Scaffold device for framework

Abstract

Abstract PURPOSE:To increase the supporting strength of brackets by linking supporting members to the end portions of the brackets which are expandably/contractibly installed on the lateral frames on the upper portion of a scaffold frame and mounting the other ends of the supporting members in the optional positions of standard frames via fixtures. CONSTITUTION:A bracket 5 is expandably/contractibly installed on the lateral frame 3 on the upper portion of a scaffold frame 1 and one end of each supporting member 8... is rotatably linked to the end portion thereof. The other end of each supporting member 8... is rotatably linked to each installing member 9... which is optionally mountable on each standard frame 2.... The draw-out length of the bracket 5 can be optionally selected by appropriately moving the mounting position of the installing member 9... up and down. Then, scaffold boards 13, 13 are provided between the lateral frames 3 and between the brackets 5 of adjacent scaffold frames 1. Thereby, the supporting members 8... having a sufficient strength can be used to ensure the support of the brackets 5.
