The construction industry is one of the least digitized and least automated industries in the world. In the past hundred years, although technological innovation has continued, and the form and function of the building itself are also very different, the business form of construction has not changed significantly.
With the disappearance of the demographic dividend, China's construction industry is facing tremendous pressure on labor costs, as well as a series of problems such as high risks and low production efficiency. In the context of the transformation and upgrading of the manufacturing and service industries, the traditional construction industry has gradually lost its appeal to the younger generation. Among the existing modern technology systems, robotics is most likely to take on the important task of construction industry innovation. The emergence of construction robots will also change the original traditional construction mode.
1. The significance of the development of construction robots
1. Improve production efficiency
Construction robots are the only way to improve construction efficiency urgently. In the current building construction, although a large number of machinery and equipment have been involved, more processes still rely on manual work, resulting in a long construction period, ranging from several months to as many as several years. Suffering from inefficiency, only 11% of contractors think the construction site is very efficient. Problems in construction logistics have an impact on labor productivity of 50% or more. There are also factors such as design rework, inaccurate project data and communication errors.
2. Ensure personnel safety
Construction robots are the inevitable choice to ensure the safety of construction workers and improve the quality of work. The construction industry is recognized as a high-risk industry, with injury and death rates second only to mines and traffic accidents. For example, in the United States, the construction industry causes about 400,000 deaths and injuries every year, and the extremely high mortality rate has become a serious social problem. In addition, the working conditions of construction workers are extremely poor, heavy operations, and working environments full of mud, dust, noise, vibration, etc., greatly endanger the physical and mental health of employees and cause a high incidence of occupational diseases. If you want to free the construction workers from it, in terms of the current technological development level, robotics may be the best or the only way to solve this problem.
3. High material utilization
The construction industry is an industry with extremely dense resource requirements, and the traditional manual methods are extensive, and the use of building materials cannot be precisely controlled, resulting in huge waste of materials in the construction process. According to calculations by relevant departments, the material waste rate during the construction of an ordinary residential building is as high as 40%. In fact, if construction robots are used instead of manual construction, through reasonable current planning and refined operations, raw material waste can be greatly reduced, and even zero waste can be achieved. The use of robot technology can also implement the recycling and reuse of old building materials. These intangibles will reduce construction costs and also meet the value requirements of the times for building a conservation-oriented society.
4. Harmonious development of man and nature
Construction robots are an effective way to realize the harmonious development of man and nature. Traditional building constructions are all "intrusive" developments. Excavation first destroys the original vegetation. This method is very destructive to the natural environment. On the other hand, solid waste, waste water, and toxic and hazardous chemicals produced during construction can also cause great harm to the environment. In addition, the production of raw materials such as cement, steel, and glass also pollutes the environment. Under the background of the era of advocating environmental protection, how to achieve more environmentally friendly construction and development, reduce garbage and waste emissions, and improve the utilization of raw materials are all urgent requirements of the era for the innovation of the construction industry. The future digital construction technology represented by construction robots is expected to completely reshape the face of the construction industry and achieve truly green, environmentally friendly and pollution-free construction.
5. Combination of design and entity
From the perspective of the evolution and innovation of architectural technology, robotics is expected to build a bridge that connects the design concept and the entity directly, so that the architect’s vision can become a reality more quickly. Digital construction technology represented by construction robots is a powerful tool to connect the digital world and the material world. It allows creativity and design in the virtual environment to further transform from digital information to material reality. Construction robot technology is more efficient in repetitive production, and it can also realize the possibility that human hands cannot achieve in non-standard construction.
Two, construction robot application
1. Drilling robot
The traditional operation method relies on manual + impact drill, which is inefficient, lacks precision and expensive. Mobile robots are specially designed to solve drilling problems and are suitable for various construction site environments. They use relatively low-cost standardized components for production, and the operating system is completely designed by themselves. Compared with the existing industrial robot control system, the system is more friendly. Workers can remotely control the robot through mobile phones and computers only after simple training.
2. Wall-building robot
Construction robots can read drawings and use 3D scanning technology to accurately calculate the position of each brick, which is much more accurate than construction workers.
3. Ceiling construction robot
4. Paint the robot
5. Panel installation robot
The board installation interior decoration robot system is mainly developed for the indoor large-size and large-quality board dry hanging installation process. The system can meet the decoration of large venues, halls, railway stations and airports, such as marble siding, glass curtain walls, and ceilings. And other installation requirements. This robot system does not need to build scaffolding during plate installation work, and a wide range of mobile operations can be completed by two operators.
