What is the difference between pitch and staggered pitch?
The staggered pitch is also known as alternate pitch or reeled pitch. The staggered pitch is defined as the distance measured along one rivet line from the centre of a rivet on it to the centre of the adjoining rivet on the adjacent parallel rivet line.
What are the different types of rivets according to the shape of their heads?
Following are the different types of Rivets:
- Snap head or cup head rivets.
- Pan head rivets.
- Conical head rivets.
- Countersunk head rivets.
- Flathead rivets.
- Buffercated head rivet.
- Hollow head rivets.
What is a rivet?
A rivet is a mechanical fastener composed of a head on one end and a cylindrical stem on another (called the tail) which has the appearance of a metal pin.
Why hammering is done in rivet?
Explanation: Holding red hot rivet at shop head end, hammering is made. It results into expansion of rivet to completely fill up the rivet hole and also into formation at driven head.
What are the different ways of arrangement of rivets?
Butt Joint.
- #1. Lap Joint.
- #2. Butt Joint.
- #1. Single Strap Butt Joint.
- #2. Double Strap Butt Joints.
- #1. Single Riveted Joint.
- #2. Double Riveted Joint.
- #1. Chain Type Riveted Joint.
- #2. Zig-Zag Type Riveted Joint.
Which rivet is used for heavy work?
Pan head rivet
Explanation: Pan head rivet is used for girders and heavy constructional work.
What is rivet spacing?
Rivet Spacing. Rivet spacing is measured between the centerlines of rivets in the same row. The minimum spacing between protruding head rivets shall not be less than 31⁄2 times the rivet diameter.
What is lug angle?
Lug angle is small piece of angle used to connect outstand legs of the members to the gusset plate. • The purpose of lug angle is to reduce the length of connection to the gusset plate and to reduce shear lag effect.
What is the difference between end and edge difference?
The end of a blanket is where the longest measurement (length) ends. The side of a blanket is where the shorter measurement (width) ends. The edge is the very narrow thickness of the material of which the blanket is made and/or the area close to the edge.
What is the importance of rivet spacing?
If rivets are placed too close to the edge the sheet may crack. If they are spaced too far the sheet is likely to turn up at the edges. It is good practice to lay out the rivets a little further from the edge so that the rivet holes can be oversized without violating the edge distance minimums.
What is meant by shear lag?
The non-uniform stress distribution that occurs in a tension member adjacent to a connection, in which all elements of the cross section are not directly connected, is commonly referred to as the shear lag effect.
What is staggered pitch of rivet?
The staggered pitch is also known as alternate pitch or reeled pitch. The staggered pitch is defined as the distance measured along one rivet line from the centre of a rivet on it to the centre of the adjoining rivet on the adjacent parallel rivet line. One or both the legs of an angle section may have double rivet lines.
A rivet is a permanent mechanical fastener consisting of a head at one end and a cylindrical stem at the other end (called the tail) which has the appearance of a metal pin. Rivets are used to join large structural members, small electronic assemblies, and just about any manner of part falling between these extremes.
Why is the process of riveting an inexpensive method?
The process of riveting is an inexpensive method. One of the reasons is the production of cheap. There is no compulsion of ferrous or non-ferrous materials both the metals can be joined with the process of riveting. Apart from metals it can also be used for the non-metals like wood, plastic, asbestos sheet etc.
