Definitions

  • the invention relates to a building block with integrated insulation and a method for constructing the walls of buildings, public or private structures or the like from such building blocks.
  • the object of the invention is therefore to overcome these drawbacks by proposing a building block having an integrated insulation capable of meeting the most stringent certification standards in terms of thermal and acoustic insulation as well as possibly to anti-corrosion standards. seismic. It also relates to a method of building a wall from such building blocks that allows a quick and easy assembly by reducing the exposure time and eliminating the pollution usually generated on construction sites.
  • a rectangular parallelepiped-shaped building block comprising a first formwork part made of a concrete or cement material and a second formwork part made of a concrete or cement material rigidly connected to each other by two non-adjacent connecting parts of a thermally insulating material and leaving between them a central space intended to receive a central connecting portion of a thermally insulating material ensuring a continuity of the thermal insulation with said two connecting parts and a vertical keying between superimposed blocks, said shuttering parts being devoid of internal wall facing said central connecting part, so as to allow their mechanical connection via said central connecting part during the casting of a concrete web in each of said parts of formwork.
  • said first and second formwork portions each comprise on their inner wall recesses for cooperating with complementary ribs made opposite one another in each of said connecting portions so as to form a unitary assembly and each comprise on one lateral end face a recess. and on an opposite lateral end face a complementary rib, the recess of a given building block cooperating with the complementary rib of an adjacent building block and vice versa.
  • Said recesses and said complementary ribs are of the tenon and mortise type and advantageously have a dovetail profile.
  • said first and second formwork portions each comprise a discontinuous internal longitudinal wall and formed in two separate panels each having a length greater than that of the corresponding connecting portion and an integral longitudinal longitudinal wall forming the longitudinal end face. of the building block.
  • each of said two inner panels has a length substantially equal to one third of the total length of the building block.
  • each of said two inner panels is connected to the outer longitudinal wall by two transverse walls delimiting between them and this outer longitudinal wall two independent vertical chimneys, the inner transverse walls not forming parts of the two lateral end faces. of the building block, delimiting between them a lateral space on either side of said central space.
  • each of said transverse walls has at its apex a notch to allow said chimneys of each formwork part to communicate with each other via said lateral space and with chimneys of the adjacent right and left side building blocks.
  • said first formwork portion serves as an inner bearing wall and has a width greater than said second formwork portion acting as exterior facing wall.
  • Said connecting portions may be constituted by an expanded polymer, such as a polystyrene or polyurethane foam.
  • said building block is constituted by the only assembly of said second formwork portion with said connecting portions.
  • the present invention also relates to a method of constructing the rectangular parallelepiped-shaped building block comprising a first formwork part made of a concrete or cement material and a second formwork part made of a concrete or cement material rigidly connected to one another. to the other by two non-adjacent connecting parts of a thermally insulating material and leaving a central space between them, characterized in that, after having mounted a first row of blocks, to ensure a continuity of the thermal insulation with said two connecting parts and a vertical keying with the blocks of at least the second row, a central connecting portion is embedded in said central space of each block before mounting said second row of blocks and so on until reaching the height of the wall to be built, and it is proceeded in each of said shuttering parts to the casting of a bead the mechanical connection of which with said central connecting portion is ensured by the fact that said shuttering parts have no inner wall facing said central connecting portion.
  • FIGS. 1 and 2 show an embodiment of an insulated building block according to the invention.
  • This block 10 has a rectangular parallelepipedal shape with a first shuttering portion 12 made in one piece by molding a masonry material such as for example concrete, cement or terra cotta and a second formwork portion 14 made one piece by molding a masonry material such as for example concrete, cement or terracotta, these two shuttering parts being rigidly connected to each other by two non-adjacent connecting parts 16A , 16B each made of a piece by cutting, molding or any other suitable technique, a thermally insulating material and leaving between them a central space 18 for receiving a central connecting portion (see reference 40 on the figure 3 ) also produced in one piece by cutting or molding a thermally insulating material ensuring a continuity of the thermal insulation with the two connecting parts arranged on either side and a vertical keying with the adjacent building blocks upper and lower respectively.
  • Each inner or outer form portion is formed of two parallel longitudinal walls interconnected by four transverse walls.
  • the inner longitudinal wall of each formwork portion is discontinuous and formed into two separate panels 12A, 12B; 14A, 14B each having a length greater than that of the corresponding connecting portion and substantially equal to one third of the total length of the building block while the outer longitudinal wall forming the longitudinal end face of the building block is formed of a single holding 12C; 14C.
  • Each of the two inner panels of each formwork part is connected to the outer longitudinal wall by two walls transverse 12D, 12E, 12F, 12G; 14D, 14E, 14F, 14G delimiting between them and this external longitudinal wall two independent vertical chimneys 12H, 12I; 14H, 14I, the inner transverse walls 12E, 12F; 14E, 14F not forming parts of the two lateral end faces of the building block, delimiting between them a lateral space 20A, 20B on either side of the central space 18.
  • Each of these transverse walls has at its apex an indentation 22 which allows the two chimneys of each formwork part to communicate with each other via the lateral space and with the chimneys of adjacent building blocks right and left side.
  • the inner panels 12A, 12B; 14A, 14B of these two formwork parts each comprise, on their internal facing faces, recesses 24 to cooperate with complementary ribs 26 formed in correspondence in each of the connecting portions 16A, 16B.
  • these recesses and ribs are of the mortise and tenon type and advantageously comprise a dovetail section. But, of course, any other section allowing a locking between the parties facing is also possible, for example a T-section.
  • each of the inner panels also comprises an angled cutout 28, the four cutouts thus formed being intended to receive the four parts d angle of this central connecting part.
  • each of four transverse walls 12D, 12G; 14D, 14G forming a portion of the lateral end face of a given building block comprises a mortise 30 or is extended by a pin 32 to cooperate with respectively a tenon or mortise of the immediately adjacent block.
  • these mortises and tenons may comprise a dovetail section.
  • the figure 3 shows a high facade wall with building blocks according to the invention. It should first be noted that unlike traditional cement block constructions, building blocks are aligned and unmounted to anyone, which avoids the production of falls and waste. Then, unlike these traditional constructions, the laying of the blocks is carried out dry joint without cement, mortar or glue avoiding the production of dust. The horizontal anchoring of the blocks between them is carried out by the mortises 30 and the tenons 32 on the lateral faces of each block while the mechanical resistance between the blocks at the vertical level is obtained by the keying made by the central connecting part 40 which is introduced during the assembly of the wall on site and crosses several of these superimposed blocks, and in particular, as illustrated in FIG. figure 4 , at least the blocks of the upper and lower adjacent rows.
  • This alignment of the blocks causes a vertical alignment of the different chimneys of the formwork parts and a horizontal alignment of the notches of the transverse walls which will allow, by pouring concrete, the creation of two concrete webs 42, 44 in these two parts of formwork , which webs will be mechanically connected by the successive central connecting portions of the different blocks on the two opposite faces of which the concrete will adhere and further cling in the recesses 40A, 40B, so as to finally imprison these connecting parts central in the pouring of concrete.
  • a vertical and horizontal reinforcement can be introduced throughout the wall through chimneys and notches respectively due to their horizontal and vertical continuity.
  • electrical or hydraulic ducts can be passed inside the building blocks and drowned during the casting of concrete sails.
  • the first formwork portion will have a width greater than the second formwork portion and will then function as interior loadbearing wall while the second part of less large formwork will act as exterior facing wall.
  • the overall width of the building block can thus vary between 35 cm (15 cm of interior wall, 10 cm of insulation and 10 cm of external wall) and 50 cm (with 25 cm of insulation) depending on the width of each of these walls and the level of insulation sought.
  • the figure 5 shows a section of a wall comprising at the end of two standard building blocks 50, 52 as described above, two corner building blocks, one 54 described as “re-entering” the other 56 of " outgoing ".
  • These two blocks each have a structure slightly different from that of a standard block while keeping of course the essential feature, that is to say the fact that the two parts of formwork which then comprise longitudinal walls no longer flat but L-shaped have no inner wall facing the central connecting portion 54A, 56A, so as to allow their mechanical connection via the central connecting portion during the casting of concrete sails in the formwork parts.
  • both the continuity of the concrete pour all along the wall and the thermal continuity through the junction of the connecting parts are ensured.
  • vertical keys 60 inserted into the mortises 30 of a standard block 50 and the corresponding mortises 54B of the re-entrant angle block 54 allow horizontal anchoring of this corner block.
  • FIG. figure 6 The interest of the building block according to the invention for the mounting of a floor is illustrated in FIG. figure 6 . Indeed, it is possible by separating the inner form part of the rest of the building block as shown in the drawing to the left to make a wall / floor connection without thermal bridge.
  • the assembly is as follows: on a standard block 70 is disposed an outer formwork portion 72, the vertical keyway being formed by the central connecting portion 40.
  • the slab support or the floor insulation plate 74 is then placed on the internal formwork portion 76 of the standard block 70 slightly set back from the central connecting portion to leave a space for the attachment of the concrete to the recesses of this central connecting portion, during the casting of the concrete slab 78.
  • the external formwork of the floor is obtained directly with continuous insulation formed by the insulating parts 16A, 16B of the building block and the central connecting part 40 and the formation of a thermal bridge at the right of this floor is avoided.
