of laying a double-layer shed film and internally providing an insulating layer so that the greenhouse shed constructed by the sectional material improve snow resistance, wind resistance and internal thermal insulation, thus filling a gap for facility agriculture.

Description

technical field [0001] The invention relates to a steel frame of a greenhouse. Background technique [0002] The greenhouse of present single film comprises outer string 11 and inner string 10, as figure 1 , the outer chord 11 is a steel pipe, and the inner chord 10 is a steel bar, or as figure 2 Shown, inner and outer chords 10,11 are steel bars. Made of steel pipes, the steel pipe wall is thin and not corrosion-resistant, and the wall is thick and the cost is high. The problem of corrosion resistance is solved by making steel bars, but the bending resistance is very poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a steel frame for greenhouses that combines the advantages of strong bending resistance of steel pipes and long corrosion resistance of steel bars with simple production technology and practicality. [0004] In order to solve the above problems, the present invention takes the following techn...
