Opfindelsen angår en fremgangsmåde til kunstig forældelse af betonsten ved slagpåvirkning med en hammerindretning, hvis hammerværktøjer påvirker de på et fremstillingsbræt hvilende, endnu ikke fuldstændigt hærdede betonsten under den konti-5 nuerlige fremstillingsproces i et stenanlæg, hvorved de øvre stenkanter afslås, medens oversiden af betonstenene dog forbliver glatte. Opfindelsen angår endvidere et apparat til udøvelse af fremgangsmåden samt kunstigt forældede betonsten med en synlig overflade, som er bearbejdet med dette apparat 10 med stumpe slagflader.BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a method of artificially aging the concrete by impact with a hammer device, the hammer of which affects the concrete resting on a board, not yet fully cured during the continuous manufacturing process in a stone plant whereby the upper stone edges are turned off while the top of the concrete however, they remain smooth. The invention further relates to an apparatus for carrying out the method as well as artificially aged concrete bricks with a visible surface which is machined with this apparatus 10 with blunt impact surfaces.
Betonsten til brolægning finder bred anvendelse ved vej-, gade-og pladsbygning. Ofte sker det herved, at man må anbringe gammel og ny brolægning ved siden af hinanden. Specielt når det drejer sig om sanering i gamle byer, dukker spørgsmålet 15 op, om det f.eks. går an at forsyne gader, veje og pladser med en ny brolægning, som på harmonisk vis passer ind i det af tidens tand prægede udseende af gadebilledet. Da det ved støbte betonbrosten drejer sig om et nyt konstruktionsmateriale, har det vist sig, at en kunstig forældelse af 20 betonstenene er nødvendig.The concrete for paving is widely used in road, street and space construction. Often this means that one must place old and new paving side by side. Especially when it comes to decontamination in old cities, the question 15 arises whether, for example. It is possible to provide streets, roads and squares with a new paving, which harmoniously fits into the appearance of the street image of the time tooth. Since cast concrete is a new construction material, it has been found that an artificial obsolescence of the 20 concrete bricks is necessary.
Fra DE-OS-36 21 276 kendes en fremgangsmåde og et apparat af den indledningsvis nævnte type. Der anvendes stokjern, som under kraftig belastning påvirker overfladen på brosten, som er anbragt i et enkelt lag på en plade. Herved bliver på den 25 ene side kanterne brudt, og på den anden side får brostenenes overflade, som følge af bearbejdningen med de skarpkantede stokjern, en markant og i forhold til en gammel stenoverflade nærmest atypisk struktur. Den således bearbejdede brosten fremtræder herefter nærmere som en struktursten end som en 30 kunstig forældet brosten. Derudover er der i dette kendte skrift beskrevet, at der kun kan foregå afslåning af brostenenes kanter. Stenoverfladerne forbliver derimod ubearbejdede. Kanterne på en således bearbejdet brosten udviser for det første et urent brudbillede, og for det andet forbliver 35 overfladen fuldstændig ubearbejdet. En yderligere ulempe ved 2 DK 171817 B1 denne fremgangsmåde er, at under behandlingen af stenoverfladen i et stenfremstillingsanlæg med integreret stokjern-apparat må hvert stenlag udtages af den ellers kontinuerlige strøm af sten i anlægget.DE-OS-36 21 276 discloses a method and apparatus of the type mentioned above. Studs are used which, under heavy loads, affect the surface of the cobblestone which is placed in a single layer on a plate. In this way, the edges are broken on one side and on the other hand the surface of the cobblestones, as a result of the machining with the sharp-edged iron bars, gives a distinct and almost atypical structure in relation to an old stone surface. The cobble thus worked appears more closely as a structural stone than as an artificially outdated cobblestone. In addition, this prior art discloses that only the edges of the cobblestones can be cut off. The stone surfaces, on the other hand, remain unprocessed. First, the edges of a cobble thus worked exhibit an unclean fracture image and, second, the surface remains completely unworked. A further disadvantage of this method is that during the treatment of the stone surface in a stone making plant with integrated iron core apparatus, each stone layer must be removed from the otherwise continuous flow of stones in the plant.
5 Formålet med opfindelsen er at tilvejebringe en fremgangsmåde og et apparat af den indledningsvis angivne art, som med henblik på at give betonsten et ældet udseende uden påvirkning af stenfremstillingsanlæggets fremføringsstrøm kan give betonstenenes synlige flader en sådan mekanisk efterbehandling, 10 at de trods en mekanisk overfladebehandling får et udseende som svarer til en naturlig forældelsestilstand. Det er yderligere et formål at kunne fremstille overfladebehandlede betonsten, især brosten.The object of the invention is to provide a method and apparatus of the kind mentioned in the preamble, which, in order to give the concrete a aged appearance without affecting the flow of the stone-making plant, can give the concrete surfaces visible such mechanical finishing, 10 despite a mechanical surface treatment. gets a look that is similar to a natural state of aging. It is a further object to be able to manufacture surface-treated concrete bricks, in particular cobblestones.
Til opfyldelse af dette formål er fremgangsmåden ifølge op-15 findelsen ejendommelig ved, at stenoverfladerne og stenkanterne bearbejdes, og hammerværktøjerne har stumpe eller afrundede slagflader.For the purpose of this invention, the method according to the invention is characterized in that the stone surfaces and the stone edges are machined and the hammer tools have blunt or rounded impact surfaces.
Bearbejdningen af overfladen med en hammer som slagværktøj, dvs. en i forhold til et stokjern stump genstand, muliggør 20 for det første en ren brydning af kanterne og for det andet også en overfladebehandling, som uden antydning af, at det drejer sig om en efterbearbejdning, giver den synlig flade et udseende, som snarere giver den synlige overflade udseende af en form for patina end en strukturoverflade, som den, der 25 opnås ved anvendelse af den i DE-OS 36 21 276 beskrevne fremgangsmåde .The machining of the surface with a hammer as a percussion tool, ie. one relative to a hollow-iron blunt object, 20 allows, firstly, a clean breaking of the edges and, secondly, a surface treatment which, without suggesting that it is a finishing work, gives the visible surface an appearance which rather gives the visible surface appearance of a form of patina other than a structural surface such as that obtained by using the method described in DE-OS 36 21 276.
Den på et fremstillingsbræt anbragte fremstillingsformation af betonsten bliver til stadighed fremført under den herover monterede hammerindretning. Herved sker der samtidigt en be-30 vægelse af indretningen på tværs af fremføringsretningen. Herved bliver en ensidig orientering af de af hammerslagene frembragte spor på den synlige flade udelukket, og der opnås en naturligt udseende overflade.The manufacturing formation of the concrete brick placed on a production board is constantly carried under the hammer device mounted above. Thereby, the device is moved simultaneously across the feed direction. In this way, a unilateral orientation of the grooves produced by the hammer blows on the visible surface is excluded and a natural looking surface is obtained.

De værktøjer, der er monteret i hammerindretningen ifølge opfindelsen til bearbejdning af betonsten, er hammerværktøj er med afrundede slagflader. Ved denne udformning af slagfladerne forhindres, at overfladerne får kraftige kløfter, som vil 5 modvirke forældelseseffekten. Derimod opnås en ringe lidt uregelmæssig materialefjernelse, der er typisk for forældelsesprocesser. Hammerindretningen består af et stativ, hvori der på tværs af fremstillingsformationens fremføringsretning er monteret flere hammeraggregater på en fælles bærer. Herved 10 opnås fælles fremføring af hammerværktøjerne.The tools mounted in the hammer device according to the invention for machining concrete bricks are hammer tools with rounded impact surfaces. By this design of the impact surfaces, the surfaces are prevented from causing heavy gaps which will counteract the aging effect. In contrast, a slight irregular material removal is typical, which is typical of aging processes. The hammer assembly consists of a rack in which several hammer assemblies are mounted on a common carrier across the feed direction of the manufacturing formation. This results in 10 joint advancement of the hammer tools.
Til opnåelse af størst mulig bearbejdningstæthed er hammeraggregaterne anbragt i to rækker, idet de er anbragt forsat i mellemrummene i forhold til hinanden på stativets bærer. Til sikring af fremstillingsformationen på fremstillingsbrættet 15 under slagpåvirkningen ved hjælp af hammerindretningen er der tilvejebragt en bevægelig holdeindretning.To obtain the highest machining density possible, the hammer assemblies are arranged in two rows, positioned perpendicular to each other on the support of the rack. To secure the manufacturing formation on the manufacturing board 15 during impact by the hammer device, a movable holding device is provided.
I det efterfølgende beskrives en foretrukken udførelsesform for en hammerindretning ifølge opfindelsen, samt anbringelsen af samme hammerindretning i forbindelse med et betonfremstil-20 lingsanlæg til udøvelse af fremgangsmåden ifølge opfindelsen, samt en dermed fremstillet betonsten (brosten) under henvisning til tegningen, hvor: fig. 1 viser et område i en fremstillingsformation, set ovenfra, 25 fig. 2 det i fig. 1 viste område af fremstillingsformationen, set fra siden, fig. 3 en hammer indretning, set i området af en transportør til betonsten, fig. 4 en holdeindretning, der udgør en enkelt del af den i 30 fig. 3 viste hammerindretning, set ovenfra, 4 DK 171817 B1 fig. 5 den i fig. 3 viste hammer indretning, set fra siden på langs af transportbanen, og fig. 6 skematisk et stenfremstillingsanlæg med hammerindretning på tørresiden, set ovenfra.In the following, a preferred embodiment of a hammer device according to the invention is described, as well as the placement of the same hammer device in connection with a concrete manufacturing plant for carrying out the method according to the invention, and a concrete stone (cobblestone) thus made with reference to the drawing, in which: fig. 1 is a top view of an area of a manufacturing formation; FIG. 2 shows the embodiment of FIG. 1 is a side view of the manufacturing formation; FIG. 3 shows a hammer device, seen in the region of a concrete brick conveyor; FIG. 4 shows a holding device which forms a single part of the one shown in FIG. 3 is a top view of the hammer device, FIG. 5 is the one shown in FIG. 3 is a side elevational view of the conveyor path; FIG. 6 is a schematic top view of a stone-making plant with a hammer device on the drying side.
5 Betonsten 10 fremstilles som regel i kendte stenfremstillingsanlæg (fig. 6) . Disse er opbygget af en stenfremstillingsmaskine 11, en transportørbane 12, fortrinsvis i form af et kontinuerligt bevægeligt endeløst transportbånd eller lignende, en tværfører i form af en på tværs af transportbanens 10 12 fremføringsretning frem og tilbage bevægelig gaffelløfte vogn 13, ved hjælp af hvilken nyformede betonsten liggende på paletter, henholdsvis fremstillingsbrædder 14 kan føres ind i et tørrekammer 15, og efter tørringen kan fjernes igen, og en nærmest parallelt med den første transportør 12 forløbende 15 yderligere transportbane 16. Tørrekammeret 15 eller flere heraf er anbragt imellem transportørbanerne 12 og 16. Transportørbanen 12 er en del af vådbetonsiden, og transportbanen 16 er en del af tørbetonsiden af fremstillingsanlægget. Ved hjælp af en stabiliseringsindretning 17 fjernes de tørrede 20 betonsten 10 fra tørbetonsidens transportbånd 16 og herefter stables de oven på hinanden som færdige stenpakninger 18. Stenpakningerne 18 kan transporteres ved hjælp af en gaffelløftevogn 19 til oplagringpladsen. Tørbetonsidens transportørbane 16 er ligeledes som vådbetonsidens transportør-25 bane 12 opbygget som en endeløs transportør, f.eks. i form af et kontinuerligt drevet endeløst transportbånd eller i form af en skinne- henholdsvis kædetransportør.5 Concrete 10 is usually manufactured in known stone-making plants (Fig. 6). These are constructed of a stone-making machine 11, a conveyor track 12, preferably in the form of a continuously moving endless conveyor belt or the like, a transverse guide in the form of a forward and backwardly moving fork-lift carriage 13 by means of which the newly formed the concrete stone lying on pallets or manufacturing boards 14, respectively, can be introduced into a drying chamber 15 and after the drying can be removed again, and a further transport path 16. Nearly parallel to the first conveyor 12, the drying chamber 15 or more thereof is arranged between the conveyor paths 12 and 16. The conveyor web 12 is part of the wet concrete side and the conveyor web 16 is part of the dry concrete side of the manufacturing plant. By means of a stabilizing device 17, the dried concrete blocks 10 are removed from the conveyor belt 16 of the dry concrete side and then stacked on top of one another as finished stone packages 18. The stone packages 18 can be transported by means of a forklift truck 19 to the storage place. The conveyor web 16 of the dry concrete side is likewise constructed as the wet concrete conveyor web 12 of an endless conveyor, e.g. in the form of a continuously operated endless conveyor belt or in the form of a rail or chain conveyor.
Gaffelløftevognen 13 kan fortrinsvis køres frem og tilbage på to parallelle skinner 20 i retning af dobbeltpilen 21. Tomme 30 fremstillingsbrædder 14 transporteres via en transportør 22 til stenfremstillingsmaskinen 11. Transportøren 22 er fortrinsvis en bånd-, rulle- eller kædetransportør.The fork lift truck 13 can preferably be driven back and forth on two parallel rails 20 in the direction of the double arrow 21. Empty production boards 14 are conveyed via a conveyor 22 to the stone-making machine 11. The conveyor 22 is preferably a belt, roller or chain conveyor.
Ved det udførelseseksempel, der er vist i fig. 6, er der i 5 DK 171817 B1 nærheden af den på tørbetonsiden placerede transportør placeret en hammerindretning 23, som i det efterfølgende vil blive beskrevet i detaljer. Hammerindretningen 23 er integreret i produktionsprocessen, således at behandlingen af betonstenene 5 ikke påvirker fremstillingsforløbet og især ikke forhaler det.In the embodiment shown in FIG. 6, in the vicinity of the conveyor located on the dry concrete side, a hammer device 23 is placed, which will be described in detail below. The hammer device 23 is integrated into the production process so that the processing of the concrete blocks 5 does not affect the production process and in particular does not delay it.
Som vist i fig. 3 og 5, er hammerindretningen 23 anbragt fast oven over transportørbanen 16. De væsentligste bestanddele af hammerindretningen 23 er hammeraggregater 25, som er monteret 10 på en højdejusterbar drager 24.As shown in FIG. 3 and 5, the hammer device 23 is fixed above the conveyor path 16. The major components of the hammer device 23 are hammer assemblies 25 which are mounted 10 on a height-adjustable carrier 24.
De pneumatisk drevne hammeraggregater 25 omfatter hammerværktøjer 26, som ved hjælp af passende trykluftstyring kan bevæges lodret frem og tilbage på en sådan måde, at de på overfladen af de neden under fremførte betonsten virkende ham-15 merværktøjers 26 slagfrekvens og slagstyrke kan reguleres.The pneumatically driven hammer assemblies 25 comprise hammer tools 26 which can be moved vertically back and forth by appropriate compressed air control in such a way that the impact frequency and impact strength of hammer tools 26 operating below the concrete conveyed below can be controlled.
I fig. 1 og 2 er bearbejdningen af betonstenene 10 ved hjælp af hammerværktøjerne 2 6 vist skematisk. Fig. 1 viser et udsnit af et lag af betonsten 10 på et fremstillingsbræt 14.In FIG. 1 and 2, the machining of the concrete blocks 10 by means of the hammer tools 26 is shown schematically. FIG. 1 shows a section of a layer of concrete 10 on a production board 14.
Den temmelige tilfældige placering af betonstenene 10 i dette 2 0 eksempel skal kun vise, at det ikke er en forudsætning for bearbejdningen af betonstenene 10 med hammerværktøjerne 26, at de er anbragt i et ordnet lag, således som det før i tiden var tilfældet under fremstillingen i et stenfremstillingsanlæg. Betonstenene 10 fremføres i retning af pilen 27 under de 25 i tværsnit viste hammerværktøjer 26. Samtidig udfører de på bæreren 24 (fig. 3) anbragte hammerværktøjer en frem- og tilbagegående tværbevægelse i retning af dobbeltpilen 28. Overlejringen af denne tværbevægelse med den fremadgående bevægelse af betonstenene 10 i fremføringsstrømmen fra stenfrem-30 stillingsanlægget 11 har til følge, at hammerværktøjerne 26 påvirker hele oversiden af betonstenene 10 under fremførelsesbevægelsen. Når hammerværktøjerne 26 med deres afrundede slagflader 29 rammer inden for området af betonstenenes 10 øvre kanter 30, sker der en afbrækning af betonen. I det om- 6 DK 171817 B1 råde, der ligger tilstrækkelig langt fra de øvre kanter 13 på betonstenene 10, sker der en punktfortnig overfladekompression af betonen. Oversiden forbliver i sig selv glat uden at virke struktureret eller furet som følge af den mekaniske behand-5 ling, men den får dog en art patina på grund af den punktfor-mige slagpåvirkning med de afrundede slagflader 29 på hammerværktøjerne 26, hvilket medfører et ældet udseende.The rather random placement of the concrete bricks 10 in this example is only to show that it is not a prerequisite for machining the bricks 10 with the hammer tools 26 that they are arranged in an orderly layer, as was the case in the past during manufacture. in a stone-making plant. The concrete blocks 10 are advanced in the direction of arrow 27 below the hammer tools 26 shown in cross-section. At the same time, the hammer tools placed on the carrier 24 (Fig. 3) perform a reciprocating cross movement in the direction of the double arrow 28. The overlay of this transverse movement with the forward movement As a result of the concrete blocks 10 in the feed stream from the stone making station 11, the hammer tools 26 affect the entire upper surface of the concrete stones 10 during the feed movement. When the hammer tools 26, with their rounded impact faces 29, strike within the region of the upper edges 30 of the concrete bricks 10, the concrete is broken. In the area sufficiently far from the upper edges 13 of the concrete bricks 10, a punctured surface compression of the concrete takes place. The upper side itself remains smooth without appearing to be textured or grooved due to the mechanical treatment, however, it does get a kind of patina due to the punctual impact with the rounded impact faces 29 on the hammer tools 26, resulting in an aged appearance.
Mens de i to rækker, hver især i hinandens mellemrum på bæreren 24 anbragte hammeraggregater 25 påvirker de på fremstil-10 lingsbrættet 14 anbragte lag af betonsten 10, er laget fastholdt på fremstillingsbrædderne 14 ved hjælp af en holdeindretning 31, da de ellers på grund af de fra bearbejdningen opståede vibrationer ville kunne bevæges, således at betonstenene 10 vil kunne føres sideværst væk fra fremstillings-15 brættet 14.While in two rows, each at intervals of one another on the carrier 24, hammer assemblies 25 affect the layers 10 of the concrete 10 placed on the manufacturing board 14, the layer is retained on the manufacturing boards 14 by means of a holding device 31, otherwise due to the vibrations resulting from the machining could be moved so that the concrete blocks 10 could be moved laterally away from the manufacturing board 14.
Ved en bearbejdning af- betonstenene 10 med hammerindretningen 23 i et stenfremstillingsanlæg udfører bæreren 24 samt holde-indretningen 31 sideværts bevægelser, der er koblet sammen.In a machining of the concrete stones 10 with the hammer device 23 in a stone making plant, the carrier 24 and the holding device 31 perform lateral movements which are coupled together.
Når et fremstillingsbræt 14 med et lag af betonsten 10 nærmer 20 sig hammerindretningen 23, bliver holdeindretningen 31 ved hjælp af to pneumatisk styrede stempel-cylinderenheder 32 anbragt på fremstillingsbrættet 14. Holdeindretningen 31 føres ved hjælp af glidesko 33 i føringsskinner 34 og kan på denne måde følge transportbåndets 15 fremføringsbevægelse.As a manufacturing board 14 with a layer of concrete brick 10 approaches 20 the hammer device 23, the holding device 31 is mounted on the production board 14 by means of two pneumatically controlled piston cylinder units 14. The holding device 31 is guided by sliding shoes 33 in guide rails 34 and can in this way following the conveyor movement of the conveyor belt 15.
25 Når fremstillingsbrættet 14 når rækken af hammeraggregater 25, sænkes bæreren 24, aktiveret af en ikke vist føler, så langt ned, at hammeraggregaterne 25, som ligeledes aktiveres af en ikke vist føler, og som sættes i gang ved berøringen af betonstenene 10, kan bearbejde de nedenfor fremførte beton-30 sten 10. Nedsænkningen af bæreren 24 sker pneumatisk via en stempel-cylinderenhed 35. Samtidig med påbegyndelsen af bearbejdningen bringes bæreren 24 via de pneumatisk styrede stempel -cylinderenheder 36 i den allerede beskrevne frem- og tilbagegående tværbevægelse. Efter at fremstillingsbrættet 14 35 har passeret hammerindretningen 23, bevæges bæreren 24 medWhen the manufacturing board 14 reaches the row of hammer assemblies 25, the carrier 24, activated by a sensor not shown, is lowered so far that the hammer assemblies 25, which are also activated by a sensor not shown, and which are actuated by the touch of the concrete bricks 10, can 10. The submergence of the carrier 24 takes place pneumatically via a piston-cylinder unit 35. Simultaneously with the commencement of the processing, the carrier 24 is brought via the pneumatically controlled piston-cylinder units 36 in the reciprocating transverse movement already described. After the manufacturing board 14 35 has passed the hammer device 23, the carrier 24 is moved
