DEFLECTION CONTROL METHOD FOR CONSTRUCTION WORK WITH HUGE SPAN

DEFLECTION CONTROL METHOD FOR CONSTRUCTION WORK WITH HUGE SPAN

PURPOSE:To provide a beam with a camber in a simple manner at low cost by cutting off a lower chord member in the construction work of a beam with a huge span so that a cavity is formed, thereby drawing up the respective ends of the lower chord member so as to be connected. CONSTITUTION:The lower ch...

description PURPOSE:To provide a beam with a camber in a simple manner at low cost by cutting off a lower chord member in the construction work of a beam with a huge span so that a cavity is formed, thereby drawing up the respective ends of the lower chord member so as to be connected. CONSTITUTION:The lower chord member 1a of a beam 1 is cut off at its center section so that a cavity section (n) is thereby formed. The respective end sections in the cavity section (n) of the lower chord member 1a are drawn up by means of hydraulic cylinders, jacks and the like, and furthermore, both of the end sections are connected together by means of bolting or welding via connecting members so that the beam 1 is formed with a camber.
