Definitions

  • the invention relates to a slab formwork system with a plurality of grate elements, each consisting of a plurality of mutually parallel longitudinal members and at least one mounted on vertical supports or be laid, transverse to the longitudinal members extending cross member.
  • Such a slab formwork system is known from German Offenlegungsschrift DE 102 34 445 A1 the applicant known.
  • a plurality of mutually parallel side members are connected to each other via grills provided on its underside to each other to grate elements, that the relative positions of the side members are fixed to each other.
  • the said spars are provided at a relatively large distance from the front ends of the side members spaced apart.
  • each with the same grate elements can be placed with perpendicular to the cross beams longitudinal members on the cross member from above. Due to the fact that the longitudinal members are not fixedly connected to the cross members and the spars are provided spaced from the front ends of the longitudinal members, it is possible to interlock in the longitudinal direction adjacent grating elements with each other, so that in each case a portion of a longitudinal member of a grate element between two Side members of a comes to rest with this toothed grate element. In this way, a longitudinal compensation can be made by said intermeshing of the grate elements, which means that can be set with the said slab formwork system in the longitudinal direction of the side members individual dimensions that can be selected independently of the grid size of the grate elements.
  • the length-adjustable plank consists essentially of two grate parts, which are each composed of two mutually parallel longitudinal members and perpendicular to these longitudinal members extending transverse webs.
  • the longitudinal members of the second grate part have a slightly smaller distance than the longitudinal members of the first grate part, so that the second grate part can be moved together with its transverse webs in the longitudinal direction relative to the first grate part, provided that the second grate part by means of threaded spindles relative to the first Rust part was previously lowered.
  • the second grate part can be raised again by means of the threaded spindles, whereby cross members of the second grate part come to lie alternately with cross members of the first grate part at the same height level. In this way can be realized with the length adjustable plank thus a longitudinal compensation.
  • An object of the invention is to provide a slab formwork system of the type mentioned in such a way that a slab formwork can be adapted not only in the direction of the side members, but also perpendicular thereto to individual size ratios, in particular Also a quick, easy and safe mounting and dismounting of the slab formwork system should be ensured.
  • This object is achieved by the features of claim 1 and in particular in that the longitudinal and transverse members of the grate elements are rigidly interconnected, wherein standard grate elements have two provided in the opposite end portions of the longitudinal beams cross member, while transverse compensation grate elements one or two in comparison to the standard grate elements in the longitudinal direction offset inwardly arranged have cross member.
  • the longitudinal members of a grate element are not connected in a known manner via separate spars, but the connection of the longitudinal members of a grate element is realized directly via one or more fixedly connected to the longitudinal beams cross member, which in turn are then adapted to be placed or mounted on vertical supports to become.
  • the invention thus already achieved that the number of parts to be handled compared to known slab formwork systems is reduced because cross members and side members each form firmly connected units or grate elements, so that cross member and side members no longer need to be handled separately.
  • the grate elements are provided in at least two mutually different embodiments, with the standard grate elements defined above being realized in concrete terms, as well as the already mentioned cross-compensating grate elements.
  • the standard grate elements defined above being realized in concrete terms, as well as the already mentioned cross-compensating grate elements.
  • This Quunters Diess- and grate elements differ from the standard grate elements in that its or their cross member are further offset inwardly.
  • This surprisingly simple measure makes it possible to interlock a standard grate element and a transverse compensating grate element in such a way that an outer longitudinal member or else a plurality of outer side members of a transverse compensation grate element respectively lie between two adjacent longitudinal members of the standard grate element.
  • all the longitudinal members of the standard and the cross-compensation grate element extend parallel to each other, wherein they are all spaced from each other transversely to their longitudinal direction or arranged with their longitudinal sides adjacent to each other.
  • the longitudinal members of the standard grate elements have the same length as those of the transverse compensation grate elements.
  • Such a system which e.g. two different classes of standard grate elements and appropriately trained cross-compensating grate elements is used, will be explained in more detail in the description of the figures.
  • the transverse compensation grate element according to the invention is "threaded" from below into the standard grate element, which means that first the one end ends of a respective desired number of longitudinal members of the transverse compensation grate element from below between the respective longitudinal members of the standard grate element introduced and moved over the one cross member of the standard rust element away from inside to outside. This movement is then continued in the direction of the longitudinal members until the other ends of the longitudinal members of the cross-compensation grate element can be raised above the other cross member of the standard grate element and supported on this.
  • the said process of threading is described in more detail in the description of the figures.
  • the distance between adjacent longitudinal members of the grate elements is at most 20 cm. With such distances can be avoided with the greatest possible certainty that a fitter can fall between two adjacent side members through, so that a mounted inventive grate element represents a reliable fall protection.
  • the distance between adjacent side members must be at least as great as the width of the side members, so that a side member of a cross-compensating grate element between two adjacent side members of a standard grate element can be moved. It is particularly preferred if the distance between adjacent longitudinal members of the grate elements is at least two or three times the width of the longitudinal members.
  • the already mentioned longitudinal compensation grate elements are provided in addition to the standard grate elements and the transverse compensation grate elements which have one or more cross members only in one of the two end regions of the side members facing away from one another ,
  • longitudinal compensation grate elements and ceiling formwork systems can then be constructed, which have individual, continuously adjustable, bound to any pitch dimensions in the direction of the side members.
  • the longitudinal compensation grate elements with their cross member or the cross member opposite side between two adjacent side members of a standard or a cross compensation grate element over the respective required distance insert are possible.
  • the insertion must take place at least so far that the cross-beam-free ends of the longitudinal compensation grate element come to lie on cross members of a standard or a transverse compensation grate element. At most, the longitudinal compensation grate elements can be inserted so far until their cross members or their cross members abut the cross members of a standard grate element or a transverse compensation grate element. Infinitely any insertion positions can be selected between these two extreme positions in order to be able to produce individual dimensions in the direction of the longitudinal members.
  • the longitudinal compensation grate elements can be inserted when the standard grate elements adjoining them and / or cross compensation grate elements already mounted. It is possible that when mounted slab formwork or the cross member of a longitudinal compensation grate element are arranged on the outside with respect to the overall formwork, wherein the longitudinal members of the longitudinal compensation grate element facing inward. Alternatively, however, it is also possible to slide a longitudinal compensation grate element from the bottom of another grate element forth with its cross beam free end from the inside via a cross member of the other grate element, so that the longitudinal members of the longitudinal compensation grate element ultimately in the mounted position on the cross member of the other grate element outwardly project.
  • combi compensation grate elements are also provided which have one or more crossmembers offset inwardly in one of the two end regions of the side members facing away from one another. With such combination compensation grate elements can thus simultaneously a transverse compensation and a longitudinal compensation can be created. This will be illustrated in the description of the figures.
  • a constellation can exist in certain installation situations in which a longitudinal support of a transverse compensation grate element, a longitudinal support of a longitudinal compensation grate element and also a longitudinal support of a combi balance element.
  • Rust element come to rest between two adjacent longitudinal members of a standard grate element. In this case, then the distance between adjacent side members a standard grate element amount to at least three times the width of the side members. In principle, it is preferred if adjacent side members of all the grate elements are respectively spaced apart in the same way and / or if the side members of all grate elements have mutually equal lengths.
  • Stirnabschalungs between the end regions of two adjacent side members can be attached to these.
  • Stirnabschaloder can be mounted on these Stirnabschalungsriadn, which extend perpendicular to the actual formwork skin and thus limit a receiving area for the applied to the formwork concrete and frame.
  • Such Stirnabschalungsriad can be particularly easy to assemble when the particular peripheral edge region of a mounted slab formwork is formed almost exclusively by longitudinal members, which extend perpendicular to the respective edge region. In this case, then Stirnabschalungs lacking can be mounted at any position between adjacent side rails.
  • a side rail of at least one cross-compensation grate element is longer than the distance between two cross members of a standard grate element, wherein at the same time the remaining side members of the respective cross-compensation grate element are dimensioned shorter than the distance between two cross members of a standard grate element ,
  • the transverse compensation grate element in a substantially vertically aligned position with to position the longer side member above a cross member of a standard grate element, then up in a further substantially vertical position and then to position with the other end of the longer side member above another cross member of the standard grate element, so that the cross compensation grate element vertically hanging coupled with the standard grate element. Subsequently, the transverse compensation grate element can then be pivoted into a substantially horizontal position.
  • the longer side member of a transverse compensation grate element can protrude with its two end regions over the ends of the shorter longitudinal member of the respective transverse compensation grate element adjacent to it.
  • the remaining, shorter side members of the cross-compensation grate element do not collide with cross members of a standard grate element when the cross-compensating grate element is pivoted into its horizontal position.
  • the longitudinal extension of the longer longitudinal member of a transverse compensation grate element can substantially correspond to the distance of the mutually remote outer sides of two cross members of a standard grate element. In this way, it is achieved that the longer side member of the cross-compensating grate element in its mounted position does not project beyond the side members of that standard grate element into which it has been threaded.
  • the longer side member preferably has a smaller cross-section and in particular a smaller height than the remaining side members of a cross-compensating grate element, this cross-section in particular being rectangular. It is particularly advantageous if the diagonal dimension of the longer longitudinal member is less than the height of the remaining side members. This ensures that the cross-compensating grate element can also be switched on and off when a formwork skin rests on the standard grate element, with which the cross-compensating grate element is or is coupled. Because of its dimensions, the longer side member does not abut on the underside of this formwork skin when the transverse compensation grate element is pivoted.
  • the crossbeams of all grate elements present in the respective formwork are arranged below the longitudinal members. This ensures that the upper sides of the longitudinal members can each form smooth bearing surfaces for a formwork, which is not interrupted by any provided for top cross member grooves, recesses or the like. A direct contact between formwork and cross members so according to the invention does not take place, since only the tops of the side members form the support surface for the formwork.

  • Fig. 3 shows a longitudinal compensation grate element 12, which in turn consists of six parallel and spaced apart extending longitudinal beams 14 and two perpendicular thereto extending cross members 16.
  • the cross members 16 are both arranged in the same end-side end region of the longitudinal members 14, which leads to the fact that the opposite end-side end region of the side members 14 is designed without crossbeams.
