Definitions

  • the invention relates to a formwork element for the shell concrete construction, in particular made of rigid foam, with side walls, which are provided at their edges with grooves and springs for securing the position and can be connected by webs and, if appropriate, end walls.
  • Known large-format formwork elements of this type can also be used in a variety of ways in composite structures and enable cost-effective and quick construction of buildings with good external and internal thermal insulation.
  • improvements are desirable.
  • the formwork elements should be stable and resistant to internal and external loads with regard to the often storey-high concrete backfill, and should enable cheap manufacture and space-saving transport.
  • the invention is therefore based on the object to provide formwork elements for the sheath concrete construction, which 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 Allow many uses.
  • the invention is based on a formwork element of the type mentioned at the outset and is characterized in that the side walls are provided on their inside with snap-in points at which the webs can be fixed in position.
  • a material of high strength and heat resistance can be selected for the connecting webs, for example reinforced concrete, so that the side walls withstand a high internal pressure when filling the concrete.
  • connecting webs made of hard foam for example, in the case of one-piece production of the formwork elements, the penetration of a fire is avoided.
  • the storage and transport costs remain low because the individual parts first have to be assembled at the construction site or in a regional interim storage facility. This is in contrast to also known formwork elements (US Pat. No. 4,223,501), in which connecting webs in the form of metal grids or sheets are inserted into the mold during manufacture.
  • 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 formed by a shallow depression with undercut edges, into which an adapted counterpart can be inserted in a latching manner.
  • the locking points can also be replaced by a shallow elevation with indented edges are formed, on 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 chosen depending on the circumstances. However, a circular shape is particularly useful. But there is also the possibility of forming the recesses as a tongue or groove with a dovetail cross section. One or more grooves or tongues can run through to the upper edge and / or to the lower edge of the side walls, so that the corresponding counterpart can be inserted. The remaining parts of the grooves or tongues lead to an additional anchoring of the side walls on the concrete without additional measures. The attachment is also ensured if the glued joints between the side walls and the connecting webs no longer hold. For the correct positioning of the connecting webs or other counterparts, the groove or the tongue can be provided with centering points.
  • 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, there is the possibility of contacting one another Additional surfaces to be glued together over a large area.
  • 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 may be used for other V ER- enlargement of the adhesive surface be provided with extending beyond the elevation or depression extensions.
  • 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 designed that the grooves are widened at their base, that is to say, for example, in the form of a dovetail.
  • Formwork elements designed in this way can be manufactured with practically any desired length or cut to the required size, as required.
  • 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 arise 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 appropriately chosen so that a good connection is achieved and there is no risk of fire breakdown.
  • a further development of the invention recommends that the connecting webs consist of concrete at least in the area of their contact surfaces. Lightweight concrete (vermiculite) is also suitable here.
  • the connecting webs can have one or more reinforcing bars in the central area, which are either exposed or already cast with concrete.
  • the connecting webs made of concrete can also expediently have coaxial bores from both ends which end at a short distance from one another. The remaining concrete residue between the two holes prevents fire penetration, but on the other hand can easily be pierced later, for example for convenient attachment of fastening or support parts as well as for the passage of lines and pipes. Finding the right place is particularly easy when the side walls have centering points on their outside. which marks the position of the connecting webs and, if applicable, their bores.
  • Connecting webs made in one piece from concrete have plate-shaped end plates on both sides, which are connected via a central shaft.
  • the plate-shaped end plates suitably have a circular shape, but can also be oval, rectangular or any other shape.
  • 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 contact surfaces of the connecting webs are expediently designed as a counterpart to the latching points on the side walls in order to achieve a good connection.
  • the latching 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 connecting webs can also be realized in the form of two plates forming the contact surfaces, which are connected via preferably crossed tension struts in the form of wires or flat elements. It is important to achieve a certain spring effect, which helps to avoid sudden loading of the side walls when pouring concrete and thus avoid tearing out the connecting webs from the side walls.
  • the side walls in a further development of the invention can be provided on their inside with trough-shaped depressions or web-like elevations, preferably running parallel to the narrow sides of the side walls. Elevations are particularly suitable if the latching points of the side walls also have elevations, so that the thickness of the side walls and thus the storage and transport space used do not increase additionally. In the other case, ie if the snap-in points have depressions preferably also groove-shaped depressions.
  • the side walls can be provided on their outside 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 grooves and tongues provided on the edges of the side walls for securing the position are undercut according to a particularly advantageous development of the invention, so that a tensile connection between adjacent side walls is created.
  • the springs can be dovetail-like with correspondingly adapted grooves, rounded edges being expedient. There is also the possibility that the springs in cross section have approximately the shape of a circle, which is connected to the side wall via a short extension.
  • the grooves are complementary. Such a rounded design has the advantage that dirt caused by concrete residues can be removed more easily in rough operation on the construction site.
  • the locking points can also be realized in that the side walls at the top and bottom edge have blind holes with a T-shaped cross section open to the inside for the latched reception of end plates of the connecting webs.
  • the blind holes can be relatively close to the inner surface, so that there is no major weakening of the side walls.
  • the depth of the blind holes can correspond to half the dimensions of the end plates Chen, so that the end plates are each arranged half in a formwork element and the other half in the formwork element above.
  • the end plates expediently have a square shape and are connected by a rectangular bar. Then the connecting webs can be rotated alternately by 90 ° with each other, whereby a higher torsional rigidity is achieved.
  • the cross section of the blind holes must then be adjusted accordingly.
  • the end plates can be made of sheet metal, for example.
  • the connecting rods can be welded wires.
  • a further development provides that two connecting webs, each with two end plates, are connected to one another in the region of their connecting rods between the end plates. If the connection is made in the middle of the connecting rods, an X-shaped structure is created, which in turn has a certain spring effect. In addition, the distance between two double connecting webs of this type is increased in the middle of the respective wall, as a result of which pipes of larger cross-section (for example with a diameter of 100 mm) can be accommodated without difficulty.
  • 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.
  • the side walls can be used as thermal insulation panels.
  • Such insulation boards can be installed as roof insulation boards on or under the rafters.
  • the positive connection enables fast and clean work.
  • the panels can have a relatively long length of, for example, 2 m, because the formwork elements can also be large.
  • the thermal insulation boards can be laid on floating screed and, if necessary, carry pipes or hoses for underfloor heating.
  • the thermal insulation panels can also be attached to the outside or inside of buildings.
  • 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, in the case of roof insulation panels the grooves are arranged upwards and in the direction of the roof , so that penetrating or condensing water can run off to the eaves.
  • the tongue and groove side is brought down to enable better impact sound insulation.
  • the grooves also enable the side walls to be retrofitted as interior or exterior wall insulation when using plaster or adhesive mortar.
  • holders can also be used which are designed as one end of the connecting stele, cooperate with the snap-in points of the thermal insulation panel in the form of the side wall and can be fixed on the wall.
  • the right one Positioning of the holders are appropriately used templates.
  • the holders advantageously have a contact surface with a ball on one foot, which snap into ball sockets on the side walls. If the heat insulation plate in the form of the side wall is used as an insulating plate for underfloor heating, holding devices for the pipes or hoses of the underfloor heating are expediently used, which are designed like one end of the connecting webs and interact with the latching points.
  • the holding devices can have a ball which snaps into a ball socket of the side wall or heat insulation plate and which merges into a head provided with a bore for the hose or the pipe, the ball extending into the Has hole through slot.
  • the holder can then be bent open in the area of the slot, placed over the pipe or hose and then snapped into the ball socket.
  • 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 hard foam, which are connected to one another via two webs 11 and an end wall 12.

  • the foot 19 of the connecting element 11 has a complementary elevation 20 with a retracted edge, which can be snapped or clipped into the recess 18 by snapping.
  • 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.
