Description

The invention relates to a transport arrangement according to the features in the preamble of claim 1.

Mobile fencing is used to temporarily block and secure construction sites and venues, for example. These consist of barred frame-shaped fence elements, the lateral standpipes are inserted into heavy support feet made of concrete, metal, plastic or recycled material. In a holding foot two adjacent fence elements can be inserted.

In the prior art, a transport device for fence elements, for example by the DE 195 40 282 A1 known. This transport device has all the features of the preamble of claim 1. For the transport from and to the place of use, transport pallets which are generally oriented specifically to the type of fence element are generally used, in which in each case an end-side standpipe of each fence element faces upwards Holder arrangements is inserted. The holder assemblies may be formed of a plurality of juxtaposed pipe socket or cylindrical pins, in which the pipe ends of the uprights are either plugged or on which the pipe ends are plugged. The support feet are transported with separate transport devices.

From the DE 698 01 171 T2 goes out a transport pallet, which has two base plates, which extend at the height of the transverse and longitudinal struts.

Of the GB 2 303 353 A is a palette with retractable side walls removable.

When building a fence, it is first necessary to lay out the support feet. These can not usually be designed so precisely that the fence elements can be inserted in the next step without subsequent displacement of the support feet in this. Rather, it is necessary in particular for longer Zaunstrecken to displace the support feet. Another disadvantage of this approach is that the pre-designed support feet without inserted fence elements constitute an obstacle and a source of accidents for passers-by and workers. In addition, the entire fence length must be traveled twice, once with the support feet and the second with the fence elements.

The invention has for its object to provide a transport arrangement, created in the use of fence elements and support feet Zaunstrecken can be built and dismantled faster.

The object is achieved by a transport arrangement with the features of claim 1.

The transport arrangement comprises at least one fence element, at least one holding foot and a transport pallet, in which upwardly directed holder arrangements are provided for plug-in receptacle of pipe ends of the standpipes of the fence elements. The essence of the invention is that the retaining foot arranged on the transport pallet and the fence element is attached above the retaining foot on a holder assembly.

As a result, both the fence elements and the support feet can be transported and stored together. There are therefore no additional pallets required for holding feet. In this way space can be saved during storage and during transport on vehicles. Of course, additional components for barriers on the transport pallet can be stored and carried.

The construction of a mobile fence is much easier and safer because the fence can be installed in one go. Immediately after the two support feet have been placed on the ground, a fence element can be inserted, which is removed from the same transport pallet as the support feet. The tedious and cumbersome dislocation of the support feet is eliminated. The fence can be built in a much shorter time. The fact that the support feet no longer have to be designed separately, they can not be in the way and be an obstacle or accident risk.

Fence elements according to the invention are both grid elements made of metal or plastic with a height of 1.75 - 3 m as well as lower jambs with a height from about 1 m. The lengths can vary between approx. 1 m and 3.5 m.

The distance between the lower edges of the inserted fence elements in a section between the stanchions of a fence element and the pallet base corresponds to at least 1.2 times, preferably 1.5 times, the free length of the pipe end.

Due to the additional space, the loading of the transport pallet with support feet is much easier. A slight tilting of the support feet when hanging up is possible. In addition, it is possible to store several layers of support feet on the transport pallet from 2 times the free length of the pipe ends. This is especially for shorter transport pallets for shorter fence elements or barriers advantageous since full load for the construction of the on the Transport pallet stored fence elements required number of holding feet does not fit in a location on the transport pallet.

The longitudinal spars and crossbars of the transport pallet form a horizontal, rectangularly configured supporting frame. Between the longitudinal beams and the cross struts extends a pallet floor, can be stored on the support feet.

Advantageous embodiments and further developments of the inventive concept are the subject of the dependent claims 2 to 23.

The transverse bars and the longitudinal bars in the sense of the invention can be both profiles with an open cross section, in particular L, T, or C profiles, as well as profiles with a thin-walled hollow cross section, preferably a rectangular cross section.

At least one transverse spar can have an L-shaped cross section. In the case of an outer cross member, the L-shape makes it possible to drive a pallet truck into the transport pallet under the outer cross member and thus move the transport pallet on a level surface with the lifting fork raised. Due to the length of the transport pallet may need to be provided on both ends transverse bars with L-shaped cross-section to lift the pallet with pallet truck and move.

The longitudinal beams and transverse beams can be arranged in one plane. The arrangement in a plane of the support frame is flatter and the pallet floor can be made even. In addition, the pallet floor can be made in one piece.

The transverse spars may extend over the entire width of the support frame and be arranged at a distance for receiving a forklift fork. Often transport pallets of this kind are moved with forklifts. In order to facilitate the transport, it is advantageous if the forklift fork can be inserted from all four sides into the supporting frame of the transport pallet. Furthermore, in this embodiment, the transport pallet width of the Forklift fork can not be adjusted if the transport pallet is to be lifted from the front instead of the long side.

In addition, the support frame may be stiffened by flat iron against bending in the longitudinal direction. The transport pallets are loaded by the fence elements and the holding feet by a considerable weight. To ensure the stability of a fence, the support feet have a high weight. Since a variety of support feet is charged, the total weight is often more than 1.4 t. Especially when the support feet rest at a greater distance to the center of gravity on the transport pallet, a high bending load of the transport pallet occurs. Under these conditions, the stiffening effect of the flat iron advantageous. In addition, the flat bars can represent a lateral boundary of the transport pallet and prevent holding feet from slipping off the transport pallet.

It is advantageous if at least one of the holders is releasably connected to the support frame. By replacing the brackets fence elements can be stored and transported with different pipe ends on the transport pallet. Conveniently, the mutual distance of the holder assemblies for adaptation to different length fence elements can be varied. Thus, different lengths fence elements can be transported on the pallet. It must therefore not be maintained for each type of fence element own transport pallets. The transport pallet according to the invention is individually adaptable. To implement the brackets, the flat bars may have a plurality of holes arranged in the longitudinal direction of the longitudinal beams at a distance from one another for plug-in fastening of a holder arrangement. It is also advantageous if the bearing bolts can be inserted from the inside and do not protrude beyond the side edges of the support frame. Since the width of the loading area of trucks is limited, so the full width of the transport pallet can be optimally used.

The holder assemblies may be pivotally mounted on the support frame. For fixing the holder arrangements, in particular, the above-mentioned lateral flat iron offer. Due to the pivotable storage, the Holder assemblies are pivoted between an upright position to the socket of pipe ends and a lying position in the direction of the pallet base. When empty, the holder assemblies can be folded so that they can be easily stacked. This saves transport volume. Furthermore, the retracted holder assemblies pose no risk of accidents.

Conveniently, the holder assemblies each have a locking element can be assigned, which prevents pivoting of the holder assembly beyond the upright position. This facilitates the attachment of the fence elements and increases transport safety.

The holder assemblies may comprise trusses, on which plug-in elements are arranged for plug-in receptacle of the pipe ends, each truss having two plug-receiving portions, and having a disposed between the plug-receiving portions central region. The plug-in elements are arranged only in the plug-receiving areas.

The plug-in elements for plug-in receptacle of the pipe ends can be designed sleeve-shaped or peg-shaped. However, it is simple and expedient if the plug-in elements for the plug-in receptacle of the pipe ends are angle iron or flat iron.

The pipe ends of the fence elements may be mutually plugged into one of the holder assemblies. The free pipe ends of the fence elements lie on the traverse of the opposite holder assembly. Thus, length tolerances can be compensated because the fence elements have a different length and the pipe ends can be bent.

The pallet floor may be formed of sheets attached to the longitudinal beams and the cross beams. In addition, the pallet floor may have water drainage openings. These prevent freezing of the support feet in winter and corrosion of the pallet base. Perforated sheets are considered to be particularly suitable. But there are also pallet floors made of wood, plastic, meshes, mats or bars conceivable. The pallet floor can be, for example be attached to the upper edge of the longitudinal beams and transverse beams or at the lower edge thereof. But it is also conceivable that the pallet base rests only on the support frame.

End plates on the holder arrangements can be arranged. In particular, in the case of circular plug-in elements pivoting of the fence elements around the longitudinal axis extending in the direction of the tube end is possible, as a result of which a fence element resting on the second holder arrangement could slide down from its traverse. Therefore, it is advantageous to provide a cover plate at least at one outer end of each cross member.

Longitudinal beams or transverse struts and the pallet base extending between them can be made in one piece from a multi-folded metal sheet. This embodiment enables a particularly cost-effective and simple production of the transport pallet. The transport pallet consists essentially of three sections, two side parts and a middle part, which are welded together. All parts have the same cross-section and can therefore be manufactured very efficiently.

It can be provided inner and outer longitudinal beams, wherein the inner longitudinal beams are carried out by a resting on the cross beams longitudinal angle iron and a fixed to the lower edge of the transverse beams lower flat iron and a longitudinal angle iron and the lower flat iron spaced support plate. In this embodiment, it is possible to raise the transport pallet from the sides with a pallet truck on a level surface. The pallet truck can be pushed laterally with the front rollers over the lower flat bars. In the inserted state then the lifting fork of the truck can be raised. It then raises the transport pallet so that the transport pallet can be moved with the pallet truck.

In the FIGS. 1 and 2 is a transport pallet 1 for fence elements ZE shown. Longitudinal beams 2, 3 and transverse beams 5, 6 form a horizontal rectangular configured support frame 7. The front side upwardly directed holder assemblies 8 are arranged for plug-in receptacle of tube ends RE of the uprights SR of fence elements ZE. Between the longitudinal beams 2, 3, transverse bars 5, 6, a pallet base 9 of perforated plate, which is attached to the upper edge 16 of the support frame 7 extends.

The dimensions of the transport pallet 1 are determined in the length L by the transportable fence elements ZE and in the width B by the width of the loading area of trucks. The fence elements ZE can have a length between 1,400 mm and 3,500 mm. The width of the loading area on trucks is usually 2,000 mm, so that two per 1,000 mm wide transport pallets 1 side by side on a loading space have space. The dimensions of the transport pallet 1 in FIG. 1 are 3,500 mm x 1,000 mm.

The longitudinal beams 2, 3 and inner cross members 5 of the support frame 7 consist of a rectangular profile with the dimensions 160 mm x 80 mm x 4 mm. The outer transverse beams 6 are formed by an L-shaped profile with the dimensions 100 mm x 55 mm x 5 mm. The inner cross members 5 extend between the sides 10, 11. They have an outer dimension AM vpn 1,000 mm, so that the transport pallet 1 can be picked up by a forklift truck from all four sides, without having to change the width of the forklift fork. On the longitudinal sides 10, 11 flat iron 13 are attached to the upper edge of the support frame 7, which prevent bending of the transport pallet 1 in the longitudinal direction. The outer transverse beams 6 and the lateral flat iron 13 also serve to limit the transport pallet 1 in particular for the lying on the transport pallet 1 material. At the end faces in each case three stop tabs 12 are provided for the attack of crane hooks or chains.

At the front-side holder assemblies 8 angle iron 14 are provided for plug-in receptacle of pipe ends RE of the fence elements ZE. In other embodiments of the transport pallet 1, flat iron can also be provided instead of the angle iron 14. In this embodiment, there are ten angle iron 14 on a cross member 15 of each holder assembly 8 in plug-receiving areas SAB. Between these plug-in areas SAB, a free middle area MB is provided. Fence elements ZE can be inserted from the top of the angle iron 14, in each case only one pipe end RE of a fence element ZE is plugged and the other end of the pipe RE on the cross member 15 of the opposite holder assembly 8 comes to rest. For this purpose, the angle iron 14 between the holder assemblies 8 are mutually offset. In the middle area MB, a chain of a crane can be struck on the trusses 15.

In FIG. 2 is a plugged onto the holder assemblies 8 fence element ZE shown. It is recognizable that the support frame 7 comprises longitudinal bars 2, 3, which are interrupted by inner transverse bars 5. The longitudinal beams 2, 3 and the inner cross members 5 are thus arranged in a plane. At the upper edge 16 of the support frame 7, a flat iron 13 is attached. This flat iron 13 has a plurality of bores 17, 18 at a lateral distance in the longitudinal direction. At these holes 17, 18, the holder assemblies 8, which are located in this representation, the front side, are releasably secured. They are pivotable between an upright position and a lying position in the direction of the pallet base 9 (arrow P). Through the holes 18, which are located about one-third and two-thirds of the length L of the transport pallet 1, in particular ensures that not only fence elements ZE, but also shorter and flatter barriers with the transport pallet 1 can be transported.

In FIG. 3 the holder assembly 8 and its attachment to the support frame 7 is shown enlarged. In the lower level is the support frame 7. It is a longitudinal beam 2 shown, on which concealed an outer cross member 6 and upright a flat iron 4 with the dimensions 50 mm x 5 mm is arranged. The long leg of the angle profile of the outer transverse spar 6 is welded to the upper edge 16 of the longitudinal spar 2. On the longitudinal beam 2 upright a flat iron 13 is welded. This flat iron 13 has at its end three bores 17 at a lateral distance from one another in the longitudinal direction. Hidden behind the holes 17 is a bearing bar 19. The holder assembly 8 is held in the outermost bore 17 by a bearing pin 20. The holder assembly 8 comprises a cross member 15 made of a square tube. End side of the crossmember 15, a side part 21 is arranged, which extends in height above the traverse 15 addition and also acts as a cover plate 22 in this illustration. At the lower end of the side part 21 is a locking element 31, which prevents pivoting of the holder assembly 8 beyond the upright position. On the crossbar 15 angle iron 14 are attached ( FIG. 4 ). On the front side three stop tabs 12 are provided to stop crane hooks or chains.

The height HW of the angle iron 14 is shorter than the length of the pipe ends RE, which are placed on the angle iron 14. The distance A measures the height of the holder assembly 8 above the pallet base 9, which is attached to the upper edge 16 of the support frame 7. The distance A is greater than 1.2 times the height HW. In this case, the distance A is 3 times the height HW.

In the FIG. 4 is the frontal attachment of the holder assembly 8 shown on the support frame 7. The holder assembly 8 comprises a plurality of angle iron 14 arranged on a traverse 15. The traverse 15 consists of a square tube. On the crossmember 15, a side part 21 is fixed, which extends in height above the height of the cross member 15 also and acts as a cover plate 22 in this area.

The holder assembly 8 is mounted on the support frame 7 via a bearing 24. The support frame 7 is in FIG. 4 formed by a longitudinal spar 2 and an outer transverse spar 6 attached thereto. On the longitudinal beam 2, a front-side flat iron 4 and a lateral flat iron 13 is attached to the upper edge 16, the latter having a bore 17. The flat iron 13 is on the inside a bearing bar 19 is assigned at a distance, the three holes 25 in the longitudinal direction, of which only one is visible, located at the holes 17 in the flat iron 13 corresponding points. The bearing bar 19, the flat iron 13 and the side part 21 are penetrated by a bearing pin 20. Between the flat iron 13 and the side part 21, a disc 29 is placed on the bearing pin 20. The bearing pin 20 has a bore 27 into which a spring pin 28 is inserted. By the spring pin 28 of the bearing pin 20 is secured against axial displacement. After the spring pin 28 has been removed, the bearing pin 20 can be pushed in the axial direction out of the bearing 24 to allow the holder assembly 8 to be moved. For the attack of a crane hook or chains a stop tab 12 is shown.

In the Figures 5 and 6 is a variant of the transport pallet 1 of FIGS. 1 and 2 shown. For identical features, the same reference numerals are used. In FIG. 5 was used instead of the inner longitudinal members 3, a longitudinal angle iron 29 with the dimensions 100 mm x 50 mm x 5 mm, which is welded to the long leg on the inner cross bars 5. The pallet base 9 has been adapted in its width. Additionally, in FIG. 6 attached to the lower edge of the inner transverse beams 5 below the longitudinal angle iron 29 lower flat iron 30 by welding. Support plates 32 secure the lower Flat iron 30 against kinking. With this variant, it is possible to lift the transport pallet 1 from the longitudinal sides 10,11 ago with a pallet truck.

On the transport pallet both fence elements and support feet can be stored and transported. Because the space below the fence elements is better utilized, the volume required to transport and store mobile fences can be reduced. The transport pallet according to the invention ensures that fence elements and support feet and other accessories are always transported together and in particular that the construction of a mobile fence in one pass is possible. The personnel and material costs are thus significantly reduced. In addition, the accelerated construction of the fence minimizes a potential accident risk.
