Definitions

  • the invention relates to an access flooring for a scaffolding with an access door, which closes a passage opening in the access floor and hinged to the access floor connected to the access floor is mounted.
  • the flexible flap When the flap is fully retracted (fully opened), complete and automatic closure of the flexible flap can not be guaranteed, not least because of the inherent weight of its longitudinal segments. Due to its structural design, the flexible flap is also a cumbersome and difficult to handle. Thus, the flap can not be opened by simple pressure against any underside surface portion, but must be extensively repelled by pressure with multiple body sections or a sweeping arm movement to fully release a closed through the flap access opening for the passage of an operator. In addition, the access floor in the production is costly and involves a user-side security risk, because damaged or even broken stiffening inserts of the flexible flap from the outside are not readily apparent.
  • the invention is therefore based on the object to further increase the safety of persons on a scaffolding in connection with access flooring and to further improve the handling of the access door of such access flooring.
  • the force can increase in the region of the opening angle of the access door close to their vertical position in particular stepwise or substantially stepwise.
  • the characteristic of the elastically deformable element has in this case in the region of the opening angle close to the vertical position of the access door on a discontinuous course.
  • a sudden increase in force is also given when the force from the opening angle of the access door close to its vertical orientation with further increasing opening angles of the access door steadily or exponentially compared to the value of the restoring force, which is up to the opening angle close to the vertical position of the Has built through the access door, enlarged.
  • the elastically deformable element has in the latter case a progressive characteristic. Overall, this advantageously ensures that the access door of the access flooring after opening, that is, when no external force (an operator) acts more on the access door, closes reliably and quickly automatically.
  • the (defined / predetermined) opening angle near the vertical position of the flap is preferably between 75 ° and 87 °, in particular approximately 85 °.
  • the force generated in the elastically deformable element is preferably low up to the opening angle of the access door close to its vertical position.
  • the access door is preferably rigid in the direction of its two plane axes, ie in the direction of its longitudinal as well as in its transverse axis. That is, the access door is designed as a board or a plate. It is understood that the board or the plate may have a multilayer structure or a frame. This can on the one hand a possible damage the access door, in particular a crack or a breakage of the access door, can be easily recognized visually. On the other hand, the access door can be fully actuated by an operator by pressure against any underside surface portion in a simple manner to fully release the passageway for the passage of the operator.
  • an access flooring according to the invention in a scaffolding thus significantly increases personal safety, since an active closing of the access opening by persons is not required and therefore can not be forgotten.
  • the risk that a construction worker falls through an open access opening of an access flooring and thereby significantly injured, is reduced to a minimum or is excluded, unless the subject invention is flawed.
  • Often safety regulations require that the access openings in access flooring automatically close after use. This is fulfilled in a simple manner by the access flooring according to the invention.
  • the access door of the access flooring is particularly easy and safe to handle.
  • An advantageous embodiment of the invention is characterized in that the region in which the access door is connected to the access flooring, extends over an edge side of the access door.
  • the substantially rectangular shape of the access door makes the best possible use of the available area of the access floor and, in conjunction with a passage opening adapted to the access door, makes it easier for a person to pass through the access floor.
  • the access door can be opened either in the longitudinal direction or in the transverse direction to the access flooring. Since the elastically deformable element extends only over one edge side of the access door, the person ascending through the access floor has the greatest possible freedom of movement and is not hindered by the elastic element when climbing through.
  • the edge of the access opening has a Randausformung in which the access door is inserted, and wherein the Randausformung is designed so that the surface of the top of the access door without a step forms a level with the surface of the top of the access floor.
  • the Randausformung ensures that the inserted access door along a portion of its edge is supported by the edge of the access opening of the access decking.
  • the dead weight of the access door in the closed state and optionally an additional weight of an object located on the access door or a person on the access flooring is derived and thus relieves the elastic element of these weight forces.
  • Particularly advantageous is an embodiment which has the Randausformung along the entire edge of the access opening, since the weight is now transmitted as evenly as possible to the access deck and the flexible element is no longer burdened with closed access door.
  • the at least one elastically deformable element is formed as an elongated profile of a rubber and / or tough elastic material.
  • Elongated profiles of a rubber and / or tough elastic material such as natural rubber or silicone rubber, can be inexpensively manufactured in many different forms. Such profiles are long lasting with appropriate formulation, not rusting and resistant to weathering and UV radiation. Due to the material used and its construction, elongated profiles made of a rubber and / or tough elastic material bear a lower risk of injury due to pinching, for example in comparison with coil tension springs. Further advantageous can be by the choice of material and / or cross-sectional design of the elongated profile, the elastic restoring force in its deformation and thus the restoring force of the access door depending on their opening angle set well.
  • the elongated profile has a substantially rectangular cross-section.
  • Such a profile can be easily and in many ways connect both with the access door and with the access decking. For example, screw and / or adhesive connections are possible. Rectangular profiles are very cost-effective in various dimensions available as rod products and can be easily adjusted by simply cutting to access openings with different dimensions.
  • the elongate profile has an at least partially V or W or zigzag or wave-shaped cross section.
  • Such a cross-section can ensure that the force required to open the access door for opening angle is close to a vertical position of the access door, for example less than or equal to 80 degrees, low and increases sharply for larger opening angle.
  • the access door of such access flooring can be opened with a very small force of a person ascending, for example, by simply pressing with his hand or head, when the person rises from the bottom up through the access opening.
  • a further elastically deformable element can facilitate the opening of an access door in the sense of an opening aid when such an element is compressed when closing the access door due to the dead weight of the access door and this stored in the elastically deformed element stored force when opening the access door again and thus the opening the access door additionally relieved. If the access door is open almost vertically, it rises the restoring force abruptly, which ensures a fast closing of the access door.
  • elongated profiles in particular with an at least partially zigzag or wave-shaped cross-section, can be used to produce these profiles and materials which have only a low elasticity, since the use of such cross-sections, the effective path length of the deformable region and thus the flexibility of the elongated profile in the transverse direction increases sharply.
  • the outer dimensions of the cross-sectional profile of the elastically deformable element used here rise only slightly.
  • the access ladder according to the invention is characterized in that the access door has along a part of its edge a first groove in which engages the elongated profile with a first portion and that the fürierisbeiag along a portion of the edge of the access opening, which of the first groove along opposite the part of the edge of the access door, having a second groove in which engages the elongate profile with a second portion, and wherein the elongate profile in both the first groove along the part of the edge of the access door and in the second groove of the access deck along the part of the edge of the access opening is held.
  • first groove along the part of the edge of the access door and a second groove along the part of the edge of the access opening ensures a very space-saving arrangement of the elongated profile.
  • the partial regions of the elongate profile engaging in the first and second grooves completely disappear completely in the access door and the access door. If the first and / or the second groove are each arranged within a larger groove, then further subregions of the elongated profile, which are not held by the access door or the access door, can be accommodated in the respective larger groove. This saves additional space and the flexible element is additionally protected from damage by the access door and / or the access deck.
  • the elongated flat profile in the first groove along the part of the edge of the access door and in the second groove of the access flooring along the part of the edge of the access opening by riveting and / or by screws and / or by adhesive bonds and / or by Undercuts is attached.
  • the elongated profile fastened both in the first and in the second groove can not accidentally slip out of the first and / or the second groove when opening the access door. If the profile is fastened in the first and the second groove by means of screw connections and / or rivet connections and / or undercuts, it can be quickly exchanged in the event of a defect, for example due to a fatigue fracture.
  • a preferred development of the access flooring according to the invention is characterized in that the elongated profile undergoes a material deformation when opening the access door, and that in the region of the material deformation at least partially one or more cavities are formed.
  • the force required to open the access door can be influenced as a function of the opening angle. If a stiffer material is used to make the elongated profile, the cavities formed in the profile can reduce the force needed to open the access door.
  • the shape and the position of the cavities can be achieved, for example, that only a comparatively small force to almost vertical opening the access door must be spent and the restoring force increases only at a vertical position of the access door.
  • the at least one cavity is at least partially closed in the direction of the longitudinal sides of the elongate profile.
  • the at least one cavity is at least partially formed by an indentation extending in the longitudinal direction of the elongated profile into the surface of a longitudinal side.
  • indentations for example carried out in the form of indentations on a bottom of the elongated profile, the force required to deform the profile and thus the opening of the access door can be reduced.
  • indentations on the surface of the profile can be realized even after its production with relatively little effort.

Dans une zone du plateau-trappe d'accès où le volet de trappe d'accès est relié au plateau-trappe d'accès, il est prévu au moins un élément déformable élastiquement qui se déforme lors de l'ouverture du volet de trappe d'accès. Cette déformation génère dans l'élément déformable élastiquement une force qui est opposée au mouvement d'ouverture du volet de trappe d'accès et qui augmente brusquement à partir d'un angle d'ouverture α défini proche d'une position verticale du volet de trappe d'accès.
