Definitions
- the present invention relates to a method for Introduction of shear forces into a concrete body, especially on the face of a concrete slab, at which is the force of an axially extended one Shear bar, e.g. from a shear force mandrel or one Sleeve around the shear force mandrel, is taken up by this with one with the shear bar on at least one close to the concrete surface and a point away from the concrete surface connected shear force bar derived from the shear bar and is transferred to the concrete.
- a shear force mandrel or one Sleeve around the shear force mandrel is taken up by this with one with the shear bar on at least one close to the concrete surface and a point away from the concrete surface connected shear force bar derived from the shear bar and is transferred to the concrete.
- the invention also relates to an element for introduction of shear forces in a concrete body, especially via the Face of a concrete slab, with an axial Shear bar, e.g. a shear force mandrel or a sleeve the shear force mandrel, and with at least one close to the concrete surface and a point away from the concrete surface attached to the shear bar, for Transfer of shear force to the concrete, and it affects also a concrete body with an inventive Shear force element.
- an axial Shear bar e.g. a shear force mandrel or a sleeve the shear force mandrel
- the shear force bracket in Figures 1 and 2 is in one Concrete slab 10 shown cast and has one on the Concrete slab face 11 placed steel slab 13 and two with this welded bracket 15, 15 '.
- the plate 13 has an opening 17 in the center into which a mandrel 19 is introduced.
- the two brackets 15, 15 ' are parallel to each other and to the concrete surface away from the plate 13 and are at a distance from the mandrel axis 21 in a parallel Turned towards the mandrel axis 21.
- the end 23 of the Reinforcing steel forming bracket 15, 15 ' is in a relative large distance to the face 11 of the plate by about 165 to 170 Degrees bent and up to about half way against the Front plate back to the end of the mandrel 19.
- Of the Bracket 15, 15 ' is formed symmetrically to axis 21, see above that shear forces in two opposite directions with the same bracket can be transferred to the concrete slab.
- the four ends 23 of the bracket are with each other and with the mandrel
- the bracket 15 shown in Figures 1 and 2 is a two-edged, backward anchored loop with direct centric contact with the bolt, and deviates from those found to be effective in the study mentioned Orders only insofar as those anchored to the rear Reinforcing iron 15, 15 'by means of a plate 13 in a central position Are in contact with the mandrel and the ends 17 are bent and am Thorn are attached.
- a disadvantage of these prefabricated elements is that Compressive forces occur near the concrete surface on the pressure side. There is therefore a risk of blasting off Concrete parts. Another disadvantage is that the resulting Power flow in the concrete remains unclear. The occurring forces are difficult to calculate because the calculations are not easy Model can be used.
- this is achieved in that a method of the type of bracket mentioned above thus around a part of the concrete body Concrete core is stretched that in the bracket essentially alone Tractive forces arise.
- the bracket is advantageous in one Arch stretched around the concrete core. This will kick the Compressive forces in the concrete inside the arch section.
- the bow section is arranged on the train side is included shear force rod arranged in approximately half the plate thickness certainly a larger part of the plate thickness on the Pressure side than on the tension side of the bracket.
- the preferably flat sheet is advantageous stretched symmetrically around the concrete core.
- the symmetry allows a simpler calculation of the forces that occur because the force components directed transversely to the axis of symmetry cancel each other out.
- the sum of the force vectors thus forms a vector on the axis of symmetry.
- the concrete load is especially in the case of a flat arch section, since only Compressive forces occur in the concrete, similar to a vault.
- a flat arch section has the advantage of smaller ones local pressure forces and a three-dimensional force game, which increases the local resilience of the concrete.
- a first one with the shear force rod is advantageous connected bracket or bracket section around one near the concrete surface and a second with the Shearbar connected bracket or bracket section with opposite direction of action by one concrete core distant from the concrete surface. This can do that due to the eccentric load on the shear force rod occurring moment are caught.
- the bracket is a loop element, the sections attached to the shear bar at a distance from Shear bar are connected by an arc section.
- the bow is ideal for pulling forces in the Arch element in compressive forces in the inside of the arch Transfer core.
- the loop element is advantageous so flexible under the forces occurring under load, that it essentially absorbs tensile forces alone. This can e.g. a chain, a wire rope or wire mesh, a sheet, a glass or carbon fiber structure or the like. A firm connection with high friction between the Loop element and the concrete is not desirable since the Loop only due to its shape and load Pressure forces on the circulated concrete core.
- the loop element preferably has one symmetrical arch section, e.g. an arch section with a circular, elliptical or parabolic arc.
- the Forces in such a symmetrical or geometric defined arch section and also by this Forces section in the concrete are simple Models can be calculated.
- the loop element advantageously has in the region of the Arch section on a curved surface element, so that the Local forces are as small as possible.
- the loop element is preferably made of a band shaped, which has a large width relative to the thickness having.
- a band can be practical in the band direction do not absorb compressive forces because it is too thin.
- Due to the flexibility of the Band can be assumed for the calculation that the band is stretched around a virtual role, so no one-sided pull on the belt is possible. Hence the Pressure distribution in the concrete core inside the loop very much simple.
- the arc section is essentially advantageous around an axis is parallel to the concrete surface, and is at least one of those connected to the shear bar Sections of the loop element bent or so twisted that the bent or twisted part along a line or surface parallel to the shear force axis Shear bar touches. Due to the parallelism of the arc axis the force distribution is parallel to the concrete surface to the concrete face. As a result, the pressure forces do not show against the concrete surface, which such compressive forces practically cannot record. Through the lines or surface contact between the shear bar and Loop element is a very good attachment option given.
- Holes or eyelets are arranged to attach the shear force element fasten a concrete formwork with nails through the holes can.
- the section of the Bands advantageous at one point away from the concrete surface Section at the appropriate point and are at this protruding point holes are provided in the tape to attach the tape formwork through the holes.
- the loop element is advantageously symmetrical formed with respect to the shear force axis, so that Shear forces in two opposite directions can be introduced into the concrete. This will put the item on construction site with greater certainty transferred.
- the shear force rod advantageously has one in the concrete area that is about twice as long is like the distance between the two attachment points of the loop element on the shear bar, possibly the two fastening points closer to the concrete surface, so practical for the loop element at both fastening points the same burden can be assumed.
- the parallel to the shear force axis is advantageous lying diameter of the arc section smaller than that Distance of the most distant point of the arch section from Shear bar. This gives you the greatest pressure on the tension side of the shear force rod and therefore with relative large distance to the concrete surface on the pressure side.
- a concrete body with an inventive Shear force element is advantageous in the area around the Shear force elements (40) reinforced by a fiber reinforcement. Due to the fiber reinforcement, both the tension and the Compressive strength of the concrete can be increased.
- the concrete body is advantageously a prefabricated one Element, and reinforcements protrude from the element with which the element with a concrete body cast on site can connect.
- a Prefabricated element can be treated separately Edge area of a concrete body when pouring the concrete body be avoided. This means that no one is needed on the construction site Monitoring the fiber addition in the concrete with which the Shear force elements are cast.
- the prefabrication allows a rational production of the edge elements under guaranteed conditions for their quality.

- the Shear force elements 40d and 40d ' for example, in two Cast concrete slabs 10 and 10 '.
- the leg sections 45d are the Loop elements 43d directly on both sides of the joint between the two plates 10, 10 'or respectively on the End face 11,11 'of the plate arranged.
- the shear force mandrel 41d bridges the gap and is in the shear sleeve 42d.
- the loop elements 43d are symmetrical in the example trained, i.e. they can be in two to each other opposite directions absorb shear forces as they one on both sides of the mandrel 41d or the sleeve 42d Have arc section 47d or 48d. Is from the plate 10 a shear force down onto the supported plate 10 ' transferred, the arc sections 47d are used to make the To transmit force, for forces in the opposite direction correspondingly the arc sections 48d.
- the symmetrical Loops 43d are bent from a band so that the mandrel 41d or the sleeve 42d through the two band ends 61 and 63 is guided and these are in contact with each other and at most are additionally connected by welding or gluing. Pressure forces can be in the loop element 43d because of its band-like design practically no occur. A Blowing off concrete parts near the pressure side Concrete surfaces are therefore not to be feared.
- FIG. 8 shows the shear force element 40d according to FIG. 7 in connection with reinforcement of the slab edge a concrete slab corner.
- the section close to the concrete surface 45d of the loop element 43d is in the end face 11 or arranged at a small distance behind the end face 11, the shear force mandrel 41d perpendicular through the end face 11 passes through.
- the plate edge is with U-shaped brackets 64 armored, their arms 66 near the top and bottom Plate surface aligned perpendicular to the face 11 are.
- the connection 68 of the two arms 66 or legs runs parallel to the direction of the face 11 force to be introduced 53.
- the panel edge with fiber reinforcement is preferred, i.e. by adding glass or carbon fibers to the concrete mass, reinforced. Plate pieces reinforced in this way, as in the figure 19 shown, advantageously prefabricated and by a suitable reinforcement connected to the concrete slab.
- Figures 9 and 10 show symmetrical loop element 43e and 43f, which are formed by a flattened piece of pipe are.
- the shear force element 40e in Figure 9 is in the Shear force element 40f insertable in Figure 10.
- the thorn 41e works with the sleeve 42f.
- the Loop elements 43e, f have holes 51 around them Nail shear force elements to a formwork.
- the Arc sections 47e, 48e, 47f, 48f are holes 52 incorporated so that the interior inside the loop 43e, f is completely filled with concrete during concreting and no air bubbles have to be transmitted to the pressure forces Included inside the arc sections 47e, f, 48e, f become.
- the holes 51 for attaching the element to the Formwork are advantageous on a laterally protruding Tab 65 formed on leg portion 45f to make it good are accessible.
- FIG 11 is a symmetrical shear force element 40g shown with two symmetrical loop elements 43g and 43g 'in a row.
- the sleeve 42g is through all Leg sections 45g, 49g, 49g ', 55g passed through.
- Of the Leg section 45g is reinforced by a plate 67.
- This plate 67 lies in the end face 11 of a concrete plate 10.
- Through the plate 67 are also through the arch of the Arch sections 47g, 48g conditionally ending to zero Concrete burrs 69 between the concrete surface 11 and the Protected arc section 47g, 48g. Take over these ridges 69 however not a static function, they are also likely to break out or do not have to be concreted at all.
- loop 43g ' Since in Loop element 43g 'remote from the end face the smaller forces act as a loop element 43g close to the end face, the loop 43g 'is made from a thinner sheet metal strip.
- the concreted-in end of the sleeve 42g has a cover 71 closed so that no concrete can penetrate.
- a symmetrical double loop can, as in FIG. 12 shown to be made from a single band.
- the adjoining leg section 49h 'runs behind the Band end 61 passes through, again in an arc section 58h over in the rear leg section 55h and from there in another bow 57h back in the middle with the Leg sections 49h, 49h '.
- the sleeve 42h therefore passes five times the ribbon guided in a figure of eight.
- FIGS. 13 and 14 show a shear force element 40i in a side view or a section along the line X-X shown in Figure 13.
- Disc-shaped on both sides Shear force mandrel 41i is a band bent into an eight arranged.
- the band ends 61,63 are at one in the Welded plate 67 to be placed on the concrete surface. From one end of the tape parallel to the plate 67 going upwards 61 the ribbon goes back in an arc 47i to the mandrel 41i. It is twisted so that when passing the mandrel 41i the surface 73 of the band parallel to the side surface 75 of the disc-shaped mandrel 41i runs.
- the tape continues to twist into the opposite Direction, runs in an arc 57i back to the mandrel 41 'um in an analog S-loop over the bow 58i and 48i to get back to plate 67.
- the vectors of those occurring in the concrete Compression forces are light in arc sections 47i and 48 to the rear, slightly curved in the arch sections 57i, 58i directed in front.
- the band is on the one passing through the thorn Place with this, e.g. thanks to a weld. So that the tape describes a favorable curve, it can be one that is curved or even not level Ribbon bent.
- Figure 15 shows a perspective sketch of a Shear force element 40k with a plate 67, one on it Loop element 43k and a round mandrel 41k. It is one end 61 of the loop member 43k on the plate 67 attached. The other end 63 is divided and the two flanks 77 of the left and right of the mandrel Leg section 49k are bent obliquely so that they rest on the mandrel on a line parallel to the mandrel axis. The two parts are guided around the mandrel 41k. The Flanks 77 are connected to one another along the mandrel.
- the band-shaped loop element covers with its surface Thorn, which causes greater forces from the thorn to the Loop element can be transferred as if the mandrel just passed through an opening in the surface is.
- the loop elements 43m and 43n in the shear force elements 40m and 40n with the thorns 41m, n connected Figures 16 and 17.
- a closed one Band loop or ring loop 43m, n is around the rod-shaped Thorn 41m, n looped and forms two side by side lying, essentially rectified arc sections 47m or 47n.
- the ring loop 43m, n can be against each other ( Figure 16) or apart ( Figure 17).
- Such Fixings of shear force elements 40m, n are also for Loop elements 43m, n made of non-metallic raw materials suitable. So the tape can be made of a glass or Carbon fibers exist, which are advantageously in a resin are embedded.
- the shear force element 40p shown in FIG. 18 has a mandrel 41p, around which a ring loop 43p so is struck that the loop 43p near the concrete surface performed flat against the mandrel 41p under the mandrel 41p is.
- the band of the loop element is on both sides of the mandrel twisted by 90 degrees and in an arc 47p, like a roll with an axis aligned parallel to the face of the plate placed, and returned against the mandrel axis.
- the Band 43p is then around on each side of mandrel 41p two rods directed parallel to the face of the panel looped.
- the tape 43p runs under a bar 81 through which rod 81 is attached to the mandrel under the mandrel is.
- the band 43p is in an S line back up and struck around a rod 83 which abuts over the mandrel 41p this is attached.
- the ring band 43p then runs in parallel down on both sides of the mandrel 41p and back, next to over the mandrel 41p to two below the mandrel 41p to form corresponding arc sections 57p and finally twisted by 90 degrees on the top of the mandrel 41p lying flat around the mandrel.
- the driving around of two rods 81.83 with the tape causes the Tractive forces in the front loop part 47p not on the rear loop part 57p are transmitted.
- the thorn would be, as a model, parallel downwards movable, i.e. on the one hand, larger ones would arise Tensile forces in the rear arch area and on the other hand larger Pressure forces from the mandrel to the concrete.
- FIG. 19 shows a prefabricated edge element 10 ′′ with a number of shear force elements, of which only the from the end face 11 protruding parts of the Shear force mandrels 41 are visible.
