| 摘要 |
<p>The invention relates to a prefabricated part (1) which is used to form vertical and/or inclined facing (2) and which takes the form of a straight parallelepiped. The base or lower side face (3) of the part is provided with projections (4) which are coupled in opposing recesses (5), having an identical cross-section, provided on the opposing upper side face (6) of the part (1) to which it is to be assembled in order to form the facing (2). The upper side face (6) of the part (1) is provided with a central longitudinal recess (7) defining two straight side strips (8) for supporting the lower face (3) of the part (1) to which it is to be coupled, thereby defining a housing for aggregate. One of the vertical faces (12) of the part (1) is provided with a recess (13) which is coupled to the vertical end (1), having the same recess (1), of the opposing side face (12) of the part (1) to which it is to be coupled, thereby defining a housing for aggregate.</p> |
