Abstract

The invention discloses a construction method for split bolt hole plugging. The construction method comprises the following steps of: S1: cleaning a hole: cleaning a split bolt hole on a shear wall, i.e., utilizing a hair brush to remove laitance and residues in the hole, and removing residual mortar around the hole to keep the inner wall of each bolt hole clean; and S2: removing a PVC (polyvinylchloride) pipe: adopting chiseling and expanding processing on the end part of the hole, removing the exposed PVC pipe by a scraper knife, and after cleaning is finished, cleaning the residual mortararound the hole by the hairbrush. According to the construction method, through a way that an antiseptic wooden plug and inner expansive grout are cooperated for plugging, a traditional end grout andinternal foaming plugging technology is replaced, hole plugging quality is guaranteed, the problems that cracking and falling are likely to happen can be effectively reduced, a hidden danger that an exterior wall is likely to generate water seepage in a later stage can be reduced, and construction quality is improved. In a plugging construction process, a special machine is adopted to replace a manual foaming way, so that construction efficiency is high, construction speed is high, and meanwhile, a manpower burden is lightened.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for plugging holes of pull bolts. Background technique [0002] Shear wall is a wall in a house or structure that mainly bears horizontal and vertical loads caused by wind loads or earthquakes to prevent the structure from being damaged by shearing. There are multiple tie bolt holes in the shear wall, and the holes of the tie bolts need to be blocked during the construction process. [0003] At present, the traditional plugging process is pouring polyurethane foaming agent, and the two ends are plugged with mortar. figure 1 As shown, after the bolt hole is foamed, the mortar at both ends of the plugging method is extremely difficult to seal, and it is very easy to crack and fall off, leaving hidden dangers of water seepage for the outer wall in the later stage. At the same time, the plugging method is a flexible structure. In the later period...
