1、济南防水http://www.tianyujian.com/介绍改变预留施工缝的支座支承情况,改为简支支座,断开负筋,调整此处板底筋(配筋量增大)和负筋(配筋量减小)。这样,改变了楼板受力状态,应重新设计计算,并征得设计单位同意。
Jinan waterproof construction joints introduce change to reserve a seat support cases, instead of simply supported seat, disconnect negative reinforcement, reinforcement bottom plate adjustment here (reinforcement volume increases) and
negative reinforcement (reinforcement volume decreases). Thus, changing the floor by the force of the state, should be re-design calculations, design units and obtain consent.
2、济南防水谈到降低标高,此调整影响结构抗震性能很小,因为楼房水平方向靠圈梁拉结,竖向靠构造柱拉结。
Jinan waterproof Speaking lower elevation, this adjustment affects small seismic performance, because the building horizontally by Rachel ring beam, vertical structural columns by Rachel.
3、济南防水建议施工缝处浇筑混凝土时,可先浇筑圈梁混凝土,后浇筑现浇板混凝土,直接在截面处设置现浇板的垂直侧模,将混凝土振捣密实。
Jinan waterproof construction joints recommend pouring concrete ring beam can be pouring concrete, after pouring concrete Slab, Slab set directly in the cross section perpendicular to the side of the mold, the vibration compacting
concrete.
4、济南防水http://www.tianyujian.com/提醒大面积楼层结构设计时,应该沿纵向每隔20米左右设置一条施工缝,这样做既能保证原设计力学假定,又能消除现浇板收缩裂缝,同时也能解决由于屋面现浇板热胀引起的顶层窗洞口处出现八字缝。
Jinan waterproof remind large floor design, it should set about 20 meters along the longitudinal construction joints every one, so do not only ensure that the original design of the mechanical assumption, but also to eliminate Slab shrinkage cracks, but also to solve because of the roof Cast the hole at the top of the window plate thermal expansion joints caused by the emergence of character.
