Definitions

  • the present invention relates to a method for connecting two crossing bars, in particular for establishing a connection between two monier bars before casting with a concrete mass on a construction site, and to a device for carrying out the method according to the preambles of the independent method and device claims .
  • WO-A 8 404 772 (corresponds to EP-A-144 404) discloses a method according to the introductory part of the independent method claim.
  • the pliers arms are first opened and pushed over the crossover area of the rods to be connected, then the pliers arms are closed, after which the wire is advanced in a first channel running in the longitudinal direction of one of the pliers arms and then in a second channel running in the longitudinal direction of the other pliers arm transported and clamped in this.
  • the wire is in front of the Clamp cut off, after which the pliers are moved back while opening the arms so that the crossing area is outside the pliers.
  • the pliers then close again and perform a rotary movement, the wire ends being twisted.
  • the invention has for its object to eliminate the aforementioned useless times, continue to reduce the amount of energy to achieve the rotational movement and to run a method so that the effects of closely adjacent parts on the connection of the rods are kept to a large extent.
  • the part of the task with regard to reducing the energy expenditure to achieve the rotary movement is important insofar as the pliers-like tool is generally a tool to be carried on a construction site for which a grid feed-in of electrical current is not necessarily available. Also for security reasons, the current draw is from one Battery desirable, so that high protection against electrical contact voltage does not have to be driven.
  • the object is achieved in the procedural features of the independent method claim and in parallel to this in the device features of the independent device claim.
  • the mass to be set in rotary motion according to the invention is very much less than that in the prior art.
  • the diameter of the rotating part in the head is considerably smaller than the diameter of the gun arms, so that the momentum to be applied is considerably reduced. This automatically results in a substantial reduction in the drive power and a reduction in the run-down time of the tool once it has been turned. The times for establishing the connection of the two rods thus decrease considerably without the quality of the connection suffering as a result.
  • the stationary pliers form a protective distance when creating the rotating movement, so that disruptive influences of closely adjacent components, such as just made tube connections, have no influence on the tube connection to be operated.
  • FIGS. 1-10 of the drawings An exemplary embodiment of the invention is explained in more detail below with reference to FIGS. 1-10 of the drawings, the same reference numerals in the individual figures denoting the same details.
  • the tool according to the invention essentially consists of a plier-like tool which accommodates a pushing head in its interior.
  • the pliers-like tool and the push head are moved by one or more drive motors, which in turn are controlled by a control device.
  • the control device is actuated via at least one hand switch, the sequences of the individual process steps and movements of the elements of the tool are controlled by sensors, that is to say initiated, carried out and stopped for a certain time, here time measuring devices, rotation measuring devices, position sensors and the like being present are not further described below.
  • time measuring devices, rotation measuring devices, position sensors and the like being present are not further described below.
  • the entire tool, including motors and control device, as well as the power supply are accommodated in a portable housing, which is also not further described.
  • the tool according to the invention is used to connect reinforcement bars of a reinforced concrete structure to one another on a construction site or, as is known in technical terminology, to tie up.
  • the reinforcing bars or so-called monier bars are steel bars of up to 5.0 m in length, preferably of circular cross-section, the diameters of the bars being the same but also being able to vary. Rod joints of the same or different diameters can thus be produced.
  • the crossing bars are arranged perpendicular to one another and lie against one another. It can also happen that the bars cross at an angle other than 90 degrees and that they do not lie directly against one another when the formwork is being erected on the construction site, but at a distance from one another.
  • the toggle connections serve to secure the position of the bars relative to one another until the concrete enveloping them after casting has hardened. It goes without saying that the connection method according to the invention or the device independent thereof can also be used to connect other rods to one another, also for another purpose.
  • the so-called tubing tool for carrying out the tubing connection consists of a housing (not shown further here) with a handle, which carries one or more electric drive motors and optionally a battery or an electric accumulator.
  • a power supply unit that can do tools also be driven with low voltage, which brings considerable advantages for the operator in rough construction site operation with regard to electrical safety.
  • the housing ends in the direction of the toggle tool with a holding plate 4 , which preferably forms an end narrow side of the prismatic housing.
  • a hollow pin 5 which surrounds a hollow thrust pin 7 within its interior 6 , which surrounds a thrust rotary shaft 9 within its interior 8 .
  • a first actuating pin 10 and a second actuating pin 11 which are diametrically opposed to the hollow pin 5, project through the holding plate 4 and are guided in corresponding recesses.
  • a bearing bracket 16 is fastened by means of two pins 17 and 18 to the side 15 of the holding plate facing the pliers-like tool 14 .
  • the bearing bracket has at its two ends 19 and 20 a bearing bore 21 and 22 for a first and second tong arm 23 and 24 of the tong-like tool 14 .
  • the hollow thrust pin 7 On the side 15 of the holding plate 4 facing away from the interior 12 , the hollow thrust pin 7 carries a bearing head 25 which is arranged between the pins 17 and 18 .
  • the bearing head represents a prismatic body, which in turn has a central recess through which the thrust rotary shaft 9 engages.
  • the bearing head On two opposite sides, the bearing head has a groove 26 or 27 into which an extension 28 or 29 of the first and second tong arm 23 and 24 engages. It is thus possible, by translatory movement of the bearing head 25, to pivot the tong arms by means of the extensions 28 and 29 about their pivot points 21 and 22 .
  • the thrust rotary shaft 9 carries a thrust head 30 at its free end facing away from the interior 12 . This is connected to the thrust rotary shaft 9 that although it does undergo a translatory movement of the thrust rotary shaft 9 , it does not also take into account its possible rotational movement.
  • the push head 30 is assigned to the interior 31 , which is enclosed by the two tong arms 23 and 24 of the tong-like tool 14 .
  • the thrust head At its end facing away from the thrust rotary shaft 9, the thrust head has two recesses 32 and 33 which serve to receive one of the two crossing rods 1 and 2 facing the pliers.
  • the thrust rotary shaft 9 is assigned a contact (not shown further) of a control device, which has the effect that the motor for the pliers-like tool can only start when the thrust head 30 with one of its two recesses 32 and 33 against the crossing point 3 of the two connecting rods 1 and 2 is pressed. Releasing the pusher head from the bars causes the tool to stop.
  • the first tong-like arm 23 has a double-armed lever 34 , the fulcrum of which forms a bearing screw 35 .
  • the two ends of the lever are each provided with teeth 36 and 37 , the teeth 36 being associated with a shearing device 38 , which consists of a shear pin 39 - see FIG. 4 -.
  • the toothing 37 is associated with a toothing 40 of a further two-armed lever 41 which is rotatably mounted on the first tong arm 23 about a bearing pin 42 .
  • the lever arm of this double-armed lever facing away from the toothing 40 is assigned to the second actuating pin 11 . Due to the toothing, it is possible to pivot the shear pin 39 in its bearing bore of the first gun arm 23 by pushing the second actuating pin 11 back and forth so that it can be cut.
  • the first actuating pin 10 protrudes both through the holding plate 4 , but passes the holding bracket 16 , it rests on a lever arm of a third double-armed lever 43 , the function of which will be described later because it is on the in 1 of the second gun arm, which is not visible.
  • the double-armed lever 43 can be pivoted by advancing or retracting the first actuating pin 10 .
  • the first and the second tong arm basically each form a double-armed lever, of which one lever arm is formed by the extensions 28 and 29 , while the other lever arms make up the essentials of the tong-like tool 14 .
  • the ends of these lever arms 44 and 45 are each provided with a head 46 and 47 , which essentially have a slot 48 and 49 to be described later. Both partial slots complement each other to form a common slot.
  • the head 47 is assigned a clamping device 50 , which will be described later, of whose control only an elongated hole 51 and a control pin 52 are visible in FIG. 1.
  • FIG. 2 shows the pliers-like tool 14 from the side facing away from FIG. 1:
  • a single-armed lever 53 is pivotably mounted on the lever arm 45 of the pliers arm 24 by means of a bearing screw 54 , which connects the lever with a clamping pin 85 .
  • the end of the lever arm of the lever 53 engages with one lever arm 55 of the two-armed lever 43 , the other lever arm 56 of this two-armed lever is acted upon by the first actuating pin 10 .
  • a Screw 57 By means of a Screw 57 , a leaf spring 58 is attached to the lever arm 45 , which is a return device for the one-armed lever 53 and thus for the clamping device.
  • a holding pin 59 is provided at a distance and parallel to the thrust rotary shaft 9 , which is attached to the push head 30 and which passes through the holding plate 4 in the direction of the interior 12 .
  • the push pin 59 serves to allow a translatory movement of the push head 30 , on the other hand to prevent its rotational movement.
  • a helical compression spring 60 is arranged on the thrust head, through which the thrust rotary shaft 9 passes.
  • FIGS. 1 and 2 which show the starting point, must be used again.
  • the starting position is that the pliers arms 23 and 24 are opened by advancing the hollow pin 5 , so that the heads 46 and 47 have the maximum distance between themselves.
  • the thrust head 30 is retracted and thus the thrust rotary shaft 9 or the holding pin 59 .
  • In the first gun arm 23 there is a wire from a magazine roll, the beginning of which rests approximately in the area of the shear pin 39 .
  • the pincer-like tool 14 with the open pincer arms 23 and 24 is pushed over the crossing point 3 of two rods 1 and 2 now to be connected until one of the two rods 1 or 2 rests in one of the associated recesses 32 or 33 of the pushing head 30 .
  • the push head 30 is pressed in the direction of the holding plate 4 , to the extent that the already mentioned contact is triggered by tensioning the spring 60 between the pushing head 30 and the bearing head 25 .
  • the pusher head 30 is placed on the intersection 3 , the operator has already actuated the main switch on the housing. If the starting contact actuated by the thrust rotary shaft 9 or by the retaining pin 59 is now actuated, the motor can start in the interior of the housing.
  • the second actuating pin 11 is retracted, so that the shear pin 39 is rotated into the position shown in FIG. 4.
  • the scissors are now open.
  • the pliers are controlled, which is done by pulling back the hollow push pin 7 , it moves towards the holding plate 4 .
  • This position can now be seen in FIG. 3.
  • the tong arms are closed, so that the heads 46 and 47 are adjacent to one another except for a gap that is negligible in terms of production technology. It can be seen that the partial slots 48 and 49 complement one another to form an overall slot.
  • the crossing point 3 of the two rods 1 and 2 to be connected is located in the interior 31 , which is enclosed by the tong arms 23 and 24 .
  • the wire comes from a spool that is rotatably mounted on or in the housing.
  • the wire first passes through the holding plate 4 in a recess 64 and then passes into a wire channel 65 in the first pliers arm 23 .
  • the wire channel passes centrally through the entire forceps arm from a funnel-shaped inlet 66 to the outlet 67 below the slot 48 , below means that the outlet 67 is located between the slot 48 and the rods 1 and 2 .
  • the wire channel outlet 67 is aligned with a wire channel inlet 68 , which leads to a wire channel 69 in the second gun arm 24 , which also penetrates the entire gun arm in the longitudinal direction.
  • the latter Approximately in the area of the center of the wire channel 69 , the latter has a step 70 , at which the wire channel 69 widens, one ends here flexible shaft 71 , which leaves the outlet 72 of the wire channel 69 and leads the retaining plate 4 in a recess 73 into the interior 12 of the housing. If the pliers are closed, the first actuating pin 10 proceeds and opens the clamping device 85 , this position is shown in FIG. 4.
  • the beginning of the wire 74 moves from the open shear pin 39 through the space 75 between the two heads 46 and 47 into the inlet of the second wire channel 69 and meets the beginning 76 of the flexible shaft 71 in the area of the step 70 .
  • This impact causes a slight displacement of the flexible shaft 71 , which leads to a contact actuation in the area of the interior 12 and thus to a message to the controller that the wire feed has been carried out.
  • the first actuating pin 10 is withdrawn. If the first actuating pin 10 is retracted, the double-armed lever 43 pivots slightly counterclockwise, while the one-armed lever 53 rotates clockwise. Since it takes the pin 52 with it during this rotary movement, but the pin 52 is guided in an elongated hole 51 of the second pliers arm 24 , but the wire is still present in the second wire channel 69 , the pin 52 can practically only contact the wire. Accordingly, the clamp remains open since the clamping pin 85 cannot twist. The one-armed lever 53 is reset under the restoring action of the leaf spring 58 .
  • the pliers now again perform an opening movement, for example into a position corresponding to the illustration in FIG. 5. This is done by advancing the hollow push pin 7 . With this opening movement of the two Forceps arms, which leads to an enlargement of the intermediate space 75 , the wire is withdrawn from the wire channel 69 in the second forceps arm 24 again. The moment the wire start 74 passes the pin 52 , the clamping device can be closed because the leaf spring 58 can pivot the one-armed lever 53 further, the pin 52 can now move in the slot 51 . It reaches the end of the elongated hole 51 , which is located below the wire in FIG. 4. So that the clamping pin 85 is rotated so that the wire start 74 is clamped in the second pliers arm, in the area of its head. This position of the pin 52 can be seen in FIG. 5.
  • the thrust rotary shaft 9 is moved out of the housing together with the retaining pin 59 , so that the thrust head with its recesses 32 and 33 and the rods 1 and 2 stored there leaves the interior 31 of the pliers-like tool 14 .
  • the wire 63 wraps around the two rods 1 and 2 to be connected in the region of the side facing away from the tool.
  • the wire required for this purpose is made available by pulling it off the magazine and feeding it via the wire channel 65 in the first pliers arm 23 with a variable length. This state corresponds to that shown in FIG. 5.
  • the wire lies tightly around the intersection area and presses the bars 1 and 2 , which may still be spaced apart, directly against one another. Now the pliers close almost completely behind the crossing area - see illustration Fig. 6-.
  • the wire is also placed in the area of the intersection 3 of the two rods to be connected, which faces the pliers-like tool 14 .
  • FIG. 8 shows the push head 30 in a side view. It can be seen that the pusher head is U-shaped, resulting in two legs 77 and 78 and a bottom 79 , all of which are perpendicular to one another.
  • the holding pin 59 is welded to a leg 77 , the thrust rotary shaft 9 passes through the bottom 79 in the course of a recess and is rotatable relative to the thrust head 30 .
  • the thrust rotary shaft 9 carries a gripper 81 which has one or two gripper arms 82 and 83 .
  • the thrust rotary shaft 9 is mounted in a bearing disk 80 arranged on the bottom 79 .
  • a spacer ring 86 is located between the bearing disc and the gripper.
  • the gripper 81 is S-shaped, and when rotating, it can grip the wire ends of the wire 63 with one or both gripper arms. It can also be seen that between the legs 77 and 78 the heads 46 and 47 of the two tong arms 23 and 24 are enclosed, see FIGS. 7 and 9. It can also be seen that the slots 48 and 49 support the gripper 81 . Thus, the gripper arm or arms can rotate despite the pushing head 30 being stationary.
  • FIG. 6 To clarify the function of the elements shown in FIGS. 8-10, reference is now made again to FIG. 6.
  • the pliers are closed again, an overtravel spring being provided in the region of the drive of the pliers arms, so that an excessive feed movement of the motor can result in the gripper 81 laying against the periphery of the slots in the slots 48 and 49 .
  • the rotary movement of the gripper is possible.
  • the pliers close advantageously only to the extent that a largely friction-free movement of the gripper is possible.
  • the gun arms are closed behind the area of the crossing bars. Now both the first and the second actuating pins 10 and 11 move forward, so that on the one hand the clamp is released and on the other the Wire is cut off.
  • the wire is pressed into the recess of the gripper or the gripper arms 82 and 83 , for which purpose the smaller spacer ring is also useful.
  • the bearing disk 80 is a spacer between the heads 46 and 47 . This requires a specific position of the gripper arm or the gripper arms, which, however, can be approached by the control.
  • the motor begins to rotate the thrust rotary shaft 9 for a certain number of revolutions, so that the toggle joint 84 shown in FIG. 7 shortly before reaching its final state is formed.
  • the tube connection ends when the wire is pulled out of the ends of the wire channels with its two ends and leaves the gripper or the gripper arms.
  • connection process is ended and the connection is complete.
  • the device can be removed. Release of the main control contact by the operator causes the pliers-like tool to return to the starting position from the state shown in FIG. 7, that is to say the thrust rotary shaft 9 is retracted with the thrust head after the pliers arms have opened again.
  • the advantage of this procedure has the effect that the movement of the toggle tool to the next connection point can be used to bring the tool back into the starting position.
  • the wire rod 63 is part of the power supply line to the control, so that the tool cannot start if the wire wire is not present. This is advantageously designed such that the wire 63 must make electrical contact with the wall of the recess 64 in order to allow the process to take place. This serves to secure both the operator and the tool, since it ensures that there is no movement without wire feed.
