A METHOD TO CONSTRUCT LIGHTWEIGHT SLABS AND PRE-FAB SLABS WITH SPHERES AND UNFOLD-ABLE THREE DIMENSIONAL SET TECHNICAL FIELD

摘要

Having thus particularly described and identified the nature of this invention and how it must be implemented, we hereby claim ownership and exclusive right: 1 - A method to construct lightweight slabs and pre-fab slabs with spheres and a unfold-able three-dimensional set comprising the following steps: Step I: To prepare a formwork or mold on-site Step 2: To place the unfold-able three-dimensional set on the formwork or mold. Which consists of an upper orthogonal steel mesh welded or tied with wire, forming a grid whose dimensions depend on the diameter of the spheres and span of the slabs or pre¬fab slabs, a lower orthogonal steel mesh welded or tied with wire, forming a grid whose dimensions depend on the diameter of the spheres and span of the slabs or pre-fab slabs, forming a grid whose dimensions also depend on the diameter of the spheres and and span of the slabs or pre-fab slabs; the joints between the two steel meshes are hinge-type unions placed in such a way as to create room for the spheres. This forms the frame structure that can be folded or unfolded. The rigidity of the three-dimensional set is achieved by the forces from the spheres that tend to separate them and the spacers that tend to join them. Step 3: Once deployed or unfolded, the three-dimensional set contains spaces provided for the plastic spheres made of plastic or other recycled materials Step 4: After this, the concreting is done until the spheres are completed concealed within the slab"s thickness.
