Abstract

A framework block or brick consisting of modular elements of formed sheet steel or aluminum and having the shape of a rectangular parallelepiped comprising: two identical, pyramid-shaped elements symmetrically disposed and composed each of a rectangular base frame defining the facing surface of the walls and corner elements or ribs forming the four opposite semidiagonals of the brick which are connected to the corners of the base frame, and four angle bars having substantially a C-section and connected to the corners of the respective base frame and provided with holes for the connection of the blocks to one another by fastening means. The elements or ribs intersect in a flattened central portion provided with holes for the connection of said ribs and the elements to one another by fastening means.

Claims

1. A framework block or brick of sheet steel or aluminum which is press formed, which has the shape of a rectangular parallelepiped, which is of a modular framework structure, and which is formed by elements placed along the corners and the diagonals of the parallelepiped, comprising:

(a) two identical component elements having the shape of rectangular pyramids disposed with opposite vertices and the bases of which are the external facing surfaces of the block or brick; and

(b) four angle bars having a C-cross section and forming the corners perpendicular to the external facing surfaces,

wherein each of said component elements includes a base frame and two V-shaped elements or ribs which form the corners of the pyramid and extend and intersect such that each V-shaped element forms a pair of opposite semidiagonals having a first flattened end for connection to the base frame at the corners thereof and a second flattened end corresponding to the vertex of the pyramid for connection to each other, the connections being made by fastening means.

2. The framework block or brick according to claim 1, wherein said base frame comprises:

(a) an overturned U-section having a first, central band defining the facing surface of the brick;

(b) a second, external longitudinal band and a third, internal longitudinal band both at right angles with the first band, the third, internal band having a length less than the second, external band.

3. The framework block or brick according to claim 1, wherein each of said angle bars comprises:

two longitudinal flanges extending with edge portions which are parallel to said flanges but offset inwardly, and

wherein longitudinal cuts are provided in the transit regions of each angle bar between said flanges and their edge portions, said cuts having a depth at least the same as the width of said third external band of said base frame, said edge portions extending at the upper and the lower sides with tabs, each of which are bent at right angles inwardly and are provided with a hole designed to align with a corresponding hole in said first, central band of the base frame and to receive the fastening means to secure said angle bars to the base frame.

4. The framework block or brick according to claim 1, wherein holes are formed longitudinally at predetermined distances along said flanges of said angle bars in order to receive the fastening means to secure the blocks to one another.

5. The framework block or brick according to claim 1, wherein formed covering plates are provided to cover and to shield the joint regions among the bricks and to join the corner regions of the bricks, said plates being formed so as to follow the contour of the corner regions among the connected bricks and being provided with folded edges for retaining the connected bricks and with holes coaxial with the holes formed in the underlying base frame.
