Why is it necessary to add layers to the steel structure

Steel structure adding layer technology is a new type of reinforcement and transformation, which is being implemented step by step. In terms of technology, economy and safety, it has obvious advantages over concrete buildings, but its current use in the world is not very common, and the design is not perfect.

Present situation of research on adding layers to steel structures. The construction of existing buildings in China has begun early. In order to adapt to the rapid development of building structure reinforcement, transformation and steel structure addition projects, and better complete the addition and transformation of old buildings, China has successively established academic groups such as building addition and transformation technology. Research Committee and enhanced technical standards committee. Form an active academic discussion and experience exchange environment for steel structure addition and transformation projects.

Used when adding layers to the original structure. Generally, this layer adding conversion technology is also called outer frame layer adding structure. The outer frame plus layer structure is mainly divided into several categories, which are separate and integral. The outer frame and storey structure are completely separated from the old house; The latter correspondingly means that the outer frame is connected with the old house structure as a whole.

In the construction industry, many companies may lack services. Many customers may encounter engineering problems and cannot find solutions. They often feel disappointed. For this after-sales problem, you need to find a professional merchant to buy, so that any problems in the future can be well solved.
