Flexible manufacturing is to deal with the uncertainty of product end.

At present, the technology and cost control have not been fully customized and mass production.

“Considering the tight construction period, the construction of the hospital should separate the construction links above ‘plus or minus zero’ to the greatest extent.” Jiang Tao explained that “plus or minus zero” is the benchmark of the main project.

Some enterprises are worried about the lack of product supply.

The construction manufacturing industry is a heavy asset industry, which produces a large number of parts in advance, which needs to occupy a lot of funds and production resources; Renting and purchasing land for large storage yards are also increasing production costs..

Tang Fen believes that improving the universality of modules from the front end is to create conditions for the diversified cooperation of back-end assembly.

Jiang Tao revealed that after receiving the instruction of building huoshenshan hospital, China Construction Third Bureau needs to design, purchase and construction in parallel, and optimize and adjust according to the actual situation.

“If the production is fast, there is no place to put the products; if the production is slow, it will affect the progress of the construction site.” Tang Fen said that “inventory problem” is a common problem faced by most enterprises in production and operation.

Chen Yueqin, a precast building production workshop, photographed that the construction of huoshenshan hospital with a construction area of 33900 square meters and 1000 beds was completed in 10 days, while the handover of leishenshan hospital with a construction area of 79900 square meters and 1600 beds began in only 15 days.

The construction of huolei Shenshan hospital adopts the whole process BIM simulation construction technology to optimize the construction scheme, and deepen the design of column spacing, width, clearance, equipment hanging, door and window position in the foundation drawing, so as to leave valuable time for subsequent construction.

The factory is far away from the construction site.

Although the fire god Hill Hospital and Raytheon hill hospital are the emergency measures under the New Coronavirus epidemic situation, to a certain extent, it reflects the possibility of breakthroughs in the construction technology and speed of cast buildings.

However, what the “cloud supervisor” can’t see is that most of the construction and production of precast buildings are completed in the precast factory.

Jiang Tao, a staff member of China Construction Third Bureau Green Industry Investment Co., Ltd., told the economic observer that its main business is assembly construction.

HK) listed in Hong Kong in November 2019.

It is difficult for many cast component factories to customize and ship in a large number in a short time.

For example, if the quantity of goods in one factory is not enough, the component specifications of other factories can also be flexibly combined, and the drawings can be adjusted according to the actual situation of the connected source of goods.

Therefore, Yuanda residential workers disassemble one dimension from the architectural design side down, from the overall disassembly to modules, and then combine diversified buildings through standardized modules.

Therefore, the construction party needs to coordinate the component factories around Wuhan first, count the specifications, models and quantities of existing precast containers in the market, and then incorporate them into the design to maximize the use of assembled industrialized finished products.

Tang Fen introduced that this production method is only suitable for small-scale factories to deal with a small number of orders.

In order to realize the cooperation of multiple nodes, a complete set of digital system is needed.

Wu Hongtao, Party Secretary of the first company of China Construction Third Bureau, one of the contractors, said that behind this “Chinese speed” is the innovation of construction technology.

If you follow the traditional construction method, design first and then purchase in the market, it may not be available in the market.

is a company specializing in precast construction, which adopts a set of pc-cps intelligent manufacturing management system.

Jiang Tao believes that building a hospital in 10 days mainly benefits from the flexibility of assembly technology.

Because it coincides with the Spring Festival, many downstream factories of buildings have long been closed, and the reserves of workers and materials are insufficient.

After receiving the order, they remove the mold, produce all the parts, and then install the mold in the next link; Or because the product line is insufficient, only one kind of mold can be produced in batch before the production of the next mold.

Data driven is to solve the problem of uncertainty on the demand side.

When the parts below “plus or minus zero”, such as site leveling and hardening, foundation engineering, pipeline embedding, anti-seepage membrane construction, are constructed on site, the structural parts above “plus or minus zero” are also constructed simultaneously in major factories.

Dozens of processes go hand in hand, the time required for each construction plan is accurate, the on-site construction and overall hoisting are carried out alternately, and the deviation is corrected and connected in an orderly manner according to the on-site situation, “without wasting a minute and a second”.

The construction of the hospital should minimize the on-site operation of the ground works of the main building.

It is called “storage yard” in the cast construction industry.

Since 2016, driven by national policies, the precast construction market has ushered in a period of rapid development, including many enterprises taking this as the main business model, such as Yuanda residential workers (02163.

Tang Fen, President of Yuanda housing industry, explained the operation mode of pc-cps with “flexible manufacturing + data drive”.

Rational · constructive during the construction of Wuhan Huoshen mountain and Leishen Mountain hospital, everyone can view the scene of building module hoisting on the construction site through webcast.

After the stress skeleton and partition board in each ward are processed in the factory, they are directly transported to the construction site and installed according to the model, which is equivalent to the full assembly of the main structure and enclosure structure, “building a house like building blocks”.

The biggest secret weapon for the construction of the two hospitals of Huoshen mountain and Leishen mountain is the industrial assembly construction technology.

However, what the “cloud supervisor” can’t see is that most of the construction and production of precast buildings are completed in the precast factory.

Jiang Tao told the economic observer that huoshenshan hospital is composed of protective units.

During the construction of Wuhan Huoshen mountain and Leishen Mountain hospital, everyone can view the scene of building module hoisting on the construction site through webcast.

The “infrastructure myth” of racing against time and fighting against the epidemic once again promotes the cast construction technology into people’s vision.

He revealed that if the traditional concrete construction technology is adopted, the construction of 30000 square meters will take at least two years.

“The design scheme has been adjusted”.

The houses built by each real estate enterprise cannot be the same, and the factory production complexity is very high.
