Stability Analysis And Security Control Of High Formwork Support System

In recent years, with the people in life increase demand for large space building, station, theater, shopping centers, landmark monuments such as large buildings are more and more appear in the urban construction. These buildings are more cast-in-place concrete structure, in the construction process, the high formwork support system of this risk larger engineering will get more application. However, due to the theoretical research in this field is not deep enough, the technology and management is not standardized, and the collapse accident has become a big problem for engineers and technicians..In this paper, the Euler formula and the calculation length of axial compression member are introduced, and the length coefficient of the axial compression member under different constraints is given.. The calculation method of the stability of the neutral rod is introduced.. The model and principle of the stability of the high formwork support system are analyzed.. Then in a beam of Anqing City Sports Center Natatorium tall formwork support system as an example, a detailed analysis of the specific design of, and in accordance with the specification gives the calculation method to calculate the design scheme is in line with the requirements specification. Then from structural engineering numerical analysis point of view, select appropriate models use the numerical simulation software ANSYS for calculation and analysis, are close to the results obtained with the theoretical calculation results, is less than the standard limit value of many, are in line with regulatory requirements. The two methods are also the verification method of the stability of the high template support system in engineering practice..Through the introduction of fuzzy comprehensive evaluation method of the basic ideas and principles, describes the steps of model construction and analysis of, of high and large formwork engineering safety evaluation system is established, including: design, site construction and safety management three aspects of content, a total of11influencing factors. Taking the tall formwork project of Anqing sports center as an example, the safety state of the high formwork is analyzed.. The result of the evaluation is reasonable, and the method is scientific, comprehensive and objective..List in recent years in our country some of the typical high formwork support system collapse, specific analysis that lead to accident reason, nowadays in practical engineering are summed up as:materials, design, construction and supervision of the four factors. Then from pre construction preparation stage; construction safety control; contingency plans and government regulation of the three big direction is given in detail on tall formwork engineering safety control should take concrete measures, hope future containing high formwork support system engineering can be paid.
