Pierwszenstwo: Zgloszenie ogloszono: 30.05.1973 Opis patentowy opublikowano: 31.12.1975 82297 KI. 37e,15/04 MKP* E04g 15/04 CZYTELNIA ^ca Patentowe go Twórcywynalazku: Ireneusz Polak, Bogdan Krysztof, Jan Kedzierski Uprawniony z patentu tymczasowego: Opolskie Przedsiebiorstwo Budownictwa Przemyslowego Nr 2, .' Opole (Polska) Oslona studzienek na sruby kotwiace w elementach betonowych zwlaszcza w fundamentach pod maszyny Przedmiotem wynalazku jest oslona studzienek na sruby kotwiace w elementach betonowych zwlaszcza w fundamentach pod maszyny. Oslona zabezpiecza studzienke przed naplywem mieszaniny betonowej podczas wykonywania elementu betonowego kotwiacego oraz nadaje postac studzience.W praktyce znane sa oslony studzienek na sruby kotwiace, wykonywane w postaci skrzynek drewnianych, które po stwardnieniu betonu usuwane sa ze studzienek. Znane sa równiez oslony w postaci tulei z blach stalowych, których scianki posiadaja styki równolegle do osi podluznej oslony.Wada oslon drewnianych jest pracochlonny montaz w warunkach budowy wymagajacy wykonania dodatkowo kolnierzy stalowych na plytach kotwiacych, sluzacych do umocowania oslony. Ponadto podczas usuwania ze studzienek elementów drewnianych oslony zostaje naruszana struktura betonu przyleglego do oslony. Wada oslon pelnosciennych z blach stalowych jest duze zuzycie stali na ich wykonanie, a znaczny ich ciezar ogranicza zakres stosowania tych oslon.Celem wynalazku jest usuniecie powyzszych wad i niedogodnosci, a zadaniem technicznym opracowanie oslony studzienek na sruby kotwiace o nieograniczonym zakresie stosowania, gwarantujacej pelna wartosc uzytkowa kotwionych elementów, lekkiej, dogodnej w stosowaniu, umozliwiajacej uzyskanie oszczednosci materialowych. Zgodnie z p/zedmiotem wynalazku postawione zadanie techniczne zostalo rozwiazane poparte szeregiem doswiadczen w zastosowaniu praktycznym, przez opracowanie oslony skladajacej sie z podstawy i scianki oslony uksztaltowanej korzystnie z pasa blachy stalowej cienkiej, zwinietego spiralnie po obwodzie tworzacej walca o wymiarach studzienki. Utworzony w sciance oslony spiralny styk pasa blachy stalowej jest szczelny, nie przepuszcza mieszaniny betonowej. Scianke oslony stanowi odcinek rury stosowanej na kanaly wentylacyjne polaczony z urzadzeniem kotwiacym przez spawanie.Zaleta rozwiazania oslony wedlug wynalazku jest to, ze spiralny styk pasa blachy stalowej usztywnia scianke oslony, powoduje korzystny efekt przyczepnosci oslony do betonu, przez co zwieksza pewnosc zamocowania srub kotwiacych. Ponadto oslona ta jest lekka, dogodna w stosowaniu, umozliwia uzyskanie oszczednosci materialowych.2 82 297 Przedmiot wynalazku przedstawiony jest w przykladzie wykonania na rysunku, na którym fig. 1 przedsta¬ wia oslone w widoku z przodu, a fig. 2 — przedstawia oslone w przekroju wzdluz linii A—A, na fig. 1 z uwidoczniona puszka kotwiaca. Jak uwidoczniono na fig. 1 i 2 oslona sklada sie ze s'cianki oslony 1 stanowiacej odcinek rury stosowanej na kanaly wentylacyjne, uksztaltowanej z pasa blachy stalowej cienkiej, zwinietego spiralnie po obwodzie tworzacej walca o wymiarach studzienki polaczonego na rabek pojedynczy w styku 2, oraz z postawy oslony 3 stanowiacej puszke kotwiaca. Oba elementy oslony polaczone sa miedzy soba przez spawanie. Oslone osadza sie w miejscu przeznaczenia w wykonywanym elemencie betonowym 4. PL PLPriority: Application announced: May 30, 1973 Patent description was published: December 31, 1975 82297 KI. 37e, 15/04 MKP * E04g 15/04 READING ROOM The authors of the invention: Ireneusz Polak, Bogdan Krysztof, Jan Kedzierski Authorized by a temporary patent: Opolskie Przedsiebiorstwo Budownictwa Przemysłowego No. 2,. ' Opole (Poland) Cover of manholes for anchor bolts in concrete elements, especially in machine foundations. The subject of the invention is the cover of manholes for anchor bolts in concrete elements, especially in machine foundations. The cover protects the well against the influx of concrete mixture during the construction of the anchoring concrete element and gives the shape of a well. In practice, it is known to cover the wells for anchor bolts, made in the form of wooden boxes, which are removed from the wells after hardening of the concrete. There are also shields in the form of steel sheet sleeves, the walls of which have joints parallel to the longitudinal axis of the shield. The disadvantage of wooden shields is the time-consuming assembly under construction conditions, requiring additional steel flanges on anchoring plates, used to fasten the shield. Moreover, when removing wooden elements of the cover from the wells, the structure of the concrete adjacent to the cover is disturbed. The disadvantage of full-body casings made of steel sheets is the high steel consumption for their production, and their considerable weight limits the scope of application of these casings. The purpose of the invention is to remove the above-mentioned drawbacks and inconveniences, and the technical task is to develop an unlimited scope of use for anchor wells, guaranteeing their full value. usability of the anchored elements, light, easy to use, allowing for material savings. According to the subject matter of the invention, the technical task posed has been solved, supported by a series of practical experience, by developing a cover consisting of a base and a wall of a cover, preferably formed of a strip of steel sheet, coiled in a spiral around the circumference forming a cylinder with the dimensions of a well. The spiral joint of the steel sheet strip formed in the wall is tight and does not let the concrete mixture pass through. The wall of the shield is a section of the pipe used for ventilation ducts connected to the anchoring device by welding. The advantage of the shield solution according to the invention is that the helical contact of the steel sheet strip stiffens the shield wall, results in a favorable adhesion effect of the shield to concrete, which increases the security of anchoring bolts. Moreover, this cover is light, easy to use, and allows for material savings.2 82 297 The subject of the invention is shown in an example of embodiment in the drawing, in which Fig. 1 shows the cover in a front view, and Fig. 2 - shows the cover in section along line A-A, in Fig. 1 the anchor box is shown. As shown in Figs. 1 and 2, the casing consists of a wall of the casing 1 constituting a section of a pipe used for ventilation ducts, formed from a strip of thin steel sheet, coiled in a spiral around the circumference forming a cylinder with the dimensions of a well connected to a single rebate at the joint 2, and from the position of the cover 3 constituting the anchoring box. Both elements of the shield are connected with each other by welding. The shield is embedded in the concrete element to be constructed at its destination 4. PL PL
