Description
Oppfinnelsen vedrorer en fremgangsmåte ved oppdeling og forming The invention relates to a method for dividing and shaping
av et plastisk porebetonglegeme med stort format til bygningselementer med mindre format enn legemet, hvor legemet vris stort sett 90° fra sin ved avbinding inntatte stilling og bringes i en utgangsstilling i hvilken det hviler med en smalside på et bevegelig, stort sett horisontalt underlag, slik at legemets store flater rettes hovedsakelig vertikalt. from a plastic aerated concrete body with a large format to building elements with a smaller format than the body, where the body is turned mostly by 90° from its position assumed during binding and brought into an initial position in which it rests with a narrow side on a movable, mostly horizontal surface, such that the body's large surfaces are oriented mainly vertically.
Med porebetong menes i denne forbindelse betongslag hvis volum-vekt er redusert ved tilveiebringelse av porer eller celler i betongen, f.eks. lettbetong i form av gass- og/eller skumbetong eller betongmateriale fremstilt ved kombinasjoner av gass- In this context, aerated concrete means concrete whose volume-weight has been reduced by providing pores or cells in the concrete, e.g. lightweight concrete in the form of gas and/or foam concrete or concrete material produced by combinations of gas
eller skumporoseringsmetoder med andre metoder. or foam porosis methods with other methods.
Foruten en fremgangsmåte vedrorer oppfinnelsen også et anlegg for dennes utforelse. In addition to a method, the invention also relates to a plant for its implementation.
Det er i og for seg fra f.eks. det norske patentskrift 88 226 kjent å vri en plastisk lettbetongblokk 90° fra dens ved avbindingen inntatte stilling og derefter oppdele og forme blok-ken til mindre elementer. Denne bearbeidelse har imidlertid vært forbundet med betydelige vanskeligheter da skader lett har oppstått på det plastiske materiale da blokkene som regel har betydelige dimensjoner. Således har hvis uhensiktsmessig rekkefolge er blitt anvendt mellom forskjellige operasjoner, stabler av oppdelte enheter rast ned og forårsaket oket spill, idet skjærsnittene er blitt urene i ytterkantene ved at bort-frest gods ble slynget inn i allerede ferdige snitt og fremfor alt målenoyaktigheten for de ferdige elementer har vært mindre tilfredsstillende. It is in and of itself from e.g. the Norwegian patent document 88 226 known to turn a plastic lightweight concrete block 90° from its position assumed at the time of setting and then divide and shape the block into smaller elements. However, this processing has been associated with significant difficulties as damage has easily occurred to the plastic material as the blocks usually have significant dimensions. Thus, if an inappropriate sequence has been used between different operations, stacks of divided units have collapsed and caused increased play, as the cutting sections have become unclean at the outer edges by milled away material being flung into already finished sections and above all the measuring accuracy of the finished elements have been less satisfactory.
Hensikten med oppfinnelsen er under opprettholdelse av hoy effektivitet ved fremstillingen å tilveiebringe en enkel og bil-lig oppdeling eller forming av plastiske stopelegemer til bygningselementer med mindre format enn legemet og med overlegent god målenoyaktighet. The purpose of the invention is, while maintaining high efficiency during production, to provide a simple and inexpensive division or shaping of plastic stopper bodies into building elements with a smaller format than the body and with superior measurement accuracy.
Fremgangsmåten ifolge oppfinnelsen kjennetegnes i det vesentlige av den kombinasjon at legemet befordres fra utgangsstillingen til en forste stasjon, ved hvilken i det minste én av legemets store flater gis forutbestemt form, fortrinnsvis ved hjelp av plan- og/eller profilfresing, at legemet fra den forste stasjon viderebefordres til en andre stasjon, hvor legemet ved hjelp av faste delingsorgan anordnet på tvers av legemets bevegelsesretning oppdeles i horisontale snitt orientert parallelt med legemets bevegelsesretning, og at legemet fra den andre stasjon befordres til en tredje stasjon ved hvilken det stoppes for vertikal oppdeling ved hjelp av vertikalt bevegelige delingsorgan, idet befordringen av legemet fra utgangsstillingen til den tredje stasjon gjennomfores med legemet alltid hvilende på underlaget og hvor underlaget beveger seg langs en eneste, hovedsakelig, rett eller lineær bane gjennom stasjonene. The method according to the invention is essentially characterized by the combination that the body is conveyed from the starting position to a first station, in which at least one of the large surfaces of the body is given a predetermined shape, preferably by means of plane and/or profile milling, that the body from the first station is conveyed to a second station, where the body is divided into horizontal sections oriented parallel to the direction of movement of the body by means of fixed dividing means arranged across the direction of movement of the body, and that the body from the second station is conveyed to a third station at which it is stopped for vertical division at by means of vertically movable dividing means, as the transport of the body from the starting position to the third station is carried out with the body always resting on the substrate and where the substrate moves along a single, mainly straight or linear path through the stations.
Under henvisning til tegningen skal nedenfor gis en nærmere beskrivelse av en utfbrelsesform valgt som eksempel på oppfinnelsen. With reference to the drawing, a detailed description of an embodiment chosen as an example of the invention will be given below.
På tegningen er fig. 1 et sterkt skjematisk sideriss av anlegget ifolge oppfinnelsen. In the drawing, fig. 1 a strong schematic side view of the plant according to the invention.
Fig. 2 er et planriss av anlegget i fig. 1.. Fig. 2 is a plan view of the facility in fig. 1..
Fig. 3 er et snitt efter linjen 3-3 i fig. 1 tatt på en fbrste stasjon for anlegget. Fig. 4 er et snitt efter linjen 4-4 tatt på en annen stasjon. Fig. 5 er et snitt efter linjen 5-5 tatt på en tredje stasjon for anlegget. Fig. 3 is a section along the line 3-3 in fig. 1 taken at a first station for the facility. Fig. 4 is a section along the line 4-4 taken at another station. Fig. 5 is a section along line 5-5 taken at a third station for the plant.
Gassbetong kan fremstilles på den måte at stopemasse som i det vesentlige består av et kiselsyreholdig materiale, et kalkhol-dig bindemiddel, et poredannende middel samt vann tappes i former, hvilke kan ha dimensjonene 600 x 240 x 60 cm. Efter itappingen i en form poroseres stopemassen under dannelse av forutbestemt porbsitet, hvorpå massen tillates å avbindes til plastisk selvbærende konsistens. Efter at massen på denne måte er avbundet til et selvbærende legeme, fjernes formen eller Aerated concrete can be produced in such a way that stoping compound which essentially consists of a silicic acid-containing material, a calcareous binder, a pore-forming agent and water is poured into molds, which can have the dimensions 600 x 240 x 60 cm. After pouring into a mold, the stoping mass is porous to form a predetermined porosity, after which the mass is allowed to set to a plastic self-supporting consistency. After the mass has been bound in this way into a self-supporting body, the form is removed or
deler av denne fra legemet som i blottlagt tilstand oppdeles og formes til bygningselementer av onsket format. Endelig un-derkastes det oppdelte og formede legeme en herdningsbehandling, fortrinnsvis dampherding. parts of this from the body which in the exposed state are divided and shaped into building elements of the desired format. Finally, the divided and shaped body is subjected to a hardening treatment, preferably steam hardening.
Oppdelingen finner sted på det trinn av fremstillingen som lig-ger mellom tidspunktet for legemets avforming og tidspunktet for legemets herding. The division takes place at the stage of production that lies between the time of shaping the body and the time of hardening of the body.
I fig. 1 og 2 betegner A legemets utgangssti11ing for oppdeling. B er en fbrste bearbeidelsesstasjon, C en annen bearbeidelsesstasjon, D en tredje bearbeidelsesstasjon og E en sluttstasjon for det oppdelte legemet. Selv om det er gunstig å forflytte det oppdelte legeme fra stasjon D til stasjonen E efter utfort oppdeling, kan legemet likeledes innta en endestilling ved stasjonen D. Legemet kan således videretransporteres til fore-kommende herdingssted enten direkte fra stasjonen D eller fra stasjonen E. In fig. 1 and 2, A denotes the body's starting path for division. B is a first machining station, C a second machining station, D a third machining station and E an end station for the split body. Although it is advantageous to move the divided body from station D to station E after further dissection, the body can also take up an end position at station D. The body can thus be transported to the existing curing site either directly from station D or from station E.
På tegningen er stopelegemet betegnet med 1. Som det sees, er legemet 1 såvel i utgangssti11ing som under oppdelingsprosessen anordnet med sin stbrre flate orientert stort sett vertikalt, hvilket betyr at legemet er blitt dreid 90° bort fra den ved stbpingen og avbindingen inntatte stilling. På denne måte vil bl.a. legemets opprinnelige overside 2, som er ujevn, være vertikalt orientert. Legemet 1 hviler med sin ene smallangside på et underlag 3 som med fordel kan være en del av den opprinnelige stopeform, nærmere bestemt en langsidevegg av formen. Underlaget 3, som under alle forhold skal være bevegelig langs en bane gjennom stasjonene B, C og D, kan igjen være anordnet på en vogn 4 hvis hjul 5 loper langs spor eller skinner 6. Ifolge oppfinnel-sens prinsipp er sporene eller skinnene 6 rette og er således anordnet at de forlbper i rett linje fra utgangsstiIlingen A til sluttstillingen E. Underlaget 3 kan med fordel være tilnærmel-sesvis like bredt som legemets 1 horisontalt rettede smalside. Derved vil legemets vertikale store flater ligge i umiddelbar nærhet av underlagets kanter. In the drawing, the stopping body is denoted by 1. As can be seen, the body 1, both in the initial state and during the splitting process, is arranged with its stiffer surface oriented largely vertically, which means that the body has been turned 90° away from the position taken during the stapling and tying. In this way, i.a. the body's original upper side 2, which is uneven, be vertically oriented. The body 1 rests with its one narrow long side on a base 3 which can advantageously be part of the original stop shape, more specifically a long side wall of the shape. The base 3, which under all conditions must be movable along a path through the stations B, C and D, can again be arranged on a carriage 4 whose wheels 5 run along tracks or rails 6. According to the principle of the invention, the tracks or rails 6 are straight and are arranged so that they continue in a straight line from the starting position A to the final position E. The substrate 3 can advantageously be approximately as wide as the horizontally oriented narrow side of the body 1. Thereby, the body's large vertical surfaces will lie in close proximity to the edges of the substrate.
Den fbrste bearbeidelsesstasjon B omfatter anordninger for å bearbeide eller forme legemets 1 overflater, eller ytterdeler, fortrinnsvis legemets to motstående store flater. Anordningens funksjoner og effekter kan da variere i avhengighet av bnsket utforming av de bygningselementer som fås av legemet. I fig. 1, 2 og 3 vises bearbeidelsesstasjonen B omfattende et par motstående roterbare planfresere 7 beregnet på å gi legemets 1 vertikale store flater bnsket planhet. For dette byemed er freserens freseorgan rette eller rettlinjede og består med fordel av utspente tråder. Videre omfatter stasjonen B et par motstående roterbare profilfresere 8 beregnet på å gi bnsket pro-filering i legemets 1 store flater. Den ene av freserne B The first processing station B comprises devices for processing or shaping the body's 1 surfaces, or outer parts, preferably the body's two opposite large surfaces. The device's functions and effects can then vary depending on the desired design of the building elements obtained from the body. In fig. 1, 2 and 3, the machining station B is shown comprising a pair of opposing rotatable face mills 7 designed to give the body 1's vertical large surfaces the desired flatness. For this byemed, the cutter's milling body is straight or rectilinear and advantageously consists of stretched threads. Furthermore, the station B comprises a pair of opposing rotatable profile cutters 8 intended to provide the desired profiling in the large surfaces of the body 1. One of the cutters B
kan f.eks. være beregnet på å utforme noter i et antall elementer, mens den motstående freser er beregnet på å utforme spor i elementene. can e.g. be designed to design notches in a number of elements, while the opposite milling cutter is designed to design grooves in the elements.
Istedenfor eller i kombinasjon med de roterbare planfresere 7 Instead of or in combination with the rotatable face mills 7
kan likeledes anvendes ett eller flere faste skjæreorgan med rettlinjet utstrekning, f.eks. en enkel, utspent tråd. Analogt med dette er det også mulig istedenfor eller i kombinasjon med profilfreserne 8 å anvende ett eller flere med fremspring for-synte profilorgan som er fast anordnet. De i stasjonen B fore-liggende bearbeidelsesorgan kan med fordel være anbragt på vertikale sbyler eller stolper 9. one or more fixed cutting means with a straight extension can also be used, e.g. a simple, stretched thread. Analogous to this, it is also possible instead of or in combination with the profile cutters 8 to use one or more profile members provided with protrusions which are fixedly arranged. The processing means present in station B can advantageously be placed on vertical troughs or posts 9.
Den andre bearbeidelsesstasjon C omfatter en eller flere grupper av faste oppdelingsorgan lo. I dette tilfelle består oppdelingsorganene av horisontale tråder som er utspent mellom parvis an-ordnede vertikale bommer eller stolper 11. Den innbyrdes av-stand mellom bommene 11 er så stor at legemet 1 kan passere mellom bommene. The second processing station C comprises one or more groups of fixed dividing bodies lo. In this case, the dividers consist of horizontal wires which are stretched between paired vertical booms or posts 11. The mutual distance between the booms 11 is so great that the body 1 can pass between the booms.
Den i fig. 1, 2 og 5 viste stasjon D omfatter en gruppe oppdelingsorgan 12 som angriper legemet 1 ovenfra. Oppdelingsorganene The one in fig. Station D shown in 1, 2 and 5 comprises a group of dividing means 12 which attack the body 1 from above. The divisional bodies
N 12, som med fordel består av utspente tråder, er anordnet i en ramme 13. Denne er med fordel dreibar om en akse beliggende parallelt med legemets 1 bevegelsesretning gjennom de forskjellige stasjoner. N 12, which advantageously consists of stretched threads, is arranged in a frame 13. This is advantageously rotatable about an axis situated parallel to the direction of movement of the body 1 through the various stations.
Det beskrevne anlegg arbeider på folgende måte. Fra utgangsstillingen A bringes legemet 1 til å bevege seg gjennom stasjonen B og stasjonen C frem til stasjonen D hvor det bringes til å stanse. Under forflyttingen gjennom stasjonene B og C The described facility works in the following way. From the starting position A, body 1 is made to move through station B and station C until station D, where it is brought to a stop. During the transfer through stations B and C
får legemets vertikale store flater dels bnsket bearbeidelse ved hjelp av f.eks. de på tegningen viste fresere 7 og 8, og dels oppdeles legemet i lengderetningen i horisontale snitt av organene eller trådene lo. I stasjonen D oppdeles legemet tvers på sin lengderetning i vertikale snitt ved hjelp av organene eller trådene 12. Oppdelingen i vertikal retning i stasjonen D skjer ved nedsvingning av rammen 13, som efter at trådene har nådd underlaget 3 eller i nærheten av dette igjen svinges opp ut av berbring med legemet 1. Derefter kan det således opp- The body's vertical large surfaces are given the desired processing with the help of e.g. the cutters 7 and 8 shown in the drawing, and partly the body is divided in the longitudinal direction into horizontal sections of the organs or threads lo. In station D, the body is divided across its longitudinal direction into vertical sections with the help of the organs or threads 12. The division in the vertical direction in station D takes place by swinging down the frame 13, which is swung up again after the threads have reached the substrate 3 or close to it out of contact with the body 1. Then it can thus
delte legeme enten forflyttes til endestiIlingen E eller videretransporteres direkte til herding. the split body is either moved to the final stage E or transported directly to curing.
Oppfinnelsen er selvsagt ikke begrenset til bare den foran beskrevne og på tegningen viste utfdrelsesform. Det vesentlige er at legemet 1 fra utgangsstillingen A til endestillingen D The invention is of course not limited to just the embodiment described above and shown in the drawing. The essential thing is that the body 1 from the starting position A to the end position D
eller E stadig hviler på underlaget og at underlaget beveger seg langs en enkelt bane. Videre kan legemet 1 stoppes ved vilkårlig valgt sted langsefter banen 6, selv om det er for-delaktigst å forflytte legemet direkte fra utgangsstillingen A til stasjonen D. Det er således mulig å foreta en rekke mo-difikasjoner innenfor rammen av de efterfolgende patentkrav. or E constantly rests on the substrate and that the substrate moves along a single path. Furthermore, the body 1 can be stopped at an arbitrarily chosen place along the path 6, although it is most advantageous to move the body directly from the starting position A to the station D. It is thus possible to make a number of modifications within the framework of the following patent claims.
