EL ELEMENTO PARA IMPERMEABILIZAR EL ANGULO EXTERIOR DE UNA PIEZA DE CONSTRUCCION QUE SOBRESALE DE LA SUPERFICIE DEL TEJADO CONSISTE EN UNA SOLAPA FLEXIBLE (10) CON UN EXTREMO ESENCIALMENTE SEMICIRCULAR (14). PARA OBTENER UN ELEMENTO IMPERMEABILIZANTE DE CONSTRUCCION FACIL Y USO UNIVERSAL, SE PROPONE FORMAR LA SOLAPA (10) COMO ELEMENTO PLANO DE POLIISOBUTENO, POLIVINILCLORURO O BETUN Y PROVEER SU EXTREMO (14) CON UN ESCOTE (16) SIMETRICO AL CANTO ALTO DEL ANGULO EXTERIOR CON UN ANGULO CENTRAL (22) DE 20 A 60 (40 COMO DIMENSION IDEAL), CUYOS PUNTA (24) Y ANGULOS (28,30) ESTEN REDONDEADOS. EL RADIO DE LA PUNTA (26) REDONDEADA Y LOS RADIOS (32,34) DE LOS ANGULOS REDONDEADOS ASCIENDEN PREFERENTEMENTE A 15MM. ES RECOMENDABLE QUE EL RADIO (36) DEL EXTREMO (14) NO MIDA MENOS DE 70MM, Y PREFERENTEMENTE MAS DE 100MM. PARA IMPERMEABILIZAR UN ANGULO EXTERIOR, SE MONTAN 2 ELEMENTOS DE IMPERMEABILIZACION SUPERPUESTOS UNO AL OTRO Y CON SUS RESPECTIVOS ESCOTES (16) EN DOS LADOS OPUESTOS. The element consists of a flexible tab (10) having a substantially semicircular end portion (14). To create a sealing element which can be manufactured particularly easily and is at the same time universally usable, it is proposed to design the tab (10) composed of polyisobutene, polyvinyl chloride or bitumen in a plane configuration and to provide it, in its end portion (14), with a sector-shaped recess (16) which is arranged, in the installed condition, symmetrically to the upward-projecting edge of the external corner and whose central angle (22) is 20 DEG to 60 DEG , preferably 40 DEG , whose apex (24) is rounded out and whose corners (28, 30) are rounded off. The apex radius (26) of the rounded-out portion of the apex (24) and the corner radii (32, 34) of the rounded-off portions of the corners (28, 30) lying next to the recess (16) are preferably 15 mm. The radius (36) of the end portion (14) should not be less than 70 mm, preferably greater than 100 mm. To seal an external corner, two sealing elements with oppositely arranged recesses (16) are attached, one lying above the other.
