Moulding unit for girder construction by means of quick-assembly systems

Abstract

The invention relates to a unit that comprises a closing piece arranged on a horizontal surface onto which side panels are secured, for which purpose the closing piece has side perforations arranged longitudinally and in line with projections that the side panels have on their lower edge. The side panels are vertically secured onto the closing piece via clips or the like secured onto the closing pieces. Thanks to the structural features of the parts and their engaging design, an assembly is obtained which is easy to assemble and dismantle, allowing girders to be built directly on site, as well as allowing the removal of forms from girders with complex geometries (holes, section reductions, etc.).

1 . Moulding unit for girder construction by means of quick-assembly systems comprising:
 a set of closing pieces ( 2 ) arranged on the horizontal surface   a set of side panels ( 4 ) fitted and secured onto the closing pieces by fitting the merlon-like projections that the side panels have on their lower edge ( 4 . 2 ) onto the perforations ( 2 . 1 ) and ( 2 . 2 ) arranged longitudinally along the side edges of the closing pieces ( 2 ), the side panels ( 4 ) are vertically secured onto the closing pieces ( 2 ) via clips or the like   characterized in that the merlon-like projections ( 4 . 2 ) have a rounded edge ( 4 . 3 ) on their inner face which coincides with the geometry of the longitudinal perforations ( 2 . 1 ) and ( 2 . 2 ).   
     
     
         2 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 1 , characterized in that the closing piece ( 2 ) has a longitudinal central space ( 2 . 3 ) enclosed by the side edges in which display the longitudinal perforations ( 2 . 1 ) and ( 2 . 2 ). 
     
     
         3 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 1 , characterized in that the closing piece ( 2 ) has on its ends has an auxiliary joining means ( 2 . 4 ) and ( 2 . 5 ) which enable the lining up of the closing pieces. 
     
     
         4 . (canceled) 
     
     
         5 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 1 , characterized in that the side panels ( 4 ) have some binding projections ( 4 . 1 ) face to face which fit into each other. 
     
     
         6 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 1 , characterized in that the side panels ( 4 ), have a supporting piece ( 6 ) on their upper edge that holds upper closing panels ( 5 ). 
     
     
         7 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 6 , characterized in that the supporting piece ( 6 ) is continuous piece ( 6 . 1 ). 
     
     
         8 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 1 , characterized in that the horizontal surface where the closing pieces ( 2 ) are placed may be either a continuous panel that holds the closing pieces ( 2 ) or longitudinal support placed one after another which hold the closing pieces ( 2 ) while independent panels are placed between them. 
     
     
         9 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 1 , characterized in that the closing pieces ( 2 ) and the side panels ( 4 ) are fixed to a same frame. 
     
     
         10 . The moulding unit for girder construction by means of quick-assembly systems according to  claim 9 , characterized in that the piece that constitute the frame, where the panels and the closing pieces ( 2 ) are fixed, are fitted together by means of knuckle joint paths ( 8 ).
