Definitions

  • the invention relates to a formwork element for the shell concrete construction, in particular made of rigid foam, according to the preamble of claim 1.
  • a formwork element is known from DE-U-7 120 078.
  • Known large-sized formwork elements (DE-B-26 18 125) can be used in a variety of ways in a network and enable cost-effective and fast construction of buildings with good external and internal thermal insulation.
  • a formwork element for the shell concrete construction made of rigid foam with side walls is already known, which are provided at their edges with grooves and tongues for securing the position and can be connected by webs, the side walls being provided with snap-in points on their inside , on which the webs can be positioned.
  • the connecting elements are inserted with T-shaped or L-shaped grooves with transverse profiles and can only absorb relatively low compressive forces.
  • DE-U-7 625 460 a prefabricated element with at least two mutually parallel and spaced plates made of, for example, clamping material is known, in which the plates are connected by spacers to plate-like extensions by gluing.
  • the spacers are made of steel and are directly bonded to the panels in a dimensionally stable manner.
  • the formwork elements should be stable and resistant to internal and external loads with regard to the often storey-high concrete backfilling, and should allow for cheap manufacture and space-saving transport.
  • the invention is therefore based on the object to formwork elements for the shell concrete construction create that can be used universally, can be produced cheaply with short cycle times, can withstand high loads, especially when filling with concrete, require little transport and storage space and can also be used as insulation boards for a wide range of uses.
  • the material of the connecting bridges can also be chosen so that the dreaded acoustic bridges are avoided and the clairaudience of the buildings can be eliminated.
  • the snap-in points are undercut by a shallow depression Edges are formed, into which an adapted counterpart can be inserted in a latching manner.
  • the snap-in points can also be formed by a flat elevation with retracted edges onto which an adapted counterpart can be latched.
  • a snap-in or clip connection is then created between the side wall on the one hand and the connecting elements or other parts on the other hand, which pulls the two parts against one another.
  • an adhesive can be applied or sprayed on before snapping into place.
  • the depression or the elevation can be relatively flat, for example a height or depth of 2 to 5 mm, so that there is practically no weakening of the side walls.
  • the shape of the depression or elevation and the corresponding counterpart can be selected depending on the circumstances. However, a circular shape is particularly useful.
  • the locking points are formed by a ball socket or a ball for locking a ball or a ball socket.
  • the ball or the ball socket can be arranged on an elevation or at the bottom of a depression, which expediently has a circular shape.
  • the connecting webs each have a contact surface at both ends, which are designed as a counterpart to the elevation or depression and / or the ball or ball socket, it is possible to additionally and extensively glue the surfaces lying against one another.
  • the ball and the ball socket should be designed so that a certain amount of tension remains after the assembly, which ensures secure contact and a good glue point.
  • the contact surfaces can be provided with extensions that extend beyond the elevation or depression.
  • the latching points can also be formed by grooves arranged at the same distance from one another, running from top to bottom and distributed over the entire inner surface of the side walls.
  • the cross section of the grooves can be rectangular or so be that the grooves are widened at their base, for example, have the shape of a dovetail.
  • Formwork elements designed in this way can be manufactured with practically any desired length or cut to the required size.
  • the grooves improve the adhesion of the side walls to the concrete, so that the penetration of water into the gap between the side wall and the concrete is prevented and, moreover, no tones can occur when the side wall strikes the solidified concrete.
  • the recess in the grooves creates webs between two adjacent grooves, the cross-section of which can advantageously be complementary to the cross-section of the grooves.
  • the tongue and groove surface of the side walls has a shock-absorbing effect when pouring the concrete, which often falls from a relatively high height. Individual chunks are then spring-loaded and do not lead to the formwork elements being destroyed by bursting.
  • the side walls are preferably made of rigid foam. However, other materials can also be used. In particular, it is possible to connect side walls of different types to one another. For example, a hard foam side wall can be used on the outside of a building and a gypsum fibreboard can be used on the inside. Other combinations, also with mineral insulating materials, are possible.
  • the material of the connecting webs is expediently chosen so that a good connection is achieved and there is no risk of fire breakdown.
  • lightweight concrete (vermiculite) is also suitable. When, for example, rigid foam and concrete are bonded, curing times are considerably shorter than with a bond between two hard foam parts because the solvents can escape from the bond point more quickly.
  • the connecting webs can have one or more reinforcing bars in the central area, which are either exposed or already cast with concrete.
  • Concrete connecting webs can also have coaxial bores from both ends, which are in one end a short distance from each other. The remaining concrete residue between the two bores prevents fire penetration, but on the other hand can be easily pierced later, for example for the convenient attachment of fastening or support parts and also for the passage of lines and pipes. Finding the correct point is particularly easy when the side walls have centering points on their outside which identify the position of the connecting webs and, if appropriate, their bores.
  • the shaft can have at least one circumferential groove at the transition to the end plates. Reinforcing bars can be inserted correctly positioned in this groove. Two adjacent grooves allow such bars to cross.
  • the snap-in points are formed by grooves arranged at the same distance from one another, running from top to bottom and distributed over the entire inner surface of the side walls, the contact surfaces on the end plates of the connecting webs have an adapted shape with alternating grooves and tongues. Even if the grooves in the side walls are undercut, the corresponding tongues of the end plates can have a rectangular or square cross-section so that they can be easily inserted. A high degree of strength is achieved through large-area gluing. Because of the continuous grooves on the side walls, the connecting webs can be attached at the desired height and at any point. If the end plates are attached in such a way that they bridge the vertical or horizontal gap between formwork elements, they also serve to connect adjacent elements. Several formwork elements can be connected at the joint between a horizontal and a vertical gap.
  • the outside of the side walls can be provided with a raised or recessed grid, which enables parts of the formwork elements to be cut to size on the construction site.
  • a cross grid or a pattern of parallel vertical lines can be provided.
  • the depth of the corresponding channels or the height of the corresponding webs only has to be so large that a correct detection is possible.
  • the formwork elements according to the invention can be adapted to all practical requirements with the help of only one type of side wall, associated connecting webs and only one end wall. So there is no need to use special corner elements and other connecting elements of different shapes.
  • a fire-retardant rigid foam of class F is used to eliminate the risk of fire.
  • FIG. 1 The embodiment of a formwork element according to the invention shown in perspective in FIG. 1 has two side walls 10 made of fire-retardant rigid foam, which are connected to one another via two webs 11 and an end wall 12.
  • the upper and lower edges as well as the front edges of the side walls 10 and the upper and lower edges of the end wall 12 are provided with webs 13 or complementary grooves 14 which are circular in cross section with a short approach are trained.
  • To assemble the springs 13 are inserted into the grooves 14.
  • On the outside of the Sidewalls 10 are arranged in the form of flat grooves 16, which enable a cut to size. Centering points 17 mark the position of the connecting webs 11.
  • Fig. 2 shows in more detail an embodiment for the latching point between the side wall 10 and a connecting web 11.
  • the side wall has a flat recess 18 with an undercut edge, and the foot 19 of the connecting element 11 has a complementary elevation 20 with a retracted edge, which is located below Snap or snap into the recess 18.
  • the shape is such that a certain amount of tension remains after clipping in and thus the connecting web 11 is held securely against the wall 10. If you glue the surfaces that are next to each other with adhesive before clipping in, this results in a very secure and tensile connection.
  • FIG 3 shows a complementary embodiment of the connection point between the connecting web 11 and the side wall 10.
  • the foot 19 contains the shallow depression 18 and the wall 10 the corresponding elevation 20.
  • FIG. 4 Another embodiment for the connection between the side wall 10 and the connecting element 11 is shown in FIG. 4.
  • the foot 19 of the connecting web 11 has a flat, central depression 21, and the wall 10 is equipped with a corresponding elevation 22.
  • a ball 23 is arranged in the center of the depression 21 and engages in a ball socket 24 by being pressed into it.
  • a residual tension is exerted on the connecting element 11 after it has snapped in, so that a secure fit and good adhesion is achieved.
  • the foot 19 of the connecting web 11 can be provided with extensions 25 indicated by dashed lines.
  • connection elements 11 arranged one above the other are in accordance with the exemplary embodiment according to FIG. 2 by snapping in with the side walls 10 connected.
  • the connecting elements 11 consist of concrete and have central bores 26 from both sides, which end at a distance of a few centimeters from one another.
  • the centering points 17 on the outside of the side walls 10 mark the position of the holes 26, so that later the remaining residue between the two holes 26 can be drilled through for the passage of lines or cables or the attachment of fastening and supporting elements.
  • the side walls 10 alternately have grooves 60 on their entire inside, which are widened at their base and thus have the shape of a rounded dovetail.
  • the webs 61 between adjacent grooves 60 have a cross section that is complementary to the grooves 60.
  • the associated connecting webs 11 are expediently made in one piece from concrete. They have plate-shaped end plates 62, the outer surfaces of which have webs 63 which penetrate into the grooves 60 and grooves 64 which receive the webs 61.
  • the webs 63 which can be continuous or interrupted, have a rectangular cross section, so that the connecting webs 11 can be inserted into the side walls 10. This can be done practically anywhere and at any height of the formwork elements.
  • a very high strength of the connection point between the connecting webs 11 and the side walls 10 can be achieved by using a suitable adhesive.
  • FIG. 7 shows examples of the possibilities that are created with the design of the side walls 10 and connecting webs 11 in accordance with the exemplary embodiment according to FIG. 6.
  • No specially designed formwork elements are required for the corner connection according to FIG. 7. It is only necessary to cut out part of the side wall 10 at the point designated 65, so that no bridge consisting of rigid foam remains in the later finished wall, which enables fire penetration.
  • the connecting webs 11 are moved as close as possible to the corner, and - as shown - they can also protrude into the opening 65.
  • the lowest connecting web 11 in FIG. 7 bridges the gap between two formwork elements and accordingly establishes a connection.
  • An end piece 66 closes off the corner from the outside.
  • FIG. 8 shows a T-shaped connection point between formwork elements according to FIG. 6. Again, no special designs are required. It is only necessary to remove part of the side wall 10 at the joint at 67 so that there is again no risk of fire breakdown. The connecting webs 11 are brought close to the point 67 in order to achieve the required strength or project into this.
  • FIG. 9 schematically shows a ceiling finish using formwork elements according to FIG. 6.
  • the upper part of the side wall 10 is removed from the uppermost formwork element at 69 in accordance with the thickness of the dashed line 68 shown in dashed lines up to the height of the filled-in concrete 70.
  • the protruding part of the end plate 62 of the uppermost connecting web 11 can be knocked off, if necessary.
  • the connecting web 11 at the transition to the end plates 62 has two circumferential grooves 71 on both sides. Horizontal and / or vertical reinforcing bars 72 can be inserted into these.
  • an adhesive which contains a solvent for polystyrene in an appropriate dilution, the dilution being selected such that the cell walls of the polystyrene are only dissolved and softened to such an extent that the surface of the polystyrene is smoothed and adjusted to the surface of the webs is made possible without the cell walls of the polystyrene collapsing.
  • This dissolving of the cell walls in the surface area of the rigid foam surprisingly leads to a solidification of the surface of the formwork element, since the rigid foam balls from which the rigid foam is made bake together, so that a welded surface layer of the rigid foam is produced in the area of the adhesive point.
  • the adhesive used it is important to use the solvent of the rigid foam in a controlled manner. This generally requires dilution with a filler or the like based on cellulose, acrylic resin or polyester resin. can exist. This filler also has the function of filling any gaps between the formwork element and the webs.
  • the consistency of the adhesive can be adapted to the application process, with spraying, brushing and filling.
  • glue can be applied to either the web or the rigid foam or to these two parts.
  • the adhesive applied to the webs can differ from the adhesive applied to the rigid foam, in particular it can be portions of a two-component adhesive. If both sides of the surfaces to be glued are treated with glue, then the consistency of the glue for one Side, for example the webs, on the consistency of the adhesives on the other side, ie the rigid foam, may be different. For example, one side to be glued is sprayed with an aerosol, while the other side is coated with a paste, which ensures surface leveling between the surfaces to be glued.
  • the formwork system for the sheath concrete construction can be supplemented by a further element, not shown, whereby in particular horizontal formwork end walls can be formed.
  • This element has snap-in points on its narrow sides which correspond to the corresponding snap-in points 18, 20, 23, 63, 64 of the webs and thus can cooperate with the snap-in points 18, 20, 24, 60, 61 of the wall formwork elements.
  • These formwork elements provided to form a horizontal formwork end wall have a width which corresponds to the length of the connecting webs 11, while the length of these elements is not critical and can be, for example, 1 m, since one can form a horizontal formwork end wall from individual pieces.
  • these formwork elements expediently have tongue and groove on their small narrow sides, which can have the design according to parts 13, 14. In this way it is possible to put together a continuous, horizontal formwork end wall from individual formwork elements.
  • Such a horizontal formwork wall is inserted into the vertically running snap-in points of the narrow sides of the side wall formwork elements 10 and held by support.
  • the advantage is that the horizontal formwork end wall can be moved up or down as far as the height of the window opening or door opening corresponds. It is understood that the horizontal formwork end wall is supported in a known manner from below when casting the lintel.
