Definitions

  • the invention relates to an explosion-protected reinforced concrete room cell, in particular a room cell transformer station according to the preamble of claim 1.
  • the explosion protection of the reinforced concrete room cell according to the invention is intended in the event of an explosion in the interior of the room cell to protect the immediate surroundings and the people in the room from flying parts.
  • transformer stations which consist of a reinforced concrete room cell according to the invention
  • explosive discharges can occur mainly as a result of a short circuit.
  • Such explosions cannot be ruled out, particularly in the case of room cells that are largely without supervision.
  • transformer stations of the type described which are situated in the forest, for example, from residential areas in order to transform the long-distance lines to the supply lines.
  • Explosion-proof room cells are protected in different ways against internal explosions and are also forced-ventilated.
  • the forced ventilation that is necessary as a result is not capable of reducing the sudden overpressure in the interior of the room cell sufficiently quickly in the event of an explosion, which leads to destruction and thus to the described risk potential.
  • explosion protection requires adequately dimensioned openings to quickly release the explosion overpressure, which connect the interior with the atmosphere.
  • test pressures in the order of magnitude of, for example, 1.5 t / m 2 are assumed.
  • overpressures lead to the immediate, at least partial, destruction of one or more panes of the building with a corresponding risk potential from flying parts.
  • room cells must be protected against the ingress of rainwater. If the openings are sufficiently large to reduce the internal overpressure, sealing them creates considerable difficulties. It is known to create the openings in such a way that a slope arises which the rainwater cannot overcome. Cover plates are used to protect against wind pressure. It has been found that such space cells generally do not meet the requirements in practice. Either the required seals are not achieved or the attempt to explode leads to the feared destruction and the described risk potential, which must be excluded.
  • the recess in the ceiling pane serves to discharge the exhaust air and the explosion gases, the flow paths then sharing. While in the event of an explosion the explosion gases find their way, for example between the ceiling, flange and ceiling pane of the room cell, the exhaust air flows through the slots, which are provided for this purpose in the cover flange are.
  • the exhaust vents are protected against the ingress of rainwater not only by their outward inclined arrangement, but also by the recess flange, which the Rainwater must skip before it can reach the recesses and thus the interior of the room cell.
  • the invention is thus able to meet the requirements placed on explosion-protected reinforced concrete room cells in a simple manner.
  • the manufacture and assembly of the reinforced concrete room cell according to the invention are comparatively simple, because not only the room cell, but also the cover can be prefabricated in the precast plant and conveniently assembled at the installation site.
  • the recess and cover and the spatial cell are largely symmetrical. Due to the fact that the cover and the recess have a rectangular to square outline, the flow conditions are not decisively changed compared to other possible layout shapes. Since this outline is oriented with its outline parallel to the longitudinal and transverse edges of the ceiling slab or ceiling slab, the measuring and stripping of the recess is made considerably easier.
  • the lid in the event of an explosion by the internal pressure of the room cell, so that the explosion gases can escape subsequent to the recess between the cover flange and the cover plate.
  • the recess and the cover flange a guide of Forming the lid during pressure equalization in the event of an explosion, it is achieved that the lid may rise upwards, but after pressure equalization is returned downward to rest on the ceiling pane. This reliably prevents the cover from flying away.
  • the sealing against rainwater is improved.
  • the top of the ceiling pane is given a slope, which leads to a recess that forms a drain for the rainwater. This ensures that the rainwater cannot normally collect.
  • the collection of rainwater cannot be ruled out if the recess is blocked and there is no drainage during the service life of a reinforced concrete room cell. If e.g. the reinforced concrete room cell is set up in the forest according to the invention, leaves and other foreign objects can clog the recess. Therefore, it is further provided that the top of the ceiling pane is formed with a trough-like depression, so that a certain storage space for the rainwater is available.
  • an emergency drain is provided for the tub. If the precipitation water reaches its maximum level in the tub, the emergency drain ensures that the accumulated precipitation water cannot overflow the recess flange. Since the emergency drain is therefore located above the tub floor, it cannot be blocked by foreign objects.
  • the ceiling tile must also be protected against the ingress of rainwater by a seal.
  • the embodiment according to claim 6 is therefore expedient.
  • a steel tray is used for sealing, which also serves as lost internal formwork.
  • the explosion-proof reinforced concrete room cell is shown with the ceiling pane 2 of particular interest here, which is designed as a flat plate. Except for function-related openings, the room cell is a cuboid-shaped reinforced concrete box that is closed on all sides, the walls and floor of which are made of panels. 1 shows parts of the longitudinal walls 3, 4 which are welded to one another with the transverse walls 5, 6 in the corners 7 to 10 of the rectangular plan.
  • the ceiling tile is placed on a cornice 11 and in turn, as shown schematically at 12, welded to the rising wall panels.
  • the ceiling pane 2 has a recess 14 which is closed with a cover 15.
  • the cover 15 has a circumferential cover flange 16 which extends essentially orthogonally to the plane of the cover.
  • the recess in turn has a substantially perpendicular upward protrusion above the top 17 of the ceiling plate 2 Recess flange 18.
  • the cover 15 lies loosely with the end face 19 of its flange 18 on the top 17 of the ceiling plate 2.
  • the interior space 25 of the room is supplied with supply air.
  • the exhaust air flows according to the arrows 26 in Fig. 3 through the recess 14 then between the end face 27 of the recess flange and the inside 28 of the cover and exits through the slots 24 into the atmosphere.
  • the flange 18 cooperates with the flange 16. The result of this is a guide which ensures that after the overpressure in the room cell 1 collapses, the cover 29 falls back into the starting position as soon as its weight overcomes the counterpressure. It can be seen that, therefore, the lid 15 cannot get out of the guide even in the case of strong internal explosions.
  • the cover 15 and the recess 14 are rectangular, as is the layout of the room cell.
  • the outline of the cover 15 and the recess run parallel to the longitudinal edges 31 and 33 over the transverse edges 32 and 30 of the ceiling plate 2. This results in a desired symmetry along the intersecting center lines of the transverse and longitudinal edges.
  • the top 17 of the ceiling pane 2 is recessed in the form of a tub. It forms the bottom of the tub.
  • the tub edges are formed by the rising legs of the cornices 11.
  • the tub designated 34 in FIG. 3 is, as shown schematically here at 35, made of sheet steel.
  • the trough is also excluded and in turn has a flange 36 which surrounds the recess 14.
  • the tub serves to collect rainwater, which is arranged through a recess 37 in a tub rim 38 assigned to the deepest of the slope of the tub.
  • the recess 37 is normally lined with a pipe which is connected to a vertical drain pipe which is fastened to the outer wall of the room cell.
  • the liquid level in the tub 34 rises during heavy rainfall until it reaches the level of a further opening 39, which is also located at the deepest slope of the tub, but above the main drain 37 is provided as an emergency drain.
  • the opening 39 lies below the maximum level of the liquid in the trough 34. The maximum level is given by the upper edge 40 of the cornice 11.
  • the steel trough 35 can be used as lost inner formwork of the recess 34.
  • the cover is expediently transported separately from the ceiling pane 2 of the reinforced concrete room cell 1.
  • the cover can be placed on the recess 14 from above.
  • the cover itself is made of reinforced concrete and can therefore be prefabricated in the precast plant as well as the panes of the room cell.
  • Fig. 1 it is shown that the recess flange 18 has a plurality of slot-shaped openings 41. These enlarge the flow cross-section and help to remove exhaust air and explosion gases more quickly.
