Eccentric wheel offset reinforcing bar connector

Abstract

The invention discloses an eccentric wheel offset reinforcing bar connector. The eccentric wheel offset reinforcing bar connector is used for connecting a first reinforcing bar with deviation and a second reinforcing bar with deviation, and comprises an eccentric wheel, a first tension member, an opening connecting clip, a first nut, an intermediate connecting rod, a second nut, a first end anchor plate, an anchor sleeve, a second end anchor plate and a second tension member; the open end of the opening connecting clip is connected to the eccentric wheel, and the other end of the opening connecting clip is connected to the first reinforcing bar; the first nut is anchored to the eccentric wheel; the intermediate connecting rod is connected to the first nut and a second nut, the anchor sleeve is connected to the first end anchor plate and the second end anchor plate, the first end anchor plate and the second end anchor plate are anchored to the second nut in a front and rear mode, and the second end anchor plate is connected to the second reinforcing bar; the first tension member is disposed on the outer side of the eccentric wheel, and after the intermediate connecting rod and the first nut are inserted into the eccentric wheel, the first tension member is pulled to realize anchorage of the connector; and the second tension member is disposed outside the anchor sleeve, and the second tension member is externally pulled after the connector is anchored to realize tightening of the connector. The eccentric wheel offset reinforcing bar connector realizes the quick connection of the pre-buried offset reinforcing bars, and has a small overall size and a wide application range.

Description

technical field [0001] The invention relates to the technical field of steel bar connection, in particular to an eccentric wheel offset steel bar connector. Background technique [0002] In the current field of engineering construction, prefabricated buildings and modular construction of steel bars are becoming more and more common. The prefabrication of separate components and the modularization of steel bars inevitably lead to certain errors in the processing and production of steel bars. How to safely and reliably connect steel bars with construction deviations effectively has always been a problem. It is the key to prefabricated buildings. [0003] In order to solve the problem of steel bar connection in concrete structure assembly buildings, there are currently two common methods: wet connection and dry connection; in the wet connection scheme, in addition to the cast-in-place joint of the steel bar using the lap joint method, the most widely used is the grouting sleeve...

Problems solved by technology

[0003] In order to solve the problem of steel bar connection in concrete structure assembly buildings, there are currently two common methods: wet connection and dry connection; in the wet connection scheme, except for the cast-in-place joint of the steel bar using the lap joint method, the most widely used is the grouting sleeve, Grout-anchor lap joints and other forms, these joints generally have disadvantages such as strong construction concealment, difficult quality control, lack of reliable detection methods and inspection standards; another dry connection mainly refers to bolted connections, because bolted connections require a The operating space for bolt installation and fastening, this operating space not only greatly reduces the concrete connection area at the joint position, weakens the connection strength, but also makes the bolt connection only suitable for the connection of steel bars on the surface of the component, and the application range is quite narrow
