The utility model has the advantages of high structural strength, low production cost, simple and convenient processing, convenient operation for workers, and the like.
Description
Technical Field
The utility model relates to a steel bar connection construction technical field especially relates to a steel bar connection is with full grout sleeve with two-way centering barb.
Background
Ordinary full grout sleeve selects cast iron to make and forms, does not own possess the grout mouth, so when carrying out the grout operation, the operation is very inconvenient, simultaneously because grout sleeve inner wall is more smooth, the adhesive capacity between the remaining lateral wall after the slurry gets into is less, can influence the firm degree between slurry and the sleeve, in order to solve above-mentioned problem, it is very necessary to design a new grout sleeve.
Disclosure of Invention
The utility model aims to solve the technical problem of providing a full grouting sleeve with bidirectional centering barbs for connecting steel bars, which is characterized in that a sleeve barrel is directly punched and formed by a seamless steel tube, simple grouting holes and positioning pin technology are combined, and the production and manufacturing process of the grouting sleeve is simplified; the inner wall of the cylinder body is protruded to form bidirectional centering barbs through a stamping process, so that the connection between the slurry and the sleeve is firmer.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a full grout sleeve is used in connection of steel bar with two-way centering barb, it is protruding including sleeve body, grout mouth and barb, sleeve body inner wall on evenly arranged four rows of barb arch, the outer lane of sleeve body on be provided with four rows of barb breach of the protruding one-to-one of four rows of barb, sleeve body side on be provided with two installing ports, install the grout mouth on the installing port.
As a supplement to the technical scheme, the outer ring of the upper part of the grouting opening adopts a threaded structure, and the lower end of the grouting opening is provided with a bayonet matched with the mounting opening.
As a supplement to the technical scheme, the middle part of the side surface of the sleeve body is provided with a conical hole with a large upper part and a small lower part, and a positioning bolt is inserted and installed in the conical hole.
Has the advantages that: the utility model relates to a full grouting sleeve with bidirectional centering barbs for connecting steel bars, which is characterized in that a sleeve barrel is directly punched and formed by a seamless steel tube, simple grouting holes and positioning pin technology are combined, and the production and manufacturing process of the grouting sleeve is simplified; the inner wall of the cylinder body is protruded to form bidirectional centering barbs through a stamping process, so that the connection between the slurry and the sleeve is firmer. The utility model has the advantages of high structural strength, low production cost, simple and convenient processing, convenient operation for workers, and the like.
Drawings
Fig. 1 is a structural view of the present invention.
The figure is as follows: 1. sleeve body, 2, barb are protruding, 3, barb breach, 4, grout mouth, 5, bayonet socket, 6, location bolt.
Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
This technical scheme a steel bar connection is with full grout sleeve with two-way centering barb, its embodiment is as shown in fig. 1, protruding 2 including sleeve body 1, grout mouth 4 and barb, 1 inner wall of sleeve body on evenly arranged four rows of barb arch 2, sleeve body 1's outer lane on be provided with four rows of barb breach 3 of the protruding 2 one-to-one of barb, sleeve body 1 on be provided with two installing ports, install grout mouth 4 on the installing port.
According to the technical scheme, the sleeve body 1 selects steel to replace cast iron to increase the fatigue resistance of the sleeve, the anti-seismic performance of the connection joint is improved, meanwhile, the seamless steel tube is directly punched and formed into the sleeve body, the machining process is greatly simplified, when the operation is carried out, slurry enters the sleeve body 1 from the grouting opening 4, the barb on the inner wall of the sleeve body 1 protrudes 2, adhesive force is formed on the slurry, the connection strength between the barb and the slurry is greatly improved, and the slurry is not prone to slipping after solidification.
As a supplement to the technical scheme, the outer ring of the upper part of the grouting opening 4 is of a threaded structure, the lower end of the grouting opening is provided with a bayonet 5 matched with the mounting opening, and the bayonet 5 is of a conical ring mounting structure, so that the grouting opening 4 is conveniently butted with the sleeve body 1.
1 side middle part of sleeve body be provided with big-end-up's circular cone hole, the downthehole inserting of circular cone installs location bolt 6, location bolt 6 is used for extrudeing the slurry of solidifying soon for it is inseparabler when the slurry solidifies, the improve quality.
The embodiments described herein are merely exemplary and various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope and spirit of the invention as defined by the claims.
