Description

Technical Field

[0001] This utility model belongs to the field of air-supported membrane structure architecture, and particularly relates to a revolving door for air-supported membrane structure architecture. Background Technology

[0002] Currently, revolving doors are commonly used for personnel access in air-supported membrane structures. A typical revolving door includes a frame, upper and lower partitions, a rotating door panel, two curved walls, and an entrance / exit. The upper and lower partitions are fixed to the frame, the tops of the two curved walls are fixed to the upper partition and frame, and the bottoms of the two curved walls are fixed to the lower partition and frame. The rotating door panel is located within the space enclosed by the upper and lower partitions and the two curved walls, forming the entrance / exit between the two curved walls. The frame is the fixed outer frame of the entire door, sealed and fixedly connected to the air-supported membrane structure. The rotating door panel is rotatably connected to the frame via upper and lower bearings. (See CN212927574U, China Utility Model Application Publication). This patented design allows the revolving door to minimize airflow (the revolving door is not completely sealed, because the air-supported membrane structure needs to both inflate the internal space and vent air outwards; both inlet and outlet have dedicated channels, so a complete seal is unnecessary). The revolving door panels have brushes and sealing strips around their perimeter, between the upper and lower partitions, and between the curved walls, providing a sealing effect. Revolving doors typically have four panels (more panels result in better sealing, but rotation is also more laborious; air-supported membrane structures generally use manual rotation). However, when people are entering or exiting, the door's sealing performance decreases when the panels rotate to the entrance / exit position, making increasing the number of panels clearly impractical. Utility Model Content

[0003] (1) Technical problem to be solved: Provide an air-supported membrane structure building revolving door, which aims to compensate for the defect that the sealing performance of the revolving door will be reduced when the door leaf rotates to the entrance / exit position when people enter and exit.

[0004] (2) The technical solution adopted by this utility model is as follows:

[0005] A revolving door for an air-supported membrane structure includes a frame, an upper partition, a lower partition, a revolving door leaf, and two curved walls. The revolving door leaf is located within the space enclosed by the upper partition, the lower partition, and the two curved walls. An entrance / exit is formed between the two curved walls. A movable sealing door assembly is installed at the outer end of the entrance / exit. The movable sealing door assembly includes an arc-shaped door, a lower arc-shaped guide rail, and an upper arc-shaped guide rail. The upper arc-shaped guide rail is fixed to the upper partition, and the lower arc-shaped guide rail is fixed to the lower partition or the ground. The top of the arc-shaped door is movably connected to the upper arc-shaped guide rail, and the bottom of the arc-shaped door is movably connected to the lower arc-shaped guide rail. A first sealing element is installed between the arc-shaped door and the curved walls and the upper partition. The lower arc-shaped guide rail and the upper arc-shaped guide rail are coaxially arranged with the revolving door leaf.

[0006] A further technical solution is that the lower arc-shaped guide rail is a plate structure, and the bottom of the arc-shaped door is provided with a first sliding groove that matches the lower arc-shaped guide rail, with the lower arc-shaped guide rail located inside the first sliding groove.

[0007] A further technical solution is that the upper arc-shaped guide rail is a frame structure, and a second sliding groove matching the top of the arc-shaped door is opened in the middle of the upper arc-shaped guide rail, with the top of the arc-shaped door located inside the second sliding groove.

[0008] A further technical solution is that a frame is provided at the edge of the curved wall and the lower edge of the upper partition at the entrance / exit, a first sealing element is provided between the curved door and the frame, and a second sealing element is provided between the curved door and the lower partition or the ground.

[0009] (3) Due to the adoption of the above technical solution, the beneficial effect of this utility model is: by setting a movable sealing door assembly at the entrance and exit of the revolving door, specifically, a movable arc-shaped door is set between the lower arc-shaped guide rail and the upper arc-shaped guide rail, and a first sealing element is set between the arc-shaped door and the curved wall and the upper partition. When the movable sealing door assembly is located at one end of the building inside the revolving door entrance and exit, the arc-shaped door is in a closed state. When the door rotates during the process of personnel entering the revolving door, the sealing performance can be almost the same as when the revolving door is stationary (when the door is in contact with the curved wall). After rotating the revolving door to the position (when the door is in contact with the curved wall), the arc-shaped door is pushed to open it, and then the arc-shaped door is closed after entering.

[0010] The purpose of using an arc-shaped door is to avoid interfering with the operation of the revolving door itself. The arc-shaped door is coaxial with the revolving door leaf and its inner diameter is larger than the outer diameter of the curved wall. Attached Figure Description
