Problems solved by technology

[0002] There are protruding steel bars at both ends of the prefabricated beams and slabs, which are connected with cast-in-place beams and slab steel bars. Therefore, the surface of both ends of the beams and slabs needs to be chiseled. The traditional chiseling method is manual chiseling with pneumatic picks, which has high construction intensity and is time-consuming and laborious. Moreover, the chiseling quality is not high, the chiseling with the pick is louder, and there is more dust; the chiseling is not in place at the end of the beam and the extending ribs of the slab, part of the slurry skin is not completely chiseled, the depth is not enough, and the stones are not completely exposed The joint surface, in the subsequent cast-in-place beam-slab joint, affects the bondability of new and old concrete

Embodiment 1

[0069] A kind of water flushing chiseling process for concrete members, comprising the steps of:

[0070] S1: bottom tire treatment

[0071] Check the bottom tire to ensure that the surface of the bottom tire is smooth and clean, the sidelines are straight and free of pits, the rubber strips on both sides of the bottom tire are intact, and there is no slag between the rubber strip and the bottom tire. The iron surface on both sides of the bottom tire surface should be Ensure smoothness and tight fit with the wooden square, ensure that the iron sheet does not bulge, and there is no ash under the iron sheet and the wooden square. When there is ash on the bottom tire, local settlement, cracking, rubber strip damage, iron sheet damage, and ash inclusions, Repair or replace the bottom tire;

[0072] S2: Apply release agent

[0073] Apply release agent evenly on the treated bottom tire, the release agent should not be too thick, to avoid oil accumulation on the bottom tire, so as ...

The iron surface on both sides of the bottom tire surface should be Ensure smoothness and tight fit with the wooden square, ensure that the iron sheet does not bulge, and there is no ash under the iron sheet and the wooden square. When there is ash on the bottom tire, local settlement, cracking, rubber strip damage, iron sheet damage, and ash inclusions, Repair or replace the bottom tire;

[0102] S2: Apply release agent

[0103] Apply release agent evenly on the treated bottom tire, the release agent should not be too thick, to avoid oil accumulation on the bottom tire, so as ...

Embodiment 3

[0129] A kind of water flushing chiseling process for concrete members, comprising the steps of:

[0130] S1: bottom tire treatment

[0131] Check the bottom tire to ensure that the surface of the bottom tire is smooth and clean, the sidelines are straight and free of pits, the rubber strips on both sides of the bottom tire are intact, and there is no slag between the rubber strip and the bottom tire. The iron surface on both sides of the bottom tire surface should be Ensure smoothness and tight fit with the wooden square, ensure that the iron sheet does not bulge, and there is no ash under the iron sheet and the wooden square.

Abstract

The invention discloses a concrete member water-washed chiseling process. The process comprises following steps of S1, bottom body treatment; S2, isolation agent painting; S3, mold plate cleaning andchecking; S4, exposed aggregate agent stirring; S5, exposed aggregate agent spraying on the mold plate surface; S6, mold plate supporting; S7, concrete casting; S8, mold plate dismounting; S9, concrete surface checking; S10, high-pressure water gun flushing; S11, flushing result acceptance inspection; and S12, maintenance. The high-pressure water-washed chiseling process is used, concrete laitanceon the side face of a beam plate can be effectively flushed away, aggregate is evenly exposed, bonding firmness of new and old concrete can be effectively ensured, compared with traditional chiseling, water-washed chiseling cannot destroy part corners, finished product protection is facilitated, construction quality is improved, the process is easy to operate, the labor intensity is low, manual work and time can be saved, construction efficiency is greatly improved, cost is saved, in the construction process, noise and dust cannot be generated, and the process is environment-friendly.
