Description

This invention relates to the structure of scaffolding planks used in construction work such as building construction, renovation, and demolition, and more particularly to a scaffolding plank structure that can improve the efficiency of transporting the planks to and from the site, installing them on site, and dismantling them. When constructing, renovating, or demolishing buildings such as houses and office buildings, various types of scaffolding are erected around the building to ensure the safety of workers working at heights and to prevent accidents caused by falling materials, tools, etc. An example of this type of scaffolding is described in Patent Document 1. This scaffolding is constructed by arranging a pair of support columns at predetermined intervals in the beam direction (towards the building), arranging multiple sets of these pairs of columns at predetermined intervals in the girder direction (along the building), supporting each pair of columns in each set to the ground with jacks, erecting horizontal members in the beam direction between each pair of columns, erecting vertical members between adjacent outer and inner columns in the girder direction, erecting treads between adjacent horizontal members in the girder direction, and attaching toeboards facing the girder direction to both ends of each tread in the beam direction. In scaffolding of this configuration, the toeboard consists of a rectangular toeboard body with a large aspect ratio and locking fittings attached to both ends of the toeboard body in the longitudinal direction. The locking portions of the pair of fittings are secured to a pair of horizontal members in the longitudinal direction, thereby attaching the toeboards to both ends of the tread in the beam direction. Furthermore, both ends of the toeboard in the width direction are bent in the same direction to form flanges, which increase the bending strength of the toeboard. Patent Document 2 describes another example of scaffolding. This scaffolding is constructed by bending both ends of the scaffolding board body in the width direction downwards into a U-shape, forming U-shaped left and right plates at both ends in the width direction, each consisting of an outer upright plate, a downward curved side plate, and an inner upright plate. Furthermore, U-shaped covers are attached to both ends of the scaffolding board body in the longitudinal direction, and multiple stiffening members are attached to the underside of the scaffolding body at predetermined intervals in the longitudinal direction. By using scaffolding planks with this configuration, the rigidity of the planks can be increased, and it is possible to prevent workers from being injured by the ends of the planks during the transportation of scaffolding components to and from the site, installation, and dismantling, thereby ensuring worker safety.
