Abstract

Estructura de pared para la delimitación de una trayectoria de gas caliente (4) en una turbina de gas o en unacámara de combustión, en particular de una turbina de gas, - con al menos dos segmentos de pared (2, 3), que están dispuestos adyacentes entre sí en una zona deunión (5), - en la que en la zona de unión (5) un lado frontal (6) de uno de los segmentos de la pared (2) está dispuestofrente a un lado frontal (7) del otro segmento de la pared (3), - en la que los lados frontales (6, 7) están distanciados uno del otro y configuran entre sí un intersticio (8),que conduce desde un lado interior (9), dirigido hacia la trayectoria de gas caliente (4), de los segmentos dela pared (2, 3) hacia un lado exterior (10), alejado de la trayectoria de gas caliente (4), de los segmentos dela pared (2, 3), - en la que los lados frontales (6, 7) presentan, respectivamente, una ranura de recepción (11) abierta haciael intersticio (8), - en la que un elemento de obturación (15) que puentea el intersticio (8) está insertado en las ranuras derecepción (11) colocadas opuestas entre sí, - en la que una relación de una distancia (A) medida en un fondo de ranura (12) de la ranura de recepción(11) respectiva entre dos paredes de la ranura (14) opuestas entre sí de la ranura de recepción (11)respectiva con respecto a un espesor (S) del elemento de obturación (15) es mayor o igual a 1,1,caracterizada por que un segmento de pared (3) en el lado interior (9) presenta una proyección (18) que se distanciadesde el lado frontal (7), que penetra en una escotadura (19), que está recortada en el lado frontal (6) del otrosegmento de pared (2) en su lado interior (9), en la que la proyección (18) presenta una sección transversal cónica,que se estrecha hacia el intersticio (8).
