    CONCRETE SYSTEM FOR CONCRETE SUPPORTS HOLES IN HEIGHT AND PROCEDURE FOR THE EXECUTION OF CONCRETE SUPPORTS HOLES IN HEIGHT
    DESCRIPTION
    OBJECT OF THE INVENTION
    The present invention relates to a formwork system for hollow concrete supports in height and to the procedure for the execution of hollow concrete supports in height that can be implemented with said system.
    SECTOR OF THE TECHNIQUE
    The sector of the technique in which the invention is framed is the sector of the construction technique, and more specifically that of formwork and construction systems for the execution of concrete supports in height, such as batteries, pillar shafts, chimneys, central cores, supports, etc.
    BACKGROUND OF THE INVENTION
    For the execution of concrete supports in height (piles, chimneys, central cores, etc.), it is usual to use formwork that allows the execution of the total height in different phases, so that with the same formwork used repeatedly It can execute the structure in different sections or tonados, sections limited both by the height of the ferralla and by the pouring height of the concrete of the tongada. These formwork are rising successively, and each new formwork arrangement is above -or climbs- over the previously made toning.
    A classic classification of these formwork for hollow concrete supports in height, depending on the number of tonings and the height of the support to be executed, ordered from least to greatest complexity, would be:
    1-Stacking formwork, consisting of a formwork comprising a mold

    interior and an external mold, and that is supported by support platforms to execute each of the tunes, lowering the complete formwork to the ground at each laying. Its use is planned for few tonings in height or with little pace of execution (for example, in walls that have been forged on the edge of buildings).
    2.-Climbing formwork, which consists of a formwork that moves in solidarity to the climbing platform, so that with a crane movement both of them change positions without having to lower the formwork to the ground. Its use is the most widespread for heights of up to 60m-70m.
    3.-Guided climbing formwork; similar to the climbing formwork, where the formwork-platform assembly is changed in height (toned) guided by rails fixed to the concrete, so that the formwork change with higher wind speeds is allowed. Its use is usually limited to work at heights between 50 and 100m.
    4.-Self-climbing formwork. They are climbing systems similar to those of guided climbing, but in them it is not necessary to use a crane to change the position of the formwork-platform assembly, when performing both the guide rail and the formwork assembly itself and platforms using systems integrated hydraulics. Its use is usual in supports of more than 100m high (pylons, elevator cores in high-rise buildings, etc).
    5.-Sliding formwork, which are completely different systems from the previous ones, in which a small formwork slides constantly through the support that is being executed, concreting being carried out continuously. They are systems that are usually used in chimneys, control towers, etc.
    The limitation presented by all the formwork systems indicated above consists of slow execution, since they are not able to perform a daily climbing cycle, and also involve a large amount of work at height.
    DESCRIPTION OF THE INVENTION

    The system of the invention encompasses a set of elements that make it possible to ensure the achievement of a height tonnage for hollow concrete supports in height (shafts, chimneys, climbing walls), etc. within a daily climbing cycle, regardless of geometry and variation of the same that we find, and with the logical limitations that can be found in the case of large formwork surfaces or large volumes of concreting.
    According to the invention, the system comprises:
    -a traditional stackable formwork, which comprises an inner mold and an outer mold supported on support platforms to execute each of the tonings,
    -where the platforms include climbing platforms and additional platforms,
    all the previous elements being tailored to the construction to be executed;
    -and also comprising auxiliary means.
    With the above, paradoxically, high efficiency can be achieved in daily climbing (in an environment between 80% and 90%, higher than other systems) regardless of the height (even up to 100m), concrete volume ( even up to 100m3 / set), or formwork surface (even over 300m2 / set).
    The necessary auxiliary means according to each work can be summarized in the following:
    -Use of ferralla pre-assembly, which is a template in which the ferralla is pre-assembled. -Appropriate lifting means (main crane in height and auxiliary crane on land). -Concrete media (high volume pump or cupola).
    -Means of access and evacuation.
    -Means of control of setting and means of heat input.
    -Supply of electricity and compressed air.
    They are also necessary:
    -Electric and pneumatic hand tool.

    -Topographic control.
    -Explained work of the precise dimensions to each solution.
    -Skilled labor.
    -Quality control security and management by technical staff in charge.
    The way in which all these elements are used and integrated makes the system that a priori would be the most elementary of the traditional systems (stackable formwork) achieve this high efficiency.
    The main reason why the stackable formwork system has been chosen is to minimize work at height. In this way, greater speed is achieved in the execution of each of the activities (by having more space and greater speed and precision in the handling of suspended loads) with greater security by reducing the risks of serious consequences inherent to work in height. It also allows the application of release agents (which act by reducing adhesion) away from the ferralla waits of the previous tongada.
    If it is convenient to manufacture starter pedestals on some or all of the supports, said pedestals will be wide with respect to the lateral surface of the support, and may be solid or hollow. The recess or widening in any case must be towards the outside and inside with respect to said lateral surface of the support a minimum of 10 cm, so that the mold of the starts can be supported in this small heel that generates said recess. The heights of the piles and the sequences of climbs can be tabulated to different values.
    It is also observed that it is preferable to provide a single formwork per set of climbing for the determined pitch height, it being very convenient to split it asymmetrically into two half-forms of different heights so that we adjust as well as possible to the different heights of the different supports , reducing to the maximum the starts and avoiding unnecessary overlaps in the second setting (the one that is done on each start).
    If it is not possible to use starter pedestals with an overshoot, a regularization toning can be carried out in the same way as the support

    (shaft, pillar, etc.) with traditional formwork, so that the elements for supporting the inner climbing platform are placed in the level necessary for the realization of the starting toning, which is the first toning of the support.
    Depending on the heights of the piles and sequences of the climbs, the dimensions of the formwork are tabulated, while a specific formwork set is used for the execution of the solid headboard.
    It may also be necessary to use a climbing formwork set for hollow concrete supports that are capable of concreting the two-sided variable sections of both piles on piles and piles on arcs.
    The formwork molds will normally consist of 4 mm thick sheet in a way that guarantees the durability along the layouts that the material has to receive. In these molds the sheet will be stiffened by vertical profiles IPN (80 for example) welded to horizontal belts (2UPN100 for example) that will compensate the pressure between the facing panels of the molds by means of Dywidag type high strength bars. The distance between vertical profiles will be the criticism determined by its maximum permissible influence width and the maximum allowable span of the 4 mm sheet so that we ensure its flatness and durability throughout its useful life.
    Each formwork mold, for example, can carry 4 or 5 height straps fastened together by means of Dywidag high strength bars. At the upper edge of the mold and above the concrete, there will be some distance strips that will eliminate the elastic arrows of the formwork that would produce deformations in the concrete that could complicate the assembly of the formwork in the next step.
    For the external climbing of each of the formwork sets, the external climbing platforms are arranged, lined with metal frames welded to the corresponding platform, which will be supported on brackets - for example, in four brackets on the wide faces and three brackets on the narrow faces.
    An internal climbing platform, of
    5

    surface adjustable by supplements, lined with tear plate, which will be supported by tilting legs in some holes (recessed) left in the previous tilt in the interior walls of the support, for example by using in the concreting of a recessed boxes placed in the upper area of the mold.
    To allow the passage in the work of formwork, formwork, concreting and puncture of ferralla, the invention comprises, for example, up to three levels of external work platforms (the external climbing platform and two additional platforms) and two interior (the platform of internal climbing and an additional platform) communicated with each other by stairs integrated in the formwork molds themselves, with their corresponding safety protections (backs or rings depending on the cases). The platforms in the stairs area are equipped with hatches that allow access and subsequent closure of the work surface. The railings are completely metal made to measure with a minimum height of 1.00 m with intermediate slat and skirting board of 150 mm.
    Describing in detail the possible configuration of the indicated platforms, it could be:
    -A perimeter outer climbing platform with a free width of 1.00m, tramex floor and equipped with perimeter railing,
    -Two additional external perimeter work platforms, with a free width of 0.75m, tramex floor and equipped with perimeter railing, and arranged at different levels above the external climbing platform.
    -An internal climbing platform, adjusted to 30mm of the concrete contour with tear plate floor; Perimeter protection is achieved with the concrete mold itself or external climbing platform depending on the phase in which we are.
    -An additional interior work platform adjusted to 30mm from the vertical profiles of the inner mold with tramex floor, and arranged above the
    indoor climbing platform. Perimeter protection is achieved with one's own

    inner mold or outer work platform, depending on the phase in which we are.
    All the material used is recoverable except for the obvious passing parts (PVC pipes, PVC cones) of Dywidag bars. In general, the M20x50 high quality screws (Quality 8.8) should be preferably used for joining the formwork panels and the fixing of the external concrete walkways will be done using M20x50 screws (Quality 8.8).
    To achieve high productivity with the system of the invention, the process of the invention must be followed for the execution of each support, which comprises the following steps:
    1-Execution of a pedestal starting or toning of regularization:
    The pedestal can be hollow or solid, being preferred that they are solidified as much as possible. Both in the case of hollow and solid pedestal, the width of the concrete must increase by a minimum of 10 cm both by the inner face and the outside with respect to the lateral surface of the support, so that the formwork used below to execute a dwarf Boot have base where to support.
    In case of regularization toning, it will be done with traditional formwork. Through this toning, the heights of the supports can be regularized so that the rest of the stalls are made by concreting until the formwork is crowned. In the execution of the regularization steps, the placement of the elements where the climbing platforms will be supported must be provided - for example, conical screws for fixing the outer climbing platform and the recesses for supporting the inner climbing platform - a the projected mounting dimensions below the coronation, so that they can be used to execute the start-up. These tonings of regularization are hollow and do not have an overshoot, and will be concreted to an oversize in approximate height of 150mm above the expected height of the tongada, to facilitate the overlap of the starter mold.

    2. - Execute a boot:
    Once the pedestal or toning of regularization has been carried out, then a starter dwarf is executed (starting toner of lower height than the rest of the tonings).
    To execute this starter or starter dwarf, it is preferable to mount the complete formwork outside the support floor, placing it by means of a crane inside the previously made hollow pedestal, or directly supporting the floor on wooden wedges or dowels in the event that instead of a pedestal, it starts from a ton of regularization. Conical climbing screws (9) are embedded in this starter dwarf to secure the external climbing platform in the rear position
    3. -Execute the successive climbing
    Performed a toning, either the previous one or the dwarf (the starting toning) of the support to climb, the formwork will mount on the conical climbing screws left in the concrete in the previous setting (starter dwarf or previous toning), some consoles or brackets of the outer climbing platform, and will mount on said same outer climbing platform. Said outer consoles of the climbing walkways are fixed to the tapered climbing rollers normally with M-30x70 (8.8) DIN933 screws. The console elements that have just been released from the previous setting are recovered. To do this, work must be carried out from the crane's suspended basket, which must be conveniently approved.
    The inner climbing platform will be placed on the new work level, with its legs resting on the holes left in the concrete by the molds or recessed boxes, by hoisting with a crane if it was already placed at the work level of the previous stage, or by introduction into the hole when it is first placed, after the starter dwarf.
    Then it is placed resting on the inner platform of climbing the mold
    inside the formwork, which has been previously preassembled, and then
    9
    5
    10
    fifteen
    twenty
    25

    proceeds to place the additional work platform inside on the horizontal straps of the upper level of the inner mold. In all these tasks, the formwork enters the interior of the inner mold through the door prepared in it for such purpose so that they can complete the exact placement work of said mold and the additional interior work platform, as well as release the Crane chains if applicable.
    Then proceed to thread the pre-assembled ferralla, as well as adjust fences in the area of overlapping the bars, so it is essential not to have the recessed boxes still in place. To do this, while some formwork guides the rail with ropes from the outside of the mold, others are kept under shelter under the additional work platform inside. Once embecada the ferralla will ascend to said additional platform of inner work to accompany the ferralla in the lining, avoiding hooks with the mold, and finally to destroot the load.
    From this additional interior work platform, the recessed boxes are placed; In addition, Dywidag bars will be placed from the inside of the inner mold on the straps with their corresponding plate and nut with wings, so that they are prepared to thread the corresponding PVC pipes from the outside.
    Next, the outer mold consisting of several pieces is closed, which will be mounted one by one, threading the Dywidag bars and adjusting the nuts on the outside of the mold. To do this, while some formwork guides the panels from the additional interior work platform in a way that facilitates the assembly of the same, other operators located on the outer platforms carry the mold at a height, assist in the routing of Dywidag bars and level the panels. This outer mold integrates the additional outer work platforms.
    The conical screws for the next climb will be placed from the additional outer work platform located at a higher level.
    Next, superior spacer strips will be mounted between both sides of the formwork, necessary to avoid elastic arrows on the upper edge
    5
    10
    fifteen
    twenty
    25

    35
    of the mold that avoid complications in the closing of the formwork in the following setting. The mold is ready to be concreted, however it is advisable to grease the conical climbing screws and the recessed truncated pyramid molds to facilitate their demoulding.
    The concreting is then carried out, always respecting the minimum filling times depending on the consistency of the concrete and its setting time in the pouring conditions, so that the maximum design pressures are not exceeded.
    After sufficient setting, the form is removed, removing all recoverable material.
    Next, the inner mold will be disassembled starting with the additional inner work platform, followed by the tile panels (panels with divergent sides in the direction of extraction to facilitate the removal of interior molds where the pressure is pressed so that it would not be possible to remove the formwork without said divergence) to finally remove the rest of the panels of said inner mold.
    Then the outer mold (which includes the additional outer platforms) is removed by lowering the panels to the floor for cleaning and application of release agent for the next laying.
    The climbing phase ends with the lifting of the climbing platforms until the next work level; the exterior is hooked (each of its parts or sectors) one by one with the crane moving to its new position, in which the consoles or brackets have already been placed on the conical climbing screws left in the previous setting. At this time both the outer and inner climbing platform are already in their new position starting a new climbing cycle.
    For the lifting of the internal climbing platform, before the formwork exits the interior of the formwork, they will remove a supplement or sector of the internal climbing platform and hook the crane chains to it. When lifting the support platform, the legs will be collected until they find the next hole left in the upper area of the tilt by the recessed molds. In this
    eleven

    10
    fifteen

    point the support legs will reopen allowing the crane to leave the inner support platform in its new position.
    The formwork in its exit of the inner hollow will go down the outer mold, unscrewing said outer mold in its parts to proceed to remove them by crane.
    For the access of the workers to the external climbing gateways it is advisable to mount an access ladder next to the front faces of the construction support, which must be located in front of the wide faces of said support at a distance greater than the platform's width of external climbing and anchored to it, taking advantage of the hooks provided by the conical climbing screws of previous tonings.
    If you need to pre-assemble the rail before mounting it may be necessary to use a lifting tool, with a load of 15,000 or 18,000 kg for example
