Definitions

  • the invention relates to a Gerüstrastêt as tread in scaffolding consisting of at least two elongated, plate-shaped profiles, which are fastened in each case with a first longitudinal side on the second longitudinal side of the adjacent profile, each profile has at its first longitudinal side at least one outstanding connecting element and in the second longitudinal side is introduced an equal or larger number of projecting into the profile connecting elements and the connecting elements of both longitudinal sides are at least partially complementary formed and at least one pair of corresponding connecting elements of two adjacent profiles is a latching connection.
  • one of the oldest principles is to assemble the scaffolding floors from several parallel oriented boards that have been cut out of tree trunks.
  • An example of this is the DE 38 08 100 with a scaffold floor of three solid wood board strips glued to a block.
  • the disadvantage is that such a scaffold floor in comparison to wooden floors or treads made of aluminum is relatively weighty and that the manufacturing process requires comparatively complex and large plate bending machines.
  • a limitation may also be that a corrosion protection layer cracks in the area of the bends or even flakes off.
  • scaffold floors made of aluminum are also known on the current state of the art. Since simple plates provide sufficient carrying capacity only with enormous material thickness, it is known to reinforce a relatively thin, horizontal aluminum surface on its underside by vertical ribs, such. B. the DE 94 137 22.6 shows. The ribs are stressed especially at their lowest edge very strong and on train. That's why it shows DE 94 137 22.6 a T-shaped widening of the lower edge of each rib, whereby the ratio between the total weight of the individual scaffolding floor profile and its maximum load capacity is significantly improved.
  • the scaffold floor according to EP 0686 739 consists of several, parallel hollow sections. These parallel profiles must be connected together during assembly. And not only so that the profiles do not fall apart during assembly, but above all, so that a punctual load of a single profile - such. B. from a shoe of a person on it - not only by the directly touched profile but also by the adjacent profiles is worn.
  • connection technology is mainly used in the automotive industry because automobiles are exposed for a considerably shorter time than scaffolding to direct weathering and the associated corrosion. Also unlike scaffolding, the body of a vehicle is covered by numerous layers of paint.
  • the EP 068 67 39 proposes an L-shaped spring, which is introduced by a pivoting movement about the longitudinal axis of the profile in a complementary groove of the adjacent profile so that it forms an undercut in the groove of the adjacent hollow profile, which prevents withdrawal in the horizontal direction.
  • the DE 94 137 22.6 also presents a profile variant with an undercut through an L-shaped profile approach.
  • the force can be transferred to the neighboring profile piece, the profile of DE 94 137 22.6 in addition to the undercut in a groove hooked L-shaped profile attachment still secured by a locking connection in this position.
  • a disadvantage of this locking connection is that it is arranged at the end of each of a web of the two adjacent profile pieces. Since a professionally designed extruded profile as far as possible in all areas has a constant wall thickness so that it does not twist and warp during cooling, a locking connection, which is supported on one side of the profile, secured only with half of the possible by a two-sided suspension force.
  • the height of the two interlocking latching noses is to be selected relatively large, whereby the pivoting of the profile section required for latching increases and thus the risk of a fatigue fracture increases.
  • the invention has taken on the task of developing a multi-part scaffold floor, its own weight is low with the usual stability and resilience or that is particularly lightweight in relation to the load capacity and over the entire length of the profile away manually with particularly high security is tangible.
  • each profile consists of at least two hollow chambers, which are each shaped as a general hollow cylinder and whose wall thickness is substantially the same everywhere substantially and which each have a part of their wall with at least one adjacent hollow chamber in common and at least one latching Connecting element on both longitudinal sides in each case part of the wall of a hollow chamber and at the bottom of each profile at least one grip groove is formed as a part of the wall of at least one hollow chamber.
  • the most important feature of the invention is the dual use of the walls of the hollow chambers: First, they create the stability of the scaffold floor, by deriving its burden. Thanks to the design as a hollow chamber only relatively little material is needed for it, so the profile is relatively easy. Since the walls of the hollow chambers are completely closed in the scope, they cause a full sufficient stability with the required safety reserve despite a relatively small wall thickness.
  • a very simple embodiment still resembles the well-known from the timber construction tongue and groove boards, as that they are also connected via a groove in a board and a complementary spring in a neighboring board, but with the two essential differences that the "board” is no longer a solid body, but at least a double hollow body and the two horizontal surfaces of the groove and the spring to a Connecting element are removed.
  • this connecting element is a latching connection. It consists - as each locking connection - from a respective locking lug on the two surfaces to be joined together, which are partially complementary to each other and form an undercut in the potential extension direction. Both detents are pressed together by permanently elastic elements.
  • this single web must be sufficiently stiff to apply the necessary contact pressure, so that the profile is held together and, on the other hand, sufficiently elastic for it to be able to detach itself again from its counterpart.
  • the greatest load on this connection is achieved when a nearly punctiform load, such as a corner of a falling plate strikes a profile piece of Gerüstrastêts and thereby twisted.
  • the limit for this load case is reached when the two locking lugs separate from each other, so that the two adjacent profile pieces are separated from each other and then the load is no longer of at least one adjacent profile piece is carried along, but must be taken in full by the affected profile piece itself.
  • a possible countermeasure would be the further stiffening of the resilient web. However, this would run counter to an optimal design of an extruded profile, which should have a constant wall thickness in all possible areas, so that it hardens evenly and without distortion and without distortion after extrusion.
  • the invention proposes to suspend the latch not only on one side, but on two sides resiliently. This is the easiest to achieve when the walls of the profile itself is used as a suspension of the latch, which are also elastic in the wall regions of the profile thanks to the extrusion technology optimally selected, uniform wall thickness everywhere, as the molded webs.
  • each cavity itself.
  • a solid metal plate is too heavy as a scaffolding floor.
  • a first weight reduction is achieved in that vertical webs are formed on the underside of a thinner plate. Because these webs at their lowest edge the biggest burden - experienced by tensile forces - they are widened there T-shaped. A more sustainable structure arises when the legs of adjacent T's are connected together to form a hollow body.
  • each profile of the Gerüstrastitzs consists of at least two hollow bodies. As a result, a further increased load-bearing capacity is achieved with a relatively much higher overall weight ratio.
  • a human hand then transmits the highest tensile force when the fingers and the back of the hand form a J as seen from the side and grasp the object between this J and the thumb. Then the uppermost member of the fingers forms an undercut acting in the pulling direction.
  • the invention proposes that the underside of one of the at least two hollow chambers of each profile is arranged closer to the top of the profile than an adjacent, other hollow chamber.
  • a shoulder forms on the partition wall between the two hollow chambers at the bottom, behind which the first member of a finger can grip.
  • This paragraph should therefore correspond approximately to the length of the inside of the uppermost limbs of the fingers of a human hand in an angled condition. It makes sense that it can be extended by the material thickness of a typical work glove. This corresponds to an absolute number of the order of 26 mm.
  • the hollow chamber which is larger than the surface of the profile, at the edge of each profile has a cross-section which is adapted in its dimensions to a clasp by a human hand. Then the thumb rests on the top of the profile, the metacarpal bones on the side edge of the profile and the fingers with the inner links on the underside of the hollow chamber and the last link of each finger on the outside of the extension of the partition wall between the two hollow chambers.
  • each profile piece on three hollow chambers namely at the edge of each two large hollow chambers whose bottom is further removed from the top, as in the middle hollow chamber. Then the profile section can be taken quickly and safely even when Verklipsen to a scaffolding floor.
  • the scaffold floor consists of several identical profiles, for example extruded aluminum profiles, which can be manufactured according to the current state of the art of specialized companies at a relatively low cost.
  • a connecting element can be arranged near the upper edge and near the lower edge of each longitudinal side.
  • Mating Since a latching connection to overcome the locking point always requires a high force, it is a useful option to make a pair of fasteners as connectors. Mating has the advantage of a relatively low joining force during assembly, whereby the person to be mounted or the assembly machine can be more focused on the accuracy.
  • the application of this high force for the latching is to be facilitated by the fact that the next profile to be clipped is itself used as a lever. Since the profiles are usually much wider than high, the invention proposes that on the longitudinal side of a pivot axis is provided, around which the profile to be applied can pivot, while the locking connection is closed. This pivoting follows in time to the insertion and activates the locking connection.
  • a tongue is formed on the profile, which extends inclined to the edges of the profile.
  • This tongue is arranged on the lower edge of the longitudinal side and engages in a groove on the underside of the adjacent profile. Because the tongue is inclined to the edges of the profile, both profiles are also inclined to each other during mating, so are in a position in which they still need not make a stable connection. Therefore, the tongue can be inserted with a lot of play in the groove, which facilitates the assembly very much.
  • the tongue can pivot within the groove.
  • the two profiles can be pivoted against each other and placed in their actual desired, aligned angular position.
  • a scaffolding floor according to the invention is characterized by the following features:
  • a projection is formed near the upper edge, which engages in a complementary recess of the adjacent, second longitudinal side.
  • a locking lug is arranged, which engages behind a complementary locking edge on the recess.
  • Another pair of fasteners on the underside is a plug-in and pivot connection: On the profile of the first longitudinal side near the lower edge of a tongue is formed, which is aligned with respect to the bottom and the longitudinal side of the profile inclined. It engages in an inwardly widening groove on the underside of the adjacent profile. After pivoting the two profiles against each other, it lies partially on the inner surface of the groove.
  • the second longitudinal side passes at its lower edge in a holding web, which snuggles into the V-shaped notch between the root of the tongue and the first longitudinal side and slides there during the pivoting along.
  • connection of two profiles is a very simple process that can be performed manually for ordinary dimensions of scaffold floors easily by a single person or very much for mass production is easy to automate.
  • the tongue is inserted into the groove on the underside of a profile at the lower edge of the longitudinal side of another profile. Since the tongue is aligned obliquely both to the underside of the profile and to its longitudinal side, the two first profiles are also obliquely aligned with each other when inserting the tongue into the groove.
  • the groove It is a special feature of the groove that it widens inwards from its entrance opening.
  • the tongue can be pivoted within the groove, while the two profiles pivot against each other, wherein the pivot axis extends at the root of the tongue or within the groove.
  • the two adjacent longitudinal sides of the two profiles to be connected move towards each other.
  • the projection moves on the upper edge of the one longitudinal side to the complementary recess of the adjacent other longitudinal side.
  • the locking lug on the underside of the projection always further approaches to the complementary locking edge on the recess of the other, adjacent profile.
  • an inclined surface is formed in the locking lug, which is formed complementary to a similar inclined surface adjacent to the locking lug.
  • These two inclined surfaces slide briefly before the latching of the two components on each other, as it is known, for example, the closing wedge and the striking plate of a room door anyone.
  • the projection is somewhat deformed so that the latching nose can move over the latching edge. If this point is exceeded, the projection jumps back by the elasticity of the material back to its original shape and the locking lug is now engaged behind the locking edge.
  • the tongue has further pivoted within the groove and now abuts against the inwardly and downwardly facing part of the wall of the groove.
  • the front part of the groove which also forms the longitudinal side of the profile and acts as a holding web in the locking connection, is pivoted into the V-shaped notch between the root of the tongue and the associated longitudinal side and lies in the depth of the notch ,
  • the pivot axis is the lower edge of the retaining web.
  • the projection of the one profile is supported in the recess of the adjacent profile.
  • the leading edge of the projection can roll on the surface of the recess at a very small angle.
  • This tiny pivoting angle is limited by the play of the retaining web within the V-shaped notch between the root of the tongue and the first longitudinal side and by also very little play between the tongue and its bearing surface within the inner surface of the groove.
  • the head pieces can be glued to the profiles, they can be shrunk on it they can be welded on or permanently connected to the profiles by clinching. These proven connections are applicable without restriction and enable durable and robust scaffolding floors.
  • the center piece of the U-shaped profiled head piece at a distance to the end edges of the profile. This creates slits that serve as drainage.
  • moisture can penetrate between the head piece and the profiles in an approach of the head piece without seal, but not long escape at the same pace, so that disturbing amounts of water can accumulate in the cavity, there and back slosh and can flow with an inclination of the profile through the then sharply rising water pressure as a disturbing beam on the mining crew.
  • the simplest countermeasure is an enlargement of the gap between the head piece and the profile edge. As a result, although a little more water enters, but then flows away at the same pace immediately.
  • the two head pieces serve to further stiffen and stabilize the Gerüstrastêts.
  • Another important function of the head pieces is the connection with the standardized fastening elements of the framework. There are e.g. Holes or other openings usual. Also common are hooks, which are placed from above on struts of the scaffold or other fasteners.
  • the headers may also serve as hangers for transporting the scaffolding member profiles in a vertical position by engaging a hook in the handle groove formed by the inwardly drawn second hollow chamber and engaging behind the header. If e.g. the hook of a crane should be too big for it, an oval intermediate piece can make the connection.
  • the respective outer profiles can be provided on their outer sides with beads which are formed complementary to the adjacent edge. If multiple scaffolding floors are stacked on top of each other, these beads will grip around the edge of the scaffolding floor underneath to prevent slipping sideways.
  • the invention proposes that the beads point downwards. They then preferably engage in recesses, heels or constrictions of the underlying scaffolding floor.
  • This orientation has the advantage that the beads on the top of the scaffolding floors do not form a tray in which moisture accumulates and together with dirt forms a slippery lubricating film or even freezes and becomes dangerous ice.
  • edge profiles are used for this, instead of the fasteners on the upper edge have a paragraph in the profile and at the lower edge a complementary bead that engages when stacking in the shoulder of the underlying edge profile and does not interfere with the use in the framework ,
  • Such a profile is not limited to aluminum, but in principle also applicable to other metals or alloys. In principle, very similar is the extrusion of plastics. Particularly interesting is the addition of stabilizing, thin fibers, which increase the resilience of the profile.
  • the profile of a Gerüstrastêts invention is in principle also produced by bending a metal strip or more, interconnected metal strips.
  • FIG. 1 is an inventive Gerüstrastêt shown as a completely assembled unit in perspective; namely with a view of the lower sides 3 of the profiles P.
  • 4 interconnected with each other at their longitudinal sides profiles P are additionally connected to each other at its two end faces by a respective head piece K.
  • Each of the profiles P shows over the entire length of the recessed grip on its underside, which is formed by a hollow chamber H in each profile P, the bottom 3 forms a paragraph to the bottom 3 of the adjacent hollow chamber H and the gripping when mounting and dismounting facilitated.
  • the outer profiles P differ from the two inner profiles P by the bead W at the lower edge, which serves as a guide when stacking several scaffolding floors.
  • FIG. 1 shows an important feature of the invention, namely the longitudinally extending grip groove G, which is recessed against the adjacent lower sides 3, thereby enabling a hooking of the fingers of a human hand when handling. Since each of the connected here to a Gerüstrastêt profiles P has such a grip groove G, are in FIG. 1 four of these grooves G recognizable. The two inner ones were especially important in the assembly of the scaffolding load floor of the four profiles P. For the finished composite Gerüstrastêt especially the two outer are of importance.
  • FIG. 1 serves the overview of the arrangement of the profiles P and shows the connection of the profiles P by two head pieces.
  • the connection of the profiles P by latching and latching is in FIG. 1 not recognizable, since the front side of the profiles P is covered by the head pieces K. After removing the head pieces K, the perspective of
  • FIG. 2 Here, in a perspective view from the upper side 4 forth, two profiles P and their cross sections as a drawing separated from a Gerüstrastêt corner.
  • FIG. 2 shows all the details of the locking connection and makes it clear that the longitudinal sides 1 and 2 of the profiles P are no flat, continuous walls. Rather, in each case a projection 11 protrudes into a recess 21 of the adjacent profile P at its upper edges. At the lower edge of the longitudinal sides, a tongue 13 is inserted into the groove 23 of the adjacent profile P.
  • FIG. 2 shows very clearly and clearly the distribution of a profile P in several hollow chambers H. Between two first hollow chambers H1 at the edges of a profile P in the middle of a second hollow chamber H2 is inserted. The distance lower edge 3 of the central hollow chamber H2 to the upper edge 4 of the profile P is less than the distance of the adjacent hollow chambers H1 to the surface 4th
  • first hollow chamber H1 Left in FIG. 2 At the edge of the scaffold floor is a special form of the first hollow chamber H1 can be seen: Instead of connecting means it is provided at the outer lower edge with a downwardly facing bead W. This bead W is complementary to a recess A shaped. Each edge profile of a Gerüstrastêts has at both outer edges depending on such a recess A, in which when stacking a plurality of scaffolding floors above each other engages the bead W of the next Gerüstrastêts lying thereon
  • FIG. 2 shows very well that at the top 4 of the profile P no fluid accumulations can form, since there are no side walls that hold liquids back. This is an essential difference to other, non-inventive profiles that arrange the Stapelwulst on the top.
  • FIG. 2 Right in FIG. 2 is a profile P shown only half: the middle, to the formation of the grip groove G retracted inward hollow chamber H2 is partially cut off graphically and only the left of the two hollow chambers H1 shown with complete profile. It can be seen how above a connecting means is formed as a latching connection in the projection 11 and below a connecting means is formed as a plug and pivot connection.
  • FIG. 3 It shows the cross section through two adjacent profiles P and only the area of two, contacting longitudinal sides 1 and 2 in the embodiment according to claim 8.
  • Das in FIG. 3 drawn right profile P points at the top of the first Long side 1 a projection 11, marked here by a double arrow.
  • This protrusion 11 projects into the recess 21 from the second longitudinal side 2 of the adjacent, left-hand profile P.
  • the projection 11 is formed complementary to the recess 21, so that the upper sides 4 of the two adjacent profiles P are aligned in a plane with each other.
  • FIG. 3 clearly shows how before the latching lug 12 and behind the locking edge 22 depending a wedge-shaped contact surface is formed, which slide when mounting each other and thereby press the right-hand profile P apart by a very small degree and the left-hand profile P by a very small Squeeze measure, so that the locking lug 12 can slide over the locking edge 22 by means of the two contact surfaces and behind the locking edge 22 engages.
  • FIG. 3 is very easy to understand, as required for locking the locking lug 12 with the locking lug 22 spring movement is distributed in each case on the walls on both sides.
  • FIG. 3 It is easy to see how a force acting vertically on top 4 is absorbed by the tongue-and-groove connection. If a vertical force vector presses on the right-hand profile P, it propagates through the profile and also acts on the tongue 13. Since the edge of the tongue 13, like the complementary groove 13, is inclined relative to the underside 3, it acts Arrangement like an inclined plane; ie, the tongue 13 slides on the inner surface of the groove 23. Without the holding web 24, the right-hand profile P would thus migrate away from the left-hand profile P and the connection would be released.
  • this movement is the holding web 24 in the way, which engages in the V-shaped notch 14 between the root of the tongue 13 and the first longitudinal side 1.
  • the retaining bar 24 blocks the sliding movement of the tongue 13 on the inner surface of the groove 23 and thus ensures the bond between the two profiles P. Therefore, the vertical force vector is derived from the tongue 13 on the inner surface of the groove 23 and thus on the left profile.
  • FIG. 3 shows two adjacent profiles P in the locked state. The leading snap action is shown in
  • FIG. 4 In the FIG. 3 drawn sections of two adjacent profiles are reduced graphically to two, very short profile segments.
  • the pivoting of the right profile P against the left profile P is represented by an arrow at the top of the picture and in the center of the picture. It is understandable that in a further pivoting of the right profile P, the pivot axis lies approximately in the region of the V-shaped notch 14 and on the lower edge of the retaining web 24. As a result, the contact surface of the latching lug 12 slides along the contact surface of the latching edge 22 along.
  • FIG. 4 illustrates how the narrow projection 11 of the right profile P is slightly raised when sliding these two surfaces, so that the locking lug 12 slides over the locking edge 22 away and snaps into the recess 21 behind the locking lug 22.
  • FIG. 4 shows how the tongue engages at the lower edge of the one profile P only in a corresponding counterpart of the other profile P and then pivoted therein and as on the upper edge of the two adjacent profiles P, the locking lug 12 engages behind the locking edge 22.
  • the disassembly of two interconnected profiles P is possible in reverse order.
  • the left profile P is meaningfully clamped or otherwise blocked.
  • the connection between the locking lug 12 and the locking edge 22 is released, z. B. by depressing the top 4 of the left profile P and by a slight lifting of the projection 11 on the right profile P.
  • the tongue 13 is also pivoted further and further until it is almost parallel to the second longitudinal side 2 of the left profile P runs. In this state, the tongue 13 can be removed from the groove 23 by the right profile P is moved vertically downward.
  • FIG. 4 makes it clear how easy and nevertheless secure the connection of the two adjacent profiles P takes place and how quickly disassembly is possible again. This makes it realistic that z. B. damaged profiles P can be removed from an otherwise still fully suitable Gerüstrastêt and replaced by a single, new profile P.
  • FIG. 5 the front sides of three stacked scaffolding floors are drawn, as well as in FIG. 2 only the left edge, each with a fully represented and a half drawn professional pl. Die FIG. 5 illustrates very clearly how at the bottom of each profile P and that at the outermost first hollow chamber H1 a bead W is attached. This Bead W engages in the recess A of the next, underlying profile P, thereby preventing lateral slippage of the stack. In the FIG. 5 embodiment shown also uses the beads W even as a spacer element to make between the stacked profiles P in the vertical direction at a distance, so there is no moisture permanently holds or even smaller soils affect the stackability.
