Fig. 4G: Configuración “Lateral”
Equipadas con arandelas esféricas y restringiendo el desplazamiento axial estas unidades de
control solo permiten movimientos laterales en
la junta de expansión. Las arandelas esféricas distribuyen la carga y suavizan el desplazamiento.
Fig. 4H y 4I: Configuración “Universal”
Equipadas con arandelas planas y cojintes elastoméricos la posición de las tuercas permiten
cierto movimiento axial de compresión y de extensión. La posición de las tuercas se ajusta
de tal modo que los espacios no superen los movimientos máximos permitidos para la
junta en cuestión. Los asientos elastoméricos amortiguan la transmisión de vibraciones.
En la figura 4I se sustituyen las tuercas internas por un manguito de compresión.
Fig. 4G: “Lateral” configuration
These control units are equipped with spherical
washers. Axial displacement is restricted and only
lateral movement is allowed in the expansion joint.
The spherical washers distribute the load homogenously and smoothen displacement.
Fig. 4H y 4I: “Universal” configuration
Equipped with plain washers and elastomeric bushings, the position of the nuts allows for
some axial compression and extension movement. The position of the nuts is adjusted to prevent the gaps from exceeding the maximum allowable movement of the expansion joint. The
elastomeric bushings dampen noise transmission.
In Figure 4I the internal nuts are replaced by a compression sleeve.
