Ensure construction safety, improve construction quality and improve construction efficiency.

In recent years, a new round of “industrial revolution” is set off in the construction industry. In the whole process of construction, the intelligent construction era of increasing the integration and innovative application of new technologies, accelerating the coordinated development of a new generation of information technology and building industrialization technology, and building houses with robots has come.

Recently, the research team of China Construction daily came to Guangzhou and Foshan, Guangdong Province, walked into Guangdong bozhilin robot Co., Ltd. (hereinafter referred to as “bozhilin”) and went to the project site to explore the development and application of bozhilin construction robot.

Multi skill body

“Pink worker” appears on the construction site

Country garden · Xingxi project, located in Zengcheng District, Guangzhou, is one of the projects that bozhilin is responsible for participating in the construction. At present, the main building of the project has been basically completed and is in the stage of internal decoration.

Standing outside the project site, the pink construction elevators on several building exterior walls are particularly conspicuous. Pink is the uniform color of bozhilin construction robot. In the country garden · Xingxi project, this color is very common. Construction robots dressed in “pink clothes” shuttle through the construction site, floors and houses, making it full of “cute” flavor.

Put on your helmet and walk into the construction site. Within a few steps, you can see a chubby building cleaning robot walking back and forth in the corridor with big eyes.

The roads in the construction stage are pitted and uneven, there are many kinds of dust such as cement ash, wall ash and muck, and there are small stones and small fragments from time to time… The seemingly simple cleaning work increases the difficulty on the construction site, but it can’t help the multi skilled building cleaning robot.

Multi sensor fusion technologies such as lidar, ultrasonic sensor and anti-collision strip enable the building cleaning robot to operate safely under complex road conditions; The design of double filter elements and double air ducts allows the building cleaning robot to easily complete the cleaning work without stage fright when facing heavy dust. Compared with manual cleaning, the operation efficiency of building cleaning robot is increased by three times, and the cleaning effect is also more excellent.

Take the intelligent construction elevator, walk into the building with the indoor spraying robot, cross the corridor and reach the lobby of a family, and then it begins to work. As it walked, it waved its mechanical arm up and down, sprayed latex paint evenly, and completed the spraying of one wall. Thanks to the multi angle flexible moving arm, the indoor spraying robot can not only complete the full-automatic spraying of wall primer and finish, but also the spraying of bay window, beam, ceiling, gypsum line and other positions.

While the indoor spraying robot works, in another room, the measuring robot is standing in the center of the room, turning its “eyes” rapidly 360 degrees. Within 2 minutes, the data collection is completed, and various reports are generated and transmitted to the digital platform. AI (Artificial Intelligence) algorithm allows it to measure the wall burst point, ceiling levelness, internal and external corners, squareness and other data of the room with high accuracy, and the measurement accuracy is within ± 1mm.

12 product lines

The steel team covers the whole construction cycle

Construction robots can not only show their skills in the decoration stage, but also in the earlier concrete construction. “Through the application of intelligent follow-up distributor, ground leveling robot, ground leveling robot and basement polishing robot, the efficiency is higher and the safety is also improved.” The project manager of country garden · Xingxi project said.

The traditional concrete pouring operation of high-rise buildings requires three workers to complete the distribution work together, which not only tests the technical proficiency of each worker, but also requires the cooperation of many workers. In the country garden · Xingxi project, with the help of the “pink worker” of the intelligent follow-up distributor, one worker can easily complete the concrete pouring operation. In addition to remotely controlling the distribution arm of the intelligent follow-up distributor to reach the specified position through the handle to realize accurate distribution, you can also select the automatic mode and use the intelligent algorithm to make the intelligent follow-up distributor operate independently.

After the completion of concrete pouring, how to deal with the phenomenon of potholes on the ground? At this time, it is the turn of the ground leveling robot of “working surface flatness ± 5mm” and “fully automatic leveling construction”.

The two degree of freedom adaptive system, high-precision laser elevation control system and real-time control system enable the ground leveling robot to work stably on the reinforced concrete and always maintain the accuracy of millimeter level accuracy; With the support of the navigation system, the planning path can also be set automatically to realize full-automatic leveling construction. With the ground leveling robot, the flatness requirements of the concrete leveling layer can be met in the construction stage of the main structure, so as to speed up the project construction progress and improve the construction efficiency.

It is understood that bozhilin is a wholly-owned subsidiary of country garden group. In the bozhilin construction robot exhibition hall located in Foshan, dozens of construction robots, including intelligent follow-up distributor and ground leveling robot, are arranged neatly. At present, bozhilin has formed 12 construction robot product lines, including concrete construction, concrete trimming, bricklaying and plastering, interior wall decoration, etc., involving the construction links of main structure, secondary structure, decoration, electromechanical installation and so on, basically covering the whole construction cycle.

By the end of 2021, the vast majority of the 46 construction robots being developed by bozhilin are generally used in cast-in-situ concrete technology and prefabricated building construction, of which 18 construction robots have been put into commercial application.

In projects such as Fengtong garden in Shunde, Foshan, Haina garden in Pingsha, Zhuhai and meisheshi home in Haikou, scenes of human-computer cooperative operation are in full swing, writing the dream of “building a house by robot” into reality.

In various projects, bozhilin construction robot has made breakthroughs in many aspects, including completing the participation of robots in the construction of demonstration areas, establishing robot dispatching centers, and implementing the multi machine joint construction mode of finishing robots.

work steadily

Multiple independent research and development core technologies

In the intelligent era when various industries step up the empowerment of science and technology, the digitization and automation of the construction industry are low, and more extensive production methods such as “moving bricks, binding reinforcement, pouring concrete and installing formwork” are still common.

The construction site has the characteristics of poor working environment, large scene difference and complex and changeable construction surface. The construction robot is very different from the industrial robot and other products in the requirements of core parts and core algorithms
