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 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.
  • these values are often unequal on a limited unit area, 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 happen outside of the staff.
  • 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 on 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 shoot alternately Wire lengths in a receiving funnel of the other wire connector.
  • 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 machine is essentially characterized in that a rod longitudinal slide device with its own drive is provided for the rods, the drive of which can be controlled by control signals from a computer, that the individual structural positions of the bars determined in a structural analysis program are stored on a data carrier, from which the computer uses a transformation program to generate the control signals for driving the longitudinal sliding device, and that a bar positioning device, which in one variant can consist of a tape feed device of the mat assembler, also from Control signals of a computer can be controlled, which generates these control signals directly from the transformed arithmetic data of the structural analysis computer program, so that each rod can be positioned and attached to the belts with an individually calculated distance from the previous rod.
  • the machine modules can e.g. have a width of 0.2 to a band gap 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 meshes comprises a bar former 12 and a mat assembler 14.
  • the rod former 12 is preceded by a supply station in which a number of wire rolls 16 are 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 being 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 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, which corresponds 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 program data 47 are stored on a floppy disk 48.
  • Three program modules 50, 52, 54 are stored on diskette 48.
  • the program module 50 contains the rod-specific output data of the rods 18 to be fastened one after the other, namely the sequence, the length and the diameter of the respective rod 18.
  • the program module 52 contains position control data for the longitudinal positions of the successive rods 18 on the mat to be produced and the program module 54 the position control data for the distance of the respective bar from the previous bar.
  • 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 Consider the longitudinal slide device 40 in order to activate only those welding electrodes at the actual crossing points of the rod with the strips.
  • control signals for controlling the drives 12, 40 and 42 can also be generated by the program 46.
  • FIGS. 5-10 show another exemplary embodiment in which the mat assembler 14 is composed of a number of identical machine modules 15 which can be moved on wheels and which in the exemplary embodiment are close to one another.
  • Each machine module 15 processes one of the metal belts 20.
  • the bars 18 pass from the bar former 12 via individual slide rails 36 to the modular assembly machine 14.
  • a profiled roller 34 is arranged in each machine module 15. At least one of these rollers 34 has the longitudinal slide drive 40 or the longitudinal slide drives 40 of all machine modules 15 are electrically connected to one another, but could also be mechanically coupled and run synchronously.
  • Each machine module 15 has a plurality of tape supply rolls 22 that 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 adjacent roll, for example by a hook-and-eye connection.
  • the slide rails 36 have a number Locking levers 37, which form a buffer for a number of rods 18.
  • a storage compartment for a single rod 18 is formed between two locking levers 37.
  • Program-controlled, the locking levers 37 are briefly opened one after the other while the tape feed device 42 is being driven, so that the bottom bar 18 reaches the rollers 34 of the roller bed and the bars 18 lying above slide into the respective compartment below.
  • the rod longitudinal sliding device 40 can now bring the rod into the longitudinal position even before the strip feed 42 stops.
  • the belts 20 are briefly stopped and the rod connecting devices 28 come into action.
  • FIG. 10 these consist of two wire connector assemblies 80, 82.
  • the wire connector 80 has a built-in wire feeder, which coaxially shoots out a certain wire length 84 from a rotary head 86.
  • the wire front end comes into a deflection groove of the upper assembly 82, which bends the wire and presses it into a funnel-shaped hole 88 in the rotary head 86.
  • the rotary head 86 then rotates a few turns until the wire loop is firmly closed at the point of intersection between rod 18 and band 20 and shears off.
  • this can have two identical wire connection units on both sides of the strip running plane, which interact with one another. Each unit then shoots the same length of wire in a straight line into the narrowing hole of the turret of the opposite unit and the turrets of both units then rotate to cause an upper and a lower twist.
  • the rollers 34 with their drives 40 can be lowered below the running plane of the belts 20 by means of suitable actuating cylinders 60.
  • the rod 18 will then placed on the belts 20 and moved by these in the longitudinal direction of the mat.
  • the wire connection units 80, 82 can also be moved for the duration of the connection action with the tapes 20, for which purpose they are arranged pivotably about the axis 92. Thanks to time synchronization, the intermittent operation of the tape feed device can be replaced by a continuous operation.
  • the bar spacing is then controlled by the time lowering intervals of the rollers 34, so that the longitudinal sliding device 34, 40 also takes over the positioning function with its lifting / lowering drive.
  • the upper wire connection unit is fastened to a swivel arm 64 which engages over the winding station 26.
  • these units can also be connected to the lower wire connecting unit via a strap which bypasses the band 20.
  • the 8 has two bottom support rollers 66 for the rod mat roller 68, one of which is driven by a motor. Furthermore, an upper stationary guide roller 69 and a pivotable guide roller 70 are provided and the four rollers 66, 66, 69, 70 are wrapped in a belt loop 72 which surrounds the bar mat roller 68 over a considerable part of its circumference.
  • the pivot arm of the roller 70 is resiliently biased counterclockwise and takes the dashed position at the beginning of the winding process. The roller 70 then presses on the initial winding of the band 20 and holds it in positive engagement with a V-shaped groove 74 of the band loop 72.
  • each band 20 are also V-shaped by means of a profiling device, not shown, so that they are in the grooves 74 can intervene positively.
  • This deformation of the tape leader sections over a length equal to the initial one The winding diameter simultaneously stabilizes the rings, so that the individual band rings form a replacement for a winding core of the rod mat roll 68.
