Tijolinha Header



The header system was initially intended to be the bond beam but was revised with the realization that there was going to be too much tela (screen) and it would demand additional un-needed mullion infrastructure to support it. The roof loads will continue to be transferred through the bond beam to the columns and the header height and structure for all openings has dropped to the 215 cm. The tijolinha header will have to support only itself and the small sections of wall above. Its' construction (as pictured above consists of a wood formwork (cut from off cuts of column form), two pieces of 3/8 or .8cm rebar that is buried in the first mortar joint (massa), two courses of tijolinhas (the smaller brick), and tijolos oito furros (8 holes) above with 4/2 rebar in the mortar joint. A plumb bob is used to check for plumb and dry line is set in each course level (nivel) and strait (reta). The initial header height is pulled from the FFE (Finish floor elevation) dry line and snapped across all coloumns.
