" THOUGHTS OF STEEL - STEEL CONNECTIONS"

 

   Hello guys!

 

   Today we discuss “Types of steel connections”. We are using connections as connecting two different steel or connecting the beam and column basis. We are going to see when?! Where?! How?! we can use these connections in structure and some detailed drawings of steel connections. “Riveted, Bolted and Welded” are the common three steel connections that we have seen in our regular life.

   Riveted connections are generally used in the older structure, it is more similar to bolted connections. The rivet is placed into the hole in the steel to join and support, the heat head of the rivet which helps to prevent the metal from coming out. There’s an advantage of the rivet is while dismantling of a rivet joint cause less damage when compared to a welded joint, it can be used for joining ferrous and non-ferrous metal too, it does have some ability to joint regardless of the location. There are some limitations and disadvantages too like rivet joints are high in cost, the hole may weak the steel, while construction typically does not makes the tight or leak-proof joint unless using a hot rivet. (1)

  Welded joints are construction basis joints and they also use on a factory basis too. There are advantages of welded joints are, it may happen easily with smooth finishes, need less skilled labor for joining. While welding more noise may create while constructions are one of the common problems in welded joints. (1)

   Bolted connections have some flexibility in assembling parts of the structure, it is quite easy to fix and remove the connection for reuse. Instead of braking the steel, removing it is a more sustainable way to reuse the steel. There’s an advantage of bolted connections, the working process has been easier and not more skilled labors, this connection needs lesser working area for constructions and storage. There are some disadvantages too, bolted connections are costlier like the riveted connections, due to the heavy vibrations bolts may loosen. (1)

  Okay well, we have seen the common joints and how does it work and benefits of it. Now let us discuss how these joints used in structure and where and all we can use it. These joints use for a various connecting purpose like (1)

        I.            Beam to column flange connections

      II.            Beam to beam web connections

   III.            Column to column splice connection

   IV.            Column bases at foundations

     V.            Bracing connections

 “Do we have types of connection ? yes we do” we have ‘n’ number of connections for connecting steel. We will discuss some of the connections

I.            Pinned connection

II.            Tie connection

III.            Tubular connections

IV.            Taper connection

V.            Custom casting

VI.            High strength connection etc… (1) (2)

  That’s all for today, We will continue our journey with a new experience, soon…!
