Description

The invention relates to isolation, in particular thermal insulation for pipes using Tsolier elements made from flat mats of insulating material exist. These mats are cut to the appropriate length and width to be placed on the pipelines a protective cover attached to the edges with Zimittel for joining together after the insulation has been folded down around the pipe to be insulated facing ends of the protection / cladding is provided. Insulating elements of this type can be manufactured in the factory or workshop and trimmed and stacked flat on top of each other and transported to the construction site. Only there they will placed on the pipe to be insulated and connected accordingly prepared edges closed,

In known fmseguides of such insulation, a cloth-like material, _for example woven from fibrous materials, serves as protective cladding for the insulation elements. Such a protective cover has little strength and, above all, no oäer only gait? low rigidity and is accordingly the one on the transport from the manufacturing site to the construction site and

even after it is pulled onto the pipe not grown. In addition, special locking means must be attached to the closing edges of the cladding whose handling is difficult after the insulating elements have been placed on the pipeline and to close special 'tools matched to the formation of the closure parts is required.

Recognizing the disadvantages of the previously known insulation, the invention is concerned with the task of the insulating elements to be trained in such a way that they can be handled easily and safely during transport, the work when placing the insulating elements, however, are considerably simplified, and finally the insulation from the outside is much better protected against damage.

According to the invention, this object is achieved in a surprisingly simple manner by combining several features, some of which are known per se or in a different context, in that (a) the individual insulating mats are made of mineral wool and (b) a sheet metal part serves as an outer protective covering for each mat when the insulation is finished, edge parts facing each other are bevelled, with ( _c ) a C-shaped profiled tensioning rail serving in the longitudinal direction of the Tube can be pushed over the above-mentioned folds of the cladding sheet onto the latter, and finally (d) the sheet metal part for the use of a spacer ring made of pressed insulating material is extended by the width of the spacer ring beyond the mat.

Using mineral wool as an insulating material has been around since known for a long time. In the context of the invention forming Combination, i.e. in the form of a mat together with an exterior Protective cladding made of an initially flat metal

sheet metal, still have insulating mats made of mineral wool no application found. If, on the other hand, protective cladding made of sheet metal has already been used earlier are, it did not happen in the form of originally lying flat Isolation elements, but it was first applied the pure insulating material to the pipelines, only after Once this was done, the sheet metal cladding was converted in sections after previous finishing in the workshop the insulation laid around. The preparation of the protective cover in the workshop or on the construction site consisted of that the individual .Abschnitte of the sheet metal cladding to to enable later closing, e.g. by punching holes for later screwing or riveting prepared, longitudinally beaded for adaptation to the respective ■■ to be insulating Rohrfprmen and diameter as a whole rounded and finally at one end or at both ends for the Overlap of the adjoining section were beaded, in this condition the sections became the construction site transported, spread there and pushed over the mat made of insulating material already laid on the P.ohr and closed. »

Similarly, the preparatory work in the In the workshop and during the installation on the construction site, if the sheet metal cladding was used in the form of already rounded »sections and these were pre-rounded Sections along the longitudinal edges had to be closed.

In contrast, mineral wool are used in the invention Insulation material in mat form and sheet metal as protective cladding, which are designed as flat elements, combined with one another. This results in the known properties the parts also have particular advantages by increasing the strength properties of the mineral wool and the protective cladding complement each other purposefully in an unexpected way. The sheet metal protective cladding forms a good base and support for the insulating material,

what the transport of the insulating elements to the construction site and your Handling there itself facilitated. Mineral wool on its own or in conjunction with cloth-like protective coverings does not have the necessary rigidity to achieve the during the transport with the mentioned handling for the assembly and those to be expected after completion of the insulation To withstand stresses with certainty. On the other hand, the strength of the mineral wool is quite sufficient, in order to provide good support for the protective cladding when the insulation elements are placed on the pipelines when bending, rounding and adapt to form the insulating elements, in particular because a spacer ring is made of pressed insulating material has been pushed onto the pipe and for the supporting the edge of the sheet metal part protruding over the mat works »With the invention, the assembly on the construction site for the first time easily accomplished by a single person in such a way that the finished insulation a uniform roundness as well as a uniform all round Has insulating distance. In terms of quality, the new insulation thus corresponds to that in the conventional manner with a considerably larger one Workload prepared in the workshop and on the Construction site using pre-rounded sheet metal insulation, ί

The sheet metal part 3 is provided with oppositely directed bevels 4 on the longitudinal edges. At a certain distance from the edges of its longitudinal edges, the sheet metal part is bent at 5 at an angle of 30 °. At one transverse edge, the sheet metal part can protrude so far beyond the mat that the subsequent insulation section, as shown in FIG. 3, is overlapped. The bevel 4 is not provided at this point. The sheet metal part 3 also projects on the other transverse edge for the spacer ring Q over the width of this ring over the mat 2.

On the construction site, the insulating element is installed in accordance with Invention put under Umbigen around the pipe to be insulated.

• The insulation according to the invention can not only be used Continuous insulation of pipelines find application, but also be used to the frequently existing Flange connections between sections of the pipeline to be insulated must be properly insulated. In this case it will be the sections used to isolate the flange connections: the insulation is dimensioned to correspond to the circumference and length of the flange connection.
