Definitions
- Reinforcing steels (prestressing steels) for reinforcement of steel (stressing) concrete have to be sufficient Composite between the steel and the concrete ripping up. This is the power transmission between the steel and the concrete and vice versa so ensured that in use short anchoring or transmission lengths be achieved.
- reinforcing steels in particular cold-formed reinforcing steels, such as e.g. used for welded steel mesh or reinforcing steel in the ring, changed.
- These include e.g. new findings on non-linear design methods in reinforced concrete construction.
- the composite of reinforcing steels was previously considered only in the elastic range of the stress-strain curve of the steel drawn.
- the application of nonlinear design also draws the composite effect in the plastic range of Steel with a (DE-A1-4011486).
- a large part of the reinforcing steel is produced by hot or cold deformation as reinforcing steel in the ring and to Bar or processed into welded steel mesh. To bring the steel into the shape of what it serves as reinforcement can, it must be judged with suitable machines. Ribbed steels always have an out-of-roundness. Further The ribs are removed during the straightening process usually strong. Ignite the ribs on the bar circumference during straightening also a considerable noise. For reinforcing steels, which are made in the ring, is therefore to aim for an improvement of the directionality and a reduction of the noise in judging.
- a reinforcing steel of this type has become known from DE-AS 10 84 464.
- This document describes a reinforcing wire or rod, in particular for prestressed concrete, whose surface having regularly repeating bilateral depressions, wherein the depressions formed elliptical are and take almost half the bar circumference.
- the depressions are in the region of their short axis through separated narrow beads, which lie obliquely to the rod axis. These beads are, similar to diagonal ribs, through Milled grooves formed in the embossing roll, in which the material is displaced during rolling.
- FR-A-1 207 928 discloses a reinforcing steel in which the weldability is improved in the manufacture of welded steel mesh, a surface shape with a smooth surface is sought in a reinforcing steel of round cross-section are three or more rows of shallow depressions of low constant depth in rectangular or parallelogram-like shape rolled.
- a method for producing a ribbed reinforcing steel has become known a round wire rod in a cold drawing process with a cross-sectional reduction of about 20% in a round bar reduced Druchmessers is transferred. Thereafter, the round steel becomes a cross-section in the form of a Triangle rolled with rounded corners and it will be used to form the ribs in the rounded corners Rolled in impressions. The cold working to make the ribs is on the order of 20%
- the DIN 488 is a profiled Bewehsungschracht known.
- the invention is based on the object, the surface shape of a reinforcing steel form so that despite a lower deformation effort, the better ductility parameter Agt and Rm / Re allows a sufficient bond to be guaranteed. Furthermore, a method for producing a reinforcing steel with the specified properties.
- the reinforcing steel according to the invention thus is particularly suitable as a reinforcing element for reinforced concrete components, which are measured using local plastic deformation of the reinforcement.
- the boundary line of the depressions is formed from circular arcs and straight sections, in which there are notch stresses Furthermore, the flanks of the depressions are rounded off in the bottom surfaces If stress on the reinforcing steel is exceeded, notch stress, which is the fatigue strength, is produced impaired, largely avoided.
- the section shown in Fig. 1 in the development of a reinforcing steel has three longitudinal rows 1, 2, 3 of wells 4 on.
- the longitudinal rows are evenly distributed over the rod circumference.
- the depressions of adjacent longitudinal rows are offset in the longitudinal direction of the rod against each other.
- the degree of displacement corresponds to three longitudinal rows about one third of the distance between two adjacent wells of a longitudinal row.
- the rod surface 5 is smooth, i. it corresponds to that of a smooth round rod.
- the boundary line of a depression is in the processing shown in Fig. 1 processing of the reinforcing steel by circular arcs 6 and 7 are formed, which have different radii and with respect to the recess 4 each axially symmetric are arranged.
- the circular arcs 6 with a smaller radius are symmetrical to the symmetry axis 8 and the circular arcs with a larger radius are arranged symmetrically to the symmetry axis 9.
- the symmetry axis 9 of the circular arcs 7 with a larger radius extends in the embodiment of FIG. 1 at 90 ° to the rod axis, i. transverse to the rod axis, the symmetry axis 8 runs parallel to the rod axis.
- the proportion of the total area of the depressions is the total area of the Bar at about 40%.
- Fig. 2 the cross section of a recess in the longitudinal direction of the rod is shown. It can be seen that the recess formed flat, rolled with a constant depth t in the rod surface 5 and by steep flanks 10th is limited. The flanks 10 pass over rounded portions 11 with a small radius into the bottom surface 12.
- the surface design of the reinforcing steel according to the invention is for design methods in which locally plastic deformation of the reinforcement, i. a joint rotation exploited, better than rods with applied to the surface ribs or beads suitable because of the Surface design according to the invention a "soft" composite is made possible.
- Fig. 3 shows a section of a row of ribs of a further embodiment of an inventive Reinforcing steel dar.
- oval wells are arranged obliquely to the rod axis.
- the angle with respect to the rod axis is denoted by ⁇ and should be in the range between 60 ° and 90 °.
- An angle ⁇ 90 ° corresponds to the embodiment according to FIG. 1.
- B is the extent of the depression in the longitudinal direction of the rod, measured in the middle of the transverse extension D, i.e. measured along the center line of the respective longitudinal row of depressions.
- parameter s i. the distance between the boundary lines of adjacent depressions in the longitudinal direction of the rod.
- the inventive method for producing the described rebar differs from the Known method in that first in a first cold forming process, a round wire rod to a Cold rolled steel bar and rolled in a further Kaltverformungsvorgang the shallow depressions.
- the first cold forming operation which can also be divided into two or three cold forming operations, Primarily serves to increase the strength of the reinforcing steel. Depending on the starting material - this can be rolled wires 380 to 420 of the BSTM quality - here a cross-sectional deformation of 10 to 20% will be required can be reduced accordingly when dividing into 2 or 3 Kaltverformungsvorêt. If 3 cold forming operations are provided, they allow the production of an exactly round cross-section of the desired Dimension. For several cold forming operations to make the round bar, the cross section reduction should be used in the first deformation step be greater than in the subsequent steps for the production of the round steel.
- the reinforcing steel or concrete wire according to the invention is intended primarily for the production of welded steel mesh. For this purpose, a minimum yield strength of 500 N / mm 2 is required.
- Rolled wires having a yield strength of from 380 to 420 N / mm 2 and analysis values of. are suitable as starting material for producing the reinforcing steel carbon 0.04 to 0.14% by weight manganese 0.35 to 0.70% by weight silicon 0.20 to 0.30% by weight.
- the process of the invention was in a first deformation process from a smooth round Rolled wire with a diameter of 8.0 mm, a round wire with a diameter of 7.5 mm rolled.
- the cross-section reduction was 11%.
- the result of the wire according to the invention is denoted by I u or I o , the subscripts u and o denoting the bottom or top.
- the comparison wire is denoted by II u or II o .
- the pull-out path s measured on the tension-free bar end, is plotted on the ordinate with the referenced composite stress.
- the reinforcing steel according to the invention is thus characterized by an approximately equal in use composite from, but allows much larger shifts.
- the representation corresponds to that of Fig. 2, i. it is a longitudinal section of the rod through the center of the wells - are the wells at different depths t1 and t2, respectively educated.
- the concrete bracket in the area of the small recess t2 is first sheared off before being sheared off in the area of the large depressions t1. This releases a larger strain value and thus achieve a softer bond.
- a graded "failure mode" is also achieved when the wells 4 have different widths of transverse extent D (see Fig. 3), measured perpendicular to the longitudinal axis of the rod between the parallel to the longitudinal axis Tangents on the boundary line of the respective depression, have.
