Abstract

DC60 (08/06/42) with a purpose Of arrangement having a method for connecting the connecting end of the deformed bar Reinforced concrete that reduces running costs Will increase the ease of work To increase the mechanical holding force to the connection So that the interface can be connected Without destroying the structure of the steel structure of the connecting parts between the parts of the steel bar, the deformed bar works by means of And the connection structure of the deformed bar. By this invention, a method for connecting the deformed joints of the reinforced concrete is provided. That consists of steps Of the bend where the deformed bar reinforces the concrete At least at normal temperature, the connection end is bent, and forms a rolled thread around the surface. Outside of the connecting end of the deformed bar that has passed According to the steps of bending Where the ends are connected to the least part Will be bent at normal temperature in Appearance at the greatest diameter Of the connection end is equal to Or larger than the diameter of the body Cylinder of the deformed bar Or slightly smaller than the diameter of the deformed bar. Depending on the degree of use; And the process of rolling the roll creates a thread with a diameter equal to the diameter of the bent part around the surface. Outside of the connecting end of the deformed bar that passes through the process of bending.
