Analysis on Construction Technology of Thick Slab Transfer Layer With Dark Beam at High Structure
In this paper,taking a large public building as an example,the construction key points of the project with dark beam thick plate transfer layer are analyzed,and the construction scheme of the structure with dark beam thick plate transfer layer is proposed.The results show that the problems of dense reinforcement and difficult installation can be effectively solved by combining reinforcement and segmental construc-tion.When the plate thickness is large,the upper and lower concrete are placed in sequence,which can reduce the pressure of formwork and support;Additional steel mesh and pull hook are set at the joint of the upper and lower parts,which can improve the joint ability of the upper and lower parts of the concrete.Structural cracks can be reduced effectively by optimizing mix ratio,layering pouring and proper maintenance of mass concrete.
