Definitions
- the present invention relates on the one hand to a method for suspending false ceilings, in particular, but not exclusively, from false ceilings in tunnels, according to the preamble of patent claim 1.
- the invention relates to a device for carrying out the method according to the preamble of patent claim 2.
- an intermediate ceiling is hung between the tunnel vault and the tunnel carriageway slab in order to separate the tunnel cross-section used by traffic from the cross-sections used by the ventilation and ventilation ducts and the other infrastructure ducts.
- the safety requirements placed on the suspensions used are very high.However, it must be ensured that even in the event of extraordinary occurrences and loads, the false ceiling does not fall onto the road surface, thereby endangering or even killing tunnel users.
- the suspension In addition to ensuring the safety of tunnel users, the suspension must also have a durable construction.
- the present invention is therefore based on the object of providing a method and a device for suspending false ceilings which meet all current and also expected future legal requirements.
- the suspension according to the invention should also be controllable and replaceable and not load-bearing Show welds. Furthermore, the pretensioning of the hanging rods and the non-destructive testing regarding corrosion by means of potential measurement should be guaranteed.
- FIG. 1 schematically shows a cross section through a tunnel vault 1, into which an intermediate ceiling 3 is suspended above the carriageway slab 2, parallel to it.
- the cavity between the tunnel vault 1 and false ceiling 3 is, as usual, through a vertical partition 4 in a ventilation and a ventilation channel 5, respectively. 6 divided.
- the false ceiling 3 is suspended from the tunnel vault 1 by means arranged in the intermediate wall 4 in the form of devices 7 according to the invention.
- the lateral connections 8 of the false ceiling 3 to the tunnel arch 1 are not taken into account in the context of the present invention, although they are important for the safety of the entire construction also play a significant role.
- the device 7 according to the invention for hanging the false ceiling 3 on the tunnel vault 1 essentially consists of three units, namely one upper anchoring 9 in the tunnel vault 1, a hanging unit 10 in the intermediate wall 4 and a lower anchoring 11 in the false ceiling 3.
- the structural details of these three units are discussed in more detail below in connection with FIGS. 2 and 3.
- the upper anchor 9 essentially consists of an advantageously cross-shaped anchor bracket or pot 12 embedded in the tunnel vault concrete, to which a threaded sleeve 13 is connected, which extends into the area of the lower boundary of the concrete tunnel vault 1, where it with a lower end plate 14, advantageously by means of a screw 13 c, is connected.
- the end plate 14 is used, inter alia, in the manufacture of the tunnel arch 1 to nail the upper anchor 9 onto the formwork of the tunnel arch 1 by means of nail holes 15 provided for it.
- the end plate 14 serves as a stop for a pipe section 17 provided with a flange 16 and attachment by the pipe section 17 by means of set screws 18 which can be screwed into blind holes 20 provided with internal threads. Washers 19 are advantageously used for this purpose.
- connection of the anchoring bracket 12 with the threaded sleeve 13 is advantageously carried out by means of a threaded bolt 21 which, on the one hand, into an upper internal thread 13a Threaded sleeve 13 is screwed and on the other hand, the anchoring bracket 12 is screwed from above by means of a nut 22 and a washer 23.
- a flexible hose 26 is advantageously inserted into these concrete parts, which extends from inside the pipe section 17 down to a lower one, which is described in detail below Anchoring 11 connected pipe 27 extends.
- the lower anchor 11 which is embedded in the false ceiling 3 from below, essentially consists of a housing 28, advantageously with lateral reinforcing ribs 29, which serves as a receptacle for a ball joint plate 30.
- the latter is intended for interaction with a hemisphere 31 through which the hanging rod 24 passes and against which it is braced by means of a clamping nut 32 and advantageously a washer 33 and a lock nut 34.
- the inside diameter of the tube 27 is chosen to be larger than that of the pipe section 17 and on the other hand, a seal 37 between the tube 27 and hose 26 is provided.
- the housing 28 of the lower anchoring 11 is advantageously not axially symmetrical to the longitudinal axis of the hanging rod 24, but advantageously has an extension 38 on one side, which makes it easier to attach the wrench screwing the hanging rod 24 and tightening the clamping nut 32 and the lock nut 34 is used.
- a cover 40 is provided, which is advantageously provided in threaded blind holes 41 in the lateral reinforcing ribs 29 screw-in self-tapping screws 42 can be screwed tightly onto the housing 28 from below.
- the invention makes it possible to accommodate the suspension of the false ceiling 3 on the tunnel vault, completely isolated from the environment, essentially within concrete parts, but without this making it impossible to check the load-bearing hanging rods 24. It is also essential that the invention enables each hanging bar 24 to be individually pretensioned and loaded with a predetermined load when the false ceiling 3 is suspended. As mentioned above, the invention also makes it possible to a certain extent to compensate for angular errors which can arise, in particular, from an incorrect positioning of the upper anchor 9 in the tunnel vault 1, without compensating for the supporting parts.
- the device according to the invention is economical because even with varying Hanging height can be worked in a wide range with the same type of hanging bar.
- the person skilled in the art further recognizes that the ability to pretension the hanging rods 24 prevents the partition 3 from tearing off in the region of the tunnel arch 1 even in the event of fluctuations in load. As a result, it may be possible to dispense with the application of a putty joint 43 at this point.
- the device according to the invention fulfills all the requirements placed on suspensions for false ceilings in tunnels and ensures that no load-bearing welds are present and that all parts of the false ceiling suspension that are critical in terms of safety can be checked at any time with relatively little effort and non-destructively. It is economical and enables the individual parts to be largely standardized. It can also be used without problems with a false ceiling 3 designed as a vault, which increases the safety of the entire construction.
