Prefabricated shear wall structure wallboard on-site construction method in hot-summer and warm-winter area
The invention provides a prefabricated shear wall structure wallboard on-site construction method in a hot-summer and warm-winter area. The construction method includes the steps that a BIM and an integrated design mode are matched, an upper-layer prefabricated wall of a conversion part is lofted firstly, and the upper-layer prefabricated wall is mounted by controlling the positioning precision of a lower-layer cast-in-place wall reinforcing steel bar of the conversion part through three-time rechecking of reserved reinforcing steel bar positioning; after the wall is hoisted in place, a long wall is subjected to bin dividing treatment, a horizontal seam is divided into two bins through base slurry, and the horizontal seam is blocked through C-shaped steel, foam cotton and expansion bolts before grouting is conducted on the outer side of an outer wall; and the inner side of the outer wall and an inner wall use plastic angle beads, the fullness of the plastic angle beads is checked through an observation hole sleeve after cement mortar is plugged outside the plastic angle beads, and if part of air in a bottom bin falls back due to emptying of grout, supplementary filling should be conducted in time. According to the prefabricated shear wall structure wallboard on-site construction method in the hot-summer and warm-winter area, the problem of steel bar positioning at the conversion part is solved, plugging of the inner side and the outer side of a single-layer wallboard is completed under the condition that the cross section of the wall is not damaged, checking and compensating measures are effective, simple and convenient, and social benefits are remarkable.
本发明提供了一种夏热冬暖地区装配式剪力墙结构墙板现场施工方法，配合BIM及一体化设计方式，先将转换部位上层预制墙体放样，通过三次复核预留钢筋定位，控制转换部位下层现浇墙体钢筋定位精度，完成上层预制墙体安装；墙体吊装就位后，对较长墙体分仓处理，利用座浆料将水平缝分为两仓，外墙外侧灌浆前用C型钢、泡沫棉和膨胀螺栓对水平缝进行封堵；外墙内侧及内墙使用塑料角条，在塑料角条外用水泥砂浆封堵后通过观察孔套筒检查饱满度，若浆液因排空底仓空气有部分回落，应及时补灌。本发明解决了转换部位钢筋定位的难题，且在不损失墙体截面的条件下完成了单层墙板内、外侧封堵，检查补偿措施有效、简便，社会效益较为显著。
