Self-locking mechanical coupling sleeve

Abstract

The invention discloses a self-locking mechanical connecting sleeve. The self-locking mechanical connecting sleeve comprises a first sleeve pipe part and a second sleeve pipe part, wherein the secondsleeve pipe part comprises a second steel bar connector, a thimble, a first sleeve pipe, a second sleeve pipe, a first clamping piece and a second clamping piece; the thimble is connected to one end of the second steel bar connector, one end portion of the second steel bar connector is sleeved with the first sleeve pipe, and one end portion of the first sleeve pipe is sleeved with the second sleeve pipe; the first clamping piece is arranged on the inner circumferential wall of the second sleeve pipe, and the second clamping piece is arranged on the inner circumferential wall of the first sleeve pipe. The self-locking mechanical connecting sleeve has the beneficial effects that through a self-locking mode, under the action of pressure, the connection of steel bars is realized, the pressurecan be the self-gravity of prefabricated components or the pre-pressure, the use is convenient, compared with a grouting sleeve, the connection performance is no longer determined by the quality and compactness of grouting material, and at the same time the complicated grouting construction process is cancelled.

Description

technical field [0001] The invention relates to the technical field of fabricated structure construction, in particular to a self-locking mechanical connection sleeve. 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-place construction ...

Problems solved by technology

The reliability of this connection not only depends on the sleeve itself, but also needs to be filled with grout in the cavity to achieve reliable anchoring of the steel bars. At present, the density of the grout cannot be effectively detected, so it must be passed. Strict construction process management to ensure the density of grouting, which also leads to a slightly complicated construction process, and requires construction personnel with excellent practicing ability to operate

[0005] To sum up, the grouting sleeve connection is currently the most commonly used connection form of the assembled structure, but its performance depends not only on the material (grouting sleeve, grouting material) itself, but also on the process management, so that the grouting sleeve The reliability of the connection form takes part in artificial uncertain factors
