Embodiment

[0024] Such as Figure 1 to Figure 5 As shown, the tendon connection grouting sleeve for the assembled structure includes a tubular cylinder 4 and a grouting port 1 and a grouting port 2 which are perpendicular to the axial direction of the cylinder 4 and are respectively close to both ends of the cylinder 4 .

[0025] Wherein, the inner cavity of the cylinder body 4 is provided with several inwardly protruding annular inner anchoring protrusions 3 along the axial direction;

[0026] The shape of each annular inner anchoring protrusion 3 matches the tendons 5 arranged in the cylinder 4;

[0027] There are more than two tendons 5 inside the cylinder 4;

[0028] The inner wall of the cylinder body 4 is provided with strip-shaped inner anchoring protrusions 6 extending along the length direction of the cylinder body 4 corresponding to the inner recesses where the outer walls of the two tendons 5 are close to each other.

[0029] In some embodiments, each tendon 5 disposed in th...

Abstract

The invention discloses a bundle bar connection grouting sleeve for a fabricated structure. The bundle bar connection grouting sleeve comprises a tubular sleeve body, a grouting opening and a grout outlet, wherein the grouting opening and the grout outlet are perpendicular to the axial direction of the sleeve body and are close to the two ends of the sleeve body correspondingly. A plurality of annular inner anchoring protrusions protruding inwards are arranged in an inner cavity of the sleeve body in the axial direction; the shape of each annular inner anchoring bulge is matched with that of a bundle rib arranged in the sleeve body; more than two binding ribs are arranged in the sleeve body; and strip-shaped inner anchoring protrusions extending in the length direction of the sleeve body are arranged at the positions, corresponding to the positions where the outer walls of every two bundle ribs are tightly attached, of the inner wall of the sleeve body. The bundle bar connection grouting sleeve for the fabricated structure is suitable for prefabricated part bundle bar connection, two section arrangement forms convenient for pore channel grouting compaction are provided for application of double-limb and three-limb bundle bars, and the blank of domestic bundle bar grouting sleeves is filled.

Description

technical field [0001] The invention relates to the technical field of building tendon connection, in particular to a grouting sleeve for tendon connection of an assembled structure. Background technique [0002] The development of concrete structure construction technology has gone through two stages: cast-in-place concrete construction technology and prefabricated construction technology. The traditional cast-in-place concrete construction technology requires a large number of supports and formwork to be erected on site, and steel bars to be bound. It is noisy, has a great impact on the surrounding environment, and is dangerous. High and inefficient. [0003] Prefabricated concrete structure construction technology is a construction technology that prefabricates the main force-bearing components of the structure in a factory or prefabrication yard, and then transports them to the site for assembly and connection to form a complete structure. Compared with the cast-in-plac...
