Count the history of the development of prefabricated structures! -wellcamp light steel villa manufacturers
in the modern sense“prefabricated building”Originated from the industrial revolution and continues to develop, from a global perspective, the construction industry has developed in the past century. At the same time, the industrialization of construction has promoted the transformation of the production mode of the construction industry, greatly improved the production efficiency of the construction industry, and gradually popularized it. Through a comprehensive review of the development process of global construction industrialization, the development status of prefabricated buildings in developed countries, and the development history and status of prefabricated buildings in China, the problems and suggestions for improvement in the current development of prefabricated buildings in my country are systematically analyzed from multiple angles! The prefabricated building was defined in 1921,“build a house like a car”The concept was first mentioned by French architect Le Corbusier in 'Towards a New Architecture', hoping that the construction industry would be like the first half of the twentieth century.“Bulk copy”like a car,“Bulk copy”architecture. The American Construction Industry Institute (CII, 1986) defines prefabrication and preassembly in a basic report as follows:“Prefabrication is a manufacturing method, usually on specialized equipment, that combines various materials together to form a final installation part”. The Construction Industry Research and Information Association (CIRIA, 1997) defines pre-assembly as follows:“Preassembly: Organizing and completing most of the final assembly work for a product prior to final placement. It includes many forms of subassembly. It can be done on-site, or off-site, and often involves standardization”. From time to time we also hear various terms to describe the production unit of prefabricated buildings, for example,“Box”,“unit”,“module”or“collection, or part for assembly”. Early prefabricated buildings Prefabricated buildings in a broad sense include many contemporary and ancient building techniques, and bricks and blocks used in most parts of the world are perhaps the simplest prefabricated components. from the initial“Camp in winter, nest in summer”From ancient times to today, all the buildings created by human beings are basically“prefabricated building”. For example, China in ancient times (Hemudu culture) created a“beam and column” architectural“Tenon and tenon structure”,start to implement“prefabricated building”, and has continued to this day. The wooden mortise and tenon joint unearthed from the Hemudu Neolithic Cultural Site in Yuyao, Zhejiang Province is the earliest prefabricated building component discovered by archaeologists in the world so far. Similarly to the prefabricated wooden frame system in ancient my country, ancient Greek buildings from the 8th to 6th centuries BC were all made of wood or mud brick or clay. Around 600 BC, timber columns underwent a material change called petrification, all columns were made of stone and prefabricated. The structure of ancient Greek buildings is a beam-column system, and the main buildings in the early days were made of stone. Limited to material properties, the span of stone beams is generally 4 to 5 meters, and the maximum is 7 to 8 meters. The stone pillars are made of drum-shaped blocks, which are connected by tenon and mortise or metal pins, and the walls are also made of stone blocks. The important opportunity and boosting force for the development of construction industrialization in the first industrial revolution Around 1850, the first industrial revolution was basically completed, and the United Kingdom became the first industrial country in the world. The British Empire was in its heyday, and the Queen of England invited countries from all over the world to participate in the first World's Fair held by the British Empire. Joseph·Relying on the economy, precision and speed provided by modern industrial technology, Paxton (Joseph Paxton), for the first time, completely adopted the continuous production method of unit parts, and built large spaces by means of prefabricated structures, designed and built London The Crystal Palace, the venue for the World's Fair. The global construction industrialization process is closely related to the industrial revolution process, and the general development trend is getting closer to the development process of human civilization, and will lead the development and reform of the global construction industry! Now, in the future, we will also turn prefabricated buildings into the mainstream trend of our house building! in the modern sense“prefabricated building”Originated from the industrial revolution and continues to develop, from a global perspective, the construction industry has developed in the past century.
