Abstract

A sheet-steel door, especially a fire-door, with a box structure (1) forming one large face of the door leaf and a cover (2) forming the other large side which is secured at its edge regions (3) to outwardly projecting strips (4) in the box-section edges parallel to the plane of the large faces, in which an edge section of the edge regions (3) of the cover (2) or of the edge strips of the box-section edges to form the contact region of a fold (7) is angled towards the box section (1) and extends over the connecting region (5). Said sheet-steel door is designed for substantially easier handling and a better joint between the box section and the cover in that the edge section (6) has a first bend forming a web (8), the width of which determines the top of the fold, and a second bend forming the contact region (9) which projects over the connecting region (5) at a distance of about the web width.

Description

Przedmiotem wzoru uzytkowego jest pokrywa drzwi z blachy stalowej, szczególnie drzwi ognioodpornych.Konstrukcje pokryw drzwi tego typu sa znane i to za¬ równo z zastosowaniem plaskiego polaczenia "na zakladke" pokrywy z konstrukcja skrzyniowa, jak równiez z zastosowa¬ niem ksztaltowego polaczenia "na zakladke". Przy zastosowa¬ niu polaczenia plaskiego, plaszczyzna pokrywy w obszarze styku z pasem krawedziowym, jest punktowo przyspawana do odgietego na zewnatrz brzegu konstrukcji skrzyniowej pasa krawedziowego, tak, ze uzyskuje sie arkusz drzwi o odpo¬ wiedniej grubosci zwiazanej z glebokoscia konstrukcji skrzyniowej. Pokrywa drzwi zawiera wczesniej wykonane przedluzenia, które wystaja poza pas krawedziowy konstruk¬ cji skrzyniowej, w postaci segmentów krawedziowych, które po spawaniu punktowym zagiete sa o 180° i nalozone na pas krawedziowy konstrukcji skrzyniowej. W ten sposób w obsza¬ rze polaczenia zakladkowego uzyskuje sie potrójne zalamanie blach o nieduzej grubosci, przy czym zagiete segmenty kra¬ wedziowe pokrywy drzwi oslaniaja strefe spawania punktowe¬ go, które stanowi polaczenie miedzy pasami krawedziowymi konstrukcji skrzyniowej i obszarami brzegowymi pokrywy- 2 - drzwi.Znana konstrukcja pokrywy drzwi stalowych wykonanych z zastosowaniem ksztaltowego polaczenia "na zakladke" w obszarze brzegowym, wystajacym poza konstrukcje skrzynio¬ wa drzwi, zawiera zagiete pod katem prostym zebro,i pola¬ czony z nim, zagiety równiez pod katem prostym zaczep, któ¬ ry pokrywa pasy krawedziowe konstrukcji skrzyniowej, i swa wolna krawedzia dochodzi do linii zagiecia pasa krawedzio¬ wego konstrukcji skrzyniowej. Tu znajduje sie spoina, co jest niekorzystne ze wzgledu na mozliwosci narzedzi spawal¬ niczych i ugar elektrody.W opisie polskiego prawa ochronnego nr 53890 przedsta¬ wiono drzwi o konstrukcji skrzyniowej, w których krawedz pokrywy polaczonej spoina punktowa z konstrukcja drzwi za¬ gieta jest w ksztalcie korytka.Przedmiotem wzoru uzytkowego jest konstrukcja pokrywy drzwi z blachy stalowej, szczególnie drzwi ognioodpornych o konstrukcji skrzyniowej, w której zakonczenie obrzeza przylaczone od zewnetrznej strony do strefy zlacza, jest podwójnie zagiete tworzac obszar przylgowy zakonczenia ksztaltowego wystajacego ponad konstrukcje skrzyniowa drzwi i oslaniajacego strefe zlacza.Istota wzoru polega na tym, ze segment krawedzi pokry¬ wy zawiera pierwsze zagiecie w postaci zebra okreslajacego swoja szerokoscia grubosc ksztaltowego polaczenia "na zaklad¬ ke" i drugie zagiecie stanowiace zaczep, które na calej sze¬ rokosci •zebra oslania spoine punktowa. Przy zagieciu tworza¬ cym zaczep ksztaltowego zagiecia, uksztaltowane jest trzecie zagiecie w postaci krawedzi usztywniajacej skierowanej w kie-- 3 - runku spoiny, przy czym kat zawarty miedzy krawedzia usztyw¬ niajaca i zaczepem jest mniejszy niz 90°.Dzieki zastosowania rozwiazania wedlug wzoru, uzyskuje sie to, ze mozliwe jest polaczenie miedzy pokrywa i kons¬ trukcja skrzyniowa, i ze poprzez proste nalozenie konstruk¬ cji skrzyniowej na pokrywe, lub odwrotnie, unika sie uciaz¬ liwego dopasowywania konstrukcji skrzyniowej i wstepnie uk¬ sztaltowanej pokrywy.Przedmiot wzoru zostal przedstawiony na rysunku, na którym przedstawiono schematycznie wycinek przekroju po¬ krywy drzwi stalowych.Obrzeze 2. pokrywy 2 konstrukcji skrzyniowej drzwi sta¬ lowych 1 wystajace na zewnatrz strefy zlacza, tworzace seg¬ ment 6. krawedzi, jest podwójnie zagiete, aby utworzyc pola¬ czenie "na zakladke", przy czym segment _6 obejmuje zebro .8. przylaczone do strefy zlacza i polaczony z nim pod katem prostym zaczep _2_, zakonczony krawedzia usztywniajaca 10, skierowana w kierunku spoiny punktowej ,5, przy czym krawedz 10 zagieta jest pod katem rozwartym w stosunku do zaczepu 9. Zebro _8 decydujace o grubosci zagiecia ksztaltowego, w fazie przygotowania do polaczenia, jest zagiete w stosun¬ ku do powierzchni drzwi o kat mniejszy niz 90°, dzieki cze¬ mu, strefa zlacza miedzy pokrywa i konstrukcja skrzyniowa jest latwo dostepna dla spawarki punktowej. Po wykonaniu spoiny segmentu L, obrzeze 3. pokrywy 2 jest zaginane dalej, az do uzyskania ostatecznego ksztaltu, to znaczy do momen¬ tu, gdy zebro _8 bedzie usytuowane pod katem prostym do plaszczyzny pokrywy. Konstrukcja pokrywy drzwi stalowych przedstawiona na rysunku, chociaz w konstrukcji tej zasto-- 4 - sowano najprostsze i najkorzystniejsze produkcyjne techniki manipulacyjne i spawalnicze, daje jednak pelna oslone stre¬ fy zlacza.58S&2J T-36 678/MI PCT/DE95/01144 PLThe object of the utility model is a door cover made of steel sheet, especially fire-resistant doors. The designs of the door covers of this type are known, both with the use of a flat "overlap" connection between the cover and the box structure as well as with the use of a shaped "overlap" connection. ". When a flat joint is used, the plane of the cover in the area of contact with the edge flange is spot welded to the outwardly bent edge of the box structure of the edge band, so that a door sheet of the appropriate thickness is obtained, related to the depth of the box structure. The door cover includes pre-made extensions which extend beyond the edge of the box structure in the form of edge segments which are bent by 180 ° after spot welding and placed over the edge of the box structure. In this way, in the area of the lap joint, a triple break of thin sheets is obtained, with the bent edge segments of the door cover covering the spot weld zone which is the joint between the edge strips of the box structure and the edge areas of the door cover. The well-known structure of the cover of steel doors made with an overlap-shaped joint in the edge area extending beyond the door cantilever structure includes a rib which is bent at a right angle and is connected to it, also bent at a right angle, which The cut covers the edge strips of the box structure, and its free edge comes to the fold line of the edge strip of the box structure. There is a weld here, which is disadvantageous due to the possibilities of welding tools and electrode wear. The description of the Polish protection law No. 53890 presents a box-type door, in which the edge of the cover is connected by a point weld with the door structure bent in The object of the utility model is the construction of the door cover made of steel sheet, especially fireproof doors with a box structure, in which the edge of the perimeter connected from the outside to the joint zone is double bent to form the rebate area of the shape end protruding above the door box structure and enclosing the joint zone The essence of the pattern is that the segment of the cover edge comprises a first fold in the form of a zebra defining its width, the thickness of the overlapped joint, and a second fold constituting a hook, which over the entire width gathers the spot weld. In the case of the bend forming the buckle of the shape bend, a third bend is formed in the form of a stiffening edge directed in the direction of the weld, the angle between the stiffening edge and the catch being less than 90 °. this is achieved that a connection between the lid and the box structure is possible and that by simply applying the box structure to the lid or vice versa, the cumbersome fit of the box structure and the pre-folded lid is avoided. in the drawing, which schematically shows a cross-sectional view of a steel door cover. The edge of the 2nd cover 2 of the box structure of the steel door 1 projecting outside the joint zone, forming the 6th edge segment, is bent twice to create a joint overlap, with segment _6 covering the rib .8. attached to the joint zone and connected to it at a right angle, the hook _2_, ended with a stiffening edge 10, directed towards the point weld, 5, the edge 10 being bent at an obtuse angle in relation to the hook 9. Zebro _8 determining the thickness of the shape bend, in the phase of preparation for joining, it is bent in relation to the door surface with an angle less than 90 °, so that the joint zone between the cover and the box structure is easily accessible by a spot welder. After the weld of the L segment, the rim 3 of the cover 2 is further folded until the final shape is obtained, that is, until the rib 8 is at right angles to the cover plane. The structure of the steel door cover is shown in the drawing, although the simplest and the most advantageous production handling and welding techniques were used in this structure, it provides a complete shielding of the joint zones 58S & 2J T-36 678 / MI PCT / DE95 / 01144 PL
