Steel reinforced joint, steel reinforced assembly, and precast steel reinforced concrete body

Abstract

A reinforcing bar joint includes: cylindrical bodies each including an inner surface including a female thread part; joint members each including one end portion including a joint male thread part; and a connecting member configured to connect a pair of the joint members which face each other, such that the pair of the joint members are allowed to move in the longitudinal direction and in an orthogonal direction to the longitudinal direction. Each of the cylindrical bodies includes one end portion configured to threadedly engage with a reinforcing bar male thread part at an end portion of one of reinforcing bars, and the other end portion configured to threadedly engage with the joint male thread part at the one end portion of a corresponding one of the joint members.

What is claimed is: 
     
         1 . A reinforcing bar joint configured to connect end portions of a pair of reinforcing bars to each other, the reinforcing bars facing to each other in a longitudinal direction of the reinforcing bars, the reinforcing bar joint comprising:
 cylindrical bodies each including an inner surface including a female thread part;   joint members each including one end portion including a joint male thread part; and   a connecting member configured to connect a pair of the joint members which face each other, such that the pair of the joint members are allowed to move in the longitudinal direction and in an orthogonal direction to the longitudinal direction,   wherein each of the cylindrical bodies includes one end portion configured to threadedly engage with a reinforcing bar male thread part at an end portion of one of the reinforcing bars, and the other end portion configured to threadedly engage with the joint male thread part at the one end portion of a corresponding one of the joint members.   
     
     
         2 . The reinforcing bar joint as claimed in  claim 1 , wherein each of the joint members includes a body part and the joint male thread part, and the connecting member and the joint members are removably coupled to each other by a fastener, with body parts of the pair of the joint members facing each other in the longitudinal direction. 
     
     
         3 . The reinforcing bar joint as claimed in  claim 2 , wherein the body parts of the joint members are interposed between a pair of connecting members. 
     
     
         4 . A reinforcing bar assembly comprising:
 a plurality of reinforcing bars arranged parallel to each other;   stirrups binding the plurality of reinforcing bars; and   cylindrical bodies each including an inner surface having a female thread part, wherein the cylindrical bodies are threadedly engaged with reinforcing bar male thread parts at end portions of the reinforcing bars, with the reinforcing bar male thread parts inserted into axially inner portions of female thread parts of the cylindrical bodies, and axially outer portions of the female thread parts exposed to outside of the reinforcing bar assembly.   
     
     
         5 . A precast reinforcing bar concrete body comprising the reinforcing bar joint as claimed in  claim 1 , wherein the cylindrical bodies of the reinforcing bar joint and the reinforcing bars are buried in concrete, and female thread parts at outer end faces of the cylindrical bodies are exposed at an end face of the concrete.
