  • so-called formwork cores are used for the shaping of prefabricated parts, in particular in the preparation of contiguous prefabricated parts, in which at least one bottom part and one side part are connected to one another.
  • An upwardly open external formwork comprising a bottom, two longitudinal walls and two arranged at the front ends of the longitudinal walls end walls, serves as an outer boundary for the walls or building parts to be created.
  • a formwork core is used whose dimensions are slightly smaller than the inner dimensions of the outer formwork.
  • the distance between the walls of the outer formwork and the formwork core corresponds to the width of the side wall to be concreted
  • the distance of the bottom of the formwork core from the formwork floor of the outer formwork corresponds to the thickness of the floor to be concreted.
  • the formwork core is supported on the outer formwork. Parts with complex geometries, such as For example, room modules with floor and side walls or partially closed rooms, can be produced in a concreting process.
  • the inner formwork core can be easily removed from the finished concrete part after the setting process of the concrete, it must be able to reduce its outer dimensions.
  • a manufacturing method using a so-called shrink core for molding is known, which can reduce its outer dimensions after the setting process of the concrete, so that a simple removal is possible.
  • a complex, many mechanical and hydraulic components comprehensive hydraulics is arranged within the core, with the side walls translationally, ie parallel, can be moved inwards.
  • four L-shaped corner pieces are provided, which can slip past each other, so that the corner parts are moved inward.
  • a formwork core according to the preamble of claim 1 in which the side walls can be moved parallel inwards, is also from the FR 2 310 454 known.
  • the formwork core on an inner core are hinged to the four side walls and four corner elements. Lifting the inner core causes the sidewalls to move inward.
  • a prefabricated concrete floor element is present, on which the side walls are concreted.
  • this device is only partially suitable to produce exposed concrete parts in high quality.
  • the present object is achieved with a formwork system having the feature according to claim 1.
  • the present object is also achieved by a method with the features of claim 13 and with the features of claim 14.
  • preferred embodiments of the formwork system according to the invention are defined, which can be used individually or in combination.
  • the formwork system according to the invention for concreting precast concrete elements and room modules comprises an outer formwork and a formwork core.
  • the outer formwork has a formwork floor, two longitudinal walls and two end walls. The end walls are arranged between the longitudinal walls at their front ends, so that there is a cavity-forming, open to the top cuboid structure.
  • the formwork core is used for concreting an upwardly open space module in the outer formwork. The resulting between the outer formwork and the formwork core cavity is filled with concrete.
  • the shuttering core itself forms a cuboid with a horizontal element formed as a base and with a cover element and with at least four vertical elements, two of which are designed as end elements and two as side elements.
  • Each of the vertical elements is coupled to each of the two horizontal elements and movably connected.
  • Each end element is thus coupled to both the cover element and with the bottom of the formwork core.
  • a coupling mechanism is provided, which is designed such that a vertical movement of a horizontal element (bottom or cover element) outwardly causes a movement of the vertical elements in the inward direction, that the distance between the opposing vertical elements is reduced.
  • a lifting of the cover element thus causes the vertical elements to move inwards. The distance between the two end elements and the distance between the two side elements is thereby reduced.
  • the outer formwork and the formwork core can be removed from the concrete part.
  • the formwork core in its dimensions, at least in its horizontal dimensions, shrunk.
  • shrink core By automatically varying the distances of the vertical elements to one another by lifting the cover element, the dimensions are reduced in a simple manner. Thus, it is not necessary to dismantle the formwork core.
  • the coupling mechanism comprises a plurality of pivot levers. At least one pivot lever is arranged between a vertical element and a horizontal element.
  • the pivot lever is articulated to both the horizontal element and on the vertical element.
  • the pivot lever may consist of a connecting piece or a molded part which is fastened between the two pivot points on the vertical element or the horizontal element.
  • a movement of the vertical elements can be generated inwardly such that the movement has a rotational component.
  • a horizontal element is moved outwardly, the edge regions of the vertical elements adjacent to the moving horizontal element are moved towards one another.
  • the pivot lever thus performs a rotational movement. This can take place around one of the bearing points on the vertical element or on the horizontal element. However, pivoting about another within or outside the pivot lever lying (virtual) pivot point is possible.
  • the movement of the pivoting lever caused by moving the horizontal element outwards causes the moving horizontal element to move adjacent edge regions of the two opposing vertical elements are moved towards each other. The distance between these edges opposite edges, however, remains unchanged.
  • the vertical elements are therefore tilted inwards.
  • the tipping of the elements has the advantage that the vertical elements do not have to be solved simultaneously over the entire surface of the concrete element concrete. Rather, a piecewise release by pivoting or tilting of the vertical elements inward is possible.
  • the applied forces to separate the vertical elements of the concrete element are small. The risk of flaking due to the release of the vertical elements is greatly reduced, so that the production of exposed concrete walls is reliably possible.
  • the vertical elements are made of shuttering panels.
  • the weight of the formwork core is reduced, the transport and handling of the formwork core are facilitated.
  • the end elements of the formwork core are formed as end panels; the side elements as side panels.
  • the thickness of the formwork panels is low in relation to their height and length.
  • the ratio of the thickness to the height is ⁇ 1%, so that the thickness of the shuttering panels is significantly less than 2.5 cm with a vertical extension of the vertical element of 2.50 m.
  • Thickness is understood to mean the dimension in the direction of the surface normal of the formwork panel, that is to say the extent perpendicular to the height and length of the panel.
  • the horizontal elements are formed as formwork panels.
  • the formwork panels are reinforced with a supporting structure.
  • the support structure includes panel-like reinforcing elements, which are advantageously and particularly preferably designed as horizontal ribs and vertical ribs.
  • the ribs are each perpendicular to the formwork panel or to the inside. In this way, very rigid and torsionally rigid formwork elements can be produced, but their weight is significantly lower than a comparatively rigid formwork element made of solid material.
  • the pivot levers of the coupling mechanism can be attached to the support structure of the formwork panels of the vertical elements as well as the horizontal elements be.
  • a pivoting of the horizontal elements relative to the vertical elements is significantly simplified due to the relatively thin formwork panels.
  • the construction of the coupling mechanism can thereby be quite simple. Nevertheless, an exact movement and positioning of the individual panels to each other is possible.
  • the vertical elements each have an edge at their upper and lower edge regions, which extends horizontally in the direction of the adjacent horizontal element.
  • the edge of the vertical elements flush with the adjacent horizontal element, when the formwork core is arranged in its concreting, so all elements are connected to each other such that a formwork introduced into the outer formwork core can be used for concreting.
  • At least one corner element is included which is arranged between two adjacent vertical elements and couples the two vertical elements to one another via a coupling element. Between a front element and a side member of the formwork core so a coupling element is arranged such that the end element is coupled to the side member.
  • the corner element is designed such that a movement of the vertical elements inward, in particular a tilting of the vertical elements, is made possible.
  • the corner element is also movable inwards and can be easily solved by the precast concrete to be concreted.
  • the corner element is designed as a corner panel and has stiffening elements on its inner side.
  • the reinforcing elements of the vertical elements in particular the horizontal ribs of the end elements and the side elements, overlap each other at the corner regions. They also overlap the stiffening part of the corner element.
  • the coupling element of the corner element may be formed as a vertically extending guide rod. Corresponding guide recesses are arranged in the stiffening elements and the reinforcing elements such that the guide rod extends through the guide recesses. This way will be through the coupling element, the corner elements guided by the adjacent vertical elements.
  • the guide recess is formed in the horizontally arranged stiffening elements of the corner element as a slot in which the coupling element can be performed.
  • the stiffening element is wedge-shaped axisymmetric to the bisector of the corner element.
  • the slot is then also oriented in the direction of the axis bisector.
  • the guide recess in the horizontal ribs of the vertical elements is preferably a bore which is slightly larger than the guide rod. In this way, in a tilting and movement of the vertical elements inwardly the corner element only then (inwardly) moves when the coupling element abuts the one end of the longitudinal groove and thus entrains the corner element.
  • the corner elements are moved by the vertical elements.
  • at least one horizontal stiffening element of the corner element above a horizontal rib of a vertical element is arranged such that a lifting of the vertical elements causes a lifting of the corner element.
  • the arranged below the stiffening elements of the corner element horizontal ribs support the corner element such that the corner element follows the vertical elements. Their movement, however, is delayed by the coupling mechanism.
  • the corner elements therefore represent path-controlled elements that are controlled by the displacement path of the vertical elements, that is, their movement is controlled by the movement of the vertical elements.
  • the corner elements are caster-oriented, that is, they do not move until after the vertical elements have moved. When so-called spreading, so if the distance of the vertical elements is increased, the corner elements are flow-oriented.
  • the formwork system according to the invention with an outer formwork and a formwork core variable in its outer dimensions has a multiplicity of advantages that result from the operations resulting from this formwork core divide resulting from the resulting with this formwork core concreting processes.
  • the formwork system according to the invention enables the production of monolithic concrete parts, in particular precast concrete components, which have a bottom and one or more side parts. Due to the movement of the formwork core, the precast concrete parts can be produced in the installed position, that is, in the position as they are later used in the assembly of a house consisting of precast concrete parts. This has advantages in terms of the resulting end product as well as the efficiency of the production.
  • the space required is considerably smaller compared to production methods in which the precast concrete component is produced in the reverse installed position.
  • a turning device for the component is not provided.
  • the wage bill is also lower because no additional staff has to be used for the turning process.
  • the biggest advantage in the manufacturing process is that early removal work on the concrete part is possible. Directly after the shuttering process (partial heating / curing) can begin with the finishing work. It is not necessary to wait until the concrete part has completely hardened and the required strength for the turning process of the component is given.
  • the production time of a finished precast concrete part is significantly reduced.
  • the monolithic structure which can be produced with the formwork system according to the invention has the advantage that no assembly stage is necessary in the production sequence, in which the concrete individual parts have to be assembled.
  • the following advantages can be achieved with the formwork system according to the invention: Due to the monolithic nature of the component, fewer steel inserts are necessary for reinforcement. At the same time, a higher stability of the overall system is achieved. Expensive built-in parts for connecting various elements, as they are necessary, for example, in concrete prefabricated, eliminated. The monolithic nature of the concrete part reduces the expense of finishing work, such as piping or cable strands. These can be arranged and placed directly during manufacture, ie before the concrete flows into the formwork system. A later connection is not necessary. Between the individual walls or the walls and the floor no joints and thus no leaks.
  • the concrete element can remain on a so-called circulation pallet, from the concreting phase to delivery.
  • High Abhebelasten be applied only at the end of production on the concrete part. Therefore, a lower reinforcement is necessary.
  • the revolving pallet itself allows earlier stripping, since the release of the formwork sets the required strength for the concrete and not the lifting of the concrete element on the bottom formwork and thus the pressure and tensile forces occurring during lifting.
  • the device according to the invention is explained below by way of example in the production of a room module with side walls and a monolithic floor.

Additional spacer elements between the two floors can be provided; however, they are not essential.
  • the formwork core must have within a mechanism, with which the two opposing horizontal elements can be moved against each other. By the mechanism, the distance can be reduced or spread, so that the vertical elements of the formwork core 3 are spread or shrunk in accordance with the coupling mechanism.

Abstract

Un système de coffrage (1) pour le bétonnage de modules volumiques (21) et d'éléments préfabriqués comprend un coffrage extérieur (2) et un coffrage central (3). Le coffrage extérieur comprend un fond (6), deux parois longitudinales (4) et deux parois frontales (5) qui sont disposées aux extrémités avant des parois longitudinales. Le coffrage central peut être placé à l'intérieur du coffrage extérieur. Il comprend un élément horizontal (10) formant un fond (11) et un élément horizontal formant un élément de recouvrement (12). Deux éléments frontaux (14) et deux éléments latéraux (15) constituent des éléments verticaux (13). Les éléments horizontaux (10) et les éléments verticaux (13) sont agencés de manière à former un espace intérieur creux parallélépipédique dans le coffrage central (3). Les éléments frontaux (14) et les éléments latéraux (15) sont accouplés et reliés mobiles avec, respectivement, le fond (11) et l'élément de recouvrement (12). Un mécanisme d'accouplement (31) est configuré de telle façon qu'un déplacement vertical d'un élément horizontal (10) vers l'extérieur provoque un déplacement des éléments verticaux (13) en direction de l'intérieur. L'intervalle entre les éléments frontaux opposés (14) et les éléments latéraux opposés (15) s'en trouve réduit.
