For example, in ancient times (Hemudu Culture), China created the “tenon and mortise structure” of “beam column” architecture and began to implement “precast architecture”, which has been handed down to this day.

Ancient Greece belongs to the first industrial revolution of beam column structure system architecture, which is an important opportunity and driving force for the development of architectural industrialization.

The construction industrialization characterized by housing industrialization first rose in the industrial developed countries dominated by the West.

According to the internal causes and performance of the development of global construction industrialization, it can be roughly divided into the following four development stages.

1: Building industrialization 1.0 era: industrialization and mechanization (from the beginning of the 20th century to the middle of the 20th century).

All columns were made of stone and pre manufactured.

He hoped that the construction industry would “copy” buildings like “batch copy” cars in the first half of the 20th century.

The development process of global architectural industrialization of the Crystal Palace in London, which is being built with precast parts, is closely related to the process of industrial revolution.

Bricks and blocks used in most parts of the world are perhaps the simplest precast components.

Definition of precast architecture in 1921, the concept of “building a house like a car” was first mentioned by French architect Corbusier in moving towards new architecture.

The American Construction Industry Association (CII, 1986) defines pre manufacturing and pre assembly in a basic report as follows: “pre manufacturing is a manufacturing method, which generally combines various materials on special equipment to form a final installation part”.

At the same time, urban development has brought a large number of farmers to the city and a large number of people into the city, A large number of houses, office buildings and factories need to be built in a short time, which has laid a foundation for the creation of construction industrialization..

The Crystal Palace has experienced the whole process from design conception, production, transportation to final construction and demolition.

Limited to material properties, the span of stone beam is generally 4 ~ 5m, but the maximum is 7 ~ 8m.

It was once one of the general reviews of cast iron technology in the first half of the 19th century.

The general development trend is closer to the development process of human civilization and will lead the development and reform of the global construction industry.

The construction industry research and Information Association (CIRIA, 1997) defines pre assembly as follows: “pre assembly: organize and complete most of the final assembly work for a product before it is finally in place.

It includes many forms of sub assembly.

Relying on the economy, accuracy and rapidity provided by modern industrial technology, Joseph Paxton completely adopted the continuous production mode of unit parts for the first time, built a large space by means of assembly structure, and designed and built the Crystal Palace, the venue of the London World Expo.

The British Empire was in its heyday, and the Queen invited countries all over the world to participate in the first World Expo held by the British Empire.

Similarly, ancient Greek buildings in the 8th-6th century BC were made of wood, mud brick or clay.

Mortise and tenon structure for fixing vertical components wooden mortise and tenon excavated from Hemudu Neolithic cultural site in Yuyao, Zhejiang Province is the earliest precast building component discovered by Archaeology in the world so far.

The first large-scale precast public building, the Crystal Palace in London, was completed in less than six months.

In the early stage, the main buildings used stone.

From a global perspective, the development of the construction industry in the past century.

The structure of ancient Greek architecture belongs to the beam column system.

Magnetic Thread Disc

It is 408 feet wide and 1851 feet long.

By comprehensively reviewing the development process of global building industrialization, the development status of precast buildings in developed countries, and the development history and current situation of precast buildings in China, this paper systematically analyzes the problems and improvement suggestions in the development of precast buildings in China.

Around 1850, the first industrial revolution was basically completed, and Britain became the first industrial country in the world.

It can be carried out on site or away from the site, and often involves standardization”.

From the ancient times of “camp cave in winter and nest in summer” to today, all buildings created by human beings are basically “precast buildings”.

The stone column is made of drum shaped blocks, which are connected by mortise and tenon or metal pins, and the wall is also made of stone blocks.

The earliest prototype of Maison domino in Le Corbusier Maison citrohan series.

Although it is carried by horse, it pioneered the technical mode of factory precast components and on-site assembly, which is the first work of modern architecture (steel skeleton and glass curtain wall).

With the rise of the second industrial revolution and the end of the first World War, the economic recovery of European countries and the progress of technology have brought the development of modern building materials and technology.

It is a complete precast construction system project.

“Precast building” in the modern sense originated from the industrial revolution and developed continuously.

We often hear a variety of terms to describe the production units of precast buildings, such as “box”, “unit”, “module” or “set, or parts for assembly”.

It has five floors, three floors high and a construction area of about 74000 square meters.

While rapidly meeting people’s housing needs, the construction industrialization promoted the reform of the production mode of the construction industry, It has greatly improved the production efficiency of the construction industry and gradually popularized it.

In a broad sense, precast architecture includes many contemporary and ancient architectural technologies.

Around 600 BC, wood columns underwent a material change called petrification.
