一种平整连接面的后置埋板施工技术分析

Construction Technology Analysis of a Rear Embedded Plate With Flat Joint Surface

本文以某修缮改造项目中钢结构安装工程为背景,阐述了如何解决常规后置埋板的后置锚栓突出连接面阻碍钢结构构件顺利就位安装的问题。研发应用了一种“平整连接面的后置埋板”施工技术,即在连接板上根据后置锚栓的位置开设凹槽,使得后置锚栓的紧固段位于凹槽内,避免后置锚栓的紧固段凸出连接板的表面,从而使得连接板与钢结构构件连接的一面相对平整,方便了钢构件的就位安装,防止了钢构件现场切槽、开口和补焊等工作,从而减少了现场焊接量和质量隐患,同时提高了钢结构安装工程的施工效率和可操作性。该施工技术值得在类似工程项目中参考借鉴和推广应用。

Based on the steel structure installation project in a renovation project,this paper describes that in order to solve the problem that the protruding joint surface of the rear anchor bolt of the conventional rear buried plate prevents the smooth installation of steel structure members,the project has developed and applied a construction technology of"rear buried plate with flat joint surface",that is,grooves are created on the connecting plate according to the position of the rear anchor bolt.The fastening section of the rear anchor bolt is located in the groove to avoid protruding the surface of the connecting plate,so that the connecting side of the connecting plate and the steel structural part is relatively flat,which facilitates the installation of the steel member,prevents the on-site grooving,opening and repair welding of the steel member,and thus reduces the amount of on-site welding and quality hazards.At the same time,the construction efficiency and operability of the steel structure installation project are improved,and the construction technology is worthy of reference and application in similar projects.
