Definitions

  • the invention relates to building blocks of a building wall. Specifically, these are blocks prefabricated.
  • the invention also relates to constructions obtained by stacking such blocks, as well that a construction process to build a wall of building using these blocks.
  • An object of the invention is to provide blocks prefabricated and having a core of insulating material, which once stacked to form a wall, ensure better sealing, by simple, reliable and inexpensive means.
  • the mesh consisting of building material cast in place, e.g. concrete filling the grooves of the blocks, forms a joint blocking the penetration of water to the surface internal wall.
  • the subject of the invention is also a building comprising blocks as mentioned above, juxtaposed in several horizontal rows stacked together on the others by forming at least one wall, the gorges upper and lower blocks respectively belonging to two superimposed rows delimiting a conduit horizontal extending over the entire length of said rows and which is filled with building material cast in place, and the vertical grooves of the adjacent blocks of a same horizontal row delimiting a vertical passage which is filled with said building material cast in place, the building material poured into horizontal conduits and in the vertical passages thus constituting a mesh which creates a tight barrier between the blocks.
  • the invention has for object a method of constructing a building such as defined above, in which one successively realizes each horizontal row of blocks and when performing each of said horizontal rows, the solid vertical blades between the webs and the planelles exterior of the juxtaposed blocks constituting said row horizontal, thus covering spaces between the outer planelles of adjacent blocks.
  • the building block 1 is formed of a core 2 and two planelles vertical 3, 4.
  • Block 1 can for example have a height and thickness (perpendicular to the planelles 3 and 4) of approximately 250 mm and a length L of approximately 500 mm.
  • the core 2 consists of a molded shim, substantially parallelepiped, of a thermal insulating material such as expanded polystyrene having for example a density of approximately 20 kg / m 3 or greater.
  • the core 2 has a horizontal upper face 5, a horizontal lower face 6, a vertical external face 7, a vertical internal face 8 and two vertical lateral faces 9.
  • the external face 7 is covered with the external plane 3, while the inner face 8 is covered with the inner plane 4.
  • the outer plane 3 is intended to form the exterior surface of a building wall formed from blocks 1, and can be made of concrete facing textures and various colors. Its thickness is for example around 30 at 40 mm.
  • the inner plane 4, also made in facing concrete or similar, is intended to form the interior wall surface. Its thickness is for example about 20 to 30 mm.
  • the core 2 and the planelles 3 and 4 are joined by grooves and engravings 18 in dovetails.
  • the dovetails are formed by the core 2.
  • the core 2 is set back, for example about 1 cm, relative to the planelles 3 and 4.
  • the core 2 projects about 1 cm from planelles 3 and 4.
  • one of the side faces 9 is set back from the edges side of planelles 3, 4, while the other of these faces side protrudes from the side edges of the planelles 3, 4, opposite the previous edges. So when their implementation, the positioning of blocks 1 is ensured by interlocking of the souls 2 of the blocks between the planelles of neighboring blocks.
  • the core 2 is crossed by two vertical conduits 10, the central axes of which are situated substantially at a quarter and three quarters of the length L of the core, (in other words, the central axis of each conduit 10 is at a distance L / 4 from the neighboring lateral face 9).
  • These vertical conduits 10 have a substantially square cross section, for example substantially greater than or equal to 100 cm 2 (advantageously about 10 cm on a side), and they are intended to be filled with a building material cast in place, such as concrete. They make it possible to produce a succession of posts distributed approximately every 25 cm and constituting the vertical frame of the load-bearing framework of the wall of the building produced by means of blocks 1.
  • a wall produced with the blocks according to the invention is therefore self-supporting and is suitable for construction type R + 1 (1 floor + 1 roof).
  • the vertical conduits 10 can be offset, towards the internal face 8, relative to the median plane of the core parallel to the planes 3, 4, in order to improve the thermal performance of the wall made up of blocks 1.
  • the core 2 further comprises, respectively on its upper face 5 and its lower face 6, a groove horizontal upper 11 and a lower groove horizontal 12.
  • the upper 11 and lower 12 grooves extend longitudinally parallel to the planelles 3 and 4 and perpendicular to the vertical conduits 10, on the entire length of the core 2.
  • the grooves 11, 12 are arranged in the same vertical plane as the conduits 10.
  • the upper grooves 11 and lower 12 have a cross section substantially square, for example 4 cm side.
  • the upper 11 and lower 12 grooves are continue, with the same cross section, over the entire height of the lateral faces 9, to form grooves vertical 21.
  • the core 2 also includes a channel vertical 14 for the passage of cables or conduits.
  • the channel 14 crosses the core 2 right through, between the grooves 11, 12 and the inner face 8 of the core, parallel to the vertical conduits 10 and substantially equidistant from these in the example shown.
  • blocks 1 of a row can be shifted in their direction longitudinal of a distance L / 2 from the blocks of the lower row and upper row. In that case, taking into account the positioning of the vertical conduits 10 of each block, these vertical conduits remain despite everything arranged in vertical mutual correspondence over the entire wall height.
  • the upper 11 and lower 12 horizontal grooves of the blocks 1 of two superimposed rows are then in mutual correspondence and form a horizontal conduit 13 which spans the entire length of the wall.
  • the vertical grooves 21 of the adjacent blocks in the same row horizontal 20a, 20b, 20c of the wall delimit between them a interblock vertical duct 19, vertical ducts 19 being offset by a distance L / 2 between blocks 1 of a row horizontal and blocks 1 of the horizontal rows above and from below.
  • the concrete thus poured has a subsidence at the cone of Abrams such that a slab with a concrete diameter of 50 cm when the measurement of this subsidence (this measurement consists of fill with concrete a frustoconical mold, the height of which is 30 cm, the largest diameter is 20 cm and the most small diameter is 10 cm, to tip it tip up and measure the slump in the concrete after removing the mold).
  • the concrete comprises aggregates whose size is less than 10 mm, to avoid any obstruction of the vertical conduits 10, interblock 19 and horizontal 13 by these aggregates.
  • the bonding agent is a CPJ concrete (Portland cement compound) dosed for example at 350 kg / m 3 .
  • the concrete fills progressively the vertical interlock 10 conduits 19 and horizontal 13 to form after setting the concrete a rigid frame for the wall thus constructed.
  • the core 2 may optionally include, on its face upper 5, a horizontal drainage groove 15.
  • This horizontal drainage groove 15 extends over the entire length of the core 2, parallel to the upper groove 11.
  • This horizontal drainage groove 15 is located by example about 1 to 2 cm from the outer face of the core 2. In particular, it may have a width of around 2 cm.
  • the bottom of the horizontal drainage groove 15 can advantageously be on a downward slope towards the outer face 7 of the core 2.
  • the depth of the groove of horizontal drainage 15 is for example at the most deep, about 1 cm, and at the shallowest point about 0.5 cm.
  • This drainage groove 15 allows collect water that could possibly infiltrate in spaces 3a (left free or filled with a seal, especially in cement mortar between the horizontal edges outer planes 3 of blocks 1 arranged one on the other in a wall made using such blocks (see figure 2).
  • the drainage groove 15 is continues, on each of the side faces 9, with a groove vertical drainage 16.
  • This drainage groove vertical 16 extends longitudinally parallel to the planelle 3. It can have a cross section similar to that of the horizontal drainage groove 15.
  • the vertical drainage grooves 16 allow the flow of water collected in the grooves of horizontal drainage 15 and collecting water which could have possibly infiltrated the spaces vertical 3a (free or filled with a mortar joint or similar) between the outer planes 3, in the direction of arrow E shown in FIG. 3.
  • each block 1 can include in in addition to a groove 15a on the underside of its core 2, arranged in correspondence with the upper groove 15 above.
  • This additional groove 15a limits still the possibilities of water infiltration in the wall 2a.
  • the horizontal drainage grooves 15 and vertical 16 form, in the wall made up of blocks 1, a drainage network for water infiltrated into spaces 3a located between the outer planelles 3.
  • This network communicates with a drain located in the foundations of the wall, or with outlets 16a pierced in the lower part of the vertical grooves 16 of the lower block row 20a of the wall, these outlets 16a opening into the planelles 3.
  • This blade 17 is inserted between the cores 2 and the outer planes 3, in the direction of arrow 17a. Substantially half of the main surface of the blade 17 is inserted in block 1, while the other half of this surface is inserted in block 1 juxtaposed. So, the space 3a left between these blocks is covered, on the side of the face of the outer plates 3 which is in contact with the outer face 7 of the core 2.
  • This blade 17 is preferably made of a material rigid resistant to corrosion. It can be by example of an aluminum-based material or a material plastic.
  • blocks 1 could if necessary have a single central vertical duct 10 and grooves vertical 21 each corresponding to half the vertical duct section 10: in this case, the ducts vertical formed by the grooves 21 of two adjacent blocks 1 would correspond with conduits 10 in the wall 20, the concrete posts being then delimited alternately by the conduits 10 and by the grooves 21, from one horizontal row to another.
