What is a revolving door?

The revolving door technology is imported from abroad, and its shape and high style The design becomes the finishing touch of the building.

The main design concept of the revolving door is energy saving, which prevents the interior of the building and The direct channel between the exterior makes it a buffer device, minimizing heat loss.

The following is explained by Huajian Craftsmanship Society and Huajian Environmental Design Institute The functions and applications of automatic revolving doors!

1. What is a revolving door

Revolving door is a type of door, often divided into two-wing, three-wing and four-wing automatic revolving doors.

The design principle of the revolving door is: it can be open and closed at the same time. Effective energy saving.

It remains open outward and closed internally. It is windproof, dustproof, and noiseproof. It can effectively prevent outdoor wind from entering the room and causing backflow to high-rise buildings, which can effectively save the use of heating and cooling.

1.1Composition:

Rotate The door consists of three major components:the fixed frame, the central axis assembly, and the rotating assembly. : 1px;\”>(1) Fixed frame:The fixed frame consists of upper support components and columns, upper and lower docks and fixed hanging boards.

(2) Rotating component:The rotating component is provided byComposed of door closer, display box, rotating ceiling and door assembly.The rotating component is used to open and close the door.

(3) Central axis component:The central axis assembly is the driving system of the automatic revolving door. It is the driving mechanism that starts and closes the automatic door under the control of the electronic control system. It consists of a reduction motor and a driving mechanism.

1.2Surface treatment:

Stainless steel plate, pure copper plate, fluorocarbon spraying and other processes.

1.3 Market price:

Taking first-tier cities as an example, the price of two-wing revolving doors ranges from 80,000 to 200,000 yuan per set. The specific price is mainly based on the actual local conditions.

3. Advantages and Disadvantages

01 Advantages:

1. Beautiful appearance:The high-style design of the revolving door has a decorative effect on the building.

2. Good sealing performance and energy saving: It can separate indoor and outdoor air, play a buffering role in the room, and reduce the energy consumption of indoor air conditioning. Waste.

02Material shortcomings:

1. Relatively expensive: Compared with ordinary sliding doors, revolving doors are relatively expensive.

2. Potentially dangerous: If the safety sensors in the door wings and door frames, and the gap between the rotating page and the door frame are not installed standardly or the quality is substandard, then the revolving door will be potentially dangerous. .

4. Scope of use and purpose

Because of its good energy-saving effect, revolving doors are often used in public buildings in the north and where the foyer of the building is small and needs to be buffered. Public buildings

For example: Hospitals, star hotels, large shopping malls, government departments, Grade A office buildings and other public places.

5. General construction drawings of revolving doors

a Construction sequence:

Elastic line →Install the bracket and position the axis →Install the door top and rotating wall →Install the door leaf →Manual debugging →Install the control system.

b Points to note:

1.Four door leaves should maintain an included angle of 90 degrees, and three door leaves should maintain an included angle of 120 degrees.A certain width of gap should be left above and below.

2. The door body needs to rotate smoothly, have uniform strength, consistent gaps, and no jamming. No noise.

3. Automatic revolving doors are generally deepened, processed and processed by professional suppliers. Installation andfinishing are just for coordination and cooperation to deal with closing issues.
