【正文】 特點(diǎn)：工藝簡(jiǎn)單可以預(yù)加工連接速度快同心度好，不受鋼筋含碳量和有無(wú)花紋限制等優(yōu)點(diǎn)。 特點(diǎn)：接頭強(qiáng)度高，性能可靠，能夠承受高應(yīng)力反復(fù)拉壓載荷及疲勞載荷。 鋼筋混凝土結(jié)構(gòu)中鋼筋連接綜述 改革開(kāi)放以來(lái)，隨著 國(guó)民經(jīng) 濟(jì)的快速、持久發(fā)展，各種鋼筋混凝土建筑結(jié)構(gòu)大量建造，鋼筋連接技術(shù)得到很大的發(fā)展。 嚴(yán)格控制板面負(fù)筋保護(hù)層厚度。 板負(fù)筋下沉產(chǎn)生的裂縫?！痘炷两Y(jié)構(gòu)工程施工質(zhì)量驗(yàn)收規(guī)范 》規(guī)定，混凝土強(qiáng)度達(dá)到 ，不得在其上踩踏或安裝模板及支架。s Position will be two solid steel bars linked Characteristic: Connect intensity to be high, performance reliable, can bear high stress draw and pigeonhole the load and tired load repeatedly. Easy and simple to handle, construction fast, save energy and material, prehensive economy profitable, this method has been already a large amount of application in the project. Applicable scope : Suitable for Ⅱ , Ⅲ , Ⅳ grade reinforcing bar (including welding bad reinforcing bar ) with ribbing of Ф 18 50mm, connection between the same diameter or different diameters reinforcing bar . must squeeze link Extruders used in the covers, reinforced axis along the cold metal sleeve squeeze dedicated to insert sleeve Lane two hot rolling steel drums into a highly integrated mechanical linking methods. Characteristic: Easy to operate and joining fast and not having flame homework , can construct for 24 hours , save a large number of reinforcing bars and energy. Applicable scope : Suitable for , set up according to first and second class antidetonation requirement proof armored concrete structure ФⅡ , Ⅲ grade reinforcing bar with ribbing of hot rolling of 20 32mm join and construct live. cone thread connecting Using cone thread to bear pulled, pressed both effort and selflocking nature, undergo good principles will be reinforced by linking into coneprocessing thread at the moment the value of integration into the joints connecting steel bars. Characteristic: Simple , all right preparatory cut of the craft , connecting fast, concentricity is good, have pattern person who restrain from advantage reinforcing bar carbon content. Applicable scope : Suitable for the concrete structure of the industry , civil building and general structures, reinforcing bar diameter is for Фfor the the 16 40mm one Ⅱ , Ⅲ grade verticality, it is the oblique to or reinforcing bars horizontal join construct live. conclusions These are now monly used to connect steel synthesis methods, which links technology in the United States, Britain, Japan and other countries are widely used. There are different ways to connect their different characteristics and scope of the actual construction of production depending on the specific project choose a suitable method of connecting to achieve both energy conservation and saving time limit for a project ends.
