Telescopic Rebar Splice Kit

Abstract

The invention relates to a telescopic steel bar connection kit, the main body of which includes a two-way screw sleeve, a forward screw seat, a reverse screw seat, a screw joint, a one-way screw sleeve and a pin shaft; one end of the two-way screw sleeve The inner thread of the thread is consistent with the inner thread of the one-way thread sleeve, and the outer thread of the forward screw seat, screw joint and steel head pier is consistent; each part in the kit can be organically combined, such as adding or subtracting Parts, for the butt connection of two steel bar heads with different spacing, and provide a kit for the connection of steel bar heads at the construction site. The combination method is flexible. According to the requirements of the steel bar spacing, it can reduce the number of parts to form a short-distance connection, and can also increase the number of parts in series to meet the needs of long-distance connections. With the help of two-way threaded sleeves, it can achieve tension and eliminate connection gaps; the connection is reliable, no The amount of deformation can meet the stress design requirements, and it is suitable for the connection of two steel bar heads with dislocation and different angles, which greatly facilitates the construction of steel bar connection.

Description

Technical field:

[0001] The invention belongs to the field of building construction, in particular to a telescopic steel bar connection kit. Background technique:

[0002] With the promotion of construction industrialization, pilot projects are being carried out all over the country, and the most difficult problem to solve is the structural earthquake resistance and waterproofing. The solution given by the experts is that beam-column joints, beam ends and beam ends, between plate ends and plate ends, between plates and beam-columns are cast-in-place, and beam-slab surfaces are laminated and cast-in-place. But the difficulty lies in the butt joint of the force-transmitting steel bars between the concrete prefabricated components. If the welding scheme is used, the welding quality is difficult to meet the requirements due to the extremely limited operating space, and it is labor-intensive and time-consuming; if the scheme of excessive reinforcement plus traditional spiral pip...
