Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of greenhouse construction, in particular to a fast-assembly sunlight greenhouse using GFRP material and a fast-assembly method thereof. BACKGROUND

[0002] As an important part of modern agriculture, greenhouses are widely used in northern regions. The main function of a greenhouse is to produce crops out of season. Traditional greenhouses cannot be used in high-latitude regions due to material and construction process limitations. Moreover, since agricultural production is a long-cycle industry, high-cost materials and technologies are not suitable for agricultural production, making it difficult for many products to be widely used in the greenhouse industry.

[0003] Traditional greenhouses use concrete beams to fix steel frames. The steel frames are prone to corrosion in the high-temperature and high-humidity environment inside the greenhouse. In addition, the existing fast-assembly greenhouse uses color steel tiles as the outer wall insulation material, which cannot be bent at the corner of the rear slope and rear wall of the greenhouse, and cannot be sealed.

[0004] The disadvantages of the prior art are as follows.

[0005] (a) The traditional greenhouse steel frame is fixed in the cast concrete beam. In the high-temperature and high-humidity environment of the greenhouse, the steel frame corrodes too quickly, affecting the service life.

[0006] (b) Traditional sunlight greenhouses require a large amount of steel, and the greenhouse frame itself is heavy and not suitable for installation, and has weak load-bearing capacity.

[0007] (c) The fast-assembly structure of the steel frame greenhouse cannot completely eliminate welding work.

[0008] (d) Color steel tiles are difficult to bend, and the joints between the rear slope and the rear wall of the greenhouse are not sealed, affecting the insulation effect, and the iron sheet of the color steel tile is not corrosion-resistant. SUMMARY
