Definitions

  • the invention relates to a formwork frame for a formwork element of a ceiling formwork.
  • the invention further relates to a formwork element with such a formwork frame or a ceiling formwork with the formwork element.
  • the invention relates to a method for building such a ceiling formwork.
  • a compensating element for closing a gap in a ceiling formwork which has several standard formwork elements with a frame closed on the periphery. If the erection of the ceiling formwork is hindered by an obstacle in the form of a column, the compensation element with a U-shaped frame can be hooked into the formwork supports from the ground so that the column is received inside the U-frame. The U-frame is then swiveled open from below and provided with two additional supports. Then a second U-shaped frame is assembled from below to obtain a closed frame. The compensation element therefore enables the column to be converted. In this prior art, the U-frame is hung in the formwork props from the ground. Due to the U-shape of the frame, however, it is necessary to attach the formwork facing and additional formwork supports to the frame after they have been pivoted open.
  • the WO 2019/025513 A1 shows a ceiling formwork with a lost formwork panel.
  • this prior art is not suitable for converting an obstacle.
  • the object of the present invention is to alleviate or eliminate at least individual disadvantages of the prior art.
  • the invention aims in particular to create a formwork frame which enables versatile applications, in particular the simple and safe conversion of obstacles within a ceiling formwork.
  • An "I-shaped" shuttering frame is understood to be a shuttering frame that has a permanent I-shape or a defined concreting position with an I-shape.
  • an obstacle such as a column can be received on both longitudinal sides of the formwork frame, namely within the first or within the second recess.
  • the first and second recesses preferably have essentially the same extent parallel to the plane of the formwork facing.
  • the formwork frame has a first and a second cross member, which are shorter compared to the connecting web.
  • the first cross member is suspended in the two first formwork supports in such a way that the formwork frame is arranged in an intermediate position that is inclined downwardly from the first cross member along the connecting web.
  • the second cross member is in the intermediate position near the floor, so that in the intermediate position at least one further element, such as a panel element and / or a longitudinal member, in particular also with it releasably held formwork panel on which the formwork frame can be arranged.
  • a formwork element is obtained which can be pivoted up as a whole from the intermediate position into the preferably essentially horizontal use or concreting position.
  • the first and second cross members therefore make it possible to attach the formwork elements even in the intermediate position, which considerably increases safety when converting the obstacle.
  • the first and second cross members and the connecting web are preferably made of metal.
  • the first cross member has a first receptacle and / or the second cross member has a second receptacle for detachable connection to a further element, in particular a longitudinal member and / or a panel element, of the formwork element in one direction from the first cross member along the connecting web of the second cross member downwardly inclined intermediate position of the formwork frame.
  • the formwork element can be detachably connected from the ground to at least one further element, in particular a longitudinal beam or a panel element.
  • a first form-fitting connection, in particular a first hook, bolt or latch connection, between the further element and the first receptacle of the first cross member and / or a second form-fitting connection, in particular a second hook, bolt or latch connection, between the further element is preferred Element and the second receptacle of the second cross member provided. It is particularly preferred if the further Element, so in particular the panel element or the longitudinal beam, are releasably connected to both the first receptacle and the second receptacle.
  • the second cross member is in the inclined intermediate position near the floor, so that the further element can easily be hooked into the formwork frame from the floor.
  • the first and / or second receptacle is designed to hold the further element in the inclined intermediate position independently, ie without tools and without manual support, on the formwork frame.
  • the further element can already be fixed in the intermediate position on the formwork frame before the formwork frame together with the longitudinal beam or panel element arranged thereon is swiveled up into the position of use and placed under it with two second formwork props.
  • the construction of the ceiling formwork can be designed particularly easily and safely.
  • the first receptacle has a first receptacle groove and / or the second receptacle has a second receptacle groove.
  • the further element has corresponding hook elements at opposite ends, which can be connected to the first or second receiving groove of the formwork frame.
  • the first receiving groove preferably extends essentially in the direction of the longitudinal axis of the first cross member (ie in the transverse direction of the formwork frame).
  • the second receiving groove preferably extends essentially in the direction of the longitudinal axis of the second cross member (ie also in the transverse direction of the formwork frame).
  • the first or second receiving groove preferably extends over more than a quarter, preferably over more than half, in particular over more than three quarters, of the length of the first or second cross member. This achieves a high degree of flexibility in the arrangement of further elements such as longitudinal beams and / or panel elements.
  • the same I-shaped formwork frame can therefore be equipped with longitudinal beams or panel elements, depending on the application.
  • the first receiving groove has a first undercut and / or the second receiving groove has a second undercut for engagement with a hook element of the longitudinal beam and / or a hook element of the panel element for secure arrangement of the longitudinal beam or panel element in the inclined intermediate position.
  • the engagement of the hook element on the side member or panel element in the first or second receiving groove causes a positive fit which prevents unintentional loosening of the side member or panel element regardless of the forces acting in the intermediate position, without the workers having to touch the side member or the panel element in the intermediate position and when swiveling the formwork frame up.
  • the first receptacle has first receptacle points at defined intervals in the longitudinal direction of the first cross member and / or the second receptacle has second reception points at defined intervals in the longitudinal direction of the second cross member.

  • the second brackets on the second cross member are brought into engagement with the second formwork props, so that the Formwork element is arranged in the intended concreting position.
  • first and second formwork props have engagement elements, in particular hooks, on the upper side, for example on a head part.
  • Four engagement elements are preferably provided per first or second formwork support in order to be able to attach up to four formwork elements to the same first or second formwork support.
  • the concreting position can be horizontal.
  • the formwork element can also be inclined in the concreting position.
  • the angle of the formwork element to the horizontal in the concreting position is smaller than in the inclined intermediate position.
  • the first and / or second mount of the formwork frame preferably has a holding projection or a holding opening.
  • the retaining projection or the retaining opening is connected to a corresponding engagement element at the upper end of the formwork support.
  • the first holder and / or the second holder preferably each have two holding projections or holding openings in order to enable the first or second cross member to be connected to two formwork supports.
  • the retaining opening can be formed by a recess in the first or second cross member.
  • the retaining projection can be designed as a hook.
  • the connecting web is connected to the first and second cross members so as to be displaceable in the transverse direction.
  • transverse guides are provided on the first and second transverse support, which enable the transverse displacement of the connecting web.
  • the connecting web in the basic position is essentially the same distance from both longitudinal sides of the formwork frame (ie from the ends of the first or second cross member), so that the formwork frame is I-shaped in plan. Starting from the basic position, the connecting web can be directed to a long side and / or to other longitudinal side of the formwork frame to be moved to the first or the second recess for receiving an obstacle, such as a support, to enlarge accordingly.
  • the connecting web is formed by a double web.
