In pedestal construction of steam turbine nowadays, split heads is used as the prevailing rebar strengthening method for which the welding workload, time required, and rebar wastage are considerable. Based on the shortcomings of the traditional method, a triangle stay bearing replacing split head for pedestal rebar strengthening is introduced, where the construction time may be shortened, rebar be saved, and hence economical benefit is enhanced.By using triangle stay bearing, duration can be shortened, rebar can be saved hence more economizing.
