Description

  

      Appareil    pour le levage des matériaux de construction.         L'invention,    a pour objet un     appareil    pour  le levage des.     matériaux    de     construction,     notamment pour les travaux -de drainage. Il  est destiné à     faciliter    la     manutention    des  matériaux, en     particulier    des     canaux    en béton       utilisés.    pour     établir    des regards de     visites          (cheminées)    sur collecteurs.

   La manutention  de canaux d'un poids     relativement        élevé    est  facilitée     du:    fait que -des attaches peu sûres,       ,gênantes.    et     coûteuses    sont     évitées,    et l'emboî  tage des canaux peut. se faire directement,  d'où économie     -de        main-,d'oeuvre.     



  Le     dessin    ci-joint montre, à titre d'exem  ple, une forme d'exécution .de -cet     appareil.     La     fig.    1 est une vue -de face et la     fig.    2  est une vue     par-dessus.     



  Deux     flasques   <I>A et A'</I> reliés entre eux  par des     entretoises        M-H'-M"        forment    un  bâti qui     porte    à     ses.    deux     extrémités        des        mar-          daches   <I>P et</I> P' respectivement dont la partie  extérieure est .striée afin de présenter un  appui     rugueux;

          lesdites        mordaches    P et<B>'</B> de  forme     excentrique    pivotent     sur    des. tourillons  C et C' respectivement -et se     prolongent    cha  cune par l'un des deux bras -de levier B et B'  dont les,     extrémités.    sont reliées au moyen de       tourillons    D et D' à des leviers E et E';

       ces          leviers    E et<B>E</B> se     rejoignent    à leur     extrémité          supérieure    par un     tourillon    H fixé .dans une       pièce    I     qui        comporte    une boucle pour l'atta  che du     eârble    du moufle de levage.

   Par le jeu  des leviers, la     traction        @du        câble    sur la     bouille    I  oblige les     mordaches   <I>P et P'</I> à     pivoter    sur les  tourillons C et C' et 'leur forme excentrique         produit    un     coincement    contre la paroi inté  rieure du canal, et cela d'autant     plus    puis  samment que le     poids    de     ce        4ernîer    est plus  grand.

   Les     portées        d'emboîtement        restent     libres et peuvent en     conoéquence    permettre  de juxtaposer les canaux sans     difficûlté.  



      Device for lifting construction materials. The invention relates to an apparatus for lifting. building materials, especially for drainage works. It is intended to facilitate the handling of materials, in particular the concrete channels used. to establish inspection manholes (chimneys) on collectors.

   The handling of channels of a relatively high weight is facilitated by: the fact that -secure fasteners,, annoying. and expensive are avoided, and the fitting of the channels can. be done directly, hence saving - of labor - of labor.



  The accompanying drawing shows, by way of example, an embodiment of this apparatus. Fig. 1 is a front view and FIG. 2 is a top view.



  Two flanges <I> A and A '</I> interconnected by spacers M-H'-M "form a frame which carries at its two ends brackets <I> P and </I> P 'respectively whose outer part is .striée in order to present a rough support;

          said jaws P and <B> '</B> of eccentric shape pivot on. journals C and C 'respectively -and are extended each by one of the two lever arms B and B' whose ends. are connected by means of pins D and D 'to levers E and E';

       these levers E and <B> E </B> are joined at their upper end by a pin H fixed. in a part I which has a loop for attaching the eârble of the lifting block.

   By the play of the levers, the traction @ of the cable on the nozzle I forces the jaws <I> P and P '</I> to pivot on the pins C and C' and their eccentric shape produces a wedging against the internal wall. higher of the canal, and all the more so as the weight of this last is greater.

   The interlocking spans remain free and can therefore make it possible to juxtapose the channels without difficulty.
