Standard for main steel frame material of multi-span film greenhouse

During the five years of designing and constructing greenhouses, he has handled many planning, design and construction of greenhouse projects, and accumulated a lot of practical experience. Today I summarized for everyone a list of the main steel frame materials of the multi-span film greenhouse. The material specifications used in this list are relatively large. This specification can be suitable for Xinjiang, Northeast, Inner Mongolia, Ningxia, Gansu, It is used in Qinghai, Shanxi, Shaanxi, Heilongjiang, Jilin, and Liaoning regions because the snow volume in these areas is relatively large, and the load-bearing performance of the main steel frame of the multi-span film greenhouse is relatively high. I have also dealt with some multi-span film greenhouses with very small material specifications. The specifications are too small and are only suitable for use in areas with little or no snow in the south. picture

When talking about the main steel frame of the multi-span film greenhouse, we have to talk about the structure of the main steel frame. The multi-span film greenhouses made today are divided into two structural forms, one is a relatively high-end assembled hot-dip galvanized steel frame, and the second is a relatively low-end welded hot-dip galvanized steel frame. The prefabricated steel frame refers to a frame that is pre-processed and galvanized, and is transported to the site for direct assembly. This structure is easy to construct and install, has super good anti-corrosion performance, and relatively simple technical content. The other is a relatively simple welded steel frame. This kind of steel frame is generally used by ordinary farmers or grape cold sheds. Because it is processed and welded on-site, the anti-corrosion performance is poor, and technical clearance is required for on-site processing. The guidance of technicians, otherwise it is easy to waste materials.

The following is a detailed analysis of the material list of the main steel skeleton as follows.

(1) Main column: a 100×50×2.0mm hot-dip galvanized rectangular tube with a galvanizing thickness of 0.08—0.10mm.

(2) Side auxiliary column: adopt 50×50×2.0mm hot-dip galvanized rectangular tube, galvanized thickness 0.08-0.10mm.

(3) Sub-column on the end face: adopt 50×50×2.0mm hot-dip galvanized rectangular pipe with a thickness of 0.08—0.10mm.

(4) Side beam: 50×30×2.0mm hot-dip galvanized square pipe, galvanized thickness 0.08-0.10mm.

(5) End beam: 50×30×2.0mm hot-dip galvanized rectangular pipe with a thickness of 0.08-0.10mm. picture

(7) Horizontal tie rods: add a horizontal tie rod every 4 meters in the greenhouse, using 50*50*2mm hot-dip galvanized square pipes with a galvanizing thickness of 0.08-0.10mm.

(8) Boom: A middle boom is set on the upper part of each horizontal tie rod, which uses Ф25×2.0mm hot-dip galvanized round pipe with a galvanized thickness of 0.08—0.10mm.

(9) End horizontal diagonal brace: Ф32×2.0mm hot-dip galvanized round pipe, galvanized thickness 0.08—0.10mm.

(10) Arch pipe: An arch pipe is installed at intervals of 1 meter along the opening direction of the greenhouse, using Ф32×2.0mm hot-dip galvanized round pipe, with a galvanizing thickness of 0.08—0.10mm.

(11) Arch pipe connecting pipe: Ф25×2.0mm hot-dip galvanized round pipe, galvanized thickness 0.08-0.10mm.

(12) Gutter: 2.0mm cold-formed galvanized sheet, large cross-section can withstand 140mm/hour rainfall.

(13) Outer sunshade column: 50×50×2.0mm hot-dip galvanized rectangular tube, galvanized thickness 0.08-0.10mm.

(14) External sunshade beam: adopt 50×50×2.0mm hot-dip galvanized rectangular pipe, galvanized thickness 0.08-0.10mm.

(15) External sunshade longitudinal beam: adopt 50×30×2.0mm hot-dip galvanized rectangular pipe, galvanized thickness 0.08-0.10mm.

(16) External sunshade beam rod: Ф32×2.0mm hot-dip galvanized round tube, galvanized thickness 0.08-0.10mm.

(17) External sunshade beam diagonal bracing: Ф32×2.0mm hot-dip galvanized round pipe, galvanized thickness 0.08-0.10mm.

(18) Sunshade drive shaft: Ф42×3.75mm hot-dip galvanized round tube, galvanized thickness 0.08-0.10mm.

(19) Sunshade push rod: Ф32×2.0mm hot-dip galvanized round tube, galvanized thickness 0.08—0.10mm.
