In Japan, about 200,000 new low-rise buildings are built each year, with a construction area of about 3 million m2. Most of them are Light Steel Frame house, especially light-weight steel-structured houses. The light steel structure-assembled house was popularized in Japan due to the 1995 Kobe earthquake. Especially after the 1995 Kobe earthquake, the epicenter of Hyogo Prefecture implemented the "Flying Birds" plan, requiring buildings to suffer an earthquake of magnitude 8; The Japanese government has proposed a "zero death" plan. Therefore, various state-of-the-art anti-vibration methods such as light steel structures and lightweight materials with excellent seismic performance are widely used, and all the old buildings are all reinforced with different shapes of light steel structural frames.

There are 7-8 manufacturers of such industrialized houses in Japan, and they only use 2-3 kinds structure systems.

The Japanese government and companies are studying:

(1) How to improve the durability of residential buildings and what kind of durability is appropriate.

(2) Adapting to the values of family change and reaction to the house, studying the “framework and household separation plan”, the main structure part is built very firmly, with durability of more than 100y. Causes no large column space.

China's towns and villages have huge disadvantages in existing homes, and steel-structured houses can just make up for the good. In fact, the advantages of steel structure house in environmental protection are more prominent. Light weight, shock resistance, temperature insulation, waterproof, heat insulation, sound insulation, low overall cost (because of its light weight, reduced basic costs, reduced overall materials, reduced direct costs, short construction period, and reduced indirect costs) The low comprehensive cost) These well-known items are not necessary to elaborate. It is common knowledge to realize 100% waste recycling after scrapping steel. It is not rarely for roof truss collapsed, construction error, which leads to dangers to human. Even with construction drawings, how? While implementing to construction workers, it relates to uncertain. So prefabrication house will be the trend for house structure, regardless of many problems.

We FrameMac only focus on designing, manufacturing Light Gauge Steel Frame Making Machine For Prefabricated House for manufacturing LSF construction. For different construction system standard in different countries, for different design software, for long-time continuous production mission, we could easily face the problems you are facing. The system features:

(1) Good seismic performance. The steel structure has good ductility, energy consumption during earthquake, and easy repair after earthquake; the system has light weight, low frequency and less earthquake action.

(2) Fire protection. The solid material covers the steel column to form a 1.5 hour protection.

(3) Energy saving. The thickness of the filling insulation foam can be adjusted in the external wall of the spray casting, and the energy saving effect is good; the solid material covers the steel member, and the cold bridge is avoided.

(4) Strong sense of entity and high nailing power. When the wall is impacted, there is no hollow feeling, and the nailing force can reach 100kg.

(5) Material saving - circular economy. The steel can be recycled and recycled with polystyrene particles, which is in line with the principles of circular economy and sustainable development. Representative project: Daxing Anding Town Model House. Built in 2004, the area: 500m2, steel frame-light steel filled composite structure, construction period of 26 days, the main body cost 1800 yuan / m2, fine decoration 1700 yuan / m2.
