A construction method for pulling bolts in the formwork of the wall. Two parallel formworks are set at the position of the wall body to be poured, the sleeve is passed through the formwork, several clamps are hoisted above the formwork, the fixing bolts of the clamps are connected by a fixing bar, and the fixing nuts are Tighten the fixing bolts to fix the fixing rod; pass the
steel bar through the template and the fixture, so that the
steel bar passes through the sleeve; set a number of sealing gaskets at both ends of the
steel bar, and set sealing nuts outside the sealing
gasket; set the top end of the adjacent angle steel
pipe Insert the two sides of the connecting rod, cover the angle steel
pipe with the limit block and fix the connecting rod, set the sealing steel plate connected with the angle steel
pipe at the bottom of the angle steel pipe, make the sealing steel plate connect with the bottom of the template, and connect the angle steel pipe with the steel bar; Pour
reinforced concrete into the gap between the clamps; remove the sealing steel plate, limit block, connecting rod, angle steel pipe, sealing nut, sealing
gasket, steel bar, fixing nut, fixing rod, clamp and formwork; the sleeves on both sides of the wall will be exposed The
barrel is
cut, and the sealing cover is welded on both sides of the
barrel.
