Dismountable storage tank for mineral oils

It is known a collapsible large storage container, which inabes special for the military short-term storage of fuels is brought to screw together from floor and wall segments. Containers of this type have a content of several hundred cubic meters. The segments are flanged through a plurality of through holes seated screws are tightly connected. Because of this large number of visual ceilings, the spacing of which is the usual for flange connections The assembly is tedious, though the purpose of this field container after the shortest possible construction time demands.

The aim of the invention is to provide a collapsible large-scale container to create whose assembly time is only a fraction of that the known container is.

According to the invention are tightly screwed together on one of segments Bottom ring screwed on with the interposition of a plastic tarpaulin wall segments forming the container bottom, which carry a roof structure. The wall segments, which are preferably manufactured using the extrusion process, are bordered in profile by essentially square strips, are fastened to each other and to the base ring segments with the interposition of seals by means of clamp screws.

In the case of the "containers according to the invention", the Container bottom previously formed from sheet metal segments on a quickly mountable bottom ring and a tarpaulin, and the torsionally rigid Bars, with which the sheets of the wall segments are bordered, allow the use of relatively thinner ones Sheets and allow a spacing of the clamp screws that is many times larger than that of face screws. It will therefore much fewer screws are required, moreover leave it It is easier to attach clamp screws than screws of flange connections.

α For the purpose of easy and safe application β of the clamp screws the invention provides the strips outside with a to provide a continuous nose.

The vertical strips of the wall segments are appropriately preserved a Nufc / Feather profile, where the depth of the feather is equal to the thickness an inserted seal is smaller than the depth of the groove.

The lower bar of the wall segments appropriately receives an im essentially flat surface, delimited by a centering collar, which the plastic tarpaulin presses into place »For the upper bar of the Wall segments a bead profile is provided over the one Roof tarpaulin is pulled.

In the drawing, the invention is explained using an exemplary embodiment W.

Pig. 4 a corner joint according to point IV of FIG. 1, Pig. 5 shows the upper edge of the wall segments in cross section corresponding to point V of FIG. 1.

A bottom ring 1 screwed together tightly from segments takes a number of wall segments 2, the height of which corresponds to the shell height of the container and its width corresponds to the loading width for road transport. The wall segments are mutually and with the floor ring segments by means of clamp screws 3 firmly clamped. The bottom of the container is a plastic tarpaulin 4. The roof structure consists of loosely laid out Lightweight trusses 5 t purlins 6 and one overplaced plastic plane 7 as a roof skin. The tarpaulin 7 is lashed to cams 8 of the wall segments »

The construction of the open container is carried out on a solidified bed of sand 9 after previous design of the bottom ring 1 and after embedding the plastic tarpaulin 4 is laid out by support plates 10. and then erected a tripod support 11 for the top point of the roof structure. The Set up wall segments 2 and each with a tie 5 to assure.

With the vertical joint of the wall segments 2 take hold accordingly Pig. 2 two strips 12 and 13 with groove 14 and peder 15 in one another. The form closure caused by this takes the transverse forces of the wall segments. The tongue 15 is shorter than the groove by the thickness of a completely embedded plastic seal 16. On the outside, the strips 12 and 13 are provided with lugs 17 which be engaged from behind by the clamp screws 3.

Because the strips are torsionally stiff due to their essentially square profiles and stiffened in the direction of the wall by the metal sheets are, the distance between the screws 3 can safely be 30 cm or more. With regard to the hydraulic The load on the impacts in the lower area is as shown in Fig. 1 intended to keep the screw pitch tighter at the bottom than at the top

meeeen. If the strips are produced in an extrusion process, so βμβΓβΙοΙιβηα tight tolerances, especially the tongue and groove connection.

When the wall segments meet the floor ring horizontally, the sealing surface is flat as shown in FIG. 3 because of the plastic tarpaulin 4. A lower seal 18 lies firmly in a groove in the bottom ring profile. An upper seal 19 is placed loosely. The bottom ring profile is provided with a centering collar 20, to a centering shoulder 21 engages the ledge 22 - "Also, this bar 22 has a nearly quadratischeβ profile on 'and the nose 17 for the clamp screw. 3

The vertical joints according to FIG. 2 and the horizontal joints according to FIG. 3 form corner joints according to FIG. 4 are offset from the joints 23 of the floor ring segments arranged. The joints 23 of the floor ring segments are interposed tensioned by sealing material through tabs 25 »26 and 27 ·

The wall segments are used for the loose support of the roof structure Provided at the top with bead-shaped strips 24, so that the plastic tarpaulin 7 is braced over it without damage can. The roof trusses 5 do not reach over the strips 24 and are on brackets (not shown) on the inside of the wall segments.
