Definitions

  • the invention relates to a scaffolding floor with connecting elements arranged at its ends for connection to a quick scaffolding, consisting of a one-part or multi-part hollow box profile made of metal, which extends over the length of the scaffolding floor and is provided on the end face with end elements which are made entirely or partially of elastically flexible Made of rubber or plastic and each have an outer section protruding from the end of the box section and at least one fastening section projecting into the cavity of the box section.
  • the invention proposes starting from the scaffolding floor of the type mentioned that the end elements are provided with vertical openings to the level of the scaffolding floor receiving openings for retaining pins located on the scaffold and that the fastening sections of the end element with the box girder profile perpendicular to the level of the scaffolding floor running, pressed-in rivets are connected, which are surrounded in the fastening area of the fastening section by elastic plastic or rubber, the clear width of the box section, the thickness of the fastening section and the length of the pressed-in rivets are matched to one another such that the elastically flexible rubber or plastic of the Fastening section in the vicinity of the rivets is due to deformation of the wall of the hollow box profile under strong elastic compressive stress.
  • This type of attachment requires only a single pressing process for the insertion of the rivets and the slight deformation of the walls of the hollow box profile for the connection between the hollow box profile and the closure element and results in a particularly intimate and looseness-free bond between the closure element and the hollow box profile.
  • the force transmission between the hollow box section and the end element takes place in a particularly advantageous manner over a large area in the area surrounding the rivets and not only in the area of the perforation of the bores in the box section receiving the rivets.
  • the arrangement of the receiving openings in the end elements has the advantage that, when the scaffolding floor is inserted into the scaffolding floor, the holding forces are distributed over a large area to the hollow box profile without additional rails or the like being required in the end regions of the scaffolding floor.
  • a first embodiment provides that the receiving openings for receiving the retaining pins of the scaffold are arranged in the fastening area of the closing element and penetrate both the fastening section of the closing element and the end section of the hollow box profile.
  • This arrangement of the receiving openings has the advantage that when the scaffolding floor is inserted into the scaffolding, the holding forces act directly in the area of the hollow box section reinforced by the fastening section of the closure element.
  • a second embodiment provides that the receiving openings for receiving the holding pins of the scaffold are arranged in the transition area between the outer section and the fastening section of the closure element and penetrate the end edge areas of the hollow box profile.
  • the holding forces are introduced approximately in the middle of the closure element, so that there is a particularly uniform distribution of the holding forces over the cross section of the hollow box profile.
  • a third embodiment provides that the receiving openings for the holding pins of the frame are arranged in the outer section of the closure element. In this embodiment, there can no longer be permanent deformation of the walls of the hollow box section in the attachment area of the holding pins of the scaffold. In addition, the holding forces are largely damped and evenly introduced into the hollow box profile.
  • the receiving openings for the holding pins are expediently formed by hollow rivets which are open on both sides or provided with a metallic lining.
  • the hollow rivets here have the advantage that they are additionally supported and held by the rubber or plastic mass under high compressive stress, so that the holes in the hole in the Hollow box profile forces are smaller and it is not so easy to permanent deformation of the wall of the hollow box profile. There is a risk of such deformations if the scaffold floor is accidentally on one side only the holding pins of the scaffold are put on and loaded at the other end.
  • the receiving openings for the holding pins of the scaffold are arranged in the outer section of the end element projecting above the hollow box profile, it is sufficient to provide the receiving openings with the above-mentioned metallic lining, which prevents tearing of the rubber or plastic.
  • the outer corners of the end elements are also expediently rounded. This makes it possible to insert the scaffold floors in the scaffold with different frame widths, if necessary. In addition, the rounding-off reduces the risk of injury when setting up, dismantling or transporting the scaffolding.
  • FIGS. 1a to c the multi-part hollow box profile made of aluminum, which forms the surface area of the scaffolding floor, is designated by the reference number 1.
  • This box girder section 1 is connected at both ends (only one of the ends is shown in the drawing) to a closure element 2 made entirely of rubber-elastic material.
  • This closure element expediently consists of vulcanized natural or synthetic rubber with a Shore A hardness of 80 to 85 ° .
  • the closure element 2 has a fastening section 3 projecting into the interior of the hollow box section 1 and an outer section 4 projecting beyond the end section of the box section.
  • the outer section 4 is aligned with the outer surfaces of the hollow box section 1 and is rounded at the corners with a large radius, so that the scaffold floor can be inserted into vertical frames of different sizes of the scaffold.
  • the fastening section 3 has three projections 3a, 3b and 3c, one of which projects into a channel 1a, 1 and 1 of the hollow box section 1. This makes it possible to leave the webs between the channels 1 a, 1 b and 1 c almost up to the front end of the hollow box section (see FIG. 1 b). Since in the embodiment of FIGS. 1a to c the hollow box section 1 extends into the area of the rounded corners of the end element 2, the corners of the box section 1 are correspondingly rounded here, so that the outer section 4 also has approximately the same width in the area of the corners as at the front of the scaffold floor.
  • the end section of the hollow box section 1 is first prepared by rounding off the corners and separating the webs between the channels 1a, 1 and 1, as can be seen from FIG. 1. Then the closing element 2 with its fastening section 3 is inserted into the end of the hollow box section 1 such that the holes in the hollow box section 1 and fastening section 3 are aligned. Then the rivets are in these holes. 5a and 5b introduced and pressed by means of a rivet press.
  • the lengths of the rivets 5a and 5b, the thickness of the fastening section 3 and the inside width of the hollow box section 1 are coordinated with one another in such a way that when the rivets 5a and 5b are pressed in, the upper and lower walls of the hollow box section 1 are deformed inwards such that the rubber-elastic material of the fastening section 3 in the vicinity of the rivets 5a and 5b is placed over a large area under a strong elastic compressive stress. This results in a good hold and an intimate bond between the hollow box section 1 and the fastening section 3 of the end element 2.
  • the two outer rivets 5a are formed in the embodiment of Figures la to c as hollow rivets open on both sides.
  • the openings of these hollow rivets 5a also serve as receiving openings 6 for receiving the holding pins of the frame, which are not shown in the drawing.
  • FIGS. 1 a to c The embodiment of Figures 2a to c largely corresponds to the embodiment of Figures 1a to c, so that the same reference numerals can be used for the corresponding parts.
  • Ben section 4 of the end element 2 is wider so that rounding of the corners of the hollow box section 1 can be omitted.
  • the projections 3a, 3b and 3c of the fastening section 3 begin here in the region of the interface between the fastening section 3 and the outer section 4. For this reason, the webs between the channels 1a, 1b and 1c of the hollow box section 1 can reach up to that Stop the end of the box girder section 1.
  • the holster profile requires less processing than in the embodiment according to FIGS. 1 a to c.
  • the hollow rivets 5a forming the receiving openings 6 for the fastening pins of the framework are arranged in the transition region between the outer section 4 and the fastening section 3 of the closure element 2. Accordingly, the end section of the hollow box section 1 in this exemplary embodiment is not only provided with holes for receiving the rivets 5b, but also with semicircular recesses on the end face for receiving the hollow rivets 5a.
  • FIGS. 3a to 3c largely corresponds to the exemplary embodiment in FIGS. 2a to c.
  • metallic linings 7 are also provided in the receiving openings for the holding pins of the framework, which prevent the rubber-elastic material from tearing.
  • the processing effort at the end section of the hollow box section 1 is lowest in the last-mentioned exemplary embodiment.
