Abstract

The invention discloses a steel bar staggered connecting device and a connecting method thereof. Threads are arranged in a connecting sleeve, so that the friction force between steel bars and the sleeve can be effectively increased, and the connecting reliability is enhanced; limiting through grooves are formed in the connecting sleeves to limit the positions of the steel bars, it is guaranteed that longitudinal ribs of the steel bars are clamped into the limiting through grooves, transverse ribs (namely external threads of the steel bars) of the steel bars are tightly combined with internal threads of the connecting sleeves, and friction force is increased. The extrusion inserting rods are made of high-strength steel, the stress performance of the steel bars is fully utilized, and the two steel bars are extruded towards the two sides of the connecting sleeve so that the steel bars can not slide out of the connecting sleeve easily. The problem that an existing steel bar connection mode is inconvenient to use in steel bar connection of the fabricated building is solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a cross-connection device for steel bars and a connection method thereof. Background technique [0002] The mechanical connection of steel bars represented by connecting sleeves is more used in the connection of steel bars in cast-in-place reinforced concrete buildings. In prefabricated buildings, this kind of steel joints with reliable force and fast connection speed cannot be used because the precast steel bars cannot be rotated in the concrete members. [0003] Although the mechanical connection method of steel bars represented by extrusion sleeves can be used in prefabricated buildings, the sleeve extrusion pliers are large in size and are not convenient to be popularized and used in field installations. [0004] The information disclosed in this Background section is only for enhancement of understanding of the general background of the invention and should no...
