Study On Quality Problems Of Concrete Prefabricated Components In W Company

The implementation of the construction industry modernization,the development of assembly-style buildings is to change the construction mode of construction,promote industrial transformation and upgrading,to achieve sustainable development of the important initiatives.With the further promotion of assembly buildings,the quality of concrete prefabricated components has become a concern.The company of the W is a concrete concrete prefabricated component manufacturer,mainly produces prefabricated concrete wall panels and prefabricated concrete laminates.The quality of concrete prefabricated components is one of the most important problems affecting the development of the company.Therefore,the quality of concrete precast the focus of the study.First of all,through on-site research and analysis of the actual situation of the production of prefabricated concrete parts of the company,to collect weekly production meetings,quality seminars,production quality weekly,production quality monthly reports,after-sales service orders,quality feedback table and other data,Prefabricated component quality problems are classified to sum up the prefabricated wall panels honeycomb,linen,prefabricated laminated panels missing edges and other issues,secondly,based on the above problems,with the quality management tools-fish bone map,from the human,machine,material,law,ring five angles analysis,analysis of the staff training system is not perfect,vibrant,fabric unreasonable product quality factors The In order to determine the causes of quality problems,the questionnaire was designed from the aspects of personnel,equipment,method,material supply,environment and so on.The main objects of the questionnaire wereconcrete prefabricated components.Personnel,and assembly site personnel.Based on the statistical analysis of the results of the questionnaire,the analysis of the personnel and the production process is the main reason for the quality of the problem,for the cause of product quality problems,the use of "5W1H" and "ECRS" analysis of personnel and production processes to improve.Finally,the improvement plan,for the staff process operation is not in place,put forward the perfect training system,the establishment of reward and punishment system,the staff on a regular basis to assess the introduction of anti-error method and other programs;for production reasons,should improve the mold cleaning process,Mold assembly process,concrete mixing process,concrete fabric process and other production processes,proposed the establishment of standard operating instructions and other improvement programs.Through the study of product quality problems,it can provide decision-making reference for enterprises to improve the production standard of concrete prefabricated components,provide suggestions for enterprises to improve product quality continuously,and promote the healthy development of concrete prefabricated parts industry in our province.
