The upgraded version of "steel house" appeared at Shandong Green Expo, and the future steel structure assembled residence will be like this.
Laigang Green Building Development Co., Ltd. is the traffic manager of Hall D. On the 13th, on the opening day of the 5th Shandong Green Expo, professional visitors and some citizens were constantly on the booth. What attracted them was a set of 1:1-scale fabricated steel structure residential buildings. This is a set of four rooms lined up, not only with intelligent living room, but also with assembled kitchen and assembled bathroom.
Of course, this is just the beginning. The staff turned on their mobile phones, and the curtains closed slowly by the living room window. "The smart home is also displayed here, which is what the steel structure assembled house can achieve in the future." Liu Zhigang said that Laigang Green Building Development Co., Ltd. is not only building fabricated steel residential buildings, but also cooperating with Haili, who has 2 years' experience in assembling fabricated steel residential buildings, to build smart and hard-bound fabricated steel residential buildings.
In addition to the smart home on the tall floor, the mystery of this living room is hidden beside the walls and doors. In order to show the construction process of the steel structure residence, the doors and beams of the room are exposed with steel structure. Walking to the outermost room, you can see the whole process of building a house with assembled steel structure.
"Look at the main structure of the house, that is, the beams and columns, which are made of special-shaped concrete columns made of hot-rolled steel in Laigang." Zhang Haibin, chief engineer of Laigang Green Building Development Company, introduced that the hot-rolled H-beam produced by Laigang can become L-shaped, T-shaped, I-shaped and other special-shaped columns, which can effectively solve the problem of steel columns protruding from the wall in existing steel residential buildings. This can save a part of the inner area of the sleeve. Zhang Haibin said that Laigang has the largest and most complete hot-rolled H-beam base in China, and can also realize direct customization of non-standard beams, with lower steel consumption, faster processing speed and more guaranteed quality.
with beams and columns, what should a steel structure residence use as a wall? The shear wall in the room, which is composed of steel plate, cold-formed steel keel, thermal insulation and sound insulation materials and cladding plates, has attracted many professional visitors. Such a shear wall can realize the integration of the lateral force resisting structure with the functions of building thermal insulation, sound insulation and decoration. Thermal insulation and sound insulation materials can be constructed in the recessed parts, and the cladding plate for decoration is fixed by the cold-formed steel keel, thus realizing the assembled decoration without painting the wall and pasting wallpaper.
the mystery lies not only in the interior of the house, but also in the outer wall of the house. On the outside of a window, you can see the exposed external wall for thermal insulation and decoration of integrated plate. This board is composed of insulation layer, decorative coating and so on. It is connected with the basic wall by adhesive anchor, which realizes the integration of energy saving, decoration and building. The overall effect is beautiful, safe, green and environmentally friendly.
how to cover the floor is also shown on site. This uses the detachable reinforced truss floor slab displayed on site. Truss reinforcement and bottom formwork are connected into a whole through connectors. During construction, the formwork is not needed on site, and the basement membrane can be reused after disassembly, which has a high degree of industrialization.
Liu Zhigang said that compared with the traditional houses with reinforced concrete as the main material, the prefabricated houses with steel structure can have a stronger seismic effect, and at the same time, the housing rate will be higher, that is, relatively speaking, the interior area will be larger. At the same time, it can better realize constant temperature and humidity, which can improve the comfort of living. More importantly, the fabricated steel structure residence represents a green and recyclable concept. "The steel used in steel-structured prefabricated houses is recyclable. Once the house is demolished many years later, these steels can be sold for a lot of money. Most of its construction process is carried out in factories, and on-site assembly can reduce environmental pollution such as dust. "
an assembled bathroom system and an assembled kitchen system were also displayed at the site. The bathroom uses the chassis of the factory, combined with quick-loading water supply and drainage, and the ceiling on the ground wall to form an organic whole. It is industrialized and ready to use, and can be integrated with waterproof and seamless design. This assembled bathroom also has the elements of smart home. Its mirror is a "magic mirror", which is equivalent to a smart device, and it can understand the weather and all kinds of information.
through integrated design, the assembled kitchen can be laid out reasonably and efficiently, meet the individual needs of users, and has the advantages of quick assembly, high quality, low cost and high space utilization. On-site kitchen cabinets and refrigerators have achieved an integrated design, and the cabinet door is the refrigerator door.
"The wall inside the assembled steel structure residence can be adjusted as required in the future. If you think the living room is too big, you can move this wall of the living room to a suitable position by professionals, and the corresponding bedroom can be bigger. " Liu Zhigang said that the construction cost of steel-structure prefabricated houses will generally increase by 1% compared with the traditional construction methods, but in the process of use, steel-structure prefabricated houses have more possibilities. If the prefabricated houses are renovated at the same time, they can be customized and transformed as needed in the future.
In 219, the General Office of the Ministry of Housing and Urban-Rural Development approved Shandong Province to carry out the pilot project of "steel structure assembled residence", and the pilot period was 3 years (219-221). The pilot area of Shandong Province includes 9 districts and cities including Jinan, Zaozhuang, Yantai, Weifang, Jining, Rizhao, Linyi, Liaocheng and Heze. In the pilot period of 22-221, our province will build more than 2 million square meters of new steel structure prefabricated houses, which is more than the total construction of steel structure prefabricated houses in 216-218.
This year, the Implementation Opinions on Promoting the Development of Steel Structure Assembled Dwellings jointly issued by the Housing and Construction Department of Shandong Province and other departments put forward that the steel structure assembled Dwellings should be fully renovated, and the decoration should be coordinated with the main structure and electromechanical equipment. Vigorously develop prefabricated decoration, advocate menu decoration, and encourage fine decoration and delivery. Popularize and apply advanced and applicable technologies such as green building materials, integrated kitchen, integrated toilet, integrated pipeline and drainage on the same floor to improve the green, healthy and comfortable quality of residential buildings.
