Green assembled school sees results

Qingdao Huangdao District First Kindergarten Project

The first kindergarten in Huangdao District was established in 1990 and is the top ten kindergarten in Shandong Province. It was built in M steel in-situ system and was completed in 2015. The project covers an area of 11,858 square meters and the construction area is more than 8,000 square meters. This project is the largest steel structure school building in China with the largest single area.

Jinshuihe School, Gangcheng District, Jinan City

The steel structure, wallboard and floor slab of the project are all produced in the workshop, which reduces the on-site construction intensity, saves the masonry and plastering process, greatly shortens the overall construction period, and has the advantages of green, environmental protection and energy saving. The smooth progress of the project will play a good role in demonstrating the development of public buildings.

China-Pakse Friendship School Butuka Academy

The newly built Butuka Academy covers an area of about 55,000 square meters. It has 10 classes in kindergartens, 26 classes in primary schools and 16 classes in secondary schools. It can accommodate about 3,000 students. The project uses industrialized construction to create a prefabricated steel structure green building. The assembled building structure concept improves the building integration rate and improves work efficiency by more than 50%; reduces construction pollution, reduces wet work by 80%, reduces construction waste by more than 50%; increases building comfort and increases building space More than 10%, the successful implementation of the green assembly structure system can bring reference.

Why choose assembled steel structure

Future development model

Recently, the CCTV news channel reported that the current architectural model promoted by China’s construction industry is called assembly-style architecture. In the next ten years, the proportion of China’s fabricated buildings will reach 30% in new buildings.

Give children more protection

Green, no harmful substances

The steel structure house is a construction method that replaces the wooden skeleton of the traditional wooden house with the M steel skeleton. The material used is 100% steel, and the parts are connected by screws and nails without using any welding and adhesive. Therefore, there is no need to worry about the harm caused to the human body due to the use of chemicals in the construction process. In addition, the construction site will not have a lot of dust and noise and other pollution to the surrounding environment.

Good safety performance

The steel structure is light in weight and its structure is only one-fifth the weight of the traditional brick-concrete structure, which greatly reduces the load on the earthquake and has high safety. In addition, the imported high-strength screws and bolts are used to connect the fixed frame and the frame, and the installation is scientific and quick. At the same time, the structural calculation is made for each building at the time of design, and the foundation and the overall structure of the building are designed based on the structural calculation. Structural calculations are the result of trials and practices in the United States and Japan, with patented technology rights and nationally recognized certificates.

Fire prevention, pest control

According to different design, the fire resistance time can reach 1 to 4 hours. The steel is non-combustible material and protected by deep galvanizing. It can prevent corrosion and termites, and can automatically repair the damage of the coating.

Anti-seismic and anti-storm, strong insulation

It can withstand 9° rare earthquakes and is suitable for areas with seismic intensity above VIII. The thermal insulation system has excellent performance and can save up to 70% energy compared with ordinary brick-concrete buildings.

Light steel structure houses use external insulation methods.

The method utilizes the unique properties of the steel structure, and the skeleton is tightly covered from the outside with a thin plastic heat-insulating moisture-proof material, and then the heat insulating material is provided, and an air layer is provided outside the heat insulating material, and the air layer is externally based on the customer. For exterior walls, various materials can be used for various exterior wall treatments. The external heat insulation method does not need to be insulated inside the skeleton, and the interior can be directly treated as an interior wall.

n Japan, insulation materials and fireproof materials are integrated, so the material requirements are extremely high. The thermal insulation performance of the steel structure utilizes the principle of external heat insulation. The air layer is connected to the roof in the wall body to ensure the poor conductor of heat. The principle is similar to the thermos bottle.

Therefore, on the basis of not increasing the construction cost, the excellent energy-saving and heat-insulating effect is achieved through the treatment of the building structure, and the disadvantages such as moisture, insects and the like caused by condensation are overcome, so the heat insulation method has been rapidly Replace the internal insulation method. Thereby ensuring the characteristics of the steel structure in winter and cool in summer. When the outdoor temperature is 0 degrees, the indoor temperature can still be maintained at 17.2 degrees. The indoor air temperature is adjusted to be warm in winter and cool in summer.

Design is very flexible

A wide range of material sizes and thicknesses provide a great space for designers to consider cost-effective designs or efficiency considerations.

There is still a long way to go in steel-framed buildings. In recent years, both the Ministry of Housing and the Ministry of Construction and the State Council have proposed to build buildings. It is undoubted that such buildings are changing people’s lives. The requirement of green development is the need to realize the modernization of buildings, and it is the only way for the transformation and upgrading of modern buildings in China.
