Method and means for constructing masonry walls

Abstract

A spacer/centering element includes on its periphery and/or close thereto, feet as zonal resting intermediaries for blocks pertaining to two superposed rows and, on one side thereof, first centering devices for engaging a hole in a block and, on the opposite side thereof, second centering offset from the first and arranged to engage a hole in an overlying block devices.

1 . A method for constructing a wall with prefabricated cementitious blocks in the form substantially of a right prism and provided with through lightening holes, which extend vertically in the constructed wall, in which the blocks are arranged offset from row to row, characterised by zonally resting, on the contour of the openings in the through holes of the blocks of one row, spacer/centering elements provided with first parts engaging in said holes for the purpose of centering said elements, on said one row there being superposed a second row of blocks to zonally rest on said spacer/centering elements, which are provided with second parts engaging in the holes of said second row for the purpose of centering the blocks of the second row, said operations involving said spacer/centering elements being repeated until at least a part of the wall has been erected, in the wall or its thus erected part there appearing interspaces (F) between the rows of blocks, which are sealed by injecting mortar thereinto.  
   
   
       2 . A spacer/centering element for implementing the method claimed in the preceding claim, characterised by comprising, preferably on its periphery and/or close thereto, feet ( 5 ) as zonal resting intermediaries for blocks ( 1 ) pertaining to two superposed rows and, on one side thereof, first centering means ( 6   a ), for engaging a hole ( 2 ,  3 ) in a block ( 1 ) and, on the opposite side thereof, second centering means ( 7   a ) offset from the first and arranged to engage a hole in an overlying block.  
   
   
       3 . A spacer/centering element as claimed in  claim 2 , wherein the first and second centering means ( 6   a,    6   b ) are skirts ( 6 ,  7 ) or parts thereof shaped in accordance with at least part of the profile of the hole ( 2 ,  3 ) of the block ( 1 ) in which they are to engage.  
   
   
       4 . A spacer/centering element as claimed in  claim 3 , wherein the feet ( 5 ) are pin shaped and are at least partly disposed along the outer contour of said element.  
   
   
       5 . A spacer/centering element as claimed in  claim 1 , wherein the skirts ( 6 ,  7 ) comprise undulating intermediate parts or portions ( 6   b,    7   b ) to enable injected mortar to also pass into the interior of the holes ( 2 ,  3 ) in the blocks when the spacer/centering element has been mounted.  
   
   
       6 . A spacer/centering element as claimed in  claim 1 , characterised by bounding a central aperture.  
   
   
       7 . A spacer/centering element as claimed in  claim 1 , characterised by being moulded of fireproof plastic material.
