  • New technology to build steel frame houses with only 2 employees

     

    Producing components forming steel frame houses on the same equipment line, helping to shorten construction time and manpower.

    Flexible production lines based on Australian technology

    Receiving designs, house sizes or architectural drawings, engineers only need to enter data into pre-programmed software. Software automatically draws 2D, 3D drawings, quotes, portfolio calculations and production data needed to build a complete steel building frame. The parameters calculated by the software are transferred to the processing machine. Components such as columns, rafters, purlins, U-shaped links, L ... are all created on the machine according to data associated with the design software and printed automatically. All accessories are then shipped from the factory to the construction site. The constructor only needs to see the printed code on the accessories, connecting them according to the design.

    This is a manufacturing process of pre-engineered steel building components and accessories, which are designed and completed by Viet Machinery and Steel Products Co., Ltd. under a national science and technology project and Technology transferred from Australia. Engineer Nguyen Tinh, the company's research and development department, said: "This approach helps to reduce 30% of the time of construction of pre-engineered steel buildings, civil construction stages with only 2 employees. is taking on the work of 7 people doing it the traditional way. "
     


    The expert team of the Ministry of Science and Technology is checking the Sigma line in the industrial house structure production system.
     

    After three years of research, Viet Steel has successfully developed two product lines: LightShed (light steel structure structure production line for industrial houses) and Lightframe (for civil houses). Each model has its own software and machine.

    Engineer Kieu Huynh Son, project manager shared, the design of the entire machine from the original drawing of the Australian partner is complicated because each device requires more than 5,000 details. The team must test and adjust several times in order to succeed.

    Flexible production line of pre-engineered steel buildings structure is a project under the Program of Research, Training and Construction of High-tech Technical Infrastructure under the National Program of High Technology Development to 2020 of the Ministry of Science and Technology Study and Technology.

    Dr. Do Quoc Quang, a member of the Program Steering Committee, said that this technology has been implemented in Australia and many countries but not popular in Vietnam. Owning technology, domestic enterprises do not have to spend a lot of foreign currency to import equipment from abroad. In 2015, with the support of the Ministry, Viet Steel Company transferred the design of purlin machine from Australia, invested in researching and perfecting the design.

    Potential for Vietnam construction industry

    Dr. Quang said that the technology of building pre-engineered steel buildings in Vietnam is considered an advanced construction trend because of using economical materials, fast installation, environmentally friendly and economical. high. But previous technology was only suitable for large-scale projects like industrial workshops because each accessory is only made from a separate machine. Small constructions and civil houses are difficult to apply widely because they require too many details and produce little cost price. Success in creating flexible production lines opens up the potential for steel bar industry in the field of construction, civil steel building, steel buildings with special designs.

    For industrial steel buildings, Viet Steel Company has built a standard model system, model house, which can be customized in length - width - height according to design requirements. Residential houses vary in style depending on the creativity of the architect, so there is no common pattern. Pre-engineered steel building frame components are designed and manufactured separately, interlocking to form framed structures for walls, floors, and roofs, thus forming the house.
     


    Customers are checking the purlin line, preparing to export to Australia.
     

    The team implementing the project "Improving the design and manufacturing of flexible production lines of pre-engineered light steel buildings" of Viet Steel Company has successfully defended the project at the national acceptance report. science and technology, held at HCMC University of Technical Education. Dr. Dao Van Hiep, Chairman of the Board of Acceptance, highly appreciated the success of the production line of flexible prefabricated steel buildings, consistent with advanced construction trends.

    According to Dr. Do Quoc Quang, in addition to scientific value, it is worth noting that this product has a high ability of commercialization, accepted by the domestic and foreign markets right after its launch. Mr. Kieu Huynh Son said that the company has successfully exported 10 synchronous lines to partners from difficult markets such as Australia, Taiwan, Malaysia, Ivory Coast ... "The total value of the transfer to partners from more than 30 countries are estimated at 1.5 million USD. The company's revenue has also increased by 20% since the adoption of this new line, "Son confirmed.
