Because the screw system will reduce the cross section of the steel bars, the screw-type steel bars that have not been strengthened will not pass the strength test. There are several methods used by the industry to strengthen the splicing type of steel splicing joints: 1. Apply fire at the end of the steel bar or add high amounts of carbon, fierce or vanadium to increase the hardness, so that The strength of the ends of the screw teeth of the steel bar is higher than other parts. 2. Squeeze the ends of the bars to increase the density of the ends of the bars to increase the strength of the ends of the bars. —3 — This paper size is applicable to China National Standards (CNS) A4 (210X297mm) V.

Use extrusion technology to increase the cross-sectional area of the end of the steel bar, and increase the area of the end of the steel bar. Among them, due to the complex process of adding foreign elements such as carbon, fierce, or starvation, it is impossible to carry out field construction. Generally, the steel bar is finished with zen fire or adding high amounts of carbon, fierce, or vanadium before leaving the factory. Later, the industry needs to carry out the work of turning teeth. In addition, the method of squeezing the waist to increase the density or increase the cross-sectional area often changes the shape of the end face of the steel bar. Due to the strength reinforcement method of the traditional screw-type reinforcing bar coupler, due to various reasons, the reinforcing bar must complete the strength reinforcement work before the turning. After the reinforcing bar has completed the strength strengthening work, it is really necessary to perform the turning work. Not easy, because the surface strength of the steel bar is increased, which makes the machining of turning teeth more difficult; even if the work of the turning teeth is successfully completed, the surface of the thread after the turning is damaged, and the surface of the thread after molding does not have excellent strength, and The uneven strength is easy to cause stress concentration, and no matter which strength reinforcement method can not be used in the existing concrete construction, it is easy to cause the trade-off of the amount. In addition, the increased hardness of the entire section of the end of the reinforcing bar will relatively weaken the ductility of the reinforcing bar, and it will be difficult to improve the tensile or compressive strength. The author has many years of experience in the design and production of various types of steel bar connectors, and knows the advantages and disadvantages of various steel bar connectors, especially in the research work of screw-type steel bar connectors, and I hope to develop One is different from the traditional strength reinforcement method of the spiral toothed steel connector, to improve the lack of the Fu Tong strength reinforcement method, in an attempt to increase the practical value of the spiral toothed steel connector, and enhance the industry's progress. —4 A paper size using the Chinese National Standard (CNS > A4 size (210X297 mm) i -------- ^-(Please read the precautions on the back before filling this page) 1- * Line A7 B7 V.
