Definitions
- pillars have long been known for supporting higher-level construction elements. Usually, these are carried out in the form of columns, which have a uniform cross-section or a suit, ie a taper, from the base to the superstructure. For the support of superstructures with extensive extension a load-split structure with increased span is necessary, which directs forces from a larger area on the pillar, if the superstructure is not self-supporting or dynamic loads occur. For this purpose, the use of crossbars or Auflagerbalken, especially in conjunction with several columns or the use of truss structures is common.
- a spherical casting node is known in which a plurality of attachment flanges are distributed over the surface to allow the connection of struts.
- This casting node is intended in particular for use in truss constructions.
- the disadvantage here however, the costly production and the inflexible design, so the lack of possibility to make later adjustment to the positioning, size and number of Anitatisflansche, since the angle and positions may be different depending on the version of each application.
- the invention is therefore based on the object to provide a pillar, which has an enlarged span and is flexibly adaptable to the circumstances of the particular application.
- Another object of the invention is to achieve the aforementioned object with identical or similar components as possible and the smallest possible space requirement. Side tasks are an aesthetic appearance and cost manufacturability.
- a free pillar hereinafter also generally referred to as a pillar, with the features of claim 1.
- a free pier with a shank, a branching node provided at the upper end of the shank and at least two cantilevers each connected at one end to the branching node and carrying the superstructure at the other end, is characterized in that the branching node has a branching point Dome surface and a number of cantilevers corresponding number of Kragarmanitatien comprises, and that the Kragarmanitatien are arranged such that the center axes of the Kragarmanitatien and the shaft meet at a common point of intersection.
- the dome surface has a shape which is symmetrical at least to a plane passing through the central axis of the shaft symmetry plane or rotationally symmetrical to the central axis of the shaft.
- the symmetrical structure around the center axis improves the force transmission to the shaft, whereby the power flow can be optimized.
- the shapes of the dome surface may have rounded edges and / or z.
- B. be designed as a pyramid or truncated cone. With this training, the areas are simplified, with which the Kragarmanitatien are connected to the dome surface. In the case of, for example, ellipsoidal dome surfaces, a 3D trimming may nevertheless be necessary.
- a particularly preferred embodiment of the pillar is characterized in that the dome surface is formed substantially in the form of a spherical segment, and that the Kragarmanitatien are connected via annular surfaces with the dome surface, whereby the common intersection of the central axes lies in the center of the spherical segment.
- the outlet angle of the cantilevers relative to the dome surface can be set different.
- the spherical segment is a special form of rotationally symmetrical design of the dome surface, can be used as a Kragarmanitatien simple pipe sections and the outlet angle of Kragarmanitatien based on the shaft can be set arbitrarily, at the same time an alignment of the central axes is guaranteed.
- the segment height is less than or equal to the radius, particularly preferably less than or equal to half the radius of the dome surface.
- the minimum height of the ball segment must meet the following condition, however, where h K for the height of the ball segment, r K for the radius of the ball segment and d A for the diameter of the cantilever connection on the dome surface is:
- the dome surface is produced by a forming process from a steel sheet.
- Corresponding methods for forming steel sheets are known per se to the person skilled in the art.
- the advantage of this preferred embodiment is that correspondingly produced dome surfaces have substantially more constant wall thicknesses than, for example, dome surfaces produced by cast steel.
- the dome surface is located in the upper region of the branching node and comprises the connections to the cantilever arms completely. In a further preferred embodiment of the invention, the dome surface is curved upwards and outwards.
- the pillar is characterized in that the cantilevers are connected by means of screw flanges with the Kragarmanitatien. Depending on the span and the ratio of shaft height and overall height of the pier, long cantilevers may be necessary. In order to simplify the assembly and alignment of the cantilever connections to the dome surface here, these are formed separately from the cantilevers. The connection of the cantilevers with the Kragarmanitatien.
- Kragarmanitatien is then via screw flanges, in particular internal flanges, for which, if necessary, a mounting opening must be provided on at least one of the two components.
- the pillars are characterized in that the Kragarmanitatien are integrally formed with the cantilevers. As a result, the number of parts is reduced, which reduces the transport and manufacturing costs.
- the branching node comprises a transition, wherein the dome surface is connected by means of the transition to the shaft, and wherein the transition between different diameters and / or cross-sectional shapes of the shaft and the dome surface compensates.
- the same cross-sectional shapes of the shaft and the dome surface are preferred, usually round or with a polygonal cross-section, although the diameters may differ, in this case in the application with diameter as a designation also the appropriate dimension, such as edge length, Um-, In Vietnamese etc. are included in polygons. Different diameters can be provided, for example, due to the space required on the dome surface for the Kragarmanitatien, if sufficient for the shaft, a smaller diameter for the support load.
- the pillar may be characterized in that the transition has a continuously varying diameter and / or cross section.
- conical transitions for example, which extend the shaft diameter upwards to the diameter of the dome surface, are created for this purpose.
- the transition can also be designed to produce a mushroom-shaped appearance as a solid flat plate or from the upper shaft end downwardly directed cone.
- Embodiments of the pillar are characterized in that the parts of the branching node are welded together.
- these are preferably welded together, in particular the parts of the branching node can be connected to form an assembly, whereby the transport and assembly costs can be reduced.
- pillars may be characterized in that bulkhead plates are provided in the branching node.
- bulkhead plates are provided in the branching node.
- Embodiments of the pillar are characterized in that the cantilevers are designed as a tube with a constant or conical cross section.
- the easiest and most cost-effective way of manufacturing the cantilevers is to produce tubes of constant diameter. Due to the force curve and in view of the design also conically tapered cantilever arms are sufficient, which at the same time enable weight savings.
- Embodiments of the pillar according to the invention are characterized in that the cantilevers are bent or 3D-shaped. Mainly for design reasons or to ensure certain clearances, such as clearance height on a certain width of the span between two pillars, the cantilevers can also have a curved course. Under 3D-shaped cantilevers cantilevers are understood to be deformed whose central axis over the length of the cantilever in more than one direction.
- Pillars of embodiments according to the invention are characterized in particular in that the shaft is designed as a spiral seam welded tube. As a result, just any diameter and tube lengths are possible, which allow a constant or conical cross-sectional profile.
- the outline of the center line of at least two cantilevers is not parallel to the floor plan of the carriageway centerline of the bridge structure.
