DE4335544C2 - Transport and storage pallet for scaffolding frames - Google Patents

Description

The invention relates to a substantially rectangular, with on the floor adjustable foot parts Storage pallet for a number of essentially rectangular ones Scaffold frames that are upright with the pallet width direction parallel frame level successively in the longitudinal direction of the pallet Can be placed on the pallet and set up on it are held and at their upper end approximately in the pallet width appropriate distance from each other two upstanding connection have cones.

Such scaffolding frames usually have two side Longitudinal bars tubular in shape, open at the bottom and above are provided with the respective connecting pin, so that when Erecting a scaffolding two each in height following frames using the upper connecting pins and the lower tube openings of the longitudinal spars can be plugged into one another.  

For the orderly storage and transport of such frames are for example from DE-GM 90 15 913 pallets of the beginning mentioned type on the market, the two pallets longitudinal side holding devices for the free-standing frames exhibit.

A lot of frames are required for scaffolding. Dement speaking, the contractor must have a very large frame can store a lot. Therefore, the pallet according to the DE-GM 90 15 913 provided that the frame with large Packing density practically next to each other on the pallet represents are.

The present invention is based on the object To create pallet according to the preamble of claim 1, with their Help on the same footprint even more than since then can be accommodated. The purpose of this is necessary measures be as simple and robust as possible.

This object is achieved in that the Foot parts are arranged in the area of the pallet corners in the longitudinal direction of the pallet across several frames stretch, in the cross section parallel to the pallet width direction L or U-shaped, the horizontal L or U U-bridge a support surface and to a lower floor surface of the respective foot section protruding L-leg or  the U-legs form lateral stop surfaces, and on their end facing the respective pallet corner Front stop as effective in the longitudinal direction stop surface have, such that several each of a pallet and units standing on top of each other are stackable by the foot parts of the range of each upper unit with its support surface on the end faces of the Connecting pins of the frame of the lower unit be set, the stop in the stacked state overlap the connecting pins of the lower unit Form anti-slip devices.

Thus, the pallet / rack units via the Ver binding pins of the frame are placed on top of each other, so that the required footprint is reduced accordingly.

Stackable pallets are for example from DE-GM 86 34 415 known per se. However, these pallets point over the load protruding posts onto which the next upper one Pallet is placed.

In contrast, according to the present invention, the cargo, d. H. the frames, the lower pallet as a base for the upper palette used. Since the foot parts are so long that they each on several connecting pins and thus on several Mount frame, you get in conjunction with the various stop surfaces still sufficient  Stability and good cohesion against slipping in the plane, although it is an arrangement with considerable Height.

The foot parts have a relatively simple shape, so that they can be manufactured inexpensively.

The L-leg or the U-legs are expedient of the foot parts on the bottom side directed obliquely outwards, which means the up put on the frame easier.

One obtains particularly simple and cheap foot parts that the foot parts of an angled sheet metal part ge be formed.

Another useful embodiment is that the Foot parts each with at least two spacers with Ab stood to the bottom of the pallet are arranged so that between the bottom of the pallet and the relevant foot section Gap allows for a fork lift arm is there.

An embodiment of the invention is now based on the Drawing explained. Show it:

Fig. 1 shows a pallet of the invention in a schematic perspective view of a mounted assembly frame (on the illustrated pallet total of 12 servo frames are placed, of which the clarity is characterized because but only one is inserted),

Fig. 2 two stacked pallets / adjusting frame-A units in side view according to arrow II in Fig. 1,

Fig. 3 shows a detail from Fig. 2 (dot-dash circle III) in an enlarged view, from which the bottoming can be seen one of the leg portions of the upper pallet to the assembly frame of the lower pallet with legs of the U is cut away from the foot part which faces the viewer, and

Fig. 4 shows the arrangement of FIG. 3 in section along section line IV-IV.

The best seen in Fig. 1 emanating Transport and storage pallet 1 (with the stacked arrangement of FIGS. 2 to 4, the lower range by the reference numerals of FIG. 1 and the upper identically configured pallet just substituted with the same reference numerals however, with the addition of an "a") has a substantially rectangular shape with two longitudinal bars 2 , 3 each extending on one of the pallet sides in the longitudinal direction and two transverse bars 4 , 5 connecting the end regions of the longitudinal bars and extending in the pallet width direction . The longitudinal bars 2 , 3 and the cross bars 4 , 5 are made of structural steel profiles, in the practical embodiment of right corner profiles, which are welded together. The other components of the range are also structural steel parts.

This pallet 1 is used for transporting and storing a number of scaffolding frames 6 , which are essentially quite angular and upright with the frame plane parallel to the pallet width direction in the longitudinal direction of the pallet successively adjustable on the pallet and held on it in the erected state. The setting frames 6 are part of a scaffolding and have an essentially rectangular shape with two lateral vertical struts 7 , 8 , the spacing of which corresponds approximately to the pallet width. The two not only in their standing on the pallet position but also within a created scaffolding vertical struts 7 , 8 are formed by tubular rods material, so that the vertical struts 7 , 8 are open at their lower end 9 and have an insertion opening. At the upper end of the setting frame 6 , two upstanding connecting pins 10 , 11 are arranged approximately at a corresponding distance from one another, which are attached to the two vertical struts 7 , 8 in the exemplary embodiment. With the help of these plug pins 10 , 11 and the plug-in openings provided on the lower strut ends, the setting frames 6 can be plugged onto one another by plugging the respective upper setting frame with its lower vertical strut ends onto the connecting pins 10 , 11 of the setting frame located below. In this way, scaffolds of virtually any height can be erected. In the position of use, ie with the scaffold erected, the frames are in front of the building wall and are at right angles to the frame level. The vertical struts 7 , 8 are rigidly connected to one another by crossbeams 12 , 13 , which in the exemplary embodiment are arranged in the region of the lower and the upper end of the vertical struts. An accessible amount of scaffolding can be placed on these crossbeams 12 , 13 when the scaffolding has been erected.

On the two lateral longitudinal spars 2 , 3 of the pallet 1 , a row of plug pins 14 and 15 is arranged. Each pin 14 of the row of pins on one side of the pallet is opposite a pin 15 of the row of pins located on the other side of the pallet, so that there is a paired assignment, each pair of pins 14 , 15 serving to hold one of the frames 6 . This is done by plugging the frame onto the two plug pins 14 , 15 . For this purpose, the diameter of the plug pin 14 , 15 corresponds approximately to the diameter of the connecting pin 10 , 11 , so that they fit into the existing at the lower frame end and in the embodiment formed by the tube material of the vertical struts 7 , 8 insertion openings. In the plugged-on state, the setting frames are supported on the side rails 2 , 3 of the pallet 1 .

If one has an adjusting frame 6 inserted on all plug pairs 14 , 15 , the result is the arrangement shown in FIG. 2, in which the adjusting frames 6 stand freely next to one another in close succession.

It is now further provided that several units can be stacked on each other from a pallet and the ge standing on this frame. Of Fig. 2 such successive set units are visible two. As already mentioned, an "a" has been added to the reference numbers belonging to the upper unit. This stackability is now explained in the following:

In the area of its corners, the pallet 1 has base parts 16 , 17 , 18 , 19 with which the pallet can be placed on the floor. In the exemplary embodiment, there is one foot part in the area of each pallet corner, but in principle it could also be a continuous foot part on each cross member side. In pallet width direction of the leg parts are at a distance from each other, the connection pin to the distance of the adjusting frame Ver 10, 11 corresponds, so that the base parts of each weils upper pallet 1 a to the connection pins 10, 11 of the positioning frame 6 of the lower pallet assembly frame -Unit can be put.

The foot parts 16 , 17 , 18 , 19 have a longitudinal shape in the longitudinal direction of the pallet with a length that extends over a plurality of positioning frames 7 , ie over a plurality of plug pins 14 , 15 , so that they are stacked on a plurality of positioning frames arranged next to one another and at different positions 6 belonging Ver connecting pins 10 , 11 sit on. In the case shown, the foot parts each extend over a four spigot speaking length, but this number can also be chosen differently. Since the upper pallet in each case weighs heavily on the frame of the lower unit, the frames gripped by the foot parts of the upper pallet are, so to speak, connected to one another. In this way, stable assembly frame arrangements are obtained at the pallet ends.

Each foot part forms with its lowermost surface a floor standing surface 20 which can be set on the floor and above this a supporting surface 21 which, in the stacked state, rests on the end surfaces of the frame connecting pins of the lower unit. Furthermore, stop surfaces 22 , 23 , 24 are present on the foot parts, which overlap the connecting pins 10 , 11 of the lower adjusting frame in the stacked state and thus secure the upper pallet / adjusting frame unit against slipping to all sides.

In the exemplary embodiment, the foot parts 16 , 17 , 18 , 19 have a U-like shape in the cross section parallel to the pallet width direction ( FIG. 4), the horizontal U-web supporting the support surface 21 and the U-legs projecting downwards form two lateral stop surfaces 22 , 23 . The connec tion pin 10 , 11 of the lower pallet / frame unit thus engage from below in the U-shaped foot part, so that a U-leg or a stop surface 22 , 23 is adjacent to them on both sides. The lower edge of the U-legs forms the floor space 20 .

Instead of a U-shaped cross section, the foot parts could in principle also have an L-shaped cross section, whereby in this case the foot parts of one side of the pallet and the Foot parts of the other side of the pallet are mirror images of each other  with respect to the longitudinal center line of the pallet should be in order.

However, the U-shaped design ensures something greater stability of the stack.

The U-leg (or the L-leg with L-shaped cross-section) of the foot parts can be directed obliquely outwards on the bottom side, so that the insertion of the connecting pins 10 , 11 results in lighter inclined surfaces 25 , 26 .

The distance between the two U-legs 22 , 23 is chosen so that the respective upper range can be attached to the connecting pin of the lower unit without particular difficulty, but on the other hand it should not be too large.

It is further provided that the foot parts 16 , 17 , 18 , 19 at their end facing the respective pallet corner, which is somewhat upstream of the respective outermost plug pin 14 or 15 of the facing plug pin row in the longitudinal direction of the pallet, have a front stop as a stop surface 24 effective in the longitudinal direction . This stop surface 24 is formed in the game Ausführungsbei of a piece of material 27 running over the U-cross section of the foot part. A corresponding stop surface could also be provided for foot parts with an L-shaped cross section.

In the exemplary embodiment, the foot parts 16 , 17 , 18 , 19 are formed by a correspondingly angled sheet metal part.

The pallets can be lifted with a forklift. In this context it can also be provided that the foot parts 16 , 17 , 18 , 19 are each arranged at least two spacers 28 , 29 at a distance from the underside of the pallet, so that between the underside of the pallet and the foot part affect the one Retraction of a forklift arm ge available space 30 is present. The two spacers 28 , 29 are so far apart in the longitudinal direction of the pallet that the forklift arm can engage.

One of the spacers, which faces the relevant pallet corner, can be formed by a welded to the end of the pallet longitudinal spar 2 or 3 , which protrudes upwards over the longitudinal spar and at the same time the outermost plug pin 14 or 15 of the relevant plug row of cones.
