Definitions

  • the invention is based on an air-layer anchor for masonry consisting of thin-walled metal, in particular steel, the anchor being designed flat at one end and having another rod-shaped length section which is formed by deformation of the anchor material.
  • the invention further relates to a manufacturing method for these anchors.
  • Such air-layer anchors are used to connect two-layer masonry, e.g. the connection of a shell made of sand-lime brick or aerated concrete on the one hand, and another masonry shell located on the outside, on the other hand, insulation boards can be arranged in the air layer between these two shells, which are arranged by the rod-shaped length section arranged in the air layer of the anchor are held. The free end of the rod-shaped section protrudes thereby into the outer shell, while the flat part of the anchor is held in the inner shell, for example in thin-bed mortar.
  • the rod-shaped length section is formed from a length section of the anchor blank, the width of which is considerably smaller than that of the flat length section.
  • the invention has for its object to practically prevent such losses by a special design of the anchor, in order to enable a practically waste-free manufacture of the anchor, without, however, impairing the functionality of the air-layer anchor.
  • the rod-shaped section of the armature is formed from a length section of the armature material (blank), the width of which corresponds to the flat section of the armature. Accordingly, the blank for the manufacture of the anchor can be of the same width over a length. This means that punching waste can be avoided. In order to increase the pull-out strength under this condition, an edge profiling of the flat section can also be used, which, however, must also be of special design in order to avoid waste. For this reason, the flat section has a flat, zigzag or undulating shape, in such a way that a zigzag or undulating cut is sufficient when punching from a material web to separate two successive anchors or blanks.
  • Air-layer anchors have the task of creating a connection between an inner shell 1 e.g. consisting of sand-lime bricks and an outer shell 2 e.g. to manufacture as a veneer. Between these two shells there is a cavity 3, which can be partially filled with a mat 4 made of an insulating material.
  • These air layer anchors consist of sheet steel with a wall thickness of about 0.5 mm and are manufactured by stamping or the like from a material web 5 according to FIG. 7. You point a rod-shaped length section 6 and a flat section 7, but the length section 6 is still divided into a central, substantially tubular section 8 and a profiled section 9. The section 7 passes through the inner shell 1, the tubular section 8 through the cavity 3 and the profiled section 9 through the outer shell 2.
  • the rod-shaped length section 6 is made from a length section of the strip-shaped blank 10 whose width corresponds to the width B of the flat section 7.
  • the diameter D according to FIG. 4 thus corresponds to the width B according to FIG. 5.
  • FIGS. 7 and 8 The resulting advantages can be seen in particular from FIGS. 7 and 8:
  • a material web 5 which has a row of holes 11 on both edges, which enables the material web 5 to be guided, but at the same time also determines the width of the blanks 10 on account of the hole spacing.
  • transverse cuts 12 are made from one hole to the opposite hole of the two rows of holes 11 by punching or the like.
  • the cutting length or the width of the material web are chosen so large that with each cut 12 two with the profiled Sections 9 facing anchors - as shown in Fig. 8 - can be manufactured. It goes without saying that with each cut only one anchor, but also three or more, or a multiple of two, anchors can be obtained.
  • the edges of the blanks 10 are first processed step by step to produce the rod-shaped longitudinal sections 6, in order to first form the longitudinal section 6 into a tubular shape according to FIG. 8 and then to form the section 9 by pressing in the tubular longitudinal section 6; this processing extends over the area S. It is advantageous if the tool used for this can be adjusted transversely to the material web 5 in the sense of the double arrow 20. As a result, lengths of length 8 of different lengths and consequently differently long anchors can be produced with simple means. With an eccentric tool for area S, two anchors of different lengths would then be created.
  • the flat sections 7 are formed, the design of which is still to be discussed.
  • the semicircles h are obtained from the rows of holes 11 in section 7, since the outer edges 7 'next to the rows of holes 11 are used.
  • the cuts 12 run in a slightly zigzag shape in the area of the right edge of the material web 5, whereas they otherwise run straight.
  • the shape of the cuts 12 is chosen so that the right one
  • the flat section 7 provided for the anchor is laterally delimited by zigzag-shaped edges, while all the remaining sections run straight or have straight side edges, which is also the case for the flat section 7 of the anchor shown on the left.
  • a V-section 14 consisting of two symmetrically arranged legs 13 of the same length has a deflection A which is approximately 2-4 mm, in particular 3 mm, with a total length of the section 7 of approximately 95 mm and a length of the legs 13 of about 25-35 mm.
  • the two side edges 15 of section 7 run parallel to each other. In pursuit of this idea, a wavy side edge 15 can also be used.
  • the profiled section 9 has a length of approximately 40 mm with a total length of the armature of approximately 210-300 mm.
  • the flat section 7 is provided with flat press-ins 19 which, according to FIG. 1, are directed toward the rod-shaped section & toward triangles 16, according to FIG. 2 interlocking angles 17 and also pointing towards section 8 3 are a plurality of wart-shaped press-in 18. It is important that all the press-ins 19 are mutually provided in such a way that they are directed once from top to bottom and from bottom to top. The pressings 19 are thus partly above and partly below the main plane determined by the flat section 7.
  • the press-in operations are preferably also arranged in such a way that an upward-directed press-in 19 follows.
  • this essentially results in a zigzag or undulating cross-sectional profile, which increases the form fit in the shell 1 in particular and is only produced by permanent deformation of the blank 10 and not by punched-out sections, which in turn lead to waste.
  • the suggestions mentioned in 1 and 2 can optionally be used on their own and also independently of the suggestion according to which the rod-shaped section 8 is formed from a length section which has a width B corresponding to the flat section.
  • the depth T of the press-in 19 to be mutually applied according to FIG. 6 corresponds approximately to one to three times the wall thickness of the anchor, but of course the intended dimensions of the inner shell 4 must be taken into account. It is also possible, if necessary, to leave the section 7 flat, even, that is to say to dispense with press-ins there, although the wavy or zigzag shape of the flat section 7 is then preferably selected.
