Description

PL 71 791 Y1 2 Opis wzoru Przedmiotem wzoru jest stanowisko do wykonania cienkosciennych plyt betonowych zbrojonych siatkami tekstylnymi. „Teksbet” (ang. „Textile Reinforced Concrete”) jest nowoczesnym materialem budowlanym, w którym, jako zbrojenie do betonu, wykorzystuje sie alternatywne, w stosunku do klasycznego zbroje- nia ze stali, siatki tekstylne. Po zastapieniu tradycyjnych siatek ze stali siatkami wykonanymi z ciaglych wlókien niemetalicz- nych (np. szklanych lub weglowych) mozliwe jest znaczne zmniejszenie grubosci elementów z uwagi na podwyzszone parametry wytrzymalosciowe w porównaniu do stali, jak i ze wzgledu na znaczne zmniejszenie otuliny zbrojenia wymaganej z uwagi na trwalosc. Cienkoscienne plyty zelbetowe sa przede wszystkim wykonywane w zakladach prefabrykacji, gdzie obowiazuja szczególne rygory kontroli jakosci. Minimalna grubosc tych plyt jest nadal ograniczona wymaganiami normowymi, które w wypadku Eurokodu 2 ograniczaja sie do wartosci minimalnego otulenia. „ Teksbet” jest badany i eksperymentalnie stosowany w rozwiazaniach technicznych od niespelna lat. Zaawansowane prace badawcze tego materialu sa prowadzone w Europie – w Niemczech, w dwóch wspólpracujacych osrodkach: Rheinisch-Westfälische Technische Hochschule (RWTH) Aa- chen (W. Brameshuber, J. Hegger et al. Serielle Stückfertigung von Bauteilen aus textilbewehrtem Beton. Beton- und Stahlbetonbau, vol. 103, No. 2, Jan 2008, str. 64–72) oraz Technische Universität (TU) Dresden (M. Curbach et al. Eigenschaften und Anwendung von Textilbeton. Beton- und Stahlbet- onbau, vol. 104, No. 1, Jan 2009, str. 9–16). W RWTH Aaachen szczególna uwage poswieca sie badaniom nowych elementów konstrukcyj- nych. Tymczasem badania prowadzone w TU Dresden sa ukierunkowane na wykorzystanie „teksbetu” do wzmacniania i modernizacji istniejacych konstrukcji. Badania teksbetu prowadzono równiez (na mniejsza skale) w Belgii (Vrije Universiteit Brussel – H. Cuypers et al., Durability of glass fibre reinforced composites experimental methods and results.

Textile Reinforced Structures. Proceedings of the 2 nd Colloquium on Tex- tile Reinforced Structures (CTRS2), Editor: Curbach M., Dresden 2003, str. 145–160), w Izraelu (Ben Gurion University – A. Peled, Effect of matrix modification on durability of glass fiber reinforced cement composites. Materials and Structures, vol. 38, No. 2, March 2005, str. 163–171), w Grecji (University of Patras – G. C. Papanicolaou et al., Textile Reinforced Concrete (TRC) for precast Stay-in-Place form- work elements. Tailor made concrete structures.

American Concrete Insti- tute, Special Publication, vol. 244, No. 8, May 2007, str. 125–140). W Polsce, „teksbet” jest przedmiotem badan A. Ajdukiewicza, B. Kotali i M. Weglorza. Pierwsze wyniki pilotazowych badan zostaly przedstawione przez A. Ajdukiewicza na Sympozjum fib w Londynie, w roku 2009 (A.

"Teksbet" ("Textile Reinforced Concrete") is a modern construction material in which, as reinforcement for concrete, textile mesh is used as an alternative to the classic steel reinforcement. After replacing traditional steel meshes with nets made of continuous non-metallic fibers (e.g. glass or carbon), it is possible to significantly reduce the thickness of the elements due to the increased strength parameters compared to steel and due to the significant reduction of the reinforcement cover required for for durability. Thin-walled reinforced concrete panels are primarily made in prefabrication plants, where special quality control requirements apply. The minimum thickness of these boards is still limited by the standard requirements, which in the case of Eurocode 2 are limited to the minimum cover value. "Teksbet" has been tested and experimentally used in technical solutions for less than years. Advanced research on this material is carried out in Europe - in Germany, in two cooperating centers: Rheinisch-Westfälische Technische Hochschule (RWTH) Aachen (W. Brameshuber, J. Hegger et al. Serielle Stückfertigung von Bauteilen aus textilbewehrtem Concrete. Concrete- und Stahlbetonbau, vol. 103, No. 2, Jan 2008, pp. 64-72) and Technische Universität (TU) Dresden (M. Curbach et al. Eigenschaften und Anwendung von Textilbeton. Beton- und Stahlbet- onbau, vol. 104 , No. 1, Jan 2009, pp. 9-16). At RWTH Aaachen, special attention is paid to the testing of new structural elements. Meanwhile, research at TU Dresden is focused on using "texbet" to strengthen and modernize existing structures. Texbet studies were also carried out (on a smaller scale) in Belgium (Vrije Universiteit Brussel - H. Cuypers et al., Durability of glass fiber reinforced composites experimental methods and results. Composites Part A: Applied Science and Manufacturing, vol. 37, No. 2 , Feb 2006, pp. 207-215), in Great Britain (University of Warwick - P. Purnell, Advances in Modeling GRC Durabillity. Textile Reinforced Structures. Proceedings of the 2 nd Colloquium on Tex- tile Reinforced Structures (CTRS2), Editor : Curbach M., Dresden 2003, pp. 145–160), in Israel (Ben Gurion University - A. Peled, Effect of matrix modification on durability of glass fiber reinforced cement composites. Materials and Structures, vol. 38, No. 2 , March 2005, pp. 163-171), in Greece (University of Patras - GC Papanicolaou et al., Textile Reinforced Concrete (TRC) for precast Stay-in-Place form- work elements.

American Concrete Institute, Special Publication, vol. 244, No. 8, May 2007, pp. 125–140). In Poland, "texbet" is the subject of research by A. Ajdukiewicz, B. Kotala and M. Weglorz. The first results of the pilot study were presented by A. Ajdukiewicz at the fib Symposium in London in 2009 (A. Ajdukiewicz, Tests on Thin-Walled Concrete Members Reinforced With Non-metallic Fabrics. Proceedings of the 11 th Annual International FIB Symposium: CONCRETE: 21st Century Superhero - Building a Sustainable Future. 2009 London. Volume of Abstracts and CD. Session C3 - Materials, 8p).

Textile nets play the role of reinforcement of concrete slabs and consist of strands. The weaves consist of bundles of non-metallic synthetic fibers. Textile nets are flaccid and very often only intertwined, without stiffening in the knots, which necessitates additional stabilization of the textile nets in the mold, hence the need for a special stand to stiffen the nets during concreting. The problem of mesh stabilization is solved by the presented utility formula. The essence of the pattern is a stand for making thin-walled concrete slabs reinforced with textile meshes, having a tension structure, characterized by the fact that the active anchorage is made of a steel bottom flat bar and a steel top flat bar with steel tensioning cables, which active anchorage is equipped with hook dynamometers and hook dynamometers. Roman and threaded rods, while the passive anchor is made of a steel bottom flat bar and a steel top flat bar connected with screws. The mesh of the textile reinforcement is stabilized in the active anchorage by epoxy glue. The steel bottom flat bar and the top steel flat bar are connected by clamping bolts. The mesh of the textile reinforcement is stabilized in the passive anchorage by epoxy glue and screws. The stand according to the pattern provides for the production of concrete slabs reinforced with textile meshes at the same time, from one batch and without the need to stage the concrete mix laying operation. The stand is used to make thin-walled concrete slabs reinforced with textile meshes with the required minimum cover. The object of the utility model is shown in the drawing, in which Fig. 1 shows a top view of the station, Fig. 2 - side view of the station, Fig. 3 shows the detail "A", ie active anchorage, Fig. 4 - detail "B" ", Ie passive anchorage, fig. 5 - concrete form" C ". According to the pattern, the stand includes the bottom plate of the MDF form 1, the lower part of the wall of the plywood form 2 and the upper part of the wall of the plywood form 3. The structure of the tension consists of active anchorage A and passive anchorage B. Active anchorage A consists of a steel lower flat bar 5, connected to the upper steel flat bar 7 by means of clamping screws 8. The steel tensioning cables 9 transmit evenly the tension to the lower 5 and upper steel flat bars 7 of the active anchorage A. Hook dynamometers 10 enable the control of the tension force. The threaded rods 11 play the role of a link between the turnbuckle 12 and a hook dynamometer 10 and the steel tensioning lines 9, and the turnbuckles 12, by rotating them about their axis, perform the tension. I-section 14 is a fastening element for threaded rods 11. To I-section 14 are connected by welding: the end plate of the fixed support 13 and the ribs 15. The threaded rods 11 are attached to the ribs 15. The ribs 15 reinforce the I-section 14. The plate The front fixed support 13 is used to fasten the I-section 14 to the supporting steel structure comprising the C-section 20, I-section 21 and the plate 22. The passive anchorage B consists of the lower flat steel 16 of the passive anchor B and the steel upper flat member 17 of the passive anchorage B connected with the bottom screws 18. Plates MDF 1 molds are connected to MDF 23 with screws 19. MDF 23 serves as a base on which the concrete mold is placed C. Textile reinforcement mesh 4 is glued into active A and passive B anchors on epoxy adhesive 6. To stabilize the mesh of the textile reinforcement 4 in the form for concrete C, on one side the mesh of the textile reinforcement 4 is fixed permanently through the lap Passive opening B for a steel bottom flat bar 16 and a steel top flat bar 17. On the opposite side, it is possible to stretch the mesh of the textile reinforcement 4, regulated by an active anchorage A through a steel bottom flat bar 5, a steel top flat bar 7, connected with four evenly spaced steel tension cables 9 through a hook dynamometer 10, threaded rods 11 and turnbuckles 12 for the steel structure. The stand is supported on a supporting steel structure comprising a C-profile 20, an I-section 21 and a sheet 22. The tension is carried out until the mesh of the textile reinforcement 4 is straightened, but the force of 0.5 kN / m should not be exceeded. The stand is intended for making concrete slabs reinforced with textile meshes placed in the form of concrete C in such a way that the strands of the mesh of textile reinforcement 4 are arranged orthogonally with respect to each other and perpendicular to the side walls of the form into concrete C. The stand is used to make the slab rectangular, with dimensions of 1.0 m? 3.6 m and a thickness of 40 mm. The mesh of textile reinforcement 4 is stabilized in ¼ of the concrete slab cross-section height, i.e. at a height of 10 mm from the bottom slab of the concrete form C.
