LSF Structure

What is the structure of LSF? LSF are actually prefabricated or modular systems made of thin wall steel sections (LGS). These steel sections are actually thin steel sheets with galvanized coatings. These sheets are rolled using special machines and roll making method and are produced as light profiles in different dimensions. These prefab steel structures are mainly executed dry and using complex connections.

Application of LSF Structure (LSF)

Multi-unit residential buildings up to 5 floors
Sports and educational complexes
Factories and industrial workshops
Construction of mezzanine in spaces with high height
Adding floors on the roof of the building
Construction of residential settlements when necessary in The minimum possible time
in general, the construction of any structure and building that faces floor restrictions.

The components of the LSF structures (LSF)

In general, a panel of this structure includes several main parts as follows:

Cold-rolled steel sheets to provide the structure
Gypsum boards as inner covering
Heat and sound insulation layer

How to build LSF structures (LSF)

To implement this building structure, it is necessary to act according to other normal buildings and all the necessary arrangements Among other things, he made soil tests and architectural plans. In short, the implementation of the LSF structure can be summarized in the following steps.

Pi and Foundation
The skeleton of the structure including wall and ceiling
internal and external coverings of the structure
electrical and mechanical facilities
window door

Foundation and foundation

To install the walls, a foundation with a depth of approximately 50 cm is implemented. After finishing the foundation process, the anchor bolts are placed inside the foundation at predetermined distances so that the walls can be stabilized using them.

Installation of walls

After the implementation of the foundation, it is time to install the walls. As mentioned above, anchor bolts are used to install the walls and keep them stable, which were placed inside the foundation. The walls in these light structures are responsible for bearing the lateral and gravity loads.

The load-bearing walls are installed using some kind of temporary restraints in the designated place. In LSF buildings, lateral load-bearing openings or load-bearing walls are used for the lateral load-bearing of the structure. At this stage, the anchor rods installed in the foundation are connected to the load-bearing walls. The installation of non-load-bearing walls, which will not affect the structure, is mainly done after installation.

Running the ceiling

In the implementation of the roof in LSF structures, they usually follow different methods and styles. Roof trusses and flat beam system are the most used methods of roof implementation. Roof covering is mainly done in dry form or in situ concrete. The construction of these structures mainly consists of cold-rolled metal beams, the distance of which is determined according to the bearing capacity of the member and the dimensions of the roof covering parts.

Interior and exterior coatings

All kinds of traditional or modern materials can be used in external coverings or facades. External coatings can be applied wet and mortar or dry. Various materials can also be used to cover the walls in the interior spaces as well as wall paper, paint, wall covering, various types of tiles and plaster. In the floor covering, you can use all kinds of parquet, carpet and flooring. Insulation of internal and external walls is mainly done using 5 cm thick polystyrene sheets.

Implementation of electrical and mechanical installations

Mechanical facilities used in LSF structures include piping and air conditioning system. The piping of these structures mainly uses super pipe and compressed PVC pipes, which have much higher resistance and flexibility than metal and cast iron pipes. The installation and implementation of the ventilation system is also done based on the opinion and taste of the employer.

Electrical facilities also include wiring, all kinds of switches and sockets, electrical panels and telephone and TV lines. The implementation and installation of electrical facilities in these types of structures is done easily as much as possible due to their pre-fabrication and the presence of empty space between the walls.
