TEHNIČNI PROBLEMTECHNICAL PROBLEM

Obstajal je problem, kako pri dokončno pokriti strehi zagotoviti kar največjo tesnost proti vdiranju vlage in vetra pod kritino.There was a problem of how to maximize the leakage of moisture and wind under the roof when the roof was completely covered.

STANJE TEHNIKEBACKGROUND OF THE INVENTION

Strešni pokrivni elementi te vrste so znani npr. iz AT 278 321. Tesnilne razmere in naleganje tam opisanih strešnih pokrivnih elementov na strešnem tesnilnem elementu, ki je razporejen spodaj, pa ni optimalno, tako da v kritino vdirata vlaga in veter.Roof cover elements of this type are known e.g. from AT 278 321. However, the sealing conditions and the mounting of the roof covering elements described therein on the roof sealing element arranged below are not optimal, so that moisture and wind invade the roof.

OPIS REŠITVE PROBLEMADESCRIPTION OF THE PROBLEM SOLUTION

Po izumu se pri strešnem pokrivnem elementu uvodoma omenjene vrste predvideva, da je debelina predmetnega elementa za valovito spodnjo površino elementa, merjena na temenu prečnega rebra, ki je najbolj oddaljeno od vznožnega rebra, malenkostno, do kvečjemu 6%, manjša od debeline elementa na vznožnem rebru in da je višina reber, razporejenih med vznožnim in od le-tega najbolj oddaljenim rebrom, manjša od višine prečnega rebra, ki je od vznožnega najbolj oddaljeno. Prečno rebro, katerega višina je malenkostno manjša od višine vznožnega rebra in ki je od slednjega najbolj oddaljeno, ne omogoča naseda, hkrati pa med seboj in vznožnim rebrom omejuje prostor, ki služi kot vrtinčna komora za vdirajoče zračne tokove. Vdirajoči zračni tok se tam umiri, vdirajoča vlaga pa, ker ni kapilarnosti, odteka po spodnjem, prekritem strešnem elementu. TlakAccording to the invention, in the roof covering element of the above mentioned type, it is assumed that the thickness of the object element for the undulating lower surface of the element, measured at the top of the transverse rib, farthest from the foot rib, is slightly to 6% less than the thickness of the foot element and that the height of the ribs arranged between the base and outermost ribs is less than the height of the transverse rib farthest from the base. A transverse rib, the height of which is slightly smaller than the height of the foot rib, and which is farthest from the latter, does not allow for a seat, while limiting the space between the foot and the bottom rib, which serves as a vortex chamber for intruding air currents. The intruding air stream calms down there, and the ingress moisture, because there is no capillarity, drains down the lower, covered roof element. Pressure

- 3 vdirajočega zraka se razblini, kar pomeni izravnavo tlakov med vrtinčno komoro in podstrešjem. Prisotnost nadaljnjega prečnega rebra (reber) nižje višine od višine preostalih reber izboljšuje učinek vrtinčne komore in s tem tesnilni učinek med elementoma strešnega prekritja v samem prekrivnem območju. Pri tem je prednostno debelina strešnega prekrivnega elementa čez temena vmesnih prečnih reber, nahajajočih se med vznožnim in od vznožja najbolj oddaljenim prečnim rebrom, za okoli 8 do 16%, prednostno okoli 10 do 12% manjša od debeline elementa pri vznožnem rebru.- 3 intruding air breaks out, which means balancing the pressure between the vortex chamber and the attic. The presence of a further lateral rib (ribs) of lower height than the height of the remaining ribs enhances the effect of the vortex chamber and thus the sealing effect between the elements of the roof covering in the overlay area itself. Preferably, the thickness of the roof overlay is over about 8 to 16%, preferably about 10 to 12%, less than the thickness of the element at the lateral rib over the tops of the intermediate transverse ribs between the base and the farthest transverse ribs.

Tokovne razmere glede zatesnitve in minimiziranja prepiha se še nadalje izboljšajo, če je debelina pokrivnega elementa nad dnom žlebov med vznožnim in nadaljnjimi prečnimi rebri oz. med slednjimlin prečnim rebrom, ki je od vznožnega najbolj oddaljeno, enaka.The current conditions regarding sealing and draft minimization are further improved if the thickness of the cover element above the bottom of the grooves is between the lateral and further transverse ribs, respectively. between the latter and the transverse rib farthest from the foot, the same.

Izum v nadaljnjem opisujemo na osnovi izvedbenega primera, predstavljenega v priloženem listu s samcato skico.The invention will now be described on the basis of the embodiment shown in the accompanying single sketch sheet.
