Definitions
- This invention relates to a method for producing prestressed concrete components in new constructions (cast in situ on the construction site) or in the prefabrication and for the subsequent reinforcement of existing structures by means of cementitious mortars, in which profiles of shape memory alloys, among professionals often referred to as shape memory alloy profiles, in short SMA profiles, for preloading. With this preload system, subsequent attachments can be attached to an existing structure under prestress.
- the invention also relates to a concrete structure that created using this method or subsequently reinforced resp. to which attachments were docked by this method.
- shape memory alloys based on steel in the form of profiles are used for generating a prestress.
- a bias within a building generally increases its serviceability by reducing cracks or preventing cracking at all.
- Such a bias is already today Reinforcement against the bending of concrete parts or for lashing example of columns to increase the axial load resp. used for shear reinforcement.
- Another application of the prestressing of concrete are pipes for liquid transports and silos respectively.
- Tank container which are tied to produce a bias voltage.
- For prestressing in the state of the art round bars or cables are inserted into the concrete or subsequently fixed externally on the surface of the component on the tension side.
- the anchoring and force from the biasing element in the concrete is very complex in all these known methods. High costs for anchoring elements (anchor heads) are incurred.
- anchor heads anchor heads
- the object of the present invention is therefore to provide a method for tempering new concrete structures and concrete components or cement-bonded Vermörtelept for the reinforcement of existing structures, either to improve the serviceability and stability of the structure, to ensure a more flexible use of Building for subsequent overhanging attachments, or to increase the durability and fire resistance of the building. Further, it is an object of the invention to provide a concrete structure having biases or gains generated using this method.
- the object is first of all solved by a method for creating prestressed concrete structures by means of profiles of a shape memory alloy, be it of new concrete structures and concrete components or cement-bonded Vermörtelept for the reinforcement of existing structures, which is characterized in that profiles a steel-based shape memory alloy of a polymorphic and polycrystalline structure having a ribbed surface or having a surface in the form of a thread which can be brought to its permanent state as austenite by elevating its temperature from its state as martensite to the concrete or the cementitious mortar be optionally with additional end anchorages, so that they either due to a subsequent active and controlled heat input with heating means or or by heat in a fire, a contraction force and thus generate a tensile stress and e loom a bias on the concrete resp. generate the Vermortelung, with the introduction of force into the concrete or mortar on the surface structure of the profile and / or on the end anchors of the profile takes place.
- a concrete structure created using one of the preceding methods, which is characterized in that it contains profiles of a shape memory alloy in a new concrete or in a grouting applied as a reinforcing layer of a building exterior, the run along the outside of the building within the Vermettelung or reinforcing layer and are biased or prepared for a bias by heat input by electric cables are led out of their end portions of the grouting or reinforcing layer or their end portions are accessible by removing deposits.

- shape memory alloys must. Shape Memory Alloy (SMA)]. These are alloys that have a specific structure that can be changed depending on the heat, but that returns to their initial state after heat dissipation. Like other metals and alloys, shape memory alloys (SMA) contain more than one crystal structure, so they are polymorphic and thus polycrystalline metals. The dominating crystal structure of shape memory alloys (SMA) depends on the one hand on their temperature, on the other hand on the externally acting tension - be it train or pressure. At high temperature it is an austenite, and at the low temperature it is a martensite.
- SMA shape memory alloys
- the transformation temperatures at which the structure of the shape memory alloy (SMA) changes may vary considerably depending on the composition of the shape memory alloy (SMA).
- the transformation temperatures are also load-dependent. With increasing mechanical load of the shape memory alloy (SMA) also its transformation temperatures rise. If the shape memory alloy (SMA) is to remain stable within certain load limits, then great attention must be paid to these limits.
- shape memory alloys (SMA) are used for structural reinforcement, the fatigue quality of the shape memory alloy (SMA), in addition to corrosion resistance and relaxation effects, must be taken into account, especially if the loads vary over time.
- Structural fatigue involves the accumulation of microstructural defects as well as the formation and propagation of surface cracks until the material eventually breaks.
- Functional fatigue is the result of the gradual degradation of either the shape memory effect or the damping capacity due to microstructural changes in the shape memory alloy (SMA).
- SMA shape memory alloy
- the latter is associated with the modification of the stress-strain curve under cyclic loading.
- the transformation temperatures are also changed.
- Shape memory alloys (SMA) based on iron Fe, manganese Mn and silicon Si are suitable for taking up permanent loads in the construction sector, with the addition of up to 10% chromium Cr and nickel Ni making the SMA a similar one Corrosion behavior brings like stainless steel.
- shape memory alloy made of Fe-Ni-Co-Ti, which absorbs loads of up to 1000 MPa, is highly resistant to corrosion, and has an upper temperature of about 100 ° C. to convert it to an austenite state is.
- the present reinforcement system utilizes the properties of shape memory alloys (SMAs), and preferably those of a shape memory alloy (SMA) based on steel much more corrosion resistant than structural steel, because such shape memory alloys (SMAs) are essential are cheaper than about SMAs made of nickel-titanium (NiTi).
- SMAs shape memory alloys
- the steel-based shape memory alloys (SMAs) are used in the form of round steels with rough surfaces, for example with coarse threaded surfaces, and embedded in a mortar, ie a mortar layer, which subsequently acts as a reinforcing layer through a toothing with an underlying concrete. When heat is applied, the alloy contracts permanently back to its original state. Thus, heating the SMA profiles to the austenite state temperature will restore and retain their original shape, even under load.
- a steel profile made of a shape memory alloy in short a SMA steel profile, preferably made of round steel with ribbed surface or with a coarse thread surface as new construction or in the prefabrication instead of a traditional reinforcing steel or in addition to the concrete is inserted. After the concrete has hardened, the SMA steel profile is heated by supplying electricity.
- the SMA steel profile is attached to the roughened surface of the concrete structure in any direction, but mainly in the direction of pull, and pegged with the same, and then fully enclosed and covered with a cementitious mortar or shotcrete.
- the SMA steel profiles are heated by means of electricity, which leads to the shortening of these SMA steel profiles.
- the shortening causes a bias of cement mortar or mortar layer. From the mortar layer, the forces are then introduced into the existing concrete due to the rough surface of the concrete structure and the adhesion.
- the invention can also be applied to better protect a building in case of fire, for which purpose the direct contraction of the SMA steel profiles by heat input is initially deliberately omitted. In case of fire, however, the installed SMA steel profiles contract due to the heat of the fire. A building envelope made of concrete, which with SMA steel profiles was amplified, thus automatically generates in case of fire, a bias and thus an improvement in fire resistance.
- FIGS. 1 shows a cross section of a concrete slab or a concrete beam 1.
- SMA steel profiles 2 are embedded.
- Steel-based SMA profiles 2 of polymorphic and polycrystalline structure are always used, with a ribbed otherwise textured surface, or with a thread as the surface. By raising their temperature, these SMA steel profiles can be brought out of their state as martensite to their permanent state as austenite.
- Such a concrete component can be produced on site at the construction site or even in a prefabrication.
- the built-in SMA profiles 2 in the form of round steels have a coarse surface structure 4, so that they can dig into the concrete intimately with the same.
- the SMA steel profiles 2 are heated by heat input. This is advantageously done electrically by establishing a resistance heating by applying a voltage to the cast-in heating cable 3 so that the SMA steel profile 2 heats up as a current conductor. Because with long SMA profile bars the heating would take up too much time by means of electrical resistance heating, and then too much heat would be introduced into the concrete, several power connections are established over the length of the SMA profile bar.
- the SMA steel profile can then be heated in stages by applying a voltage to two adjacent heating cables, and then to the next two adjacent ones, and so on, until the entire SMA profile bar is brought to the austenite state short-term high voltages and currents required, so that a normal mains voltage of 220V / 1 10V is not sufficient, even a voltage source of 500V not, as it is often set up on construction sites. Rather, the voltage is supplied by an on-site mobile energy unit that generates the voltage with a number of series connected lithium batteries with sufficiently thick power cables so that a high amperage current can be sent through the SMA steel profile.
- the heating should be done only for a short time, so you have within 2 to 5 Seconds throughout the required temperature of about 150 ° to 300 ° in the SMA steel profile 2 achieved and thus generates its contractile force. This prevents the subsequent concrete from being damaged.
- two conditions must be adhered to, namely firstly about 10-20 A per mm 2 of cross-sectional area and secondly about 10-20 V per 1 m of profiled rod length in order to reach the condition of the profiled rod as austenite within seconds.
- the batteries must be connected in series.
- the number, the size and the type of batteries must be selected accordingly, so that the required current (ampere) and the required voltage (volts) are available, and the energy reference must be controlled by a controller, so at the touch of a button - tuned to a certain profile steel length and profile steel thickness, just the right period of time the profile bar is under tension and the necessary current flows.
- the heating can be done in stages by power connections are provided after certain sections, that is, out of these heating cables from the device to be created are led into the open, where then the voltage can be applied. In this way, in sections - one section after the other over the total length of a profile bar, the heat needed to be used to finally put the entire length in the state of an austenite.
- Figure 2 shows a cross section of an alternative embodiment of such a concrete component.
- inserts 5 may be, for example, pieces of wood which are inserted over the end regions of the SMA round steel bars 2, or styrofoam pieces or the like.
- these inserts 5 can be removed and then the access to the end regions of the SMA steel profiles 2 is exposed. They can then be heated by applying the electrical cables of the energy unit to these end areas via large-area terminals.
- the immediate heat input can be dispensed with. Then, such a concrete part 1 is preconditioned to a certain extent.
- the SMA profiles 2 If the effect of heat is later caused by the fire heat in a fire, the SMA profiles 2 generate a Contraction force and thus a tensile stress and thus generate a bias of the concrete, which leads to a significant improvement in the fire resistance of the building. In the event of fire, this will be clasped all around and will collapse much later, if at all.
- FIG. 3 shows a cross-section of a building wall 6, which in turn is traditionally reinforced with a conventional reinforcement 7, 8.
- the outside 9 of the building wall 6 is executed rough here or subsequently roughened. This can be done for example by means of a wet sandblasting.
- a better variant is the hydromechanical treatment with the high-pressure water jet. Different systems with different amounts of water and water pressures of at least 500bar to 3000bar are used in practice. With such systems, the desired roughness of the concrete surface of at least 3mm is ensured.
- the ground support concrete is capillary water saturated. This is a condition for good adhesion between the existing concrete and the cement-based mortar layer to be applied.
- Figure 4 shows how then the SMA profiles 2 are attached in the form of round steel with a corresponding alloy on the rough surface 9. They can be fastened with dowels 10 in the concrete wall. If necessary, the dowels 10 can also reach behind the first reinforcement 7, 8.
- the two end portions of the individual SMA profiles 2 are each connected to electric cables 3. Although only a single SMA profile 2 is visible here, which extends vertically, it is understood that horizontally extending, indeed running in any direction SMA profiles 2 can be installed, as well as the reinforcement in the concrete wall 6 here horizontally extending reinforcing bars 8, which intersect with the vertically extending reinforcing bars 7.
- the SMA profiles as shown in Figure 5, completely wrapped by applying shotcrete or cement mortar, through Spraying, pouring or topping.
- the cement mortar can also be applied by hand.
- FIG. 6 shows, here at one point on the SMA profile 2, a recess 1 1 can be seen, in which an insert 5 was used. After this has been removed after curing of the concrete or mortar, the SMA profile 2 is exposed there. The heat input then takes place via a there to be connected by means of a terminal heating cable in conjunction with another heating cable, which is connected to a similar recess point via a terminal to the SMA profile.
- the SMA profile 2 is placed on the two marked heating cable 3 under an electrical voltage, so that a resistance heating is formed.
- the heating leads to a contraction force of the SMA profiles 2, which thus generate a tensile stress and thus a bias of the entire grouting or reinforcing layer 16, and their bias is transmitted via the teeth with the rough surface 9 of the concrete wall 6 on the same. Overall, a significant reinforcement of the structure is achieved.
- Figure 7 shows a cross section of this building wall after generating the contraction force and tensile stress of the SMA profiles 2 within the grouting or reinforcing layer 16.
- the recess 1 which was used for the heat input be, is now with cement mortar filled. In the case of heating cables 3, these are cut flush with the surface.
- Figure 8 shows a cross section of a steel-reinforced building wall 6, which is reinforced on a vertical outside with a sprayed layer, which in turn is biased by means of SMA profiles 2.
- a grid of SMA profiles 2 is attached to the roughened surface of the concrete 6, for example by means of suitable dowels 10. Afterwards, this grid is as shown by means of shotcrete from a spray gun 21 sheathed and covered. After curing of this shotcrete, the SMA profiles 2 of the grid are contracted by heat input, so that the whole shotcrete layer is biased as a reinforcing layer 21. The generated preload is over the teeth with the roughened surface of the structure 6 transferred to the same and thus significantly increases its stability and fire resistance.
- FIG. 9 shows an application on a horizontal concrete slab.
- these SMA profiles 2 can be cast with a manually applied liquid mortar.
- a self-compacting and self-leveling cementitious mortar may be used.
- the cast-in SMA profiles 2 are heated by heat input and produce a nationwide bias of the mortar layer, which transfers to the concrete slab.
- Figure 10 shows a section of a concrete slab 12, namely a corner thereof seen in a perspective view from below, which is provided on its underside with a pegged and prestressed reinforcing layer 19 containing SMA profiles.
- the reinforcing layer 19, which contains SMA profiles as described, is non-positively connected to the concrete slab 12 by means of a plurality of dowels 13.
- Figure 1 1 shows the internal structure of this reinforcement with a cross section through the concrete slab 12 of Figure 10, with the conventional reinforcement made of reinforcing steels 7.8, as well as the doweled and prestressed reinforcing layer 19 with SMA profiles 2.
- the underside the concrete slab 12 is rough, and the SMA profiles 2 are embedded in the sprayed-on reinforcing layer 19.
- the dowelling takes place by means of long concrete dowels 13, which reach behind the first reinforcement 7,8 in the concrete slab 12.
- the bias of the SMA profiles 2 which transmits to the reinforcing layer 19, and from there via the teeth with the rough surface of the concrete slab 12 and the doweling on the same.
- the thus prestressed concrete slab 12 has a significantly higher load capacity and so existing concrete slabs can be efficiently reinforced from below.
- Figure 12 shows a concrete beam with a subsequently applied reinforcing layer 19, the two ends is pegged.
- the bias should act only in one direction, namely between the two support points of the concrete beam.
- FIG 13 Another interesting application is shown in Figure 13.
- SMA profiles 2 or ordinary reinforcing steel biased.
- the outer end of the reinforcement which faces towards the building outside, is equipped with a coupling member 22.
- SMA profiles 2 leads an electric cable 3 in the concrete to the rear, concreted end of the SMA profile 2.
- These coupling members 22 may be double nuts, for example. They are embedded in concrete and only slightly covered with concrete. If you want to later dock a cantilevered concrete slab 15 to the structure 14, the coupling members 22 are exposed and a concrete slab 15, in which SMA profiles 2 were poured, is connected to the concrete plant 14.
- the gap between the structure 14 and the cantilevered concrete slab 15 is filled.
- heat is introduced into the SMA profiles 2 via electric cables, so that they generate a contraction force and thus a tensile stress.
- the whole system is biased, that is, the cantilevered concrete slab 15 is internally biased, and also stretched by means of a bias to the structure 14, and if the entering into the structure reinforcements are also SMA profiles 2, so These also generate a prestress in the interior of the structure 14, which leads to a high stability and load capacity of the projection.
