Product Description

The connection of SO flange steel structure conforms to the principle of reliable, clear force transmission, simple structure, convenient manufacturing and saving materials. The joint shall have sufficient strength and sufficient air direction suitable for the execution of the joint means. The connection method of the system structure can be divided into weld connection, rivet connection and bolt connection. Weld joint is the main joint of modern structure. Its advantages of simple structure, any form of components can be directly connected; Material economy, does not weaken the section, production and processing is convenient, can realize automatic operation, the connection is closed well, the structural stiffness of its disadvantage is in the weld near the heat-affected zone, the material of the whole phase of the change, resulting in the change of material, residual stress and residual deformation of the compressive member bearing capacity is reduced to crack structure, with crack day love, it is easy to expand to the whole, The problem of low temperature cold cell is more prominent. Because of the complex structure and the cost of steel and labor, rivets are seldom used now. But the foot nail connection type and system is better, the force transfer is called by, the care is easy to check, in some heavy and directly bear the dynamic load structure, sometimes still used. Zheng bolt connection Zheng bolt connection Kennedy bolt connection and degree bolt connection two kinds of general bolts are divided into, grade. Next and grade is bonded bolt, grade is leased bolt grade Bolt material energy grade is Grade or Grade. The number before the decimal point indicates that the tensile strength of the finished bolt is not less than; the number after the decimal point and the decimal point indicates that the cage strength ratio of the compulsory service point to the tensile strength ratio is or the material energy of the collar and grade bolt is slow; the tensile strength is not less than; the term strength ratio is
