DEFINATION OF TURNBUCKLE

Two round tie rods subjected to tensile loading

These rods are connected by coupling

This is known as Turnbuckle

INSTRUCTIONS FOR USE straight or in-line pulling only. It should be paid to prevent overloading. 1. Tensioning : the forces on the turnbuckle must

not be such that any deformation occurs.2. Deformation : The tension should be decreased

immediately and deformed parts should be replaced.

The products are regularly inspected. Inspection should take place in accordance with

the safety standards given in the country of use like wear, misuse, overloading etc. with a consequence of deformation and alteration of the steel structure

DESIGN OF TURNBUCKLE

FUNCTION

Turnbuckles are most commonly used in applications which require a great deal of tension

they can range in mass from about ten grams for thin cable used in a garden fence, to thousands of kilograms for structural elements in buildings and suspension bridges

Turnbuckles are used for tensioning a ship’s rigging and lashings. This device is also known as a bottle screw in this context.

THEORY A turnbuckle, stretching screw or bottle

screw is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems.

It normally consists of two threaded eye bolts, 1. With a left hand thread 2. With a right hand thread

A metal coupling device consisting of an oblong piece internally threaded at both ends into which the corresponding sections of two threaded rods are screwed in order to form a unit that can be adjusted for tension or length.
