Common quality problems in the embedded link of steel structure

Problem 1: There is a deviation between the plane position of the anchor bolt and the elevation.
Problem 2: In the process of fixing the anchor bolts, improper welding operations lead to excessive heat input, which in turn damages the base metal of the bolts.
Problem 3: Insufficient protection measures for finished anchor bolts
In the process of fixing anchor bolts, if the finished product protection measures are not implemented effectively, the surface damage or deformation of the bolt may be caused and its performance may be affected.
Problem 4: There is a deviation in the flatness of the embedded parts of the steel plate
In the construction process, if the flatness of the embedded steel plate is not properly controlled, it will lead to an error in the connection between it and the anchor bolts, and then affect the overall stability of the structure.

Common quality problems in the installation of steel structures
In the process of steel structure installation, a variety of quality problems may be encountered, and the appearance of these problems will not only affect the progress of the project, but also pose a potential threat to the safety of the structure. Among them, the deviation of the flatness of the embedded parts of the steel plate is a problem that cannot be ignored. Due to the improper control of the flatness of the embedded parts of the steel plate, it often leads to the error of the connection between it and the anchor bolts, which affects the stability of the whole structure. Therefore, in the process of steel structure installation, we must attach great importance to and take effective measures to ensure that the flatness of the embedded parts of the steel plate meets the requirements.
Problem 1: In the process of steel structure installation, welding temporary code plates, lifeline columns, ladder hanging ears and cutting lifting lugs and other operations will sometimes cause damage to the base metal.
Problem 2: The connecting plate is not tight in the splicing process.
Problem 3: In the docking process between the steel column and the steel beam after correction, the wrong deviation is too large or the groove size is too small.
Problem 4: During the installation process, the random cutting of steel components often produces many defects at the incision.

Common problems when installing high-strength bolts
In the process of installing high-strength bolts, a series of quality problems may be encountered. The occurrence of these problems will not only affect the use of bolts, but also may pose a threat to the stability of the overall structure. Therefore, during the installation process, we must strictly control every link to ensure that the high-strength bolts can be installed correctly and firmly in the intended position.
Problem 1: Storage of high-strength bolts
Before installing high-strength bolts, their storage is crucial. If the bolts are not properly stored, their quality may be compromised, which in turn will affect the installation effect. Therefore, we need to ensure that the bolt is protected from moisture, contamination or physical damage during storage to guarantee its performance and safety during use.
Problem 2: The dual role of high-strength bolts and installation bolts
In many engineering applications, high-strength bolts are not only used to join structures, but are also often used as mounting bolts. This dual role makes high-strength bolts play a crucial role in the installation process. However, this also places higher demands on the quality and performance of bolts to ensure that they can safely and efficiently perform their connection and installation functions.
Problem 3: The phenomenon of leakage of high-strength bolt threads and its impact
During the installation process, the problem of leakage of high-strength bolt threads is sometimes encountered, that is, the thread connection part is not completely engaged or loose. This phenomenon not only affects the connection effect of bolts, but also may cause safety hazards. Therefore, corresponding measures need to be taken to solve this problem and ensure that high-strength bolts can play their joint role safely and reliably.
Problem 4: Improper use of the direction of the high-strength bolt nut and washer
When installing high-strength bolts, the orientation of the nut to washer is crucial. If the direction is used improperly, it will directly affect the connection effect and safety of the bolt. Therefore, it is essential to carefully check and install correctly to ensure that the high-strength bolts function correctly and safely.

Common problems in steel structure welding
In the process of steel structure welding, various quality problems are often encountered. The occurrence of these problems will not only affect the quality and efficiency of welding, but also may pose a threat to the safety of the overall structure. Therefore, understanding and mastering these common problems, and taking effective measures to prevent and solve them, is the key to ensuring the quality of steel structure welding.
Problem 1: Crack phenomenon

Cracks are a common quality problem in the welding process of steel structures. It can be caused by welding stress, uneven material properties, and other factors, posing a potential threat to the integrity and safety of the structure. Therefore, it is necessary to pay close attention to the crack phenomenon and take corresponding preventive and repair measures to ensure the quality of welding.
