Study On Comprehensive Construction Technology Of Outer Canopy Of High-grade Residential Building

With the domestic construction market for many years of rapid growth and development,the construction industry has become a pillar industry of the national economy,as the main carrier of the construction economy,residential building prices gradually rose,the majority of large urban core city gradually into the luxury era,The quality,style,function and construction quality of the new residential building are correspondingly higher and higher,and lots of high-grade residential buildings are correspondingly born,and a large number of new construction technologies have also appeared.As the most direct external quality of the building,the eaves of the residential building become the focus of the owners,design and society.As a building construction practitioner,we want to hear people see the construction of the building,you can say: "The building is the quality of the building," such as a positive evaluation,and look forward to the negative evaluation gradually reduced and disappeared.In this paper,a residential building in Beijing as the main carrier.As residential location is relatively high-end,modern,high-end residential sales in order to meet the requirements of residential residential building facade modeling complex and varied,so the eave project application of new technologies,especially in the application of more energy-saving new technology.Engineering eaves height of 82.7 meters,the outer wall of the following four dry stone curtain wall,four to twenty-eight layer of the balcony glass curtain wall,the other parts of the decorative brick,external wall insulation using graphite polystyrene board installed glass micro The fire-proof isolation belt,the decorative pilaster for the "back"-shaped structure of the outer wall column,the roof of the integrated use of waterproof insulation technology,steel structure flower decoration,GRC modeling column,construction technology there are certain difficulties,the need for appropriate research and solution.The main topic of the project is to study and analyze the various problems in the eaves of the first and second stage of the plot,such as how to ensure the building fireproofing and thermal insulation performance as well as better economy;When the wall column structure construction,if the internal use of wood mold time,wood mold can not be removed,resulting in waste of materials,and construction efficiency at the end,if pilasters internal pouring concrete,the cost is higher,and self-weight is not conducive to structural safety;In addition to the curtain wall outside the window water leakage problem has been the focus of community complaints,especially in the main box and the deputy between the box,the traditional practice with foam plastic or mortar block,poor durability and easy water leakage;in roofing,the previous practice in the insulation The layer is easy to keep water,and the roof floral and other structures are more,become the roof leakage.In view of the problems in the past,the subject of the study of the facade of the building and the roof of the eaves of the construction of the new technologies used.In the facade,the main use of graphite polystyrene board to install fire isolation zone,"back" shaped wall column wall construction technology,the new curtain wall waterproof structure,the roof roof waterproof insulation integration technology.Graphite polystyrene board installation of fire isolation with the construction technology to ensure the fire and insulation properties under the premise of a significant reduction in cost,there are very good economy,the current application of this technology is not much,the construction unit is the first time Application of this technology,there are very good prospects and application of the promotion of value for other units to provide a reference."Hui" shape wall wall column construction of new technology,with graphite polystyrene board as the template to replace the original design of the wood formwork,eliminating the need for mold-mode part,a significant savings in duration and cost,and can improve Building insulation properties.In the outer curtain wall sealing,the construction unit optimization design,through the installation of water-stop steel,sealing glue to solve the outer wall leakage problem.The integration of roof waterproof and thermal insulation uses hydrophobic expanded perlite insulation mortar waterproof layer of new technology,making both insulation and waterproof insulation layer to solve the traditional insulation layer is easy to keep water,and ultimately through the concrete roof leakage And the use of artificial turf in the roof,so you can ensure that the four seasons evergreen,enhance the perception and low cost,low maintenance costs later.Artificial turf and SF polymer waterproof mortar common use after the actual test results are good,in the perception and waterproof insulation performance to the owner’s approval.Area III project has also made Beijing model of safe and civilized construction site,the Great Wall of Beijing Gold Cup structure,the Great Wall Cup Silver Award.In addition,the curtain wall waterproof structure and the "back" shape wall wall column construction of new technology patents are accepted.
