Abstract
The utility model discloses a grout sleeve. A grouting sleeve comprises a grouting sleeve body, wherein the grouting sleeve body comprises a field assembly end, a prefabricated end, a slurry inlet and a slurry outlet, the vertical section of the root of a shear groove arranged on the inner wall of the grouting sleeve body is a cambered surface smooth connection structure with the left side and the right side inclined correspondingly, the left inclined cambered surface angle of the vertical section of the root of the shear groove is 15-17 degrees, and the right inclined cambered surface angle is 33-35 degrees; the grouting sleeve body is made of a seamless steel pipe. The utility model discloses prevented to leave the remaining emergence that leads to filling the not enough phenomenon of thick liquids of air when grout sleeve body fills thick liquids, improved the internal reinforcing bar of grout sleeve and drawn the interior holding reinforcing bar power that produces, prevented that the reinforcing bar from drawing and take off the phenomenon, improved grout sleeve prefabricated component's structural strength.
Description
Technical Field
The utility model belongs to a thick liquid anchor formula muffjoint spare that is used for steel bar connection between the precast concrete component especially belongs to a grout sleeve.
Background
Grout sleeve is generally applied to fabricated construction, uses grout sleeve prefabricated component to insert the ribbed steel bar into the grout sleeve that the inner chamber is unsmooth surface, through pouring into special high strength cement base grouting material to the clearance of grout sleeve body and reinforcing bar, with the reinforcing bar anchor in the sleeve body after the grouting material solidifies. In the prior art (as the attached figure 1 of the specification), two problems occur due to the fact that the shear groove position of the grouting sleeve body is not smooth enough: firstly, grouting materials are grouted into the interior of a grouting sleeve barrel, air residues are easily left due to the approximately straight structural reason of the root part of a shear groove of the grouting sleeve barrel, insufficient grouting is easily caused, and the structural strength of a prefabricated component of the grouting sleeve is affected; secondly, because the shear groove of the grouting sleeve body is approximately straight, the steel bar is not easy to tightly hold when the steel bar is pulled, and the phenomenon of pulling off the steel bar sometimes occurs. How prevent to grout sleeve body and leave the emergence that the air is remaining when filling the thick liquids and remaining the not enough phenomenon of thick liquids, how improve the cohesion reinforcing bar power that produces when the internal reinforcing bar of grout sleeve is pulled, prevent that the reinforcing bar from pulling off the phenomenon, improve the structural strength of grout sleeve prefabricated component and be the problem that needs the solution.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: a grout sleeve is provided. The grouting sleeve can prevent the phenomenon that the air residue is left when the grouting sleeve body is filled with slurry, so that the insufficient slurry is filled, the tightly-holding reinforcing steel bar force generated when the reinforcing steel bar in the grouting sleeve body is pulled can be improved, the phenomenon that the reinforcing steel bar is pulled off is prevented, and the structural strength of the prefabricated component of the grouting sleeve is improved.
The utility model provides a technical scheme of above-mentioned technical problem is: the utility model provides a grout sleeve, includes grout sleeve body, grout sleeve body is including on-the-spot assembly end, prefabricated end, advances thick liquid mouth, grout outlet, characterized by: the vertical section of the root part of the shear groove arranged on the inner wall of the grouting sleeve body is a smooth connection structure with cambered surfaces, the left side of the vertical section of the root part of the shear groove is correspondingly inclined, the angle of the cambered surface, inclined at the left side, is 15-17 degrees, and the angle of the cambered surface, inclined at the right side, is 33-35 degrees;
the grouting sleeve is one of a semi-grouting sleeve or a full-grouting sleeve;
the grouting sleeve body is made of a seamless steel pipe.
The utility model has the advantages that: because the utility model discloses the vertical cross-section of shear force groove root that sets up on the grout cover barrel inner wall is the smooth connection structure of cambered surface of the corresponding slope in left and right both sides, and the cambered surface angle of the vertical cross-section left side slope of shear force groove root is 15-17, and the cambered surface angle of right side slope is 33-35. The technical problems that in the prior art, air residues are easily left in the structure of the shear groove root part of the grouting sleeve body, insufficient grouting is easily caused, the structural strength of a prefabricated part of the grouting sleeve is influenced, the steel bar holding force is not easily generated when the steel bar is pulled, and the steel bar is sometimes pulled off are solved; the utility model discloses prevented to leave the remaining emergence that leads to filling the not enough phenomenon of thick liquids of air when grout sleeve body fills thick liquids, improved the internal reinforcing bar of grout sleeve and drawn the interior holding reinforcing bar power that produces, prevented that the reinforcing bar from drawing and take off the phenomenon, improved grout sleeve prefabricated component's structural strength.
