Description

[0001] The invention relates to an intermediate scaffold platform and a scaffold with such an intermediate scaffold platform for scaffolding an object. The scaffold is designed and configured for scaffolding objects with a non-planar, i.e., round or angular, wall.

[0002] Such scaffold decks and scaffolds 200 are generally known in the prior art, for example from the German utility model DE 297 24 315 U1, see the Fig. 7 and Fig. 8. A plurality of adjacent scaffold towers 250-1, 250-2, each with a grid width R1, are disclosed, attached to the outside of an unplanar, here round, wall 32 of an object 30. Due to the round wall, the scaffold towers 250-1, 250-2 are arranged at an angle α>0° and at a mean distance with a grid dimension A from each other. Each of the scaffold towers has at least one scaffold platform 210, with two of the scaffold platforms 210 of adjacent scaffold towers being arranged at least approximately at the same height. Due to the angular arrangement and the distance between the two scaffold towers 250-1, 250-2, a trapezoidal gap 260 is formed between them, which also extends between the two scaffold platforms 210. The trapezoidal gap 260 is bridged by an intermediate scaffold floor 270 placed on the scaffold floors 210 of the scaffold towers to form a scaffold-encompassing working platform.The intermediate scaffold platform 270 can be installed because the grid dimension A of the distance between the adjacent scaffold towers is smaller than the length of the installed intermediate scaffold platform. The installed intermediate scaffold platform 270 is secured against unintentional loosening or displacement.

[0003] Due to its thickness, the intermediate scaffold platform 270 protrudes significantly compared to the scaffold platforms 210 of the scaffold towers 250-1, 250-2 and, disadvantageously, forms a dangerous tripping hazard on its end faces.

[0004] The invention is based on the objective of further developing a known intermediate scaffolding platform for bridging, for example, a trapezoidal gap between, for example, two adjacent scaffolding towers, wherein the gap is larger than the length of a plank of the intermediate scaffolding platform, and a known scaffolding in such a way that the gap can be closed in an alternative manner with a less high tripping hazard.

[0005] This problem is solved with regard to the intermediate scaffold platform by the subject matter of claim 1. Accordingly, the intermediate scaffold platform according to the invention is characterized by a decking element attached to at least one of the narrow sides of the planks, which extends the plank of the intermediate scaffold platform in its longitudinal direction, for attaching or placing the intermediate scaffold platform on / at an adjacent scaffold platform or scaffold beam of the scaffold.

[0006] The expression “extended in the longitudinal direction” does not necessarily mean that the longitudinal axes of the plank and the covering part are aligned with each other; rather, they can also form a preferably obtuse angle β+γ<180°.

[0007] This problem is solved with respect to the scaffolding by the subject matter of claim 7. Accordingly, the scaffolding according to the invention is characterized in that the intermediate scaffolding platform is designed according to one of the preceding claims, that the distance between the two scaffolding towers is greater than the length of the plank of the intermediate scaffolding platform, but less than the longitudinal extent of the plank together with the at least one decking element attached to it, and that the plank of the intermediate scaffolding platform is inserted into the, for example, trapezoidal gap and is supported by the decking element, which is attached at least on one of its narrow sides, on the first scaffolding platform or on a crossbeam of a scaffolding frame of the first scaffolding tower.

[0008] When the scaffold towers are arranged at an angle α>0, the term "distance" refers to the preferably average distance between the scaffold platforms, which are arranged at the same height in the scaffold towers.

[0009] Advantageously, the decking components serve as support brackets or support arms to brace the plank to which they are attached, and thus the entire intermediate scaffold platform. Unlike a standard scaffold platform, the installation of the intermediate scaffold platform according to the invention does not require a crossbeam of an adjacent scaffold frame to be precisely positioned, i.e., perpendicular to the longitudinal axis of the intermediate scaffold platform, so that the plank can be supported against it. Rather, the attached decking component can also bridge a triangular gap existing between the plank of the intermediate scaffold platform and the crossbeam, thus creating a safe working platform. In other words, the longitudinal axes of the intermediate scaffold platform and the scaffold platform of the adjacent scaffold can be at any angle to each other.

[0010] By inserting the plank of the intermediate scaffold platform into the trapezoidal gap between the platforms of two adjacent scaffold towers, the intermediate scaffold platform according to the invention can bridge gaps of, for example, up to approximately 2 m in width, particularly when the planks are standard scaffold platforms of standard lengths commonly used in scaffold construction. Finally, it should be noted as an advantage that when the platform is placed with its free end on the top of the scaffold platform of the adjacent scaffold tower and preferably also fastened there, it protrudes less than a traditional scaffold platform laid on top; therefore, the tripping hazard is significantly reduced in this case.

[0011] The use of the intermediate scaffold platform according to the invention is not limited solely to closing, for example, a trapezoidal gap between the platforms of two adjacent scaffold towers. Rather, the intermediate scaffold platform according to the invention can also be used to bridge rectangular gaps between two parallel scaffold towers or other gaps that are only bordered on one side or not at all by scaffold towers, but by other objects.

[0012] Advantageous embodiments of the invention are the subject of the dependent claims.

[0014] The invention is described below with reference in particular to the Fig. Figures 1 to 6 are described in detail in the form of exemplary embodiments. In all figures, identical technical elements are designated with the same reference numerals.

[0015] Fig. Figure 1 shows an intermediate scaffold platform 100 according to the invention for a scaffold 200 for scaffolding an object 30. The intermediate scaffold platform 100 consists of a plank 110 with two opposite long sides 112 and two opposite narrow sides 114. A decking element 120 is attached to at least one of the narrow sides, which extends the plank 110 beyond its length L in its longitudinal direction, for hanging or placing the intermediate scaffold platform 100 on an adjacent scaffold platform 210 or scaffold beam 230 of the scaffold 200.

[0016] Fig. Figure 2 shows plank 110 in a cross-sectional view. The plank is designed, for example, in the form of a standardized scaffold platform with a standard length L.

[0017] Fig. Figure 3 shows an embodiment in which the decking element 120 is formed with a first and a second leg 122, 124, wherein the two legs are bent at an angle of preferably 90° to each other. The first leg 122 is attached to the end face of one of the narrow sides 120 of the plank 110, e.g. by screwing or welding. The second leg 124 extends away from the plank 110, so that the surface of the intermediate scaffold floor 100 extends overall beyond the length of the plank 110.

[0018] According to another embodiment, not shown in the figures, the covering part 120 can be a simple sheet metal piece that is not bent but is attached to the surface of the plank 110 in the area of ​​one of its narrow sides 114, e.g. by screwing or welding. In this embodiment as well, the covering part 120 is attached to the plank in such a way that its free end projects beyond the plank 110 and extends it in its longitudinal direction.

[0019] In both embodiments, the screwing or welding ensures that the coating part is secured against unintentional loosening or displacement.

[0020] The covering part 120 may have grooves to increase its stiffness against bending.

[0021] Fig. Figure 4 shows a scaffold 200 according to the present invention for scaffolding an object 30, in particular one with a non-planar, here for example round, wall 32. The scaffold 200 here has, by way of example, at least one first and one second adjacent scaffold tower 250-1, 250-2, which, due to the roundness of the object 30, are positioned at an angle α>0° to each other. The scaffold towers are arranged at a mean clear distance A from each other and erected along the non-planar wall 32.

[0022] The distance A is preferably chosen such that a scaffold beam 230 and / or a toeboard, each with a standard length, can be installed between the scaffold towers on one longitudinal side, possibly on the longer and / or the shorter longitudinal side of the intermediate scaffold platform 100.

[0023] The first scaffold tower 250-1 has a first scaffold platform 210-1, and the second scaffold tower 250-2 has a second scaffold platform 210-2, with the two scaffold platforms being arranged at least approximately at the same height. Due to the angular arrangement and the distance between the scaffold towers 250-1 and 250-2, there is generally a trapezoidal gap 260 between the scaffold towers and between the first and second scaffold platforms 210-1 and 210-2. If the scaffold 200, as in Fig. As shown in Figure 4, if the scaffold 200 is erected against the outside of the unplaned, i.e., round or polygonal, wall 32, the short longitudinal side of the trapezoidal gap faces the wall. Conversely, if the scaffold 200 is placed against the inside of the unplaned wall, the long longitudinal side of the trapezoidal gap 260 faces the inside of the wall 32.

[0024] To create a continuous, as level as possible, working platform on the scaffold 200, the invention provides for filling or bridging this gap 260 with an intermediate scaffold floor 100. The intermediate scaffold floor 100 according to the invention is, as described above with reference to the Fig. The intermediate scaffold floor described in sections 1 to 3 is formed by 100.

[0025] In the scaffold 200 according to the invention, the distance between the two scaffold towers 250-1, 250-2, i.e. the mean width of the gap 260, is greater than the length L of the plank 110 of the intermediate scaffold floor 100, but less than the total length of the intermediate scaffold floor 100 according to the invention, i.e. the length of the plank 110 plus the longitudinal extent of the decking part 120 attached to at least one of its narrow sides 114.

[0026] This is a prerequisite so that – as provided for in the invention – the plank 110 of the intermediate scaffold platform 100 can be inserted into the trapezoidal gap 260. The plank 110 is then supported by the decking element 120, which is attached at least on one of its narrow sides 114, on the first scaffold platform 210-1 or on a crossbeam 230 of a scaffold frame 232 of the first scaffold tower 250-1.

[0027] By being inserted into the gap 260, the plank 110 is preferably completely enclosed by the gap and thus preferably flush with the adjacent scaffold platforms 210-1, 210-2; in this way, a working platform spanning the scaffold tower, at least largely level, is formed. Only the decking section 120 still protrudes above the level of the scaffold platforms. However, this is essentially negligible, so that the tripping hazard is largely minimized by the use of the intermediate scaffold platform 100 according to the invention.

[0028] The Fig. 5a, Fig. 5b illustrate this situation in a top view.

[0029] The decking section 120, with its free end not attached to the plank 110 (for example, with its second leg 124), is placed on the first scaffold platform 210-1 or on the crossbeam 230 of the scaffold 200, or suspended or hooked onto it. In all these cases, the free end can be attached or secured to the scaffold platform or crossbeam. The fastening can be in the form of a screw connection 130, a rivet connection, or a weld, etc. As in Fig. As can be seen in Figure 5, screw holes are provided in both the decking section 120 and the scaffold platform 210 for the insertion of screws for the detachable screw connection. The screw holes are preferably located at a distance d < 20 cm, preferably d < 10 cm, or even more preferably d < 5 cm from the free end of the decking section 120. The screw connection should be located as close as possible to the end / edge of the free end or the second leg of the decking section to minimize the risk of tripping or injury to a person using the scaffold.

[0030] At least one end face 114 of the plank 110 is formed at an arbitrary angle β to the longitudinal axis LB of the plank; and the end face of the covering part 120 facing the plank 110 is formed at such an angle γ to the longitudinal axis LA of the covering part 120, for example bent, that the angle sum β+γ=φ assumes a desired target value φtarget, with preferably φtarget=α / 2.

[0031] Fig. Figure 5a shows the arrangement with the intermediate scaffold floor 100 in a first embodiment, in which the angle γ=90° and β<90°.

[0032] Fig. Figure 5b shows the arrangement with the intermediate scaffold platform 100 in a second embodiment, in which the angle γ < 90° and β = 90°. In this case, the free end of the decking section is cut such that it extends perpendicular to the end of the longitudinal axis LA of the first scaffold platform 210-1.
