Description

TITOLO: Sistema integrato di assorbimento delle forze per dispositivi di ancoraggio UNI EN 795/02 TITLE: Integrated system for absorbing forces for anchoring devices UNI EN 795/02

DESCRIZIONE: I dispositivi di ancoraggio sono supporti dove gli operatori si devono ancorare per essere trattenuti in caso di caduta dall'alto. DESCRIPTION: The anchoring devices are supports where the operators must anchor to be restrained in the event of a fall from a height.

In caso di caduta gli operatori ancorati con funi o cordini ai dispositivi generano delle forze (Tav. n.l , fig.l) che vengono trasmesse ai dispositivi di ancoraggio, tali forze possono essere di elevata entità e se non assorbite da dispositivi vari creare il distacco del dispositivo dal supporto. In the event of a fall, the operators anchored to the devices with ropes or cords generate forces (Table no. of the device from the holder.

Per assorbire queste forze ho sviluppato un sistema di assorbimento integrato per dispositivi di ancoraggio, evitando dì utilizzare assorbitori su funi o cordini. To absorb these forces I have developed an integrated absorption system for anchoring devices, avoiding the use of absorbers on ropes or lanyards.

Il sistema prevede l'assorbimento delle forze mediante la deformazione plastica o rottura di pareti metalliche(parete di resistenza) (Tav. n.l, Fig. n. 2b) da parte del perno di sfondamento che ruota attorno ad un perno di rotazione (Tav. n.l, Fig. n. 2a e 2b). The system provides for the absorption of forces through the plastic deformation or rupture of metal walls (resistance wall) (Table n.l, Fig. n.l, Fig. n.2a and 2b).

La distanza tra il perno di rotazione ed il perno di sfondamento e la consistenza delle pareti di resistenza fanno in modo di poter determinare lo sforzo necessario per l'inizio della fase di assorbimento e la quantità di forza che si vuole assorbire. The distance between the rotation pin and the breakout pin and the consistency of the resistance walls make it possible to determine the effort required for the start of the absorption phase and the amount of force to be absorbed.

Il vuoto oltre la parete di resistenza consente la possibilità di deformazione della parete di resistenza oltre a determinare l'angolo di rotazione (Tav. n.l, Fig. n. 2a e 2b). The void beyond the resistance wall allows the possibility of deformation of the resistance wall as well as determining the angle of rotation (Table n.l, Fig. N. 2a and 2b).

Il dispositivo di ancoraggio UNI EN 795/02 può essere composto sia da una piattina od un tubolare(asta) predisposta nella parte superiore per ancorare una fune od un cordino che produrranno delle forze ed alla base da piastre di ancoraggio da fissare al supporto; l'asta viene impacchettata tra due piastre di ancoraggio e bloccata con due bulloni di diametro e distanza tra loro variabile, i due bulloni diventano: uno perno di rotazione e l'altro perno di sfondamento come da esempio in Tav. n.l, Fig. n.3. The UNI EN 795/02 anchoring device can be composed of either a strap or a tubular (rod) arranged in the upper part to anchor a rope or cord that will produce forces and at the base by anchoring plates to be fixed to the support; the rod is packed between two anchoring plates and locked with two bolts of variable diameter and distance between them, the two bolts become: one rotation pin and the other breakout pin as shown in Table n.l, Fig.n .3.

Il dispositivo di ancoraggio sotto azione di determinate forze nella parte alta tende a ruotare su uno o più perni , ma la presenza di almeno 2 perni di cui almeno uno circondato da pareti di resistenza impedisce la rotazione rendendolo stabile (Tav.l: fig. 2a, tav.2: Fig. 4a e 5a) The anchoring device under the action of certain forces in the upper part tends to rotate on one or more pins, but the presence of at least 2 pins, at least one surrounded by resistance walls, prevents rotation making it stable (Table 1: fig. 2a , table 2: Fig. 4a and 5a)

Ma data la conformazione del foro contenente il perno di sfondamento che à ̈ circondato da una parete predeterminata(parete di resistenza) e da un vuoto predeterminato (angolo di rotazione), il dispositivo sotto l'azione di forze crescenti inizia a ruotare intorno ad un perno deformando o rompendo la parete di resistenza dopo il raggiungimento di una forza predeterminata (determinabile in base alla consistenza della parete di resistenza) (Tav.l: fig. 2b, tav.2: Fig. 4b e 5b). But given the conformation of the hole containing the breakout pin which is surrounded by a predetermined wall (resistance wall) and a predetermined void (angle of rotation), the device under the action of increasing forces begins to rotate around a pin deforming or breaking the resistance wall after reaching a predetermined force (which can be determined on the basis of the consistency of the resistance wall) (Table 1: Fig. 2b, Table 2: Fig. 4b and 5b).

Data la necessità di creare una rotazione dei perni con la deformazione plastica o rottura delle pareti di resistenza, perni di rotazione e sfondamento possono essere molteplici (Tav.2: fig.6) Given the need to create a rotation of the pins with the plastic deformation or breakage of the resistance walls, rotation and breakout pins can be multiple (Table 2: fig. 6)
