Abstract

A metallic roofing tile is proposed for cleaning and maintenance of cleanliness of building roofs which reacts on contact with moisture through its shaped reactive surface (2) with elevated bulges (3) and openings (4) where the openings (4) of the bulges (3) are inclined in the opposite direction (A) to the flow of water. Thus, the access of water flowing down the roof slope along their reactive surfaces (2) to the underside (5) of the metallic roof tile is increased, and a higher efficiency is achieved.

Description

Kovinska strešna ploščaMetal roof panel

Izum se nanaša na kovinsko strešno ploščo za čiščenje in vzdrževanje čistoče streh zgradb, zlasti čiščenje obraščenosti z rastlinjem ali umazanije iz okolice, sestoječo iz kovine, ki reagira v povezavi z vlago, pri čemer je kovinska strešna plošča s štancanjem izdelana iz ploščatega materiala in obsega izoblikovane reakcijske ploskve s povišanimi izboklinami in odprtinami.The invention relates to a metal roof plate for cleaning and maintaining the cleanliness of the roofs of buildings, in particular the cleaning of fouling by vegetation or dirt from the environment, consisting of metal that reacts in connection with moisture, the metal roofing plate being made of plate material and scope formed reaction surfaces with elevated projections and openings.

Tovrstna priprava za zaščito kritin zgradb pred obraščenostjo z rastlinjem, zlasti mahom in lišaji, je znana iz DE 44 13 119 C2 istega prijavitelja. Z izdelavo kovinske strešne plošče iz ploščatega materiala s štancanjem nastane tu možnost, da se da kovinsko strešno ploščo na enostaven način prilagoditi obliki strešniku, uporabljenem pri pokrivanju strehe. Zlasti se da pri tem spodaj ležečo zaokrožitev izdelati sočasno s štancanjem, tako da se v primerjavi z enostavno bakreno pločevino dobi optično ustrezno zasnovo, zlasti pa se reakcijske ploskve v veliki meri izkoristi za odtekajočo vlago med dvema vrstama strešnih plošč. Nadalje se pridobi enostavnejšo montažo kovinske strešne plošče, kajti po zunanji obliki s strešnikom ujemajočo se kovinsko strešno ploščo se da na enostaven način potisniti med posamezne vrste strešnikov.Such preparation for the protection of building coverings against fouling by vegetation, in particular moss and lichen, is known from DE 44 13 119 C2 of the same applicant. The manufacture of a metal roof panel made of punching material creates the possibility that the metal roof panel can be easily adapted to the shape of the roofing tile used. In particular, the bottom rounding can be made simultaneously with punching so that an optically appropriate design is obtained in comparison with a simple copper sheet, and in particular the reaction surfaces are largely used for the drainage moisture between two types of roof panels. Furthermore, a simpler mounting of the metal roofing plate is obtained, since the metal roofing plate that matches the exterior with the tile can be easily moved between individual types of roofing.

Poleg tega se z izdelavo s štancanjem posameznih kovinskih strešnih plošč nasproti položeni, gladki bakreni pločevini pridobi enostavno možnost, da je na zunanjem robu vsake posamične strešne plošče vsakokrat zasnovana naokoli potekajoča žmula, ki zmanjša hitro odtekanje vlage in s tem zviša reakcijski čas med vlago in kovinsko strešno ploščo. Pri tem se lahko pri izdelavi kovinske strešne plošče s štancanjem v tisti polovici kovinske strešne plošče (reakcijska površina), ki leži navzdol glede na smer odtekanja vode, vtisne izbokline, tako da mora odtekajoča vlaga opraviti karseda dolgo pot, sočasno pa se zagotovi dobro porazdelitev vlage po strešni površini. Poleg tega lahko obenem s štancanjem in zvišanimi (izbočenimi) iztisnjenimi izboklinami na njihovih naj višjih mestih predvidi odprtine v obliki zarez, s čimer lahko tekočina tudi na spodnji strani kovinske strešne plošče reagira s spodnjo stranjo kovine. S tem se doseže podvojitev reakcijske površine, tako da se glede na znani sistem ob višji učinkovitosti da doseči znatno zmanjšanje števila vrst, ki se naj jih pokrije. Kot zareza zasnovane, ozke odprtine pa dovoljujejo sorazmerno majhen dostop vlage na spodnjo stran kovinske strešne plošče.In addition, by punching individual metal roof panels against a laid-in, smooth copper sheet, it is easy to have a peripherally shaped bead on the outside edge of each individual roof panel, which reduces the rapid drainage of moisture and thereby increases the reaction time between moisture and metal roof panel. In doing so, when the metal roof panel is stamped in the half of the metal roof panel (reaction surface) lying down with respect to the direction of water drainage, the projections can be imprinted so that the effluent has to travel as long as possible while ensuring good distribution. moisture over the roof surface. In addition, at the same time as punching and elevated (convex) extrusions, they can provide notches in their highest positions, allowing the liquid to react with the underside of the metal on the underside of the metal roof panel. This results in a doubling of the reaction surface so that, given the known system, a higher reduction in the number of species to be covered can be achieved with higher efficiency. Notch-shaped, narrow openings allow relatively low moisture access to the underside of the metal roof panel.

Za zaščito strešne kritine pred obraščenostjo z mahom, ki se pojavi v teku let, so po DE-A41 30 365 nadalje v vidnem območju strešne površine tako nameščene bakrene pločevine, da pridejo v stik z deževnico, odtekajoča deževnica pa se pod bakrenimi pločevinami preliva po karseda veliki površini strešne kritine. Deževnica topi pri tem sestavine, zlasti ione, iz bakrenih pločevin, ki učinkujejo proti poraslosti z rastlinjem, zlasti z mahom in lišaji, po betonskih ali opečnatih strešnih ploščah. Bakrene pločevine so pri tem na prednosten način zasnovane v obliki slemenskih pokrovov in razporejene vzdolž slemena, da bi odtekajoča vlaga lahko odtekala po celotni strešni površini. Alternativno se lahko namesto obokanih slemenskih pokrovov, ki jih je težko izdelati, v območju dvokapnice namesti tudi enostavne pasaste bakrene pločevine.In order to protect the roof covering from fossil moss occurring over the years, according to DE-A41 30 365, copper sheets are placed in the visible area of the roof surface so that they come in contact with rainwater and the draining rainwater flows over the copper sheets. as large as possible on the large roof surface. Rainwater melts constituents, in particular ions, from copper sheets, which have an anti-overgrowth effect on vegetation, especially moss and lichen, on concrete or brick roof tiles. Preferably, the copper sheets are designed in the form of ridge covers and arranged along the ridge in order to allow the drainage moisture to flow out over the entire roof surface. Alternatively, simple striped copper sheets may be installed in the area of the bifurcation instead of arched, difficult-to-manufacture ridge covers.

Pri tem pa je pomanjkljivo, da je izdelava v izvedbi kot slemeski pokrov zaradi potrebnih upogibnih del in prilagajanja slemenkim pokrovom zelo zahtevna. Alternativno k temu predvideno položeno, pasasto bakreno pločevino v območju dvokapnice je sicer sorazmerno enostavno izdelati, tako da se bakreno pločevino odvije s svitka, vendar ostane med dvema drug drugemu sledečima nizoma strešnih plošč le majhna efektivna površina bakra, tako da se mora za ustrezno učinkovitost proti obraščenosti strešnih površin z rastlinjem položiti množico tovrstnih nizov bakrenih trakov. S tem pa se v celoti zopet dobi visoko obremenitev s stroški. Poleg tega se tovrstne bakrene trakove težko namesti, zlasti pri dodatnem opremljanju že obstoječih streh, kajti bakrene trakove se mora položiti in pritrditi med nize strešnih plošč, s čimer se mora glede na dolžino uporabljenega bakrenega traku odstraniti večje število strešnih plošč.However, it is not a disadvantage that the construction in the form of a ridge top is very demanding due to the necessary bending work and adaptation to the ridge covers. Alternatively, the laid copper strip in the area of the bifurcation is relatively easy to fabricate by unscrewing the copper plate from the coil, but only a small effective copper surface remains between two successive rooftops so that for adequate efficiency to lay a series of such copper strips against the vegetation of the roof surfaces with vegetation. This, in turn, again results in a high cost burden. Moreover, such copper strips are difficult to install, especially when retrofitting existing roofs, since copper strips must be laid and secured between rows of roof panels, thus removing a larger number of roofing panels depending on the length of the copper strip used.

Iz tega sledeča je naloga izuma nadalje izboljšati kovinsko strešno ploščo za čiščenje in vzdrževanje čištoče na strehah zgradb tako glede učinkovitosti kot rokovanja.From this, it is further the object of the invention to further improve the metal roof panel for cleaning and maintaining cleanliness on the roofs of buildings in terms of both efficiency and handling.

Ta naloga je rešena s kovinsko strešno ploščo po značilnostih 1. patentnega zahtevka.This task is solved by a metal roof panel according to the features of claim 1.

Z nagibom odprtin izboklin nasproti smeri odtekanja vode, torej k slemenu, se omogoči izboljšani vstop vode k spodnji strani kovinske strešne plošče. S tako izboljšanim omočenjem spodnje strani kovinske strešne plošče z vlago se omogoči izboljšan izkoristek spodnje strani strešnih plošč, tako da s tem naraste učinek čiščenja na strehi zgradbe. S tem zlasti ostane sorazmerno veliko zaostale vlage na spodnji strani kovinske strešne plošče, s čimer se poveča izločevanje ionov kovine.By tilting the openings of the projections opposite to the direction of the drainage of the water, that is to the ridge, the improved entry of water to the underside of the metal roof panel is enabled. The wetting of the underside of the metal roof panel with moisture improves the utilization of the underside of the roof panels so that the cleaning effect on the roof of the building is increased. This, in particular, leaves a relatively large amount of residual moisture on the underside of the metal roof panel, thereby increasing the excretion of metal ions.

Poleg tega se s tistimi odprtinami izboklin, ki so obrnjene proč od opazovalca strešne plošče, stoječega na tleh, dobi enakomernejši videz kovinske strešne plošče. Nadalje se z odprtinami, nagnjenimi k smeri odtekanja vode, v veliki meri izognemo srhu pri štancanju, tako da s se tem tudi brez zahtevne dodatne obdelave zmanjša nevarnost poškodb in s tem izboljša rokovanje.In addition, those bumper openings facing away from the observer of the roof panel standing on the floor give a more even look to the metal roof panel. Furthermore, openings inclined to the direction of water drainage largely avoid puncture, thus reducing the risk of injury even without demanding additional treatment, thereby improving handling.

Nadaljnje prednostne izvedbe so predmet podzahtevkov. Bistvenega pomena je pri tem tudi predoksidacija kovinske strešne plošče z ultrazvočnim čiščenjem in/ali razmastitvijo s kemičnim čistilom, npr. lugom ali kislino. S tem se aktivira bakrove ione na površini kovinske strešne plošče, tako da kovinska strešna plošča lahko učinkuje že neposredno po postavitvi na streho zgradbe. To predoksidacijo se pri tem prednostno izvede z odstranitvijo sicer na traku bakra nahajajoče se valjalne masti tako na zgornji kot tudi na zgornji strani kovinske strešne plošče.Further preferred embodiments are subject to sub-claims. It is also essential to pre-oxidize the metal roof panel by ultrasonic cleaning and / or degreasing with a chemical cleaner, e.g. alkali or acid. This activates the copper ions on the surface of the metal roof panel so that the metal roof panel can take effect immediately after being erected on the roof of the building. This pre-oxidation is preferably accomplished by removing the roller grease present on the copper strip, both on the upper and upper sides of the metal roof panel.

Poleg tega se da sočasno s štancanjem na zgornji strani kovinske strešne plošče iztisniti žmulaste opore, ki so zasnovane kot opore za nad njimi ležeče strešnike. S tako ustvarjenim ozkim vmesnim prostorom se poleg tega dobi možnost zračenja opečnih ali betonskih strešnih plošč streh zgradb.In addition, at the same time as the stamping on the upper side of the metal roofing plate, bulbous supports can be extruded, which are designed as supports for the roof tiles above them. The narrow space created in this way also gives the possibility of ventilation of the brick or concrete roof tiles of the roofs of buildings.

V nadaljevanju je prednostni izvedbeni primer pobliže pojasnjen in opisan s pomočjo skic. Pri tem kaže sl. 1 kovinsko strešno ploščo, zasnovano v t.i. formatu bobrovec, in v pogledu od zgoraj; sl. 2 najbolj spodnje območje kovinske plošče s sl. Iv prečnem prerezu in povečanem prikazu;In the following, the preferred embodiment is explained and described in more detail with reference to the drawings. In this respect, FIG. 1 metal roof panel designed in e.g. beaver format, and in top view; FIG. 2 is the bottom region of the metal plate of FIG. Iv cross section and enlarged view;

sl. 3 povečan izsek v pogledu od zgoraj po sl. 1; in sl. 4 prikaz vzdolžnega prereza za ponazoritev vgraditvenega položaja kovinske strešne plošče med dvema nizoma strešnih plošč (strešniki ali iz betona).FIG. 3 is an enlarged top view in FIG. 1; and FIG. 4 shows a longitudinal section to illustrate the installation position of a metal roof panel between two sets of roof panels (tiles or concrete).

Na sl. 1 je predstavljena kovinska strešna plošča v pogledu od zgoraj, ki je zasnovana z naokoli potekajočo žmulo 1 (prim. tudi sl. 2) v obliki t.i. bobrovec strešne plošče. Pri tem se kovinsko strešno ploščo vzdolž naokoli potekajočega žmulastega območja 1 izseka iz ploščatega materiala, zlasti bakrene pločevine, pri čemer se sočasno v teku štancanja vtisne naokoli potekajoče žmulasto območjo 1. Poleg tega se v spodnji polovici s križi označene reakcijske ploskve 2, kije v vsavljenem stanju kovinske strešne plošče (prim. sl. 4) obrnjena proč od površine strehe, vtisne množico (tu okoli 150 na vsako kovinsko strešno ploščo) navzven zasnovanih izboklin 3 oz. iztisne iz reakcijske ploskve 2.In FIG. 1 is a top view of a metal roof panel, which is designed with an extending bead 1 (see also Fig. 2) in the form of a so-called. roof panel beaver. In doing so, the metal roof panel extends along the extruded bulbous area 1 from the flat material, in particular copper sheets, while simultaneously extruding the bulbous area 1 during the punching process. the inflated state of the metal roof panel (cf. Fig. 4), facing away from the roof surface, impresses the crowd (here about 150 on each metal roof panel) outwardly projecting projections 3 or. protrude from reaction surface 2.

V smislu novosti so pri tem zamaknjeno od najvišjih točk iz reakcijske ploskve 2 iztisnjenih izvoklin 3 predvidene asimetrično razporejene odprtine 4, zlasti v obliki elipsastih izrezov (prim. sl. 3). S to zasnovo reakcijske ploskve 2 v obliki dvignjenih, iztisnjenih izboklin 3 se po eni strani zavira odtekanje tekočine, tako da mora odtekajoča vlaga (deževnica, snežnica ipd.) opraviti karseda dolgo pot med in vzdolž izboklin 3, po drugi strani pa se zagotovi enakomerno porazdelitev po reakcijski ploskvi 2. S tem se zlasti pri vetru in močnih sunkih vetra doseže, da odtekajoča vlaga karseda dolgo reagira s kovino in s tem izluži bakrove ione iz kovinske strešne plošče, ki preprečujejo rast na strehah zgradb in izvajajo čistilen učinek na strešno površino.In terms of novelty, asymmetrically arranged openings 4, especially in the form of ellipse cut-outs, are provided away from the highest points from the reaction surface 2 of the extruded recesses 3, in particular in the form of elliptical cutouts (cf. Fig. 3). This design of reaction surface 2 in the form of raised, extruded protrusions 3 inhibits the drainage of fluid on the one hand, so that the effluent (rainwater, snowflake, etc.) has to travel as long as possible between and along the protrusions 3 and, on the other hand, is provided uniformly. 2. In particular, in the case of wind and strong wind gusts, the outflow moisture reacts as much as possible with the metal, thereby extracting copper ions from the metal roof panel, which prevent growth on the roofs of buildings and exert a cleaning effect on the roof surface. .

Z asimetrično razporejenimi, nasproti smeri A odtekanja vode nagnjenimi odprtinami 4 se v smislu novosti poleg tega doseže, da velik delež odtekajoče tekočine lahko ciljno sega od zgornje strani 6 k spodnji strani 5 kovinske strešne plošče, kjer lahko reagira s kovinsko površino na spodnji strani 5. S tem se dobi podvojitev reakcijske površine, kajti tudi pri megli ali majhnih padavinah ostane vlaga zaradi kapilarnega učinka na spodnji strani 5 na strehi zgradbe ležeče kovinske strešne plošče, s čimer se do nadaljnjega odtekanja znatno poveča reakcijski čas vlage in kovinske strešne plošče.By means of asymmetrically arranged openings 4 opposite to the direction of the drainage of water, the openings 4, in terms of novelty, further achieve that a large proportion of the draining fluid can reach from the top 6 to the bottom 5 of the metal roof panel where it can react with the metal surface on the bottom 5 This results in a doubling of the reaction surface, since even in the case of fog or light rainfall, moisture due to the capillary effect on the underside 5 on the roof of the metal roof panel building, which significantly increases the reaction time of moisture and the metal roof panel until further drainage.

Na sl. 2 in 3 je povečano predstavljena prednostna zasnova k površini 6 iztisnjenih izboklin 3 z odprtinami 4, izsekanih pri štancanju oz. vtiskanju. Tu je očitna zasnova glede na središčnico izboklin 3 asimetrično razporejenih odprtin 4 v obliki lovilnega žepa, ki omogočajo zlasti učinkovit vstop vode vzdolž smeri A odtekanja vode k spodnji strani 5. Pri tem lahko asimetrično razporejena odprtina 4 poteka celo do zgornje strani 6, kot je to ponazorjeno s črtkano črto.In FIG. 2 and 3, a preferred embodiment of the surface design 6 of the extruded projections 3 with the openings 4 incised during the punching or the extrusion is presented. embossing. Here is an obvious design with respect to the center line of the projections 3 of the asymmetrically arranged openings 4 in the form of a trapping pocket, which allow in particular the efficient entry of water along the direction A of the drainage of water to the underside 5. In this way, the asymmetrically arranged opening 4 can extend even to the upper side 6, this is illustrated by the dashed line.

Na sl. 4 je predstavljena kovinska strešna plošča v vstavljenem položaju med dva niza strešnikov 8, pri čemer lahko strešniki 8 sestoje tudi iz betonskih formatiranih plošč. Pri tem se kot prvo vidi razpored v spodnji polovici kovinske strešne plošče nahajajoče se, izoblikovane reakcijske ploskve 2, kot tudi po zunanjem robu naokoli potekajočo žmulo 1. Nadalje je pomembno v zgornji polovici, torej nad na sl. 1 prikazanim reakcijskim poljem 2, povišano iztisnjena dodatna žmulasta opora 7, na katero se lahko opira na njej nahajajoči se strešnik 8. Med naokoli potekajočo žmulo 1 in žmulasto oporo 7 je tako vsakokrat zasnovan ploski vmesni prostor 9, s katerim se doseže izboljšano zračenje streh zgradb.In FIG. 4 shows a metal roof panel in an inserted position between two sets of tiles 8, wherein the tiles 8 may also consist of concrete formatted panels. The first is the arrangement in the lower half of the metal roof panel of the formed, formed reaction surface 2, as well as along the outer edge of the extending beetle 1. It is further important in the upper half, that is, above FIG. 1 to Reaction Box 2 shown, an elevated extruded extra bulbous support 7 on which the tile 8 can rest on it. A planar intermediate space 9 is thus designed in each case between the extending bulb 1 and the bulbous support 7, in order to achieve improved roof ventilation. buildings.

Ti vmesni prostori 9 so pri tem visoki le nekaj milimetrov, tako da je v povezavi s sorazmerno veliko dolžino teh kanalov podana zadostna zaščita pred z vetrom gnano vlago, ki je z močnimi sunki vetra gnana vzdolž strešne površine. Pri tem pa je določena mera v vmesne prostore 9 potisnjene vlage celo zaželena, kajti s tem se tudi z zgornjim nizom strešnih plošč 8 pokrito zgornjo površino kovinske strešne plošče izrabi kot reakcijsko ploskev.These intermediate spaces 9 are only a few millimeters high, so that, in connection with the relatively large length of these channels, sufficient protection against wind-driven humidity is provided, driven by strong gusts of wind along the roof surface. However, a certain degree of even moisture is suppressed into the intermediate spaces 9 of the repressed moisture, since this also utilizes the upper surface of the metal roof panel with the upper set of roof panels 8 to be used as a reaction surface.

Učinkovitost se da nadalje povečati s predoksidacijo, zlasti s krajšim potapljanjem kovinske strešne plošče v kemična čistila na osnovi luga ali kisline in ultrazvočnim čiščenjem, tako da se izognemo siceršnjemu razpoložljivemu času aktiviranja do učinkovanja izluženja ionov kovin.Efficiency can be further enhanced by pre-oxidation, in particular by short immersion of the metal roof panel in alkaline or acid-based chemical cleaners and ultrasonic cleaning, so as to avoid the otherwise available activation time until the metal ion leaching effect.
