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. 易檢測(cè):施工不需要專門的檢測(cè)設(shè)備，只需要根據(jù)情況提高外齒露絲接頭的質(zhì)量即可確定。適用范圍:適用于所有抗震及非抗震鋼筋混凝土結(jié)構(gòu)工程的鋼筋連接、彎鋼筋、固定鋼筋、鋼籠、長(zhǎng)鋼筋等，且不能旋轉(zhuǎn)。

　　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.具有良好的力學(xué)性能,可靠連接:年底鋼輥軋成形、冷作增強(qiáng)材料的過程,線程,增加鋼的強(qiáng)度,使底部的螺紋直徑小于基圓直徑鋼襯底材料的強(qiáng)度減弱的基質(zhì)材料的沖擊強(qiáng)度比,大關(guān)節(jié)的連接強(qiáng)度,基礎(chǔ)材料,可以充分發(fā)揮其強(qiáng)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.

　　熱軋鋼筋直螺紋連接新的鋼筋連接套筒技術(shù)、結(jié)構(gòu)原則是鋼筋的連接端縱肋和橫肋皮切割方法,然后直接滾到普通的直螺紋,有特殊鋼筋直螺紋連接套筒,形成鋼筋的連接。

　　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、鋼筋連接套原材料檢驗(yàn):從每批采購的各種規(guī)格的原材料中隨機(jī)抽取三根鋼條，分別對(duì)原材料進(jìn)行切割打樣。

　　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。毛坯檢驗(yàn):毛坯生產(chǎn)各工序操作人員對(duì)加工后的毛坯尺寸進(jìn)行逐一自檢。質(zhì)檢員對(duì)成品毛坯的10%進(jìn)行隨機(jī)抽樣檢查。

　　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.螺紋檢驗(yàn):螺紋加工工人對(duì)加工后的螺紋進(jìn)行逐一自檢，合格產(chǎn)品只能放入待檢區(qū)。質(zhì)量檢驗(yàn)員在被檢驗(yàn)區(qū)根據(jù)連接套的連續(xù)生產(chǎn)情況進(jìn)行檢查。

　　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.
