Definitions

• the invention relates to a support device for a track section of a roller coaster assembly and to a roller coaster assembly including the same. Furthermore, the invention relates to a connecting element for connecting two segments of a support device to a boom, and to a support device subassembly including the same.
• supports in roller coaster systems particularly as load-bearing structural elements for tracks, is well-known and widespread.
• Steel support columns are typically used, but due to their high susceptibility to vibration in tall roller coaster structures (such as lifts, humps, and/or banked curves), they require one or more bracing elements.
• These multi-section support configurations, known as A-frames therefore require considerable space at their bases. This also increases material requirements and costs.
• Centrifugally cast concrete columns which are conventionally used as radio or overhead line masts, are known from the state of the art.
• Centrifugally cast concrete refers to concrete components produced using a special manufacturing process (the centrifugal casting process). Production is carried out using rotating rollers and steel molds. The rollers, rotating at 600 to 900 revolutions per minute, compact the poured concrete from the inside out due to centrifugal forces at approximately 20 times the force of gravity. Because the excess water drains inwards, while the heavy concrete components are continuously pushed outwards, the resulting concrete has a very low water-cement content, making the centrifugally cast concrete particularly dense and therefore also very strong.
• spun concrete technology provides several advantages of spun concrete technology.
• the long service life of the spun concrete components accelerated construction progress due to factory pre-assembly and the resulting cost savings, as well as improved deformation properties.
• cracking can be further reduced, making the use of spun concrete even more attractive.
• the printed publication describes DE 10 2012 110 184 A1
• a reinforced concrete column for a building structure made of ultra-high-performance concrete (UHPC) with a concrete strength class of at least C115.
• UHPC ultra-high-performance concrete
• Such a column can be formed from several segments, which are connected to each other, for example, by means of a flange connection.
• a flange connection is described in the publication.
• DE 102014 104439 B4 known.
• EP 2 757 213 A2 Furthermore, a foundation for a support is described.
• a support device for a roller coaster assembly comprising a support base of the lowest segment of the support device, e.g., in the form of a base plate for anchoring the support device in a foundation, a support head that can be connected to the track to transfer a static and dynamic load of the roller coaster assembly into the support device and then further into the foundation, and at least one modular segment arranged between the support base and the support head, which extends between the support base and the support head.
• the support structure is designed as a single load-bearing column.
• a segment is referred to as a column base, column head, or intermediate segment, depending on the application.
• At least one segment is designed as a prestressed spun concrete hollow body.
• spun concrete ensures high load-bearing capacity and high overall structural damping of the support structure. This results in low susceptibility to vibration, especially due to vortex excitation phenomena perpendicular to the wind load. Consequently, the support structure can be designed as a single load-bearing column, eliminating the need for additional support beams. This also reduces the space required at the column base, as multi-unit column configurations are no longer necessary (as, for example, with a steel column configuration). The result is an attractive and appropriate design.
• the prestressing of the prestressing steel gives the support structure high stiffness, meaning that, compared to a similar non-prestressed steel-concrete component, less deformation occurs under high loads. This makes it suitable for use in tall structures of roller coaster installations, such as lifts. Furthermore, the production of the segment consumes significantly less material due to the centrifugal concrete construction method.
• the segment can absorb horizontal and vertical load components of the roller coaster arrangement, both in the dynamic and static load.
• the segment can have a conical or cylindrical shape.
• a conical design of the segment further improves the load-bearing behavior, especially when using additional segments designed as intermediate segments, as it follows the distribution of internal forces along the support structure. This results in a structurally optimal shape for the supporting structure.
• the segment can have a taper greater than 5 mm/m.
• the segment, the column base, and the column head can have a diameter ranging from 500 mm to 2500 mm.
• the column head of a column head segment of a 60-meter-long support structure can have a diameter of 800 mm
• the column base of a column foot segment can have a diameter of 2300 mm.
• a force-fit connection of the segment to a segment designed as a column base segment, an intermediate segment, and/or a column head segment can be formed by a flange connection or a butt joint.
• the connection type can be selected according to requirements.
• a segment designed as a support base segment can have a support base at one end and an end plate at a second end opposite the first end.
• a segment designed as a support head segment can have a support head at one end and an end plate at a second end opposite the first end.
• An intermediate segment can have a first end plate at one end and a second end plate at a second end opposite the first end.
• the end plates can be force-fitted to further end plates of another segment.
• the intermediate segment can have a lower and an upper end plate, which are located at a lower and upper end of the intermediate segment, respectively, when assembled, and which can be force-fitted to a lower and upper end plate of another intermediate segment, respectively.
• Construction tolerances can also be compensated for using the end plates and/or the column base and column head. For example, oversized holes in the end plates can be used to compensate for these tolerances. High-strength mortar can be used under a base plate for vertical adjustment of the support structure.
• the column base segment, column head segment, or intermediate segment can incorporate prestressed steel strands running between the end plates of the intermediate segment, between the column base and end plate of the column base segment, between the column head and end plate of the column head segment, or between the column base and column head.
• prestressed steel strands subject the spun concrete to compressive stress.
• steel strands with a diameter of 11 to 15.7 mm are used, e.g., with a strength class of St 1660/1860.
• the steel strands can be anchored by wedge anchorage in an end plate or by immediate bond directly in the concrete.
• the steel strands can be slightly prestressed before the spun concrete application to position them as intended.
• Final prestressing can also be applied in stages; however, it is important that the concrete remains sufficiently flowable at maximum prestress. Long-term effects that lead to prestress loss, such as concrete creep and shrinkage or relaxation, must also be considered in the design calculations. Splitting tensile reinforcement must be additionally provided in the load introduction area. If necessary, additional non-load-bearing steel can be placed in the cross-section.
• the segment can be made of concrete ranging from concrete grade C80 to C180. This ensures that the aforementioned properties regarding load-bearing capacity, vibration resistance, deformation behavior, and service life are maintained.

• the slim design of the segments also results in a high architectural quality for the roller coaster assembly 100.
• the present invention offers the possibility of reducing the space required at the column base, since two- or multi-tiered column configurations of the tall track figures with low lateral load can be replaced by a single strut. This results in an attractive and appropriate design. Furthermore, it is to be expected that spun concrete columns in Compared to composite steel columns, spun concrete columns have a more favorable environmental impact over their life cycle. In addition to the reduced steel usage, the use of reinforcing steel with a high recycled content and the maintenance-free nature of the spun concrete column also positively influence its environmental footprint. Therefore, good public and societal acceptance is expected.
• the manufacturing and overall costs of a spun concrete column can be lower compared to a solid steel column for some roller coaster features. These criteria, combined with a reduction in the footprint at the column base, offer a product that should be very attractive to amusement parks.
• the invention relates to the implementation of spun concrete columns in the amusement park industry.
• the column consists of one or more segments in a cylindrical or conical design.
• the conical design of a concrete column offers optimal load-bearing behavior that follows the distribution of internal forces along the column.
• the length and diameter of the segments are determined by manufacturing and transport possibilities. There is no upper limit.
• the segments are preferably connected by bolting two flange plates together. Other design variations are possible.
• the concrete column is prestressed by spun-in steel strands, which are preferably wedged into the flange plates.
• connection at the base of the support can be made, for example, with a base plate or as a quiver design.
• the required material properties of the concrete for typical applications in roller coaster figures with low transverse loads are in the range up to C100 (100 MPa compressive strength).
• C100 100 MPa compressive strength
• the overall structural damping of this system is significantly higher than that of a solid steel column. This results in lower susceptibility to vibration, particularly in the transverse direction to the wind due to vortex excitation, as well as in the longitudinal direction to the wind.
• Construction tolerances can be compensated for by using oversized holes in the flange plates.
• the column's misalignment is minimized using standard construction methods, within the limits of what is typical for a solid steel column.
• hybrid supports made of multiple materials are also possible, consisting of a lower concrete module and an upper, solid-web steel module. Attaching a cantilever to a concrete segment is possible using steel components, such as a circumferential ring collar. Alternatively, a steel segment in the form of an adapter piece or adapter plate can be positioned between two concrete segments in various configurations. A connecting element designed as an adapter ring plate with a nose section for receiving a cantilever is particularly preferred. A connection can also be made via sleeve rods cast into the concrete module, which allow for a connection to a flange plate attached to the cantilever. Another connection option is a hinged connection or a pre-tensioned bolted connection of the cantilever to a steel blade cast into a segment. These connection methods can be used depending on the requirements.
