Definitions

  • the invention relates to a reinforcement for reinforced concrete structures, which the parts to be installed or recesses interrupting the reinforcement, such as e.g. Joint tapes or connection recesses on precast structures, surrounded and forms a replacement of the interrupted reinforcement.
  • the invention has for its object to provide a reinforcement of the type mentioned, which requires fewer parts and shorter installation times, can be produced mechanically in the factory as a batch and can be easily installed at the construction site.
  • the reinforcement designed according to the invention in that it consists of egg Nem pair of reinforcement elements, each of which has at least one Z-shaped curved bracket, and that these two elements are arranged in a mirror-inverted manner, so that between the central parts of the bracket the part to be installed or the recess and the leg of the recess associated with the leg of the Form a closed cage reinforcement in the area of the crack zones.
  • two mutually identical reinforcement elements with brackets in Z-Fozm are thus provided, which are opposite, ie. H. in mirror image, with mutually parallel central parts, arranged in the desired distance adapted to the recess, overlapping their legs lying in the replacement zone.
  • This allows you to adapt to varying wall thicknesses and widths of the built-in part, such as a joint tape, or the recess to be provided in wide areas, u. each with a pair of elements designed in this way.
  • a special embodiment of the invention is that several brackets are connected to one element by holding rods, preferably by welding. Such elements can be easily prefabricated in the factory and easily stacked.
  • a previous joint tape guard consists of two U-brackets 1 which are arranged next to one another while leaving a distance, and a further bracket 2 which extends between the outer legs of the bracket 1.
  • the encirclement consisting of these three brackets 1, 2 is fastened to the vertical support rods 3 in a conventional manner.
  • the vertical joint tape 4 is arranged between the inner legs of the bracket 1, normal to the plane of exchange, and is connected by means of the clamps 5, which comprise both ends of the joint tape 4, to the bars 3 with wires 6 and thereby tensioned.
  • the bracket 2 prevents cracking in the areas of zones A and B after the concrete has been poured.
  • FIGS. 3 and 4 A corresponding procedure has been followed in the manufacture of a barrier for the horizontal joint tape of a foundation plate with a rising wall, as can be seen from FIGS. 3 and 4.
  • the rod 7 has to perform the function of the bracket 2 in Fig. 2; it bridges, held on longitudinal rods 8, the ends of the transverse rods 10 and 11 which are precisely bent with respect to their spacing and which are connected by the longitudinal rods 12, 13, and 14.
  • the joint tape 16 lying at the base of the wall is arranged normal to the replacement plane, and the crack zones A, B are reinforced by this type of replacement.
  • the reinforcement element E1 and E2 consists of a series of Z-brackets 17 and 19, each in a curved Z-shape, with an upper leg 17b, 19b with the bracket middle parts 17a, 19a Length X2 and at the end a downward curve 17c, 19c with of length Y2 and a lower leg 17d, 19d and at the end an upward bend 17e, 19e with length Y1 are provided.
  • This row of Z brackets 17, 19, which have the same distance X8, is connected to one another by two holding rods 18, 20 (FIG. 9).
  • the outer holding rod 18, 20 is arranged on the bend 17c, 19c of the upper leg 17b, 19b of the bracket 17, 19, approximately in the middle thereof, and the inner holding rod 18, 20 is on the middle part 17a, 19a of the bracket 17, 19 arranged around its upper quarter point.
  • the rods 18, 20 are with the brackets 17, 19, z. B. connected by welding.
  • the holding rods 18, 20 do not hinder the pushing together of the elements E1, E2 described below.
  • the holding rods 18, 20 must therefore lie above the ends of the legs 17e, 19e.
  • the middle parts 17a, 19a of the brackets 17, 19 lie at a distance X1 from one another and the upper and lower bends 17c, 17e and 19c, 19e are exactly one above the other.
  • the length X2 of the upper leg 17b, 19b corresponds to the distance between the middle part 17a of one bracket 17 and the bends 19e of the other bracket 19, and vice versa. 7 for a minimum wall thickness of X1 + 2.
  • X2 X3 suitable.
  • the element E3 according to FIGS. 10 to 12 differs from those according to FIG. 5 in that the upper leg 21b of the Z-bracket 21 with the length X9 is not bent over, but rather protrudes from the bracket middle part 21a.
  • the lower leg 21c with the bend 21d has the length X10 (FIG. 10).
  • the brackets 21 are connected to one another by holding rods 22 at a distance X11 (FIG. 11). This results in z. B. a barrier according to FIG. 12, in which the middle parts 21a of the bracket 21 are at a distance X12 and the crack zones 24, 25 are covered again.
  • Figs. 13 to 15 illustrate the assembly of the reinforcement elements E1 according to the invention, E2 in an application according to Fig. 2.
  • 13 F ig. In consisting of transverse rods 25 and longitudinal rods existing 26 supporting reinforcement of a wall first of the one element E1, which is similar 6, but has a bend 19e with the length Y3 on the lower leg 19d of the bracket 19 (FIG. 14), and then the other element E2 is inserted (FIG. 15) and connected to the bars 25, 26, e.g. B. by binding with wire. Anticipate the supporting rods have been inserted 28 in order to be able to connect to the assembly of the elements E1, E2 at the corners (FIG. 15).
  • the rods 27 must be inserted and fixed in the direction of the arrow P f.4. Thereupon, the F is ugenband 29 in the remainder of the recess, used on the wires 30 held in clamps 31 and tensioned.
  • the crack zones 32 are so well secured by this cage reinforcement.
  • FIG. 16 to 19 accordingly illustrate the installation of a reinforcement made of elements E4 in a foundation plate in the application according to FIG. 4.
  • the foundation plate reinforcement (FIG. 16, 17) formed from the transverse bars 33, 35 and the longitudinal bars 34
  • an element first becomes E4, similar to FIG. 10, inserted with brackets 21 and holding rods 22 and connected to the foundation reinforcement (FIG. 18), and then the second element E4 is introduced (FIG. 19).
  • the upper rods 36 must be inserted in advance, and finally the joint tape 39 is tensioned with the wires 37, which are components of the clamps 38.
  • both legs of the Z-bracket adjoining the central part can also be straight.
  • the arrangement of the holding rods 18, 20 can also take place at a location other than that shown if they only allow the pair of elements to be fitted into one another.
