Definitions
- the invention relates to a protective door device for air protection systems and atomic power plants, with a door opening located in a wall, which is preferably designed as a concrete wall, and a protective door that can be closed and overlapped by the door.
- a protective door device should be resistant and tight against a shock wave of ten bar (as a reflected shock wave), it should also withstand the subsequent suction wave while maintaining its seal. It is precisely the short succession of stresses in two alternating directions caused by the shock wave on the one hand and the suction wave on the other that places high demands on the mechanical strength.
- a protective door device for air protection systems and atomic power plants which can withstand a reflected shock wave of 10 bar pressure while maintaining its seal and the subsequent suction wave and can be produced inexpensively.
- a protective arrangement for air-raid protection systems and atc are power plants with a door opening located in a wall, preferably a concrete wall, which is bordered on all sides by this wall and a protective door which overlaps this door opening, the protective door having a central locking and has a shell-shaped, metal door leaf stiffened by ribs, from which support arms for a door hinge protrude in one piece on one long side and two bolts for holding two door hinges are inserted in the wall on the one hand next to the door opening and on the other hand pockets for the adjustable one in the door opening Intervention of locking bars of the central locking system are arranged.
- the door leaf is cast in one piece from aluminum using the casting or die-casting process or from steel. Its strength against the reflected shock wave in particular is given on the one hand by its convex shape towards the pressure side, which is due to the shell shape, and on the other hand by the stiffening ribs. No frame is used, rather the door leaf is arranged on door hinges that are provided directly in the wall by means of two bolts.
- the door opening is bordered on all sides by the wall, so it does not border on the floor or other surfaces - as is the case with room doors, for example.
- the door opening is preferably rounded, in any case not angular.
- An oval shape is particularly preferred, oval being understood here to mean, in addition to an egg shape, in particular a shape which is delimited by two semicircles and straight lines connecting them (oval of a stadium).
- the door leaf When the shock wave attacks, the door leaf is pressed against the outer wall around the door opening. During the subsequent suction wave, the door leaf is held by means of the locking rods, their engagement in the pockets can be adjusted so that the seal can also be maintained during the suction phase.
- the engagement areas of the locking rods are held elastically in the pockets.
- a spring is preferably provided which preloads the relevant ends of the locking rods in a direction which runs transversely to the main surface of the door leaf. A cushioning in other directions transverse to the longitudinal direction of the locking Gel rod is advantageous.
- the door leaf is preferably oval, in any case it has a 180 degree rotational symmetry. In this way, only a single door leaf has to be manufactured, which can be used for right and left hinges.
- the door leaf preferably has a smooth, spherical or spherical-cylindrical outer surface that forms an overlap area on the edge, by which the door leaf is larger on all sides than the door opening in the wall.
- the seal is arranged on the side of the overlap area facing the wall.
- a circumferential rib in the form of a short pipe socket that jumps away from the inside of the door, the outer dimensions of which are only slightly smaller than the inner dimensions of the door opening.
- a stiffening edge protrudes toward the outside, which supports the overlap area so that it cannot be sheared off during the shock wave.
- the essentially Z-shaped arrangement of these two flanges together with the seal located between them has proven to be very advantageous, it gives the door leaf the necessary mechanical strength so that the shock wave can be survived.
- Rib systems connected integrally with it run from the edge of the pipe socket-like rib over the entire inner surface of the door leaf, they meet or branch at a multiplicity of nodes. Roughly generalized, this stiffening by ribs can be described as follows: In the longitudinal direction of the door leaf, three parallel ribs run continuously from top to bottom in its central region, they intersect and merge with three ribs, which are also arranged equally and run from left to right . Between each of these three central ribs and the outer circumferential rib there is a further rib which also runs in a straight line, so that the door is stiffened in the longitudinal direction by five parallel ribs.
- the support arms are double and run towards the door hinge in a V-shape. They are on the outside.
- FIG. 1 shows an interior view of the door leaf of the protective door device
- FIG. 2 shows a horizontal cross section through a protective door device with the door leaf according to FIG. 1
- FIG. 3 shows detail III in FIG. 2 in an enlarged view
- FIG. 4 shows a plan view of the outside of a door according to the invention
- the protective door device consists of a protective door 20, a door opening 24 located in a wall 22 of the system, two hinge arrangements, each with support arms 28 and hinges 30, and a central locking 32, to which pockets 34 in the reveal of the door opening 24 belong.
- the protective door essentially consists of an oval door leaf 36 which is shield-shaped, is convexly curved towards the pressure side 38 (see FIG. 2) and covers the door opening 24 in an overlapping manner in the drawn closed position.
- the door leaf has a substantially smooth, approximately 25 to 50 mm thick shell from the outside (4), which is continuous and is internally stiffened by a rib system, which is described in more detail below:
- a cross runs through a center point 40 Ribs in the main directions of the door leaf 36, to the left and right of this cross at a distance of about 6 cm, additional ribs run, so that a three-rib cross is formed overall that is still stiffened by diagonals in the area of the center 40.
- the remaining four sectors are stiffened by additional ribs.
- ribs are delimited by a peripheral rib 42 which runs around the oval shape. All the ribs are formed in one piece on the door leaf 36 and run into one another at their binding or crossing points without a gap.
- the outer edge of the edge rib 42 essentially delimits the door opening 24, which is only slightly larger than the outer dimension of the peripheral edge rib 42.
- the door leaf 36 covers the door opening 24 all around, as can be seen particularly in FIG. 4 can be seen.
- the closed peripheral rib 42 and some of the inner ribs project so far to the inside of the door (protective side 46) that their free ends lie on one level. All other ribs are shorter and end before this level. With a dimension of the door leaf of 90 by 130 cm, the total height of the edge rib 42 is approximately 20 cm, this rib tapers - like all other ribs - to its free end, where it is approximately 10 mm wide.
- a total of four support arms 28 are attached, which start on the door center line and run in pairs in a V-shape on the hinges 30, the axes of which are arranged approximately at a distance of 15 cm from the adjacent edge of the door leaf 36.
- the paired support arms 28 each end above and below a bearing pin 48, which receives a hinge pin 50.
- the support arm closer to the center point 40 runs in a straight line and at right angles to the longitudinal axis of the door. it attacks approximately in the center of mass of the respective door half, ie the upper or lower door half.
- the second support arm begins a few centimeters below or above the highest or lowest point of the edge rib 42, but on the opposite side.
- the door leaf 36 including its ribs and a total of four support arms 28 is produced in one piece using the casting process, for example from GAlSi 12 or cast steel.
- a stiffening edge 52 projects at right angles to the main plane of the door leaf 36, it gives the part of the door leaf projecting beyond the edge rib 42 so strong that this edge area does not shear off from the pressure side 38 in the event of pressure loads can be.
- a seal 54 which runs in a ring and can be seen in more detail in FIG. 3. From this it can be seen that the seal 54 is essentially a strip of an elastic material. When the door is closed, the area 56 initially abuts the outer surface of the wall 22, this is achieved by an oblique course of the inner surface of the overlapping edge.
- a closing shaft 58 runs through the center point 40 and transversely to the main plane of the door leaf 36 and is guided over a distance of approximately 25 cm and is sealed gas-tight via an O-seal. It forms a square on the pressure side 38, on which an actuating lever or wheel can be inserted. A handle for actuation is permanently provided on the inside.
- the closing shaft 58 is connected to eccentrics 60, on which in turn locking rods are articulated. These are each guided in bearings 62 which are placed on the free ends of the ribs.
- One of the pockets 34 is assigned to each free end of a locking rod.
- the closing blocks 64 are set such that when the closing rods 66 are extended (see FIG. 2), the seal 54 is pressed against the wall 22 over the entire length, as is shown by way of example in FIG. 3.
- the individual adjustment of the closing blocks 34 makes it possible to compensate for unevenness in the surface of the wall 22 and also for inaccurate dimensions of the door leaf 36.
- the pockets 34 are designed as follows: a box 70 is let into the wall 22 and is firmly connected to it, it is made of sheet steel and has a passage opening for the locking rod 66.
- each of them there are two locking blocks 64, which in The direction can be adjusted transversely to the main plane of the door leaf 36 and at the same time is loaded elastically in this direction by means of springs 72, which are designed as helical compression springs.
- the setting is made such that the closing block facing the door leaf 36 presses the free end of the closing rod 66 toward the protective side 46, as a result of which the seal 54 is pressed into contact with the outside of the wall 22.
- the free end of the closing rod 66 can move due to the pressure without shearing off.
- the protective door can withstand high dynamic loads.
- the springs 72 are omitted and instead the free end regions of the closing rods 66 are elastically connected to the rest of the main part of the closing rod 66, so that the free ends cannot be sheared off due to a pressure wave.
- the bearing bolts 48 are inserted into the pipe 22 penetrating the wall 22 outside the actual door opening 24. These pipe sockets are already provided when the concrete body wall is cast, their inside diameter is several millimeters larger than the outside diameter of the bearing bolts 48, so that the door can be adjusted.
- the bearing bolts 48 are screwed onto the protective side 46, and are inserted in a gas-tight manner by means of suitable sealing measures (for example the inner cavity with silicone compound or an O-seal).
- suitable sealing measures for example the inner cavity with silicone compound or an O-seal.
- the axial position of the bearing bolts can be adjusted by replacing a disc 74 arranged between the head of the bearing bolt receiving the hinge bolt 50 and the outer surface of the wall 22 by a disc of greater or lesser thickness.
