Definitions

  • the invention relates to a permanent formwork for a concrete ceiling, from at least two adjacent, prefabricated, assembly-resistant plate elements made of concrete according to the preamble of claim 1. Furthermore, it relates to a method for producing a plate element and an anchor for the formwork.
  • Prefabricated panel elements are manufactured in a central location in a size suitable for transport, for example in dimensions of 2 mx 5.20 m or 1 mx 5.20 m. They are usually 4 cm thick and, in addition to the static reinforcement, also contain stiffening reinforcement in the form of lattice girders protruding from the slab.
  • the panels are brought to the construction site and form permanent formwork for the production of ceilings.
  • such plate elements are placed next to each other on the retaining walls, where necessary mounting supports are attached and poured in-situ concrete at the required height.
  • different deflections can occur between adjacent plate parts, which lead to a visible step on the underside of the finished ceiling. To avoid this, additional assembly supports must be installed.
  • the provision of additional assembly support which can only be removed again when the in-situ concrete of the ceiling has hardened, requires a substantial amount of effort.
  • the object of the invention is to avoid this effort, i.e. with the usual ceiling dimensions without additional installation supports or with larger dimensions with considerably fewer installation bases. This should ensure that when concreting the ceiling adjacent plate elements in the area of the butt joint can not bend to different degrees, so that a perfect view of the finished ceiling is guaranteed.
  • the plate element for the formwork according to the invention has at least one anchor in the region of the abutting edge adjoining the adjacent plate element, which can be non-positively connected to the corresponding anchor of the adjacent plate element by a connecting member, so that here a connection point is created in a simple manner capable of shear forces from that to transfer one plate element to the other plate element and thus prevent a different deflection of the plate elements at this point.
  • the positive connection must take into account on the one hand the fact that the thickness dimensions of the two plates in the area of the connection point are somewhat different for manufacturing reasons and it must also be possible to transmit transverse forces acting both upwards and downwards.
  • the latter requirement takes into account the fact that it cannot be determined from the start to which of the plate elements a load is initially applied.
  • connection points formed by anchors and a connecting element can be provided along the butt joint of two adjacent plate elements. So that these can be realized by uniform plate elements, the position of the armature is preferably chosen to be axially symmetrical.
  • Fig. 1 shows a top view of three adjacent plate elements 1, 2 and 3 made of concrete, which are placed on retaining walls 5, 6 and 7 and form the permanent formwork for a concrete floor.
  • each plate element also contains stiffening reinforcement, preferably made of lattice girders, which are indicated by dash-dotted lines 8 in the plate element 1.
  • stiffening reinforcement preferably made of lattice girders, which are indicated by dash-dotted lines 8 in the plate element 1.
  • Each line should represent a lattice girder.
  • each plate element carries at least one anchor 10 for the positive connection of a connecting member 11 (see FIG. 2) between the two anchors 10.
  • a connecting member 11 see FIG. 2
  • the anchors consist of a foot part, which in the present case is designed as a plate 14 and anchored in the concrete of the plate element 1 or 2, and a head part which is non-positively connected to the foot part and which consists of the plate top 15 protrudes and is formed in the embodiment by a closed bracket 16.
  • the U-shaped bracket in this case is welded to the plate 14 with its two legs.
  • the connecting member 11 is wedged both on the plate element 1 and on the plate element 2.
  • the wedges 17 and 18, which are preferably made of wood.
  • the wedges make it easy to compensate for differences in the thickness of the plate elements 1 and 2 in the region of the connection point which are caused by the production.
  • the clear height of the stirrups 16 in relation to the lower edge of the plate elements 1 or 2 need not be observed exactly here, since deviations can be compensated for by the double wedges.
  • the connecting member 11 is then no longer in a parallel plane to the underside of the plates 1 and 2, but this does not impair the function.
  • the anchors 10 are first inserted into the form of these elements at the intended locations and fixed relative to the formwork. Since the underside of the anchors 10 is to be aligned with the underside of the plate elements, these elements are simply placed at the intended location on the bottom of the formwork and the brackets 16 are fixed to the formwork in the area later protruding from the plate surface by means of a suitable clamping device . The remaining reinforcement is then introduced and the plate element is manufactured as usual. After laying such plate elements on the construction site (see Fig. 1), the connecting members 11 are introduced and clamped by means of the wedges 17 and 18.
  • the connecting member 11 is designed in the present case as a round metal rod.
  • other cross-sections can be used for the connecting link and the upper region of the bracket 16 can be adapted to this cross-sectional shape.
  • the clear width between the legs of the bracket is also only slightly larger than the diameter or the width of the connecting member 11. It is below twice the width dimensions of the connecting member.
  • the bracket 16 of the anchor is not arranged directly adjacent to the abutting edge 19 of the plate element, e.g. according to the embodiment according to FIG. 4, but at a distance therefrom, so that in the case of dislocations caused by tolerance during manufacture and during laying, as indicated in FIG. 1 between the plate elements 2 and 3, the connecting member 11 is still inserted into both brackets can be.
  • the foot part 14 of the armature 10 in the illustrated embodiment also forms the underside of the plate element at this point, it should be formed with a non-corroding surface.
  • Galvanized sheet steel for example, is suitable for this.
  • the bracket 16a of the armature 10a is arranged directly adjacent to the abutting edge 19 of the respective plate element 1a or 2a.
  • This arrangement is with regard to the transfer of lateral force from one plate to the other is more advantageous.
  • brackets 16a connected by the connecting member are arranged directly adjacent in the embodiment according to FIG. 4, height differences between the adjacent lower edges of the adjacent plates cannot be compensated to the same extent as in the embodiment according to FIGS. 2 and 3.
  • the two brackets 16a are closely adjacent to one another, their lower edges 20 are brought to the same height by means of the connecting member 11 if the connecting member 11 runs only somewhat parallel to the underside of the plate.
  • bracket 16a by means of the alignment of the lower edges 20 Link 11 also aligned the lower adjacent edges of the adjacent plate elements 1a and 2a, ie there is no observation of the underside of the ceiling when the connecting member is clamped.
  • the head part of the anchor protruding from the top of the plate has a support surface for the connecting link, which in the case of each anchor in the installed state lies at the same predetermined height above the underside of the plate element in question and runs parallel to the underside. If the adjacent contact surfaces of two adjacent anchors are brought to the same level by clamping the connecting member on this support surface, the undersides of the two adjacent plate elements in the region of the two anchors are also forced to the same level, i.e. the two adjacent lower edges close without a difference in height to each other and are held in this position by the shear force-transmitting anchor even under load.
  • the anchor 31 used in the third exemplary embodiment according to FIGS. 6 and 7 and shown in perspective in FIG. 8 contains a foot part composed of at least two anchoring brackets 34 and 35 embedded in the concrete of the plate elements 32 and 33.
  • the anchoring brackets here are also U-shaped. mi a and welded to a hexagon cylinder piece 36, which can also be a tube _, the upper end surface 37 protruding from the top of the plate is designed as a bearing surface for the connecting member 38.
  • the connecting member 38 is clamped onto the bearing surface by means of a screw connection from a threaded bore 39 in the cylinder piece 36 and a screw 40.
  • the connecting member 38 is designed in the form of a tab, that is to say with a mating surface matching the contact surface 37.
  • the connecting member By clamping the connecting member by means of the two screws 40, the bearing surfaces 37 and thus the lower edges of the adjacent plate elements 32 and 33 are brought to the same height. 8 shows, the connecting link 38 has elongated holes 41; around to be able to compensate for the inaccuracies caused by the manufacture and laying of the panel elements.
  • an anchoring bracket namely the anchoring bracket 34
  • an anchoring bracket namely anchoring bracket 35
  • the two brackets take into account the fact that the anchor must be able to transmit transverse forces in both directions. It is also possible to provide only a single anchor bracket if it has a sufficient extent. In this case, the anchoring bracket must be arranged approximately in the middle between the underside of the panel and the top of the panel.
  • the anchor shown in Fig. 9 is characterized by particularly simple manufacture.
  • the foot part is also formed here by anchoring brackets 42 and 43, which, however, are V-shaped here, that is to say they each have only a single bending point.
  • the brackets are welded at a suitable distance to a threaded bolt 44, onto which a nut (not visible in the illustration according to FIG. 9) is screwed, which optionally forms the contact surface for the connecting member 38 with the interposition of a washer.
  • the tab-shaped connecting member 38 can be clamped onto the support surface by means of a further nut 45.
  • the threaded bolt 44 has a screw head at the lower end, then it is expedient to provide spacers 46 on the lower anchoring bracket 42, which ensure that the anchor assumes the correct position on a flat formwork base without special measures. It should also be mentioned that when concreting the plate element, the thread is preferably covered by a plastic cap.
  • the anchor of FIG. 10 differs from that of FIG. 9 in that the lower anchor bracket 47 is U-shaped.
  • the base part of the anchor is formed from a plate 51 or 52 anchored in the concrete by claws 50 and arranged on the abutting edge of the plate element.
  • the plate 52 is bent inwards at both ends in order to ensure an even better anchoring in the concrete.
  • the outside of the sheet metal strips 51 and 52 which is not visible in FIGS. 11 and 12, lies in the same plane as the surface of the abutting edge of the associated plate element.
  • the angled ends of the sheet 52 are countersunk in the associated plate element.
  • a threaded bolt 53 is also provided as the head part.
  • the lower edges of the plate elements are forcibly aligned in that the contact surfaces of the adjacent anchors are brought to the same level by clamping the connecting member.
  • the smaller the distance between the adjacent contact surfaces the more favorable it is. is the distance between the head parts of the two anchors.
  • the embodiments shown in FIGS. 11 and 12 are therefore also more suitable in terms of alignment than the embodiments shown in FIGS. 9 and 10.
  • the distance between the contact surfaces i.e. between the threaded bolts 44 of adjacent anchors, by welding the threaded bolts not outside the anchoring bracket but outside the same. This position is indicated in dashed lines in Fig. 10 and designated 44 '.
