pvc草坪护栏横隔梁设计
浏览:发布日期:2017-12-06
升级pvc草坪护栏横隔梁设计,笔者采用上加横隔梁的方法弥补波形梁板厚度的不足,提高pvc草坪护栏的拦阻能力,避免车辆在碰撞过程中骑跨pvc草坪护栏。
Upgrading the design of PVC lawn guardrail cross beam, the author uses the method of adding cross beam to compensate for the lack of wave beam thickness, improve the barrier capacity of PVC lawn fence, and avoid vehicle riding across PVC lawn guardrail during the collision process.
在立柱中浇筑自密实混凝土,并配置纵向钢筋,以提高立柱整体抗弯能力; 在原立柱基础上加横隔梁,弥补波形梁板厚度的不足,并提升pvc草坪护栏抗拉抗剪性能。
The self compacting concrete is poured into the column and longitudinal reinforcement is installed to improve the overall bending resistance of the column. On the basis of the original column, the diaphragm is added to make up for the insufficient thickness of the corrugated beam and enhance the tensile and shear performance of the PVC lawn guardrail.
从3 个方面对旧路波形梁pvc草坪护栏立柱进行安全性提升: 增加立柱的埋置深度,以保障pvc草坪护栏在碰撞过程中pvc草坪护栏立柱土基与立柱固结点的稳定性。

The safety of old wave beam PVC lawn guardrail column is improved from 3 aspects: increasing the embedment depth of the column to ensure the stability of the PVC lawn guardrail during the collision process, and the stability of PVC lawn guardrail column foundation and column.
升级改造方案最大限度的利用了《94 规范》中的波形梁pvc草坪护栏,节省造价,通过增加配筋和增加埋深,使pvc草坪护栏防撞能力满足标准要求。
The upgrading and transformation scheme maximizes the utilization of the wave beam PVC lawn guardrail in the 94 specification, which saves the cost. By increasing the reinforcement and increasing the buried depth, the PVC lawn guardrail meets the standard requirements.
pvc草坪护栏通过横隔梁与立柱连接处增加传力途径,有利于碰撞力向多跨波形梁传递,减小了波形梁立柱受力集中。
By increasing the transmission way through the connection of the cross beam and the column, it is beneficial for the collision force to transfer to the multi span wave beam and reduce the force concentration of the wave Liang Lizhu.
