Description

Technical Field

[0001] This utility model belongs to the field of agricultural greenhouse technology, specifically relating to a connection structure for a multi-terrain membrane greenhouse arch frame. Background Technology

[0002] Multi-span greenhouses are a type of agricultural facility structure suitable for large-area farmland. A multi-span greenhouse consists of multiple interconnected arched or flat-roofed structures, forming a continuous covering surface. This connection method allows for a larger greenhouse area and higher space utilization. Its structure mainly includes frame materials and covering materials. The frame materials primarily include: columns, shoulder beams, arched pipes, water channels, and horizontal supports. Currently, in the construction of multi-span greenhouses, the connection of components such as columns, shoulder beams, and arched pipes is mostly done by welding. If the welds are not strong enough, the weld points are prone to breakage, affecting the structural stability. Furthermore, the humid environment inside the greenhouse, combined with agricultural pesticides, fertilizers, and water, can cause weld corrosion, shortening the service life of the multi-span greenhouse. Therefore, a connection structure that is easy to disassemble and requires no welding is needed. Utility Model Content
