摘　　要：随着装配式建筑的普及和发展,大量新型装配式建筑墙体材料涌入建材市场,针对不同特点的工程项目,应选用不同的建筑墙体材料。本文以南开大学津南校区学生公寓10号楼项目为例,根据总工期、场地条件、结构形式、埋墙箱体管线及二次结构施工时间节点等情况,对CT快装式高精度脱硫石膏轻质砌块施工技术及应用优势进行了研究。工程实践证明:通过结合砌块自带榫头和榫槽的相互咬合、专用石膏胶浆黏结的干法施工以及埋墙箱体管线与砌墙同步实施的特点,加强了二次结构砌筑墙体的整体性和稳定性,提高了施工效率,降低了对作业环境温度的要求,减少了后期墙面饰面层出现空鼓、开裂等隐患,同时该砌块还可计入装配式分值计算。本文成果可为同类项目提供一点参考。With the popularity and development of prefabricated buildings,a large number of new prefabricated building wall materials have flooded into the building materials market,and different building wall materials should be selected for different projects with different characteristics.In this paper,the student apartment building 10 at Nankai University Jinnan District was taken as an example,the construction technology and application advantages of CT quick-loading high precision desulfurized gypsum lightweight block were studied,according to the overall construction period,site conditions,structural form,embedded wall box pipeline,and the construction time node of the secondary structure wall.Engineering practice proves that by combining the interlocking of of the tenon and mortise of the block,dry construction using specialized gypsum adhesive for bonding,and synchronously implementing concealed pipe and wire installation in wall boxes when bricklaying,the integrity and stability of the secondary structure wall,were enhanced construction efficiency was improved,the temperature requirements for the work environment,and the hidden dangers such as hollowing and cracking that may occur in the later stages of wall surface finishing were reduced.Additionally,this type of block can also be included in prefabricated construction calculation.The results of this paper can provide some reference for similar projects.
