To accurately position the surrounding walls according to the design elevation, it is necessary to snap clear and precise lines. These snapping lines must be strictly adhered to and allow for a maximum horizontal deviation of ± 5mm.
Let's talk about fixing the side keel along the elevation line. The side keel is an essential component that seals the edge of the ceiling. Typically, side keels come in a 25*25MM specification and should match the PVC gusset plate's color. To secure it firmly, the side keel is fixed on the wall column using cement nails. This is a crucial step that ensures the ceiling's structural integrity and prevents any issues that could arise from unsealed edges.
To ensure the proper installation and integrity of the PVC gusset plate finish, the keel position line must be determined based on the size of each decorative panel. These gusset plates are usually not able to be cut into blocks, so the size of the ceiling skeleton must be arranged accordingly. The layout of the finish should be complete, with symmetrical and uniform edges when necessary. The keel frame can then be arranged based on the size of the gusset plate and the area of the ceiling, with the position line marked on the upper edge of the elevation line. This meticulous planning is essential for a flawless finish that will meet the highest standards of quality and aesthetics.
The selection of the distance between the lifting points of the main keel must comply with the design's recommended series. The keel's middle section must have an arch, with an arched height not lower than 1/200 of the room surface span. After installing the keel, the position and height may need corrections without delay. To supervise the leveling of the keel frame, begin by pulling out the vertical and horizontal elevation control line, start assembling and modifying the suspender's hanging height from one end. Even out the major surface before adjusting certain single keels with curved edges until the flatness reaches the required level.
To ensure stability, the suspender in a ceiling system must be strong and straight, with the ability to bear weight. If the suspender is extended, it should be securely overlapped and welded with a uniform and full weld. The suspender should also be treated with antirust to prevent corrosion. Additionally, the suspender must not be more than 300mm from the end of the main keel as this may cause the main keel to fall, and to avoid this, a secondary keel (medium or small) close to the main keel should be installed.
To ensure the integrity of the ceiling framework, it is imperative that the main and secondary keels are correctly positioned and levelled. The installation of connectors should be purposefully dislocated for optimum stability. A thorough inspection of the framework is necessary to guarantee that it meets the required specifications. Only after the firmness and reliability of the ceiling are assured can further construction proceed.
When fitting the PVC gusset plate, it is crucial to ensure that the secondary bone is straightened. Not only that, but the gusset plate itself must be completely flat without any warping. Additionally, the ceiling plane cannot deviate more than 5mm from the specified flatness error. This is important to maintain overall structural integrity and prevent any potential issues which may arise from inaccurate installation.
