民用和公共建筑中,厨厕间常要留置一些预留孔。按常规是每层楼板支模完毕后,根据放线员弹出的墙体轴线画出预留孔的位置,将木模或砖块放准即可。但是由于绑扎钢筋、搭设运输道、电工留管、振捣混凝土等多道工序综合施工,安放的预留孔模板极易移动。为消除此项通病,我们研制了“地梁标志控制法”,结合“铁模捆绑法”施工,现将方法介绍如下。一、地梁标志法1.将厨厕间等地面预留孔位置的轴线,分别延长到两道外纵墙和两道外横
In civilian and public buildings, some reserved holes are often reserved in the kitchens and toilets. According to the conventional method, after the floor molding of each floor is completed, the position of the reserved hole is drawn according to the axis of the wall ejected by the release person, and the wooden mold or the brick can be placed accurately. However, due to the integrated construction of multiple processes such as tying steel bars, setting up a transport road, leaving an electric pipe, vibrating concrete, and the like, the prepared hole template can be easily moved. In order to eliminate this problem, we have developed a “ground beam sign control method” combined with “iron mold binding method” construction. The method is now described as follows. First, the ground beam sign method 1. To extend the axis of the ground reserved hole positions such as kitchen and toilet rooms to two outer vertical walls and two horizontal crossways respectively.
