Steel structure as a commodity, and ultimately to allow consumers to benefit, so that they recognize that the feeling of buying value is the hard truth.
In the view of Li Wenbin, life safety is the first rule of the residential, in the high-rise buildings in the city, the frequent earthquakes in and steel structure residence of life has powerful ability of care and its security is in the best interests of the tenants.
A survey shows that poor seismic performance, collapsed houses is lead to casualties, at home and abroad in recent years occurred one after another earthquake further proved that the seismic performance of steel structure residential and public buildings.
Li Wenbin cite repeated destruction of test data: interlayer displacement angle is less than 1 / 200, and CCA in grouting wall without any cracks; interlayer displacement angle is 1 / 90 wall produces only partial cracks or extrusion, as long as slightly repair can be restored using does not harm security personnel. Can satisfy the requirement of the deformation of the main structure of the main structure in the earthquake.
And as early as 2003, the Taiwan national successful university architecture department professor Zhang Jiaxiang on the CCA board grouting wall of the nail holes, plate joints cracking, cracking and other damage test plate. The change of 1/40 in the structure of the main body layer is not destroyed at the 31%, 21.5%, 11.5%, 1%, CCA.
Practice has proved that Hangxiao multi-storey and high-rise steel structure housing system not only the seismic performance of the steel structure of the main well, Jharkhand CCA board grouting wall also has excellent seismic performance, so in Southeast Asia, Taiwan, Hong Kong and widely used.
Green environmental protection material is also a guarantee for the safety of steel structures.
Li Wenbin told reporters that Hangxiao and Zhejiang University, Tongji University, the national building materials testing center more than a dozen scientific research institutions to cooperate, 60 items of system testing and, the properties are to meet or exceed the requirements of national standard. Experimental results show that the CCA board 100% does not contain asbestos, benzene and formaldehyde, and other harmful substances harmful to human body, no any radioactive, scope of use is not subject to any restrictions, belonging to the A-class non combustible material, in case of fire, plate index and smoke toxicity index is zero.
The comfort of steel structure is also favored by the tenants.
Due to the structural steelwork residential use of beam column system, inner sleeve without bearing wall, space permeability, for the flexible arrangement of space function, can meet the needs of multi-level households, households according to different periods of population structure adjustment room layout provides maximum convenience. Coupled with the structural steelwork residential window is not restricted, daylighting is ventilated effect is good, provide a safer and more comfortable living space for people.
Steel structure residential energy-saving heat preservation effect is good, during use, winter for tenants to save on heating costs, households save cooling expenses for summer, after a considerable period of time is a not a small numbers.
The improvement of steel structure housing utilization ratio is the most obvious benefit to the tenants.
For many years there is an unwritten rule, consumers buy a house is in accordance with the construction area to pay the principal, and the actual enjoyment is the use of the area. Steel structure residential buildings due to the small size of the structure, the wall is thin, so the area of high utilization, people spend the same construction area of the money, can get a greater use of space. Wuhan century home on the 5th floor, unit B, for example, Li Wenbin analysis: in the construction area of 137.6 certain circumstances, the effective area of the steel structure was 80.8%, concrete structure was 77.5%; the use of the area increased to 3.3 square meters.
Wuhan region, for example, if the average price of residential housing for 8000 yuan /m2, consumers buy Wuhan century home building B 5, after the, the implied income is 26400 yuan. As can be seen, the consumers to buy building of steel structure and the same construction area of the concrete structure housing purchase compared to not only get more use area and more considerable economic benefits.
