PURPOSE: Bracing equipment is provided to improve stability of work and convenience in the use while removing friction and stress between parts. CONSTITUTION: Bracing equipment has structure wherein a pair of tracks(1) is vertically supported by a bracing frame(4) along trough-type trenches and the tracks support bracing plates(2,3) crossed along adjacent guide grooves of the tracks. A rear flange(6) is welded to the rear of a rectangular main pipe(5) and two side pipes(7) are welded to the sides of the main pipe with a gap from the rear flange. Two front flanges(8) welded to the upper side of the side pipes produce two vertical guide grooves(11) to both sides of the track. The front flanges are projected inward between the side pipes and a guide groove with which the edge of the bracing frame is engaged is produced. A specific end engaged with the vertical groove of the track is formed to the edge of the bracing frame. The bracing frame comprises various connection parts and has rollers to move along the front flanges of the tracks. |
