Covering grillage for draining gutters with stiffener - has stiffening profiles with brackets for holding in draining gulley top

摘要

The gulley grillage cover for gutters is provided with a stiffening angle profile or stiffening rib. The grillage cover has systems for exerting clamping force after it is mounted on the drainage hole. The covering grillage (6) has formed or wave form locking parts (10) on stiffening profile. These locking parts engage on vertical insertion with the gutter channel (2) top of the drainage gutter (1). The locking part (10) is a curved bracket. These locking components are arranged in staggered pattern. This pattern ensures sufficient clamping force even if few locking points are used in smaller gutter covers.
