Abstract

The invention relates to a grouting sleeve with multi-point-distributed inner cavity bulges and a manufacturing method thereof. The grouting sleeve comprises a metal pipe, wherein the two ends of an inner cavity of the metal pipe are provided with the plurality of bulges correspondingly, the bulges are arranged towards the central axis of the metal pipe, the bulges can restrain grouting materialspoured in the metal pipe, the bulges are uniformly distributed in the axial direction and the circumferential direction of the metal pipe, stress concentration of the metal pipe at the bulges is reduced, each bulge comprises a vertical face and an inclined face, the vertical faces are perpendicular to the central axis of the metal pipe, the vertical faces are arranged on one sides, close to the center of the metal pipe, of the inclined faces correspondingly, the plurality of columns of bulges are arranged in the axial direction of the metal pipe, a corresponding thrust-stopping inclined tableis formed between the every two adjacent bulges in the same column, and the heights of one ends, close to the center of the metal pipe, of the thrust-stopping inclined tables are smaller than the heights of one ends, away from the center of the metal pipe, of the thrust-stopping inclined tables.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a multi-point distributed grouting sleeve with inner cavity protrusions and a manufacturing method thereof. Background technique [0002] The prefabricated concrete structure has the advantages of high degree of industrialization, saving materials, less pollution, convenient construction, less wet work on site and the number of workers, easy control of the quality of prefabricated components, short construction period, and fast investment recovery. It is the direction of the industrialization of new buildings. . The cost of steel bar connection is an important factor affecting the construction cost of prefabricated structures. [0003] At present, the reinforcement connection methods of prefabricated components mainly include grout-anchor lap connection and sleeve grouting connection. The latter has a wider scope of application because it is not limited by...
