Space framework aerial construction method and push rise device

摘要

PURPOSE:To reduce a cost and to facilitate work by bearing a built-up space truss horizontally at two points by a push-up mechanism, and pushing the space truss up to a height of erection from the existing state for erection. CONSTITUTION:A push-up device is constituted of a base 3 set up to an erection site 2 and a push-up mechanism to push a space truss 4 up to a height of erection so that the base 3 is an anchorage section. The mechanism 5 is constituted of an expansion bearing mechanism 7 consisting of four links 6a - 6d capable of folding and 4 opposite jacks 8. The built-up space truss 4 is born horizontally at two or four points, and it is easily and stably pushed up to any height of erection to maintain. Accordingly, a cost is reduced, and work can be easily carried out.
