Advantages of making bolted steel frame

The advantages of making bolted steel frame compared to other skeletons are:

Execution speed:

The execution speed of structures with bolted joints is higher and fully tangible than welded joints, and the construction time of bolted structures is less than structures with welded joints, and due to the high duration of our country's projects, this The type of structures is suggested to reduce construction time.

Installation speed:

In this type of structures, due to the complete elimination of welding at the installation site, it is limited only by placing parts and tightening a number of bolts, which causes a significant increase in installation speed and installation errors are minimized.

Construction quality:

The quality of construction of the structure with the facilities available in the factory and according to the designed plans and under the supervision of the quality control unit is not comparable with welded structures that are built at the installation site.

Material’s discard:

Usually in hand calculations, the calculator is closed in selecting special sections of the beam and has to reach the desired section by adding sheets and welding, while in bolt and nut construction, it is possible to add lighter sections with more resistance, which use sheets. Minimizes hardware in the construction of cast sections.

Structure safety and stability:

Both theoretically and practically, it has been proven that bolted buildings are more resistant to earthquakes and lateral forces due to their better quality.

lower cost :

Execution of a bolted building can economically impose a lower cost on the owner, but this does not mean that two structures with exactly the same sections are less expensive bolted structures, but due to the open hand of the designer. In optimizing and constructing sections with lower weight, it is easily possible for the designer to reduce the weight of the structure.

Fire resistance:

At high temperatures, bolted joints are usually more resistant to heat and the structure is much less likely to be damaged than welded joints.

No need for workspace:

Usually in cities, due to the lack of suitable location and place to build, most contractors have suffered a lot, which by using this type of structures, has provided the ability to run in the busiest and smallest situations.

Global usage:

In all American and European countries, all structures are executed in the form of bolts and nuts, except in very insignificant structures where the joints are welded, which is one of the important reasons for using this type of structures in these countries, its better performance and ,most of those countries have experience in the construction of steel structures.

Structural corrosion:

In bolted and nut structures, before painting, the parts are de-rusted by sandblasting and wire brushing devices under the supervision of a quality control unit, which is not performed in welded structures, and also in welded structures instead of zinc-rich paint in Bolts and nuts are used, stainless steel is used, which causes rapid corrosion of the structure.

Possibility to use in accident management:

Due to the possibility of moving such structures, it is possible to move and install it in crisis areas such as floods and earthquakes.
