A cross-shaped structure with vertical walls branching out from the center in all directions.
A square silo is constructed by joining PC walls vertically and horizontally, but the vertical and horizontal cross-shaped PC walls are joined from the opposing surfaces of the wall plates of the opposing PC walls. Weld the protruding horizontal reinforcing bars with reinforcement bars,
This is done by placing connecting concrete between both wall slabs to transmit in-plane and out-of-plane forces, and the joints between vertically adjacent cross-shaped walls are made by placing connecting concrete between the same wall slabs. This is done by interposing non-contraction mortar and connecting the upper end protrusion of the vertical reinforcement of the lower wall slab to the vertical reinforcement of the upper wall slab via a splice sleeve, thereby reducing the horizontal force in the in-plane direction. This is transmitted by the strength of the attached reinforcements between the PC wall and the mortar and the vertical reinforcements.
