Description

According to the invention, a first aspect of the present disclosure relates to a module for realising a construction for supporting a detached scaffold by coupling at least three of said modules with each other.
According to a second aspect, the present disclosure relates to a construction for supporting a detached scaffold by coupling at least three modules according to the first aspect of the present disclosure.
According to a third aspect, the present disclosure relates to a detached scaffold or decor wall supported by a construction according to the second aspect.
According to a fourth aspect, the present disclosure relates to a decor wall comprising a detached scaffold according to the third aspect of the present disclosure.
Scaffolds known in the art are used for a wide range of applications such as placement along the outside walls of a building, to serve as a support platform on which construction workers carry out work on said building wherein the scaffold is shielded from wind by the building or attached to the building for providing stability to the scaffold. Another common application of scaffolding is for providing a decor wall such as used during outdoor concerts wherein the scaffold is detached or freestanding, i.e. not attached or shielded by a building. A desired stability and strength of the detached scaffold to withstand external forces acting on the detached scaffold is achieved by extending the scaffold in a cube like manner using known scaffolding material. Realising a detached scaffold in this way is however relative time and space consuming. FR 91474 discloses a foldable and dismountable scaffold.
An objective of the present disclosure is therefore to provide a module for supporting a detached scaffold for realising a construction having a desired stability in a relative short time.
This objective is realised in that module according to the present invention comprises a first element, a second element and a third element,

wherein said first element is pivotably connected, by a first pivotable connection, to said second element,
wherein said third element is pivotably connected, by a second pivotable connection, to one of said first element and said second element, and wherein said third element is releasably connectable to the other of said first element and said second element,
wherein said third element, when connected to the other of said first element and said second element, is arranged for transferring a force acting on said first element to said second element,
wherein said first element and said second element are provided each with a coupling arrangement for coupling said at least three modules next to each other and above each other for providing said construction. The module according to the first aspect of the present disclosure is arranged for realising a construction for supporting a detached scaffold by coupling at least three of said modules with each other. After connection of said third element to the other of said first element and said second element, the module forms a substantially triangular shape. By placing at least two of these triangular shaped modules next to each other and a third of the triangular shaped modules on top of the first two triangular shaped module a general triangular construction for supporting the freestanding scaffold is obtained in a relative short time period for supporting a detached scaffold such as a decor wall.

The present invention at least partly relies on the insight that producing a support construction for a detached scaffold is relative time consuming when using standard scaffolding material. Moreover, for realising a desired support functionality a relative large construction needs to be realised making the construction relative expensive due to required manual labour and material.
Within the context of the present disclosure a detached scaffold is to be understood as a scaffold that is free standing and as such for instance not attached to a wall of a building. Such free standing scaffolds are for instance applied for realising a free standing construction such as used during a concert, opera or presentation.
Preferably, the first element has a length in the range of 7.5 - 8.5 meters and the second element has a length in the range of 3.0 - 4.5 meters. These dimensions allow the modules to be transported by regular transport means such as a trailer coupled to a truck. Moreover these dimensions allow to realize a relative large construction for supporting a detached scaffold using a relative small number of modules according to the first aspect of the present disclosure while allowing said modules to be transported using regular transportation means such as trucks and trailers without the need for special transport.
Preferably, said module has a width perpendicular to said length of said first element and said length of said second element wherein said width of said module is in the range of 2 - 2.5 meters. A width in this range allows the modules to be transported by regular transport means such as on a trailer coupled to a truck.
In an embodiment of the module said first element and said second element are provided each with a coupling arrangement for coupling said at least three modules next to each other and above each other for providing said construction.
It is advantageous if said first pivotable connection of said first element to said second element is realised by a connection of said coupling arrangement of said first element to said coupling arrangement of said second element. This is advantageous to realise a module having a relative small number of elements for realising a module having a relative low complexity and that can be produced at relative low cost.
In this regard it is beneficial if said first element and said second element are arranged to extend in a substantially same direction, preferably in a flat virtual plane, when said third element is released from connection from said other of said first element and said second element. The module in the folded configuration can be easily transported to and from the location of construction and comfortably handled in the process of building the construction, due to its reduced volume.
Preferably, said coupling arrangement of said first element comprises a first coupling body, located at a first end of said first element, and a second coupling body, located at a second end of said first element, wherein said second end is opposite said first end of said first element, wherein said first coupling body of a module of said at least three modules is arranged for coupling with said second coupling body of a further module of said at least three modules. This is beneficial for allowing connection of modules in a relative short time period. Moreover said modules have a relative small number of elements for realising a module having a relative low complexity and that can be produced at relative low cost.
In this regard it is beneficial if said coupling arrangement of said second element comprises a third coupling body, located at a first end of said second element, and a fourth coupling body, located at a second end of said second element, wherein said second end is opposite said first end of said second element, wherein said third coupling body of a module of said at least three modules is arranged for coupling with said first coupling body of a further module and/or a second coupling body of a further module of said at least three modules and wherein said fourth coupling body of a module of said at least three modules is arranged for coupling with said first coupling body of a further module and/or a second coupling body of a further module of said at least three modules. This is beneficial for allowing connection of modules in a relative short time period. Moreover said modules have a relative small number of elements for realising a module having a relative low complexity and that can be produced at relative low cost.
In an embodiment of the module according to the first aspect said first coupling body and said second coupling body and/or said third coupling body and said fourth coupling body are provided each with parallel wall elements, wherein said parallel wall elements of said first coupling body are arranged to receive in a receiving space between said parallel wall elements of said first coupling body parallel wall elements of said second coupling body and/or parallel wall elements of said third coupling body and/or parallel wall elements of said fourth coupling body. The provision of parallel wall elements is beneficial for realising a desired alignment of the modules for realising said construction in a relative short time period.
In this regard it is advantageous if in said receiving space of said second coupling body a coupling element is provided that is arranged for being received in said receiving space of said first coupling body of a further module. Preferably, said coupling arrangement of said first element comprises said coupling element.
It is advantageous if said coupling arrangements are provided with holes for receiving coupling organs for coupling said at least three modules. This is beneficial for coupling modules for realising said construction in a relative short time period.

Preferably, the longitudinal profiles are metal profiles, preferably comprising steel, preferably hollow or channel shaped metal profiles. In a relative light weight embodiment of the module according to the first aspect, the longitudinal profiles are made from hollow aluminium profiles.
In this regard, it is beneficial if said third element is provided with a translation organ, wherein said translation organ is translatable over a surface in said longitudinal direction of said other of said first element and said second element when said third element is released from said other of said first element and said second element.

Preferably, said translation organ comprises a roller that is rollable over an outer surface in said longitudinal direction of said other of said first element and said second element when said third element is released from connection from said other of said first element and said second element. Advantage of this is that the longitudinal elements are not damaged in process of detaching and attaching the third element and the subsequent folding of the module. Furthermore the roller can support part of the weight of the assembly, therefore diminishing the load that needs to be lifted for bringing the element from a folded into the triangular position..

The cross-members 61 and 63 are welded to the longitudinal profiles and provide the first element 7 and the third element 11 with a relative large stability. One of the longitudinal profiles 37 of the first element 7 is provided with brackets 59. The brackets 59 are distributed at substantially equal mutual distance along the length of the first element 7 and are arranged for guiding cables, wiring and function as a climbing arrangement for workers to climb along the first element in a vertical direction when the first element 7 of the module 1a, 1b, 1c is in use vertically oriented.
The profiles 39 of the second element 9 are mutually connected via a support structure for supporting a worker when second element 9 of the module 1a, 1b, 1c is in use horizontally oriented.
