The upgraded version of "Steel House" appeared in Shandong Green Expo, and the future steel structure assembled residence will be like this.

165438+ 10 month13-15, the 5th Shandong Green Building and New Technology Products Expo was held in Shandong International Convention and Exhibition Center. In Hall D of the exhibition, Laigang Green Building Development Co., Ltd. directly exhibited a set of prefabricated residential space with steel structure, which can be used for packing. In this house, visitors can not only see how the prefabricated steel structure residence was built, but also see how tall it will be in the future.

Laigang Green Building Development Co., Ltd. is the traffic manager of Hall D. On the opening day of the 5th Shandong Green Expo on June 5438+03, professional visitors and some citizens streamed in the booth. What attracted them was a set of prefabricated steel structure residence with the scale of 1: 1. This is a set of four rooms lined up, not only with smart living room, but also with assembled kitchen and bathroom.

Of course, this is just the beginning. The staff turned on their mobile phones, and the curtains at the living room window slowly closed. "Smart homes are also displayed here, which can be achieved by prefabricated houses with steel structures in the future." Liu Zhigang said that Laigang Green Building Development Co., Ltd. is not only building prefabricated steel residential buildings, but will also cooperate with Li Hai, who has 20 years of experience in assembling prefabricated steel residential buildings, to build smart hardcover prefabricated steel residential buildings.

In addition to high-rise smart homes, the mystery of this living room is hidden next to walls and doors. In order to show the construction process of steel structure residence, the doors and beams of the room are exposed in the steel structure. Walking to the outermost room, you can see the whole process of building a house with assembled steel structure.

"First look at the main structure of the house, that is, the beams and columns, which are all special-shaped concrete columns made of hot-rolled steel bars in Laigang." Zhang Haibin, chief engineer of Laigang Green Building Development Company, introduced that the hot-rolled H-beam produced by Laigang can be changed into L-shaped, T-shaped, I-shaped and other special-shaped columns, which can effectively solve the problem that steel columns protrude from the wall in existing steel structure houses. 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 it can also realize direct customization of non-standard beams, with lower steel consumption, faster processing speed and more guaranteed quality.

What is the wall of a steel residential building with beams and columns? The shear wall in the room is composed of steel plate, cold-formed steel keel, thermal insulation and sound insulation material and composite plate, which attracts many professional visitors. This kind of shear wall can realize the integration of lateral resistance structure and building thermal insulation, sound insulation and decoration functions. Thermal insulation and sound insulation materials can be constructed in the recessed part, and the decorative cladding plate is fixed with 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 exterior wall of the house. Outside a window, you can see the exposed external wall, an integrated board for insulation and decoration. This kind of board consists of insulation layer, decorative coating and so on. By bonding and anchoring with the foundation wall, the integration of energy saving, decoration and building is realized. The overall effect is beautiful, safe, green and environmentally friendly.

How to cover the floor is also a live demonstration. This uses the detachable steel truss floor displayed on site. The truss reinforcement and the bottom formwork are connected into a whole by connecting pieces. There is no need for formwork on site during construction, 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 yield will be higher, that is, relatively speaking, the internal area will be larger. At the same time, it can better realize constant temperature and humidity and improve the comfort of living. More importantly, the prefabricated steel structure residence represents a green and recyclable concept. "The steel used in steel structure mobile homes is recyclable. Once the house is demolished many years later, these steels can be sold for a lot of money. Most of its construction processes are carried out in factories, and on-site assembly can reduce environmental pollution such as dust. "

The assembled bathroom system and the assembled kitchen system were also displayed at the scene. The bathroom adopts the chassis of the factory, combined with quick-loading water supply and drainage, and the ceiling on the ground wall is integrated. It is industrialized, 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 an intelligent device that can understand the weather and all kinds of information.

Through integrated design, the assembled kitchen can be laid out reasonably and efficiently, meeting the individual needs of users, and has the advantages of fast 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.

"In the prefabricated steel structure residence, the walls in the suite can be adjusted according to future needs. If you think that the living room is too big, you can let professionals move this wall of the living room to a suitable position, and the corresponding bedroom can be bigger. " Liu Zhigang said that in the construction, the cost of steel structure trailer will generally increase by 10% compared with the traditional construction method. However, in the process of use, there are more possibilities for steel structure prefabricated houses. If the prefabricated houses are decorated at the same time, they can be customized according to the needs in the future.

In 20 19, 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", with a pilot period of 3 years (20 19-202 1). The pilot areas in Shandong Province include 9 districts and cities including Jinan, Zaozhuang, Yantai, Weifang, Jining, Rizhao, Linyi, Liaocheng and Heze. In the pilot year of 2020-202 1, our province will build more than 2 million square meters of prefabricated steel structure housing, which is more than the total construction of prefabricated steel structure housing in 20 16-20 18.

This year, the "Implementation Opinions on Promoting the Development of Steel Structure Assembled Residence" jointly issued by the Housing and Construction Department of Shandong Province proposed that the steel structure assembled residence should be fully renovated, and the decoration should be coordinated with the main structure and mechanical and electrical equipment. Vigorously develop prefabricated decoration, advocate menu decoration and encourage fine decoration delivery. Promote the application of advanced and applicable technologies such as green building materials, integrated kitchen, integrated toilet, integrated pipeline on the same floor, drainage, etc., and improve the green, healthy and comfortable quality of residential buildings.
