Den foreliggende opfindelse angår en videreudvikling af den i patent nr. 140.972 omhandlede maskine til støbning af betonbyggeelementer bestående af indtil fire langs en kant monolitisk sammenhængende, etagehøje 5 vægpartier og et overliggende, med vægpartierne monolitisk sammenhængende dækparti og omfattende fire formparter, der hver har tre på hinanden vinkelrette formflader, som danner et udvendigt hjørne med to lodrette sider og en vandret overside, hvilke formparter er an-10 bragt på et fælles fundament og i forhold til dette er bevægelige imellem en lukket støbestilling, i hvilken de over for hinanden stående lodrette formflader af et par naboformparter danner sider i et vægpartistøberum og slutter mod en af fundamentet båret formbund for det 15 pågældende støberum, og en åben stilling, i hvilken de fire formparter er fjernet fra hinanden og samtidig sænket i forhold til formbunden ved en bevægelse, der fra den lukkede stilling er sammensat af en indledende frigørelsesbevægelse parallel med en linie gennem hjør-20 nepunktet og en påfølgende egentlig åbnebevægelse i hovedsagelig vandret retning, fortrinsvis parallel med vinkelhalveringsplanet mellem de lodrette formflader.BACKGROUND OF THE INVENTION The present invention relates to a further development of the machine described in Patent No. 140,972 for casting of concrete building elements consisting of up to four along one edge, monolithically continuous, high-floor 5 wall portions and an overlying, with the wall portions monolithically continuous cover portion and comprising four molding parts, each having three rectangular shaped faces forming an outer corner with two vertical sides and a horizontal top side, which mold members are arranged on a common foundation and are movable therebetween in a closed casting position in which they face each other vertically mold surfaces of a pair of neighboring moldings form sides of a wall molding compartment and terminate against a mold base supported for the molding in question, and an open position in which the four moldings are removed from each other and simultaneously lowered relative to the mold bottom by a movement which from the closed position is composed of an initial release movement p arallel with a line through the corner point and a subsequent actual opening movement in a substantially horizontal direction, preferably parallel to the angular half plane between the vertical mold faces.

En sådan maskine er ifølge den foreliggende opfindelse ejendommelig ved, at formparterne hver er 25 kørbare ved hjælp af på formpartens bærende konstruktion lejrede hjul og på fundamentet anbragte skinner i hovedsagelig vandret retning fra den åbne stilling i retning mod den lukkede støbestilling hovedsagelig i retning parallel med vinkelhalveringsplanet mellem de 30 enkelte formparters lodrette formflader, hvilke skinner har et afsluttende stigende parti svarende til den sidste del af den tilhørende formparts lukkebevægelse.Such a machine according to the present invention is characterized in that the molding parts are each operable by means of wheels mounted on the bearing structure of the molding and rails mounted on the foundation in a substantially horizontal direction from the open position towards the closed casting position mainly in parallel with the angular half-plane between the vertical mold faces of the 30 individual moldings, which rails have a final rising portion corresponding to the last part of the corresponding molding's closing movement.

Herved muliggøres en meget enkel og robust udformning af formparternes understøtnings- og bevægel-35 sesmekanisme, som er billig at fremstille, let at vedli- 2This enables a very simple and robust design of the molding support and movement mechanism, which is inexpensive to manufacture, easy to maintain.

Til tilvejebringelse af den sidste del af lukkebevægelsen og den første del af åbnebevægelsen har hver 5 formpart fortrinsvis ifølge opfindelsen en af en hydraulisk cylinder påvirket knæstangsmekanisme/ hvis ene ende er hængslet til formpartens bærende konstruktion, og hvis anden ende er indrettet til ved overgangen til den afsluttende del af lukkebevægelsen at komme i anlæg 10 mod et fast vederlag på maskinens fundament.In order to provide the last part of the closing movement and the first part of the open movement, each mold part preferably according to the invention has a hydraulic cylinder actuated by a hydraulic cylinder / one end of which is hinged to the bearing part of the mold part and the other end is arranged at the transition to it. final part of the closing movement to arrive in plant 10 for a fixed fee on the machine's foundation.

Forbindelsen mellem dette vederlag og den fri ende af knæstangsmekanismen er hensigtsmæssigt ifølge opfindelsen indrettet til at optage både trækkræfter og trykkræfter fra knæstangsmekanismen, hvorved det sikres, 15 at løsrivelsen af formparten fra det færdigstøbte element kan udføres med hele den kraft, som den hydrauliske cylinder kan udøve gennem knæstangsmekanismen.Conveniently, according to the invention, the connection between this consideration and the free end of the knee bar mechanism is adapted to absorb both tensile and compressive forces from the knee bar mechanism, thereby ensuring that the release of the mold part from the finished cast can be accomplished with all the force that the hydraulic cylinder can provide. exercise through the knee-bar mechanism.

Opfindelsen er anskueliggjort på tegningen, på hvilken 20 fig. 1 på tilsvarende måde som fig. 4 i hovedpa tentet viser et sidebillede af en enkelt formpart med tilhørende bevægemekanisme, fig. 2 det i fig. 1 viste set fraoven, fig. 3 i større målestok og mere detaljeret form-25 partens kørehjul med tilhørende bevægemekanisme i køre-stilling, fig. 4 det i fig. 3 viste under begyndende lukkebevægelse, og fig. 5 det i fig. 3 viste i den sluttelige lukke-30 stilling.The invention is illustrated in the drawing, in which FIG. 1 in a manner similar to FIG. 4 of the main patent shows a side view of a single molding part with associated movement mechanism; FIG. 2 shows the embodiment of FIG. 1 from above; FIG. 3 on a larger scale and in more detail the driving wheels of the molding party with associated movement mechanism in the driving position; FIG. 4 shows the embodiment of FIG. 3 during the initial closing movement, and FIG. 5 shows the embodiment of FIG. 3 in the final closing position.

På tegningen betegner 2 ligesom i hovedpatentets tegning en enkelt af maskinens formparter bestående af to lodrette formflader 6 og 7 og en vandret formflade 8, der tilsammen danner et retvinklet hjørne, og som er 35 fastgjort på en ikke nærmere vist bærekonstruktion af tilstrækkelig styrke og stivhed.In the drawing, as in the main patent drawing, 2 denotes a single of the machine's molding parts consisting of two vertical molding surfaces 6 and 7 and a horizontal molding surface 8, which together form a right-angled corner, and which are fixed to a carrier structure not shown in sufficient detail and stiffness. .

Den viste formpart bæres gennem sin bærekonstruktion af tre hjul 26, hvis akser er vinkelrette på vinkelhalveringsplanet for den af de lodrette formflader 6 og 7 indesluttede rette vinkel, og som kan køre på 5 skinner 27, der på ikke nærmere vist måde er fastgjort til maskinens ikke viste fundament ved hjælp af bolte 39.The molded part shown is supported by its support structure of three wheels 26, the axes of which are perpendicular to the angular half plane of the right angle enclosed by the vertical mold surfaces 6 and 7, and which can run on 5 rails 27, which are not attached to the machine's details. not shown foundation using bolts 39.

Formparten 2 bevæges manuelt i vandret retning kørende på disse skinner fra en åben stilling, i hvilken formparterne er tilstrækkelig langt fjernet fra 10 hinanden til, at de nødvendige arbejdsoperationer på formfladernes aktive overflader kan foretages, ind imod den lukkede endestilling, i hvilken formfladen er vist i fig. 1 og 5. På det sidste stykke af lukkebevægelsen kører hjulene 26 op ad kileformede flader 28 på 15 skinnerne 27, hvilke flader kan indstilles nøjagtigt i den ønskede stilling til regulering af formpartens endelige højdeindstilling ved hjælp af indstillingsbolte 40, idet endestop 29 herunder begrænser bevægelsen af hjulene 26.The mold part 2 is moved manually in a horizontal direction on these rails from an open position in which the mold parts are sufficiently far apart from each other for the necessary working operations on the active surfaces of the mold surfaces to be carried out towards the closed end position in which the mold surface is shown. in FIG. 1 and 5. On the last piece of the closing movement, the wheels 26 drive up wedge-shaped surfaces 28 of the rails 27, which surfaces can be precisely adjusted in the desired position for controlling the final height adjustment of the mold part by means of adjusting bolts 40, the end stop 29 including restricting movement. of the wheels 26.

20 Den sidste del af lukkebevægelsen udføres ved hjælp af en hydraulisk cylinder 30, der er hængslet drejeligt om en tap 31, som er i fast forbindelse med formpartens bærende konstruktion og har fat i et knæled 34 i en knæstang 32, 33, hvis ene ende er lejret 25 svingbart om det tilhørende hjul 26's akse, medens den anden ende normalt er fri og ender i en cylindrisk tværstang 35.The last part of the closing movement is carried out by means of a hydraulic cylinder 30 hinged pivotally about a pin 31 which is in fixed connection with the supporting structure of the mold part and which grips a knee joint 34 in a knee bar 32, 33, one end of which the bearing 25 is pivotable about the axis of the associated wheel 26, while the other end is normally free and ends in a cylindrical transverse rod 35.

Når formparten er blevet skudt ind i den i fig. 3 viste stilling på vej til lukning, åbnes der for hydrau-30 lisk trykmiddel til den hydrauliske cylinder 30, som derved forlænges og trykker knæstangen 32, 33 ned til den i fig. 4 viste stilling, hvor tværstangen 35 finder anlæg i et vederlag 36, der er i fast forbindelse med skinnerne 27. Fortsat forlængelse af den hydrau-35 liske cylinder 30 medfører udretning af knæstangen 32, 4When the mold part has been shot into the one shown in FIG. 3, hydraulic pressure means are opened for the hydraulic cylinder 30, which is then extended and depresses the knee rod 32, 33 to the position shown in FIG. 4, where the transverse rod 35 finds abutment in a retainer 36 which is fixedly connected to the rails 27. Continued extension of the hydraulic cylinder 30 results in the straightening of the knee rod 32, 4.

33 som vist i fig. 5, hvorved hjulene 26 drives op ad de kileformede skråflader 28 og løfter formparten skråt opad til den endelige støbestilling/ i hvilken den er låst ved udretningen af knæleddet 32, 33.33 as shown in FIG. 5, whereby the wheels 26 are driven up the wedge-shaped oblique surfaces 28 and lift the mold part obliquely upwards to the final casting position / in which it is locked by the straightening of the knee joint 32, 33.

5 Samtidig med udretningen af knæstangen 32, 33 og den dermed forbundne svingning af knæstangdelen 32, føres en holdeplade 37, der er fastsvejst til tværstangen 35 og armen 32, ned bag et modsat rettet vederlag 38, så at formparten er låst mod bevægelse i begge 10 retninger, og derudover låses formparten i støbestilling ved hjælp af endestoppene 29, som forhindrer formparten i at vippe opad omkring, gennem hjulene gående understøtningsakser .5 At the same time as the straightening of the knee bar 32, 33 and the associated oscillation of the knee bar part 32, a holding plate 37, which is welded to the cross bar 35 and the arm 32, is brought down behind an opposite directed support 38, so that the mold part is locked against movement in both In addition, the mold part is locked in casting position by the end stops 29, which prevent the mold part from tilting upwardly, through supporting axes passing through the wheels.

Efter støbning og tilstrækkelig hærdning af ele-15 mentet tilføres der hydraulisk trykvæske til forkortelse af cylinderen 30, hvorunder der sker en positiv fritrækning, dvs. en samtidig bevægelse af formfladerne 6, 7 og 8 bort fra elementets betonflader, af formparten fra det støbte element ved en skråt nedad gående be-20 vægelse som følge af indgrebet mellem pladen 37 og vederlaget 38, og når dette indgreb er ophævet ved svingning af knæstangsdelen 32, løftes knæstangen op til den i fig. 3 viste tilstand, hvorefter formparten manuelt kan bevæges til helt åben stilling.After casting and sufficient curing of the element, hydraulic pressure fluid is applied to shorten the cylinder 30, during which a positive friction, i.e. a simultaneous movement of the mold surfaces 6, 7 and 8 away from the concrete surfaces of the element, of the mold part from the molded element by an inclined downward movement as a result of the engagement between the plate 37 and the backing 38, and when this engagement is canceled by pivoting knee bar portion 32, the knee bar is raised to the one shown in FIG. 3, after which the mold part can be moved manually to fully open position.

25 Det viste knæstangssystem 32, 33 med drivcylin der 30 kan forefindes ved alle formpartens kørehjul, men ved passende dimensionering er det tilstrækkeligt, at et sådant system findes ved et enkelt kørehjul, fortrinsvis som vist ved det, der ligger nærmest ved den 30 lodrette kant mellem de lodrette formflader 6 og 7.25 The shown bar system 32, 33 with drive cylin 30 which can be found at all the drive wheels of the molding, but with appropriate dimensioning it is sufficient that such a system is found at a single drive wheel, preferably as shown at that closest to the vertical edge. between the vertical mold surfaces 6 and 7.

Der kan i stedet for den beskrevne hydrauliske cylinder 30 anvendes en pneumatisk cylinder eller en skruedonkraft, og der kan findes indstillelige stop til begrænsning af lukkebevægelsens sidste del til nøjagtig 35 fastlæggelse af beliggenheden af formpartens formflader i støbestillingen.Instead of the described hydraulic cylinder 30, a pneumatic cylinder or a screwdriver may be used, and adjustable stops may be provided to limit the last part of the closing movement to accurately determine the location of the mold surfaces of the molding part in the casting position.
