Opis patentowy opublikowano: 15.10.1977 87367 MKP E21d 7/02 Int. Cl2. E21D7/02 CZYTELNIA Urzedu Patentowego Msnej Izeczipospaliuj Lunwej2 87 367 Dla zabudowy czesci rurkowej 2 kotwi 1 wykorzystuje sie znane, odpowiednio przystosowane, odeskowa¬ nie stalowe 4. Przystosowanie odeskowania 4 sprowadza sie do wykonania szeregu otworów 5 rozmieszczonych stosownie do potrzeb wynikajacych z odstepów miedzy dzwigarami zbrojenia w szybie oraz do uzupelnienia konstrukcji odeskowania 4 lancuchami stabilizujacymi 7.Patent description was published: October 15, 1977 87367 MKP E21d 7/02 Int. Cl2. E21D7 / 02 READING ROOM The Patent Office Msnej Izeczipaliuj Lunwej2 87 367 For the installation of the tubular part 2 of the bolt 1, known suitably adapted planking is used not steel 4. Adaptation of the formwork 4 comes down to making a series of holes 5 arranged according to the needs resulting from the gaps between the girders of the reinforcement in the shaft and to the supplement deck structure with 4 stabilizing chains 7.
Czesc rurkowa 2 kotwi 1 wprowadza sie do przestrzeni poza odeskowaniem 4 poprzez otwory 5 mocujac ja, na czas wznoszenia obudowy betonowej 3, do odeskowania srubami 6. Lancuchy stabilizujace 7 o stalej dlugosci przymocowane rozlacznie z jednej strony do konstrukcji odeskowania 4, a z drugiej do kotwi rurkowej 1 zabudowanej w obudowie szybu 3, pozwalaja na ustawienie odeskowania dokladnie co do zadanego kierunku i wysokosci.The tubular part 2 of the bolt 1 is inserted into the space outside the formwork 4 through the fixing holes 5 I, for the time of erecting the concrete casing 3, for boarding with screws 6. Stabilizing chains 7 with fixed lengths detachably attached on one side to the decking structure 4 and on the other to the tubular anchor 1, built in the shaft casing 3, allow the decking to be positioned exactly in the given direction and altitude.
Cykl pracy przy betonowaniu obudowy szybu z równoczesnym zabudowaniem rurek kotwi 1, rozpoczyna sie od opuszczenia odeskowania 4 w nowe polozenie. W tym celu odczepia sie lancuchy stabilizujace 7 od obudowy szybu 3, opuszcza odeskowanie 4 o taka odleglosc, która pozwoli na odsloniecie kolejnych miejsc mocowania lancuchów stabilizujacych. Przytwierdza ponownie lancuchy 7 do obudowy w nowych miejscach kotwienia, a nastepnie dalej opuszcza odeskowanie, az do naprezenia sie wszystkich lancuchów stabilizujacych.The work cycle for concreting the shaft casing with the simultaneous installation of the anchor tubes 1 begins since the deck 4 has been lowered into a new position. For this purpose, the stabilizing chains 7 are detached from the shaft casing 3 leaves the formwork 4 by such a distance that will allow for the exposure of subsequent places fixing stabilizing chains. Reattaches chains 7 to the housing in new places the anchors and then further leaves the decking until all stabilizing chains are taut.
Zaklada sie gwintowane rurki 2 kotwi 1 mocujac je do odeskowania 4, srubami 6. Otwory 5, które wdanym odcinku obudowy szybu nie beda wykorzystane dla zabudowy w nich rurek 2 kotwi 1 zostana zakryte przez wkrecenie do nich korków. Potem betonuje sie obudowe calego odcinka szybu. Po zwiazaniu betonu w obudowie przystepuje sie do wykrecania srub 6 i po zglebieniu kolejnego odcinka szybu mozna przystapic do kolejnego opuszczania odeskowania 4 w nowe polozenie. W ten sposób rurki 2 kotwi 1 pozostana w obudowie betonowej 3 szybu i sluza do umocowania konstrukcji zbrojenia szybowego do tej obudowy.Threaded tubes 2 anchors 1 are fitted to the formwork 4 with screws 6. Holes 5, which are section of the shaft casing will not be used for the installation of pipes 2, anchors 1 will be covered by screwing the plugs into them. Then the casing of the entire shaft section is concreted. After the concrete has set in the housing, the screws 6 are removed and after the next section of the shaft has been deepened, it is possible to subsequent lowering of the formwork 4 to its new position. Thereby, the tubes 2 of the bolt 1 will remain in the housing concrete 3 of the shaft and is used to attach the shaft reinforcement structure to this housing.
Istnienie rurek kotwi w betonie, w czasie wiazania betonu, zapewnia bardzo pewne i trwale polaczenie rurki z betonem. Przyczepnosc rurki kotwi do betonu mozna maksymalnie zwiekszyc przez pokrycie powierz¬ chni zewnetrznej rurki karbami lub nacieciami. Powierzchnia przylegania rurki do obudowy betonowej jest znacznie wieksza niz przy kotwiach typu klinowego przez co naciski jednostkowe na obudowe sa znacznie mniejsze, a tym samym istnieje mniejsza nr ozliwosc obluzowania tych kotwi. Kotew rurkowa jest bardziej odporna na korozje niz kotwie dotychczas stosowane, gdyz jest ona calkowicie otoczona z zewnatrz przez beton, a od wewnatrz zabezpieczona wazelina techniczna. Uzycie tych kotwi umozliwi ewentualna wymiane srub kotwi na dluzsze w przypadku zniszczenia gwintu i zalozonych srub, gdyz rurki kotwi posiadaja dosc znaczna dlugosc i sa na calej swej dlugosci nagwintowane. Daje to mozliwosc kilkakrotnej wymiany srub kotwi na coraz to dluzsze w przypadku ich zniszczenia (korozja lub mechaniczne uszkodzenia). Przyspiesza prace zwiazane ze zbrojeniem szybu ograniczajac je jedynie do czynnosci montazowych, eliminujac wiercenie otworów pod kotwie, wypelnianie zaprawa i osadzanie kotwi.The existence of the anchor tubes in the concrete during the setting of the concrete ensures a very secure and permanent connection pipes with concrete. The adhesion of the anchor pipe to concrete can be maximized by covering the surface cuts the outer tube with notches or cuts. The contact surface of the tube to the concrete housing is much greater than with wedge-type anchors, therefore the unit pressure on the casing is significantly smaller, and therefore there is less chance of loosening these bolts. The tubular anchor is more resistant to corrosion than previously used anchors, as it is completely surrounded from the outside by concrete, and from the inside protected with technical petroleum jelly. The use of these bolts will enable the possible replacement of the bolts longer in the case of damage to the thread and inserted screws, as the anchor tubes are quite long and are threaded all their length. This makes it possible to replace the bolts several times with more longer in case of their destruction (corrosion or mechanical damage). Speeds up work related to shaft reinforcement, limiting them only to assembly operations, eliminating drilling holes under the anchor, mortar filling and anchoring.
Rozwiazanie wedlug wynalazku upraszcza wykonanie kotwi oraz ulatwia konserwacje zbrojenia w czasie eksploatacji szybu.The solution according to the invention simplifies the execution of the bolt and facilitates the maintenance of the reinforcement over time shaft operation.
