Abstract
Description
- The present invention relates to construction materials and methods, and more particularly to a multi-directional, interlocking, hollow modular building element designed to increase stability of load-bearing walls or structures and minimize active pressure.
- In building of load-bearing constructions involving filling materials, such as supporting walls, dams and artificial islands, the active vertical and horizontal pressure of the filling material must be taken into consideration. The width of the slope needed to absorb the active pressure exerted by the filling material is proportional to the height of the filling material.
- In order to absorb active pressure and to prevent slippage, sinkage etc. of load-bearing constructions, various methods are used, such as rock terraces, or thick, heavy, retaining walls. These methods generally require the use of a large amount of building material, ground area and area of foundations.
- Load-bearing retaining walls, supports and other similar structures have traditionally been constructed of concrete poured at the site, a process which is time-consuming and labor-intensive. To save time and expense, precast building blocks have been developed for use in erecting retaining walls, supports and the like, some of which are suggested for use in constructing a bridge abutment.
- In US patent 4982544 to Smith, there is described a precast concrete module for use in constructing retaining walls capable of sustaining large vertical loads. In constructing a load-bearing wall using these modules stacked in rows, a stabilizing means is required, such as metal sheets inserted through slots in the rear connecting walls. The module described by Smith has a front wall, a partition wall, at least two front connecting walls and a rear connecting wall. The region between the front walls and the partition walls of the assembled modules is filled with poured concrete to create a load-bearing retaining wall. The step of pouring concrete is again time-consuming.
- A particularly advantageous type of building block is that in which individual elements interlock, forming a secure, stable structure requiring little or no cement or other adhesive material, thus reducing the cost of material and time required for construction.
- Several types of interlocking blocks have been described, including the following patents:
- 5181362 to Benitez;
- 5588271 to Rabassa;
- 4651485 to Pitchford;
- 5379565 to Vienne;
- 4514949 to Crespo;
- 4573301 to Wilkinson;
- 4627209 to Schwartz;
- 4075808 to Pearlman;
- 4031678 to Shuring; and
- 3936987 to Calvin.
-
- All of these describe a design in which blocks can be connected at their upper and lower surfaces and along two of their four vertical sides. This enables building of a construction having only one row of bricks in a horizontal direction, and not a continuous structure extending in all directions, thus limiting the load distribution, and ultimately the load-bearing capacity of the structure.
- In addition, many of these blocks comprise a solid unit and do not have internal cavities to facilitate the placement of insulation, pipes or conduits. In such solid units, the use of filling material, which may be used to add weight to the modules, is prevented. This may be a particular disadvantage in the case of a retaining wall in which such filling could add weight to the modules to counteract the forces exerted by fill to the rear of the wall.
- An interlocking block and a retaining wall system derived from such blocks is described by Risi (US 4815897). In this wall system, blocks are arranged in end-to-end relation and one upon the other in an overlapping manner, with projections on the upper surface of one layer fitting into recesses on the lower surface of the upper layer. This system does not have a very high level of stability and is not suited for bearing large vertical loads.
- Therefore, it would be advantageous to provide an interlocking system of hollow, load-bearing elements which can be used with or without filling material in mortarless construction of retaining walls, overhead passageways, artificial islands and the like.
- Accordingly, it is an object of the present invention to overcome the disadvantages of the prior art and provide interlocking building elements which can absorb large horizontal or vertical pressures, and thus eradicate or minimize the effects of active pressure.
- It is a further object of the present invention to provide interlocking building elements that can be connected along each face to form a stable, continuous, multi-directional structure, requiring no cement or other stabilizing material.
- It is a further object of the present invention to provide elements which are hollow and can be filled with any required material.
- In accordance with a preferred embodiment of the present invention, there is provided a system of modular interlocking building elements comprising a plurality of rigid, hollow polygonal elements, having vertical faces, a first portion of said polygonal elements provided as base elements arranged as a base layer, a second portion of said polygonal elements provided as interlocking elements arranged as an intermediate layer above said base layer, a third portion of said polygonal elements provided as interlocking elements arranged as an upper layer above said intermediate layer, said interlocking elements in said intermediate layer being formed with a vertical slit in all of said vertical faces, said interlocking elements in said upper layer being formed with vertical slits in at least two of said vertical faces, such that said at least two vertical slits of each of said intermediate layer elements engage said base elements, and said at least two vertical slits of each of said upper layer elements engage said intermediate layer elements, said base, upper and intermediate layers providing a mortarless, multidirectional, load-bearing construction.
- According to a preferred embodiment, there is provided a series of interlocking, quadrilateral, hollow, elements, each provided with vertical slits for engaging the upper half of the face of one or two similar modular elements. The interlocking elements form a continuous structure, which will counteract the active pressure exerted by any filling material. Thus, the load exerted on the structure develops forces which are constrained within the element and these forces are not spread horizontally to the surrounding foundation.
- A feature of the present invention is to provide modular elements for use in construction of structures in which active pressure is a factor, such as retaining walls, bridge abutments, ramps, dams, artificial islands, etc.
- An advantage of the present invention is the minimization of active pressure, resulting in economization on filling material, ground area, area of foundations, etc.
- A further advantage of the present invention is that the interlocking structure of the elements enables construction in all directions, permitting even load distribution and adding to the load-bearing capacity of the entire construction. The vertical and horizontal interlocking enables the construction of an even surface without the use of adhesive material between the elements.
- The modular elements of the present invention may also be used as building construction elements without filling material, for example in the construction of overhead passageways.
- Additional features and advantages of the invention will become apparent from the following drawings and description.
- For a better understanding of the invention with regard to the embodiments thereof, reference is made to the accompanying drawings, in which like numerals designate corresponding sections or elements throughout, and in which:
- Fig. 1 is a general perspective view of a construction using the modular elements in three layers;
- Fig. 2 is a top view of the modular elements forming a base layer;

- Fig. 7 is a perspective view of the modular elements of the uppermost layer.

- Fig. 1 shows a perspective view of a
construction 10 using a series ofmodular elements 12. Theelements 12 are hollow, quadrilateral framing elements, provided as blocks, typically known as construction blocks, having only vertical faces, with no upper or lower horizontal face. In a preferred embodiment of the present invention, theelements 12 are square, but other shapes, such as rectangles or polygonal shapes, by way of example, may also be used. Theelements 12 may be constructed, by way of example, from concrete, iron, or any other material appropriate to the present purpose. The blocks may be of any size, for example with faces having length between 0.2 meters up to several meters. Variations ofelements 12 are denoted aselements - Fig. 1 shows an
incomplete construction 10 comprising a system of variousquadrilateral elements 12.Vertical slits 14 are formed on the vertical faces ofelements 12, extending upwards from the mid-point of the lower edge of the vertical face. The width ofslits 14 is equivalent to the width of the walls ofelement 12. The number ofvertical slits 14 formed on the vertical faces of eachelement 12 may differ, as described further below.Vertical slits 14 are designed to enable interlocking arrangement of layers of elements. - The framing
elements 16 which form the base layer ofconstruction 10 have foursmooth faces 20 with no vertical slits. In building ofconstruction 10, theelements 16 ofbase layer 30 are first arranged in the required formation.Elements 12 ofsecond layer 32 are then positioned withslits 14 over the horizontal mid-point of the wall of anelement 12 of thebase layer 30, so that the wall of thelower element 16 becomes engaged withinvertical slit 14 of theupper layer element 12. Since the width ofslit 14 ofelement 12 is equivalent to the thickness of the wall oflower element 16,element 16 is firmly and tightly engaged withinslit 14. -
Elements 28, having fourslits 14 are used for placement over arrangements of fourbase elements 16, as further described below with reference to Fig. 5. - The
elements smooth faces 20 having noslit 14. In this fashion, interlocking arrangement ofelements faces 20 placed in an outward-facing position to form a smooth, continuous outer surface. -
Element 22 is intended for placement so as to be surrounded on three sides byother elements face 20 forming an outer surface ofconstruction 10.Comer element 24 is designed to be positioned withadjacent elements - Subsequent layers are similarly constructed by appropriate use of the
various elements - Vertical slit 14 is of length equal to half the height of the vertical face in which it is formed, so that when three layers are interlockingly arranged one upon the other, the lower edges of the wall of the uppermost layer rests directly upon the uppermost edge of the lowest layer, thereby leaving no gap.
- As will be further described below, the modular elements are hollow, enabling the addition of filling material as required.
- Referring now to Fig. 2, a top view of the
base layer 30 of theconstruction 10 is shown. A series of hollow,quadrilateral elements 16, having no vertical slits, are placed side by side in the required arrangement, which in this example forms a rectangular arrangement. - Fig. 3 shows a perspective view of the
elements 16 ofbase layer 30, arranged so as to form a construction having irregular shape. - Fig. 4 shows
elements 28, having aslit 14 on each of four vertical faces.Element 28 is designed to interlock with fourelements 12, where the fourelements 12 are arranged so as to form a square, which will hold the fourelements 12 in a stable arrangement, requiring no mortar or other stabilizing material.Element 28, which is used inintermediate layer 32, does not extend to the outer perimeter ofconstruction 10.Element 28 is also used in the interior ofupper layer 34, in whichcase elements 28 will be surrounded byelements - Fig. 5 shows a
construction 10, in which theelements 28 of theupper layer 32 are arranged upon thebase layer 30.Elements 28 have aslit 14 in each of their four vertical faces. Eachelement 28 is placed over a group of fourelements 16 arranged so as to form a square, so that the central point of the square formed by the fourelements 16 coincides with the central point ofelement 28. In this way, each slit 14 holds together a side of each of twoadjacent elements 16 and fourelements 16 ofbase layer 30 are held within each second-layer element 28. - Referring now to Figs. 6a-c and Fig. 7, the individual modular elements are further illustrated.
- Fig. 6a shows a
modular element 22 having three slits, whereslit 14a is designed to engage the walls of two adjacent lower layer elements and is therefore double the width ofslits 14 which engage only one lower layer element wall. The shape ofelement 22 may be square or rectangular. - Fig. 6b shows
modular comer element 24 having twoslits 14, each of which engages one wall of a lower layer element. - Fig. 6c shows
modular elements 28 having fourslits 14a, each of which engage the adjacent walls of each of two lower level elements. - Fig. 7 shows the
modular elements 40 of the uppermost layer ofconstruction 10, in which an upperhorizontal surface 42 is provided, forming a closed upper surface. - The foregoing examples of
constructions 10 illustrate the flexibility of the interlocking construction system of the present invention, whereby continuation of construction can proceed along the direction of any or all of the four faces of anelement 12, as well as in an upward direction. The variations in the number of slits enable the various constructions to be formed having a smooth, continuous, outer surface, if so required. The hollow, framing structure of the elements enables theconstruction 10 to be filled after assembly with filling material, and to absorb or minimize the active pressure generated thereby. Filling material may be used, for example in the case of a retaining wall, to add weight to the modules to counteract forces exerted on the rear of the wall. - Alternatively, constructions without filling may be built, without filling, such as in the construction of overhead passageways. The design of the modules allows even weight distribution over the entire structure, thus creating a high load-bearing capacity.
- Furthermore, the interlocking arrangement of elements results in a stable construction, without need for mortar or other stabilizing material, increasing the speed and efficiency with which the construction can be erected, and also reducing the overall cost of materials.
- Many uses are envisaged for the modular construction elements of the present invention, such as retaining walls, ramps, artificial islands, overhead passageways etc. The system may also be used as bridge abutments. If the construction is to be built within a system of water, such as in a river, openings may be provided in the base layer of elements to enable passage of water.
- Having described the invention with regard to certain specific embodiments thereof, it is to be understood that the description is not meant as a limitation, since further modifications will now suggest themselves to those skilled in the art, and it is intended to cover such modifications as fall within the scope of the appended claims.
