Definitions

  • the invention relates to a reinforcing mat for reinforced concrete according to the preamble of claim 1 and a method for producing a wall reinforcement using such reinforcing mats.
  • a reinforcing mat of this type has lying in a mat plane, mutually parallel longitudinal bars and these crossing cross bars, which are usually connected at their intersection points by means of welded joints.
  • To reinforce longer wall sections several reinforcing mats are arranged side by side overlapping side by side.
  • additional reinforcing elements such as those in the connection area are used in the connection area DE 3210680 A1 arranged connection baskets arranged. In the wall area, these are applied close to a reinforcement mat to ensure continuous reinforcement.
  • a reinforcing mat according to the preamble of claim 1 is in WO 02/3884 A1 described.
  • An object of the invention is to facilitate the production of reinforcements for concrete structures of this type and at the same time to ensure a reliable connection reinforcement.
  • reinforcing mat 1 consists of mutually parallel longitudinal bars 2, 3 and orthogonal thereto arranged transverse bars 4 made of reinforcing steel, which intersect in a mat plane and are welded together at the intersection points.
  • connection loops From longitudinal bars along a transverse side 5 of the mat successive, U-shaped loops are malleable by the mat is bent back on itself by one or more to the longitudinal bars 2, 3 orthogonal bending edges 6, 7. These loops allow the simple production of a connection reinforcement and they are therefore referred to below as connection loops.
  • the longitudinal bars include four edge bars 2, two of which are arranged along each longitudinal side of the mat 1.
  • the ends of these edge bars 2 are set back on the said transverse side 5 opposite the ends of further longitudinal bars 3 arranged between them by a distance x.
  • edge bars are arranged in the outer half of the limited by the following longitudinal bar, respective mat edge M, so that when limited to these mat edges overlap the edge bars of a first mat behind the edge bars of an adjacently arranged, second mat can be placed (see FIG. 3 ).
  • the ends of the cross bars 4 are bent back in the plane of the mat U-shaped and welded with at least one edge bar 2.
  • the ends of the edge bars lie at a short distance Y, preferably at most 5 centimeters, behind and beyond these intersecting transverse bars; in the longitudinal direction outside the edge bars, no further cross bars are provided.
  • the diameters of the longitudinal and transverse rods are usually between 6 and 12 mm.
  • the edge bars 2 may be slightly thinner than the other longitudinal bars 3, so that the steel density is reduced in the mat edge which is usually laid overlappingly with adjacent mats. For the same reason, the distance between the edge bars 2 and the following longitudinal bar 3 is greater than the distances between the other longitudinal bars.
  • the edge bars 2, the further longitudinal bars 3 and the transverse bars 4 are first cut to their respective, finished longitudinal:
  • the edge bars 2 are shorter by the distance x than the further longitudinal bars 3.
  • the bars according to FIG. 1 arranged to each other and welded together at the intersection points.
  • the ends of the cross bars are bent back in a U-shape in the plane of the mat and welded with an edge bar.
  • FIG. 2 shows the transverse edge of the reinforcement mat according to FIG. 1
  • FIG. 2 shows the transverse edge of the reinforcement mat according to FIG. 1
  • FIG. 1 In side view: Visible are an edge bar 2, one of the other longitudinal bars 3 and the U-shaped bent ends of two transverse bars 4.
  • the figure shows the mat in its state after it has been bent back on itself, so that a bent-back first section 8 of Mat is parallel to a second section 9 of the same mat.
  • a third portion 10 of the mat forms a curved spine connecting the first portion to the second portion.
  • the mat was bent back on itself by bending it twice at right angles about two spaced-apart bending edges 6, 7.
  • first rod portion 11 is hereinafter also referred to as a free leg 11 of the terminal loop.
  • the free leg 11 of a terminal loop should have a length of at least 100 mm. Taking into account the influence of bending radii explained in more detail below and the fact that the terminal loops of overlapping mats are slightly offset from one another, the distance x around which the ends of the edge bars are set back should in any case be at least 150 mm.
  • edge bars 2 are all bending edges 6, 7 outside the edge bars 2, so that the edge bars 2 are not bent at all.
  • the necessary offset x between the ends of the edge bars and the longitudinal bars lying between them depends, among other things, on the dimensions of the connection loops required for a particular building object.
  • a bending edge has a bending radius R.
  • R lies a bending edge 6, 7 behind the ends of the edge bars 2, if they are not bent by the bending of the mat around the bending edge 6, 7.
  • the bending edge 6, 7 thus corresponds to a straight line connecting those points of the longitudinal bars 2, 3, at which a - existing or intended - begins bending.
  • the ends of the provided on one of the longitudinal sides of the mat edge bars 2 are set back relative to the ends of the further longitudinal bars 3, so that the formation of edge loops is prevented on this page.
  • a mat edge with edge loops each comes to rest on a mat edge without edge loops. This is easily possible if all mats are bent back to the same side and the laying of the reinforcement mats is started at the right end of the wall.
  • the ends of the edge bars 2 of both sides are set back relative to the ends of the further longitudinal bars 3.
  • FIG. 3 shows in perspective view two reinforcing mats 1, 1 'according to FIG. 2 , which are arranged side by side overlapping one another in the region of their longitudinal mats edges, so that the edge bars 2 of the first mat 1 lie behind the edge bars 2 'of the second mat 1'.
  • To produce a wall reinforcement several identical reinforcing mats are arranged in this way overlapping next to each other in the region of a concrete wall to be created.
  • FIG. 4 shows in cross section a concrete structure with a bottom 14, a wall 15 and a subsequent ceiling 16.
  • the wall reinforcement includes a number of according FIG. 3 overlapping next to each other arranged reinforcing mats 1, and to these parallel further reinforcing mats 17, which are arranged adjacent to the free legs 11 of the terminal loops.
  • connection loops project up out of the wall area and into the area of the concrete ceiling 16 adjoining the wall.
  • a further reinforcing element 18 is provided, which has a series of mutually parallel prongs 19 and is arranged so that these prongs 19 extend in a running through the terminal loops, cylindrical volume region (eg an additional bent connection element of the type forwa GI or AI of the applicant).
  • the reinforcement mats with molded connection loops are not in stock.
  • the loops are for a specific construction project like that bent so that the loop width W is adapted to the thickness of the wall to be reinforced and the length L of the bent-back reinforcing mat corresponds to the required reinforcement height.
  • the unbent reinforcing mat (as shown in FIG. 1 ) in standard sizes.
  • the further longitudinal bars 3 in a preferred embodiment protrude beyond the ends of the edge bars 2 by a length x of at least 200 mm and particularly preferably at least 400 mm.
  • connection of the bottom plate 14 to the wall 15 is carried out with commercially available floor-wall connection elements, preferably with the wall connection system Forwa 2000 of the Applicant.
