Abstract

The invention provides a split bolt end treatment method. The method comprises the steps that two heal blocks are oppositely arranged on inner side walls of two oppositely arranged formworks, and a screw rod of a split bolt penetrates through the heel blocks; after the formworks are fixed by the split bolt, concrete pouring is performed between the formworks; the split bolt and the formworks are removed after concrete pouring is completed, the screw rod of the split bolt is cut and removed, and two ends of the screw rod are located in grooves formed by the heel blocks in a concrete pouring board. According to the method, by arranging the heel blocks between the formworks, and penetrating the split bolt through the middle of the heel blocks, the grooves are formed in poured concrete wall surfaces to facilitate removing of ends of the screw rod of the split bolt to change traditional construction methods and greatly improve construction efficiency, and meanwhile spattering of broken concrete when concrete is chiseled is avoided to improve construction safety. The method has the advantages of being convenient in operation, simple in heel block production method, low in cost and extremely convenient to install.

Description

technical field [0001] The invention relates to the technical field of concrete engineering, in particular to a method for treating the ends of tension bolts. Background technique [0002] At present, when pouring reinforced concrete vertical walls in construction projects, pull bolts are usually used to fix the formwork clamped on both sides of the vertical wall. It is removed, and the pull bolts are left in the vertical wall. At this time, the bolt heads exposed outside the vertical wall are removed to form a complete wall. To deal with the bolt heads leaking outside, the concrete near the bolt heads needs to be chiseled first, and then cut from the wall surface 3 to 5 cm inwards, and finally the pits are blocked with expanded cement mortar to prevent the bolt heads from leaking on the outer surface to achieve anti-corrosion effect . The process of chiseling away the concrete near the bolt head is laborious, and the splashed concrete fragments can easily hurt people. C...
