The main load-bearing structure of the high and low-rise cold-formed thin-walled steel prefabricated house system for living containers is composed of cold-formed thin-walled steel and structural panels to form a closely ribbed plate wall structure. This structure has good integrity and light self-weight, and can withstand earthquakes of magnitude 8 or above and hurricanes with wind speeds of up to 50 meters per second.
All the materials used in the industrialized production of the low-rise cold-formed thin-walled steel prefabricated villa house system (cold-formed high-frequency welded light thin-walled square tubes (rectangular tubes), triangular V-shaped connection components, structural panels, insulation and sound insulation materials) are industrialized products, greatly reducing the factors affecting the quality of components, and it is very easy to control the quality of components. The component size control has reached the millimeter level, providing a good foundation for the later decoration project. The industrialization of production has provided ample space for the large-scale and industrialized development of this building structure system.
In addition to the foundation being constructed in accordance with the traditional structural form (the amount of work for this foundation is also less than that of the traditional reinforced concrete foundation), the construction of container houses for living in Nanjing has fully realized factory prefabrication and on-site assembly construction. After the components are installed in place, they reach 100% strength immediately, with no construction technical intervals, which improves labor productivity. The components are precisely processed in accordance with the design drawings, and the on-site construction is completely dry operation, with a high level of civilized construction. The installation technique is easy to master. An ordinary worker can become proficient in installation operations after two days of training. The construction speed is fast, and the funds invested in real estate development can be recovered quickly. It only takes one to two weeks to complete the installation of the main structure of a 200-300 square meter house, and it only takes one month to reach the rough decoration standard.
