Definitions

• the present invention relates to a construction system and method for erecting walls using prefabricated building blocks and a method for implementing this construction system.
• binder Conventional construction methods use a binder to secure the blocks together.
• the binder is either mortar which is most commonly used, or glue for blocks with high dimensional accuracy, or concrete for blocks which in this case serve as lost formwork.
• the use of a binder poses serious problems, particularly in periods of frost and inclement weather, and the construction once completed is no longer removable afterwards.
• Document EP-A-0087872 discloses a building block having two side walls and two end walls, in which each end wall has at least one protruding tongue and a groove, the tongues and grooves being complementary so that the tongue and the groove of an end wall respectively overlap with a groove and a tongue of an end wall adjacent to an identical block placed in alignment with the first block.
• Document US-A-3461631 describes a building block comprising four intermediate cavities which open in the upper and lower faces of the block, the cavities having rectangular sections of decreasing surface from the upper face of the block to the underside so that when two blocks are superimposed so that two cavities in each block are in alignment with one another, these cavities form flared sheaths.
• the superimposed blocks are secured to each other by means of shims introduced into the cavities so as to be
• the object of the present invention is to overcome the drawbacks of known construction systems thanks to an improved construction system allowing easy and rapid assembly of prefabricated blocks without using a binder to secure the blocks together.
• a construction system for erecting a wall comprising a set of prefabricated blocks aligned in superimposed horizontal rows, each block having an upper face, a lower face and lateral faces, and each block being traversed by at least one cavity opening in the upper and lower faces mentioned above, the blocks being on the other hand arranged so that a cavity any block of a row is located in the axial alignment of a cavity of a block of an adjacent row, the system further comprising several anchoring parts for joining together the blocks of the rows superposed two in pairs, each anchor being positioned inside two cavities of two blocks belonging to two superimposed rows.
• each cavity has the shape of a straight parallelepiped with a square base
• the anchoring piece consists of a plate of generally rectangular shape, this plate having lower and upper beveled edges, the lower beveled edge being capable of cooperating with the upper beveled edge of a similar anchor on which the first anchor is placed and the beveled edge being able to cooperate with the lower beveled edge of a similar anchor which is superimposed on the anchor.
• the anchoring part has cutouts in its lower and upper edges, these cutouts allowing the fitting of two anchor pieces in a cross in the sheath formed by the alignment of two cavities of two blocks belonging to two superimposed rows, the lower cutout of one of the two anchor pieces fitting into the upper cutout of the other anchor piece.
• Figures 1 to 3 show three examples of standardized building blocks that can be used in the building system according to the invention.
• FIG. 4 represents a section of wall produced with the construction system according to the invention using the standardized blocks of FIGS. 1 to 3.
• FIG. 5 represents a superposition of blocks according to FIG. 2 and a first example of an anchoring part.
• Figure 6 is a sectional view of the assembly of Figure 5 in which the blocks are secured using the anchoring parts.
• Figure 7 shows the same blocks as in Figure 5 but with another example of an anchor.
• Figure 8 is a cutaway view of the assembly of Figure 7 but in which the blocks are secured using two exemplary anchor pieces placed crosswise.
• FIGS. 2 and 3 represent three exemplary blocks.
• the block 1 shown in Figure 1 has an internal cavity 2 having the shape of a right parallelepided of square section.
• the blocks shown in Figures 2 and 3 have respectively two and three internal cavities 2.
• the walls which separate the cavities advantageously have a thickness twice that of the walls which delimit the blocks externally.
• FIG. 4 To form a wall, several blocks are placed side by side and in superimposed rows as shown in FIG. 4.
• a first row 11 of blocks 1 being aligned and possibly fixed to the ground
• a second row of blocks 12 is disposed on the first row 11, taking care, as is conventional, that the joints between adjacent blocks are not aligned with the joints between the blocks of the lower row.
• the cavities 2 of the blocks of a row (for example row 12) are and must be aligned with the cavities 2 of the blocks of the " lower row (for example row 11) so as to form vertical ducts of constant cross-section
• Figure 4 shows the construction of corner walls using standardized blocks according to figures 1, 2 and 3.
• anchoring part 3 This part consists of a plate of rectangular genera ⁇ form, intended to be introduced into a sheath formed by two cavities 2 aligned with superimposed blocks.
• the anchoring part 3 is intended to be placed along a diagonal of the sheath and it is dimensioned so as to be able to position itself inside the sheath over a height which extends on either side of the separation plane between two superimposed blocks 1 (FIG. 6 ).
• the part 3 preferably has a beveled lower edge 4 and a beveled upper edge 5, these beveled edges being formed in such a way that the lower edge 4 of an anchoring part 3 can cooperate with the upper edge 5 of another anchor piece on which it is placed and in such a way that the upper edge 5 of said anchor piece can cooperate with the lower edge 4 of another anchor piece which is superimposed on it.
• Each anchoring piece 3 gets stuck against the walls of the sheath and between other similar anchoring pieces. In this way are rigidly secured two superimposed blocks and all of the anchoring pieces superimposed in the sheaths rigidly unites all of the blocks forming a wall.
• the position of the anchoring pieces 3 in the cavities 2 of the superimposed blocks is preferably made approximately at the same height.
• an anchoring piece of reduced height can be introduced into the cavities 2 of the blocks of the first row 11.
• each anchoring piece consists of a plate of rectangular general shape having cutouts 6 and 7 in the lower 4 and upper 5 edges (FIG. 7). The presence of these cutouts allows the cross laying of two anchoring pieces of this type in a sheath (fig 8).
• an appreciable advantage of this construction system according to the invention consists in that the construction thus produced can just as easily and quickly be dismantled.
