Steel joints

 GALVANIC ACTION:

when two metals are in contact, the one that is high in the galvanic series will become the anode and will corrode. The current flows from the positive high end of the table to the negative low end of the table

CO-EFFICIENT OF THERMAL EXPANSION:

The changes in temperature causes expansion and Contraction, these changes are quantified by co- efficient Specific gravity Density of the substance Density of water Tensile yield  the graphical representation of steel under pressure from . Deformation zone to failure or breakage of steel.  

OIL CANNING:

Visible waviness in the flat areas of metal roofing and metal wall panels. 


JOINTS:


BOLTS:

  • a bolted joint is a combination of a fastener and a nut. A long bolt with a nut, for example, is classified as a bolted joint.

  •  The combination of the bolt and nut is known as a bolted joint.




RIVET:

  • A connection between two members which are riveted together.

  • the permanent joining of parts by means of rivets; used mainly for fastening sheet and shaped rolled metal. Riveting may be used in lap, abutment, and double-coverplate joints.





PIN JOINT:

  • A pin joint is a connection between two objects that allows only relative rotation about a single axis.

  • A pin joint is a type of kinematic pair, an idealized description of the motion constraints within a machine, which allows motion analysis.

Steel Erection, Fabrication and Hybrid construction -Blog 16

Image
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...

BLOG- 8                                     STEEL , ALLOYS AND THEIR COMPARISON                                                               STEEL AND ALLOYS                                               An alloy is a blend consisting of metal and other elements. 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. Definition ALLOY :      A homogeneous mixture of a metal with other types of elements                       ...
