Abstract

The drainage channel (10) is open and has a frame (14) with perforations (32) for fastening bolts for a cover. Pockets (34) near the perforations are open towards the channel centre (20). Alternatively, a fastener part may be connected to the frame or the channel to hold a fastening bolt. Fastener elements to act with fastening bolts, are located in the pockets, on the frame, of the fastener. The fastener elements are removably located via e.g. inserts, and are shaped to act with different fastening bolts. The inserts are held in guides, and can be removed towards the channel centre.

Description

The present invention relates to a gutter, in particular drainage or infiltration gutter and a gutter frame and a fastening part of a gutter for a cover. In particular, the invention relates to a fastening means for connecting a gutter to a gutter cover. The fastener can also be used to connect other parts.

Troughs usually have an opening that is open at the top for receiving inflowing water. A frame for receiving a cover is arranged in the edge region of the opening. This frame usually consists of a metal angle profile, which is held with anchors in the gutter block made of concrete. The frame is fixed in the concrete that has not yet set during the manufacture of the channel. The horizontal strut of the angle profile has perforations, on the underside of which fastening means are provided for the engagement of fastening means for the cover. Such fasteners are e.g. welded nuts. The disadvantage here is that the fasteners must be protected downwards with cover caps so that the fasteners are not blocked by high-swelling concrete. In addition, the fasteners on the construction site are often clogged with building dirt. The handling of the cover caps is relatively cumbersome for large-scale production, since caps are sometimes lost and a lot of effort then has to be taken to make a fastener clogged with concrete feasible.

It is therefore an object of the invention to provide a gutter and a fastener with regard to avoidance of the above problems are easier to deal with. This goal is achieved by a channel according to claim 1 and a fastening means according to claim 8. Advantageous developments of the invention are the subject of the corresponding subclaims.

According to the invention, the fastening means are designed as multifunctional fastening means for interacting with different types of fastening bolts, namely screw bolts and bayonet bolts. This makes it possible, on the one hand, to replace a defective fastening means and / or to change to a different fastening function in the case of a damaged multifunctional fastening means, so that further work, such as e.g. a change of the gutter, can be omitted. It is also possible to switch to a different fastening system at any time.

Furthermore, the fastener according to the invention enables a fast and secure connection of two parts, the type of fastening bolts that can be used being open or being exchangeable.

In one embodiment of the invention, the frame has pockets in the area, preferably below the perforations, towards the center of the channel, in which the inserts are arranged. This has the advantage that when the gutter is made with the frame, due to the pockets closed at the bottom, no concrete penetrates from below into the fastening means and, on the other hand, dirt that penetrates from above is easily removed through the opening of the pockets towards the center of the gutter can. The pockets are preferably only opened towards the center of the channel. This ensures that the bag is closed in its entire contact area with the concrete. It is therefore impossible for concrete to penetrate the bag. The bag does not have to be made of a material connected to the frame, but can be formed solely by a molded part, for example made of polystyrene, in the manufacture of the molded channel body, which molded part is removed again after the molded channel body has hardened, so that the side walls and the bottom of the Bags in the finished gutter are formed by the material of the gutter molding itself.

An insert is arranged in the pocket, which is suitable for different fastening bolts. Alternatively or additionally, the insert can be detachably held in the pocket, for example on a guide, so that it can be replaced when it is dirty. The detachable guide for use can be formed on the frame, the pocket or the channel body. In any case, the insert is spaced from the bottom of the pocket, so that dirt falling from above falls through the insert and can be removed from the pocket towards the center of the channel. The use of an insert which can be used simultaneously for different fastening means, for example a bayonet bolt or a screw bolt, offers two advantages. On the one hand, different fastening systems can be used. On the other hand, if one of the fasteners (eg internal thread) is contaminated, one or more of the remaining fasteners (eg bayonet guide and latch) of the insert can be used. The inserts are either permanently connected to the pocket or frame or through a guide device fixed in its vertical position, for example by grooves or ribs on the pocket walls. These horizontal ribs prevent the fastening means from escaping downwards and are preferably machined without cutting into the side walls of the pockets by means of a squeezing and pressing process, ie in a relatively inexpensive operation. The purpose of fixing the inserts in a defined vertical position is to keep the fastening means at a distance from the bottom of the pocket so that there is sufficient space under the fastening means to clear out dirt falling into the pocket towards the center of the channel. Both alternative or additive systems offered in claim 1 have the advantage that the operational safety of the channel is not only increased to the extent that contamination of the insert is made more difficult, but that the channel can also be used in the event of contamination by using the insert is replaced or on a different fastening bolt, ie another fastening means of the insert is avoided. In addition, different fastening bolts can be used with the gutter, so that different gutters do not have to be manufactured for different fastening systems. The invention thus also saves manufacturing and storage costs.

A nut itself can also be used as an insert. If the cross-section of the pocket is chosen according to the key dimension of the nut to be used, it is additionally ensured that the nut in the pocket cannot turn. The bag thus also represents the rotation lock of the mother. The bag is preferably somewhat lower than that Strength of the mother, so that dirt falling into the pocket through the mother can be removed below the mother towards the center of the gutter. The ribs formed on the pocket walls are preferably formed on two opposite side walls of the pocket.

The pockets preferably have a rectangular, polygonal or circular cross section and are in any case closed at the bottom, so that the penetration of concrete into the pocket is prevented when the gutter is being made. The pocket is preferably welded to the frame, but can also be riveted or otherwise connected to the frame.

Instead of an insert, a multifunctional fastener for different fastening bolts can also be incorporated into the frame in the area of the perforations. Such a solution is very inexpensive to manufacture and still provides a higher level of operational safety than conventional gutter / cover connection systems.

Identical or functionally identical parts are provided with identical reference symbols in the figures.

Fig. 1 shows a gutter element 10 comprising a concrete block 12 in the form of a U-profile and a frame 14 attached during the manufacture of the concrete block 12 in the form of an L-shaped angle profile with a horizontal leg 16 which rests on the concrete block 12 and one in Edge region of the leg 18 pointing vertically upward. The one in the U-profile 12 formed interior 20 forms the inlet area of the channel. A cover 26 shown in FIG. 2 is held in the frames 14 resting on both vertical legs 22, 24 of the concrete block 12. The cover 26 has diagonally extending elongated drain holes 28 for introducing the water into the inlet area 20 of the channel 10. The cover 26 is fastened to the frame 14 by bolts 30. These bolts 30 penetrate perforations 32 in the horizontal legs 16 of the frames 14. Below the perforations, cuboid pockets 34 are formed, within which are arranged fastening means complementary to the bolts, with which the bolts engage. The pockets 34 have such a large vertical depth that there is still enough space under the fastening means held in the pockets 34 to discharge dirt falling into the pockets through the perforations 32 to the interior 20 of the channel 10. For this reason, the pockets 34 are open to the interior of the channel. The pockets 34 do not necessarily have to be cuboid. You can also have a cylindrical or other type of base.

2, the bolts are held in depressions 36 in the surface of the cover 26, so that the bolts 30 do not protrude beyond the surface of the cover 26.

3a shows a detail of such a bolt fastening using the example of a bayonet lock bolt 30. Parts that are identical or functionally identical to the previous figures are provided with identical reference numerals. 3 clearly shows the bolt 30 seated in the recess 36 of the cover 26 with a bolt head 38 which contains an external hexagon and a slot. Arranged below the bolt head 38 is a plate spring 40 which elastically biases the bolt 30 upward against the cover 26. The bolt shaft 42 protrudes through the perforation 32 in the vertical leg 16 of the frame profile 14. At the lower end of the bolt shaft 42, radially extending pins 44 are arranged offset by 180 °. In the pocket 34, a guide 46 with a downwardly extending guide link 48 is formed under the horizontal leg 16 of the frame profile 14, on which the pins 44 of the bayonet bolt 30 slide. The guide 46 has the shape of an upside-down U and is supported on inwardly projecting ribs 56 on the inner walls of the pocket 34. The guide 46 with the guide link 48 can be pulled inwards out of the pocket and can be exchanged for an identical locking mechanism or another locking mechanism, for example a nut. When the bolt 30 is rotated from the illustrated non-locking position by approximately 90 ° to 120 °, the bolt is pulled down into a locking position on the guide link 48. The cover 26 is thus resiliently biased downwards against the horizontal leg 16 of the frame 14 by the plate springs 40.

FIGS. 3b and 3c show a view according to FIG. 3a with other inserts for other fastening means.

In FIG. 3b, instead of the guide 46 from FIG. 3a with the guide link 48, a spring guide element 47 is inserted into the pocket 34 and supported on the ribs 56, which element 47 engages with a correspondingly shaped bolt 49, which has a groove who with a complementary nose engages on the spring element 47. This attachment can be called a jack connector.

In Fig. 3c, a nut 54 is inserted into the pocket, which rests on the ribs 56 in a rotationally fixed manner. It can thus be seen that, based on the invention, different fastening systems can be inserted into the pockets, making it possible to replace defective fastenings or to change from one fastening system to another fastening system without any problems.

FIG. 3d shows a further embodiment of the invention, in which, in contrast to FIGS. 3a to c, the fastening of the fastening means is not achieved by a rib arranged in the pocket, but rather by a narrowing 60 of the lower part of the pocket 35 In the present case, a screw 54 rests on the constriction 60 and is thereby secured downwards. It is important for all inserts that there is enough space under the fastener of the insert and the pocket bottom to be able to remove dirt falling into the pocket.

Fig. 4 shows the frame 14 for insertion into the concrete block 12 of the channel element 10. Parts identical or functionally identical to the previous figures are provided with identical reference numerals. The frame 14 is made of metal, cast iron or plastic and is connected to the concrete block as long as the concrete has not yet set. For the molded block, however, polymer concrete or plastic can also be used instead of concrete. The frame can also be glued to the molded block afterwards, screwed or otherwise connected. The method of connecting the frame to the concrete block that has not yet set would correspond to a positive connection of the frame to the polymer concrete or plastic block that has not yet hardened. For anchoring in the concrete, the frame 14 has anchors 50 pointing vertically downward from the horizontal leg 16, which are preferably perforated and deformed. After the concrete has hardened, the anchors 50 of the frame 14 give an absolutely secure hold on the molded block. The shape of the armature 50 can be seen very clearly in the cross section AA according to FIG. 6. At the lower end of the anchor 50, a spread piece 52 is formed, which serves to additionally improve the integration of the anchor 50 in the concrete of the shaped block 12.

The detail Z in FIG. 7 illustrates once again a detail of a pocket 34 with an integrated bayonet guide 46 for engagement of a quick-release bolt 30, which is already shown in FIG. 3.

FIG. 8 shows a detail Z from FIG. 4 of an embodiment of the invention, in which a hexagon nut 54 is held in the pocket 34 according to FIG. 3b. For this purpose, ribs 56 are pressed into the side walls of the pocket 34, which firmly hold the nut 54 in the pocket 34 at its vertical position below the perforation 32. The width of the pocket 34 is chosen such that it corresponds to the key dimension of the nut 54. The nut is thus not only held in the vertical direction by the ribs 56, but also secured against twisting by the side walls of the pocket 34. Below the nut 54 according to FIG. 8 and underneath the bayonet guide 46 according to FIG. 7 there is still sufficient height in the pocket to remove any dirt that may enter through the perforation 32 towards the center of the channel.

9 shows a pocket 34 with guide ribs 56 for holding an insert 62, which has both a slot 64 for the passage of a bayonet lock bolt and a thread 66 for a screw bolt. The two types of bolts can therefore be used as required without changing the channel. In the event of damage, contamination or use of other fastening bolts, the insert 62 can be exchanged for a new or different one (with different fastening means). 9 and 10 show a vertical cross section at the top and a top view X of the cross section at the bottom.

FIG. 10 shows an embodiment largely identical to FIG. 9. However, there are no guide ribs on the pocket for guiding the insert 62, but the pocket is somewhat widened in its approach to the frame, so that a guide groove 68 is formed between the pocket 34 and the frame 16 for a complementarily shaped region 70 of the insert becomes.

11, 12 and 13 show different possibilities for fastening an insert 72, 74 with thread and bayonet guide for fastening different bolts on a frame 16.

11, the insert 72 is pressed into the perforation 32. The insert 72 is conical in the upper area widened and supported on the correspondingly complementary edge of the perforation. Two ribs of the insert which protrude somewhat outward engage behind the frame 16 and a rib 56 of the pocket. The insert is thus fixed in the vertical direction. 11 shows a vertical cross-section in the longitudinal direction of the gutter at the top left. The figure on the top right shows the cut across the gutter and the figure below shows a top view X.

12 and 13, the insert 74 is designed as a cylindrical body with an internal thread and a bayonet guide. 12, the insert 74 is riveted to the frame 16 and the pocket 34 as a sandwich. In Fig. 13, the insert 74 is welded to the frame.

The pockets can be welded, riveted, clipped or glued to the frame.

In addition to metals and concrete, other artificial stones or plastics can also be used as the frame and shaped stone material. The bag can also have the basic shape of a polygon.

The insert can also have a shape other than the U shape described above. In the simplest case, the insert can be designed as a flat plate, the shape of which corresponds to the basic shape of the pocket and the dimensions of which correspond to the inside dimensions of the pocket. Different fastening means such as nuts, bayonet guides, spring elements or the like can then be fastened to this plate. The plate can in turn be supported on ribs on the walls of the bag or on appropriately profiled side walls of the bag. An elastic element made of metal or plastic can also be used as a support element, which is clamped under the insert and, due to its elasticity, pushes the fastening means away from the bottom of the pocket. The advantage of such a solution is that the bag itself does not have to be provided with a support device such as a rib in any way. The elastic element can, for example, have the shape of a U with elastic vertical legs.

If ribs are used as support elements, these need not extend over the entire width of the wall. They can also be designed as point-like projections which are formed on the side wall at a distance from one another on a horizontal line.

14 shows the cross section of a channel 80 with a channel body 12 made of concrete and a metal frame attached thereon consisting of two L-shaped angle profiles 82 which, in contrast to the angle profiles 14 of the previous exemplary embodiments, are not perforated in their horizontal section. Under the horizontal sections 84 of the L-profiles 82, cavities 86 are formed in the concrete block 12, which serve to engage an elongated fastening part 88 in the form of a fastening strut. The fastening strut 88 is explained further below, inter alia, with reference to FIG. 15.

The elongated fastening strut 88 is inserted transversely to the longitudinal direction of the channel in the recesses 86 below the horizontal struts 84 of the frame such that the longitudinal ends of the Fixing strut 88 come to lie in these cavities and bear upwards against the underside of the horizontal legs 84 of the frame. In the middle of the fastening strut 88, a fastening means 90 is formed, which has both a thread 92 for interacting with a screw bolt and a guide link 94 for interacting with a 1/4 turn lock. This combined fastening means can be worked into the fastening part 88 designed as a metal sheet, for example by punching and cutting. The fastening means 90 serves to interact with a fastening bolt which is arranged centrally in the cover 96 and is supported on a horizontal surface 98 of the cover 96. This fastening option shown in FIGS. 14 and 15 by means of a fastening part 88 thus represents an alternative embodiment to the fastening options according to the previous exemplary embodiments, where the fastening bolts were anchored in the area of the frame.

Of course, an insert which has one or more fastening means can also be detachably held in the fastening part 88.

The fastening part and the insert can be produced as a stamped part, cast part, extruded part, forged part or molded part.

Of course, the fastening means for interacting with the screw and bayonet bolts can not only be used for fastening cover gratings to channels, but also for any other applications in which Parts must be fastened to one another and connected to one another quickly and securely.
