Description

Anordning for befestigelse av foringsplater av elastisk, slitesterkt materiale til innsiden av veggen i en betongblandetrommel. Device for attaching lining plates of elastic, wear-resistant material to the inside of the wall in a concrete mixing drum.

Oppfinnelsen vedrorer en anordning for befestigelse av foringsplater av elastisk, slitesterkt materiale til innsiden av veggen i en betongblandetrommel e.l., hvilke plater er festet til metallplater som igjen ved skruebolter er festet til nevnte vegg. The invention relates to a device for attaching lining plates of elastic, wear-resistant material to the inside of the wall in a concrete mixing drum etc., which plates are attached to metal plates which are in turn attached to said wall by means of screw bolts.

Tidligere har slike foringsplater vært festet til innsiden av trommelvegger ved hjelp av skinner eller lister. Disse har da vært anordnet for anlegg mot metallplatenes kanter som har strukket seg et stykke forbi foringsplatenes kanter, slik at der dannes flenser mot hvilke disse klemlister kan ligge an. Mel-lomrommet mellom foringsplatene er så dekket ved en list av fortrinnsvis samme materiale som foringsplatene. Derved fås på hvert skjotsted tb parallelt lopendé skjotlommer. In the past, such lining plates have been attached to the inside of drum walls using rails or strips. These have then been arranged for contact with the edges of the metal plates which have extended a bit past the edges of the lining plates, so that flanges are formed against which these clamping strips can rest. The space between the lining plates is then covered by a strip of preferably the same material as the lining plates. As a result, at each splice point, tb parallel run-end splice pockets are obtained.

Ifolge oppfinnelsen tilveiebringes en anordning for slik be- j ; festigelse, hvorved oppnås at man kun får en skjotsom på hvert skjotested mellom foringsplatene. Dette oppnås ifolge opp- j According to the invention, a device is provided for such a job; fastening, whereby it is achieved that only one joint is obtained at each joint between the lining plates. This is achieved according to opj

finnelsen ved at f oringsplatene er anordning for på skjotestedejne med sine kanter å ligge an mot hverandre butt-i-butt, mens de til foringsplatene festede metallplater er avsluttet tilnærmet en halv boltdiameter fra nevnte kanter, og at det på et passende antall steder, fortrinnsvis to, er anordnet uttagninger i for-j ingsplatenes kanter for klemplater, anordnet på skrueboltene for fastholding av metallplatene, idet boltene er fort gjennom ! herfor tilpassede hull i trommelveggen og gjennom mellom-; rommet mellom metallplatenes kanter. J the invention in that the lining plates are arranged so that their edges lie against each other butt-in-butt on the jointing plates, while the metal plates attached to the lining plates are terminated approximately half the bolt diameter from said edges, and that in a suitable number of places, preferably two, cutouts are arranged in the edges of the front plates for clamping plates, arranged on the screw bolts for holding the metal plates, as the bolts are fast through ! for this, adapted holes in the drum wall and through intermediate; the space between the edges of the metal plates.

i in

Et foretrukket trekk er at klemplatene er forsynt med en kledning svarende til uttagningene, hvilken kledning fortrinnsvis er av samme materiale som foringsplatene. A preferred feature is that the clamping plates are provided with a lining corresponding to the recesses, which lining is preferably of the same material as the lining plates.

Til bedre forståelse av oppfinnelsen skal denne beskrives nærmere under henvisning til et på tegningen vist utforelses-eksempel. Fig. 1 viser sett i plan en skjot mellom to forihgsplater anordnet ifolge oppfinnelsen. For a better understanding of the invention, it will be described in more detail with reference to an embodiment example shown in the drawing. Fig. 1 shows a plan view of a joint between two connecting plates arranged according to the invention.

Fig. 2 viser et snitt efter linjen I-l; og Fig. 2 shows a section along the line I-1; and

Fig. 3 viser et snitt efter linjen II - II. Fig. 3 shows a section along the line II - II.

De sammenstotende foringsplater 1, 1' ligger på skjotstedet, The abutting lining plates 1, 1' lie at the joint,

som det vil sees av fig. 1 og 3, an mot hverandre med kantene i butt-i^butt skjot 4. Metallplatene 2, 2' som er fast for-bundet med foringsplatene 1, 1', er ikke fort helt frem til disses kanter. De er avsluttet på en avstand lik tilnærmet en halv boltdiameter fra foringsplatenes kanter. Derved fås det som det sees av fig. 3, butt-i-butt skjot mellom foringsplatene 1, 1' men et mellomrom 5 mellom metallplatenes kanter. as will be seen from fig. 1 and 3, against each other with the edges in a butt-in-butt joint 4. The metal plates 2, 2', which are firmly connected to the lining plates 1, 1', are not fast all the way to their edges. They are finished at a distance equal to approximately half the bolt diameter from the edges of the lining plates. Thereby, as can be seen from fig. 3, butt-in-butt shot between the lining plates 1, 1' but a space 5 between the edges of the metal plates.

På et hensiktsmessig antall steder langs skjoten, i det viste eksempel to, er det gjort uttagninger 9 i foringsplatenes materiale. Derved vil det på disse steder fremkomme blottlagte partier av metallplatene 2, 2', og disse partier dekkes i storre eller mindre utstrekning av en klemplate 8 som ved en bolt 7, 7' fastskrues til trommelveggen 3. Klemplatene 8 er forsynt med en kledning 6 fortrinnsvis av samme materiale som foringsplatene 1, 1'. Som det fremgår av fig. 1 fås det således ved anordningen ifolge oppfinnelsen kun en enkelt skjotlinje 4 mellom platene 1, 1' samt to innfelte partier 6 av samme materiale som foringsplatene og som dekker over klemplatene 8 som fastholder metallplatene 2, 2<1> og de til disse festede f oringsplater 1, 1'. At an appropriate number of places along the joint, in the example two shown, cutouts 9 have been made in the material of the liner plates. Thereby exposed parts of the metal plates 2, 2' will appear in these places, and these parts are covered to a greater or lesser extent by a clamping plate 8 which is screwed to the drum wall 3 by means of a bolt 7, 7'. The clamping plates 8 are provided with a cladding 6 preferably of the same material as the lining plates 1, 1'. As can be seen from fig. 1, the device according to the invention thus provides only a single joint line 4 between the plates 1, 1' as well as two recessed parts 6 of the same material as the lining plates and which cover the clamping plates 8 which retain the metal plates 2, 2<1> and the attached to these f oring plates 1, 1'.
