Regardless of whether the while the nut 13 to lock the Tie rods or compression rods for the application of grain nut 12 and thus the tie rod 4 is used, Men, these can also be connected to the bandages in the middle of each drum.

Bewegt sich nunmehr im Betrieb des Dampferzeu- 45 spielsweise durch Wind, so werden die aus dieser Begers auf Grund der Erwärmung des Kesselkörpers lastung resultierenden Kräfte über den üicntgeder Anschlußpunkt der Zugstangen an den Bandagen schweißten Kesselkorper 1 in die Bandagen i geleitet, um eine in Abhängigkeit von der Ausdehnung des die den Bandagen 3 benachbart sind, die in Wind-Kesselkörpers entsprechende Strecke nach außen, so richtung lieger·. Von hier aus erfolgt eine Weiterleiist dieser zurückgelegte Weg im Vergleich zur Länge 5j tung der Kräfte über den jeweils zugehörigen Ander Zugstangen sehr klein. Dadurch bewegt sich aber schlußpunkt 5 der Zugstangen 4 an den Bandagen i der Anschlußpunkt der Zugstangen an den Bandagen und über die Zugstangen 4 selbst, so daß sie zu den auf einer Geraden, da die Verschiebung des An- Hauptstützen 6 gelangen und somit vom auberen Schlußpunktes keine Längenänderung bewirkt. Somit feststehenden Gerüst aufgenommen werden.If the steam generator is now in operation due to wind, for example, the forces resulting from this load due to the heating of the boiler body are passed through the boiler body 1, welded to the bandages, via the connection point of the tie rods welded to the bandages i from the extent of the adjacent to the bandages 3, the corresponding distance in the wind boiler body to the outside, so direction lying ·. From here, the path covered is passed on. Compared to the length of the forces over the associated Ander tie rods, it is very small. As a result, however, the end point 5 of the tie rods 4 moves to the bandages i the connection point of the tie rods to the bandages and over the tie rods 4 themselves, so that they get to the main supports 6 on a straight line because the displacement of the main supports 6 and thus from the outer end point no change in length caused. Thus fixed scaffolding can be added.

Claims

Bandages for use, which are wrapped around the tightly patented claims: welded boiler body. Regardless of the arrangement of the drums, each

1. Device for horizontal support while the steam generator is in operation, starting from and management of an all-round expanding 5 the existing temperatures, a radiating body, especially for tightly welded conical expansion of the entire tightly sealed \\\: i, th selector body of steam generators, in which the boiler body, including its bandages. Around external loads (e.g. wind) to avoid tilting of the boiler body, Forces from the around the tightly welded boiler, the bandages are indirectly fixed in the outer bandages arranged in the body are guided onto the outer framework. Well-known institutions for guidance Fixed scaffolding both in the cold state and the bandages and thus the boiler body look up also in the case of the four sides of the boiler body enlarging cantilever arms due to thermal expansion Berten are transferred, with the bandages in with the bandages of the boiler body, if necessary their middle with guide parts in connection with the arrangement of a component that the Mohen, which are attached to the main supports, because of the cantilever arm, absorbs them firmly marked that the two are. On the other hand, the bandages are in hers see jev, -ils two main supports (6) of the outer center with guide parts connected to the Fixed scaffolding arranged guide main supports are attached. But it has been shown share two tie rods (4) or a compression rod that the use of cantilever arms is not only communicated are, which on the one hand in the middle of each bandage (3) 20 is associated with a high structural effort. are firmly arranged on this and on the other hand there are at least additional associations between the with the main supports (6) of the outer fixed bandages and additional supports between the yards The scaffolding can be adjusted or firmly connected by locking the main supports of the scaffolding, bind, are required, but the use

2. Device according to claim 1, characterized in that the cantilever arms are also technically not fully effective, that the tie rods (4) or sam, because deformations of individual components such. B. Pressure bars on the main supports (6) pulling the cantilever arms and the supports between the directions Lock the side with a threaded bolt (11), causing the whole boiler body to oscillate are provided, the i.i a ti the main supports (6) also does not switch off. While avoiding this; arranged housing (8) can be inserted due to disadvantages, it is already in the further development Nuts (12; 13) on the Si. nwand (10) ces known, for horizontal support and housing (8) is anchored. Guiding the boiler body directly on the bandages

3. Device according to claim 1 and 2, since the main supports of the outer fixed framework characterized in that the tie rods (4) to articulate most. But since the bandages or pressure rods in the middle (5) of each bandage 35 warm, as the outer icing, can jam (3) adjustable associated with the bandages (3) occur when the play between the bandages are. and the mainstays! is yours. However, if the play is too great, the boiler body oscillates between the Main supports so that the direct articulation of the

40 bandages on the main pillars of their task are not

is fully fair.

In a further known steam generator, it is also known to use the bandages of the boiler body

The invention relates to a device for horizontal with the interposition of oil brake cylinders zontal support and guidance of one on all sides 45 the main supports of the outer fixed framework To articulate the body, especially for the tightest.

Surrounding pipe walls, with the use of material a pendulum of the tightly welded tightly welded pipe walls to avoid a leak-proof boiler body, welded boiler body results. Are such without jamming between the bandages and Steam generator designed for high performance, so is the tightly welded boiler body and the it is necessary due to the large dimensions, external fixed scaffolding, with a single tightly welded boiler body against internal dissipation of all external forces to increase pressure, so that at least 65 destruction (e.g. wind) in the main supports is possible. but damage to the tightly welded pipe The invention is based on the object of a
