Technical field
The present invention relates to a kind of replaceable screw shell reinforcing steel bar connecting device and construction technologies, belong to concrete component connection
Technical field.
Background technique
Existing reinforcing bar connection type mainly has three kinds of binding overlap joint, mechanical connection and welding.Reinforcing bar binding overlap joint connection
Mode is simple, construction efficiency is high；But reinforcing bar waste simultaneously is too big, skeleton is easily deformed, and application is limited,《Concrete
Code for structural design GB 50010-2010》Regulation：The Reinforcement of axial tension and small eccentricity tension member must not use
Bind lap joint.Welding operation splice operation is more direct, overlaps not applicable occasion supplemented with binding；Disadvantage
It is that welding equipment volume is larger, it is mobile inconvenient, it narrow space or is difficult to construct without crane, connector qualification rate is low, and power consumption is larger,
To construction process requirement height.The development trend of building industrialization is not met, it is not environmentally protective.
Mechanical connection mainly includes sleeve grouting interconnection technique, is press-connected, is threadedly coupled.Sleeve grouting connection application is wide
General, cost is relatively low；But there are the inadequate problems of the hidden danger blocked in spillage, sleeve and low-temperature construction intensity to be difficult to avoid that.
It is press-connected and avoids using all kinds of defects of grouting material, but extrusion equipment volume is big, high altitude operation is constant.
Thread connecting mode strength of joint is high, connector speed is fast, usability is strong, construction efficiency is high, section material, energy saving economy,
Advantage applied widely.But one is not easy to operate under existing thread connecting mode.From outer in existing thread connecting mode
Portion cannot observe determining reinforcing bar screw-in length, can not find in time when misplacing the case where, the company between reinforcing bar and sleeve
Reliability is connect to be difficult to ensure.Meanwhile reinforcing bar is screwed in when only one sleeve under existing thread connecting mode, it needs by spanner
Rotation or mobile whole reinforcing bar even two reinforcing bars, the connection that can not be applied between the structural elements of casting concrete.
Moreover, needing to process steel bar end by instrument when connecting the reinforcing bar of different-diameter under existing thread connecting mode, operate
It is cumbersome, can also have an adverse effect to the performance of steel bar end.Existing China's building aseismicity sets up defences the design principle of specification can be simple
It is described as " no damage in small earthquake, middle shake can repair, no collapsing with strong earthquake ", and reinforcing bar connection type does not consider its ductile performance mostly at present,
Shock resistance is weaker under limiting condition, it is difficult to meet requirements for fortification against earthquake.The present invention will make full use of thread connecting mode sheet
