development prospects and green design elements
More accurate and reduce the damage, there is undoubtedly a fast and convenient inspection and testing techniques to improve and enhance the development goals. Development of new test items, so that a more complete inspection and testing technology is the technology development.
Testing instruments and equipment in the structure of the inspection and testing technology plays an important role. No equipment will not be able to detect, but good quality, easy to operate test equipment is of high quality job security. Compared with developed countries, our testing equipment, in general, there is a clear gap, mainly reflected in the performance instability, less functional, life is short, bulky and so on.
Detection methods improve and enhance the detection of the second aspect of the theory to enhance and improve the detection of data analysis methods. Reasonable assurance as to detect the number of rational arrangement of the detection position, reducing the uncertainty of test results, make full use of test data, etc., are all structural inspection and testing of the problems faced.
With the development of engineering and testing requirements increase, some of the new problems facing us, such as high-strength concrete strength testing, defect accurately determine concrete, prestressed pipe grouting plumpness testing the strength of new wall materials test methods and quality assessment methods.
Steel inspection and testing is the most promising technology. When the identification of steel structures, steel structures physical and mechanical properties of materials on-site non-destructive inspection test technology, steel components stress field nondestructive measurement techniques and structural damage to key parts of the stress and field testing technology is yet to be developed technologies. Steel construction team
But also the introduction of new technology development and research combined. Such as light sensing technology, acoustic emission technology in the late nineties are internationally advanced technologies in large construction projects during the construction phase and the use of security surveillance and security structures actual load test site, etc., a relatively broad application prospects.
Steel green building design elements
Construction industry is a resource and energy consumption, heavy pollution industries, as human consciousness to continuously improve the environment protection and energy, green building has become popular. However, some advertised as "green" building design and management is unreasonable because, not only spend more money, but also did not achieve the desired energy-saving effect.
First, to ensure that the health
Green building design is an important task is to ensure the health of users, to ensure indoor air quality, thermal environment, noise and electromagnetic radiation and other factors that impact on people. Design as much as possible using low or non-toxic materials, such as walls and ceilings using non-toxic or low toxic paints, building materials Voc content without formaldehyde or at least, ceramic, hardwood and other hard surface decoration, etc.; selection of materials, building systems and machinery system to minimize wood, carpet, paint, sealant, fabric and other potential adverse health contaminants, rational organization of natural ventilation, set the inlet and outlet required, the wind burglary. Improve the indoor thermal environment, including temperature, humidity, radiation, temperature and air flow, etc., improve human comfort. Improve water quality, drinking water conditions can be selected. Reasonable for natural lighting, which meet the needs of human health, but also to meet the needs of visual aesthetics, while achieving energy saving effect. By improving the detail design and construction methods, and the use of sound-absorbing material to improve building insulation.
Second, the rational use of resources
a. use of clean energy
Solar energy is a clean energy resource-rich, can be strong in the construction of solar energy utilization, such as the design and construction of solar photovoltaic roof, solar power and solar photovoltaic glass walls, the solar energy into the building itself needs electricity and heat. In addition, the development and utilization of wind energy is a relatively square more of a clean energy, in addition to naturally ventilated buildings, you can also install wind power and wind-induced thermal equipment, convert wind energy into the building's energy can be used directly.
b. recycling old materials
Increase the recycling of old materials as much as possible to reduce energy and material inputs and outputs of waste and pollutants, which is the most important green building system internal mechanism. May be in the process of building demolition materials, such as wood flooring, wood products, precast concrete, iron, steel, masonry, insulation materials, through processing and transformation, to meet the specifications and design requirements under the conditions of use of the new building.
c. use of renewable raw materials
Building to increase timber, paper / fiber insulation materials, etc. The use of renewable raw materials, not only fewer construction investment, but also alleviate human over-exploitation of natural resources caused by ecological problems.
Third, reduce environmental load
Making green building design process, should pay attention to mitigate the damage to the natural environment, reduce environmental pollution, the building construction waste generated solid, gaseous pollutants such as sewage and bring minimal environmental load.
1 Select the environmental impact of building materials
Building production process will consume a lot of resources and energy, and lead to higher environmental pollution. Architects in the material selection, should have the awareness of ecological and economic, select a small load on the environment caused by materials such as eco-cement, green concrete, high performance and longevity of construction materials, home comfort and health of building materials technology. Prefabricated modular components can be used to reduce construction waste. Installation of steel structure
(2) using a reasonable method of construction
Architectural design should take full account of the pollution caused by the construction process, the building design, material selection and process design should facilitate the construction, reduce energy consumption and reduce their construction the environmental load.
