Definitions

  • the present invention relates to a method and an apparatus for forming metal frames for reinforced concrete.
  • the reinforcement frame of reinforced concrete pillars and beams is commonly produced by using metal frames formed by longitudinal iron rods connected by suitably spaced transverse stirrups.
  • the stirrups usually form a closed path, shaped for example like a quadrilateral, with overlapping ends.
  • the longitudinal rods are inserted in the profile formed by the stirrups, for example at the comers of said profile.
  • the method currently most widely used entails fitting the stirrups manually over the longitudinal rods, which are grouped and rested on suitable supports. After appropriately spacing the stirrups apart, and after tracing their position manually, some of the rods are tied to the upper portion of the stirrups. In the case, for example, of the stirrups having a quadrilateral profile, two longitudinal rods are tied at the comers of the upper horizontal side of the profile.
  • a considerable execution time is required in particular both by the step for positioning the stirrups and the longitudinal rods of the frame and by the step for fixing said rods to the stirrups.
  • Another method in use entails shaping panels made of electrowelded mesh.
  • the longitudinal rods are normally added to the structure thus formed and are fixed in the manner described above.
  • electrowelded mesh reduces the expenditure of labor for tying, but has the considerable limitation of being usable only for frames that have simple shapes and requires cutting the mesh panels to size, with a considerable waste of material and time.
  • European patent EP 0667195 discloses a method for forming metal frames for reinforced concrete which entails first of all the provision of an intermediate frame constituted by stirrups that have a closed profile, are arranged on suitably spaced parallel planes, and are fixed to at least two throwaway longitudinal rods, which are welded externally to the stirrups. A plurality of rods is then coupled to said lattice, and said rods are inserted within the stirrups and tied to at least some of said stirrups with known methods.
  • the apparatus that provides the cited solution is of the semiautomatic type and accordingly requires the use of labor.
  • the stirrups produced by the stirrup bending machine must be picked up manually by the assigned personnel and first inserted one at a time between the auxiliary rods and then pushed between the clamps of the welding elements of the machine in order to form the lattice.
  • the aim of the present invention is to solve the cited problems, by providing a method and an apparatus that allow to provide complete automation in the production of metal frames for reinforced concrete.
  • an object of the present invention is to provide a method that allows to provide metal frames for reinforced concrete with a considerable reduction of production times.
  • Another object of the invention is to provide an apparatus that allows to automate the production of metal frames for reinforced concrete with a structure that is simple in concept, safely reliable in operation, and versatile in use.
  • a method for forming metal frames for reinforced concrete characterized in that it comprises the steps of:
  • the reference numeral 1 generally designates the apparatus for forming metal frames for reinforced concrete according to the present invention.
  • the apparatus 1 is suitable to be associated with a conventional stirrup bending machine 2; conveniently, the stirrup bending machine 2 is mounted on a truck 3 that can move on a portion of track 4 that is arranged in series to the apparatus 1.
  • stirrup bending machine 2 has a working surface that is arranged vertically for the sake of convenience.
  • the apparatus 1 has a chassis 5 that is provided with the working elements of the apparatus and is arranged in front of the stirrup bending machine 2.
  • a longitudinally elongated platform 6 protrudes from the chassis 5 and forms a horizontal working surface.
  • An intermediate lattice 10 for the final forming of a frame is meant to form on the working surface of the platform 6 and is obtained, as specified hereinafter, by joining longitudinal auxiliary rods 11 externally to a series of stirrups 12.
  • the auxiliary rods 11 unwind from corresponding spools 7 which are arranged, preferably with a vertical axis, at the sides of the platform 6.
  • the platform 6 has a first input portion 16 that is suitable to be connected to the chassis 5; the first portion 16 of the platform 6 is conveniently provided with two longitudinal slots 17 that are suitable to allow the passage of the movable supports 77, which rigidly follow the longitudinal movement of the clamps (see Figures 7 and 10).
  • the chassis 5 and the platform 6 are adjustable in a vertical direction monolithically with each other, depending on the dimensions of the stirrups 12 being worked.
  • the chassis 5 and the platform are supported by pantograph-type lifting elements 8 and 9, which are actuated synchronously by means of a motor 13 that turns suitable screw elements 14, 14a and 15, 15a (see in particular Figures 3 and 4).
  • the chassis 5 is constituted by two lateral cross-members 18, which are connected at the base by two transverse longitudinal members 19.
  • the cross-members 18 are suitable to be fixed, by means of screw elements, to corresponding lateral portions of the first lifting element 8, whose width is proportionate to the width of the chassis 5.
  • Respective rail-type guides 20 are associated with the longitudinal members 19, and a plurality of trucks 21 and 22 can slide thereon; said trucks are mounted on wheels 23 and can be moved manually transversely to the line for forming the lattice 10. More precisely, the apparatus has two lateral trucks 21, which are mutually symmetrical, and a central truck 22.
  • the trucks 21, 22 are constituted by respective frames, each mounted on three wheels 23 per side, arranged with suitably offset axes 24, which slide within the rails 20.
  • the trucks 21 and 22 are further provided so that they can be blocked in the working position by way of respective braking elements 25 that are actuated pneumatically.
  • the trucks 21 and 22 support respective working heads 31 and 32 that are meant to weld the auxiliary rods 11 to the stirrups 12 and to draw the lattice 10 being formed.
  • the auxiliary rods 11 that unwind from the spools 7 are diverted on rollers 26, which are mounted so that they can rotate on vertical rods 27 that are fixed at the cross-members 18 of the chassis 5, and said rods then engage respective straightening elements 28 that are moved into position by the trucks 21 and 22 and are constituted by a series of rollers that have a vertical axis.
  • Corresponding portal-shaped frameworks 30 rise from the lateral trucks 21, and the lateral working heads 31 can move thereon in a vertical direction.
  • the lateral working heads 31 are mounted respectively on a cross-member 34, which is provided at its ends with sliders 35 that can slide on vertical guides 36 formed by the posts 37 of the portal-shaped framework 30.
  • the upper cross-member 38 of the portal-shaped framework 30 supports a motor element 39, which actuates a threaded shaft 40, that is rotatable about a vertical axis and is arranged so as to engage a female thread element 41 that is associated with the cross-member 34 ( Figure 6).
  • the lateral working heads 31 can be moved in a transverse direction by way of the movement of the corresponding trucks 21 and that the height of their position can be adjusted independently by way of the corresponding motor elements 39; the lateral working heads 31, moreover, can be rotated angularly at respective pivots 29.
  • the central working head 32 is instead fixed on the corresponding truck 22, and therefore its position can be adjusted only in a transverse direction.
  • the height of the central working head 32 is actually adjusted by way of the pantograph-type lifting elements 8 and 9, which move the chassis 5 and the platform 6 in a vertical direction, depending on the dimensions of the stirrups 12 being worked.
  • stirrups 12 have a fixed reference position on the apparatus, defined in practice by the cutting elements 90 of the stirrup bending machine 2, at the upper arm of the stirrups 12, while the position of the lower arm is determined accordingly by the dimensions of the stirrups 12 and is obtained through the adjustment of the height of the chassis 5 and of the platform 6 by virtue of the pantograph-type lifting elements 8 and 9.
  • the pantograph-like lifting elements 8 and 9 are adapted to move the chassis 5 and the platform 6 to a maximum lifting position, shown schematically by the dashed line 6a in Figure 1, which in practice coincides with said fixed reference position defined by the cutting elements 90 of the stirrup bending machine 2.
  • the apparatus actually allows to work stirrups constituted by linear bar segments, in order to provide with the longitudinal auxiliary rods 11 a mesh-like lattice or stirrups formed toward the upper part of the machine, i.e., with the reference of the zero plane in the lower part of the stirrup instead of in the upper region.
  • the central truck 22 in turn supports a gearmotor 42, which is suitable to actuate, by way of a suitable gear 43, a transverse splined shaft 44, which is supported so that it can rotate about a horizontal axis between the cross-members 18 of the chassis 5.
  • the horizontal splined shaft 44 is provided so as to transmit motion, by way of a corresponding bevel gear pair 45, to respective vertical shafts 46, which are supported rotatably by the lateral trucks 21 at a box 47; the vertical shafts 46 turn a gear 48, which is meant to actuate, as specified hereinafter, traction means that are associated with said lateral working heads 31.
  • An additional gear 49 is furthermore mounted on the horizontal splined shaft 44 and is meant to actuate, in turn, traction means that are associated with the central working head 32.
  • the position of the working heads 31 and 32 is adjusted by first moving said working heads 31 and 32 simultaneously in a vertical direction; once the correct position intended for the central working head 32 is reached, the lateral working heads 31 provided with individual adjustment movements are adjusted with respect to said central working head.
  • Each one of the working heads 31 and 32 is provided with respective means 50 for gripping and welding the auxiliary rods 11 and the stirrups 12 that are designed to form said intermediate lattice 10.
  • said grip and welding means 50 have a grip element 51, which is constituted by a beak 52 that is rigidly coupled to the stem 53 of a linear actuator 54 ( Figure 13).
  • the actuator 54 is fixed to a bracket 55 that is rigidly coupled to a stem 56 that is guided so that it can slide, in contrast with elastic means 57, through a sliding block 58, which is in turn rigidly coupled to the stem 60 of a second linear actuator 61, along an axis that is parallel to the axis of the first actuator 54.
  • the second actuator 61 is supported by a brace 63, which is provided with a pair of stems 64 for guiding the sliding block 58.
  • the bracket 55 is provided with a housing 65 for protecting the beak 52.
  • the bracket 55 is furthermore provided with a protruding roller 59, which is suitable to act as a locator on the front surface of the stirrup bending machine 2.
  • the brace 63 is fixed to the end of a pair of horizontal guiding shafts 66, which pass slidingly through a body 67. At the opposite end, the shafts 66 are fixed by means of a plate 68 to the stem 69 of a double-stroke actuator 70, which in practice is constituted by a first long-stroke jack 71 and by a second short-stroke jack 72, which are arranged in series.
  • the body 67 is fixed, by means of a flange 73, to a box-like enclosure 74, which acts as a support for a transformer element 75.
  • the enclosure 74 has a rack 76 rigidly coupled below it; said rack is suitable to mesh with a corresponding gear 48 and 49, which is turned by the gearmotor 42 by means of the splined shaft 44.
  • the illustrated case which relates to the central working head 32, shows the coupling of the rack 76 to the gear 49 mounted at the central truck 22.
  • welding means 80 which are supported in a cantilevered fashion and are constituted by movable welding units 81, which cooperate with fixed welding units 82 (see in particular Figures 22 and 23).
  • the movable welding units 81 are supported by an arm 83, which can be actuated by a linear actuator 84.
  • the fixed welding units 82 are mounted on a body 85, which is supported elastically on stems 86 in contrast with elastic means 87.
  • the method for forming metal frames for reinforced concrete by means of the described apparatus mainly entails forming a lattice 10 that is constituted by a plurality of stirrups 12 that have a closed or open profile, are arranged on suitably spaced parallel planes, and are mutually connected by one or more longitudinal auxiliary rods 11 welded to the outside of said stirrups 12.
  • the stirrups 12 form a substantially rectangular profile and are mutually connected by means of three auxiliary rods 11, which are arranged respectively on the lateral portions and on the lower portion of the stirrups 12 (see Figure 9).
  • the stirrups 12 can of course have any kind of shape, even a very complex one.
  • the auxiliary rods 11 are constituted by rods that have any cross-section, for example a narrow one, which is not defined by the designer of the structure. Preferably, the auxiliary rods 11 are thinner than the stirrups. Clearly, in addition to having a circular cross-section, the auxiliary rods 11 can also have a flattened shape or other similar shapes. It is further possible to provide on the auxiliary rods 11 suitable shaped portions or distinctive elements of any kind, for example a series of suitably spaced recesses.
  • auxiliary rods 11 that unwind from the spools 7 engage respectively the straightening elements 28, which are carried in an adjustable position by the trucks 21 and 22 of the apparatus, and are then welded by the corresponding working heads 31 and 32 to the stirrups 12 provided by the stirrup bending machine 2.
  • the stirrups 12 are picked up automatically on the stirrup bending machine 2, which for this purpose is arranged, so that its working surface is preferably vertical, in front of the described apparatus, at an input region E thereof ( Figure 1).
  • the apparatus grips the stirrup 12 to be picked up by means of the grip elements 51 of the working heads 31 and 32 before the cutting of said stirrup 12 from the material in bar or coil form from which it is obtained by bending.
  • the grip elements 51 are moved by the double-stroke actuator 70 into a grip position that is formed by the abutment of the roller 59 on the stirrup bending machine 2, with the beak 52 open on a corresponding portion of the stirrup 12 ( Figure 14).
  • stirrup 12 After the stirrup 12 has been gripped by the grip elements 51, said stirrup 12 is cut by the conventional cutting elements 90 of the stirrup bending machine 2 ( Figure 5).
  • the stirrup 12 gripped by the grip elements 51 is then moved in a longitudinal direction by virtue of the actuation of the corresponding double-stroke actuators 70, until a preset working position (Figure 16) is reached.
  • the welding means 80 preset in said working position, are activated.
  • the movable welding units 81 are lifted by the actuator 84 ( Figure 17), followed by a suitable retraction stroke of the grip elements 51 under the control of the second short-stroke jack 72 of the actuator 70, in order to place the stirrup 12 at said movable welding units 81 ( Figure 18).
  • This is followed by the fastening of said stirrup 12 between the welding units 81 and 82, for example of the resistance type, and by the release of the stirrup 12 on the part of the grip elements 51, in order to weld externally to said stirrup the auxiliary rod 11 simultaneously fed in a longitudinal direction (Figure 19).
  • stirrups 12 is welded at the chosen distance to the auxiliary rods 11 so as to form the lattice 10.
  • the mutual distance between the stirrups 12 is not necessarily constant, but can be changed along the longitudinal extension of the lattice 10, according to the various requirements.
  • auxiliary rods 11 are preferably narrower than the stirrups 12, said stirrups are not affected by the welding step that instead causes the local melting only of the auxiliary rods 11.
  • the resulting lattice 10 can be used to provide the metallic frame, in particular by coupling suitable rods 12 inside the stirrups 12. More specifically, the rods used to form the frames are constituted by longitudinal supporting bars, whose characteristics are determined by the designer of the structure according to calculations in accordance with the applicable standards. The supporting bars are fixed to at least some of the stirrups 12 of the lattice 10, for example by means of conventional bindings.
  • stirrups 12 are instead already fixed and spaced by virtue of the welding with the auxiliary rods 11 of the lattice 10 and therefore bindings are needed only to keep the longitudinal bars in position.
  • the method and the apparatus according to the invention allow to provide complete automation in the production of intermediate lattices for forming metal frames for reinforced concrete, eliminating the need for the operator to pick up the stirrups from the stirrup bending machine, carry them and insert them manually and individually in the assembly apparatus by means of a second operator.
  • the apparatus according to the invention is free at the front input region E, so that the stirrups 12 can be picked up at the front.
  • the apparatus can therefore adapt to any kind of stirrup bending machine without requiring structural modifications.
  • the straightening elements 28 supported by the trucks 21 and 22 are arranged in an oblique position that converges toward the output with respect to the lattice 10 being formed, so as to form, with the corresponding auxiliary rods 11, a sort of funnel.
  • This allows to have enough free space to introduce the stirrup 12 at the front, without interfering with said straightening units 28 and without the risk of any scraping of the stirrup 12 against the rods 11.
  • the auxiliary rods 11 in fact assume a path that is substantially tangent to the lattice 10 only after they have been welded.
  • stirrups 12 are loaded manually or by way of automatic loading means of a different type, for particular production requirements.
  • One prerogative of the method and apparatus according to the invention is constituted by the fact that the advancement of the lattice 10 being formed is provided by the welding elements 80 that weld the stirrups 12 to the auxiliary rods 11. It is therefore possible to weld the stirrups 12, at least partially, during said step for the advancement of the lattice 10, with an overlap of the two steps that obviously leads to a substantial reduction in downtimes and therefore to a significant time saving.
  • auxiliary rods 11 can be joined to the stirrups 12 through any type of coupling, particularly through any welding method.
  • the rods 11 can be located on any side of the stirrups 12, and there may be even more than one rod per side, according to the requirements.
  • the method for moving the frame being formed may also be any, by traction or pushing, for example by using traction wheels integrated in the straightening unit.
  • the materials used may be any according to requirements.
