鋼筋錨固技術產品

2021/03/07 產品技術 4248

鋼筋與混凝土之間的錨固是混凝土結構中的基本問題之一，它對結構中鋼筋強度的發(fā)揮、裂縫控制、配筋構造以及結構的安全性均有重要影響。

產品介紹產品規(guī)格

? ? ? ? 在鋼筋混凝土結構中，鋼筋目前常用的錨固方式是使用末端帶彎鉤的構造，90°或135°彎鉤鋼筋雖然在一定程度上加強了鋼筋錨固性能、減小了錨固長度，但是彎折或較大的彎弧半徑構造要求經常帶來許多問題，如造成梁-柱節(jié)點區(qū)鋼筋擁擠, 彎折或彎鉤與其他鋼筋的布置互相干擾,構件尺寸不能滿足錨固長度要求等等。在使用大直徑鋼筋時，這些矛盾更加突出。而鋼筋機械錨固技術能很好地解決這個問題，在保證鋼筋機械錨固性能的基礎上，優(yōu)化了鋼筋錨固條件，減少了鋼筋錨固長度，節(jié)約了錨固用鋼材，方便施工，提高混凝土澆筑質量。同時，鋼筋機械錨固也是建筑工業(yè)化、鋼筋部品化施工所不可或缺的產品技術。

應用場

代替?zhèn)鹘y(tǒng)彎筋，用于框架結構梁柱節(jié)點；
代替?zhèn)鹘y(tǒng)彎筋和箍筋，用于簡支梁支座；
用于橋梁、水工結構、地鐵、隧道、核電站等各類混凝土結構工程的鋼筋錨固；
建筑工業(yè)化中的（構建、鋼筋）部品鋼筋彎筋錨固處；
用作鋼筋錨桿(或拉桿)?的緊固件。

產品優(yōu)勢

質量可靠 --- 錨固性能好，可充分發(fā)揮鋼筋強度，有利于更高強度鋼筋的使用；
簡單高效 --- 工藝簡單，工效高，螺母與墊片合二為一，與鋼筋直螺紋連接，操作方便，加快鋼筋工程施工速度；
節(jié)能降耗 --- 可減少或取消鋼筋錨固長度，節(jié)約40-50%的錨固用鋼材，降低鋼筋成本；
提高質量 --- 克服傳統(tǒng)彎筋錨固擁擠和混凝土澆筑困難問題，提高工程質量；
前景廣闊 --- 是建筑業(yè)十項推廣應用新技術之一，是北京市綠色建筑適用技術之一；
