Accurate positioning type concrete hollow block

The utility model relates to an accurate positioning type concrete hollow block comprising a hollow brick body, wherein a partition plate is arranged in the brick body to divide the interior of the brick body into two adjacent hollow cavities. The accurate positioning type concrete hollow block is characterized in that connecting iron elements for positioning and connecting are respectively arranged at the top of the partition plate and the bottom of the brick body, the connecting iron element at the top of the partition plate is fixed at the central point of the two left and right side edges of the partition plate, and the connecting iron element at the bottom of the brick body is fixed at the central point of the bottom surfaces of the inner walls of the two left and right side walls of the brick body. The accurate positioning type concrete hollow block provided by the utility model has the beneficial effects that since the connecting iron elements for positioning and connecting are respectively arranged at the top of the partition plate and the bottom of the brick body, when the connecting iron elements of two upper and lower layers of building blocks are positioned in a stagger manner, the connecting iron elements are welded and positioned to achieve the accurate positioning of the building blocks, so that the accurate positioning of the building blocks can be achieved and the working efficiency can be improved.
