EFFICIENCY FROM THE SOLUTIONS TO STRUCTURE LARGE SECONDARY SCHOOL WORKS IN DAND OIL SIGNED TH1 UNDER THE EAST SOUTHERN TRAN DUY HUNG Urban Area (Cau Giay, Hanoi) (16/09/2020)

On the morning of September 5, 2020, the People’s Committee of Cau Giay District (Hanoi City) held a groundbreaking ceremony for the construction of the junior high school in the plot of land with the symbol TH1 in Southeast Tran Duy Hung Urban Area, Trung Hoa Ward ( Cau Giay District, Hanoi). The work is built on a plot of land with symbol TH1 in Southeast Tran Duy Hung urban area, in the central area of ​​Cau Giay district (Hanoi). With a total investment of up to 270 billion VND, the project is designed with 01 basement and 05 floating floors with 44 classrooms and full function rooms according to national standard school level 2. Modern architecture, in which efficiency has a big contribution from the solution of large aperture structure design, creates an almost non-repeatable feature in existing school buildings.

Construction design perspective

First of all, the structural design of the project is optimal in terms of aesthetics and use when applying the Consol beam system solution. For the space of corridors and stairs, to optimize the design to create aesthetics, the architectural plan has eliminated the maximum details, prioritizing the use of a large aperture structural solution to make the building “ fly ”more, as well as free up views from the corridors, the classroom system structure is designed to race 3m by the Consol 700mm high main girder system to create a clear space as well as layout. class blocks are located parallel to each other. The structure of the gable staircase blocks the design class racing 3m by the girder system from the top of the gable wall.

Along with that, the project also applies a high-tech steel girder system solution, including the bridge corridor system with an aperture of 14m. Corridor space connecting traffic of 2 classroom blocks is also combined by synchronous and efficient I600 steel girder system.

For classroom spaces, based on the application experience in a number of recently deployed school buildings, the design using a checkered-type interference sub-girder system allows optimal height as well as layout. decoration of lighting, ventilation, air-conditioning equipment for the building and especially to increase the aesthetics – comfort of the classroom space.

For multi-purpose house spaces and covered swimming pools, to achieve aesthetics, comfort and safety, the design solution uses a combination of 1.2m high beams with 200mm thick slabs, exceeding 16.8m spans. optimized for use with a variety of purposes at different times of the day.

With superior design and national standard level 2 facilities, THSC school at Lot TH1 – Southeast Tran Duy Hung Urban Area will be an outstanding architectural work in the heart of the area. modern city. The project is designed by Sunjin Vietnam Joint Venture Company, in which Engineer. Tran Thanh Tung – Head of Structure 1 is the chair of the structure.
