Pouring construction method of combination part between cylindrical component and beam poured by paper tube template

The invention relates to a pouring construction method of a combination part between a cylindrical component and a beam poured by a paper tube template, which is characterized in that: A. a position notch is cut on a paper tube template on the upper part of a cylinder body which is formed in pouring way, is still wrapped by the paper tube template and is close to a poured beam according to the width and the thickness of the beam to be poured, and a cylindrical clamp is arranged on the lower part with a mould cylinder body which is close to the notch; B. a plurality of vertically arranged strip-shaped clamp plate grid bars and an arc purlin enclosure which closely surrounds the clamp plate grid bars are arranged on the cutting part of the paper tube template which is provided with the notch to be consolidated by nails; C. two ends of the arc purlin enclosure are fixedly connected with a clamp plate side mould at two side edges of the poured beam through horse-riding nails, so the formed concrete cylinder body
