How to Suspend Ceiling for Prefabricated Floor Slab of House

For the ceiling suspension of the prefabricated floor slab of a house, gypsum board ceilings or integrated ceilings can be used, and the appropriate plan should be selected according to the type of prefabricated floor slab and the usage scenario.

Gypsum Board Ceiling

For the prefabricated slab ceiling of an old house, if there is unevenness, directly applying putty may lead to peeling and falling off in the future. In this case, a gypsum board ceiling is a good choice. Its principle is to build a keel frame below the prefabricated slab and fix the gypsum board on the keel to form a flat ceiling surface. This method can not only cover up the unevenness of the prefabricated slab but also achieve certain造型设计 (shape designs) through the plasticity of the gypsum board, enhancing the aesthetic appeal of the space. During construction, it is necessary to ensure that the keel is firmly fixed to avoid deformation of the keel due to uneven load-bearing of the prefabricated slab, which in turn affects the flatness of the gypsum board ceiling.

Integrated Ceiling

• Old-style prefabricated slab balcony: The load-bearing capacity needs to be the focus. First, understand the load-bearing design specifications and safety limits of the balcony prefabricated slab, as the integrated ceiling and its accessories will increase the load on the balcony. If it exceeds the load-bearing capacity, safety issues may arise. During construction and design, the feng shui aspect can be reasonably arranged according to personal beliefs and needs, and ventilation should ensure smooth air circulation. At the same time, appropriate ceiling materials should be selected to ensure they match the balcony decoration materials and home style, and the sturdiness of the materials and space utilization should also be considered.
• General cases of using prefabricated slabs for integrated ceilings:
  • Structural issues: Prefabricated slabs usually cannot be freely bent and processed. If the integrated ceiling requires complex shapes, the prefabricated slabs may not be able to meet the requirements, and reasonable design should be carried out according to the characteristics of the prefabricated slabs.
  • Installation issues: During installation, prefabricated slabs require the use of hooks, lifting equipment, etc. Generally, scaffolding or large machinery is needed. The installation cycle is long and the cost is high, which may affect the overall renovation cycle. Planning and budget arrangements should be made in advance.
  • Coating issues: The surface of the prefabricated slab needs to be coated, which increases the coating cost and quality control difficulty. Appropriate coatings should be selected, and the coating quality should be ensured to ensure the aesthetics and durability of the integrated ceiling.
• Bedroom with hollow cement prefabricated slabs: The ceiling should be installed on the concrete frame of the hollow cement prefabricated slab rather than directly on the prefabricated slab. Due to the hollow characteristic of the prefabricated slab, direct installation will result in a too-small load-bearing area of the ceiling, which is prone to cracks and affects the service life and safety of the ceiling. At the same time, the load-bearing capacity of the prefabricated slab should be considered. Generally, each prefabricated slab can bear a load of about 120kg. If the ceiling is too heavy, it will easily cause the prefabricated slab to crack. When selecting integrated ceiling materials and accessories, their weight should be strictly controlled.
