ã€China Aluminum Industry Net】 “The concrete that has just been demolded will have smooth surfaces like mirrors, and it will be able to meet the inspection standards without the need for plastering any more!†said the newly introduced aluminum alloy in the Zengcheng International Garden Project Department of China Railway Construction Group II. The stencil process attracted the visit of the brother construction unit and was praised by the visitors.
Aluminum alloy formwork is a turning material that has only gradually emerged and promoted in recent years. Its light weight, high strength, large board width, and less patchwork features effectively ensure construction quality. China Railway Construction Group Co., Ltd. accurately smelled the market value of the aluminum alloy formwork, quickly introduced the construction technology, took the lead in the pilot project of the Zengcheng International Garden Project Department, and achieved good results.
It is reported that after using the aluminum alloy formwork process, the qualified rate of concrete construction in this project is almost 100% in terms of perceived quality, flatness, verticality, and cross-sectional dimensions, which is well verified in actual measured data. And this is also unmatched by traditional templates such as wood forms. This is due to the superior strength, stiffness, and stability of aluminum alloy templates. Traditional wood stencils often occur in the form of mold up and explosion, and they do not occur on aluminum alloy stencils.
In addition to high-quality construction quality, the high turnover rate is a major advantage of this process. An average of 4.5 days a layer, less than the wooden mold or steel mold turnover period of 3 days or more. Rapid turnover comes from the simple and convenient assembly of the aluminum alloy construction template system. "Quick-release quick-release system" and uniform weight 30KG/?, aluminum alloy formwork can be completely assembled by hand, without the need for other mechanical equipment to assist, workers usually only need a wrench or small hammer construction, convenient and quick, reducing the template installation About 30% artificial.
Compared to the 3-5 times turnover life of the wooden formwork, the turnover ability of the aluminum formwork over 200 times is also a feature favored by the company. Wood formwork uses huge forest resources and affects the ecology. The aluminum template not only has a high turnover rate but also can be recycled after being scrapped. According to relevant statistics, in 2013, the amount of building templates used in China exceeded 800 million square meters. If 20% of them use aluminum templates instead, they can save 160 million square meters of timber formwork, equivalent to saving 400,000 tons of standard coal and reducing emissions by 1 million. Tons of carbon dioxide.
In addition, the use of a wide range of materials, less on-site waste, low turnover costs, high salvage value, and good safety performance also make this process a substitute for traditional wood formwork. At present, the aluminum alloy formwork pilot project of the Zengcheng International Garden Project of the China Railway Construction Group Company II has been successful. The next step will be to promote the green process in various project departments such as Shanghai, Nanning and Changsha.
Water level sensor, alose called hydrostatic pressure level sensors, submersible level sensors, which are submersible level sensors used for measuring the level of liquids (including corrosive liquids) in deep tanks or water in reservoirs. It provide accuracy and reliability across a wide range of applications. Based on the principle that the measured liquid static pressure is proportional to the height of the liquid, the advanced isolation type diffusion silicon sensor or ceramic capacitive Pressure Sensor is used to convert the static pressure into electrical signals, and then through temperature compensation and linear correction, into standard electrical signals (generally 4-20mA/1-5VDC).
