The new construction system of grilled lightweight concrete masonry ceiling solves the problem of casting flat slabs, roof slabs, stairs and similar structures. It is rational, efficient in casting, it has excellent conditions of load bearing, temperature insulation properties, moisture protection and fire resistance. The new system consists of the following elements: prefabricated steel-concrete girder (1), prefabricated lightweight concrete or micro-concrete lower threshold (2), prefabricated lightweight ceiling block (3), single-layered or three-layered, lateral ribs (4), reinforced and made of lighweight concrete or micro-concrete, prefabricated lightweight upper threshold (5), thin mortar layer (6) made of cement or similar materials; all these elements, by their forms and dimensions, form a compatible system. The structure can be cast manually without any supporting because the structure is selfbearing. The structure is of a grill type with a hidden compressive slab. Due to the prefabrication the structure is camber. The ceiling block is produced as a final structural element. The final ceiling is covered by a thin mortar layer. The adaptability of the system to different forms of houses and buildings, by using a few types a precast elements, contributes to its rationality and wide applicability. The regular form of the elements makes possible the application of different parts of buildings of various forms; thus, architects and engineers have a greater creative freedom in, the design of houses and buildings. |
