Nong'an Prefabricated Cement Houses

There are projects related to prefabricated cement houses in Nong'an, but traditional rural cement prefabricated panel houses have many problems, although cement 'prefabricated houses' also have certain advantages.

I. Overview of the Prefabricated Component Project in Nong'an There was once a PC prefabricated component project in the Changchun Nong'an Economic Development Zone, invested and constructed by Jilin Changfa New Urban Industry Co., Ltd., with a total investment of approximately 500 million yuan. The construction includes supporting buildings such as factory buildings and warehouses, and the purchase of various equipment. It is expected that after being put into production, it can achieve an annual output of 150,000 m³ of residential PC prefabricated components, including prefabricated wall panels, composite panels (prefabricated floor slabs), prefabricated stairs, prefabricated balconies, prefabricated columns, and prefabricated beams, meeting the construction needs of 600,000 square meters.

II. Problems with Traditional Rural Cement Prefabricated Panel Houses

1. High safety risks: These houses pose serious safety hazards, and even minor earthquakes can cause collapse. The quality of prefabricated cement panels on the market varies greatly, with a majority being inferior products, having a short service life, and potentially causing collapse accidents and casualties.
2. Poor sound insulation: Their sound insulation ability is extremely poor. Due to insufficient thickness and a structure that easily transmits sound, residents are easily disturbed by external noise, affecting their quality of life.
3. Serious water leakage problems: There are gaps in the panel joints, allowing rainwater to easily seep in and corrode the steel bars, not only affecting the structural safety of the house but also reducing its service life.
4. Limited spatial layout: The spatial layout of prefabricated cement houses is limited in terms of personalization, making it difficult to meet the diverse needs of different residents.
5. Poor wall performance: The walls have poor sound insulation and thermal insulation, are thin, and require separate thermal insulation treatment in cold regions. The connection and fixation are poor, posing risks for buildings from low floors to three floors or above, and cracks are prone to appear at the assembly points.

III. Advantages of Cement 'Prefabricated Houses' They adopt modern prefabrication technology, with the main components of the house produced in advance in the factory and then transported to the site for assembly. The cost is much lower than that of traditional brick-and-mortar houses, with a cost of only over 300 yuan per square meter. The construction speed is extremely fast, and a villa can be built in as fast as four hours with the cooperation of a few workers, making it suitable for scenarios with high requirements for cost and construction speed.
