BLOG -16- STEEL ERECTION AND HYBRID CONSTRUCTION

STEEL ERECTION:

The erection of structural steelwork consists of the assembly of steel components into a frame on site. The processes involve lifting and placing components into position, then connecting them together. Generally this is achieved through bolting but sometimes site welding is used.


It is assembled on site, because of their size, and this operation often requires a second (usually truck mounted) crane. Set-up, and similarly dismantling, is therefore expensive. They also have a relatively slow lifting rate, which means they are only used when site conditions preclude an alternative. 


ERECTION TECHNIQUES:


 • MOBILE CRANE

 • TOWER CRANE


MOBILE CRANE :

Mobile Elevating Work Platforms) are predominantly used for the erection of structural steelwork for buildings and bridges

although other techniques are sometimes used for steel bridge construction.


TOWER CRANE :

It is assembled on site, because of their size, and this operation often requires a second (usually truck mounted) crane. Set-up, and similarly dismantling, is therefore expensive. They also have a relatively slow lifting rate, which means they are only used when site conditions preclude an alternative. 



ERECTION ISSUES:


MATERIALS :

 • Carrying Heavy tools

 • Handling Heavy suspended loads


TOOLS:

 • Many Tools req for connection

 • Use of fall protection Requirement


DESIGN:

 • Working with structural elements having irregualar shapes

 • Unstable loads when rigging


PROCESS:

 • Walking on narrow surfaces

 • Walkjng on irregualr surfaces

 • Moving at high elevations

 • Interaction with moving equipment



HYBRID CONSTRUCTION:


Hybrid buildings are becoming increasingly common because they make use of materials which are renewable, more eco-conscious materials, and because they’re often erected more quickly than buildings that exclusively rely on structural steel.


It seems like an improved version of mixed use building to solve problems related to mixed use such as land scarcity.


DESIGN TECHNQUE:


 • Hybrid building system construction is a building technique that uses both modular and prefabricated elements. 

 • This includes the high productivity involved in the construction of modules and the ease of transportation offered in a prefabricated or flat pack build, when transporting convenient sized panels to a range of sites.


ADVANTAGES OF HYBRID BUILDINGS:

Hybrid buildings offer optimal advantages  for those  reaching out for high quality and cost competitiveness, along with an ideal environmental life cycle assessment.

Steel Erection, Fabrication and Hybrid construction -Blog 16

This blog is about how the steel sections are transported to the site, the issues involved with transportation, erection and fabrication along with the onsite constrains. TRANSPORTATION: The steel sections have to transported from the manufacturing site to the fabrication site and this becomes a tough task due to their size. Often large pieces cannot be transported in a single part, they are split or divided and shipped as two separate pieces or even as one piece to avoid damage or scratches. Temporary connections are made on the pieces to avoid damage and to keep the parts in place during transportation.     These parts are not transported in normal vehicles but require long trail vehicles to fit their length and size which again becomes a difficult task to turn around the corners of the road and at junctions     FABRICATION & ON SITE CONSTRAINS: Fabrication of steel on sites which are along the main road or at the corner site is very hectic as there is very...

BLOG-16 FABRICATION, ERECTION AND HYBRID STRUCTURES

Image
  FABRICATION: The process of  steel fabrication  involves grinding, welding, cutting, bending, drilling, punching, burning or melting and other general crafting methods using various high-quality tools and CNC equipment. ERECTION LIFTING, POSITIONING AND PLACING OF STEEL MEMBERS IN A STRUCTURE  Once the member(s) are lifted and placed in the required place, with the help of temporary supports and equipment, they are fastened and fixed, depending on the nature of connection.  Erections may be achieved by two techniques such as MEWP(Mobile Elevating Work Platforms) by Mobile crane and Tower cranes. HYBRID STRUCTURES Hybrid structures are structures built with composite materials a combination of different materials with steel. A common  hybrid system  consists of hollow core slabs together with steel or cast-in-situ concrete frames                       EXAMPLE STEEL WITH TIMBER     I...

Alloys are generally made for achieving properties like greater strength or resistance to corrosion. Steel is an alloy of iron. It mainly consists of iron with some small amounts of carbon.
