Description

  The present invention relates to a scaffold plate suitable for the use of a framework scaffold, in which a base board or the like is provided so that a tool or the like does not fall at an end in the width direction of the scaffold.

  For example, in a construction site, when a building is built around a building, a frame body is constituted by a horizontal member erected on the building. The scaffolding plate is constructed on the horizontal member via a hook so as to form a scaffold.

  However, at the construction site, there was a risk of causing an accident due to the danger of spilling nails, bolts, tools, etc., or small building materials from the scaffold plate. Therefore, in recent years, it is important to install a baseboard, a strong cloth, a wire mesh (or mesh sheet), and the like, to prevent falling objects from the width direction end of the scaffold board. . In addition, these cloths, wire nets (or mesh sheets), etc. are called skirting cloth.

Indication of invention

Problems to be solved by the invention

  Therefore, as a prior art, a scaffold board as disclosed in Patent Document 1 has been proposed. The scaffold plate disclosed in Patent Document 1 is hung on a horizontal frame body with a horizontal plate main body and a plurality of hooks provided at both front and rear ends of the plate main body, and on the left and right ends in the width direction of the plate main body. A skirting board provided so as to be rotatable is erected at an end in the width direction of the plate body.

  Specifically, the lower left and right (width direction) lower ends of the board body and the lower base of the base board are joined via hinges, and the left and right (width direction) ends of the board body when the base board rotates around the hinges when used. And is stored behind the plate body when not in use.

  Since the skirting board is integrated with the scaffolding board in this way, after installing the scaffolding board on the frame, it is sufficient to raise the skirting board in sequence, and after installing the scaffolding board, you do not have to carry the skirting board separately. The workability was improved.

  However, when the conventional scaffold plate is used, there are the following problems. For the scaffolding board, hook the hook on the horizontal frame of the frame, set the scaffolding board, and then rotate the baseboard stored on the back side (lower surface) of the board body from the lower surface to the left and right ends in the width direction of the board body. In order to stand on the plate body, the worker on the lower surface side of the scaffolding plate had to be helped to stand up and the operability was poor.

  Therefore, the present inventor tried to construct a baseboard with a hinge portion provided at the outer end in the width direction of the scaffolding board, based on the idea that the baseboard can stand on the upper surface side of the scaffolding board. After standing up, the scaffold board surface became uneven, and when a baseboard with a width reaching about half of the width direction of the scaffold board was raised up, the operability was remarkably deteriorated. Also, since the scaffolding boards are reused for a long time, if the skirting boards are always exposed on the scaffolding board surface, they will impact the skirting boards when they are stored in stacks or transported by trucks. It was assumed that the scaffolding plate itself could not be used because it was damaged and could not be used.

  As described above, the scaffold board according to the present invention can be easily erected by one worker in sequence after the scaffold board integrated with the scaffold board is installed on the frame. The purpose of the present invention is to provide a scaffolding board that can be safely operated at a construction site and that causes less damage to the baseboard cloth even if the scaffolding board is used many times.
