Flatness control structure of steel cover beam support base plate and installation method
The invention provides a steel cover beam support base plate flatness control structure and an installation method, and belongs to the technical field of bridge engineering construction. The problems that a portable milling machine cannot be used and the support base plate cannot be integrally machined under the limited space are solved. According to the technical scheme, the method comprises the following steps that firstly, a bottom-layer support base plate is positioned and marked; step 2, pre-mounting a bottom-layer support base plate; step 3, measuring elevation data of the bottom-layer support base plate; fourthly, allowance machining is conducted on the upper surface of the bottom-layer support base plate; fifthly, a bottom-layer support base plate is installed; and sixthly, an upper-layer support base plate is installed. The machining method has the beneficial effects that according to the scheme, the machining precision of the support base plate is improved through the allowance machining mode that the allowance line is integrally marked on the preassembled support base plate; the precision of reset installation of the support base plate is improved through the installation inspection line; and through machining of the single-layer single support base plate, the machining period of traditional overall lineation machining of the support base plate is shortened, and machining is more convenient.
本发明提供了一种钢盖梁支座垫板平面度控制结构及安装方法，属于桥梁工程施工技术领域。解决了空间受限下，便携式铣床无法使用，支座垫板无法整体加工的难题。其技术方案为：包括如下步骤：步骤一，底层支座垫板定位划线；步骤二，底层支座垫板预安装：步骤三，底层支座垫板标高数据测量；步骤四，底层支座垫板上表面余量加工；步骤五，底层支座垫板安装；步骤六，上层支座垫板安装。本发明的有益效果为：本方案通过预装支座垫板整体划余量线的余量加工方式，提高了支座垫板的加工精度；通过安装检验线提高了支座垫板复位安装的精度；通过单层单块支座垫板的加工，缩短了传统整体划线加工支座垫板的加工周期，且加工更加便利。
