Abstract
Description
- 1. Field of the Invention
- This invention relates to a building component for application in the construction industry. More specifically, the invention applies to a building component that has particular application to the construction of low-cost housing structures and any other types of structures.
- 2. Description of Related Art
- The use of inter-locking block components for the purposes of building houses, particularly low cost housing structures, is well known. There are, however, well documented difficulties associated with existing interlocking block systems.
- One known difficulty concerns the fact that the majority of blocks used in these systems are solid structures. Accordingly, the blocks are heavier, more difficult to work with and more expensive due to the need to use more building material in their manufacture. Furthermore, in known systems, at least a small amount of paste substance is still required to stabilise wall structures built using these interlocking block components.
- A further difficulty associated with known interlocking block systems is that they usually require at least two different block configurations in order to build a wall structure. Furthermore, although many interlocking building systems are intended for the so-called “owner-builder” market, a relatively high level of skill is nevertheless still required in the proper laying of the building components in order to safely construct wall structures. This is partly due to the fact that there are a number of possible ways in which two blocks may be inter-connected and the builder is required to determine the most effective manner of laying them. A still further problem associated with existing interlocking block systems is that the interlocking structures do not slide into place easily and must often be manually manipulated, sometimes requiring force, in order to secure them in position.
- It is an object of this invention to provide an interlocking building component that has advantages over many prior art arrangements.
- In accordance with one aspect of this invention there is provided an interlocking building component in which the building component comprises a generally rectangular main body having operatively top and bottom surfaces and in which the generally top surface has one or more upwardly extending projections and the operatively bottom surface includes recesses adapted and positioned to receive the projections of a like component in an operatively stacked arrangement.
- Further features of the invention provide for the building component to have two opposing lateral and end walls respectively; for the building component to preferably be hollow defining an outer peripheral edge and having at least one central dividing wall; for the building component to preferably be manufactured from concrete or a similar material; for the projections to preferably be of a generally rectangular configuration; for there to be at least two projections on each opposing lateral peripheral edge and at least one projection on each opposing end wall edge; for there to preferably be one projection extending from the peripheral edge of the dividing wall; for the projections of the dividing and end walls to be generally centrally positioned and for the three projections to be co-linear; for the two projections of each lateral wall to be spaced apart and towards generally outer edges of the lateral wall and to be positioned directly opposite the projections on the opposing lateral wall; for the projections to be relatively shallow; for the recesses of the operatively bottom surface to be located in co-linear arrangement with the projections of the operatively top surface; for the recesses of the outer lateral and side walls to be exact impressions of the projections.
- In order that the above and other features of the invention may be more fully understood one embodiment thereof will now be described with reference to the accompanying drawings, wherein:
-
FIG. 1 is a perspective view of the building component of the present invention, showing the top portion thereof; -
FIG. 2 is a perspective view of the building component of the present invention, showing the bottom portion thereof; -
FIG. 3 is a side elevational view of the building component; -
FIG. 4 is a top plan view of the building component; -
FIG. 5 is a front elevational view of the building component; and -
FIG. 6 is a perspective view of a plurality of building components in assembled condition to form a wall. - In the embodiment of the invention generally illustrated in
FIGS. 1-5 of the drawings, an interlocking building component orblock 10 comprises a generally rectangularmain body 12 comprising a pair of opposinglateral walls 14 and a pair ofopposing end walls 16 and in which thebody 12 has an operativelytop surface 18 and an operativelybottom surface 20. - The
rectangular body 12 of the building component is preferably hollow defining a peripheralouter edge 22 and having a dividingcentral wall 24 in order to create two halves of equal dimensions. In a preferred embodiment of the invention, there are at least two spaced apart generally upwardly extendingprojections 26 on the upper peripheral edges of the two opposinglateral walls 14. Theprojections 26 on opposinglateral walls 14 are co-linear. A further pair ofco-linear projections 28 is provided on the upper edges ofopposing end walls 16 with theprojections 28 being centrally located along the peripheral edges of theend walls 16. Afurther projection 30 is provided on the upper edge of the central dividingwall 24 which is also co-linear with theprojections 28 of the twoend walls 16. Theprojections -
Recesses bottom surface 20 of themain body 12. Therecesses projections similar block 10 in a stacked arrangement during building operations. Therecesses end walls corresponding projections projection top surface 18 is co-linear with arecess bottom surface 20. The recess on the bottom edge of the central dividingwall 24 is not, however, an exact impression of its corresponding projection and is, instead, more in the nature of an elongate groove or opening 36 between the lower portions of the opposinglateral walls 14. - The
building component 10 of the invention is intended to be stacked together with like building components in a vertical arrangement in order to build walls or the like. In the stacked arrangement of the wall W, illustrated inFIG. 6 of the drawings, theprojections component 10 slot or slide into thecorresponding recesses FIG. 6 . Further in this connection, the ability to lay the components in this manner facilitates the building of corners between two walls, as also shown inFIG. 6 . Thecentral groove 36 on the operativelybottom surface 20 facilitates the stacking of the building components in the manner described above, in that it receives therein theprojection 30 on the central dividingwall 24 of the adjacent component. - Further in accordance with this invention, the positioning of the
projections corresponding recesses components 10 as there are limited ways in which the components may be interlocked. The result is that fewer construction errors are made and less skill is required to lay the components. Also, the fact that theprojections recesses - A further advantage of the interlocking
building components 10 is that they allow for a mortarless wall assembly. The building components allow for a completely dry interlocking and stackable system as no paste in the form of cement, plaster or the like is required to stabilise a wall structure resulting therefrom. - It will be understood that the invention provides an extremely simple yet highly effective interlocking building component that has wide application potential depending on requirements. Also, numerous variations may be made to the embodiment of the invention described above without departing from the scope hereof.
