Definitions

  • Such a device for bending partially concreted, or fastened, individual reinforcing steels by approximately 90 degrees which is characterized in that two shaped pieces (1,6) are pivotally connected to one another via a bolt (15) serving as a pivot and bending axis, the one shaped piece (1) being adjustable in height a support (3) is guided and lockable and has a holder (17) open on one side for receiving the reinforcing steel (16) to be bent, the free space of which tangentially adjoins the bolt (15) that on the other fitting (6) there is a freely rotatable shaft (18) is arranged parallel to the bolt (15), further that on this fitting (6) a lever (7) is attached, which is intended to act as a power arm, while the distance between the pivot axis and shaft (18) as It is determined to act with a low load, and that the two molded parts (1, 6) can be swung apart so far that the shaft (18) completely traverses the extension of the free space formed by the holder (17).
  • the bending device essentially consists of the shaped piece 1, which is welded firmly to a square tube section 2, which is placed over a square tube 3 that fits into it and serves as a support 3.
  • the fitting 1 is thereby guided along the support 3 so as to be vertically displaceable.
  • the support 3 has a longitudinal slot through which a clamping screw 4 passes, which is held in a thread in the pipe section 2.
  • the screw 4 is provided with a lever handle 5, by means of which the screw 4 can be tightened, pressing on the opposite inner wall of the support and thereby clamping the pipe section 2 with the support 3.
  • the fitting 1 can therefore be locked at any height.
  • the second fitting 6 is pivotally connected to the fitting 1.
  • a lever 7 is fastened, which in the pivoted-out position of the fitting 6 is roughly normal height of a worker ends. It acts as a power arm when bending by the worker swiveling it towards itself.
  • FIG 2 the moldings 1 and 6 are shown on an enlarged scale. The illustration shows them in the swung-out position from the side.
  • the fitting 1 is box-shaped with the walls 11, 12 and 13, and the bottom 14. Between the walls 11 and 13, a bolt 15 is arranged, around which the reinforcing steel 16, which is shown in broken lines, is bent. The bolt 15 also serves as a pivot axis 15 and therefore passes through the fitting 6.
  • the thickness of the shaped piece 6 is dimensioned approximately half as large as the distance between the walls 11 and 13 of the shaped piece 1. So that the shaped piece 6 always bears against the wall 13, a shoulder on which the shaped piece 6 is in contact can be turned on the bolt 15 .
  • the bottom 14 and the wall 11 of the molded part 1 have recesses through which a holder 17 is formed, which encloses a free space which is intended to accommodate the reinforcing steel to be bent, as is indicated by the steel drawn in broken lines.
  • the shaped piece 6 pivotably articulated on the pin 15 has at some distance from the bolt 15 on a freely rotatable shaft 18 which runs parallel to the bolt 15.
  • This shaft 18 is advantageously ball-bearing.
  • the bolt 15 and the shaft 18 lie in such a way that the reinforcing steel to be bent can be inserted between them.
  • FIG. 3 now shows the two molded parts 1 and 6 in the swiveled-in position after the bending of the reinforcing steel, again drawn in broken lines, has taken place.
  • the shaft 18 rolls on the outer side of the bend of the steel, while on the inner side of the bend the steel is bent tightly around the bolt 15. Due to the rotatability of the shaft 18, the bending force is considerably reduced.
  • Figure 4 shows the two molded parts 1 and 6 from behind.
  • the bolt 15 is secured to the wall 13 of the fitting 1 by means of a snap ring 19.
  • the shaft 18 is fastened to the shaped piece 6 with a simple hexagon nut 20.
  • the slot 21 can be seen through which the clamping screw 4 is guided.
  • the lever handle 5 allows this screw 4 to be tightened effortlessly in order to lock the shaped piece 1 at any height on the support 3.
  • the device is now used as follows:
  • the desired distance from the exit of the steel to be bent to the bending point is set by means of the height adjustment of the molding 1. With the screw 4 this setting is locked by a handle on the handle lever 5. Now you take the device on the lever 7 and guide it to the reinforcing steel to be bent so that it comes to rest in the space formed by the holder 17. The support 3 now lies with its foot 22 vertically on the concrete base. Now you pull the lever 7 against you, whereby the lever 7 and the fitting 6 are pivoted about the pin 15.
  • the shaft 18 presses on the steel 16, which abuts on the bolt 15 on its other side.
  • the distance between the bolt 15 and the support point of the shaft 18 acts as a load arm.
  • the steel 16 is bent tightly around the bolt 15, while the shaft 18 rolls on the outer side of the bend of the steel 16.
  • the device is simply lifted away to the side, the lever 7 is pivoted back and the device is attached to the next steel.
