Reinforcing

Abstract

Reinforcing is disclosed that comprising a reinforcing bar extending along a portion of the length of the reinforcing and a termination extending along an end portion of the reinforcing. The termination is disclosed as being permanently bonded to the reinforcing bar preferably by a friction welding process so as to form an integral connection. The termination has a body extending in a longitudinal direction between opposite first and second ends, and a lateral engagement face formed on the body. In use the first end is joined to an end the reinforcing bar, and the engagement face incorporates locking formations thereon arranged to interfit with a complementary shaped termination to form an interlock arranged to accommodate loading applied in the longitudinal direction.

Description

technical field [0001] The present invention generally relates to reinforcing bars of concrete or other cementitious structures, and more particularly to connections between reinforcing bars as described above and below. However, it is worth noting that the present invention has a wide range of applications and can be applied to the connection of steel bars and other rigid objects such as iron plates and the like. Background technique [0002] In construction, concrete structures (such as walls, floors, slabs, and columns) are structures formed by placing reinforcing bars, such as steel bars, in an area followed by pouring concrete therein. These bars are supported in predetermined locations and it is often necessary to connect multiple bars to each other to ensure that the reinforcement not only sits properly but also transfers the load through the connection so that the bars are in tension or compression over most or even their entire length . [0003] In the past, metal...

Problems solved by technology

If these properties are not within a certain tolerance range, the joint structure will obviously affect the final structure, for example, if the longitudinal slip is too large, it will cause local cracking and increase the risk of corrosion, and may cause excessive deformation.

If the major parts of the connecting structure and reinforcement are not flexible enough, local stress concentrations will be induced which can lead to severe failure of the connection

[0007]The use of separate connectors, such as the above-mentioned threaded sleeves, creates the risk of a mismatch between the reinforcing bars and the sleeves where there are steel bars of different strengths at the site, and , the use of a sleeve structure requires a large space between components for easy installation, which in turn leads to excessive longitudinal slippage under load

And there is also a constant risk that the connection is not sufficiently secured in place, which will break the connection
