Storey additions in LSTK technology

Mansard floors, superstructures, rafter systems made of galvanized profiles of the "LS Profi" company solve the main task - ensuring the maximum exploitation of the under-roof space, taking into account reliability and durability. Structures made of light steel profiles will cope with this perfectly.

The addition of a floor allows:

- use the existing engineering infrastructure;
- get an additional area of ​​up to 40%;
- reduce the cost of construction compared to new construction.

Due to the light weight and features of LSTK technology, the superstructure can be built over almost any building. The key factor in the decision to add a structure is the technical condition and structural features of the object being added, based on this, the addition is carried out with or without strengthening the structures of the building being added.

Currently, light ones are most often used for superstructures thin-walled steel profiles from which the frame of the floors is created are built up The frame structure made of galvanized profile is sheathed on the outside moisture-resistant plywood, OSB board, etc., and inside - plasterboard or OSB plate. The space inside the frame is filled with mineral wool plates based on basalt fiber or extruded polystyrene, forming a kind of sandwich. To protect the insulation from getting wet, steam is used and waterproofing films. External decoration can be in the form of hinged facade or facade plaster. As practice shows, the specific gravity of such is low structures provides minimal costs and, as a rule, does not require reinforcement existing building structures. The frame made of light steel profiles withstands seismic loads up to 9 points, snow loads up to 320 kg/m2 and wind loads up to 85 kg/m2. Another advantage is the all-season nature of this construction technology and the ability to carry out installation without the use of lifting equipment, which is important in conditions of already existing buildings. Steel profiles are manufactured in factories conditions, according to the project, and it allows you to achieve high accuracy in parallel with the possibility of adaptation under individual project. Steel profiles are produced according to the project size with mounting holes. The frame is assembled on bolts or screws. At superstructure floors, inter-floor ceilings are erected using such light constructions, as well as the wall frame. When using light steel structural beams are C and Z-shaped galvanized steel profiles. A the load-bearing floor is either a steel sheet placed on the transverse omega profile or on a profiled steel sheet. They are laid on them as a base for the floor board materials, such as OSB board. In the inner space of the structure, between the parallel supporting beams, place sound insulation from mineral plates. The structure closes from below suspended ceiling.

Superstructures of additional floors in LSTK technology is reliable a solution for those who want to expand their workspace. Our company "LS Profi" engages in the design and production of galvanized steel structures profiles
