Fabricated part grouting layer plugging method and fabricated part connection construction method

Abstract

The invention relates to a fabricated part grouting layer plugging method and a fabricated part connection construction method. The fabricated part grouting layer plugging method comprises the following steps that after a binding wire bypasses a pre-embedded steel bar of a lower part, the two end parts of the binding wire penetrate through a plugging piece which is placed on the outer side of the grouting layer between an upper part and a lower part in advance, and the bottom surface of the plugging piece is in contact with the lower part; and the two parts, penetrating through the two parts of the plugging piece, of the binding wire are bound, the plugging piece is pressed on the side face of the upper part which is hoisted in advance through wire joints formed after binding, the grouting layer is plugged through the plugging piece. The fabricated part grouting layer plugging method is high in construction speed, and the engineering quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of grouting sleeve construction, in particular to a method for sealing a joint grouting layer of an assembled component and a construction method for connecting the assembled component. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] At present, when prefabricated components such as prefabricated wallboards and columns are connected and installed with grouting sleeves, the upper component is first hoisted so that the steel bars of the lower component extend into the grouting sleeve of the upper component, and the gap between the lower component and the upper component There is a certain joint, after the grouting layer is constructed at the joint, the grouting sleeve is then grouted. The traditional construction method of the grouting layer is to wipe the grout at the joint to form ...

[0003] At present, when prefabricated components such as prefabricated wall panels and columns are connected and installed with grouting sleeves, the upper components are hoisted first, so that the steel bars of the lower components extend into the grouting sleeves of the upper components, and the gap between the lower components and the upper components There is a certain joint, after the grouting layer is constructed at the joint, the grouting sleeve is then grouted. The traditional construction method of the grouting layer is to wipe the grout at the joint to form a grout seal, and the grout to be sat After the warehouse is sealed to meet the required strength, the grouting sleeve is then grouted. The inventor found that when using this method of construction, due to the limited operation level of the construction personnel, the thickness of the grout entering the joint is not controlled. When the thickness dimension is too large, it is easy to block the bottom opening of the grouting sleeve, causing the grouting fullness of the grouting sleeve to fail to meet the requirements. If the thickness dimension is too small, the grouting material plugging chamber cannot provide Sufficient sealing force, and when the existing method is used for construction, the grouting construction can only be continued after the slurry seal reaches the set strength, which delays the progress of the project
