Abstract

Una disposizione per sigillare una connessura definita tra bordi distanziati di una coppia di segmenti adiacenti contiene una coppia di flange inclinate in modo opposto sui bordi dei segmenti aventi rispettive superfici piane inclinate in modo opposto definite sui medesimi, una barra cilindrica allungata di tenuta disposta tra e appoggiata sulle superfici piane inclinate distanziate delle flange dei bordi in modo da coprire e chiudere la connessura tra le flange dei bordi, una graffa elastica pieghevole avente una configurazione di sezione di tipo a canale. La graffa elastica è ancorata sotto le flange di bordo e si sovrappone alla barra di tenuta di modo da spingere la barra di tenuta in contatto di tenuta con le superfici piane delle flange dei bordi e in relazione di tenuta con la connessura. Delle porzioni opposte di bordi della graffa elastica hanno configurazioni a gancio, una essendo l'inversa dell'altra per estendersi attorno e sotto le flange dei bordi, mentre una porzione intermedia della graffa elastica è impegnata con la barra di tenuta e configurata nella sua sagoma per conformarsi alla sagoma di un lato della barra di tenuta impegnato dalla porzione intermedia di graffa.
