Description

Technical Field

[0001] The invention relates to the technical field of building suspended ceilings, in particular to a nail-free modular suspended ceiling structure. Background Art

[0002] Suspended ceiling refers to a kind of decoration on the top of the living environment of a house. Simply put, it refers to the decoration of the ceiling, which is one of the important parts of interior decoration. Suspended ceiling has the functions of heat preservation, heat insulation, sound insulation and sound absorption. It is also a hidden layer for electrical, ventilation and air conditioning, communication and fire protection, alarm pipeline equipment and other projects.

[0003] Home decoration ceiling is a common part of home decoration. The classification of ceiling varies according to the material of the decorative board. The main classification of ceiling is based on the decoration material of the ceiling, which includes: light steel keel gypsum board ceiling, gypsum board ceiling, mineral wool board ceiling, plywood ceiling, special-shaped long strip aluminum gusset ceiling, square painted aluminum gusset ceiling, painted glass ceiling, aluminum honeycomb perforated sound-absorbing board ceiling, whole room duplex ceiling, etc.

[0004] In the construction of light steel keel gypsum board ceiling, the usual construction process is to first use light steel keel or wooden square to build the internal skeleton of the required ceiling type on the top surface of the building. During the erection process, the connection and leveling of the keel are connected and fixed by self-tapping screws. This method has the following disadvantages: 1. The entire leveling process is that the construction workers move the keel up and down by hand and adjust it according to the spirit level. However, when the height of the skeleton is adjusted to the required level, the level is not rigid, and deviations may occur at any time when nailing. 2. When nailing, a large force is required to make the self-tapping screws penetrate the keel, and the labor intensity is very high. 3. The installation efficiency of the gypsum board module is low. Therefore, it is an inevitable demand to design a ceiling structure that can be quickly leveled and reduce the intensity of work. Summary of the invention
