Prefabricated Cement Houses in Kaifeng County
There are projects and corporate activities related to prefabricated cement houses in Kaifeng County (now part of Weishi County). Here is a detailed introduction:
I. Related Enterprises and Project Situations Kaifeng Ningsheng Building Materials Co., Ltd. is carrying out a project to produce 1,000 prefabricated cement houses annually at No. 168, 500 meters south of the intersection at Qianzhangtie Village, Nancao Township, Weishi County. The total investment in this project reaches 5 million yuan, with 361,000 yuan invested in environmental protection measures. During the project implementation, environmental impacts such as exhaust gas, wastewater, noise, and solid waste have been fully considered, and corresponding preventive measures have been formulated, reflecting the project's emphasis on and standardization in environmental protection.
II. Construction Characteristics of Prefabricated Cement Houses Some companies claim that it takes only 4 hours to build a cement "prefabricated house" of about 200 square meters, with a warranty period of about 70 years. Its main body adopts a reinforced concrete structure. During construction, the mold size is adjusted according to the owner's needs, and then concrete is poured. High-strength mortar is used to fill the joints between each module to ensure the stability and integrity of the house structure. The charging standard is 300 yuan per square meter, and such "prefabricated houses" can be built up to 5 floors. The company is headquartered in Kaifeng City, Henan Province, with a wide range of business operations. Currently, it mainly undertakes residential projects and also undertakes dormitory and office building projects.
III. Expert Opinions and Applicable Conditions Experts state that there are no durability issues with the modules of such "prefabricated houses" themselves, but special attention must be paid to the design of the module joints. Such houses can be built in non-seismic zones, but the number of floors should not be too high. This is because the geological conditions in non-seismic zones are relatively stable, and the seismic resistance requirements for house structures are relatively low. However, an excessively high number of floors will increase the load and risks of the house, necessitating a comprehensive consideration of the structural safety and stability of the house.
