The high-strength Stay Wire Assembly Fititngs connection relies on the friction between the contact surfaces of the connectors to prevent them from sliding. In order to make the contact surfaces have sufficient friction, it is necessary to increase the clamping force of the component and increase the contact surface of the component. Coefficient of friction. The clamping force between the components is achieved by applying pre-tension to the Stay Wire Assembly Fititngs, so the Stay Wire Assembly Fititngs must be made of high-strength steel, which is the reason for the high-strength Stay Wire Assembly Fititngs connection.
In the high-strength Stay Wire Assembly Fititngs connection, the friction coefficient has a great influence on the bearing capacity. Tests show that the friction coefficient is mainly affected by the form of the contact surface and the material of the component. In order to increase the friction coefficient of the contact surface, methods such as sandblasting and wire brush cleaning are often used to treat the contact surface of the components within the connection range.
There are actually two types of high-strength Stay Wire Assembly Fititngs: friction type and pressure-bearing type.
The criterion of friction-type high-strength Stay Wire Assembly Fititngs for bearing shear force is that the shear force caused by the design load does not exceed the friction force.
The pressure-bearing high-strength Stay Wire Assembly Fititngs is based on the design criteria that the shaft is not cut or the plate is not crushed.
