The construction industry accelerates the transformation to green intelligence
2022-12-27
At the site of Sun Hotel · Shuijingjing Square Project in Nanxun District, Huzhou City, Zhejiang Province, the building is the largest spherical reticulated shell structure in China, and will become the largest spherical building in the world after completion. The Chinese Character Park is located on the east and west sides of the Chinese Character Museum in Anyang City, Henan Province. It combines ecology, nature and humanity to form six parks. Looking back to 2022, the construction industry has withstood the test of epidemic situation and other aspects. With the change of the market environment, the transformation of the construction industry is imminent. The construction industry, led by scientific and technological innovation, promotes the transformation and upgrading of the industry to industrialization, green and intelligent. Fabricated buildings promote production efficiency. In recent years, China has vigorously developed the industrialization of new buildings represented by prefabricated buildings to promote the optimization and upgrading of "built in China". A number of independent innovative software have risen, equipment levels have been constantly improved, and a series of world-class construction projects have become the eye-catching signs of "Made in China". The construction industry has developed from the traditional workshop era of on-site mortar mixing and "dusty" to the era of building industrialization of "building houses like cars", and is moving towards the era of digital construction. Building industrialization makes construction enter factory from construction site and transform from construction to manufacturing. The relevant person in charge of CSCEC Science and Technology Group told the reporter that they have made great efforts to develop the construction industrialization, and started the national layout of manufacturing bases several years ago. At present, they have 24 new construction industrialization manufacturing bases and domestic leading intelligent production lines. Taking CSCEC Shenzhen Shantou Fabricated Building Intelligent Factory as an example, the factory is equipped with 17 production lines, and has automatic production lines for double skin wallboards, prestressed components, prestressed composite slabs, prestressed double T plates, wallboards, fixed formwork, reinforcement, concrete, etc. It can produce beams, slabs, columns, stairs, balconies and various prestressed components. The design capacity is 220000 m3/year, which can meet the demand for prefabricated buildings of 2 million m3/year. The intelligent robot for steel bar binding has been used in the intelligent factory of Shenzhen Shantou assembly type buildings. The intelligent robot for steel bar binding can automatically identify and locate the nodes of the steel bar mesh cage. Through the software and hardware such as industrial six axis mechanical arm, tooling fixture, rotary workbench, integrated control system, etc., the automatic processing of the steel bar mesh cage for the bay window has been realized. The production efficiency has been increased by 4 times, the yield has been increased to more than 95%, and the efficient production, safe production High quality production. Assembled construction has promoted the energy conservation and emission reduction and production efficiency of the construction industry. Take Beijing Yizhuang Blue Collar Apartment Project as an example. The project is 32 meters high, with a building area of 120,000 square meters, and the overall assembly rate is 92%. Since 90% of the buildings have been manufactured in the factory, the construction site can be free of wet operation, and 70% of water can be saved, so as to achieve zero sewage discharge; No welding and other processes, which can save 70% of electricity; Scaffold free, reducing construction waste by 80%; The building materials can be disassembled and recycled, and the recyclability rate reaches 90%. Six workers on site cooperate with one tower crane to hoist four box houses every hour. If 4 tower cranes work at the same time, 88 box houses can be hoisted in one day, the hoisting accuracy can be controlled within 5 mm, and the construction speed is 60% faster than the traditional construction speed.
