Slimming steel bar? It means that normal steel bars are stretched before being used in building construction, in order to reduce the construction cost. These steel bars can't meet the national standards, and they are all processed from waste steel bars. How about these? Slimming steel bar? What are the quality problems?
It is impossible to guarantee the safety of the building, and the steel bar is elongated and thinned, which destroys the ductility of the steel bar and changes the steel bar. Crispy? Its performance has also undergone fundamental changes. If these steel bars are used in buildings, they will affect the quality of buildings, mainly in the seismic aspects of buildings.
Generally speaking, when a building is subjected to a huge external force such as an earthquake, normal steel bars will stretch with the deformation of the building, thus prolonging the collapse time of the building and striving for more escape time for people in the building. And then what? Slimming steel bar? When subjected to huge external force such as earthquake, it will suddenly break and cause the building to collapse instantly, making the residents in the building have no chance to escape, which is a huge safety hazard.
How to rectify this chaotic image of slimming steel bars? This problem has existed for a long time. A few years ago, some places issued a document demanding that the quality management of steel bars should ensure every pass, and the construction unit should strictly control the entry of steel bars. It is forbidden to use steel bars whose product quality does not meet the mandatory national standards, and the steel bars entering the construction site shall be inspected and accepted according to the procedures.
After the exposure of the 3 15 party, Jieyang, Guangdong investigated and dealt with the problem enterprises overnight, sealed up four places suspected of producing the problem steel, and seized about 5,600 tons of the suspected problem steel. We will continue to trace the direction of the problem steel bars, conduct a comprehensive investigation and excavation, and resolutely put an end to similar problems.
?
These? Slimming steel bar? If the investigation can be found out, the key is that the supervision department should do something. I hope this problem can really attract attention after exposure.
