A ring anchor is a horizontal component located in the wall plane that can absorb tensile forces and is used in particular for masonry walls. As a rule, ring anchors are designed as reinforced concrete components. The formwork can be made using a brick ☛ U-shell (lost formwork) or a traditional formwork.
When a slab is designed as a reinforced concrete slab, the reinforced slab edge takes on the function of the ring anchor. (Picture 3)

Ring anchor for brick ceilings
In the case of an alternative design of the ceiling construction as brick ceilings, a circumferential ring anchor is usually required to absorb horizontal load inputs, especially if the stiffening pane effect of the ceiling is not sufficient.
In this case, the ceiling support is designed as a reinforced ring anchor, the static bond takes place via reinforcing bars protruding from the ceiling. Usually, the ring anchor is located in the area of the vertical masonry wall. In the renovation of old buildings, however, it is located at the edge of the ceiling in front of the wall that serves as a support. In order to obtain sufficient space for the concrete to be laid, so-called flat or negative bricks were developed, which are about halved in height.
