Description of the invention (The present invention is a kind of worm-stretching technique. It uses the cold forging method, especially-a kind of tapping and hardening in the steel woven structure to change the design of the reinforcing steel group. In order to achieve the method of strengthening the splicing ends of reinforced steel bars, the construction workers now give up traditional splicing methods and use tapped hydraulic casings $ and σ method, which are not included in the steel bars. The main cost is the cost of welding, gunpowder melting and friction dissolving. The main two are: import must be obtained, and the production speed is slower 1 /, the shortcomings of land resources, and the car teeth method, threading, /疋 The steel bar is connected with n-rolling method and reinforced expanding head tapping method. After the general car booking as shown in the fourth figure, the tapping locomotive tooth is used; energy = 5 1) The outer skin of the steel bar must be removed before a The loss of cross-section circle diameter and the stress of the indentation of the teeth (^ 1) make the reinforcing steel (5 plus 4, which uses 俨! 士 哭 Γ R 9 ,,) the strength drops rapidly) The test result is not tooth loss, It is the fracture at the processed part. As shown in the fifth figure, the hobbing method is After the steel bar (60) is cut, use a peeler to cut out the tapered surface (6 workers) at the continuation end and then perform the rolling operation (62) '. The surface of this rolling method is smooth and the surface of the screw teeth Work hardening and the formation of mechanical fibrous structure will be more important than the traditional production of strong teeth. However-rhyme rebar-(Miscellaneous ^; the reduction of the broken area and the strength of the joints' cannot be used to increase the strength to The original strength of the original steel base material, plus the rolling process is prone to the wrong tooth changes

Description of the Invention (1) The second crew must pay great attention to it, otherwise only the products with the tooth profile (63) without thread will be produced, and the problem will be broken at the teeth and the processing place. In the elephant, the flaring and tapping method shown in the figure often occurs. In the construction process, after the steel bar (70) is cut, the steel (0) is clamped by the mold (80). The forging or cold forging die (8 丨) is pushed so that the processing area of the turning tool is enlarged to the original enlarged portion (71) of 15% to 18%, and then the turning operation is performed, so that the continuous end of the steel bar has a screw tooth (72) , Which uses the base stress multiplied by the area equal to the tensile force, and when the enlarged section of the rebar is larger than the original parent face by the block, it can be known by definition that it must be greater than the strength of the original parent material, but when the test is performed on site The result is also fracture. The reason is that the domestic manufacturers of steel bars produce specifications and specific gravity standards. However, due to the different patterns on the bamboo bars, the diameter of the bars is slightly different. In addition, the original steel embryos come from different countries. The manufactured yield strength is 46kg / mm2 ~ 64kg / mm2, and the elongation rate is nEu% ~ 20Eu%, etc. ^ Very large, while the expanded head tapping method only focuses on the expansion of the broken area, but ignores the yield strength and elongation of the steel bar, which is prone to excessive Caused by plastic working. Reinforcement system embrittlement and other issues' plus the expansion area of the reinforcement 帛 15% ~ 18%, prone to tissue lesions, plus cold forging is prone to eccentricity and not easy to tap, so the quality of its products is very unstable . In view of this, the inventor then carefully studied and innovated the design, and in the meantime, "worked out-finally invented a" steel province to obtain high-strength joints to obtain high strength "to improve the safety of the project" screw-type steel bar taper Method "(cns) a4 ^ m ---- I .--- r --- • installation (please read the precautions on the back before filling this page) ---- I '(210 x 297 mm) 5 2.

Easy to enter the car's teeth can be achieved to improve the stability of processing. Therefore, the characteristics of the method are explained in detail through the above method of the invention It consists of the following steps: First, the first step is to cut the continuation of the reinforcing bar, and the cold continuity of the continuity of the second clamping line of the steel bar is reduced and compacted. The third step is to reinforce the splicing ends of the reinforcing bars and merge the screws, so that the metal of the splicing ends of the reinforcing bars crystallizes. The slip phase can promote the differential displacement of metal crystals, which can make the metal crystals mutually interact with each other. ^ Both the internal stress of the material at the part, and the reinforcement of the reinforcing bar splicing end =, and weaving and strengthening ', which can make the reinforcing bar splicing end form. Round rods can be easily achieved; the processing stability of the teeth, and can increase the strength of the continuous connection of the steel mold, so that the workers and private women can obtain a great improvement in all-round effect. In summary, the present invention "Screw-reinforced Retractable Head Tapping Method" is: Created with the high degree of the technical idea of natural law, which can increase the strength of the second end of the rebar, which meets the requirements of the invention patent, and applies according to the law.
