摘要

PPROBLEM TO BE SOLVED: To allow a single worker to efficiently carry out manhole stacking work even if a shaft area in which a manhole is constructed does not have a sufficient size for carrying out the work. PSOLUTION: There is provided a connection fitting for connecting between upper and lower blocks which are stacked on each other to constitute the manhole and have the same external diameter. The connecting fitting is a combination between a receiving member and a second fit-in plate. The receiving member has a guide piece formed at a longitudinally uppermost end, and an insertion portion which has a stopper sliding hole formed therein at a location under the guide piece, and a mounting hole formed in a lower end thereof. The second fit-in plate has a fit-in portion having a width narrower than that of the insertion portion. The fit-in portion has a mounting hole formed in an upper end thereof, and a stopper formed on a lower end thereof, which slides in the stopper sliding hole through a predetermined height so as to allow upper and lower connection portions of the respective blocks to separate from each other by a predetermined distance, when an impact such as an earthquake occurs.

要解决的问题：即使建造人孔的井道面积不足以进行作业，也允许一个工人有效地进行人孔堆叠工作。

解决方案：提供了一种连接配件，用于连接上下堆叠在一起的上，下块，以构成人孔并具有相同的外径。连接配件是接收构件和第二装配板之间的组合。接收构件具有在其纵向的最上端处形成的引导件，以及在该引导件下方的位置处形成有在其中的止动件滑动孔的插入部以及在其下端形成的安装孔。第二装配板具有装配部，该装配部的宽度比插入部的宽度窄。装配部在其上端形成有安装孔，在其下端形成有止动件，该止动件在止动件滑动孔中滑动预定高度，以允许各个块的上下连接部。当发生诸如地震之类的冲击时，它们彼此分开预定距离。
