Rebar connector for butt joint of prefabricated concrete members and butt joint method

Abstract

The invention discloses a rebar connector for butt joint of prefabricated concrete members and a butt joint method. The rebar connector is composed of a retaining nut, a hook-shaped lock, a string ring, a butterfly-shaped supporting plate and a screw lock connection rod. When a groove in the middle of the screw lock connection rod is buckled and the hook-shaped lock in a connection sleeve are buckled together, rebars of the two prefabricated concrete members are connected. Liquid high-strength binding agents are poured into the sleeve where the rebar connector is placed, the redundant binding agents overflow; and after the screw lock connection rod is inserted, and the screw lock connection rod and the sleeve are bonded into a whole after the binding agents are solidified,. Meanwhile, concrete on the connecting surfaces are also bonded through binding agents, and the problems that time for operation, such as welding, overlap joint, bolting and the like, of traditional connection end plates is long, connector cost is high, and connector strength is unreliable, are solved. According to the rebar connector for butt joint of the prefabricated concrete members and the butt joint method, construction operability is high, the member assembly degree is high, construction operation efficiency is high, engineering materials are saved, engineering cost is low, and the engineering implementation effect is good.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a connection method of steel bars and a butt joint method of assembled concrete components. Background technique [0002] The key to prefabricated buildings is the equal strength connection of reinforced concrete prefabricated components. In order to achieve equal strength connection, the main reinforcement must be butted. In order to make the prefabricated reinforced concrete members connect quickly and seamlessly, it is impossible to expose the main reinforcement of the force. The main reinforcement of the two prefabricated components is aligned outside the body, and then the concrete is poured to realize the connection of the two concrete members. This will not only increase the The workload is large, and the construction period is extended, the project cost is increased, and the rapid assembly of the building structure in the true sense has not been realized, so it...

Problems solved by technology

[0007] However, the snap ring assembly, under the action of external force, can radially expand the size of the snap ring, so that the elastically deformable snap ring fixture sleeved on the outer wall of the snap ring is also deformed outward, and then rely on the elastic force of the snap ring fixture It is very difficult to make the snap ring move radially inward and overcome the frictional resistance of the middle nut and the washer on the two end faces of the snap ring. On the card table of the connector, or snapped into place, it means that this connection is unreliable
