Definitions
- the invention relates to a support frame for several scaffolding decks with the features of the introductory part of claim 10, and a kit consisting of a support frame and at least two scaffolding decks with the features of the introductory part of claim 1.
- a support frame for scaffolding elements is known.
- the support frame has two stands spaced apart from one another, which can each be set up on a base using two support feet.
- the two support feet are connected to each other via a cross member.
- a stanchion extends upwards, which is firmly connected to the respective support foot.
- a holding device is also assigned to the stand, which is used to secure a scaffolding element on the respective stand in the vertical direction.
- the scaffolding element extends between two opposite, identical stands and is aligned horizontally and placed in the area of the support feet of the two stands.
- the holding device in the region of each stand is formed by an angle profile which is pivotably mounted on the cross member.
- the angle profile is pivoted from a release position pivoted outwards into a securing position horizontally overlapping the scaffolding element. Further scaffolding elements are then stacked on the bottom scaffolding element, whereby the weight of this stack of scaffolding elements supports the angle profile serving as a holding device in the secured position on the bottom scaffolding element.
- the respective angle profile is mounted centrally on an upper side of the respective cross member of the respective stand.
- the DE 195 03 721 A1 discloses a stacking aid for formwork elements or pallets.
- Each stacking aid is designed as a column that can be positioned in a corner area of a formwork element or a pallet.
- Each column-shaped stacking aid has a support foot from which an angle profile serving as a stanchion protrudes vertically upwards.
- Each stacking aid is provided with a pivotable safety pawl, which is pivotably mounted on a carrier plate between a release position and a functional position securing a building formwork element or a pallet.
- the support plate protrudes from the angle section parallel to the support leg, with a distance between the support plate for the safety pawl and a bearing surface of the support leg in the vertical direction being somewhat greater than a height of one building formwork element to be secured or a pallet to be secured.
- the safety pawl is inevitably pivoted from its release position into the safety position as soon as the stacking aid is pushed onto a corresponding corner of the building formwork element or the pallet.
- a total of four stacking aids are advantageously provided, each of which is placed over a corner area of a rectangular base area of the building formwork element or pallet.
- the support frame has a lower frame with a total of four support feet, which are firmly connected to each other via two crossbeams and two longitudinal beams to form a rectangular frame.
- a scaffolding floor is placed on this rectangular frame, which extends horizontally relative to a substructure, and can be positioned within the support feet.
- a cylindrical stanchion can be inserted into each support leg, which in the installed state protrudes upwards in the vertical direction from the respective support leg.
- Each support foot is formed by two receiving tubes arranged next to one another and aligned parallel to one another, with each stanchion being insertable either into an inner or an outer receiving tube of the respective support foot.
- the support feet are provided with funnel-shaped support mounts on the underside so that several support frames can be stacked on top of each other.
- the object of the invention is to create a support frame and a kit of the type mentioned at the outset, which enables particularly safe transport and reliable storage of scaffolding floors.
- a positively effective in the vertical direction Holding device provided for at least one scaffolding floor, which is associated with the stand.
- the holding device ensures that when the at least one scaffolding floor is raised, the at least one stand is also raised, so that the support frame including the at least one scaffolding floor can be lifted and moved by a forklift truck or similar transport device.
- the holding device ensures that when you reach under a corresponding scaffolding deck or a corresponding scaffolding deck stack that is arranged in the support frame, the corresponding lifting force via the holding device onto the at least one stand is transferred.
- the solution according to the invention is suitable for the storage and transport of scaffolding decks that are used in scaffolding and that form floor surfaces of scaffolding that can be walked on in the respective scaffolding storey.
- the solution according to the invention enables a large number of scaffolding decks to be safely stacked, which retain an exact stack shape even after prolonged storage and thus reliably avoid the risk of the scaffolding deck stack falling over.
- two stands are provided as separate components which are spaced parallel to one another in the ready-to-use state and are aligned in the vertical direction.
- the two stands and several scaffolding floors form a transport and storage unit that can be handled together.
- the two stands designed as separate components are designed to be structurally identical to one another.
- the concept of identical construction includes, on the one hand, an identical design of the stand and, on the other hand, a functionally identical design of the stand with mirror-symmetrically arranged but otherwise identical functional sections.
- the solution according to the invention is suitable both for scaffolding floors which are identical to one another and for differently designed scaffolding floors with the same or different widths.
- the support frame according to the invention is preferably made of metal parts, in particular steel parts, designed as a sheet steel construction, functional parts and functional sections that are correspondingly firmly connected to one another preferably being welded to one another.
- the support frame according to the invention can also be made from light metal components.
- the stanchions are preferably designed as square tubes, but they can also be designed in the same way as hollow or solid profiles with other rotationally symmetrical or rotationally asymmetrical cross sections.
- Corresponding mounts of the support feet for tool-free assembly of the stanchions are matched to the profile cross-sections of the stanchions in such a way that there is a plug-in connection between the stanchions and the corresponding mounts of the support feet.
- the stanchions are preferably inserted into the receptacles.
- the stanchions, as hollow profiles can also be attached to the outside of the support feet, which are designed as plug-in pins.
- a longitudinal support device for form-fitting support of at least one scaffolding deck in the longitudinal direction is assigned to the stand.
- Each of the stands each has a longitudinal support device.
- the respective longitudinal support device serves as a spacer for the symmetrical positioning of the uprights in the longitudinal direction relative to the scaffolding floors. This allows for an even weight distribution. This is because the corresponding configuration serves to prevent the at least one lower scaffolding floor, which rests on corresponding crossbeams of the stand, from slipping in the longitudinal direction. If the length of the cross member between the support legs of each upright is such that two scaffolding floors can be positioned in one tier between the support legs of each upright, then the longitudinal support means has a longitudinal support function for each of those scaffolding floors of the lowest tier.
- the cross member has a length which at least largely corresponds to an integer multiple of a width of a scaffolding deck or a stack of at least two scaffolding decks stacked on top of one another.
- the integer multiple is the number 2 or the number 3, so that the design enables two or three scaffold decks to be positioned side by side in a horizontal position on the crossbeams of the two spaced uprights.
- the distance between the two support feet of each stand, which at least largely defines the length of the corresponding crossbeam of the stand, is advantageously slightly larger than an integer multiple of the width of a scaffolding deck, in order to avoid jamming of the scaffolding decks when being put on or removed.
- the holding device has in each case a support web which protrudes radially from one support foot to the opposite support foot of the stand and which is arranged in the vertical direction at a distance from the cross member which corresponds to the thickness of a scaffolding deck or a stack of at least two scaffolding decks stacked on top of one another.
- each support leg is provided with a support web that protrudes toward the opposite support leg. If the stand is aligned vertically, ie vertically, on a base, the support bar extends horizontally from an inside of one support foot to the opposite support foot of the stand, so that the two support bars of a stand face each other. Both support webs are positioned at the same distance from a top of the cross member of the stand. The distance to the cross member for each support bar is chosen so that a scaffolding or two or three scaffolding floors in a common horizontal position next to each other on the
- Crossbeams can be stored, with the respective outer longitudinal edge regions of the scaffolding floor sections resting against the support feet reaching under the respective support web.
- the respective support web can also be attached to the support foot at a greater distance from the cross member, so that a stack of two or more scaffolding decks stacked on top of one another can be inserted between the cross member and the corresponding support web of the support foot.
- the longitudinal support device has at least one support section fastened to the post, which extends in the transverse direction and/or in the vertical direction in order to engage behind a holding section of a scaffolding floor in the longitudinal direction of the scaffolding floor.
- the support section therefore protrudes into a holding section of a scaffolding floor in such a way that there is a form fit in the longitudinal direction of the scaffolding floor, so that the scaffolding floor is prevented from slipping orthogonally to the longitudinal direction of the crossbeams of the uprights.
- the support section is designed as a metal bracket or as a metal web that is firmly connected to a support foot or to the cross member of the respective stand, preferably welded to the corresponding component.
- An undercut or a receiving groove of a suspension hook provided on the end face of the scaffolding floor preferably serves as the holding section of a scaffolding floor.
- a recess can also be provided on a longitudinal side area of the scaffolding floor as the holding section of the scaffolding floor, in which recess the support section engages in the transverse direction.
- the support section is provided on a carrier extension which protrudes from the stand in the longitudinal direction of the scaffolding floor and has a lateral guide profile which is provided for lateral support of a longitudinal side of a scaffolding floor.
- the carrier extension preferably extends away to a side of the stand remote from the opposite stand, so that there is lateral support for the at least one scaffolding floor at its end region protruding beyond the stand. The carrier extension thus ensures that a perpendicular orientation is maintained between the uprights and the at least one scaffolding floor, so that an oblique alignment of the scaffolding floors in a horizontal plane relative to the uprights and consequently an offset of the uprights relative to one another can be avoided.
- the carrier extension is also provided with the support section for longitudinal support of the at least one scaffolding floor results in a dual function for this functional section of the carrier extension together with the support section.
- the support section provides longitudinal support, ie it prevents the at least one scaffolding deck from slipping in the longitudinal direction. This applies to a lower layer of scaffolding decks. Due to their design and the corresponding stacking, the further scaffolding floors stacked on this lower layer can inevitably interlock in each case in the longitudinal direction, so that a slipping of the upper Scaffolding floors relative to each other is excluded.
- the carrier extensions in connection with the support sections define spacers for symmetric positioning of the scaffolding floors relative to the two uprights, whereby the weight of the scaffolding floors is supported by the uprights evenly distributed. This enables a balanced central lifting of the support frame and the scaffolding decks using a forklift or similar.
- a receiving device for holding at least two stanchions in a non-functional parking position is provided on the stand.
- This configuration is advantageous for the empty transport of the support frame according to the invention. Because the stanchions can be held in the receiving device when not in use, they are captively positioned on the respective stand. At the same time, the overall height of the support frame is reduced as soon as the stanchions are removed from the support feet, so that the stands can be stored and transported in a compact manner.
- the receiving device has a holding structure on the crossbeam and/or on the support feet, into which two stanchions can be inserted in an alignment parallel to the crossbeam.
- the holding structure is preferably formed by pocket sections, which are advantageously designed as a sheet metal construction and are welded to the cross member and/or the support feet.
- the support structure is adapted to the length and cross-sections of the stanchions in order to ensure that the stanchions are well secured in position in the support structure, but at the same time allow easy manual insertion and removal.
- the holding structure is provided on an underside of the cross member. This enables the stanchions to be accommodated in a particularly space-saving manner without impairing a supporting or bearing function of an upper side of the cross member for the scaffolding floors.
- the available space below the cross member and between the two support feet is used to attach the holding structure.
- the receiving device is assigned at least one mechanical securing means, which secures at least one stanchion in the parking position.
- the mechanical securing means can take the form of a cotter pin, a securing bolt, a pivotably mounted securing pawl or something similar, movable between a release position and a securing position relative to the holding structure Be running security component.
- the securing means is preferably operated without tools by being handled by an operator.
- a support frame 1 after 1 and 5 until 7 has two stands 2, which are designed as separate components.
- the two stands 2 are made of sheet steel parts, as will be explained in more detail below.
- the two stand 2 are used to store a variety of scaffolding floors 3, based on the 3 and 4 are shown in more detail.
- the scaffolding decks 3 are common parts of scaffolding and are known to those skilled in the art, so that the scaffolding decks 3 are not described in detail at this point.
- the scaffolding decks 3 are intended to be hung in vertical scaffolding frames when erecting scaffolding. After the scaffolding has been completed, the scaffolding decks form floor surfaces that can be walked on and walked on on the different floors of a scaffolding.
- the two stand 2 according to 1 are identical to each other. Based on Figures 5 to 7 one of the two stands 2 is described in detail below. For the other stand 2 according to 1 what has been said applies in the same way.
- Each stand 2 has two support feet which are connected to one another via a cross member 10 .
- Each support foot has on the one hand a funnel-like widened foot part 6 and on the other hand a support tube 4 .
- Both the foot part 6 and the support tube 4 are square-shaped, with the support tube 4 having a square-shaped receptacle open at the top for the insertion of a square-shaped stanchion 5 in each case.
- Each stanchion 5 forms a square hollow section made of steel with a square cross-section.
- a transverse floor is preferably inserted just above the foot part 6, on which the stanchion 5 is supported in the vertical direction as soon as it is inserted into the receptacle of the support tube 4.
- the two support tubes 4 are firmly connected to one another via the cross member 10 , the cross member 10 having a width which is less than or equal to a width of the respective support tube 4 .
- the cross member 10 is formed by a square profile, which is attached on opposite end faces to an inner side of the respective support tube 4 facing the other support foot. In the exemplary embodiment shown, the connection of corresponding end faces of the cross member 10 to the support tubes 4 takes place by welding.
- Both the cross member 10 and the support tubes 4 and the foot parts 6 are designed as sheet steel constructions and form a one-piece unit.
- each carrier extension 8 is designed as a U-shaped angle profile which - when the stand 2 is standing on horizontal ground - protrudes horizontally and orthogonally both to the support tube 4 and to the cross member 10 from the respective support foot.
- the two carrier extensions 8 on the opposite support feet protrude in the same direction from the support feet and parallel to one another.
- the carrier extensions 8 flank lateral longitudinal edge sections of the scaffolding floors 3 in parallel and thus form lateral supports and guides for the scaffolding floors 3 in order to prevent that the scaffolding floors 3 are aligned obliquely to the two uprights 2 in a horizontal plane.
- the carrier extensions 8 thus ensure that the scaffolding floors 3 are aligned orthogonally to the transversely extending uprights 2, ie at right angles, in the horizontal plane formed by a bearing surface of an upper side of the respective cross member 10.
- the carrier extensions 8 of the stands 2 are positioned at the level of a lower layer of scaffolding floors 3, so that the carrier extensions 8 form a lateral guide and lateral support for the lowest layer of scaffolding floors 3 in each case.
- Each carrier extension 8 is also provided at its free front end with a support section 9 which protrudes horizontally inwards towards the opposite carrier extension 8 and is designed as a support web 9 bent at right angles.
- each support section 9 engages in the transverse direction in a respective suspension hook 11 arranged on the scaffolding deck 3 at the front.
- the hooks 11 When erecting scaffolding, the hooks 11 are used to attach a scaffolding base to a cross member profile of a vertical scaffolding frame of the scaffolding.
- the suspension hooks 11 form groove-like holding sections (hereinafter also receiving grooves) in which the support sections 9 engage in a form-fitting manner in the longitudinal direction of the scaffolding floors 3, such as that 1 can be removed.
- the support sections 9 therefore ensure that the scaffolding floors 3 can no longer be displaced in the longitudinal direction of the coordinate system and thus transversely to the uprights 2 .
- the uprights 2 are positioned so far apart from one another that the supporting sections 9 of the opposite carrier extensions 8 of both uprights 2 can dip into the receiving grooves, ie the holding sections, of the hanging hooks 11 on the opposite end faces of the scaffolding floors 3 .
- the uprights 2 are also aligned in such a way that the support extensions 8 protrude from the support feet toward the sides remote from the respective other upright 2 .
- the scaffolding floors 3 protrude beyond the uprights 2 on both sides as soon as they are placed on the uprights 2 in a secured position.
- the uprights 2 also have a holding device which serves to prevent the scaffolding floors 3 from being able to move relative to the respective upright 2 in the vertical direction.
- a support web 7 is provided on each support foot, which is firmly connected to the support tube 4 and protrudes horizontally to the opposite support foot and thus parallel to the cross member 10 inwards.
- the support web 7 is designed as a U-shaped support plate which is firmly welded to an outer wall of the respective support tube 4 .
- the support web 7 extends in a horizontal plane just above the carrier extension 8 and protrudes orthogonally from the support tube 4 to the outside.
- the support webs 7 of the opposite support feet of a stand 2 are at the same height and consequently at the same distance above a bearing surface of the crossbeam 10 for the scaffolding floors 3 - seen in the vertical direction - positioned.
- the distance in the vertical direction is slightly greater than a thickness of a scaffolding floor 3, so that each support bar 7 engages over the respective scaffolding floor 3 after the scaffolding floor 3 has been placed on the cross member 10 of the respective stand 2 in the vertical direction in a form-fitting manner.
- the length of the respective crossbeam 10 is matched to the width of a scaffolding floor 3 in such a way that the length of the crossbeam 10 between the opposite support feet of the upright 2 corresponds to slightly more than twice the width of a scaffolding floor 3.
- the two uprights 2 are first positioned at a parallel distance from one another on a flat surface.
- a first scaffolding deck 3 is then placed on the bearing surfaces of the two crossbeams 10 of the two uprights 2 and pushed in the transverse direction to one side of the two uprights 2 so far that a longitudinal edge of the scaffolding deck 3 is on the inside of the support tube 4 of the respective upright 2 comes to rest, which inevitably this longitudinal edge is pushed under the respective support bar 7.
- the two uprights 2 are also spaced apart in the longitudinal direction relative to one another in such a way that the support sections 9 of the carrier extensions 8 can dip into the receiving grooves of the suspension hooks 11 on the opposite end faces of the scaffolding floor 3 .
- the second scaffolding deck 3 is then placed in the same way on the remaining free contact surfaces of the crossbeams 10 of the stands 2 and pushed in the transverse direction under the support webs 7 of the support tubes 4 of the opposite support feet of the two stands 2, whereby at the same time the support sections 9 of the opposite beam extensions 8 engage in the receiving grooves of the hooks 11 of this scaffolding floor 3.
- Both scaffolding floors 3 are inserted between the posts 2 with their upper side pointing downwards, so that the receiving grooves of the suspension hooks 11 of the scaffolding floors 3 are open at the top.
- the support sections 9 of the carrier extensions 8 enter these receiving grooves of the suspension hooks 11 from the side and from above.
- further layers of two scaffolding floors 3 are stacked onto this lower layer of scaffolding floors 3 .
- the support frame 1a according to 2 is largely identical to the support frame 1 according to the 1 and 5 until 7 .
- Identical or functionally equivalent components or sections of the support frame 1a and the two uprights 2a are therefore provided with the same reference numbers, but with the addition of a letter a. To avoid repetition with respect to the support frame 1a therefore to the description of the support frame 1 and the two uprights 2 according to 1 and 5 until 7 referred.
- the only difference in the support frame 1a is that the length of the crossbeams 10a of the two uprights 2a is matched to three times the width of a scaffolding floor 3 .
- the central stack of scaffolding decks 3 between the lateral stacks of scaffolding decks 3 facing the respective support feet of the uprights 2a is not supported in a form-fitting manner in the longitudinal direction by corresponding support sections 9a of the carrier extensions 8a.
- Lateral support and guidance by the carrier extensions 8a is also not necessarily provided for this central stack of scaffolding floors 3. Rather, the lateral support is taken over by the respective laterally flanking outer stacks of scaffold decks 3 .
- Both the uprights 2 and the uprights 2a have foot sections 6a that are widened in a funnel shape and open at the bottom in the region of the opposite supporting feet. These are intended to support stacking of stands on top of each other.
- the foot sections 6a can be placed in the area of their underside both - after removal of the stanchions 5 - on the tops of the support tubes 4, 4a of the respective underlying stand 2 and - with inserted stanchions 5, 5a - on the upper edges of the stanchions 5 of the underlying stand 2 , 2a are stacked. It is thus possible to stack several supporting frames 1, 1a on top of one another with corresponding scaffolding floor stacks.
- a forklift truck can or another transport device gripping the lower layer of scaffolding decks 3 between the two uprights 2, 2a and thus lifting and moving the entire support frame 1, 1a including the scaffolding decks 3 stacked between the uprights 2, 2a.
- the holding device is designed in such a way that a stable lifting of the uprights 2, 2a and the lower layer of scaffolding decks 3 is ensured even without scaffolding decks lying above them.
- the stanchions 5 are arranged on the respective support foot of the stand 2 so that they can be detached without tools.
- the stanchions 5 are simply inserted into the receptacles of the support tubes 4, as has already been explained.
- a holding structure 12 is provided below each cross member 10 and serves as a receiving device for the two stanchions 5 of the stand 2 .
- the holding structure 12 has two spaced-apart receiving pockets (also referred to as pocket sections) on the underside of the cross member 10 .
- the receiving pockets 12 are welded to the underside of the cross member 10 and designed in such a way that the two stanchions 5 designed as square tubes can be inserted between the receiving pockets and pushed in.
- a width of each receiving pocket 12 is designed in such a way that the two stanchions 5 can be placed side by side in the holding structure 12 .
- The is based on the 6 and 7 left receiving pocket of the holding structure 12 designed in such a way that it has a rectangular receiving opening with approximately the height of a side length of a stanchion 5 and approximately twice the width of a side length of a stanchion 5 .
- the receiving pocket is closed in the vertical upward direction.
- the opposite receiving pocket has the same width, but is open at the top on a side pointing forwards over a front side of the cross member 10 .
- the first stanchion is first inserted obliquely from above and from the side into the left receiving pocket of the holding structure 12 and then placed from above into the open area of the right receiving pocket 12.
- the stanchion 5 is then pushed backwards under the cross member 10 in the longitudinal direction of the coordinate system.
- the second stanchion 5 is first inserted in the same way into the left receiving pocket and then placed over the open side of the right receiving pocket.
- a securing means 14 is provided.
- the securing means 14 is designed as a cotter pin which can be inserted into a bore 13 in a side wall of the right-hand receiving pocket 12 .
- the securing means 14 can also be removed again manually and without tools after the manual, tool-free insertion in a correspondingly reverse manner as soon as the stanchions 5 are required again.
- the support structure 12 is a section of the one-piece structural unit of the stand 2, which consists of the cross member 10, the lateral support feet, the support extension 8 in the area of each support foot and the support web 7 is formed in the area of each support leg. All parts and sections of this assembly are designed as sheet steel constructions and are connected to one another in one piece by welding.

Diese Aufgabe wird mit den Merkmalen der unabhängigen Ansprüche 1 und 10 gelöst. Dabei wird bei dem Trägergestell nach Anspruch 10 eine in Hochrichtung formschlüssig wirksame Halteeinrichtung für wenigstens einen Gerüstboden vorgesehen, die dem Ständer zugeordnet ist. Die Halteeinrichtung gewährleistet, dass bei einem Anheben des wenigstens einen Gerüstbodens der wenigstens eine Ständer mit angehoben wird, so dass das Trägergestell einschließlich des wenigstens einen Gerüstbodens durch einen Gabelstapler oder ein ähnliches Transportgerät angehoben und verfahren werden kann. Die Halteeinrichtung gewährleistet, dass beim Untergreifen eines entsprechenden Gerüstbodens oder eines entsprechenden Gerüstbodenstapels, der in dem Trägergestell angeordnet ist, die entsprechende Hubkraft über die Halteeinrichtung auf den wenigstens einen Ständer übertragen wird. Die erfindungsgemäße Lösung eignet sich für die Lagerung und den Transport von Gerüstböden, die bei Baugerüsten eingesetzt werden, und die entsprechend begehbare Bodenflächen eines Baugerüsts im jeweiligen Gerüststockwerk bilden. Die erfindungsgemäße Lösung ermöglicht eine sichere Stapelung einer Vielzahl von Gerüstböden, die auch bei längerer Lagerung eine exakte Stapelform beibehalten und so zuverlässig die Gefahr eines Umfallens des Gerüstbodenstapels vermeiden. Erfindungsgemäß sind zwei Ständer als voneinander getrennte Bauteile vorgesehen, die in funktionsfertigem Zustand zueinander parallel beabstandet sind und in Hochrichtung ausgerichtet sind. Entsprechende Gerüstböden, die zwischen den beiden Ständern erstreckt sind, bilden eine Querverbindung zwischen den beiden Ständern. Aufgrund der formschlüssigen Sicherung mittels der Halteeinrichtung bilden die beiden Ständer sowie mehrere Gerüstböden eine gemeinsam handhabbare Transport- und Lagereinheit. In besonders vorteilhafter Weise sind die beiden als voneinander getrennte Bauteile gestalteten Ständer baugleich zueinander gestaltet. Unter den Begriff der Baugleichheit fällt zum einen eine identische Gestaltung der Ständer, zum anderen aber auch eine funktionsgleiche Gestaltung der Ständer mit spiegelsymmetrisch angeordneten, im Übrigen aber identischen Funktionsabschnitten. Die erfindungsgemäße Lösung eignet sich sowohl für zueinander identische als auch für unterschiedlich gestaltete Gerüstböden mit gleichen oder unterschiedlichen Breiten.This object is solved with the features of
Das erfindungsgemäße Trägergestell ist vorzugsweise aus Metallteilen, insbesondere aus Stahlteilen, als Stahlblechkonstruktion gestaltet, wobei entsprechend fest miteinander verbundene Funktionsteile und Funktionsabschnitte vorzugsweise miteinander verschweißt sind. Statt einer Stahlblechkonstruktion kann das erfindungsgemäße Trägergestell auch aus Leichtmetallbauteilen hergestellt sein. Die Rungen sind vorzugsweise als Vierkantrohre gestaltet, sie können aber in gleicher Weise auch als Hohl- oder Vollprofile mit anderen rotationssymmetrischen oder rotationsunsymmetrischen Querschnitten gestaltet sein. Entsprechende Aufnahmen der Stützfüße zur werkzeuglosen Montage der Rungen sind derart auf Profilquerschnitte der Rungen abgestimmt, dass sich eine Steckverbindung zwischen den Rungen und den entsprechenden Aufnahmen der Stützfüße ergibt. Vorzugsweise sind die Rungen in die Aufnahmen eingesteckt. Alternativ können die Rungen als Hohlprofile auch auf als Steckzapfen ausgeführte Aufnahmen der Stützfüße außenseitig aufgesteckt werden.The support frame according to the invention is preferably made of metal parts, in particular steel parts, designed as a sheet steel construction, functional parts and functional sections that are correspondingly firmly connected to one another preferably being welded to one another. Instead of a sheet steel construction, the support frame according to the invention can also be made from light metal components. The stanchions are preferably designed as square tubes, but they can also be designed in the same way as hollow or solid profiles with other rotationally symmetrical or rotationally asymmetrical cross sections. Corresponding mounts of the support feet for tool-free assembly of the stanchions are matched to the profile cross-sections of the stanchions in such a way that there is a plug-in connection between the stanchions and the corresponding mounts of the support feet. The stanchions are preferably inserted into the receptacles. Alternatively, the stanchions, as hollow profiles, can also be attached to the outside of the support feet, which are designed as plug-in pins.
Erfindungsgemäß ist dem Ständer eine Längsstützeinrichtung zur formschlüssigen Stützung wenigstens eines Gerüstbodens in Längsrichtung zugeordnet. Jeder der Ständer weist jeweils eine Längsstützeinrichtung auf. Die jeweilige Längsstützeinrichtung dient bei zwei Ständern als Abstandshalter zur symmetrischen Positionierung der Ständer in Längsrichtung relativ zu den Gerüstböden. Dies ermöglicht eine gleichmäßige Gewichtsverteilung. Denn die entsprechende Ausgestaltung dient dazu, ein Verrutschen in Längsrichtung des wenigstens einen unteren Gerüstbodens, der auf entsprechenden Querträgern der Ständer aufliegt, zu vermeiden. Falls die Länge des Querträgers zwischen den Stützfüßen jedes Ständers so bemessen ist, dass zwei Gerüstböden in einer Lage zwischen den Stützfüßen jedes Ständers positioniert werden können, dann weist die Längsstützeinrichtung eine Längsstützfunktion für jeden dieser Gerüstböden der untersten Lage auf.According to the invention, a longitudinal support device for form-fitting support of at least one scaffolding deck in the longitudinal direction is assigned to the stand. Each of the stands each has a longitudinal support device. In the case of two uprights, the respective longitudinal support device serves as a spacer for the symmetrical positioning of the uprights in the longitudinal direction relative to the scaffolding floors. This allows for an even weight distribution. This is because the corresponding configuration serves to prevent the at least one lower scaffolding floor, which rests on corresponding crossbeams of the stand, from slipping in the longitudinal direction. If the length of the cross member between the support legs of each upright is such that two scaffolding floors can be positioned in one tier between the support legs of each upright, then the longitudinal support means has a longitudinal support function for each of those scaffolding floors of the lowest tier.
Erfindungsgemäß weist der Querträger eine Länge auf, die zumindest weitgehend einem ganzzahligen Vielfachen einer Breite eines Gerüstbodens oder eines Stapels von wenigstens zwei übereinander gestapelten Gerüstböden entspricht. Vorzugsweise ist unter dem ganzzahligen Vielfachen die Zahl 2 oder die Zahl 3 zu verstehen, so dass die Ausgestaltung die Nebeneinanderpositionierung von zwei oder drei Gerüstböden in einer horizontalen Lage auf den Querträgern der beiden zueinander beabstandeten Ständer ermöglicht. Der Abstand zwischen den beiden Stützfüßen jedes Ständers, der zumindest weitgehend die Länge des entsprechenden Querträgers des Ständers definiert, ist vorteilhaft geringfügig größer als das ganzzahlige Vielfache der Breite eines Gerüstbodens, um Verklemmungen der Gerüstböden beim Aufsetzen oder Entnehmen zu vermeiden.According to the invention, the cross member has a length which at least largely corresponds to an integer multiple of a width of a scaffolding deck or a stack of at least two scaffolding decks stacked on top of one another. Preferably, the integer multiple is the
Erfindungsgemäss weist die Halteeinrichtung jeweils einen radial von dem einen Stützfuß zu dem gegenüberliegenden Stützfuß des Ständers hin abragenden Stützsteg auf, der in Hochrichtung in einem Abstand zu dem Querträger angeordnet ist, der einer Dicke eines Gerüstbodens oder eines Stapels von wenigstens zwei übereinandergestapelten Gerüstböden entspricht. Somit ist jeder Stützfuß mit einem zum gegenüberliegenden Stützfuß hin abragenden Stützsteg versehen. Falls der Ständer auf einem Untergrund in Hochrichtung, d.h. vertikal, ausgerichtet ist, erstreckt sich der Stützsteg horizontal von einer Innenseite des einen Stützfußes zu dem gegenüberliegenden Stützfuß des Ständers, so dass die beiden Stützstege eines Ständers einander zugewandt sind. Beide Stützstege sind in gleichem Abstand zu einer Oberseite des Querträgers des Ständers positioniert. Der Abstand zu dem Querträger für den jeweiligen Stützsteg ist so gewählt, dass ein Gerüstboden bzw. zwei oder drei Gerüstböden in einer gemeinsamen, nebeneinander positionierten Horizontallage auf demAccording to the invention, the holding device has in each case a support web which protrudes radially from one support foot to the opposite support foot of the stand and which is arranged in the vertical direction at a distance from the cross member which corresponds to the thickness of a scaffolding deck or a stack of at least two scaffolding decks stacked on top of one another. Thus, each support leg is provided with a support web that protrudes toward the opposite support leg. If the stand is aligned vertically, ie vertically, on a base, the support bar extends horizontally from an inside of one support foot to the opposite support foot of the stand, so that the two support bars of a stand face each other. Both support webs are positioned at the same distance from a top of the cross member of the stand. The distance to the cross member for each support bar is chosen so that a scaffolding or two or three scaffolding floors in a common horizontal position next to each other on the
Querträger abgelegt werden können, wobei jeweils außenliegende Längsrandbereiche der an den Stützfüßen anliegenden Gerüstbodenabschnitte den jeweiligen Stützsteg untergreifen.Crossbeams can be stored, with the respective outer longitudinal edge regions of the scaffolding floor sections resting against the support feet reaching under the respective support web.
Alternativ kann der jeweilige Stützsteg auch in größerem Abstand zu dem Querträger am Stützfuß befestigt sein, so dass ein Stapel von zwei oder mehr übereinandergestapelten Gerüstböden zwischen den Querträger und den entsprechenden Stützsteg des Stützfußes eingefügt werden kann.Alternatively, the respective support web can also be attached to the support foot at a greater distance from the cross member, so that a stack of two or more scaffolding decks stacked on top of one another can be inserted between the cross member and the corresponding support web of the support foot.
Erfindungsgemäß weist die Längsstützeinrichtung wenigstens einen an dem Ständer befestigten Stützabschnitt auf, der in Querrichtung und/oder in Hochrichtung erstreckt ist, um einen Halteabschnitt eines Gerüstbodens in Längsrichtung des Gerüstbodens zu hintergreifen. Der Stützabschnitt ragt demzufolge derart in einen Halteabschnitt eines Gerüstbodens hinein, dass sich ein Formschluss in Längsrichtung des Gerüstbodens ergibt, so dass ein Verrutschen des Gerüstbodens orthogonal zur Längsrichtung der Querträger der Ständer vermieden wird. Der Stützabschnitt ist als Metalllasche oder als Metallsteg gestaltet, der fest mit einem Stützfuß oder mit dem Querträger des jeweiligen Ständers verbunden, vorzugsweise mit dem entsprechenden Bauteil verschweißt ist. Als Halteabschnitt eines Gerüstbodens dient vorzugsweise ein Hinterschnitt oder eine Aufnahmenut eines stirnseitig an dem Gerüstboden vorgesehenen Einhängehakens. Alternativ kann als Halteabschnitt des Gerüstbodens auch eine Ausnehmung an einem Längsseitenbereich des Gerüstbodens vorgesehen sein, in den der Stützabschnitt in Querrichtung eingreift.According to the invention, the longitudinal support device has at least one support section fastened to the post, which extends in the transverse direction and/or in the vertical direction in order to engage behind a holding section of a scaffolding floor in the longitudinal direction of the scaffolding floor. The support section therefore protrudes into a holding section of a scaffolding floor in such a way that there is a form fit in the longitudinal direction of the scaffolding floor, so that the scaffolding floor is prevented from slipping orthogonally to the longitudinal direction of the crossbeams of the uprights. The support section is designed as a metal bracket or as a metal web that is firmly connected to a support foot or to the cross member of the respective stand, preferably welded to the corresponding component. An undercut or a receiving groove of a suspension hook provided on the end face of the scaffolding floor preferably serves as the holding section of a scaffolding floor. Alternatively, a recess can also be provided on a longitudinal side area of the scaffolding floor as the holding section of the scaffolding floor, in which recess the support section engages in the transverse direction.
In weiterer Ausgestaltung der Erfindung ist der Stützabschnitt an einem von dem Ständer in Längsrichtung des Gerüstbodens abragenden Trägerfortsatz vorgesehen, der ein Seitenführungsprofil aufweist, das zur seitlichen Stützung einer Längsseite eines Gerüstbodens vorgesehen ist. Der Trägerfortsatz erstreckt sich vorzugsweise zu einer von dem gegenüberliegenden Ständer abliegenden Seite des Ständers weg, so dass sich für den wenigstens einen Gerüstboden an seinem über den Ständer hinausragenden Endbereich eine Seitenstützung ergibt. Der Trägerfortsatz gewährleistet so die Aufrechterhaltung einer rechtwinkligen Ausrichtung zwischen den Ständern und dem wenigstens einen Gerüstboden, so dass eine Schrägausrichtung der Gerüstböden in einer Horizontalebene relativ zu den Ständern und demzufolge ein Versatz der Ständer relativ zueinander vermieden werden können. Dadurch, dass der Trägerfortsatz auch noch mit dem Stützabschnitt zur Längsstützung des wenigstens einen Gerüstbodens versehen ist, ergibt sich für diesen Funktionsabschnitt des Trägerfortsatzes zusammen mit dem Stützabschnitt eine Doppelfunktion. Denn neben der Seitenstützung durch den Trägerfortsatz bildet der Stützabschnitt die Längsstützung, d.h. die Vermeidung eines Verrutschens des wenigstens einen Gerüstbodens in Längsrichtung. Dies gilt jeweils für eine untere Lage von Gerüstböden. Die auf diese untere Lage gestapelten weiteren Gerüstböden können aufgrund ihrer Gestaltung und der entsprechenden Stapelung zwangsläufig in Längsrichtung jeweils ineinandergreifen, so dass ein Verrutschen der oberen Gerüstböden relativ zueinander ausgeschlossen ist. Bei zwei Ständern mit Trägerfortsätzen und zugeordneten Stützabschnitten definieren die Trägerfortsätze in Verbindung mit den Stützabschnitten Abstandshalter zur symmetrischen Positionierung der Gerüstböden relativ zu den zwei Ständern, wodurch die Gerüstböden in ihrer Gewichtskraft gleichmäßig verteilt von den Ständern gestützt werden. Dies ermöglicht ein ausgewogenes mittiges Anheben des Trägergestells und der Gerüstböden durch einen Gabelstapler oder ähnlichem.In a further embodiment of the invention, the support section is provided on a carrier extension which protrudes from the stand in the longitudinal direction of the scaffolding floor and has a lateral guide profile which is provided for lateral support of a longitudinal side of a scaffolding floor. The carrier extension preferably extends away to a side of the stand remote from the opposite stand, so that there is lateral support for the at least one scaffolding floor at its end region protruding beyond the stand. The carrier extension thus ensures that a perpendicular orientation is maintained between the uprights and the at least one scaffolding floor, so that an oblique alignment of the scaffolding floors in a horizontal plane relative to the uprights and consequently an offset of the uprights relative to one another can be avoided. The fact that the carrier extension is also provided with the support section for longitudinal support of the at least one scaffolding floor results in a dual function for this functional section of the carrier extension together with the support section. In addition to the lateral support provided by the carrier extension, the support section provides longitudinal support, ie it prevents the at least one scaffolding deck from slipping in the longitudinal direction. This applies to a lower layer of scaffolding decks. Due to their design and the corresponding stacking, the further scaffolding floors stacked on this lower layer can inevitably interlock in each case in the longitudinal direction, so that a slipping of the upper Scaffolding floors relative to each other is excluded. With two uprights with carrier extensions and associated support sections, the carrier extensions in connection with the support sections define spacers for symmetric positioning of the scaffolding floors relative to the two uprights, whereby the weight of the scaffolding floors is supported by the uprights evenly distributed. This enables a balanced central lifting of the support frame and the scaffolding decks using a forklift or similar.
In weiterer Ausgestaltung der Erfindung ist an dem Ständer eine Aufnahmeeinrichtung zur Halterung von wenigstens zwei Rungen in einer funktionslosen Parkstellung vorgesehen. Diese Ausgestaltung ist für den Leertransport des erfindungsgemäßen Trägergestells vorteilhaft. Denn dadurch, dass die Rungen bei Nichtbenutzung in der Aufnahmeeinrichtung gehaltert werden können, sind sie verliersicher an dem jeweiligen Ständer positioniert. Gleichzeitig reduziert sich eine Bauhöhe des Trägergestells, sobald die Rungen aus den Stützfüßen entfernt sind, so dass die Ständer kompakt abgelegt und transportiert werden können.In a further embodiment of the invention, a receiving device for holding at least two stanchions in a non-functional parking position is provided on the stand. This configuration is advantageous for the empty transport of the support frame according to the invention. Because the stanchions can be held in the receiving device when not in use, they are captively positioned on the respective stand. At the same time, the overall height of the support frame is reduced as soon as the stanchions are removed from the support feet, so that the stands can be stored and transported in a compact manner.
In weiterer Ausgestaltung der Erfindung weist die Aufnahmeeinrichtung eine Haltestruktur an dem Querträger und/oder an den Stützfüßen auf, in die zwei Rungen in zu dem Querträger paralleler Ausrichtung einsetzbar sind. Die Haltestruktur wird vorzugsweise durch Taschenabschnitte gebildet, die vorteilhaft als Metallblechkonstruktion gestaltet und mit dem Querträger und/oder den Stützfüßen verschweißt sind. Die Haltestruktur ist an Länge und Querschnitte der Rungen angepasst, um eine gute Positionssicherung der Rungen in der Haltestruktur, gleichzeitig aber dennoch ein einfaches manuelles Einlegen und Entnehmen zu ermöglichen.In a further embodiment of the invention, the receiving device has a holding structure on the crossbeam and/or on the support feet, into which two stanchions can be inserted in an alignment parallel to the crossbeam. The holding structure is preferably formed by pocket sections, which are advantageously designed as a sheet metal construction and are welded to the cross member and/or the support feet. The support structure is adapted to the length and cross-sections of the stanchions in order to ensure that the stanchions are well secured in position in the support structure, but at the same time allow easy manual insertion and removal.
In weiterer Ausgestaltung der Erfindung ist die Haltestruktur an einer Unterseite des Querträgers vorgesehen. Dies ermöglicht eine besonders platzsparende Unterbringung der Rungen, ohne dass eine Stütz- oder Auflagefunktion einer Oberseite des Querträgers für die Gerüstböden beeinträchtigt wird. In vorteilhafter Weise wird zur Anbringung der Haltestruktur der zur Verfügung stehende Raum unterhalb des Querträgers und zwischen den beiden Stützfüßen verwendet.In a further embodiment of the invention, the holding structure is provided on an underside of the cross member. This enables the stanchions to be accommodated in a particularly space-saving manner without impairing a supporting or bearing function of an upper side of the cross member for the scaffolding floors. Advantageously, the available space below the cross member and between the two support feet is used to attach the holding structure.
In weiterer Ausgestaltung der Erfindung ist der Aufnahmeeinrichtung wenigstens ein mechanisches Sicherungsmittel zugeordnet, das wenigstens eine Runge in der Parkstellung sichert. Das mechanische Sicherungsmittel kann als Sicherungssplint, als Sicherungsbolzen, als schwenkbeweglich gelagerte Sicherungsklinke oder als ähnliches, zwischen einer Freigabestellung und einer Sicherungsstellung relativ zu der Haltestruktur bewegliches Sicherungsbauteil ausgeführt sein. Die Bedienung des Sicherungsmittels erfolgt vorzugsweise werkzeuglos durch Handhabung mittels einer Bedienperson.In a further embodiment of the invention, the receiving device is assigned at least one mechanical securing means, which secures at least one stanchion in the parking position. The mechanical securing means can take the form of a cotter pin, a securing bolt, a pivotably mounted securing pawl or something similar, movable between a release position and a securing position relative to the holding structure Be running security component. The securing means is preferably operated without tools by being handled by an operator.

Ein Trägergestell 1 nach den
Die beiden Ständer 2 gemäß
Jeder Ständer 2 weist zwei Stützfüße auf, die über einen Querträger 10 miteinander verbunden sind. Jeder Stützfuß weist zum einen ein trichterartig aufgeweitetes Fußteil 6 und zum anderen ein Stützrohr 4 auf. Sowohl der Fußteil 6 als auch das Stützrohr 4 sind vierkantförmig ausgeführt, wobei das Stützrohr 4 eine nach oben offene, vierkantförmige Aufnahme für das Einstecken jeweils einer vierkantförmigen Runge 5 aufweist. Jede Runge 5 bildet ein Vierkanthohlprofil aus Stahl mit einem quadratischen Querschnitt. In dem Stützrohr 4 ist vorzugsweise knapp oberhalb des Fußteils 6 ein Querboden eingezogen, auf dem sich die Runge 5 in Hochrichtung abstützt, sobald sie in die Aufnahme des Stützrohrs 4 eingesteckt ist. Die beiden Stützrohre 4 sind über den Querträger 10 fest miteinander verbunden, wobei der Querträger 10 eine Breite aufweist, die geringer oder gleich einer Breite des jeweiligen Stützrohrs 4 ist. Der Querträger 10 wird durch ein Vierkantprofil gebildet, das auf gegenüberliegenden Stirnseiten an jeweils eine dem anderen Stützfuß zugewandte Innenseite des jeweiligen Stützrohrs 4 angefügt ist. Beim dargestellten Ausführungsbeispiel erfolgt die Verbindung entsprechender Stirnflächen des Querträgers 10 mit den Stützrohren 4 durch Verschweißung. Sowohl der Querträger 10 als auch die Stützrohre 4 und die Fußteile 6 sind als Stahlblechkonstruktionen gestaltet und bilden eine einteilige Baueinheit.Each
Ebenfalls einteilig an dem Ständer 2 angebracht sind zwei Trägerfortsätze 8, die rechtwinklig an jeweils eine Vorderseite des jeweiligen Stützrohrs 4 oberhalb des Querträgers 10 angeschweißt sind. Jeder Trägerfortsatz 8 ist als U-artiges Winkelprofil gestaltet, das - in auf horizontalem Untergrund aufstehendem Ständer 2 - horizontal und orthogonal sowohl zu dem Stützrohr 4 als auch zu dem Querträger 10 von dem jeweiligen Stützfuß abragt. Die beiden Trägerfortsätze 8 an den gegenüberliegenden Stützfüßen ragen gleichgerichtet von den Stützfüßen und parallel zueinander ab. Bei funktionsgerechter Positionierung des Ständers 2 auf einem horizontalen Untergrund erstreckt sich der Querträger 10 in Querrichtung eines Koordinatensystems des Trägergestells, die beiden Stützrohe 4 und die Rungen 5 erstrecken sich in Hochrichtung und die beiden Trägerfortsätze 8 erstrecken sich in Längsrichtung dieses Koordinatensystems. Wie anhand der
Die Trägerfortsätze 8 flankieren seitliche Längsrandabschnitte der Gerüstböden 3 parallel und bilden somit seitliche Stützungen und Führungen für die Gerüstböden 3, um zu verhindern, dass die Gerüstböden 3 in einer Horizontalebene schräg zu den beiden Ständern 2 ausgerichtet werden. Die Trägerfortsätze 8 gewährleisten somit, dass die Gerüstböden 3 in der durch eine Auflagefläche einer Oberseite des jeweiligen Querträgers 10 gebildeten Horizontalebene orthogonal zu den quer erstreckten Ständern 2, d.h. rechtwinklig, ausgerichtet werden. Anhand der
Jeder Trägerfortsatz 8 ist an seinem freien Stirnende zudem mit einem zu dem gegenüberliegenden Trägerfortsatz 8 in horizontal nach innen abragenden Stützabschnitt 9 versehen, der als rechtwinklig abgekröpfter Stützsteg 9 ausgeführt ist. Jeder Stützabschnitt 9 greift nach dem Einlegen eines entsprechenden Gerüstbodens 3 in Querrichtung in jeweils einen stirnseitig an dem Gerüstboden 3 angeordneten Einhängehaken 11 ein. Die Einhängehaken 11 dienen beim Aufbau eines Baugerüsts dazu, einen Gerüstboden auf einem Querträgerprofil eines vertikalen Gerüstrahmens des Baugerüsts aufzustecken. Die Einhängehaken 11 bilden nutartige Halteabschnitte (nachfolgend auch Aufnahmenuten), in die die Stützabschnitte 9 in Längsrichtung der Gerüstböden 3 formschlüssig eingreifen, wie der
Die Ständer 2 weisen zudem eine Halteeinrichtung auf, die dazu dient, eine Relativbeweglichkeit der Gerüstböden 3 in Hochrichtung relativ zu dem jeweiligen Ständer 2 zu vermeiden. Hierzu ist an jedem Stützfuß jeweils ein Stützsteg 7 vorgesehen, der fest mit dem Stützrohr 4 verbunden ist und horizontal zum gegenüberliegenden Stützfuß und damit parallel zu dem Querträger 10 nach innen abragt. Beim dargestellten Ausführungsbeispiel ist der Stützsteg 7 als U-artige Stützplatte ausgeführt, die fest mit einer Außenwandung des jeweiligen Stützrohrs 4 verschweißt ist. Der Stützsteg 7 erstreckt sich in einer Horizontalebene knapp oberhalb des Trägerfortsatzes 8 und ragt orthogonal vom dem Stützrohr 4 aus nach außen ab. Die Stützstege 7 der gegenüberliegenden Stützfüße eines Ständers 2 sind auf gleicher Höhe und demzufolge in gleichem Abstand oberhalb einer Auflagefläche des Querträgers 10 für die Gerüstböden 3 - in Hochrichtung gesehen - positioniert. Der Abstand in Hochrichtung ist geringfügig größer als eine Dicke eines Gerüstbodens 3, so dass jeder Stützsteg 7 den jeweiligen Gerüstboden 3 nach dem Auflegen des Gerüstbodens 3 auf den Querträger 10 des jeweiligen Ständers 2 in Hochrichtung formschlüssig übergreift.The
Bei den Ständern 2 ist eine Länge des jeweiligen Querträgers 10 auf eine Breite eines Gerüstbodens 3 derart abgestimmt, dass die Länge des Querträgers 10 zwischen den gegenüberliegenden Stützfüßen des Ständers 2 geringfügig mehr als dem Zweifachen der Breite eines Gerüstbodens 3 entspricht.In the
Für ein Ablegen von Gerüstböden 3 in dem Trägergestell 1 werden zunächst die beiden Ständer 2 in einem parallelen Abstand zueinander auf einem ebenen Untergrund positioniert. Anschließend wird ein erster Gerüstböden 3 auf die Auflageflächen der beiden Querträger 10 der beiden Ständer 2 aufgelegt und in Querrichtung so weit zu der einen Seite der beiden Ständer 2 hin verschoben, dass ein Längsrand des Gerüstbodens 3 an der Innenseite des Stützrohrs 4 des jeweiligen Ständers 2 zur Anlage kommt, wodurch zwangsläufig dieser Längsrand unter den jeweiligen Stützsteg 7 geschoben wird. Die beiden Ständer 2 sind zudem derart relativ zueinander in Längsrichtung beabstandet, dass die Stützabschnitte 9 der Trägerfortsätze 8 jeweils stirnseitig in die Aufnahmenuten der Einhängehaken 11 der gegenüberliegenden Stirnseiten des Gerüstbodens 3 eintauchen können. Anschließend wird der zweite Gerüstboden 3 in gleicher Weise auf den verbleibenden freien Auflageflächen der Querträger 10 der Ständer 2 aufgelegt und in Querrichtung unter die Stützstege 7 der Stützrohre 4 der gegenüberliegenden Stützfüße der beiden Ständer 2 geschoben, wobei gleichzeitig auch die Stützabschnitte 9 der gegenüberliegenden Trägerfortsätze 8 in die Aufnahmenuten der Einhängehaken 11 dieses Gerüstbodens 3 eingreifen. Beide Gerüstböden 3 werden mit ihrer Oberseite nach unten gerichtet zwischen die Ständer 2 eingefügt, so dass die Aufnahmenuten der Einhängehaken 11 der Gerüstböden 3 nach oben hin offen sind. In entsprechender Weise tauchen die Stützabschnitte 9 der Trägerfortsätze 8 von der Seite und von oben her in diese Aufnahmenuten der Einhängehaken 11 ein. In nicht näher dargestellter Weise werden weitere Lagen von jeweils zwei Gerüstböden 3 auf diese untere Lage von Gerüstböden 3 aufgestapelt.For storing
Das Trägergestell 1a gemäß
Einziger Unterschied bei dem Trägergestell 1a ist es, dass die Querträger 10a der beiden Ständer 2a in ihrer Länge auf eine dreifache Breite eines Gerüstbodens 3 abgestimmt sind. Somit ergeben sich, wie anhand der
Sowohl die Ständer 2 als auch die Ständer 2a weisen trichterförmig aufgeweitete und nach unten offene Fußabschnitte 6a im Bereich der gegenüberliegenden Stützfüße auf. Diese sind dazu vorgesehen, ein Aufeinanderstapeln von Ständern aufeinander zu unterstützen. Dabei können die Fußabschnitte 6a im Bereich ihrer Unterseite sowohl - nach Entnahme der Rungen 5 - auf die Oberseiten der Stützrohre 4, 4a des jeweils darunterliegenden Ständers 2 als auch - bei eingesteckten Rungen 5, 5a - auf die Oberkanten der Rungen 5 des darunterliegenden Ständers 2, 2a aufgestapelt werden. So ist es möglich, mehrere Trägergestelle 1, 1a mit entsprechenden Gerüstbodenstapeln aufeinanderzustapeln.Both the
Dadurch, dass die jeweils untere Lage von Gerüstböden 3 über die als Halteeinrichtung dienenden Stützstege 7 in Hochrichtung formschlüssig an den Ständern 2, 2a abgestützt ist und die darüberliegenden Lagen von aufgestapelten Gerüstböden 3 aufgrund ihrer Gewichtskraft diese untere Lage von Gerüstböden 3 stützen, kann ein Gabelstapler oder ein anderes Transportgerät die untere Lage von Gerüstböden 3 zwischen den beiden Ständern 2, 2a untergreifen und so das gesamte Trägergestell 1, 1a einschließlich der zwischen den Ständern 2, 2a gestapelten Gerüstböden 3 anheben und verfahren. Dies ermöglicht entweder ein einfaches Be- und Entladen der Gerüstböden 3 relativ zu einer Ladefläche eines Lastkraftwagens oder relativ zu einem stationären Lagerort eines entsprechenden Geländes einer Immobilie. Die Halteeinrichtung ist im Übrigen derart ausgeführt, dass ein stabiles Anheben der Ständer 2, 2a und der unteren Lage von Gerüstböden 3 auch ohne darüber liegende Gerüstböden gewährleistet ist.Because the respective lower layer of
Um bei Nichtbenutzung der Ständer 2 kompakte Abmessungen zu ermöglichen, die eine Lagerung oder einen Leertransport vereinfachen, sind die Rungen 5 an dem jeweiligen Stützfuß des Ständers 2 werkzeuglos lösbar angeordnet. Bei dem dargestellten Ausführungsbeispiel sind die Rungen 5 in einfacher Weise in die Aufnahmen der Stützrohre 4 eingesteckt, wie zuvor bereits ausgeführt wurde. Unterhalb jedes Querträgers 10 ist eine Haltestruktur 12 vorgesehen, die als Aufnahmeeinrichtung für die beiden Rungen 5 des Ständers 2 dient. Hierzu weist die Haltestruktur 12 zwei zueinander beabstandete Aufnahmetaschen (auch als Taschenabschnitte bezeichnet) an der Unterseite des Querträgers 10 auf. Die Aufnahmetaschen 12 sind an die Unterseite des Querträgers 10 angeschweißt und derart gestaltet, dass die beiden als Vierkantrohre gestalteten Rungen 5 zwischen die Aufnahmetaschen eingelegt und eingeschoben werden können. Eine Breite jeder Aufnahmetasche 12 ist derart ausgeführt, dass die beiden Rungen 5 nebeneinander in der Haltestruktur 12 abgelegt werden können. Dabei ist die anhand der
