Abstract

The invention relates to the field of bridge construction, and particularly relates to a side arch rib construction method and a side arch rib. The side arch rib construction method comprises the following steps that a foundation of the side arch rib is pretreated, and prepressing inspection is conducted on the foundation; a mounting bracket of the side arch rib is erected on the foundation, and apreset arc-shaped surface is formed at the top end of the mounting bracket during erection; a side arch rib formwork is mounted on the mounting bracket, and concrete is poured in a layered mode to form the arch rib; and a formwork of a mounting end cross beam at the upper end of the arch rib is extended, and concrete is poured in a layered mode to connect the arch ribs on the two sides of a bridge in the transverse direction. According to the side arch rib construction method and the side arch rib, the preset arc-shaped surface is formed at the top end of the mounting bracket, so that the erected mounting bracket can be matched with the bending shape of the arch rib, thus effective supporting of bracket stand columns to the side arch rib is ensured, and the compactness and strength of theconcrete are ensured through the layered pouring mode.

Description

【Technical Field】 [0001] The application relates to the field of bridge construction, in particular to a side arch rib construction method and a side arch rib. 【Background technique】 [0002] With the rapid development of my country’s infrastructure construction, the requirements for bridge construction are getting higher and higher. During bridge construction, certain structures of the bridge are often constructed into curved shapes, such as side arch ribs, which are used to bridge the sides of the bridge. The arch is supported. [0003] The existing construction method of side arch ribs often adopts the method of installing brackets, that is, after installing the brackets on the foundation, install the formwork on the brackets and pour concrete to form the side arch ribs. Due to the curved shape of the side arch ribs, it is difficult for the erected installation brackets to ensure effective support for the various parts of the side arch ribs to be poured, and the construction ado...
