Description

The invention relates to a device for stacked storage and / or transporting a rigid flat frame showing, especially to be used on construction sites Objects, in particular scaffolding parts of a modular system scaffolding to be erected.

For example, those scaffolding parts that are essentially one rectangular frames are formed in different sizes. To store them in a stacked manner or to be transported, that's why Pa has been needed ever since Latvians of different sizes, each to the stacking scaffolding parts are adapted. This is cumbersome and expensive, since the respective palette is only for one can use certain scaffolding part size. Also are the pallets, with uprights at the corners, bulky Structures so that they are proportionate when not in use take up a lot of space.

It is therefore an object of the present invention to to create a device of the type mentioned with whose help is quick and easy Can make stacks regardless of the frame size, so that it is within the scope of its intended Act for the purpose of versatile use. This In addition, it should be easy to set up and cheap to manufacture be as small as possible, if it is not needed.

This object is achieved in that the device has at least one vertical in use position and stretch along one of the frames on top of each other extend leg-formed side surfaces of the stack the post, a support body arranged below for Place the facing frame leg of the lowest Object, a rear grip piece standing up from below for reaching behind at least that on the support body lying frame leg of the lowest object the side facing away from the post and one in Höhenrich adjustable on the post, on the facing th frame leg of the top object attachable and has this holding-down device, such that opposing each other by using several set side surfaces of the stack of attached devices results in a stable stack package.

It is therefore one of a few individual parts composite device, which is arranged in multiple arrangement  is used and in each case far less bulky than a pallet. The devices are opposed along the frame legs and then only needs to put in the lowest frame, according to which an unrelated the devices can be moved to each other. Subsequently put the other objects or frames on the be already inserted bottom frame until the desired Stack height results. Then only the Nieder holding devices brought into position, thereby a Zu together the frame is achieved in the vertical direction. The result is a stable package in which the Represent the frame itself, so to speak, load-bearing parts. The Stack packages can also be easily handled and are stackable on top of each other. You can, for example by means of a forklift, which is the lowest frame underrun, lift up. If a crane is to be used for this, you can either attach the suspension cable to the frame holding devices or attach to the frame. Because of the solid cohesion of all individual parts of each Package is both possible.

Above all, the same devices can be used for stacking objects of different dimensions turn. This is because now none there are more basket-like containers or corner posts, but only posts arranged on the frame legs. If the frames are wide, you can create them devices assigned to opposite frame sides speaking farther apart than narrow ones  Frame. The frame length also doesn't matter. Will packaged longer frames, they just stand further over those arranged on their longer frame legs Devices.

Advantageous embodiments of the invention are in the Subclaims specified.

An embodiment of the invention as well as in the Measures specified in subclaims are now based on the drawing. Show it:

Fig. 1 shows an inventive device in front view,

Fig. 2 is a composite with the aid of two devices according to Fig. 1 of scaffolding parts stack package in plan view from above,

Fig. 3 shows the arrangement according to Fig. 2 position in vertical section according to the line III-III in Teildar,

Fig. 4 shows a variant of the device according to FIGS. 1 to 3 with a cross member variable in length and

Fig. 5 shows another variant in plan view from above.

The device shown in the drawing is used for stacking and / or transporting objects that have a rigid, flat frame. Devices of this type are required in particular in the construction industry, especially for scaffolding parts of a scaffolding to be constructed in a modular manner from a circumferential frame. Such a scaffold part 1 can be seen in FIG. 2. It has its rectangle shape corresponding to two opposite longer frame legs 2 , 3 and two opposite shorter frame legs 4 , 5 . Such scaffolding parts 1 can be set up vertically and can be attached to one another with aligned frame legs 2 , 3 , as is generally known in the case of scaffolding, so that it need not be discussed further here. It is pointed out that the device presented Darge can not only be used for scaffolding parts, but always when, as already mentioned, a structure with a current frame is available.

The device 6 has at least one, in the exemplary embodiment two posts 7 , 8 , which extend vertically in the position of use. The two posts 7 , 8 are arranged at a distance par allel to one another, their bottom end regions being rigidly connected to one another via a cross member 9 extending at right angles to the post, so that there is a U-like appearance in the front view ( FIG. 1).

At this point it should be noted that if above and below spoken of "above" or "below" the usage situation in which the  Stand vertically and extend along one of the of superimposed frame legs formed sides Extend surfaces of the stack of items so that the The height direction coincides with the longitudinal direction of the post.

Two such devices 6 are placed against each other in use at a distance of the width (or length) of the frame, as can be seen in FIG. 2. There the two posts 7 , 8 belong to one device and the posts 7 ', 8 ' to the second device. Their trusses 9 are not visible, since they are covered by the frame legs 2 , 3 . The visible object 1 is the uppermost frame of the stack formed from superimposed frames, on the side surfaces in which the frame legs 2 , 3 of all frames run, a device is arranged, the posts 7 , 8 and 7 ', 8 ' thus the Stack side areas are assigned. By means of two such devices 6 , the stacked frames are firmly held together, so that a package-like unit results. The two opposing devices 6 are only connected to one another via the frame stack, so that the frame legs are supporting parts of the resulting package. Since the distance between the two devices can be chosen as desired, the devices can be used for frames with frame legs 4 , 5 of any length. Regardless of the distance between the two devices from one another, the other frame dimensions, ie the length of the other frame legs 2 , 3 , which extend parallel to the device crossbars 9 , can be arbitrary, since this only changes the overhang of the frames above the device posts.

With each device there is also a support body arranged at the bottom for placing the facing frame leg of the lowest object. In the expedient example, the traverse 9 is laterally attached to the two posts 7 , 8 and forms the support body mentioned, whereby it represents a continuous support over its entire length.

Furthermore, for each post 7 and 8 , the device 6 has a rear gripping piece, which stands up from below, for reaching behind at least the frame leg 2 or 3 of the lowest object lying on the support body 9 on the side facing away from the respective post 7 or 8 .

The respective rear grip piece, for example the rear grip piece 10 , is rigidly attached in the exemplary embodiment to the side of the support body 9 facing away from the post 7 , which in turn is rigidly arranged on the bottom end region of the post. As already mentioned, in the exemplary embodiment the support body is formed by the traverse 9 which runs continuously between the two posts; However, it could also be attached to each post, for example, an L-shaped bracket, the leg protruding from the post forming the support body and the upstanding leg facing away from the post forming the rear gripping piece. There are various options available to those skilled in the art. However, the one shown is particularly simple and practical, for example because the frame legs 2 , 3 cannot bend downwards because of the continuous crossmember 9 . The respective rear grip piece does not necessarily have to be arranged on a post. It is readily apparent that one could let two rear gripping pieces of the cross member stand up in the area between the two posts 7 , 8 of the cross member 9 .

The support body or the crossmember 9 is formed by a square tube. Like the other parts of the device, this consists of structural steel and is welded to the posts. The respective rear grip piece 10 or 11 is welded to the rectangular or square side of the square tube facing away from the post. The traverse 9 could also be a round tube.

As can be seen from Fig. 4, a varied cross member 9 a , which is only partially shown in Fig. 4, can be changed in length, so that the length of the device can be adjusted. For this purpose, the cross member 9 is composed of a two tele skopartig nested truss parts 12, 13 together. In order to be able to determine the respective longitudinal position, the inserted cross member 13 , for example, a row of holes 14 and the other cross member 12 in the region of its free end have a plug hole 15 , so that one through the plug hole 15 and in the desired longitudinal position with this plug hole 14 can insert a socket pin.

It should be noted in this connection - before the individual device 6 is further described - that the crossbeams 9 can be connected to one another by two struts 7 , 8 each having devices 6 via connecting struts in parallel distance. This is indicated in Fig. 5. For this purpose, the crossbeams 9 can be formed by a hollow profile piece that is open at both ends, so that one can insert ends 18 , 19 or 20 , 21 into the crossbeams 9 at the connecting struts 16 , 17 . Each connection strut 16 and 17 forms with the associated plug-in projections 18 , 19 and 20 , 21 a U-shaped connecting part. A safety bolt can be inserted through dashed holes in the crossbeams and plug-in projections. In this way, the devices can also be used differently than described, namely as pallet-like devices.

At the bottom end of each post 7 , 8 , a footplate 22 or 23 projecting laterally, in particular on the side of the rear gripping piece, is arranged, from which, at a distance from the post, a stiffening strut 24 expediently stands up at an angle to the support body (in the embodiment, for example, traverse 9 ) can. The stiffening strut is welded to the respective base plate 22 and to the support body or is otherwise rigidly connected. The large base plate 22 ensures a good stand, and the stiffening strut results in a stiff arrangement.

A particularly low-parts and simple construction is obtained if, as shown, the stiffening strut 24 protrudes upward above the support body and forms the rear gripping piece 10 or 11 with this projecting part.

On the at least one post 7 or 8 , a height-adjustable hold-down device 25 or 26 is arranged, which can be placed on the facing frame leg 3 of the uppermost object and holds it, thereby holding together the stacked objects in the height direction and thus overall results in a stable stack package, which is composed of the stacked objects and from the surfaces on the opposite sides of the stacked devices 6 .

In the exemplary embodiment, each post 7 or 8 carries such a hold-down device 25 or 26 .

Each hold-down device, for example the hold-down device 25 , has a rear grip portion 27 for reaching behind at least the frame leg 3 of the uppermost object of the stack, so that there is also a firm hold between the stack and the post in the horizontal direction.

On the underside of the holding-down device 25 , a recess 28 for engaging the frame member 3 can be formed on the side facing away from the post 7 from the rear grip portion 27 . The recess can, as Darge presents, be round, but it can also be prismatic. If the stacked objects are not thighs with a frame with a circular cross-section, but with objects with a different cross-section, the shape of the recess 28 should be adapted accordingly so that the frame leg can be reached from above.

Advantageously, the hold-down 25 (the same applies to the hold-down 26 ) and / or the support body 9 on the side facing the support body or the hold-down device a pressure piece 29 made of elastically deformable material, for example rubber-like material, which can be quite hard , on. In the practical embodiment, the pressure piece 29 is arranged on the underside of the hold-down device 25 . The pressure piece 29 has a pillow-like shape and acts, so to speak, as a buffer.

If the frames are stacked on top of each other, the hold-downs 25 , 26 are placed and pressed firmly downward, so that the pressure pieces 29 press against the facing frame legs 3 and nestle them somewhat. This elastic pressing has the following advantages:

The scaffolding parts are often used on construction sites, for example soiled by adhesive mortar. Now package it  the scaffolding parts for transport, it may be that the Scaffolding parts not tight due to the dirt adhering to them lie on one another. The dirt can then be transported crumble off, which gives you a rigid hold-down underside an only loosely vertically connected arrangement would get. This is ver by the elastic pressure piece prevents.

The hold-down 25 , 26 is continuously adjustable in height arranged on the post and in the respective position of use, when it is connected to the top frame, fixed by jamming or tilting on the post.

The hold-down device is plugged onto the post by having a plug-in opening 30 penetrated by the post.

The hold-down device is U-shaped in cross-section with side legs 32 , 33 projecting downward from the crosspiece 31 , on which the recess 28 for engaging the frame leg 3 and the rear engagement part 27 are formed. The pressure piece 29 is housed in the area of the hold-down protruding from the post inside the U. In this case - this also applies to hold-down devices of a different design - the pressure piece 29 protrudes a little into the recess 28 .

The plug opening 30 is contained in the crosspiece 31 . If you press the hold-down on the uppermost frame and if you apply a force from above to the rear gripping section 27 with respect to the post 7 opposite hold-down section 34 , the hold-down will tilt at the post. The insertion opening 30 at the front, ie facing the rear grip portion 27 , is only delimited at the top by the transverse web 31 of the U, while at the rear there is a rear wall 35 filling the U, between which and the post 7 a wedge body 36 can be driven vertically. The rear wall 35 is inclined corresponding to the wedge surface of the wedge body 36 . If the wedge body is hammered in, you get a hold-down clamped and tilted with the post, which holds firmly.

The wedge body 36 is arranged so that it cannot be lost, for example by welding a bracket 37 encompassing the rear wall 35 to its rear side.

The posts 7 , 8 shown have a square cross section. The insertion opening 30 of the hold-down device is shaped accordingly. With this design, the hold-down device can also be rotated by 90 ° and plugged onto the post, which can be useful for other device uses.

Are the post and the opening of the hold-down provided with a circular cross-section, the low holder can be turned around the post when not in use. This can be the case, for example, when stacking and unstacking  Items will be beneficial. So that the respective Hold-down does not prevent, you can simply swing it away ken. In the case of a rectangular or square cross-section you take it against it.

Another important point is that the devices 6 can be changed on one another, so that the stacked packages can also be placed on one another. For this purpose, in the execution, for example, at each post at the bottom end, a base plate 38 is provided with a downwardly projecting edge, which in the case of an exemplary embodiment of 39 , 40 , 41 and a transition from three sides protruding edge and a transition to the base plate 22 producing inclined region 42 is formed. The underside of the edge parts 39 , 40 , 41 lies in the same plane as the underside of the foot plate 22 . The edge parts 39 , 40 , 41 and the inclined area 42 enclose a placement opening 44 with which the post is placed on the upper end of the post of an apparatus below. The placement opening 44 is seen at least in the longitudinal direction of the crossmember 9 larger than the corresponding post dimension. This is useful because otherwise the four posts would have to form an exact rectangle for each stacking package. In practice, however, the two devices that are attached to a stack are usually somewhat offset from one another in the longitudinal direction. Despite this inaccuracy, the stack packs can be placed differently because of the larger attachment opening 40 with respect to the upper post end.

In a modification of the illustrated embodiment, each device could in principle consist of only one post with a support body, a rear grip piece and a hold-down device. Such an embodiment is obtained, for example, by removing the cross member 9 , from which only brief stubs are left on the two posts 7 , 8 as support bodies. At least four such posts would then have to be used for a stack package.

In the arrangement according to the drawing, the posts extend up the outside of the stack. However, one could also reverse the two devices by 180 °, so that the crossbeams 9 face away from the other device. In this case the posts would extend within the space enclosed by the stack.
