Definitions

  • the present invention relates to a scaffolding board made of at least two interconnected wooden layers, between which a flexible material is slackly arranged, which consists of several elongated inserts running in the longitudinal direction of the scaffolding board and is connected in places to the wooden layers, the inserts being dimensioned accordingly serve to absorb the remaining energy in the event of a complete breakage of the wood layers caused by an impact of an object on the scaffolding board by the corresponding impact energy, in order to prevent the scaffolding board from completely breaking through.
  • Scaffolding boards are usually placed on the corresponding supports of a tubular scaffold at the area of their respective ends. If an object or a worker falls on a scaffolding board from a certain height during construction and the scaffolding board breaks, the two fragments, which are now only carried at one end, form actual trap doors so that the falling object or the falling one Person without a way of stopping the case falls even further. This has often caused accidents, on the one hand, obviously, in that a falling person continues to fall through the broken board and, on the other hand, that a broken object injures a person located below.
  • a known scaffolding board of this type (DE-OS 21 01 671) it is therefore provided that substantially parallel to the board and essentially of the same size on the fastening means and between the framework of the supporting beams and the covering Plate is a piece of flexible material in the form of a mesh made of plastic.
  • the scaffolding board as such is formed from the framework mentioned by the supporting beam and this framework is also covered by a plate.
  • the aforementioned network is arranged between the framework and one of these cover plates. Due to its structure, this previously known scaffold plate has a large number of hollow chambers, which experience has shown that it cannot be sealed.
  • the aim of the invention is therefore to remedy these disadvantages.
  • the wooden layers are glued to one another along the common contact surfaces and the inserts consist of tape-like strips. Thanks to the proposal according to the invention, a weatherproof scaffolding board is obtained.
  • load-bearing material strips can be integrated between the wooden layers.
  • the previously known forms for such flexible strips of material are not considered to be expedient, since in the former case the large-area connection cannot be guaranteed, because the net would form a continuous separating layer between the wooden layers, whereas wires, which are relatively thin in order to accommodate them between layers of wood may not be able to offer the desired security.
  • the scaffolding board shown in section in FIG. 1 has three wooden layers glued to one another, an upper layer 1, a middle layer 2 and a lower layer 3.
  • the scaffolding board is thus constructed in a known manner from a plurality of wooden strips running one above the other.
  • the contact area between the upper layer 1 and the middle layer 2 is indicated by the reference number 4, and the contact area between the middle layer 2 and the lower layer 3 by the reference number 5.
  • a fabric strip is placed on the respective side of the corresponding wooden layers to be glued in the example shown.
  • the layers are then glued to one another, pressure possibly being applied, so that the scaffolding board is provided with two strip sections each running more or less parallel in the longitudinal direction of the board.
  • the insert can consist of a fabric strip, can be a plastic strip, steel tape, wire rope, plastic rope, a plastic string or a cord.
  • One or more strip, band, rope, etc. sections running more or less parallel to one another can be inserted.
  • Figure 2 shows an embodiment with two parallel such elongated inserts, each of which ends flush with the end faces of the scaffolding board. Versions are also provided in which these inserts are connected at both ends via a loop, ie that, for. B. an endless belt is inserted in such a stretched state that it has two approximately parallel, rectilinear sections, which at each end of the board are connected to each other with a loop section.
  • the scaffolding board is composed of more than two layers of wood, it is not necessary for an insert, ie, fabric strips, to be inserted into each contact surface of adjacent layers of wood. If the scaffolding board consists of e.g. B.
  • fabric strips can only be present at the contact surfaces between the two outermost and the layers immediately below, or, alternatively, only at the innermost contact surface between the two inner wood layers.
  • the fabric strip for example, must be inserted in a slack state so that it can absorb tensile forces due to a small stretch if the board breaks. The same applies to all embodiments. If the respective insert is tensioned and also connected to the scaffolding board along its length without interruption, the desired safety effect cannot occur.
  • the object is now stopped by the insert, i.e. the fabric strips. Since these have been inserted limply in the scaffolding board, they have not yet been subjected to any force until they come into contact with the object. You only need to use the remaining energy after breaking through the wood. B. in the form of a tensile load. So you do not have to be so strong that they have to absorb the entire impact energy. There is thus a two-stage energy destruction. Since the two pieces of board separated by the break can no longer swing down, the object obviously cannot fall any further down and cause any damage or injuries further down.
