Definitions
- the present invention relates to a drivable structure with a first partial structure and a second partial structure that can be moved relative thereto.
- the first substructure comprises a first substructure and a first roadway structure forming a first trafficable surface
- the second substructure has a second substructure and a second roadway structure forming a second trafficable surface.
- the respective substructure can also be referred to as "supporting structure" - there is an expansion joint, with a bridging structure spanning the expansion joint between the first roadway structure and the second roadway structure with a support plate and a supported by this, cast on site from casting compound, extending a trafficable surface forming expansion body.
- Bridges or similar structures come into consideration as trafficable structures in the above sense, but in particular driveways or access routes to (earthquake-proof) buildings and between building parts of a building complex (e.g.
- navigability and “roadway” in the sense of the present invention do not necessarily mean navigability with motor vehicles, in particular with heavy motor vehicles; Rather, less loaded applications that can only be driven on or walked on with light vehicles (bicycles, scooters or the like), including
- the first part of the structure can be designed as a structure that is firmly connected to the subsoil and the second part of the structure can be designed as a part of the building that is seismically decoupled from the subsoil.
- the first part of the structure can be designed as an abutment and the second part of the structure can be designed as the superstructure of the bridge.
- the bridging structure bridges the expansion joint, which is variable in its dimensions (e.g. due to thermal expansion and/or seismic activity and/or shrinkage or creep phenomena), by means of a support plate and expansion body and in this way enables the expansion joint to be traversed on an uninterrupted surface .
- Such bridging structures with a support plate and an expansion body supported by this, cast on site from casting compound and forming a trafficable surface or trafficable structures in the above sense are known from the prior art - for example, see EP 2 483477 B1 and CH 691496 A5 referenced.
- the working direction of an expansion joint is a direction in which the dimension of the expansion joint (expansion joint width) changes as intended.
- the working range of such a bridging structure is limited by the minimum extension of the expansion joint in the working direction (at the maximum permissible compression of the expansion body) on the one hand and the maximum extension of the expansion joint in the working direction (at the maximum permissible expansion of the expansion body) on the other.
- there are further relative movements of the two Partial structures in relation to one another are not excluded, namely transverse and/or vertical displacements.
- the object of the present invention is to provide a structure of the type described above that can be driven on, which is characterized by improved practicality compared to the prior art, in particular with regard to low production, installation and maintenance costs and a particular suitability for cost-efficient and rapid renovation an existing bridging structure.
- the expansion body casting compound being polymer-based in a trafficable structure of the type described above, the expansion body having a multi-layer structure produced in several successive casting processes and at least two of the layers of the expansion body having different compositions.
- these special features bring about a hitherto unknown practical suitability.
- the expansion body is made of bitumen
- the expansion body casting compound has a polymer base which, in particular - in a particularly preferred embodiment of the invention - is made of PMMA (polymethyl methacrylate).
- PMMA polymethyl methacrylate
- PU polyurethane
- PU polyurethane
- an additive can in particular have filling bodies which comprise hard grain (eg corundum) and/or rubber granules (eg EPDM (ethylene propylene diene monomer) granules).
- the expansion body has several layers, with the compositions of at least two layers of the expansion body (or the compositions of the associated expansion body casting compounds) differing in particular in the polymer base used and/or the additives used. In this way, the material properties of the expanding body can be adapted layer-specifically through the layer-specific selection of the composition of the expanding body casting compounds.
- the individual layers of the expansion body are each produced in an independent casting process, in that castable expansion body casting compound is cast on site, i.e. in-situ on the construction site, and "solidifies” or “hardens” in the desired shape - whereby, in view of the intended compression -/extensibility of the finished expansion body “solidification” or “hardening” in the sense of a relative hardening compared to the state of the casting compound during processing (pourable consistency!) is to be understood.
- Two successive casting processes are timed in such a way that the expansion body layer produced in the previous casting process "cures", i.e. in particular crosslinks and/or can polymerize so that the layers do not mix, ie there is no mixing at the layer boundary.
- the layered structure of the polymer-based expansion body consisting of different types of layers can be achieved that a particularly durable and highly resilient bridging structure can be realized particularly quickly, easily and inexpensively.
- the larger surface-to-volume ratio of the individual layers of the expansion body, which is cast in several casting processes - compared to the complete expansion body - can have a very positive effect on the reaction time, especially in the case of an exothermic polymer base. In this way, i. H.
- the bridging structure realized according to the invention or the associated drivable building can be handed over to use or traffic more quickly, which is particularly the case in the case of renovation or repair work - which is often associated with sensitive use impairments of the building and significant traffic disruptions - can be a very big advantage.
- the larger surface-to-volume ratio of the individual layers of the expansion body and the associated efficient and rapid heat dissipation also enables the use of casting compounds that were previously unsuitable for expansion bodies for the application in question due to their strongly exothermic curing characteristics, namely because the exothermic heat development during curing comparatively poor heat dissipation would have led to heat damage in the structure or would have been accompanied by unacceptably long cooling or curing times.
- the present invention results in increased flexibility and an expanded spectrum of material pairings of base polymer/additive, which in turn enables optimal adaptation of the (multi-layer) expansion body to the individual requirements of the respective specific application.
- PMMA polymethyl methacrylate
- acrylic glass a plastic commonly referred to as "acrylic glass”
- PMMA silica
- the corresponding modification can, as is known per se, typically take place via suitable copolymers, with 2-ethylhexyl acrylate, for example, being able to produce elasticity-increasing effects.
- Elastic PMMA all the following statements relating to the use of PMMA as a base polymer for the expansion body refer to this - or PMMA-based polymer systems for the production of highly elastic structures are already the subject of patent literature and also - as PMMA systems for the production of fleece-reinforced coatings - commercially available (cf. for example the 2-component PMMA liquid plastic "BauderLIQUITEC PMMA Universal” from the range of Paul Bauder GmbH & Co.KG, Stuttgart or the 2-component PMMA sealing resin "ALSAN 770" from the range of Soprema GmbH, Mannheim).
- expansion bodies can be realized with (compared to PU) significantly improved expansion and compression properties.
- a PMMA expansion body can compensate for larger changes in length than a PU expansion body (of the same width) without being damaged in long-term applications.
- a specific, specified working area can be achieved with a narrower expansion body when using a PMMA polymer base for the expansion body than when using a PU polymer base.
- the expansion body has an elongation at break (mean value!) of at least 100%, particularly preferably at least 120%, in each of its layers, with the procedure for determining the elongation at break being in accordance with EN ISO 527-2 (1B) being aged samples without any other conditioning and 23°C sample temperature.
- the properties of the expansion body and its operating behavior can be designed so positively over long periods of time that, in typical applications, stabilizers embedded in the expansion body and extending across the expansion joint, as are known in the art (e.g. B. in the form of helical springs cast into the expansion body) are regularly provided, can be dispensed with.
- stabilizers embedded in the expansion body and extending across the expansion joint as are known in the art (e.g. B. in the form of helical springs cast into the expansion body) are regularly provided, can be dispensed with.
- this not only leads to cost advantages, but also in particular to further simplified and accelerated installation of the Bridging structure with correspondingly positive effects, especially for cases of renovation (reduced disruption to traffic).
- the casting compounds of the layers of the expanding body having different compositions are filled with different additives, with the casting compounds (of the layers of the expanding body having different compositions) particularly preferably having a matching polymer base. Due to the common polymer base, a particularly good adhesion of the layers of the expansion body to one another can be realized while at the same time achieving layer-specific material/operating properties due to layer-specific additives.
- an aggregate of the uppermost layer of the expansion body that forms the surface that can be driven on has harder fillers than an aggregate of a deeper layer of the expansion body.
- the uppermost expansion body layer that forms the surface that can be driven on can be designed to be particularly abrasion-resistant and non-slip, while the deeper expansion body layers have particularly good expansion and compression properties.
- the filling bodies of the uppermost layer of the expansion body can in particular include hard grain (e.g. corundum).
- the top layer of the expansion body consists of at least 80 percent by weight (% by weight), particularly preferably 95 percent by weight, of polymer and hard grain (total), since in this way - with good expansion and Compressibility of the expansion body layer in question and thus very low tendency to crack formation - a very particularly abrasion-resistant and non-slip surface can be realized.
- the weight ratio of hard grain to polymer is between 0.75 and 0.95, preferably between 0.8 and 0.9.
- the filling bodies of the aggregate of a deeper layer of the expansion body comprise EPDM granules and/or rubber granules.
- a deeper layer of the expansion body consists of at least 80% by weight, particularly preferably at least 95% by weight, of polymer and EPDM or rubber granules (total), with the weight ratio of EPDM or rubber granules to polymer in particular between 0.15 and 0.35, particularly preferably between 0.2 and 0.3.
- the bridging structure has two basic structures (already mentioned above) connected to the substructure of the respective substructure, with the support plate being accommodated between sections of the two basic structures that each form a border.
- the support plate can thus be embedded in the borders of the basic structures.
- the upper edges of the borders are essentially level with the surface of the support plate, an expansion body with an (at least almost) continuously level underside - and accordingly over the entire extent - can thus be achieved largely the same amount - can be realized.
- the basic structures can advantageously be stepped in such a way that they have support sections that extend under the support plate.
- the base structures can serve both as borders of the support plate and as supports (i.e. to transfer vertical loads) at the same time.
- the basic structures bring about a largely equalized load transfer, which—as a result of the reduction in load and stress peaks—benefits the service life of the bridging structure.
- the basic structures consist of polymer concrete, particularly preferably of a PMMA-based polymer concrete (e.g. ROBO®—DUR 42 from Mageba SA, Bülach, Switzerland). Because its characteristic material properties favor the function set out above.
- holding means for the expansion body are attached to the respective substructure (or to the basic structure placed on it), which support the edge-side fixation of the expansion body.
- Such holding means can optionally also be used for the connection of serve stabilizers embedded in the expansion body.
- Such stabilizers (or reinforcements) can include, for example, telescopic tubes which—fixed at the end to the angle rails forming the holding means—are preferably each surrounded by a spiral hose and/or are held under pretension by means of internal helical springs loaded with pressure.
- a further advantageous embodiment of the trafficable building according to the invention can be characterized in that the basic structures each have an adhesive surface for the expansion body that is essentially parallel to the working direction of the expansion joint, ie typically horizontally oriented.
- the expansion body can thus be attached to the respective basic structure, which also remains in place during the compression or expansion of the expansion body.
- there is no relative movement between the expansion body and the basic structure even if the expansion body is deformed. An ingress of dirt and water between the expansion body and the base structure (and thus further to the support plate) can be minimized in this way.
- the adhesive surfaces are also arranged in those areas of the expansion body close to the edge where it borders on the road structures, a gaping of the transition between the road structure and the expansion body when the expansion body is stretched can be counteracted in this way - regardless of the state of deformation of the expansion body. Furthermore, it can be provided that a seal existing between the substructure and the roadway structure of a partial structure extends under the associated basic structure. The appropriate overlapping of the base structure (in particular made of polymer concrete) and the seal counteracts the penetration of moisture under the base structure.
- a support plate not divided in the working direction of the expansion joint is provided, with a highly compressible filling strip extending along at least one end face of the support plate—related to the working direction of the expansion joint.
- a simple and cost-effective trafficable building according to the invention can be realized in this way.
- the support plate is fixed to the substructure of one of the two substructures.
- the support plate is designed to be divided in the working direction of the expansion joint and has two support plate sections each fixed to the substructure of one of the two substructures.
- the two fixed support plate sections can be designed to be interlocked, as a result of which a wave-shaped gap is formed between the two support plate sections.
- a third, free support plate section is accommodated between the two fixed support plate sections, which is interlocked on both sides with the respective adjacent fixed support plate section, in particular in the above sense.
- Such a three-part design of the support plate increases--in comparison to the two-part design--the number of gaps between the support plate sections from 1 to 2, as a result of which the specific gap width can be halved.
- This smaller gap width has advantages with regard to the drive-over characteristics and durability of the bridging structure.
- the advantages of the wave-shaped gap outlined above also apply here.
- support bodies cast on site below the support plate on the respective substructure.
- Such support bodies can in particular be designed as compensating layers cast from polyurethane, as a result of which the relevant support bodies have advantageous shock-absorbing characteristics.
- Support bodies of the type mentioned can be associated with advantages in terms of equalized load transfer if basic structures (cast on site, in particular from polymer concrete) of the type explained above (with lateral borders and lowered support sections for the support plate) are not implemented.
- a separating layer in particular an elastomer sheet (eg an EPDM film), is located between the support plate and the expansion body.
- an elastomer sheet eg an EPDM film
- the ability of the expansion body to slide freely and with as little friction as possible on the support plate promotes the uniform deformation of the expansion body to compensate for a change in the width of the expansion joint.
- the EPDM foil fulfills the separating function when casting the bottom layer of the expansion body. The separation between the expander and the support plate is maintained, even if the EPDM foil gradually dissolves during the use of the bridging structure. This can even have a beneficial effect in that the resulting EPDM powder has a friction-reducing effect.
- FIG. 1 shows a vertical section through the relevant area of a trafficable building according to a first exemplary embodiment
- 2 also in vertical section the relevant area of a trafficable structure according to a second embodiment
- the first exemplary embodiment of a structure 1 that can be driven on according to the invention comprises two substructures 2, namely a first substructure 2.1 and a second substructure 2.2.
- Each of the two substructures has a substructure 3 and a roadway structure 4, which forms a surface 5 that can be driven on.
- a seal 6 is provided between the respective substructure 3 and the associated road structure 4 .
- the two partial structures 2.1 and 2.2 are decoupled from one another in the sense that they can be moved relative to one another.
- 4.1 of the first partial structure extends between the roadway structure
- a bridging structure 9 that spans the expansion joint 7 and forms a surface 8 that can be driven on, with a deformable expansion body 10, namely one that can be stretched and compressed from a tension-free, neutral configuration in the working direction A.
- the expansion body 10 and the other components of the bridging structure 9 are in a " trough" which is bounded by the end faces 11 of the first track structure 4.1 and the second track structure 4.2 and the surfaces 12 of the first lower house 3.1 and the second lower house 3.2 which protrude in the direction of the central plane M.
- a base structure 13 made of polymer concrete is applied to each of the two substructures 2.1 and 2.2 on the respective substructure 3.
- the expansion joint existing between the first substructure 2.1 and the second substructure 2.2 extends upwards between the first basic structure 13.1 and the second basic structure
- the two basic structures 13 are stepped in such a way that they each have a recessed section 14 near the center plane M and a raised section 15 remote from the center plane M.
- the two elevated sections 15 form edgings 16 for a support plate 17 received between them, which—via interposed EPDM films F—rests on the recessed sections 14 of the two basic structures 13; the recessed sections 14 of the two basic structures 13 provide in this sense "Support sections”.
- the surfaces 18 of the frames 16 are essentially level with the surface 19 of the support plate 17.
- the support plate 17 does not completely fill the space existing between the skirts 16 . Rather, there is a gap 20 on both sides between the end face of the support plate 17 and the associated frame 16, in which a highly compressible filling strip 21 (e.g. made of foam rubber band) is inserted.
- the support plate 17 is thus movable relative to the two partial structures 2.1 and 2.2 in the working direction A of the expansion joint 7 and is therefore mounted in a floating manner.
- an angled perforated strip 23 is firmly connected to the associated substructure 3.1 or 3.2 by means of anchors 22 penetrating the respective basic structure 13 in the region of the relevant elevated sections 15.
- the respective horizontal leg 25 - provided with openings 24 - is supported in the area of its fastenings via spacer plates 26 on the surface 18 of the raised section 15 of the relevant basic structure 13, so that the angled perforated strips 23 are opposite the surface 18 of the associated basic structure 13 are aloof.
- the support plate 17 and the two filling strips 21 are on their - the expansion body 10 facing - upper side of a separating layer 29 in the form a (preferably self-adhesive) EPDM film 30 covered.
- the expansion body 10 fills the space remaining above the surface 19 of the support plate 17 (including the separating layer 29) and the surfaces 18 of the basic structures 13 between the end faces 11 of the first track structure 4.1 and the second track structure 4.2. It is cast on site in situ from a polymer-based casting compound, namely in three separate layers 31, 32 and 33, each about 2 cm thick.
- PMMA is used as the base polymer for all three layers 31, 32 and 33.
- the PMMA-based potting compounds of the uppermost expansion body layer 33, which forms the driveable surface 18 of the bridging structure 9, and the two lower expansion body layers 31 and 32 differ from one another in that they contain different additives Z.
- the aggregate Z of the casting compound of the uppermost expansion body layer 33 includes harder fillers than the aggregate of the casting compound of the deeper expansion body layers 31 and 32, in that the fillers in the uppermost expansion body layer 33 hard grain (e.g. corundum) in the However, the two deeper expansion body layers 31 and 32 have EPDM granules and/or rubber granules.
- the uppermost layer 33 of the expansion body 10 consists of about 98% by weight of the PMMA-based polymer resin and hard grain (in total), the weight ratio between hard grain and the PMMA-based polymer resin being about 0.85; the catalyst reactive with the polymer resin forms another component.
- the two underlying layers 31 and 32 of the expansion body 10 are in contrast to each other about 98% by weight of the PMMA-based polymer resin and the EPDM or rubber granules (in total), the weight ratio between EPDM/rubber granules and the PMMA-based polymer resin being about 0.25.
- the catalyst that is reactive with the PMMA forms a further component.
- the two basic structures 13 each have an adhesive surface 34 for the expansion body 10 that extends essentially parallel to the working direction A of the expansion joint 7 .
- These adhesive surfaces 34 are formed by the surfaces 18 of the raised sections 15 of the base structures 13. It is also important that the casting compound of the bottom layer 31 of the expansion body 10 fills the space between the angle perforated strips 23, d. H. their respective horizontal leg 25, and the associated adhesive surface 34 fills as well as possible.
- the angle perforated strips 23 can contribute to this if the angled perforated strips 23 are pressed into the still fresh casting compound immediately after the bottom layer 31 of the expansion body has been cast - or at least the lateral corner areas E have been filled with appropriate casting compound - and attached to the previously set anchors using the nuts 35 22 are fixed. Furthermore, it is relevant for the long-term good edge-side fixation of the expansion body 10 that the casting compound passes through the openings 24 and 28 of the angled perforated strips 23, which counteracts detachment phenomena.
- the spacer plates 26 and the angle perforated strips 23 are dimensioned and designed so that the top of the horizontal leg 25 of the angle perforated strips 23 a level of about 20mm and the upper edges 36 of the vertical legs 27 of the angled perforated strips 23 are about 40mm above the adhesive surfaces 34.
- the upper side of the horizontal legs 25 of the angled perforated strips 23 and the upper edges 36 of the vertical legs 27 of the angled perforated strips 23 are each suitable as a support for pulling off the bottom layer 31 or the middle layer 32 of the expansion body 10.
- the support plate 17' is not mounted in a floating manner. Rather, it is fixed on one side—here on the first partial structure 2.1′—by being firmly connected to the basic structure 13.1′ and the substructure 3.1 of the first partial structure by means of the screws 37 .
- the entire working movement of the bridging structure 9' is thus compensated for by the movement of the support plate 17' with respect to the second partial structure 2.2.
- the gap 20' and the filling strip 21' made of highly compressible material accommodated therein are correspondingly made wider—in the working direction A.
- the seal 6' protrudes under the first track structure 4.1 and extends a little way under the basic structure 13.1' of the first partial structure 2.1'.
- the basic structure 13.1′ of the first partial structure 2.1′ has, compared to the first exemplary embodiment, a greater extension in the working direction A and includes a section 38 with a surface 39 that can be driven on—on the same level as the trafficable surfaces 5 of the two roadway structures 4.1 and 4.2
- Basic structures 13.1′ and 13.2′ are additionally fixed to the associated substructure 3.1 or 3.2 via anchors 40, illustrated here only by means of the basic structure 13.2′.
- the third exemplary embodiment shown in FIGS. 3 and 4 has the special feature that here the support plate 17" is divided into three parts. It comprises a first edge section 41, which is connected to the basic structure 13.1" and the substructure 3.1 "of the first partial structure 2.1" is firmly connected, and a second edge section 43, which is firmly connected in a corresponding manner by means of screws to the basic structure 13.2" and the substructure 3.2" of the second partial structure 2.2". Between the first edge section 41 and the second edge section 43 is (freely floating) the third part of the support plate 17", namely a free support plate section 44 is accommodated.
- the two on either side of the free support plate section 44 between this and the adjacent edge section 41 or 43 existing gaps 45 are not continuous in a straight line, but rather zigzag-shaped.
- the (trapezoidal) mutual projections and recesses of the three parts of the support plate 17" are so long (in the working direction A) that the free support plate section 44 and the two fixed edge sections 41 and 43 in the area of two mutually corresponding teeth 46 - while maintaining of said zigzag column 45 - interlock.
- the support plate can also be made in two parts (divided asymmetrically), each of the two support plate sections being fixed to one of the two partial structures;
- the gap between the two support plate sections, which is offset from the expansion joint, can be continuous in a straight line or - preferably - in the sense of the third exemplary embodiment above zigzag-shaped (e.g. with wavy, trapezoidal, triangular or similar interlocking teeth).
- the uppermost of the layers of the expansion body is preferably cast in one piece over the entire length of the expansion joint.
