Formwork structure for shear wall at deformation joint and construction method

ZHANG NANNAN

A shear wall formwork structure for a deformation joint comprises a deformation joint inner side formwork system and a deformation joint outer side formwork system, and is characterized in that the deformation joint inner side formwork system comprises a panel, square timber and a steel pipe, and the deformation joint outer side formwork system comprises a panel, square timber and a steel pipe; a square steel plate is fixedly welded to the end of a screw on the inner side of the first split bolt fixing piece, and the outer side of the first split bolt fixing piece is fastened through double nuts. An assembly is arranged at one end of the second split bolt fixing piece, the assembly is formed by fixedly welding the inner side and the outer side of an E-shaped buckle with double steel pipes and a nut respectively, and a sleeve is arranged in a screw of the second split bolt fixing piece. The shear wall formwork structure for the deformation joint and the construction method have the advantages that the occupied space of formwork supports is reduced, formworks on the two sides of the deformation joint can be constructed at the same time, the project progress is accelerated, the formwork turnover rate is increased, the quality is improved, and the project cost is reduced.

一种用于变形缝处剪力墙模板结构，包括变形缝内侧模板系统、变形缝外侧模板系统，其特征在于：所述变形缝内侧模板系统包括面板、方木、钢管，所述变形缝外侧模板系统包括面板、方木、钢管，其中所述第1对拉螺栓固定件的内侧螺杆端部固焊方形钢板，外侧用双螺帽紧固；所述第2对拉螺栓固定件的一端设有组合件，组合件为山形卡扣内外侧分别与双钢管及螺帽固焊，第2对拉螺栓固定件的螺杆中设有套管。本发明的用于变形缝处剪力墙模板结构及施工方法具有减小了模板支撑的占用空间，变形缝两侧模板可同时施工加快了工程进度、提高模板周转率，提高质量和降低工程成本的优点。
