At this stage, the design of the plant is generally built with steel structure, which reduces the construction period and effectively saves the cost of the enterprise. Steel structure has many advantages in the process of use, but there are also certain defects. If the hidden dangers in the steel structure workshop cannot be remedied in time, it will cause damage to personnel and equipment. withThe continuous expansion of the factory, the increase of the load of the plant, and the slow aging of the steel structure, the reinforcement of the steel structure of the plant is necessary
At present, there are many connection methods of components in the steel structure workshop, and there are more common onesRiveting, welding, high-strength bolting and welding with high-strength bolt hybrid connectionThe stiffness of the riveted connection is the smallest (except for the ordinary bolt connection), the welded connection has large rigidity and good integrity, and the high-strength bolt connection is in between. The selection of reinforcement connection mode must meet the requirements of not destroying the function of the original structure and participating in the work.
In the reinforcement of the same stressed part, it is not advisable to use the reinforcement connection with a large difference in stiffness, such as the mixed connection method of weld and rivet or ordinary bolt common force, except when only considering the connection with greater stiffness (such as weld) to bear all the force. If there is a basis, a hybrid connection with a weld and a friction type high-strength bolt can be used. If the gap between the steel structures reinforced by the plant is small, the overall structure can be reinforced by welding, and if the welding method cannot be used, friction high-strength bolts can be used to connect.
All in all, the reinforcement work of the steel structure workshop needs to be carried out according to local conditions, and the existing structure needs to be effectively used for reinforcement, rather than demolishing the original building, resulting in an extension of the construction period. When reinforcing the plant, it is necessary to invite professional personnel to participate in the design and formulate the corresponding work plan to help the enterprise extend the service life of the plant, improve the stability of the overall building, and improve the strength of the enterprise itself.
