BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention is related to the field of wall construction with bricks which interlock horizontally and vertically.

In the field of the present invention, walls have been described that are constructed with bricks having protuberances and cavities which interlock horizontally and vertically with the objective of reducing the use of adhesives or mortar. Bricks with protuberances and cavities which lock horizontally and vertically have also been described with the aim of constructing walls of high lateral resistance to uniform and cyclic forces of nature. However, a system of bricks and rods has not been described for the construction of walls in which the use of adhesive or mortar is reduced, that also results in walls with great lateral rigidity and great resistance to extreme gravitational, cyclic and uniform forces.

2. Description of Prior Art

In the prior art construction of walls have been described using bricks with protuberances and cavities that interlock horizontally and vertically resulting in walls in which the use of adhesive or mortar is reduced, and with high resistance to uniform and cyclic forces of nature.

Specifically, Nanayakkara describes in his patents, U.S. Pat. No. 6,550,208 B2 (Apr. 22, 2003), U.S. Pat. No. 6,105,330 (Aug. 22, 2000), y U.S. Pat. No. 6,578,338 B1 (Jun. 17, 2003), bricks or blocks with a system of horizontal and vertical interlocks, with reduction in the use of mortar, resulting in walls with high lateral resistance to natural uniform and cyclic forces. U.S. Pat. No. 6,550,208 B2 describes a brick having external positive and negative geometries that are complementary, and a continuous vertical cavity, resulting in horizontal and vertical interlocks between adjacent bricks for construction of walls which would have continuous vertical cavities.

However, neither in the prior art nor in the Nanayakkara's patents, there is a description of a brick or block like the one described in the system of brick with rod of the present invention. The brick or block described in Nanayakkara's patents has negative and positive external geometries which are different from the protuberances and cavities of the present invention's brick. Besides, there is no instance of the prior art, which describes a brick with perforations or holes specifically adapted to the diameter of a rod which function is to reinforce the interlocks that are formed by the protuberances and cavities of the horizontally and vertically adjacent bricks of a wall. The system of brick with rod of the present invention allows the construction of walls, as for example, retaining walls, or other kind of walls with great lateral rigidity and great resistance to extreme gravitational, cyclic and uniform forces. The system of brick and rod of the present invention also provides flexible interlocks between horizontally and vertically adjacent bricks for the construction of walls which are less susceptible to fractures in case of seismic movements or earthquakes.

In FIG. 23, it can be observed that the protuberance's base (29) on the lateral surface is of less longitude than the maximum diameter (30) of the convex geometry of the protuberance (28).

The described system of brick and rod allows for the formation of resistant interlocks between horizontally and vertically adjacent bricks to build a wall which permits the introduction of a skeleton constituted by a plurality of rods thus resulting in a structure with great lateral rigidity and great resistance to extreme uniform, cyclic and gravitational forces.

Besides, the system of brick and rod with horizontal protuberances (1) rounded convex, horizontal cavities (2) rounded concave, vertical protuberances (3) rounded cylindrical convex, and rounded cylindrical concave vertical cavities (16), of the present invention, permits the formation of flexible interlocks for the construction of walls less susceptible to fracture formation in case of seismic movements or earthquakes.

FIGS. 22 and 23 show another embodiment of the brick which has a protuberance (28) symmetrical of rounded convex geometry that is originated on one of the lateral surfaces (14) of the brick, wherein the longitude (41) (FIG. 22) of the protuberance defined from the apex (42) of the convex geometry of the protuberance to the base (29) on the lateral surface (14) of the brick, is between 26% and 65% of the width Z of the brick.

In FIG. 25, it is shown that the longitude of the rod is equal or exceeds the longitude of the height of the wall. In the same FIG. 25 it can be observed that the rod can be introduced through the continuous hole that goes throughout the height of the wall.

The continuous holes of the wall which are shown in FIG. 24 can also be used to vertically introduce through the wall, cable lines for electricity, tubes for gas, cable lines for telephones, etc.

FIG. 26 shows another embodiment of the brick of the present invention. In this embodiment, the brick is characterized by a 90 degree right angle channel on the two edges (44), in direction of the Y axis, of the vertical anterior surface (7); a 90 degree right angle on the two edges (45), in direction of the Y axis, of the vertical posterior surface; a 90 degree right angle on the two edges (46), in direction of the X axis, of the superior horizontal surface; and a 90 degree right angle on the two edges (43), in direction of the X axis, of the inferior horizontal surface.

FIG. 27 shows another embodiment of the brick of the present invention. In this embodiment, the brick is characterized by a 90 degree right angle on the two edges (47), in direction of the Y axis, of the vertical anterior surface; and a 90 degree right angle on the two edges (48), in direction of the X axis, of the inferior horizontal surface.

FIGS. 28 and 29 show other embodiments of the brick of the present invention in which the bricks are half in longitude, in direction of the X axis, with respect to other adjacent bricks, in such a way that these bricks are located horizontally at the beginning or at the end of the horizontal lanes of bricks, creating even ends with other vertically adjacent horizontal lanes of bricks, resulting in a wall with a continuous vertical edge.

The rod of the present invention can be a rod (5) made of a single part, or a composed rod comprising rod fragments joined successively.

The rod fragments can be seen in FIG. 1 that shows a tube (5A) which longitude is equal to the brick's height; wherein the tube functions as a female screw; and wherein the tube has an internal thread to screw down a male screw (5B) with external thread. The male screw (5B) is of equal or less longitude than the longitude of the tube (5A). The male screw interlocks internally by its superior half with a tube (5A), and by its inferior half to another tube (5A), forming an interlock of two tubes which would be introduced in two of the vertically adjacent bricks. The composed continuous rod is constituted by successive interlocks formed by a plurality of tubes (5A) and a plurality of male screws (5B).

In another embodiment of the present invention, the composed rod is constituted by rod fragments (26) and (27) (FIGS. 2A and 2B) which longitude is equal to one and a half times (1.5×) the longitude of the brick's height. Each one of these rod fragments, (26) and (27), is formed by three parts defined as first part (49), second part (50) and a third part (51); wherein the three parts have exactly the same longitude in such a way that each part has a longitude equal to one third of the longitude of the rod fragment; wherein the first part (49) is at one end of the rod fragment; and wherein the first part (49) is hollow with internal thread constituting the part that functions as female screw of the rod fragment; and wherein the second part (50) is on the middle of the rod fragment between the first part (49) and the third part (51); and wherein the second part (50) is solid; and wherein the third part (51) is solid with external thread; and wherein the third part (51) is located at the opposed end which constitutes the first part (49); and wherein the third part (51) is the part that functions as male screw of the rod fragment; and wherein the first part (49) of the rod fragment interlocks with a third part (51) of another identical rod fragment, and thus successively a plurality of rod fragments get interlocked to form the composed rod.

One of the advantages of the present invention is the elimination of the use of mortar or adhesives between the horizontally and vertically adjacent bricks in the construction of a wall. This is achieved by interlocks between the protuberances (1) symmetrical of convex geometry which are perfectly complementary to cavities (2) symmetrical of concave geometry of horizontally adjacent bricks, and between protuberances (3) cylindrical-convex that are perfectly complementary to cavities (16) cylindrical-concaves of vertically adjacent bricks.

However, another embodiment of the present invention comprises a brick with a protuberance (3) cylindrical convex that is originated on the superior horizontal surface (6) in such a way that the cylindrical portion forms an angle (52) (FIG. 16) with a slight curved transition with the superior horizontal surface (6); while the cavity (16) cylindrical-concave is originated on the inferior horizontal surface (13) in such a way that the cylindrical portion forms an right angle (53) (FIG. 16) of 90 degrees with the inferior horizontal surface (13). The disparity in the angle (52) formed by the protuberance (1), and the angle (53) formed by the cavity (16) creates an imperfect interlock between vertically adjacent bricks, thus creating a gap of millimeters between vertically adjacent bricks. Said gap can be required by anti-seismic regulations. In case necessary said gap can be filled with mortar.

While the description presents the preferred embodiments of the present invention, additional changes can be made in the form and disposition of the parts without distancing from the basic ideas and principles comprised in the following claims:
