Description
Technical Field
The invention relates to the technical field of steel bar connection and fixation in constructional engineering, in particular to a threaded clamping piece type steel bar connecting piece.
Background
Reinforcing steel bars (rebars) are steel materials for reinforced concrete and prestressed reinforced concrete, and have a circular cross section, and sometimes a square cross section with rounded corners. Comprises plain round steel bars, ribbed steel bars and twisted steel bars. The reinforcing steel bar for reinforced concrete is straight bar or wire rod-shaped steel for reinforcing steel bar for reinforced concrete, the shape of the reinforcing steel bar is smooth steel bar and deformed steel bar, and the delivery state is straight bar and wire rod. The plain round steel bars are actually small round steel and wire coils of ordinary low-carbon steel. Deformed bars are surface ribbed bars, usually with 2 longitudinal ribs and transverse ribs distributed uniformly along the length. The cross ribs are 3 types of spiral, herringbone and crescent shapes. The deformed reinforcing steel bar has larger bonding capacity with concrete due to the action of the ribs, so that the deformed reinforcing steel bar can better bear the action of external force. Reinforcing bars are widely used in various building structures. Especially large, heavy, light-duty thin-walled and high-rise building structures.
In order to facilitate assembly and use, the steel bars need to be fixedly connected, steel bar connection refers to a connection mode of the steel bars, and the connection mode of the steel bars mainly comprises four modes of binding and overlapping, mechanical connection, sleeve grouting connection and welding. The joint should be arranged at the position with smaller stress as much as possible, and the key part with larger stress of the structure should be avoided. And the anti-seismic design avoids the reinforcement range of the stirrups at the beam end and the column end, and if the stirrups must be connected in the area, mechanical connection or welding is adopted. Less connecting joints are preferably arranged on the same stressed steel bar in the same span or the same layer height, and 2 or more than 2 joints are not preferably arranged.
The current methods applied to the connection of the steel bars have different defects. The welding connection method cannot be used for high-strength steel bars, and axial deviation is easy to generate during welding of vertical steel bars; binding and lapping are generally used for plate steel bars and the like; the sleeve extrusion in mechanical connection has low efficiency and high cost, and the market is difficult to trace in recent years; at present, the market share of straight threads is much higher than that of conical threads, the straight threads are mainly used for connecting column beam steel bars in a cast-in-place structure, the whole steel bar needs to be rotated in a straight thread (conical thread) steel bar connecting mode so as to be screwed, and the field operation difficulty is large; the casing grouting scheme is a product developed aiming at the building industry, particularly the steel bar connection of a vertical prefabricated column, and comprises full casing grouting and half casing grouting (one half joint is in threaded connection with the other half for casing grouting), the size of a connecting mechanism is large, the occupied external space is large, the assembly stability and firmness fluctuation are large, the construction quality is greatly influenced by the grouting quality and position deviation, the mobility of the grouting slurry can generate bubbles, if the steel bar is not axially aligned with the casing, the steel bar is attached to the inner wall of the casing, so that the attachment part can form a bubble hollow core, the connection strength is seriously influenced (so that some local governments forbid prefabrication the vertical component), the connection quality is not easy to check, and the connection quality has no instant strength, long maintenance period, complex operation, construction progress is influenced, and the fatigue resistance under repeated stress is poor. Therefore, the assembly type building construction urgently needs a brand new steel bar connection mode to solve the current problems, improve the construction efficiency and ensure the quality stability.
