Definitions

  • the present inventioon relates to a self-elevating formwork installation with variable geometry for the execution of concrete sails, in particular of tall sails, these sails being produced by successive lifting of constant height, executed practically simultaneously, successively or in installments over the entire length of the structure until the desired height is obtained, this installation, this installation essentially comprising means for the temporary fication of working walkways on an underlying part already cast and hardened of the veil, means for shuttering the next lift on said underlying part, and lifting means capable of producing a self-raising of the assembly of walkways.
  • said fixing means comprise series of uprights extending substantially in vertical planes, these series being regularly spaced along the length of the web, said uprights being constituted on the one hand in the form of elements for holding formwork formwork, and on the other hand in the form of means for hooking mobile consoles, supporting said walkways.
  • FR-A-2 393 127 secondary uprights (beams 22) are provided between slides (16) for guiding the scaffolding carriage, but they are only used for formwork.
  • the slides (16) are only used for hooking the lifting carriages. Again, therefore, the hardware is not being used optimally.
  • DE-A-2 452 182 describes a technique together.
  • the purpose of the present invention is to provide an installation of the general type defined above and which allows better and faster than the installations known hitherto to erect thin sails of self-stabilized reinforced concrete, and in particular sails of great height with generally circular cross-section and with evolving geometry, as is the case in particular of large cooling towers in the form of hyperboloids of revolution.
  • Such an installation must therefore allow the formwork forming the mold capable of giving the veil the desired shape, and it must also allow the obtaining of means of support and self-elevation of the different scaffolds allowing access to all the parts of the work in progress, as well as the execution of all the necessary operations, namely reinforcement, formwork, concreting, as well as the control of all the movement mechanics.
  • an installation according to the invention will also aim to allow extremely precise adjustment of the different slopes of the veil to be produced, this by actuating means for adjusting the successive and relative inclinations of the different elements of the formwork.
  • the gangway assemblies will also have to adapt very simply to variations in the radius of curvature of the structure being worked on, this radius of curvature undergoing extremely large variations from the base to the top of the tower under construction. .
  • each secondary amount is inserted midway between two series of neighboring main uprights and in that said series of main uprights on one side of the web are offset, relative to the series of main uprights on the other side, by half the distance which, on the same face, separates two neighboring series, so that each secondary upright on one side of the veil is located opposite the upper upright of the corresponding series of main uprights located on the other side of the veil .
  • the secondary uprights will be able to cooperate effectively in the fixing of the shuttering elements, this concurrently with the upper main uprights of each series, in addition to allowing, like the latter, compensate for the tangential shrinkage of the formwork panels.
  • each secondary upright on one side of the veil is located opposite the main upper upright located on the other side of the veil, this will make it possible to reduce the difference between two consecutive supports of the formwork formwork , without multiplying the number of series of main amounts.
  • each series of main uprights comprises a certain number of uprights located in the same vertical plane, directly superimposed, articulated to each other, and each of which is inclined at an angle determined relative to the neighboring upright.
  • the main uprights will thus allow, in addition to the fixing of the formwork, the achievement of a precise radial adjustment thereof.
  • these main uprights may also be such that they can very easily compensate for the tangential shrinkage of the formwork panels, in addition to serving as guide rails and for hooking the mobile consoles .
  • An installation in accordance with the present invention may also be characterized in that it further comprises transfer means capable of being controlled after the execution of a casting, and of transferring the lower main upright of each of said series of uprights in one position located above and in alignment with the upper main upright of the series in question, position in which said transferred amount can then be fixed, at the desired inclination relative to the immediately underlying main upright, by means of appropriate adjustment means .
  • Each principal amount, and this in each of the series of principal amounts, can thus be used a large number of times by passing from a lower position in the series to a higher position in the same series when it is no longer useful at the bottom of series.
  • the means for adjusting the inclination of a main upright relative to the adjacent main upright can be produced in different ways, but, according to a particularly safe mode of implementation and allowing easy adjustment, these adjusting means being able to comprise on the one hand, at the two ends of said main uprights, a first device for adjusting the spacing with a screw or the like opposite to a transverse articulation means, and on the other hand a locking system or the like, suitable for blocking in relative inclination two adjacent main uprights, once they have been adjusted.
  • each secondary upright is fixed to the upper main upright which faces it by a set of fixing rods crossing the space provided for the next casting.
  • each of them being recoverable at each lift, it will be advantageous to provide that each of them is extended at its lower end by an articulated extension, whose inclination relative to the secondary upright itself is adjustable.
  • each console may include front main beams connected in an articulated manner, by support crosspieces, to rear secondary beams, said deformation adjustment means being constituted by adjustment stays, with screws or the like, extending diagonally between main and secondary beams.
  • Said support sleepers may include on the one hand the first sleepers, at bearings in principle non-deformable, these bearings allowing the passage of a gateway to the neighboring gateway of the same level, and second crosspieces supporting the gateways respectively at the same levels as said bearings, but arranged below the previous ones.
  • each console has three levels, two neighboring consoles therefore supporting three levels of gateways.
  • the consoles of an installation according to the invention may also be characterized in that they each comprise on the one hand a fixed bracket, disposed between the main beams and capable of bearing on the corresponding main upright, and of on the other hand a motorized mobile bracket, capable of being guided on the one hand between the main beams of the console, and on the other hand on said corresponding main upright and also to bear, in a determined location, on said main upright.
  • each console will cooperate to subject it to self-elevation, when it comes to moving from one lift to the next lift.
  • each console has an additional support device - roller or the like -, which is arranged at its lower part, so as to be able to bear directly on the web.
  • consoles also constitute essential elements of an installation in accordance with the invention, by making it possible to support the various circulation and working walkways while keeping them constantly horizontal, notwithstanding the different inclinations of the veil under development, in addition to the fact that, while serving as work cages, in particular for recovering the lower main upright and replacing it three lifts higher, they will make it possible to constitute an automatic climbing system with each new lift.
  • consoles will in principle support three work plans, namely, from top to bottom, a reinforcement and concreting plan, a formwork and formwork plan, and finally a climbing plan.
  • the gangway assemblies will, for their part, essentially fulfill their role as working and circulation floor, while adapting exactly and automatically, as regards their length, to the essentially variable spacings which will arise between two neighboring consoles, this due to the variable radius of curvature of the concrete veil, when it is a hyperboloid-shaped cooling tower.
  • each gangway comprises a lower gangway chassis and an upper gangway chassis, extending and resting between two neighboring consoles, these two chassis being free to slide relative to each other.
  • said lower gangway chassis may consist of a frame bearing on a console and of a drawbar bearing on the adjacent console, said drawbar being slidably connected to said frame, and in that said upper gangway chassis is mounted to bear on the one hand on the same console as said drawbar, and on the other hand also sliding on the lower gangway.
  • An installation in accordance with the present invention will be particularly well suited to the erection of such towers and this either by simultaneous or immediately successive lifting over the entire periphery of the structure, or by lifting carried out in sections.
  • the series of main uprights are generally referenced in 2 (FIGS. 1 and 2), these being designated respectively, in each series, and from top to bottom, 2 1 , 2 2 , 2 3 and 2 4 , taking into account that, in the example now described, the number of main uprights in each series 2 is four (see in particular Figures 3, 4 and 25).
  • the series 2 extend in vertical planes and are regularly spaced, in principle along the entire periphery of the web 1, and on each side thereof, their spacing, constant at a given level, but essentially variable depending on the height of the level considered, being of the order of several meters.
  • each series 2 the upper main upright 2 1 , to be used for the formwork of the next lift, is in turn connected and subject to the immediately underlying main upright 2 2 , thus, by means of two fixing rods 7 , than to a secondary upright 6 which makes it opposite, on the other side of the web 1.
  • Each secondary upright 6 is extended downwards by an articulated extension of the same width 6 ', thanks to which it can be fixed to the underlying part of hardened concrete 1, by another fixing and anchoring rod 3, which is used at the same time for the upper fixing of the corresponding main upright 2 2 ( Figure 4).
  • the fixing rods 7 and 3 ′ which may be threaded bars, have also been shown in FIG. 14, and their respective (elongated) holes for passage in the secondary upright 6 and its extension 6 ′ have been referenced 8 and 8 'in figure 13 (see also figure 15).
  • each secondary upright 6 is interposed halfway between two series of neighboring main uprights 2.
  • this arrangement is further characterized by the fact that said main upright series on one face of the web 1 are offset with respect to the series 2 of main uprights on the other side, by half the distance which, on the same face, separates two neighboring series, so that each secondary upright 6 on one side of the veil is located opposite the upper upright 2 1 of the series 2 of uprights main correspondent located on the other side of the veil 1.
  • the forms 9 are fixed by wedges wedged between bar latches shown diagrammatically at 10 and cross members 11 of the forms. These bar latches 10 pass through square tubes 12 welded externally to the main uprights 2 and visible in FIGS. 5 and 6.
  • the forms 9 are fixed by screw locks shown diagrammatically at 13 and likewise ensuring the desired fixing between the cross members 11 of the forms 9 and the secondary amounts 6.
  • the fixing nuts of these screw locks are shown diagrammatically in FIGS. 13 and 14, respectively at 14 for the secondary upright 6 and at 14 'for its extension 6'.
  • each main upright 2 1 ... 2 4 as regards its structure, comprises two guide wings 15 made of sheet metal folded in the shape of an "L”, connected transversely by a wide sheet metal 16, developed over the entire height and at the same time forming a compensation surface for the formwork and resistance box. At the top and bottom, the assembly is closed by two upturned sheets 17 in the plane of the guide rails 15 (see also Figures 7 and 8).
  • Each main upright is moreover equipped, at its upper end and at its lower end, with coupling means allowing its connection to a neighboring main upright, as already indicated above, as well as suitable adjustment means, allowing adjustment the slope of the upper principal amount relative to that of the immediately underlying principal amount.
  • the coupling means provided at the two ends of a main upright are complementary; they therefore appear in their entirety on a single amount, in particular in FIGS. 5 to 8.
  • These means comprise, at the lower part of each upright, a keel 18 capable of engaging in an upper opening 19 of the main cooperating upright and of being blocked therein, thanks to a key 20, the shape of which in section is visible on the Figure 9.
  • This key can be blocked between the bottom of the eyelet of the keel 18 and the upturned sheet 17 above, when the relative spacing adjustment between the two uprights has been achieved.
  • These uprights can indeed pivot relative to each other around a round bar 21 acting as a transverse articulation axis, which makes it possible to adjust the radial inclination of the upper main upright, and this of course at the appropriate time, in each of the 2 series of amounts.
  • the first spacing adjustment device comprises for this purpose, at one end of the upright, two pairs of gussets 22, each pair receiving the two ends of a screw 23 with spacing adjustment nut 24.
  • the two associated gussets 22 to an upright are connected to it in an articulated manner by removable pins 25, each mounted on a fixed yoke 26.
  • this device allows rapid separation and re-connection of the ends of two main uprights, when it is a question of passing a lower main upright above the other three, just as it also allows, conveniently and quickly, radially adjust the upper main upright that has just been set up.
  • FIGS. 5 to 7 there are also shown at 27, in FIGS. 5 to 7, holes (three per main upright) of passaga of support bracket pins, and at 28, plates for reinforcing the boxed structure of the uprights.
  • the secondary uprights 6 recoverable at each lifting, which essentially have the role of contributing to the formwork, without essential resistance function, and which are adjustable only in the radial plane, they consist of a U-shaped profile referenced at 29, welded flat on a wide bottom plate 30, which allows to obtain a certain tangential compensation of the formwork panels, which have a height which, to fix ideas, can be of the order of 1.50 m.
  • each secondary upright 6 is provided at its lower end with an extension 6 'allowing it to be subjected to the solid concrete of the underlying casting, to possibly compensate for the formwork, and finally to allow easy adjustment of the inclination of the amount 6 concerned with respect to said casting.
  • This extension 6 ' has a shape similar to that of the upright 6 and is pivotally connected to it by a simple thin sheet 31 welded inside the bottom sheet 30.
  • each secondary upright 6 is provided with 'a lifting ring 32, and, at its lower part, a second spacing adjustment device, comprising a screw 33.
  • Ce'vis is held by a head ring 34. and a through axis 35 in a yoke 36 of the secondary upright 6, and engages in a hole in a transverse sheet 37 of the extension 6 '.
  • Two nuts 38 engaged on the screw 33 enclose the sheet 37, and thus make it very easy to adjust the relative spacing between the upright 6 and its extension 6 '.
  • the extension 6 ′ may have a height of the order of 0.45 m.
  • consoles have been referenced globally at 39; they are also described in detail in FIGS. 17 and 18. They are each developed in the form of articulated parallelogram structures, which consist of two front main beams 40, connected in an articulated manner, by support crosspieces, to rear secondary beams 41.
  • the main beams 40 are connected by rigid crosspieces 40 'and the secondary beams 41 by braces 41', so as to constitute a rigid working cage which can only deform in the radial plane, this in function of the inclination of the web 1, and in an adjustable manner.
  • each console 39 comprises three pairs of first crosspieces 421, 422 and 42 3 situated on the two opposite sides of each console 39 and respectively at three non-deformable bearings 43 made of sheet metal welded on girders, fitted with railings 44 , these bearings making it possible to cross each console 39 at three different levels, to pass from one gangway to the next (see also Figures 1 and 2).
  • These bearings 43 are also each equipped with a passage hatch 45, allowing the passage of material, and in particular of the main uprights 2 1 ... 2 4 from the lower level (level 3) to the upper level (level 1).
  • Said support sleepers further comprise three second sleepers 461, 462 and 46 3 , arranged on one side of each console, also articulated to the side members 40 and 41 and situated at a level lower than that of the preceding ones.
  • These crosspieces serve as supports for the drawbar of the gangways which will be described below, the gangways being on one side supported on these second crosspieces and on three of the first crosspieces, and on the other side supported on the other three first sleepers.
  • each console 39 further extends an adjustment stay or screw strut 47 allowing, as is clearly visible by comparing Figures 17 and 18 , to deform appropriately the articulated parallelograms constituting the structure of the consoles, so that they are always parallel to the concrete veil 1 while retaining the horizontality of the walkways at each of their three levels.
  • These screw struts 47 are articulated in gussets 47 ′ of the main and secondary beams.
  • an additional support device with a roller or the like 48 has also been designated, which is disposed at the lower end of each console 39 and bears on the web 1, directly transmitting to it the normal compression forces.
  • Each console 39 finally comprises two organs essential to its operation, and in particular to its self-elevating function, namely a fixed bracket 49 mounted between the main beams 40, and a movable bracket 50, also visible in FIGS. 1 and 2 and capable of to move along these beams, above the fixed bracket 49. It is by means of this movable bracket 50 that each console 39 is guided along the series 2 of corresponding main uprights, the movable bracket being for this purpose provided with two rollers 51 bearing behind the wings of the main uprights, which wings therefore receive the normal forces of the movable bracket, other rollers ensuring its guidance between the main beams 40 of the console.
  • the movable bracket 50 is driven by a motor 52 bolted to a crosspiece 40 'connecting the two main beams 40 and driving in rotation a screw 53 axially fixed on the movable bracket.
