Definitions

  • FR 2,287,557 A discloses a protection device according to the preamble of claim 1.
  • the shield that is to say the protective device according to claim 1, improves the comfort of the habitat in a very sunny area, allows a saving of energy on the use of air conditioners and this with an inexpensive investment because of the low cost of the materials used, makes habitat safer when exposed to high winds.
  • the invention is a device for protecting a wall which has the features of claim 1.
  • the shield consists of the doubling of the existing roof with galvanized and perforated sheet metal ( Figure 1 see the abstract). Shortly before laying, these sheets undergo cold rolling profiling similar to that of solid sheets for roofing and cladding.
  • the aim of the profiling is to give the sheet metal a rigidity sufficient to withstand different mechanical stresses such as its own weight, that of the assemblers, the forces of the wind, if necessary that of the snow, etc.
  • the assembly is particularly well suited to roofs covered with metal sheets, because in this case, it is done using spacers that are fixed at the fasteners of the sheets of the old roof. So that no additional preparation is needed.
  • This mechanism produces a continuous suction of the air located under the sheet which passes through the perforations and heats up in turn.
  • the air then plays a role of heat transfer fluid which exchanges heat with the sheet while flowing in contact with it.
  • the primitive roof under the perforated plate receives very little energy in the form of infrared radiation coming from the perforated plate. It receives mostly energy from solar radiation through the holes. The heat transmitted by this radiation diffuse throughout the old cover which leads to a moderate rise in temperature. When it is dark, the temperature of the old roof remains close to the temperature of the perforated sheets. When it is light in color, its temperature may be lower, up to two degrees below.
  • the model was made of laminated wood 12 mm thick. The wood was then tarred to resist humidity and insects.
  • the basic cover was made using a marine-blue coated sheet metal.
  • Table 1 presents an excerpt from the temperature measurements campaign carried out on the model and the experimental house during the "small summer of March” of the year 2006. These are temperatures actually measured and not averages.
  • the rows of the table correspond to a temperature record taken on the same day between 11 am and 12.30 pm
  • the conditions of sunshine and wind are substantially identical.
  • the average speed was between 5 and 6 m / s, with gusts of up to 10 m / s for about 5 to 10 seconds, but spaced from 2 to 15 minutes.
  • the faces on which the temperatures were measured are oriented towards the direction of the prevailing winds: full East for the model and East, North-East for the experimental house.
  • Temperatures in degrees Celsius are designated by the letter q .
  • column q is postponed ambient temperature measured with a mercury thermometer (accuracy 0.1 ° C). Q The measure was carried out in a shaded area and away from the wind.
  • the index (i) indicates that the temperature was measured inside the model (about 200 mm from the wall) or the experimental house (in the middle of the room), using a mercury thermometer .
  • the index (s) indicates a surface temperature measured using an infrared thermometer with an accuracy of 0.5 ° C to account for the dispersion of the measurements in the vicinity of a point.
  • the index (b) indicates the bottom of the model or a room (not air-conditioned) located on the first floor of the experimental house and, the index (c) designates the height of the model or the experimental house (ie the volume directly under the sheet).
  • Table 1 compares different shield configurations with the roof without a shield. Surveys on the model show the effectiveness of ventilation on a small surface (even without a shield).
  • bare sheet temperatures reach a peak: 62 ° C on the windward side and up to 75 ° C on the windward side (West side).
  • the gap between the old cover and the shield plate also plays a role, but there are interesting performances from the smallest gaps (80 mm). On the other hand, it is useless to increase this difference indefinitely, since beyond 200 mm, no further improvement in thermal performance is observed. In contrast, discrepancies more important can be considered for protection against high winds.
  • the scheme of the Figure 8 defines a spreader of the type used for the experimental house. For assembly convenience, it is recommended to arrange the spacer with the opening facing downwards.
  • the spacers must be adapted to the type of sheet metal roof to be doubled. We will therefore note common features (fixed ratings on the Figure 8 ), Common properties (described below), and variable dimensions of a type of sheet metal cover to the other (odds mainly, b and c Figure 8 ).
  • the dimension (a) must exceed from 15 to 20 mm (maximum and to be distributed between the two ends of the spacer) the distance between the axes of two successive vertices.
  • the base of the spacer may be bent under load.
  • the explanation is that the fastening screws must imperatively pass through the tops of these corrugations, and that there must be room inside the spacer to introduce the key that is used to tighten these screws.
  • Dimension (a) will be selected such that the spacer covers several corrugations while having a length equal to or greater than 300 mm. For each end of the spacer, a fixing screw will be placed at the level of the ridge apex closest to this end.
  • the second variable dimension is the dimension ( b ). This depends on the type of protection envisaged. The readings in Table 1 showed that the shield is already effective with a gap of 80 mm between sheets. The corresponding spacer will have greater mechanical strength.
  • the distance separating two successive spacers may be equal to approximately one and a half times the dimension (a) of the Figure 8 .
  • the length of 300 mm can be increased and even doubled without affecting the resistance of the whole in geographical areas with little exposure to strong winds. It will then be ensured that the distance between two spacers is less than or equal to the dimension (a) .
  • a simple nip of the spacer allows the maintenance of the cleat during assembly, but it can also strengthen this maintenance with a temporary adhesive film visible on the Figure 13 b.
  • the perforated plate is fastened using short conventional roofing screws (galvanized lag bolts, diameter 6 mm and 40 mm under head). These are the screws that provide the link cleat / spacer and the perforated sheet metal / cleat link.
  • a properly placed screw must pass through the perforated plate and the top of the spacer before sinking into the cleat.
  • lubricated screws using tire grease, for example.
  • the fabrication and assembly of the spacers is similar to those of Figures 12 and 13 .
  • the spacers and their cleats will simply be arranged in horizontal lines spaced 1.20 m apart. These spacers can have a rating a ( Figure 8 ) fixed at 300 mm and a horizontal space of 600 mm must be respected between two consecutive spacers.
  • Perforated sheets shall be fixed so that there is at least 300 mm of space between the base of the sheet and the floor.
  • we can limit the height reached by the plates so that their top when mounted just enter the shadow area projected by the roof at 9 o'clock. morning EST and 17 hours WEST.
  • the most unfavorable winds are those that have a strong component in a direction perpendicular to the lower edge of the roof.
  • the most exposed roofs in this case are roofs with two slopes. When the wind is oriented parallel to the roof, it generates relatively uniform pressure on the entire roof. The pressure losses caused by the perforated sheets reduce the flow velocities which, compared to a conventional roof, leads to a decrease in the pressure difference between the inside of the building and the outside of the roof.
  • the following two paragraphs are devoted to two-slope roofs exposed to winds perpendicular to the edge of the ridge.
  • the shield produces a decrease in the pressure difference between the inside and the outside of the house.
  • the leeward zone relatively calm compared to the previous one, is a zone of almost uniform low pressures.
  • the rollers generated by the passage of the top of the roof can even have a plating effect by folding the air on the roof. This effect is all the more marked as the wind is strong.
  • the perforated plate serving as ridge and the other sheets which make the connection between two sides of the shield must have free edges ( Figure 16 ), ie without fold.
  • connection of these ridge boards with the sheets of the shield body must be made using rivets (5 mm diameter for type A plates , 6 mm diameter for B-type plates), and this is done with at least one rivet per bank, as shown by the distribution of rivets on the shield of the experimental house visible in the photo of the Figure 16 .
  • the "heat and wind shield for the building” improves the comfort inside the buildings it covers by reducing the roof temperature and allowing to obtain a more homogeneous temperature in the different rooms. This naturally leads to saving the energy used for air conditioning.
  • ridge boards also play a key role in reducing the risk of wind stripping at the top of the roof.
