Description

Assembled ceiling and installation method

Technical Field

The application relates to the technical field of suspended ceilings, in particular to an assembled suspended ceiling and an installation method.

Background

The suspended ceiling decoration is one of the most common decorations in interior decoration, and suspended ceiling structure includes furred ceiling connecting device and furred ceiling board usually, and furred ceiling connecting device fixes on the building body and provide the fixed department of furred ceiling board, and the furred ceiling board generally adopts gypsum board, light metal decorative board, PVC decorative board etc.. Suspended ceiling generally adopts the jib to be fixed with the roof, adopts limit keel component and wall to be connected to guarantee the firm of suspended ceiling.

Among the correlation technique, can refer to the chinese patent that application publication number is CN105464273A, it discloses a novel furred ceiling mounting structure, it is by the main joist, hang the piece, the connecting piece, secondary joist and furred ceiling board are constituteed, it is fixed with the jib that a jib connector is passed through to hang one end, it is fixed with the main joist that the other end of piece passes through the main joist connector, the connecting piece is connected with the main joist through the fashioned elbow structure of its one side, the both sides at the top of secondary joist "worker" font can the holding make it fixed with the connecting piece in slot structure, the lower part both sides of secondary joist "worker" font are connected with the groove structure cooperation of furred ceiling board side respectively, beneficial effect is: the furred ceiling board side shaping is fluted structure, and is pegged graft fixedly with fossil fragments through groove structure, compares than traditional fix with screw mode, and it is convenient to have the equipment, dismantles advantages such as convenient, and the face of furred ceiling board does not receive destruction because of the installation simultaneously.

With respect to the related art among the above, the inventors consider that the following drawbacks exist: the main joist is fixed generally and is that the staff fixes, though can use the spirit level to detect the levelness of main joist at fixed in-process, but the length of general main joist is longer, therefore the spirit level can only generally be placed main joist a place, thereby the accuracy of the main joist levelness of detection is relatively poor, consequently can be in uneven state after the main joist is installed to the furred ceiling board, consequently the atress inequality of furred ceiling, thereby the security that leads to the furred ceiling is lower.
