Scaffolding with openings and / or penetrations on the underside

Description

[0001] The present invention relates to a scaffolding floor designed as a hollow box floor. The hollow box floor is formed by two box-like profiles with openings and / or apertures on the floor side.

[0002] Scaffolding decks, in particular hollow box decks (or synonymously hollow box profile decks), have long been known in the art and are now the standard version of scaffolding decks for modular scaffolding. These scaffolding decks are usually rectangular in plan view of the load surface, with means for securing the scaffolding deck to a frame provided for erecting the scaffolding usually attached to the end faces (i.e., the short sides). These means can be designed, for example, as clamps or clips. US6105723 A discloses a scaffolding deck in the form of a hollow box deck.

[0003] A problem with the scaffolding decks known from the state of the art, however, is that water (e.g., rainwater and / or condensation) can penetrate the profiles forming the hollow box, particularly during extended storage and / or when assembled, and can remain there due to the lack of drainage. The penetrated water can contribute to lasting damage to the scaffolding decks, for example, through corrosion, but also, at sufficiently low temperatures, through the freezing of the water and the formation of ice. Irreparable damage to the scaffolding deck caused by water can thus occur, potentially significantly limiting the service life of the scaffolding deck.

[0004] The present invention therefore has the object of avoiding the disadvantages known from the prior art.

[0005] This problem is solved with a scaffolding floor having the features of patent claim 1. The dependent patent claims represent advantageous developments.

[0006] The present invention thus relates to a scaffolding floor in the form of a hollow box floor, which has a load-bearing surface on the upper side and two box-like profiles on the lower side, spaced apart from one another, which determine the height of the scaffolding floor. Furthermore, the scaffolding floor has means attached to two opposite ends of the load-bearing surface and / or the profiles for suspending and / or fastening the scaffolding floor to a frame. The openings and / or apertures are formed in the profiles on the underside.

[0007] The load-bearing surface of the scaffold deck represents the working surface of the scaffold deck, i.e., the area that can be walked on when the scaffold deck is installed. The box-shaped profiles are arranged on the underside of the load-bearing surface and enclose a hollow space. The two box-shaped profiles are spaced apart from each other and are positioned primarily on the outer sides of the scaffold deck.

[0008] According to the present invention, there are now openings and / or perforations on the underside of the profiles so that any water that has accumulated inside the profiles can drain out of the hollow space of the profiles.

[0009] The impairments known from the state of the art, i.e. damage caused by water accumulating in the profiles, can thus be avoided.

[0010] According to the invention, the load surface is continuous in the areas where the profiles are located on the underside and has no openings and / or perforations. This design thus prevents water from penetrating the profiles from above, thereby minimizing the problem of water damage discussed above. In the area where the profiles are spaced apart, the load surface can—but is not required—have perforations and / or openings, for example, in the form of a checkered plate, etc.

[0011] The openings and / or breakthroughs in the underside of the profiles are, independently of one another, round, oval, slot-shaped, n-sided, where n is an integer from 3-8, in particular 4 or 6.

[0012] It is further preferred that the scaffold floor has 2-50, preferably 4-20, in particular 6-10 openings and / or breakthroughs.

[0013] Furthermore, it is advantageous if the openings and / or breakthroughs are arranged centrally and / or at equal intervals relative to the length of the scaffolding floor.

[0014] This embodiment includes, for example, that there is one opening or breakthrough for each existing profile (so that the scaffolding floor comprises a total of two openings or breakthroughs), and these are arranged centrally along the length. This embodiment also includes the possibility of multiple breakthroughs being arranged per profile, which can be arranged centrally or evenly spaced along the length of the scaffolding floor.

[0015] Depending on the width of the respective profiles, the profile can have 1-5, preferably 1 to 3 openings and / or breakthroughs.

[0016] Preferably, openings and / or apertures are arranged symmetrically. This can, for example, involve a mirror-symmetrical design of the openings or apertures. The axis of symmetry can, for example, represent the central longitudinal axis and / or the central transverse axis of a rectangular scaffold floor.

[0017] The openings and / or apertures independently have a maximum diameter of 2 mm to 80 mm, preferably 6 mm to 12 mm. The maximum diameter is the diameter that represents the maximum dimension for an opening. For example, if the openings or apertures are square, the maximum diameter would be the diagonal through the square.

[0018] According to a further preferred embodiment, the openings and / or apertures can be designed as internal threads or have a threaded insert.

[0019] The openings and / or breakthroughs according to the present invention make it possible, for example, to fasten a load to the underside of the scaffolding floor. In the event that the openings and / or breakthroughs are designed without the previously described internal threads or threaded inserts, a load can be fastened, for example, by fastening a fastening means to or in the opening and / or breakthrough. In the simplest case, this can be done, for example, by inserting a hook into the opening and / or breakthrough, and using the hook to fasten a load to the underside of the scaffolding floor. Preferably, however, the fastening is done in such a way that a suitably designed fastening means engages in the opening and, after engaging in the opening, can be locked there, thus preventing the load from slipping out or sliding off.

[0020] In the event that the openings and / or breakthroughs described above have an internal thread and / or a threaded insert, the means for fastening the loads can be designed in a correspondingly complementary manner (for example an external thread and / or a thread compatible with the threaded insert), so that, for example, the means can be fastened to the underside of the scaffolding floor by screwing.

[0021] The scaffolding floor is preferably made of metal and / or plastics, in particular of sheet metal.

[0022] Particularly preferably, the scaffolding floor is formed in one piece from sheet metal. The profiles are formed, for example, by cold-forming the sheet metal.

[0023] In the event that the scaffold deck has been manufactured by cold forming as described above, the profiles resulting from the forming of the metal sheet may have a free end that is connected to the load-bearing surface of the scaffold deck, for example by riveting or welding.

[0024] It is also advantageous that the ratio of the spacing (i.e. the distance between the two profiles) to the total width of the scaffolding floor is 0.1-0.9, preferably 0.2-0.7, particularly preferably 0.3-0.5.

[0025] The present invention is explained in more detail with reference to the following figures, without limiting the invention to the specifically illustrated details.

[0026] Figure 1shows a scaffolding floor 1 according to the invention in the form of a hollow box floor. Shown is a cross-section illustrating the basic structure of the scaffolding floor 1. Visible is the load surface 2 arranged at the top, which represents the usable area of ​​the scaffolding floor (i.e., the accessible work surface). The scaffolding floor is formed from a single-piece metal sheet, which is brought into the corresponding shape by cold forming. Two profiles 3 (i.e., the hollow boxes) are formed on the underside of the load surface 2 by the deformation. A free end 5 of the metal sheet is guided back to the load surface 2 by deformation from the underside and can be connected to the load surface 2 there, for example, by means of rivets 6. The profiles 3 are arranged at a distance d from one another. The profiles 3 determine the height h of the scaffolding floor. The invention now provides that openings and / or breakthroughs are provided in the underside B of the profiles 3.

[0027] (in Figure 1 not shown) through which any water that may have accumulated in the hollow box 3 can drain away.

[0028] The Figures 2 to 8 now show specific embodiments of the invention, all of which are based on the principle described in Figure 1 The same reference numerals always refer to the same components, even if they are not explicitly repeated in the following description of the figures. The perspective view in the Figures 2-8 is chosen in such a way that a view of the underside B of the scaffolding floor 1 (cf. Figure 1 ) is shown.

[0029] Figure 2 now shows a first embodiment of a scaffolding floor according to the invention. Recognizable in Figure 2 are the two profiles 3 arranged at a distance d from each other, which protrude into the viewing plane (cf. Figure 1 ).

[0030] According to the invention, the profiles are additionally connected to each other by means of two webs S, which contributes to further stability and torsional rigidity of the scaffolding floor. A total of four openings or perforations are now provided in the area of ​​the respective profiles 3 on the underside. Additionally, openings or perforations 8 can be provided in the load surface 2, but only in the area of ​​the spacing d between the profiles 3. In the area of ​​the profiles 3 themselves, the load surface 2 has no perforations and / or openings. As can be seen from Figure 2 As can be seen, the openings or breakthroughs 4 are designed as elongated holes; each profile 3 has three openings and / or breakthroughs 4. The breakthroughs and / or openings 4 are arranged diagonally offset from one another.

[0031] Figure 3shows a further exemplary embodiment of a scaffolding floor 1 according to the present invention. In contrast to the Figure 2 In the embodiment shown, the breakthroughs and / or openings 4 are circular and are located centrally on the scaffold floor 1 shown.

[0032] Another embodiment of a scaffolding floor according to the present invention shows Figure 4 . The apertures and / or openings 4 arranged or introduced here are designed as rectangular slots and, with regard to their arrangement, are essentially as shown in Figure 4 shown trained.

[0033] Figure 5 shows a further variant of a scaffolding floor 1 according to the invention, which has identical openings and / or breakthroughs as in Figure 4 In contrast to the Figure 4 are the openings and / or breakthroughs in Figure 5 arranged at the same height.

[0034] In the variant according to Figure 6 Compared to the previous embodiments, the openings and / or apertures 4 are designed as relatively large apertures and / or openings. The openings and / or apertures are circular.

[0035] The embodiment according to Figure 7 has only one opening or breakthrough 4 in each of the profiles 3.

[0036] Figure 8 shows an enlarged section of a further embodiment of a hollow box floor 1 according to the invention. A perspective section of a single profile 3 is shown. Three breakthroughs or openings 4 can be seen, each of which has an internal thread 7 introduced therein.
