Definitions

  • the subject of the present invention is boxes and systems insulation and drainage of natural soil or added soil.
  • the technical sector of the invention is the field of work public and building.
  • One of the main applications of the invention is dubbing external vertical walls of a building, either internally for habitable parts that we want to insulate, both thermally and phonically, either externally for the parts buried in the ground and that we want to insulate, both against humidity and thermally.
  • the system according to the invention can be used for the production of supports for floor slabs the interior of a building and whose sound insulation is to be preserved and thermal, as well as protection against rising damp.
  • Another application is the recovery of seepage water in the ground of a ground covered for example by plantations which need to be watered.
  • the problem is therefore to be able to have elements of prefabricated construction, which are usable, as well for insulation, both thermal and sound, and also to achieve drainage systems, using the same basic technique, and of products and construction elements of the same type, using products available, either in the wild or on the market at a cost low, with efficiency guaranteed for long periods, with a quick and simple installation and implementation, with the less site equipment possible, and for an overall cost of supplies and installation as small as possible.
  • the invention has for object a closed box of rectangular parallelepiped shape, flattened on two main faces opposite, separated by four so-called lateral faces, the internal volume being filled with rigid fragments of pozzolan, which is a granular material with a honeycomb structure, density less than 1, and a good thermal insulation capacity;
  • the six walls of the outer casing of the box are rigid, weak thickness, and made of resistant material, at least one of which said to be main, is perforated by microholes, able to pass water, air or other fluids but not the pozzolan grains, which main faces are connected by at least one internal stiffener.
  • Said box consists of a receptacle formed by one of its main faces integral with the four side faces, and a cover forming the other so-called main face, said cover being fixed on said receptacle after filling of the granular material.
  • At least two of the side faces facing said boxes have, for one, at least one male protuberance convex towards the outside of the face which supports it, and for the other, at least one female bowl concave with respect to the face which supports it and which can cooperate with the male outgrowth of another box placed against the first.
  • the invention further relates to an insulating system and a draining system.
  • the walls of said boxes are, either all perforated, or only a part of them, as specified in the description and in the examples of the attached figures.
  • Such boxes according to the invention have dimensions, for their main faces on the order of 40 cm x 80 cm, or 50 cm x 50 cm either square, and for a height of their side walls of on the order of 12 to 20 cm; these walls can be made of HDPE and the filling material being pozzolan, the weight of a box is from 30 to 50 kg, either transportable by one person and therefore easy to place and stack on top of each other, without equipment special handling. This weight is indeed the maximum authorized by labor regulations in France; and the possibility of nesting boxes relative to each other, ensures their stability and alignment at least vertically, without requiring adjustment of the from the operator.
  • pozzolan as a granular material, in addition to its lower density allowing even more implementation easy boxes according to the invention, allows better resistance to temperature, because, on the one hand, pozzolan is a good insulator, leaves a always free passage between its grains and resists frost well: its qualities have been known and used since Roman times as an aggregate in insulating cements in certain constructions near places of production that are Auvergne in France and certain regions Italian.
  • Pozzolan is indeed a variety of rock of origin volcanic with alveolar structure, formed of slag remained in the state furniture, which is found in very large quantities in massifs volcanic: its mechanical characteristics are in particular its low density of 0.980, due among other things to its porosity, but also of good thermal and sound insulation capacity, a ability to withstand large and abrupt changes in temperature, grain roughness, richness in various components natural and a fairly good compactness and clean rigidity, avoiding its crushing, mechanical resistance to impact, wear and agents aggressive, all of whose characteristics are well known, and which can be referred to elsewhere.
  • Figure 1 is a perspective view of an open box next the invention.
  • Figure 2 is a sectional view along a plane I / I 'passing to the times by the axis of a protuberance and an internal stiffener of the box Figure 1.
  • Figure 3 is a perspective view of an exemplary embodiment of a system according to the invention for the internal insulation of walls of a building.
  • Figure 4 is a sectional view of a wall isolated by a system of boxes according to figure 3.
  • Figure 5 is a perspective view of an example of realization of the system according to the invention for the isolation of a foundation.
  • Figure 6 is an exemplary sectional view of a system according to the invention for the insulation of a floor.
  • Figure 7 is a sectional view of an embodiment of a system according to the invention for drainage and water recovery infiltrating into the ground after watering.
  • the box according to the invention is of rectangular parallelepiped shape, flattened on two main faces facing each other, separated by four so-called lateral faces, such as the six walls of its outer shell are rigid, thin, 0.3 to 1.5 mm, made of resistant plastic-like material HDPE (high density polyethylene), and at least one of the faces said main, is perforated by micro holes 12, preferably of on the order of 0.2 to 1 mm in diameter, and even 0.2 to 0.6 mm; which main faces are connected by at least one internal stiffener 3, of preferably hollow.
  • HDPE high density polyethylene
  • Said box consists of a receptacle 22 formed by one of its main faces integral with the four lateral faces, and a cover 2 forming the other so-called main face, said cover 2 being fixed on said receptacle after filling with rigid fragments of a granular material 11 with a honeycomb structure, which granular material is pozzolan: the opening of said boxes according to one of its large faces, allows easier filling than by one of the faces side, and the fixing of said cover 2 is carried out by pressing the periphery thereof on a lip also peripheral 7 bordering the opening of the receptacle 22, the assembly being bonded cold or hot, or stapled, riveted or whatever.
  • Said stiffeners 3 which are represented in FIG. 1 at number of 3, can be cylinders with a diameter of approximately 70 mm, as shown in Figure 4, but also and preferably trunks of cone, of identical median diameter and as shown in FIGS. 1 and 2: their largest base opens out, is open, and is integral with the main face forming the bottom 23 of the box 1; their most small base cooperates with a cup 4 interlocking integral with the other main face constituting the cover 2, ensuring centering when it closes, better support and better distribution of the loads that said box 1 could bear on its two opposite main faces 2, 22.
  • one of the main faces of the box in fact the bottom 23 of the receptacle 22, comprises at least three fixing lugs 8, each forming an appendage outwards, from three of the lateral faces and arranged in the plane of said main face 23 which supports them: in FIG. 1, it is example shown four legs along a long side of the rectangle of the bottom 23 and which will be positioned upwards, and two following the small ones sides; the other large side of the bottom 23 indeed does not need such legs which would even bother, because it comes to lean on the box already put in place.
  • each at least one orifice 9 with a diameter of approximately 50 mm per example which can be made in the form of a closed pre-hole during filling of the granular material in the box and cut out quickly on site to be connected to the neighboring orifice of a box placed side by side.
  • At least one internal stiffener 3 of one of said boxes 1 preferably placed towards the floor, is hollow and perforated, and connected to an air inlet 14 external opening in said wall 15, as shown in FIG. 4.
  • said boxes 1 can also include electrical resistors with temperature probes heaters arranged inside their volume 11, and connected to any electric source to diffuse heat in the room thus insulated.
  • Said boxes 1 are then placed in an excavation 16 dug around said building, to allow their installation, said excavation 16 can only be a narrow trench in which one slides said boxes.
  • said boxes 1 are used to isolate sound and against humidity a floor, consisting for example of a concrete slab 18 pouring on said caissons, themselves arranged on a basement 19 can be made of "all-purpose" material; said boxes 1 are in this case perforated on all their faces.
  • Figure 7 shows another particular example of use of a box according to the invention: a draining system constituted by the assembly of boxes arranged in a generally horizontal orientation plane against each other the others according to their lateral faces, and such that only their face main facing up is perforated, the entire plane constituted by the assembled boxes 1 being inclined; these are connected together by sleeves arranged in orifices 9 in opposite, and at least one recovery tank 20 is placed below of the lowest casing 24 and connected at least to the latter.
  • the recovery tank 20 can then also be connected to a filtration and pumping system to reuse water thus recovered by a pipe returning above the surface of the ground to ensure watering 21 thereof above the system of recovery constituted by said boxes 1; well, apart from the evaporation and absorption of water by the plants that we want water and loss of water in the surrounding land, much of it is still reused, reducing consumption overall required by said watering.
  • the boxes 1 can also be in this application, covered with a geotextile fiber, of the “Bidim” type (registered trademark), for their protection, said geotextile allowing water infiltration towards said boxes 1, and avoiding clogging of the micro-holes 12 of the main side facing up and should collect the water.
  • a geotextile fiber of the “Bidim” type (registered trademark)
