Abstract

DISPOSITIVO DE OBSERVACION DE TAMAÑO DE CARGA EN UNA PIEZA DE CONSTRUCCION EN QUE ESTA COLOCADO UN CONDUCTOR DE EJE DE LUZ (LWL) A LO LARGO DE LA PIEZA DE CONSTRUCCION EN FORMA DE MEANDRO Y EN AMBOS EXTREMOS SE CONECTA CON UN EMISOR O RECEPTOR DE LUZ. ESTE DISPOSITIVO DEBE ESTAR FORMADO Y EL LWL LLEVARSE A LA POSICION DE DILATACION A MEDIR, DE TAL MODO QUE CON LA DILATACION SE PRODUZCA UNA VARIACION DEL RADIO DE ARQUEAMIENTO Y CON ELLO DE LA AMORTIGUACION DE LUZ. LA SOLUCION CONSISTE EN QUE A) EL LWL (1) SE COLOCA EN UNA PLACA LONGITUDINAL (2) CUYA PARTE INFERIOR SE ADHIERE A LA PIEZA DE CONSTRUCCION, B) LA PARTE SUPERIOR (3) DE LA PLACA TIENE UNA RANURA LONGITUDINAL EN QUE SE COLOCAN DOS CARRILES DESLIZADORES (4, 4'') CON UN ESPACIO INTERMEDIO (5) EN EL CENTRO DE LA PLACA, Y CADA CARRIL SE ATORNILLA (6) FIJAMENTE EN EL EXTREMO EXTERIOR CON LA PLACA, AUNQUE SE MUEVE EN EL EXTREMO INTERIOR MEDIANTE UN AGUJERO LONGITUDINAL (7), Y C) EL LWL (1) SE ADHIERE FIRME Y LONGITUDINALMENTE A LOS CARRILES DE DESLIZAMIENTO (4,4'') PERO SE COLOCA MOVILMENTE EN EL ESPACIO INTERMEDIO EN UN ARCO (SEGMENTO SENSOR S). UN DISPOSITIVO SENSOR LWL TAL SIRVE PREDOMINANTEMENTE PARA MEDICION DE ARQUEAMIENTO Y CON ELLO PARA OBSERVACION DE PIEZAS DE MONTAJE DE PUENTES.
