Rigid connecting type half-grouting sleeve connector

Abstract

The invention discloses a rigid connecting type half-grouting sleeve connector which comprises a grouting sleeve body, a rigid connecting positioning column and a T-shaped dowel, wherein two circular grouting holes are formed in the outer wall of the grouting sleeve body; the rigid connecting column is column-shaped; a connecting screw rod for connection and fixation is arranged at one end of the rigid connecting column. By adopting the rigid connecting type half-grouting sleeve connector, a conventional mode of fixing a grouting sleeve is abandoned, flexible material connection is not adopted any longer, and under the condition that use and mounting are not affected, rigid connection positioning is achieved through up and down grouting slurry discharge holes of the grouting sleeve; due to adoption of fixation and positioning of a dowel structure, rigid connecting pieces can be achieved, mounting, fixation and combination of the grouting sleeve can be facilitated, the mounting time is greatly shortened for operators, and the mounting difficulty is greatly alleviated for the operators; the positioning structure is simple and easy to operate and high in positioning precision and reliability; the general defect that the grouting sleeve is not solidly combined and fixed with a mold plate surface can be effectively avoided, and the sleeve can be solidly combined with the mold plate surface by virtue of rigidity of the sleeve self.

Description

technical field [0001] The invention relates to a grout-anchored sleeve connector used for connecting steel bars between concrete components, in particular to a rigidly connected semi-grouted sleeve joint. Background technique [0002] At present, grout-anchor sleeve connections are widely used to connect steel bars between concrete members, and flexible connection methods are usually used. When using flexible connectors, such as rubber parts, the grouting sleeves are prone to be stuck, resulting in not only time-consuming and labor-intensive installation, but also As a result, the installation accuracy is not good, and the verticality and the tightness of the combination with the formwork surface cannot be guaranteed. Secondly, the service life of rubber and plastic is very short. After repeated use, the parts are prone to serious problems such as aging, falling off, and damage; The steel bar is directly separated from the panel when it vibrates, and the whole component wi...

When using flexible connectors, such as rubber parts, the grouting sleeves are prone to be stuck, resulting in not only time-consuming and labor-intensive installation, but also Leading to poor installation accuracy, verticality, and tightness with the formwork surface cannot be guaranteed

Secondly, the service life of rubber and plastic is very short. After repeated use, the parts are prone to serious problems such as aging, falling off, and damage; When the steel bar is directly separated from the panel during vibration, the whole component will be scrapped and the serious consequence will be
