Problems solved by technology

[0007] The present invention solves the technical problem of the existing greenhouses with poor thermal insulation in winter and poor cooling ability in summer, and provides an assembled steel frame greenhouse, which adopts the "suspension beam structure" in the light steel structure of the building to optimize the greenhouse structure, and basically does not increase the On the basis of construction cost and no reduction in building safety, the function of "one-layer structure, multi-layer coverage" is realized, and the ability of heat insulation and heat preservation in winter and shading and cooling in summer is enhanced.

Embodiment Construction

[0032] The embodiments will be described in detail below in conjunction with the accompanying drawings.

[0033] A method for designing a prefabricated steel-frame greenhouse, illustrated by taking a greenhouse with a span of 8 meters as an example, includes the following steps:

[0034] S1: Determine that the ceiling height of the greenhouse is 4 meters, the shoulder height is 2 meters, and (top height-shoulder height) / span=0.25 of the entire greenhouse.

[0035] S2: Reasonable axis streamline design between the high arc points of the two shoulders

[0036] The reasonable axis calculation formula is: Y=4(B-X)HX / B 2 , where Y is the height of each arc point, H is the top height, B is the span, and X is the horizontal distance. According to different X values, the height of each arc point on the reasonable axis between the two shoulder high arc points is calculated.

[0037] Here, the reasonable axis span between the high arc points of the two shoulders is 6 meters (minus the...

Abstract

The invention provides an assembled steel frame greenhouse design method and a structure thereof. The method is adopted that the top height is increased, an ideal ratio of (top height-shoulder height) / span is firstly determined and reasonable axial line streamline design is performed between arc points of two shoulder heights, and the problem that the difference of an actual ratio of (top height-shoulder height) / span and the ideal ratio is large is solved; 'a beam string structure' in a building light steel structure is adopted to optimize a greenhouse structure, on the basis of not increasingthe construction cost and not lowering the building safety, the functions of 'a one-layer framework and multi-layer coverage' are achieved, and the winter heat insulation capability and the summer shading and cooling capability are strengthened.

Description

technical field [0001] The invention belongs to the technical field of agricultural greenhouses, and in particular relates to a design method and structure of an assembled steel frame greenhouse. Background technique [0002] The prefabricated galvanized steel pipe plastic greenhouse is a national stereotyped product designed by the China Agricultural Engineering Design and Research Institute in 1982. It has the advantages of uniform specifications, simple installation, convenient film fixing, and low construction cost. It has been widely used in the north and south of my country. Seedlings or cultivation of horticultural plants should be advanced in Spring Festival or delayed in autumn. The prefabricated galvanized steel pipe plastic greenhouse is an industrial product produced in a factory. After more than 30 years of improvement and development, more than 20 series of standards and specifications have been formed. [0003] The main specifications and structure of the pref...
