Definitions

  • the invention relates to a method for creating and / or connecting a staircase with integrated elevator shaft on or in an existing building, in particular on or in a residential building, preferably for barrier-free connection of the building to the staircase to be created. Furthermore, the invention relates to a staircase created by the method according to the invention.
  • Multi-family dwellings in particular large multi-family dwellings with six or more dwellings per dwelling account for less than 10% of dwelling buildings, but accommodate a good third of dwellings.
  • the urban area in comparison to the rural area, has a much higher proportion of housing. This increased share is due to the densified residential development. For example, in Berlin only about 1.7% (about 317,000) of all German residential buildings, but still about 4.6% (about 1.8 million) of all apartments in Germany. Germany is still a tenant nation, the rental rate is 54.2%. Like the proportion of housing in urban areas, the rental rate is also much higher than in rural regions (cf. Statistical Offices of the Federation and thelonged - Census 2011 ).
  • the housing situation of elderly people (older than 65) in Germany is as follows: around 45% of them live in owner-occupied residential property, 48% live in rented houses and around 7% live in other types of housing (for example in in-patient care facilities).
  • older people tend to live in older residential buildings.
  • 17.3% of all German households live in buildings built after 1991, while for households aged 65 and over the proportion is only 5.3% (see Seventh Report on the Situation of the Older Generation in the Federal Republic of Germany).
  • the particular buildings affected by the invention result from the construction of the post-war period, in particular in the fifties and sixties.
  • the construction of the post-war period was very much geared to functionality. This was in the multi-storey housing, in addition to the poor energy insulation also by the fact that the basement was usually made to protrude from the ground.
  • the present invention is therefore an object of the invention to provide a method by which an existing building is adapted by simple means such that a barrier-free access is possible.
  • the individual method steps of the method according to the invention need not necessarily be in the order in which they are shown in claim 1. Rather, the method steps can also be performed in a different order and / or or at least partially simultaneously.
  • the elevator shaft can also be a shaft for a lift.
  • the elevator shaft frame may also be designed as a lift shaft frame.
  • the steps of the method according to the invention can be repeated in order to produce a predetermined or desired number of floors of the staircase, for example, until at least all living levels have been developed. The number of storeys of the existing building and the staircase do not have to match.
  • the lowest level of the existing building (basement) and / or the top level of the existing building (attic storey) could not be connected to the new staircase.
  • the lowest floor of the stairwell and the lowest level of the existing building need not necessarily coincide.
  • the underlying object can be achieved in a surprisingly simple manner by creating a staircase with integrated elevator shaft in or on an existing building, namely on the part of the building where the existing façade is open and an existing staircase is at least partially dismantled.
  • the building may, in a particularly advantageous manner, be a building, in particular a residential building, with a half-storey staircase.
  • a barrier-poor or barrier-free development of the individual floors or apartments is achieved in a simple manner.
  • barrier-free is not necessarily interpreted in accordance with the German Industrial Standard applicable on the filing date. Rather, this is to be understood as a dismantling of existing barriers, so that the existing building corresponds, for example, to senior-friendly or barrier-poor requirements.
  • the inventive method is characterized by the fact that no intervention in the apartment floor plans of the existing building necessary and an extremely short construction period is to be estimated. Impairments for the tenant and resulting rent reductions are minimized.
  • an interim staircase can be built, for example on the side of the existing building facing away from the entrance. It is essential that access to the apartments via the interim staircase via the already existing on this side of the building balconies of the apartments can be done, for example, via arcades. In particular, with a simultaneous energetic renovation of the building, the existing balconies can be cut to achieve a thermal decoupling. Alternatively, existing window holes could be increased, especially to the extent of a floor to ceiling window, to then commit the apartment through this new approach. Such a procedure is particularly advantageous if there are no existing balconies. The newly created window could, if it is no longer needed as access, get a French balcony as fall protection.
  • the existing balcony door can be complemented by a lockable door in an advantageous manner.
  • the existing facade can be opened, especially windows, concrete parts and other components are dismantled.
  • the existing staircase runs and existing semi-pedestals are free.
  • a roof opening can be made in the area of the existing staircase house.
  • additional security measures can be taken to keep the roof stable.
  • an emergency roof to protect against rain can be kept. Through the resulting openings later disassembled concrete parts can be lifted.
  • the structural conditions are checked and if necessary precautionary measures are taken before the start of the work. Then you can start the dismantling work.
  • dismantling it is advantageous if the work on the top floor begin and floor by floor are continued down until the lowest floor, for example, the basement floor or the ground floor is reached.
  • the existing staircase runs and existing semi-pedestals can for example be cut out and / or pricked out.
  • the concrete parts can be transported with a lifting device from the building body.
  • the first part to be dismantled may be the inventory staircase which leads from the topmost half-platform into the top floor.
  • the existing staircase run which leads from the top half platform to the next lower floor, can be dismantled.
  • the top stock semi-pedestal can be dismantled.
  • the procedure is repeated at the next lower stock half-podest, until finally all inventory halfpods and stockpile runs are dismantled.
  • the excavation can be done with the production of the foundations. Subsequently, a base plate can be cast, whereby possibly Dämmself be carried out below the bottom plate.
  • the staircase outer walls in masonry construction and / or as finished parts such as precast concrete elements and / or wooden elements - for example, a board-stack construction - can now be built.
  • the staircase exterior walls need not necessarily be realized as a closed construction.
  • these can also be constructed as a frame construction, in particular as a steel frame construction.
  • the staircase frame may be formed in one piece or consist of at least two parts that are delivered to the site and placed on the outside walls of the stairwell.
  • the frame parts can for example be screwed together and connected non-positively with the stairwell outer walls.
  • the term staircase frame is to be understood in the broadest sense, this may be formed as an integral part of the staircase exterior walls.
  • the stairwell frame may also be a ring anchor.
  • the ring anchor could also be formed in one piece.
  • the ring anchor could be cast, for example made of concrete.
  • securing support measures can be taken.
  • An essential task of the staircase frame is to stiffen the exterior walls of the stairwell and to divert forces into the existing structure.
  • a staircase frame is arranged, if necessary, can be dispensed with a staircase frame altogether.
  • the hall construction could now be mounted.
  • the first fastening elements can be arranged on the exterior walls of the stairwell and / or the stairwell frame and on the stock podium at the same height.
  • a U-profile with, preferably welded, bracket or a double-T-profile or IPE profile, in particular non-positively is connected to the pedestal ceiling in front of the apartments in front of the apartments.
  • the Fixing elements for example, be designed as a pure U-profiles or as a double-T profile or IPE profile.
  • a second fastener in particular a U-profile or a double-T-profile or IPE profile.
  • the existing staircase side walls can be staked in twice the height of the second fastening elements or the second U-profiles in order to create a statically relevant support, should this be necessary after examination of the static conditions.
  • the second U-profile can then be placed first on the already mounted staircase outer frame. If the free-abutted region is advantageously more than twice as high as the second U-profile, it can now be carefully inserted behind the existing frame construction in the region which has been freed on both sides of the existing outer wall. Finally, the second U-profile can be submerged and optionally connected non-positively with the outer frame construction. In general, any profile shapes for the first fastening element and the second fastening element are conceivable.
  • Fire protection regulations must be taken into account, which may vary depending on the different building classes. For example, it may be necessary to apply additional non-flammable planking to all combustible structures (e.g., wood-panel exterior and shaft walls, structural solid wood (KVH) ceiling structures). It is also conceivable that no more inflammable materials may be installed, in this case, the stairwell outer walls and elevator shaft walls can be designed as precast concrete parts and the KVH be replaced in the ceiling structures by steel beams.
  • combustible structures e.g., wood-panel exterior and shaft walls, structural solid wood (KVH) ceiling structures.
  • KVH structural solid wood
  • the elevator shaft walls are at least the lowest floor of the staircase, ie at least built between the lowest floor and the floor above and possibly attached to or on the elevator shaft walls, a hoistway frame. It is conceivable that the elevator shaft walls in the lowest floor, for example, in the basement or on the ground floor of the existing building, are placed on previously leveling thresholds. In the floors above it is possible to lift the elevator shaft walls on the To make elevator shaft walls and / or the elevator shaft frame of the underlying projectile.
  • the elevator shaft walls can be designed in wooden element construction - for example as a board-stack construction.
  • the hoistway walls may be at least partially or completely made of masonry and / or precast concrete parts and / or steel.
  • the hoistway frame may be integrally formed due to its smaller size, with a multi-part, in particular two-part design is possible.
  • the individual frame parts can be screwed together, for example.
  • the term hoistway frame is also to be understood broadly, so that it can also be formed, for example, in one piece with the hoistway shaft walls.
  • the elevator shaft frame can be realized in particular as a ring anchor. By the elevator shaft frame also a stiffening and a derivative of external forces is ensured. Depending on the statics, an elevator shaft frame does not have to be provided on each floor; if necessary, an elevator shaft frame can be dispensed with altogether.
  • the staircase outer walls and the elevator shaft walls and / or the elevator shaft frame and the stairwell frame can be connected to one another via connecting elements, in particular non-positively.
  • this connection can represent the boundary of the new floorboards in the staircase and on the other hand can serve as a support for the staircase construction.
  • the prefabricated staircase construction may be a steel tube staircase or a dissimilar material.
  • the staircase construction per projectile can consist of one or more parts of the staircase, for example three staircase parts. These stair parts can be bolted on site and connected non-positively with the stairwell exterior walls and elevator shaft walls.
  • a deck of emergency steps and emergency platforms can be installed on the staircase construction be applied to allow an immediate inspection of the staircase, so that the stairs can be used during the assembly process, but the subsequent staircase does not take damage.
  • the later covering of the stairs can be put together as follows: Steps and risers can be covered with a refractory covering, eg a stone covering.
  • a refractory covering eg a stone covering.
  • the soffits of the staircases in the area of the staircases and the corner platforms do not have to be clad, but they can also be easily provided with a refractory cladding if required by fire protection.
  • ceiling or floor elements can be introduced both on the fastening elements and on the connecting elements.
  • These may be beams (e.g., KVH or steel) placed in the direction of the bulkhead walls between the two already mounted profiles or U-profiles.
  • the beams in the same running direction as the beams in the corridor, between the stairwell frame and the connecting elements between the stairwell frame and elevator shaft frame can be inserted.
  • a panel e.g., OSB panel
  • the carriers could be laid in the opposite direction.
  • the profiles would not be set on the stock podium (rear) and the building exterior wall (outside), but would be fixed to the existing ceilings on the left and right, for example dowelled.
  • the profiles could also be wooden or other support, due to the smaller span.
  • the steps of the method according to the invention can be repeated until a predetermined number of floors has been reached for the stairwell. It is possible that the exterior walls of the stairwell outside the basement (lowest floor) are made in Holzelementbauweise. The remaining steps are carried out analogously to the underlying projectile. The same applies to all subsequent floors. After the top floor has been created in the manner described, a possibly existing emergency roof can be dismantled and the roof can be closed. It It is expressly pointed out that the exterior walls of the stairwell and / or the elevator shaft walls can also extend over more than one floor, in extreme cases over all storeys.
  • a door element or a door or a partition comprising a door element could be erected in the transition between a corridor of the existing building and the staircase.
  • the partition could be made of the same material as a staircase exterior wall or as an elevator shaft wall.
  • the partition and the staircase exterior wall or the elevator shaft wall need not be made of the same material.
  • one of these components could be placed in the wooden frame and the other or the other components are bricked. This ensures that the staircase does not have to be included in the energetic building envelope in an energetic calculation. This advantage is especially in a steel frame construction of the staircase exterior walls.
  • the staircase could be realized in such a way that it is to be included in the energetic building envelope.
  • a ramp or a flat bed can finally be used as a local measure to enable barrier-free access to the ground floors.
  • an additional holding station of the elevator is realized at the level of the entrance of the existing building, so that a barrier-free access to the elevator is provided even without a landfill and a bypass of the at the height of Incoming inventory lying stock pest is possible.
  • barrier-free access to the lift creates barrier-free access to all floors.
  • all floors can be accessed barrier-free.
  • the inventive method can be equipped with an extremely compact design, an existing building with a staircase, which includes a lift.
  • an existing building with a staircase which includes a lift.
  • the underlying object is further achieved according to claim 15 by a staircase, which is produced by the inventive method.
  • the method according to the invention has or can have a device-specific form.
