Reinforced concrete unit pier block using prestressed concrete steel wire assembly and H-beam

摘要

PC strand assembly and construction method, prefabricated reinforced concrete pier RC unit pier blocks and by Using the H-beam according to the present invention is, of multiple upper surface when forms a concave portion to be in the H beam inserted into the convex portion forming cross-section H-beam was created by installing the installation, obtain and install, install assemble reinforcement along the old PC strand installation of the outer principal surface to a plurality of PC strand installation sphere be the PC strand assembly inserted in the outer principal surface of the center and the end surface, and placing the curing of concrete and reinforced concrete unit blocks and pier; Embedded install support into the pier foundation of concrete, and that over a plurality of stud bolts to install the H beams installed over the H-beam front welding and installation H beam after install the PC strand anchorage fixing the PC strand for PC strand assembly sphere and PC strand installation sphere with the reinforcement to the concrete unit inserting the H-beam and the PC strand assembly of the pier block arranged to add location projections of the RC unit pier block the pier foundation concrete upper subjected to grouting the H beams installed obtain installed and the connecting portion, the sealing after the installation is formed by repeatedly laminating the process of injecting the epoxy pier pillars and; By installing insert coping block bottom with a concave portion connected to the insertion block, the old PC strand installation sphere H-beam installation formed in seeing portions of the pier pole RC unit pier blocks of the top of the coping block so that copings block bottom and the recess is in close contact connection relates to the construction, prefabricated reinforced concrete pier while tension the PC strand after mounting to the upper reinforced concrete units pier block fixing the PC strand for PC strand anchorage is installed in the groove of the upper coping blocks and installed by grouting filled in coping block upper groove .
