Abstract

The invention discloses a full grouting sleeve for connecting of three-bundled-bar bundles and a connecting method of the three-bundled-bar bundles. The full grouting sleeve comprises a metal sleeve body (containing limiting stop blocks), two sealing rings and a grouting structure, wherein the metal sleeve body is used for connecting two sections of three-bundled-bar bundles (three-bundled-bar row), the two sealing rings are arranged at the two ends of the metal sleeve body, the grouting structure is formed by grouting materials grouted in a cavity between the metal sleeve body and the two sections of three-bundled-bar bundles, and the metal sleeve body is in a straight line shape or a fish-bellied shape; the two sections of three-bundled-bar bundles, corresponding to rebars, are distributed in the central axis of corresponding holes in the metal sleeve body; and a grout discharging hole and joint and a grout injecting hole and joint are formed in each side wall of the two ends of themetal sleeve body. The connecting method of the three-bundled-bar bundles comprises the following steps that 1, the sealing rings are mounted, the three-bundled-bar bundles are inserted in the metal sleeve body for positioning; 2, a grout discharging extension tube and a grout injecting extension tube are mounted (if necessary); 3, the grouting materials are grouted; and 4, curing is conducted. According to the full grouting sleeve for connecting of the three-bundled-bar bundles and the connecting method of the three-bundled-bar bundles, design is reasonable, construction is convenient, safe and economic, the connecting process of the three-bundled-bar bundles can be completed efficiently, simply and conveniently, and connecting performance is reliable.

Description

technical field

[0001] The invention belongs to the technical field of prefabricated concrete member construction, and in particular relates to a full grouting sleeve for three-joint tendon bundle connection and a three-joint tendon bundle connection method. Background technique

[0002] In order to reduce the self-weight of long-span and heavy-load concrete structural members in civil engineering fields such as construction engineering and bridge engineering, it is often necessary to control the cross-sectional dimensions of beams, slabs, columns and other members as much as possible during design, and there will be too many steel bars on the cross-section. Intensive conditions may lead to complex construction of concrete components and difficulty in controlling construction quality.

[0003] In the actual design and construction process, civil engineers have given the "joint reinforcement" reinforcement configuration method to solve the problem of too many and too dense re...
