The Split Technology And Connection Method Of Precast Concrete Frame Structure

Monolithic precast concrete shear wall structure is constructed monolithic concrete structure with a whole part of the precast shear wall,referred to as shear assembly monolithic structure.It has faster building,the advantages of unrestricted by weather conditions,labor saving and improved construction quality.To overcome the shortcomings of the current domestic prefabricated shear wall system,Five standard components have been proposed during Liaoning Yuhui Co.,Ltd during one-year internship.According to specifications given of the connection,several connections have been proposed.And Several tests have been conducted of dry-wall connections.Abaqus finite analysis software has been analyzes the use of lap length coat spiral stirrup to allows indirect lap reduced 1.61ae from 1.21ae.Standard components for the proposed deepening design,including design and rings hanging point design.According to the actual design of the support frame of a transport situation in the transport component.(1)Five standardized components have been proposed and lateral and vertical splitting scheme have been proposed.This scheme has been applied to the current domestic split several affordable housing projects:Shenyang metro Huimin rental projects,Shenyang Metro Huisheng public rental projects,Shanghai Pudong New Area folk affordable housing projects.Through the use of this comparison,the new scheme can greatly reduce the number of split components,greatly reducing the preliminary design staff workload,improve work efficiency,and infrastructure to ensure the accuracy of the key parts of the structure greatly reduces field installation procedures,etc.(2)This article describes the vertical connection splitting scheme adopted:Constraint pulp anchor lap joint,cast with(spiral stirrups)connection and dry connection,and experimental verification in the form of dry-type connection through anti-shear performance.(3)The use of finite element analysis software ABAQUS analysis using coat spiral stirrup can reduce the length of reinforced steel indirect connection lap,lap length to verify the actual project will be reduced by 1.61ae 1.21ae of rationality.(4)The standard components deepening design,design elements include hanging points and lifting rings design.Transportation for members designed a brace.
