Jun. 18, 2019

Many customers think that the current buildings are all reinforced concrete structures, and the stability is very strong, so there is no need for reinforcement. This is a big mistake. The building may be relatively stable when it is first put into use, but the building is a long-term use. The objects will naturally appear various diseases as the number of years of use increases. Why must the building be reinforced? In building reinforcement, you will find that there are some problems in the buildings that need to be reinforced. Reinforcement can increase the period of use of the building and increase the safety and reliability of the building. So what are the reasons for building reinforcement?

What are the reasons for building reinforcement?

1. Construction quality, decoration damage, excessive use, etc. There are many reasons for construction quality accidents. There are objective and subjective factors, mainly: the strength of materials or other technical indicators do not meet the requirements, such as low concrete strength grade, unqualified steel and steel plates, etc. There are mistakes during construction. The steel bars are leaked, placed less, overlapped, anchored, etc.; the node construction measures are improperly handled, and the newly connected hinges and hinged joints are difficult to handle; the size or position of the components is not equal.

2. The design has reached the end of its useful life, or the original structure cannot meet the requirements under the existing specifications. Today's buildings are designed to last for 50 years. When they reach 50 years or not, they need to be reinforced by structural identification. After the earthquake in Sichuan in 2008, new seismic codes were issued. If the existing buildings could not meet the existing specifications, seismic reinforcement would be required.
