DE2727790A1 - Covering grillage for draining gutters with stiffener - has stiffening profiles with brackets for holding in draining gulley top - Google Patents

Abstract

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.

Description

Cover grate for drainage channels

The invention relates to a metallic cover grate which is through Clamping force locked on a drainage channel, the invention being a further development of the DBGM 77 02 231 represents.

According to the aforementioned DBGN, a drainage channel with a lockable Cover grate became known. This grip in the vertical direction of the gutter channel Locking parts, the locking on the drainage channel by the clamping force takes place after placing the cover grating. This idea also lies with the new invention underlying.

The further development of the invention lies in the different design the grating and the locking parts.

A curved or corrugated shape of the locking parts is a special intervention area on the drainage channel is no longer absolutely necessary.

For smaller grating lengths, the locking parts are offset Despite fewer locking points, there is sufficient clamping force to lock the grate in place given.

The torsional stability of the grating itself can also be achieved by a continuous bevel can be achieved to a sufficient extent.

The invention is illustrated in the accompanying drawing as follows: Figure 1 shows a section through a cover grating with curved or corrugated Locking parts (10).

Figure 2 shows a section through a cover grating with arched or curved corrugated locking parts (10) and continuous bevel (5) for torsional rigidity the cover grate and the drainage channel part (1).

Figure 3 shows the plan view of a cover grate, which is offset detects arranged locking parts (10).

In Figure 1 you can see the cover grate (6), with adhesive knobs (7), inlet slots (8), grate support surface (9) and continuous stiffening brackets (4). On the continuous Stiffening bracket (4) is a curved or corrugated locking part (10) appropriate. The locking part (10) is expediently only to the outside arched. But it is a combination of external and internal curvature, for example due to a corrugation, quite conceivable.

Furthermore, the locking part (10) can be designed in such a way that that after engagement in the gutter channel (2) of the drainage channel (1) by the tension the locking part (10) is deformed in such a way that an equivalent of the gutter channel (2) the following detection area (11) is in vertical position in the gutter channel.

In Figure 2, the curved or corrugated locking part (10) is as U-shaped bracket formed. This is more rational in production than individual ones Locking parts (10).

After engagement of the curved or corrugated locking part (10) In the gutter channel (2) of the drainage channel (1), the cover grate is pushed up to the Contact surface (9) pressed in and thereby a clamping force of the locking part (10), which ensures that the cover grate is securely locked in place.

The torsional stiffness of the cover grating (6) is shown in FIG a continuous bevel (5) is reached.

In Figure 3, the top view of the cover grate (6) is shown, wherein the offset arrangement of the locking parts (10) can be seen. In general four locking parts are used for 1 m long cover gratings, each with two face to face.

For short cover gratings, for example, 0.50 m in length are sufficient two locking parts (10), both locking parts are to be arranged offset.

The cover grate (6) is due to the curved or corrugated shape of the locking parts (10) Can be used for practically every drainage channel (1), provided that the dimensions of the cover grate be designed accordingly. A clamping effect through the locking parts (10) is achieved to a sufficient extent.

Detaching the cover grate (6) is also problem-free at any time possible.

In addition, it would be possible to place the locking parts (10) in the lower Area to bend so that a connection in corresponding recesses in the Gutter channel (2) would be possible.
