Abstract

Die Erfindung betrifft eine Aufhaengung fuer Fertigteilauskleidungen von schachtartigen Waermeanlagen, insbesondere von Rauchgasruecksaugungen an Dampfkesseln, wobei die Aufhaengung flexierbar und fixierbar ist. Dies wird erfindungsgemaess dadurch erreicht, dass zwischen den hakenfoermigen Elementen eine an den inneren Schachtmantel abgestuetzte Tragoese angeordnet ist. Fig. 1The invention relates to a suspension for precast linings of shaft-like heat installations, in particular of Rauchgasruecksaugungen of steam boilers, wherein the suspension is flexible and fixable. This is achieved according to the invention by arranging a tragoid supported on the inner shaft shell between the hook-shaped elements. Fig. 1

Description

Es werden Beulen und Verformungen des Schachtteiles weitgehend ohne zusätzlichen Aufwand ausgeglichen.Bumps and deformations of the shaft part are largely compensated without additional effort.

Es bestehen im Einbauzustand Bewegungsmöglichkeiten in horizontaler und vertikaler Richtung sowie bei Winkelabweichungen der Tragkonstruktion vom Sollzustand.In the installed state, there are possibilities of movement in the horizontal and vertical direction as well as in the case of angular deviations of the supporting structure from the desired state.

Die Empfindlichkeit gegen Verschiebungen durch Betriebseinflüsse,wie Schwingungen, ständiger Anprall usw. wird vermieden.The sensitivity to shifts due to operating influences, such as vibrations, constant impact, etc., is avoided.

Claims

Invention claim:

Suspension for prefabricated linings of shaft-like thermal systems, in particular of flue gas back suction on steam boilers, characterized in that between the hook-shaped elements a supported on the inner shaft shell lifting lug is arranged.

Field of application of the invention

The invention relates to a suspension for precast linings of shaft-like thermal systems, in particular of Rauchgasrücksaugungen of steam boilers.

Characteristic of the known technical solutions

For the delivery of the shaft of a thermal plant, in particular of the flue gas return duct in a steam generator, industrially prefabricated blocks, ring segments or rings are used to an ever greater extent. They are the old conventional refractory masonry with chamotte, gas concrete, kieselguhr u. a. Replace masonry, as these technologies are extremely labor-intensive and labor-intensive. Known is a lining of temperature and wear-stressed shaft-like system components for thermal systems, wherein between the ribs of the wear concrete part and the panel, a mechanically fixed frame is arranged, the hook-shaped brackets

and is attached via thermo-elastic bushings on the wear concrete part (DD-PS, WP F 23 J / 2738266).

The disadvantages of this solution are that in dimensional deviations of the steel construction shaft parts, which arise during operation due to operation and wear, only a relatively small range of these deviations can be constructively compensated. In case of deformation of the shaft parts, proper connection conditions can only be established through an additional repair effort. Movement possibilities exist only in the horizontal direction.

Object of the invention

The aim of the invention is to develop a suspension for prefabricated linings of shaft-like heat systems, in particular of Rauchgasrücksaugungen of steam boilers, which allows to carry out a simple and effective assembly and disassembly of the finished parts, even with heavily discarded manhole covers.

Explanation of the essence of the invention

The invention has for its object to produce a suspension for precast linings of shaft-like heat systems, in particular of Rauchgasrücksaugungen of steam boilers, which is flexible and fixable. This is achieved in that according to the invention between the hook-shaped elements a supported on the inner shaft shell lifting lug is arranged.

embodiment

In one embodiment, the invention is explained in detail.
The drawings show:

Fig. 1: Suspension with strong deviations of the steel sheet jacket from the vertical Fig. 2: suspension with supported lifting lug
Fig.3: Suspension without supported lifting eye

The suspension consists a js the hook-shaped elements 4 and 5, which are fixed to the sheet steel jacket 1 and the finished part 6 and connected via the lifting lug 3 with 2 support. The hook-shaped elements 4 are welded to the sheet steel jacket 1, which can be compensated by the structural design of the suspension operational deformations of the steel sheet jacket 1 to a large extent and are of minor importance. The lifting lug 3 is hooked into the hook-shaped elements 4.

The compensation takes place via the welded to the lifting lugs 3 supports 2, which are adapted in size to the respective state of the steel sheet jacket 1 (Fig. 1).

In completely vertical sheet steel jacket 1, the support 2 unfold, which is hardly possible after prolonged operation of the flue gas back suction (Fig. 3).

The hook-shaped elements 5 are welded to the non-illustrated frame of the finished parts 6 and are suspended in the lifting lug 3. This creates a double articulated suspension that is very adaptable. Advantages of the invention:

- It is bridged a multiple-sized range of dimensional deviations of the steel sheet jacket without additional effort.
