Characteristics of flange bolts for connection

The flange bolt connection has the advantages of simple and fast installation, being able to be installed and disassembled, high pressure bearing, good stress performance, safety and reliability. Its characteristics are:

(1) Improve the structural stress situation. The force transmitted by the friction type high-strength bolt connection relies on the friction force on the surface of the steel plate, which improves the large area of force transmission and stress concentration, and improves the fatigue strength of the components.

(2) The amount of bolts used is small. High strength bolts have a large load-bearing capacity, with a diameter of d=22 mm of 40 boron steel. The load-bearing capacity of flange bolts is: while the shear strength of a 23 mm diameter ordinary rivet is: it can be seen that the load-bearing capacity of flange bolts is about 18% higher than that of rivets. Under the same force, the number of high-strength bolts is relatively less than the number of rivets.

(3) Accelerate construction progress. The construction of high-strength flange bolts is simple, and for a worker who is not familiar with high-strength flange bolt construction, as long as they receive simple training, they can take up the job and operate.

(4) It is not easy to loosen during the transportation of steel structures and reduces maintenance workload during use. If it becomes loose, it can be replaced individually without affecting the connection of the surrounding bolts.

(5) The construction labor conditions are good, and the bolt holes can be formed in one go in the factory, saving the process of secondary hole expansion.

In summary, the above information provides a detailed description of the product characteristics that flange bolts possess when applied
