Embodiment Construction

[0024] refer to figure 1 , figure 2 and image 3 , a telescopic steel bar connection kit, the main body of the kit includes a two-way screw sleeve 1, a forward screw seat 2, a reverse screw seat 20, a screw joint 3, a one-way screw sleeve 4 and a pin shaft 5; one end of the two-way screw sleeve 1 The inner thread of the thread is the same as the inner thread of the one-way thread sleeve 4, the thread of the forward screw seat 2, the screw joint 3 and the outer thread of the steel bar head 6 are the same, and the outer thread of the steel bar head 6 is rough-turned on-site All parts with the same thread teeth can be combined flexibly, and the ultimate goal is to use the main body of the kit to connect the two steel bar heads 6 to replace traditional welding and other processes. The combination of the main body of the kit has the following four typical connection structures:

[0025] One of the basic types:

[0026] The forward-rotating screw seat 2 and the reverse-rotating...

Abstract

The invention relates to a telescopic steel bar connecting external member. An external member body comprises a bidirectional thread sleeve, a forward spinning screw rod seat, a reverse spinning screw rod seat, screw connectors, one-way thread sleeves and pin shafts. An internal thread at one end of the bidirectional thread sleeve is consistent with internal threads of the one-way thread sleeves, and the forward spinning screw rod seat, the screw connectors and external threads headed and turned by steel bar heads are consistent. All the components in the external member can be organically combined, for example, the components are increased or reduced, two steel bar heads with different intervals are in butt joint, and the external member for connection of the steel bar heads on a construction site is provided. The telescopic steel bar connecting external member has the advantages that the combining mode is flexible, according to the needs for steel bar intervals, short-distance connection can be achieved by reducing the components, the needs for long-distance connection can be met by adding the components connected in series, and connecting clearances are tightened and eliminated through the bidirectional thread sleeve; connection is reliable, no deformation exists, the requirement for stress design can be met, the telescopic steel bar connecting external member meets the connection needs of two staggered steel bar heads with different included angles, and connection construction of the steel bars is greatly facilitated.

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...
