The south China sea has completed the country's first PI system assembly project

100% of the structural components are made of factory prefabricated cage molds and floor plates, which are transported to the construction site to build a house like building blocks. The main structure can be built one floor in three days, and the total construction period can be shortened by more than half...As a new technology of prefabricated architecture, how to subvert traditional architecture?Recently, the 2019 nanhai district new PI prefabricated system on-site inspection meeting was held in lishui town, where participants watched the first PI prefabricated project in China -- poly purple mountain mansion.

At the site of poly purple mountain project, three towers of the same size are also surrounded by green curtain. As the first prefabricated high-rise project structure of PI system, this project has been capped.There are three towers in this project, among which PI project is applied to the wall column and beam plate of 1 and 2 buildings, and 3 buildings adopt traditional cast-in-situ technology for comparison with PI technology.In the use of prefabricated components, the main PI wall, PI beam, bay window, laminated panels, prefabricated stairs.

Li zhongzhong, chief engineer, introduced that PI system developed a complete set of building industrialization technology based on hollow mold free self-balancing technology. The integrity and connection safety are completely consistent with the traditional cast-in-place structure, and it has the prominent characteristics of no building template and no construction waste.Most of the prefabricated parts are completed by factory automatic production lines and industrial robots. The weight is only 30% of the traditional prefabricated components. The transportation and installation are simple and fast.

Nanhai district has a large building volume and an active construction market. According to statistics, from 2016 to 2018, about 2,100 construction projects were reported in nanhai district, with a construction area of about 36.5 million square meters."Nowadays, the shortage of construction workers is becoming more and more prominent, and the demand for construction speed is getting faster and faster. The traditional construction mode has many problems such as construction waste, large pollution, long cycle and low safety. Therefore, it is in urgent need of reform.Nanhai district housing urban and rural construction and water conservancy bureau construction market supervision section chief zhou qunjian said.

At present, the central and local governments are vigorously advocating the development of prefabricated buildings. The foshan municipal government issued the implementation measures for promoting prefabricated buildings in foshan this year, requiring that the newly built prefabricated building area should account for more than 20% of the newly built building area by 2020, of which the government-invested prefabricated building area should account for more than 50%.By 2025, those ratios will rise to 35 per cent and 70 per cent, respectively.Zhou qun jian revealed that the south China sea also actively supports the development of prefabricated buildings. Currently, there are three prefabricated building factories and several prefabricated building projects under construction.
