Abstract

A scaffold platform section is fashioned as a corner platform section (117) and exhibits an optionally multipartite floor plate (27) at which at least one supporting leg (29) is bent at an angle, carrying drop-in claws (13) or the like. A supporting leg has a lower lift-preventing leg (30) extending to below the U supporting span member (14) in the drop-in position. This platform section bridges a great variety of different angular regions between other scaffold platforms and can have a swivel member (37) for compensating purposes. The corner platform section (117) proper can be equipped with a border leg (35). The swivel member (37) can have a border leg (38). Two component elements can be joined in a swivelable and inflexible fashion.

Claims

1. A scaffolding arrangement for enabling a set-up of scaffolding in and around irregular shaped objects with non-parallel boundaries, the scaffolding arrangement including at least one scaffolding platform section extending in a first direction, at least one further scaffolding section extending in a second direction inclined with respect to the first direction such that a corner gap is formed between adjacent ends of the scaffolding platform sections, a corner platform means for bridging the corner gap including a floor plate means for defining a walking for working surface having drop-in means provided along at least one edge thereof for securing the floor plate means to a support means, with another edge thereof being adapted to being supported by resting on one of the scaffolding platform sections, and wherein an outer peripheral edge of the floor plate means extending between the edge provided with the drop-in means and the edge supported by resting on one of the scaffolding platform sections is one of linear, bent, or rounded in dependence upon a position of the adjoining scaffolding platform sections and support means thereof whereby the floor plate means maximally covers a corner angle defined by said corner gap.

2. A scaffolding arrangement according to claim 1, wherein the drop-in means includes claws fastened on and outside of a supporting leg means of said floor plate means, and said supporting leg means being substantially perpendicularly bent with respect to a plane of said floor plate means and including lift-preventing leg means at a lower end thereof bent outwardly into a horizontal plane and lying below a horizontally extending supporting span member of the support means.

3. A scaffolding arrangement according to one of claims 1 or 2, wherein the support means includes support posts joined to said scaffolding sections by transverse connection means, and wherein the corner platform means extends above the transverse connection means and includes at the edge adapted to be supported in the scaffolding platform sections marginal leg means bent away in a downward direction by a thickness of the transverse connection means.

4. A scaffolding arrangement according to one of claims 1 or 2, wherein the corner platform means further includes a pivotable member articulated so as to be pivotable beneath the floor plate means, and wherein a widest portion of said pivotable member is shaped correspondingly for pivoting over the corner gap.

5. A scaffolding arrangement according to one of claims 1 or 2, wherein the corner platform section includes an upwardly projecting border leg means along the outer peripheral edge of the floor plate means.

6. A scaffolding arrangement according to claim 4, wherein the pivotable member includes border leg means disposed along an outer peripheral edge thereof.

7. A scaffolding arrangement according to claim 6, wherein the outer peripheral edge of the floor plate means extends up to a corner point defining a central pivoting position of the floor plate means and the pivotable member with respect to each other, of about 45°

, said floor plate means including a linear section extending from the corner point to the edge adapted to be supported by resting on one of the scaffolding platform sections in such a manner that the floor plate means leaves, in a 90°

pivot position between the linear section and an outwardly located support post of the support means, a small vacant space for accommodating the border leg means of the pivotable member.

13. A scaffolding arrangement according to one of claims 1, 2, 8, or 9, wherein said drop-in means includes engaging means for enabling a safe connection with the support means.

14. A scaffolding arrangement according to claim 13, wherein the engaging means includes drop-in eye means for attachment of retaining pin means freely movable in an upward direction.

15. A scaffolding arrangement according to claim 14, wherein the drop-in eye means are attached to a downwardly angled vertical supporting leg means of the floor plate means.

16. A scaffolding arrangement according to claim 13, wherein the engaging means include at least one of beads, prisms, double claws, double hooks, double beads, or double prisms.

17. A scaffolding arrangement according to claim 13, wherein a space is provided between an upper portion of the engaging means and a transverse connecting means of the support means, said space is less than a height of an overlap of the engaging means on the support means.

8. A scaffolding arrangement for enabling a set-up of scaffolding in and around irregular shaped objects with non-parallel boundaries, the scaffolding arrangement including at least one scaffolding platform section extending in a first direction, at least one further scaffolding section extending in a second direction inclined with respect to the first direction such that a corner gap is formed between adjacent ends of the scaffolding platform sections, a corner platform means for bridging the corner gap including two floor plate means for defining a walking or working surface each including drop-in means provided along at least one edge thereof for securing the respective floor plate means to a support means, said two floor plate means being disposed in a partially superimposed relationship and being joined so as to be mutually pivotable about a center point lying in a predetermined position in dependence upon a position of the adjoining scaffolding sections.

9. A scaffolding arrangement according to claim 8, wherein an outer peripheral edge of each of said two floor plate means is configured in the shape of a divided circle.

10. A scaffolding arrangement according to one of claims 8 or 9, wherein the outer peripheral edges of the respective floor plate means includes at least one mutually insertable guiding border leg means or at least one divided circle-slotted hole means for forming a sliding connection between said two floor plate means.

11. A scaffolding arrangement according to claim 10, wherein at least one guiding border leg means is formed with a shaped point-contact protuberance means on a portion of one of the floor plate means.

12. A scaffolding arrangement according to claim 10, wherein only one drop-in means includes a lift-preventing leg means for preventing a lifting of the floor plate means from the support means.
