Definitions

  • the invention relates to a formwork system for a cycle sliding formwork according to the preamble of claim 1.
  • Such a formwork system is known from EP-A-0 350 525.
  • the way to create building walls made of concrete is to provide climbing formwork with several formwork fields arranged vertically one above the other. These formwork fields are anchored in the wall by means of cross anchors, which are held in plastic pipes that remain in the concrete. After the concrete has set and solidified between the upper formwork fields, the lower formwork fields or formwork panels are loosened and installed as topmost new formwork fields.
  • a sliding scaffold is used that can slide upwards using a climbing pole and a lifting device.
  • the yoke scaffold has a yoke leg on both sides of the building wall, which are connected in the area of the lifting device by means of a yoke traverse.
  • the individual working platforms are attached to the yoke legs, with transverse stiffeners arranged in the direction of the building wall, which bear against the vertical girders of the formwork fields and slide upwards thereon.
  • Another formwork system is known from DE-A-19 43 365.
  • this formwork system a combination of climbing formwork and sliding formwork is used, the yoke frame being stabilized as a double frame in the manner of a non-positive parallelogram.
  • the aim of this last-mentioned formwork system is precisely to make a structure of the individual formwork fields on the concrete wall surface clearly recognizable, for which purpose the arrangement of tubular moldings, e.g. operated in the horizontal direction along the joints of the formwork fields, if necessary also in the vertical direction.
  • Anchoring should also be provided, at least for the yoke leg carrying the climbing formwork.
  • FR-A-1 300 200 describes climbing formwork whose implementable formwork walls are held by a scaffold with supports that are parallel to one another.
  • the supports are supported by a three-point bearing on the lower, solidified concrete wall.
  • the vertical supports are held by a bracing device, which consists of an upper and lower cross connection.
  • the cross connections are articulated on the vertical supports and have a central threaded spindle with which the distance of the parallel supports can be adjusted.
  • the formwork walls are held in pairs by upper and lower spindles, which are fixed in the vertical supports.
  • the object of the invention is to improve a formwork system of the generic type in such a way that an easier cycle sliding method is achieved in climbing formwork while maintaining safety requirements, with the labor and materials used particularly with regard to the anchorage can be reduced noticeably.
  • the yoke frame is equipped on each side with the actual yoke, which has an inner yoke leg.
  • This inner yoke leg which is expediently a square steel tube, is non-positively connected to a formwork anchor device via the yoke traverse.
  • an outer yoke leg In order to be able to optimally transfer the transverse forces for bracing from the yoke scaffold to the upper formwork fields
  • an outer yoke leg In the horizontal direction adjacent to the inner yoke leg on both sides, an outer yoke leg is provided, which is designed as a unit via cross struts or cross members.
  • One or more cross anchors are provided on a cross strut at about half the height of these outer yoke legs, which are to be referred to as a yoke pair, and have their counterbearing on the outside of the opposite outer yoke legs.
  • the transverse stress applied by the anchor is released and the entire yoke structure is raised in a sliding manner.
  • the lower formwork panels are then transferred as the new top formwork panels, with the cross anchors of the yoke scaffolding again lying above the upper formwork edge.
  • the cross anchors are then prestressed again against the vertical supports of the uppermost formwork panels, in the meantime the retaining cones of the formwork panels underneath ensure secure, albeit slight anchoring to the concrete wall of the building.
  • the foot-side end of the yoke frame is advantageously in the upper area of the already solidified concrete wall, so that when the concrete is inserted between the uppermost formwork panels, the required transverse forces can be optimally adjusted by an approximately central deflection of the outer yoke legs in the region of 1.5 cm.
  • the cross anchor of the yoke frame is expediently a round steel or round bar that has an external thread on both sides for screwing with nuts.
  • the cross anchors can be designed as hydraulic presses which engage the yoke legs in a force-fitting manner and which also control the necessary forces via the round or tensioning arms connecting the yoke legs to the yoke frame.
  • the outer yoke legs are designed as U-beams with a U opening facing away from the inner yoke leg.
  • a plate-shaped stiffening iron is expediently attached in the U-shape.
  • the outer yoke legs are connected to each other approximately in the middle via an anchor crossbar to ensure uniform force transmission.
  • the anchors themselves are therefore placed on this anchor cross iron, the distance between the anchors being kept such that the inner yoke leg and the climbing pole come to rest with play.
  • outer yoke legs which are used solely for transverse anchoring, are supported on the head side with a cross bearing opposite the yoke cross member and on the foot side with a system against the cross beam, e.g. lower cross member designed as a square steel tube.
  • a vertical support for the outer yoke legs is created on the head side opposite the inner yoke.
  • An outer pair of yoke legs rigidly connected to one another is therefore freely adjustable in the transverse direction via the cross anchor, with a swivel area on the head side in the area of the yoke traverse and the upper end of the inner yoke leg.
  • the formwork system according to the invention can be used not only with largely linear building walls, but also with rounded, ring-shaped or circular or polygonal buildings.
  • a yoke scaffold 1 is shown at the upper end of a building wall 6 made of concrete, which is part of a tact-slip formwork system, which also has a climbing formwork 2.
  • the climbing formwork 2 consists of three formwork panels 4 arranged one above the other, which are fixed to one another by means of vertical supports 5.
  • the vertical supports 5 are, for example, square steel tubes which interlock positively and are wedged against one another in the transition region by means of a cross wedge 17.
  • each formwork panel 4 has a holding cone 15 in the lower area, which e.g. consists of hard rubber and can have a hemisphere or truncated cone shape.
  • the yoke scaffold 1 is provided.
  • the yoke frame 1 essentially consists of an upper yoke cross beam 21, which is usually formed from two U-beams, which accommodate a lifting device 8 in their intermediate space.
  • an inner yoke leg 22 is connected to the yoke traverse 21 on both sides of the building wall 6 in a non-positive and in particular rigid manner via an upper angle iron 35.
  • This inner yoke leg 22 is normally a square tube, in the lower region of which, facing the building wall, cross struts or cross members 31, 32 and 33 are welded. These cross struts 31, 32 and 33 run approximately horizontally and lie on the outer surface of the vertical supports 5.
  • a further angle iron 47 is provided on the foot side for better stiffening between the inner yoke leg 22 and the lower cross member 31.
  • An upper work platform 51 is also indicated in FIG. 1, this and a lower work platform (not shown) usually being carried by the inner yoke leg 22.
  • the yoke frame is now equipped with a formwork anchor device.
  • FIG. 3 shows a side view, e.g. from the right, onto the yoke frame according to FIG. 1.
  • This formwork anchor device essentially consists of two outer yoke legs 23 arranged parallel to the inner yoke leg 22. These yoke legs 23 are vertically on the inside of the head by means of an angle iron 45 Yoke leg 22 mounted and supported inward over the further angle iron 35.
  • these two outer yoke legs 23, which are rigidly connected to form a unit, have a lower crossbar 38, a central crossbar 37 and an anchor crossbar 36 set at half height, which is designed as a square tube.
  • two anchors 40 e.g. made of round steel, attached in the transverse direction. These anchors 40 protrude through the anchor holes 54 and 55 (FIG. 3) and are non-positively designed on the outside by means of nuts 41 for the transverse application of the outer yoke legs 23.
  • stiffening irons 43 are welded in plate-like manner in the area of the anchors 40.
  • These plate-like stiffening irons 43 extend between the legs 26 and 27 of the U-beams.
  • Below the cross iron 36 is another, middle cross iron 37, which is also a square tube.
  • a screw bolt 42 extends through and lies on the foot side against a stop plate 49, which is located on the outside of the inner yoke leg 22, e.g. is welded on.
  • set screws 52 are provided over crossbars 53 in the upper region, which are in engagement with the yoke traverse 21.
  • the outer yoke legs 23 therefore represent formwork anchor devices which can be acted upon by force independently of the inner yoke leg 22.
  • the outer yoke legs 23 are therefore prestressed inward in the direction of the building wall via the anchors 40 and their nuts 41 in order to adjust the transverse forces and for support on lower vertical supports .
  • the crossbeams 31 to 33 thus come into contact with the vertical beams 5 of the uppermost and, in the example, the next lower formwork field.
  • a slight deflection of the outer yoke legs in the range of 1 to 2 cm in the central area occur.
