Abstract: The invention comprises a folding pyramidal structure in which one or several people can be introduced, being designed to bear extreme loads derived from collapsing of the building provoked by large intensity seismic waves.

In case of failure of the building during a large intensity earthquake, the niches formed with the help of this structure may avoid death of its occupants.

Abstract: A load bearing structure having a set of uniform voids functions to resolve the forces imposed by developing compression in the material having the voids and minimizing the amount of tension developed in the material. The voids are deployed to encompass a matrix of points arranged such that each point is spaced an equal distance from twelve and only twelve adjacent matrix points. If the structure is considered to be composed of a closely packed set of hypothetical rhombic dodecahedra (RD) and the four-edge vertices of each of those hypothetical RDs is truncated, the result will be a set of cubic voids. The center of each of those cubic voids will define the matrix referred to above and the cubic voids will serve to provide the optimum resolution of stress which minimizes the development of tension in the material. One in four of the hypothetical RDs can be eliminated achieving the same force resolution in a structure containing less material.

The tiles can be converted to 3-dimensional space-filling blocks. When these blocks are hollow and inter-connected, architectural environments are possible.

Abstract: A load bearing structure having a set of uniform voids functions to resolve the forces imposed by developing compression in the material having the voids and minimizing the amount of tension developed in the material. For the voids to have this function, they must be deployed in a particular fashion. The voids are deployed to encompass a particular set of points. The set of points are such that each point in the matrix is spaced an equal distance from twelve and only twelve adjacent points of the matrix. The distance between the points does not matter as long as all are uniformly distanced in accordance with that rule. If the structure is considered to be composed of a closely packed set of hypothetical rhombic dodecahedra (RD) and the four edge vertices of each of those hypothetical RDs is truncated, the result will be a set of cubic voids.

Many of these connectors and rods may be assembled to form larger structures such as cubes, pyramids and other polyhedrons. The connectors themselves may take various shapes such as triangles, sectors and trapezoids.

Abstract: In the case of a known multiple-layer space-framing plate of rods and gusseted joints, which consists of a plurality of circular meshwork arrangements which are connected with one another, which extend as a honeycomb in a space, the circular meshworks define hollow spaces which are open to the outside, in the area of which no brackets are present for attachment of roofing or side wall coverings.
