Definitions

  • the present invention relates to the field of the drying of wet walls or floors.
  • It relates more particularly to an atmospheric siphon intended for the drying of walls, according to the Knapen process, and of the type comprising a cylindrical porous terracotta body in which is formed a longitudinal main channel opening onto the end faces of said porous body.
  • this humidity can be captured by natural evaporation, by practicing spaced and oblique piercings in the bases of the walls and by placing therein excessively porous atmospheric siphons, having a large absorption capacity, sealed in the piercings by a lean mortar, the main channel of which ends at an end face on one face of the wall, preferably the external face.
  • the holes are made in the basements of the wall in a direction directed towards the inside of the wall and slightly inclined upwards.
  • the siphons are long enough to fill the hole or are placed end to end in the hole.
  • the atmospheric siphon works on the principle of the exchange of two gases of different density. Each siphon attracts moisture from the wall within a certain radius and this permeates the porous wall of the siphon.
  • the dry air from the outside enters the main channel of the siphon through the end face of the siphon located on the chosen side of the wall, either external or internal, takes up moisture in the main channel, cools and, becoming denser, settles in the lower part of the main canal. Due to the inclination of the channel, the moisture-laden air flows by gravity outwards through the end face of the siphon, making room for a new quantity of dry air.
  • the disposition oblique siphons thus allows a natural circulation of air in the main channel.
  • Figures 1 and 2 of CH-A-344 547 show a device as defined in the preamble of claim 1.
  • a solid separating partition is arranged longitudinally inside the porous cylindrical body so as to separate the internal volume of the porous body in two spaces: a secondary duct situated above the separating partition and a main channel situated under the said partition.
  • This partition extends practically to the bottom of the porous body which, as can be seen in FIG. 1 of this document, is of concave hemispherical shape.
  • the disadvantage of this two-branch siphon is that it is difficult to mount the partition inside the bore of the porous cylindrical body so that it remains attached to the upper arch of this bore.
  • the invention intends to remedy this drawback and proposes to do this the arrangements defined in the characterizing part of claim 1.
  • the porous body and the attached wall are in intimate contact with the mortar intended to retain them in the inclined housing previously drilled in the wall.
  • the porous body used can obviously be opened at its two ends, its internal end then being plugged with the mortar, without risk of blocking the communication opening provided in the upper wall of said porous body.
  • the siphon is placed in the wall so that the second opening is inside the wall, the first opening leading to the external face of the wall which is fitted with an air grille.
  • the outside air can enter the main channel as in the prior art, but it can also replace the humid air, which flows from the main channel to the outside, by penetrating directly into the bottom. of the main channel through this secondary duct. As the outside air becomes charged with humidity in the main channel, it descends by gravity.
  • This atmospheric double branch siphon also allows drying of damp floors or floors. It suffices to provide a siphon of this type in the floor, the main channel and the secondary duct opening appropriately into the open air. Air can circulate naturally by gravity or be activated by suction or discharge.
  • the porous body advantageously has on its external cylindrical face a plurality of grooves.
  • two adjacent grooves are separated by a protuberance formed on the porous body and having longitudinal ridges.
  • the wall added in the form of an inverted gutter is fixed on two adjacent protuberances and covers a longidutinal groove.
  • the attached wall is made of terracotta and is fixed by gluing to the porous body.
  • the porous body has a cross section of octagonal shape and has a flat underside and seven grooves.
  • the latter additionally comprises means making it possible to adjust the section of the second orifice.
  • the atmospheric siphon 1 shown in the drawing comprises a cylindrical porous body 2 made of terracotta in which is formed a main longitudinal channel 3 which opens onto the end faces 4 and 5 of the porous body 2.
  • the porous body 2 has a section of substantially octagonal shape and has a substantially flat lower face 6 and seven concave faces each formed by a longitudinal groove 7.
  • a longitudinal protuberance 8 comprising grooves 9 is formed on the external cylindrical face of the porous body 2 between two neighboring grooves 7a and 7b.
  • the main channel 3 has a substantially circular section and has longitudinal grooves 10 in its upper part.
  • An attached wall 11 is disposed above the upper groove 7c.
  • This added wall 11 has the shape of an inverted gutter and its two longitudinal edges 12a and 12b are spaced apart by a distance equal to the width of the groove 7c and bonded to the protrusions 8a and 8b adjacent to the groove 7c.
  • the attached wall 11 is also made of terracotta and it delimits with the groove 7c a secondary conduit 13 which opens into the planes of the end faces 3 and 4 of the porous body 2.
  • a communication opening 14 passing right through the upper wall of the porous body 2 is formed in this upper wall in the vicinity of the end face 5 of the porous body 2.
  • This communication opening 13 opens into the upper part of the main channel 3 and connects the main channel 3 and secondary duct 13.
  • the atmospheric siphon 1 is intended to be placed in an oblique hole made in the base of a wall 15, the end face 4 of the siphon 1 being in the vicinity of the external wall 16 of the wall 15 and being protected by a grid 17
  • the axis of the siphon 2 is directed towards the inside of the wall 15 and slightly upwards.
  • the main channel 3 and the secondary duct 13 are blocked on the side of the end face 5 either by the material constituting the wall 15 or by the lean mortar used to seal the siphon 1 in the wall 15.
  • the atmospheric siphon 1 further comprises means 17a making it possible to adjust the section of the communication opening 14 so as to modify at will the air flow circulating in the siphon 1.
  • These means 17a preferably consist of a disc 18 arranged transversely in the bottom of the main channel 3 and fixed to a removable rod 19 arranged in the axis of the main channel 13 and whose free end 20 is located in the vicinity of the grid 17.
  • the disc 18 is very thick and it comprises, in its upper part and on the side of the grid 17, a notch located in the vicinity of the opening 14. It is made of terracotta and is porous. Its large volume promotes the absorption of moisture.
  • a groove, not shown in the drawing, putting the bottom of the main channel 3 in communication with its front part, is provided in the lower part of the disc 18.
  • the axial displacement of the rod 19 causes the axial displacement of the disc 18 which acts as a shutter piston which makes it possible either to completely open the opening 14, or to close it partially, or to eliminate the communication between the main channel 3 and the secondary duct 13, the siphon 1 then functioning as an atmospheric single-branch siphon of the prior art.
  • the siphon 1 is made of terracotta. It is porous and very absorbent.
  • the external shape of the porous body 2 and the presence of the grooves 7 and the external 9 and internal grooves 10 improve the absorption capacities of the siphon 1.
  • the air is found in the main channel 3 is charged with moisture, becomes heavier and tends to descend by gravity into the lower part of the main channel 3, and to escape through the end face 4.
  • the section of the secondary conduit 13 is less than the section of the main channel 3, therefore the speed of the air in the secondary duct 13 is greater than the speed of the air in the main duct 3, and the fresh air sucked in the secondary duct 13 accelerates the renewal of in the main channel 3.
  • the section of the communication opening 14 is substantially equal to the section of the secondary duct 13 so as to avoid excessive pressure drops.
  • FIG. 4 shows an example of the use of an atmospheric siphon 1 for the drying of a moist and horizontal soil or floor 30.
  • the air circulation in the siphon 1 is carried out by ventilation sucking the humid air from the main channel 3 or blowing outside air into the secondary duct 13 .
  • the secondary conduit 13 is arranged above the main channel 3. It goes without saying that the secondary conduit 13 can be produced by a tube of small section, having a length less than the length of the siphon, disposed in the main channel 3 and opening through a first orifice 21 in the end face 4 and through a second orifice in the area of the main channel 3 located near the end face 5.
