CLASS INTERNATIONAL SWEDISH E 04 g17 / 06 37 e: 13/04 PATENT AND REGISTRATION AGENCY Ans. 10 993/1962 was received on 15/10 1962, laid down on 9/8 196 T MYHRE, MYRLAND-SANDNES, AND B HERTVI, STAVANGER, NORWAY Concrete mold fillers in-distance and as a challenge with a larger diameter of a central portion than of duck portions, which protrude from the farm parts and the outer ends of which are provided with riled heads, coupled with sperm fittings, stop means being arranged on the holder to lie against the surface of the mold. , in which the holder is inserted into a sleeve, the length of which is substantially equal to the middle portion and which forms a sliding guide for the holder during its extraction from the heton.

Det fir kant att anvanda en formhallare av ovart angivet slag, forsedd med fasts stoppbrickor, anbragta vid andarna av hallarens mitt-del med stiirre diameter. It is possible to use a mold holder of the type indicated above, provided with fixed stop washers, arranged at the ends of the middle part of the holder with a larger diameter.

Efter att betongen är tillrackligt hardad avlagsnas formen, och hallarens mittparti kvarstar fastgjutet i betongen. Hallarens andpartier utanfar stoppbriekorna hrytas av eller klippas bort ach utgara darefter skrot, som ofta endast kasseras. After the concrete has hardened sufficiently, the shape is deformed, and the middle part of the holder remains cast in the concrete. The duck parts of the hall outside the stop brakes are scraped off or cut off and then scrapped, which is often only discarded.

Den i det ovanstaende beskrivna formhallaren ar ratt oekonomisk och tidskravande vid anvandningen. Hallaren kan salunda endast anvandas en enda gang, och avlagsnandet at andpartierna raedfOr ett forhallandevis stort extraarbete. Dessutom komma de i betongen kvarstaende andytarna av mittpartiet att naedfora rostbildning, som skadar utseendet av betongens ytterytor. The mold holder described above is quite economical and time-consuming to use. The hall can thus only be used once, and the removal of the duck parts necessitates a relatively large extra work. In addition, the end faces of the middle part remaining in the concrete will cause rust formation, which damages the appearance of the outer surfaces of the concrete.

Det fir dessutom kant att anordna en. hylsa pa en stang, som har jamn diameter utefter hela sin langd, sâ att pa stangen tradda briekor maste stbda mot hylsan. Detta forutsatter emellertid, att hylsan Mir dimensioneras med tillräeklig stabilitet och hillfasthet for att kunna upptaga det av brickorna utdvade axiella tryeket. It also has an edge to arrange one. sleeve on a rod, which has an even diameter along its entire length, so that brakes threaded on the rod must rest against the sleeve. However, this presupposes that the sleeve Mir is dimensioned with sufficient stability and shelf strength to be able to absorb the axial pressure exerted by the washers.

Uppfinningen avser att astadkomma en he tongformhallare, vid vilken de i det ovansta; ende anforda olagenheterna Are eliminerade. The invention aims to provide a hong mold holder, in which they in the above; only claim the illegalities Are eliminated.

Detta uppnas vid betorigformhallaren enligt uppfinningen genom att stopporganen Are utformade scan tunna brickar med singernel:. lan parallella plana andytor och med ett hal, vars diameter dr sadan, att briekorna knnn tradas pa andpartierna till anliggning mot mittpartiet, sa att brickorna efter betongen hardande aro horttagbara fran hMla.ren. This is achieved at the hopper mold holder according to the invention by the stop means Are designed scan thin trays with singernel: parallel flat end faces and with a hall, the diameter of which is such that the bricks can be threaded on the duck portions to abut against the middle part, so that the trays hardening after the concrete are removable from the hMla.ren.

Hylsan kan med fordel vara utfOrd av plast eller av nagot snnat lampligt material ac4 vara fastgjuten i betongen, sA att hallaren kan; dras ut ur betongen och anvandas pa nytt. The sleeve can advantageously be made of plastic or of some other suitable material, and can be cast in the concrete, so that the holder can; pulled out of the concrete and reused.

Den fastgjutna plasthylsan kan, nar halls. ren avlagsnats, am sa onskas, likaledes tas bort ur betongen, varefter det kvarsthende ha.; let kan fyllas igen med betongblandning,lnen fiven oin man later plasthylsan. sta kvar i betongen uppnas den fOrdelen i farhallande till kanda formhallare, att betongens ytterytai icke forstoras genom rostbildning. The molded plastic sleeve can be held. pure avlagsnats, am sa onskas, likewise removed from the concrete, after which the remaining ha .; the lid can be filled again with concrete mixture, lnen fiven oin you leave the plastic sleeve. Remaining in the concrete, the advantage is achieved in conveying to well-known mold holders that the outer surface of the concrete is not enlarged by rust formation.

Uppfimiingen forklaras narmare i samband med bifogade ritning, som visar ett utforingsexempel pa en formhallare enligt uppfinningen. Fig. 1 visar formhallaren, sedd fran sidan och monterad i formen med en glidstyrningshylsa i mitten i sektion. Fig. 2 dr en sektion utefter linjen Hall i fig. 1. Fig. 3 ar en sek- tion utefter linj eni fig. 1. The invention is explained in more detail in connection with the accompanying drawing, which shows an embodiment of a mold holder according to the invention. Fig. 1 shows the mold holder, seen from the side and mounted in the mold with a slide guide sleeve in the middle in section. Fig. 2 is a section along the line Hall in Fig. 1. Fig. 3 is a section along the line in Fig. 1.

Formhallaren bestar pa kfint salt av en stang 3, vars mittparti 1, som kommer att ligga mellan formbraden F, har en na' got star-re diameter an formhallarens andpartier. Detta kan Ian uppnas genom att fastsvetsa ett ror pa hallaren, vilket rOr bar en innerdiameter, sam svarar mot stangens 3 diameter. Hallarens klenare andpartier 3 Are forsedda med andhuvuden, som foras in. i vanliga spannbeslag (joke visade), vilka placeras vid utsidan av formens yttre stator eller liggare (icke visade).-Innanfor findhuvudena dr hal- 2 laren utformad med partier 4 med mindre diameter oeh tvà sinsemellan parallella ytor, bildande angreppsytor for t. ex. en skruvnyc- kelatt vrida hallaren. The mold holder consists of fine salt of a rod 3, the middle portion 1, which will lie between the mold plate F, has a slightly larger diameter than the duck portions of the mold holder. This can be achieved by welding a tube on the holder, which tube had an inner diameter corresponding to the diameter of the rod 3. Hallaren's smaller duck parts 3 Are provided with duck heads, which are inserted. in ordinary bucket fittings (joke shown), which are placed on the outside of the mold's outer stator or beams (not shown) .- Inside the find heads, the holder 2 is formed with portions 4 of smaller diameter and two mutually parallel surfaces, forming attack surfaces for e.g. . a wrench turn the holder.

Pd det kraftigaste mittpartiet 1 ar enligt uppfinningen patradd en slang eller hylsa av plast eller av nagot annat lampligt material, vilken slang eller hylsa är avsedd att fastgjutas i betongen och vilken harefter utgor en glidstyrning fOr hallaren 3, 1, nar denna skall dras ut eller aids ut ur den hardade betongen. Stoppbrickor 5, utgorande anslag for innersidan av formbraden F, aro lost patradda pa hallarens andpartier 3 och kunna forskjutas utefter desanuna. Stoppbriekorna ha ett uttag 6, som stracker sig frAn brickans cirkulam mittOppning till periferin, sa att briekorna kunna tagas bort fran och sattas upp pd hallaren vid det klenare partiet 4. Bred-den av uttaget 6 vid brickans centrala Oppning Sr nagot stone an bredden av det klenare partiet 4, men mindre an stan,gens 3 diameter. According to the invention, a hose or sleeve of plastic or of some other suitable material is threaded onto the strongest central portion 1, which hose or sleeve is intended to be cast in the concrete and which then forms a sliding guide for the holder 3, 1, when it is to be pulled out or aids out of the hardened concrete. Stop washers 5, forming stops for the inside of the mold plate F, are loosely patterned on the end portions 3 of the holder and can be displaced along the same. The stop briquettes have a socket 6, which extends from the center of the tray to the periphery, so that the briquettes can be removed from and placed on the holder at the smaller portion 4. The width of the socket 6 at the central opening of the tray is slightly stone the width of the smaller part 4, but smaller than the diameter of the gen 3.

Brickorna 5 kunna eventuellt utelanmas genom att mittpartiet 1 i detta fall dimensioneras med tiliraeklig diameter RI ratt bilda en tillrackligt star anliggningsyta for innersidan av formbraden F. Dessa anligoningsytor forstoras in aven med hjalp av plastroret 2, och nar detta gores tillrackligt grovt, kunna dess Andytor ensamma ersitta stoppbrickorna 5. Det dr emellertid i de fiesta fall ldmpligt att =van& stoppbriekor. The washers 5 can optionally be omitted by the middle portion 1 in this case being dimensioned with a sufficient diameter R1 to form a sufficiently rigid abutment surface for the inside of the mold plate F. These abutment surfaces are also enlarged by means of the plastic tube 2, and when this is made sufficiently coarse, its replace the stop washers alone 5. However, in most cases it is fadmpligt to = van & stop washers.
