An architectural design office in Spain recently developed an innovative construction structure that can save building space and materials to the greatest extent. This set of tic-tac-toe grids with holes on all sides and hollows The building structure can be used to install various water and electricity pipes, making full use of the space within the floor and greatly reducing the load on the ceiling. According to surveys, the height of the 6-story building built using this new structure is equivalent to the height of the original 5-story building, and each floor can save 30 to 50CM in thickness. It looks like a hollow cement board structure, but its actual load-bearing capacity is no less than that of a solid wall. It is an ideal structural choice when building long-span buildings.
