Three-dimensional construction element comprising a body of generally polyhedral form
| Details |
Inventors: Polack, Andre M.;
Assignee: Matrapa S.A. (Geneva, CH)
Primary Examiner: Perham; Alfred C.
Assistant Examiner:
Attorney, Agent or Firm: Miller & Prestia
A three-dimensional construction element comprising a body of generally polyhedral form with an aperture therethrough. Said element comprises at least one peripheral rib forming a statically indeterminate frame the neutral axis of which is located in a plane parallel to the planes defining the ends of the element having the aperture therethrough, and in that the grooves located beside the rib form, separately or together, a geometric figure which is complementary to the figure formed by the rib. (FIG. 1). |

DETAILED DESCRIPTION I claim: 1.
A three-dimensional construction element comprising a body of generally polyhedral form with an aperture therethrough, characterized in that it comprises at least one peripheral rib forming a closed frame, the sides of said rib and the corners of said element are bevelled, and in that grooves located beside the rib form, separately or together, a geometric figure which is complementary to the figure formed by the rib thereby providing for the engagement of another complementary rib therein.
2.
The construction element in accordance with claim 1, wherein said frame having a neutral axis located in a plane parallel to the planes defining the ends of said element having the aperture therethrough and the plane of the neutral axis of the frame formed by the peripheral rib is a median plane of the element.
3.
The construction element according to claim 1, comprising several ribs, characterized in that the ribs are separated by grooves the shape and dimension of which are the same as those of the ribs, in such a way that two adjacent elements can be interlocked with one another, being staggered by the width of a rib.
4.
A process of mortar-less building utilizing several elements according to claim 1, comprising placing said elements in a juxtaposed or superimposed position in such a way that the ribs of each element engae the grooves of an adjacent element and that the corners of each element engage corners of the adjacent ones.
5.
The construction element as claimed in claim 1, forming a parallelepipedal cell, characterized in that the small side of the parallelepiped is between 1.
5 and 3.
5 meters long and corresponds to the height of the dwelling unit.
6.
The construction element as claimed in claim 1, characterized in that it comprises means to enable wheels to be fitted with a view to transporting it by road.
7.
The construction element according to claim 1, characterized in that it comprises at each end a set of wheels for transporting it by road and a lifting apparatus, so as to permit the element to be loaded and unloaded automatically
