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.
- the area in which the access door is connected to the access floor a flexible cover, which covers the at least one elastically deformable element.
- a flexible cover which covers the at least one elastically deformable element.

- Access flooring wherein in the area in which the access floor is connected to the access door, two elastic elements are arranged.
- FIG. 1 shows a perspective view of an access flooring 10 which is used, for example, in a scaffolding and is also designated by the terms “scaffold decking” or "boarding pass.”
- the access decking 10 has a passage opening 12 on the side shown on the left in FIG can be closed.
- the edge 16 of the access opening 12 is formed by a in the direction of the access opening 12 and the access door 14 towards open recess so that when closed access door 14 this rests along its edge on the access deck 10 and the upper edges of the access door 14 are at the same level as the upper edges of the access floor 10. In the event that the access opening 12 is closed, there is thus no edge at the transition between the access door 14 and the access floor 10.
- FIG. 1 shown access door 14 has a rectangular shape. In a region 18, the access door 14 is hingedly connected to the access flooring 10 along one of its longitudinal sides. The connection of Passage flap 14 with the access decking 10 is effected by an elastically deformable element 20, which extends over the entire longitudinal side of the access door 14.
- the elastic element 20 is an elongated profile 22 with a rectangular cross-section.
- FIG. 1 can also be arranged a plurality of elastic elements of other types in the area 18.
- the resilient deformable elements may be spaced from each other in the region 18.
- the access door 14 is connected to the access floor 10 by hinges (not shown in FIG. In addition to hinges as any type of swivel joints can be used.
- the elastically deformable element can additionally assume a hinge function.
- a handle opening 26 is attached to the elastic element 20 opposite side of the access door 14.
- the access door 14 may also have a recessed grip or a retaining loop on its top and / or bottom.
- FIG. 2 shows the access flooring 10 in a plan view from above.
- the elongate profile 22 in the region 18 is arranged so that the access door 14 can be opened transversely to the longitudinal side of the access flooring 10.
- the flexible connection through the elongated profile 22 can also be done on one of the other sides of the access door 14 (and this in any embodiment), so that it can be opened, for example, in the longitudinal direction to the access flooring 10.
- the access flooring 10 is shown with closed access door 14.
- the access door 14 is held securely by the access deck 10. Occurring weight forces of the closed access door 14 and possibly on her objects or persons are derived by the edge formation as evenly as possible on the access flooring 10.
- FIG. 3 shows a cross section of FIG. 2 along the in FIG. 2 drawn sectional plane III-III at the closed access opening 12.
- the access door 14 is flexibly connected by the elastic member 20 with the access deck 10.
- the elastically deformable element 20 is designed as an elongated profile 22 with a rectangular cross-section.
- the access floor 10 has a second groove 30 which, when the access door 14 is closed, faces the first groove 28 and into which the elongate profile 22 engages with a second partial area.
- the elongate profile 22 is fastened both in the first groove 28 and in the second groove 30 by a surface bonding.
- FIG. 3 clearly shows that the access door 14 is inserted into the formation 32 of the edge 16 of the access opening 12 and that both the upper edge of the access door 14 and the upper edge of the access floor 10 are at the same height.
- the access flooring 10 according to the invention is shown in FIG. 3 simplified and not drawn to scale. In particular, the between the access door 14 and access deck 10 respectively right and left in FIG. 3 columns, which ensure a smooth opening and closing of the access door 14, in reality a much smaller gap on.
- the access flooring 10 may additionally comprise a conductor (not shown) which is releasably and / or pivotally mounted during transport and storage of the access flooring 10 below the access door 14 and the bottom of the access decking 10. After installation of the access decking 10 in a scaffold, the ladder can be folded from the access decking 10 to reach the access decking 10 of an underlying pavement.
- a conductor not shown
- FIG. 4 corresponds to that shown in FIG. 3, however, the access door 14 is opened and the access opening 12 can be passed by a person, for example a construction worker. Since the elongate profile 22 is fixed both in the first groove 28 of the access door 14 and in the second groove 30 of the access deck 10, occurs when unfolding the access door 14, a material deformation in a portion 34 of the elongate profile 22. The material deformation may be present in some subregions of the elongated profile 22 as positive elongation (elongation) and in other subregions as negative elongation (compression). In FIG. 4 is formed in the region 34 on the underside of the elongated profile 22 an extension and on the top of a compression.
- the elastically deformable element 20 is designed such that the force generated by the deformation of the elastically deformable element 20, which is opposite to the opening movement of the access door 14, abruptly increases from an opening angle ⁇ near a vertical position of the access door 14.
- the opening angle ⁇ is presently about 85 °, but may also be greater or less than 85 °.
- FIG. 5 is the cross-section of a partially V-shaped elongated profile 40 which is held in a first groove 42 of a pass-through flap 44 and a second groove 46 of a pass-through pad 48.
- the edge area of the Passage door 44 rests on the access floor 48, provided that the access door 44 is closed.
- the elongated profile 40 is deformed and tries, due to its elasticity, to assume its original shape again. This creates a restoring force, which closes the access door 44, unless it is held in its open position by using a holding force.
- the restoring force has a different dependence on the opening angle of the access door 44, as would be the case with an elongate profile of rectangular cross-section, in that the opening angle ⁇ of the access door close to its vertical position, from which the restoring force of the elastically deformable element with increasing opening of the access door 44 increases abruptly, is defined again more precise.
- the two legs of the V-shaped part of the profile 40 initially move toward each other. Since the profile 40 in the region of the V-shaped legs has a significantly smaller thickness than in the horizontally extending region, only a small force is initially required for this.
- the two legs abut each other and it must be a significantly greater force expended to deform the horizontally extending portions of the profile 40 and so the access door 44 even further open (larger opening angle).
- the access door 44 can thus be opened by low force only up to a certain angle ⁇ . If this angle is exceeded, the force required for further opening increases sharply (eg disproportionately or exponentially).
- the elongated profile 50 in FIG. 6 has, instead of a V-shaped, a substantially W-shaped cross-section and is held in a first groove 52 of a pass-through flap 54 and a second groove 56 of a pass-through covering 58.
- the opening angle a from which the force required increases sharply, is in a range near 90 degrees.
- FIG. Fig. 7 shows a first possibility of fixing the elastic element in cross-section.
- the elastically deformable element is designed in the form of an elongate profile 80.
- the profile 80 engages with a first portion in a first groove 82 of an access decking 84 and is held in the groove 82 by retractable screws 86 on the access deck 84.
- a second portion of the elongate profile 80, which lies opposite the first portion, has a T-shaped cross section, which serves as an undercut 88, and engages in the transverse direction of the elongate profile 80 in a form-fitting manner in a correspondingly shaped groove 90 of the access door 92.
- the profile 80 can additionally be secured in the groove 90 by adhesive bonding.
- FIG. 8 a permanent attachment of an elongated profile 94 with a access deck 100 and an access door 98 through rivets 96 is shown in cross-section.
- the elongate profile can also assume the hinge function, as in other embodiments shown.
- To define the profile 94 engages with a first portion in a first groove 102 of the access door 98 and with a second portion in a second groove 104 of the access floor 100 a.
- the profile 94 is provided both in the first and in the second portion with openings, such as holes or circular punched.
- the access decking 100 and the access door 98 have holes that are aligned with the corresponding openings 94 of the profile.
- first groove 102 first portion is now held by rivets 96, which extend through the holes of the access door 98 and the openings in the first portion of the profile at the access door 98. In a similar way is held the second portion of the profile 94 on the access deck 100.
- rivets 96 In addition to solid rivets, hollow or blind rivets are also suitable for attachment.
- FIG. 9 One way to connect a access deck 106 with a access door 108 through an elongate profile 110 of rectangular cross-section is shown in FIG. 9 shown.
- Both the edge of the access flooring 106 along the access opening and the edge of the access door 108 have on their upper side recesses 112, 114 each having a rectangular cross section.
- the elongated profile 110 is inserted in each case with a portion. The depth of the recesses is selected such that the upper edge of the profile 110 is flush with the upper edge of the access door 108 and the upper edge of the access floor 106 or the upper edge of the profile 110 compared to the upper edge of the access door 108 and the upper edge of the access deck 106 deeper lies.
- the elongate profile 110 is fixedly connected by screw connections 116, each with a partial area, to the access flooring 106 and the access door 108.
- screw connections 116 each with a partial area
- screws are used with normal or self-tapping thread. Due to the arrangement of the elongated profile 110, the gap 118 existing between the access floor 106 and the access door 108 is completely covered. Ingress of dirt or small parts in the gap is reliably prevented. Likewise, it is prevented that a person accidentally injured by pinching in the gap 118 when opening the access door 108.
- FIG. 10 shows an access flooring 120 according to the invention in a cross-sectional view.
- a hinge 126 recessed on the top of the access flooring 120 and the access door 122 is used.
- the elongated profile 124 is held by means of two undercuts 128 both in a first groove 130 of the access flooring 120 and in a second groove 132 of the access door 122.
- Both the arrangement of the hinge 126 and the shape of the illustrated cross section 134 of the access floor 120 and the matching shape of the illustrated cross section 136 of the access door 122 reliably prevent dirt from entering the area 138 in which the elongated profile 124 is located. Likewise, accidental jamming when opening the access door 122 is prevented.
- an elongate profile 140 can be used to influence the restoring force; 148, which with an access door 142; 150 and an access deck 144; 152 is flexibly connected and a plurality of cavities 146; 154 has been used.
- the cavities 146; 154 preferably arranged in a region in which when opening the access door 142; 150 a material deformation occurs.
- the cavities 146 are formed as open V-shaped notches on the top of the elongated profile 140. The notches extend on the top approximately in the center of the longitudinal direction of the profile 140 and ensure that when opening the access door 142, the area in which otherwise the largest material extension of the profile 140 would occur relieved.
- the access door 142 can therefore be opened with less effort and it is an early material fatigue prevented by overstretching of the elongated profile 140.
- an elongate profile 148 may be traversed by cavities 154 which extend completely in the direction of the longitudinal sides of the profile 148 in its interior.
- the cavities 154 have a circular cross-section and are arranged in a region of the profile 148 which is compressed when the access door 150 is opened. As a result, in the area of small opening angle of the Passage door 150 reduces the resulting restoring force.
- these cavities may also have other cross-sectional shapes, such as triangular.
- a flexible cover 164 may be disposed above the elongated profile 156 to protect an elongated profile 156 which is connected to a walk-through door 162 and a walk-up decking 160.
- the flexible cover 164 is attached to both the access floor 160 and the access door 162 and thus also protects the connection area 158, which is located between the access floor 160 and the access door 162.
- the flexible cover 164 is ideally dust- and liquid-tight and consists of a very elastic, tough and environmentally insensitive material, such as a plastic film. Dust, for example, caused by grinding on a facade, thus can not enforce the connection portion 158 and thereby affect the function of the elongated profile 156.
- the attachment of the cover 164 can advantageously be done with the same connecting elements, which also connect the elongated profile 156 with the access decking 160 and the access door 162.
- screws 166 penetrating both the flexible cover 164 and the elongate profile 156 have been used.
- FIG. 14 shows that when the access door 162 is opened, the flexible cover 164 is compressed. If a material with very high flexibility is used for the flexible cover 164, then this affects the restoring force generated by the elongated profile 156 only insignificantly.
- the cover 164 can also be designed so that the restoring force generated by the elongated profile 156 cooperates with a restoring force generated by the cover 164.
- the cover 164 acts an undesirable penetration of dirt, such as stones or Material chips, in the formed between the access door 162 and the access decking 160 gap.
- FIG. 15 shows the cross-sectional representation of a region in which a pass-through flap 172 is connected to a access decking 174.
- the connection between the access door 172 and the access floor 174 is made by a in the access door 172 as well as the access floor 174 embedded stable band 168, which is fastened by rivets 170.
- the band may consist of a textile, of an elastomer or of another suitable material.
- a first elastically deformable element 176 is arranged above the fabric strip 168 and a second elastically deformable element 178 is arranged below the fabric strip 168.
- the first elastically deformable element 176 fills only a part of the gap region and consists of a tough and less elastic material.
- the second elastically deformable member 178 is made of a strong elastic and soft material.
- the second elastically deformable element 178 is already compressed with the access door 172 closed, that is, it is compressed in the gap. Due to its compression, the second elastically deformable element 178 exerts a force on the access door 172, which acts in the direction of an opening movement and thus reduces the effort required to open the access door 172.
- the first elastically deformable element 176 is compressed in the gap only at the above-described opening angle ⁇ (not shown) near the almost vertically opened access door 172.
- the two elastically deformable elements 176, 178 counteract penetration of contaminants, such as stones or chips of material, into the gap formed between the access door 172 and the access floor 174.

Abstract
L'invention concerne un plateau- trappe d'accès pour échafaudage comportant un volet de trappe d'accès qui ferme une ouverture passage ménagée dans le plateau-trappe d'accès et est fixé à celui-ci de manière à pouvoir être rabattu. 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.
