Modular scaffold board

A kit of parts from which a modular scaffold board of a plurality of different lengths is constructed, the modular scaffold board being suitable for use instead of and/or alongside conventional seasoned wood scaffold boards in a scaffold structure in which the modular scaffold board and/or conventional seasoned wood scaffold boards are arranged to be supported by transoms positioned beneath the modular scaffold board and/or conventional seasoned wood scaffold boards with a predetermined maximum spacing S between the transoms, the kit of parts comprising:

• a plurality board members including board members of at least two different lengths, each board member being shorter than the predetermined maximum spacing S, each board member having a substantially rectangular cross-section in a transverse plane and extending in a longitudinal direction, perpendicular to the transverse plane, and each longitudinal end of each board member comprising at least one hollow intrusion, extending in the longitudinal direction, forming a female connecting part;
• at least one joining member, which is a separate component from the board members, configured to join the board members together in an end-to-end fashion, so as to enable construction of the modular scaffold board of a plurality of different lengths, the joining member extending in the longitudinal direction and each longitudinal end of the joining member comprising at least one protrusion, extending in the longitudinal direction, forming male connecting part configured to engage with a respective female connecting part of the plurality of board members;
• and
• a locking mechanism configured to releasably lock the board members and joining members in the joined state;
• wherein, when the modular scaffold board is constructed, the male and female connecting parts are configured to provide a connection between board members which gives the modular scaffold board stability under forces exerted in a direction perpendicular to the longitudinal direction, such that said stability under said forces is equal to, or surpasses, that of a conventional seasoned wood scaffold board of the same length, such that the modular scaffold board is able to support at least the weight of a person when supported by transoms with the predetermined maximum spacing S, in the scaffold structure.
