Definitions

  • the invention relates to a tool for applying a plaster layer, a fine plaster layer, a filler, an adhesive or a viscous resin according to the features of the preamble of claim 1.
  • tools such as surface fillers, scraper blades, smoothers, applicators, flats, squeegees, smoothing trowels and trowels have been used for many years when applying, filling and smoothing a layer of plaster, a layer of plaster, a filler, an adhesive or a viscous resin.
  • plastering of gypsum boards basic plastering is carried out regularly, in particular filling the butt joints of the gypsum boards with customary leveling compounds and the excess filler material subsequently being repelled.
  • a higher surface quality for example a standard filler
  • a subsequent filler is carried out until a smooth, ie smooth transition to the surrounding flat board surface is achieved.
  • the filler has the property of shrinking when drying or hardening, so that after drying, undesirable holes or dents can regularly be found on a previously smooth, flat filler surface.
  • each of these layers must be applied, repelled and sanded separately, a continuous flat surface can be achieved.
  • the initially very uneven plaster layer is usually stripped off with an application bar, whereupon the plaster layer, which is roughly aligned with this, is smoothed out with a surface trowel.
  • Cleaning material has the property of shrinking during drying or curing, so that after drying, undesired holes or dents can regularly be found on a previously smooth, flat cleaning material surface.
  • a surface filler used in this regard consists of an elongated steel sheet or a blade which is guided over the plaster layer. During the actual smoothing process, the blade used, for example made of sheet steel or stainless steel, is guided in alignment.
  • a spatula is known to be a hand tool, which consists of a handle and a long, flat, differently wide, rigid or flexible steel sheet.
  • putty In many craft activities, putty and the like. Materials with a pulpy consistency, for example putty, are applied, distributed and smoothed out.
  • the object of the invention is to overcome the disadvantages of the prior art and to provide such a tool for applying and smoothing a layer of plaster, a layer of fine plaster, a leveling compound, an adhesive or a viscous resin, which in particular involves the processing outlay and the use of materials when applying, Filling and smoothing a layer of plaster, a layer of fine plaster, a filler, an adhesive or a viscous resin is greatly reduced.
  • the object of the invention is achieved by a tool for applying a plaster layer, a fine plaster layer, a filler, an adhesive or a viscous resin with the features according to claim 1.
  • the blade 2 has a support side 2.1 with a recess 3, the flat outer edge of the support side 2.1 parallel to the longitudinal axis of the blade 2 and the recess 3 between the two edge parts 2.2; 2.3 the support side 2.1 is arranged and the maximum deviation of the contour 3.1 of the recess 3 with respect to the outer edge of the support side 2.1 has a value between 1.0 and 5 mm.
  • the solution according to the invention makes it possible in a simple manner that in the case where the tool according to the invention is above the respective joint, Cable slot, hole or dent a plaster layer, a fine plaster layer, a filler, an adhesive or a viscous resin was applied, corresponding to the dimension of the recess 3 results in an applied excess material, which is dimensioned such that after the usual shrinkage in this area of "Material excess" there are no holes or dents which extend below the level of the flat surroundings. Holes or dents above the level of the flat environment are processed by grinding in the usual way. Thus, grinding, ie no other work steps, as is known from the prior art, are required in order to achieve a flat surface or clean connections to the surrounding substrate. This regularly greatly reduces the additional work and material required up until now, particularly in the case of a 2 or 3-layer structure.
  • the angle of attack of the tool towards the work surface is selected so that the material to be applied is applied evenly to the surface.
  • a common angle of attack of the blade towards the work surface is approximately 30 ° to 90 °, although this can also vary in one operation.
  • the size and extent of the tool are selected so that, for example, joints, cable slots, holes and dents are adequately bridged.
  • the material thickness of the tool is a value from the range of 0.5 to 15mm.
  • the edge parts 2.2; 2.3 should be at least 20mm long.
  • the tool consists of common materials, such as metal, steel, Stainless steel, plastic, wood or composite materials.
  • Figure 1 shows a schematic view of the tool, namely a side view of a surface filler 6.
  • the surface filler 6 has a blade 2, the blade 2 having a support side 2.1 with a recess 3.
  • the flat outer edge of the support side 2.1 is arranged parallel to the longitudinal axis of the blade 2.
  • the recess 3 is in the middle between the two edge parts 2.2; 2.3 arranged on the support side 2.1.
  • the recess 3 is a closed contour 3.1 in Fig. 1 shown, this contour 3.1 has no edges or corners.
  • the recess 3 has a maximum width of 280 mm along the outer edge of the support side 2.1, the outer edge of the support side 2.1 having a width of 480mm.
  • the recess 3 has a symmetrical shape, namely the shape of a regular circle segment. This symmetry relates to the center line of the blade 2, which is arranged at right angles to the longitudinal axis of the blade 2.
  • the two edge parts 2.2; 2.3 which are of the same size and each have a flat section on the outer edge of the support side 2.1.
  • the blade 2 has a material thickness with a value of 0.5 to 3 mm in the area of the metallic working edge.
  • the blade 2 consists of a common metallic tool material, such as steel, stainless steel or iron.
  • the tool 1 has a grip element 4 and a blade holder 5.
  • the blade 2 can be detachably attached to the blade holder 5 in the usual way.
  • the depth of the blade 2 is approximately 80 mm in this embodiment.
  • the surface filler 6 is particularly suitable for use in drywall construction, in particular for gypsum boards, OSB boards and V 100 boards.
  • Figure 2 shows a schematic view of the tool, namely a side view of a scraper blade 7.
  • the scraper blade 7 has a blade 2, the blade 2 having a support side 2.1 with a recess 3.
  • the recess 3 is in the middle between the two edge parts 2.2; 2.3 arranged on the support side 2.1.
