1. Convenient connection: narrow space, compact arrangement, flexible bar operation. Convenient and efficient construction: steel bar connection sleeve, prefabricated factory, quality assurance: on-site rolling equipment can handle nearly 400 line head joints, a large number, such as buildings and basement movies have unparalleled advantages, construction without pollution, no fire operation, safety, environmental protection, adapt to various climatic conditions.

　　2. 易检测:施工不需要专门的检测设备，只需要根据情况提高外齿露丝接头的质量即可确定。适用范围:适用于所有抗震及非抗震钢筋混凝土结构工程的钢筋连接、弯钢筋、固定钢筋、钢笼、长钢筋等，且不能旋转。

　　2. Easy to test: Construction does not require special testing equipment, only need to improve the quality of the external teeth Ruth joint according to the situation can be determined. Scope of application: It is suitable for all aseismic and non-aseismic reinforced concrete structures, such as steel bar connection, bending steel bar, fixed steel bar, steel cage, long steel bar, etc., and can not rotate.

　　3.具有良好的力学性能,可靠连接:年底钢辊轧成形、冷作增强材料的过程,线程,增加钢的强度,使底部的螺纹直径小于基圆直径钢衬底材料的强度减弱的基质材料的冲击强度比,大关节的连接强度,基础材料,可以充分发挥其强度和延性。

　　3. Good mechanical properties, safe and reliable connection: end-of-year steel roll forming, cold-working reinforcement material process, threads, increase the strength of steel, so that the bottom thread diameter is smaller than the strength of the base circle diameter steel substrate material weakened matrix material impact strength ratio, joint strength of major joints, basic material, can give full play to its strength and ductility.

　　热轧钢筋直螺纹连接新的钢筋连接套筒技术、结构原则是钢筋的连接端纵肋和横肋皮切割方法,然后直接滚到普通的直螺纹,有特殊钢筋直螺纹连接套筒,形成钢筋的连接。

　　Hot-rolled steel bar straight thread connection new steel bar connection sleeve technology, structural principle is the steel bar connection end longitudinal rib and transverse rib skin cutting method, and then rolled directly to the ordinary straight thread, there are special steel bar straight thread connection sleeve, forming steel bar connection.

　　一、钢筋连接套原材料检验:从每批采购的各种规格的原材料中随机抽取三根钢条，分别对原材料进行切割打样。

　　1. Inspection of raw materials for reinforcing bar connecting sleeve: Three steel bars are randomly selected from raw materials of various specifications purchased in each batch, and the raw materials are cut and proofed separately.

　　二世。毛坯检验:毛坯生产各工序操作人员对加工后的毛坯尺寸进行逐一自检。质检员对成品毛坯的10%进行随机抽样检查。

　　King II. Rough inspection: Operators in each process of blank production check the size of the processed blank one by one. The quality inspectors inspect 10% of the blanks by random sampling.

　　3.螺纹检验:螺纹加工工人对加工后的螺纹进行逐一自检，合格产品只能放入待检区。质量检验员在被检验区根据连接套的连续生产情况进行检查。

　　3. Thread Inspection: Thread processors conduct self-inspection on the processed threads one by one, and qualified products can only be placed in the inspection area. The quality inspector inspects the continuous production of the connecting sleeve in the inspected area.
