Definitions

  • the invention relates to a device for producing drainage channels provided with slot-like openings for the surface drainage of traffic areas, at least consisting of a sliding formwork and a tubular form of formwork for the inner channel of the drainage channel, with a tubular body aligned parallel to these walls between the walls forming the outer formwork sliding recording of a hose body brought to its outer dimensions under internal pressure is arranged.
  • troughs for line drainage are arranged in the plane.
  • drain gutters are usually used, which have slots on their top that are so narrow that they do not have to be closed.
  • troughs provided with slot-like openings are mostly made of precast concrete. The transport of the finished parts can be described as cumbersome and cost-intensive.
  • Drainage channels provided with slot-like openings can also be made in in-situ concrete.
  • the use of a special formwork and an inflatable rubber formwork has proven to be disadvantageous.
  • a slot cutter then has to be used to make slot-like through openings.
  • the cumbersome production is disadvantageous, but it must also be considered an additional cost if the PVC pipe used practically lost formwork represent gene.
  • Plastic parts remaining in the gutters also pose a fire hazard.
  • a tubular body is provided next to a feed shaft for concrete and also only guided over the width of this shaft, which surrounds a tubular body.
  • the tubular body is made relatively thick-walled, so that the concrete already shaken in this area has a correspondingly massive effect on the then remaining tubular body after leaving the tubular body.
  • a metal profile fastened to an upper end formwork is intended to enable the slot-like passage opening to be manufactured continuously, but this metal profile is designed to be substantially longer than the tubular body. In the continuous production of the drainage channels, this metal profile must therefore constantly rest on the hose body and slide along it. This cannot have a good effect on the fresh, not yet hardened concrete, and especially the limitation of the walls in the slot-like through openings cannot experience any particular surface compaction.
  • SA-A-3959977 Also known is a device for producing drainage channels provided with slot-like openings for surface drainage of traffic areas (SA-A-3959977), which consists of a sliding formwork and a tubular formwork form for the inner channel of the drainage channel.
  • SA-A-3959977 There is an external formwork with appropriate walls.
  • a formwork part is connected in one piece to this outer formwork, which could be referred to as a tubular body in order to slidably accommodate a hose body brought to its outer dimensions under internal pressure.
  • this tubular body is not designed as a circumferentially closed tube because a strip-shaped area of the “tubular body” remains open via connecting webs to the outer formwork. These two connecting webs then formwork elements in order to keep the area free for the slot-like passage opening.
  • the object of the invention is therefore to create a device of the type mentioned at the outset, with which a drainage channel provided with a slot-like through-opening can be produced in an optimal and also precise manner using a formwork hose in in-situ concrete.
  • the tubular body is designed as a thin-walled tube for receiving the hose body in a sliding manner and that at least over a part of the length of the tubular body a radially protruding formwork shield is arranged on the upper side thereof to form the slit-like through openings, and in that a feed shaft for concrete is provided in the area of the longitudinal expansion of the tubular body.
  • the tubular body Due to the design of the tubular body as a thin-walled tube, the tubular body is practically still in the appropriate shape when leaving the sliding formwork. external dimensions available and then supports the inner wall of the freshly concrete concrete body. Precise production using the in-situ concrete method is only possible if the tubular body and the hose body and also the peeling plate are used in a matched manner.
  • the concrete After leaving the device, the concrete has sufficient hold solely due to the precisely defined hose body, whereby there is also no trace of the danger of buoyancy in the freshly produced concrete part for the hose.
  • tubular body at its rear end in the sliding formwork direction is bevelled at an acute angle from top to bottom, then the guarantee is given that, on the one hand, the slotted concrete section above the hose body is additionally supported longer and, on the other hand, the finished concrete body is continuously released , If the end of the tube body extends at right angles to the longitudinal extent of the tube body, there is rather the possibility of forming a transverse crack.
  • a further advantageous embodiment is that the peeling plate arranged on the upper side of the tubular body is arranged starting from the end of the tubular body lying at the rear in the sliding formwork direction and is guided at least approximately over half the length of the tubular body. It is therefore ensured over a relatively long formwork area that the boundary walls of the slot-like through opening are supported and wiped off.
  • the peeling plate can optimally penetrate into the already existing concrete to form the slot-like through opening, it is provided that the peeling plate drops at an acute angle to the end lying at the front in the sliding formwork direction.
  • the peeling plate is tapered in a cutting-like manner at the end lying at the front in the sliding formwork direction and falling at an acute angle. This prevents the concrete from being pushed away in any way, but the penetration process is optimal and Concrete is additionally compacted in the area of the boundaries of the slot-like through opening.
  • the formwork shield can also be adapted to slot-like through openings of different sizes or to different cross-sectional shapes thereof, it is proposed that the width and / or the cross-sectional shape of the formwork shield arranged on the tubular body be adjustable.
  • a variant provides that two or more formwork shields can be fixed one above the other in a box-like manner in order to adjust the width of the formwork shield.
  • the adaptation options to the various requirements are practically unlimited. There is therefore not only the possibility of a cylindrical tube body and thus an inner cross section of the trough which is circular in cross section. According to a variant, it is therefore proposed that the tubular body have an internal and external cross section that is adapted to the cross-sectional shape of the formwork hose.
  • the optimal effect of the device is further improved if the ends of the compactor vibrators used in the concrete feed chute are used. Optimal compaction of the concrete can therefore also be ensured, taking into account the suitable concrete consistency.
  • Another advantageous construction provides that the peeling plate on the tubular body is only arranged next to the feed shaft for concrete. After the first intensive compaction process, the formwork shield is thus inserted, so that the concrete is additionally compacted in the area of the slot-like through opening.
  • the device according to the invention has created a possibility of sensible use of a hose body. It is therefore provided that the hose body is laid out over a relatively long distance and remains in its outer dimension by compressed air, the sliding formwork being movable along the laid-out formwork hose. It can cover long distances, for example several hundred meters can be manufactured on site in one work step, whereby all the necessary curves in the course of the trough can be easily mastered.
  • Fig. 1 is a schematically illustrated side view of the device according to the invention.
  • FIG. 2 shows a section along the line II-II in Fig.1.
  • Fig. 3 is the view III in Fig. 1;
  • the device according to the invention for producing drainage channels 2 provided with slot-like through openings 1 for the surface drainage of traffic areas essentially involves a sliding formwork 3 and a tubular formwork form for the inner channel 4 of the drainage channel 2. Between the walls 6, 7, 8 forming the outer formwork 5 a tubular body 9 aligned parallel to these walls 6, 7, 8 is arranged for slidably accommodating a tubular body 10 which is brought to its outer dimensions under internal pressure. Furthermore, at least over a portion of the length of the tubular body 9, a radially projecting peeling plate 11 is arranged on the upper side thereof to form the slot-like through openings 1. It is therefore possible to produce the trough 2 with the slot-like through openings 1 in a sliding formwork construction in one operation.
  • the hose body 10 is designed for a corresponding length, which can also be several hundred meters. At one end, the hose body 10 is sealed airtight (jammed or tied). The tubular body 10 is passed through the tubular body 9 in the device, whereupon a compressed air unit is connected to bring the tubular body 10 into the inflated shape. In this form, the hose body 10 is slidably received in the tubular body in the manner of a fitting session, so that the manufacturing process can begin on site.
  • the tubular body 9 is designed as a thin-walled metal tube. A stainless steel version can be provided, but care must always be taken to ensure that the inner surface in particular is precisely machined. The thickness of the tube can be adapted to the individual applications, but a relatively thin wall is always provided. In the context of the invention, however, a plastic tube or a tube made of other materials can also be used, although a thin-walled design is always required.
  • the tubular body 9 is chamfered at its rear end 12 lying in the sliding formwork direction at an acute angle from top to bottom. This is an optimal design for the good effect of the sliding formwork, since the hose body 10 and also the concrete body formed is released continuously in axially slow steps.
  • the peeling plate 11 arranged on the upper side of the tubular body 9 is arranged starting from the end 12 of the tubular body 9 lying at the rear in the sliding formwork direction 13 and is guided at least approximately over half the length of the tubular body 9.
  • the side surfaces 14, 15 of the formwork shield 11 converge radially outwards. Furthermore, the peeling plate 11 drops at an acute angle to the end lying at the front in the sliding formwork direction 13. In addition, the peeling plate 11 is tapered in a cutting-like manner at the end 16 lying at the front in the sliding formwork direction 13 and falling at an acute angle.
  • the peeling plate 11 arranged on the tubular body 9 is adjustable in its width and / or in its cross-sectional shape.
  • a wide variety of technical solutions can be used.
  • the peeling plate 11 is welded as a whole to the tubular body 9.
  • screw solutions are also conceivable, with, for example, the formwork shield 11 being attached to tabs welded to the tubular body 9.
  • the peeling plate 11 can also be held interchangeably on the tubular body.
  • One variant provides that two or more formwork shields 11 can be fixed one above the other in a box-like manner to adjust the width of the formwork shield 11.
  • tubular body 9 with an inner and outer cross section adapted to the cross-sectional shape of the tubular body 10.
  • the device provides a feed chute 17 for concrete in the area of the longitudinal expansion of the tubular body 9, with the ends of the compactor vibrator 18 inserted near the tubular body 9.
  • the peeling plate 11 on the tubular body 9 is only arranged next to the feed shaft 17 for concrete.
  • the hose body 10 used when working with the device is laid out over a relatively long distance and brought to its final outer dimension by compressed air, the sliding formwork 3 being movable along the laid out hose body 10. After curing, the pressure in the hose body 10 is released and the hose body 10 is pulled out over the entire length of the finished and hardened trough.
