Description

Assembled color steel plate gypsum board composite suspended ceiling Technical Field The utility model relates to the technical field of assembly type buildings, in particular to an assembly type color steel plate gypsum board composite suspended ceiling. Background In the field of architectural decoration, suspended ceilings are used as important decorative and functional components of the tops of indoor spaces, and the performance and the installation mode of suspended ceilings are always important in the industry. The existing suspended ceiling installation mode is generally that a gypsum board suspended ceiling is firstly measured to determine the height and the positions of keels, then a main keel and an auxiliary keel are sequentially installed after a suspender is installed, then a self-tapping screw is used for fixing the gypsum board and processing joints, an integrated suspended ceiling is firstly measured and designed, then the suspender and a triangular keel are installed, an integrated pinch plate is inserted after an electric module is installed, inspection and debugging are carried out, wood is firstly required to be dried, anti-corrosion and fireproof, wood or light steel keels are optionally used for installation, then wood plates are spliced and subjected to surface polishing, lacquering and other treatments, however, the suspended ceiling installation mode is often dependent on a keel structure, the procedures of the keel are complex, a plurality of people are required to cooperate, a large amount of manpower and time are consumed, and the technical requirements on constructors are high, and the overall installation cost is high due to the fact that a plurality of procedures are involved and a plurality of people are required to cooperate, in the aspect of time cost, the construction period is prolonged, and the material cost of the keels and the loss in the installation process are further increased. Disclosure of utility model The utility model aims to provide an assembled color steel plate gypsum board composite suspended ceiling, which solves the problems that the prior art relies on a keel structure, the procedures are complex, a plurality of persons are required to cooperatively operate, a great deal of manpower and time cost are consumed, and the technical requirements on constructors are high. In order to solve the technical problems, the utility model provides the following technical scheme: The utility model provides an assembled various steel sheet gypsum board composite suspended ceiling, includes two assembled wallboards, two various steel sheets are all installed at assembled wallboard's top, two various steel sheet's opposite sides all is provided with U type draw-in groove, two U type draw-in groove is corresponding with two assembled wallboards, and two XPS waterproof buffering adhesive tape is all installed between U type draw-in groove and the two assembled wallboards, two be provided with from buckle overlap joint structure between the various steel sheet, and two gypsum board backing is all installed at various steel sheet's top.
