Definitions
- the invention relates to a method for erecting or dismantling, in particular, a supporting scaffold for a heavy load according to the preamble of claim 1 or claim 4.
- Such support structures for heavy loads can be dimensioned with external dimensions in length and width between 25 and 35 meters and a height between 100 and 200 meters, which are used, for example, in coal Power plants are used to carry boilers as heavy loads. These boilers, which have a total weight of up to 10,000 tonnes, primarily generate steam to drive turbines in the power plant. These boilers hang in anchor rods at a height of up to 150m above the ground, depending on the type of power plant.
- the invention is therefore based on the object of developing a method for the assembly or dismantling of supporting scaffolds and also of such boilers, by means of which supporting scaffolds in particular can be assembled or dismantled in a simple and correspondingly cost-effective manner and disposed of in an environmentally friendly manner.
- This object is achieved according to the invention by the features of claim 1 with the method for construction, claim 4 with the method for dismantling and claim 11 of a system.
- the method according to the invention is characterized in that both the construction and the dismantling of a supporting scaffold are possible in the same way, but in reverse order.
- the lowest level of the supporting structure is erected around the support by at least one crane on the ground area and a first lifting system is mounted by the crane on top of the erected lowest level of the supporting structure and connected to the support to hold the latter in a liftable manner.
- the support is then lifted together with the at least one crane within this installed level of the supporting structure by the installed first lifting system and the second lowest level of the supporting structure is built onto the level created by the at least one crane.
- a second lifting system which is mounted by the crane on top of the erected second level of the supporting structure and connected to the support to hold the latter in a liftable manner.
- the first lifting system on the lowest level is then uninstalled and the support with the crane on it is lifted up one level by the second lifting system. This process is repeated with the individual levels being mounted one on top of the other until, preferably, the entire supporting structure is constructed.
- a lifting system preferably a strand lifting system
- the at least one crane is lifted from the floor area to the top of the supporting structure and moved onto the flat support at the upper end of the supporting structure.
- a first lifting system preferably a strand lifting system
- the support is then separated from the supporting structure surrounding it and gradually lowered within the supporting structure by the first lifting system together with the at least one crane on it.
- the lifting system can be a known climbing crane, by means of which the individual parts of the lifting system for lifting the crane are transported to the top of the supporting structure.
- a mobile crane of average size can be used, a large number of which are available at any time and which are also cost-effective to use.
- a second lifting system is mounted on top of the subsequent lower second level of the supporting structure and connected to the support to hold the latter in a lowered manner. This allows the first lifting system and the first level of the supporting structure above the support to be dismantled or removed by the crane.
- a third lifting system is mounted on top of the subsequent lower third level of the supporting structure and connected to the support for lowering the latter, and the second lifting system and the second level of the supporting structure can be dismantled by the crane in the same way. This process of dismantling the individual levels of the supporting structure is then repeated until, preferably, the entire structure has been dismantled.
- supporting scaffolds with the massive support pillars, cross supports and frames can be dismantled and dismantled step by step without having to carry out blasting or use large cranes, which would have to have a total height greater than the supporting scaffold before dismantling.
- the lifting system by means of which the crane is lifted from the ground area to the upper end of the supporting structure is also used as a lifting system for the subsequent lowering of the support.
- the lifting systems are conveniently installed on the top in the corners of the steps, which are rectangular in cross-section and are stacked one on top of the other, and their movable tension elements are detachably attached to the support on the inside of the supporting structure so that the latter can be lowered one step at a time in a controlled manner.
- Fig. 1 is a perspective schematic side view of a supporting structure of a system according to the invention with an external lifting system and a crane before lifting;
- Fig. 2 is a perspective schematic partial side view of the supporting structure according to Fig. 1 with the support and the crane standing thereon as well as a lifting system;
- Fig. 3 is a perspective partial side view of the supporting structure according to Fig. 2 with lowered support and the crane standing on it as well as two mounted lifting systems on top of the two steps shown;
- Fig. 4 is a perspective partial side view of the scaffolding according to Fig. 3, with the top step and the lifting system on it removed;
- Fig. 5 is a perspective partial view of the supporting structure according to Fig. 3 without the crane with a view of the two mounted lifting systems on top of the two second and third stages shown; and
- Fig. 6 is a perspective side view of a lifting unit of the lifting system without supporting frame.
- Fig. 1 to Fig. 5 show a schematically illustrated support structure 10 for at least one heavy load, which is mounted inside the support structure 10 but is not shown in more detail.
- This support structure 10 is made up of several steps 15.1, 15.2, 15.3 to 15.n, which are rectangular in cross-section and identical on the outside of the top and bottom steps.
- This support structure 10 can be assembled in different ways depending on the circumstances and requirements and can be placed free-standing in a work area or designed as part of a building with a different number of steps.
- a support 11 is attached to the surrounding frame 13, which is usually designed as a grid.
- the support structure 10 can also be designed differently than shown, which can have a different cross-sectional shape instead of a rectangular or square one and can be provided with other tension elements.
- Such support structures 10 are used, as mentioned, for carrying heavy loads such as boilers in coal-fired power plants and can have external dimensions of between 25 and 35 meters in length and width and between 100 and 200 meters in height.
- Such a boiler can have a total weight of up to 10,000 tonnes and is primarily used to generate steam to drive turbines in the power plant.
- a lifting system 20 is first mounted on the top of the supporting structure 10 on laterally projecting beams 14 and with it the at least one crane 25 is lifted from the floor area 19 to the top of the supporting structure 10 and adjusted to the operating position on the support 11.
- the lifting system 20 consists of four lifting units 21 which are arranged above the beams 14 in such a way that they can be fastened to a platform 26 on the outside with their vertically extending tension elements 22 and lift the latter to such a height that their upper standing surface can be positioned flush with that of the support 11.
- a mobile crane is used as crane 25, which can be moved onto this platform 26 and which is lifted together by means of the lifting system 20 from the outside from the floor area 19 to the top of the supporting structure 10 and the crane 25 can be moved from the platform 26 to the support 11.
- the Crane 25 has a crawler vehicle 27 and a telescopically extendable boom 29 with at least one support cable and a crane hook 29' attached to it.
- a stationary or adjustable crane with a vertical lattice mast and at least one lattice mast placed transversely on it or something similar could also be used.
- Two or more cranes 25 of the same or different size could also be placed on the support 11 and could work at the same time.
- At least one or more support cables are provided with the crane hook 29' at the front end with such a length that they can lower the parts 31 dismantled during dismantling from the uppermost step 15.1 down to the floor area 19 outside the support structure 10.
- the support 11, now held by the lifting system 20.1 is separated from the supporting structure 10 surrounding it at the connection points and is lowered by this lifting system 20.1 together with the crane 25 within the supporting structure 10 around the first level 15.1 to below the upper frame 16 of the second level 15.2.
- the connection points between the support 11 and the frame 13 of the supporting structure 10 in the operating state are not shown in detail.
- a second lifting system 20.2 is then mounted on top of the subsequent lower second stage 15.2 of the supporting structure 10 and connected to the support 11 for lowerable support of the latter, so that the support 11 and the crane 25 located on it are held by the latter.
- the first lifting system 20.1 is dismantled and the first stage 15.1 of the supporting structure 10 above the support 11 is dismantled by the crane by holding it and by lowering the dismantled parts 31 down to the floor area 19, as can be seen from Fig. 4.
- these parts 31 can be cut by welding.
- the support 11 is lowered by the second lifting system 20.2 into the third stage 15.3, as shown in Fig. 5.
- a lifting system 20.1 is mounted on the upper frame 16' at the subsequent lower third stage 15.3 of the support structure 10 and connected to the support 11 for lowerably holding the latter.
- the second lifting system 20.2 is then dismantled and the second stage 15.2 of the support structure 10 is dismantled into these parts 31 and removed by the crane 25.
- This process of dismantling the individual stages 15.1 to 15n of the supporting structure with the respective step-by-step lowering of the support 11 is repeated preferably until the entire structure has been dismantled.
- the lifting system 20.1 used first on top of the first step 15.1 is reused as the third lifting system 20.1 on top of the third step 15.3 after dismantling and connected to the support 11 held by the second lifting system to hold the latter in a lowerable manner.
- the two lifting systems 20.1 and 20.2 can thus be installed and dismantled alternately. However, it is not impossible that more than two lifting systems are used.
- Fig. 5 shows the largely dismantled first stage 15.1 as well as the second and partly the third stage 15.2, 15.3 before dismantling.
- the four lifting units 21 of the respective lifting system 20.1, 20.2 are above the Frames 16, 16' are attached in the corners of the rectangular steps 15.2, 15.3. They each consist of a support element 23 arranged on the respective frame 16, 16' in its corner area, a hydraulic piston-cylinder unit 30 fixed to the latter and the tension elements 22, 22' guided through it.
- the four support elements 23 are each arranged transversely in the corners 36 of the frame 16, 16' so that the tension element 22 runs vertically on the inside of the support structure 10 and can be fastened at the lower end to a holding element 11 'in the corner of the rectangular support 11.
- Two tension elements 22 are arranged in pairs next to one another in the third stage 15.3 and are fastened to one holding element 11', with the tension element 22 of the upper lifting unit 21 being fastened to the holding element 11' offset inwards so that it runs at a distance inwards from the support element 23' of the lower lifting unit 21.
- the upper lifting system 20.2 can then be dismantled so that the support is only held by the lower lifting system 20.1.
- these lifting units 21, consist of strand lifting systems according to Fig. 6, each of these hydraulic piston-cylinder units 30, which are fixed to the support element 23 provided with flanges 33 and have a central through-opening on the inside for receiving one or more tension elements 22, preferably made as strands.
- the cylinder is provided with an annular chamber in which the sleeve-shaped piston is guided in the axial direction.
- a clamping device with radially adjustable clamps for holding the Tension elements 22 are provided.
- the method according to the invention further provides that it can also be used to construct a support structure 10 in the same way, in which this is done in the reverse order to the dismantling.
- This process is not illustrated in detail, but is carried out by the following essential steps.
- the reference numerals for the components which are essentially the same are given: a.
- the at least one crane 25 is placed in the operating position on a flat support 11 in the floor area 19. b.
- the preferably lowest level 15.n of the support structure 10 is then placed around the support 11 by the at least one crane 25 on the floor area 19 and a first lifting system system 20.1, preferably a strand lifting system, is mounted by the crane 25 on the top of the preferably lowest level 15.n of the supporting structure 10 and connected to the support 11 for lifting the latter as explained above. In principle, this lowest level could also be mounted by a different crane and the crane 25 only be used from the second or third level onwards. c.
- the support 11 is then lifted together with the at least one crane 25 by the mounted first lifting system 20.1 within this mounted level 15.n of the supporting structure. d.
- auxiliary devices could be used for assembling the beams 14 and the lifting system 20 before dismantling, which could be lifted and assembled using temporarily usable cable winches or other lifting devices.
- the support 11 on the top of the supporting structure which is usually designed as a grate, can be provided with base plates, which could also be assembled using these lifting devices.
- the lifting system could be equipped with a different number of lifting units 21 and tension elements 22 than those shown, for example only with two lifting units.
- the steps are each provided with an upper frame on which these lifting units are placed. However, they could also be built without a frame and the lifting units 21 could then be attached to a respective support pillar or to another supporting element of the supporting structure.
- Hoist systems powered pulleys, climbing cranes and/or similar could be used as lifting systems.
- the crane could also be lifted without platform 26 and be equipped with additional hoist winches to enable the required lifting length of the supporting cable(s).
- a building could also be dismantled or rebuilt using facade elements, lattice masts for high-voltage electrical lines or the like.
- the support pillars 12 to be assembled, the frames and the cross supports of the supporting structure could not be lifted by the crane 25 from the ground area to the top level during assembly or, conversely, could not be lowered by this crane from the top level to the ground area, but a lifting system that can also be moved on the supporting structure, similar to the lifting system 20 shown in Fig. 1, could be used, by which the parts could be lifted up, while the crane 25 removes these parts from the lifting system for assembly. Conversely, during dismantling, the parts would be lifted by the crane onto the lifting system and then lowered to the floor area.
- a lifting system could be designed like an elevator lift with pulleys for the cable pull.
