| Summary: | 碩士 === 嘉南藥理大學 === 職業安全衛生系 === 106 === In recent years, the appearance of old buildings in the skin and repair operations, related to the external wall frame construction of the occupational disaster accident spate, according to the Ministry of Labor related Statistics, the construction of disaster for all kinds of labor disasters occurred first, and in the construction of occupational disaster cases, The collapse (collapse) and falling disaster caused by the construction frame as media event also accounted for a large proportion, so it is urgent and necessary to discuss the stability of construction frame.
The construction frame is used widely in the building project, but because it belongs to the temporary structure, its safety is usually easy to be neglected, and the major occupational disaster statistics show that the construction frame has been the first in the high occupation disaster media. In addition to the unsafe behavior of the workers in the field, the main reasons include the insufficient strength of the construction frame and related components, the repeated use, the old unbearable, the non-standard standard products and the lack of safety protection facilities, and the site management of the building industry.The mechanism is not perfect, also causes the construction industry to cut down the vicious competition for a long time, causes the spate accident accident.
Looking at the construction frame of exterior wall of domestic building, in the construction stage or a typhoon during the collapse of the accident investigation, showing that the moment of strong wind is suspected to be caused by the collapse of the construction frame one of the factors, the previous engineers to design the external wall construction of the wind strength used, mainly reference to the wind-resistant design of our buildings code, The behavior pattern of the force is different from that of the hypothetical structure, which causes the stability and reliability of the wall construction frame outside the design plan to be not ideal, but at any time in the most easyA situation in which a danger of collapse may occur.
In recent years, government units have rewarded urban renewal, and the buildings in the metropolitan area are often refurbished with old houses. In addition, the government departments of responsibility (e.g.: District Labor inspection units, the establishment of regulatory authorities for a long time due to the lack of manpower, can not effectively implement the audit system, the current labour inspection of the majority of people in public works or civil large-scale construction cases of the inspection; The current civil small-scale projects in China (both the appearance of old buildings and repair work), It is just like being allowed to do the works under the rule of no government law, the unsafe operation during the construction period is no time constraint control, so in recent years, scholars in the research literature has often pointed out that the old building in the metropolitan area of the construction project compared to the new project, has a higher risk of collapse
In this paper, the reference values of the ultimate bearing capacity of different concrete strength, different implant depth, different diameters, different anchoring objects and different filler types are measured by drawing test, aiming at the current system of the construction unit which is often used non-standard standard. and through (一) literature review and Data survey collection, (二) On-site visit survey method, (三) experimental comparison method, and other related research methods, to explore the impact of the construction of the wall anchorage of the main factors of ultimate bearing capacity.
This study through the field situation survey, to understand the current situation of the installation of external wall frame construction, and to analyze the results of the drawing test, as the old building skin and repair operations, the construction unit in the current use of non-standard standard of the wall anchor object comparison, The current situation of the use of the anchoring component and the need to conform to the relevant laws and regulations of the bearing capacity gap, in order to achieve the function of disaster prevention and disaster Reduction, the safety of workers ' work safety should be improved and the safety of the management of the construction site should be enhanced by
strengthening or choosing the better suitability.
Looking forward to the results of this experiment, the author thinks the practical suggestions and preventive measures are put forward for the construction of exterior wall frame frame in the current period of skin and repair of old buildings.
