1、濟南防水http://m.1222777.com/介紹改變預留施工縫的支座支承情況,改為簡支支座,斷開負筋,調整此處板底筋(配筋量增大)和負筋(配筋量減小)。這樣,改變了樓板受力狀態,應重新設計計算,并征得設計單位同意。
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、濟南防水談到降低標高,此調整影響結構抗震性能很小,因為樓房水平方向靠圈梁拉結,豎向靠構造柱拉結。
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、濟南防水建議施工縫處澆筑混凝土時,可先澆筑圈梁混凝土,后澆筑現澆板混凝土,直接在截面處設置現澆板的垂直側模,將混凝土振搗密實。
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、濟南防水http://m.1222777.com/提醒大面積樓層結構設計時,應該沿縱向每隔20米左右設置一條施工縫,這樣做既能保證原設計力學假定,又能消除現澆板收縮裂縫,同時也能解決由于屋面現澆板熱脹引起的頂層窗洞口處出現八字縫。
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.
