框架结构的施工缝留得是否合理,对结构的整体性和刚性都有一定的影响,对于多层和高层建筑,这种影响是不可忽视的。框架结构留施工缝有两条基本原则,一是强柱弱梁,二是保证结点核心的混凝土的施工质量。下面分别进行介绍。一、强柱弱梁1.框架柱上一般不留施工缝,应将施工缝留在梁上。如图1所示复式框架,施工缝应留在框架梁 KH 上。施工缝留在梁上时,一般不留在框架梁
Whether the construction joints of the frame structure are reasonable or not remains to have a certain influence on the integrity and rigidity of the structure. For multi-storey and high-rise buildings, such influence cannot be ignored. There are two basic principles for retaining construction joints in the frame structure. One is the strong column weak beam, and the other is to ensure the construction quality of the core concrete of the joints. The following are introduced separately. First, the strong column weak beam 1. Frame column generally does not leave construction joints, construction joints should be left on the beam. As shown in Fig. 1 for the double frame, construction joints should be left on the frame beam KH. When construction joints are left on beams, they are generally not left on the frame beams.
