Creating horizontal support beams for helix slide

Hi, so I am making a spiral slide with varied pitch and I need to make horizontal structural beams attached on the inside of each helix tube extending inwards towards a central core. (like that in my attached image)

Does anyone know how to do that so the number of horizontal structure follows the number of turns I vary in my model? I have attached the file below. helix slide.3dm (135.3 KB) (20.0 KB)
