Frame for gratings for surface drainage

The innovation concerns a frame that serves as a holder for gratings can be used for surface drainage both in in-situ concrete and in prefabricated channels. The ones known so far Frames for gratings for surface drainage consist of angle profile rails, one edge of which serves as a support for the grating serves, while the other edge forms the guide element of the grid grate. The frame was fastened in in-situ concrete mostly through welded or punched anchors. These frames are only used when creating surface warmer channels used where the actual gutter by Ein.-halen and on-site concreting is created. One use of these frames for machine-made prefabricated drainage channel bases is impossible because a corresponding locking option on the prefabricated drainage channel part is not given.

A special attachment for machine-made gutter parts is known, but it is specifically only for these prefabricated parts can be used and, moreover, is rather cumbersome and expensive to construct. A use of this essay when creating the channels by local concreting is not possible.

The innovation has therefore set itself the task of constructing a frame from standard metal profiles that are on the market, which can be used once as a normal frame as before when using in-situ concrete when creating the channel and also,

is to be used at the same time for prefabricated Aflou gutter parts. To solve this problem, it is proposed instead of the previously used ver Angle profile rails on the two long sides of the frame, other standard profiles on the market to be used.

According to the embodiments mentioned in the drawing, for example For the two long sides of the frame an isosceles or unequal T-profile or other mass-produced one Special profiles are used. By using this special frame, according to the illustrated embodiments, a number of Benefits achieved.

when creating the channels by local concreting is opposite to Previously known angle profile frames given a much better toothing in the concrete, and thus a secure locking of the frame in the in-situ concrete. Attempts in this direction have shown that an attachment of locking anchors, as in the known angle profile frames, not necessary is.

If the frame, according to the innovation, is for prefabricated drainage channels is used, there is a secure locking on the prefabricated part because the frame locks over the outer edge of the prefabricated part and part of the frame is interlocked with the road surface to be connected (concrete or macadam). Another essential one The advantage lies in the economic efficiency through the use of standard profiles available on the market for the lateral guide elements of the frame.

Various embodiments are shown in the accompanying drawings.

using a T-profile as a guide element for the grating.

Fig. 2: Shows a section through an embodiment of the frame with grate using prefabricated chins.

As can be seen in Figure 1, the frame according to the innovation a T profile is used for the two long sides (1 + la). This T - profile consists of the guide element (i) of the grate, the support part (la) for anchoring and interlocking in the road surface (concrete, macadam or the like) and the grating support surface (2) of the frame. To connect the two long sides of the frame, a flat iron is sufficient as the connecting part (3). Of course, it can also be angled Profile can be used as a connecting part (3). Bsi the The frame shown in Fig. 2 was for the two long sides (1 + la) a standard window steel profile is used. In this embodiment The innovation is a particularly intensive interlocking of the supporting part

with the road surface (concrete, macadam or like) given. In any case, when using this frame on a prefabricated channel (4) is a good locking option given over the outer edges of the prefabricated channel (4).

In Figure 2, the grating (5) can also be seen in the frame. Instead of a grating, other concrete covers are also suitable, Thermoset concrete or plastic.

Other profiles are also suitable for use as a guide element (i) of the grating and support part (la) of the frame. For example the use of a standard cross steel would also be very beneficial.

Claims (4)

Protection claims 1) Frame closed on all sides in the upper part for gratings for surface drainage, which are used both for prefabricated channel parts and for creating the channels by concreting locally can, thereby gekannzeichne "·. that instead of a known angle profile a profile is used for the two long sides of the frame, that protrudes beyond the guide part for the grating (i) of the frame and a support part (la) for the purpose of locking and fastening in the subsequent road surface (concrete, macadam or similar) forms. 2) frame for gratings for surface drainage according to claim 1, characterized in that equal or unequal leg T-profiles (Fig.l) form the two long sides of the frame. 3) frame for gratings for surface drainage according to claim 1, characterized in that the two longitudinal sides (i) of the frame through Window steel profile (Fig.2) are formed. 4) frame for gratings for surface drainage according to claims 1 - 3, characterized in that the longitudinal sides (i) of the frame are connected to form a unit by flat iron (3).
