Definitions

  • the invention is an end piece for a Distance pipe for guiding tension rods according to the preamble of claim 1
  • the formwork panels which are the outer boundary at Casting of concrete structures must, on the one hand, in a fixed distance to each other, which the Thickness of the wall determined.
  • the Shuttering panels the static pressure of the filled withstand liquid concrete mass.
  • tubular spacers or pipes between to use the shuttering panels which make it possible through the inside of the tube and corresponding holes in the Formwork panels to pass a tension rod.
  • the tension rod On the screws are placed on both ends of the tension rod, with which the two formwork panels against the Distance tube or on the ends of the spacer tube patch usually conical tails can be pressed.
  • spacer tubes For the creation of concrete walls, later with a Plaster are provided, more spacer tubes are known whose end pieces are part of the guide tubes and in the Wall remain. The production of such spacer tubes is cheaper, but do not settle for Use exposed concrete walls because their end pieces are insoluble are connected to the guide tube.
  • the invention is based on the object, an end piece for a spacer tube for the creation of To develop exposed concrete walls, on the one hand a Penetration of the liquid concrete mass in the Guide rod surrounding gap in the guide tube prevented and on the other hand, an easy detachment of the Ensures tail from the concrete wall surface.
  • the one- or two-part design of the spacer tube with the tails proves to be advantageous because at the production costs less, less Material use (plastic) for the production of the Distance pipe is needed and the dissolution of the Tails on the finished wall with or without little effort is possible.
  • Not by one rotationally symmetrical design of the cone-shaped Surface of the tails can be this by a Rotation with little effort from the end of the guide tube and detach or break away from the wall.
  • An inclination a predetermined breaking line with respect to a longitudinal axis of the Distance pipe vertical plane between the guide tube and the tail causes a helical and Consequently, an axial displacement of the tail, when the latter is set in rotation.
  • Reference numeral 1 is one of the prior art known spacer tube, comprising a substantially cylindrically shaped guide tube 3 and two to the arranged front ends of the guide tube 3 End pieces 5 denotes.
  • the end pieces 5 are in this known spacer tube 1 according to Figure 1 in the guide tube 3 inserted. They include for this purpose together with the conical jacket 7, the outside of the guide tube 3 to lie down, a cylindrical section 9.
  • the two End pieces 5 are inserted between two before insertion Shuttering plates 11 inserted into the guide tube 3. Merging the end pieces 5 with the guide tube. 3 can be done at the manufacturer or at the construction site. Usually, this assembly work is on site done.
  • the end pieces 5 can initially completely or only be partially inserted; but as soon as a tension rod 12 inserted into the guide tube 3 and with the front side attached nuts (not shown in Figure 1) the Shuttering panels 11 pressed against the spacer tube 1 be, slide the cylindrical portions 9 of End pieces 5 completely in the guide tube 3 a.
  • the end pieces 5 by a whole or interrupted circumferential fracture line with the Guide tube 3 connected.
  • the predetermined breaking lines can have different training and become explained in more detail below by way of examples.
  • the predetermined breaking line in the ends of the guide tube 3 comprises recesses or depressions 15 recessed from outside in the form of holes or slots which are mutually separated by narrow webs 17 in the circumferential direction.
  • the recesses 15 are not continuous, but closed on one side by a membrane-like skin 19 to the interior of the guide tube 3.
  • the skin 19 forms a barrier impermeable to the liquid concrete and has a thickness of, for example, 0.05 to 0.1 millimeter.
  • the recess 15 is circumferentially formed as a groove and it lacks the webs 17.
  • the groove which is laterally formed by Anbindekanten 20, in turn, has a skin or membrane-shaped base 19, which prevents the ingress of liquid concrete mass and the end piece 5 mechanically connects to the guide tube 3.
  • FIGS. 7a-7c A predetermined breaking line 13, which likewise comprises a skin or a membrane, is shown in FIGS. 7a-7c.
  • the recesses 15 are inclined there to the orientation of the circumferential predetermined breaking line 13 and mutually formed little overlapping.
  • FIG. 7b shows the spacer tube 1 or one of its ends 5 when a force F already acts on the end piece 5.
  • the slot-shaped recesses 15 are pressed together and the opposite side walls in the recesses 15 reach into mutual contact.
  • Figure 7c shows the end piece 5 after stripping the wall and after a slight rotation of the end piece 5 with respect to the guide tube 3.
  • another cylindrical or preferably slightly conically shaped section or region 23 is formed, the end of which is connected by a circumferential skin or a circumferential, very thin-walled region 25 to the inner wall 27 of the guide tube 3.
  • the outer diameter of the portion 23 at its end is d 0 and is slightly smaller than the inner diameter d 1 of the guide tube 3.
  • the end pieces 5 according to the embodiment in Figure 6a, 6b are formed similar to those in Figures 5a, 5b.
  • the end piece 5 or the region 23 adjoining the lower end thereof has a larger diameter d 3 than the outer diameter d 4 of the guide tube 3.
  • the connecting web or connection skin 25 is here connected to the outer wall of the guide tube 3 and the end piece 5 slides under the action of a force F on the guide tube 3 to a rotating or partially rotating stop 29. Due to the slightly conical design of the shell 31 of the region 23 and this end piece 5 can be easily pulled out of the latter after completion of the wall.
  • tabs 33 are additionally injection-molded on the outer end faces of the end pieces 5.
  • the tabs 33 may be connected on one side, as shown in Figure 8, or diagonally opposite at two points ( Figure 9) with the end piece 5.
  • the tabs 33 lie down when the spacer 1 is inserted into a formwork on the end faces of the end pieces 5 rich. After stripping the tabs 3 can be detected either on one side or on both sides with the fingers or with a screwdriver and at this the end pieces 5 are pulled axially out of the wall or rotated about the axis A.
  • depressions may be provided on the inside or on the inside of the end pieces, which allow the insertion of a screwdriver or fingernail (not shown).
  • a screwdriver or fingernail (not shown).
  • nail-like tips 41 which penetrate into the surfaces of the shuttering panels.
  • the conical surface of the end pieces 5 may have an oval cross-section, ie, the vertical and the horizontal diameter D 1 and D 2 are of different sizes (see Figure 10).
  • the difference between the diameters D 1 and D 2 can be within the range of 1 to 2 mm, so that the depression formed on the wall surface after removal of the end pieces 5 continues to appear optically circular.
  • Retaining means e.g. in the form of a bore 16 or a cam 18 ( Figure 4), formed at which a suitably shaped tool can detect the end piece 5.
  • the embodiment of the invention according to Figure 5a, 5b can not or only partially produce one piece, ie the guide tube 3 must be divided into two sections, each with an end piece 5, which can be pressure-tight connected to each other after spraying in the axial direction.
  • a spacer tube section of length L is shown on the left side with the end piece 5, the guide tube section 3 'and for example a sleeve 42.
  • the second half of the spacer tube with the guide tube 3 "turn one End piece 5 of the length L 1 visible on the guide tube sealing beads 43 may be formed, which allow a tight and permanent connection of the two guide tube sections 3 ', 3 ".
