Definitions

  • the present invention relates to a scaffolding with a roof section, a scaffold system, a crane, and a method for erecting a scaffolding.
  • a scaffold is a temporary platform for raising and supporting scaffold workers and materiel during construction, maintenance and repair of buildings, bridges, and large machinery.
  • the scaffolding comprises one or more sections of suitable size depending on the form and application.
  • a roof construction may also be added to the scaffold, which can protect the building and the scaffold workers against wind and weather.
  • one or more scaffold workers When working on a narrow platform or no platform at all, one or more scaffold workers will have access to the roof construction, so that the roof sections can be hung one by one from a crane with the help of slings or chains, etc. After this, the roof sections can be lifted down with the aid of a crane or placed elsewhere on the top of the scaffold.
  • the scaffold workers should use the proper materials and safety gear when the roof sections are being fastened to the crane in order to avoid accidents.
  • the work is far from safe for the scaffold worker to perform, even if the scaffold worker is using a safety line.
  • the scaffold workers who set up and take down the roof sections on or off the scaffold roof construction must use the necessary safety gear and materials to make sure that both the scaffold workers, the roof sections, and the scaffold are protected before, during, and after the work task.
  • the purpose of the invention is to provide a roof section which can be quickly and easily mounted and dismounted without risk to the scaffold workers, and to provide a method for building a roof construction on a scaffold that will reduce the expenses of setting up and dismantling and save on work time.
  • the invention comprises a roof section for use in a scaffolding, which roof section can be mounted as the top on a scaffolding, and which roof section comprises a section frame and at least one lifting yoke fastened to the section frame, where the lifting yoke is provided such that the lifting gear on a crane can enter into releasable engagement with the lifting yoke when hooking up and unhooking the roof section on the crane, in that the lifting yoke comprises grasping means which are congruent with the lifting gear on the crane, and in that the lifting yoke extends permanently further upward from the section frame, and the grasping means are permanently situated further upward at a distance from the section frame, wherein the lifting yoke is provided such that the lifting gear on the crane can hook up the lifting yoke without the aid of scaffold workers, and such that the lifting gear on the crane can unhook the lifting yoke without the aid of scaffold workers.
  • a roof construction can be part of a scaffolding at a construction site as a temporary roof.
  • the roof construction may consist of one or more roof sections. Roof sections are arranged alongside each other in a predetermined position in the roof construction.
  • the roof section comprises a fixed lifting yoke for use during an automatically releasable gripping connection between the lifting yoke on the roof section and the lifting gear on a crane.
  • the roof section may be provided with a tarpaulin, which can be fastened to the section frame.
  • the lifting yoke for example may be fastened to the sides of the section frame.
  • the lifting yoke alternatively may be fastened to the middle or partly to the middle of the section frame.
  • the lifting yoke may be part of the section frame, which will ensure a firm and stable connection between the lifting gear and the section frame.
  • the present invention provides a solution for a roof section which is quick and easy to mount, to move to another position, and to dismount.
  • the expenses for set-up during the mounting and the taking down during the dismounting of the roof construction are significantly reduced and valuable work time is saved.
  • the roof construction's section frames can be automatically fastened to and released from the crane's lifting gear without manual switching from fastened to released state performed by a scaffold worker. Therefore, the risk of the scaffold worker becoming injured or, in the worst case, a fatal accident occurring at the construction site caused by manipulation of the roof sections is significantly reduced. And the time it takes to mount, move or dismount the roof construction is likewise significantly reduced.
  • the lifting yoke may be part of the section frame or arranged such that the lifting yoke or portions of the lifting yoke are placed at a predetermined distance from the section frame.
  • the lifting yoke for example may extend from the one side of the section frame to the opposite side of the section frame.
  • the lifting device may be provided at the middle of the lifting rod or be formed as part of the lifting rod.
  • the lifting rod may be formed as an arc away from the section frame. It is also possible to use two lifting devices, which are arranged such that the first lifting device is secured to the one side of the one side of the section frame and a second lifting device is fastened to the opposite side of the section frame, where for example the lifting rod is arranged between the first lifting device and the second lifting device.
  • the center of gravity may be found for example from the dimensions of the roof section and the estimated weight distribution.
  • the lifting rod and the lifting device can be arranged such that the weight distribution is optimal when the roof section is lifted and moved by the crane. This can reduce and/or prevent accidental instability when the crane is lifting and moving the roof section to a new placement on the scaffold.
  • Said lifting yoke comprises at least two levers and a grasping element, where a first fastening end on the levers is fastened to section frames of the roof section, and a second fastening end on the levers is fastened to said grasping element.
  • the lifting yoke for example may be formed from four levers mounted as in a pyramid, where a first lower tip of the pyramid is fastened to the one side of the section frame, a second lower tip of the pyramid is fastened to the other side of the section frame, a third lower tip of the pyramid is fastened to the other side of the section frame and a third lower tip of the pyramid is fastened to the other side of the section frame, and where a first upper tip of the pyramid comprises the grasping element for the lifting gear on the crane.
  • One end of the levers constitutes the lower tips of the pyramid, and the other end of the levers is secured to the grasping element.
  • the crane's lifting gear can thus be easily accommodated to perform the hooking up and unhooking.
  • the grasping element may comprise a coupling sleeve at a predetermined distance further upward from the upper part of the roof section, which coupling sleeve is equipped with fastening means for fastening the second fastening end of at least two levers to the coupling sleeve, so that the second fastening end of the at least two levers is joined via the coupling sleeve in relation to each other and joined to the grasping element.
  • Another benefit of arranging the grasping element at a predetermined distance further up in relation to the upper part of the roof section is that the crane's lifting gear cannot accidentally destroy the tarpaulin which is part of the roof section.
  • the grasping element comprises a shield, which shield protects at least the second fastening end of the levers from parts of the surroundings, such that the lifting gear on the crane, when the lifting gear during the hooking up is brought into engagement with the grasping element, is prevented form coming into contact with the second fastening end of the levers.
  • the roof section may be provided with a plurality of lifting devices arranged in a predetermined pattern dictated by the dimensions and weight of the roof section, and possibly weather conditions and so forth.
  • the arranging of the lifting devices is critical in relation to the center of gravity.
  • a lifting yoke on a roof section can be provided by fastening a plurality of lifting devices, a plurality of levers and a plurality of retention rods in combination relative to each other.
  • a lifting gear of a crane which lifting gear comprises at least one locking device with a releasable locking mechanism, where the locking device in use can take hold of a locking device arranged on a lifting yoke, which is fastened to a roof section, where the roof section can be mounted as a top on the scaffolding, and which roof section comprises a section frame and at least one lifting yoke fastened to the section frame, where the lifting yoke is provided such that the lifting gear on a crane can enter into releasable engagement with the lifting yoke when hooking up and unhooking the roof section on the crane, in that the lifting yoke comprises grasping means which are congruent with the lifting gear on the crane, and in that the lifting yoke extends permanently further upward from the section frame, and the grasping means are permanently situated further upward at a distance from the section frame, wherein the lifting yoke is provided such that the lifting gear on the crane can hook up and unhook the lifting yoke without the aid of scaffold workers.
  • the lifting gear one may use for example grasping claws or a hook for the hooking up.
  • the hooking up and unhooking is done without handling by a scaffold worker.
  • the automatic releasable locking mechanism may be mechanical, hydraulic, or electric, for example.
  • the lifting gear may be controlled remotely, for example by a crane operator, or by activation when the lifting yoke and the lifting gear are brought together.
  • a scaffold worker furthermore may also control the hooking up and unhooking at a safe distance from the roof section.
  • the lifting yoke with grasping means is congruent with the lifting gear on a crane, which lifting yoke has at least two levers, which extend further upward, and the grasping means is situated at the upper ends of the at least two levers, and where the lifting yoke can be provided on a roof section, where the roof section can be mounted as a top on the scaffolding, and which roof section comprises a section frame and at least one lifting yoke fastened to the section frame, where the lifting yoke is provided such that the lifting gear on the crane can enter into releasable engagement with the lifting yoke when hooking up and unhooking the roof section on the crane, and in that the lifting yoke extends permanently further upward from the section frame, and the grasping means are permanently situated further upward at a distance from the section frame, wherein the lifting yoke is provided such that the lifting gear on the crane can hook up and unhook the lifting yoke without the aid of scaffold workers.
  • the invention also relates to a crane for hooking up and unhooking a roof section of scaffolding, which crane comprises a lifting gear, which comprises at least one locking device with a releasable locking mechanism, where the locking device can grasp a grasping element arranged on a lifting yoke, which is fastened to the roof section, where the roof section can be mounted as a top on the scaffolding, and which roof section comprises a section frame and at least one lifting yoke fastened to the section frame, where the lifting yoke is provided such that the lifting gear on the crane can enter into releasable engagement with the lifting yoke when hooking up and unhooking the roof section on the crane, in that the lifting yoke comprises grasping means which are congruent with the lifting gear on the crane, and in that the lifting yoke extends permanently further upward from the section frame, and the grasping means are permanently situated further upward at a distance from the section frame, wherein the lifting yoke is provided such that the lifting gear on the crane
