Definitions

  • the present invention relates to a method of protecting floors above the crawl space and buildings on foundations of the crawl-space type from damp and microbial growth, where the crawl space is delimited by the floor above the crawl space of the building, bearing foundation walls with vents for outdoor air and the foundation ground.
  • the invention also relates to an arrangement for use in application of the method.
  • Building foundations of the crawl-space type that is to say foundations where there is a crawl space between the floor of the building and the foundation ground, which crawl space is delimited in the lateral direction by bearing foundation walls, have traditionally been ventilated with outdoor air via vents located in the foundation walls.
  • Foundations of this type have functioned well in the past, one of the reasons for which is the fact that chimneies extended through the floor above the crawl space and down into the crawl space, which thus contributed to warming and drying the foundation and the air therein.
  • a certain degree of heat leakage down into the crawl space from rooms above also took place as a consequence of poor insulation of the floor above the crawl space. This, combined with correctly effected ventilation, meant it was possible to avoid problems of damp and mildew.
  • SE-B-7511197-1 describes the use of a perforated air-distributing layer.
  • the upper and lower zones therefore communicate with one another via the layer.
  • a higher pressure is used in the upper zone, which also means that air can be pushed back up into the building.
  • Leaks often occur at pipe bushings and other connections, which make it virtually impossible to prevent the positive pressure in the foundation pushing possibly bad air from the foundation up into the building. If radon gas is present, this too will be pushed up into the building.
  • SE-C2-507461 also describes a foundation with a horizontal partition.
  • This partition is intended to cause the ventilation air, which has been taken in via outdoor air vents, to flow along the lower surface of the floor structure, then to be drawn down into the foundation and discharged to the outside of the building.
  • the ventilation air which has been taken in via outdoor air vents
  • With outdoor air vents of this type major problems also arise as a consequence of the positive or negative pressure the wind pressure brings about on the different sides of the building. With the construction disclosed, it is likely that there is a positive pressure in the foundation at least at times.
  • the fan must nevertheless be dimensioned to handle very large quantities of air on account of inevitable leaks of the foundation wall also.
  • SE-400 362 B shows a method and an arrangement according to the preambles of claims 1 and 8.
  • the basis of the present invention is constituted by the knowledge that, for successful ventilation of crawl-space foundations, it is necessary to limit the volume of the foundation where the ventilation is to be monitored and controlled. This results in smaller quantities of air having to be handled and sealing of only a limited space being necessary, which is relatively easy to achieve compared with sealing an entire crawl-space foundation.
  • the crawl space is divided into upper and lower climate zones, which are sealed in relation to one another by means of a tight climate screen.
  • the upper climate zone is flowed through by warm indoor air, which keeps this climate zone dry and well ventilated, which prevents moisture deposition and mildew attack on, for example, the floor above the crawl space.
  • No regulation of the environment in the lower climate zone is then required, this zone being ventilated in a conventional manner by means of outdoor air vents in the surrounding foundation walls.
  • the crawl space is divided into at least one upper and at least one lower climate zone, that the two climate zones are separated from one another by means of an essentially windtight and vapourtight climate screen which forms a tight partition between the climate zones, that the climate screen is arranged at such a height in the crawl space that the outdoor air vents in the foundation walls communicate with only the lower climate zone, that the upper climate zone is provided with at least one supply air opening and at least one exhaust air opening, that the supply air opening is connected to a room above in the building and the exhaust air opening is connected to as discharge duct, and that a fan is arranged in association with the discharge duct so as to maintain a lower pressure in the upper climate zone than the pressure in said room above, so that the upper climate zone is ventilated by indoor air from the building and the lower climate zone is ventilated by outdoor air.
  • the supply air opening can be provided with a connecting duct for supplying dried air from a drying apparatus.
  • climate screen is thermally insulated so as to avoid any appreciable cooling of the ventilation air passing through the upper climate zone.
  • reference number 1 designates a bearing foundation wall of a building foundation of the crawl-space type.
  • the crawl space 2 is also delimited by the foundation ground 3 and an insulated floor structure 4 above the crawl space with an inner floor 5.
  • Reference number 6 designates one of the insulated outer walls of the building, reference number 7 relating to the outer panelling of the building.
  • the building obtains its supply air via one or more supply air vents 8 in the outer walls or alternatively from a conventional ventilation system.
  • the crawl space 2 is ventilated via a number of outdoor air vents 9, suitably provided with netting, mounted in the foundation walls 1.
  • the crawl space 2 is divided into at least one upper climate zone 10 and at least one lower climate zone 11.
  • the climate zones are separated by an essentially windtight and vapourtight climate screen 12 which is mounted essentially parallel to and at a relatively small distance from the underside of the floor structure 4 above the crawl space.
  • the distance between the climate screen 12 and the floor structure 4 can be as small as 1-2 cm but is usually 5-6 cm. If it is desirable to build in other installations, such as for example waste pipes and the like, the distance can be 15-20 cm or greater.
  • the volume of the upper climate zone 10 is considerably smaller than the volume of the lower climate zone 11.
  • climate screen 12 protects the floor structure 4 from the conditions in the lower climate zone 11, no special measures have to be taken with regard to the lower climate zone. This can therefore be ventilated in a conventional manner by means of the outdoor air vents 9 mounted in the foundation walls 1. This means that the climate screen 12 is always to be mounted at a higher level than the vents 9.
  • the upper climate zone 10 is to be sealed as well as possible against outdoor air.
  • the foundation walls 1 can be sealed over the part which delimits the climate zone 10 in the lateral direction.
  • this can be carried out effectively in a simple manner, for example by insertion of a sealing body 13 extending on all sides along the foundation walls 1.
  • the climate screen 12 is constructed from a number of insulating panels 14 joined together, which are suitably made of a rigid cellular plastic material, such as FRIGOLIT ® .
  • the panels 14 are suspended on swingable suspension elements 15 which bear mounting rails 16, as will be described in greater detail below.
  • Reference number 17 designates an air-distributing means which will also be described in greater detail below.
  • the climate zone 10 has supply openings 18 which are connected to supply air devices 19 with filters 20 in a room above in the building.
  • Two such supply air openings 18 are suitably arranged on each of two of the opposite sides of the building, one or two exhaust openings 21, 22 being arranged essentially centrally in the building and each being connected to a discharge duct 23 and, respectively, 24. These can also be combined to form a common duct. If the building is long, an extra supply air opening 18 is arranged every 8-10 m of building length.
  • the exhaust openings can consist of extraction pipes known per se with openings distributed along the pipe.
  • reference number 25 designates a suction fan connected to the ducts 23 and 24, with an outlet duct 26 which is suitably guided up above the ridge of the building. Supply air can be taken from any desired room in the building.
  • the fan 25 is adapted so as to maintain a lower pressure in the upper climate zone 10 than in the room above. This means that warm indoor air will be supplied to the climate zone 10 via the supply openings 18 and will flow along the underside of the floor structure 4 above the crawl space to the exhaust opening 21. As a result of the climate screen 12 being insulated, the air passing through the climate zone 10 will not be cooled to any appreciable extent during the cold time of the year either, for which reason no moisture deposition will take place. Radiant heat from the floor structure also contributes to this.
  • an air-distributing means 17 is arranged between the climate screen 12 and the floor structure 4 above the crawl space, which distributes the airflow essentially uniformly or in another desired manner in the climate zone 10.
  • the arrangement described above can be used in order to improve existing foundations, as no measures are necessary in the building apart from the supply air device and the extraction fan. Sealing of the foundation walls is not critical as a small amount of outdoor air leaking in can be tolerated as a result of the small air volumes which have to be handled in this connection.
  • the invention can of course also be used in the production of new buildings.
  • the climate zone 10 can be divided into sections with separate supply and exhaust openings for individual climate control if so desired.
  • the lower climate zone 11 can of course also be divided by further bearing walls or the like without functioning being affected.
  • the climate screen 12 can be varied depending on requirements and can consist of, besides tight cellular plastic panels, mineral wool panels, for example, if appropriate with a tight lower or upper surface layer.
  • the screen can, depending on the outdoor climate, also be uninsulated and consist of a tensioned fabric.
  • the panels 14 can be suspended from the floor structure 4, as shown, or be supported from below, for example, if this should prove to be suitable.
  • the supply air openings 18 can also be connected to, besides an optional air device 19, an air-conditioning system and/or air-drying equipment if so desired. This can be advantageous in, for example, buildings which are unheated for a certain part of the year.
  • Fig. 2 shows a cellular plastic panel 14 in a plan view and from one end.
  • the panel is provided with a groove 27 extending on all sides.
  • Fig. 3 shows how the grooves 27 are used, when adjacent panels are joined together, for receiving one half of a suspension and sealing rail 28 extending along the entire length or width of a panel.
  • the other half of the rail is inserted into the groove in an adjacent panel 14.
  • the rails 28 are provided with centrally located, slot-shaped openings through which swingable suspension elements 15 can be guided down and locked in the desired position.
  • the rails 28 can be made with longitudinal flanges which, in the event of an attempt to pull a rail out of a groove, are erected to perform a barb-like function.
  • the swingable suspension elements 15 are used, as can be seen from Fig. 4 , for suspending the panels 14 below the floor structure 4 above the crawl space.
  • the suspension elements 15 are fastened to the floor above the crawl space, and the mounting and sealing rails 28 are secured on the suspension elements 15 in the desired position to form a climate zone 10 between the floor structure 4 and the panels 14 with the desired height.
  • the mounting rails 28 can be fastened at the desired height, the panels 14 can be mounted in the same plane irrespective of any inclination of the floor structure 4.
  • the use of mounting rails 28 which are inserted into grooves 27 in the side edges of the panels 14 also means that small angular variations between the panels can be taken up, see Fig.
  • Fig. 6 shows a mounting and sealing rail 28 on larger scale.
  • the strip is provided with a longitudinal groove 32 which is provided with predetermined break points 33, see the sectional view in Fig. 6A , in order to allow material portions 34 to be broken away to form slot-shaped openings in the rail 28.
  • the transverse edges of the openings obtained will in this connection be formed by resilient tongues 35.
  • Fig. 7 shows a swingable suspension element 15 seen from the front and from the side.
  • the suspension element 15 is adapted so as to be fastened to a joist floor by screws or the like, which are guided through a hole 36 in the upper part of the suspension element, which is then angled into a position essentially at right angles relative to the remainder of the suspension element about a hinge axis 37.
  • the width of the suspension element 15 is essentially the same as or slightly greater than the length of the slot-shaped openings in the rail 28, which are formed when the material portions 34 are broken away. At least one edge of the suspension element is toothed, which results in the resilient tongues 35 of the openings of the rail 28 holding the suspension element in position in the respective opening and providing resistance to the suspension element being displaced through the opening.
  • the suspension element On the front side, the suspension element has mutually separate projections 39.
  • Fig. 8 shows a thin wedge 40 with a width essentially corresponding to the width of the suspension element 15.
  • the wedge 40 is adapted so as to be inserted through an opening in the rail 28 together with the suspension element and on the plane side of the latter, when it has been decided at which height the rail 28 is to be fixed relative to the suspension element 15.
  • the wedge 40 will then press the suspension element against one longitudinal edge of the slot in the rail, which edge then engages between two of the projections 39 in order to retain the rail 28 securely in the position taken up on the suspension element 15.
  • the lower portion 42 of the wedge 40 is hinged about an axis 41, which facilitates gripping the wedge after mounting.
  • Fig. 9 shows how an air-diffusing divider 17 is fastened between the floor structure 4 and the climate screen 12 close to the inlet opening 18 to the climate zone 10.
  • An embodiment of the air diffuser 17 is shown on larger scale in Fig. 10 . This is provided with a number of openings or slots 29 which will distribute the airflow in a desired manner over the width of the climate zone.
  • the divider is bellows-shaped, it can be adapted to climate zones 10 of different or varying heights.

  • the flange 45 will be held pressed into the groove in the insulating panel 4 by means of the connecting and sealing rail 28 ( Fig. 3 ) which is inserted into the space between the flange 45 and a folded-over portion 47 thereof.
  • Fig. 12 shows a further embodiment of an air-distributing arrangement.
  • it consists of two angled profiles 48, 49 which are fastened to the floor structure 4 above the crawl space and, respectively, the climate screen 12, so that a narrow gap 50 is formed between the profiles 48 and 49.
  • the gap 50 By means of the gap 50, the airflow through the climate zone 10 can be made to spread out over the entire width of the zone.
  • the desired air distribution in the climate zone can be obtained.
  • the air-diffusing dividers according to Figs 10 , 11 and 12 can also be used for delimiting different climate zones, in which case they are not provided with openings, or they are mounted in such a manner that an intermediate gap is not formed.
  • Fig. 13 shows an alternative embodiment of a suspension arrangement for insulating panels which are to form a climate screen 12 according to Fig. 1 .
  • the arrangement comprises a hanging swingable suspension element 55 which is connected to a fastening plate 56 via a hinge 57.
  • the fastening plate 56 is intended to be mounted on the underside of the floor structure above the crawl space of the building.
  • the suspension element is provided with a number of openings 58 for receiving mounting elements 59, by means of which an upper and a lower rail-shaped mounting and sealing profile 60 and, respectively, 61 can be mounted at the desired mutual distance. This distance is adapted to the insulating panel to be secured between the profiles.
  • the climate screen can also be constructed from softer insulating panels 62 made of, for example, mineral wool, see Fig. 14 .
  • Foamed plastic strips 63 can then be arranged in the butt joints between the mineral wool panels.
  • Fig. 15 illustrates a further alternative suspension arrangement for insulating panels, which is also suitable for soft panels. It consists of an upper and a lower profiled rail 64 and, respectively, 65, one of which is provided with an upwardly projecting flange 66 which can be received in a gap between two downwardly projecting flanges 67, provided with friction teeth, of the other rail.
  • the rails can thus be locked relative to one another at the desired mutual distance which is adapted to the thickness of the insulating panel to be used.
  • Suspension is effected as previously by means of a swingable suspension element (not shown) which is fixed to the upper rail 64.
  • Fig. 16 shows a further alternative suspension arrangement which comprises upper and lower rails 68, 69 which are connected by means of a longitudinal cellular plastic core 70, the height of which is essentially the same as the thickness of the insulating panels to be used. Suspension from the floor structure is effected by means of height-adjustable screws which are guided through threaded holes 71 in the cellular plastic core 70.
  • Fig. 17 shows a specially shaped insulating panel 72 with milled-out edge portions 73 along two adjacent edges on one side and along the other two edges on the other side of the panel.
  • the panels have rounded cutouts 74 at the corners.
  • bobbin-like mounting elements 75 see Fig. 18 , which are suspended, by means of height-adjustable screws, from the floor structure of the building in positions for the rounded corner portions of the panels 72.
