| In recent years,China completed a total construction area of about 2 billion square meters per year,of which more than 600 million square meters of urban residential,a large number of assembled concrete structure.Compared to the complicated construction process,large amount of construction,wet work,the construction speed is slow,the amount of construction waste and serious noise pollution of traditional cast-in-situ concrete structure,precast reinforced concrete structure with construction speed,affected by the weather and seasonal effects of small prefabricated component is convenient for industrial production and construction mechanization,labor saving,save the building materials,construction waste,green environmental protection and improve the building function and structure performance etc..Effective implementation of the "four sections of an environmental protection" green development requirements,to achieve the whole process of the project management of high efficiency,low energy consumption,low emissions of construction process.First of all,based on the characteristics of prefabricated housing,construction of organization and management of the industrialization of residential projects,from the traditional construction of cast-in-place reinforced concrete structure construction experience,the construction organization and construction management of originality in design,construction machinery selection,classification,flow section of water resources investment,construction process,key construction technology has formed the perfect organization construction.At the same time,in-depth study on the key technology of the whole process of production,transportation and storage of precast,hoisting,connection,cast-in-place construction joint treatment,combined with the special lifting,installation,installation of prefabricated components and other equipment,has formed a good construction efficiency of prefabricated housing construction.Secondly,this paper huilongguan,changping district 019 block of prefabricated concrete structure housing project cases,expounds the project prophase planning phase of the total control the network planning design,construction planning,design,process the implementation stage of the key technology and the quality inspection of the completion acceptance stage,etc.Are introduced on emphasis in the process of implementation stage:(1)the project through the use of aluminum alloy template cast-in-situ node,optimized the construction process,realize the one-time casting wall concrete,at the same time of ensuring the quality of perception to shorten the construction period.(2)the project by using the improved reinforcement,ensure the reserved reinforced plane position accurate ensures the perpendicularity of the reinforcement at the same time,improve the efficiency of thecomponents are installed.(3)before lifting the refinement of measurement location and many auxiliary control measures of innovation,fine-tuning measures,to ensure that the component installation are all right,the effective protection of the fabricated structure construction quality.(4)engineering combined with prefabricated prefabricated integration wall thermal insulation system can be directly outside eaves facing construction characteristic,the selection of adhesive lifting scaffolding for outside eaves stereo with construction,save the tower crane crane time,shorten the construction period,saving the cost of construction.Finally,the article to huilongguan,changping district 019 block of prefabricated concrete elements for the prefabricated concrete structure housing in acceptance,installation and construction process to obtain the basis of measurement and control data as the foundation,and the construction quality control measures taken in the construction process,construction standards and the corresponding national standards as the backing,compiled the quality acceptance standard,the quality control of prefabricated housing as the basis.To engineering case at the same time analyze the economic benefit,environmental benefit and social benefit,suggests that the assembled monolithic precast concrete structure construction technology can effectively shorten the construction period,reasonably reduce the comprehensive cost and energy conservation and environmental protection. |
