METHOD FOR CONSTRUCTING STEEL TRUSSED CONSTRUCTION

摘要

PURPOSE: To enhance the safety and efficiency of operations by reducing as much of operations at high places as possible. ;CONSTITUTION: When a steel trussed construction 1 is to be constructed which has a lower structural body 20 comprising plural pairs of steel poles 2 provided at intervals L1 in the directions of the arrows A, B and which has an upper structural body 21 formed by the connecting together of a plurality of trussed girders 5 by means of connecting members 6 and supported against the lower structural body 20, a structure unit having the plural pairs of steel poles 2 and the plurality of trussed girders 5 is constructed (first process). A roof truss 3 that can be supported on the plural pairs of steel poles 2 arranged at the intervals L1 is assembled on the ground with the plurality of trussed girders 5 interconnected, and is hoisted and installed on the plural pairs of steel poles 2 arranged at the intervals L1, with the roof truss 3 separated by one interval L1 from each of already constructed structure units in the directions of the arrows A, B so that a preceding structure unit is constructed (second process). The structure unit and the preceding structure unit are connected together to construct an extended structure unit. An operation cycle comprising the first and second processes is performed once or more.;COPYRIGHT: (C)1996,JPO
