The main of the light steel wall are connected by mechanical means such as stainless steel rivets and Dacromet high-strength screws. This flexible connection method allows for a horizontal displacement range 8 to 10 centimeters between layers, which can relieve the pressure on non-load-bearing walls under the deformation of the main structure under earthquake conditions, prevent wall, and ensure the safety of pedestrians and residents' lives and property.
Light steel refers to cold-formed thin-walled light steel. material exhibits superior ductility, and its minimum elongation under cold working conditions is not less than 10%. The light steel structure, with its excellent energy-absorbing and ductility, shows very good seismic performance.
The overall rigidity of the wall is good, and it is less likely to appear concentrated fract or debris when damaged compared with masonry structures.
The weight of each square meter of light steel wall is estimated to be between 25 and35 kilograms, and its unit weight is only one-fifth of that of lightweight block walls and one-eighth of that of red brick walls.
The light steel structure building is light in weight, highly strong, with comprehensive rigidity and significant deformation capacity. The self-weight of the building is only one-th of that of the brick-concrete structure, and it has the ability to resist a hurricane of 70 meters per second, thus effectively guaranteeing life and property safety
The structure of the light steel structure building is entirely made of cold-formed thin-walled steel components, and the steel skeleton is made of highstrength, corrosion-resistant cold-rolled galvanized aluminum zinc material. This significantly reduces the impact of rust during construction and use, greatly increasing the service life of the components.7. Good insulation
The insulation and heat insulation materials mainly adopt glass fiber cotton, which shows significant insulation and heat insulation performance. The use of external wall insulation boards can effectively prevent cold bridge phenomenon of the wall, thereby improving the insulation effect. The thermal resistance performance of 100mm thick R15 insulation cotton is equivalent to that of a 1m thick brick wall.
Windows for light steel structure buildings are generally equipped with hollow glass, which can significantly improve sound insulation performance, with a sound insulation effect of more than 40 decibels. At the same time, the wall made of light steel keel combined with insulation material gypsum board has particularly sound insulation performance, with a theoretical limit of up to 60 decibels.
Dry construction helps reduce environmental pollution and reduce the production of, which is very environmentally friendly. The steel structure used in such buildings can be recycled in its entirety, and other auxiliary materials can also be recycled in large proportions, reflecting resource conservation sustainable development. The light steel structure buildings used are all green and environmentally friendly products, maintaining ecological balance and being beneficial to the health of residents
