Definitions
- the invention relates to a support for supporting a building area, with a Kanthal hollow profile having a central part and two end portions, wherein the end portions are arranged telescopically for length variation of the support respectively from open ends of the Kantrohrhohlprofils from the central part.
- Such supports are also referred to as telescopic uprights and often provide height-adjustable heavy duty supports for dissipating vertical loads in temporary support structures.
- the end parts are telescoped out of the central part for height adjustment of the supports or inserted into the central part.
- Such supports are used in particular in the tunnel scarf area to dissipate fresh concrete loads of slab formwork in the subsurface.
- the end portions In a support according to the invention for supporting building areas, with a Kanthal hollow profile having a central part and two end portions, wherein the end portions are arranged to change the length of the support respectively from open ends of Kantrohrhohlprofils out of the central part out telescopically, the end portions each have a round hollow tube profile.
- the inner wall regions of the Kantrohrhohlprofils form guides for the round tube hollow profiles, wherein the round tube hollow profiles can be guided by means of their contact areas in the central part in the longitudinal direction of the Kantrohrhohlprofils for telescoping the end parts.
- a support according to the invention are two round hollow sections, ie hollow sections with a (circular) circular cross-section, as round tube hollow profiles of the end parts (telescopic tubes) with a particular rectangular hollow profile, ie. a hollow profile with particular rectangular cross-section, as Kantrohrgohlprofil forming the central part combined.
- the preferably equal executed round Hollow profiles represent telescopic tubes, which are introduced from both sides in the open ends of a central tube forming rectangular hollow profile.
- the guides and the contact areas can absorb buckling torques over their entire (common) length and thus make possible a statically highly loadable support.
- This combination according to the invention of a plurality of hollow profiles and their positioning with two overlapping areas means that a very favorable static system is formed by the support according to the invention.
- the maximum material cross section of the support lies in the area of the Kantrohrhohlprofils.
- the areas with lower buckling moment load at the column beginning and end have reduced cross sections with the round tube cross sections.
- Round tubes have a higher static load carrying capacity with respect to bearing holes of the aforementioned bolt holes as equivalent square tubes, z. B. rectangular tubes. This allows bore diameter of the bolt holes and bolt diameter of the
- a telescopic upright according to the invention can therefore be made lighter in relation to the prior art with high load-bearing capacity and thus manufactured more cost-effectively.
