Definitions

  • the invention relates to a method for forming a rigid corner reinforcement for reinforced concrete construction, a reinforcing element and a rigid corner reinforcement, which has been produced using inventive reinforcing elements.
  • connection to the further element is created by means of individual U-shaped bent iron bars which are threaded into the previously bent mat section and aligned with the rod ends in the direction of the course of the surface element to be connected and then verkrödelt with Rödeldraht.
  • the preparation of the mat section by removing individual cross struts or cross strut sections requires a significant amount of time. Equally time-consuming is the preparation and threading of the iron bars.
  • connection to be created by a base plate in the direction of provided in a grid with transverse webs, otherwise hollow cell basement walls is usually to choose this laborious and time-consuming method of connection.
  • a construction for a rigid sole or foundation connection which includes in a special way threaded on an open end of a U-shaped reinforcing element joint tape.
  • the U-shaped reinforcing elements are provided with longitudinal struts, which lie between the bending line and the free ends of the transverse struts.
  • the invention thus addresses the problem of being able to easily produce a rigid corner joint on a construction site in order to save time and effort. Furthermore, suitable reinforcing elements and a rigid corner reinforcement should be specified for these measures.
  • the method according to the invention presupposes that at least two essentially identically shaped, U-shaped reinforcing elements are pushed into each other so as to form the corner reinforcement extending at an angle, preferably at right angles.
  • the reinforcing elements are formed from mats, which have a lot more arranged in a uniform pitch transverse struts as longitudinal struts, wherein the free ends of the transverse struts are bent at an extending beyond the outermost longitudinal struts bending line, preferably at right angles.
  • the construction thus designed is then cast or otherwise surrounded with concrete to form the sole and wall, two walls or the like flat elements.
  • a plurality of reinforcing elements are initially lined up in a first orientation at the end and with preferably present at the reinforcing elements frontal supernatants of the longitudinal struts intermeshed until the respective outermost transverse struts touch each other.
  • the reinforcing elements are preferably connected together, e.g. by knurling the outermost cross struts with Roman wire.
  • second reinforcing elements of the same type are pushed over in the manner described above and then pushed into one another in the same manner on the front side and also preferably connected to one another.
  • the second reinforcing elements can basically be threaded into the first two ways and passed over them.
  • the second reinforcing element can also be inserted with the bottom of its "U” in the space between the opposite ends of the transverse struts of the first reinforcing element, so that on each side of the bottom of the "U” a bent end of each transverse strut of the first reinforcing element lies, one on the free ends of the bent transverse struts of the second reinforcing element facing away from the rear, on the free ends of the transverse struts of the second reinforcing element facing the front.
  • This solution has especially in the reinforcement of a foundation connection the advantage that in the space between the bent ends of the transverse struts of the first, there upright reinforcing element and the bottom of lying threaded second reinforcing element, which projects into the sole, on the outside of comfortable above a joint tape can be introduced. This can then be e.g. at regular intervals, in particular with tie wire, are attached to the outer upright legs or bent ends of the transverse struts of the first reinforcing element.
  • the method described above can be applied both for a rigid reinforcement of a corner joint from wall to wall and also from sole (in particular foundation or ceiling) to the wall.
  • sole in particular foundation or ceiling
  • the method described above can be applied both for a rigid reinforcement of a corner joint from wall to wall and also from sole (in particular foundation or ceiling) to the wall.
  • sole in particular foundation or ceiling
  • a reinforcing element according to the invention for reinforced concrete construction for the reinforcement of connection or transitional areas when connected at an angle connected components or sections is formed of a grid element having longitudinal and transverse struts, which are interconnected at nodes.
  • the free ends of the cross struts are bent along a bending line to a U-shape with free legs and a U-bottom. It is on the one hand essential that the grid element has more transverse than longitudinal struts and further that the cross struts with free ends to a significant excess beyond the outermost, the respective free end nearest longitudinal strut.
  • the free ends of the transverse struts are bent beyond the outermost longitudinal struts, so that the longitudinal struts are all in the bottom of the "U".
  • the cross struts have a predetermined grid spacing from each other.
  • two reinforcing elements thus formed can be inserted into one another in the manner described above and thus toothed together without having to manually detach or remove sections of the transverse or longitudinal struts for this purpose.
  • it can be easily formed by merely bending over the ends, for example by means of a bending device, a fully functional reinforcing element, which is no longer nachzube chandeliern and can be assembled without further aids and at high speed to a corner reinforcement.
  • This results in comparison to the known reinforcement techniques a considerable time savings, which can be several man hours in building a corresponding wall connection. The fact that such a saving is accompanied by a considerable cost saving should be obvious.
  • the grid element according to the invention Due to the fact that the grid element according to the invention has substantially more cross struts than longitudinal struts, it can be bent in U-shape with a comparatively narrow longitudinal strut reinforced section at the bottom of the "U" placed, for example, in the region of the transition to a wall can.
  • the protruding free ends of the cross struts are exposed and can be nested or interlocked with each other to ensure a tensile connection of the reinforcement in the region of the transition.
  • As an abutment for the tensile connection thereby ensure the longitudinal struts, which engage the transversely extending transverse struts of the other of the interlocking elements and thereby provide overcoming tensile forces hold.
  • the number of longitudinal struts is two to six, in particular two to four, is in particular at two longitudinal struts.
  • the number of transverse struts which is chosen to be significantly larger than that of the longitudinal struts, is advantageously between ten and thirty, in particular between twelve and twenty, with particular advantage at sixteen cross struts.
  • a particular freedom in forming a reinforcing element of the grid element according to the invention results when the free ends of the transverse struts by an excess beyond the outermost, the respective free end next longitudinal strut protruding, which is greater than the width measured in the direction of the crossbars provided with longitudinal struts Section of the grid element.
  • the section of the grid element provided with longitudinal struts, which forms the bottom of the "U" in the finished reinforcing element, has, according to experience, turned out to be less wide than the length of the reinforcement, which in the areas to be connected to one another are to be connected to one another or into these sections must be led. This requirement is met by the last-mentioned advantageous embodiment.
  • the excess may in particular be between 50 cm and 100 cm, more preferably between 65 cm and 75 cm, in particular at 70 cm.
  • the transverse struts and the longitudinal struts are perpendicular to each other.
  • the longitudinal struts have a predetermined grid spacing from each other. This can be advantageously between 3 cm and 10 cm, in particular at 6 cm. A grid spacing of 6 cm makes it possible to design a correspondingly narrow base of reinforcing elements produced from the grid element according to the invention by bending.
  • a grid element used for the formation of a reinforcing element according to the invention typically and advantageously has a substantially rectangular basic shape with the longer extension in the direction of the course of the longitudinal struts.
  • An advantageous dimensioning of such a grid element consists in a length of between 1.5 m and 2.5 m and a width of between 1.25 m and 1.75 m.
  • Such dimensioned grid elements are still easy to handle for the formation of reinforcing elements, but still allow the formation of sufficiently large reinforcing elements, which can be readily used in the areas to be connected and interconnected or interlocked.
  • the longitudinal struts advantageously have a projection which projects beyond the outermost transverse struts and is longer than half the distance between adjacent transverse struts.
  • This supernatant is advantageously formed so that two frontally adjacent reinforcing elements can engage with the supernatants, without it being necessary to bend over the supernatants or otherwise deform.
  • the reinforcing element according to the invention can in principle be formed from any suitable material; However, iron or steel struts are preferred here. These iron or steel struts advantageously have a circular cross section with a diameter between 5 mm and 10 mm, in particular 7 mm.
  • the subject of the invention and this protective right is also a rigid corner reinforcement formed from the above-described reinforcing elements. This is formed by telescoping the reinforcing elements as described above.
  • FIG. 1 is schematically shown in a plan view of an embodiment of a suitable for the production of a reinforcing element according to the invention grid element and designated 1 there.
  • the grid element 1 is composed of longitudinal struts 2 and substantially perpendicular to these extending transverse struts 3, which are interconnected at nodes 4.
  • Both the longitudinal struts 2 and the cross struts 3 in the present case consist of iron rods which are welded to the nodes 4.
  • the iron bars of the grid element 1 in this embodiment have a substantially circular cross section with a diameter of 8 mm.
  • the grid element 1 and therefore also the reinforcing elements made therefrom have significantly fewer longitudinal struts 2 than transverse struts 3.
  • the grid element 1 is formed from a total of four longitudinal struts 2 and sixteen cross struts 3. Both the longitudinal struts 2 and the cross struts 3 each have a constant, grid-like distance from each other; the distance a between the cross braces 3 is 12.5 cm in this embodiment; the distance b between the longitudinal struts 2 measures 6 cm.
  • the total length of the grating element 1 according to the invention which is essentially rectangular, is approximately 2.05 m in this exemplary embodiment; the total width is about 1.58 m.
  • FIG. 1 A similar grid element 1 'extending from the grid element 1 FIG. 1 differs only by a smaller number of here only two longitudinal struts 2, otherwise the same structure with the same dimensions, is in FIG. 2 shown.
  • FIG. 4 The side view of such a reinforcing element 5, which has been formed from a grid element 1 ', is in FIG. 4 shown.
  • the free ends of the transverse struts 3 outside of the outermost longitudinal struts either directly adjacent or (as in FIG. 4 shown) are bent in the vicinity thereof, so that all the longitudinal struts 3 in the bottom 6 of the thus formed "U" are.
  • FIG. 3 a situation is shown in which a rigid corner reinforcement is formed according to the invention.
  • the upright reinforcing element 5 is placed as the first reinforcing element in the sole and then threaded the second reinforcing element 5 of the same type on the open ends of the transverse struts 3 of the first reinforcing element and placed horizontally in the sole.
  • basement wall bricks 9 have been here then layered to form the wall.
  • the second reinforcing element 5 has been pushed over the first reinforcing element 5 so that the bottom 6 of its U-shape between the upwardly facing, open at the top free ends of the transverse struts of the first reinforcing element lies.
  • This allows the simple attachment of a joint strip 12 shown here in the space between the back of the base 6 of the second reinforcing element 5 and the opposite free ends of the transverse struts of the first reinforcing element.
  • a wall with Kellerwandsteinen 9 here also connect a cast wall formed in cast-wall, this also on a floor ceiling instead of on a foundation. Then, however, a joint tape is not mandatory.
  • the reinforcing elements 5 are, as can be clearly seen here, moved into one another and toothed, so that they get a tension-stable and rigid connection. Furthermore, it is easy to see how the reinforcing elements 5 with the free ends of the transverse struts 3 each protrude away from the connection point in sufficient length in the adjacent, poured with concrete or pouring element and are anchored there accordingly.
  • the wall 8 When displayed in FIG. 3 the wall 8 has a comparatively small thickness, which is why the reinforcing element 5 is formed with only two longitudinal struts 2.
  • the reinforcing element 5 is formed with only two longitudinal struts 2.
  • four longitudinal struts are formed (eg, a grid element according to FIG. 1 ).
  • a basement brick is in again FIG. 5 in supervision and in FIG. 6 in a sectional view along the section line A - A from FIG. 5 shown and generally designated 9.
  • the basement wall brick 9 is characterized by webs 10 arranged at a regular spacing, between which cavities 11 are left in each case. Typically, the distances between the webs 10 25 cm, the distance between a web 10 and the outer edge of the basement wall brick 9 amounts to 12.5 cm. From such cellar wall stone 9 becomes, as in the FIG. 7 shown, a wall constructed by these basement wall stones 9 offset by half a length placed on each other and the cavities 11 are finally filled with concrete.
  • suitable reinforcing elements 5 made, for example, from a as in FIG. 2 shown grating element 1, also in an excellent manner to connect without the need for further processing of such Kellerwandsteinen 9 formed wall elements tensile strength, since the grid in 12, 5 cm spaced bent ends of the transverse struts project exactly into the cavities 11.
  • a first reinforcing element in a first direction for example, erected on a base for attachment to a sole upright on the base 6, or there are several such reinforcing elements frontally juxtaposed.
  • these are moved with the supernatants z into each other in a plurality of first reinforcing elements and then connected to the outermost transverse struts, in particular verkrödelt.
  • a second reinforcement element is then threaded over the first reinforcement element and pushed so that the base of the first and the base of the second reinforcement element are close together and the free ends of the two reinforcement elements protrude into the respective elements to be reinforced and connected , In the in the FIGS. 8 and 9 As shown, this is done so that the bottom of the second reinforcing element is beyond both upwardly facing, free ends of the crossbars of the first reinforcing element.
  • the second reinforcing element but also as in FIG. 4 shown used with the reason between opposite free ends of the transverse struts of the first reinforcing element.
  • step two If more than one first reinforcing element has been set up in the first step and then these have been pushed together and joined together in step two, several second reinforcing elements are guided over the first reinforcing elements in step three. These too will be with yours Supernatants z pushed one into the other and connected to each other at the adjacent transverse struts 3 adjacent second reinforcing elements, in particular verwrödelt with wire. This shows again FIG. 9 clear.
