Zheng Xuan, all-media reporter of Hunan Daily
Can't see the piles of garbage.，No dust all over the sky，You can't hear the noise for a long time。Wall panels pre-ordered from the factory、Components such as stairs，Put them neatly on the construction site，The workers put the components one by one.“Assemble”，Buildings sprang up one after another。This is the prefabricated building.——“Design standardization，Prefabrication of components in factory，Construction mechanization”。Liang Sicheng, a famous architect, conceived many years ago.“China's construction industrialization”，Is becoming a reality。Hunan actively demonstrates and promotes prefabricated buildings，More than one third of new buildings built last year were prefabricated buildings.。Prefabricated building industry，Regardless of the speed of development、Capacity scale，Or comprehensive strength，All of them are in the forefront of the country
Sany Miluo Industrial Park Project is the largest complete set of equipment and building materials research and development of Sany Construction.、Manufacturing base。
From hand“Build”To industry“Manufacture”：Prefabricated buildings transform traditional construction methodsWalk into Sany Construction Miluo Industrial ParkPC（Prefabricated concrete structures）Factory floor，Automatic operation of double-sided die table turning equipment on the production line，Piece by pieceA、BPrecise superposition molding of prefabricated cavity wallboard composed of two sides。Wall panels have always been used in construction.“Large piece”。Traditional construction relies on workers to pour on site.，The noise tends to rumble、Dust is all over the sky，Time consuming、Take pains not to say，It is also often affected by site construction conditions.，Buried and cracked、Water leakage and other hidden dangers。“Now，Complete the prefabrication work in the factory。”Xing Zhiyuan, Deputy General Manager of Central China Region of Sany Construction Technology Co., Ltd.，In component production，One production line of the factory can produce 150 components in 10 hours.，Meet the construction demand of 1500 square meters。

Sany Construction is a subsidiary of Sany Group.，With intelligent manufacturing experience and industrial Internet advantages，Focus on the main structure of concrete building，DevelopSPCS365 system，Design available、Manufacture、Construction、Software、Platform and other intelligent construction solutions，Enabling Building Investment and Planning、Planning and design、Production and supply、Construction and delivery、Full life cycle of operation and consumption。In the mainstream market，The main component products of prefabricated buildings are mainly horizontal laminated slabs.。SPCSTechnical route breaks the tradition，Vertical structure prefabrication technology as the core，Simplify the construction process to“Cavity wall stud·Equivalent isomerism·Die Fixture·In-plane operation+The golden horn and silver edge are poured after use.”，Realization“Overground and underground full assembly”。“Previously precast solid walls，Use sleeve grout，30 minutes、It takes three or four people to barely finish a piece.。”Xing Zhiyuan said，Use nowSPCSCavity wall，The volume of the cavity is large，The components are light，Easy alignment，Two people can complete the component hoisting in about 10 minutes.。Like this，A layer of rapid construction can be completed in 3 to 5 days.，Than traditional“Cast-in-place+Horizontal prefabrication”Spend 1 to 2 days less per layer。Efficiency is only one of the advantages of prefabricated buildings.。At the Sanyi Cloud Valley Phase II project site under construction，Scaffolding with almost no reinforcement formwork for in-plane operation，There is no accumulation of cement and sand.，The dust is flying。AdoptSPCSSystem construction，Reduce the input of on-site formwork by 55%，Labor decreased by 30%，Construction waste reduced by 50 percent%。

It is efficient、And environmentally friendly，But is the prefabricated building safe and reliable?？Xing Zhiyuan told reporters，SPCSThe system is independently developed.，Highly industrialized、Intellectualized complete production equipment，Accurately control the whole production process，Wall, column, beam and slab“One piece, one yard”Full control，Component quality is guaranteed，Higher quality throughout the building。Actually，Prefabricated building is not a new thing.。Western developed countries began to widely use it as early as the 1960s.。2016，Issued by the State Council《Guiding Opinions on Vigorously Developing Prefabricated Buildings》，China began to vigorously promote prefabricated buildings.。“With the development of construction technology,，Traditional construction industry is gradually transforming into construction industrialization.。”In Xing Zhiyuan's opinion，Prefabricated buildings have subverted the traditional construction concept.，Treat buildings as products、Treat construction as manufacturing,In line with the development direction of building industrialization，It is also an inevitable trend for the transformation and upgrading of the construction industry.。At present，Sanyi Construction is in Beijing、Shanghai、Guangdong、More than 10 provinces such as Hunan、Promotion and application in the citySPCSSystem，The total application building area is 25 million square meters.。Among，IntelligencePCDomestic open market share of equipment exceeds 50%，Over 800 production lines sold，Ranking first in the world。【Industry business card】Hunan prefabricated building industry started early.、Good foundation。At present，Two national assembly building demonstration cities have been built in the province.、20 industrial bases，Full coverage of assembly building production bases and project construction in 14 cities and prefectures，The annual production capacity of prefabricated building components and fittings reaches 35 million square meters.，The total industrial output value is more than 100 billion yuan.。Hunan is the only pilot province of green construction in China.，Prefabricated building development speed、Capacity scale、Its comprehensive strength ranks first in the country.。【Chain owner enterprise talk】The wave of construction industrialization is irresistible.——Cheng Weihua, General Manager of Sany ConstructionWith the disappearance of artificial dividends.、The continuous improvement of environmental protection requirements and the construction industry“Scatter、Chaos、Dirty、Poor”The current situation of the industry needs to be changed urgently.，In addition, the prefabricated building has its own“The construction speed is fast、And labor is save、Better quality”And other advantages，The vigorous promotion of prefabricated buildings has become an irresistible development trend.。Sanyi Construction General“Industrialize the building”As a mission，Insist on building to product、From construction to manufacturing、The idea of going from offline to online，Launched an industry-leading overall solution for intelligent construction，The prefabricated building is realized.“Structural safety and cost optimization、Green wisdom is so fast and economical.”，It is quite popular in the market.。2023，The total output value of the national construction industry is 31 trillion yuan.。Industry experts predict，The volume of the construction industry will remain roughly unchanged in the next three years.。By country《Guiding Opinions on Vigorously Developing Prefabricated Buildings》The proposed goal，The total output value of prefabricated construction industry is at least 7 trillion yuan.。
In the vast market space，Hunan has potential、Also have the ability to score more.“Cake”。We think，The key is to upgrade the construction industry with new technologies.，Actively promote the greening of the construction industry、Assembly、Digitize、Intelligent，Vigorously Cultivate the New Kinetic Energy for the Construction Industry to Develop New Quality Productivity。Sany Construction will continue to iterate the overall solution of assembly building and intelligent construction.，To contribute more to the high-quality development of Hunan's construction industry。
