Definitions

  • the invention relates to a tubular spiral staircase with a tubular steel spindle on which radial steps are cantilevered.
  • the invention also relates to an arrangement of a plurality of tubular spiral staircases of this type arranged one above the other.
  • Such tubular spiral staircases made of steel are particularly attached to the outside of buildings as escape stairs or as retrofitted stairs. With such stairs, good corrosion protection is essential due to the weather conditions.
  • the present invention has for its object to propose a tubular spiral staircase made of steel, to which the treads can be attached in a radially cantilever manner and in the case of largely factory-made prefabrication nevertheless guarantees perfect corrosion protection, for example by hot-dip galvanizing, without weak points is, and the transport of the prefabricated parts and the installation is unproblematic.
  • the tubular spiral staircase according to the invention should be flexible.
  • the tubular spindle provided with welded-on supporting elements has only a relatively small space requirement, so that hot-dip galvanizing is also possible in smaller or medium-sized plants.
  • the transport of such a pipe spindle with support elements does not require vehicles of particularly large dimensions, and installation on site is also possible with simple aids without construction cranes due to the lower weight. Only on site must then or the like after installation and attachment of the pipe spindle on the building. the individual steps, pedestals, etc. are installed, whereby no drilling work is required as a result of appropriate preparation and there is therefore no risk of damage to the corrosion protection.
  • An advantageous embodiment of the tubular spiral staircase according to the invention is characterized in that two flats made of flat steel are provided per step, which form a star shape from the tubular spindle in the area of the outer surfaces of the steps extend outwards, and that the stiffly designed treads between these tabs, or covering them outward, are fastened by screw connections and project in the radial direction, projecting beyond the tabs. At least one stiffening web is welded between the tabs to ensure good transverse stability.
  • two stiffening webs are fed in between the tabs at a distance from one another, of which the inner stiffening web arranged in the region of the pipe spindle serves as the upper support surface and the outer stiffening web welded in the area of the outer boundary of the tabs serves as the lower support surface of the step.
  • the forces exerted by the radially projecting step are absorbed by the two stiffening webs, so that additional screw connections between the steps and the tabs can be reduced to a minimum.
  • the two tabs arranged at a distance from one another and the two stiffening webs arranged between the tabs are already welded together to form a prefabricated carrier cassette before being welded to the tubular spindle.
  • Such carrier cassettes can then be prefabricated in series production and then only have to be welded to the pipe spindle in accordance with the dimensions of the tubular spindle staircase in the corresponding angular position and at the appropriate distance from one another before the whole is given its corrosion protection.
  • Such tubular spiral staircases are usually also provided with a platform at the upper end in order to have a corresponding exit into the upper building level or the like. win, and also to anchor the pipe spindle to the building.
  • a likewise corrosion-protected, in particular hot-dip galvanized, platform frame is provided which, on the one hand, has a clamp for attachment to the upper end of the tubular spindle for the purpose of support and, on the other hand, has brackets for attachment to a building or the like. is equipped.
  • the tubular spiral staircase according to the invention is normally set up for one floor height in buildings and thus extends in one piece over such a height.
  • such tubular spiral staircases are arranged one above the other, according to an advantageous embodiment of the invention, the tubular spindles are connected to one another at their ends by clamps and are simultaneously supported on the building side.
  • the clamp provided in the presence of a platform frame can simultaneously serve to connect the pipe spindles arranged one above the other.
  • FIG. 1 and 2 are only intended to explain the basic structure of a tubular spiral staircase, namely a tubular spiral staircase with cantilevered treads 3 attached to a tubular spindle 1.
  • the like provided concrete slab 13 or the like. gets up and is fastened there.
  • the upper side of the pipe spindle 1 is supported on the building in a suitable manner.
  • a platform 2 is also provided at height h, from which there is an exit to the upper building level.
  • the platform 2 is also used in the present example for fastening the pipe spindle 1 to the building by means of indicated fastening screws 12.
  • tubular spiral staircase shown in FIGS. 1 and 2 with the full length of the treads 3 protruding from the tubular spindle 1 in a star-shaped manner, requires considerable space and is heavy in weight and is therefore difficult to transport in this configuration, and especially not in one Pieces can be immersed in the bath of a hot-dip galvanizing system.
  • FIGS. 3 and 4 from a tubular spiral staircase of the type according to FIGS. 1 and 2 shows the following special features: for each step, a supporting element is welded to the tubular spindle 1, which consists of two brackets 4 that extend approximately radially apart from one another consists of flat steel.
  • the tabs 4 are stiffened in the area of the tube spindle 1 with a welded-on web 6, and this web 6 is also used for fastening to the tube spindle 1.
  • the radial length of the tabs 4 is approximately 40-50 cm, while the radial length of the steps 5 e.g. 1.5 - 2 m.
  • the treads 5 consist of U-shaped pimpled, corrugated or teardrop sheet.
  • the steps 5 are placed over the tabs 4 and include them.
  • the Attachment takes place by means of bolts which are inserted through bores 14.
  • two tabs 9, which are spaced apart from one another, are also welded to the tubular spindle 1 approximately radially.
  • these tabs 9 are connected to one another by two webs 7 and 8 for the purpose of stiffening.
  • This construction has particularly good transverse stability.
  • a step 10 is arranged, which in the present case is designed as a grating. 5 shows that the inner web 7 arranged in the region of the pipe spindle 1 is welded to the tabs 9 at the top, while the web 8 welded to the other end of the tabs 9 is attached at the bottom.
  • the step 10 is now inserted between these two webs 7 and 8, and it can be seen that if the step 10 protrudes beyond the length of the tabs 9, the forces occurring between the webs 7 and 8 are absorbed without being transmitted of the forces from the step 10 to the tabs 9 special precautions would have to be taken. In theory, a bolt connection in the area of the bore 15 would suffice, however, for safety reasons, several connections will be made at different locations.
  • the embodiment according to FIGS. 5 and 6 permits rational prefabrication of the support element for the steps 10.
  • the tabs 9 are welded to the stiffening webs 7 and 8 and form a prefabricated support element.
  • such supporting elements which can also be referred to as supporting cassettes, are then welded to the tubular spindle 1 in the corresponding angular position and height. This preparatory construction can of course also take place in the embodiment according to FIGS. 3 and 4.
  • FIGS. 3 and 4 show the welding points between the individual parts.
  • the tabs 4 are welded to the web 6 by welding points 16, while the supporting element 4, 6 produced in this way is then connected to the pipe spindle 1 by welding points 17 and 18. Similar welds are found in the embodiment according to FIGS. 5 and 6, the welded connection between the tabs 9 and the web 8 not being shown for the sake of clarity.
  • FIG. 7 shows in a simplified representation how a pedestal frame 20 can be attached to the tubular spindle 1.
  • the platform frame 20 has a corresponding shape depending on the size of the platform plate to be placed and fastened thereon (not shown) and has at one end a clamp 21 which can be placed around the pipe spindle 1 and fastened to it by screwing.
  • Corresponding brackets 22 are arranged on the other side of the platform frame 20, with which the platform frame can be fastened on the building side. In this way it is possible to support the pipe spindle 1 with respect to the building at a certain distance and at the same time to allow a support for a platform plate for exiting to the higher building level.
  • Both the platform frame 20 and the platform plate to be placed on are provided with corrosion protection, in particular by hot-dip galvanizing.
