Definitions
- the invention relates to a self-supporting wooden staircase with a free-hand railing load-bearing starting posts, end posts and, if applicable, turning posts, the steps of which the not released side with bolts protruding in its extension or directly on a wall or cheek.
- a staircase is unsupported if its Steps are only anchored on one side or not at all in an adjacent wall.
- Stairwells or for connecting individual living floors to each other are common self-supporting, spiral wooden stairs with a railing on the self-supporting side used, the steps of which are held on the wall with bolts or directly on the wall.
- On the cantilevered side are the steps to stabilize the stair construction either firmly connected to each other, suspended from the railing or both.
- the connection of the Steps among themselves must be such that each step is the next lower step on the free side supports or supports the next higher level.
- the start and end stages are often directly on the load-bearing railing posts screwed on.
- the wooden railing posts have the disadvantage that the screw connections with the floor ceiling and the steps due to the high pressure load and since the wood when drying, it shrinks, gives way and its seat is loosened. The result is that the wooden staircase bends too much and starts to vibrate. With such structures it is therefore, the bolts on the load-bearing railing posts are required from time to time check and tighten if necessary.
- the object of the invention was therefore to improve on the prior art cantilevered wooden staircase with a stable connection of the supporting posts to the To create floor ceilings and the steps at which the load-bearing railing posts stand on Desire can be relatively thin and at the same time sufficient stability guarantee.
- Suitable metal supports for this are metal pipes, solid material bars, metal profiles, T supports, Double-T beams or the like. Beams made of steel or stainless steel are best suited, however, other metals such as aluminum are also suitable.
- the profile of the wearer should be chosen so that it gives the metal beams high rigidity and flexural strength gives. For example, round, quadrangular or polygonal hollow profiles are also suitable open profiles, such as T, double T, L, U or S profiles.
- the supporting railing posts with the same or greater stability be designed considerably slimmer.
- the metal support with an essential U-shaped or tubular cladding made of wood or imitation wood encase.
- the cladding can be designed so that it simply over the metal support pushed and screwed or glued to the attachment. This is how a Wooden posts with a stabilizing, load-bearing metal core.
- the attachment of the start and end posts to the respective floor ceilings can be done on different ways.
- the lower end of the metal carrier is in indentations or holes in the respective Floor ceilings sunk or recessed.
- the recess in the floor ceiling can for example, an opening that is already recessed when pouring a concrete ceiling, or also an opening subsequently drilled hole.
- the recess can be used for a positive fit of the Metal carrier to be adapted to its shape at the lower end, however, the metal carrier also cemented into the ceiling or otherwise permanently attached to it.
- the beam can still be used Metal plates or brackets screwed to the respective floor ceiling or otherwise be connected.
- the metal supports are at a distance from the lower end Metal plates or brackets with holes for screwing on the top of the ceilings welded on. But it may also be appropriate to use the metal carrier exclusively to connect such metal plates or tabs to the respective floor ceilings.
- the metal supports point at their lower end perpendicular to their longitudinal axis arranged mounting plates with holes.
- the metal beams are then directly on the ceilings screwed on.
- Metal supports for end posts can also be on the side of the Floor ceiling, from which the wooden staircase runs down, be fastened.
- the metal beams in this case, they are either only screwed to the side of the ceiling or otherwise attached or both laterally and vertically from the metal support protruding fastening tab additionally fastened to the top of the floor ceiling.
- the Lateral fastening of a metal support to a floor ceiling can be done with screws or Bolts are made that extend through the entire metal support to the ceiling or over Metal plates or tabs that are welded to the side of the support.
- the wooden staircase according to the invention is expediently constructed so that the individual steps the next, above levels are suspended. For this you use suitably a bolt through the entire thickness of the lower step and a spacers provided between the two stages up to or through the upper stage extends. For static reasons, it may be appropriate if all or part of the stages are suspended from the handrail and / or the railing underflow. Such a suspension gives the wooden staircase according to the invention additional stability and relieves the connection of the individual levels with each other.
- the metal carriers are in adjustable in length. This can be very useful, especially for turning posts Tolerances that can occur during assembly of the wooden staircase according to the invention, balance.
- the wooden staircase according to the invention is a main carrier part with a different from its upper End of downwardly extending internal thread, and a second support member is over arranged the upper end of the main part and with the main part via a screw that can be screwed into or out of the internal thread of the main part, in Distance adjustable connected.
- the second carrier part can be designed so that the Screw is accessible and adjustable from the top of the second support part.
- the the lower end of the second carrier part is expediently designed like a sleeve in which the lower main part of the beam, regulated by the screwing depth of the screw into the internal thread, can slide in and out.
- Figure 1 is a self-supporting, spiral wooden stairs 1 with steps 5 and 6 and one on the Self-supporting side arranged railings shown.
