METHOD FOR STRETCHING THE SKIN PLATES ON THE CONSTRUCTION SKELETONS FOR STRETCHING THE PLATES ON THE CONSTRUCTION SKELETONS IN VEHICLES, ESPECIALLY IN BUSES AND DEVICE FOR APPLICATION THEREFOR

摘要

1. A method for tensing sheet steel on vehicle bodies, in particular for buses/coaches, characterized in that one end of the sheet (45) of the side wall plating is durably fixed with the bus body structure, and the other end is bent at the angle of 90 degrees and put between the fastening bar (15) and the insert (16) and is pushed against the shorter bent side with screws (18), and on the longer side with clamps (17), and this end is primarily adjusted with screws (20, 21) and then is subject to a one-side tensing with hydraulic actuators (25, 26) with a coinstant force so that the sheet (45) of the side wall plating touches the bus body; this touch is held till the sheet (45) of the side wall plating is durably fixed with the bus structure.2. A device for tensing sheet steel on vehicle bodies, in particular for buses/coaches; that device is outfitted with hydraulic actuators, clamps, and screws, characterized in that the device includes a U-shaped main frame (1), and a sliding frame (13) inside the main frame; whereas the main frame (1) includes hinge-mounted clamping units (7, 8), those clamping units include an outrigger (9) and a support (10) joined turnably with each other, and an additional adjustment screw (11) and protection pin (12) [à]IMAGE
