Recently, the country’s first standardized assembly building demonstration project was settled in Pudong, Shanghai.

After the overall construction of traditional PC, the external wall also needs external insulation, which causes a series of falling off.

Lianlong external wall board adopts internal insulation to eliminate the potential safety hazards of the external wall.

On January 18, the reporter saw at the seventh floor construction site of building 4 that the modular precast shear wall, infilled wall, beam, staircase and other components of Lianlong company were installed in an orderly manner, and the technical installation personnel were carrying out wall panel hoisting and other operations in an orderly manner.

Dozens of industry experts and professors from East China design and Research Institute and Tongji University were invited to observe the construction site of Lianlong precast buildings and watch the publicity video of the enterprise’s intelligent production line.

“Intelligent production line and modular self insulation concrete shear wall structure system and precast component products are the highlights of our project.

As a high-tech enterprise in Jiangsu Province, in the past seven years, Lianlong company has cooperated with East China Architectural Design Institute, Tongji University, Shanghai University, Shanghai seventh construction group, Shanghai Zhongsen and other institutions and enterprises to carry out the design, R & D and production of modular self insulation structural components, and has successively invested 140 million yuan, Ll20-150w assembled self insulation shear wall special intelligent production line with completely independent intellectual property rights has been developed to produce modular assembled self insulation concrete shear wall precast component products.

At present, the system is the first in China, standardized and modular integrated insulation, and the whole process of intelligent manufacturing and intelligent construction, which has a great advantage.” Li Xinhua, a national expert in the evaluation of precast buildings and green buildings and President of Shanghai Zhongsen precast Engineering Research Institute, said.

Gong Zuping, chairman of Lianlong company, said that the enterprise will continue to climb and surpass on the road of independent innovation and contribute wisdom and strength to continue to lead modern precast buildings.

Erection Anchor

Shi Jianhua, the project manager of Lianlong company, said that compared with the traditional flat formwork production mode of precast buildings, Lianlong company uses side formwork production, covering only half of the former; The self-developed intelligent production line requires only one-third of the labor of the former, but the production efficiency is more than three times higher.

“The intelligent manufacturing of Lianlong company has realized the automation from steel bar blanking, binding, formwork assembly, concrete pouring, and then to maintenance and stacking, which can basically realize unmanned.

At the beginning of the new year, Nantong Lianlong intelligent production line was selected into the list of the first major equipment in Jiangsu Province in 2021.

In order to further improve the level of intelligent construction, Lianlong held an on-site observation Seminar on the standardization, modularization and self insulation of precast buildings in Shanghai last month.

In December 2020, the assembled integral self insulation shear wall structure system developed by Lianlong company passed the evaluation of scientific and technological achievements of the Ministry of housing and urban rural development, and was listed as a national scientific and technological achievements promotion project in the construction industry by the science, technology and industrialization development center of the Ministry of housing and urban rural development.

The project has 12 residential buildings with a total construction area of more than 100000 square meters, which is implemented by Nantong Lianlong Assembly Building Technology Co., Ltd., a private enterprise in Haimen.

Now it is in the market in Shanghai Some of our units have a great interest in our thermal insulation “.

The experts fully affirmed the persistent and innovative spirit of Lianlong company, and put forward their insights on optimizing the process flow and increasing robot installation on site.
