Description

Technical Field

[0001] The utility model relates to the technical field of building decoration construction, in particular to a cantilevered dislocated stepped ceiling structure. Background Art

[0002] Gypsum board ceiling is a common decoration method in the decoration process, but due to the influence of floor height, pipeline layout, fire protection facilities, etc., the ceiling height may not reach the expected height. In order to have a more comfortable ceiling height, the ceiling elevation is often partially adjusted to meet the ceiling height, and it can also show a sense of hierarchy and enhance the aesthetics.

[0003] In the indoor corridor area of ​​many buildings, one side of the corridor is an office or rest area, and the other side is a lofted area. In order to meet the fire protection design requirements, a fireproof roller shutter needs to be installed on the lofted side. The fireproof roller shutter needs to be covered and beautified during the decoration stage because of its own supporting facilities, such as guide rails, motors, etc., and the motor is generally hidden in the ceiling, but the height of the motor will affect the ceiling elevation. When the floor height is low, if the motor bottom elevation is used as the ceiling elevation, the finished surface of the ceiling may not meet the net height requirements. The usual practice is to make a stepped ceiling system such as the one used in CN111155700A, but when the corridor width is limited and the step height is small, the solution of adjusting the ceiling elevation by configuring hangers of different lengths as mentioned above may cause construction inconvenience and waste of materials. The utility model provides a cantilevered staggered stepped ceiling structure to solve the above problems. Utility Model Content
