Street gully with inlet frame .with adjustable

height

The present innovation relates to a street gully formed from a tubular body upper manhole, in which a metal frame is attached, which consists of two coaxial and such screwed together parts that the height of the frame can be changed, so that its upper surface can be brought exactly onto the road surface, which can change when the road surface is renewed. The said frame is with a recording for provided a detachable closure cap that is inserted in this way can be that its upper surface is always flush with the upper surface of the frame.

The previously known street gullies comprise a tubular body with an upper access opening, in which a frame is mounted which carries a removable closure cover. The frame consists of one single piece and thus has an unchangeable height.

Therefore, when the road surface is renewed, which increases the height of the carriageway level, it sinks this frame with the cover in the outer surface of the road surface and creates a depression that Bumps and vibrations in the vehicles driving over them, especially in the heavier and / or faster, causes. This will put the vehicles in

dangerously overuse and damage the tires. It also leads to damage the roadway.

In order to remedy this evil, a must when using the previously known gullies around the frame about 30 cm wide strips of the road surface are torn open. Then the frame has to be dismantled and changed around the edge of the inlet opening of the gully an embankment of grit or cement bricks and cement or lime mortar to raise the frame. However, this measure is tedious Labor and high costs associated, so that it is rarely carried out in practice.

According to the present innovation, this evil is to be remedied with the help of a gully, which with a the access opening delimiting and is provided with a removable cover closed metal frame. This frame consists of two coaxial tubular parts that slide into and together are screwed, one of these tubular parts being rigidly connected to the tubular body the other, which carries the lid, is rotatable about the former. This results in a frame with nachi-s> adjustable height so that the upper side of the movable part of the frame and the cover carried by this can be set up exactly coplanar to the road surface when the pavement repair is finished is.

There are devices for rotating the movable part of the frame around the rigid part with the help of Suitable tools are provided so that the frame height can be adjusted as often as necessary.

These and other special features of the innovation are described in the following description, which refers to relates to two forms of implementation of the innovation and in the reference to the attached drawings

is taken, explained in more detail.

Figure 1 shows a first embodiment of the street gully. In the left half the gully can be seen in axial section; in the right half of the drawing is a front view of the rigid inner part of the frame can be seen, while the movable outer part of the frame is shown in axial section.

FIG. 2 is a schematic axial section view of the gully of FIG. 1 with a different arrangement the frame parts.

FIG. 3 shows a second realization form of the gully, the one in the left half of the drawing is shown in the axial section, while in the right half of the drawing the inner movable part of the frame with part of its outer tubular brim in front view can be seen ". The rigid outer part of the frame and the tubular body are shown in axial section.

FIG. 4 is a schematic axial section illustration corresponding to the realization form of the gully Fig. 3, in which the two components of the frame and the lid in a different arrangement are shown.

Figure 5 shows the GuIl y shown in Fig. 1 and 2 from above, without a cover, around the To make the position of the holes for receiving a tool visible, with which the movable Part of the frame can be rotated around the rigid part.

FIG. 6 shows a universal tool suitable for this purpose from above.

FIG. 7 is a sectional view taken along line A-A of FIG. 6.

FIG. 8 is a perspective view of a detail of the upper part of the frame in FIG one of the bores provided in the moving part of the frame for receiving the tool / for the embodiment of FIGS. 1 and 2 can be seen.

The gully consists of a tubular body 1 irdt circular or polygonal, in particular rectangular or square cross-section and can be 'prefabricated in a conventional manner or manufactured on site and provided with an upper manhole.

Above the manhole body is at its upper access opening a frame generally made of metal for receiving a removable closure cap assembled.

According to the innovation, the frame consists of two coaxial tubular parts that are nested and screwed together to ensure that they move against each other and thus up to certain maximum values can approach or move away from one another, so that a multi-part frame with adjustable height results. In the embodiment shown in Fig. 1 and 2, the gully consists of one tubular body 1 open at the top and is the rigid one Part of the frame is the inner part 4, while the movable part 5 is the outer part, which is why part 4 is also is provided with a robust external thread 6, while the movable part 5 has an internal mating thread 7

has, in which the thread 6 engages. The inner part 4 of the frame has at the lower end a wide flange 8 which protrudes outwards and over which the part 4, 8 of the frame is attached to the upper opening of the tubular body 1 and to the bedding 10 which the original road surface 11 is applied (Fig. 1), in which above the body 1 a cylindrical Trough 9 is formed, which runs coaxially to the tubular body 1 and whose diameter is slightly larger is than the outer diameter of the Rahir part 5.

The movable part 5 has in its inner cavity in the lower part the mating thread 7, which engages in the thread 6 of the part 4, while in the upper part the frame part 5 protrudes towards the diameter axis _{r so} (j _a ß (j _he inner diameter in is essentially equal to the inner diameter of the frame part 4 and thus a shoulder 18 is created, which serves as a stop when it comes into contact with the upper edge of the frame part -4, as soon as the parts 4 and 5 are screwed together as far as the stop, that is, when the The frame has the minimum height (Fig. 1) _f while the lower side of the tubular part 5 remains slightly away from the upper surface of the flange 8 o In the last short section of the upper part, the inner surface of the part 5 expands outwards and forms an annular step 3 , which serves to accommodate the protruding peripheral edge 2a of the lid 2, which must be aligned with its flat outer surface with the upper edge plane of the part 5, so that the height of the said end section must be essentially equal to the height of the edge 2a »

In the paragraph or in level 3 there are blind holes or vertical niches at equal angular intervals provided with semicircular cross-sections 19 (e.g. four in the embodiment of FIGS. 1, 2 and 4), which serve to accommodate a tool, with part 5 can be turned against part 4 without difficulty,

if the multi-part frame is to be raised from the minimum height shown in FIG. 1. Fig. shows the arrangement of the frame parts after two renewals of the road surface 11 with the application of the layers 11a and 11b at different times.

The thread strips 6 and 7 develop in height to a length that corresponds to at least twice the value of the maximum change in size provided for the multi-part frame 4, 5, so that there are always at least as many turns in engagement as is necessary to ensure that the stresses to which the movable part 5 of the frame is exposed during traffic can be transmitted via said screw connection 6, 7 to the rigid part 4 without deformation or breakage, which jeopardizes the effectiveness of the frame could graze, and without later next: emergency measures can be made difficult or even impossible. ' Because it is provided that the movable part 5 of the • frame is attached on the outside and the part 4 on the inside, the area in which the threads 6 and 7 are located is protected against the ingress of dust or foreign bodies at the applicator, the layers 11a, . · 11b ... the road surface protected. During this work, it is also advisable to place ^{a temporary protective tube around the frame between the 1} opening 9 and the outer wall of the part 5, which is removed after the work concerned, and then, if necessary, fine adjustment of the upper surface of the Partly to that of the last applied layer 11a, 11b, ... of the road surface.

In the variant shown in Fig. 3, the gully consists of a tubular body la, the Cross-section is much larger than that of the manhole, which is therefore in. A reinforced concrete slab 1b is located. In this implementation variant, the rigid part of the frame is the outer part, while the

M * "· ■■,

movable part 5a is screwed into part 4a.

The part 4a is anchored in the plate 1b and in the bedding with the help of an external intermediate flange 8a, which is sunk into the plate Ib during casting. This flange forms the bottom of the coaxial with the body 1a cylindrical trough 9. The inside diameter of this trough is larger than the outside diameter of Part 4a. In this embodiment, the inner part forms 5a of the Rahirens, which is the movable part, at the top an annular flange 20, the extends outward so that it not only covers the upper edge of the part 4a and over this goes out, but is then also bent down to a cylindrical brim 21 around the outer side wall of part 4a runs around and the outer diameter is only a little smaller than that Inner diameter of the cylindrical trough 9. This rim 21 surrounds and protects the threaded areas 6 and 7 against the ingress of material, increasing the durability of the screw connection between the two Frame parts 4a, 5a could be affected ,, Im Flange 20 are blind bores 19a, which serve to accommodate the tool ·· with that of the movable one Part 5a of the frame is rotated when readjusting against the rigid part 4a, as already described above.

One for use in gullies with frames of any size within a given area Suitable universal tool (see Fig. 6 and 8) consists of two metal struts connected to one another via B'reuz 12, which have polygonal cross-sections, so that they form guides for sliders 16, the one layer can take that of those of the niches or bores 19 and 19a in the relevant parts 5 and 5a dor frame corresponds.

As a result, the tool should not be universally usable will. A robust pin or arm 13 protrudes downward from each slider 16. In the vicinity of the The free end of this pin or arm is a clamp or some other stop device 15

intended. The end portion 14 of each arm is cylindrical in shape and its diameter is dimensioned so that it penetrate into a niche 19 or hole 19a can, while the length of the part 14 is less than the depth of the niches or bores 19, 19a. The sliding parts 16 are provided with devices 17 for locking on the respective struts 12 (e.g. Screws).

Regarding the first embodiment, it should be noted that if a gully is to be installed, in the bedding 10 and a tubular body 1 is inserted into the ground if this is prefabricated is. Or, this tubular body is manufactured on the spot by the conventional method. A cylindrical recess for receiving the frame 4, 5 is produced in the bedding. The inner one Part 4 is attached via the flange 8 to the tubular body 1 and to the bedding 10 so that, if the part 5 is applied thereon, the upper surface of the latter and that of the lid 2 substantially come to rest on the level of the road surface 11.

When applying a new road surface 11a after damage to the previous ceiling 11 or after the bedding 10 has fallen, only the movable one needs Part 5 of the frame to be rotated until it is on the level of the new surface of the new Road surface 11a is located., This is repeated each time, when a new pavement layer 11a, 11b, .... is added. The turning of the part 5 happens with the above-described universal tool after removing the cover 2. For this purpose, the Screws 17 loosened and the sliders 16 are on

the support and guide struts 12 moved so that the .Arme 13, 14 to lie coaxial with the niches 19 come. Then the sliders 16 are then with the help of the devices 17 (in particular screws) fixed on the struts 12. The tool is then guided downward until the ends 14 of the arms 13 are in penetrate the niches 19. Then the ends of two of the struts 12 are held by one person or the ends captured by at least two struts 12 by two people and the tool and with it the movable one Rotated part of the frame until the top surface of part 5 is on the same level as the new pavement 11a.

In the embodiment shown in FIGS. 3 and 4, the moving part 5a is adjusted of the frame to the rigid part 4a in essentially the same way.
