[0003] Scaffolding post and scaffold with one scaffolding post Description
[0004] The present invention relates to a scaffold post which can be integrated as an additional component into a scaffold, such as a construction scaffold, grandstand scaffold or scaffold tower, in order to increase the structural strength and / or to subdivide a scaffold bay bounded between vertical posts and horizontal beams, for example to provide an access point.
[0005] A scaffold post marketed by Brand Industrial Services, Inc. under the designation SAGP features a tubular post body with essentially U-shaped support heads at its axial ends. These support heads have recesses that open outwards from each other along the post's longitudinal axis. Horizontal ledgers of a scaffold, positioned directly above one another, can be accommodated in these recesses, thus holding the scaffold post between them. This allows the post to subdivide a scaffold bay formed between and coupled to vertical standards, for example, to provide access to a ladder running along the outside of the scaffold.
[0006] The object of the present invention is to provide a scaffold post which offers increased variability in its integration into a scaffold to be built with it.
[0007] According to the invention, this problem is solved by a scaffold post comprising: a post body elongated in the direction of a post longitudinal axis, a first support head at a first axial end region of the post body for supporting the scaffold post with respect to a first scaffold girder of a scaffold, wherein the first support head has a first support recess open axially away from the post body in a first direction, wherein, when the scaffold post is supported with respect to the first scaffold girder, the first scaffold girder is at least partially received in the first support recess, 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0008] - 2 - at a second axial end region of the post body, a second support head for supporting the scaffold post with respect to a second scaffold beam of the scaffold, wherein the second support head has a second support recess open axially away from the post body in a second direction opposite to the first direction, wherein, when the scaffold post is supported with respect to the second scaffold beam, the second scaffold beam is at least partially received in the second support recess.
[0009] At least one support recess of the first support recess and the second support recess comprises a first recess section providing an axial opening area and at least one second recess section extending axially from a bottom area of the first recess section towards the post body.
[0010] By providing such a stepped support recess with its two recess sections, differently shaped scaffold beams or differently shaped and dimensioned sections of a scaffold beam can be supported on such a scaffold post. For example, it is possible to support horizontal beams used as scaffold beams with or without a stiffening element against a scaffold post constructed according to the invention. This reduces the number of differently shaped scaffold components required for erecting a scaffold.
[0011] The first recess section can have a first recess geometry that substantially corresponds to the cross-sectional geometry of a section of a scaffold support, preferably a scaffold support body, to be accommodated in the first recess section. It should be noted that, within the meaning of the present invention, such correspondence or adaptation to the cross-sectional geometry means an adaptation to the cross-sectional shape as well as the cross-sectional size of the support body, so that the support body can be accommodated without substantially altering its shape. 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0012] - 3 - ches movement game in which this receiving first recess section can be included.
[0013] In particular, if such a scaffold support body has a circular cross-sectional geometry, it is advantageous for a comprehensive support interaction if the first recess section is bounded by a first edge region of the support head having at least one support recess that is at least partially curved in a substantially circular manner.
[0014] Advantageously, the first radius of curvature of the first edge region is essentially constant to adapt to the cross-sectional shape of a scaffold support beam body.
[0015] For the support interaction with scaffold supports designed with a substantially rectangular outer circumferential contour, it is proposed that the first recess section is bounded by a first edge area of the support head, which has at least one support recess, that is at least partially substantially rectangular.
[0016] The first edge area can comprise two longitudinal edge sections that are essentially parallel to each other and to the longitudinal axis of the post, and a transverse edge section that is essentially orthogonal to the longitudinal axis of the post and provides the ground area, so that an essentially U-shaped edge geometry is formed.
[0017] The at least one second recess section can have a second recess geometry that essentially corresponds to the cross-sectional geometry of a section of a scaffold beam to be accommodated in the second recess section, preferably a scaffold beam stiffening body, a scaffold beam support body, or an anti-lift device. Particularly in areas where especially high strength is required in a scaffold, it is advantageous to use horizontal beams as scaffold beams which, attached to a scaffold beam support body, have a scaffold beam stiffening body that generally stiffens the latter at its lower, vertically positioned area. (See 68585P DE Wilhelm Layher Verwaltungs-GmbH)
[0018] - 4 -
[0019] In the support interaction with the scaffold post according to the invention, the latter can be received in a second recess section of a support recess adapted to it in shape and size.
[0020] The second recess section can be bounded by a second edge region of the support head, which has at least one support recess, that is at least partially curved in a substantially circular fashion. To adapt to the generally plate-like cross-sectional geometry of such a stiffening body, the second recess section can be designed as an elongated hole.
[0021] A second radius of curvature of the second edge region can be essentially constant to adapt to, for example, the partially circular cross-sectional geometry of a scaffold support stiffening body.
[0022] To maintain the stepped dimensioning of the two recess sections provided according to the invention with respect to the dimension transverse to the longitudinal axis of the post, the second radius of curvature can be smaller than the first radius of curvature.
[0023] In an alternative embodiment, to adapt to the cross-sectional geometry of a scaffold support, the at least one second recess section can be bounded by a second edge area of the support head, which has at least one support recess, that is at least partially essentially rectangular.
[0024] The second edge area can comprise two longitudinal edge sections that are essentially parallel to each other and to the longitudinal axis of the post, and one transverse edge section that is essentially orthogonal to the longitudinal axis of the post.
[0025] To adapt to different circumferential contours of the two scaffold beams to be supported with respect to the scaffold post, the scaffold post according to the invention can be provided with a support head of first support head and second support head having a support recess with a first recess section 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0026] - 5 - and a second recess section, and that the other support head of first support head and second support head includes a support recess with a first recess section and without a second recess section.
[0027] In an alternative embodiment of the scaffold post according to the invention, a support head of first support head and second support head can comprise a support recess with a first recess section and a second recess section, and the other support head of first support head and second support head can comprise a support recess with a first recess section and two second recess sections arranged transversely to the longitudinal axis of the post at a distance from each other.
[0028] In order to compensate for variations in the mutual distance between the two scaffold supports with respect to which the scaffold post is to be supported, in the support interaction of the scaffold post with scaffold beams of different shapes and corresponding dimensions made possible by the invention, it is proposed that the post body comprises a first post part supporting the first support head and a second post part supporting the second support head, wherein the first post part and the second post part are movable relative to each other in the direction of the post's longitudinal axis and can be locked in a plurality of axial relative positions relative to each other.
[0029] Further increased variability in the use of a scaffold post constructed according to the invention can be achieved by providing a toeboard locking mechanism for a scaffold toeboard at at least one axial end region of the first axial end region and / or at at least one support head of the first support head and second support head. The possibility of attaching a toeboard to the scaffold post as a lateral safety device is particularly advantageous when the scaffold post is used to limit access to the scaffold. 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0030] - 6 -
[0031] For example, the toeboard locking mechanism can include a locking projection extending radially away from the post body and towards the other axial end region of the post body.
[0032] If the locking projection is provided on the other support head, this functionality for coupling with a toeboard is provided in relation to the support head which is generally to be positioned at the bottom in the vertical direction.
[0033] To further increase stability or safety in a scaffold, a plurality of coupling elements arranged at intervals along the longitudinal axis of the post can be provided on the post body.
[0034] For example, the coupling elements can be designed as perforated discs, so that they can be easily coupled to wedge heads provided on scaffold supports, such as horizontal beams or diagonal beams.
[0035] According to a further aspect, the present invention relates to a scaffold, in particular a construction scaffold, grandstand scaffold, or scaffold tower, comprising a basic scaffold with a plurality of vertical uprights extending substantially in a vertical direction and a plurality of horizontal ledgers extending substantially in a horizontal direction and coupled to the vertical uprights. The scaffold further comprises at least one scaffold post constructed according to the invention, wherein a support head of the first support head and second support head of the at least one scaffold post is supported with respect to an upper horizontal ledger by two horizontal ledgers positioned directly one above the other in the vertical direction, and the other support head of the first support head and second support head of the at least one scaffold post is supported with respect to a lower horizontal ledger of the two horizontal ledgers positioned directly one above the other in the vertical direction.68585P DE Wilhelm Layher Verwaltungs-GmbH.
[0036] - 7 -
[0037] For increased stability or safety, at least one horizontal beam and / or at least one scaffold toeboard can be coupled to at least one scaffold post and at least one vertical post or another scaffold post positioned horizontally next to it.
[0038] For coupling with scaffold beams which have a stiffening body on their underside, one support head, i.e. the support head which also has the second recess section, for example, can be supported with respect to the upper horizontal beam, and the other support head, i.e. the support head which only has the first recess section or the first recess section and two second recess sections, for example, can be supported with respect to the lower horizontal beam.

[0057] Figures 1 and 2 show a section of a scaffold 10 used, for example, as a construction scaffold. The scaffold 10 comprises a basic frame 12 with a plurality of vertical uprights 14 positioned one above the other and next to each other, and attached to these 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0058] - 9 - coupled and thus also connecting horizontal beams 16. On a group of four horizontal beams 16, visible in the lower area of the basic frame 12, positioned at the same height in a vertical direction V and extending in a horizontal direction H, floor elements 20 of the basic frame 12 are suspended from the shorter horizontal beams 18, so that these horizontal beams 16, 18 and the floor elements 20 supported on them form a working platform 24. A ladder 22 is arranged on an outer side of the basic frame 12 and attached to the vertical uprights 14 positioned in a corner area of the basic frame 12.
[0059] A scaffold bay 26, defined in the area of the work platform 24 by two vertical uprights 14 positioned directly next to each other and two longer horizontal ledgers 16 positioned directly above one another, is subdivided by a scaffold post 28, forming an entrance 32 that can be closed by a gate 30. The area of the scaffold bay 26 located between the scaffold post 28 and the vertical upright 14 positioned to its left in Figures 1 and 2 is secured by two shorter horizontal ledgers 34 positioned one above the other and a toeboard 36 connected to the lower part of the scaffold post 28 or the vertical upright 14.
[0060] The structure of the scaffold post 28 integrated into the basic framework 12 is described in detail below with reference to Figs. 3 to 12.
[0061] Fig. 3 shows the scaffold post 28 in a side view. The scaffold post 28 comprises a post body 38 elongated in the direction of a post longitudinal axis L. The post body 38 is constructed with a first post section 40, positioned at the top in the vertical direction V when the scaffold post 28 is integrated into the base frame 12, and a second post section 42, which telescopically receives the first post section 40. The two post sections 40, 42 can be designed as tubes, for example, metal or steel tubes. The first post section 40 and the second post section 42 are movable or displaceable relative to each other in the direction of the post longitudinal axis L and can be locked in different axial relative positions by locking elements 46 passing through openings in the two post sections 40, 42. 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0062] - 10 - can be locked together, allowing the scaffold post 28 to be provided in different lengths.
[0063] A first support head 50, for example in the form of a plate, is provided in a first axial end region 48 of the post body 38, which is formed on the first post section 40 of the post body 38. The first support head 50 can be attached to the first axial end region 48 of the first post section 40 and fixed thereto, for example by welding. A second support head 54 is provided in a second axial end region 52 of the post body 38, which is formed on the second post section 42. The second support head 54 can be attached to the second axial end region 52 of the second post section 42 and fixed thereto, for example by welding.
[0064] Figure 5 illustrates, in a schematic representation, the first support head 50 provided at the first axial end region 48 of the post body 38. This head has a first support recess 56, which is open axially in a first direction Ri away from the post body 38. The first support recess 56 has two axially successive or adjoining support areas 58, 60 with different geometries.
[0065] The first recess section 58, which provides one axial opening region 62 of the first support recess 56 and is located further away from the first axial end region 48, has a circular first recess geometry adapted to the outer circumferential contour of the horizontal beams 16 and 18, respectively, and is bounded by a substantially circularly curved first edge region 64 of the first support head 50. The first recess geometry of the first recess section 58 is adapted to the circular cross-sectional geometry of the horizontal beams 16 and 18 in terms of both shape and size. A first radius of curvature Ki of the first edge region 64 is substantially constant and corresponds substantially to the radius of the horizontal beams 16 and 18.The first recess section 58 thus corresponds in terms of its shape and size essentially to the shape and size of the horizontal beams 16, 18 to be accommodated therein, so that when support interaction is established the horizontal beams 16, 18 68585P DE Wilhelm Layher Verwaltungs-GmbH.
[0066] - 11 - without significant movement, partially incorporated into the first recess section 58 and supported at the first edge area 64.
[0067] This support interaction between the first support head 50 and the horizontal beam 16, positioned in the vertical direction V directly above the scaffold post 28, is illustrated in Fig. 6. The horizontal beam 16, which, according to the present invention, is to be considered a scaffold beam supported with respect to the scaffold post 28, has, in the position of the scaffold post 28 in the base frame 12 as also shown in Fig. 1, a scaffold beam support body 66 with the tubular shape with a circular outer circumference, as also shown in Fig. 7. The horizontal beam 16, or rather its scaffold beam support body 66, is received in the first recess section 58 of the first support head 50 by means of this circular outer circumference.
[0068] The second support head 54, provided at the second axial end region 52 of the post body 38, also has a second support recess 68, visible in Fig. 4. This recess is open axially away from the post body 38 in a second direction R2, opposite to the first direction Ri. The second support recess 68 of the second support head 54 also has a first recess section 70, corresponding to the design of the first support head 50. This first recess section 70, adapted to the circular outer circumferential contour of the horizontal beam 16 positioned in the vertical direction V below the scaffold post 28, or its scaffold support beam body 66, has a substantially circular recess geometry and is bounded by a first edge region 72 of the second support head 54.
[0069] Since the scaffold post 28 interacts with two parallel horizontal beams 16, the two post sections 40, 42 and the support heads 50, 54 provided thereon are oriented relative to each other such that the opening center axes Mi, M2 of the support recesses 56, 68 are essentially parallel to each other. 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0070] - 12 -
[0071] The support interaction of the second support head 54 with a horizontal beam 16 is illustrated in Fig. 7. In particular, Fig. 7 shows the support of two scaffold girders 28 positioned one above the other in the vertical direction V with respect to the same horizontal beam 16. The first support recess 56 provided on the first support head 50 of the lower scaffold girder 28 and the second support recess 68 provided on the second support head 54 of the upper scaffold post 28 are coordinated with their respective first recess sections 58, 70 such that almost half of the outer circumference of the scaffold girder support body 66 of the horizontal beam 16 is accommodated in each of these two first recess sections 58, 70, without the two support heads 50, 54 touching each other.This ensures that in the area of support of each support head 50, 54 a maximum support interaction is created on the horizontal beam 16 and that the horizontal beam 16 is held stably between the two scaffold posts.
[0072] While the support recess 68 provided in the second support head 54 has only a first recess section 70, the first support recess 56 provided on the first support head 50 also has the second recess section 60 visible in Fig. 5. This section adjoins the first recess section 58 in a base area 74, i.e., an area of the first edge region 64 extending approximately orthogonally to the longitudinal axis L of the post. The second recess section 60 can have an elongated, hole-like structure oriented in the direction of the longitudinal axis L of the post and, at least in its area limited in the axial direction towards the first post part 40, be bounded by a circularly curved second edge region 76 of the first support head 50. The second boundary region 76 can also have an essentially constant second radius of curvature K2, which, as Fig. 5 clearly shows, is smaller than the first radius of curvature K1.
[0073] The first support recess 56 provided on the first support head 50 thus has a stepped overall structure with its two recess sections 50, 60, in which the maximum or also the average width of the first recess section 58 transverse to the longitudinal axis of the post is generally greater than the maximum or average width of the second recess section 60 transverse to the post. 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0074] - 13 -
[0075] Longitudinal axis L. The transition between the two recess sections 58, 60 can be edge-like or can be rounded with a curvature opposite to the direction of curvature in the first edge area 64 and the direction of curvature in the second edge area 76.
[0076] Figures 8 to 10 show the scaffold post 28 with its two support heads 50, 54 in a supporting interaction with a shorter horizontal beam 18. These shorter horizontal beams 18, each forming a scaffold girder according to the present invention, also have a scaffold girder support body 78, for example, tubular and with a circular cross-sectional geometry, which is reinforced or stiffened on its lower side when installed in the base scaffold 12 by a scaffold girder stiffening body 80. The scaffold girder stiffening body 80 can, for example, be formed in a plate-like shape by bending a sheet metal into a U-shape and welded to the scaffold girder support body 78. Such stiffening of the horizontal beams 18 can be particularly advantageous if they also serve to support the base elements 20.
[0077] A second recess geometry of the second recess section 60 of the first support head 50 is adapted to the cross-sectional geometry of the scaffold girder stiffening body 80. The scaffold girder stiffening body 80 rests with its end region positioned at the bottom in the vertical direction on the second edge region 76 and is received transversely to the post longitudinal direction L in the second recess section 60 without significant play.
[0078] Since the horizontal beam 18 shown in Fig. 8 has the scaffold girder stiffening body 80 only on its underside, it can interact on its upper side, or on the upper side of the scaffold girder support body 78, with a second support head 54 of a scaffold post 28 positioned above this horizontal beam 18 in the manner shown in Fig. 9, in the same way as described above with reference to a horizontal beam 16 on which no scaffold girder stiffening body is provided. 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0079] - 14 -
[0080] Depending on whether a scaffold post 28 is to be arranged between two horizontal beams 16 without a scaffold girder stiffening body or between two horizontal beams 18 with a scaffold girder stiffening body provided on each of them, the clear span between the horizontal beams 16 and 18, respectively, which support the scaffold post 28, varies. It can be seen in Fig. 8 that when the first support head 50 interacts with a scaffold girder stiffening body 80 provided on the underside of a scaffold girder support body 78, the first support head 50 is lower in the vertical direction V than if it were to be supported directly against the scaffold girder support body 78. In order to provide this required length variation, the two post parts 40, 42 are movable in the post longitudinal direction L and can be locked in different axial relative positions with respect to each other, as described above.
[0081] A toeboard locking device, generally designated 82, is provided on the second support head 54, which is positioned at the bottom of the scaffold post 28 integrated into the base frame 12 in the vertical direction V. The toeboard locking device 82 comprises a locking projection 84 extending radially from the second support head 54 along the second axial end region 52 in the direction of the post's longitudinal axis L at a distance from the second post section 42. As shown in Fig. 11, the toeboard 36 can be hooked onto the locking projection 84 from above by means of a hook-like locking element 88 provided thereon, so that the toeboard 36 forms a lateral safeguard against falling in the vertical direction V immediately adjacent to the base elements 20. Similarly, in its other end area, the toe board 36 can be fixed to one of the vertical posts 14 positioned directly next to the scaffold post 28, so that together with the two shown in the Fig.1 and 2, the shorter horizontal rails 34 in the area of the scaffold bay 26 next to the gate 30 provide triple lateral protection, i.e., protection at three different heights. If, for example, two scaffold posts 28 are to be arranged side by side in the scaffold bay 26 to provide two access points, the toe board 36 and the shorter horizontal rails 34 can be connected to the two adjacent scaffold posts 28. 68585P DE Wilhelm Layher Verwaltungs-GmbH.
[0082] - 15 -
[0083] Figures 12 and 13 show an alternative embodiment of a scaffold post 28 and its first support head 50, respectively. The cross-sectional geometry of the first support recess 56 is adapted to the essentially rectangular cross-sectional geometry and outer contour of the horizontal beam 18'. This beam has a scaffold girder body 66' with a substantially U-shaped cross-section, which, when integrated into the base scaffold 12, is essentially open upwards in the vertical direction. This horizontal beam 18', which provides an alternatively designed scaffold girder, can be used to suspend floor elements 20 with hook-like suspension elements.
[0084] Adapted to the rectangular cross-sectional geometry of the scaffold girder support body 66' of the horizontal beam 18', the first recess section 58 also has a substantially rectangular first cross-sectional geometry and is surrounded by a correspondingly shaped first edge region 64 of the first support head 50. The first edge region 64 comprises two longitudinal edge sections 90, 92 extending substantially in the direction of the post longitudinal axis L and a transverse edge section 94 extending between these substantially perpendicular to the post longitudinal axis L, which also provides the base region 74 of the first recess section 58, in which the second recess section 60 is open to the first recess section 58.
[0085] With the embodiment of the first support head 50 and the first support recess 56 provided therein, as shown in Figs. 12 and 13, it is thus also possible to generate a support interaction with horizontal beams 18', which, as shown in Fig. 13, are stiffened by a scaffold girder stiffening body 80'. This is connected to the underside of the U-shaped scaffold girder support body 78'.
[0086] In the horizontal beam 18' shown in Fig. 13, both the scaffold support beam body 78' and the scaffold support stiffening body 80' have a substantially rectangular cross-sectional profile. For example, these two components are formed by forming respective sheet metal blanks. To avoid sharp edges, the longitudinal ends of the U-shaped legs of the generally U-shaped beam can also be rounded. 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0087] - 16 - shaped scaffold support body 78' for example be flanged inwards.
[0088] Adapted to the rectangular cross-sectional geometry of the horizontal beam 18' in the area of the scaffold girder stiffening body 80', the second recess section 60 is also essentially rectangular. The second edge region 76 has two longitudinal edge sections 98, 100 extending essentially in the direction of the post's longitudinal axis L, and a transverse edge section 102 extending essentially transversely to the post's longitudinal axis L. The scaffold girder stiffening body 80' rests essentially flat on the transverse edge section 102 and is held transversely to the post's longitudinal axis L without significant play between the longitudinal edge sections 98, 100.
[0089] Since, in general, all horizontal beams positioned one above the other in a scaffold 10 or basic scaffold 12 have the same design, in the embodiment of a scaffold post 28 shown in Figs. 12 and 13, the second support head 54 shown in Figs. 14 and 15 is also designed with a second support recess 68, which has a rectangular first recess geometry adapted to the cross-sectional geometry of the horizontal beam 18' shown in Figs. 12 and 13.
[0090] Figure 14 shows that the second support recess 68 formed in the second support head 54 has a substantially rectangular first recess section 70. This provides the opening area 104 through which the second support recess 68 is axially open away from the post body 38. The first edge area 72 has two longitudinal edge sections 106, 108 that are substantially parallel to each other and to the longitudinal axis L of the post, and a transverse edge section 112 that extends substantially transversely to the longitudinal axis L of the post between the two longitudinal edge sections 106, 108 and provides a bottom area 110 of the first recess section 70.
[0091] Starting from this base area 110, two second recess sections 114, 116 extend. The second recess sections 114, 116 are transverse 68585P DE Wilhelm Layher Verwaltungs-GmbH
[0092] - 17 - arranged at a distance from each other along the longitudinal axis L of the post. Their mutual distance essentially corresponds to the distance between the two U-shaped legs of the scaffold support body 66' or the axial end regions of the same formed by crimping.
[0093] The second recess sections 114, 116 essentially have a cross-sectional geometry corresponding to that of the second recess section 60 of the first support head 50, as shown in Fig. 5. The second recess sections 114, 116 are surrounded by a second edge region 118 of the second support head 54, which is circularly curved, at least in the axial end region of the second recess sections 114, 116 furthest from the first recess section 70, and has a comparatively small second radius of curvature K2. This radius is approximately adapted to, or rather,slightly larger than the radius of curvature of the axial end regions of the U-legs of the scaffold support body 66' of the horizontal beam 18' formed by crimping, so that when the scaffold post 28 is placed on the horizontal beam 18', the axial end regions of the U-legs of the scaffold support body 66' formed by crimping are positioned in the apex regions of the second recess sections 114, 116 such that, on the one hand, a defined positioning of the scaffold post 28 with respect to the horizontal beam 18' is achieved and, on the other hand, no force is exerted on the U-legs of the scaffold support body 66' transversely to the post longitudinal axis L, either towards or away from each other.
[0094] Fig. 15 illustrates the support interaction of a scaffold post 28 with the second support head 54 shown in Fig. 14 and a horizontal beam 18', on which floor elements 20 with attached suspension elements 120 are supported. To prevent the floor elements 20 from lifting off the horizontal beam 18', an anti-lift device 122, which is essentially T-shaped in cross-section and extends essentially along the entire length of the horizontal beam 18', is positioned above the horizontal beam 18', overlapping the suspension elements 120. This anti-lift device has a T-head 124, the length of which transverse to the post's longitudinal axis L is greater than the corresponding length or width of the horizontal beam 18' transverse to the post. 68585P DE Wilhelm Layher Verwaltungs-GmbH

[0096] Longitudinal axis L. The dimension of the first recess section 70 of the second support recess 68' transverse to the post longitudinal direction L, i.e. the distance between the two longitudinal edge sections 106, 108, is adapted to the dimension of the T-head 124, so that when the scaffold post 28 or second support head 54 is standing on the lifting safety element 122, the lifting safety element 122 with its T-head 124 is received in the first recess section 70 in such a way that it rests flat on the transverse edge section 112 and is held transversely to the post longitudinal axis L without significant play between the two longitudinal edge sections 106, 108 in the area of a curvature-like transition area to the transverse edge section 112. The lifting protection element 122 with its T-head 124 covers the two second recess sections 114, 116.
[0097] The anti-lift device 122, provided in association with the horizontal beam 18', forms a scaffold support according to the present invention, with respect to which a scaffold post 28 is supported by its second support head 54, which is positioned downwards in the vertical direction V. The shape and dimensions of the first recess section 70 are adapted to the shape and dimensions of the anti-lift device 122, particularly in the area of its T-head 124.
[0098] Fig. 16 illustrates an alternative embodiment of a scaffold 10 in which a scaffold post 28 is integrated between two of the shorter horizontal beams 18 of the base scaffold 12. The horizontal beams 18 are designed as illustrated in Fig. 8 and have the scaffold beam stiffening body 80 on the underside of the respective scaffold beam support body 78. The support interaction of the scaffold post 28 with respect to these two vertically positioned horizontal beams 18 in the area of the first support head 50 and in the area of the second support head 54 takes place in the manner illustrated in Figs. 8-10.
[0099] In this scaffold 10 illustrated in Fig. 16, the scaffold post 28 primarily serves to stiffen the base scaffold 12. In principle, an access point could also be formed in the area next to the scaffold post 28, as illustrated in Fig. 2. 68585P DE Wilhelm Layher Verwaltungs-GmbH

[0101] A stable support for the scaffold post 28, which interacts with the horizontal ledgers 18 supported by it in their longitudinal direction, i.e., transversely to the post's longitudinal axis L, essentially only through frictional interaction, can in turn be achieved by, for example, two shorter horizontal ledgers 34 positioned one above the other, which connect the scaffold post 28 to one of the vertical uprights 14 positioned directly next to it. In order to realize this coupling by means of conventional horizontal ledgers, coupling elements 96, arranged at a distance from each other in the direction of the post's longitudinal axis L and designed, for example, as perforated discs, are provided on the post body 38 of the scaffold post 28, to which the horizontal ledgers 34 can be coupled with wedge heads provided thereon.
