Definitions

  • the invention relates to a system formwork for a concrete ceiling having a joist with side formwork elements for the side surfaces of the joist, the formwork skin of which is attached to beams running transversely to the longitudinal axis of the joist, with bottom formwork elements for the bottom surface of the joist, which have at least one formwork skin, and with Devices that connect the side formwork elements together.
  • This beam formwork which is always rigid at the place of use, must fit very precisely into the ceiling formwork; it is hardly possible to clamp it together with the ceiling formwork to seal joints.
  • the production of this joist formwork and its insertion into the slab formwork requires a considerable amount of work.
  • This girder formwork is also very heavy and can no longer be switched on and off by hand.
  • the invention has for its object to develop a joist formwork that is not only easily installed in the slab formwork, but can also be easily expanded after concreting, which is handy and still accurate and true to size.
  • a particular advantage of the invention is that the pivoting suspension of the side formwork elements on the slab formwork allows the beam formwork to be assembled at the place of use and therefore the individual parts of the formwork can be brought to the place of use in handy sizes.
  • the shells of the joist is very simple, because d 'l rch effortless swiveling of the side formwork elements the correct dimensions can be easily produced, at least in the lower area of the beam formwork.
  • the formwork so difficult in the known beam formwork can also be accomplished very easily in the formwork according to the invention, because after loosening the fastening means holding the formwork together at its lower end, the side formwork elements only have to be pivoted apart again in order to be able to remove them.
  • a side formwork element can be chosen smaller than the distance between two adjacent supports supporting the ceiling formwork in the ceiling formwork according to the invention due to the lack of the longitudinal beam necessary in the known beam formwork, if such a large swivel angle is required to remove the side formwork elements, the freely hanging legs of the ceiling formwork elements can be pivoted into the space between two ceiling supports. If a side shell element is located in the area of a ceiling prop, it can be pushed in its place after removal of the adjacent side shell element and then also through Swing into the space between two floor props can be removed. This is not possible with the known beam formwork according to the Heilwagen, because there the supports engage directly on the side member, a distance between the supports larger than the length of the side member is not possible, because then the support of a side formwork element would no longer be supported.
  • the side formwork elements are held in the yoke after lowering and in the laterally moved position in the known joist formwork, the side formwork elements cannot be easily detached from the clamp in the known formwork.
  • the formwork according to the invention it is possible first to remove the bottom of the girder formwork and only then to remove the hanging side formwork elements individually, so that individual elements of the girder formwork which can be easily transported by hand can be removed without the need for to support certain parts additionally when striking and without the risk that unsecured parts accidentally fall down when stripping.
  • the side formwork element has its pivotable suspension on the Dek kenschalung a leg forming a portion of the slab formwork, which has projections and / or bearing shells, which cooperates with bearing shells and / or projections of a part of the slab formwork, so that these interlocking parts define and fix the pivot axis.
  • This embodiment of the invention can be further developed in such a way that the mutually cooperating joint parts consist of interlocking hook-like parts; in particular, the means arranged on the ceiling formwork for pivoting suspension of the side formwork element can have hook-like parts in cross section.
  • the pivot axis can either run in the immediate vicinity of the end of the horizontal leg facing away from the beam or at a distance from this end. In embodiments of the invention, the pivot axis can run in or in the immediate vicinity of the formwork skin of the horizontal leg or at a distance from the formwork skin of the ceiling formwork, for example on the lower surface of the horizontal leg and, for example, also below the end of the horizontal leg facing away from the beam.
  • the pivot axis extends in the formwork plane or in the immediate vicinity of the formwork plane and at the end of the horizontal leg, then when the formwork is removed after loosening the fastening means holding the lower ends of the vertical legs of the side formwork element, they can be pivoted slightly outwards. No stripping play is theoretically required for this if the swivel axis runs exactly in the formwork plane. In practice, however, this is difficult and in practice, the interlocking parts forming the swivel axis usually have some play.
  • the stripping play required must be greater, the greater the distance between the pivot axis and the formwork skin of the horizontal leg. Measures for obtaining such a stripping game are not necessary, however, if, according to one embodiment of the invention, where the horizontal leg and the vertical leg of the side formwork element meet, the side formwork element is not delimited by an edge which is rectangular in cross section, but by a circular arc section whose radius intersects the swivel axis.
  • a haunch is provided at this point, the edges of which lie with the horizontal formwork surface and the vertical formwork surface approximately on an arc around the pivot axis.
  • the inclined surface of the haunch can also extend over the Extend the line that contains the base of a plumb bob fallen from the swivel axis onto the vertical formwork surface and extend over the entire height of the vertical formwork.
  • the inclination of the haunch surface with respect to the vertical surface is extremely small if the pivot axis runs at the lower edge of the end surface at the end of the horizontal leg.
  • the greatest thickness of the horizontal leg of the side formwork element forming the slab formwork section is so much smaller than the drop height of the Fallko p fes that when striking these horizontal legs it can be pushed over the edge of the formwork surface of the slab formwork.
  • the length of this leg can then be chosen so that the side formwork element can be pivoted so far about the upper edge of the end face of the ceiling formwork element facing the beam that the horizontal section of the side formwork element between the edge of the ceiling formwork and the beam can be removed from the ceiling formwork .
  • the entire slab formwork When striking, the entire slab formwork can be lowered in a manner known per se, first by lowering the falling heads of the slab formwork, then the side formwork elements, because they hang in the slab formwork, that is, as a rule, are suspended in a hook open at the top be lifted. Then the horizontal leg is pushed over the adjacent ceiling formwork element and then the lower end of the side formwork element is pivoted far outwards.
  • the stripping of the beam formwork according to the invention is particularly simple and effortless.
  • the angular shape of the side formwork element and its suspension at the outer end of the horizontal leg has the advantage that the vertical leg of the side formwork element hangs obliquely outwards after hanging in the ceiling formwork, i.e. the lower end of the side formwork elements arranged opposite one another has a greater distance than theirs top end.
  • these ends endeavor to lie against the legs of the clamp engaging below and when the clamp is tensioned, that is to say when the side formwork elements pivot inwards, in contact with the lower ones Stay overlapping ferrule legs.
  • the side formwork element can be suspended from a beam of the ceiling formwork, but it can also be partially suspended directly from the drop head of a ceiling support.
  • the pivoting movement of the side formwork elements directed towards the beam is limited by a stop in the position in which the side formwork element adjoins the ceiling formwork zenden ceiling formwork element forms the intended angle.
  • a stop results in the desired angle, usually this angle will be a right angle, when the vertical legs of the side formwork elements are clamped together.
  • the stop limiting this pivoting movement can be attached to a part that does not belong to the side formwork element or ceiling formwork element.
  • the aforementioned embodiment can, however, be further developed in such a way that this stop between the side formwork element and the ceiling formwork element is effective, so that when the desired angular position is reached, the previously articulated connection behaves like a rigid angular connection by removing the pivoting possibility.
  • the side formwork element carries out a translational movement in the direction of the beam, in which the ceiling formwork element, which is now rigidly connected via the pivot axis, is supported, supported by formwork supports.
  • the slab formwork element can take part in this translational movement because the slab formwork is "softly" supported in this direction, the supports for the slab formwork are slightly inclined bPi this small correction movement, without this having any recognizable disadvantages.
  • a stop limiting the pivoting movement is formed by the contact of the side face of the ceiling beam on a bar connecting the webs of the side formwork element and forming the end face of its horizontal leg.
  • the pivotable suspension of the side formwork element on the slab formwork is designed so that this hinge connection absorbs the tensile forces that occur in the aforementioned case when the pivoting movement is blocked and transmits them to the slab formwork.
  • the side formwork element is suspended from a support of the ceiling formwork (ceiling support) and the pivot axis of the pivoting movement is at a distance from the horizontal formwork surface
  • the end faces of surfaces of the ceiling formwork and end faces of the articulation axis located above horizontal section of the side shutter element are given a course in which they come to rest against each other to limit the inward pivoting movement of the side shutter element and thus form the stop limiting this pivoting movement in this pivoting direction.
  • embodiments of the invention can be designed such that the ceiling support on its side surface in Distance from the formwork surface has open hooks in which the side formwork element engages.
  • the leg of the side formwork element forming the slab formwork section can have on its underside a downwardly projecting strip which engages in the hook base.
  • This embodiment of the invention can be further developed in such a way that the bar is connected to the carrier of the side formwork element by webs running transversely to the longitudinal axis of the beam, these struts preferably being formed by angling at the upper end of the carrier, and that the webs have one at their lower edge Have recess for receiving the hooks arranged on the slab formwork beam.
  • This recess can be followed by a further, less deep recess, which then forms part of the articulated connection of the side formwork element to the ceiling formwork if the ceiling formwork element adjacent to the side formwork element has no hooks, but rather the horizontal leg of the side formwork element has to be placed on a strip .
  • the webs angled from the carrier of the side formwork element carry the formwork skin of its slab formwork section and the ends of the webs of adjacent beams are connected to one another by a strip, preferably the webs are connected to one another in pairs by the strip.
  • This embodiment of the invention can be further developed in such a way that the distance between the hooks on the longitudinal ceiling beam is smaller than the length of the bar that is supported in the hook base.
  • the side formwork elements can be moved along the formwork plane as required and do not have to be hung in a position determined by the hooks.
  • the bottom formwork elements are longer than the side formwork elements. Since the lower ends of the side formwork elements are tensioned against the end faces of the bottom formwork elements, this ensures that the bottom formwork elements align the side formwork elements in the longitudinal direction and that this alignment is transmitted to the slab formwork via the rigid joints when the clamp is tensioned.
  • the horizontal and / or vertical formwork skin sections can be fastened to the side formwork element after it has been suspended. Since the joist formwork according to the invention is usually assembled at the place of use by first hanging the side formwork elements and then attaching the formwork element and pressing the lower ends of the side formwork elements, it is advantageous if the individual parts to be transported to the place of use are as light as possible , which can only be achieved by attaching the formlining after the side formwork elements have been attached.
  • the girder formwork at the lower end of the side formwork elements can be closed in various ways in the formwork according to the invention. In one embodiment of the invention, this is done with a device which uses the known principle of the beam clamps at night and in which the yoke of the clamp can be fastened to the Sellenschaliata in a manner which is known per se is.
  • This embodiment can be further developed in such a way that, according to the invention, the yoke of the clamp can be brought up from below into its fastening position on the hanging side formwork elements, and that the effective length of the yoke of the clamp can be adjusted.
  • the clamp can also be easily attached from below to the side formwork elements hanging from the slab formwork.
  • the lower ends of the side formwork elements can be swiveled inwards at the same time as the yoke of the clamp is adjusted.
  • the adjustability of the ferrule yoke to its effective length can be achieved in various ways.
  • two displaceable sections are arranged on a yoke rod. This has the advantage that the two sections can be designed identically.
  • the sections can be guided with a relatively large amount of lateral play on the yoke, so that the displacement movement is insensitive to lateral tilting.
  • the sections can be secured in their mutual position by means of aligned holes arranged in both sections and pins inserted into them, or also by a tension rod inserted into the hollow profile of the yoke and extending in the yoke axis with tensioning means arranged at its ends.
  • the sections can be determined in their mutual position by wedges which are driven in after the correct yoke length has been set.
  • the bottom form element is arranged between the lower ends of the side form elements, so that these ends are clamped against the end faces of the bottom form element when the clamp is tensioned. This not only has the advantage that the joint between the lower formwork element and the side formwork element is tight and even with one Preload can be tensioned, which corresponds to the pressure of the concrete during pouring and shaking, but also that the distance between the lower ends of the side formwork elements does not have to be specified in particular, but results automatically by contact with the bottom formwork element.
  • the height-selectable fastening of the beam clamp can be done in various ways, it is essential that it is brought up to the beam formwork from below and can be tensioned in this position.
  • the yoke of the clamp can be attached directly to supports of the side formwork elements, in which case the supports of these side formwork elements are extended beyond the lower end of the formwork skin, so that these supports form the clamp legs directly, or else clamp legs can be rigidly attached to the displaceable sections of the yoke be, which in turn can be fastened selectively in height to the back of the side formwork elements, these legs rigidly connected to the yoke not only taking on the function of fastening the clamps at a certain altitude, but also the function of determining the side formwork element in one Angular position to be fixed conditions, so that these clamp legs when tensioning the clamp also have the effect that the inward pivoting movement of the side formwork elements is limited about the pivot axis and the ceiling formwork is pulled along with further tensioning of the clamp.
  • embodiments of the invention can be designed such that the carrier of the side shell. have teeth protruding outwards at right angles to the longitudinal beam axis, which are used to select the fastening height of the lower formwork element.
  • the distance between the teeth can expediently be between 2 and 3 cm. This has the advantage that the position of a clamp hooked into a wrong tooth deviates relatively strongly from the position of the other clamps, so that this is immediately apparent.
  • strips extending transversely to the yoke are attached to the mutually displaceable sections of the yoke, which are suitable for engaging in the tooth bases between the teeth of the wearer.
  • fastening for fastening the clamp which can be selected in height, can also be selected, for example perforated rails, in the holes of which either the clamp legs or the clamp yoke are fastened directly with the aid of bolts.
  • the strip which engages in the tooth bases can be arranged above or below the ferrule yoke, but only below if the carriers are extended beyond the lower edge of the formlining of the side formwork element and there support teeth.
  • the two sections of the yoke have stops arranged at a distance above the formlining of the lower formwork element at a rigid angle to the longitudinal axis of the yoke, which are used for bearing against the side of the side achal element facing away from the formwork skin. These stops are arranged so that the side formwork element is at the desired angle - normally a right angle - when the clamp is tensioned.
  • the distance between the two formwork elements is determined by the width of the formwork skin of the bottom formwork element.
  • the upper stop located on the clamp legs pulls the side formwork element with it and possibly also the ceiling formwork with the supports, since the supports are not rigidly anchored at their upper end attached to the ceiling formwork.
  • the contact of the lower end of the side formwork element on the end face of the formwork skin of the lower formwork element is limited, the inward pivoting movement of the side formwork element both at the connection of the side formwork element to the ceiling formwork and by this stop of the side formwork element on the bottom formwork element.
  • these stops can also be formed by a transversely extending strip and the distance of the stops from the lower end of the formlining of the side formwork element can be approximately one third of the height of the side formwork element.
  • stops acting on the rear of the side formwork elements at different heights can be provided on clamp sections.
  • the stops can be arranged in such a way that one stop acts above the level of the formlining of the lower formwork element and the other stop below this level on the rear side of the side formwork element.
  • the beam formwork can be clamped together using individual clamps.
  • two mutually adjacent clamps are always rigidly connected to one another in pairs, for example by the bar engaging in the tooth bases and / or by the bar which is at a distance above the yoke and transversely to the longitudinal direction of the yoke at the rear of the side formwork element stop coming to rest.
  • the strips are always longer than the distance between two beams of the side formwork element, it is not necessary that the side formwork elements of the formworks lying opposite one another lie exactly opposite one another, rather the position of the side formwork element is along the side surface of the beam completely regardless of where the opposite side formwork element is located. This is particularly advantageous if, due to any protrusions projecting laterally from the beam, the continuously continuous side surfaces of the beam are not of the same length on both sides.
  • the formwork element consists of squared timbers arranged on the ferrule yokes and a formwork skin loosely placed over them.
  • the squared timbers can also be placed loosely on the Zwingenjoch or can be fastened on the Zwingenjoch.
  • the under-beam formwork according to the invention is particularly easy to use.
  • this has the advantage that the squared timbers do not interfere if the girder is so narrow that it is binding with the side surfaces of a concrete support, that is to say the side formwork elements are moved so close together that they abut the side surfaces of a concrete support.
  • the bottom formwork elements can have only one formlining alone, or can also have additional supports that support the formwork facing. It is not necessary for the bottom formwork elements to be supported on the yoke of the clamp. Rather, in one embodiment of the invention support strips nailed to the inner surface of the formlining of the side formwork elements, onto which the formwork skin of the bottom formwork element or the entire bottom formwork element is then placed when the side formwork elements are pivoted in.
  • the particular advantage of this embodiment of the invention is that the width of the girder can be adjusted by cutting the lower formlining, which extends over several lengths of the side formwork elements, and by automatically aligning the side formwork elements to this dimension, the other dimensions are exactly maintained.
  • the vertical dimensions of the girder formwork can also be easily adjusted by releasably attaching the clamp to the teeth of the side formwork elements at a selectable height, with a dimension between the dimensions of the tooth being set by selecting the height of the squared timbers resting on the yokes or corresponding intermediate layers can be.
  • this projection can be formed by a plate arranged at the lower end of the extension of the carrier, which plate also forms a base plate for the side formwork element.
  • the lower formwork shuttering at the lower end of the side formwork elements does not take place by means of a beam clamp surrounding the side formwork elements, but the side formwork elements are detachably connected to one another by floor brackets which run from the inner surface of one side formwork element to the inner surface of the other side formwork element and at least the fastening means between one end of the floor support and the adjacent side formwork element can be released when stripping.
  • the girder formwork can be dismantled into easily transportable individual parts when stripping. First of all, the connection between one end of the floor beams and the adjacent side formwork element is released and then the side formwork elements are pivoted outwards, if necessary after lowering the ceiling formwork.

  • the holes in the formlining that are not required are closed with plugs.
  • the advantage of this embodiment is that not only the same side formwork elements can always be used when formwork of different high beams, but also the adjustment of the formlining to the respective height of the beam is no longer necessary because the lower formwork element, i.e. the formwork floor in any Height between the two side formwork elements can be fixed without the formwork skin projecting further downward hindering the fastening of the formwork floor.

A row of holes is provided in this plate, the holes of which are at a distance from one another which is smaller than the distance of the holes in the formwork skin. This allows the height of the formwork floor to be selected in very small steps.
  • the floor supports can also be designed in a wide variety of ways.

This allows the length of the shelf supports to be adjusted easily and also in very small steps.
  • This embodiment can be further developed such that the sheets are reinforced by folding their edges.
  • Such floor supports are extremely stable. Since the holes in the formwork skin are provided in the area of the vertical support legs of the side formwork elements and also put them through, when attaching a floor support, for example by only two wedge bolts or screws, a rigid structure is created, which also allows one to be attached to only one formwork element when formworking to support the bottom formwork containing the bottom girder at its projecting end with a support and then to attach the reinforcement of the girder to the bottom formwork element.
