Definitions
- the invention addresses a multi-shell formed piece, in particular a pipe for restoring chimneys, comprising at least two concentric tubes with spaced-apart walls and insulating material being disposed therebetween, the insulating material consisting of at least one bent insulating plate.
- Multi-shell formed pieces of the kind in question have been known for years in the most various embodiments. Most of them are formed pieces for chimneys. An example is given in German applications DE-OS 19 22 581 and DE-OS 31 39 338.
- the insulating part of the formed piece known from DE-OS 19 22 581 consists of three shell segments forming a pipe-like shell in circumferential direction. Said segments are made of mineral wool and loosely inserted in the circular gap between the walls of the formed piece, with the interior walls or interior pipe being inserted after the pre-assembly of the insulating material.
- the shell segments used for insulating are expensive to manufacture and relatively large in size which in turn increases packaging, transportation and storage costs.
- shell segments of this kind often have a thickness tolerance of several millimeteres and, therefore, usually require grinding of the surfaces to a given desired thickness to allow insertion of the segements between the walls of the formed pieces. This procedure further increases manufacturing and assembling costs.
- the formed piece known from DE-OS 31 39 338 is also used to build chimneys, with the gap between the walls of the formed piece being filled with webs of mineral wool.
- the webs are first loosely fitted to the inner side of the external jacket of the formed piece. At their inner sides, the webs are then covered with thin sheet metal plates, said plates having portions which project over the edges of the formed piece and are bent toward the outsides.
- the sheet metal plates form a type of gap whose opening is slightly larger than the cross section of the inner wall or pipe to be inserted. The so formed sheet metal gap then receives the inner pipe resulting in the compression of the insulating layer. Once the insulting material is inserted, the sheet metal plates are removed so that the insulating material comes in close contact with the walls of the circular gap which it fills.
- the DE-OS 37 05 725 describes a multi-shell formed piece comprising an inner tubular member, a supporting outer coat member and an insulating layer being disposed between the tubular member and the coat member and surrounding the tubular member.
- the insulating layer is formed by a flexible plate of insulating material which is folded or pleated radially in the gap between the tubular member and the coat member.
- Object of the invention is to further develop and configure a formed piece such that it exhibits good insulation qualities while manufacture and design remain simple.
- the multi-shell formed piece accomplishes the aforementioned object with the features of claim 1.
- the multi-shell formed piece is characterized in that the fibers of the insulating material run approximately parallel to the surface of the insulating plate, such that they are also essentially parallel to the surfaces of the walls and, hence, transverse to the heat current.
- the invention combines the spatial advantages of insulating plates, i.e. transportation, with the thermal advantages of insulating shells or pipes in that the originally flat plates are bent to assume the shape of a pipe and disposed between the walls of the formed piece to act as insulating material.
- the properties of the insulating plates must be such that they do not break during the bending procedure. This is achieved by selecting an appropriate initial density and laminating a fleece to one side of the plate. Since the insulating plate is bent, the fibers run almost parallel to the surfaces of the walls to be insulated and, hence, transverse to the direction of the heat current. This fact account for an optimal heat conduction resistance once the unit is fully assembled. Insulating plates with largely constant cross sections additionally account for an optimal heat current.
- Such formed pieces are particularly suitable for restoring already existing chimneys, a fact for which there is an increasing demand on the market as more and more boilers with an energy-saving heat output or so called low-temperature boilers are offered.
- the exhaust gas temperature is below the dew point allowing condensing water to precipitate at the interior walls of chimneys with poor thermal insulation. The wall thus become moist and flue gas exhaustion is impaired.
- the insulating material be configured at least in circumferential direction as one single piece, i.e. one single insulating plate is used in circumferential direction.
- the dimensions of this insulating plate would have to be such that the edges which run coaxially to the formed piece contact each other to thus form an insulating pipe.
- the contacting edges can be advantageously bevelled such that the portions of insulating material slightly overlap in the contact zone.
- the insulating plate may have a trapezoidal cross section. Dimensional tolerances at the edges do, hence, not have any negative effect as the wedge-like edges sufficiently overlap.
- the insulating plate it is also conceivable to configure the insulating plate as a pipe-like segment having a longitudinal slot. Said slot preferably runs tangentially to the inner wall of the pipe-like segment in order to advantageously account for tolerance differences even in pipe-like segments.
- the thickness of the insulating material or the insulating plate could allow for a some play between the walls of the formed piece and the insulating material.
- the walls can be provided with bars or spacers extending therebetween and preferably at the ends thereof. These spacers or bars thus firmly connect the walls to one another ensuring that a fixed distance is maintained throughout. Further, the walls cannot assume their coaxial position until the insulating material is inserted such that the insulating material itself acts as a spacer providing a largely constant distance between the walls. However, the latter possibility involves a higher degree of manufacturing complexity as the walls or pipes must be held in a coaxial arrangement during assembly.
- Fig. 1 shows a dual-shell formed piece, or more strictly speaking a dual-shell pipe 1 in accordance with the invention.
- Said pipe 1 has two coaxially disposed, spaced-apart walls 2, 3 and a piece of insulating material 4 provided between said walls 2, 3.
- the insulating material 4 may consist of insulating plates 5 with a largely constant cross section.
- the insulating plates 5 are made of rock wool.
- FIG. 2 The diagrammatic representation of Fig. 2 indicates that the fibers 6 of the rock wool have a particular direction, i.e. they are uniformly oriented in one direction.
- the fibers 6 run approximately parallel to the surface of the insulating plate, thus also running approximately parallel to the surfaces of the walls 2, 3 and, hence, transversely to the direction of the heat current indicated by arrows 7 in Fig. 2.
- the insulating material is configured as one single piece running circumferential direction, i.e. one single insulating plate 5 in circumferential direction.
- Fig. 2 indicates that the axially disposed edges 8 of the insulating plate 5 contact each other. The edges 8 are bevelled to form an acute angle which ensures a slight overlapping of the insulating material 4 in the area of the contacting edges 8 so as to account for dimensional tolerances.
- Fig. 2 is at the same time a cross section of the pipe-like segment having a slot running almost tangentially to its inner wall.
- Fig. 3 clearly shows that the insulating plate 5, when unrolled, has a trapezoidal cross section in longitudial direction.
- Fig. 1 also shows that at their lower ends the walls 2, 3 are held by bars 9. Said bars 9 extend between the two walls thus connecting them so as to be spaced apart from each other at a foxed distance. Once the insulating material 4 is inserted the walls 2, 3 are further fixed in their positions by said insulating material 4. Thus, even the ends of the walls 2, 3 which do not have a cross-linking bar, i.e. the relative positions of the walls 2, 3, are quasi fixed.
- Fig. 4 shows an embodiment of a device for disposing the flexible insulating plate 5 between the coaxially disposed, spaced-apart walls 2, 3 of a dual-shell formed piece, i.e. the above discussed dual-shell pipe 1.
- Fig. 4 also shows that the internal tool 10 is provided with a circumferential, external enlargement 12 which, on the one hand, serves as an abutment and, on the other hand, as a transition to the inner wall 2.
- the external enlargement 12 projects from the internal tool 10 by the thickness of the inner wall 2 and forms a transition from the internal tool 10 to the inner wall 2.
- Fig. 4 shows that the internal tool 10 projects form the area of the external tool 11 in a direction facing away from the formed piece or pipe 1.
- the internal tool 10 has a smooth external surface 13 to ensure smooth insertion.
- Fig. 4 also shows that the external tool 11 has an approximately funnel-like configuration.
- the external tool 11 has an area 14 which expands toward the free end. Said area 14 together with its wall forms a stop for the external tool 11. It is understood that the inner surface 15 of the expanding area 14 of the external tool 11 is also smooth to support the smooth insertion of the insulating plate 5.
- Fig. 4 may also serve to illustrate a process for disposing flexible insulating plates 5 between the walls 2, 3 of dual-shell pipes 1 using the above discussed device of the invention.
- the internal tool and the external tool 11 are detachably placed onto pipe 1 or between the walls 2, 3 of pipe 1.
- the internal tool 10 serves as an abutment and to bend the insultaing plates 5 while the external tool 11 acts as a guide.
- the internal tool 10 and the external tool 12 serve as guides for the insulating plate 5, and, if ncessary, to compress the latter.
- the insulating plate 5 is bent around the internal tool 10. Subsequently, the so bent insulating plate is inserted into the gap between the walls 2, 3. If necessary, the insulating plate 5 is compressed during its insertion. Once the insulating plate 5 is in its final position, i.e. completeley inserted, the internal tool 10 and the external tool 11 are removed again.
- Figs. 1 and 4 indicate that it is possible to successively insert as many insulating plates 5 as necessary into the gap between the walls 2, 3 until the gap is filled over the entire length of the formed piece. During their insertion into the gap between the walls 2, 3 in longitudinal direction, the insulating plates 5 were subject to compression which further improves thermal insulation.
