Description

Technical Field

[0001] The utility model relates to the field of grouting sleeves, in particular to a non-return anti-slip full grouting sleeve. Background Art

[0002] Grouting sleeves, also known as grouting sleeve joints or sleeve grouting joints, are assembled from a specially processed sleeve, matching grouting material, and rebar. When connecting the rebar, a fast-hardening, non-shrinkage grouting material is injected, connecting the rebar and sleeve through the bonding and interlocking action of the materials. Existing fully grouting sleeves have a simple internal structure during the grouting process, resulting in grout backflow and weak installation security. Therefore, a non-return, anti-slip fully grouting sleeve has been proposed to address these issues. Utility Model Content

[0004] The utility model achieves the above-mentioned purpose through the following technical scheme: a non-return anti-slip full-grouting sleeve, comprising a cylinder, a spiral sheet, a screw hole block, a slot, a slurry inlet pipe and a slurry outlet pipe. A spiral sheet is provided in the cylinder, and screw hole blocks are welded to the ports at both ends of the cylinder. Slots are distributed on the annular surface of the screw hole block. The side wall of one end of the cylinder is connected to and installed with a slurry inlet pipe, and the side wall of the other end of the cylinder is connected to and installed with a slurry outlet pipe.

[0005] Preferably, the screw hole block and the threaded end of the steel bar are threadedly connected to each other.

[0006] Preferably, the inner edge surface of the spiral piece contacts the surface of the steel bar portion located in the cylinder.

[0007] Preferably, the slot is fixedly connected to the adjacent steel bar located on the outside via a connecting piece.

[0008] Preferably, one end of a connecting piece is fixed in the slot, and the other end of the connecting piece is fixedly connected to a slot on another screw hole block.

[0009] Compared with the existing technology, the advantages of the present invention are: by arranging spiral sheets in the cylinder, it is conducive to forming a spiral one-way grouting channel, which plays a role in grouting check; by utilizing the slots on the screw hole block and combining with the connecting parts, the structural function of reinforcing the connection of the grouting sleeve is realized, and the anti-slip property is enhanced.
