This application is the national stage of PCT/DE2006/001045 filed on Jun. 20, 2006 and also claims Paris Convention priority to DE 10 2005 030 333.1 filed on Jun. 29, 2005.
The invention relates to a climbing shoe of a climbing formwork for fixing to a concreting section of a building which retains a climbing rail guided along the wall of a building to be erected in pre-erected concreting sections. Climbing shoes are known which embrace a climbing rail in such a manner that on the one hand, they are displaceable in the climbing shoes and on the hand the climbing rails are held in a guided manner on the wall of a building. If the climbing shoe is to be removed from the wall, the climbing rails must be withdrawn from the climbing shoes and then it is possible to dismount the climbing shoes which are affixed at provided anchor points of a concreting section.
It is the object of the invention to provide a climbing shoe which can be removed from a stationary fixing on a concreting section even when a climbing rail passes therethrough.
The object is achieved by a climbing shoe which comprises a sliding shoe part on which claws are provided which hold a climbing rail disposed displaceably between the claws in a guided manner, whereby the claws embrace partial sections of the climbing rail and wherein at least one claw is provided in a pivotal and/or telescopic manner on the sliding shoe part.
If one claw on the sliding shoe part is configured pivotally and/or telescopically on the sliding shoe part, the climbing shoe according to the invention among a plurality of climbing shoes attached to a building can always be removed from a wall when it is no longer required in use for the provided climbing formwork. This is always the case when one concreting section is completed and a new concreting section is to be erected. The climbing rails used for the climbing formwork have a length greater than the height of two concreting sections to be erected. Consequently, the lowermost climbing shoes must always remain on the wall to be erected until the climbing rails have climbed so high that they completely release the lowermost climbing shoes. When the climbing rails are out of engagement with the climbing shoes, these climbing shoes can be dismounted. Auxiliary platforms or follow-up platforms are usually required for dismounting this climbing shoe known from the prior art and a fairly large supply of climbing shoes is required for the correct operation of a climbing formwork known from the prior art so that the known climbing formworks can be operated.
If climbing shoes according to the invention are used, additional follow-up platforms are superfluous for dismounting climbing shoes which are no longer required because these climbing shoes can be dismounted from a wall whilst they are still in engagement with the climbing rails. If necessary, the climbing shoe according to the invention can also be attached at an arbitrary position on a climbing rail. All the advantages obtained during dismounting of a climbing shoe from a climbing rail can be applied to the mounting of a climbing shoe on a climbing rail.
A particular embodiment of a climbing shoe makes it possible to dismount the climbing shoe if two claws of a climbing shoe embrace the climbing rail in partial sections of the climbing rail and one claw is fixed pivotally on the sliding shoe part. A pivotal bearing can be formed simply and cost-effectively on a claw of the sliding shoe and the pivoting movement can be stopped extremely simply by means of a locking bolt. When the locking bolt is removed, the claw can be pivoted out and removed from the climbing rail. When the claw is pivoted out, it can also be blocked by means of the same locking bolt so that it is ensured that during dismounting of the pivotal claw, said claw does not pivot uncontrollably.
If the climbing shoe according to the invention is configured as a sliding shoe part and as a wall or slab shoe part which are detachably connected to one another by means of a horizontally aligned stub shaft, dismounting of a climbing shoe is even simpler because it can be additionally divided in addition to the pivotal claw.
In a further embodiment of the invention, the climbing shoe has a vertically aligned axis in the wall shoe part. This has the advantage that the climbing shoe can also be aligned at rounded walls of concreting sections in such a manner that adjacent climbing shoes always align the climbing rails held in the climbing shoes and the consoles associated therewith parallel to one another. This has the advantage that carriages, which accommodate formwork walls, for example, can be driven towards the wall or driven away from the wall on the consoles or rails.
In the following figures, the climbing shoe according to the invention is shown and described in an embodiment.
In the figures:
The figures show the embodiments according to the invention highly schematically and should not be understood as being to scale.
The same functional elements are largely characterised by the same reference numerals in the figures described hereinafter. These functional elements can be configured substantively differently.
A climbing cylinder 26 is placed on the sliding shoe part 16 of the climbing shoe 10. Of the climbing cylinder 26, only the lowermost part of the cylinder can be seen which adjoins a housing 28 via which the climbing cylinder 26 is placed on an articulated shaft 30 of the climbing shoe 10. A safety bolt 32 fixes the housing 28 on the articulated shaft 30 without hindering the pivoting region of the climbing cylinder 26 about the articulated shaft 30. When the safety bolt 32 is pulled against a spring force from engagement with the articulated shaft 30, the climbing cylinder 26 can be withdrawn from the articulated shaft 30. The housing 28 of the climbing cylinder 26 is supported on a housing wall of the sliding shoe part 16 by means of a rubber or viscous elastic element 33.
The sliding shoe part 16 is connected to the wall shoe part 18 in an articulated manner by means of a horizontally aligned stub shaft 34. The sliding shoe part 16 can be pivoted about the stub shaft 34 with respect to the wall shoe part 18.
Inside the sliding shoe part 16, the catch 22 can be pivoted about a pivot point 36 against the pressure of a spring 38 in the anticlockwise direction.
If the catch 22 is not weight-loaded by means of the bearing bolt 24 of the climbing rail 20, the catch 22 can be pivoted manually by means of the lever 40 against the pressure of the spring 38 into the sliding shoe part 16. This is necessary whenever the climbing rail 20 is to be moved downwards with respect to the fixedly arranged climbing shoe 10.
Only small sections of the concreting section 14, the climbing rail 20 and the climbing cylinder 26 are shown in the figure.
When the climbing rail 20 is moved by means of the climbing cylinder 26 in the direction of the arrow 42, a bearing bolt 24 of the climbing rail 20 presses onto an approach slope 44 of the catch 22 and pivots the catch 22 about the pivot point 36 against the pressure of the spring 38. At the same time, the catch 22 pivots into the sliding shoe part 16 of the climbing shoe 10.
When the climbing cylinder 26 is retracted, the bearing bolt 24 rests on the catch 22 and the climbing shoe 10 holds the climbing rail 20 in the position shown in the Figure on the wall 12 of the concreting section 14.
A tab 52 is shown on the sliding shoe part 16 and carries the articulated shaft 30. A climbing cylinder can be placed on the articulated shaft 30.
If a climbing shoe 10 on a wall 12 of the concreting section 14 is to be dismantled or dismounted in the presence of the climbing rail 20, a claw 50 of the sliding shoe part 16 can be pivoted open if the locking bolt 56 is brought out of engagement from a rigid wall section of the sliding shoe part 16 and is withdrawn from an opening in the claw 50. When the unlocking is released, the claw 50 can be pivoted about the axis 54. When the claw 50 is pivoted open, the locking bolt 56 can be inserted back into its position which locks the claw 50 and it is then ensured that the claw 50 remains in the state shown in the figure. If the stub shaft 34 is then removed between the sliding shoe part 16 and the wall shoe part 18, by withdrawing it from the common mounting in the direction of the arrow 57, the sliding shoe part 16 can be removed from the climbing rail 20. If necessary, the wall shoe part 18 can then be released from its anchor position in the wall 12 and removed.
A climbing shoe 10 of a climbing formwork for fixing on a concreting section 14 of a building comprises a sliding shoe part 16 on which claws 50 are provided. At least one claw 50 is provided pivotally and/or telescopically on the sliding shoe part 16.
