全预制装配整体式剪力墙结构构件工厂化生产技术

Factory Production Technology for Components of the New Precast Concrete Shear Wall Structure

全预制装配整体式剪力墙结构(NPC)剪力墙、柱、电梯井、阳台、空调板、雨篷等构件采用工厂化预制生产,预留注浆管及节点钢筋;梁、板等水平构件采用工厂化预制生产叠合梁、板,预留上层钢筋及端部节点钢筋。通过现场吊装、注浆管浆锚及节点现浇形成整体结构体系。阐述了该体系构件工厂化生产的施工工艺和注意事项。重点介绍了台模加工与安装、钢筋与注浆管加工、钢筋骨架及网片绑扎、注浆管及安装预留预埋、混凝土浇筑等施工工艺。

The components of shear wall, column, elevator shaft, balcony, air conditioning board and canopy in the new precast concrete shear wall structure are prefabricated in factory,in which grouting pipe and joint steel bars are reserved. In addition, the horizontal components such as beam and slab are also prefabricated in factory into composite beams and slabs, in which upper and ending joint steel bars are reserved. Through hoisting on site, cast-in-situ concrete of slurry and anchor joint, the structure is formed integral system. The construction technology and points for attention of components processing in factory are indicated. The processing and installation of bench formwork, processing of steel bars and grouting pipe, binding of steel bars skeleton and network, reservation and embedding of grouting pipe and installation, concrete pouring are introduced in detail.
