Description

Technical Field

[0001] The invention relates to the field of decoration engineering, in particular to a height-adjustable ceiling structure and a construction method thereof. Background Art

[0002] Traditional suspended ceiling structures typically consist of three main components: hangers, keel frames, and decorative panels. The process for this type of ceiling construction is as follows: first, draw lines to determine the hanger points; then install the primary keel; then install the secondary keel; then install the secondary keel; then install the decorative panels; then, treat the gaps in the gypsum board; apply putty; and finally, paint twice; finally, directly install inorganic mineral materials and plastics. The construction disadvantages of this type of ceiling construction include: 1. Environmentally unfriendly: Paint contains some formaldehyde, so even a simple indoor gypsum board ceiling requires paint for the final finish. Therefore, environmental and health considerations are often unsatisfactory, and when color is desired, paint must be used, which increases the formaldehyde content. 2. Long construction time: Due to the numerous steps involved in suspended ceiling construction, from screw threading, installing keels and hanging panels, applying putty, and painting twice to completion, a single area of the ceiling can take at least 5-7 days to complete. This last three steps, especially, can be extended by weather and temperature. 3. Low safety: Safety is a key consideration in interior decoration, especially fire safety. While gypsum board or other mineral-based ceiling materials are inherently fireproof, their fire resistance is limited. They rely primarily on two layers of paper for support. When the paper burns, the gypsum board disintegrates, easily causing a potential roof collapse. 4. The labor and material costs for a standard gypsum board ceiling range from approximately 200 to 300 yuan, though this may be higher in some cities. The price of a shaped or stepped ceiling increases by approximately 80 yuan per square meter. Summary of the Invention
