Description:
Mounting stand for pipelines and other objects

The invention relates to a mounting stand according to the preamble of claim 1.

Typical applications of the invention are so-called trace heating installation works, in which onto the outer surface of a pipe to be heated are mounted heating cables and which pipelines are thermally insulated after mounting of the cables. However, the invention can be adapted also to many other installation objects, which can be thermally insulated or uninsulated.

The invention is characterized by that, which is in more detail defined in the characterizing part of independent claim 1. The dependent claims define

embodiments of this invention and details supplementing the independent claim.

The electric heating of piping, which is also called trace heating in professional jargon, is generally used to prevent freezing in piping located in outdoor spaces and exposed to cold weather conditions, and also in process piping, in which it is desired to maintain the temperature of a fluid to be transported at a level required by the process or by the viscosity characteristics of the fluid. Trace heating can also be used to raise the temperature of a fluid to be transported. In typical solutions, heating cables are mounted tightly onto the outer surface of the piping to be heated by specialty tape fastenings, and the piping is insulated in order to minimize heat loss and to protect the cables. The heating cables are coupled into the electricity network in a coupling box to be fastened in connection with the pipeline. The heating cables should in their entirety be located within an insulated space.

Regarding the characteristics of the cables, installation work and standards as well as safety directives, there is an abundance of instructions available from cable manufacturers and system vendors, but the availability of functional fastening and installation supplies needed in practical installation work is inadequate. Due to this inadequacy, for example, for fastening coupling boxes onto a pipeline and running heating cables from a coupling box in connection with a pipe, it is generally necessary to have an electrician to design and create a technical solution at every single site. A common problem is also the difficulty of thermal insulation work regarding running the heating cables to the pipe, due to case-by-case mounting stand solutions.

The object of the novel invention currently presented is the rationalization and decreasing in expense of the installation work described above, as well as the elimination of installation mistakes, especially with regard to fastening and mounting the coupling boxes of heating cables to a pipe, as well as to running heating cables to a pipe. By using the new type of mounting stand according to the invention, which is factory-made and suitable for a wide pipe diameter, there is assured a sturdy fastening of the coupling box to the pipeline, the straight line of the cables or elements to be mounted and the support by the bend in the sheet element at the lead-out holes of the coupling box, and the smooth operation of installation and insulation work is improved. In the following, the invention is described in more detail with reference to the accompanying drawings, in which:

Fig. 1 shows a mounting stand according to the invention mounted onto a pipeline without thermal insulation

Fig. 2 shows the section A - A of the mounting stand from Fig. 1 Fig. 3 shows the section B - B from Fig. 1, the pipeline being thermal

insulated

Fig. 4 shows the sheet element as a separate component Fig. 5 shows the support leg as a separate component Fig. 6 shows the protective cover and the insulation component fastened thereto

Fig. 7 shows, as an enlargement of site C of Fig. 3, a detail at the connection point of the sheet element, the support leg and the protective cover. Fig. 1 shows the mounting stand 1 fastened to a pipe 10 by clamp bands 7, as viewed from the side of the protective cover 4. On the upper side of the protective cover 4, fastened to the upper part 29 of the sheet element 2, is a coupling box 11 for the electric couplings. Instead of the coupling box 11, to the upper part 29 can also be fastened some other element, the electrical wires leaving from which are led inside the protective cover 4 to the installation object.

Fig. 2 shows the section A - A of Fig. 1, which shows the casing structure formed by the protective cover 4 and the sheet element 2 and through which the heating cables and any other electrical wires, such as, for example, thermostatic cabling, are run from the coupling box 11 in connection with the pipe 10. Also seen in the figure is the support leg 3, over which the clamp bands 7 are mounted. Fig. 3 shows the section B - B of Fig. 1. The sheet element 2 can preferably be implemented as shaped from its upper end such that the directional displacement of the upper sheet part 29 of the sheet element 2 in relation to the lower sheet part 30, implemented using the bends 22, enables mounting of the heating cables as straight wires from the coupling box 11 to the pipe 10, inside the casing structure formed by the protective cover 4 and the sheet element 2. Fig. 3 shows one wire schematically as a dashed line 28. In regard to the edge shapes directed towards the sheet element 2, the protective cover 4 is implemented to correspond to the design of the sheet element 2. In the embodiment of the figure, the locking of the protective cover 4 to the sheet element 2 is implemented by the connection of the projections 15 in the lower end and upper end of the protective cover 4 to the apertures 16 of the sheet element 2, as well as by securing elements 8, which are mounted through the apertures 25, shown in Fig. 6, in the projections 15 of the upper end of the protective cover 4. The thermal insulation is presented in principle in the figure.

Fig. 4 shows the sheet element 2 as a separate component. In the installation stage, the leg part 5 of the sheet element 2 is the part receiving support from the pipe 10 or other structure. Into the leg part 5 are machined through-holes 13 for the clamp bands 7 and the spurs 19 of the support leg 3, shown in Fig. 5. The sheet element 2 further has apertures 16 for locking the cover as well as apertures 17 of the leg part 5 for the gripping projections 23 of the support leg 3 spurs 19. The sheet element 2 can also be equipped with apertures 24 in order to facilitate the running of cables from the leg part 5 as well as the fastening of cables to the sheet element 2, as well as with other possible perforations, such as with coupling box fastening holes. The fastening holes 24 of the lower sheet part 30 can be used, for example, for fastening wires with cable ties, the cable ties running around the fastening shafts 24a arranged into the holes 24. The parts 18 of the leg part 5 of the sheet element 2 receiving support from the pipe 10 surface are preferably shaped as narrow edges of the sheet in order to minimize heat conduction between the pipe 10 and the mounting stand 1. The leg part 5 further has fastening holes 27, which allow the fastening of the sheet element 2 directly onto, for example, a fastening bracket arranged to the surface of a pipe or other structure, or to some other fastening support, for example by screws, wherein neither the support leg 3 nor the clamp bands 7 are necessarily required.

Fig. 5 shows the support leg 3 as a separate component. The end parts of the spurs 19 of the support leg 3 are shaped such that they have bent projections 23, which, in the installation stage, are inserted into the apertures 17 of the leg part 5 of the sheet element 2.

Fig. 6 shows one embodiment of the protective cover 4 as a separate component.

In the lower end and the upper end of the protective cover 4 are projections 15, which, in the installation stage of the protective cover 4, are inserted into the apertures 16 in the sheet element 2. The fastening of the protective cover 4 to the sheet element 2 is secured by securing elements 8 inserted through the apertures 25 located in the projections 15 in the upper end of the protective cover 4. As securing elements 8 can be used, for example, cable ties, which are generally used in electrical installation work. Once it is mounted into place and secured, the protective cover 4 rigidities the mounting stand 1 into a sturdy structure. The protective cover 4 can be equipped on its inner surface, for example, with a thermal insulation element 26 fastened by gluing in order to facilitate insulation work. Fig. 7 shows a detail of the connection point of the mounting stand 1 and the pipe 10, as viewed from the direction of the pipe 10. The sheet element 2 and the support leg 3 are fastened by clamp bands 7 to the outer surface of the pipe 10.

The projections 15 in the lower part of the protective cover 4 are inserted into the apertures 16, shown in Fig. 4, in the leg part 5 of the sheet element 2.

Presented above is the basic solution of the invention and some preferred structural embodiments. Flowever, the invention is not limited to only the embodiments presented herein, rather the basic idea of the invention can be implemented in various embodiments within the scope of the inventive basic solution defined by the independent claim. A mounting stand according to the invention is suitable for mounting i.a. onto pipes with the outer diameters of over 30 mm. The components of the mounting stand are preferably manufactured from sheet metal as sheet parts that are laser-cut and bent into shape. The mounting stand can also be used in connection with other objects than pipes, for example, in electrical cabinets, various beam structures etc. The sheet element 2 can be fastened through the fastening holes 27 to a desired structure, if necessary, without clamp bands and the support leg, for example, using sheet screws or other suitable fastening means. Further, the mounting stand can be used, for example, for mounting thermostat capillary tubes. These kinds of capillary tubes are sensitive to impacts and bending, and a sheet element 2 according to the invention enables their installation as straight tubes from the coupling box to the usage site. At the same time, they can, due to the bends 22 of the sheet element 2, receive support from the lower sheet part 30 of the sheet element 2.
