Embodiment Construction

[0013] A high-efficiency method for plugging holes of through-wall bolts in a shear wall, which adopts the following steps: a. After the concrete of the shear wall is poured and reaches the form removal strength, the formwork is removed and the through-wall bolts are taken out to form a bolt hole 1 with a PVC pipe; b. 1. Select the wooden wedge drill rod 2 and install it on the impact drill I3, start the impact drill I3, and the wooden wedge drill rod 2 gradually drills into the bolt hole 1. When the PVC pipe is found to be loose, turn off the switch of the impact drill I3 and remove the PVC pipe from the Take out in the bolt hole 1; c, after the concrete reaches a certain strength, select the frustum-shaped alloy drill bit 4 to be installed on the impact drill I3, and the retaining wall snap ring 5 is fixed on the conical surface of the frustum-shaped alloy drill bit 4, and then Turn on the impact drill I3, and drill the bolt hole 1 at the outer end of the outer wall. When the...

Abstract

The invention particularly relates to an efficient blocking method for shear wall through-wall bolt holes. The problems, existing in current shear wall through-wall bolt hole blocking, that time and energy are wasted, mortar is wasted seriously, repairing is difficult, and leakage hidden trouble and thermal bridge phenomenon are prone to occur are solved. The efficient blocking method for the shear wall through-wall bolt holes comprises the following steps that a, bolt holes are formed after concrete pouring of a shear wall is finished; b, a wooden wedge drilling pipe is selected and installed on a percussion drill I to drill, and a PVC pipe is taken out; c, a frustum-shaped alloy bit is selected and installed on the percussion drill I, and a flare opening is formed in the external end of the bolt holes; d, glue is applied, and a prefabricated mortar block is fixed to the external end of the bolt holes; e, when grouting is conducted, interfacial agents are centrifugally sprayed on the inner wall of the bolt holes, then expansive cement mortar is sprayed on the surfaces of the interfacial agents and is extruded to the center of the front end of the bolt holes; and f, the inner end of an outer wall is padded manually until compact is achieved. According to the efficient blocking method for the shear wall through-wall bolt holes, constructing efficiency is improved, and meanwhile, occurrence of leakage hidden trouble and thermal bridge phenomenon are thoroughly avoided.

Description

technical field [0001] The invention relates to a sealing method for construction engineering, in particular to a high-efficiency shear wall penetration bolt hole sealing method. Background technique [0002] During the construction of the shear wall, the wall formwork is used as a reinforcement formwork when the formwork is supported, and opposite pull bolts are arranged on both sides of the formwork (in the process of wooden formwork support, in order to facilitate the removal and reuse of the pull bolts, there are PVC casing), the concrete pouring is completed, after the formwork is removed, the pull screw is taken out, so a number of holes are formed on the shear wall (the pull bolts on the shear wall are arranged in a quincunx shape, the distance is about 450-550mm, generally after Calculation OK). [0003] At present, when the hole is sealed, the workers usually use a small ash bucket to fill the hole with mortar little by little, and use a steel bar to tamp it down. ...
