Combining several InterploatingFunction to one

does anyone know how to combine several interpolating functions to ONE
single interploating function?
I now have

Which[0. <= t <= 0.01, InterpolatingFunction[{{0., 0.01}}, "<>"],
        0.01 <= t <= 0.02, InterpolatingFunction[{{0.01, 0.02}}, "<>"],
        0.02 <= t <= 0.03, InterpolatingFunction[{{0.02, 0.03}},

but I would like to have

InterpolatingFunction[{{0., 0.03}}, "<>"][t]

that is piecewise defined from all of the three.
Suggestions please to
