Menetelmå ja laite betoniraudoitteiden valmistamiseksiMethod and apparatus for making concrete reinforcements

Keksinnon kohteena on menetelmå betoniraudoitteiden valmistamiseksi, jossa menetelmåsså raudoitteen pituus-5 suuntaiset betoniteråkset asetetaan raudoitteen vaatimaan muotoon ja niiden ympårille kierretåån olennaisesti val-mistettavan raudoitteen pituudelle spiraalimaisesti hakas-lanka, joka kiinnitetåån hitsaamalla betoniteråksiin niiden risteåmiskohdilta.The invention relates to a method for manufacturing concrete reinforcements, in which concrete steels in the longitudinal direction of the reinforcement are placed in the shape required by the reinforcement and around them the length of the reinforcement to be manufactured is helically wound in a spiral wire, which is fixed by welding to the reinforcing bars.

10 Edelleen keksinnon kohteena on laite menetelmån toteuttamiseksi, jossa laitteessa on ohjausvåline betoni-teråsten ohjaamiseksi raudoitteen mukaiseen asentoon, kiertovålineet hakaslangan kiertåmiseksi spiraalimaisesti betoniteråsten ympårille ja hitsausvålineet hakaslangan 15 hitsaamiseksi betoniteråksiin niiden risteåmiskohdilta.The invention further relates to an apparatus for carrying out the method, the apparatus comprising guide means for guiding the reinforcing steels to a position according to the reinforcement, rotating means for helically winding the barbed wire around the reinforcing bars and welding means for welding the barbed wire 15 to the reinforcing bars.

Valmistettaessa betoniraudoitteita erilaisiin pila-reihin, teråsbetonipalkkeihin ja paaluihin ne erityisesti teollisessa betonielementtituotannossa valmistetaan ja kootaan tarvittavan muotoisiksi valmiiksi raudoitteiksi, 20 jonka jålkeen ne siirretåån varsinaiseen valuvaiheeseen betonin valamiseksi tuotteeseen. Raudoitteiden valmistaminen kåsin ja kåsityonå on raskasta ja hidasta sekå tyovoi-makustannuksiltaan kallista. Tåmån vuoksi raudoitteiden valmistusta on pyritty mekanisoimaan.When manufacturing concrete reinforcements for various columns, reinforced concrete beams and piles, especially in industrial precast concrete production, they are manufactured and assembled into prefabricated reinforcements of the required shape, 20 after which they are transferred to the actual casting stage to pour concrete into the product. Manufacturing reinforcements by hand and by hand is heavy and slow and expensive in terms of labor costs. For this reason, efforts have been made to mechanize the manufacture of reinforcements.

25 PCT-hakemuksessa V085/05053 on esitetty ratkaisu, jossa betoniteråkset syotetåån keloilta teråkset tiettyyn raudoitteen poikkileikkauksen mukaiseen jårjestykseen asettavan ohjaimen låpi. Hakaslanka, jolla betoniteråkset kytketåån yhteen, muotoillaan erillisesså muotissa ennalta 30 mååråtyn muotoiseksi, katkaistaan ja hitsataan påiståån kiinteåksi kehråksi. Tåmån jålkeen automaattinen siirto-laite siirtåå muodostetun kehån betoniteråsten våliin, jonka jålkeen se hitsataan niihin kiinni. Esitetyn lait-teiston hankaluutena on, ettå valmistettavan raudoitteen 35 muoto on tiukasti sidottu syottolaitteesta ohjaimeen val- 2 miiksi tehtyihin reikiin ja sitå voidaan mitoiltaan muut-taa vain yhdesså suunnassa. Edelleen raudoitteen muotoa rajoittaa se, ettå valmiiksi keha tåytyy kyeta siirtåmåån betonirautojen vålistå paikalleen oikeassa asennossaan, 5 joten myos jokaiselta sivultaan betoniraudoilla varustettu raudoite ei ole mahdollinen kyseisesså ratkaisussa.PCT application V085 / 05053 discloses a solution in which reinforcing bars are fed from coils through a guide which places the steels in a certain order according to the cross-section of the reinforcement. The hook wire with which the reinforcing steels are joined together is formed in a separate mold into a predetermined shape, cut and welded to a solid spindle. The automatic transfer device then transfers the formed ring to the reinforcing bars, after which it is welded to them. A disadvantage of the apparatus shown is that the shape of the reinforcement 35 to be manufactured is tightly bound to the holes made in the guide from the feeder and can only be changed in one direction. The shape of the reinforcement is further limited by the fact that the perimeter must already be able to move between the reinforcing bars in its correct position, 5 so that reinforcement with reinforcing bars on each side is also not possible in this solution.

DE-hakemusjulkaisussa 3221671 puolestaan on esitet-ty ratkaisu, jossa påiståån erilliseen tukielementtiin kiinnitetyt betoniraudat vedetåån ohjaimen lapi ja hakas-10 lanka kierretåån niiden ympårille samalla, kun se hitsa-taan aina kohdalle tulevaan betonirautaan. Tåsså ratkaisussa betoniraudat kiinnittyvåt niiden ympåri spiraalimai-sesti kiertåvållå hakaslangalla haluttuun muotoon. Julkaisussa esitetyssa ratkaisussa tåytyy jokainen betonirauta 15 ensiksikin kiinnittåå tukielementtiin, jotta ne voitaisiin vetaå samanaikaisesti eteenpain. Edelleen ratkaisussa tåytyy hitsauslaitteistoon kuuluvaa rumpua pyorittåå koko ajan muodostuvan raudoitteen ympåri, jotta hakaslanka saa-taisiin hitsatuksi siihen kiinni, mikå tekee rakenteen 20 monimutkaiseksi. Edelleen kyseisellå rakenteella tåytyy kutakin raudotemallia vårten muodostaa erillinen muotti ja vetotuki, jotta niiden valmistus olisi mahdollista. Lisåk-si kyseisesså ratkaisussa ei ole mahdollista valmistaa esimerkiksi nelikulmaisia betoniraudoitteita, vaan rakenne 25 rajoittuu pelkåståån pydråmuotoisiin raudoitteisiin.DE-A-3221671, on the other hand, discloses a solution in which the reinforcing bars attached to a separate support element are pulled through the guide and the hook-10 wire is wound around them while always being welded to the approaching reinforcing iron. In this solution, the reinforcing bars are attached to the desired shape by a spiral wire rotating around them in a spiral. In the solution presented in the publication, each rebar 15 must first be fastened to a support element so that they can be pulled forward at the same time. Furthermore, in the solution, the drum belonging to the welding equipment has to be rotated around the constantly forming reinforcement in order to have the hooked wire welded to it, which makes the structure 20 complicated. Furthermore, this structure has to form a separate mold and traction support for each rail model in order to be able to manufacture them. In addition, in this solution it is not possible to produce, for example, rectangular concrete reinforcements, but the structure 25 is limited only to hydroformed reinforcements.

Tåmån keksinnon tarkoituksena on saada aikaan sel-lainen menetelmå ja laite betoniraudoitteiden valmistami-seksi, jolla valmistaminen on yksinkertaista ja nopeaa ja jossa samalla laitteella voidaan valmistaa useita eri muo-30 toisia, pituisia ja eri tavalla raudoitettuja raudoittei-ta. Tåmå saadaan keksinnon mukaisella menetelmållå aikaan siten, ettå betoniteråkset asetetaan ensin ainakin olen-naisesti niiden mittaisen kierråtystukin ulkopinnalle kierråtystukissa oleviin kiinnittimiin betoniteråsten pi-35 tåmiseksi paikallaan ennen hakaslangan kiertåmistå valmis- il 90833 3 tettavan raudoitteen poikkileikkauksen mukaiseen asentoon, ettå hakaslanka kiinnitetåån yhteen betoniteråkseen ja ettå hakaslanka kierretåån betoniteråsten ympårille spi-raalimaiseen muotoon pyorittåmållå kierråtystukkia pituus-5 akselinsa ympåri ja siirtåmållå samanaikaisesti hakaslan-kaa kierråtystukin suhteen sen pituussuunnassa, jonka jål-keen valmis raudoite poistetaan kierråtystukin pååltå sen pituussuuntaan siirtamållå.The object of the present invention is to provide a method and an apparatus for the production of concrete reinforcements, in which the preparation is simple and fast and in which several different shapes, lengths and differently reinforced reinforcements can be produced with the same device. This is achieved by the method according to the invention in that the reinforcing steels are first the hook wire is wound around the reinforcing bars in a spiral shape by rotating the recirculation log about its length-5 axis and simultaneously moving the hook wire relative to the recirculation support in its longitudinal direction, after which the finished reinforcement is removed from the rotation support.

Keksinnon mukaiselle laitteelle on ominaista, ettå 10 ohjausvåline on ainakin olennaisesti betoniteråsten mit-tainen kierråtystukki, jonka ulkopinnalle betoniteråkset asetetaan, ja ettå kiertovålineisiin kuuluu kierråtysko-neisto kierråtystukin pyorittåmiseksi pituussuuntaisen akselinsa ympåri ja siirtovålineet hakaslangan siirtåmi-15 seksi kierråtystukin suhteen sen pituussuunnassa.The device according to the invention is characterized in that the guide means 10 is a recirculation support at least substantially the length of the reinforcing bars, on the outer surface of which the reinforcing bars are placed, and that the rotating means comprise a recirculation mechanism

Keksinnon olennaisena ajatuksena on, ettå betoniteråkset kiinnitetåån raudoituksen valmistamista vårten suunnilleen niiden pituiseen tai pitempåån tukeen eli kierråtystukkiin, jossa teråksen ovat valmista raudoitetta 20 vastaavassa asemassa, jonka jålkeen niihin on helppo kiin-nittåå teråkset lopullisesti paikallaan pitåvå ja valmista tuotetta poikittaissuunnassa tukeva hakaslanka pyorittå-mållå kierråtystukkia pituusakselinsa ympåri ja syottåmål-lå hakaslankaa teråsten ympårille spiraalimaisesti sekå 25 hitsaamalla ne teråsten ja hakaslangan risteåmiskohdissa kiinni toisiinsa. Menetelmån ja laitteen avulla betonirau-doitteiden valmistus on helppo toteuttaa erilaisille rau-doitemalleille ilman raskasta kåsityotå ja samanlaisia raudoitteita on helppo tehdå nopeasti samoinkuin raudoite-30 mallin vaihtaminen on helppo tehdå. Edelleen keksinnon etuna on, ettå valmistus on helppo automatisoida ja toteuttaa se tuotantolinjamuodossa, mikå vielå tehostaa val-mistusta.The essential idea of the invention is that, for the production of reinforcement, the reinforcing bars are fastened to a support approximately their length or longer, i.e. a recycling log, where the steels are in a position corresponding to the finished reinforcement 20, after which it is easy to recirculating logs about their longitudinal axis and feeding the hook wire around the steels in a spiral manner and by welding them together at the intersections of the steels and the wire. With the method and the device, the production of concrete reinforcements is easy to implement for different reinforcement models without heavy manual work and similar reinforcements are easy to make quickly, just as it is easy to change the reinforcement-30 model. A further advantage of the invention is that the production is easy to automate and implement it in the form of a production line, which further enhances the production.

Laitteistoon kuuluu edelleen kierrå-5 tystukin 5 alla oleva rullapoytå 8, jolla valmiit betoni-raudoitteet siirretaan pois ja kiskojen 9 varassa kierrå-tystukin 5 ja rullapoydån 8 suuntaisesti liikkuva ohjaus-vaunu 10. Ohjausvaunussa 10 on ohjaaja 11 ja sen takaosas-sa hakaslangan 12 muodostama kela. Ohjausvaunussa 10 on 10 edelleen hakaslangan ohjain 13, jonka avulla hakaslanka 12 ohjautuu oikeaan paikkaan kierratystukilla 5 oleviin beto-nirautojen 2 suhteen seka hitsauspåå 14, joka hitsaa hakaslangan 12 kiinni betonirautoihin 2.

The apparatus further comprises a roller table 8 under the turntable 5, by means of which the finished concrete reinforcements are moved away and a guide carriage 10 moving parallel to the turntable 5 and the roller 8 on the rails 9. The guide carriage 10 has a guide 11 and a hook wire 12 at its rear. formed by a coil. The guide carriage 10 further comprises a hook wire guide 13 by means of which the hook wire 12 is guided to the correct position with respect to the concrete bars 2 on the torsion supports 5 and a welding head 14 which welds the hook wire 12 to the concrete bars 2. The guide carriage 10 further has a hook wire 15 with a spool of crochet thread 12 right straight.

Betoniraudoitetta valmistaessa valmiiksi katkotet-tuja betoniteraksia 2 siirretaan siirtolaitteella 4 kier-ratystukille 5 siinå oleviin kuvioiden 3-9 yhteydessa tarkenunin selostettaviin pitimiin, jonka jalkeen hakaslan-20 ka 12 hitsataan kiinni ensimmåiseen betoniteråkseen 2 ja kierråtystukkia 5 aletaan pyorittåå samalla, kun ohjaus-vaunua 10 siirretaan kierråtystukin 5 pituussuunnassa. Hakaslangan 12 tullessa betoniteråksen 2 kohdalle se hitsataan kiinni hitsauspaan 14 avulla, jolloin lopputuloksena 25 on tukevasti kokoonpantu betoniraudoite-elementti. Raudoitteen tultua tehdyksi valmiiksi hakaslanka 12 katkais-taan, tukilaakeri 7, joka on korkeussuunnassa paikalleen nostettavissa ja alaslaskettaessa lasketaan ala-asentoon ja valmis raudoite siirretaan rullapoytåå 8 pitkin pois 30 kierråtystukin ympåriltå, jonka jalkeen sama tyovaihe toistetaan uudelleen. Hakaslankaa 12 voidaan kiertåå rau-doitteeseen koko sen pituudelle tai esimerkiksi påtkittåin eri kohtiin, kunhan sen måårå ja sijainti vastaa raudoit-teelle asetettuja lujuus- ja jåykkyysvaatimuksia.During the production of the concrete reinforcement, the pre-cut concrete steel 2 is transferred by a transfer device 4 to the rotating supports 5 to the holders described in connection with Figures 3-9, after which the hook-and-groove 12 is welded to the first reinforcing steel 2 and the circulating support 5 begins to rotate is moved in the longitudinal direction of the recirculation support 5. When the hook wire 12 comes to the reinforcing steel 2, it is welded to the welding head 14, whereby the end result 25 is a firmly assembled concrete reinforcement element. When the reinforcement is completed, the hook wire 12 is cut, the support bearing 7, which can be raised in height and lowered, is lowered and the finished reinforcement is moved along the roller table 8 out of the circumferential support 30, after which the same work step is repeated. The hook wire 12 can be twisted into the reinforcement along its entire length or, for example, at various points, as long as its amount and location meet the strength and stiffness requirements set for the reinforcement.

Kierråtystukin 5 muodostaa vaipan 16 muodosta-ma palkkimainen kotelo, jonka keskellå on pyoritysakseli 5 17, jonka ympåri kierråtystukkia 5 pyoritetåån pyoritys- koneiston 6 avulla. Edelleen kierråtystukkiin kuuluu akselin 17 ymparillå oleva holkkimainen akseli 18, johon on kiinnitetty keskiolaippoja 19. Edelleen kierråtystukissa 5 on ohjainputkia 20, joiden låpi kulkevasti on keskiolaip-10 poihin 19 kiinnitetty tukivarsia 21. Tukivarsien 21 påisså on betoniteråksiå 2 vårten koteion vaipan 16 suhteen liik-kuvia betoniteråsuran 22 muodostavia tukielimiå, joihin valinnan mukaan asetetaan betoniteråksiå 2.

The recirculation support 5 is formed by a beam-like housing formed by a jacket 16, in the middle of which there is a rotation shaft 5 17, around which the recirculation support 5 is rotated by means of a rotation mechanism 6. The recirculating support further comprises a sleeve-like shaft 18 around the shaft 17, to which the central flanges 19 are attached. Further, the recirculating support 5 has guide tubes 20 through which support arms 21 are attached to the central flange 10 tracks 19. At the ends of the support arms 21 there are reinforcements pictures of the support members forming the concrete steel groove 22, on which the reinforcing bars 2 are optionally placed. Further, at the appropriate intervals, the fastening members 23 described in connection with Figures 8a and 8b are mounted at suitable intervals in the recirculating supports 5, holding the rebar 2

Siirrettåesså betonirauta 2 telineeltå 1 kierråtystukille se lasketaan kiinnitysuran 22 kohdalle, jonka jålkeen se kiinnitetåån 25 paikalleen esimerkiksi myohemmin esitettåvållå tavalla, kierråtystukki 5 kåånnetåån eteenpåin niin, ettå seuraava betoniteråksen kiinnitysura 22 on kohdallaan ja uusi be-toniterås siirretåån siihen ja nåin jatketaan, kunnes kaikki tarvittavat betoniteråkset 2 ovat paikallaan. Kun 30 betoniraudoite on hakaslangan kiinnityksen jålkeen valmis, pyoritetåån holkkimaista akselia 18 vastakkaiseen suun-taan, jolloin se vetåå kiinnitysuraelimet sisåånpåin, jol-loin kiinnitysurien ja raudoitteen vålille syntyy vålys. Rullapoytå 8, joka on sinånså tunnetulla tavalla nostetta-35 vissa ja laskettavissa korkeussuunnassa, nostetaan ylos, l· 90833 7 kunnes se kannattaa kierråtystukin ja raudoitteen, jonka jålkeen laakeri 7 lasketaan alas ja betoniraudoite voidaan vetåa kierråtystukin 5 paåltå rullapoytåå 8 pitkin pois. Tåman jalkeen laakeri 7 nostetaan takaisin kannattamaan 5 kierråtystukkia 5, rullapoytå 8 lasketaan ala-asentoonsa ja toiminta toistuu.When starting to manufacture reinforcement, the sleeve shaft 18 is rotated around the shaft 17 so that the central plates 19 20 push the support arms 21 outwards and thus the fastening grooves of the reinforcing bars are obtained outwards according to the dimensioning of the concrete reinforcement made from the shaft 18. When moving the rebar 2 from the stand 1 to the recirculation support, it is lowered to the fixing groove 22, after which it is fixed 25 in place, for example as shown later, the recycling support 5 is turned forward until reinforcing bars 2 are in place. When the concrete reinforcement 30 is completed after the fastening of the hooked wire, the sleeve-like shaft 18 is rotated in the opposite direction, whereby it pulls the fastening grooves inwards, whereby a clearance is created between the fastening grooves and the reinforcement. The roller table 8, which is raised and lowered in the height direction in a manner known per se, is raised until it supports the recirculation support and reinforcement, after which the bearing 7 is lowered and the concrete reinforcement can be pulled off the recirculation support 5 from the roller support 8. After this, the bearing 7 is lifted back to support the 5 recirculation logs 5, the roller table 8 is lowered to its lower position and the operation is repeated.

Kuviossa 5 on esitetty erilaisia raudoitemalleja, joita voidaan valmistaa kuvioiden 3 ja 4 esittåmån kierråtystukin 5 avulla. Raudoitemalleissa on olennaisena erona 10 betoniteråsten måårå, joka riippuu raudoitteen kåyttotar-koituksesta.Figure 5 shows various reinforcement models that can be manufactured by means of the recycling support 5 shown in Figures 3 and 4. The essential difference in the reinforcement models is the number of rebar 10, which depends on the intended use of the reinforcement.

Kuviossa 6 on poikkileikkauksena esitetty eras toi-nen kierråtystukin sovellutusmuoto, jossa kierråtystukki 5 on muodostettu erillisistå vaipallisista lohkoista 16a -15 16d.

Each block has different reinforcements for one or more fastening grooves for the reinforcing bars, in which case the block itself acts as a fastening groove member. In this case, when rotating the sleeve shaft 18 around the shaft 17, the blocks move completely out of the shaft 17 and inwards, respectively. In the model shown, the number and location of the steels can be selected in different ways, for example as shown in Figure 7.

Kuvioissa 8a ja 8b on esitetty erås sovellutusmuoto betoniteråsten pitimeksi 23, jolla betoniteråkset saadaan 25 pysymåån paikoillaan kierråtystukin 5 pyorimisesta huoli-matta silloin, kun hakaslanka 12 ei vielå sido niitå toi-siinsa. Kuviossa 8a on betoniteråksen 2 suunnassa katsot-tuna kahdella leualla 24a ja 24b varustettu pihti.

In this case, for example, a particular reinforcement model can be manufactured for the first time by manual control while being transferred to the computer's memory, after which the remaining reinforcements to be manufactured in the same way can be produced automatically under computer control. With the method and apparatus according to the invention, reinforcements of different shapes can be produced simply and efficiently simply by making a number of reinforcing bars or, if necessary, by changing the recycled log to a different cross-section. The method and equipment can be used to produce 30 square, rectangular or other polygonal reinforcements as well as round reinforcements. The method and equipment make heavy and cumbersome work quick and simple, as well as largely automatic, in which case the instructor is mainly needed to monitor the operation and to ensure the sufficiency of the raw material and to change the model 11 90833 9 when the reinforcement models change. The invention is in no way bound to the exemplary embodiments presented above, but can be applied in several different ways. The fastening grooves of the reinforcing bars can be constructed in different ways, either as separate movable groove members or as movable blocks or block parts. The transfer mechanism can be implemented in various ways, for example by means of eccentrics or other similar structures. Reinforcing steel holders can be constructed in a number of different ways, and instead of mechanical holders, magnetic, pneumatic or other suitable holding solutions can also be used. Mechanical holders can be implemented in several different ways, for example by using spring solutions or something similar. With the method and device 15 according to the invention, it is of course also possible to produce reinforcements by placing steel longer than the required reinforcement, such as twice the length of steel to be produced twice, and producing one reinforcement, which is then cut separately to the desired length. This or other similar embodiment in which the length of the reinforcement is changed after manufacture is also within the scope of the invention, since in any case after the manufacturing step there is essentially a ready-to-use reinforcement as such.
