Description

TECHNICAL FIELD The present invention relates to a scaffolding board connector and a scaffolding board connection structure.

At the shield tunnel construction site, a working scaffold is formed by connecting a plurality of scaffolding boards. When connecting two scaffolding boards at a construction site of a shield tunnel, it is necessary to be able to work from above the scaffolding boards because the scaffolding boards are installed above sleepers and brackets. In addition, it is necessary to securely fix the two scaffolding boards at the joint. Furthermore, it is necessary to be able to remove only one intermediate scaffolding board from a plurality of continuous scaffolding boards according to surveying and work contents.

Then, as a connection structure of two scaffolding boards, the ends of both scaffolding boards are inserted into a rectangular tube-shaped connector, and a pin inserted into the mesh of the connector from above is inserted into the hole of the scaffolding board. There is a method in which a coupler is fixed to both scaffolding boards (see Patent Document 1, for example).
