The Analytical Investigation Of CS Assembly Structure

Early in 1980’s prefabricated construction had appeared in our country,the application range is relatively small,common component is the steel structures and prestressed concrete hollow slab,Early 21 st century,enacted Cold-formed thin-walled steel housing rules and regulations,From the early stages of development to today’s booming.From the early stages of development to today’s vigorous development,cannot leave the attention of the leaders and leading cadres at the provincial,Now assembly pilot cities and industrialization base has been all over the country.Prefabricated construction in China after thirty years of silence,the market for the comprehensive recovery and development.At the same time,the new assembly system should also be potential for further improving the assembly system the degree of industrialization and standardization.Cold-formed thin-walled steel reinforced concrete structure assembly system(Hereinafter referred to as Fabricated CS housing system)Mainly include the cold bending thin-wall steel,foam concrete,prestressed steel wire three kinds of materials.Cold-formed thin-walled steel is widely applied in light steel housing in our country,Cold-formed thin-wall steel structure,industrial production,light weight,is a kind of promising structure.Can do the main bearing structure such as steel beam,truss,column structure,also can do the secondary structure such as roof purlin,keel structure also can be used as retaining structures.Foamed concrete is a kind of materials recycling green environmental protection,energy saving effect is remarkable,and has incombustible of new energy-saving building materials,Through chemical or physical way,according to the need to air or nitrogen,carbon dioxide,oxygen and other gases into concrete,after reasonable maintenance molding,to form a closed porosity containing a large number of small,and has considerable strength of concrete products.Prestressed steel wire used to eliminate the prestressed spiral rib steel wire,prestressed steel used in prestressed concrete structure or structures of a steel wire,high strength ofmaterials,to ensure that the component strength at the same time can reduce the quantity of steel bar and save steel.Fabricated CS housing system,combined all the three kinds of materials together,with concrete assembly structure and light steel structure assembly,Insulation structure and integration,green environmental protection,construction speed is fast,high quality,building a house like made car technology,factory,standardization.Use the advantages of its material in CS housing system at the same time,also solve the problem in the combination of new,cold-formed thin-walled steel and combination of foamed concrete,cold-formed thin-walled steel and concrete,prestressed steel wire and concrete mix,solve the problem of how to raise in combination.Like the foamed concrete is a new type of energy efficient and environmentally friendly building materials,widely used in wall materials,but its still exist some shortcomings,such as low intensity,cracking,water absorption,so use page outside of cold-formed thin-wall steel and concrete wall will be foamed concrete isolation with the outside world,to solve this problem,the cold bending thin-wall steel skeleton stress structure,calculation model is established to calculate the cold-formed thin-walled steel bearing strength and stability,and don’t consider in the design of foamed concrete stress,and further research the issue of combination node in the design.Under the background of the industrialization of residential,promote the development of prefabricated houses,national and local policy releasing.Housing industrialization,the development design,production,construction,real estate,software development,equipment processing,cost consulting enterprise development together,Promoting the transformation and upgrading of the industry,change the traditional construction needs a large number of labor is given priority to with field wet operations,dosage of templates,many process,large amount of labor and time is long,and easy to waste materials of the present situation of the low repeatable utilization rate of resources.By 2017 pilot cities and industrialization demonstration base and demonstration project has been all over the country.Fabricated CS housing system for the development of environmental protection and energy saving and new type of prefabricated housing provides a new construction system,is committed to continuously improve and enhance the level of construction industrialization and overall performance.
