Definitions

  • the present invention relates to a thermal insulation component according to the preamble of patent claim 1.
  • components for thermal insulation are known in the prior art, which are primarily used to support building parts that protrude from buildings, such as balcony slabs, through a thermally insulated component joint.
  • the integrated reinforcement elements ensure the necessary force and torque transmission, while the insulating body is responsible for thermally insulating the two components while leaving a joint.
  • tensile reinforcement elements are provided in the relevant state of the art, which are usually made of a rod material made of metal, which consists of stainless steel in particular in the area of the insulating body and of reinforcing steel in the area outside the insulating body.
  • Stainless steel is used in the area of the insulator or the component joint on the one hand because of its corrosion resistance and on the other hand because of its poor thermal conductivity and is therefore preferable to reinforcing steel material in the area of the insulator.
  • the reinforcing steel material on the other hand, is mostly used in the area outside of the insulating body, where neither corrosion resistance nor thermal insulation properties are important, since the reinforcing steel extends completely in the area of one of the two components.
  • tensile reinforcement elements which until then had almost exclusively been made of metal, from plastic material, since this is significantly cheaper than stainless steel and also has a poorer thermal conductivity than stainless steel.
  • An example of such a building element for thermal insulation with tensile reinforcement elements made of plastic material is DE-U 20 2012 101 574 to remove.
  • the tensile reinforcement elements referred to in this document as strain relief rods are made of glass fiber reinforced plastic, with two adjacent rods being able to be connected to one another at their ends via a transverse plate in order to achieve a higher and more stable transfer of tensile force.
  • tensile reinforcement elements made of glass fiber or carbon fiber reinforced plastic material can be found in the WO-A 2012/071596 in which a device for connecting reinforced concrete slabs to a wall or ceiling construction made of reinforced concrete has tensile reinforcement elements which consist of closed loops which, due to their loop shape, form a positive connection with the adjacent component and thus ensure the necessary anchoring.
  • Loop-shaped tensile reinforcement elements have been proposed again and again in the prior art; However, due to their short bond length in the adjacent component and their resulting reduced ability to transfer greater tensile forces, they had significant disadvantages, with the loop shape itself regularly causing a collision with the connecting reinforcement and thus causing installation problems, similar to the transverse plates described above.
  • bending pressure shear elements which can be made of UHPFRC quality concrete and which are spatially separated from the loops.
  • the adjoining component which in turn causes installation problems due to the connection reinforcement to be arranged in this area; or you have to try to provide the tensile reinforcement elements made of fiber-reinforced plastic made of pipe or rod material with profiling or ribbing provided on their outside, whereby the anchoring of these ribbed plastic tensile reinforcement elements in the adjacent component suffers from the fact that the fiber-reinforced plastic on the one hand and
  • the concrete material of the adjoining component usually has such significantly different coefficients of thermal expansion that inevitably different temperature-related relative movements occur, which cause stresses or expansions in the mutual contact area. This leads to destruction by shearing off either the ribs or the so-called concrete brackets between the ribs. From this it follows that the tension reinforcement elements can no longer fulfill their function.
  • a further disadvantage of the tensile reinforcement elements made of plastic material is the lack of subsequent bendability in comparison to steel, which makes it necessary for the desired shape and length of the tensile reinforcement elements to be taken into account already during bar production. As a result, the number of tensile reinforcement elements to be kept in stock increases due to a correspondingly higher number Considerable number of variants, which means significant disadvantages in terms of logistics.
  • the EP 2 821 558 A1 shows a component for the heat-insulating connection of two parts of a building, in particular between a building and an outer part, such as a balcony, which protrudes beyond the building, with a plate-shaped insulating body. Loop-shaped pull elements are used in these, which protrude beyond the insulating body on both sides. In addition, pressure bodies and bodies absorbing transverse forces are inserted into the insulating body, which have areas protruding beyond the insulating body and which are spatially separated from the loop-shaped pulling elements.
  • the reinforcement elements are designed as multi-part composite elements, wherein in addition to the central section, they have at least one anchoring section with geometric and/or material properties that at least partially deviate from the central section in a region outside of the insulating body, which is connected to the central section in a connection region spaced apart from the insulating body via a wound form element is connected, and that the former abuts against the central portion.
  • the above-mentioned multi-part composite element with an unusual mix of materials, in that it consists, at least in the area of the insulating body, of a corrosion-resistant and very poorly thermally conductive fiber-reinforced plastic material in the form of a loop-shaped middle section that protrudes from the insulating body and in that it is in an area outside of the insulating body in the adjoining component has an anchoring section which has different materials and/or geometries than the central section and can be adapted to the installation conditions in the adjoining components, as has been proven in the case of conventional metal rebars, which, however, are usually in the area of the insulating body have a center section made of stainless steel.
  • this composite element surpasses the previously known tensile reinforcement elements in every respect, as it makes it possible to select the materials used for the different requirements in the insulating body or in the adjacent components with regard to their individual advantages and to be able to ignore disadvantageous materials or geometries.
  • a middle section made of fiber-reinforced plastic can be used, which is cheaper and has significantly poorer thermal conductivity than the stainless steel used previously, while there are no special requirements in the area of the adjacent concrete components and therefore the inexpensive, easy-to-handle and subsequently bendable reinforcing steel rods, which can also be easily and inexpensively adapted to optimal anchoring in the adjacent concrete components with the appropriate external profile.
  • the anchoring section is connected to the central section via the coil form element and that the coil form element on the central section is at least indirectly applied. It is particularly advantageous in this context that the winding form element rests against the middle section without play and/or in a form-fitting manner and/or over the surface, with a material connection being possible, for example by welding the winding form element to the anchoring section.
  • What is essential is the direct operative connection between the winding form element and the middle section, through which the tensile forces are transmitted directly and without relative movement between the two elements. The larger the contact surface between the winding form element and the middle section, the better the tensile forces can be transmitted, which are then distributed over a larger cross section.
  • the winding form element acts on the loop-shaped central section at least partially in the apex or deflection area of the loop form, namely where the anchoring section would act on the loop-shaped central section if the tensile load were unimpeded.
  • the winding form element can ensure that the anchoring section is connected to the middle section in the appropriate area, namely the apex or deflection area thereof, and reliably transmits the forces that occur.
  • the winding form element consists of a winding form element that is used in any case in the production of the middle section, the required backlash-free and, in particular, flat contact can be ensured in a simple manner.
  • the winding-forming element serves as a deflection element or as a winding core in order—in particular together with a further deflection element or winding core—to produce the desired loop shape. If the winding form element remains on the fibers, the fibers lie flat on the winding form element with the surrounding plastic material of the middle section where the middle section forms an adhesive bond with the wound form element when it is wet wrapped around it, which is sufficient to secure it during transport and as a safeguard against loss, to prevent the middle section from being removed or detached from the wound form element during transport, installation and concreting.
  • the wound form element rests not only until the end of the drying process, but according to the invention also until installation and subsequent concreting as part of the component for thermal insulation on the central section, where it is then separated from the material of the associated component, i.e. in particular from concrete is enclosed.
  • the surface of the winding form element in the area of contact with the middle section is uniform and flat, with the surface plane being adapted to the curved course of the middle section loop in the apex area, i.e. being curved in the same way.
  • the surface plane can thus have the shape of a segment of a cylinder jacket surface, for example.
  • the surface plane can also be bulbous, whereby it corresponds more to the shape of a segment of a torus jacket surface.
  • a winding element primarily means an element that is adapted to the loop-shaped middle section, particularly with regard to the shape in the connection and contact area, in order to ensure particularly good and reliable power transmission without compromising the other advantages of the composite element, such as the modular structure made of different materials and shapes could not offer.
  • a wound form element within the meaning of the invention is also such an element which, regardless of its shape, is used for the force-transmitting connection of an anchoring section to the middle section, the very different embodiments described here and illustrated in the drawings are possible for the anchoring section.
  • a particularly advantageous operative connection results when the coil form element arranged between the anchoring section and the middle section bears flat not only on the middle section but also on the anchoring section.
  • the shaped winding element In addition to the described planar contact area for the middle section, various geometries are conceivable for the shaped winding element, which are primarily based on the additional tasks: If the shaped winding element is also acted upon by the anchoring element over a wide area, the shaped winding element should be adapted to the surface shape of the anchoring element in the contact area. Since the middle section and the anchoring element engage with one another with the interposition of the former, the contact area for the anchoring element is arranged on the opposite side of the contact area for the middle section in the case of the former.
  • the contact area should also be designed evenly and evenly and be curved.
  • the surface plane then has the shape of a segment of a torus envelope surface. If, on the other hand, the anchoring element is bent in a U-shape, but consists of a reinforcing bar with a rectangular cross section, then the surface plane has the shape of a segment of a cylindrical jacket surface.
  • the anchoring sections are preferably made of steel, in particular reinforcing steel, they can be anchored in the adjoining components in a conventional manner without - as in the case of fiber-reinforced plastic rods - by exotic forming (in the form of the mentioned transverse plates, loops, etc.) and Installation problems with the connection reinforcement caused by this would have to be paid for or, when using profiled plastic rods, due to damage in the mutual contact area, which the different coefficients of thermal expansion of concrete on the one hand and plastic rod on the other.
  • the structural element according to the invention with the tension reinforcement elements designed as a composite element, in that the tension reinforcement elements consist of the loop-shaped central section protruding only slightly in relation to the insulating body and the anchoring section connected thereto. Only the anchoring section overlaps the connection reinforcement, which can then be designed in such a way that on the one hand installation problems such as collisions with the connection reinforcement are avoided and on the other hand the anchoring in the adjacent component is optimized.
  • the anchoring is usually carried out by ribbing the outer surface of the reinforcing bars, and this ribbing can be easily introduced during the manufacturing process of these reinforcing elements.
  • the anchoring section of the tensile or shear force reinforcement elements consists of a rod-shaped anchoring element bent in particular in a U-shape, that the anchoring element is hooked into the loop shape of the middle section and that the coiled-form element at least partially fixes the U-shaped bent rod-shaped anchoring element in its U-apex area applied, that is in the area of the U-shaped bend.
  • each reinforcement element has a central section with two sections running parallel to one another, which can also be used for force transmission.
  • the middle section has two loop subsections which extend in the horizontal direction (or in the case of the shear force reinforcement element essentially inclined to the horizontal) essentially parallel to one another, preferably next to one another and/or one above the other and are connected to one another via the apex region, each of which absorbs part of the force to be transmitted .
  • the power transmission can be increased compared to a conventional reinforcing bar - and with the same cross-section of the reinforcing bar on the one hand and the individual loop section on the other even double.
  • a loop consists of about 50 fiber wraps.
  • each loop section has these 50 filament wraps, a total of 100 filament sections extend between the two adjacent members, which of course means that such a tensile reinforcing element can correspondingly transmit twice as many forces as a single 50-filament tensile reinforcing bar.
  • the loop shape of the middle sections can not only be used advantageously for connection to U-shaped anchoring elements, but also for fixing an end anchoring element that protrudes laterally relative to the middle section, i.e. transversely to the longitudinal extent of the middle section, and which can also function as an anchoring section.
  • This end anchoring element is in particular connected in one piece to the winding form element and essentially serves to enlarge the surface of the central section in the apex area by means of laterally protruding sub-areas and also to enable anchoring of the tension or shear force reinforcement element in the associated component without additional rod-shaped reinforcement elements, as is shown by the Anchoring plates of the prior art is known per se. It is important here that this end anchoring element forms a structure which, due to its geometry, absorbs occurring tensile loads in a form-fitting manner and is supported in the concrete of the adjacent component.
  • the end anchoring element expediently has a cross section oriented parallel to the insulating body, which is larger than the cross section of the middle section and forms laterally protruding end anchoring sections in order to anchor the tensile or shear force reinforcement element, as in the known anchoring plates in the component by, on the one hand, increasing the surface area of the reinforcement element and thus the force transmission area and, on the other hand, by forming partial areas of the reinforcement element which the component engages behind and form a form fit with.
  • the laterally protruding outer shape of the end anchoring sections can increase with increasing distance from the insulating body compared to the central section and can be designed like a fir tree, for example.
  • the anchoring of the tension rods or tension reinforcement elements in the associated concrete component can be improved and their binding length can thus be significantly reduced.
  • the end anchoring elements can consist of glass fiber reinforced plastic material.
  • the end anchoring elements it is also possible to produce them from concrete, in which case concrete should be understood to mean any form of a hardening and/or setting building material, in particular a cementitious, fiber-reinforced building material such as concrete, such as high-strength or ultra-high-strength concrete or such as high-strength or ultra-high-strength mortar, a synthetic resin mixture or a reaction resin mixture.
  • the anchoring section of the reinforcement elements is expediently fixed at a free end of the associated central section. If, in this case, the anchoring section of the reinforcement elements is arranged in alignment with this central section, which extends essentially horizontally when the component is installed, this results in the different parts of the reinforcement elements being arranged one behind the other or in series, with each part being arranged where it is most favorable has material properties.
  • the anchoring section consists of reinforcing steel, which has a thermal expansion coefficient, i.e. thermal expansion, in the order of magnitude of the thermal expansion coefficient or thermal expansion of concrete and thus non-destructively corresponding temperature-related Deformations or expansions of the concrete can follow.
  • the middle section of the tensile or transverse force reinforcement element consists of fiber-reinforced and in particular glass-fiber-reinforced plastic material, which on the one hand can be sufficiently loaded in the direction of tensile force is and on the other hand has a poor thermal conductivity, which is desirable in the area of the insulating body.
  • the wording "fibre-reinforced plastic material” also includes fiber reinforcements, in particular glass fiber reinforcements, whose fiber content, in particular glass fiber content, is higher than 85% by weight, so that the weight of the matrix material used in addition to the fibers, such as synthetic resin, is less than 15% compared to the weight of this reinforcement element.
  • the anchoring sections Since the reinforcing steel of the terminal anchoring sections must have a minimum concrete cover for reasons of corrosion protection, the anchoring sections must not extend as far as the insulating body in order to avoid corrosion of the anchoring sections. For this reason, it is expediently provided that the connection area, when installed, has a horizontal distance from the insulating body which is at least once and at most five times as great as the diameter d M of the middle section. As a result, the anchoring section can be fixed to the middle section outside of the insulating body in an area that is protected from corrosion by the required minimum concrete covering.
  • the middle section is expediently designed with essentially smooth walls on its radial outside, at least in the area between the insulating body and the connecting area. This avoids an excessive bond between the central section and the material of the adjacent component surrounding the central section, and forms a buffer zone which ensures that the flexural rigidity of the reinforcement elements does not change abruptly when leaving the insulating body and entering the adjacent component, but only gradually changes.
  • the essentially smooth-walled central section thus serves to prevent the reinforcement element from being anchored near the joint in the adjoining component, so that anchoring takes place only in the connection area and in the area of the reinforcement element following in the axial direction, namely the anchoring section.
  • the component for thermal insulation according to the invention expediently has pressure elements and/or transverse force elements in addition to the tensile reinforcement elements for the transmission of compressive force and/or shear force between the adjacent components - as is also known from the relevant prior art and as is usual with such structural elements for thermal insulation .
  • the material of the adjoining components i.e. in particular the building and the projecting outer part of concrete
  • this should be understood to mean any form of a hardening and/or setting building material, in particular a cementitious, fiber-reinforced building material such as concrete, such as high-strength or ultra high performance concrete or such as high performance or ultra high performance mortar, a synthetic resin mix or a reaction resin mix.
  • the Figures 1, 2 and 3 show a side view, perspective side view and top view of a component for thermal insulation 1 with a cuboid insulating body 2, which is intended to be arranged in a component joint left between two concrete components, namely a balcony A and a building ceiling B, and these two concrete components A, B spaced apart from each other in a thermally insulated manner.
  • the insulating body 2 is composed of several parts (not shown) in order to allow the installation of reinforcement elements in the form of tension rods 3 , in the form of transverse force rods 4 and in the form of pressure elements 5 .
  • the reinforcement elements are arranged in the manner known and customary in the prior art, namely by arranging the tensile reinforcement elements 3 in the upper region of the insulating body 2, which extend in the horizontal direction when installed and for the transmission of tensile forces between the two to the component serve for thermal insulation connected components A, B and are anchored in these components for this purpose.
  • the pressure elements 5 are arranged, also with a substantially horizontal direction of extension, although in the exemplary embodiment shown they do not essentially protrude in relation to the insulating body 2.
  • shear force rods 4 are to be used in the usual manner, which run inclined to the horizontal in the area of the insulating body 2 and from the reinforcement elements The loads to be absorbed by the component for thermal insulation run diagonally downwards from the tension zone on one side of the insulating body into the compression zone on the other side of the insulating body, where it bends vertically upwards in the direction of the tensile zones and then, after a further bend, parallel to the tensile reinforcement elements to get lost.
  • the tensile reinforcement elements 3 which are constructed as a multi-part composite element and have a loop-shaped central section 3a made of fiber-reinforced plastic and an anchoring section 3b in the form of a U-shaped rod material at one end and an anchoring section at the other end have an end anchoring element 3c.
  • the middle section 3a extends horizontally in the area of the insulating body 2 and protrudes somewhat horizontally on both sides of the insulating body 2 and is arranged with this protruding area in the area of the adjoining components A, B in the installed state.
  • Central section 3a and anchoring section 3b each overlap in a connection area 3h with the interposition of a winding form element 3i.
  • This winding former serves to allow the fibers to change direction when the loop-shaped central portion 3a made of fiber reinforced plastic is formed, and to form a crest portion 3k by constituting the shape around which the wet fibers are wound. If two such winding form elements 3i are used, the overall loop shape can be obtained, consisting of two loop sections 3g which extend essentially parallel to one another and are connected to one another at their ends via a respective apex region 3k.
  • winding form element Since the winding form element remains in the apex areas after the production and drying of the loop-shaped middle section, it also lies flat against the associated apex area of the middle section when installed and ensures play-free transmission of tensile forces between anchoring section 3b and middle section 3a.
  • connection area 3h in which the middle section 3a and the anchoring section 3b consisting of rod material bent into a U-shape overlap, but also in the opposite connection area 3h, where middle section 3a and overlap an end anchoring element 3c acting as an anchoring section.
  • the end anchoring member 3c As for the end anchoring member 3c, it has an inner portion functioning as a coil-forming member 3i while having laterally protruding end anchoring portions 3m. As a result, the anchoring of the tension rods or tension reinforcement elements 3 in the associated concrete component and thus their binding length can be significantly reduced.
  • the anchoring element 3b consisting of rod material bent in a U-shape is arranged oriented in the horizontal direction, just like the middle section 3a, but with the apex axis of the apex region 3k offset by 90° on the one hand and the U-base of the rod material bent in a U-shape on the other hand.
  • both elements can be plugged into one another in a crossed, aligned manner with one another.
  • the middle section 3a with its plastic material extends somewhat beyond the insulating body and thus enables the anchoring section 3b made of reinforcing steel to be connected to this middle section 3a in an area which is not yet at risk of corrosion.
  • Significant advantages can be achieved in this way: In the area of the insulating body, the particularly advantageous plastic material of the central section can be used, which is characterized above all by lower costs and particularly poor thermal conductivity compared to high-grade steel.
  • the anchoring sections can finally consist of reinforcing steel in the area of the components, which has similar thermal expansion coefficients to the component concrete surrounding it and can therefore form an optimal connection with the concrete, through which the tensile force from the concrete into the tensile reinforcement element and the opposite can be transferred without causing the destruction that would otherwise occur due to excessive relative movements.
  • the end anchoring element 3c′ also has a winding form element 3i in its inner or central region acted upon by the loop-shaped central section 3a.
  • the Figures 10, 11 and 12 finally show an alternative component 31 for thermal insulation, in which the same objects and components as in the drawings mentioned before with the same reference numerals as in particular in the Figures 1 to 3 are listed.
  • the only difference between the component 31 and the component 1 from the Figures 1 to 3 consists in the fact that not only the tensile reinforcement elements 3 are designed as a composite element, but also a transverse force element 14. This consists of a central section 14a made of a loop-shaped, fiber-reinforced plastic element and an anchor portion in the form of an end anchor member 14c.
  • the transverse force element middle section 14a like the tension reinforcement element middle section 3a, is wound from endless fibers with the aid of a winding form element 14i, which serves to enable the fibers to change direction when the loop-shaped middle section 14a is produced and to form a crest region 14k by representing the shape around which the wet fibers are wrapped. If two such winding form elements 14i are used, the overall loop shape can be obtained, consisting of two loop sections 14g which extend essentially parallel to one another and are connected to one another at their ends via a respective apex region 14k.
  • the present invention offers the advantage of providing a component for thermal insulation that has tensile and/or shear force reinforcement elements in the form of multi-part composite elements, which consist of a central section made of loop-shaped, fiber-reinforced plastic material on the one hand and at least one additional anchoring section.
