摘要: 针对套筒连接的装配式剪力墙施工工序复杂、建造效率低、质量不易保证问题,基于等强设计原则,提出了一种新型竖向分布钢筋不连接装配整体式剪力墙结构体系(SGBL 装配整体式剪力墙结构). 该体系预制墙体竖向分布钢筋断开,采用坐浆连接方式,两侧现浇边缘构件配筋相应加大. 详细介绍了该体系的特点以及相应的“设计、生产、施工”一体化建造模式,围绕示范工程,采用数值分析等方法对该体系的抗震性能进行对比分析,结果表明 SGBL 装配整体式剪力墙结构体系抗震性能与套筒灌浆剪力墙结构体系相当,坐浆工艺可靠,结构成本降低6. 5%,每片预制墙体安装时间节约 15min,平均施工效率提高约 25%,综合效益显著,取得了良好的示范效果.

Abstract:According to the problems of complex construction procedures, low construction efficiency and difficult qualityassurance of sleeve-connected assembled concrete shear wall structure, based on the principle of equal-strength design, anew type of monolithic assembled concrete shear wall structure with non-connected vertical distribution reinforcement(SGBL assembly shear wall structure) was proposed. The vertical distributed reinforcement was disconnected of theassembly walls and cement-based grouts connection was applied. Correspondingly, the reinforcements of the cast-in-situboundary element on both sides were enlarged. The characteristics as well as the integrated construction mode of “design,production and construction” were introduced in detail on the structural system. Based on the demonstration project, theseismic performance of the system was compared by numerical analysis. The results show that the seismic performance ofthe SGBL monolithic assembly shear wall structure is equivalent to that of the grout-filled coupling sleeve shear wallstructural system, cement-based grouts connection is reliable and the structure cost is reduced by 6. 5%. The installationtime of the assembly wall was saved by 15 minutes, and construction efficiency is increased by about 25% averagely, andthe comprehensive benefit is obvious and good demonstration effects have been achieved.
