Definitions

  • the invention relates to a formwork casing for the production of concrete slabs, consisting of a double fabric, the lower fabric and the upper fabric of which are woven together at the edges of the casing and in which the upper fabric runs parallel to the edges in the warp and weft direction, forming several lines
  • rectangular or square chambers are connected to the lower fabric, each chamber being assigned spacers that limit the bulging of the shell walls and the chambers are connected to at least one filling opening for the concrete via connecting openings, and wherein reinforcements made of concrete that are continuous in the interior of the formwork shell are in the interior Material are arranged.
  • Formwork casings of this type are known from CH-A464807 and FR-A-2 347 492. With the help of these casing casings, concrete slabs can be produced which are composed of several rectangular or square single slabs largely separated from one another by joints or channels, but which are still are connected to each other via concrete walkways. The connecting concrete webs are created when the formwork envelope is filled in the openings of the connecting lines separating the chambers.
  • the concrete slabs made with the formwork cover are used to protect embankments and soles, canals, rivers, and also to protect dikes, planks, jetties on the coast, lakesides and the like.
  • the concrete slab on the concrete webs breaks along the rectilinear joints or gutters formed by the connecting lines of the formwork cover, and the fragments in the form of rectangular or square slabs can follow the movement of the floor.
  • the formwork covering is not rotten or weakened or destroyed by UV radiation, aging or other reasons, the fragments of the concrete slab remain in a closed bond.
  • Formwork casings of the type in question are made of a material that after a few years is so weakened that they can no longer hold the fragments of the concrete slab together. The fragments can then migrate so that wide joints are created in the revetment and the bank or canal embankment is no longer adequately protected.
  • the object of the invention is to create a formwork envelope with the aid of which a concrete slab is created, the plate-like fragments of which remain connected to one another even after the formwork envelope has been destroyed.
  • the reinforcing threads for the concrete slabs are preferably made of nylon or polyamide yarns and are introduced into the double fabric in the form of cords, strands, ribbons or ropes.
  • Reinforcement threads in the form of cords can have a diameter of 0.8 to 1.2 mm, while reinforcement threads in the form of ribbons have a cross section of, for example, 5 mm. Can have 0.6 mm.
  • the reinforcing threads can also be steel cords, which are also used, for example, to reinforce vehicle tires.
  • the reinforcing threads connected or woven at least to the lower fabric do not hinder the breaking of the concrete slabs at the joints or channels due to their elasticity, but they prevent - because their elasticity is limited - that the broken parts move apart.
  • the reinforcing threads are introduced into the double fabric of the formwork cover so that when the formwork cover is filled with concrete they anchor themselves in the concrete and at least do not lie at the top in the area of the predetermined breaking lines transverse to the embankment. This prevents the reinforcing threads from being weakened or destroyed by UV radiation or mechanical stress.
  • the reinforcing threads in the region of each chamber are advantageously connected once to the upper fabric. When the formwork casing is filled with concrete, the upper fabric lifts off the lower fabric, so that the reinforcement threads run through the formwork casing in a zigzag fashion and are thereby reliably anchored in the concrete.
  • the chambers of the formwork casing are each separated from one another by a double row of punctiform connections.
  • the punctiform connections can be formed at least partially by punctiform interweaving of the upper fabric with the lower fabric. However, they can also be formed by connecting webs whose length is less than half the length of the spacers. If the spacers have a length of, for example, 25 cm, then the connecting webs can have a length of 6 to 10 cm.
  • the connection webs can be designed according to the spacers.
  • the double row of punctiform connections creates intermediate areas between the chambers of the formwork envelope, which are also filled with concrete.
  • the thinner concrete layer thus formed in these intermediate areas serves as a predetermined breaking point.
  • the formwork casings are placed on an embankment in such a way that the warp threads run in the direction of the slope of the embankment and the weft threads run transversely to the embankment. For this reason, the reinforcement threads run in the warp direction, since there is a particularly great risk that the broken parts of the concrete slab will slide off the slope during washing.
  • spacers and, if appropriate, the connecting webs from a material which is resistant in concrete. These spacers connect the lower fabric, which is protected against UV radiation and other damage, to the concrete slab or its fragments.
  • the spacers can be formed in a known manner by ribbons running in the warp direction and alternately integrated in the lower and upper fabrics.
  • filter surfaces are arranged in a further embodiment of the invention, which are formed by floating the weft and warp threads and at the edges of which the upper fabric is woven with the lower fabric. These filter surfaces cause water located under the concrete slab to escape upwards, but sand and the like are retained by the filter surface. The filter surfaces are so large that even with a high water load under the concrete slab no greater water pressure can build up.
  • the formwork shell shown in FIGS. 1 and 2 consists of a double fabric, the lower fabric 1 and upper fabric 2 are woven together at the edges 3 and 4. Furthermore, the upper fabric 2 and the lower fabric 1 are connected or woven together along connecting lines 5 and 6 running parallel to the edges 3 and 4 in the warp and weft directions.
  • the connections along the connecting lines 5 and 6 form a plurality of chambers 7 which are square in plan view.
  • a plurality of spacers 8 which limit the bulging of the casing walls are arranged in each chamber.
  • the chambers 7 are connected to one another via connecting openings 10 and to a filling opening 9 for the concrete. 1 is, for example, 10 m long in the warp direction and 5 m wide in the weft direction.
  • the connecting lines 5 and 6 are arranged at intervals of approximately 1 m, so that the individual plates which form in the chambers 7 are approximately 1 m 2 in size.
  • the spacers 8 have a length of, for example, 25 cm.
  • the peeling casing is fastened to an embankment in such a way that the connecting lines 5 running in the weft direction run transversely to the embankment. So that the fragments do not migrate when the concrete slab breaks along the connecting lines 5 running in the weft direction, reinforcing threads 11 are introduced into the formwork cover and are anchored at least in the lower fabric 1.
  • the reinforcement threads are in the form of woven or knitted ribbons, cords, soaps and consist in particular of nylon or polyamide yarns. As shown in FIG. 2, the reinforcement threads 11 are introduced into the formwork cover in such a way that when the formwork cover is filled with concrete, the reinforcement threads anchor themselves in the concrete.
  • the reinforcing threads 11 are connected to the upper fabric 2 at least once in the region of each chamber 7.
  • the reinforcing threads 11 are connected to the lower fabric 1 on both sides of the connecting lines 5 running in the weft direction. This ensures that the reinforcing threads in the finished concrete slab are protected against UV radiation and mechanical damage and retain their high resilience.
  • the chambers 7 are each separated from one another by a double row of punctiform connections 12 which run along the connecting lines 5, 5 'and 6, 6'.
  • the punctiform connections can be formed by punctiform interweaving of the upper fabric 2 with the lower fabric 1. However, they can also be formed by woven-in or inserted connecting webs 12, the length of which is less than half the length of the spacers 8. If the spacers 8 are approximately 20 to 25 cm long, then the connecting webs 12 can be 4 to 10 cm long.
  • the spacers 8 appear as small circles, while the connecting webs 12 appear as dots. Both the spacers 8 and the connecting webs 12 can be formed by plastic tapes running in the warp direction, which are alternately woven into the lower fabric 1 and the upper fabric 2.
  • the shorter connecting webs 12 between the chambers 7 create intermediate regions 13 which serve as predetermined breaking points.
  • reinforcing threads 11 run in the chambers 7 in the warp direction, which, as shown in FIG. 5, are partly connected to the lower fabric 1 and partly to the upper fabric 2.
  • the reinforcing threads 11 are connected to the lower fabric 1 both on the connecting lines 5 and 5 ′ and on the rows of spacers 8 lying next to them.
  • the connections to the lower fabric are designated 14.
  • the reinforcing threads 11 are tied to the upper fabric 2 approximately in the middle of the chamber 7.
  • the connections to the upper fabric are denoted by 15. This arrangement of the reinforcement threads 11 in the double fabric ensures that the reinforcement threads 11 are stretched when filling the formwork cover, although the.
  • the formwork cover "shrinks" when it is filled.
  • filter surfaces 16 are arranged, which are formed by floating the weft and warp threads of the double fabric.
  • the filter surfaces 16 are square and their side length is approximately half the side length of the chambers 7.
  • the side length of the filter surfaces 16 is also three times the distance between the connecting lines 5, 5 'and 6, 6' from one another. The filter surfaces ensure that water can pass through the revetment from below, but at the same time sand is retained.
  • the woven reinforcing threads running in the warp direction do not hinder the breaking of the plates in the intermediate regions 16 because of their extensibility, but they prevent the plate parts from straying apart or wandering. These reinforcing threads also prevent the individual panels from sliding together.
  • the reinforcement threads 11 are connected several times to the lower fabric 1 at the connection points 14 and once to the upper fabric 2 at the connection 15. Since the casing walls bulge between the spacers 8 and the connecting webs 12 when the formwork casing is filled with concrete , The reinforcing threads 11 are anchored in the concrete, provided that it is ensured that the reinforcing threads are kept taut by connection to the upper fabric 2.
  • the reinforcement threads 19 that can be seen in FIG. 1 and run in the weft direction can be arranged in their course corresponding to the reinforcement threads 11 and connected to the lower and upper fabrics. Because of the lower load, the reinforcing threads 19 running in the weft direction can be weaker or less densely arranged.
  • spacers 8 can be made of a material resistant in concrete, so that after breaking the concrete slab the bridges on the one hand by the reinforcing threads 11 and on the other hand the protected and via spacers 8 and the connecting webs 12 connected to the concrete fragments lower fabric are held in their correct position.
