Jinan Prefabricated Assembled House

Jinan's prefabricated assembled houses have developed rapidly, demonstrating outstanding performance in terms of applications, construction methods, advantages, industrial scale, and rural market applications.

Wide Applications: Jinan's prefabricated assembled houses are used in a variety of scenarios, including industrial plants, schools, hospitals, and large parking buildings. For example, the No.1 and No.2 warehouses of the China North Consumer Goods (Jinan) Distribution Center were constructed using prefabricated methods, accounting for 52.16% of the total building area. The parking building project at Jinan Sunac Cultural Tourism City significantly shortened its construction period through prefabricated construction.

Construction Methods: The main components are prefabricated in factories and then transported to the construction site for assembly using reliable connection methods. Taking steel-structured prefabricated buildings as an example, steel components are prefabricated in factories and then transported to the site for combination through welding, bolting, or riveting, forming the basic structure of the house. This model of "factory production + on-site assembly" achieves a combination of industrialization and standardization in construction.

Advantages:

• Energy Efficiency and Carbon Reduction: Energy-saving building materials are used, such as rock wool sandwich panels for warehouse exterior walls. When the outdoor temperature drops to as low as -10°C, the indoor temperature can still be maintained above 0°C, reducing the usage time of electric tracing equipment and lowering energy consumption.
• Fast Construction Speed: Compared to traditional concrete buildings, the construction speed is increased by about 30%, significantly shortening the construction period. For example, the steel structure intelligent manufacturing production line can customize steel components, and the interspersed construction method enables "building houses like assembling blocks." The construction period of the parking building project at Jinan Sunac Cultural Tourism City was shortened by more than two-thirds compared to traditional methods.
• High Safety: Steel has high strength and elastic modulus, with uniform material properties, resulting in better plasticity and toughness of the steel structure, and significantly superior seismic performance compared to traditional buildings.
• Cost Savings: The cost of house construction is 40% lower than that of traditional house building, demonstrating significant economic advantages.

Industrial Scale: Since the "14th Five-Year Plan" period, the newly started prefabricated building area in Jinan has exceeded 10 million square meters for three consecutive years, accounting for more than half of the newly built buildings. The city has 10 national-level prefabricated building industrial bases and 29 provincial-level industrial bases, ranking first in Shandong Province in terms of quantity, with a significant industrial clustering effect.

Rural Market Applications: Prefabricated steel-structured rural houses have attracted attention due to their environmentally friendly, fast, and detachable characteristics. For example, Hebei Zhuanzhu Technology Co., Ltd. launched the "100,000 Yuan Rural Villa" project, which features a short construction period, environmentally friendly materials, high structural strength, good seismic performance, and flexibility in disassembly. The cost of 100,000 yuan covers the main structure of the house to simple interior decoration, meeting the dual needs of rural families for comfort and economy.
