here is disclosed a system designed for the quick placing of concrete form- supporting braces. It is composed of the perpendicular beam 1 and the horizontal one 2; both of the foregoing beams are of standardized length and interconnected with the connecting angle 4 and the diagonal support 9 which varies in length to support the changing inclinations of the vertical beam 1 whereto there is attached the beam extension 10, or the beam connecting element 17, the angles 8 fixing the braces, and the clamp 11 of the pipe 12 used for the alignment of an array of systems. The assembly of the accessories is realized by means of safety pins 7 and 9a, with no need of tools. The connection of the system with braces is effected by nailing the related surfaces of the beam extension 10a, the beam-connecting angle 4a, and the brace-connecting angles 8 onto said braces. The system is practicable for varying embodiments; it is easily dismounted and reusable many times. |
