Definitions
- the invention relates to a method for manufacturing one of a thin-walled material, preferably Steel, existing air layer anchor for masonry, with the air layer anchor flat at one end is designed and another, the rest of the Air-layer anchor forming rod-shaped section has by the deformation of the anchor material is formed.
- the invention further relates to one made by this method Air layer anchor.
- Such air layer anchors are used to connect double-layer masonry e.g. the connection of a shell Lime sandstone or aerated concrete on the one hand and another, external masonry shell on the other hand, being in the Air layer between these two shells of insulation boards can be arranged by that in the air layer arranged rod-shaped longitudinal section of the anchor held are. The free end of the rod-shaped section protrudes thereby into the outer shell, while the flat held part of the anchor in the inner shell e.g. in Thin bed mortar is kept.
- Air-layer anchors are also known (GB-A-2259532), the plan at both ends in the manner of Letter W designed in such a way that individual anchors from a material web without Material waste due to scissors, punching or the like can be won.
- the W-shaped shape of the Air layer anchoring ends to a considerable extent the impaling of insulation boards for the air layer the creation of the masonry.
- Air-layer anchors for masonry are also known (EP-A-0183362), in which the two are in masonry to be arranged, kept essentially flat Anchor ends seen wavy in side view were formed during the air layer certain middle section in the plan zigzag runs and after completion of the Anchor blank is rotated by 90 ° so that it is in the assembled state of the anchor is arranged vertically.
- the invention has for its object a practically waste-free production of the beginning mentioned air layer anchor with a flat design End and another, the rest of the anchor to allow rod-shaped section without doing so however, the proper functioning of the air layer anchors impair and thus its tear resistance Reduce.
- the blank can be used for the manufacture of the anchor is the same over its length Width. This means that punching waste is avoided can be. Under this condition also the An edge profiling can also increase tear resistance of the flat section are used, but for reasons waste prevention should also be of special design got to. For this reason, the flat section is in the floor plan flat zigzag or wavy, so that when punching from a web of material a zigzag or wavy cut is enough to make two consecutive Separate anchors or blanks.
- Air layer anchors have the task of connecting between an inner shell 1 e.g. consisting of limestone and an outer shell 2 e.g. to manufacture as a veneer. There is a cavity 3 between these two shells, partially filled with a mat 4 made of an insulating material can be.
- These air layer anchors are made of sheet steel with a Wall thickness of about 0.5 mm and are stamped or the like. made of a material web 5 according to FIG. 7. You point a rod-shaped length section 6 and a flat one Section 7, but with the length section 6 still in a central, substantially tubular section 8 and a profiled section 9 is divided. Section 7 penetrates the inner shell 1, the tubular section 8 the cavity 3 and the profiled section 9 the outer Shell 2.
- To the anchor according to the invention is particularly low in waste To be able to produce stamping or the like from the material web 5, is the rod-shaped longitudinal section 6 due to the invention from a length section of the strip-shaped blank 10 manufactured, the width of the width B of the flat portion 7th corresponds.
- the diameter D according to FIG. 4 thus corresponds to that Width B according to FIG. 5.
- a material web 5 is used to manufacture the air layer anchors used, which has a row of holes 11 on both edges, the allows the material web 5 to be guided, but at the same time also determined the width of the blanks 10 based on the hole spacing. According to the hole spacing from a hole opposite hole of the two rows of holes 11 by punching or the like. Transversal cuts 12 are made, however the length of cut or the width of the material web is so great are chosen so that with each cut 12 two with the profiled sections 9 facing anchors - as in Fig. 8 shown - can be manufactured. It goes without saying that with each cut there may be only one anchor, but also three or more or a multiple of two each on anchors can be won.
- the edges of the Blanks 10 for producing the rod-shaped longitudinal sections 6 processed step by step, so that the length section 6 8 tubular and then by pressing of tubular length section 6 to form section 9; this processing extends over the area S. It is advantageous if the tool used for this The sense of the double arrow 20 is adjustable transversely to the material web 5 is. Length sections 8 of different lengths can thereby be and consequently anchors of different lengths with simple means be generated. With an eccentric tool for the Area S would then be two anchors of different lengths arise.
- Sections 7 formed, the design of which is still discussed becomes.
- the semicircles are in section 7 h obtained from the rows of holes 11, since the outer edges 7 'next to the rows of holes 11 can be used.
- the cuts 12 run in the Area of the right edge of the material web 5 weak zigzag while they are otherwise straight.
- the shape the section 12 is chosen so that the right one Anchor provided flat section 7 laterally from zigzag edges is limited while all the rest Sections run straight or straight Have side edges, which also applies to the flat section 7 of the anchor shown on the left is the case.
- the two side edges 15 of section 7 run here parallel to each other. Following this thought, one can wavy side edge 15 can be used.
- the profiled section 9 has a length of about 40 mm receives a total length of the anchor of approximately 21 0-300 mm.
- the flat section 7 receives flat pressings 19 which 1 directed towards the rod-shaped section 6 Triangles 16 and according to FIG. 2 interlocking, also for Section 8 angles 17 are. Important is doing that all the pressings 19 mutually in the way are provided that they go from top to bottom and from are directed upwards at the bottom.
- the pressings 19 lie thus partly above and partly below that by the flat section 7 certain main plane.
- the pressings are also arranged so that on top of one directed a downward pressing 19 follows. How 6, this essentially results in a zigzag or wavy cross-sectional profile that the Form fit in the shell 1 particularly increased and only by permanent deformation of the blank 10 and not by Die cuts are produced, which in turn lead to waste.
- the depth T of the mutually to be pressed-in 19 according to FIG. 6 about one to three times the wall thickness of the anchor corresponds, but of course to the the intended dimensions of the inner shell 4 is take .
- the section 7 flat it is possible, if necessary, to be left flat, i.e. there towards press-in waive, but then preferably the wave or zigzag shape of the flat section 7 is selected.
