Definitions

  • the present invention relates to a mounting bracket for scaffold boards, a scaffold board and a scaffold according to the preamble of the independent claims.
  • the scaffolding mainly consists of vertical frames, between which are planks or scaffold boards, which make it possible to make the scaffolding.
  • Novel constructions of buildings require increasingly extensive insulation, which are applied to the building envelope. This requires that scaffolding must be set up with a certain distance to the shell. Thus, there is a gap between the scaffolding and the shell, which must also be covered with scaffold boards for the safety of persons and for working. Depending on the thickness of the insulation, which is attached to the building envelope, these additional scaffolding boards must be removed or replaced by narrower scaffold boards.
  • mounting brackets for attachment to scaffolds are known from the prior art, which have a length corresponding to the respective scaffold board.
  • these mounting brackets must be selected to be interchanged depending on the progress of the insulation on the building shell.
  • an additional expense arises when the complete Framework must be adjusted. It is an object of the invention to overcome these and other disadvantages of the prior art. It should be provided a mounting bracket and a corresponding scaffolding board, which allow easy installation and reduce the workload when replacing the scaffolding boards. Also, assembly and disassembly of the mounting bracket and the scaffold boards should be facilitated. This object is achieved by the devices defined in the independent claims. Further embodiments emerge from the dependent claims.
  • the extension arm has at least one and preferably two arrangements of two or more attachment means.
  • the fastening means are arranged in or on the lateral contact surface and can be brought into operative connection with fastening elements of a scaffold board.
  • two lateral contact surfaces are provided on the extension arm, which face each other substantially symmetrically.
  • One or more arrangements of two or more attachment means may also be provided in the second contact surface.
  • Lateral contact surfaces allow accurate and precise placement of scaffold boards on the mounting bracket.
  • forces can be absorbed balanced, a secure connection is also guaranteed.
  • a second or more arrangements of two or more fasteners also allow a scaffold board in different positions to be attached to the mounting bracket.
  • the mounting bracket is preferably designed such that the stop surface has lateral guide surfaces.
  • the mounting bracket With lateral guide surfaces, the mounting bracket can be positioned and secured to the scaffolding element.

  • the forces are thus introduced defined in the scaffolding element.
  • the extension arm likewise preferably has an elongated extension, wherein a longitudinal axis is defined in the direction of this extension.
  • the longitudinal axis of the extension arm is arranged substantially perpendicular to the stop surface.
  • a right-angled arrangement of the longitudinal axis allows a central recording of the force, which thus acts on a defined position of the stop surface.
  • the extension arm of the mounting bracket is made of a hollow profile.
  • Hollow profiles can have round, square or polygonal cross sections.
  • the extension arm is made of a profile which has a C, U, T or H-shaped cross section.
  • Such cross sections increase the strength of the extension arm, since such cross sections usually have a high moment of inertia compared to their weight.
  • Another advantage is that such profiles are directly procured semi-finished.
  • such profiles are made of steel.
  • light metals such as aluminum are also conceivable.
  • the attachment bracket may include attachment means having a first region with a first cross-section and a second region with a second cross-section.
  • the outer dimension of the first cross section is at least 1.1 times, preferably 1.5 times and more preferably at least 2 times larger than the outer dimension of the second cross section.
