Description
Technical Field
[0001] The utility model relates to the technical field of air film buildings, in particular to a high-efficiency passage door for an air film warehouse. Background Art
[0002] Air-supported buildings refer to a building structure system that uses special building membrane materials as the outer shell and is equipped with a set of intelligent electromechanical equipment to provide positive air pressure inside the air-supported building to support the main body of the building. Air-supported buildings are new building structures supported by the difference in internal and external air pressure. Within a safe range, the greater the air pressure inside the air membrane, the higher the ability to withstand wind loads and snow loads, and the less likely the air-supported building will deform, and the safer it will be. Usually, the difference in internal and external air pressure is 250Pa to 300Pa.
[0003] After searching, the existing Chinese patent publication number is: CN215718362U, which provides an air-film storage high-efficiency passage door. This patent can effectively resist the extrusion of external forces by fixing the first support plate and the second support plate through an iron rod when natural forces such as excessive wind are too strong, and connecting them to the inner wall of the rolling door. At the same time, the first fan-shaped protective plate fixedly installed on one side of the first protective plate slides inside the first protective slide rail fixedly installed on one side of the second connecting rod, and at the same time, the second fan-shaped protective plate installed on one side of the first support plate slides inside the second fan-shaped protective plate fixedly installed on one side of the second protective plate. This can ensure that the rolling door is not damaged by the extrusion of external forces during the winding process and in the closed state, so that it can be used normally, and can effectively resist the damage to the rolling door caused by excessive external force when the rolling door is closed.
[0004] Although the above patent can protect the rolling door from damage caused by external forces, the above-mentioned air-supported storage high-efficiency passage door still has the following problems: However, the protection effect of the device is not high. When transport vehicles need to enter and exit the air-supported building and many people or people enter and exit the air-supported building frequently, the air-supported building will be opened for a long time, which will cause the internal air pressure to drop. In addition, due to the pressure difference between the inside and outside of the air-supported building, the inner side of the door is subjected to force, making it difficult to open each time. The door is easily damaged, and there is no fire safety alarm equipment.
