With the popularity of light steel villas, more and more owners choose light steel villas instead of traditional brick villas. As the most worrying problem for the owner is how to control the quality of light steel villas, what are the key points that can be referenced? As a material supplier in the field of light steel villas, it has a strict control process for the construction of light steel villas, and there are the following key points.
First, the anchor bolts of light steel villas are embedded
The embedded quality of anchor bolts of light steel villas directly affects the installation quality of steel structures. Controlling the position, verticality, length and elevation of anchor bolts (groups) is of great significance to reduce the reaming and adjustment workload (and even avoid rework), and improve the quality of structural installation. The pre-embedding methods of the bolt include the direct embedding method and the reserved hole method. Before pouring the foundation concrete, the supervising engineer must strictly check the rationality and reliability of the construction method of buried bolts, as well as whether the measured indicators are within the scope of the specification.
Welding engineering is one of the important sub-projects of steel structure engineering manufacturing and installation. The supervising engineer must be engaged in welding preparation, welding process and finished product inspection, and do a good job in the quality control of welding engineering. There are many welding quality problems with manual welds. These problems include: welds, slag inclusions, porosity, lack of penetration, undercuts, misalignment, large deviation of weld size, no need for arc striking plates, welding deformation is not corrected, and spatter is not cleaned.
Second, the quality control of light steel villa welding engineering
High-strength bolt connection engineering is also one of the important sub-items of steel structure engineering, and it is also one of the weak links in the current construction quality
(1) Replace with bolts with lower strength;
(2) The treatment of high-strength bolted connection surface does not meet the requirements of the specification, including surface treatment, smooth and tight bonding, bolt hole quality, etc.;
(3) The tightening of high-strength bolts is not carried out according to the specification, such as one-time completion, there is no distinction between initial and final screwing, no torque wrench and subjective estimation.
In order to ensure the construction quality of high-strength bolt connection projects, the supervising engineer must have a high sense of responsibility to urge the construction unit to improve quality awareness, strengthen quality management, implement quality assurance measures, and actively take measures such as on-site supervision and parallel inspection. Only in this way can the construction quality of high-strength bolt connection projects be strictly controlled.
The rust removal and coating of steel structure engineering is a task that is easy to be ignored by steel structure construction units, and it is also a weak link in steel structure engineering construction.
