Description

überliegenden Eckbereichen Scharnierbolzen aufnehmende öffnungen angeordnet sind, wodurch die Anbringung besonderer Scharniere entfällt.Overlying corner areas are arranged hinge pin receiving openings, whereby the attachment special hinges are not required.

Die Erfindung wird nachfolgend an Hand der zeichnerischen Darstellung eines Ausführungsbeispieles näher erläutert. Es zeigtThe invention is explained below with reference to the graphic representation of an exemplary embodiment explained in more detail. It shows

F i g. 3 im Teilschnitt den Verschluß.F i g. 3 the closure in partial section.

In den Figuren ist der als Schale 2 mit hochgebogenen Rändern 3 ausgebildete Verschluß 1 aus dünnem Blech dargestellt.In the figures, the closure 1, designed as a shell 2 with upturned edges 3, is made of thin Sheet metal shown.

Diese für sich noch nicht ausreichend steife Schale 2 wird durch das Stützprofil 4 gemäß F i g. 2 ausgesteift, indem dieses einfach in die Schale 2 eingelegt und an einigen Stellen festgepunktet wird, und zwar nachdem vorher entweder eine Brennerplatte 6 und ein Wärmedämmblock 5 eingelegt worden sind, die damit gleichzeitig von dem Stützprofil 4 gehalten werden. Das Stützprofil 4 besteht im Querschnitt aus einem äußeren großen U-Profil7 und einem damit verbundenen inneren kleinen U-Profil8. Die Brennerplatte 6 muß natürlich nicht in ihrer Fläche der ganzen freien Fläche zwischen dem äußeren U-Profil 7 entsprechen, sondern kann auf die Brennflanschbreite abgestimmt sein. Aus Gründen einer guten Halterung soll sie jedoch mit mindestens zwei Seiten bis an das U-Profil 7 heranreichen.This shell 2, which is not yet sufficiently rigid in itself, is supported by the support profile 4 according to FIG. 2 stiffened by simply inserting it into the shell 2 and pinpointing it in some places, and although after either a burner plate 6 and a thermal insulation block 5 have been inserted beforehand, which are thus held by the support profile 4 at the same time. The support profile 4 consists of in cross section an outer large U-profile7 and an associated inner small U-profile8. the Burner plate 6 must of course not in its area of the entire free area between the outer U-profile 7 correspond, but can be matched to the width of the focal flange. For the sake of one However, it should reach up to the U-profile 7 with at least two sides for good support.

Im inneren U-Profil 8 des Stützprofils 4 ist eine Dichtung 9 eingelegt, die sich dann in Schließstellung auf einen Stegrahmen 15 der Kesselvorderwand 13 auflegt. Wie aus Fig. 3 erkennbar, werden die Randbereiche 5' des Wärmedämmblockes 5 vom inneren U-Profil 8 übergriffen, so daß dieses den WärmedämmblockS hält. Je nach den Erfordernissen derIn the inner U-profile 8 of the support profile 4, a seal 9 is inserted, which is then in the closed position rests on a web frame 15 of the boiler front wall 13. As can be seen from Fig. 3, the edge areas 5 'of the thermal insulation block 5 overlapped by the inner U-profile 8, so that this the thermal insulation blockS holds. Depending on the requirements of the

ίο Verschlußhalterung, sind an entsprechenden Stellen Haltebolzenöffnungen 10 in das äußere U-Profil 7 und in die Schale 2 eingeschnitten und im gleichen Sinne bei Scharnieranlenkung des Verschlusses öffnungen 12 in die Ränder 3 und in den Rand T des äußeren Profils 7, so daß dort ein Scharnierbolzen 11 eines Scharniersteges 14 eingeführt werden kann. Da dieser Verschluß nur ein geringes Gewicht hat, ist kein starkes Scharnier erforderlich.ίο lock holder, retaining bolt openings 10 are cut into the outer U-profile 7 and into the shell 2 at appropriate points and openings 12 in the edges 3 and in the edge T of the outer profile 7, so that there is a Hinge pin 11 of a hinge web 14 can be introduced. Since this fastener is lightweight, no strong hinge is required.

Die Brennerplatte 6 könnte natürlich auch als Joch 6' von außen über die Schale 2 gelegt werden, wie dies nur beispielsweise in Fig. 1 angedeutet ist. Haltebolzenöffnungen wurden in diesem Falle vorzugsweise im Bereich dieses Joches vorgesehen werden.
Eine Schau- und Explosionsklappe kann natürlich an einen derartigen Verschluß in an sich bekannter Weise ebenfalls vorgesehen werden.The burner plate 6 could of course also be placed as a yoke 6 'from the outside over the shell 2, as is only indicated in FIG. 1, for example. In this case, retaining bolt openings were preferably provided in the area of this yoke.
A viewing and explosion flap can of course also be provided on such a closure in a manner known per se.

Wie erwähnt, können mit einem solchen Verschluß eine oder mehrere öffnungen gleichzeitig abgedeckt werden.As mentioned, one or more openings can be covered at the same time with such a closure will.

This makes them relatively heavy and shows that the cross-section of the support profile (4) has a rough surface. The design is made up of two arranged side by side, depending heavily on the casting process,
