<p>One or both the ends of equal lengths ( 92 ), obtained by a square shaped piece ( 3 ), can be fixed, in a manner and by means which are well known in the art, to lengths ( 91 ) of " C " shaped pieces ( 1 ) having equal sides. By using only one length ( 91 ) it is possible to obtain a comblike structure ( 130 ), while by the use of two lengths ( 91 ) it is possible to made an upright ( 90 ) which is formed by a " ladder " type structure. Two lengths ( 101 ) of a shaped piece ( 4 ), which is similar to the shaped piece ( 3 ) except that a corner portion provided with a groove ( 43 ), are connected, in a manner and by means which are well known in the art, to respective lengths ( 102 ) of rectangular shaped pieces ( 5 ) thus forming rectangular frames ( 100 ) which in their turn can be fixed, by means of screws extending through the lengths ( 102 ), to respective lengths ( 92 ) in order to form wall-attached or floor-supported framework structures.</p> |
