Description

The invention relates to a method for the production of large containers e.g. Silos, mixing containers, storage containers, tanks and the like. From prefabricated individual segments as well as such an individual segment and an alignment tool for aligning adjacent individual segments during their assembly or assembly.

Open-plan containers have been used increasingly for many years, for example to have cement available at a construction site, to store raw materials or intermediate products for the production of plastics or to hold liquids in large quantities. Such large-capacity containers have considerable dimensions, for example between 10 and 40 m in height and a few meters in diameter. There is the problem of transporting such large, wide containers from the production site to the place of use in a quick and cost-saving manner.

One way of solving this problem is that, according to DE-OS 21 59 602, the large-capacity containers are designed with slightly conical main parts which can be nested inside one another during transport, so that a large number of such stacked main container parts without excessive transport Space can be transported.

Another way of solving this problem is that individual segments for the large-capacity container are prefabricated in the production facility and transported to the place of use and are only assembled there to the finished large-capacity container. It is known (US Pat. No. 3,292,324), containers with a square cross section thereby assemble at the place of use that longitudinal angle irons are arranged inside the container, to which flat plates are screwed, while the edges of these plates extending transversely to the container axis are provided with angle irons or are even angled outwards so that several such individual segments can be attached to one another. According to this principle, it is also known (US-PS 4 040 218, FR-PS 1 000 784 and IT-PS 555 940) to assemble approximately cylindrical silos in cross section in that annular cylinder parts are joined to one another with the insertion of end flanges and screwed together . It is also known to divide such ring-shaped container parts into individual ring segments and to overlap them by joining or assemble them to form the ring parts. Such individual segments have a wall part which corresponds to a wall region of the container, and at least one support part which projects from the edge of this wall part and which not only stiffens the wall part but is also used for connecting adjacent individual segments by means of a connecting means, for example by means of screws.

However, it has been shown that the assembly of such individual segments on the construction site leads to major problems, since the individual segments themselves are relatively heavy. However, aligning the individual segments to one another presents even greater difficulties if a few individual segments have already been put together but are then to be connected to a number of other individual segments. Since the individual segments are prefabricated, it is important that when they are assembled they also come into the intended position aligned with respect to one another or with respect to one another before the connection thereof takes place, especially since the sealing of the large-volume container to the outside also largely depends on this orientation.

The invention is therefore based on the task of mounting of the individual segments to simplify the large-capacity container or at least parts thereof, thereby reducing assembly time and assembly costs.

The invention consists in that the individual segments are joined to one another with support parts which have at least one recess which is accessible from the outside, in particular on that side of the support parts which faces away from the adjacent individual segment to which it is to be connected. Subsequently, an alignment tool with a holding member is inserted into the cutout of the one individual segment, in particular hooked and latched, and applied to the adjacent attached individual segment with an abutment member. Finally, the alignment tool is pivoted up to the alignment of the joined individual segments while sliding along or rolling or rolling on a surface of the adjacent individual segment, aligning it with respect to the other individual segment.

To carry out this method, the use of an alignment tool according to a further embodiment of the invention is recommended, which has a holding member for insertion into a recess of a support part of one individual segment and an abutment member for contacting the surface of an adjacent individual segment in such an arrangement that at least that Investment member is pivotable with respect to the recess, thereby moving one individual segment in relation to the other, especially using leverage in the aligned position.

It is advisable if, according to a further embodiment of the invention, the individual segment has at least one support part located at the edge which has a recess which is accessible from the side which faces away from the edge and extends in particular along the entire edge of the support part. It is recommended if an extruded part is used as the support Profile bar is used, which is welded to the wall part consisting in particular of thin-walled sheet metal.

If the invention is used in substantially cylindrical or slightly conical large-capacity containers, without being limited thereto, since rectangular-shaped large-capacity containers can also be produced according to the invention, it is advisable if the extruded support part designed as a profile rod is bent and then welded to the sheet metal is, so that the prefabricated individual segments are parts of a ring or ring segment, which have the support parts on the end faces of the ring. In addition, it is advisable to provide the other edges, which run between the end faces of these ring segments, with such support parts in order to also align and connect the individual segments of a ring in a corresponding manner to one another. The connection can be made by screwing, welding and / or by means of clamping devices.

• FIG. 8 is a partial view corresponding approximately to FIG. 3 according to another embodiment of the invention;

According to FIG. 1, the silo 1 serving as a container is composed of a number of individual segments 2, which form tiered rings, each ring according to FIG. 2 being assembled from four individual segments 2. On the cylindrical main part of the silo 1, which consists of five such ring levels, a cover is placed, which is provided with a filling opening 3 and a further filling and / or venting tube 4, through which the contents can be filled. The main silo part is placed on a support ring 5 composed of a U-profile, which is supported on support feet 6. In addition, the main silo part is welded to a downwardly tapering discharge funnel 7.

The individual segments 2 consist of a wall part 8, for example relatively thin-walled aluminum sheet, and support parts 9, which are designed in the form of flanges projecting outwards and have openings 10 through which screws can be inserted as connecting means 12, around the individual segments 2 after their alignment to be able to connect with each other in relation to each other.

1 and 2, the wall parts 8 of the individual segments 2 have rectilinear support parts 9 running in the longitudinal direction LR of the silo 1 as well as support parts 9 directed transversely thereto and following the cylindrical periphery of the silo 1.

This can be seen more clearly from FIG. 3: In this exemplary embodiment, two individual segments, namely the upper individual segment 2a and the lower individual segment 2b are already connected to one another in the aligned position. The wall part 8a of the upper individual segment 2a is welded to the annular support part 9a along the weld 11a and the support part 9b of the lower individual segment 2b, which also protrudes radially outwards, to its wall part 8b along the annular weld bead 11b. Correspondingly, the support parts 9aʹ and 9bʹ running in the longitudinal direction LR are welded along the wall parts 8a, 8b to the outside thereof. A connecting pin 12 is inserted through the openings 10 in the support parts 9a, 9b. After tightening the nut 13, the two individual segments 2a and 2b are screwed together one above the other. The recesses 14a and 14b serve, as will be described in the following, for aligning the two individual segments 2a, 2b with respect to one another. After the connection, it is possible to weld the two wall parts 8a, 8b in the aligned position at their abutment, for which purpose a welding bead 15 can be drawn on the inside.

According to FIGS. 4 and 5, the alignment tool 16 shown schematically there has a carrier 17 which is firmly connected to a handle 18 by welding. At the end of the arm 17a of the carrier 17 there is a bearing 19 for the storage of 2 rollers which serve as contact members 20. The holding member 21 is designed in the form of a hook which can be pivoted in relation to the carrier 17 about the axis 22 in the direction of the arrow. It is advisable to choose the angle α between the angled hook part 23 and the arm 24 extending to the pivot bearing 22 between approximately 60 and 80 °. The diameter of the shafts 25 of the bearing 19 is 16 mm in this example, while the outside diameter of the contact element 20 designed as a roller or rolling element is approximately between 30 and 50 mm wearing.

FIG. 6 schematically shows the position of the two adjacent individual segments 2a and 2b, which has been placed on top of one another but is not yet aligned with respect to one another. It is a question of pushing or pulling the upper individual segment 2a forward in the direction of arrow V so that the two openings 10a and 10b are aligned with one another. For this purpose, the angled hook part of the holding member 23 is inserted into the downwardly open recess 14b. Since the recess 14b is also inclined at an angle β shown in FIG. 7 between approximately 60 and 80 ° with respect to the longitudinal direction or vertical in this example, it is ensured that the holding member 23 when the contact member 20 is placed on the outer surface 30 of the wall part 8a of the upper individual segment 2a and when it is rolled down in the direction of the arrow U does not slip out of the recess 14b. Instead, the holding member 23 remains with the arm 24 extending to the pivot bearing 22 in the position shown in FIG. 6, while by pulling up or pivoting the handle 18 in the direction of arrow H, the angle γ between the arm 24 of the holding member 23 and the carrier 17 reduced. This reduction in angle causes the roller-shaped contact element 20 to move downward along the outer surface 30 of the upper individual segment 2a by rolling in the direction of the arrow U, while at the same time this upper individual segment 2a is pushed forward in the direction of the arrow V until the two openings 10a and 10b in accordance with FIG. 7 are aligned. In this aligned position, the connecting means 12 can be inserted through the openings 10a and 10b and the two individual segments 2a and 2b can be connected to one another and, if desired, also welded to one another at the connection or joint, whereupon the alignment tool 16 is removed. It is important that the alignment member 23 does not slip out of the recess 14b of the support part 9b during alignment. It is therefore important that this recess 14b be in this position opens downwards, ie opposite to the end edge 26 of the lower individual segment 2b, ie in a direction facing away from the adjacent individual segment 2a.

Another alternative in the already connected state of the two individual segments 2a and 2b is shown in FIG. The support parts 9a, 9b, which protrude flange-like at an angle of 90 ° to the longitudinal extension of the wall parts 8a, 8b, are also arranged with the cutouts 14a and 14b on sides facing away from one another. Instead of connecting bolts 12, the two support parts 9a and 9b are held together by a clamping ring 27. If necessary, the tension ring 27 can also be removed after the weld seam 15 has been applied and an additional weld seam 28 can also be provided on the outside at the joint of the two outer edges 26 of the two individual segments 2a and 2b.

While the wall parts 8a consist in particular of aluminum sheet, extruded aluminum profile material is used for the support parts 9a, 9b, the wall thickness of which is considerably thicker than the wall thickness of the wall parts 8a, 8b.

Instead of the outer weld seam 28, a sealing ring can also be arranged between the clamping ring 27 and the two support parts 9a, 9b.

The use of extruded profile material for the curved support parts 9 with trough-shaped recess 14 extending in accordance with their length has the additional advantage that the alignment tool 16 can be displaced along this trough-shaped recess 14 in order to gradually align the individual element 2 with respect to the adjacent individual segment 2 to initiate. Of course, several alignment tools can also be hooked into one and the same trough-shaped recess 14, so that in particular for larger and heavier ones Ren individual segments or container parts already assembled from individual segments, several operators actuate such alignment tools, in particular at the same time, and arrange the alignment. It goes without saying that mechanical operation of alignment tools is also possible instead of manual operation.

The wall parts 8 not only form the essentially cylindrical container shell or main part, but can also be designed with the support parts 9 to assemble the outlet funnel 7 and the container roof 100 as individual segments 2 with a correspondingly modified shape.

However, the invention is in no way limited to terrestrial applications, but can also be used, for example, for the assembly of container or support parts under water, for example components of drilling rigs, or in exterrestrial space, for example for mounting space stations.
