Definitions
- This completely reinforced lightweight concrete halls and houses construction system solves the following problems: quick and rational building, cast in situ, partial or complete precasting and a high level of rough work finishing.
- the adaptability of the system to different forms of halls and buildings by using a few types of precast elements contributes to rationality and has wide applicability.
- the existing lightweight concrete systems which solve, to a certain extent, the mentioned technical task are Ytong (Europe), Leca (Germany), Lytag (Britain) and systems based on expanded clays such as Aglite (Britain), Gravelite (U.S.A.), Solite (Canada) and Liapor (Sweden) and systems based on the use of lightweight concrete made with fly ash.
- the main roof beam has cross section of I type instead of T type, with smaller volume of concrete content for the same span and load capacity.
- the wall panel reinforcement is assembled as truss or frame form instead of the mixed reinforcement structural form.
- the main roof beam has cross section of I type sloped on both sides instead of non sloped I beam.
- the beam girder of the cross section of T type has reinforcement of the upper zone assembled as clear truss, instead of local frame.
- the columns are made of mass density over than 1500 kg/m3 with separate assembled column bottom.
- the principle of complete reinforcement has been applied to lightweight concrete roof beam and slab, ceiling beam and slab, girder beam, facade panel and column. This principle enables an almost complete transfer of compressive, tensile and shear stresses into the reinforcement. Hence, the lightweight concrete body becomes a secondary structural media for local and global stabilization and takes on the role of an anti-corrosive as well as protection against heat, noise and humidity. Lightweight concrete elements have a low density implying a reduction in the dead load and, hence, less reinforcement and improvement of insulation properties.
- the system offers the possibility for the efficient completion of precast lightweight concrete elements or monolithic elements or combined. This construction system ensures quick, efficient and low cost assembly.

Subsequently, these foundations are fastened by foundation beams (9), which are either precast or monolithic. Then, the columns (6A) or (6B), either precast or monolithic, are placed into the foundations. After this, the roof valleys (7) are placed along the hall or a building. If this hall or building has two or more storeys then perpendicular (transversal) girder beams (3A, 3B or 3C) are placed and then the roof-ceiling TT slabs (1) or roof-ceiling plate (4) are placed over them. Subsequently, main roof beams (2) are placed. Finally, the roof TT slabs (1 ) or roof-ceiling plate (4) are placed followed by the facade panels (5) which are fixed to the foundation beams (9) and roof valley (7).
- One of the possible methods for the production of a lightweight body is lightweight concrete based on the aggregate made as expanded polystyrene. If the lightweight concrete is made of the light expanded polystyrene aggregate, then the density should be higher than 800 kg/m3 if elements are structural or exposed to any kind of fire load.
