La presente invenzione ha per oggetto un attrezzo per il fissaggio di scatole di installazione elettrica alle pareti delle forme per la produzione di pannelli prefabbricati per costruzioni edili, e in particolare alle forme a pareti verticali.The present invention relates to a tool for fixing electrical installation boxes to the walls of molds for the production of prefabricated panels for building constructions, and in particular to molds with vertical walls. È noto che nelle forme verticali il getto di cemento investe lateralmente le scatole fissate alle pareti, tendendo a spostarle dalla loro posizione o addirittura ad asportarle, a causa della massa e della velocità acquistata dal cemento stesso durante la gettata.It is known that in vertical forms the concrete casting hits the boxes fixed to the walls laterally, tending to move them from their position or even to remove them, due to the mass and speed acquired by the concrete itself during the casting. Fino ad ora il problema è stato risolto utilizzando organi di reazione che, a forma chiusa, poggiano sulla parete opposta ed esercitano sulla scatola una spinta che la mantiene in posto. Questi organi presentano il doppio inconveniente di un maggior impiego di manodopera, per il loro fissaggio, uno spreco di materiale e un maggior costo, perché essi sono elementi a perdere, in quanto rimangono annegati nel getto di cemento.Up to now the problem has been solved by using reaction members which, when closed, rest on the opposite wall and exert a push on the box which keeps it in place. These members have the double drawback of a greater use of manpower, for their fastening, a waste of material and a higher cost, because they are disposable elements, as they remain embedded in the concrete casting. La presente invenzione ha lo scopo di eliminare questi inconvenienti.The present invention has the object of eliminating these drawbacks. L'attrezzo in accordo con l'invenzione consiste in un corpo di lamiera cavo, delimitato perifericamente da un gradino, che, da una parte, è destinato a poggiare contro la parete della forma, e dall'altra parte, a costituire l'appoggio dei bordi dell'imboccatura della scatola da fissare, la parte convessa di detto attrezzo entrando all'interno di detta scatola ed essendo dotata di incavi atti ad evitare interferenze con organi della scatola sporgenti all'interno di essa, tale attrezzo essendo dotato di due manicotti sporgenti nella sua parte cava, ma non oltre il piano del gradino periferico, per permettere il passaggio di mezzi di fissaggio, alla parete, prima di innestare su di esso la scatola da fissare, mezzi di s incastro essendo previsti per bloccare la scatola su detto attrezzo onde essa non venga spostata dal getto di cemento.The tool according to the invention consists of a hollow sheet metal body, peripherally delimited by a step, which, on the one hand, is intended to rest against the wall of the form, and on the other hand, to form the support of the edges of the mouth of the box to be fixed, the convex part of said tool entering inside said box and being provided with recesses suitable to avoid interference with members of the box protruding inside it, this tool being equipped with two sleeves protruding in its hollow part, but not beyond the plane of the peripheral step, to allow the passage of fixing means to the wall, before engaging the box to be fixed thereon, release means being provided for blocking the box on said tool to prevent it from being moved by the concrete casting. L'oggetto dell'invenzione a titolo di esempio non limitativo di realizzazione, è mostrato negli annessi disegni, in cui:The object of the invention by way of non-limiting example of embodiment is shown in the attached drawings, in which: — la fig. 1 è una vista assonometrica dell'attrezzo;— the fig. 1 is an axonometric view of the implement; io — la fig. 2 mostra i vari organi di fissaggio in posizione separata;I — fig. 2 shows the various fastening members in separate position; — la fig. 3, mostra in sezione mediana, l'assieme degli organi montati sulla parete di una forma.— the fig. 3, shows in median section, the assembly of the members mounted on the wall of a form. Come mostrato nelle dette figure, l'attrezzo 1 dell'inven-15 zione è costituito da un corpo in lamiera cavo delimitato da un gradino 2 periferico sviluppantesi su un piano e che, da una parte, è destinato a poggiare sul piano della parete della forma e, dall'altra parte, cioè quella mostrata in fig. 1, a fungere da appoggio a tenuta del bordo 3 di una scatola 4 20 da fissare.As shown in said figures, the tool 1 of the invention consists of a hollow sheet metal body delimited by a peripheral step 2 extending on a plane and which, on the one hand, is intended to rest on the plane of the wall of the shape and, on the other hand, i.e. the one shown in fig. 1, to act as a sealing support for the edge 3 of a box 4 20 to be fixed. L'attrezzo 1 è cavo e presenta la parte convessa verso la scatola e tale parte convessa è dotata di incavi 5 e 6 opposti destinati ad alloggiare le sporgenze interne rispettivamente 7 e 8 della scatola, previste per l'impegno di viti soste-25 nenti gli organi di supporto delle apparecchiature elettriche.The tool 1 is hollow and has the convex part towards the box and this convex part is provided with opposite recesses 5 and 6 intended to house the internal protrusions 7 and 8 respectively of the box, provided for the engagement of supporting screws the support members of the electrical equipment. L'attrezzo 1 è dotato di due manicotti 9 e 10 dotati di fori passanti diretti perpendicolarmente al piano del gradino 2, detti manicotti essendo sporgenti all'interno della parte concava dell'attrezzo e terminanti con risvolti 9' e 10' che 30 non oltrepassano il piano del gradino 2.The tool 1 is equipped with two sleeves 9 and 10 provided with through holes directed perpendicularly to the plane of the step 2, said sleeves projecting inside the concave part of the tool and ending with turn-ups 9' and 10' which 30 do not go beyond the step plane 2. Su due pareti opposte, l'attrezzo 1 presenta due fenditure 11 nelle quali sono destinate ad entrare due linguette 12 presentate dalla scatola e sporgenti all'interno da due pareti opposte di questa, in modo che, quando la scatola viene in-35 nestata sull'attrezzo 1, portando il bordo 3 a poggiare sul gradino 2, le linguette 12 penetrano a scatto nelle fenditure 11 bloccando la scatola stessa.On two opposite walls, the tool 1 has two slits 11 into which two tabs 12 presented by the box and protruding inside from two opposite walls of this are intended to enter, so that, when the box is engaged on the When the tool 1 brings the edge 3 to rest on the step 2, the tabs 12 snap into the slits 11 blocking the box itself. Come mostrato nelle figg. 2 e 3, per il fissaggio, l'attrezzo 1 viene disposto contro la parete 13 di una forma ed è 40 ivi fissato mediante chiodi passanti attraverso i manicotti 9 e 10.As shown in FIGS. 2 and 3, for fixing, the tool 1 is placed against the wall 13 of a form and is 40 fixed there by means of nails passing through the sleeves 9 and 10. Nel caso di pareti in legno, possono essere usati chiodi a penetrazione o viti. Nel caso, invece, che la parete, indifferentemente in legno o in metallo, abbia fori predisposti 45 14 e 15, l'attrezzo 1 viene fissato di preferenza mediante chiodi ad espansione 16 e 17, di per se noti, che favoriscono la speditezza del lavoro.In the case of wooden walls, penetration nails or screws can be used. If, on the other hand, the wall, either in wood or in metal, has prearranged holes 45 14 and 15, the tool 1 is preferably fixed by means of expansion nails 16 and 17, known per se, which favor the speed of the Work. Una volta fissato l'attrezzo 1, su di esso si applica la scatola nel modo sopra detto, dopodiché si può chiudere 50 la forma ed eseguire il getto.Once the tool 1 has been fixed, the box is applied to it in the manner described above, after which the mold can be closed 50 and cast. Al momento della sformatura del pannello, la trazione esercitata dalla parete in fase di apertura è sufficiente a causare la rottura delle due linguette 12, per cui assieme alla parete viene asportato l'attrezzo che rimane in posizione per 55 un successivo getto, mentre la scatola rimane incorporata nel pannello prefabbricato.When demoulding the panel, the traction exerted by the wall during the opening phase is sufficient to cause the breakage of the two tabs 12, whereby the tool is removed together with the wall, which remains in position for 55 a subsequent casting, while the box remains incorporated in the prefabricated panel. 2 fogli disegni2 drawing sheets
