Sweden i-Sveri ge (SE) (72) Ted Conny Larsson, Gothenburg, Sweden-Sverige (SE) (7 * 0 Leitzinger Oy (5I +) Device for supporting the surface coating around tanks -Anordning för uppbäming av ytbeklädnad kring ci sterner

The invention relates to a device for supporting a surface coating around containers, comprising a plurality of supports projecting perpendicularly from the container wall and supporting a substantially horizontal rail on the outer end to which the cover guards are attached, the inner ends of the supports being supported and tightened , with superimposed holding tabs for holding each tensioning bandage.

tanks for oil and liquid fuels with an unprotected jacket have been shown to "exhale" the gases at the top of the tank from their evacuation tube. Gas exchange, which is caused e.g. the effect of the expansion and contraction of the mantle, due to its varying warming by the sun's rays during the day and cooling in the dark hours of the day, constitutes a serious environmental problem. As a result, it has been considered necessary to thermally insulate such unprotected containers.

60281 2

For example, it is known from Swedish patent publication 309 313 to place a surface coating around containers. This surface coating is intended to be placed around the shell of the tank immediately after the tank is manufactured, i.e. before it is filled with running fuel. To secure the surface coating, brackets projecting from the shell of the container are used, the inner end of which is welded to the container and the outer end of which supports a substantially horizontal rail to which the cover plates of the cover are attached.

For tanks that already contain liquid fuel, this method is not applicable because the risk of explosion when welding the tank casing is too great.

Also in cases where the container contains a liquid of such a quality that special steel must have been used in the jacket of the container, it is not suitable to perform welding work on the jacket.

In this case, it is not suitable to weld the supports to the sheath.

As a result, it has been proposed to use tension bandages placed around the shell of the container to hold the spacers to which the outer plates surrounding the insulation are attached. According to a known embodiment, tubular vertical bars are used for fastening the tensioning ties, which rest on the base of the container at their lower end and which are fastened next to the container jacket by means of tensioning ties.

The tubes support sleeves at regular intervals above each other with protrusions on top of which there is a U-shaped plate rail on which said outer plates are attached. Tighten the lashing straps before attaching the outer plates.

According to this method, the installation of the tank insulation is quite cumbersome and time consuming. Retaining the support rods in a vertical position next to the tank shell before the tensioning ties are in place and tightened causes difficulties.

Also, the tightening of the ties themselves, which can only take place after the U-shaped rails have been attached to the spacers, is difficult to perform because the space inside these rails is quite limited.

U.S. Pat. No. 3,6028,831,226,895 discloses a container in which, instead of tensioning straps, tensioning bars are used to mount vertical support rails against the wall of the container, on the rails of which the L-shaped plates can be hung to cover the container wall. , where the clamping rod runs. The installation of such an insulating layer is complicated, which of course also means that the installation costs are considerably high.

The object of the present invention is, above all, to eliminate the said difficulties and to provide a quick and simple installation of the insulation. The invention is characterized in that the tensioning bandage is attached to suspension steels, the upper end of which is attached above the container to a tension band extending around it. The suspension steels are bolted to the drawbar of the tank at regular intervals and at the same time a clamp is placed on the retaining strips. After the brackets have been fastened at regular intervals to the tightening bandage, this is tightened. Such a suspension stand can be obtained without difficulty. The actual insulating material is then placed in place and the cladding formed by the sheets covering the insulation is placed in the usual known manner.

According to a suitable embodiment of the invention, the tensioning ties spaced apart in the height direction comprise at least one tensioning screw and one helical spring, the tensioning screw being formed by a captive screw, i.e. a right-hand screw attached to one end of the tensioning bracket and a which both screws are similarly bridged by an internally threaded sleeve. This makes it possible to tighten the tightening bandage easily. It will also be possible to fasten the supports to the tank casing with the necessary tightening force, despite the changes in the circumference of the tank.

Other features of the invention will become apparent from the following with reference to the accompanying drawings, in which:

Figure 1 shows a perspective view of a part of a container with one secretion coating supported by supports supported by tensioning ties according to the invention.

Figure 2 shows a cut-away vertical section of the container jacket on a larger size.

Figure 3 shows a similar section of the sheath, its insulation and surface coating.

Figure 4 shows a side view of the top of the container.

Fig. 5 shows a larger horizontal section taken along the line V-V in Fig. 3.

Figure 6 shows a front view of a part of one of the clamping ties of the container together with several suspension steels.

In Fig. 1, reference numeral 1 denotes the cylindrical wall of the container and reference numeral 2 denotes one of several plates, suitably corrugated aluminum plates 3, 4, which form, for example, a protective sheath of an insulating layer 5 of stone wool. The plates 3, 4 of the protective sheath 2 are arranged in horizontal rows. The plates 3, 4 are fastened with pop rivets 6, 7 or the like (Fig. 5) to annular rails 8 of substantially cross-section running around the cylindrical wall 1. The rail is supported on the outer end of supports 9 arranged in horizontal rows and projecting perpendicularly from the wall 1. These supports are supported by means of a retaining plate 60281 510 arranged at their inner end, which are clamped 11, which are arranged around the container jacket 1 at intervals corresponding to the height of the plates 3, 4. The tensioning ties 11 are supported by hooks 12 of vertical suspension steels 13, the upper end of the tensioning steels being provided with a lug 14 fixed by a bolt 15 to the flange 16 of the container drawbar 17. The hooks 12 are made of suspension steel 13 .

Each tensioning band 11 is assembled from flat steels 19, 20, 21 and 22 fitted with rivets 18 or the like. A strong helical spring 23 is placed between the two flat steels 20, 21 and a shank screw 24 is arranged between the other two flat steels 21, 22, i.e. a tightening screw having a left-handed screw 25 attached to the second flat steel 21 and a right-handed screw 26 attached to the second flat steel 22 and having a correspondingly threaded sleeve 27 around the screws 25, 26.

When installing the surface coating 2, proceed as follows.

First, the suspension steels 13 are placed in place and each is fastened with a bolt 15 to the corresponding flange 16 below the tension band 17. between. The rim screw 24 is then tightened so that the support retaining plate 10 is clamped against the cylinder wall 1 under the tension of the spring 23. An insulating layer 5 is then placed in place. The rails 8 are hung in place and fastened to the outer end of the supports 9, after which the surface coating 3 is fastened to the rails.

It is clear that the tensioning ties 11 hold the supports 9 in place, although the circumference of the cylinder liner 1 is slightly reduced. Spring 23 compensates for such a decrease.

The embodiment shown and described is to be considered as an example only, and the design of the tensioning band and the suspension steels can be changed in many ways within the scope of the following claims.
