DE10253311A1 - Platform raising and lowering process for rail tracks etc. involves fitting hydraulic press upside down to anchor plate on structural body and punch passing through aperture - Google Patents

Abstract

The platform raising and lowering process involves fitting a hydraulic press upside down to an anchor plate on the top of a structural body or components. The press punch (11) or elongated punch (14) passes through an aperture with feed tube in the anchor plate (6), pressing down onto a fixed foundation, thus lifting the entire body resting on the punch.

Description

In recent years, Construction of platforms from the respective building authorities to a greater extent so-called modular platform systems required. These systems consist of prefabricated or prefabricated Semi-finished parts that turn into complete systems on construction sites be put together.

Some of them have a finished surface, some will the finished surfaces from rubbers applied after assembly.

In contrast to conventional ones Systems can the finished systems in a shorter Construction time are created, but are usually more expensive.

Recently, the operators of railway systems when tendering the necessary construction work often requires prefabricated systems in a later change the entry heights in the wagons can also be lowered or raised at the Bahhsteighhöhe can.

Systems previously proposed go assume that the support points in such cases later from spacers below added or should be removed. It should be from below using hydraulic Presses raised the entire platform system and the necessary spacers laborious removed or inserted become. This is for the required work of the entire railway company for the corresponding Interrupt track. Raising the respective platform segment using heavy cranes is also possible but bothers with electrical traction, the entire operating sequence.

Even when lowering or lifting with heavy cranes the work space under the construction is not in many cases sufficient. Further complex auxiliary structures are then required. The existing track position is deformed by this work. subsequent Track work is afterwards necessary.

The task of those described below Invention is the disadvantages and difficulties described above to avoid, possibly lowering and increasing without impairment the track position and surfaces perform and rail operations during to maintain the renovation period.

According to the invention, all renovation work from the platform surface executed the use of heavy equipment not necessary. The existing surface is retained.

The ending assumes that in primarily systems with a final surface covering built-in, where the covering and single-grain mortar Strength of 8 cm and where the length of the segments is between 6-10 m.

The ends of the individual segments lie on foundations ( 1 . 2 . 2 . 1 . Fig. 10 ), which preferably consist of at least two parts. When assembling a new platform, the foundation parts are secured against being moved among themselves.

If the platform is to be raised, either another foundation part is inserted or the existing part is replaced by a stronger one. When lowering, either a foundation part ( 2 ) removed or replaced by a weaker one (2.1). The foundation parts to be installed and removed are opened through an opening ( 3 . 10 . 5 ), in or out of the running plate. This service opening is already provided during the construction of the platform and by a concrete slab ( 3.1 . Fig. 8 . 9 ,) covered.

The strength of the concrete cover is that Adjusted running plate. The concrete cover sits firmly in the running plate.

The joints between the running plate and cover are covered by the final surface covering ( 4 ) covered. This surface covering is laid in single-grain mortar, which may lead to surface water penetrating into the joints to the next drain and prevent freezing up. The covering is firmly in the single-grain mortar. Next to the lid is an anchor plate ( 6 . 2 . 5 . 8th . 9 . 10 ) in the surrounding concrete using threaded sleeves ( 12 ) is embedded. The anchor plate has an opening in the middle, ( 7 . 5 u. 10 ) with d = 70 mm. There is a tube piece on the anchor plate ( 8th ) welded on as a guide tube for a stamp ( 11 . 14 . Fig. 2 . 8th ) with a slightly smaller diameter. This stamp extends from the top edge of the support plate ( 30 ) to the top edge of the platform foundation ( 1 . Fig. 7 ). On the anchor plate (6) is a housing ( 9 ) ( 2 . 7 . 8th . 9 ,) attached with a hydraulic cylinder. This hydraulic cylinder is supported against the housing when pressure is upwards ( 9 ) and down against the stamp above ( 11 . 14 ) When the pressure increases, the hydraulic ram moves ( 11 . 14 ) downward. The running plate with the connected side members connected to it ( 13 ) ( 8th . 9 ) pulled up.

The hydraulic presses are set up so that the pressure is simultaneously applied to all cylinders ( 9 ) can act, the printing of the stamp ( 11 . 14 ) is down on the foundation ( 1 ) submitted. If you press the stamp again ( 11 . 14 ) the bottom plate connected to the housing ( 30 ) pulled up to the desired height.

After removing the foundation parts to be replaced ( 2 . Fig. 9 ) the running plate can be slowly lowered until it is back on the support blocks ( 1 . 2.1 ) rests.

Then the lifting device must be removed, the foundations, the concrete cover ( 3.1 ) and insert the covering removed at this point in single-grain mortar.

Everyone else is the same Raise or lower segments of the platform.

Existing lines need to lowering and lifting are not taken out or secured.

The attached drawings 2 - 12 ) show lifting and lowering processes on platforms with different heights and designs.

1 shows the section through a platform with an intact but too low platform edge in the normal version.

2 shows the same platform after the elevation by in-situ concrete with the foundation ( 1 ) and the opening ( 3 ) with the inserted lid and the lifting bar ( 52 ) as a finished part. The increase bar ( 52 ) secures with its embedded oarlocks ( 54 ) against tipping to the track.

The old covering was removed. At the top is the riser bar with the hooks of the anchor bars ( 55 ) held in the in-situ concrete. The anchor iron is covered on the top with the single-grain mortar. The anchor bars are covered with PE film, which prevents the in-situ concrete from connecting to the holding or anchor bars so that they can be easily removed later. The separating film laid on the underside of the in-situ concrete slab and pulled up on the lifting beam ( 60 . Fig. 2 . 7 ,) prevents a connection of the in-situ concrete with the base and the lifting beam ( 52 ).

To further increase after 3 was a higher end bar ( 53 ) with holding oarlocks ( 54 ) for pre-drilled holes and upper connecting irons after which the existing end bracket ( 70 ) and the existing end bar ( 52 ) have been removed. In 2 is that afterwards through the opening 3 introduced upper part of the foundation 2.1 to see. The running plate ( 30 ) lies on the upper part of the foundation after lowering 2.1 on 4 shows the push-up plate ( 30 ) before inserting the upper part ( 2.1 ) You can also see the end angles that have already been re-applied ( 70 ) and the hydraulic housing ( 9 )

5 shows the top view of the opening ( 3 ) and the position of the inserted parts ( 2.1 ), the anchor plates ( 6 ) with housing ( 9 ), Threaded sleeves ( 12 ) and the position of the openings ( 7 )

6 u. 7 correspond essentially to the figures ( 3 and 4 )

8th and and 9 show a platform with side members and escape niches where the thinner foundation parts ( 2.1 ) by stronger ( 2 ) have been replaced.

To increase the stamp ( 14 ) the load of the platform segment acting on them in each case on the foundation ( 1 ). The stronger foundation parts ( 2 ) were through the opening ( 3 ) and with the ( 11 and 12 ) the scissor lift devices shown in principle are retracted and lowered into the designated dowel holes.

Out 6 is the location of the openings ( 3 ) between two segments, the location of the sub-foundations ( 1 ), the position of the anchor plates ( 6 ) with openings ( 7 ) to see.

Raising or lowering platforms according to the procedure described above is primarily for platforms according to ( DE 42 05 192 C2 ) thought. According to this method, it is also possible to raise or lower modular platforms of other systems. However, the prerequisite for this is that the finished foundations also permit lowering. In addition, the weight of the platform must be borne with sufficient certainty by the foundations

If these requirements are met, openings are cut out at the ends of the running plate, parts to be replaced via them ( 2 . 2.1 taken out and taken in.

Cut-out parts made of concrete with a finished surface are later inserted and grouted. Anchor plates ( 6 ) with guide tube ( 8th ) must be attached before the lowering or lifting process. For hydraulic stamps ( 11 . 14 ) lead-through openings ( 7 ) are attached to the running plate, which are later closed and grouted again.

The method is particularly suitable for platforms that have a firm but too low edge. ( 1 - 7 ). In such cases, the increase is made using a local concrete slab ( 30 ) with a final panel covering. A later lowering on foundations brought in before the elevation ( 1 ) is carried out using the support stamp ( 11 . 14 ). It should be noted that the in-situ concrete slab with recesses ( 3 ) according to 5 is provided, over the foundation parts ( 2.1 ) can be exchanged. Anchor plates ( 6 ) with casing ( 8th ) must also be provided for the hydraulic stamp.

To connect the existing surface ( 4 ) with the in-situ concrete ( 30 ) is to avoid a release film ( 60 ) to insert. Recesses in the in-situ concrete slabs have a concrete cover ( 3.1 ) close. They must not have any connection with the surrounding in-situ concrete. The concrete cover closes with the top edge of in-situ concrete. Reinforced concrete beams ( 52 . 53 ) on the edge 65 to hang up the inlaid oarlocks ( 55 ) in the pre-drilled holes in the platform edges ( 50 ) to grab.

The oarlocks make it easier to remove the attached front edges later, which are only anchored to the in-situ concrete slab using pulling irons. The attached front edges are secured with anchoring bars ( 55 ) secured in grooves in the in-situ concrete slab.

When the elevated platform is lowered, the attached edge angles ( 70 ) removed, the raised edge raised using a small lifting device and possibly by lower, (52, 4 )) also fitted with oarlocks and retaining anchors.

The lifting and lowering system described can be used advantageously for lifting smaller - medium use older bridge structures. According to the prior art, it is customary to concrete bridges with a lower clearance height at a higher level and to lower them later on the abutments after the concrete has hardened. The lowering takes place via presses, which are built up on the abutments and which slowly let the bridges slide on support benches and bearings.

With the system described, bridges can be lowered continuously onto the supports from above. For this purpose, openings ( 3 ) in the support plate, through which the hydraulic stamp ( 11 . 14 ) can be led up to the support benches. Before lowering, the bridge must be connected to the hydraulic presses by means of embedded anchor plates or corresponding fastening so that the bridge is fully on the stamps when the hydraulic or support plunger is extended ( 11 . 14 ) rests. When the hydraulic pressure slowly decreases, the bridge sinks to the bearings.

The hydraulic rams are then removed and the existing openings like that concluded that she to a later one Time reopened and can be used.
