Definitions

  • the invention relates to a protection and access device for the protection of workers and to allow access, especially in the construction of building ceilings, with a number of vertical profiles and a directly or indirectly attached to the profiles work platform.
  • Such protective and access devices are used in the construction of structures to secure the not yet provided with a facade outdoor area of buildings and to provide access between adjacent floors of the building.
  • a protection and access device of the type mentioned is, for example, in the WO 01/53630 disclosed.
  • This has vertical beams, which are each attached via jibs on several building ceilings.
  • trim panels arranged to provide a temporary facade.
  • work platforms can be arranged on the carriers between the building ceilings. The device is raised intermittently from storey to storey, with the carriers being guided by the jibs during lifting.
  • the US 4,962,828 discloses a protection and access device having two levels of vertical profiles (inside and outside) and a third functional level (chain).
  • the vertical profiles are guided into each other.
  • a hydraulic drive is provided, the lower extension arm with the inner vertical profile is firmly connected or welded.
  • the construction of the three functional levels is complex and has the further disadvantage that the device has a rather deep design.
  • the invention is based on the idea to broaden the scope of a protection and access device of the type mentioned and to make these independent.
  • the working platform in an upper region directly or indirectly to the vertical profiles, which are preferably all in a single plane parallel to the building contour, is mounted.
  • the protection and access device according to the invention it may be sufficient to provide only two vertical profiles which advantageously define a single plane of vertical profiles.
  • the device according to the invention can not only fulfill a protection and access function for existing building sections, but also provide a working platform for yet to be created building sections.
  • the device according to the invention allows, for example, to work in a safe manner on an already turned-on, but not yet concrete, building ceiling via the working platform attached to the vertical profiles in the upper area.
  • the protection and access device with its cover also provides protection in building a formwork for the building ceiling to be created, on the one hand protection against falling, and on the other hand protection from the weather (wind, heat, cold) and noise.
  • the vertical profiles are guided by cantilever beams, which can be attached to existing building ceilings.
  • all existing vertical profiles can advantageously be guided on cantilever beams, which is an expression of the fact that advantageously only one plane of vertical profiles can be present, and no frame or the like with a further plane of vertical profiles for guiding the vertical profiles of the protective profiles. and access device is required.
  • Under cantilever is understood to mean a cantilevered or fixed beam, which protrudes in the case of the present invention largely horizontally out of the building and at the end of the vertical profiles - preferably directly - out.
  • the detachable from the device according to the invention drive allows trouble-free and rapid lifting of the vertical profiles with the attached components from one floor to the next, without the rest of the operation of the site is affected.
  • This has proved to be particularly advantageous when advancing the vertical profiles in a still to be created building area, since in this case the use of separate hoists not only cumbersome, but also can be dangerous because the hanging of lifting hooks or the like in an (upper) area of Vertical profiles would have to be done in which there is still no secured building section available.
  • the removable drive can be arranged in the context of the present invention at different locations of the device, it has been found to be advantageous according to a development of the invention that the drive between a cantilever and a vertical profile can be attached. This results in a particularly immediate power transmission with low lever arms and a stable support for the drive.
  • At least one cantilever and / or at least one drive has a freewheel mechanism, in particular at least one gravity pawl.
  • a gravity pawl for example, a spring-loaded pawl or another suitable freewheel mechanism can be used.
  • the freewheel mechanism is adapted to engage with suitable portions on at least one vertical profile so that the corresponding profile can be translated in only one direction (upwards).
  • a gravity pawl rests the corresponding profile in the stationary state on the gravity pawl, but can at a feed of the respective profile without manual actuation of the gravity pawl be guided past this, and then again to rest (via another engagement portion) on the gravity pawl.
  • the freewheel mechanism allows a corresponding vertical profile to be automatically secured to a cantilever and / or a drive. Therefore, in the device according to the invention, even when the vertical profiles are advanced, work can be continued below the device, which is not possible with known devices. Furthermore, the freewheel mechanism on the at least one cantilever and / or on the at least one drive allows a stepless adaptation of the device according to the invention to different storey heights.
  • At least one vertical profile has a plurality of projections and / or recesses with which the at least one gravity pawl can engage.
  • these projections and / or recesses are also designed in such a way that not only the at least one gravity pawl but alternatively or additionally also a section of a drive can engage with them.
  • the projections and / or depressions on the at least one vertical profile fulfill a dual function, namely, on the one hand to secure the profiles in the stationary state, and on the other hand to serve as a force application point for a drive during the advancement of the profiles.
  • the working platform is arranged on a side opposite the cantilevers side of the vertical profiles.
  • the arranged in a vertical plane vertical profiles are spaced as far as possible from the building ceilings. This ensures that the "passing" of the device is facilitated on a turned-upper ceiling.
  • "Ausschale firsten” must be taken into account.
  • a guide shoe could be mounted in relatively fresh concrete, while on an underlying ceiling, for example in the case of a design with restressable reinforcements, the operation of the hydraulic tension can be performed.
  • At least two outer vertical profiles and at least one middle vertical profile are provided, wherein at least one bracing is arranged from the middle to at least one outer vertical profile.
  • loads for example, from own weight
  • loads do not have to be introduced into the center of a building ceiling, but at the edges of the building ceiling, where, for example, walls or other stiffeners of the components are.
  • At least one diagonal support can be attached to at least one vertical profile.
  • a diagonal support has proven to be particularly advantageous if the building to be created only a single level (for example, building ceiling) has, since then the vertical beams are guided over a level of Kragkonn and stabilized on the at least one diagonal support. In this way, the Device even before a first building ceiling is concreted.
  • a profile extension preferably in a pivoted state and preferably with a cover extension, can be attached to at least one vertical profile.
  • the device according to the invention can be easily adapted to peculiarities of the construction process or the building to be created.
  • the cantilever beams have in the context of the present invention mainly the function to store and guide the vertical profiles. However, according to a development of the invention, the cantilever beams can advantageously also be used to apply or apply a stage covering. As a result, the invention provides an increase in the work area and an improved level of security with minimal effort.
  • a clearance is formed between at least one vertical profile and a guide on a cantilever beam.
  • the cover which is adapted directly or indirectly to the vertical profiles, can be designed in the most varied ways in the context of the present invention. Thus, for example, it can essentially be provided over the entire area or even over part of the area. According to a development of the present invention, it is further provided that the cover as such is at least partially permeable to air.
  • the device according to the invention in principle offers the possibility to provide several working platforms, it has proven to be a particularly simple and yet drainage technical and safety advantageous principle that according to a development of the present invention, with the exception of the provided in an upper area work platform no other platform are available.
  • Another advantage of the protection and access device according to the invention is that it has a particularly slim design and protrudes only slightly beyond the outer contour of the building to be created. This is achieved according to an embodiment of the present invention, in particular when the vertical profiles, seen in a plan view, are located on a single, largely straight, polygonal or curved line, which is preferably substantially adapted to the building contour.
  • a protection and access device 10 as a preferred embodiment of the present invention is disclosed in U.S. Pat FIG. 1 shown schematically in a plan view and a front view.

  • the building used in the present embodiment for illustrative purposes has a number of already created building ceilings 12.2 and still to be created building ceilings 12.1, which are supported by supports or walls 42. In the following, between the walls or supports 42 in FIG. 1 shown components are described as a unitary device 10, although the device may also be provided in a smaller or larger area of the building.
  • FIG. 1 Device 10 shown comprises two outer vertical profiles 14.1 and two inner vertical profiles 14.2, which carry a cover 18 on its outer side (ie, the side facing away from the building).
  • the vertical profiles 14 may be, for example, aluminum or steel profiles with an open or closed cross-section.
  • the cover 18 is formed in the present embodiment by a plurality of perforated plates, which cover the outer surface of the device 10 substantially completely and due to their perforation to some extent air permeable and / or possibly also translucent.

However, at the beginning of the construction work, it is also possible to fasten cantilever beams 20 only to a building ceiling 12.2 (or another support) and to ensure the stability of the vertical profiles 14 via diagonal supports or the like, not shown here.
  • the vertical beams 14 thus advantageously span at least two existing building ceilings 12.2 and a building ceiling 12.1 to be created, but may also be made longer or optionally extendable by a profile extension not shown in detail here with corresponding cover extension, these extensions being arranged pivotably on the vertical profiles 14, for example can.
  • the cantilever beams 20 are fastened in the present embodiment in each case by means of a cone 36 on the corresponding ceiling, wherein it is advantageous for the cone 36 is an upwardly tapered component, the like is concreted in the ceiling 12 that it can be released from the ceiling after use and continue to be used.
  • the cantilever beams 20 each have a guide 40 which is designed to engage positively in the profile of the vertical beam 14 and to guide it vertically.
  • the guide 40 is formed with a certain play to the vertical profile 14 in order to compensate for building tolerances can.
  • the guides 40 can be constructed in such a way that the vertical supports can be "threaded in and out” in one direction. Alternatively, however, it is also possible to provide the guides 40 with a mechanism such that they can be engaged at any location with the vertical beams.
  • cantilever beams 20 can serve to place or apply a stage covering 38 in the area between the outer contour of the respective ceilings 12 and the vertical profiles 14 or the cover 18 ( FIG. 1 ).
  • the device 10 further comprises a removable drive 22, which in FIG. 3 best seen.
