Light steel structure housing cost VS steel mixed house cost
Light steel structure house as a new type of construction with its "energy saving and environmental protection", "comfortable and fast" "earthquake resistant wind" and many other advantages to attract a lot of eyeballs. With the popularity of light steel structure housing in China, many people began to question the quality of the shift from the quality of this piece. The following are the three elements of light steel construction cost analysis of light steel structure housing and steel structure of the housing.
Residential, is a residential products different from the main criteria for the classification of other residential products, is in the residential products to form the physical nature of some things, namely residential products showed the applicability, safety, economy, environment etc.. The applicability includes: barrier free facilities, building decoration, ventilation, lighting, indoor sound insulation, seismic, heat insulation, residential renovation, equipment and facilities, housing plane and space layout; safety including safety hazards, toxic and harmful substances in daily safety and prevention measures of gas and electrical equipment safety construction, fire safety, building structure; economy includes: material, water, land, energy saving; environment includes: public service facilities, environmental sanitation and outdoor noise, architectural style, green space and environment, intelligent systems, residential land and planning. The cost of construction refers to the life cycle cost, that is, the total cost of the product in the life cycle.
First, the weight of the house
The influence of the weight of the structure on the cost of steel construction of light weight; secondly, in the light steel residential structure system, walls and floors are mostly light materials. After the construction of the main structure than other traditional materials to reduce about 30%. The upper structure adopts light steel structure, the foundation load can be reduced by nearly 1/ 2, and then the ground resistance requirement of the foundation is reduced. This will make the foundation treatment work is simple, reduce traffic, reduce cost.
Two, the construction area
Analysis of 3 different residential structures. For example, brick and concrete structure was applied in a 2 storey residential building, building area of about 400m2; reinforced concrete structure with a 3 storey residential buildings, construction area of about 550 m2. Through the calculation and analysis, the use of two different structures of the area were 73%, 78.4%. At present, the light steel structure of the area utilization rate of more than 92%. If the average price of steel is 2000 / m2, to increase the construction area, compared with brick and concrete structure can obtain the implied earnings for 136800 yuan; compared with reinforced concrete structure can obtain the implicit income is 97920
Three, construction period
1) increase in construction period, the time of the work of the workers in the field of growth, every day to pay a certain fee, so the increase in time will bring an increase in costs.
2) increase in construction period, owing on the loan for a long time, the total number of loans also increased. From the point of view of economic efficiency, shorten the construction period is more prominent than the cost reduction, it will bring considerable economic benefits for the owners
The economic performance evaluation of light steel structure housing, and steel and concrete, brick and concrete structure are compared. It can be seen that although the light steel structure housing cost is slightly higher, but it has incomparable advantages of traditional residential structure, in line with sustainable development strategy. More importantly, it is significantly higher than the cost of traditional residential. I hope to provide a useful reference for the vast number of consumers to change the past light steel structure housing is not a comprehensive understanding and evaluation, so as to better promote the development of light steel structure housing in china.
