Beveiliging voor hijsklem voor bouwelementen.Protection for lifting clamp for building elements.
De uitvinding betreft een voorziening aan hijsklemmen voor bouwelementen. De voorziening voorkomt dat blokken of stenen uit de klem kunnen vallen, os Het is gebruikelijk om pakketten stenen, blokken kalkzandsteen en dergelijke met behulp van klemmen te laden en te lossen. Ook horizontaal verplaatsen van pakketten met behulp van hydraulische kranen wordt met deze klemmen gedaan.The invention relates to a provision of lifting clamps for building elements. The device prevents blocks or stones from falling out of the clamp. It is common practice to load and unload packages of stones, blocks of sand-lime brick and the like with the aid of clamps. Horizontal clamping of packages using hydraulic cranes is also done with these clamps.
In veel gevallen wordt bij hoogbouw kalkzandsteen verwerkt in scheidingswanden en dergelijke en moeten de kalkzandsteen elementen op grote hoogte gebracht worden. Kalkzandsteen is 10 gekenmerkt door gruis en stof waardoor de onderlinge wrijving tussen de elementen laag is. Hierdoor is de kans dat een element tussen de anderen uitglijdt groot. Het is dan ook nodig een beveiliging te hebben welke voorkomt dat een los element uit het pakket valt. Het probleem is dat de pakketten vanaf een vloer met de klem opgenomen moeten worden. Er is dan geen . gelegenheid om onder het pakket een beveiliging aan te brengen. In de practijk wordt nu eerst 15 het pakket een eindje opgehesen en wordt een stalen net onder de last door getrokken en vastgemaakt. Voor het neerzetten wordt dan eerst het net weer weggehaald en kan de last geplaatst worden.In many cases, in the case of high-rise buildings, sand-lime bricks are used in partitions and the like, and the sand-lime bricks have to be raised to great heights. Sand-lime bricks are characterized by grit and dust, so that the mutual friction between the elements is low. Because of this, the chance that an element slips between the others is high. It is therefore necessary to have a protection that prevents a loose element from falling out of the package. The problem is that the packages have to be picked up from a floor with the clamp. Then there is none. opportunity to provide security under the package. In practice, the package is now first slightly lifted and a steel just under the load is pulled through and fastened. To put it down, the net is first removed and the load can be placed.
De uitvinding betreft nu een inrichting waarbij na het vastklemmen en ophijsen van de last 20 vrijwel direct twee vangarmen een profiel onder de last brengen. Bij het neerzetten van de last wijken de vangarmen bij het kontact maken met de vloer en kan de klem zich openen. Er hoeft nu geen handeling meer uitgevoerd worden om de beveiliging te verwijderen.The invention now relates to a device in which, after clamping and lifting the load 20, two catching arms almost immediately bring a profile under the load. When the load is put down, the catch arms give way when contacting the floor and the clamp can open. No further action is required to remove the protection.
De uitvinding wordt besproken aan de hand van de tekening.The invention is discussed with reference to the drawing.

Fig. 1 toont een klem van het type dat gebruikt wordt om pakketten stenen of blokken te laden of lossen. De klem maakt gebruik van een schaarbeweging om het pakket bij het hijsen te klemmen tussen balken welke met rubber bekleed zijn.FIG. 1 shows a clamp of the type used to load or unload packages of bricks or blocks. The clamp uses a scissor movement to clamp the package during lifting between beams that are covered with rubber.
In fig. 2 is (1) de hijsklem. Aan scharnierpunten (2) zijn twee stel draaibare vangarmen (3, 4) 35 bevestigd. Vangarmen hebben ongeveer de vorm van een “L” en reiken over de last (7) en naar beneden. Aan vangarmen (3, 4) zijn profielen (5, 6) bevestigd, bijvoorbeeld door lassen. Profielen (5, 6) zijn net zo lang als de klembalken (9). Aan het eind van vangarmen (3, 4) zijn rollen (8) bevestigd welke onder profielen (5, 6) uitsteken. Aan de uiteinden van de klembalken ; f; ί ^ £ : 6 -2- (9) worden platen (10) aangebracht om te voorkomen dat blokken dwars uit klem (1) vallen. Steunplaten (11) beperken de beweging van vangarmen (3, 4) zodat bij het oppakken van de last (7) profielen (5,6) niet op de last stuiten.In Fig. 2 (1) is the lifting clamp. Two sets of rotating catch arms (3, 4) are attached to hinge points (2). Guard arms have the shape of an "L" and extend over the load (7) and down. Profiles (5, 6) are attached to catch arms (3, 4), for example by welding. Profiles (5, 6) are just as long as the clamping bars (9). At the end of catch arms (3, 4) rollers (8) are fixed which protrude under profiles (5, 6). At the ends of the clamp bars; f; Plates (10) are arranged to prevent blocks from falling transversely from the clamp (1). Support plates (11) limit the movement of catch arms (3, 4) so that when picking up the load (7) profiles (5,6) do not hit the load.
De hijsklem wordt na het openen van de klem bij het neerzetten van de last (7) met een (niet os getekend) palsysteem open gehouden. De vangarmen (3, 4) worden door steunplaten (11) open gehouden. Wanneer de klem met vangarmen (3, 4) over de last geplaatst wordt komen rollen (8) met de grond in aanraking en bij verder zakken van de klem vangarmen (3, 4) doen spreiden. Wanneer de klem op de last (7) aandrukt zal het palsysteem de klem lossen en zal bij het ophijsen aan oog (12) de klem sluiten en de last (7) opnemen. Bij het opnemen zullen rollen 10 het kontact met de grond verliezen en door hun gewicht bewegen vangarmen (3, 4) naar elkaar toe en zullen profielen (5, 6) zich onder de last bevinden. Als nu een steen losraakt zal die door profielen (5, 6) opgevangen worden. Platen (10) voorkomen dat de buitenste steen (13) dwars uit de klem valt. Bij het neerzetten van de last (7) zullen rollen (8) eerst kontact met de grond maken en vangarmen (3,4) spreiden en bij verder dalen opent de klem en het palsysteem houdt 15 de klem open en kan een nieuwe last (7) opgepakt worden.After opening the clamp, the hoisting clamp is kept open when the load (7) is put down with a (not shown) pawl system. The catch arms (3, 4) are held open by support plates (11). When the clamp with catch arms (3, 4) is placed over the load, rollers (8) come into contact with the ground and cause the catch arms (3, 4) to spread further when the clamp is lowered. When the clamp presses on the load (7), the retaining system will release the clamp and, when lifting on the eye (12), the clamp will close and receive the load (7). When picking up, rollers 10 will lose contact with the ground and their weight will move catch arms (3, 4) towards each other and profiles (5, 6) will be under the load. If a stone now comes loose, it will be caught by profiles (5, 6). Plates (10) prevent the outer brick (13) from falling across the clamp. When the load (7) is set down, rollers (8) will first make contact with the ground and spread catch arms (3, 4) and with further lowering the clamp opens and the retaining system keeps the clamp open and a new load (7) can ) being arrested.
Het is mogelijk dat het aanpassen van scharnierpunt (2) niet wenselijk is. Dan kan een apart scharnierpunt in de nabijheid van scharnierpunt (2) aangebracht worden. In verband met de ruimte is het wenselijk het horizontale deel (14) van vangarmen (3, 4) zo lang mogelijk te maken.It is possible that the adjustment of pivot point (2) is not desirable. A separate pivot point can then be provided in the vicinity of pivot point (2). In view of the space, it is desirable to make the horizontal part (14) of catch arms (3, 4) as long as possible.
20 De uitvinding kan ook als bouwpakket uitgevoerd worden en op bestaande klemmen aangebracht worden.The invention can also be embodied as a kit and applied to existing clamps.
Aan vangarmen (3, 4) kunnen verschillende beugels aangebracht worden welke dienen om de klem boven de last te brengen, deze zijn niet aangegeven.Different brackets can be attached to catch arms (3, 4) which serve to bring the clamp above the load, these are not indicated.
