Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a novel MIC precast component grouting sleeve positioning structure. Background Technology

[0002] During the production of MIC (Modular Integrated Building) components, due to special structural requirements, grouting sleeves need to be added to the bottom of the corresponding post-cast columns. This design is mainly to achieve vertical connection during subsequent chassis installation. However, because the overall structure of MIC components is large, and there are numerous grouting sleeves at the bottom, and the positional accuracy of the grouting sleeves directly affects the success of chassis installation, the positional accuracy requirements for the grouting sleeves are extremely high.

[0003] Traditional methods for positioning grouting sleeves primarily involve drilling holes in the panel and using grouting sleeve plugs to secure the sleeves. However, this method presents several problems when applied to MIC (Made in-house) components. First, worker installation of grouting sleeve plugs is inefficient and unsuitable for large-scale, high-efficiency production. Second, various factors during installation, such as improper operation and material deformation, often lead to positional deviations in the grouting sleeves, resulting in low accuracy and impacting the installation efficiency and quality of the chassis. Furthermore, grouting sleeves typically come in various diameters, such as 600mm, 800mm, 1000mm, and 1200mm. Traditional positioning methods require preparing plugs that match the sleeve diameter, undoubtedly increasing material costs and management complexity. Utility Model Content

[0004] The purpose of this utility model is to solve the problems mentioned above in the background technology and to propose a new type of MIC precast component grouting sleeve positioning structure.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0012] As a further embodiment of this utility model: the upper part of the connecting rod is a smooth rod, the collar can slide vertically on the smooth rod, and the lower part of the connecting rod has a thread on its outer surface that mates with the nut.

[0013] As a further embodiment of this utility model, the top cover and the connecting rod are connected and fixed by a connecting part.
