Integral prefabricated concrete elevator shaft
The invention discloses an integral prefabricated concrete elevator shaft which comprises a plurality of cylinders which are vertically lapped and spliced, bolt connecting steel bars with the upper ends extending outwards are pre-buried in the cylinders, bolt connecting grooves are formed in the lower ends of the cylinders, and the bolt connecting steel bars of the cylinders on the lower layer are inserted into the bolt connecting grooves of the cylinders on the upper layer. The bolt connecting steel bars are fixedly connected in the bolt connecting grooves. The integral prefabricated concrete elevator shaft is integrally formed, compared with a prefabricated stacked elevator shaft, the on-site installation steps are reduced, and the installation precision is higher. A bolt connection method is adopted for barrel connection, the use of a sleeve is avoided, the method can guarantee the integrity of components, production and installation are easy and convenient, the detection mode is simple, convenient and reliable, on-site wet operation is reduced, the construction efficiency is improved, the connection cost is reduced, the comprehensive economic benefits are improved, and the environmental protection requirement is met.
本发明公开了一种整体式预制混凝土电梯井，包括上下搭和拼接的多个筒体，所述筒体内预埋有上端向外延伸的螺栓连接钢筋，该筒体的下端设置有螺栓连接槽，下层所述筒体的螺栓连接钢筋插入到上层所述筒体的螺栓连接槽内，且所述螺栓连接钢筋固接在所述螺栓连接槽内。本发明的整体式预制混凝土电梯井一体化成型，相较于预制层叠式电梯井减少了现场的安装步骤，安装精度更高；筒体连接采用螺栓连接方法，避免了套筒的使用，该方法能够保证构件的整体性，生产安装简便，检测方式简便可靠，减少了现场湿作业，提高了施工效率，降低了连接成本，提高了综合经济效益，符合环境保护要求。
