Assembled wall rebar sleeve grouting process

Abstract

The invention relates to an assembled wall rebar sleeve grouting process. The assembled wall rebar sleeve grouting process comprises the steps that 1, a prefabricated wall is hoisted to be in place; 2, fine adjustment of the wall is carried out, and inclined struts are installed for fixing; 3, edge sealing at the bottom of the wall is carried out, wherein edge sealing at the outer side is achievedin the manner that a polyvinyl chloride foam rubber bar is fixed to a sandwich insulation layer on the lower layer so that the conditions that elastic sealing materials enter a prefabricated wall panel and the structure bearing area is decreased are effectively avoided, edge sealing at the inner side of the wall is achieved through a special edge sealing material, edge sealing is achieved througha special tool, installing seams of the overall wall are subjected to pressure full grouting with grouting materials, the periphery of the bottom of a prefabricated inner wall is sealed with edge sealing materials, sleeve grouting is performed by using a full grouting process, and the cavity at the bottom of the wall is filled during grouting construction; and 4, sleeve grouting is carried out. By means of the assembled wall rebar sleeve grouting process, the reliability of connection and jointing at the bottom of the wall is better ensured, the grouting efficiency and the grouting effect areimproved, construction is made more convenient and effective, and good social, economic benefits and broad application prospects are achieved.

Description

technical field [0001] The invention relates to a grouting process for an assembled wall reinforcement sleeve. Background technique [0002] The common methods of connecting the steel bars at the bottom of the prefabricated walls of prefabricated buildings are two processes: single-sleeve grouting for horizontal seam seat grouting and multi-sleeve grouting for sealing seams with chambers and compartments for horizontal joints. The operation method of single-sleeve grouting for horizontal seam seat grout is as follows: use non-flowing and non-shrinking cement base slurry to lay on the connection surface, and use the seat slurry to block the bottom of each grouting sleeve from the outside world. After the seat grout is solidified, grout each sleeve independently, and grout from the grouting port below the sleeve. The method of multi-sleeve grouting for horizontal seam connecting cavity and sub-compartment sealing is as follows: use non-flowing, non-shrinking seam seat slurry ...

AI Technical Summary

Problems solved by technology

The bottom connection part of the wallboard of the above two processes is divided into a grouting area and a grouting area, that is, both need a grouting process, and the grouting material is a semi-dry material, and the connection reliability with the wall is poor, and the grouting material is applied on the wall On the partition wall of the compartment, the partition wall of the compartment will be deformed, and even the seat slurry will squeeze the sealing sleeve and grouting cannot be performed
