Description

Technical Field

[0001] The utility model relates to the technical field of membrane structure stands, in particular to an assembled membrane structure stand for sports fields. Background Art

[0002] Membrane structure is a structural system that combines architecture and structure. It uses high-strength flexible film materials and auxiliary structures to generate a certain pre-tension stress inside it in a certain way, and form a certain spatial shape under stress control. It is a narrow structure type that serves as a covering structure or the main body of a building and has sufficient rigidity to resist external loads.

[0003] The new patent with the authorization announcement number CN217975599U discloses a membrane structure sports field grandstand with good stability, which specifically relates to the technical field of membrane structure grandstands, including a grandstand body, a membrane structure, three fixed columns and two supporting rods. The membrane structure is an arc-shaped structure, and three connecting seats 1 are fixedly installed at equal intervals on the front side of the top of the membrane structure. The bottom of the fixed columns are fixedly installed with mounting seats, and the upper side of each fixed column is fixedly installed with a connecting kit. The rear side of the membrane structure is fixedly connected to the front sides of the three connecting kits, and each of the front sides of the connecting kits is fixedly installed with a connecting seat 2, and a connecting piece is arranged between the connecting seat 1 and the connecting seat 2. The utility model provides a connecting piece, a supporting rod and an auxiliary supporting piece. The connecting piece connects the membrane structure from the upper side, and the supporting rod and the auxiliary supporting piece support the membrane structure from the lower side, thereby fully ensuring the stability of the membrane structure during use.

[0004] The device, by setting connecting pieces, supporting rods and auxiliary supporting pieces, connects the membrane structure from the upper side with the connecting pieces, and supports the membrane structure from the lower side with the supporting rods and auxiliary supporting pieces, fully ensuring the stability of the membrane structure during use. However, currently the membrane structure is usually kept in an unfolded and laid state for a long time, and the material of the membrane structure is relatively soft. After rain and snow, the membrane structure is prone to form depressions and accumulate rain and snow. After being eroded by rain, snow or weather, the membrane structure in the depression is more easily damaged. When the membrane structure is not in use, the membrane structure is easily eroded by rain and environmental pollution, thereby shortening its service life.
