Method for constructing cast coping part through multi-phase strain

Abstract

The invention relates to a method for constructing a cast coping part through multi-phase strain. The method comprises the steps of: manufacturing a primary segment block by forming more than one row of first lateral casings on a set position of the primary segment block when the primary segment blocks are superposed on the upper end of the blocks as the pier components, manufacturing an auxiliary segment block by matching with the dies on two sides of the primary segment block and forming second lateral casings corresponding to the first lateral casings on the auxiliary segment block, guiding the longitudinal tension through the longitudinal pre-stressed reinforcing steel in the longitudinal casings of the primary segment block after lifting and superposing the primary segment blocks on the upper end of the blocks as the pier components, and guiding the lateral tension through the lateral pre-stressed reinforcing steel in the inserted first and second lateral casings after lifting and combining the auxiliary segment blocks on two sides of the primary segment blocks having the guided longitudinal tension.

Description

technical field [0001] The present invention relates to the construction method of the prefabricated cover beam part, especially relates to the construction method of the prefabricated cover beam part adopting multi-stage tension. Transverse tension is introduced between the blocks, and a new block is made by using the side of the formed block as a matching mold when making adjacent blocks. Background technique [0002] In order to support the main girder at the upper part of the pier, a cap beam part having a width corresponding to the width of the bridge is formed at the upper end of the module part. Conventionally, when construction was performed sequentially from the bottom of the pier, concrete was poured by assembling and setting a mold on the top of the pier, and the capping beam portion of the top of the pier was constructed by removing the mold after the concrete was cured. [0003] On the one hand, the aforementioned construction methods have recently been reduced...

AI Technical Summary

Problems solved by technology

[0014] However, the lightweight cover girder of the bridge needs to be formed into a cover girder having a width equal to the width of the bridge, so it is difficult to move after production, and it cannot actually be applied to other places other than bridges due to its weight.
