Definitions

  • the present invention relates to a method for Production of a shear force mandrel consisting of a Steel core and a stainless steel jacket, as well as a Shear force mandrel manufactured using this process.
  • Shear force pins are used for horizontal connection and Power transmission between two components. Especially they are used in the expansion joint area of two neighboring Floor slabs and for laying stair pedestals with subsequent components.
  • the shear force mandrels store or on both sides of the expansion joint in corresponding bearing sleeves, as shown for example in EP-A-0'119 652. While the horizontal stretching movement must be allowed, the relative vertical movement can be prevented.
  • shear force mandrels are inevitable in the expansion joint area Subject to environmental conditions and can therefore corrode. Accordingly, many providers have switched to Shear force mandrels made entirely of high quality stainless steel to manufacture. Such shear force mandrels are preferably made of Chrome-nickel-molybdenum steel. This is extraordinary expensive and still capable in certain areas of application not to meet the security requirements. According to Recent discoveries tend to be made entirely of stainless steel manufactured rods for hydrogen embrittlement, which the Strength of the material reduced.
  • EP-A-0'119 652 shows a solution in which the mandrel consists of a core made of structural steel and a jacket tube made of stainless steel, which is pressed firmly onto the core.
  • the connection between two horizontal components, which are made by means of the shear force spikes is made, movements in the vertical direction practically prevent relative to each other.
  • optimal shear force mandrels of the latter type Condition not enough to meet.
  • the insertion a steel core in a stainless steel jacket a certain game. It is not for economic reasons possible, all components of a shear force connection to manufacture from calibrated components. And even then a play-free insertion of a core into a jacket technical impossible.
  • the outside dimension of the core and the The inside dimension of the jacket has a tolerance field.
  • points the outer dimensions of the jacket open and close a tolerance zone Such a tolerance zone also shows the inner dimension of the bearing sleeve in which the transverse force mandrel rests.
  • all of these tolerances can add up.
  • the so obtained Game results in a certain freedom of movement vertical direction between two horizontal components, which are connected to one another by means of transverse force mandrel connections are. The vibrations occurring in the structure therefore lead to vertical movements that lead to corresponding crack formation in the Guide the area of the transverse force mandrel connections.
  • Shear force mandrel either with a plastic plug can be closed or you can in the open jacket ends Insert and insert stainless steel rondelles weld.
  • a core 1 consisting of a steel rod and on the other hand a jacket 2 consisting of a stainless steel tube.
  • the core 1 can be made from a conventional structural steel. While the steps a) to c) to be described below mostly in appropriately equipped steelworks can take place subsequent steps d) to h) in each company that manufactures technical construction products. In the Steps a) to c) the semi-finished product is manufactured, so to speak, while the subsequent steps d) to h) die order-specific packaging.
  • a first step a the mentioned jacket is made stainless steel pipe according to known technology on one appropriately dimensioned steel rod 1, so that the steel rod then forms the core 1.
  • the core 1 itself acts as a calibration mandrel, whereby the desired approximate freedom of play is guaranteed.
  • step b) is purely schematic with 20 a corresponding calibration tool is shown.
  • the core 1 is drawn into the jacket 2 with commercially available bar material of several meters in length.
  • the extraordinarily accurate and at least approximately The steel core is pulled in without play using the addition a particularly suitable oil for this.
  • the so obtained, in c) Semi-finished product is sent to a plant for the Manufacturing of technical building products supplied.
  • the receiver operation of the semi-finished product is long Bar material 3 in corresponding bar sections 4 from step d). This is symbolically represented by the Saw blade 30.
  • the core 1 As indicated schematically under e), is now the core 1 by a distance a from the jacket 2 pressed out. This section 5 above will be followed severed flush with the end of the jacket, as shown by f). thanks to the core 1 can be used by pulling in the oil corresponding hydraulic machines from the jacket 2 press out without any remaining deformation were found.
  • FIG. 2 shows one manufactured according to the invention Shear force mandrel 10 shown. While half of the Shear force mandrel 10 closed with a plastic plug 7 is the other end with one in the open jacket end 6 inlaid stainless steel rondelle. For certain applications, especially in the interior of buildings plastic plug 7 very well. The required Tightness is achieved by appropriate sealing lips 8 on Plastic plug 7. For applications with particularly high Load capacity is one in the open jacket end 6 if possible insert dimensionally accurate Rondelle 9 made of stainless steel and this finally weld with the jacket 2. Depending on The desired tightness can only be welded at certain points or be designed as a circumferential weld seam 11. The here somewhat increased strength does not result so much through a load-bearing effect of the Rondelle 9, but rather by the absolutely fixed core 1 in the jacket 2. This results a high-strength sandwich construction.
  • the wall thickness of the jacket 2 becomes one certain relation to the diameter of the steel core 1 choose. In general, however, you can use surprisingly small wall thicknesses of the cloak can be decreased. Usual dimensions of the Wall thickness of the stainless steel tube from which the jacket 2 is between 0.4 and 5.0 mm. The relative brings small wall thickness of the casing 2 made of stainless steel of course again financial advantages.
