DESCRIPTION OF_THE_PREFERRED_EMBODIMEN__ Referring to figures 4, 5 and 6 there is æhown a block lO adapted to be superpo~qed on a corresponding s;milar block in order to form structural assemblies such as the building ll ;LIustrated in figure 1.
The b]ock 10 has a top face 12, a front wall 14, a back wall 16, a r.ight-hand waLl 18 and a left-hand wall 20. The walls 14, 16, 18 and 20 have a lower edge provided with a pending lip 22.
The pending lips 22 are provided by an extens;on of a portion of the thickness of the walls 14, 16, 18 and 20 a]ong the inner lateral surface 24 of the block 10.
Downwardly tapering wedge members 26 are secured to the inner sur~aces of the walls 14, 16, 18 and 20 above and adjacent the lips 22. In the smbodiment il.lustrated in figures 6 to 15, the wedge member 26 generally consists of adjacent independent wedge block formed integrally with the inner surface 24. A peripheral groove 28 is provided at the intersection of the top face 12 and the walls L4, 16, 18 and 20. The groove 28 is adapted to allow the penetration and the support of the pending lips 22 and the wedge member.s 26 of a corresponding superposed block 10', as shown in figures 10 and 10a. A marginal '` 2~;2~P~
edge 30 extends integralLy from the top surface 12 partly over the groove 28. The marginal edge 30 is adapted to retain the lips 22 and the wedge member 26 of the superposed block 10' in the groove 28 as ;llustrated in figure 10. In use, during assembly two block~s are positioned one on top of the other and a downward pressure is applied on the upper block until the wedge member 26 of the top block interlocks with the groove 28' of the bottom bLock. The marginal edge 30 tapers outwardly in order to allow the wedge member 26 to slide thereon during application of the downward pressure.
Various block presenting substantially the same features can be manufactured in a variety of shapes and sizes.
In the embodiment, more specifically illu~strated in the figures, each block 10 is adapted to support two superposed blocks 10' and 10". The blocks 10 and 10" are overlapping on each side, as illustrated in figure 1, of a center line 32 longitudinally del;miting the block 10 in two halves. When this particular embodiment is used, the block 10 is provided on its top surface 12 with a central groove 34 symetrically disposed with regards to tlle center line 32. The central groove 34 which is more specifically illustrated in figures 9, 10 and lOa, has two diametrically opposed contiguous central grooves 28' and 28"
similar in shape to the peripheral groove 28. As illustrated in figure 10, the groove 28' fittingly receives and grips the wedge member 26 and the lip 22' of the right wall 18' of a first superposed block lO . In figure lOa, a second superposed block 2~ 37 i9 mounted continously with the f;rst superposed block 10' on the block 10. The groove 28" grips the wedge member 26" and the lip 22" of the left wall 20" of the block 10".
In another embodisnent of the invention, a block such as the top left corner block 37 in the assembly illustrated in figure 3 does not have a central groove 34. The block 36 is equivalent to a block 10 separated in hal~ about its center line 32.
The two adjacent b].ocks 10' and 10" are connected together by a dovetail connection comprising a tenon 36" and a mortise 38". In the embodiment illustrated in figures 3 to 10, the block lQ has a tenon 36 extending integrally from the left wall 20 and a mortise 38 formed in the right wall 18 as well as two mortises 38 formed integrally with the back wall 16. The blocks 10 can be arranged in a variety of patterns such as the pattern illustrated in figure 3. For aesthetical reasons, the bottom right corner b]ock is exempted from having a mortise on its right-hand wall.
A set of base blocks 40 are provided to seal off the blocks 10 of the lowermost row 43 of a given construction as~semb].y. E;ach base b]ock 40 has a flat base plate 42, a connecting rim 44 extending integrally and upwardly from the flat base p].ate 42 and a peripheral pending ].ip 46 a].so extending upwardly from the flat base 42.
As i]lustrated in figure 12, the rim 44 defines a 2~42~
groo~e 48 adapted to receive and grip the pending lips 22 and the wedge member 26 of the block 10 of the 1.owermost row 43 (see figure l). A pair of apertures 50 extend through the flat ba.se plate 42. Fixing means such RS screw9 or bolts can be inserted in the apertures 50 to fix the base block 10 to a structural element such as a foundation 52.
A set o~ top cover blocks 54 are used to provide a f].at top surface exempt from any grooves such as groove 28. The top cover blocks 54 have top flat plate 56 and a peripheral wall 58 extending downwardly from the top flat plate 56. The top cover. b].ocks 54 are provided with a dove tail 36 and a mortise 38. The lip 22 and a wedge member 26 is provided for interlocking assembly with the groove 28 of the corresponding blocks 10.
When the blocks lO are used to build houses having an inclined roof 61 (figure l) such as the building illustrated in figure l and 2a, a set of inclined top cover blocks 60 are mounted on the block lO adjacent the roof 61. The inclined top cover blocks 60 are similar in construction to the top cover blocks 54 except that their top surface 62 is forwardly inclined and consequently, the back wall 16 ;s greater in length than the front wall 14. Aga;n, the blocks 60 are provided with a lip 22 and a wedge member 36 for interlocking assembly. The blocks 10, 40, 54 and 60 being ho].low, they are adapted to be filled with adequate thermally insu]ating material such as fiberg]ass wool or the like.
