Definitions

  • the invention relates to a scaffolding floor with hanging devices attached to opposite end sides.
  • Scaffolding floors have always been designed as solid wooden planks. In the past, they were simply cut off on the front and placed on the conductors or other supporting parts, so that when assembling and using them you could always see whether the ends had rotted or not and whether the load-bearing capacity was sufficient.
  • scaffold floors are used with metal frames made of steel and / or light metal and / or as a whole made of steel and / or light metal, so that the user is no longer used to paying attention to the rotting of scaffold floors.
  • solid wood scaffolding floors are made from solid wood boards lying next to one another with gaps or glued directly to one another, which are called block-glued solid wood boards.
  • Standard suspension devices are used in standardized scaffolding systems. As a rule, these contain hook-in claws on the front, which can be easily hooked into the U-profiles of the support elements that are open at the top and, above all, secure in them. Such hanging claws are attached directly to metal frames or scaffolding floors.
  • Sheet metal caps which are U-shaped, are used to attach suitable claws to solid wood boards bent sheet metal parts are formed with the same leg lengths and have the hooking claws on the vertical end web.
  • sheet metal caps are fastened to the ends of the solid wood boards with continuous rivets after they have been attached.
  • the sheet metal caps have previously been attached to the entire surface of the ends of the solid wood boards, possibly after reducing the thickness by the thickness of the legs.
  • the invention has for its object to make scaffolding floors made of solid wood available, the ends of which, even when absorbing moisture, allow the moisture to be released quickly and in which the end regions to which the attachment is made always remain clearly visible.
  • the invention provides the following features - Carrying element and running surface are formed from possibly block-glued solid wood boards; - Sheet metal caps with hook-on claws on the front are attached to the ends of the solid wood boards; - The sheet metal caps are U-shaped; - The sheet metal caps are attached to it with rivets extending through the solid wooden boards; - The sheet metal caps have ventilation openings in all surface areas of the upper leg and lower leg as well as the front web, in which they are free from fastening devices; - The ventilation openings have different size and / or shape corresponding to the available area.
  • the sheet metal caps have ventilation openings in all surface areas of the upper leg and lower leg as well as of the end web in which they are free of fastening devices. These can also be designed as profiled forms.
  • the sheet is dimensioned so that the load-bearing parts are concentrated on narrow strips or profiled remaining areas, while the Surfaces have openings as far as possible so that penetrated moisture can escape again quickly and the capillary action does not hold the moisture under large surface areas for a long time, which would promote the growth conditions for microorganisms and thus lead to the rotting of the solid wood ends.
  • the ventilation openings can have different sizes and / or shapes corresponding to the available area. So you can easily adapt to the conditions of the respective scaffolding construction.
  • each individual scaffold floor is about 32 cm wide, because then it will not become too heavy for frequent handling and because, on the other hand, two scaffold floors can be used side by side for the usual scaffold depths with a basic dimension of 70 cm and three next to each other Scaffolding floors the commonly used dimension of 1 m is reached, on the other hand, the scaffolding floors of this width can also be used alone or in groups next to each other as bracket planks.
  • the sheet metal caps for solid wood boards of different thicknesses are formed from the same blank with the same position of the holes as the edges, but with a different chamfer at a distance from the front web and therefore with their narrow design , fastening tabs of small width and of different widths that protrude far onto the wooden surface perforated edge area are designed. So you can easily adapt to the strength requirements of boards of different thicknesses with the same manufacturing tools for the respective width of the sheet metal cap.
  • the fastening of the sheet metal caps on the ends of the boards can be effected in different ways, depending on what makes the strength conditions and the processing effort seem reasonable.
  • the surfaces of the upper legs and, if applicable, the lower legs of the sheet metal caps can lie in the surface levels of the solid wood boards, so that indentations are worked into the solid wood boards at the end, or the inner contact surfaces of the upper legs and possibly the lower Let the legs of the sheet metal caps rest on the surfaces of the solid wooden boards that have just been passed through. Processing can be simplified and the risk of stumbling is not so great due to the sensible choice of thin sheet metal, but it can be reduced by deepening it.
  • the rivets for fastening the sheet metal caps are each formed with a round head on the top and with a recess on the bottom, so that when Stack the recesses of the rivets on the top of each scaffold floor to support the round ridges of the rivet heads of the scaffold floors underneath each, forming a ventilation space between the solid wooden boards.
  • the scaffolding floor 10 is formed, for example, with three block-glued strips of solid wood 11.1, 11.2 and 11.3, as shown in FIG. 1.
  • the width B is 32 cm. It is also possible to provide several loose, solid wood boards lying next to one another with small gaps if the sheet metal caps are designed accordingly.
  • the block-glued solid wood boards are made without layer gluing, as shown in Fig. 2.
  • Sheet metal caps 12.1 and 12.2 are attached to the ends 13.1 and 13.2 of the solid wood boards 11. These are, as can best be seen from FIG. 5, bent into U-shaped components and have an upper leg 14.1 and a lower leg 14.2 and a web 14.3. The latter forms the end face. In the area of its ends it carries two known hook-in claws 15.1 and 15.2 which are open at the bottom and which are welded on.
  • all surface areas of the sheet metal caps 12 that are not required for fastening are provided with ventilation openings 17. These are formed in staggered rows and / or with different sizes, depending on how the strength requirements require.
  • the areas 18.1 and 18.2 between the outer fastening legs 14.4 and 14.5 are punched out in a trapezoidal manner, while the middle region of the thighs 14.1 and lower legs 14.2 has remained between the fastening holes 16.2 and 16.3 in order to create stability here. For this purpose, it has a larger ventilation opening 17.
  • the webs 14.3 lying close to the ends of the solid wood boards 11 are also provided with ventilation openings 17 of different sizes between the hooking claws 15.1 and 15.2.
  • the paths for the moisture under the sheet metal surfaces to the ends or the ventilation openings are very short, so that moisture which has penetrated can escape well because of the pores in the wood and thus prevent rotting.
  • the wood can be observed through the ventilation openings 17.
  • Other hole shapes and hole designs as well as hole arrangements for the ventilation openings are also possible.
  • the sheet metal caps can also be provided with other hooking claws or be configured differently.
  • FIGS. 6 and 7 shows a very similar sheet metal cap 22. Parts of the same type are provided with the same reference numerals.
  • This sheet metal cap 22 is designed for wider scaffolding floors and therefore has a further hanging claw 15.3 in the middle.
  • here not only two outer fastening tabs 24.1 and 24.2 and a middle fastening leg area 24.3, but also intermediate fastening tabs 24.4 and 24.5 are formed on the upper legs 14.1 and lower legs 14.2 by punching out the trapezoidal areas 18.1 and 18.2 and by punching out further open areas 18.3 and 18.4.
  • the free length 26 of the fastening tabs 24.1 to 24.5 is chosen here — as can be seen from the drawings — to be substantially greater than in the first exemplary embodiment.
  • the area covered by the closed sheet metal is not appreciably larger, especially in relation to the entire wooden area, because significantly more and much larger ventilation openings 17 are provided.
  • both of the web 14.3 and of the central fastening leg area 24.3 there are no perforations, but instead cavities 27. These form sufficient cavities under the sheet metal that no capillary action can occur, so that the water is not held.
  • Such expressions 27 can also be designed in the form of company logos, names or markings for the material detection.
  • the upper legs 14.1 and the lower legs 14.2 lie smoothly with their inner bearing surfaces 21.1 and 21.2 on the surfaces 11.5 of the solid wood boards 11 which are not recessed at the ends.
  • Rivets 20 which extend through the fastening holes 16.1 to 16.6, are used for fastening. These are designed in the usual way as deformable metal bodies and each have a semicircular head 20.1. However, they are now not riveted to the underside with a semicircular head as before, but are equipped with a recess 20.2, which is located within an edge collar 20.3. This can be done easily and with good precision using suitable riveting tools.
  • the edge 20.4 of the recess 20.2 of an upper scaffold floor 10.2 support the rounded head 20.1 of the rivet of the scaffolding floor 10.1 below.
  • a large ventilation space 25 is created which allows the planks to dry out well.
  • the planks can also be stacked in an orderly manner and it is prevented that they come into contact with each other in some areas, so that water could collect in capital layers, as has been the case up to now and has led to rotting.
  • the semicircular heads 20.1 of the rivets are preferably so high that even in those cases in which the recesses 20.1 are not properly supported, the ventilation space 25 is still sufficient to avoid contact.
  • the ends of the fastening tabs 24.1 to 24.5 are rounded and thin, so that even when placed directly on the surface 11.4 without a depression, there are practically no stumbling blocks which hinder use.
  • the rounded heads 20.1 are also designed so that use is not hindered.
  • the scaffolding floor (10) consists of three solid wooden board strips (11.1; 11.2; 11.3), on the ends (13.1, 13.2) of which metal caps (12.1; 12.2) with hooking claws (15.1; 15.2) are attached. These have ventilation openings in all available surfaces (17). Stack rivets can be provided.
