Abstract

In a large package of insulation material products, in particular mineral wool products in the form of panels or rolls or the like, which consist of at least two stacks of rock wool products and wherein each stack is wrapped with a sheeting, which surrounds the stack in the form of an envelope, two adjacently lying principal surfaces of the stack are joined to one another by means of a superposed sheeting, in which eye-like handle loops are formed, at least one handle loop being arranged on each stack.

Description

The invention relates to a large container according to the preamble of patent claim 1 or 2.

Insulation products used in the construction industry, in particular mineral wool products in the form of plates or rolls, are usually kept in the form of bundles from a stack of individual plates or plate packs arranged one above the other or individual rolls or modules from several rolls for the purpose of transport and storage. These insulation products are products in the density range from 13 kg / m ³ to 200 kg / m ³ . Since large areas of the building fabric usually have to be insulated, a relatively large amount of insulation material is required for insulation purposes, so that the transport to the customer and to the construction site of these voluminous mineral wool products, which are used in large quantities, causes problems. For this reason, more and more people have started to pack these mineral wool products in large containers and to provide them with a wooden pallet. Large containers of this type are then transported on the bottom side with the aid of a forklift which engages in the pallet or on site by means of a crane to the place of use, e.g. B. roof brought. On the construction site in particular, however, the wooden pallets that are freed up are increasingly causing problems with regard to their disposal. On the one hand, they have to be removed from the building, e.g. B. roof, transported back to the building site and then disposed of again by this.

It is therefore already known for the purpose of transporting such containers or stacks (EP 544 704 B) a film that envelops the stack at one end in two layers a tab aligned in the middle of the stack, welded together and in the welded tab provide handle openings next to each other. With this solution a pallet has already been dispensed with as a means of transport, since one Transport device can serve the handle openings.

For large containers, which consist of several stacks arranged side by side, e.g. B. from fertilizer bags it is already known (WO 98/26977), instead of pallet lifting eyes to be used, which are formed from the same material as the shell of the multiple stacks. For this purpose, a fabric web around z. B. wrapped two stacks and in the area of the interface between the two stacks arranged side by side upwards over the upper one Main surface of the shell pulled and through a slit-like opening introduced into the shell voltage, which creates an eyelet-like grip loop for the engagement of a means of transport results. Apart from the fact that only an eyelet-like grip loop is available is given when handling the large container by the means of transport in particular problems arising from the fact that the handle strap by additional auxiliary personnel held up and kept apart accordingly to make an intervention through the means of transport.

Furthermore, it is known to have large containers for transport with several loop-like handles to be provided knotted from wrapping tapes or wrapping cords are, however, which is disadvantageous in the case of mineral wool products, because such tapes cut in and therefore mostly with an additional sheet of film underneath must be used, which increases the packaging effort. It also results with these tapes or cords in the area of the handle loops the same problem of difficult access by the means of transport because these eyelets are held up and open separately must be so that an intervention by the means of transport, such as the fork a forklift is possible.

The object of the invention is to provide a large container for the transport and storage of insulation products, especially mineral wool products in the form of plates or rolls create which is simple and inexpensive to manufacture and in a simple manner without a pallet specially designed for each large container can be transported, whereby secure and fast access for a preferably conventional transport device, such as Forklifts for the purpose of transporting large containers must be guaranteed.

This object is achieved by the characterizing part of the claims 1 and 2 contained features solved, expedient training through the features specified in the subclaims are characterized.

According to the invention, several stacks are combined into one large container, about a large bundle of two stacks arranged side by side, each The mineral wool products are stacked one above the other in the form of individual plates or plate packs as well as individual roles or modules from multiple roles, and at least one eyelet-like grip loop is formed in the region of each stack. The Formation of these eyelet-like grip loops can be done, for example, on the main surfaces the stack placed next to each other and attached to the shell of the stack Web of tensile fabric or tensile film can be formed, which in itself Form loop-like grip loops. It is useful if one for each stack eyelet-like grip loop is provided. In the case of a large container, stand out of two stacks then two eyelet-like grip loops are available, for example from the two Forks of a forklift can be gripped. The is expedient placed web of fabric or film is made of the same material as the material of the cover, that surrounds each stack. It goes without saying that the eyelets are suitable for transport Are spaced from each other within a large container.

According to a further alternative embodiment, in which all the stacks are expediently of the large package are wrapped together by a single fabric web, the Formation of the loop-like grip loops by one in the parting plane of the side by side arranged stacks of looped through the fabric web, which then corresponding is folded over or is spread over the main areas of the stack.

Here, just as in the embodiment described above, through the fabric web the eyelet-like grip loops are formed. Again, it is possible in a very simple way Way to form the loop-like grip loops with formation of the shell of the stack in one.

To a gaping of stacks arranged side by side that lead to a large container are summarized to be prevented by a lifting device during transport, it is expedient if the grip loops are arranged off-center and offset inwards are. This inevitably results in a torque when lifting the large container, which acts on each stack and pushes it towards the parting line.

The grip loops can expediently be made by inserting or supporting appropriate ones Stiffeners may be reinforced or stiffened. The stiffening is also possible through multi-layer training. This can also result in stiffening the web used to form the handle loop is achieved is gathered and bound into a strand-like structure. This results in also a comparatively stable grip loop, so that a self-acting intervention the means of transport is possible without the handle loops being held by an assistant Need to become.

In a particularly advantageous manner, each stack can be covered in a moisture-protected manner, for example, by placing a trough-like dense hood in the lower region of each stack which is particularly expedient within the envelope from the fabric web or the film is included. Expediently, the front ends can also of each stack can also be covered with a fabric sheet or a film.

Figure 2

an analog schematic side view of another embodiment of the large container, also from two stacks arranged side by side.

In the embodiment according to FIG. 1, two stacks 1 and 2 are generally one with 3 designated large containers. Each stack 1 and 2 is made along the main faces mineral wool panels arranged one above the other. The number of one above the other arranged mineral wool insulation boards is selected depending on the application, so that any number of mineral wool insulation boards can be arranged one above the other. The Mineral wool boards within each stack 1 and 2 are designated 4. Every stack 1 and 2 is over its circumference with a web of tensile fabric or tensile film wrapped, which is designated here by 5. It is possible that each stack 1 and 2 in a sheath 5 made of a single web of fabric or film is arranged, expediently, however, the stacks 1 and 2 are wrapped with one and the same Fabric web that is wrapped so that it completely envelops each of the two stacks 1 and 2. Such wrapping techniques are well known and there are no difficulties to wrap both stacks here in total by a common path.

For the purpose of transport, one of 6 is on the large container from the two stacks 1 and 2 designated web of tensile fabric or film arranged, the appropriate way can be made of the same material as the wrapper. According to the illustrated The exemplary embodiment is the web 6 on the two upper main surfaces of the stacks 1 and 2 arranged and by gluing, welding or sewing and the like firmly with the Shell 5 of the two stacks 1 and 2 connected. In the areas marked with 7 is however the web 6 is not connected to the sheath 5, rather there are loop-like handles loops 8 and 9 formed. This can be achieved in the simplest way by the stretched Fabric web 6 is slightly pushed together in the areas 7, so that automatically forms an eyelet-like grip loop. If necessary, can be used to form the handle loop However, a mold core can also be used, which is then after gluing or Welding the web 6 with the sheath 5 is removed again, so that the eyelet-like Handle loops 8 and 9 are formed.

An alternative embodiment to FIG. 1 is also shown, in which the web 6, such as marked with dashed lines around the upper corners of stacks 1 and 2, so that the fabric web 6 at 10 and 11 partially overlaps the sides of the stacks 1 and 2, what for a stable connection of the large container is an advantage. It goes without saying that the web 6 in the areas 10 and 11 is also fastened to the cover 5.

The eyelet-like grip loops 8 and 9 are in the embodiment of Figure 1 from the Center of each stack, which is indicated by the dashed level 12, inwards offset, as is illustrated in the left stack 1 by the level 13, which is approximately in the middle with the handle loop is aligned. This has the consequence that when a transport by a forklift that is lifting large containers, one by the arrows D Illustrated torque acts counterclockwise inwards, so the two The stacks are practically compressed when they are lifted and do not diverge can. This is a useful measure, but it is not mandatory is. In other words, the grip loops 8 and 9 could also be centered or off-center be arranged towards the outer edges of the stacks 1 and 2.

In the embodiment according to FIG. 2, there is a single one for the casing of the two stacks 1 and 2 Fabric web used, the same components with the same reference numerals are designated. It goes without saying that in the contact area between the two Stacks 1 and 2 are two layers of web 6 made of tensile fabric or film, when each stack 1 and 2 is wrapped and wrapped with a single layer of the web. Here, as is indicated by the vertical arrow in FIG. 2, the web 6 during after wrapping the two stacks 1 and 2 in the form of a tab-like loop 14 pulled up, the two loop halves 15 and 16 then being pulled apart, as indicated by the arrows S. The left loop half 15 is as indicated by a dash-dotted line for the transition phase, to the left the main surface of the stack 1 placed, however, the right half of the loop 16 on the right Stack 2. This is again shown on the left with arrow T. The loop halves 15 and 16 then lie on the upper main surfaces of the two stacks 1 and 2 and are there, again with the formation of the eyelet-like grip loops 8 and 9, fastened with the sheath 5, what suitable, such as by gluing, welding or sewing and the like can. It goes without saying that as a result of the folding, the two lying on top and the two eyelet-like ones Grip loops 8 and 9 forming two-layer web and thus reinforced is. Here, too, the tab-like loop 14 can of course be pulled out for so long be that the upper fabric web again designated 6 also the two edges stacks 1 and 2 overlap analogously to the embodiment according to FIG. 1, which is for reasons of stability depending on the weight of the large container is an advantage.

In a further embodiment, it is expedient for the grip loops 8 and 9 to be of reinforced design are. In the embodiment according to FIG. 2, this can be done, for example, by that between the two layers for each loop half 15 and 16 a corresponding one Reinforcing fabric embedded and, if necessary, also firmly with the fabric web 6 is connected. It is also possible, however, that in the area of both grip loops expediently in adjacent areas, the fabric web 6 into a strand-like Formed together and bound, which results in strand-like grip loops. Finally, it can be expedient for the one used to encase the two stacks Film has longitudinal reinforcements, practically like "braces" in the Foil, which makes it less thick.

Depending on the intended use, it may be preferred to make the two stacks 1 and 2 weatherproof overall to be wrapped by a film or a fabric, so that even in the view of the figures 1 and 2 end faces to be seen from the front as well as the rear end faces can be covered or covered with a film or fabric. If necessary, it is too possible if in particular in the lower area of each stack 1 and 2 a trough-like Hood made of film or fabric is provided, which is designed as weather protection and is designed. This trough-like, tight hood can then be accommodated within the casing 5 his.
