Definitions

  • the invention relates to a method for producing individual reinforcements for reinforced concrete surface structures, the reinforcement having at least one rod mat to be rolled out in one direction on the construction site with flexible strips running in the roll-out direction and rods fastened at right angles thereto and at least one second rod mat rolled out at right angles to the first rod mat , the bars of which lie loosely on the bars of the first bar mat which cross them, and the strips are fitted with the bars in a mat assembler and the mat is wound up into a roll.
  • ALLPLOT A CAD system from Nemetschek Programm System GmbH, Kunststoff, is known under the name ALLPLOT, which has a program that creates reinforcement lists and plans corresponding to the structural conditions of the building. In addition to the current member number, the file contains the diameter and length of the member. This program can be used for beam reinforcement, but not for tensile structures, because additional dimensions would have to be added here. This program accelerates the creation of reinforcement plans and lists. However, this program has no influence on the manufacture of the reinforcement itself.
  • Machines for the automatic production of reinforcement meshes are also known, e.g. from DE-A-36 15 460, but only standardized prefabricated ceilings can be produced with it. The control requirements for the production of individual reinforcement mats are missing.
  • the object of the invention is to create a new manufacturing method for individual reinforcements which, based on computational data of an extended structural analysis computer program, allows a fully automatic production of reinforcement meshes without any manual keyboard input of data and mechanical interventions.
  • the computer program available to the structural engineer e.g. The aforementioned ALLPLOT program only needs to be expanded in such a way that, in addition to the characteristic member data, it also determines the position data of the members per mat layer.
  • both the bar-specific and the mesh-specific values of all bars of the two lower and the two upper bar positions of the reinforcement are calculated. In this case, particularly in the case of surface structures, these values are often unequal on a limited area unit, the bars or bar groups being able to differ in length, thickness, longitudinal position and mutual distance.
  • the method according to the invention leads to a fully automatic production of the reinforcement mesh. Thanks to the individual production, a considerable reduction in the amount of structural steel is achieved.
  • the invention only requires two machines which operate under computer control, namely a bar former and a mat assembler. Both machines have a length equal to the maximum bar length of, for example, 15 m. A rod mat roll with a length of 15 m can be easily transported in road traffic. Wire coils or wire magazines for the bars are connected upstream of the bar former.
  • the rod generator ejects the rods selected in terms of length and diameter. These rods still have to be moved into the correct longitudinal position for the later rod mat. This can be done outside the staff. According to a variant of the invention, this longitudinal sliding device for the bars is assigned to the mat assembler.
  • the tapes are designed to be resilient. It has proven to be practical to use narrow steel strips, such as those used for packaging purposes. These have sufficient resilience.
  • the torque required for rolling out the mats on the construction site is provided according to the invention at least in part by the spring forces of the belts stored in the rod mat roll.
  • the spring strength of the tapes can be chosen so large that a slight push is sufficient to achieve a self-unrolling even with thick rod mat rolls.
  • Two possibilities for operating the assembler are within the scope of the invention.
  • One possibility is to drive the belts intermittently and to connect them to the bars during the idle periods.
  • the alternative is to let the tapes run continuously, the rod connecting members being moved with the tapes in a forward stroke during the joining process and performing their return stroke to the starting position after the joining process has ended.
  • the binding method for fastening the rods to the belts is selected according to one embodiment of the invention.
  • Wire is used as a binding agent.
  • a wire connector is arranged above the rod and below the band.
  • the wire connectors alternately shoot lengths of wire into one another's receiving funnel Wire connector. Then the rotating heads of the wire connectors are set in rotation, whereby the rod is tied to the tape.
  • the shooting-in process and the twisting process are independent of the rod diameter, so that the fastening time is the same for all rod diameters.
  • the rod mat roll is produced without a core, that is to say without a winding mandrel.
  • the entire rod mat roll can thus be processed at the construction site without any remaining objects, so that the transport of reusable return parts is saved.
  • the strips each have a leading section which is deformed into a winding ring in the winding station, so that the first reinforcing bar meets the circumferentially closed winding rings formed by the strips.
  • it is advisable to profile the tape feed sections for example to give them a V cross-section. Because of this deformation, there is the advantage of an additional form-fitting guide in the guide rollers or the guide bands of the winding station.
  • An alternative or cumulative feature according to the invention is that at least two wire rings are welded to the first rod of the rod mat before the winding process in the longitudinal distance, which act as a winding core during the subsequent winding of the mat and are simply broken off at the construction site.
  • the invention further relates to a machine for the production of bar mat rolls for the reinforcement of reinforced concrete surface structures, the bar mat to be wound up consisting of flexible parallel bands and bars held thereon, with a conveyor device which feeds the bars to a longitudinal sliding device, from which the bars arrive at a mat assembler , which has a number of tape supply rolls arranged at intervals, of which the tapes lead parallel to winding rolls of a winding device and the longitudinal sliding device has a roll bed, the rolls with axes parallel to each other and to the tapes each arranged between two belts and aligned along a line perpendicular to the belts and the rollers are at least approximately V-shaped in cross section and at least one of the rollers is coupled to a drive motor which forms the drive of the longitudinal sliding device.
  • Such a machine is known from the aforementioned US-A-3797193.
  • the bars are each arranged between lower and upper metal strips.
  • the upper metal bands are looped around the bars and welded to the lower bands. so that tape loops are formed in which the rods are slidably supported longitudinally.
  • the bars can therefore be shifted relative to each other at the construction site and even pulled out completely to take account of the given static conditions.
  • the mats produced in this way are therefore standard mats which are only adapted to individual requirements on the construction site. From the drawing of this document it can be seen that the rods are of equal length and are also positioned on the strips at equal intervals.
  • the individual adjustment of the reinforcement mat on the construction site is labor intensive, imprecise and involves the risk of reinforcement errors.
  • the machine according to the invention differs from this prior art in that a known static CAD program, which calculates the reinforcing bars of a bar mat with the initial data: sequence number, thickness and length from the static conditions of the structure, is expanded in that it determines the distance from the previous bar and the distance of a bar end from an imaginary mat edge as additional position data, that a transformation program in a computer converts the output data and the position data of the CAD program into a machine control program or several program modules that the longitudinal sliding device Computer-controlled rod former is connected upstream, which, depending on the program module containing the transformed output data, wire winding or wire magazine from Select wires of the appropriate diameter, unwind or pull the wires and, if necessary, cut them to predetermined lengths after straightening to form the bars, that the bars are successively shifted by means of a longitudinal sliding device into predetermined longitudinal positions with respect to the mat assembly, the drive of the longitudinal sliding device being controlled by the, at least part of the transformed position data-containing program module is controlled, and that the belts in the
  • the machine modules can, for example, have a width of 0.2 m up to a belt spacing of 1.50 m. All modules are the same and interchangeable.
  • the frames can be rigidly connected to one another by mechanical connecting links. In the same way, it is possible to mechanically connect the drive shafts of the tape feed devices of all modules to one another by connecting shafts by means of shaft couplings, so that a single drive motor is sufficient for all drive rollers of the tape feed device for the tapes. The same applies to the drive shafts of the winding device.
  • Each module is thus assigned to one of the tapes or a group of tapes.
  • the machine, generally designated 10, for producing wound reinforcement mats comprises a bar former 12 and a mat assembler 14.
  • the bar former 12 is preceded by a supply station in which a number of wire rolls 16 is rotatably arranged, on which the wires of different diameters for the reinforcement bars are wound.
  • Such rod formers are known and therefore do not need to be described in detail.
  • Program-controlled, one of the wires is drawn into the rod former 12, straightened and cut to length.
  • the bars 18 leave the bar former 12 via a slide and can be fed to the mat assembler 14 either directly or by means of a transfer device (not shown).
  • Thicker bars 18 are obtained from magazines with straight bar blanks, e.g. butt welded to length in the rod former.
  • the mat assembler has a number of parallel metal strips 20, which are guided from supply rolls 22 via deflection rolls 24 to winding devices 26.
  • Each band 20 is guided horizontally in the area of a rod connecting device 28 between two deflection rollers 24, a deflection roller located directly in front of the winding device 26 having been omitted in FIG. 1. All deflection rollers 24 located to the left of the connecting device 28 are aligned coaxially. The same applies to the right-hand deflection rollers, not shown.
  • a horizontal belt running plane is defined between this roller arrangement.
  • each band 20 comprises, for each band 20, a welding electrode 30 which can be driven up and down below the band running plane and a counter electrode 32 arranged above welding electrodes 30 on a continuous rail or a hinged bracket 64 (Figure 8).
  • a welding electrode 30 which can be driven up and down below the band running plane and a counter electrode 32 arranged above welding electrodes 30 on a continuous rail or a hinged bracket 64 (Figure 8).
  • Stop flaps 38 stop the rods 18 from sliding down on the roller bed.
  • At least one of the rollers 34 has a drive 40 which represents a longitudinal sliding device for the rod 18 in order to bring it into the desired position transversely to the longitudinal direction of the mat.
  • the lower welding electrodes 30 move upwards and press the rod 18 with the adjacent band sections of the bands 20 against the upper welding bar 32, so
  • the machine 10 In order to position the next bar 18 at the correct distance from the previous bar on the belts 20, the machine 10 has a belt feed device 42 which consists of a motor-driven roller which forms a narrow running gap for the belt 20 with the upper deflection roller 24.
  • the drive motor of the tape feed device 42 is a stepper motor which, under program control, brings about the required feed length of the tapes 20 and then stops the tapes.
  • the winding devices 26 keep the tapes 20 running from the feed device 42 sufficiently taut.
  • the feed device 42 thus acts as a brake.
  • each tape reel is supported in the winder 26 on a number of driven rollers.
  • the support rollers for the tape reel cause a higher peripheral speed than the tape speed controlled by the tape feed device 24, even with a small winding diameter of the tape reel.
  • the tape rolls thus slip through on the support rollers of the winding device 26.
  • a structural analysis computer program 44 generates a special file 45, corresponding to the respective static requirements of a tensile structure, with the corresponding values for the bending reinforcement.
  • This file 45 is formatted by a transformation program 46 in such a way that the required data 47 for several program modules result, which are analogous to a reinforcement plan.

  • the control data of the program module 50 are converted in the computer into control signals for the drives in the rod former 12 and transmitted to the rod former 12 via a cable 51.
  • Control signals are generated from the program data of the program modules 52, 54 in the same computer or in a computer assigned to the mat assembler 14, which control the longitudinal sliding drive 40 and the belt feed device 42 via lines 53, 55.
  • the welding bar 32 receives welding current over the line 57 as a function of the tape feed 42, which ensures that the downtimes of the tapes 20 are matched to the necessary welding time by appropriate control of the tape feed device 42, which is dependent on the diameter of the rods 18 and on average is about 4 seconds. Therefore, the electrodes of the welding bar 32 are supplied with control signals which contain the diameter data of the rods 18 and the position data from the Take the longitudinal sliding device 40 into account in order to activate only those welding electrodes at the actual crossing points of the rod with the strips.

  • Each machine module 15 has a plurality of tape supply rolls 22 which can be rotated next to one another on a common shaft, so that when a roll 22 is used up, the expired end of the tape can be mechanically connected to the start of the tape of the adjacent roll, for example by means of a hook-and-eye connection.
