Description

Technical Field

[0001] The utility model relates to a grouting sleeve. Background Art

[0002] Grouting sleeves, also known as grouting sleeve joints or sleeve grouting joints, are a combination of specially processed sleeves, matching grouting materials and steel bars. When connecting steel bars, fast-hardening non-shrinkage grouting materials are injected, and the steel bars and sleeves are connected by the bonding and biting action between the materials. Sleeve grouting joints have the advantages of reliable performance, wide applicability, and easy installation. Grouting sleeve connection technology is suitable for reinforced concrete structural engineering, steel structure engineering, bridge engineering, offshore oil production platform engineering, offshore wind power towers and other fields. Grouting sleeve connection technology is a new type of steel structure connection method produced due to the needs of engineering practice and technological development. The emergence of this connection method makes up for the shortcomings of traditional steel structure connection methods and has been rapidly developed and applied.

[0053] In the present technical solution, the fixing plate 3 can be used to increase the stability of the connection between the two steel bars 2 and the sleeve body 1 during grouting. At the same time, the installation component 5 can be used to install the heating component 4 on the outside of the sleeve body 1. The heating component 4 is used to heat the sleeve body 1 to prevent the slurry in the sleeve body 1 from solidifying due to the cold during the grouting operation in extremely cold conditions, thereby avoiding incomplete grouting in the sleeve body 1.
