Visit the first assembled public rental housing project in Ji'nan with identity quality traceability
reporter Gu Qing
with the tower crane slowly hoisting the first block of building 3 wall board, located in the road and Hong Kong Kowloon Road intersection north of the new park public rental project formally entered the "assembly" construction stage. Reporters on the spot found that 6 buildings in this project have adopted "assembly style" construction, each building has more than 60% components to achieve industrial prefabrication. Each component has been implanted with electronic chips before leaving the factory. In the future, in the process of living, the component can pass the electronic "ID card". It goes back directly to the source.
> 60% components to achieve factory prefabrication
3 p.m. yesterday afternoon, reporters came to Hong Kong new garden public rental site. The construction site was like a large "building block" warehouse, arranged neatly with various components. On the floor of Building No. 3 building, the tower crane grabbed the floor of the floor to be half empty. Reporters saw that a block of pre cast wall panels was slowly placed in the set position, and soon one floor was half loaded.
the site staff told reporters that this is the way to build the industry. In the factory, the walls, staircases, windows, and the construction site can be put out. As a result of the staircase, air conditioning board, balcony board, wallboard and so on, more than 60% components have realized the industrialization prefabrication. Therefore, the use of foot and hand support is nearly 90% less than that of traditional housing construction, and the protection net is almost not used. The components are uniformly manufactured by steel dies in factories, and their surface smoothness and internal quality are incomparable to traditional casting methods.
each component has a special "identity card"
the reporter saw in the construction site, each of the prefabricated components has a two-dimensional code label, and the site staff told the reporter that this is the "identity card" of the component.
it is introduced that in these industrial precast components, there is an electronic chip similar to IC card. Although it is deeply "buried" into the component, the information of the number, name, qualification certificate and installation position can be displayed as long as the special scanning equipment is used. "This is equivalent to each component has exclusive" identity card ", its processing information in the factory, installation location can be clearly scanned. If there is any problem in the future housing process, it can be traced back to the source, so that it can facilitate maintenance and repair later.
"assembled" houses are not safe to worry about the safety of
"assembled" houses? A on-site technician told reporters that the assembly room was not as simple as some people imagined. Such as the external wall, staircase, corridor and other components in the production of the pre embedded steel bars, assembly of these steel bars and beams, columns of steel bite together, at the same time concrete pouring, so that they are firmly integrated, no security concerns.
in addition, reporters also learned that "assembly" houses had fewer defects. Because the outer wall of the assembly room is a whole, the window is also embedded, there is no gap, the traditional building elevator shaft perpendicularity is easy to deviate, the wall is easy to be empty, the window is easy to leak water and other small problems can be effectively eliminated.
