How to choose the appropriate revolving door
Author:
1、 Clarify the type and applicable scenarios of revolving doors
Rotating doors are mainly divided into three types, which need to be selected according to the usage scenario:
1. Two wing revolving doors: suitable for medium to high pedestrian flow places (such as office buildings and hotels), with a traffic efficiency of about 25-40 people/minute (data source: "Technical Specification for Building Doors and Windows" GB/T 8478-2020), with a flat emergency function and high safety.
2. Three wing revolving door: Low cost, with a traffic efficiency of 15-25 people/minute, commonly found in shopping malls and hospitals, but needs to be used with side doors in emergency situations.
3. Crystal revolving door: Designed with full glass, it has strong aesthetics and is suitable for high-end commercial buildings. However, its wind resistance performance is weak, so it needs to be installed in areas with strong winds.
>Expansion suggestion: For places with high pedestrian flow such as airports and subway stations, the combination of "revolving doors+automatic swing doors" can be used to improve traffic efficiency.
2、 Key parameter selection guide
1. Size matching:
-Single door diameter: The standard is 2.4-4.2 meters (refer to the "Technical Specification for Rotating Door Engineering" JGJ/T 454-2019), and the cost increases by about 15% for every 0.5 meter increase in diameter.
-Height: usually 2.5-3 meters, to be coordinated with the height of the building.
2. Material and safety:
-Frame material: aluminum alloy (lightweight and corrosion-resistant) or stainless steel (high-strength, suitable for outdoor use).
-Glass: Tempered glass must be used, with a thickness of ≥ 12mm, and certified by 3C.
3. Intelligent functions:
-Modern revolving doors can integrate functions such as facial recognition, infrared anti pinch (response time ≤ 0.3 seconds), speed adjustment (adjustable from 0.5-1.2m/s), etc., which need to be selected according to budget.
