Definitions
- the invention relates to a tension anchor for band-shaped tension members in construction, in particular fiber-reinforced plastic lamellae, with at least one anchor body which is non-positively connected to the tension member by adhesive and / or friction and can be supported on a fixed abutment.
- plastic slats are preferably used for this purpose, in particular plastics reinforced with carbon fibers (CFRP), plastics reinforced with Ara id ( ⁇ FK) and plastics reinforced with glass (GFK).
- CFRP carbon fibers
- ⁇ FK Ara id
- GFK plastics reinforced with glass
- the activatable adhesive length which takes up the load introduced by the tension member due to shear stress, is relatively short, it occurs at the transition from the free span length to the anchoring zone to a shear stress peak that exceeds the locally permitted shear stress in the adhesive joint and reaches the breaking stress.
- the decisive breaking criterion in the case of adhesive bonding is that the cohesion of the adhesive is exceeded and / or the plastic matrix of the band-shaped tension member breaks. The resulting breaking shear stress front travels along the adhesive joint until the adhesive connection fails completely.
- the object of the invention is therefore to design a tension anchor of the type mentioned at the outset in such a way that the occurrence of a shear stress peak which locally exceeds the breaking stress in the adhesive joint or in the friction region is avoided.
- Adhesive and / or friction connected clamping blocks the last clamping block towards the end of the tension member It is possible to support the stationary abutment in such a way that the clamping blocks are connected to one another by expansion sections of different spring stiffness and that the spring stiffness of the expansion sections increases towards the end of the tension member.
- an anchor body is arranged on both sides of a band-shaped tension member or a layer of two band-shaped tension members, the respective overlying clamping blocks of which are connected to one another by clamping elements.
- the clamping elements are preferably tension screws arranged on both sides next to the tension member.
- expansion sections arranged between the individual clamping blocks are designed in a structurally particularly simple and easy to manufacture manner as connecting webs with different web cross-sections.
- the different web cross-section which types described below can be achieved, leads to different spring stiffness. In this way, the requirement can be realized in a very simple manner to increasingly carry out the spring stiffness of the expansion sections from the point at which the tension member enters to the end thereof.
- FIG. 1 shows in a longitudinal section a highly schematic representation of a tension anchor for a band-shaped tension member, spring symbols being used for the expansion sections of different spring stiffness
- FIG. 2 is a plan view of the schematically illustrated tension anchor according to FIG. 1,
- FIG. 3 is a plan view of an embodiment of a tension anchor for a band-shaped tension member
- FIG. 4 shows a side view of the tension anchor according to FIG. 3, the support on a stationary abutment being omitted for the sake of clarity,
- FIG. 5 shows a spatial representation of the tension anchor according to FIG. 4
- 6 is a plan view of a clamping body according to a first embodiment
- Fig. 7 is a section along the line VII-VII in Fig. 6 and
- a tension anchor for band-shaped tension members 1 is explained schematically, for example of slats made of carbon fiber reinforced plastic (CFRP slats).
- CFRP slats carbon fiber reinforced plastic
- These band-shaped tension members 1 are used in construction for upgrading or renovation, of structures made of prestressed concrete or reinforced concrete.
- the band-shaped tension members are glued to the concrete surface, for example, or remain unattached to the concrete surface.
- the tension anchors described are used to apply a
- an anchor body 2 is connected to the tension member 1 by gluing and clamping. Instead, the. Bonding can also be done by friction.
- the adhesive bond is described below as one of the possible exemplary embodiments.
- the anchor body 2 has a plurality of clamping blocks 3 which are arranged at a distance from one another in the longitudinal direction of the tension member 1.
- Each of the clamps 3 is connected to the tension member 1 by means of an adhesive layer 4.
- clamping screws 5 which are only indicated schematically in FIG. 1, everyone is Terminal block connected to a clamping counterpart 6.
- These clamping counterparts 6 can in turn (not shown) be parts of a second clamping body 2 on the underside of the tension member 1.
- the last clamping block 3 towards the end of the tension member, in the exemplary embodiment shown the leftmost clamping block 3, is on a stationary, i.e. supported on the supporting structure abutment 7, for example via a hydraulic tensioning device 8.
- expansion sections 9 are formed, which are symbolized in the illustration of FIGS. 1 and 2 as groups of tension springs.
- the different thickness of the tension springs means that the expansion sections 9 are designed with different spring stiffness, the spring stiffness increasing from the transition point 10 from the free span length of the tension member 1 into the anchoring zone towards the end of the tension member (left in FIGS. 1 and 2) ,
- the spring stiffnesses of the expansion sections 9 are selected and graded such that the introduction of force into each clamping block 3, which takes place via shear stresses in the adhesive layer 4, prevents the occurrence of shear stress peaks that exceed the maximum admissible shear stress in the adhesive and would lead to a break in cohesion. Deviating from the designs shown in the drawing, gluing can also take place in the region of the expansion sections 9.
- the different spring stiffness of the expansion sections 9 can be achieved constructively in different ways; preferred examples of this are shown in the following figures.
- a clamping anchor for tension members for example carbon fiber reinforced plastic slat is disposed on both sides of a layer of two strip-shaped tension members 1 in each case an anchor body 2, which respectively superposed Klemmbl ⁇ cke 3 respectively by side 'in addition to the tension members 1 arranged lag screws 5 are connected and clamped.
- the tension screws 7 each act on the respective clamping block 3 via a transverse yoke 11 via two adjacent support points 11a, 11b. Instead, a single, central support point can also be selected.
- Several, individually functioning, identical tension anchors can be combined as modules to form a larger tendon by stacking one on top of the other, using longer, common screws 7.
- the last clamping block 3 towards the end of the tension member 1 is connected to a head plate 2a of the anchor body 2.
- This head plate 2a is supported on the stationary abutment 7 via lateral hydraulic clamping cylinders 8.
- the expansion sections 9 between the clamping blocks 3 are formed by ' connecting webs 13 which are of the same width but different thicknesses.
- the thickness of the Connecting webs 13 increases from the transition point 10 to the head plate 2a and thus to the end of the tension member 1.
- FIG. 6 shows a top view in a simplified representation of the basic structure of the anchor body 2, as it is used in the embodiment of FIGS. 3-5. 8-15 show further exemplary embodiments in the same manner of representation.
- the connecting webs forming the expansion sections 9 between the clamping blocks 3 each consist of a plurality of web sections 14 which are separated from one another by recesses, in the example according to FIGS. 8 and 9 bores 15 running perpendicular to the band-shaped tension member 1 are.
- the total cross-sectional area of all web sections 14 of the individual expansion sections 9 is different.
- the bores 15 have the largest diameter in the expansion section 9 closest to the transition point 10, so that the overall web cross section of all web sections 14 is the smallest here.
- the diameter of the bores 15 are smaller; the overall cross-sectional area is therefore larger here. After all, they are
- the diameter of the bores 15 in the expansion section 9 closest to the end of the tension member 1 is even smaller and the overall cross-section of the web is larger.
- FIGS. 10 and 11 differs from that previously described
- Embodiment essentially only in that the web sections 14 'of each expansion section 9 bores 15' parallel to the surface of the band-shaped tension member 1 and transverse to its longitudinal direction.
- a bending section 16 directed transversely to the longitudinal direction of the tension member 1 is formed in each expansion section 9.
- the bending sections 16 of the individual expansion sections 9 have different bending stiffnesses.
- the bending sections 16 or bending beams are each formed between a slot 17 extending from the tension member 1 and a slot 17 extending from the opposite side into the anchor body 2.
- FIGs. 14 and 15 are the extension sections 9 between the clamping blocks 3 from Material with different modulus of elasticity (modulus of elasticity). Starting from the transition point 10, the modulus of elasticity of the material used for the expansion sections 9 increases, ie the spring stiffness of the expansion sections 9 increases towards the end of the tension member 1.
- the graded gradient of the anchor stiffness with the division into “load transmission zones” by composite and “expansion zones”, preferably without composite, serves to transfer only as much tensile force from the slat per load introduction zone as is transferred by the selected composite principle (adhesive + transverse pressure or friction + transverse pressure) can without taking damage. Thereafter, this load introduction zone eludes further stresses and the next by stretching the expansion zone behind it
- Load transfer zone is activated. Ideally, each load application zone derives a certain proportion of the total tensile force from the tension member. These are then collected in the anchor part until they are finally handed over to the component. The necessary strains in the
- Elongation zones must be achieved through adapted spring stiffness.
- the number of "clamps" to be connected in series is then determined according to the size of the load in the tension member and the permissible stress of the selected composite principle (adhesion / cohesion or pure friction of anchor surfaces with the tension member). Compared to conventional gluing without alternating arrangement of load transfer and expansion compensation, the full length of the glue joint is activated.
