非預(yù)應(yīng)力離心混凝土樁制造技術(shù)

本發(fā)明專利技術(shù)的非預(yù)應(yīng)力離心混凝土樁，其特征在于包括離心混凝土樁身、非預(yù)應(yīng)力主筋、螺旋箍筋、2塊端板，所述非預(yù)應(yīng)力主筋縱向分布并焊接或綁扎在螺旋箍筋上，非預(yù)應(yīng)力主筋兩端分別焊接或經(jīng)錨固孔錨固在2塊端板上。主要是在現(xiàn)有的預(yù)應(yīng)力離心混凝土樁的基礎(chǔ)上，將鋼筋骨架上能縱向貫穿整個(gè)骨架的預(yù)應(yīng)力主筋改為非預(yù)應(yīng)力主筋，在生產(chǎn)工序中使用離心成型工藝，通過(guò)離心，將部分多余水分被帶出，并使混凝土更加致密。充分發(fā)揮了離心樁和實(shí)心方樁的優(yōu)點(diǎn)，是一種豎向承載力高、樁基水平承載力也高、能滿足抗震要求的離心混凝土樁。同時(shí)，還由于取消了預(yù)應(yīng)力施加工藝，比現(xiàn)有的生產(chǎn)預(yù)應(yīng)力離心混凝土樁的生產(chǎn)方法簡(jiǎn)便，生產(chǎn)效率更高。?

Non prestressed centrifugal concrete pile

Non prestressed centrifugal concrete pile of the invention, which is characterized by comprising the centrifugal concrete pile, prestressed reinforcement, non spiral stirrups, 2 end plates, longitudinal distribution and prestressed reinforcement welding or banding in the non spiral stirrups, non prestressed reinforcement are respectively welded or by anchoring anchoring holes in 2 block end board. Is mainly based on the prestressed centrifugal concrete pile on the prestressed bar of the reinforced skeleton can vertically through the entire skeleton to non prestressed reinforcement, in the production process used in centrifugal casting process, by centrifugation, will be part of the excess water was brought out, and make concrete denser. Taking full advantage of the advantages of centrifugal pile and solid square pile, it is a kind of centrifugal concrete pile with high vertical bearing capacity, high horizontal bearing capacity, and can meet the seismic requirements. At the same time, because the prestressing force is applied, the production method of the prestressed centrifugal concrete pile is simple and convenient, and the production efficiency is higher. ?
