TECHNICAL FIELD
[0001] The present disclosure relates to the fields of scaffolding and elevated working. he present disclosure relates in particular to the field of protecting a worker's workspace on the scaffolding.
BACKGROUND
[0002] It is well known that working on a structure such as a building such as a house may require use of a scaffold to provide worker's workspaces in elevated positions about at least part of the building. A typical example of a scaffold is a movable scaffold that may be moved by rolling on wheels from one working position to a next working position on the building.
[0003] Scaffolds are structures made of scaffolding, a temporary modular system of tubes and/or beams forming a framework used to support workers and material in construction, maintenance, and/or repair, etc., of buildings and other large structures. Scaffolding modules may comprise flooring members supported on uprights such as ladder-like modules and/or stackable posts provided with connectors. The scaffolding may also comprise horizontal and/or diagonal trusses between uprights. Erected scaffolds are usually anchored with anchors to the building or structure under construction, maintenance, and/or repaired, etc. by workers.
[0004] Workers' working conditions are very important for workers' safety and wellbeing and they a constant concern in the field. Also, for particular types of work such as bricklaying and/or painting operations, environmental conditions may be decisive for an outcome of the operation. E.g. working conditions may be hazardous (heat, sun, storm, hail, snow, sleet, etc.), and/or (application of) fresh paint may be affected and damaged by one or more of rain, hail, snow, sleet, dust, animals (e.g. insects, birds / bird droppings, etc.), etc.
[0005] In view of such concerns, it is well known to attach a cover for at least part of the workspace to the scaffold. Such covers generally are of a wind-breaking and/or at least partly watertight or water-repellent fabric, such as nets, sails, tarpaulins, etc.
[0006] However, a cover may hinder access to the work space, e.g. for transporting tools and/or supplies, so that it should be removable. Also, e.g. in view of wind strengths a cover on a scaffolding may be have to be removed for protection of one or more of the construction, the scaffolding, the cover, and/or for prevention of noise due to flapping material.
[0007] Attachment, removal and storage of such covers are cumbersome and cost significant amounts of time and effort. The covers tend to be fragile, compared to other scaffolding elements.
SUMMARY
[0009] In view of the above, herewith is provided a scaffolding assembly comprising scaffolding for erecting a scaffold, for operable positioning at and/or against a portion of a construction and providing a work space for a worker, in particular an elevated work space, and a cover for covering at least part of the work space. The assembly further comprises a roller device for reversibly (un-)rolling a rollable portion of the cover to (from) a rolled-up configuration from (to) an unrolled configuration for (un-)covering the at least part of the work space.
[0010] Thus, the cover may be applied and/or removed easily compared to folding the cover. The rolled cover may be stored as a roll. The rolled cover may be stored on and/or in the roller device. The cover may be rollable as a whole.
[0011] The (un-)rolling may relate to only part of a complete rollable portion of the cover. The rolled-up configuration and/or the unrolled configuration may be with respect to each other. In the rolled-up configuration and/or the unrolled configuration a first part of the rollable portion of the cover may be unrolled or rolled up, respectively, while a second part of the rollable portion remains unrolled or rolled up, respectively.
[0012] The cover may protect the work space against external influences such as weather influences, like one or more of sun, wind, precipitation, dust, leaves, debris, bird droppings, etc. Also or alternatively, the cover may protect an environment from (effects of) work performed in the work space, e.g. in case of welding, grinding, drilling, etc. the cover may protect an environment against dust, debris, sparks, hot material, bright light, etc. which are created in the work space, and which may possibly be (sent) flying from the work space.
[0013] At least part of the rollable portion of the cover may be formed as a sheet or web of scaffold cover material. At least part of the rollable portion of the cover may be formed as one or more of a scaffolding fabric, a windbreaking fabric, a weather protection fabric, a tarpaulin, a fire retardant fabric, a welding fabric. Suitable scaffold cover materials for covering scaffolds are known; the material preferably is a mesh or an open pore fabric like a net and has about 5% or more open fraction, e.g. about 10% or more open fraction such as 15% to 20% open fraction so as to reduce but not to stop wind. One or more parts of the cover may be opaque.
[0014] The construction may be any construction (to be) worked on by the worker, e.g. a building, a technical installation, etc. The portion of a construction may be a wall of a building, such as a house or the like. In some cases, the scaffolding may surround the work space and/or the construction may be at least in part formed by further scaffolding.
[0016] The roller device may be mounted or mountable to the scaffolding for, at least when mounted, reversibly (un-)rolling the rollable portion to (from) the rolled-up configuration from (to) the unrolled configuration.
[0017] Thus the roller device may remain at hand for applying and/or removing the cover. Also or alternatively, a portion of the cover may remain rolled up while an unrolled portion of the cover is used for covering the at least part of the work space.
[0018] The roller device may be configured for reversibly (un-)rolling the rollable portion onto and from a core, respectively, for the rolled-up configuration and the unrolled configuration.
[0019] This may facilitate rolling up the cover; the cover may be attached to the core; attachment of the cover to the core in plural places or along a length of the core may prevent application of local forces onto the cover for rolling the cover; this may prevent damage. A core may help rolling the cover straight, e.g. preventing sideways deviation, folds and/or local build-up of material on the roll. A core may provide fortification to the roll.
[0020] The roller device may comprise a rotatable core and may be configured for (un-)rolling the rollable portion onto (from) the core.
[0021] The core and/or cover may be an integral part of the rolling device or be a separate part so that the rolling device may be used with plural cores and/or covers.
[0022] The core may be a rotatable axle and/or may be a hollow core rotatably mounted about an axle, and/or wherein the core comprises flanges for guiding rolling-up of cover material
[0023] A hollow core, e.g. a tubular body, reduces weight. A hollow axle may facilitate rotation. A hollow core rotatably mounted about an axle may facilitate exchanges of cores and/or rolls of cover on a core. A tubular core may be open on one or both axial ends, with may correspond to a main longitudinal direction of the core. A hollow core, in particular if one or both axially opposite ends of the core are open, may also facilitate transport and/or storage of the core and/or of a roll on such core by insertion of a tool and/or support into the core.
[0024] Note that herein references such as "axial direction" and the like refer to a rolling axis unless otherwise specified.
[0025] The roller device may comprise a housing at least partly enclosing at least part of the rollable portion in the rolled-up configuration.
[0026] The roller device may comprise a housing at least partly enclosing at least part of the rollable portion in the rolled-up configuration. Thus, the rolled-up portion may be protected from external influences.
[0027] The housing may enclose the core and any cover material rolled onto the core. The housing may form an open sleeve surrounding the core and any rolled-up cover part substantially fully, but leaving an opening for passing unwound cover material onto and/or from roll. E.g. the housing may be configured surround the core and/or the roll for more than 270 degrees about the axis, preferably more than 300 degrees more preferably more than 330 degrees e.g. leaving open less than 30 degrees, preferably less than 20 degrees such as about 10 degrees or 5 degrees or less.
[0028] The housing may preferably strong enough to support a worker, possibly adhering to one or more of dimensions, sizes and/or strengths according to one or more (safety) standards.
[0029] The housing may be openable, in axial direction and/or, preferably in a tangential direction e.g. being a multipart housing wherein different parts are hinged together; such latter construction may facilitate access to the rolled-up (portion of the) cover, a core and/or any other structures within the housing.
[0030] The roller device may be configured to urge the rollable portion into an at least partly rolled-up configuration.
[0031] This may facilitate removing the cover and rolling it up. Also, or alternatively it may help arranging the cover on the scaffold and/or tightening the cover to the scaffold.
[0032] The roller device may be provided with at least one resilient element for urging a core and an axle and/or housing to one or more particular relative positions.
[0033] The roller device may comprise one or more of a human-powered drive and a power drive for effecting the (un-)rolling, in particular for driving a core.
[0034] A human-powered drive may comprise a handle, a belt drive, a chain drive, etc. The roller may be formed as a winch. Also or alternatively, a power drive may be provided by a drive comprised in the roller device such as an electromotor, or an external drive such as a power tool, e.g. a powered drill or screwdriver.
[0035] The roller device may comprise a brake and/or stop for determining an amount of (un-)rolled cover, e.g. for determining a position of a core and/or an axle relative to a mounting and/or housing of the roller device.
[0036] This may increase safety and/or may facilitate applying and/or fixing the cover onto the scaffold.
[0037] The roller device may comprise a mounting for operably mounting to the scaffolding and a scaffold cover material on a core rotatable with respect to the mounting.
[0038] Thus, the roller device can be readily included in a scaffold. It is noted that most scaffolding is modular and adheres to standard sizes; the mounting may adhere to the modular system and the roller device be a scaffolding module.
[0039] The assembly may comprise one or more fasteners for fastening an unrolled portion of the cover to the scaffold. The one or more fasteners may be, e.g., one or more of hooks, ties, loops, buttons, etc., and/or may be releasably or permanently attached to the cover.
[0040] Associated with the above, herewith is also provided a roller device for use in a scaffolding assembly as discussed herein, comprising one or more mountings, e.g. axially opposite mountings for operably mounting to scaffolding in a scaffold, and a rollable scaffold cover material on a core rotatable about the mounting.
[0041] The roller device may comprise a housing at least partly enclosing at least part of the scaffold cover material in the rolled-up configuration.
[0042] Associated with the above, herewith is also provided method of providing a work space for a worker on a scaffold, comprising
providing a scaffold providing the work space for a worker, in particular an elevated work space, and
covering or uncovering at least part of the work space by reversibly (un-)rolling a rollable portion of a cover from (to) a rolled-up configuration to (from) an unrolled configuration using a roller.
[0043] The method may comprise mounting a roller device to the scaffold for, when mounted, reversibly (un-)rolling the rollable portion to (from) the rolled-up configuration from (to) the unrolled configuration for covering and/or uncovering the at least part of the work space.
